[0003] A search of CN220015506U discloses a slurry pump with a stirring and chopping device. The slurry pump body, filter tube, mounting plate, telescopic spring, shock absorbing device and U-shaped bottom plate are used in combination. The pump has stirring, chopping and shock absorbing functions. When in use, larger particles can be directly crushed to prevent large particles from colliding with the inside of the slurry pump and causing damage. At the same time, the slurry pump can be shock-absorbing to prevent the equipment from shaking and tipping over during use.

A fixing rod 319 is fixedly connected to the inner wall of the filter frame 321, and a rotating hole is opened on the outer wall of the fixing rod 319. The inner wall of the rotating hole is rotatably connected with a screw rod 3110, and a threaded rod 3111 is threadedly connected to the outer wall of the screw rod 3110. A limiting groove is opened at the bottom end of the inner wall of the filter frame 321, and the outer wall of the threaded rod 3111 is slidably connected to the inner wall of the limiting groove. A cleaning rod 3112 is fixedly connected to the outer wall of the threaded rod 3111 away from the screw rod 3110, and a slot 3113 is opened at one end of the screw rod 3110, and the outer wall of the insert block 318 is clamped on the inner wall of the slot 3113.

[0028] Furthermore, a through groove is provided on the outer wall of the connecting pipe 311, and a groove is provided on the inner wall of the through groove. A sealing baffle is slidably connected to the inner wall of the groove, and one end of the sealing baffle is fixedly connected to the outer wall of the lever 317. In this way, when the lever 317 is moved, the sealing baffle will slide on the inner wall of the groove, thereby sealing the through groove through the sealing baffle to prevent leakage of slurry.

[0029] Furthermore, the outer wall of the plug block 318 fits snugly with the inner wall of the slot 3113, and the plug block 318 is in a cross shape, so that the two are more stable after being snapped together. At the same time, the cross shape can better limit the rotation stability after being snapped together.

[0030] Furthermore, there are two cleaning rods 3112, and the cleaning rods 3112 are distributed on the left and right sides of the threaded rod 3111 in a left-right symmetrical structure. The end of the cleaning rod 3112 away from the threaded rod 3111 is attached to the inner wall of the filter frame 321, so that the cleaning rod 3112 can push and clean the particulate impurities at the bottom end of the inner wall of the filter frame 321 to the discharge port and then discharge them through the discharge pipe.

[0031] The filter disassembly and assembly mechanism 32 includes a mounting groove provided at the bottom end of the inner wall of the filter frame 321, a filter screen 322 is clamped on the inner wall of the mounting groove, a connecting rod 323 is fixedly connected to the outer wall of the filter screen 322, a support frame 324 is fixedly connected to the outer wall of the filter frame 321, a sliding hole is provided on the outer wall of the support frame 324, a spring 325 is fixedly connected to the inner wall of the sliding hole, a top block 326 is fixedly connected to the end of the spring 325 away from the inner wall of the sliding hole, and the outer wall of the top block 326 is slidably connected to the inner wall of the sliding hole.

[0032] Furthermore, inclined surfaces are provided at the upper and lower ends of the top block 326. There are two top blocks 326 that are symmetrically distributed on the left and right sides of the filter frame 321. Through the inclined surface, the top block 326 can be squeezed when the connecting rod 323 moves upward or downward, thereby facilitating the staff to disassemble and assemble the filter net 322.

[0033] Furthermore, a rubber block is provided at one end of the top block 326 away from the spring 325, and the inner wall of the sliding hole opened on the outer wall of the support frame 324 fits closely with the outer wall of the top block 326. When the top block 326 is reset, the rubber block can be pushed to abut against the inner outer wall of the connecting rod 323, thereby increasing the friction limiting force between the two, thereby further improving the installation stability of the filter screen 322.

[0034] The implementation principle of the explosion-proof slurry pump for stirring and chopping in this embodiment is as follows: first, the slurry pump 2 and the double-axis motor 313 are started synchronously, and then the slurry is sucked into the connecting pipe 311. At this time, the double-axis motor 313 drives the rotation and the crushing knife 315 to rotate. The crushing knife 315 can crush larger particles of impurity solids into small pieces of solid particles, so that larger particles of solids can be prevented from flowing into the slurry pump 2 and affecting the pressure inside the slurry pump 2. In this way, the slurry pump 2 can be explosion-proof and the safety of use can be improved. When it is necessary to clean the impurity particles in the filter frame 321, first, the lever 3 is toggled to the left. 17, thereby driving the extension portion of the telescopic rod 316 to extend, thereby driving the insert block 318 to be inserted into the slot 3113, so that it can be connected with the screw rod 3110 in a limited position, so that when the telescopic rod 316 rotates, it can drive the screw rod 3110 to rotate, thereby driving the threaded rod 3111 to move to the left, and when the threaded rod 3111 moves, it will drive the cleaning rod 3112 to push and clean the impurities accumulated at the bottom of the filter frame 321 until it is pushed to the discharge port and then discharged through the discharge pipe, so that the accumulated particulate solids can be cleaned to prevent long-term accumulation from causing blockage and affecting the slurry pumping work of the slurry pump 2.

[0035] The slurry can be filtered through the filter screen 322, and a large amount of particulate solids can be filtered to prevent clogging of the slurry pump 2. When the filter screen 322 needs to be removed, it is only necessary to pull the connecting rod 323 upward to move it upward, thereby driving the filter screen 322 to move upward. During the movement of the connecting rod 323, its bottom end will contact and squeeze the top block 326. The squeezed top block 326 can move inward to squeeze the spring 325 until the top block 326 is completely separated from the limiting effect of the bottom end of the connecting rod 323. In this way, the filter screen 322 can be removed. During installation, it is only necessary to insert the filter screen 322 into the filter frame 321 until the bottom end of the connecting rod 323 moves to the bottom end of the top block 326, and then the spring 325 rebounds to push the top block 326 to return to the limit position of the connecting rod 323, and the installation is completed.
