Technical Field

[0001] This utility model relates to the field of permanent magnet processing technology, specifically to a permanent magnet synchronous motor permanent magnet processing equipment. Background Technology

[0002] Permanent magnets are magnets that can retain a high remanence for a long time in an open-circuit state. As an important component of permanent magnet synchronous motors, the size and shape errors in the processing and design structure of permanent magnets will affect the working performance of permanent magnet synchronous motors.

[0003] After permanent magnets are formed, they need to be ground and polished to remove burrs, flash, roughness, and other defects from the workpiece surface, making the surface smooth and shiny. However, after grinding and polishing, a large amount of grinding and polishing impurities adhere to the surface, requiring workers to clean it with water, which is troublesome, time-consuming, and labor-intensive. Therefore, this application proposes a permanent magnet processing equipment to solve the above problems. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is: a permanent magnet synchronous motor permanent magnet processing equipment, including: a main body mechanism and a circulation mechanism. The main body mechanism includes a box, a support ring fixed on the inner wall of the box, a mesh barrel placed on the top of the support ring and passing through the support ring, a partition plate fixed on the inner wall of the box, and ultrasonic generators symmetrically installed at the bottom of the partition plate.

[0006] The circulation mechanism includes a cylinder fixed to the bottom of the housing, an L-shaped drainage pipe connecting the cylinder to the inner cavity of the housing, a guide ring fixed to the inner wall of the cylinder, an annular filter screen with one end fixed to the guide ring and the other end fixed to the bottom wall of the cylinder, a sealing plug installed at the bottom of the cylinder and extending into the annular filter screen via a threaded connection, and a pump installed on the bottom wall of the housing.

[0007] In a preferred embodiment, the present invention can be further configured such that: the pump inlet is connected to the inner cavity of the cylinder through an inlet pipe, and the pump outlet is connected to the inner cavity of the box through an outlet pipe.

[0008] In a preferred embodiment, the present invention can be further configured such that: the partition is inclined and has a through hole on one side of the box, the through hole connecting the inner cavity of the box with the L-shaped drainage pipe.

[0009] In a preferred embodiment, the present invention can be further configured such that the inner bottom wall of the through hole is flush with the top surface of the partition.

[0010] In a preferred embodiment, the present invention can be further configured such that: a lifting ring is symmetrically fixed to the top of the mesh barrel.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] 1. In this utility model, a box is provided, and a support ring is fixed on the inner wall of the box for placing a mesh bucket. At the same time, a partition is fixed on the inner wall of the box. The partition is inclined, and an ultrasonic generator is symmetrically fixed at the bottom of the partition. With the above configuration, when in use, the polished permanent magnet is simply placed into the mesh bucket. At this time, the ultrasonic generator is activated. By using high-frequency vibration waves to act on the water in the box, bubbles and explosive force are generated to clean the stains and impurities on the surface of the permanent magnet. The cleaning efficiency is high and the effect is high, effectively increasing the cleaning efficiency after the permanent magnet is polished.

[0013] 2. In this utility model, a cylindrical body is fixed at the bottom of the housing, and an L-shaped drainage pipe is provided to connect the cylindrical body and the housing.

A sealing plug is installed at the bottom of the cylindrical body through a threaded connection and extends into the annular filter screen. A pump is installed on the inner bottom wall of the housing. One end of the pump is connected to the cylindrical body, and the other end is connected to the inner cavity of the housing. During use, impurities generated by ultrasonic cleaning dissolve in water. Wastewater enters the inner cavity of the cylindrical body through the L-shaped drainage pipe and finally enters the annular filter screen under the action of the guide ring. Impurities in the water are filtered by the annular filter screen. At the same time, the pump pumps the filtered water back into the housing, realizing water circulation in the inner cavity of the housing and filtering impurities in the water, further ensuring the high efficiency of cleaning.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0022] Combination Figure 1-3 As shown, this embodiment provides a permanent magnet synchronous motor permanent magnet processing equipment, including: a main body mechanism 100 and a circulation mechanism 200.

[0023] The main structure 100 includes a housing 110, a support ring 120 fixed to the inner wall of the housing 110, a mesh barrel 130 placed at the top of the support ring 120 and passing through the support ring 120, a partition 140 fixed to the inner wall of the housing 110, and ultrasonic generators 150 symmetrically installed at the bottom of the partition 140.

[0024] The housing 110 is used as a cleaning space and is filled with clean water. The support ring 120 is used to place the mesh bucket 130 and maintain the stability of the mesh bucket 130. Support legs are symmetrically fixed on both sides of the housing 110 to provide stable support for the housing 110.

[0025] The mesh bucket 130 is used to hold permanent magnets that need to be cleaned, making it convenient to put the permanent magnets in and out before and after cleaning. Pull rings are symmetrically fixed at the bottom of the mesh bucket 130 to facilitate moving the mesh bucket 130.

[0026] The partition 140 is inclined to facilitate the flow of impurities dissolved in the water into the circulation mechanism 200. The ultrasonic generator 150 is used to generate high-frequency vibrations. The high-frequency vibration waves act on the water in the chamber 110 to generate bubbles and explosive force, which cleans the stains and impurities on the surface of the permanent magnet. The cleaning efficiency is high and the effect is good.

[0027] The circulation mechanism 200 is used to circulate the water in the tank 110 and filter impurities in the water during the circulation process. It includes a cylinder 210 fixed to the bottom of the tank 110, an L-shaped drain pipe 220 connecting the cylinder 210 and the inner cavity of the tank 110, a guide ring 230 fixed to the inner wall of the cylinder 210, an annular filter screen 240 fixed at one end to the guide ring 230 and at the other end to the inner bottom wall of the cylinder 210, a sealing plug 250 installed at the bottom of the cylinder 210 and extending into the annular filter screen 240 by a threaded connection, and a pump 260 installed on the inner bottom wall of the tank 110.

[0028] The cylinder 210 is used to install other components. A through hole 111 is opened on one side of the box 110. The through hole 111 connects the inner cavity of the box 110 with the L-shaped drain pipe 220. The inner bottom wall of the through hole 111 is flush with the top surface of the partition 140, which facilitates the sewage in the box 110 to enter the L-shaped drain pipe 220. The L-shaped drain pipe 220 can guide the sewage into the inner cavity of the cylinder 210, which facilitates the filtration of the annular filter screen 240. The guide ring 230 is used to guide the sewage into the interior of the annular filter screen 240.

[0029] The annular filter screen 240 is used to filter impurities in sewage. The sealing plug 250 is installed at the bottom of the cylinder 210 by a threaded connection and extends into the inner cavity of the annular filter screen 240, which facilitates installation and disassembly, and makes it easy to clean the impurities accumulated inside the annular filter screen 240.

[0030] The pump 260 inlet is connected to the inner cavity of the cylinder 210 through the water inlet pipe 261, and the pump 260 outlet is connected to the inner cavity of the tank 110 through the water outlet pipe 262. With this configuration, the pump 260 draws out the filtered water through the water inlet pipe 261 and sends it back to the inner cavity of the tank 110 through the water outlet pipe 262, realizing water circulation in the inner cavity of the tank 110.

[0031] The working principle and usage process of this utility model are as follows: In use, the permanent magnet is placed into the mesh bucket 130, and the mesh bucket 130 containing the permanent magnet is placed into the housing 110, which is then placed on the support ring 120. Clean water is poured into the housing 110 until it covers the mesh bucket 130. The ultrasonic generator 150 is activated, using high-frequency vibration waves to act on the water in the housing 110, generating bubbles and explosive force to remove stains and impurities from the surface of the permanent magnet. Simultaneously, the impurities generated during cleaning dissolve in the water, and the wastewater enters through the through-hole 111 on the housing 110. The water is introduced into the L-shaped drain pipe 220 and then into the inner cavity of the cylinder 210. Under the action of the guide ring 230, it enters the annular filter screen 240. At this time, the impurities in the water are filtered by the annular filter screen 240. Simultaneously, the pump 260 starts and draws out the filtered water through the inlet pipe 261 and sends it back to the inner cavity of the tank 110 through the outlet pipe 262. Water circulation is achieved in the inner cavity of the tank 110. After cleaning, the mesh bucket 130 is removed from the tank 110 and the permanent magnet is reinstalled, so that the next round of permanent magnet cleaning can be carried out.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
