[0041] Embodiment 1:
[0042] Please refer to Figures 1 - 8 the structural schematic diagram, and the present invention provides the following technical solutions:
[0043] Specifically, it refers to a slurry pump with a wear-resistant inner lining of polymer material, including a slurry pump volute, a bottom filter slurry suction pipe, a water outlet elbow 51, a water outlet pipe 5, a second connecting branch pipe, a bearing cleaning mechanism, a water outlet positioning mechanism, a first connecting branch pipe, and a pump body drive mechanism.
[0044] The bottom filter slurry suction pipe is installed and fixed at the lower end of the slurry pump volute. The bottom filter slurry suction pipe can effectively filter large impurities, so that there will be no obstruction during the transportation of the slurry pump volute. The water outlet elbow 51 is installed and connected to the outer end of the slurry pump volute. The slurry transported by the slurry pump volute can be discharged through the water outlet elbow 51. The upper end of the water outlet elbow 51 is installed with a water outlet pipe 5. The water outlet elbow 51 can transport the slurry into the water outlet pipe 5, and then discharge it to a designated place for treatment to avoid polluting the external environment. The second connecting branch pipe is installed and fixed at the upper end position of the slurry pump volute to play a supporting role. The bearing cleaning mechanism is installed and fixed inside the second connecting branch pipe. The bottom of the bearing cleaning mechanism is located inside the slurry pump volute. The bearing cleaning mechanism can be stably placed through the second connecting branch pipe and receive external water sources to flush the inside of the slurry pump volute to avoid the adhesion of slurry. The water outlet positioning mechanism is installed and fixed on the periphery of the second connecting branch pipe to play a limiting role. The first connecting branch pipe is installed and fixed at the upper end of the second connecting branch pipe to enable corresponding installation and connection. The pump body drive mechanism is installed and fixed at the upper end of the first connecting branch pipe, so that it can be installed for the first time. The lower end of the pump body drive mechanism is located in the middle inside the slurry pump volute, so that the pump body drive mechanism can rotate and transport the slurry inside the slurry pump volute.
[0045] The slurry pump volute, the bottom filter slurry suction pipe, the water outlet elbow 51, the water outlet pipe 5, the second connecting branch pipe, the water outlet positioning mechanism, the first connecting branch pipe, and the pump body drive mechanism are all made of a polymer material with an inner lining, so as to have good wear resistance and strength.
[0046] The pump body drive mechanism includes a slurry pump motor 1. An electric motor sling 13 is fixedly connected to the outer wall of the slurry pump motor 1, so as to facilitate hoisting and moving during production. A bearing bracket 2 is installed at the lower end of the slurry pump motor 1 to enable corresponding installation and placement. A motor shaft rod 14 is key-connected to the output shaft of the slurry pump motor 1. When the output shaft of the slurry pump motor 1 rotates, it can drive the motor shaft rod 14 to rotate. A first coupling 12 is fixedly connected to the lower end of the motor shaft rod 14. When the motor shaft rod 14 rotates, it can drive the first coupling 12 to rotate. A rotating shaft rod 11 is fixedly connected to the lower end of the first coupling 12. The first coupling 12 can drive the rotating shaft rod 11 to rotate. An impeller 61 is fixedly connected to the lower end of the rotating shaft rod 11. The rotating shaft rod 11 can drive the impeller 61 to rotate in the volute housing 6 of the slurry pump volute, so that the volute housing 6 can effectively transport the slurry;
[0047] The rotating shaft rod 11 passes through the inside of the bearing housing 2, the first connecting branch pipe, the second connecting branch pipe and the slurry pump volute, so that it can be used for corresponding transmission.
[0048] The slurry pump volute includes a volute housing 6. Due to the internal shape of the volute housing 6, it is convenient to transport the slurry. An output volute pipe 64 is fixedly connected to the outer wall of the volute housing 6. The slurry inside the volute housing 6 can be transported to the output volute pipe 64 through the transmission of the impeller 61 and then discharged. A sealing disc 62 is installed in the middle of the upper end of the volute housing 6 to play a sealing role. A bottom bearing 63 is installed in the middle of the inner side of the sealing disc 62, so that the rotating shaft rod 11 can be positioned and rotated. The sealing disc 62 is installed and connected to the flushing ring disc 86. The flushing ring disc 86 can spray and flush the bottom bearing 63 on the sealing disc 62 through the spray flushing ring 88.
[0049] The bearing cleaning mechanism includes a flushing input pipe 8 fixedly connected to the connecting pipe body 83. The flushing input pipe 8 can receive the water source transported by the external water supply pump. The inner end of the flushing input pipe 8 passes through the inside of the connecting pipe body 83 and is installed with a conveying vertical pipe 84. The water source inside the flushing input pipe 8 can be transported to the conveying vertical pipe 84. A one-way valve 85 is installed at the lower end of the conveying vertical pipe 84. The conveying vertical pipe 84 can unidirectionally transport the water source through the one-way valve 85. The one-way valve 85 effectively prevents the slurry from being transported into the conveying vertical pipe 84, thus forming a backflow. The lower end of the one-way valve 85 is fixedly connected to an input end pipe 87. The one-way valve 85 can transport the cleaning liquid into the input end pipe 87. The lower end of the input end pipe 87 is fixedly connected to the flushing ring disc 86. The input end pipe 87 can transport the cleaning liquid into the flushing ring disc 86. A spray flushing ring 88 is installed at the inner inclined surface of the flushing ring disc 86. The water source inside the flushing ring disc 86 can be sprayed and flushed through the holes of the spray flushing ring 88. The flushing ring disc 86 is installed and connected to the slurry pump volute, so that it can be correspondingly installed and placed, and the spray flushing ring 88 can face the bottom bearing 63 of the upper slurry pump volute obliquely for flushing.
[0050] Working principle: During use, the operator installs the bottom-filtered slurry suction pipe in a container with slurry. The bottom-filtered slurry suction pipe can effectively filter out large impurities in the slurry through the filter mesh pipe 71. The slurry can be effectively transported into the slurry pump volute through the conveying pipe hole 73 inside the upper connecting pipe 72. The impeller 61 of the pump body drive mechanism rotates in the slurry pump volute, so that the slurry pump volute can effectively transport the slurry inside to the water outlet elbow 51, and then through the water outlet elbow 51 to the water outlet pipe 5. The water outlet pipe 5 is positioned by the water outlet positioning mechanism on the periphery of the second connecting branch pipe, so that stable transportation can be carried out. When the bottom bearing 63 of the slurry pump volute is used for a long time, slurry substances will adhere to it. The bearing cleaning mechanism receives the water source transported by the external water supply pump. Therefore, the flushing ring plate 86 of the bearing cleaning mechanism can effectively spray out the water source through the spray flushing ring 88, so that the water source sprayed by the spray flushing ring 88 can flush the bottom bearing 63 on the upper inner side, avoiding wear caused by a large amount of substances adhering to the bottom bearing 63.

[0052] Based on the specific Embodiment 1, the difference in this embodiment is as follows:

Symmetrically fixed on the outer wall of the connecting pipe 31 are side strengthening plates 3, which effectively strengthen the fixation, making the connecting pipe 31 not easily damaged by support. Between the two side strengthening plates 3 is fixed a strengthening semi-ring 32, which can effectively strengthen the connection of the side strengthening plates 3. The upper end of the connecting pipe 31 is installed and connected to the bearing bracket 2 by screws, so that corresponding installation can be carried out. The lower end of the connecting pipe 31 is installed and connected to the second connecting branch pipe by screws, so that corresponding installation can be carried out.
[0054] The second connecting branch pipe includes a connecting pipe body 83 installed on the connecting pipe 31 by screws, so that corresponding installation and connection can be carried out. In the middle of the inner sides at both ends of the connecting pipe body 83 are installed positioning bearings 81, which effectively limit the rotation of the rotating shaft rod 11, making the rotation of the rotating shaft rod 11 more stable. On the periphery of the positioning bearing 81 and on the connecting pipe body 83 is fixed a bracket connecting plate 82. The positioning bearing 81 can be stably placed on the inner side of the connecting pipe body 83 through the bracket connecting plate 82. An inner side of the connecting pipe body 83 is provided with a bearing cleaning mechanism, so that corresponding installation and connection can be carried out.
[0055] The bottom filtration slurry suction pipe includes a four-hole mounting plate 7. The four-hole mounting plate 7 can be correspondingly installed and placed by screws. The upper end of the four-hole mounting plate 7 is fixedly connected with a filter screen pipe 71. The filter screen pipe 71 can effectively filter large impurities through the mesh holes on the peripheral side, thus avoiding blockage and damage caused by transportation. The upper end of the filter screen pipe 71 is fixedly connected with an upper connecting pipe 72. A conveying pipe hole 73 is opened inside the upper connecting pipe 72. The upper connecting pipe 72 can convey the slurry through the conveying pipe hole 73. The upper end of the upper connecting pipe 72 is fixedly connected to the lower end of the slurry pump volute. The upper connecting pipe 72 can convey the slurry into the slurry pump volute.
[0056] Embodiment 3:
[0057] Based on the specific Embodiment 2, the difference in this embodiment is:
[0058] As Figure 1 and Figure 5 shown, the water outlet positioning mechanism includes a pipe body collar 42. An internal sleeve cavity 44 is opened inside the pipe body collar 42. A locking screw 41 is installed on the pipe body collar 42 on the inner side of the internal sleeve cavity 44. The pipe body collar 42 can be sleeved on the second connecting branch pipe through the internal sleeve cavity 44. The pipe body collar 42 is installed and connected to the peripheral side of the second connecting branch pipe through the locking screw 41, so that it can be stably placed. The outer wall of the pipe body collar 42 is fixedly connected with a clamping panel 4. An outer clamping groove 43 is opened on the inner side of the outer end of the clamping panel 4. The clamping panel 4 can clamp the peripheral side of the water outlet pipe 5 through the outer clamping groove 43. A closing screw 45 is installed on the clamping panel 4 on the inner side of the outer clamping groove 43. The closing screw 45 can effectively close the opening of the outer clamping groove 43 at the front end of the clamping panel 4, so that the clamping panel 4 can effectively clamp the water outlet pipe 5 for placement.
