[0027] a cleaning mechanism 30, the cleaning mechanism 30 comprises a rotating motor 31, the output shaft of the rotating motor 31 is fixedly connected with an adjusting screw 311, the adjusting screw 311 is threadedly connected with the center of a filter plate 32, the outer side of the filter plate 32 is rotatably connected with the inner side of a cleaning plate 33, and the cleaning plate 33 is slidably connected with the stirring roller 23.
[0028] In the embodiment, it should be noted that the device is used in cooperation with a controller (not shown in the figure), the controller is electrically connected with the driving motor 21 and the rotating motor 31 respectively, and effectively controls the opening and closing of the above-mentioned motors. This is a conventional technical means, and will not be described in detail here. Specifically, the stirring mechanism 20 can effectively drive the stirring roller 23 to stir the waste residue and the reaction liquid inside the reaction kettle 10, promoting the dissolution of the waste residue. At the same time, through the cooperation of the stirring roller 23 and the cleaning mechanism 30, the cleaning plate 33 can effectively clean the inner wall of the reaction kettle 10, ensuring that the waste residue attached to the inner wall is effectively removed, and at the same time, the aluminum liquid can be effectively prevented from condensing on the inner wall of the reaction kettle 10. Through the setting of the filter plate 32, the solid and liquid generated during the stirring reaction can be effectively separated, ensuring that they can be treated separately and improving the recycling efficiency.
[0029] Preferably, the inner side of the driving ring 22 is provided with a driving tooth groove, and the driving gear 211 is connected with the driving tooth groove in meshing connection. Through the meshing action of the driving gear 211 and the driving tooth groove, the driving ring 22 and the stirring roller 23 are driven to rotate in the reaction kettle 10, thereby completing the stirring of the reaction liquid.
[0030] As shown in Figure 2 , Figure 4 , the outer side of the filter plate 32 is fixed with a limiting lug, and the limiting lug is connected with the limiting groove provided in the inner side of the cleaning plate 33 in sliding connection. Specifically, through the action of the limiting lug and the limiting groove, when the filter plate 32 is driven to lift by the rotating motor 31, the cleaning plate 33 can be synchronously lifted to ensure the cleaning of the inner wall of the reaction kettle 10.
[0031] As shown in Figure 3 , a plurality of sliding holes are provided on the cleaning plate 33, and a plurality of stirring rollers 23 are connected with the plurality of sliding holes in sliding connection. In addition, a plurality of cleaning scrapers 331 are fixed on the upper side of the outer side of the cleaning plate 33, and the plurality of cleaning scrapers 331 are connected with the inside of the reaction kettle 10 in rotation connection, which can effectively scrape off the impurities on the inner wall of the reaction kettle 10.
[0032] Preferably, the material of the cleaning scraper 331 is one of rubber or polytetrafluoroethylene, which has corrosion resistance and can improve the service life of the cleaning scraper 331.

[0034] In this embodiment, it should be noted that when the rotating motor 31 is driven to rotate by the driving ring 22, the adjusting screw 311 will not rotate with the rotation of the rotating motor 31, and thus will not threadedly act with the filter plate 32, ensuring that the filter plate 32 can be stably positioned at the bottom of the reaction kettle 10. When it is necessary to adjust the position of the filter plate 32 and the cleaning plate 33, the rotating motor 31 is controlled to drive the adjusting screw 311 to threadedly act with the filter plate 32, thereby driving the filter plate 32 to lift in the reaction kettle 10. At the same time, the outer side of the filter plate 32 is connected with the cleaning plate 33 in rotation connection, which can synchronously drive the cleaning plate 33 to lift. At the same time, the cleaning plate 33 will scrape off the impurities on the inner wall of the reaction kettle 10 through the action of the stirring roller 23.
[0035] Preferably, the outer side of the reaction kettle 10 is provided with a feeding port, and the bottom of the reaction kettle 10 is provided with a liquid outlet; wherein the feeding port is hinged with a protective door, and the liquid outlet is fixed with a control valve, which can effectively control the outflow of the reaction liquid.
[0036] The working principle of the utility model is as follows: when the waste residue recovery reaction is needed, the waste residue and the reaction liquid are put into the inside of the reaction kettle 10, then the driving motor 21 is controlled to rotate, the driving ring 22 is driven to rotate in the rotating groove 11 in the inside of the reaction kettle 10 through the meshing action of the driving gear 211, and the plurality of stirring rollers 23 fixed at the bottom are driven to stir the reaction liquid and the waste residue, at the same time, the cleaning plate 33 is driven to rotate in the inside of the reaction kettle 10 through the bottom of the stirring roller 23, so as to clean the inner wall of the reaction kettle 10; wherein the rotating motor 31 is fixedly connected with the bottom of the driving ring 22 through the connecting plate 312, when the rotating motor 31 rotates, the adjusting screw 311 will rotate with the rotating motor 31, at this time, the filter plate 32 will not threadedly act with the adjusting screw 311; when the reaction substance in the inside of the reaction kettle 10 needs to be solid-liquid separated, the rotating motor 31 is driven to drive the adjusting screw 311 to threadedly act with the center of the filter plate 32, and then the filter plate 32 is driven to ascend and descend in the inside of the reaction kettle 10, so as to separate the solid and the liquid generated by the stirring reaction; at the same time, when the filter plate 32 ascends and descends, the cleaning plate 33 rotationally connected with the outside of the filter plate 32 can be synchronously driven to ascend and descend, through the driving of the stirring roller 23, the inside of the reaction kettle 10 can be cleaned in all directions, so as to ensure that the impurities attached to the inner wall are effectively removed.
[0037] The above only describes the preferred embodiments of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
