Description

Technical Field

[0001] This utility model relates to the field of DC motor processing, and in particular to a rust removal device for processing DC motor parts. Background Technology

[0002] Common rust removal methods include physical rust removal, mechanical rust removal, and chemical rust removal. Physical rust removal is usually used for light rust or localized rust; mechanical rust removal is usually used for more severe rust or larger areas; and chemical rust removal is usually used for stubborn rust. Chemical rust removal refers to removing rust by reacting it with an acidic solution or by using a rust remover.

[0003] A search of Chinese Patent Publication No. CN220413530U reveals a chemical rust removal device for mechanical parts. This device utilizes a rotating mechanism and transmission components to drive a rotating roller, a drive gear, and a cleaning brush ring to rotate inside a housing. The drive gear propels the mechanical parts to move below the liquid surface within the housing, creating a flipping effect. This allows for chemical rust removal, while the cleaning brush ring further cleans the rust from the parts' surface, resulting in dynamic rust removal. This ensures that rust adhering to the parts' surface is removed immediately, improving the overall efficiency of the rust removal process, shortening the removal time, and meeting user needs.

[0004] After a period of use, the rust removal solution may contain a lot of debris, which may affect the contact area between the solution and the motor parts, thus affecting the rust removal effect. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a rust removal device for processing DC motor parts includes a base 1, a rust removal cylinder 2 fixedly connected to the top of the base 1, a discharge pipe 201 fixedly connected to one side of the rust removal cylinder 2, and a solenoid valve installed in the discharge pipe 201 to facilitate the discharge of the solution in the rust removal cylinder 2.

[0026] A holding basket 306 is installed above the rust removal cylinder 2 via a lifting assembly. The front side of the holding basket 306 is hinged with an opening and closing door. The lifting assembly includes a frame 301 fixedly connected to the side wall of the rust removal cylinder 2. The frame 301 is U-shaped with the opening facing downwards. Two vertical plates 302 are bolted to the top of the frame 301. One side of one of the vertical plates 302 is bolted to a winding motor 303. The winding motor 303 is a brake motor. The output end of the winding motor 303 is connected to a spool 304 via a coupling. A rope 305 is wound on the spool 304. The bottom end of the rope 305 passes through the frame 301 and is fixedly connected to the holding basket 306. A through hole is opened at the top of the frame 301, and the rope 305 passes through the through hole.

[0027] An auxiliary mechanism is provided on one side of the rust removal cylinder 2. The auxiliary mechanism includes a filter box 401 fixedly connected to the top of the base 1. A connecting pipe 402 is fixedly connected between the filter box 401 and the rust removal cylinder 2. A solenoid valve is installed in the connecting pipe 402. A box cover 405 is inserted into the top of the filter box 401. A handle 4051 is fixedly connected to the top of the box cover 405.

[0028] The filter box 401 is equipped with a filter assembly, which includes a filter plate 5 fixedly connected to the bottom of the box cover 405. The filter plate 5 is L-shaped. The bottom wall of the filter box 401 has a groove. The bottom of the filter plate 5 is placed in the groove. The horizontal part of the filter plate 5 is located on the side close to the connecting pipe 402. A sealing plug 6 is fixedly connected to the bottom of the box cover 405. A through hole is opened in the middle of the sealing plug 6. The filter plate 5 passes through the through hole and extends out of the sealing plug 6.

[0029] A suction assembly is provided on the side of the filter box 401 away from the rust removal cylinder 2. The suction assembly is used to draw the solution in the rust removal cylinder 2 into the filter box 401 for filtration and then discharge it back into the rust removal cylinder 2. The suction assembly includes a water pump 403, which is bolted to the side of the filter box 401 away from the rust removal cylinder 2. The outlet of the water pump 403 is fixedly connected to a delivery pipe 404. The other end of the delivery pipe 404 is fixedly connected to an annular flow pipe 406. A one-way valve is provided in the delivery pipe 404 to prevent the solution in the rust removal cylinder 2 from flowing back. The annular flow pipe 406 is fixedly connected to the outer wall of the rust removal cylinder 2. Several outlet pipes 407 communicating with the annular flow pipe 406 are fixedly connected to the inner wall of the rust removal cylinder 2. The outlet pipes 407 are arranged radially inclined relative to the annular flow pipe 406.

[0030] Working Principle: During use, place the DC motor parts requiring rust removal into the holding basket 306. Start the winding motor 303, which drives the reel 304 to rotate, releasing the rope 305. The holding basket 306 is then inserted into the rust removal cylinder 2. Start the water pump 403, drawing the solution from the bottom of the rust removal cylinder 2 into the filter box 401 via the connecting pipe 402. The solution is filtered through the filter plate 5 to remove debris. The filtered solution is then transported through the conveying pipe 404 to the annular flow pipe 406, and then back into the rust removal cylinder 2 through several outlet pipes 407, achieving continuous circulation and real-time filtration of the solution. This process collects and filters out debris, preventing excessive debris from affecting the contact area between the solution and the motor parts, thus ensuring optimal performance. For rust removal, the outlet pipe 407 is tilted, causing the sprayed solution to form a vortex inside the rust removal cylinder 2. This causes the solution inside the rust removal cylinder 2 to flow, increasing the contact area between the solution and the DC motor components, thus ensuring the rust removal effect. After the DC motor components have been soaked for a certain period of time, the winding motor 303 is started. The winding motor 303 drives the reel 304 to rotate, winding the rope 305 and lifting the holding basket 306. When it is necessary to collect the filtered debris in the filter box 401, the solenoid valve in the connecting pipe 402 is closed, the box cover 405 is removed from the filter box 401, and the filter plate 5 fixed below the box cover 405 is also pulled out. After cleaning and collecting the debris on the filter plate 5, the box cover 405 is re-fixed to the top of the filter box 401.
