Heat-insulating and anti-freezing digestion tank and heat-insulating and deodorant toilet

Abstract

The invention discloses a heat-insulating and anti-freezing digestion tank. The heat-insulating and anti-freezing digestion tank comprises an outer housing, an inner tank body and a heat insulating layer between the outer housing and the inner tank body, wherein the inner tank body is in a big-end-up cuboid barrel structure and made of plastic materials; the outer housing is in a big-end-up roundbarrel structure and made of plastics, glass fiber reinforced plastics or metal materials; the heat insulating layer is made of polystyrene foam. The invention also discloses a heat-insulating and deodorant toilet. The heat-insulating and deodorant toilet comprises a cover plate arranged above the heat-insulating and anti-freezing digestion tank, a toilet stool arranged on the cover plate, a harmless dung liquid extractor and an exhaust pipe. Divided into the inner tank in the big-end-up cuboid barrel structure and the outer housing in the big-end-up round barrel structure, the heat-insulatingand anti-freezing digestion tank can avoid the risk of frozen cracking in cold winter. The heat-insulating and deodorant toilet achieves heat-insulating, anti-freezing and deodorant effects, and is low in cost, high in practicality and particularly applicable to northern cold and arid regions.

Description

technical field [0001] The invention relates to the technical field of sanitation facilities, in particular to a thermal insulation and antifreeze type septic tank and a thermal insulation and deodorizing toilet. Background technique [0002] The septic tank is a device for treating feces and filtering sediment, which belongs to the primary filter life treatment structure. Existing septic tanks have the following types: the first type, cast-in-place reinforced concrete septic tanks, brick septic tanks. This kind of septic tank has the following problems, such as being affected by the climate, it is inconvenient to construct in winter, and it is difficult to construct in low-temperature climates; the bigger problem is that this kind of septic tank begins to leak seriously after several years of use, which will pollute underground drinking water sources and urban underground water supply pipes. The second type is a plastic septic tank. The existing plastic septic tanks also...

AI Technical Summary

Problems solved by technology

The existing plastic septic tanks also have limitations when used in cold northern regions. Due to the large and small structure of the existing septic tanks, when it freezes in winter, the septic tanks often suffer from frost heaving Cracks occur, resulting in leakage pollution, and the water seal cannot be used to solve the airtight problem after freezing in winter, and the deodorization, heat preservation, and fermentation effects are poor

[0003] This shows that above-mentioned existing septic tank still has inconvenience and defective, and demands urgently further improving
