Bag tearing device and bag tearing method

Abstract

The invention discloses a bag tearing device and a bag tearing method. The bag tearing device comprises a machine shell, a spiral conveying device and a bag tearing tool. A feed inlet and a discharge outlet are formed in the machine shell. The spiral conveying device and the bag tearing tool are both arranged in the machine shell. The bag tearing tool comprises a tool driving device, a reduction gear, an installation disc and a plurality of tool bodies. The installation disc is in an annular shape. The multiple tool bodies are sequentially arranged and fixed to the inner wall of the installation disc in the circumferential direction. The tool driving device is connected with the reduction gear. The installation disc and the reduction gear are mutually fixed. The installation disc is located at the front end of the spiral conveying device. The installation disc and the spiral conveying device are coaxially arranged, and the rotating direction of the installation disc and the rotating direction of the spiral conveying device are opposite. According to the bag tearing device, garbage bags can be torn and broken under the condition that conveying is not influenced; the treatment process is smooth and continuous, the equipment failure rate is low, the structure is simple and compact, and the cost is low.

Description

technical field [0001] The invention relates to a garbage treatment device and a treatment method, in particular to a bag breaking device and a coarse crushing method for bagged garbage such as bagged household garbage, kitchen garbage and kitchen waste. Background technique [0002] In the field of solid waste treatment, especially in the pretreatment of domestic waste, kitchen waste and kitchen waste, the shape and composition of waste are complex, and there are a large number of bagged waste, most of which are packaged in plastic. At present, many new processes have been adopted in my country to deal with domestic waste, kitchen waste and kitchen waste. Especially for organic waste, biochemical methods such as anaerobic fermentation process and aerobic fermentation process are adopted. Fluidization is used in primary waste incineration. Bed incineration process, etc., the above-mentioned process methods all need pretreatment of raw waste in order to improve the quality and...

AI Technical Summary

Problems solved by technology

[0003] Among them, the plastic bags in the garbage are thin and light, and are difficult to degrade. Before the plastic bags are broken, it is difficult for microbial strains to penetrate the plastic bags and contact organic materials, and cannot achieve biochemical reactions; and the strips formed after the plastic bags are broken The fiber is easy to cause blockage and entanglement to the crushing equipment, and the passability is poor, resulting in a high failure rate of the equipment
