[0028] Example

[0029] See also Figure 1 , Figure 2, a screw conveyor with a cleaning function, comprising a cylinder 10 and a spiral blade 20 coaxially arranged in the cylinder 10. Here, the spiral blade 20, driven by a power source (such as a motor 40), transfers the raw materials of the lithium iron phosphate battery from one end to the other end, and realizes quantitative acquisition of the raw materials. The side wall of the cylinder 10 is provided with an opening 11 along its length direction, and the opening 11 is detachably mounted with a long plate 12, and the inner side of the long plate 12 is provided with a plurality of nozzles 121 spaced along its length direction, and the plurality of the nozzles 121 are connected to each other, and the outer side of the long plate 12 is provided with a joint 122 connected to the nozzles 121. For example, the nozzle 121 is embedded in the inner wall of the long plate 12 so as not to affect the operation of the spiral blade 20. For example, a sealing strip can be provided between the long plate 12 and the cylinder 10 to improve the sealing performance and avoid leakage. For example, the long plate 12 is located at the top center of the cylinder 10 and covers the total length of the spiral blades 20, so that the sweeping brush 14 can clean all the spiral blades 20. A guide rail 13 parallel to the opening 11 is arranged outside the opening 11, and a sweeping brush 14 is slidably arranged on the guide rail 13. The sweeping brush 14 can extend into the opening 11 and abut against the rotating shaft 30 of the spiral blade 20.

[0030] In the screw conveyor of the utility model, an opening 11 and a long plate 12 are provided on the side wall of the cylinder 10. When it is necessary to clean the inside of the screw conveyor, the long plate 12 is removed, the screw conveyor is started and rotated slowly, the sweeping brush 14 is extended into the opening 11 and pressed against the surface of the rotating shaft 30 and the spiral blade 20, the sweeping brush 14 is moved along the guide rail 13, so that the sweeping brush 14 always moves along the surface of the spiral blade 20, and the rotating shaft 30 and the spiral blade 20 are cleaned. After cleaning, the long plate 12 is installed, high-pressure water is connected from the joint 122, and the spiral blade 20 and the rotating shaft 30 are washed with high-pressure water through the nozzle 121, so as to realize efficient cleaning of the inside of the screw conveyor.

[0031] In another embodiment, the sweeping brush 14 is parallel to the rotating shaft 30, so that when the spiral blade 20 rotates, the spiral blade 20 and the rotating shaft 30 can be cleaned by moving the sweeping brush 14. Preferably, the length of the sweeping brush 14 is 0.9-1.2 times the pitch of the spiral blade 20, so that the length of the sweeping brush 14 can basically cover one pitch, and the cleaning is faster and more thorough.

[0032] In another embodiment, the sweeping brush 14 is connected to a linear drive mechanism that drives it to slide along the guide rail 13. Preferably, the linear drive mechanism includes a cylinder, a hydraulic cylinder or a ball screw drive mechanism. Preferably, the linear drive mechanism is a ball screw drive mechanism, the screw of the ball screw drive mechanism is connected to the power source of the screw conveyor through a transmission component, and the moving speed of the sweeping brush 14 is matched with the forward conveying speed of the screw conveyor, that is, under a certain rotation speed of the power source, the forward conveying speed of the screw conveyor is substantially the same as the moving speed of the sweeping brush 14, so that the sweeping brush 14 can achieve relatively thorough cleaning with a single forward movement, and the cleaning efficiency is high.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made by any technician familiar with the field within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
