Spiral extrusion type excrement solid-liquid separation device capable of controlling solid humidity

Abstract

The invention discloses a spiral extrusion type excrement solid-liquid separation device capable of controlling the solid humidity, and relates to an excrement solid-liquid separation device. The device aims at solving the problems that an existing excrement solid-liquid separation device is high in maintenance cost and long in separation time, separated-out solid is high in moisture content, accordingly, the microorganism reaction environment cannot be effectively controlled, and a screen net type solid-liquid separation device is likely to be blocked. The device is composed of a motor, a separator shell, a screen drum, a packing auger and a discharge outlet compression cover. A packing auger shaft of the packing auger is provided with multiple spiral blades. The thread distance of each spiral blade is gradually reduced from the side of the closed end of the separator shell to the side of a conical opening of the separator shell. The screen drum is composed of multiple wedge-shaped strip plates distributed at equal intervals. The inner wall of the screen drum is provided with multiple blocking teeth. The device is stable in operation, solves the problem that blockage is likely to be caused, can control the humidity of solid waste, can meet the requirements of fungi for living environment to enable fungi to be in the optimal fungus living and growth conditions, and is applicable to excrement solid-liquid separation.

Description

technical field

[0001] The invention relates to a stool solid-liquid separation device. Background technique

[0002] Human feces contain a large amount of organic substances, which are biological resources that can be recycled through biodegradation. If they are not utilized and discharged directly, it will cause a great waste of resources; in addition, feces contain a large number of pathogenic bacteria, heavy metals and other Hazardous substances must therefore be disposed of effectively. The ecological toilet is an environmentally friendly toilet that uses microorganisms to convert human excrement into organic fertilizers or soil improvers, which solves the problems of fecal pollution and organic matter enrichment. However, the existing ecological toilets generally use feces-urine integrated reactors. Because the moisture content of the reactor feed cannot be effectively controlled, the humidity of the microbial growth environment is difficult to control, the growth con...
