Description

Shredder for decommissioned car bodies

technical field

The invention relates to a metal crushing device, in particular to a crushing device for a decommissioned automobile body. The utility model belongs to the technical field of scrap steel processing equipment.

Background technique

In recent years, the rapid growth of the domestic automobile market has attracted widespread attention, and the resulting problems in the field of automobile recycling have become increasingly prominent. Statistics show that as the world's largest automobile production and sales country, my country's automobile production and sales exceeded 20 million for the first time in 2013, ranking first in the world for the fifth consecutive year. As of the end of 2013, the number of automobiles in my country has reached 137 million. According to the annual decommissioning or scrapping amount of 5%, the annual decommissioning of automobiles is 6.85 million. It is estimated that by 2020, there will be more than 10 million decommissioned vehicles in my country. How to deal with and utilize these increasingly large decommissioned vehicles is not only the need for environmental protection, but also the need for economic strategic development to achieve comprehensive utilization of resources and sustainable economic development. Therefore, it is urgent to efficiently recycle and reuse the decommissioned car body. And before recycling the bodies of decommissioned cars, they need to be shredded.

The dismantled body shells of decommissioned cars must be processed before the fine materials can be put into the furnace. At present, there are two main treatment methods for decommissioned automobile bodies in my country, one is packaging and the other is crushing. Among them, the packaging process includes direct packaging and cutting and packaging, and direct packaging requires large-scale equipment; although the equipment used for cutting and packaging is small, it needs to go through one more cutting process; There are many impurities and are easy to be doped, so it is not energy-saving during steelmaking, and there are more carbon emissions, which is not conducive to environmental protection. Crushing treatment includes direct crushing and crushing after pretreatment: the high-power crushing line can directly crush the retired car body, but due to the large investment, high-voltage power supply, and large floor area, it is difficult to market. However, due to the small power and small import of small scrap steel crushers, pretreatment must be carried out before crushing, so there are also problems of increasing procedures and equipment.

The Chinese patent (authorized announcement number: 101530822B) authorized in 2011 proposes a steel scrap crusher, which includes a feeder with hydraulic double drums and a crusher host. Although the power of this crusher is small, and its production efficiency is slightly higher than that of ordinary crushers, but before crushing the retired car body, it must be pretreated, that is, it must be cut, compressed, and shaped before it can be smoothly fed into the feed material. At the mouth, there is a problem of increasing procedures and equipment, and the crushing efficiency is low and the cost is high.

The Chinese patent (authorized announcement number: 102166578B) authorized in 2013 proposed a pre-treatment process and equipment for waste car shells. The equipment provides a complete set of pre-treatment processes including shredding, crushing, dust removal, and sorting. With two-stage crushing function, the crushing effect is good and there is no pollution. However, the equipment includes multiple machines and conveyor belts, which consumes a lot of energy and occupies a large area; the equipment uses a double-shaft shredder and a double-motor-driven vertical crusher in the crushing part. The crushing effect is better, but the vertical crusher used in this equipment has a lower production capacity than the horizontal crusher, and is not suitable for high-efficiency crushing in large quantities.

The Chinese patent authorized in 2013 (authorized announcement number: 202823482U) proposes a special crusher for scrapped cars. The crusher integrates a shredder, a breaking hammer and a rolling hammer into one main shaft roller to directly crush scrapped car shells. Body, high efficiency, low energy consumption. However, although integrating the shredder, breaking hammer and rolling hammer into one main shaft roller at the same time will make the structure of the whole crusher more compact, compared with a separate double-shaft shredder and a Broken and broken, the broken effect is still poor.

Therefore, in view of the problems existing in the existing decommissioned automobile body crushers, it is extremely important to seek a decommissioned automobile body crushing device that can directly crush decommissioned automobile bodies, has high work efficiency, low energy consumption, small footprint, and a relatively simple structure. .

The above-mentioned decommissioned automobile body crushing device provided by the present invention is used in dismantling and processing the decommissioned automobile body.

In the process of dismantling and processing the body of the decommissioned automobile, the body enters the chassis box through the hopper, and the volume of the body material can be reduced under the extrusion of the screw feeding extrusion device; the extruded body is pre-pressed by the screw Rolling and rotating feeding, as well as the joint action of its own gravity, continue to fall, and the deformation and shredding of the biaxial shredding device realizes the preliminary crushing of the body material; the shredded body material enters the hammer crushing device, and after hammer crushing The hammering of the device is further crushed. After the crushed body material reaches the specified size, it is filtered through the metal screen and reaches the discharge port.

The size of the shredded body can be 100-500mm in length and 50-100mm in width.

The body size after crushing can be ≤Φ80mm.

Compared with the prior art, the present invention has the following main advantages:

1. A screw feeding extrusion device is installed on the feed port of this device. The retired automobile body is fully extruded after entering the hopper, which is equivalent to the pretreatment process before crushing. After the body is compacted, the crushing rate can be significantly improved. Efficiency; and under the effect that the body material is continuously squeezed in the hopper 1, the volume of the body material decreases, and the extruded body can realize high-efficiency progress under the joint action of the pre-rolling and rotating feeding of the screw rod and its own gravity. material purpose. This not only shortens the process, saves costs, but also improves work efficiency.

2. Two-stage crushing is adopted in this device, that is, the pre-extruded decommissioned car body is shredded into smaller volumes by a biaxial shredding device, and then crushed by a horizontal crushing device. The crushing effect is good, and the efficiency is improved and the energy consumption is reduced.

3. The feeding device and the two-stage crushing device in this device are placed from top to bottom, which not only saves the floor space, but also utilizes the gravity of the body itself to complete the step-by-step crushing of the feeder, without the need for the body feeding conveyor belt, etc. device, reducing installation and energy consumption.

In a word, the decommissioned automobile body crushing device has the advantages of simple structure, high working efficiency, small footprint and strong practicability.
