[0027] Based on this, the inventors created a cleaning device for the screen of a lithium iron phosphate sand mill, as described in this application, to solve the above-mentioned technical problems.

[0028] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] Please see Figure 1A cleaning device for a lithium iron phosphate sand mill screen includes a frame 10, a lifting assembly 20, a rotating assembly 30, a switching assembly 40, a water supply assembly 50, and a control assembly 60. The lifting assembly 20 is inverted and mounted on the frame 10, and is adapted to drive the rotating assembly 30 to move up and down. The driving end of the rotating assembly 30 is provided with a mounting block 31 suitable for mounting the screen 70. For example, the lifting assembly 20 can be a hydraulic cylinder, a pneumatic cylinder, etc., and this invention is not limited thereto. For example, the rotating assembly 30 can be a motor.

[0031] The switching component 40 is configured to switch different water buckets 41 to the area below the screen 70, and the water supply component 50 is configured to supply water to the water buckets 41. For example, the switching component 40 can be linearly driven or rotary driven, and the path of the water buckets 41 being switched is not limited. For example, the water supply component 50 can be a tap water pipe.

[0032] The control component 60 includes a level monitor 61, a first electrically controlled valve 62, a second electrically controlled valve 63, and a controller 64. The level monitor 61 is adapted to monitor the level of the water tank 41. The first electrically controlled valve 62 is located at the outlet of the water tank 41, and the second electrically controlled valve 63 is located at the outlet of the water supply component 50. The input terminal of the controller 64 is connected to the level monitor 61, and the output terminal of the controller 64 is connected to the first electrically controlled valve 62 and the second electrically controlled valve 63. Here, the level monitor 61 can be a level gauge. The required liquid level for releasing debris can be determined based on production practice. Once determined, it is monitored by the level monitor 61, and the first electrically controlled valve 62 executes the release. The liquid level discharged by the first electrically controlled valve 62 is replenished by the second electrically controlled valve 63 in the same amount.

[0033] The cleaning device of this utility model includes a frame 10, a lifting component 20, a rotating component 30, a switching component 40, a water supply component 50, and a control component 60. When cleaning the screen 70, the rotating component 30 drives the screen 70 to rotate, and the lifting component 20 lowers the entire screen 70 into the water bucket 41 to achieve cleaning of the screen 70. After cleaning a large number of screens 70, the switching component 40 switches to a new water bucket 41 below the screen 70. In the water bucket 41, which has a lot of debris, the debris sinks during the settling process. The level gauge monitors the level of the water bucket 41, and the controller 64 discharges the debris to a preset level through the first solenoid valve 62 and inputs a preset level through the second solenoid valve 63, so that the water in the water bucket 41 remains basically unchanged. Then, the water bucket 41 can be switched again to clean the screen 70. This application solves the problems of cumbersome operation and low cleaning efficiency of existing cleaning equipment.

[0034] In another embodiment, the switching component 40 includes a turntable with a plurality of water buckets 41 evenly arranged around its central axis.

[0035] In another embodiment, the cleaning device further includes a conveying assembly adapted to deliver flocculant to the water tank 41. This configuration, by adding flocculant to the water tank 41 via the conveying assembly, enables faster sedimentation and improves efficiency.

[0036] In another embodiment, the frame 10 is equipped with a photoelectric gate transmitter, and the turntable is equipped with a corresponding photoelectric gate receiver for each of the water buckets 41. When the transmitter is aligned with the receiver, the screen 70 is aligned with one of the water buckets 41. This arrangement ensures that the screen 70 is aligned with the water bucket 41, preventing damage to the screen 70 due to misalignment. Preferably, the photoelectric gate is connected to the controller 64, and the output of the controller 64 is connected to the lifting assembly 20. This arrangement allows the controller 64 to stop the lifting assembly 20 from lifting when misaligned, preventing accidents.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
