Description

Technical Field

[0001] This utility model relates to the field of slurry pump technology, and more specifically, to a slurry pump sealing structure that can be quickly disassembled. Background Technology

[0002] The sealing structure of a slurry pump is a key component in ensuring that the pump does not leak during operation, especially when handling fluids containing solid particles. An effective sealing design can not only reduce media leakage but also extend the service life of the equipment and improve work efficiency.

[0003] However, the connection between the sealing components of the slurry pump sealing structure and the pump cover and slurry pump is not stable enough. During the operation of the slurry pump, it is easily loosened by factors such as vibration and pressure, which affects the sealing effect and the reliability of the equipment. At the same time, the assembly and disassembly process of the slurry pump sealing structure is often complicated and cumbersome, usually requiring the use of multiple tools, and the operation steps are numerous and time-consuming. This greatly reduces work efficiency when regular maintenance is required or when there is a sudden failure.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a slurry pump sealing structure that can be quickly disassembled, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A quick-disassembly slurry pump sealing structure includes a slurry pump and a sealing assembly. The sealing assembly includes a sealing gasket on one side of the slurry pump, a pump cover on one side of the sealing gasket, a sealing rod and a sealing cylinder connected to the pump cover, the slurry pump and the sealing gasket respectively, and a threaded connection between the inner wall of the sealing cylinder and one end of the sealing rod.

[0008] Furthermore, to improve the sealing performance of the slurry pump's delivery and output points, a second sealing component is provided on the pump cover and the slurry pump. The second sealing component includes a second sealing gasket on the pump cover and the slurry pump, and multiple sealing covers on the sealing gasket and the slurry pump and pump cover. One end of the sealing cover is hinged to a rotating shaft, and the other end of the sealing cover has an auxiliary groove. A rotating rod is connected to the inner wall of one of the auxiliary grooves, and a limiting rod is threadedly connected to one of the sealing covers.

[0009] Furthermore, in order to better improve the tightness of the connection between the second sealing gasket, the first sealing gasket, and the joint, there are equally spaced snap-fit ​​blocks on both sides of the second sealing gasket and the first sealing gasket. One end of the snap-fit ​​block snaps into the pump cover and the slurry pump.

[0010] Furthermore, in order to better connect the slurry pump to the output, one end of the locking block of the sealing gasket two is locked with a sealing seat, and the outer periphery of the sealing seat contacts the inner wall of the sealing cover.

[0011] Furthermore, to facilitate easier disassembly, anti-slip sleeves are provided on the limiting rod and sealing rod, and the anti-slip sleeves are compatible with the limiting rod and sealing rod.

[0012] Furthermore, in order to better improve the stability of the slurry pump, a support base is provided on the surface of the slurry pump, and an auxiliary cover is installed on the support base.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By installing sealing component one and sealing component two in the slurry pump, not only can the sealing component be stably connected to the pump cover and the slurry pump, which is conducive to the sealing structure resisting vibration, pressure and other factors during operation, reducing loosening, improving equipment reliability and sealing effect, but also can be easily disassembled and assembled without complicated tools, simplifying the disassembly and assembly process of the slurry pump sealing structure, reducing operation steps and time consumption, improving maintenance efficiency, and enabling staff to quickly disassemble the sealing component for inspection, repair or replacement, and assemble and resume production in a short time, reducing downtime caused by maintenance or failure, and improving work efficiency.

[0015] (2) By setting the snap-fit ​​blocks on sealing gasket one and sealing gasket two, the sealing performance between the pump cover and the slurry pump, and between the slurry pump delivery and output points can be improved, forming multiple sealing barriers, effectively preventing slurry leakage, ensuring that the sealing performance of the sealing structure remains stable during the long-term operation of the slurry pump, reducing problems such as media loss, environmental pollution and equipment instability caused by leakage, reducing equipment operating costs and maintenance difficulty, and extending the service life of the equipment.

One side of the sealing gasket 201 contacts the pump cover 202 for subsequent disassembly and maintenance of the slurry pump 1. A sealing rod 203 and a sealing cylinder 204 are respectively connected to the pump cover 202, the slurry pump 1, and the sealing gasket 201 to fix the pump cover 202, the slurry pump 1, and the sealing gasket 201 and improve the tightness. The inner wall of the sealing cylinder 204 is threadedly connected to one end of the sealing rod 203.

[0027] The surface of the slurry pump 1 is provided with a support base 7 for supporting the slurry pump 1. An auxiliary cover 8 is installed on the support base 7 to help fix the slurry pump 1.

[0028] Example 2:

[0029] like Figures 1-2 , Figures 4-5 As shown in the figure, according to an embodiment of the present invention, a quick-detachable slurry pump sealing structure is provided on the pump cover 202 and the slurry pump 1. The sealing component 2 3 includes a sealing gasket 2 301 on the pump cover 202 and the slurry pump 1, which is used to improve the sealing performance at the conveying and output points of the slurry pump 1. The sealing gasket 2 301 and the sealing gasket 201 are made of materials such as corrosion-resistant rubber, polytetrafluoroethylene, or other materials, which are existing technologies and will not be described in detail. The sealing gasket 2 301 and the slurry pump 1 and the pump cover 202 are provided with two symmetrically arranged sealing caps 302. To improve the tightness between the slurry pump 1's conveying and output points and the sealing seat 5, one end of the sealing cover 302 is hinged by a rotating shaft, and the other end of the sealing cover 302 is provided with an auxiliary groove. A rotating rod 303 is connected to the inner wall of one of the auxiliary grooves for rotating the limiting rod 304. The rotating rod 303 is threadedly connected to the limiting rod 304 on one of the sealing covers 302 to improve the sealing performance between the two sealing covers 302. Anti-slip sleeves 6 are provided on the limiting rod 304 and the sealing rod 203, and the anti-slip sleeves 6 are adapted to the limiting rod 304 and the sealing rod 203.

[0030] Both sides of the sealing gasket 201 and the sealing gasket 101 are provided with equally spaced snap-fit ​​blocks 4 to improve the stability of the sealing gasket 201 and the sealing gasket 101.

Then, the sealing rod 203 passes through the pump cover 202 and the sealing gasket 201, and is screwed into the sealing cylinder 204 and tightened to press the pump cover 202 and the sealing gasket 201 together to form a seal.

[0033] A second sealing gasket 301 is placed at the delivery / output interface of the slurry pump 1, and its position is fixed by its snap-fit ​​block 4. The sealing seat 5 is snapped onto the snap-fit ​​block 4 of the second sealing gasket 301. The two symmetrical sealing covers 302 are closed to cover the interface, the second sealing gasket 301 and the sealing seat 5. The limiting rod 304 is rotated to tighten it, so that the sealing cover 302 presses the sealing seat 5 and the sealing structure below.
