Description

A rubber block coarse crushing equipment

technical field

The invention belongs to the technical field of machinery manufacturing, and relates to a recycling and processing equipment for waste solids, in particular to a kind of solid waste solids made of about 50×50 mm through extrusion, rubbing, grinding, shearing and tearing. From large to small to powder and granules, it is convenient to recycle the equipment for further processing or direct use in the later stage.

Background technique

Under the background that the country vigorously advocates and supports resource recycling, people are more and more fully aware of the importance of resource recycling, so industries such as wood, rubber and plastic, waste tires and other large solid waste recycling and reuse industries have emerged.

In this industry, the waste tire rubber block shredder is an important equipment in the processing process. It usually uses a knife shearing method to crush the rubber block, and it must pass through two types of crushing equipment with different structure screens to complete the process from rubber block to rubber granule. processing,. That is, the rubber block is crushed into coarse rubber particles of about 12mm through coarse crushing, and then the 12mm rubber particles are crushed into small particles of about 4mm through fine crushing. The wear block requires uninterrupted disassembly of the tool to sharpen the edge. This production or production line structure is a bottleneck problem that is common in the industry and needs to be solved urgently. Furthermore, during the production process, the machine produces huge noise, which has a bad impact on the surrounding environment.

Contents of the invention

The purpose of the present invention is to provide a low-noise, low-speed, high-yield crushing equipment for the deficiencies of the existing equipment. The equipment uses fixed and moving knives to squeeze and shear the rubber block at a low speed, so that the rubber block can be crushed to In the process of the rubber particles of about 3mm, it only needs to be completed in one step on half the circumference of the crushing roller, that is, about 50mm of rubber blocks go in and about 3mm of rubber particles come out.

The present invention is realized through the following technical solutions: the present invention is mainly composed of a base, a body, a feeding hopper, a crushing roller and a fixed knife seat, etc., the body is fixed on the base, and the crushing roller is arranged in the body through the bearing seats at both ends thereof. The fixed knife seat in the shape of a garden arc is set on the base of the fixed knife seat in the machine body and covers one side of the crushing roller. The fixed knife seat base can be adjusted and moved along the radial direction of the crushing roller. A feed hopper is provided on the machine body above the connecting section, and a moving knife and a fixed knife are respectively provided on the crushing roller and the fixed knife seat.

Compared with the prior art, the present invention has a simple and ingenious structure, the crushed solids are gradually reduced from large to small, low energy consumption, high crushing efficiency, low speed and low noise, convenient maintenance, and the moving knife and fixed knife do not directly participate in cutting, and the cutting tool is used long life.

Detailed ways:

The present invention will be further described below in conjunction with specific drawings and embodiments.

As shown in Figures 1 to 6, the present invention is mainly composed of a base 4, a body 3, a feed hopper 1, a crushing roller 2 and a fixed knife seat 9, etc., the body 3 is fixed on the base 4, and the crushing roller 2 passes through the bearings at both ends. The seat is arranged in the body 3, and the fixed knife seat 9 in the shape of a garden arc is arranged on the fixed knife seat base 12 in the body 3, and is covered on one side of the crushing roller 2, and the fixed knife seat base adjustment mechanism 5, 12 can be moved along the The radial direction of the crushing roller 2 is adjusted and moved, and a feeding hopper 1 is arranged on the body 3 above the connecting section of the crushing roller 2 and the fixed knife seat 9, and the crushing roller 2 and the fixed knife seat 9 are respectively provided with a movable knife 11 and a Stationary Knife10.

The moving knife 11 is compressed and fixed on the crushing roller 2 by the moving knife insert 14 or is surfacing welded on the crushing roller 2 .

The fixed knife 10 is installed on the inner circular arc of the fixed knife seat 9 by the fixed knife insert 13 or the surfacing welding alloy is on the inner circular arc of the fixed knife seat 9 .

Crushing roller 2 which is cooled by circulating water.

The fixed knife seat 9 is cooled by circulating water.

When processing waste tires, the rubber block of about 50mm is introduced from the feed hopper 1, and the rubber block is involved in the gap between the movable knife 11 and the fixed knife 10 with the rotation of the crushing roller 2, and the movable knife 11 and the fixed knife 10 work together, because the gap between the crushing roller 2 and the fixed knife seat 9 gradually becomes smaller, the rubber block is squeezed, rubbed, rolled, cut, and torn, and the rubber block is gradually crushed and becomes smaller as the moving knife moves downward. Small, the crushed colloidal particles are discharged from the lower end (tail) of the fixed knife seat 9.

And because the crushing roller 2 is driven by the reduction motor 8 to run at a low speed, the noise of the working environment is greatly reduced.

When it is necessary to adjust the gap between the crushing roller 2 and the fixed knife seat 9, the fixed knife seat 9 can be moved by adjusting the radial direction of the crushing roller 2 through the fixed knife seat base adjustment mechanism 5,12.

Because the pulverizing roller 2 and the fixed knife seat 9 are all cooled by circulating water, a large amount of heat generated in the processing process is taken away, which ensures the normal operation of the present invention.
