[0002] Magnetic pumps, also known as magnetic drive pumps, are mainly composed of pump heads, magnetic transmissions, motors, bases and other parts. The magnetic transmission of magnetic pumps consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through a coupling, the magnetic field can penetrate the air gap and the non-magnetic isolation sleeve, driving the inner magnetic rotor connected to the impeller to rotate synchronously. The contactless torque transmission method of the internal and external magnetics replaces the dynamic seal with a static seal, achieving the technical purpose of leakage-free pumping.

[0003] When a magnetic pump is used to transport liquids, due to the wide variety of liquids being pumped, there will be certain impurities in some liquids. If the transported liquid contains solid impurities, the impurities will collide with the high-speed running impeller when entering the impeller inside the pump body, which can easily cause damage to the impeller. When the solid impurities are large, the impeller may become stuck, causing serious damage to the impeller components of the pump body. For this reason, a magnetic pump with an anti-clogging structure is proposed. Utility Model Content

[0023] For examples, see Figure 1-6 The utility model provides a technical solution: a magnetic pump with an anti-blocking structure, including a magnetic pump body 1 and an anti-blocking mechanism. The magnetic pump body 1 is a magnetic pump body. Specifically, the model of the magnetic pump body 1 can be HTP-31. Figure 1As shown, in order to realize magnetic transmission, a magnetic coupling seat 3 and a pumping seat 4 are provided at the end side of the magnetic pump body 1. The magnetic coupling seat 3 is fixedly installed on the front end side of the magnetic pump body 1 by bolts, so that the power of the motor side of the magnetic pump body 1 can be transmitted to the pumping seat 4. The pumping seat 4 is fixedly installed on the front end side of the magnetic coupling seat 3 by bolts for pressurized delivery of water. The pumping seat 4 is installed on the end side of the magnetic pump body 1 through the magnetic coupling seat 3. In order to realize water pressurization, an impeller is provided inside the pumping seat 4. In order to facilitate the installation and support of the magnetic pump body 1, a pump body support 2 is provided at the bottom of the magnetic pump body 1. The lower part of the magnetic pump body 1 is fixedly installed with the pump body support 2 by bolts. The pump body support 2 can provide a stable installation support for the operation of the magnetic pump body 1.

[0024] In order to facilitate the installation of water circulation connection, as shown in the attached Figure 2 As shown, the liquid inlet end tube 5 and the liquid outlet end tube 6 are fixedly connected and installed on the front side and the upper part of the side of the pumping seat 4 respectively, and the anti-blocking mechanism is connected and installed on the end side of the pumping seat 4. The anti-blocking mechanism includes a filter end tube 7, a connecting end tube 8, a conical filter cover 9 and a cleaning brush 10. The filter end tube 7 is used for the installation support of the conical filter cover 9. The filter end tube 7 is detachably installed on the end side of the pumping seat 4. Specifically, in order to facilitate the connection and installation with the filter end tube 7, a thread is provided on the outer peripheral side of the end of the liquid inlet end tube 5, and the rear part of the filter end tube 7 is fastened to the front part of the liquid inlet end tube 5 by thread.

[0025] The conical filter cover 9 is a conical cover made of stainless steel, which is used to filter and separate solid impurities in water. In order to facilitate the circulation of water, filter holes 12 are evenly set on the circumference of the conical filter cover 9. The rear part of the conical filter cover 9 is penetrated by a flow guide groove. In order to facilitate the connection and installation of the conical filter cover 9, as shown in the attached figure, the filter holes 12 are evenly set on the circumference of the conical filter cover 9. Figure 3 The filter cover 9 is a kind of filter that is convenient to install and is convenient to operate.

[0026] The cleaning brush 10 is used for brushing and cleaning the inner side of the conical filter cover 9. The cleaning brush 10 is installed on the inner side of the conical filter cover 9 by rotating the shaft. Figure 6 As shown, the end seat of the cleaning brush 10 is installed in a suitably mounted manner with the shaft column, and a fastening bolt 13 is provided at the front of the shaft column of the cleaning brush 10. The end seat of the cleaning brush 10 is fixedly mounted to the front of the shaft column by the fastening bolt 13. The cleaning brush 10 is a flexible brush body, which can reduce the risk of getting stuck with dirt during rotation. After installation, the end of the cleaning brush 10 contacts the inner surface of the conical filter cover 9. The filter holes 12 on the side of the conical filter cover 9 that are more easily clogged can be effectively prevented from adhering and accumulating sticky dirt by brushing. In order to facilitate the rotation of the cleaning brush 10, a support is installed, as shown in the attached figure. Figure 5 As shown, a shaft sleeve 14 is fixed to the middle of the rear side of the conical filter cover 9, the rear part of the shaft is rotatably installed on the inner side of the shaft sleeve 14, and the driving impeller 11 is fixedly installed on the rear end of the shaft. The cleaning brush 10 is a flexible brush body and the rotational driving force is increased by driving the impeller 11. The driving impeller 11 is driven by the water flow generated by the operation of the magnetic pump body 1, and no additional power supply is required. By brushing the inside of the cleaning brush 10, the blockage of holes caused by the accumulation of dirt and algae growth can be effectively avoided, which greatly improves the working reliability of the device.

[0027] The working principle or structural principle is that the cleaning brush 10 is pre-installed inside the conical filter cover 9 through the rotating shaft. Before work, the conical filter cover 9 is first aligned and fitted into the inner side of the embedded notch at the front of the filter end tube 7, and then the connecting end tube 8 is screwed and installed at the front of the filter end tube 7. The fastening and limiting of the installed conical filter cover 9 is completed by tightening and pushing the rear end of the connecting end tube 8. Then, the rear end of the filter end tube 7 is fastened to the liquid inlet end tube 5 of the magnetic pump body 1 through threaded fastening to complete the assembly of the pump body. When working, the impeller in the pumping seat 4 on the end side of the magnetic pump body 1 rotates to generate suction through the transmission of the magnetic coupling seat 3. Under the action of suction, external liquid enters the filter end tube 7 through the pipeline, and the solid impurities in the water are filtered and separated by the conical filter cover 9 in the filter end tube 7. At the same time, driven by the flowing water, the driving impeller 11 drives the cleaning brush 10 to rotate, and the brush head of the cleaning brush 10 brushes the inner side of the conical filter cover 9 to prevent dirt from adhering to and accumulating on the surface of the conical filter cover 9. When cleaning, you only need to loosen and remove the connecting end tube 8 on the end side of the filter end tube 7, and then take out the conical filter cover 9 as a whole by buckling and pulling for cleaning, and then install and reset the conical filter cover 9 and the connecting end tube 8 in turn to complete the cleaning work.

[0028] In summary, the magnetic pump adopts a filter cover type anti-blocking structure. The conical filter cover 9 is installed in an embedded manner inside the filter end tube 7 and is supported and limited by the connecting end tube 8. The structure is simple and easy to disassemble and assemble. The conical filter cover 9 can effectively filter and separate the solid impurities in the liquid entering the magnetic pump body 1, and can effectively protect the impeller in the magnetic pump body 1, which can effectively improve the working stability and service life of the pump body. A cleaning brush 10 is provided inside the conical filter cover 9. The cleaning brush 10 is a flexible brush body and increases the rotational driving force by driving the impeller 11. The driving impeller 11 is driven by the water flow generated by the operation of the magnetic pump body 1. No additional power supply is required. By brushing the inner side of the cleaning brush 10, the blockage of holes caused by the accumulation of dirt and algae growth can be effectively avoided, which greatly improves the working reliability of the device.
