Household garbage and biomass crushing device

Abstract

A household garbage and biomass crushing device mainly comprises a bar saw type sawing mechanism, a cutting type crushing mechanism and a filtrate and slag separation mechanism, all of which are sequentially installed on a support. Materials crushed by the bar saw type sawing mechanism for the first round enter the cutting type crushing mechanism to continue to be subjected to cutting type crushing for the second round, filtrate and slag generated after the bar saw type sawing mechanism and the cutting type crushing mechanism crush household garbage or various kinds of biomass or shells are collected by the filtrate and slag separation mechanism, and the filtrate and slag separation mechanism discharges the separated filtrate to a filtrate collecting mechanism and discharges the separated slag to a crushed material collecting mechanism. The household garbage and biomass crushing device is relatively simple in structure, capable of achieving material selecting and manufacturing easily, low in manufacturing cost, high in crushing efficiency, low in energy consumption and capable of completely eradicating secondary pollution, and the crushing device is small in occupied area, convenient to install and place, high in adaptability, capable of being used in villages, towns, schools, enterprises and islands conveniently and easy to popularize and apply.

Description

technical field [0001] The invention relates to environmental protection technical equipment, in particular to a domestic garbage and biomass crushing device. Background technique [0002] With the strengthening of human environmental protection awareness, the harmless, resourceful and reduction of domestic waste has become the future development direction. Among them, the waste crushing device, as the main equipment for domestic waste treatment, is widely used in waste crushing and landfill, waste incineration power generation, Waste cement kiln co-processing and other processes. At present, the garbage sorting system is fully implemented at the national level, but the construction of most municipal solid waste sorting and processing systems is not perfect, coupled with the weak awareness of garbage sorting among Chinese residents, resulting in complex components of domestic waste, mainly including waste plastics, waste paper, fabrics, animal and plant remains, For waste wo...

AI Technical Summary

Problems solved by technology

At present, the garbage sorting system is fully implemented at the national level, but the construction of most municipal solid waste sorting and processing systems is not perfect, coupled with the weak awareness of garbage sorting among Chinese residents, resulting in complex components of domestic waste, mainly including waste plastics, waste paper, fabrics, animal and plant remains, For waste wood, meal waste, waste rubber, a small amount of construction waste, etc., the toothed roller garbage shredding device imported from abroad cannot adapt to my country's national conditions, and the garbage shredders on the market generally adopt forced shearing and tearing of materials, which has a large crushing resistance, Low efficiency, high energy consumption and inconvenient maintenance

[0003] In response to the above-mentioned problems, domestic scientific research and technical personnel have carried out relevant research. For example, CN201710833001.8 announced a push-shear type garbage crusher, which mainly increases the hydraulic pusher device to improve the efficiency of garbage feeding, but there are the following problems: First, it adopts low-speed and high-torque toothed roller crusher, which has a low processing capacity per unit time; second, adopts toothed roller structure, which mainly achieves crushing through extrusion and shearing, in which extrusion causes material deformation and heat, which ultimately leads to efficiency. Low; third, the structure is complex, and the hydraulic pusher is used to push the material, which increases the complexity of the system; fourth, due to the complex structure, low speed, and high torque, the equipment is heavy and the cost is high

CN201710219221.1 discloses a garbage crusher, which mainly includes a pushing chamber, a pushing head, a crushing device, a crushing knife set and a throwing knife set, and its feeding port is located at the top. If hard long strip materials are encountered, only the pushing head The action efficiency is extremely low, and effective crushing cannot be achieved. In addition, the material processed by the crushing knife set and the flinging knife set may still become strips and cannot be completely crushed, which affects the subsequent application of the crushed material

CN202010031250.7 discloses a shredder for domestic waste, which mainly includes two squeeze rollers, a crushing device and a crushing device, etc., but there are still the following problems: First, the use function is single, and the setting of the squeeze roller limits the amount of raw materials. Feed size, for raw materials such as waste wood, straw and other biomass other than domestic waste, it cannot be effectively squeezed and crushed; second, the crushed material after the crushing device is only cut longitudinally, and it is easy to form long strips of materials, and at the same time It may cause long strips of garbage to be entangled on the crushing knife; third, the crushing device only relies on ball friction to crush, and the crushing effect cannot be guaranteed due to the complex composition of domestic waste

[0015] Other biomass raw material crushing methods include airflow crushing, vibrating crushing and stirring grinding and crushing, etc. These kinds of crushing equipment are mainly used for ultrafine crushing of materials. High energy consumption and high manufacturing cost, generally used for crushing materials with high product performance requirements

[0016] To sum up, although domestic waste and biomass pulverization and treatment technologies in my country have developed rapidly, due to the variety of types, shapes, thickness and length of domestic waste and biomass raw materials, especially the domestic waste, forest residues and other biomass The moisture content of the raw material is high and the crushing requirements are high, so the existing single domestic waste crushing equipment or biomass crushing equipment cannot meet the requirements, and there is currently no equipment that can be compatible with domestic waste and biomass crushing treatment at the same time, resulting in the occurrence of domestic waste and the poor effect of biomass crushing, high operating costs and limited application range of crushed materials, etc.
