Description

Technical Field

[0001] This utility model belongs to the technical field of wear-resistant lining plates, and in particular relates to a cast lining plate with ceramic inlay. Background Technology

[0002] In material conveying systems of industries such as mining, steel, power, cement, non-ferrous metals, and chemicals, wear-resistant liners are installed at the points through which materials flow to prevent wear on the equipment body and extend its service life. Ceramic liners, in particular, are widely used due to their strong wear resistance.

[0003] For example, Chinese utility model CN211801317U discloses a cast ceramic inlay liner. By setting the mounting holes and mounting bases into a shape that gradually decreases from bottom to top, the base plate can hold the ceramic block in place after installation, preventing the ceramic block from falling off and improving the reliability of the liner.

[0004] However, in the aforementioned existing technology, if individual ceramic blocks are damaged, the base plate and the ceramic block as a whole need to be removed, a new ceramic block needs to be replaced, and finally the whole thing needs to be installed back on the equipment. This makes the replacement and disassembly process quite cumbersome, resulting in low overall replacement and maintenance efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a cast ceramic inlay liner plate, which inserts the ceramic column into the slot hole through the screw-in section at the lower end of the ceramic column, and the locking block is locked into the horizontal section by rotation, thereby limiting the axial position of the ceramic column. Disassembly can be performed by rotating in the opposite direction, which solves the problem of the cumbersome replacement and disassembly process of existing ceramic columns, resulting in low replacement and maintenance efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a cast ceramic inlay liner, comprising a mounting base plate and several ceramic columns. The mounting base plate has mounting holes evenly distributed on its upper surface, and slots are formed on the bottom surface of each mounting hole, creating a stepped blind hole structure between the slots and the mounting holes. Several screw-in slots are evenly distributed around the inner circumference of each slot, forming an L-shaped structure, including a vertical section and a horizontal section connected to the lower end of the vertical section. Each ceramic column includes a mounting section adapted to the mounting hole and a screw-in section adapted to the slot. A spherical protrusion is provided on the upper surface of the mounting section. A locking block, corresponding to a screw-in slot, is provided on the circumferential surface of the screw-in section. This allows the screw-in section to be inserted into the slot, with the locking block inserted along the vertical section. By rotating the ceramic column, the locking block engages with the horizontal section, thereby limiting the axial position of the ceramic column and achieving the connection between the ceramic column and the mounting base plate.

[0008] As a preferred technical solution of this utility model, a punched rubber washer is installed between the end face of the mounting section and the bottom surface of the mounting hole, which is used to apply elastic force to the end face of the mounting section through the punched rubber washer, thereby improving the stability of the connection between the ceramic column and the mounting base plate.

[0009] As a preferred embodiment of this utility model, an elastic gasket is provided between the inner bottom surface of the slot hole and the end face of the screw-in section.

[0010] As a preferred technical solution of this utility model, a limiting groove is provided on the top wall of the horizontal section, which is used to limit the rotation of the ceramic column in the circumferential direction by the upper end of the locking block cooperating with the limiting groove.

[0011] As a preferred embodiment of this utility model, the spherical surface protrudes into a hemispherical structure.

[0012] As a preferred technical solution of this utility model, the upper end face of the mounting section is provided with a plurality of strip-shaped protrusions, and the plurality of strip-shaped protrusions are arranged in an array along the circumference of the spherical protrusions.

[0013] In a preferred embodiment of this invention, the length direction of the strip-shaped protrusion coincides with the radius direction of the ceramic column.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model features mounting holes evenly distributed on the upper surface of the mounting base plate, with slot holes on the bottom surface of each mounting hole. Several L-shaped screw-in slots are evenly distributed around the inner circumference of each slot hole. By inserting the screw-in section of the ceramic column into the slot hole, the locking block is inserted along the vertical section. By rotating the ceramic column, the locking block is locked into the horizontal section, thereby limiting the axial position of the ceramic column and achieving the connection between the ceramic column and the mounting base plate, thus effectively improving the convenience of installation.

[0016] 2. By using the insertion and rotation mechanism between the slot hole and the locking block, during disassembly, simply rotate the ceramic column in the desired direction until the locking block aligns with the vertical section screwed into the slot, and the ceramic column can be pulled out without disassembling the mounting plate. This effectively improves the convenience of disassembling and replacing the ceramic column, greatly enhancing overall maintenance efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1 , 5 As shown in Figure 6, this utility model is a cast ceramic inlay liner, including a mounting base plate 1 and several ceramic columns 2. The upper surface of the mounting base plate 1 is evenly provided with mounting holes 101 and multiple connecting holes for connecting to the equipment by bolts.

[0032] A slot hole 102 is formed on the inner bottom surface of the mounting hole 101, and the inner diameter of the slot hole 102 is smaller than the inner diameter of the mounting hole 101, forming a stepped blind hole structure between the slot hole 102 and the mounting hole 101. Simultaneously, two to four screw-in slots 3 are evenly distributed around the inner circumference of the slot hole 102, as shown in the figure. The screw-in slots 3 have an L-shaped structure, including a vertical section 301 and a horizontal section 302 connected to the lower end of the vertical section 301. The upper end of the vertical section 301 penetrates the inner bottom surface of the mounting hole 101, and the vertical section 301 is formed along the circumferential direction of the inner wall of the slot hole 102.

[0033] like Figure 7 and 8 As shown, the ceramic column 2 includes a mounting section 201 adapted to the mounting hole 101 and a screw-in section 202 adapted to the slot hole 102, making the ceramic column 2 an overall stepped column structure. The upper end surface of the mounting section 201 is provided with a spherical protrusion 203, which is a hemispherical structure.

[0034] like Figures 2-4 As shown, the circumferential surface of the screw-in section 202 is provided with locking blocks 204 that correspond one-to-one with the screw-in slots 3. During installation, the screw-in section 202 at the lower end of the ceramic column 2 is inserted into the slot hole 102, so that the locking blocks 204 are inserted along the vertical section 301. When the ceramic column 2 can no longer be inserted, the ceramic column 2 is rotated, causing the locking blocks 204 to rotate and lock into the horizontal section 302. The horizontal section 302 limits the movement of the locking blocks 204 in the vertical direction, thereby limiting the axial position of the ceramic column 2 and realizing the connection between the ceramic column 2 and the mounting base plate 1.

[0035] When it is necessary to disassemble and replace the ceramic column 2, simply rotate the ceramic column 2 so that the locking block 204 rotates to the position corresponding to the vertical section 301. At this time, the ceramic column 2 can be pulled out directly without disassembling the installation base plate 1, which effectively improves the convenience of disassembling and replacing the ceramic column 2 and greatly improves the overall maintenance efficiency.

[0036] Among them, such as Figure 2 As shown, a punched rubber washer 4 is installed between the end face of the mounting section 201 and the inner bottom surface of the mounting hole 101. The punched rubber washer 4 can be pre-placed at the bottom of the mounting hole 101 or sleeved on the mounting section 201. Because the punched rubber washer 4 is installed, after the screw-in section 202 is inserted into the slot hole 102, the ceramic column 2 needs to be pressed down to deform the punched rubber washer 4 so that the locking block 204 corresponds to the position of the horizontal section 302. That is, only then can the ceramic column 2 be rotated so that the locking block 204 is locked into the horizontal section 302.

[0037] Because the deformation of the punched rubber gasket 4 has a certain rebound force, the punched rubber gasket 4 applies elastic force to the end face of the mounting section 201, which increases the friction between the locking block 204 and the inner top wall of the horizontal section 302, preventing the ceramic column 2 from rotating unexpectedly, thereby improving the stability of the connection between the ceramic column 2 and the mounting base plate 1.

[0038] Meanwhile, an elastic gasket 5 is installed between the inner bottom surface of the slot hole 102 and the end face of the screw-in section 202. The elastic gasket 5 can be a rubber gasket, and its function is the same as that of the stamped rubber washer 4. When the ceramic column 2 is installed, the elastic gasket 5 is deformed by the pressure of the end face of the screw-in section 202, thereby causing the elastic gasket 5 to apply an axial rebound force to the end face of the screw-in section 202. This, in conjunction with the stamped rubber washer 4, increases the axial force on the ceramic column 2, improving the stability of the ceramic column 2. It also provides a certain buffering effect for the impact received by the ceramic column 2.

[0039] like Figure 6 As shown, in another preferred embodiment, a limiting groove 303 is provided on the inner top wall of the horizontal section 302. Due to the upward rebound force of the punched rubber gasket 4 and the elastic pad 5 on the ceramic column 2, the locking block 204 is locked into the horizontal section 302. After the ceramic column 2 is released, the ceramic column 2 moves upward, so that the upper end of the locking block 204 is locked into the limiting groove 303. By the cooperation between the upper end of the locking block 204 and the limiting groove 303, the rotation of the ceramic column 2 in the circumferential direction is limited, so that the rotation of the ceramic column 2 in the circumferential direction is completely restricted, further ensuring the stability and reliability of the ceramic column 2 after installation.

[0040] Meanwhile, four to six strip-shaped protrusions 205 are provided on the upper surface of the mounting section 201, and the four to six strip-shaped protrusions 205 are arranged in a circular array along the circumference of the spherical protrusions 203. Furthermore, the length direction of the strip-shaped protrusions 205 coincides with the radial direction of the ceramic column 2, and the upper surface of the strip-shaped protrusions 205 is a curved structure, or the cross-section of the strip-shaped protrusions 205 is set as a semi-circular structure.

[0041] By adding strip protrusions 205, the rotation of the ceramic column 2 can be improved, and the residence time of the material at the position of the ceramic column 2 can also be increased. This allows the surface of the mounting base plate 1 and the ceramic column 2 to have a certain amount of material, which in turn can further reduce the wear on the surface of the mounting base plate 1 through the material layer, thus helping to improve the overall service life.
