Description

Technical Field

[0001] This utility model relates to the technical field of suspension roller mills, specifically a segmented liner plate for suspension roller mills. Background Technology

[0002] The suspension roller mill is a device that uses a motor to drive a central shaft and a perforated frame to make the grinding rollers rotate around a grinding ring. The centrifugal force of the grinding rollers is used to press the grinding ring tightly, squeezing, grinding and shearing the material falling into the grinding chamber. The crushed material is then classified by a classifier, and the fine powder is collected by a dust collector as the finished product.

[0003] During the operation of a suspension roller mill, the liner, as a key component that directly contacts the material, is subjected to intense compression, grinding, and friction over a long period of time, leading to a significantly accelerated wear rate. Currently, most suspension roller mills on the market use an integrated liner structure, which, while providing strong integrity, reveals obvious drawbacks when wear and replacement are required. Due to its non-separable nature, maintenance personnel must disassemble the entire liner, which is not only time-consuming and labor-intensive but also requires specialized tools and personnel. Furthermore, the external impact during disassembly may damage other components of the mill, greatly affecting equipment maintenance efficiency and production continuity. Therefore, we propose a segmented liner for suspension roller mills. Utility Model Content

[0004] The purpose of this utility model is to provide a segmented liner for a suspension roller mill, thereby solving the problem mentioned in the background art that most suspension roller mills on the market use an integrated liner structure, requiring maintenance personnel to disassemble the entire liner. To achieve the above objective, this utility model provides the following technical solution: a segmented liner for a suspension roller mill, comprising a base;

[0005] A liner assembly, comprising a plurality of liner bodies, the plurality of liner bodies being movably connected inside the base and arranged in a circular array, wherein a connecting block is fixedly connected to one side of each of the plurality of liner bodies, a locking block is fixedly connected to the bottom of the connecting block, and a sealing gasket is fixedly connected to the opposite side of the locking block.

[0006] The installation assembly includes several connecting blocks 2, which are fixedly connected to the inside of the base and arranged in a circular array. The top of each connecting block 2 is movably connected to the bottom of a connecting block 1. When using the device, the operator only needs to insert the liner body into the pre-set disassembly and assembly slots on the base, so that the connecting block 1 at the bottom of the liner body is precisely engaged with the top of the connecting block 2 on the base, thus quickly completing the installation and ensuring efficient contact between the liner and the material in the grinding chamber. When the liner body is severely worn due to long-term grinding, the operator only needs to unscrew the fixing bolt 1 to quickly release the fastening connection between the liner and the base, easily removing and replacing the single worn liner from the base. This modular design not only greatly simplifies the disassembly and assembly steps but also avoids the cumbersome process of disassembling the entire traditional integrated liner.

[0007] More preferably, the base is provided with an installation component inside, and the installation component further includes a plurality of slots, which are respectively opened on the top of the connecting block two, and the inside of the slots is adapted to the outside of the block and the sealing gasket.

[0008] More preferably, the base has several mounting slots at its bottom, which are arranged in a circular array. Each of the mounting slots is fitted with a fixing bolt. The top of the fixing bolt is fixedly connected to the bottom of the liner body. The base is provided with a connecting component.

[0009] More preferably, the connecting assembly includes a first mounting ring, which is fixedly connected to the bottom of the base, and a vertical bearing seat is sleeved inside the first mounting ring. A second mounting ring is fixedly connected to the side surface of the vertical bearing seat.

[0010] More preferably, the bottom of the second mounting ring and the first mounting ring are respectively provided with a plurality of second mounting grooves, and the plurality of second mounting grooves are arranged in a ring array. The interior of each of the plurality of second mounting grooves is fitted with a second fixing bolt. The top of the second fixing bolt is fixedly connected to the bottom of the liner body. The side surface of the base is provided with a disassembly and assembly assembly.

[0011] More preferably, the disassembly and assembly assembly includes a plurality of disassembly and assembly slots, which are formed on the side surface of the base and are arranged in a circular array. Each of the disassembly and assembly slots is movably connected to a baffle, and each of the baffles is fixedly connected to a fixing plate on the opposite side.

[0012] In a further preferred embodiment, the side surfaces of the fixing plate and the base are respectively provided with a plurality of threaded grooves, and the internal threads of the plurality of threaded grooves are connected with fixing bolts, which can remove and replace the liner plates in different areas, effectively improving the convenience of the device.

[0013] More preferably, the top of the base is provided with a connecting groove, and the interior of the connecting groove is provided with a grinding chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when using the device, the operator only needs to insert the liner body into the pre-set disassembly and assembly slots of the base in sequence, so that the connecting block one at the bottom of the liner body is precisely engaged with the top of the connecting block two of the base, and the installation can be completed quickly, ensuring efficient contact between the liner and the material in the grinding chamber. When the liner body is severely worn due to long-term grinding, the operator only needs to unscrew the fixing bolt one to quickly release the fastening connection between the liner and the base, and easily remove and replace the single worn liner from the base. This modular design not only greatly simplifies the disassembly and assembly steps, but also avoids the cumbersome process of disassembling the entire traditional integrated liner.

[0016] In this utility model, when using the device, the operator can remove the fixing bolt three, so that the fixing connection between the disassembly groove, the baffle, and the fixing plate can be released. This allows the operator to remove the baffle and the fixing plate from the outside of the base, and then remove and replace the liner body from the inside of the base. This allows for the removal and replacement of the liner in different areas, effectively improving the convenience of the device. Attached Figure Description

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the base 1 has an internal mounting assembly 3, which includes several slots 302. These slots 302 are respectively located on the top of the connecting block 201. The interior of each slot 302 is adapted to the outer sides of the block 203 and the sealing gasket 204. The bottom of the base 1 has several mounting grooves 303 arranged in a circular array. Fixing bolts 304 are fitted inside each mounting groove 303, with the tops of the bolts 304 fixedly connected to the bottom of the liner body 201. The base 1 also has an internal connecting assembly 4, which includes a mounting ring 401 fixedly connected to the bottom of the base 1. A vertical bearing seat 4 is fitted inside the mounting ring 401. 02. A mounting ring 403 is fixedly connected to the side surface of the vertical bearing seat 402. The bottom of the mounting ring 403 and the mounting ring 401 are respectively provided with a number of mounting grooves 404, which are arranged in a ring array. Fixing bolts 405 are respectively fitted inside the mounting grooves 404. The top of the fixing bolts 405 is fixedly connected to the bottom of the liner body 201. The side surface of the base 1 is provided with a disassembly assembly 5.
