Description

A four-shaft shredder for solid waste

technical field

The utility model relates to the field of solid waste treatment equipment, in particular to a four-shaft shredder for solid waste.

Background technique

In people's lives, there are many types of solid waste. From the perspective of sources, they can be divided into mining waste, industrial waste, agricultural waste, radioactive waste, and urban waste, while urban waste is divided into kitchen waste, domestic waste, and electronic waste. and medical waste. For the recycling of urban waste, the current crushing equipment mainly includes the following categories: (1) Single-shaft shredder. In this structure of the shredder, in order to better grasp the material, the knife teeth have a long overhang. Therefore, it is difficult to reduce the thickness of the blade, and it is difficult to reduce the shredded particle size of the material, so it is difficult for the single-shaft shredder to shred the material with a small particle size; (2) the double-shaft shredder, in the current production and life applications The outstanding problem of the shredder with this structure is that it is difficult to grab large materials, so it is often necessary to use auxiliary mechanisms to press materials into the biaxial shredder, which affects the efficiency of feeding on the one hand, and also on the other hand. Increases the cost of equipment, which is not conducive to the control of garbage recycling costs; (3) four-axis shredders, currently used four-axis shredders generally drive four hob shafts through four geared motors, that is, each hob The shaft needs to be equipped with a deceleration motor correspondingly. The shredder with this structure occupies a large area and the equipment cost is high, so it is difficult to adapt to a wide range of popularization and application.

The lower right hob shaft drives the upper right hob shaft to rotate through the right chain and the corresponding sprocket.

In addition to the above-mentioned structure, the four-axis shredder used for solid waste can also be connected to the controller externally, so as to realize the adaptive shredding of the four-axis shredder, that is, when shredding different materials, the controller can Control motor rotation. That is to say, when the resistance is too large, the hob will automatically reverse, return the material, and repeat the shredding for many times. If it still cannot be shredded after many attempts, an alarm will be issued.

Compared with the prior art, the utility model has the following beneficial effects:

The four-shaft shredder for solid waste has a simple structure, a small footprint, and low equipment cost, and is especially suitable for indoors, ships, and even households with small processing volumes. At the same time, compared with the existing equipment, this four-axis shredder has greatly improved the feeding capacity, broadened the size range of solid waste that can be processed, and larger materials (such as plastic pots, cartons, etc.) no longer need to be manually pressed. The labor intensity is reduced, and the processing efficiency is also greatly improved.
