Description

Technical Field

[0001] The utility model belongs to the technical field of leather cups, in particular to a wear-resistant leather cup for sewage treatment. Background Art

[0002] In the sewage treatment system, sewage pumps are equipment that plays a vital role. They are responsible for pumping sewage from sewage collection tanks or sewage tanks to subsequent treatment equipment, such as screens, grit chambers, etc., to ensure that sewage is effectively treated. In sewage pumps, the piston core is a key component, and in order to reduce the friction between the piston core and the pump body, it is usually necessary to install a leather cup on the piston core as a seal. The role of the leather cup is to ensure the sealing inside the pump, prevent the sewage in the pump from leaking out, and reduce the energy consumption of the pump.

[0003] However, since the piston needs to perform frequent reciprocating motion during operation, this will cause the leather cup to be subjected to greater friction and wear during the reciprocating motion, thereby reducing the service life of the leather cup. Utility Model Content

[0004] The utility model aims at solving the problems existing in the prior art and proposes the following technical solutions:

[0005] Wear-resistant leather cups for sewage treatment, including:

[0006] The leather cup body comprises a sealing portion and a cup bottom;

[0007] A wear-resistant layer, wherein the sealing portion comprises a wear-resistant layer;

[0008] A replacement layer is provided on the outside of the wear-resistant layer.

[0009] As a preferred embodiment of the above technical solution, an inflation cavity is provided in an annular shape inside the wear-resistant layer, a ball is provided in the replacement layer, an airbag is installed on the inner side wall of the replacement layer, and the airbag is connected to the inflation cavity through an air inlet channel.

[0010] As a preferred embodiment of the above technical solution, two balls are evenly and movably embedded in the replacement layer, and two airbags are installed at the position of the inner wall of the replacement layer corresponding to the two balls. The two airbags are connected to the inflation chamber through an air inlet channel.

[0011] As a preferred embodiment of the above technical solution, wear-resistant whiskers are evenly arranged on the periphery of the replacement layer and the periphery of part of the wear-resistant layer.

[0012] As a preferred embodiment of the above technical solution, the wear-resistant layer is provided with a bent reinforcing plate in an annular shape.

[0013] As a preferred embodiment of the above technical solution, reinforcing ribs are provided at the bending parts of the reinforcing plate.

[0014] As a preferred embodiment of the above technical solution, the top diameter of the leather cup body is larger than the bottom diameter thereof.

[0015] The beneficial effects of the utility model are:

[0016] The utility model is provided with a replacement layer and wear-resistant whiskers. In the initial stage of using the leather cup, the replacement layer and the wear-resistant whiskers first contact with the inner wall of the pump body, so that the replacement layer and the wear-resistant whiskers are subjected to friction first. The wear-resistant layer formally plays a role only after the replacement layer and the wear-resistant whiskers are completely worn, thereby extending the service life of the leather cup;

[0017] The utility model is provided with ball one, ball two, airbag one, airbag two and an inflation chamber. Ball one takes effect after the replacement layer is worn. Airbag one is used to inflate the inflation chamber, so that the corresponding position of the wear-resistant layer expands, thereby improving the sealing and stability of the wear-resistant layer. Ball two effectively reduces the friction between the replacement layer and the wear-resistant layer and the inner wall of the pump body during normal use, reduces wear and prolongs the service life of the leather cup. At the same time, airbag two is squeezed erratically to inflate the inflation chamber, thereby improving the sealing of the wear-resistant layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1-3 As shown;

[0026] The wear-resistant leather cup for sewage treatment includes a leather cup body 1, which is composed of a sealing part 2 and a bowl bottom 3. A through hole 4 is provided on the bowl bottom 3, and the leather cup body 1 is installed on the piston by passing the piston core through the through hole 4 to ensure the sealing of the pump. The sealing part 2 includes a wear-resistant layer 21, and the wear-resistant layer 21 is mainly in contact with the inner wall of the pump body, and a replacement layer 22 is provided on the outer side of the wear-resistant layer 21, and the replacement layer 22 is located outside the wear-resistant layer 21. In the early stage of using the leather cup, the inner wall of the pump body first contacts the replacement layer 22, so that the replacement layer 22 is subjected to friction first, and the wear-resistant layer 21 is not formally effective until the replacement layer 22 is completely worn, thereby extending the service life of the leather cup. This leather cup is made of nitrile rubber material, has good wear resistance, and can effectively improve the wear resistance and service life of the leather cup. Through this design, the leather cup in the sewage treatment system can work more durable and stably, thereby ensuring the normal operation and long-term use of the sewage pump equipment. This provides important guarantees for the reliability and efficiency of the sewage treatment system, while also reducing maintenance costs and the need for frequent replacement of components, allowing the sewage treatment system to operate more economically and efficiently;

[0027] Furthermore, an inflatable cavity 211 is provided in an annular shape inside the wear-resistant layer 21, and this design helps to increase the elasticity and wear resistance of the leather cup. A ball 221 is provided inside the replacement layer 22, and the function of the ball 221 is to gradually appear when the replacement layer 22 is worn, and to reduce the degree of wear of the replacement layer 22 by rolling, thereby extending the service life of the replacement layer 22. In addition, an airbag 223 is installed on the inner wall of the replacement layer 22, and the airbag 223 is connected to the inflatable cavity 211 through the air inlet channel 212, so that the airbag can be inflated as needed, thereby adjusting the sealing and stability of the leather cup;

[0028] When the replacement layer 22 is gradually worn, the ball 221 will gradually appear and begin to play a role. The rolling of the ball 221 can effectively reduce the wear rate of the replacement layer 22 and extend its service life. When the replacement layer 22 is worn to the point where the wear-resistant layer 21 contacts the inner wall of the pump body, the ball 221 will begin to squeeze the airbag 223 and inflate the inflation chamber 211 through the air inlet channel 212, causing the corresponding position of the wear-resistant layer 21 to expand, thereby improving the sealing and stability of the wear-resistant layer 21 and ensuring the normal operation and long-term stable operation of the pump. This not only improves the wear resistance and service life of the leather cup, but also enhances its adaptability and performance.

[0029] Furthermore, the replacement layer 22 is evenly and movably inlaid with a second ball 222, which helps to further reduce the friction between the replacement layer 22 and the inner wall of the pump body, and improve the wear resistance and stability of the leather cup. A second airbag 224 is installed at the position of the inner wall of the replacement layer 22 corresponding to the second ball 222, and the second airbag 224 is also connected to the inflation chamber 211 through the air inlet channel 212;

[0030] During normal use of the leather cup, in addition to the contact between the replacement layer 22 and the wear-resistant layer 21 and the inner wall of the pump body, the second ball 222 will also contact the inner wall of the pump body. When the leather cup moves back and forth, the second ball 222 can effectively reduce the friction between the replacement layer 22 and the wear-resistant layer 21 and the inner wall of the pump body, reduce wear, and extend the service life of the leather cup. This not only improves the wear resistance and stability of the leather cup, but also further optimizes the matching effect between the leather cup and the pump body, ensuring the efficient operation and long-term stable operation of the pump equipment.

[0031] like Figure 3 As shown;

[0032] Wear-resistant whiskers 23 are evenly arranged on the periphery of the replacement layer 22 and part of the periphery of the wear-resistant layer 21. When in use, the wear-resistant whiskers 23 are located on the outside of the replacement layer 22 and the wear-resistant layer 21, and first contact the inner wall of the pump body, which can reduce the friction between the replacement layer 22 and the wear-resistant layer 21 and the inner wall of the pump body, thereby increasing the service life of the leather cup; at the same time, it can also improve the sealing effect of the leather cup when in use.

[0033] like Figure 2 As shown;

[0034] The wear-resistant layer 21 is provided with a bent reinforcing plate 5 in an annular shape, and a reinforcing rib 51 is provided at the bending part of the reinforcing plate 5. The reinforcing plate 5 and the reinforcing rib 51 improve the overall strength of the leather cup, and at the same time improve the stability of the leather cup during the reciprocating movement, the wear resistance of the leather cup is further improved.

[0035] like Figure 2 As shown;

[0036] The top diameter of the leather cup body 1 is larger than its bottom diameter, so that the outer top of the sealing part 2 is always in contact with the inner wall of the pump body. In conjunction with the reinforcing plate 5, the sealing part 2 always has a tendency to expand outward. The sealing part 2 is set to a corresponding thickness, so that the sealing part 2 can be used until it is worn to the point where the sealing performance can no longer be ensured, thereby indirectly increasing the service life of the leather cup while ensuring its sealing performance.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
