A connecting plate 5 is provided on one side of the pump cover 6, and an impeller 7 is provided inside the pump casing 8. The impeller 7 is driven to rotate by a rotating shaft 1, and a mechanical seal 5 is passed between the rotating shaft 1 and the pump cover 6. The rotating shaft 1 is connected to the frame 3 through a bearing housing 2, and a filter assembly 10 is installed on the impeller 7. The filter assembly 10 includes a transmission shaft 104 connected to the impeller 7, a crushing disk 1015 is fixedly installed at the end of the transmission shaft 104, a plurality of crushing blades 1014 are arranged on the crushing disk 1015, a fixed disk 107 is rotatably connected to the outer peripheral surface of the crushing blade 1014, an arc-shaped filter screen 109 is fixedly installed on the outer peripheral surface of the fixed disk 107, the arc-shaped filter screen 109 is in contact with the inner wall of the pump housing 8, and a circle of rubber ring can be arranged on the outer peripheral surface of the arc-shaped filter screen 109 to achieve sealing and extrusion.

During use, the sand pump first filters small stones through the arc filter 109, while large stones are retained by the arc filter 109 and flow to the fixed disk 107. At this time, the crushing disk 1015 and the crushing blades 1014 are driven to rotate by the transmission shaft 104, thereby crushing the large particles of impurities, and then continue to be discharged through the arc filter 109, thereby avoiding blockage.

A rotatable rotating disk 106 is sleeved on the transmission shaft 104, and a through hole 1011 through which the transmission shaft 104 passes is provided at the center of the rotating disk 106. Eight arc holes 1010 are arranged in an array on the rotating disk 106, and a connecting rod 108 is vertically arranged in each of the arc holes 1010. Eight straight holes 1012 are arranged in an array on the fixed disk 107, and a through hole 1011 through which the transmission shaft 104 passes is provided at the center of the fixed disk 107. One end of the connecting rod 108 passes through the straight hole 1012 provided on the fixed disk 107 and is connected to a slider 1017, and an extrusion knife 1016 is fixedly installed on the slider 1017.

The forward and reverse rotation of the rotating disk 106 drives the connecting rod 108 to reciprocate, and then the slider 1017 drives the extrusion knife 1016 to reciprocate. The reciprocating movement of the extrusion knife 1016 cooperates with the rotating crushing blade 1014 at the center to squeeze the large-grained stones toward the center, thereby accelerating the crushing of the large-grained stones.

A gear ring 103 is fixedly mounted on the outer circumferential surface of the rotating disk 106, a pushing cylinder 101 is movably connected to the pump housing 8, a gear 102 is movably connected to the piston rod of the pushing cylinder 101, the gear 102 is meshedly connected with the gear ring 103, and the pushing cylinder 101 is started to push the gear 102 to rotate forward and reverse, thereby driving the gear ring 103 to rotate forward and reverse, thereby realizing the reciprocating motion of the connecting rod 108.

A threaded shaft 105 is fixedly mounted on one end of the transmission shaft 104 , and the threaded shaft 105 is threadedly connected to the center of the impeller 7 .

During installation, the threaded shaft 105 is rotated and inserted into the impeller 7. When maintenance is required, the pump housing is opened and the threaded shaft 105 is removed to achieve disassembly.

Example 2

Based on Example 1, please refer to Figures 5-6, a hollow sleeve 121 is fixedly installed on the inner wall of the pump housing 8, and a gear ring 122 is rotatably connected to the outer surface of the hollow sleeve 121, which is convenient for water flow on the one hand and for the rotation of the gear ring 122 on the other hand. A protective plate 9 is fixedly installed on one side of the gear ring 122, which rotates through the gear ring 122, thereby driving the protective plate 9 to rotate.

Two threaded sleeves 126 are symmetrically arranged on the pump housing 8. The threaded sleeve 126 passes through the pump housing 8 and is fixedly connected to the second gear 123. The second gear 123 is meshed with the second gear ring 122. A push rod 124 is arranged on the side of the threaded sleeve 126 close to the second gear 123, and a rotating rod 125 is arranged on the side of the push rod 124 away from the second gear 123.

Rotate the rotating rod 125 to drive the threaded sleeve 126 to rotate, and then drive the gear 2 123 to rotate. The gear 2 123 drives the gear ring 2 122 to rotate, and then drives the protective plate 9 to rotate. Because the protective plate 9 may wear unevenly during use, the protective plate 9 is rotated to make the flow operation at the place with less wear.

The inner thread of the threaded sleeve 126 is connected with a threaded rod 127, and the threaded rod 127 passes through a bearing seat 129 and is connected with a knob 128. The bearing seat 129 is an L-shaped structure and is installed on the pump housing. The knob 128 is fixedly installed on the pump housing 8. The threaded sleeve 126 is provided with a locking bolt 1210, and the locking bolt 1210 is used to lock the threaded rod 127. Half of the outer surface of the threaded rod 127 is provided with threads, and the other half is not provided with threads, and the threaded rod 127 is provided with a locking hole that cooperates with the locking bolt 1210.

After the locking bolt 1210 is inserted into the locking hole, the threaded sleeve 126 is rotated and the threaded rod 127 will rotate together; when the locking bolt 1210 is pulled out, the threaded sleeve 126 is driven to move by rotating the threaded rod 127, and the threaded sleeve 126 moves, and then the toothed ring 122 is pushed to slide on the hollow sleeve 121 through the push rod 124, thereby pushing the protective plate 9 to move, and adjusting the distance between the protective plate 9 and the impeller to perform efficient work.

Both sides of the protection plate 9 are rotatably connected with elastic members 1211, one end of which is connected to the inner wall of the pump housing 8. The elastic member 1211 is composed of a spring and a guide rod. An annular T-shaped groove is provided on the protection plate 9, and a slider is provided in the T-shaped groove. The slider is connected to one end of the guide rod, and the other end of the guide rod is plugged into the inner wall of the pump housing 8. A spring is sleeved on the guide rod.

Working principle of the present invention: when the sand pump is in use, firstly, small stones are filtered through the arc filter 109, while large stones are retained by the arc filter 109 and flow to the fixed disk 107. At this time, the crushing disk 1015 and the crushing blade 1014 are driven to rotate through the transmission shaft 104, thereby crushing the large impurities; at the same time, the forward and reverse rotation of the rotating disk 106 is started to drive the connecting rod 108 to reciprocate, and then the extrusion knife 1016 is driven to reciprocate through the slider 1017. The extrusion knife 1016 reciprocates and cooperates with the rotating crushing blade 1014 at the center to squeeze the large stones to the center, thereby accelerating the crushing of the large stones; then continue to be discharged through the arc filter 109, thereby avoiding blockage;

When the protection plate 9 needs to be rotated, the rotating rod 125 is rotated to drive the threaded sleeve 126 to rotate, and then the second gear 123 is driven to rotate, and the second gear 123 drives the second gear ring 122 to rotate, and then the protection plate 9 is driven to rotate. Because the protection plate 9 may be unevenly worn during use, the protection plate 9 is rotated to make the flow operation at the place with less wear;

When the spacing needs to be adjusted, after the locking bolt 1210 is inserted into the locking hole, the threaded sleeve 126 is rotated and the threaded rod 127 will rotate together; when the locking bolt 1210 is pulled out, the threaded sleeve 126 is driven to move by rotating the threaded rod 127, and the threaded sleeve 126 moves, and then the toothed ring 122 is pushed to slide on the hollow sleeve 121 through the push rod 124, thereby pushing the protective plate 9 to move, and the distance between the protective plate 9 and the impeller is adjusted to perform efficient work.

The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
