Description

Waste tire recycling device

technical field

The invention relates to a waste tire recycling device for separating and recycling rubber and steel wire in waste tires.

Background technique

With the development of the automobile industry, the quantity of waste tires shows a rapid growth trend. At present, my country's annual production of waste tires reaches 130 million, ranking second in the world. The large amount of waste tires produced and the continuous growth of the total amount make tire disposal an industry of increasing concern. Especially the waste tires known as "black pollution", which are toxic and harmful garbage if not handled well, but are a renewable resource if handled properly.

The recycling of waste tires is a circular economic project. It is not only required that the cost of converting "waste" into new resources should be low and no new pollution sources will be generated; but also that the new resources converted from waste should have high utilization rate and wide range of availability. Otherwise, it will cause a backlog and waste of new resources, and it will not be possible to form a virtuous circle of turning waste into wealth. How to prevent the waste tire recycling process from polluting the environment is a problem that the world's waste tire recycling industry must solve. However, many existing methods and devices for recycling waste tires cannot or cannot solve the problem of separating rubber and steel wire in waste tires, which limits the effective recycling of waste tires.

Contents of the invention

The technical problem to be solved by the present invention is to provide a waste tire recovery device that can smoothly separate the steel wire and rubber in the waste tire, has high recovery efficiency and stable and reliable operation.

The waste tire recovery device of the present invention comprises a frame, a feed plate is installed at the front of the frame, a discharge plate is installed at the rear of the frame, and at least two groups of cutting devices are installed at the middle of the frame; each group of cutting devices includes A pair of pressure roller shafts arranged up and down and a pair of milling cutter shafts arranged up and down; a pair of pressure roller shafts are arranged with multiple pairs of pressure rollers at intervals, and a pair of milling cutter shafts are arranged with multiple pairs of cylindrical milling cutters at intervals, and adjacent The positions of the milling cutter and the pressure roller in the axial direction are mutually staggered; the milling cutters in each group of cutting devices jointly cover the entire width of the waste tire; the shaft of the pressure roller and the milling cutter are driven to rotate by the power device.

A beating shaft is also arranged between the cutting device and the discharge plate, and beating plates arranged radially are arranged on the beating shaft; the beating shaft is also driven to rotate by a power device.

Among the pressure roller shafts and milling cutter shafts arranged in pairs, the upper pressure roller shaft and milling cutter shaft are installed on an adjustment seat that can move up and down, and a compression spring is installed between the adjustment seat and the frame. The action of the spring makes the adjustment seat move within a certain range, so that the distance between a pair of pressure rollers or a pair of milling cutters can be adjusted to adapt to waste tires of different thickness specifications.

A dust suction device is also arranged above the cutting device to reduce dust pollution during processing.

In the present invention, through the pressure rollers and milling cutters arranged at intervals, the waste tires entering the cutting range are subjected to the mixed action of milling, extrusion and kneading, and the rubber layers on the surface of the waste tires are milled and kneaded to separate the rubber and the waste tires. The steel wires are recycled and reused separately, and the processing efficiency is high and the separation effect is good; the rubber remaining on the steel wires can be further knocked off by beating the waste tires after cutting with the beating board, and the separation effect is further improved; the installation above the device The advanced dust collection device can not only effectively improve the working environment, but also reduce the secondary pollution when recycling waste tires.

Detailed ways

The technical scheme of the device of the present invention will be further specifically described below in conjunction with the accompanying drawings.

As shown in the figure, the waste tire recovery device includes a frame 1, a feed plate 2 is installed at the front of the frame, a discharge plate 3 is installed at the rear of the frame, and at least two groups of cutting devices are installed at the middle of the frame; A group of cutting devices includes a pair of pressure roller shafts 4 arranged up and down and a pair of milling cutter shafts 5 arranged up and down; a pair of pressure roller shafts are arranged at intervals and many pairs of pressure rollers 6 are arranged at intervals, and a pair of milling cutter shafts are arranged at intervals of Multiple pairs of cylindrical milling cutters 7, and the positions of adjacent milling cutters 7 and pressure rollers 6 are staggered from each other in the axial direction; the milling cutters 7 in each group of cutting devices jointly cover the entire width of waste tires; The cutter shaft is driven to rotate by the power unit. A beating shaft 8 is also arranged between the cutting device and the discharge plate, and beating plates 9 arranged radially are arranged on the beating shaft; the beating shaft is also driven to rotate by the power unit. Among the pressure roller shafts and milling cutter shafts arranged in pairs, the upper or lower pressure roller shafts and milling cutter shafts are installed on an adjustment seat 10 that can be adjusted up and down, and a compression spring 11 is installed between the adjustment seat and the frame. Through the action of the compression spring 11, the adjustment seat can be moved within a certain range, so that the distance between a pair of pressure rollers or a pair of milling cutters can be adjusted to suit waste tires of different thickness specifications. There is also a dust suction device above the cutting device to reduce dust pollution during processing.

During the operation of the device of the present invention, the waste tires stretched into sheets enter the cutting device from the feed plate, and the pressure roller plays the role of pressing and conveying the waste tires forward. After being compressed by the pressure rollers, the rubber of the waste tires It is higher than the steel wire in the waste tire and protrudes, so that the milling cutter can more conveniently undertake the function of milling the rubber on the waste tire. There are three rollers or three milling cutters on each shaft, which can also be increased or decreased as required. The rotating shaft of the pressing roller of upper strata and milling cutter is installed on the regulating seat 10. The adjustment seat 10 is limited and buffered for its up and down movement by the stage clip 11, and the up and down movement range of the stage clip 11 can reach more than 10 mm, so as to facilitate the different processing of tire thickness.

After the tire is cut by the milling cutter, it enters the beating range of the beating plate 9, and the beating shaft 8 is driven by an electric motor. Falling on the steel wire, the rubber remaining on the steel wire is separated from the steel wire, so that the waste tires can be sorted and recycled with high quality.
