Also disclosed is a method for freezing the aquatic products by using the apparatus.
B: Disclosed in the present utility model is a water surface rubbish cleaning machine, comprising a support frame, a mounting plate being fixedly arranged at the upper end of the support frame, a floating airbag being arranged at one end of the mounting plate, two support crossbars being arranged on the inner side of the support frame, a support framework being arranged on the upper end of the support crossbars, a fishing net being arranged on the inner side of the support framework, a drive motor being fixedly mounted on both sides of one end of the inner side wall of the support frame, a rotating shaft being fixedly connected to an output shaft of the drive motors, a gear being fixedly arranged on the rotating shaft, a rack being fixedly arranged on the sides of the support crossbars furthest from one another, a collecting tank being fixedly arranged on the left and right sides of the upper end of the support frame, a feed inlet being arranged on the upper end of the sides of the two collecting tanks closest to one another, and a filter mesh being arranged inside the collecting tanks. The present utility model facilitates cleaning and collection of water surface rubbish, and can increase water surface rubbish cleaning efficiency and save labour.
C: An auto-adding dye mechanism for intelligent manufacturing production and dyeing of a garment fabric, comprising a main body. Supporting springs are arranged at the bottom of an inner wall of the main body, supporting rods are fixedly mounted at the upper ends of the supporting springs, and dye boxes are fixedly mounted on the upper ends of the supporting rods, first gear racks being arranged on the sides of the supporting rods facing away from each other, movable gears are connected to the outer sides of the first gear racks by means of meshing, second gear racks are connected to the sides of the gears away from the first gear strips by means of meshing, and movable blocks are fixedly installed on the sides of the second gear racks away from the movable gears. In the present auto-adding dye mechanism for intelligent manufacturing production and dyeing of garment fabric, after dyeing is finished, a garment fabric above a screen is driven to move upwards by means of driving the sliding blocks, and then kinetic energy is generated by means of a drying mechanism to perform drying processing on the dyed garment fabric, thus allowing for rapid drying, convenient use, and a high working efficiency, and having value for broad use.
D: An efficient drying device for a panel, comprising a drying device body (1). Feed inlets (3) are fixedly connected to the front of the drying device body (1). Block panels (5) are fixedly connected to both left and right sides of the feed inlets (3). Nuts (4) are fixedly connected to left and right sides on the front of the block panels (5). A controller (2) is fixedly connected to the upper left side on the front of the drying device body (1). A base (6) is fixedly connected to the bottom of the drying device body (1). Support rods (11) are fixedly connected to the bottom on the left side of the drying device body (1). Fixing blocks (8) are fixedly connected to the front of the support rods (11). The drying device body (1), the block panels (5), the feed inlets (3), and the nuts (4) work in conjunction to dry panels while keeping the drying positions uniform.
