Household garbage selective crushing device

Abstract

The invention relates to the technical field of environmental protection equipment, in particular to a household garbage selective crushing device which comprises a base, a drum arranged on the base and a driving mechanism. The drum comprises a drum body and a spiral guide plate arranged on the inner wall of the drum body, a feeding port and a discharging port are formed in the two ends of the drum body, the feeding port and the discharging port are each provided with a guide plate, and the feeding port is further provided with a zymophyte liquid adding device; the device further comprises a crushing body combination used for crushing household garbage, the crushing body combination comprises a plurality of cutting bodies and a plurality of crushing bodies in different shapes, the cutting bodies and the crushing bodies are welded to the inner wall of the drum body and arranged at intervals, and each crushing body comprises a combination of at least two or more of a sphere, a conical body, a polyhedron and a special-shaped body; and a plurality of sawteeth are arranged on the surface of each cutting body. The device can selectively and quickly crush and pulpify kitchen garbage and paper garbage which are difficult to separate in mixed household garbage, and eliminate peculiar smell of organic matters such as the kitchen garbage, so that the treatment process is greatly simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a selective crushing device for domestic garbage. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, more and more domestic waste is produced. These domestic waste mainly include kitchen waste, recyclable domestic waste and toxic and harmful domestic waste. At present, the most commonly used method of domestic waste disposal is to incinerate and bury the collected domestic waste. However, burning domestic waste will produce harmful gases and cause air pollution, and burying domestic waste will cause groundwater pollution. At the same time, domestic waste may be Recycled materials are wasted, so how to properly dispose of these domestic wastes and sort out recyclable domestic wastes has become an urgent problem to be solved.

At present, the most commonly used method of domestic waste disposal is to incinerate and bury the collected domestic waste. However, burning domestic waste will produce harmful gases and cause air pollution, and burying domestic waste will cause groundwater pollution. At the same time, domestic waste may be Recycled materials are wasted in vain, so how to properly dispose of these domestic wastes and sort out recyclable domestic wastes has become an urgent problem to be solved

[0003]In the prior art, some people in the industry first pass through multiple screening processes such as manual sorting, winnowing, magnetic separation, solid-liquid separation, and sedimentation treatment. For further crushing and beating, the above method needs to go through multiple complex processes, which is not only costly, but also unable to effectively separate kitchen waste from recyclable paper waste; in addition, since kitchen waste contains a large amount of For organic matter, the process of removing impurities through the above multiple screening processes is likely to cause odor pollution and odor pollution, and the odor is very strong, and then the remaining kitchen waste after screening is passed through the high-speed beating of the beater or pulper Forming slurry, the high-speed beating process consumes a lot of energy, and the equipment requires that some hard impurities in the material must be removed, otherwise it will cause damage to the equipment
