Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of anti-sticking wear-resistant impact-resistant composite lining, belong to rubber belt machine transport transfer equipment field. BACKGROUND

[0002] In order to prevent equipment body abrasion and improve service life in mineral rubber belt machine conveying system, wear-resistant lining is set at the position where material flows. The material of wear-resistant lining currently used mainly includes stainless steel, high-chromium cast iron, ceramic and ultra-high molecular polyethylene plate. Although stainless steel and high-chromium cast iron have strong impact resistance, they have poor wear resistance. Ceramic lining has good wear resistance, but ceramic is a brittle material, which is easy to break under the impact of large material, and has short service life. Especially when the drop of transported material in conveying system is larger, the damage of ceramic lining is greater.

[0003] In most scenarios of belt machine transporting mineral material, the transported mineral material is not single powder, granular, spherical or blocky. Different shape, particle size, material, composition, grade and moisture content of mineral material have different requirements for the lining of chute. Powdered mineral material and mineral material with high moisture content require lining to be smooth and not sticky, and wear-resistant. Granular, spherical and blocky material requires lining to be impact-resistant and wear-resistant. For some special powder material, such as vanadium-titanium magnetite iron concentrate, it has the characteristics of fine particles, high moisture content and magnetism. When this powder material passes through the chute with iron lining and rough lining, it is easy to cause the lining to stick and block the chute.

[0004] In summary, the lining of chute in mineral belt machine conveying system transfer needs to have strong impact resistance and wear resistance, and also needs to have the characteristics of not sticking and easy to slide. INVENTION CONTENTS

[0005] The technical problem to be solved by the utility model is that the existing ceramic lining is easy to be damaged by high-drop material impact, and has poor vibration cleaning effect.

[0006] The utility model adopts the technical scheme to solve the technical problem: the anti-sticking wear-resistant impact-resistant composite lining, comprising a mounting plate and a ceramic column, further comprising a buffer layer, the buffer layer is arranged on the mounting plate, the lower end of the ceramic column is provided with a buffer impact part, so that the ceramic column has a structure of small at the top and large at the bottom, the ceramic columns are arranged in the buffer layer at intervals, and the contact surface between the buffer impact part and the buffer layer is arc-shaped.

[0007] In the above structure, the buffer layer is made of rubber or flexible polyurethane.

[0008] In the above structure, the distance between the lower end of the ceramic column and the lower end of the mounting plate is 1-20 mm.

[0009] The distance between the adjacent ceramic columns in the structure is 1-25mm.

[0010] The ceramic column in the structure is coplanar with the upper end surface of the buffer layer.

[0011] The slow-release impact part is a spherical segment structure, and the small end is connected with the end of the ceramic column.

[0012] The slow-release impact part is a spherical structure.

[0013] The lower end of the mounting plate is provided with a connecting piece.

[0014] The upper part of the ceramic column is a cylindrical structure, and the adjacent ceramic columns are staggered.

[0015] The length of the ceramic column is 20-50mm, and the size of the widest part of the slow-release impact part is 1-3 times the width of the upper end of the ceramic column.

[0016] The beneficial effects of the utility model are as follows: the structure is provided with a slow-release impact part at the lower part of the ceramic column, so that the contact surface of the ceramic column and the buffer layer is an arc or spherical surface structure, and the ceramic column is suspendedly installed in the buffer layer in a casting-inlay mode; when the vibrating motor is cleaning, the slow-release impact part has the functions of attracting and amplifying the end surface vibration force, so that the purpose of indirectly removing the material on the small end of the ceramic column is achieved, and a large area of material sticking on the surface of the lining plate is avoided, and the pipe is prevented from being blocked due to accumulation. The ceramic column has a smaller volume and surface area than the traditional ceramic block, so that the impact resistance of the ceramic body to the large block is enhanced. Meanwhile, the combination of the ceramic column and the buffer layer makes the ceramic body have a rear elastic buffer, and the ceramic body no longer has a hard collision with the material; the single buffer layer has poor impact resistance and wear resistance, but the structure combines the two, so that the spherical body at the lower end of the ceramic column is in contact with the buffer layer through the arc surface without sharp angle and the contact area is increased, the impact force borne by the ceramic column is greatly released, the wear resistance of the surface of the lining plate is increased due to the design of the ceramic column, the ceramic column and the buffer layer have high density and low water absorption (the water absorption of the ceramic column and the buffer layer is less than or equal to 0.2), and the ceramic column and the buffer layer have no attraction to vanadium-titanium magnetite powder, so that the problem of easy material sticking is effectively solved. The mounting plate is arranged on the buffer layer to realize structure fixation and convenient installation. The structure has a wide range of applications, and can be used in the material transfer field of the chute, the hopper and other material transfer devices in various conveying systems of various metallurgical equipment, mine equipment, wharfs and port powder transfer equipment, so that the service life and operation efficiency of the equipment are greatly improved, the equipment maintenance cost and labor intensity of workers are reduced, and the structure has very important economic value and social significance.
