Description

Technical Field

[0001] The utility model relates to the technical field of slurry pumps, in particular to a slurry pump with a protective structure. Background Art

[0002] A slurry pump is a type of pump equipment specially used to transport high-concentration, high-density solid particles.

[0003] Today's slurry pumps are mainly composed of a pump base, a pump cover and a jacket. The material enters the jacket from the pump cover and is then discharged from the top outlet of the jacket. Therefore, when connecting external equipment to the slurry pump, the external equipment is directly fixed to the top of the pump base and the pump cover through a flange connection. However, the pump base and the pump cover are separated, and the height of the jacket is different from that of the pump base and the pump cover. As a result, after the external equipment is connected to the slurry pump, the material may leak during transportation. If the material is corrosive, it will cause damage to the area around the jacket outlet. For this reason, we propose a slurry pump with a protective structure. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-Figure 3 A slurry pump with a protective structure shown includes a pump base 101 and a docking mechanism. A pump cover 102 is provided on the front of the pump base 101, and a sleeve 103 is provided between the pump base 101 and the pump cover 102. Inlets are provided on the front of the pump cover 102 and the sleeve 103. The material enters from the inlet and is then discharged from the top of the sleeve 103.

[0021] In a preferred embodiment, the docking mechanism is arranged at the top of the sleeve 103, and the docking mechanism includes a pressure ring 202, the top of the pressure ring 202 is provided with an external mechanism, the bottom end of the pressure ring 202 is provided with an annular groove 203, the top of the sleeve 103 and the inner movably interlaced connection of the annular groove 203, the top of the outer wall of the sleeve 103 is provided with a first frustum 201, the inner wall of the annular groove 203 is provided with a second frustum 204, and a sealing mechanism is provided between the pressure ring 202 and the sleeve 103. When connecting the pump seat 101 to an external device, the external mechanism is first connected to the pump seat. 101 is connected. During the connection process, the annular groove 203 at the bottom end of the pressure ring 202 is used to clamp the top of the sleeve 103, so that the surface of the second frustum 204 is tightly against the surface of the first frustum 201. At this time, the sealing between the external mechanism and the sleeve 103 can be completed, and then the external equipment can be connected to the external mechanism, so that the pump base 101 can work, and there will be no leakage at the discharge port of the pump base 101, thereby avoiding damage to the area around the discharge port of the pump base 101 by corrosive materials, thereby improving the protection effect of the slurry pump.

[0022] Among them, the sealing mechanism includes a rubber ring 301, which is arranged between the pressure ring 202 and the sleeve 103. The rubber ring 301 is inserted into the inside of the annular groove 203. The inner diameter of the rubber ring 301 is the same as the inner diameter of the sleeve 103. When the pressure ring 202 is connected to the sleeve 103, the rubber ring 301 is first clamped in the annular groove 203, and then the pressure ring 202 is put on the top of the sleeve 103 until the surface of the second frustum 204 squeezes the surface of the first frustum 201. The rubber ring 301 is also squeezed by the top of the sleeve 103, so that the rubber ring 301 is deformed, which further increases the sealing effect between the pressure ring 202 and the sleeve 103.

[0023] Among them, the external connection mechanism includes a connecting pipe 401, the bottom end of the connecting pipe 401 is fixedly connected to the top of the pressure ring 202, the outer wall of the connecting pipe 401 is provided with a connecting mechanism, and a fixing mechanism is provided between the connecting pipe 401 and the pump seat 101. The connecting mechanism includes a first connecting ring 402, and the first connecting ring 402 is fixedly sleeved on the top of the outer wall of the connecting pipe 401. The top of the first connecting ring 402 is provided with multiple first connecting holes 403 in a circular array. The connecting pipe 401 is directly connected to the external equipment, and through the cooperation of the first connecting ring 402 and the first connecting hole 403, the traditional flange connection is realized, that is, under the cooperation of the docking mechanism and the external connection mechanism, after the pump seat 101 is connected to the external equipment, there will be no leakage during the transportation of materials.

[0024] Among them, the fixing mechanism includes a second connecting ring 501, the second connecting ring 501 is fixedly sleeved on the bottom of the outer wall of the connecting pipe 401, and the top of the pump seat 101 and the pump cover 102 is fixedly connected with a third connecting ring 502. The tops of the second connecting ring 501 and the third connecting ring 502 are each provided with a plurality of second connecting holes 503. The inner walls of two adjacent second connecting holes 503 are movably connected with fixing bolts 504. The outer wall of the fixing bolt 504 is threadedly connected with a fixing nut 505. The fixing nut 505 is arranged above the second connecting ring 501, and the outer wall of the fixing bolt 504 is provided with an anti-slip mechanism. Then the connecting pipe 401 is fixed to the pump seat 101, and the second connecting ring 501 is placed on the third connecting ring. The top of the connecting ring 502 is adjusted, and the second connecting hole 503 corresponds one to one. At this time, the top of the sleeve 103 is automatically aligned and inserted into the inside of the annular groove 203, and then the fixing bolt 504 is inserted into the second connecting hole 503 from the bottom end of the third connecting ring 502 until the fixing bolt 504 is inserted out of the second connecting hole 503 at the top of the second connecting ring 501, and then the fixing nut 505 is tightened on the outer wall of the fixing bolt 504. During the tightening process, the distance between the second connecting ring 501 and the third connecting ring 502 gradually decreases until the surface of the second frustum 204 tightly squeezes the surface of the first frustum 201. At this time, the rubber ring 301 is also compressed, thereby improving the docking work of the docking mechanism.

[0025] Among them, the anti-slip mechanism includes an elastic washer 601, which is sleeved on the outer wall of the fixing bolt 504. The elastic washer 601 is arranged between the second connecting ring 501 and the third connecting ring 502. Before the fixing mechanism is fixed, the elastic washer 601 needs to be placed between the second connecting ring 501 and the third connecting ring 502 and aligned with the second connecting hole 503, so that the fixing bolt 504 is inserted into the second connecting hole 503 and the elastic washer 601 at the same time, so that the fixing nut 505 can be tightened. When the distance between the second connecting ring 501 and the third connecting ring 502 gradually decreases, the elastic washer 601 will be squeezed by the second connecting ring 501 and the third connecting ring 502, causing the elastic washer 601 to deform. The deformed elastic washer 601 will provide a reverse squeezing force to the second connecting ring 501 and the third connecting ring 502, so that the tightened fixing nut 505 is not easy to loosen from the fixing bolt 504, thereby improving the stability of the fixing mechanism and thus improving the stability of the external mechanism.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
