DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention.

FIG.1toFIG.10show a rotary kiln with a stirring function, including: a kiln head, a roller1and a kiln tail. The roller1is obliquely arranged on the kiln head and the kiln tail. The rotary kiln further includes a mounting shaft3and stirring mechanisms4. Linkage elements2are arranged on an inner wall of the roller1, and the linkage elements2are configured to drive the stirring mechanisms4to perform a stirring operation. Each of the stirring mechanisms4includes a rotating ring sleeve41and two limiting slide bases42, the rotating ring sleeve41is provided with three telescopic frame bodies43arranged at equal angles, a telescopic baffle44in slide fit with each of the telescopic frame bodies43is arranged in each of the telescopic frame bodies43, the telescopic baffle44can abut against and cooperate with the linkage element2after extending out, a mounting groove441is formed in the telescopic baffle44, a secondary propulsion assembly5is arranged in the mounting groove441, the secondary propulsion assembly5is configured to accelerate the telescopic speed of the telescopic baffle44, a detachable sealing cover442is arranged at an inner end of the telescopic baffle44, the sealing cover442is configured to seal the mounting groove441, the telescopic frame body43is communicated with the rotating ring sleeve41, and the two limiting slide bases42are arranged on the mounting shaft3at an interval; and a pop-up assembly6configured to prevent the telescopic baffle44from being stuck is arranged on a lower right side wall of the mounting shaft3, the mounting shaft3is mounted on the kiln head and the kiln tail, the mounting shaft3is coaxial with the roller1, the stirring mechanisms4are rotatably arranged on the mounting shaft3, and the stirring mechanisms4are located between the two limiting slide bases42. After the roller1rotates, the linkage element2is driven to rotate synchronously, until the linkage element2is in contact with the telescopic baffle44extending from the telescopic frame body43, then the linkage element2can drive the entire rotating ring sleeve41to synchronously rotate together, the telescopic baffle44and the telescopic frame body43cooperate to scoop up part of the hazardous wastes in the roller1, this part of the hazardous wastes will naturally scatter after reaching a high place, the telescopic baffle44gradually retracts into the telescopic frame body43due to the action of gravity after reaching a high place, and then, the linkage element2is separated from the telescopic baffle44; when the linkage element2is in contact with the next extended telescopic baffle44, the entire rotating ring sleeve41can be driven to rotate by a certain angle; during rotation, part of the hazardous wastes is scooped up and stirred, and the retraction and extension speed of the telescopic baffle44can be accelerated through the secondary propulsion assembly5; during extension, an additional impact force can also be provided, so that the telescopic baffle44can be better inserted into the hazardous wastes and is in contact with the inner wall of the roller1; and when the telescopic baffle44rotates to a lower right position around the mounting shaft3, if the telescopic baffle44can not perform an action of extending out due to gravity because of excessive sticking, the pop-up assembly6can provide an ejection force for the telescopic baffle44, so that the telescopic baffle44can perform the action of extending out.

In a specific implementation, a plurality of stirring mechanisms4are provided, and all stirring mechanisms4are rotatably arranged on the mounting shaft3at equal intervals in a direction from the kiln tail to the kiln head. An appropriate number of stirring mechanisms4are selected according to the length of the roller1.

Preferably, the hazardous wastes are all stacked at the rear section of the roller1, so that the stirring mechanisms4are arranged at the rear section of the roller1, and then, the stirring effect is better.

In a specific implementation, the secondary propulsion assembly5includes two guide rods51and a propulsion block52, a threaded hole511is formed in a top of each of the guide rods51, a bolt512matched with the threaded hole511is arranged in the threaded hole511, the propulsion block52is provided with two guide chutes in guide fit with the guide rods51, the two guide rods51are symmetrically arranged in the mounting groove441, the propulsion block52is slidably arranged on the two guide rods51through the two guide chutes, and the sealing cover442is provided with two counter bores4421matched with the bolts512. When the telescopic baffle44gradually rotates to a low place around an axis of the rotating ring sleeve41, the propulsion block52will also move on the two guide rods51due to self-gravity, the propulsion block52can impact a groove wall of the mounting groove441of the telescopic baffle44after moving, and the impact force can be transferred to the telescopic baffle44, so that the extension speed of the telescopic baffle44is accelerated. In a similar way, the retraction speed of the telescopic baffle44can be accelerated.

In a specific implementation, an inclined surface443is arranged at an outer end of the telescopic baffle44. In this way, the outer end of the telescopic baffle44forms a pointed end, so that the telescopic baffle44can be conveniently inserted into the hazardous wastes.

In a specific implementation, a plurality of scraping strips444arranged at equal intervals are also arranged at the outer end of the telescopic baffle44. The scraping strips444can be configured to scrape off the hazardous wastes adhering to an inner bottom wall of the roller1.

In a specific implementation, two linkage elements2are provided, the two linkage elements2are arranged on the inner wall of the roller1at equal angles, and each of the linkage elements2is provided with a wedge surface21matched with the inclined surface443. The two linkage elements2can reduce the down time of the rotating ring sleeve41, so that the stirring efficiency is higher. The inclined surface443is matched with the wedge surface21to provide additional power for the telescopic baffle44when retracting into the telescopic frame body43, so that the telescopic baffle44can retract more quickly.

In a specific implementation, the linkage element2is Z-shaped. As shown inFIG.1andFIG.9, the Z-shaped linkage element2and the inner wall of the roller1can form a containing groove7, and the containing groove7can also carry part of the hazardous wastes to rotate with the roller1to realize a stirring operation, thereby improving the stirring effect.

In a specific implementation, the pop-up assembly6includes a pop-up housing61and a plurality of return springs62, an opening611is formed in one end of the pop-up housing61, limiting blocks612are arranged on both sides of the opening611, an arc surface613is arranged at the other end of the pop-up housing61, a built-in groove31matched with the pop-up housing61is formed on the lower right side wall of the mounting shaft3, detachable stop blocks311configured to stop the limiting blocks612are arranged on both sides of the built-in groove31, the pop-up housing61and all return springs62are arranged in the built-in groove31, the pop-up housing61is sleeved on all return springs62, and one end of each of the return springs62is in contact with an inner side wall of the pop-up housing61. When the telescopic frame body43gradually rotates to the pop-up housing61, the pop-up housing61can be quickly ejected from the built-in groove31through the elasticity of the return springs62, the pop-up housing61can perform an impact on the inner end of the stuck telescopic baffle44, and the impact enables the telescopic baffle44to extend out from the telescopic frame body43. The deflection of the movement of the pop-up housing61can be avoided through the limiting block612, the pop-up distance of the pop-up housing61can be limited through the stop block311, then the rotating ring sleeve41continues to rotate, the pop-up housing61can retract into the built-in groove31through the contact of the arc surface613of the pop-up housing61, and the return spring62returns to a compressed state.
