Coarse crushing device for large garbage

Abstract

The invention provides a coarse crushing device for large garbage. The coarse crushing device comprises a crusher and a magnetic separator in butt joint with the crusher, and is used for sequentiallycompleting crushing and sorting of the large garbage, wherein the crusher is provided with a plurality of cutter shafts; a plurality of blades are arranged on the cutter shafts; and the blades have atleast two size specifications with different diameters or different shapes or different diameters and shapes. Due to the fact that the cutter shafts of the crusher are provided with the blades with different size specifications or shapes, the situation that the large garbage cannot eat materials when rolling on the cutter shafts can be avoided, and the crushing efficiency is improved; and sortingis carried out after crushing, reasonable recycling is carried out, and the resource utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a rough crushing equipment for oversized garbage. Background technique [0002] With the rapid development of my country's economy, the rapid advancement of urbanization, and the improvement of people's living standards, the large-scale garbage generated in the process of housing decoration, relocation, and residents' waste furniture renewal is also increasing day by day. Bulky waste refers to waste that weighs more than 5kg or has a volume greater than 0.2m 3 Or waste with a length of more than 1m in one direction and strong integrity that needs to be disassembled for reuse or treatment. And this kind of garbage has a strong integrity and may be reused or processed after being broken. Due to its large size, ordinary garbage truck transfer vehicles are difficult to operate, and subsequent processing after operation is also very troublesome. As the earth's r...

AI Technical Summary

Problems solved by technology

[0004] 1. The length of the hook of the existing crusher is short: when crushing bulky waste, sofas, iron barrels, tree stumps and other large-sized wastes will spin on it, and cannot be crushed directly. External equipment is needed to squeeze the bulky waste , let them deform, and the knife hook can rub and squeeze the big garbage;

[0005] 2. The existing crusher has a large number of knife hooks, and there will be 2 or more knife hooks appearing at the same time on the tangential plane of the diameter of the same shaft. Ordinary machines with two or more shafts will produce 4 or 4 When the above fulcrums appear, oversized garbage is often lifted and slipped;

[0006] 3. The operation mode is single, and an external pusher is needed to assist in crushing: the existing shearing type crushing knife hook is short and has many knife hooks, breaking sofas, iron barrels, garden wood and other large pieces of garbage is easy to slip and jumps on the knife hooks , it is necessary for the pusher to squeeze sofas, iron barrels, and garden wood to deform them, so that the knife hook can tear and cut;

[0007] 4. Low work efficiency: the knife box is small in size, with a screen at the bottom, the output is limited, pure shearing is laborious, and the material needs multiple shears to pass through the holes of the screen, the screen will sometimes be blocked, the output is small, and the cutter Rotating and colliding with the material, repeated friction between the tool and the material slipping, repeated shearing of the material, and a short service life;

[0008] 5. Poor motor drive stability, low impact resistance and high energy consumption

The motor is prone to failure when encountering problems such as material jamming, resulting in long-term shutdown;

[0009] 6. Dust pollution is caused, and there is no dust removal process in the current situation, which is harmful to the health of on-site personnel;

[0010] 7. The labor cost is high, the reason: the automation of the equipment is low, every link is manually operated, and there is no integrated control;

[0011] 8. The degree of resource utilization is low, the size of the crushed material is large, and the next step of separation cannot be carried out, or the separation is not obvious
