High-efficiency combined type domestic garbage crusher

Abstract

The invention relates to a high-efficiency combined type domestic garbage crusher, which belongs to the technical field of domestic garbage crushing and comprises a feed hole, a crushing system, a discharge system and a transmission system, wherein the crushing system comprises dual knife rolls, a moving knife group, a static knife group and a knife adjusting device; the discharge system comprises a left screen, a right screen and two discharge holes; and the transmission system comprises a motor and a synchronous gear group, and the synchronous gear group ensures the synchronous running of the dual knife rolls. The left knife roll and the right knife roll are arranged side by side in parallel, a certain gap is reserved between the two knife rolls, and the two knife rolls are connected by the synchronous gear group and run in opposite directions; and the knife rolls are provided with rotating moving knives, the bottoms of the knife rolls are provided with bottom blocks, the bottom blocks are provided with bottom static knives, and simultaneously a frame is provided with a side static knife. Firstly, domestic garbage is crushed in the gap between the two knife rolls, is crushed at the position of the bottom knives after being compressed, then passes through the left screen and the right screen and is respectively discharged from the left discharge hole and the right discharge hole; and the side static knife can crush the garbage with bigger size again. The invention has the advantages of large treatment capacity, high crushing efficiency and low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of household garbage crushing, and in particular provides a high-efficiency composite household garbage crusher, which is suitable for crushing light organic matter on garbage sieves. Background technique [0002] Municipal solid waste has become a global urban environmental problem, especially in our country. The current direct landfill method of primary waste can no longer meet the requirements of the era of circular economy and low-carbon economy. Clean energy treatment and utilization of waste and comprehensive treatment of waste have become the development direction of "reduction, resource utilization, and harmless" treatment of waste. . In the clean energy and comprehensive treatment of waste, the crushing equipment that sieves organic light waste after sorting becomes the key. Most of the existing equipment belongs to the special crushing equipment for waste plastics, and the production capacity can...

Problems solved by technology

[0005] Although the above methods have improved the productivity of the crusher to a certain extent, the increase is not ideal, and there are still two main problems:

[0006] 1. Only small-volume plastics can be crushed, and large-volume plastics cannot be crushed directly. Therefore, before crushing large-volume waste plastic products or packaged plastic films, it is usually necessary to pass through a plastic shredder to reduce the volume. Larger plastics are disintegrated and shredded into strips, and then the strips of plastic are broken into small pieces by a crusher;

[0007] 2. The effect of crushing hard plastic is good, but the crushing efficiency of film plastic is low, and there is a phenomenon of difficulty in feeding. The film is repeatedly circulated in the silo, and it can only leak out of the screen when it has been crushed many times to meet the size requirements, resulting in material discharge. The speed is slow, so its processing efficiency and processing capacity are difficult to achieve the expected goals

[0008] According to the needs of the development of garbage treatment technology and the problem of insufficient processing capacity in the existing waste plastic crushing equipment, a crusher that can meet the large-scale crushing and processing of organic light substances on the garbage screen is proposed to fill the large-scale and efficient crushing of domestic waste device blank
