Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet cleaning technology, specifically to a silicon steel sheet cleaning device for stator cores. Background Technology

[0002] The stator core is a crucial component of the stator and a major part of the motor's magnetic circuit. It consists of parts such as sector-shaped plates, ventilation slots, positioning ribs, upper and lower toothed pressure plates, tension bolts, and support plates. The stator core is made by stamping silicon steel sheets into sector-shaped plates and stacking them onto the positioning ribs. The positioning ribs are welded to the frame ring plate via support plates, and the core is then pressed together into a single unit using upper and lower toothed pressure plates and tension bolts. The core also houses the windings. During generator operation, the core is subjected to a combination of mechanical, thermal, and electromagnetic forces. The silicon steel sheets used for the stator core need to be stamped into specified shapes on a punch press. After processing, the surface of the silicon steel sheets will retain waste debris and oil stains, requiring cleaning.

[0003] In existing technologies, the cleaning of silicon steel sheets mainly adopts the following methods: First, manual wiping, which is simple to operate but inefficient and the cleanliness is unstable; second, spray cleaning, which removes surface stains by spraying high-pressure water or cleaning agents, but there are dead corners in the cleaning and a large amount of water is consumed. Utility Model Content

[0004] The technical problem to be solved by this invention is that the cleaning efficiency of silicon steel sheets is low and the water consumption is high in the prior art.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A device for cleaning silicon steel sheets for stator cores includes a housing with several support legs fixedly connected to the lower end of the housing, a stirring mechanism and a circulation mechanism, a cleaning tank at the upper end of the housing, the stirring mechanism connected inside the housing to stir the silicon steel sheets in the cleaning tank, and the circulation mechanism connected outside the housing.

[0007] The circulation mechanism includes a circulation tank and a water pump. The tank has a collection tank, and a plurality of first through holes are provided between the collection tank and the cleaning tank.

One end of the water supply pipe is fixed to and connected to the lower end of the circulation tank, and the other end of the water supply pipe is fixed to the outside of the tank and connected to the cleaning tank. A drain pipe is fixed to the lower end of the circulation tank.

[0008] Furthermore, the stirring mechanism includes a motor and stirring plates. The motor is horizontally fixed to the outside of the housing, and a connecting shaft is fixed to the output end of the motor. The connecting shaft is horizontally rotatably connected to the cleaning tank, and the two stirring plates are symmetrically fixed to both sides of the connecting shaft.

[0009] Furthermore, the bottom of the inner wall of the cleaning tank is set as a semi-cylindrical surface, the stirring plate is rotated and attached to the lower inner wall of the cleaning tank, and the stirring plate is provided with several second through holes.

[0010] Furthermore, a discharge port is provided on one side of the box body, and a connecting block is inserted into the discharge port. One end of the connecting block is set as an arc surface and has the same curvature as the inner wall of the bottom of the cleaning tank. A first mounting plate is fixed to the other end of the connecting block. The first mounting plate is set as a U-shaped structure and is fixed to the box body by bolts. A first rubber sealing ring is fitted on the connecting block and fixed to the first mounting plate.

[0011] Furthermore, the bottom of the inner wall of the collection tank is inclined, and the circulation box is connected to the lower end of the bottom surface of the collection tank.

[0024] like Figure 1-6 As shown, a silicon steel sheet cleaning device for stator cores includes a housing 1, with several support legs 3 fixedly connected to the lower end of the housing 1, and also includes a stirring mechanism 2 and a circulation mechanism 4. A cleaning tank 101 is provided at the upper end of the housing 1. The stirring mechanism 2 is connected inside the housing 1 to stir the silicon steel sheets in the cleaning tank 101, and the circulation mechanism 4 is connected outside the housing 1.

[0025] like Figure 2-4 As shown, the stirring mechanism 2 includes a motor 201 and stirring plates 203. The motor 201 is horizontally fixed to the outside of the housing 1. A connecting shaft 202 is fixed to the output end of the motor 201. The connecting shaft 202 is horizontally rotatably connected to the cleaning tank 101. Two stirring plates 203 are symmetrically fixed to both sides of the connecting shaft 202. The bottom of the inner wall of the cleaning tank 101 is set as a semi-cylindrical surface. The stirring plates 203 are rotatably attached to the lower inner wall of the cleaning tank 101. Several second through holes 204 are provided on the stirring plates 203. A discharge port 104 is opened on one side of the housing 1. A connecting block 501 is inserted into the discharge port 104. The end of the connecting block 501 is set as an arc surface and has the same curvature as the inner wall of the bottom of the cleaning tank 101. The other end of the connecting block 501 is fixedly connected to a first mounting plate 5. The first mounting plate 5 is set as a U-shaped structure and is fixed to the box 1 by bolts. The connecting block 501 is fitted with a first rubber sealing ring 502 fixed to the first mounting plate 5. The stirring plate 203 is driven by the motor 201 to rotate, thereby causing the silicon steel sheet to rotate in the water in the cleaning tank 101. The water flows relative to the surface of the silicon steel sheet, washing away the surface impurities. After cleaning, the connecting block 501 is taken out from the discharge port 104. The stirring plate 203 is rotated to push the silicon steel sheet out from the discharge port 104, so that it can be collected from the discharge port 104.

[0026] like Figure 5 , 6As shown, the circulation mechanism 4 includes a circulation tank 401 and a water pump 402. A collection tank 102 is provided in the tank body 1. Several first through holes 103 are provided between the collection tank 102 and the cleaning tank 101. The circulation tank 401 is fixed to the lower end of the tank body 1 and connected to the lower end of the collection tank 102. A drain pipe 408 is fixed to the lower end of the circulation tank 401. The water pump 402 is fixed to the outside of the tank body 1 and connected to a water supply pipe 403. One end of the water supply pipe 403 is fixed to and connected to the lower end of the circulation tank 401, and the other end is fixed to the outside of the tank body 1 and connected to the cleaning tank 101. The bottom of the inner wall of the collection tank 102 is inclined. The circulation tank 401 is connected to the collection tank. At the lower end of the bottom surface of 102, a filter box 404 is connected to the circulation box 401. The bottom of the filter box 404 is provided with horizontally distributed filter screens 405. A second mounting plate 406 is fixedly connected to one end of the filter box 404. The second mounting plate 406 is designed with a U-shaped structure. A second rubber sealing ring 407 is fixedly connected to the inner side of the second mounting plate 406 and sleeved on the filter box 404. When cleaning the silicon steel sheet, the water pump 402 drives the water in the cleaning tank 101 to circulate through the circulation mechanism 4, which promotes the flow of water in the cleaning tank 101 to clean the silicon steel sheet. The water can filter and collect the cleaned metal debris during circulation, so that the cleaning water can be recycled multiple times and reduce water consumption.

[0027] In use, the silicon steel sheet is placed in the cleaning tank 101 and clean water is added to cover it. The water pump 402 is turned on, and the water in the cleaning tank 101 enters the collection tank 102 through the first through hole 103. Then, it enters the filter box 404 in the circulation box 401 along the inclined bottom surface of the collection tank 102. After the metal debris is filtered by the filter screen 405, it enters the water supply pipe 403. Driven by the water pump 402, the water is returned to the cleaning tank 101 through the water supply pipe 403, so that the water continues to circulate and keep flowing to clean the silicon steel sheet. At the same time, the output end of the motor 201 drives the connecting shaft 202 to rotate, which in turn drives the stirring plate 203 to rotate, thereby stirring the silicon steel sheet and further promoting the flow of water on the surface of the silicon steel sheet to achieve cleaning.

[0028] After the silicon steel sheets are cleaned, the control valve on the drain pipe 408 is opened to discharge the cleaning water. The connecting block 501 is pulled away from the discharge port 104 through the first mounting bracket. Under the push of the stirring plate 203, the silicon steel sheets are discharged from the discharge port 104 and collected. Then, the filter box 404 is disassembled from the circulation box 401 using the second mounting plate 406 to clean the filtered metal debris.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
