[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5A waste liquid treatment and recovery device shown in the figure includes a recovery cylinder 1, and a feed hole and a discharge hole are opened on the inner wall of the peripheral side of the recovery cylinder 1. A feed pipe and a discharge pipe are sealed in the feed hole and the discharge hole respectively, and a discharge valve is arranged on the discharge pipe. A stirring shaft 2 is rotatably installed on the inner wall of the top of the recovery cylinder 1, and a plurality of mixing blades 3 are evenly arranged on the stirring shaft 2. A stirring motor 4 is fixedly installed on the top of the recovery cylinder 1, and the output shaft of the stirring motor 4 is fixedly connected to the top of the stirring shaft 2. A rotating plate 5 is rotatably sleeved on the stirring shaft 2, and a cleaning shaft 7 is rotatably installed on the bottom of the rotating plate 5, a cleaning roller brush 10 is fixedly sleeved on the cleaning shaft 7, and a self-rotation component is arranged on the cleaning shaft 7, a square plate 11 is fixedly sleeved on the stirring shaft 2, and two extrusion plates 12 are slidably installed in the rotating plate 5 through a sliding component, and the two extrusion plates 12 are both adapted to the square plate 11.

[0024] With the above structure, when in use, first pour the waste liquid into the recovery barrel 1 through the feed pipe, then drive the stirring shaft 2 and multiple mixing blades 3 to rotate synchronously through the stirring motor 4 to mix the waste liquid in the recovery barrel 1, and discharge it through the discharge pipe after the waste liquid is neutralized. When it is necessary to clean the inside, add cleaning liquid to the recovery barrel 1, and then drive the two extrusion plates 12 to move synchronously toward each other through the sliding component to squeeze the square plate 11, and then start the driving motor 4 to drive the stirring shaft 2 and the square plate 11 to rotate synchronously, and drive the two extrusion plates 12, the rotating plate 5, and the cleaning shaft 7 to rotate synchronously through the square plate 11, and cooperate with the self-rotating component to drive the cleaning shaft 7 and the cleaning roller brush 10 to rotate synchronously to clean the inner wall of the peripheral side of the recovery barrel 1.

[0025] like Figure 5 As shown, a limiting circular groove is provided on the circumferential inner wall of the recovery cylinder 1, and two arc-shaped limiting strips 6 are slidably installed in the limiting circular groove. The circumferential inner walls of the two arc-shaped limiting strips 6 are fixedly connected to the circumferential outer wall of the rotating plate 5. The advantage of such an arrangement is that the limiting function of the rotating plate 5 can be realized through the arrangement of the limiting circular groove and the two arc-shaped limiting strips 6.

[0026] Specifically, by fixedly connecting the two arc-shaped limiting strips 6 to the rotating plate 5 , the rotating plate 5 can be limited by the arc-shaped limiting strips 6 to prevent it from falling off, thereby improving stability during use.

[0027] like Figure 2 As shown, the self-rotating assembly includes a self-rotating gear 8 and an annular rack 9. The self-rotating gear 8 is fixedly sleeved on the cleaning shaft 7, and the annular rack 9 is fixedly installed on the circumferential inner wall of the recovery barrel 1. The self-rotating gear 8 is meshed with the annular rack 9. The advantage of such an arrangement is that, through the arrangement of the self-rotating gear 8 and the annular rack 9, the revolution of the self-rotating gear 8 can drive it to mesh with the annular rack 9, thereby driving it to rotate.

[0028] Specifically, when the rotating plate 5 rotates, it drives the cleaning shaft 7 and the rotating gear 8 to rotate, and then through the meshing action of the rotating gear 8 and the annular rack 9, it drives them to rotate, and then drives the cleaning shaft 7 and the cleaning roller brush 10 to rotate synchronously to clean the inner wall of the peripheral side of the recovery cylinder 1.

[0029] like Figure 4 As shown, the sliding assembly includes two bidirectional screw rods 13, both ends of which are rotatably mounted on the opposite inner walls of the rotating plate 5, and the two bidirectional screw rods 13 are connected by a transmission unit. The two extrusion plates 12 are both threadedly mounted on the two bidirectional screw rods 13, and a driving unit is arranged at the end of one of the bidirectional screw rods 13. The advantage of such an arrangement is that through the arrangement of the two bidirectional screw rods 13, the two extrusion plates 12 can be driven to move toward or away from each other synchronously.

[0030] Specifically, the two bidirectional screw rods 13 are rotated to drive the two extrusion plates 12 to move toward each other synchronously, thereby extruding the square plate 11, so that when the square plate 11 rotates, the two extrusion plates 12 and the rotating plate 5 are driven to rotate synchronously.

[0031] like Figure 4 As shown, the transmission unit includes two sprockets 14, which are fixedly sleeved on two bidirectional screw rods 13 respectively, and a chain 15 is installed on the two sprockets 14 in meshing relationship. The advantage of such an arrangement is that the two bidirectional screw rods 13 can be driven to rotate synchronously through the arrangement of the two sprockets 14 and the chain 15.

[0032] Specifically, when one of the two-way screw rods 13 rotates, it drives one of the sprocket wheels 14 to rotate synchronously, and then drives the other two-way screw rod 14 to rotate synchronously through the meshing action of the sprocket wheel 14 and the chain 15, thereby preventing the extrusion plate 12 from getting stuck during horizontal movement.

[0033] like Figure 5 As shown, the driving unit includes a driving motor 16, a motor slot is opened on the inner wall of the side of the rotating plate 5, the driving motor 16 is fixedly installed in the motor slot, the output shaft of the driving motor 16 is connected to the end of one of the bidirectional screw rods 13, and a battery 17 is arranged on the top of the rotating plate 5, and the battery 17 is electrically connected to the driving motor 16. The advantage of such an arrangement is that the driving motor 16 can be powered by the arrangement of the battery 17, thereby preventing the rotating plate 5 from causing wire entanglement when rotating.

[0034] Specifically, by using the storage battery 17 to power the driving motor 16, it is possible to effectively avoid the phenomenon of wire entanglement when the rotating plate 5 rotates, and the protection is high.

[0035] like Figure 1As shown, a liquid level gauge 18 is provided on the peripheral outer wall of the recovery tube 1 . The advantage of such a setting is that the liquid level height in the recovery tube 1 can be observed through the setting of the liquid level gauge 18 .

[0036] Specifically, by providing the liquid level meter 18 , it is convenient for the staff to observe the liquid level height in the recovery tube 1 , so as to prevent the excessively high liquid level from affecting the components in the recovery tube 1 .

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
