Description

Technical Field

[0001] This application relates to the field of ball mill technology, and in particular to a protective cylinder liner. Background Technology

[0002] A ball mill is a key piece of equipment used to further pulverize materials after they have been crushed. It is suitable for grinding various ores and other materials and is widely used in mineral processing, building materials, and chemical industries. A ball mill consists of main parts such as a feeding section, a discharging section, a rotating section, and a transmission section. The liner inside the ball mill cylinder protects the inner wall of the cylinder from direct impact and friction between the grinding media and the materials. Different types of liners can also be used to adjust the movement of the grinding media, enhancing their pulverizing effect on the materials and improving the grinding efficiency and output of the ball mill.

[0003] A search revealed a patent document with authorization announcement number CN212092560U, which discloses a protective and wear-resistant ball mill cylinder inner liner structure. The structure includes a cylinder, locking bolts, and an mounting groove. A fixing block is welded to the inner wall of the cylinder. A connecting rod is fixed to the other end of a return spring, and a liner is fixedly installed at the end of the connecting rod. Locking bolts penetrate the edge of the liner, and a protective block is fitted around the outside of the locking bolts. A connecting plate is installed on one side of the liner, and a fixing groove is pre-reserved inside the connecting plate. A movable block is movably installed inside the fixing groove, and the end of the movable block is connected to the fixing groove via a compression spring. An mounting groove is provided on the other side of the liner, and a limit groove is provided on the side of the mounting groove. This protective and wear-resistant ball mill cylinder inner liner structure allows for the replacement of a portion of the liner after partial damage, and the liner has good buffering performance, thus extending the service life of the mill.

[0004] In practical use, it was found that the existing cylinder liner has poor buffering and sealing performance, which leads to a rapid decline in the service life of the liner after long-term use, thus affecting the service life of the liner. Therefore, we proposed a cylinder liner with protective function to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing cylindrical liners, which have poor buffering and sealing performance, resulting in a rapid decline in the service life of the liner after long-term use, and thus affecting the service life of the liner. Therefore, this application proposes a cylindrical liner with protective function.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a cylindrical liner with protective function, comprising a cylindrical liner, an mounting plate provided on the right side of the cylindrical liner, an mounting mechanism provided on the mounting plate, a buffer cylinder fixedly mounted on the left side of the mounting plate, a buffer mechanism provided on the buffer cylinder; an airbag mechanism provided between the mounting plate and the cylindrical liner, and a sealing mechanism provided on the outside of the mounting plate.

[0007] A further feature of this application is that a sealing gasket is provided on the right side of the mounting plate, and the sealing gasket is adapted to the inner wall of the cylinder.

[0008] By adopting the above technical solution and by setting a sealing gasket, the sealing gasket can be tightly attached to the inner wall of the cylinder, thereby achieving a preliminary sealing effect and preventing material leakage.

[0009] A further feature of this application is that buffer strips are provided at the top and bottom of the right side of the cylinder liner, and the right side of the buffer strips is fixedly connected to the left side of the mounting plate.

[0010] By adopting the above technical solution and by setting up a buffer strip, the buffer strip can buffer part of the impact energy, thereby reducing the direct impact on the cylinder liner and cylinder.

[0011] A further feature of this application is that the installation mechanism includes bolts and nuts, the mounting plate sealing gasket is fixedly connected to the cylinder synchronous bolts, and the bolts are threaded with nuts.

[0012] By adopting the above technical solution and by setting up an installation mechanism, the cylinder liner can be installed and fixed to the cylinder by bolts and nuts.

[0013] A further feature of this application is that the sealing mechanism includes a sealing seat and a sealing ring, the sealing seat and the sealing ring are fitted onto the bolt, the sealing seat is located on the left side of the nut, the sealing ring is located on the left side of the sealing seat, and the sealing ring is adapted to the cylinder.

[0014] By adopting the above technical solution and setting a sealing mechanism, the sealing effect can be further enhanced by the sealing ring, preventing liquids, gases or fine materials inside the cylinder from leaking out from the bolts, thus ensuring the stability of the internal environment of the cylinder.

[0015] A further configuration of this application is as follows: the buffer mechanism includes a support column, a sliding plate, and a spring. The support column is slidably installed on the left side of the buffer cylinder, and the right end of the support column extends into the buffer cylinder. The left end of the support column is fixedly connected to the right side of the cylinder liner. The sliding plate is slidably installed inside the buffer cylinder, and the same spring is fixedly installed on the right side of the sliding plate and the right inner wall of the buffer cylinder.

[0016] By adopting the above technical solution and setting a buffer mechanism, the impact energy can be converted into elastic potential energy and stored by the spring, and then slowly released. This effectively reduces the impact force on the cylinder liner, protects its structural integrity, and avoids damage due to frequent impacts.

[0017] A further configuration of this application is as follows: the airbag mechanism includes an airbag and a vent pipe, the same airbag is provided between the mounting plate and the cylinder liner, the same vent pipe is provided between the airbag and the corresponding buffer cylinder, and the vent pipe is located on the right side of the slide plate.

[0018] By adopting the above technical solution and by setting up an airbag mechanism, the elastic force generated by the expansion of the airbag further buffers the relative displacement between the cylinder liner and the mounting plate, disperses the impact force, and at the same time fills the gap that may be caused by the impact to a certain extent, thereby achieving the purpose of enhancing the stability of the overall structure.

[0019] A further feature of this application is that the cylindrical liner has a through hole, which is adapted to fit a bolt.

[0020] By adopting the above technical solution, and by providing through holes, bolts can be passed through the through holes to install the mounting plate.

[0021] The beneficial effects of this application are:

[0022] (1) By using bolts and nuts, the mounting plate and sealing gasket can be fixedly installed, and the cylinder liner can be fixedly installed. By using sealing gaskets and sealing rings, the sealing effect of the cylinder can be enhanced, preventing liquid, gas or fine materials inside the cylinder from seeping out from the bolts, and ensuring the stability of the internal environment of the cylinder.

[0023] (2) Through the cooperation of support column, buffer cylinder and spring, the spring can convert the impact energy into elastic potential energy and store it, and then release it slowly. This can effectively reduce the impact force on the cylinder liner, protect its structural integrity, and avoid damage due to frequent impacts.

[0024] (3) Through the cooperation of the vent pipe and the airbag, when the slide plate slides to the right to compress the spring, the airbag can expand. The elastic force generated by the expansion of the airbag can further buffer the relative displacement between the cylinder liner and the mounting plate, disperse the impact force, and at the same time fill the gap between the two that may be caused by the impact to a certain extent, enhance the stability of the overall structure, and achieve the purpose of ensuring the cylinder liner can operate stably for a long time under complex working conditions. In this way, the buffering performance of the cylinder liner can be improved and the service life can be extended. Attached Figure Description

[0031] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] See Figures 1-4 This application provides a protective cylindrical liner, including a cylindrical liner 1, an mounting plate 2 on the right side of the cylindrical liner 1, an mounting mechanism on the mounting plate 2, a buffer cylinder 4 fixedly mounted on the left side of the mounting plate 2, a buffer mechanism on the buffer cylinder 4, an airbag mechanism between the mounting plate 2 and the cylindrical liner 1, and a sealing mechanism on the outside of the mounting plate 2.

[0033] Specifically, a sealing gasket 3 is provided on the right side of the mounting plate 2, and the sealing gasket 3 is adapted to the inner wall of the cylinder.

[0034] Specifically, buffer strips 5 are provided on the top and bottom right sides of the cylinder liner 1, and the right side of the buffer strips 5 is fixedly connected to the left side of the mounting plate 2.

[0035] Specifically, the installation mechanism includes bolts 201 and nuts 202. The sealing gasket 3 of the mounting plate 2 is fixedly connected to the synchronous bolts 201 of the cylinder, and the nuts 202 are threaded on the bolts 201.

[0036] Specifically, the sealing mechanism includes a sealing seat 203 and a sealing ring 204. The sealing seat 203 and the sealing ring 204 are fitted onto the bolt 201. The sealing seat 203 is located to the left of the nut 202, and the sealing ring 204 is located to the left of the sealing seat 203. The sealing ring 204 is adapted to the cylinder.

[0037] Specifically, the buffer mechanism includes a support column 401, a sliding plate 402, and a spring 403. The support column 401 is slidably installed on the left side of the buffer cylinder 4, and the right end of the support column 401 extends into the buffer cylinder 4. The left end of the support column 401 is fixedly connected to the right side of the cylinder liner 1. The sliding plate 402 is slidably installed inside the buffer cylinder 4, and the same spring 403 is fixedly installed on the right side of the sliding plate 402 and the right inner wall of the buffer cylinder 4.

[0038] Specifically, the airbag mechanism includes an airbag 101 and a vent pipe 102. The same airbag 101 is provided between the mounting plate 2 and the cylinder liner 1, and the same vent pipe 102 is provided between the airbag 101 and the corresponding buffer cylinder 4. The vent pipe 102 is located on the right side of the slide plate 402.

[0039] Specifically, the cylinder liner 1 has a through hole 6, which is compatible with the bolt 201.

[0040] In this application, during installation, the cylinder liner 1 is fixed to the inner wall of the cylinder by the installation mechanism. The sealing gasket 3 on the right side of the installation plate 2 is tightly fitted to the inner wall of the cylinder, which can achieve a preliminary sealing effect and prevent material leakage. The bolt 201 passes through the through hole 6 on the cylinder liner 1, the sealing gasket 3 and the cylinder, and is then tightened by the nut 202 to achieve a firm installation. The sealing seat 203 and the sealing ring 204 are fitted on the bolt 201 to further enhance the sealing effect and prevent liquid, gas or fine materials inside the cylinder from seeping out from the bolt 201, thus ensuring the stability of the internal environment of the cylinder.

[0041] During operation, when the cylinder liner 1 is subjected to external impact or vibration, the buffer mechanism plays a crucial role. The buffer strip 5 on the right side of the cylinder liner 1 comes into contact with the impact force first. The buffer strip 5 is made of elastic material, which can initially buffer part of the impact energy and reduce the direct impact on the cylinder liner 1 and the cylinder. At the same time, the support column 401 inside the buffer cylinder 4 is connected to the cylinder liner 1. When the impact force is transmitted, the support column 401 pushes the sliding plate 402 to the right and slides inside the buffer cylinder 4, compressing the spring 403. The spring 403 undergoes elastic deformation under force, converting the impact energy into elastic potential energy and storing it. Then it is slowly released, which can effectively reduce the impact force on the cylinder liner 1, protect its structural integrity, and avoid damage due to frequent impacts.

[0042] The airbag mechanism provides additional cushioning and protection for the cylinder liner 1. When the slide plate 402 inside the buffer cylinder 4 slides to the right to compress the spring 403, it will squeeze the air inside the buffer cylinder 4. The air enters the airbag 101 through the vent pipe 102, causing the airbag 101 to expand. The elastic force generated by the expansion of the airbag 101 can further buffer the relative displacement between the cylinder liner 1 and the mounting plate 2, disperse the impact force, and at the same time fill the gap that may be caused by the impact to a certain extent, enhance the stability of the overall structure, and achieve the purpose of ensuring that the cylinder liner 1 can operate stably for a long time under complex working conditions. In this way, it can improve the cushioning performance of the cylinder liner 1 and extend its service life.
