[0012] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0013] Embodiment: A fluid pump resistant to material abrasion and corrosion, such as Figure 1-Figure 2 As shown, it includes a shell 1, a feed port 2 is provided at the front end of the shell 1, a discharge port 3 is provided at the top of the shell 1, a mounting port 4 is provided at the rear end of the shell 1, the shell 1 is a hollow structure, the interior of the shell 1 includes a material passage cavity 5, a rear end cover 6 is installed in the mounting port 4 of the shell 1, the rear end cover 6 is fixedly connected to the mounting port 4 of the shell 1, a through-shaft hole 7 is provided at the center of the rear end cover 6, a bearing assembly 8 is provided in the through-shaft hole 7, a main shaft 9 is sleeved in the bearing assembly 8, and the main shaft 9 passes through The bearing assembly 8 is rotatably connected to the rear end cover 6. The front end of the main shaft 9 is arranged in the material passing cavity 5 of the shell 1. A plurality of slide grooves 10 are provided on the outer ring surface of the front end of the main shaft 9 in a circular array along the axis of the main shaft 9. Each of the slide grooves 10 is provided with a stirring blade, and the stirring blade includes a slider 11 connected to the slide groove 10 and a blade 12 located on the slider 11. The front end of the main shaft 9 is fixedly connected to a pressure plate 13 for pressing multiple stirring blades. The blades 12 and the inner cavity wall of the shell 1 are both covered with a wear-resistant rubber layer 14.

[0014] A countersunk hole 15 is provided at the center of the pressure plate 13, and a locking screw 16 is provided in the countersunk hole 15. The locking screw 16 is connected to the front end of the main shaft 9 to press the pressure plate 13 into multiple stirring blades; the diameter of the feed port 2 in the shell 1 is larger than the width of the blade; the feed port 2 and the mounting port 4 are coaxially arranged.

[0015] The principle of the present utility model is as follows: when in use, the material enters through the feed port 2 at the front end of the shell 1, and the rotation of the main shaft 9 drives the stirring blade to rotate, driving the material to be discharged from the discharge port 3. The wear-resistant rubber layer 14 on the inner surface of the shell 1 and the surface of the blade 12 can effectively prevent the material from wearing the shell 1 and the blade 12. Since the blade 12 rotates and contacts the material more, the wear will be relatively serious. By unscrewing the locking screw 16 and removing the pressure plate 13, the stirring blade can be removed from the front end of the main shaft 9 and taken out from the feed port 2 of the shell 1, which is convenient for maintenance of the pump.

[0016] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
