[0025] The flowing medium first contacts the filter cartridge 402. If there are any larger individuals, they will be intercepted by the filter cartridge 402. Other media will continue to flow through the filter cartridge 402. The intercepted individuals will fall into the space formed by the extension ring 401 and the closing cover 403 at the bottom under the action of gravity. After a period of time, the connecting piece 404 is disassembled. At this time, the closing cover 403 is no longer restricted and can be easily removed. The intercepted impurities can also be quickly excreted, effectively preventing larger individuals from entering the pump body 1 and causing blockage that affects the normal operation of the device.

[0026] like Figure 2 As shown, a rubber ring 405 is provided on the inner wall of the bottom of the closing cover 403 , and the rubber ring 405 can fit with the lower surface of the extension ring 401 , so that the sealing between the closing cover 403 and the extension ring 401 is stronger.

[0027] like Figure 2 As shown, the side of the filter cartridge 402 close to the outside is set as an inclined surface, and the inclined surface is set toward the extension ring 401. When larger individuals of the medium touch the inclined surface, they will fall into the extension ring 401 along the inclined surface, avoiding the accumulation of large individuals affecting the normal flow of the medium.

[0028] like Figure 3 and Figure 4 As shown, a mounting plate 5 is installed inside the pump body 1 , and an impeller assembly 6 is installed outside the mounting plate 5 .

At this time, the position of the mounting plate 601 is no longer restricted. At this time, just pull the mounting plate 601 to easily remove it, thereby avoiding the entire impeller from being discarded and causing a waste of resources. The positioning block 603 can enable the mounting plate 601 to quickly reach a suitable position and also have the effect of reinforcing the mounting plate 601.

[0031] like Figure 4 As shown, a plurality of grooves 605 are formed on the outer wall of one side of the mounting plate 5 , and a plurality of bolts 604 can respectively enter the plurality of grooves 605 , so that the bolts 604 will not affect the normal rotation of the mounting plate 5 .

[0033] The utility model provides a single-impeller slurry pump, the specific working principle of which is as follows:

[0034] When the device is working, the external medium flows from the liquid inlet pipe 3 to the inside of the pump body 1. The flowing medium first contacts the filter cartridge 402. If there are larger individuals, they will be intercepted by the filter cartridge 402. Other media will continue to flow through the filter cartridge 402. The intercepted individuals will fall into the space formed by the extension ring 401 and the closing cover 403 at the bottom under the action of gravity. After a period of time, the connecting piece 404 is disassembled. At this time, the closing cover 403 is no longer restricted and can be easily removed. The intercepted impurities can also be quickly excreted, effectively avoiding In case larger individuals enter the pump body 1 and cause blockage, affecting the normal operation of the device, as the use time increases, if one or several blades 602 are damaged due to wear, just turn the corresponding bolts 604 to make them disengage from the mounting disk 5. At this time, the position of the mounting plate 601 is no longer restricted. At this time, just pull the mounting plate 601 to easily remove it, thereby avoiding the entire impeller from being discarded, thereby causing a waste of resources. The positioning block 603 can enable the mounting plate 601 to quickly reach a suitable position, and can also have the effect of reinforcing the mounting plate 601.
