When the main shaft rotates, it will drive the booster shaft sleeve and the crushing shaft sleeve to rotate together. The auger blade rotates at high speed, which can push the slurry to the left to the inside of the volute. The high-speed rotation of the crushing rod can crush and stir the slurry, laying a foundation for the impeller centrifugal pump.

The drive motor is then started, which drives the electric cylinder to extend, and the spring sleeve presses down the lifting frame. The lifting frame presses down the pneumatic cylinder, which presses down the pressure plate. The pressure plate enters the impeller disc and discharges the gas inside the impeller disc through the pneumatic valve, causing the crushed slurry block to extend and squeeze and clean the slurry in the slurry guide port. Regular maintenance is required without disassembling the pump body, which would affect its sealing performance. The slurry can be cleaned quickly, and the simple structure ensures stable operation of the slurry discharge.

[0046] To address the technical problem that existing slurry pumps have simple anti-clogging structures that are inconvenient to use, please refer to [the relevant documentation / reference]. Figure 2 -Figure 6 The following technical solutions are provided:

[0047] The pump body cover 2 is welded to the slag suction pipe 201. The slag suction pipe 201 is provided with a slag inlet 202.

A fixing ring 2083 is installed in the middle of the nine partition bars 2081, and the connecting rod 204 passes through the fixing ring 2083 and is fixedly connected to the anti-blocking disc 208.

[0049] The anti-clogging structure mounting cover 4 is provided with a mounting bracket 401 on its exterior. The mounting bracket 401 is used to fix the pump body cover 2 and the anti-clogging structure mounting cover 4. The outer surface of the anti-clogging structure mounting cover 4 is provided with a maintenance plate 402, which is sealed to the pump body cover 2 and the anti-clogging structure mounting cover 4.

[0050] Specifically, during use, an anti-clogging structure mounting cover 4 can be installed on the pump body cover 2. The pressure plate 406 inside the anti-clogging structure mounting cover 4 is used to squeeze and clean the slurry inside the pump body. The slurry is pumped by rotating the auger plate 203, the anti-clogging disc 208, and the impeller disc 206 through electric drive. During the pumping process, the slurry is introduced by the rotating auger plate 203. After being introduced, the slurry is broken up by the partition strip 2081, and the slurry is introduced into the slurry outlet pipe 1 through the slurry guide port 2082. The auger plate 203 and the anti-clogging disc 208 doubly break up the slurry to improve the flow effect of the slurry and improve the working quality.

[0051] To address the technical problem that existing anti-clogging structures are not very effective and thus affect usability, please refer to [the relevant documentation]. Figure 3 - Figure 5 The following technical solutions are provided:

[0052] A pneumatic valve is provided at the upper and lower ends of the pressure plate 406, and a bearing sleeve 205 is installed on the outside of the pressure plate 406. The pressure plate 406 is rotatably connected to the impeller disk 206 through the bearing sleeve 205. The lower end of the pressure plate 406 extends into the interior of the sealing connection plate 407 and fits against the crushed slag block 408.

The pneumatic cylinder 404 and the spring sleeve 602 keep the internal structural position of the pump body cover 2 stable. The slag block 408, which is limited by the tension spring, can perform stable unblocking work. Regular maintenance is required. The pump body does not need to be disassembled, which would affect its sealing performance. Slag can be cleaned quickly. The structure is simple and the slag discharge work is stable.

[0055] Please see Figure 1 - Figure 6 A method for discharging slurry using a vertical anti-clogging pump with a liquid guiding structure, comprising the following steps:

[0056] Step 1: After installing the slag discharge pipe 1 and the slag suction pipe 201, turn on the motor 5;

[0057] Step 2: The main shaft 501 drives the cage 503, guide shaft 504 and connecting rod 204 to rotate, and the connecting rod 204 drives the auger plate 203, anti-blocking disc 208 and impeller disc 206 to rotate;

[0058] Step 3: During the rotation of the impeller disk 206, the pump impeller 207 generates a suction force, which draws the slurry into the pump body through the slurry suction pipe 201. As the slurry enters the slurry suction pipe 201, it is introduced by the rotating auger plate 203. After being introduced, the slurry is dispersed by the partition bar 2081, allowing it to be introduced into the slurry pipe 1 through the slurry guide port 2082.

[0059] Step 4: After long-term operation, slurry adheres to the inner wall of the anti-clogging disc 208. Start the drive motor 601 to extend the electric cylinder 6, and the spring sleeve 602 presses down the lifting frame 403. The lifting frame 403 presses down the pneumatic cylinder 404, and the pneumatic cylinder 404 presses down the pressure plate 406. The pressure plate 406 enters the impeller disc 206 and discharges the gas inside the impeller disc 206 through the pneumatic valve, causing the crushed slag block 408 to extend and squeeze and clean the slurry in the slag guide port 2082.

[0060] Step 5: The liquid generated by squeezing the slurry is collected through the liquid guide pipe 3, discharged through the filter screen 301, and continuously discharged through the slag suction pipe 201.

[0061] Working Principle: During operation, after installing the slag discharge pipe 1 and slag suction pipe 201, close the liquid guide pipe 3 to extract the slurry. Power on the motor 5, and the main shaft 501 drives the retainer 503, guide shaft 504, and connecting rod 204 to rotate. The connecting rod 204 drives the auger plate 203, anti-clogging disc 208, and impeller disc 206 to rotate, thus performing slurry extraction. During extraction, the rotating auger plate 203 introduces the slurry. After introduction, the slurry is broken up by the partition strip 2081, allowing it to be introduced into the slag discharge pipe 1 through the slag guide port 2082. The auger plate 203 and anti-clogging disc 208 perform double slurry breaking to improve slurry flow. After prolonged operation, slurry adheres to the inner wall of the anti-clogging disc 208. Start the drive motor 601, which extends the electric cylinder 6, and the spring sleeve 602 presses down the lifting frame 403. The lifting frame 403 presses down the pneumatic cylinder 404, which in turn presses down the pressure plate 406. The pressure plate 406 enters the impeller disk 206 and discharges the gas inside the impeller disk 206 through the pneumatic valve, causing the crushed slag block 408 to extend. This squeezes and cleans the slag in the slag guide port 2082. The pneumatic cylinder 404 and the spring sleeve 602 keep the internal structural position of the pump body cover 2 stable. The crushed slag block 408, which is limited by the tension spring, can perform stable unblocking work. Regular maintenance is required without disassembling the pump body, which would affect its sealing performance. It can quickly clean slag, and its simple structure makes the slag discharge work stable. The liquid generated by squeezing the slag is collected through the liquid guide pipe 3, discharged through the filter screen 301, and continuously discharged through the slag suction pipe 201. The slag is circulated and extracted, which helps to improve the use effect.

9. A method for discharging slurry using a vertical anti-clogging pump with a liquid guiding structure according to claim 8, characterized in that, Includes the following steps: Step 1: After installing the slag discharge pipe (1) and slag suction pipe (201), power on the motor (5); Step 2: The main shaft (501) drives the cage (503), guide shaft (504) and connecting rod (204) to rotate, and the connecting rod (204) drives the auger plate (203), anti-blocking disc (208) and impeller disc (206) to rotate; Step 3: During the rotation of the impeller disc (206), the suction force generated by the rotation of the pump impeller (207) is used to draw the slurry into the pump body through the slurry suction pipe (201). During the process of the slurry entering the slurry suction pipe (201), the rotating auger blade (203) introduces the slurry. After introduction, the slurry is dispersed by the partition bar (2081) and introduced into the slurry discharge pipe (1) through the slurry guide port (2082). Step 4: After long-term operation, slurry adheres to the inner wall of the anti-clogging disc (208).
