Garbage crushing device capable of feeding materials under negative pressure

Abstract

The invention discloses a garbage crushing device capable of feeding materials under negative pressure. The garbage crushing device capable of feeding materials under negative pressure comprises a support frame, a crushing unit, a lifting opening and closing device and a conveying belt device, wherein the support frame is a cuboid; a rectangular accommodating cavity is formed in the cuboid; a pairof feeding guide blocks is formed on the upper side wall of the support frame; a cylindrical crushing and discharging barrel of a device with the unsealed bottom is formed on the lower side wall of the support frame; the lower ends of the feeding guide blocks are fixed on the crushing and discharging barrel; a downward feeding guide hole which is inwards inclined is formed in each feeding guide block; the feeding guide holes communicate with a cavity of the crushing and discharging barrel; an annular crushing and isolating ring and a closed isolating ring are formed on the inner side wall ofthe crushing and discharging barrel from top to bottom; upper end surfaces and lower end surfaces of the crushing and isolating ring and the closed isolating ring are conical tables which are projected downwards; the crushing unit is arranged on the upper side wall of the crushing and discharging barrel; and an opening and closing sealing block is arranged in the crushing and discharging barrel ina lifting manner. The garbage crushing device can continuously crush garbage, a discharging mode is simple, and the working efficiency is high.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a garbage crushing device for negative pressure feeding. Background technique [0002] Garbage refers to unnecessary or useless solid and fluid substances. In densely populated cities, garbage disposal is a headache. The common practice is to collect them and send them to landfills for landfill treatment, or use incinerators Incineration, but both will cause environmental protection problems, and ending excessive consumption can further reduce the saturation of landfills. Garbage disposal in landfills will not only pollute groundwater and emit odors, but also many cities that can be landfilled The area has become smaller and smaller, and incineration will inevitably produce toxic gases, which are harmful to organisms. Most cities are researching ways to reduce garbage production and encourage resource recycling. On October 14, 1992, Shenzhen, Guangdong Realize a...

Problems solved by technology

[0003] The problem of garbage has always troubled people. With the development of society, the amount of garbage is gradually increasing. At present, the more common methods of garbage disposal are landfill and incineration. In the process of garbage landfill and incineration, it is often necessary Smash to improve the degradation rate and incineration efficiency of garbage. The structure of the existing garbage crushing device is relatively simple. After the crushing is completed, it is difficult to take out the garbage, and it is impossible to realize automatic discharge, which affects work efficiency and increases the burden on workers.
