Crude separation mechanism for liquid dung

Abstract

The invention discloses a coarse separation mechanism for excrement and water, which belongs to the field of urban sanitation equipment. At present, in the process of separating and collecting urban excrement and water, a sieve structure is used for impurity removal. This method will simultaneously remove inorganic impurities such as large pieces of organic matter and mixed plastics. Filtration, this link will lead to the loss of a large amount of organic matter, resulting in waste of organic matter, and the removal of large debris will lead to low separation efficiency. It should also be pointed out that in the existing separation equipment, vacuum pumps and closed storage bins are often used for material separation. Inorganic impurities mixed with organic matter will quickly fill up the storage bin and make it difficult to clean, affecting the effective use of the equipment. . On the one hand, the present invention improves the separation efficiency by crushing bulk organic matter and inorganic matter such as plastics; on the other hand, it can effectively reduce the loss of organic matter components caused by filtering out inorganic matter. At the same time, this design realizes self-cleaning by setting a cleaning comb structure Function, reduce equipment maintenance costs.

Description

technical field [0001] The invention relates to a coarse separation mechanism for feces and water, which belongs to the field of urban environmental sanitation equipment. Background technique [0002] In the past ten years, with the development of my country's economy, the pace of urbanization has been accelerated, urban residents have grown rapidly, and more and more people are using flush toilets. If the population of rural market towns is included, at least 500 million of the total population of nearly 1.4 billion are urban residents. According to reports, the annual feces output per person is 3.95 kg of pure nitrogen and 0.75 kg of pure phosphorus. It can be seen that 1.97 million tons of pure nitrogen fertilizer and 370,000 tons of pure phosphorus are discharged into rivers from human feces every year. The discharge of nitrogen and phosphorus directly threatens the water quality of rivers and lakes, seriously affects the quality of local aquatic products and agricultur...

Problems solved by technology

[0004] In view of the current separation and collection process of urban manure and water, the sieve structure is used to remove impurities. This method will simultaneously filter out inorganic impurities such as large pieces of organic matter and mixed plastics. This link will lead to a large amount of organic matter loss, resulting in waste of organic matter. Removal of lumps leads to inefficient separation
