Description

Efficient and environmentally friendly scrap metal shredder

technical field

The utility model belongs to the technical field of scrap metal recycling, and in particular relates to a high-efficiency and environment-friendly scrap metal shredder.

Background technique

Scrap metal crushing is an important step to turn waste automobile bodies, old household appliances, bicycles, empty cans and other inferior waste into superior steel-making raw materials. This process needs to be completed by scrap iron crushers. Continuously pulverize, remove the coating film, increase the volume specific gravity, prevent explosion when the electric furnace is put into the furnace, and increase the dissolution rate under certain conditions, so as to meet the requirements of "concentrated materials into the furnace" of steel mills.

Its working principle is to use the basic principle of hitting with a hammer. Driven by a high-speed and high-torque motor, the hammer heads on the rotating shaft of the main engine hit the scrap iron in the cavity in turn, and pass through the space formed between the liner and the hammer head. , Tear the scrap iron sheet into pieces that meet the specifications. Broken materials pass through the air rotary sorting system to separate metal and non-metal. In addition, the whole system is equipped with a dust removal device to minimize the dust pollution hazards generated during the production process.

However, the existing scrap iron crusher only beats the scrap iron material through the hammer head. This crushing method increases the force on the hammer head due to the lack of shredding, which not only increases the wear and tear of the hammer head, but also has low efficiency. , In addition, the existing crushers are all single-roll crushers, which require a long time for crushing to complete the crushing, and the crushing efficiency is low.

Utility model content

The technical problem to be solved by the utility model is the technical problem of low efficiency of the existing scrap metal crusher, and a kind of double-roller metal scrap crusher is provided.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

The high-efficiency and environment-friendly scrap metal crusher of the utility model includes the main machine of the crusher. Door oil cylinder, a crushing roller is arranged vertically and horizontally in the lower box, and a crushing hammer and a crushing knife are arranged at intervals on the crushing roller. The side of the body is hinged, the cylinder tail of the overturning oil cylinder is hinged with the mounting seat of the lower box, the upper cover is fixedly connected to the top of the upper box, the upper discharge door is vertically rotated on the upper part of the upper box, and the upper discharge door One end is hinged with the piston rod of the upper discharge door cylinder, the other end is free to place, the cylinder tail of the upper discharge door cylinder is hinged with the side of the upper box, the grille is set in the lower box and placed under the crushing roller , the discharge opening is placed under the grille and at the bottom of the lower box on the rear side.

The crushing roller includes a main shaft and a baffle, and the baffle has several pieces, and several pieces of baffles are set on the main shaft at intervals along the length direction of the main shaft, and the baffle sleeve I and the baffle sleeve II are placed between two adjacent baffles. on the main shaft between them, and the partition sleeve I and partition sleeve II are arranged at intervals, the hammer head shaft is installed on the outer periphery of several partition boards along the length direction of the main shaft, and the two adjacent hammer head shafts are arranged at 90° to each other. There are multiple pieces of crushing hammer head, which are rotated and set on the hammer head shaft between two adjacent partitions; there is a crushing knife installation groove around the partition, and the two adjacent installation grooves are arranged at 90° to each other, and the crushing knife is fixed on the In the installation groove; the crushing hammer head and the crushing knife are set at intervals.

Adopting the above-mentioned technical scheme of the utility model, the crushing knives and the crushing rollers are arranged at intervals on the crushing rollers, the crushing knives are evenly distributed on the turntable, and each crushing knife can be freely disassembled on the turntable, and the crushing knives can be placed on two opposite sides of the turntable. The clapboards are alternately installed and used, and the large scrap iron is shredded by the shredding knife; then hit and crushed by the breaking hammer, and is crushed into small material particles by the hammer under the interaction of the breaking hammer and the grid, and the waste is solved. The problem of low crushing efficiency of metal crushers has strong promotion and application value.
