Description

A wear-resistant and detachable ball press roller

technical field

The utility model relates to the technical field of cold-pressed pellet processing, in particular to a wear-resistant and detachable pressing roller of a ball press.

Background technique

In the production of cold-pressed pellets, the briquette machine is mainly used for pressing powdery materials that are difficult to form, such as coal powder, iron powder, aluminum powder, slag and other powders and wastes. It is sent to the rollers of the double-roller high pressure briquetting machine for rolling. Since many ball sockets are made on the surface of the rollers, the mixture can be pressed into pellets after passing through the rollers. The finished balls formed by the briquetting machine have high strength, convenient transportation, energy saving and environmental protection, improve the utilization rate of waste materials, and have good economic and social benefits. The main structure of the briquetting machine includes the feeding part, the transmission part and the forming part. Among them, the feeding part mainly realizes quantitative feeding to ensure that the material enters the pair of rollers evenly; the transmission part is generally composed of a motor, a triangular belt, a reducer, an open gear, and a pressure roller; the forming part mainly refers to the host part, and the core part is Pressure roller. The briquetting roller is the most important part of the roller briquetting machine, and it is also the part with severe working conditions and serious wear, which requires frequent maintenance and replacement. The structure of the briquetting roller includes: integral type; hub type; composite type.

The integral type is for the larger briquetting roller, which is made of the same material as a whole, which wastes the material and makes casting and heat treatment difficult. Generally, it is rarely used. The wheel hub type is currently the most widely used one, but there are also defects such as looseness that are prone to occur when the hub part is cast, and cracks are prone to occur due to uneven shrinkage during heat treatment. The composite type is to add a wear-resistant outer ring on the basis of the hub type, but how to form a good fit between the inner and outer rings is the key. Generally, a micro-pass win or a low melting point metal is poured into the gap between the inner and outer rings, but it will make assembly and disassembly. It is difficult, and it is generally difficult to implement in the production site; and the spherical size of the ball socket of the ball pressing roller and the unreasonable selection of the depth are easy to cause difficulty in demoulding, and there is a cavity failure, which will affect normal production.

The effect of the solution is that the clamping seat and the fixing seat can be easily clamped or separated by bolts, so as to realize the convenience of assembly.

Preferably, a plurality of sliding grooves are axially opened on the outer ring surface of the inner ring seat, sliding blocks are slidably installed in the sliding grooves, and the sliding blocks are fixedly connected to the inner ring surface of the outer ring seat , the fixed seat is fixedly connected with the end face of the inner ring seat.

The effect of this solution is to improve the stability of the outer ring seat when sliding along the length direction of the inner ring seat, and to prevent relative rotation between the outer ring seat and the inner ring seat during the rotation process.

Preferably, there are eight said sliding grooves, and the eight said sliding grooves are evenly arranged on the outer ring surface of the inner ring seat, and the length of the sliding block is the same as that of the sliding grooves.

The effect of this solution is to further improve the stability of axial sliding and the stability during rotation.

Preferably, the cross-sectional shape of the ball socket along the axial direction of the roller sleeve is an inverted water drop shape formed by opposite involutes, and the shape of the mouth of the ball socket is an oval.

The effect of this solution is that the demolding pressure can be used to achieve efficient demolding of the pellets.

Preferably, the size of the ball socket is 35-45mm in length, 28-35mm in width, and 6-15mm in depth.

The effect of this scheme is to expand the adaptability to raw materials and improve the versatility of the briquetting machine.

Beneficial effects: Compared with the prior art, the wear-resistant and detachable ball press roller provided by the utility model completely avoids casting defects and heat treatment cracks from the structure, and the ball press roller is more convenient to assemble and disassemble , which can effectively avoid the axial movement and relative rotation between the roller sleeve and the roller shaft, and can also rely on the pressure of the briquetting machine itself to achieve demoulding, achieve efficient demoulding of the pellets, and reduce the size and depth of the ball socket. The influence coefficient of demoulding greatly improves the versatility of the briquetting machine.
