A protective plate for a slurry pump comprises a protective sleeve 1, a limiting groove 2 is provided on the front of the inner wall of the protective sleeve 1, a protective plate 3 is fixedly sleeved inside the limiting groove 2, a bolt 4 is sleeved on the inner thread of the protective sleeve 1, a positioning sleeve 5 is fixedly connected to the front of the protective sleeve 1, a No. 1 threaded rod 6 is sleeved on the inner thread of the positioning sleeve 5, a sealing gasket 7 is fixedly connected to the side of the protective sleeve 1, a feed pipe 8 is fixedly sleeved on the side of the protective sleeve 1, a No. 1 extrusion plate 9 is fixedly sleeved on the outside of the feed pipe 8, a No. 2 extrusion plate 10 is movably sleeved on the side of the No. 1 extrusion plate 9, a connecting mechanism 11 is arranged inside the No. 1 extrusion plate 9, a sealing ring 12 is fixedly sleeved on the side of the No. 2 extrusion plate 10, a heat sink 13 is fixedly connected to the outside of the protective sleeve 1, and a protective mechanism 14 is arranged on the outside of the protective sleeve 1.

[0025] The protective plate 3 is fixedly sleeved inside the protective sleeve 1, and the material of the protective plate 3 is manganese steel. By setting the protective plate 3, when the slurry pump is assembled, the protective plate 3 is sleeved inside the limiting groove 2. At this time, the bolt 4 is rotated so that the bolt 4 can fix the protective plate 3 inside the limiting groove 2, so that when the impeller inside the protective sleeve 1 drives the slurry to rotate inside the protective sleeve 1, the protective plate 3 can protect the inner wall of the protective sleeve 1, thereby avoiding the problem of rapid wear of the inner wall of the protective sleeve 1 caused by long-term friction between the slurry and the inner wall of the protective sleeve 1, thereby improving the service life of the protective sleeve 1, that is, improving the service life of the slurry pump guard plate.

[0026] There are four No. 1 threaded rods 6, and the four No. 1 threaded rods 6 are evenly distributed on the outside of the protective sleeve 1; by setting the No. 1 threaded rod 6, when the protective sleeve 1 needs to be installed and fixed, the No. 1 threaded rod 6 is rotated so that the No. 1 threaded rod 6 can squeeze and fix the protective sleeve 1 on the side of the slurry pump through the positioning sleeve 5, thereby achieving the fixing effect of the protective sleeve 1, and bringing convenience to the installation and fixation of the slurry pump guard plate.

[0027] The diameter of the sealing gasket 7 is the same as the diameter of the protective sleeve 1, and the material of the sealing gasket 7 is rubber material; by setting the sealing gasket 7, when the protective sleeve 1 is installed and fixed, the gap between the protective sleeve 1 and the slurry pump is filled with the inside of the sealing gasket 7, thereby improving the sealing performance of the protective sleeve 1 after it is fixed, avoiding the problem of slurry leaking from the gap of the protective sleeve 1 when it rotates rapidly, thereby improving the sealing effect of the slurry pump.

[0028] The connecting mechanism 11 includes a No. 2 threaded rod 111, which is threadedly sleeved on the inside of the No. 1 extrusion plate 9, and a nut 112 is threadedly sleeved on one end of the No. 2 threaded rod 111; by setting the connecting mechanism 11, when the feed pipe is connected, the No. 2 extrusion plate 10 is fixedly sleeved on the outside of the feed pipe, and the No. 2 threaded rod 111 is rotated at this time, so that the No. 2 threaded rod 111 and the nut 112 can squeeze and fix the No. 2 extrusion plate 10 and the No. 1 extrusion plate 9, thereby achieving the effect of fixed connection between the feed pipe and the feed pipe 8, thereby bringing convenience to the installation and use of the slurry pump.

[0029] The sealing ring 12 is movably sleeved on the outside of the feed pipe 8, and the material of the sealing ring 12 is rubber material; by setting the sealing ring 12, when the feed pipe 8 is connected, the sealing ring 12 can fill the gap between the No. 2 extrusion plate 10 and the No. 1 extrusion plate 9, thereby improving the air tightness inside the feed pipe 8, that is, improving the stability of the slurry during transportation.

[0030] The heat sink 13 is made of metal aluminum material, and there are several heat sinks 13, which are evenly distributed on the outside of the protective sleeve 1. By setting the heat sink 13, when the slurry inside the protective sleeve 1 rubs against the inner wall of the protective sleeve 1 for a long time, causing the temperature inside the protective sleeve 1 to rise, the heat sink 13 can absorb the heat inside the protective sleeve 1 and then discharge it to the outside of the protective sleeve 1, thereby increasing the heat dissipation rate inside the protective sleeve 1, that is, improving the heat dissipation effect of the slurry pump.

[0031] The protection mechanism 14 includes a fixing plate 141, which is movably sleeved on the outside of the No. 1 threaded rod 6, and a protection mesh cover 142 is fixedly sleeved on the side of the fixing plate 141; by setting the protection mechanism 14, when the slurry pump is assembled, the No. 1 threaded rod 6 is rotated so that the No. 1 threaded rod 6 can fix the protection mesh cover 142 on the outside of the protective sleeve 1 through the fixing plate 141, thereby achieving a closed covering effect of the protective sleeve 1, avoiding the problem of scalding of the user when the user touches the outside of the protective sleeve 1 with a higher temperature, thereby improving the safety of the slurry pump during long-term use.

[0032] The working principle of a guard plate for a slurry pump provided by the utility model is as follows:

[0033] The first step: first, when assembling the slurry pump, sleeve the protective plate 3 inside the limiting groove 2, and then rotate the bolt 4 so that the bolt 4 can fix the protective plate 3 inside the limiting groove 2, so that when the impeller inside the protective sleeve 1 drives the slurry to rotate inside the protective sleeve 1, the protective plate 3 can protect the inner wall of the protective sleeve 1, thereby avoiding the problem of rapid wear of the inner wall of the protective sleeve 1 caused by long-term friction between the slurry and the inner wall of the protective sleeve 1, thereby increasing the service life of the protective sleeve 1, that is, increasing the service life of the slurry pump guard plate. When the protective sleeve 1 needs to be installed and fixed, rotate the No. 1 threaded rod 6 so that the No. 1 threaded rod 6 can squeeze and fix the protective sleeve 1 on the side of the slurry pump through the positioning sleeve 5, thereby achieving the protective sleeve 1. The fixing effect brings convenience to the installation and fixing of the slurry pump guard plate. When the protective sleeve 1 is installed and fixed, the gap between the protective sleeve 1 and the slurry pump is filled inside the sealing gasket 7, thereby improving the sealing performance of the protective sleeve 1 after it is fixed, so as to avoid the problem of slurry leaking from the gap inside the protective sleeve 1 when it rotates rapidly, thereby improving the sealing effect of the slurry pump. When connecting the feed pipe, the No. 2 extrusion plate 10 is fixedly sleeved on the outside of the delivery pipe. At this time, the No. 2 threaded rod 111 is rotated, so that the No. 2 threaded rod 111 and the nut 112 can squeeze and fix the No. 2 extrusion plate 10 and the No. 1 extrusion plate 9, thereby achieving the effect of fixed connection between the delivery pipe and the feed pipe 8, thereby bringing convenience to the installation and use of the slurry pump;

[0034] Step 2: When connecting the feed pipe 8, the sealing ring 12 can fill the gap between the No. 2 extrusion plate 10 and the No. 1 extrusion plate 9, thereby improving the air tightness inside the feed pipe 8, that is, improving the stability during slurry transportation. When the slurry inside the protective sleeve 1 rubs against the inner wall of the protective sleeve 1 for a long time, causing the temperature inside the protective sleeve 1 to rise, a number of heat sinks 13 can absorb the heat inside the protective sleeve 1, and then discharge it to the outside of the protective sleeve 1, thereby increasing the heat dissipation rate inside the protective sleeve 1, that is, improving the heat dissipation effect of the slurry pump. When assembling the slurry pump, rotate the No. 1 threaded rod 6 so that the No. 1 threaded rod 6 can fix the protective mesh cover 142 on the outside of the protective sleeve 1 through the fixing plate 141, thereby achieving the closed covering effect of the protective sleeve 1, avoiding the problem of scalding of the user when the user touches the outside of the protective sleeve 1 with a higher temperature, thereby improving the safety of the slurry pump during long-term use.

[0035] Compared with the related art, the guard plate for a slurry pump provided by the utility model has the following beneficial effects:

[0036] By setting the protective plate 3, when the slurry pump is assembled, the protective plate 3 is sleeved inside the limiting groove 2, and the bolt 4 is rotated at this time so that the bolt 4 can fix the protective plate 3 inside the limiting groove 2, so that when the impeller inside the protective sleeve 1 drives the slurry to rotate inside the protective sleeve 1, the protective plate 3 can protect the inner wall of the protective sleeve 1, thereby avoiding the problem of rapid wear of the inner wall of the protective sleeve 1 caused by long-term friction between the slurry and the inner wall of the protective sleeve 1, thereby improving the service life of the protective sleeve 1, that is, improving the service life of the slurry pump guard plate.
