Other aspects of the invention can be found in the dependent claims.

According to one aspect of the present application, a drying apparatus is provided for drying a material. The drying apparatus includes: a blowing mechanism having an air-outlet channel for conveying dry gas to the material; a guide member movably arranged in the air-outlet channel and used for dividing the air-outlet channel into a first sub-air-outlet channel and a second sub-air-outlet channel, and a first air outlet of the first sub-air-outlet channel and a second air outlet of the second sub-air-outlet channel both facing the material.

By movably arranging the guide member in the air-outlet channel of the blowing mechanism, the guide member can divide the air-outlet channel into the first sub-air-outlet channel and the second sub-air-outlet channel when moving. The guide member does not change the area of a section of the air-outlet channel, and is only used for dividing the air-outlet channel into two sub-channels, therefore, a total air output of the drying apparatus does not change. Opening areas and internal volumes of the first sub-air-outlet channel and the second sub-air-outlet channel may be changed correspondingly with the movement of the guide member, and therefore, air speeds in the first sub-air-outlet channel and the second sub-air-outlet channel may be changed, thereby realizing adjustment of the air speed without changing the air volume. At the same time, the first air outlet of the first sub-air-outlet channel and the second air outlet of the second sub-air-outlet channel are both arranged to face the material, so that air flows from the air-outlet channel to the first sub-air-outlet channel and the second sub-air-outlet channel will eventually blow to the material, thereby fully ensuring the drying efficiency of the drying apparatus for the material.

A rotation shaft is rotationally arranged in the air-outlet channel, and the guide member is fixed on the rotation shaft. When rotating with the rotation shaft, the guide member changes air outputs of the first air outlet and the second air outlet. By rotationally arranging the rotation shaft in the air-outlet channel and fixing the guide member on the rotation shaft, convenient control of the guide member may be achieved by rotating the rotation shaft to adjust opening sizes of the first sub-air-outlet channel and the second sub-air-outlet channel, so that the air outputs of the first air outlet and the second air outlet may change inversely without changing the total air output, and corresponding adjustment may be performed according to actual requirements to achieve the best drying efficiency.

The blowing mechanism includes a first rotational connecting portion and a second rotational connecting portion arranged oppositely. The guide member is located between the first rotational connecting portion and the second rotational connecting portion, and the rotation shaft is rotationally connected to the first rotational connecting portion and the second rotational connecting portion. By arranging the guide member between the first rotational connecting portion and the second rotational connecting portion, and rotationally connecting the rotation shaft to the first rotational connecting portion and the second rotational connecting portion, the guide member can be smoothly fixed on the blowing mechanism when it rotates to a desired position.

A surface of the first rotational connecting portion protrudes to form a first arc-shaped protrusion, a surface of the second rotational connecting portion protrudes to form a second arc-shaped protrusion, the first arc-shaped protrusion and the second arc-shaped protrusion are arranged oppositely, and the rotation shaft is rotationally arranged on the first arc-shaped protrusion and the second arc-shaped protrusion respectively. The first arc-shaped protrusion and the second arc-shaped protrusion are arranged on the first rotational connecting portion and the second rotational connecting portion respectively, and the rotation shaft is arranged on the first arc-shaped protrusion and the second arc-shaped protrusion respectively, so that the rotation shaft and the guide member can be conveniently placed on the blowing mechanism or taken off from the blowing mechanism under the support of the first arc-shaped protrusion and the second arc-shaped protrusion, and the rotation shaft and the guide member can rotate smoothly for adjustment.

In an unclaimed arrangement, the first rotational connecting portion is provided with a first connecting hole, the second rotational connecting portion is provided with a second connecting hole, the first connecting hole and the second connecting hole are arranged oppositely, and the rotation shaft is rotationally arranged in the first connecting hole and the second connecting hole respectively. The first connecting hole and the second connecting hole are arranged on the first rotational connecting portion and the second rotational connecting portion respectively, and the rotation shaft is rotationally arranged in the first connecting hole and the second connecting hole respectively, so that the rotation shaft and the guide member are reliably connected to the blowing mechanism, thereby ensuring the stability of an overall structure of the drying apparatus.

In an optional manner, an outer cover of the second sub-air-outlet channel is provided with an air box, one side of the air box facing the material is provided with an opening, and the air box is used for accommodating the gas blown from the second sub-air-outlet channel, so that the gas is blown to the material from the opening. The air box is arranged on the outer cover of the second sub-air-outlet channel to accommodate the gas blown out of the second sub-air-outlet channel in the air box, and by arranging the opening on the side of the air box facing the material, the gas accommodated in the air box can be smoothly blown to the material through the opening, thereby ensuring the drying efficiency of the drying apparatus for the material.

In an optional manner, the opening is provided with a guide plate, and the guide plate is provided with meshes. By arranging the guide plate at the opening and arranging the mesh on the guide plate, the mesh can provide uniform dispersion and guidance for the gas in the air box. Specifically, the mesh evenly distributes the gas in the air box to different holes and guides the gas to blow to the material, so that the air flow on the material surface is more uniform, which is conducive to ensuring the uniformity of the drying degree of the material surface.

In an optional manner, one end of the rotation shaft is provided with an adjusting member. By arranging the adjusting member at one end of the rotation shaft, it is more convenient to control and adjust the guide member.

According to another aspect of the present application, an oven is provided, which includes the drying apparatus in any of the above methods. There are a plurality of drying apparatuses, and the plurality of drying apparatuses are arranged in a preset direction.

In the oven provided by the present application, by movably arranging the guide member in the air-outlet channel of the blowing mechanism, the guide member can divide the air-outlet channel into the first sub-air-outlet channel and the second sub-air-outlet channel when moving. The guide member does not change the area of a section of the air-outlet channel, and is only used for dividing the air-outlet channel into two sub-channels; therefore, a total air output of the drying apparatus does not change. Opening areas and internal volumes of the first sub-air-outlet channel and the second sub-air-outlet channel may be changed correspondingly with the movement of the guide member, and therefore, air speeds in the first sub-air-outlet channel and the second sub-air-outlet channel may be changed, thereby realizing adjustment of the air speed without changing the air volume. At the same time, the first air outlet of the first sub-air-outlet channel and the second air outlet of the second sub-air-outlet channel are both arranged to face the material, so that air flows from the air-outlet channel to the first sub-air-outlet channel and the second sub-air-outlet channel will eventually blow to the material, thereby fully ensuring the drying efficiency of the oven for the material.

In an optional manner, air boxes are arranged on both sides of the plurality of drying apparatuses in the preset direction, and the air boxes between adjacent drying apparatuses are in communication with each other. By arranging the air boxes on both sides of the plurality of drying apparatuses in the preset direction, and communicating the air boxes between adjacent drying apparatuses, a space occupied by an air box wall in the preset direction is eliminated, space occupation of the oven is effectively reduced, a structural layout of the oven is optimized, and full coverage of blowing in the preset direction is realized, which can fully improve the drying efficiency.

For drying apparatuses that perform drying by blowing air, areas of air outlets on some drying apparatuses are fixed, and the air speed or air volume cannot be adjusted adaptively, so the drying efficiency is low. Some drying apparatuses have wind shields in air flow channels. By moving the wind shield, the area of an air flow channel will be increased or decreased, thereby realizing the adjustment of the air speed and air volume. However, since the air volume will increase with the increase of the air speed and decrease with the decrease of the air speed, it is difficult to be adjusted to an appropriate position, thereby affecting the drying efficiency.

Based on this, a drying apparatus is proposed in the present application. By movably arranging a guide member in an air-outlet channel of a blowing mechanism, the guide member can divide the air-outlet channel into a first sub-air-outlet channel and a second sub-air-outlet channel when moving. The guide member does not change the area of a section of the air-outlet channel, and is only used for dividing the air-outlet channel into two sub-channels; therefore, a total air output of the drying apparatus does not change. Air speeds of the first sub-air-outlet channel and the second sub-air-outlet channel may be changed correspondingly with the movement of the guide member, thereby realizing adjustment of the air speed without changing the air volume, and ensuring the drying efficiency of the drying apparatus for the material.
