Description

Feces harmless chemical toilet suitable for cold area

Technical Field

The utility model belongs to the field of harmless treatment of excrement, and particularly relates to an excrement harmless toilet suitable for cold regions.

Background

At present, along with the continuous promotion of toilet improvement work in rural areas, the popularization rate of the rural toilet is stably improved, and the popularization rate of the Chinese rural sanitary toilet exceeds 68 percent by the end of 2020. The toilet changing technology mainly takes 6 harmless sanitary toilets recommended by 'rural sanitary household toilet code' as a main part, wherein three-grid septic-tank type toilets, double-pit alternate type toilets, excrement and urine diversity type toilets and double-urn funnel type toilets have the same characteristics in structure: septic tanks and excrement storage tanks in different forms are arranged below the toilet room and are all made of plastic materials. The toilet has stronger adaptability and better treatment effect on the excrement in southern areas of China, but the toilet has unsatisfactory use effect in partial cold areas of China, and especially the excrement is easy to freeze and swell in the septic tank under the low-temperature condition in winter, so that the harmless process of the excrement in the septic tank stops in winter, and the septic tank is damaged and cannot be used.

Patent No. CN211472762U proposes an outdoor anti-freezing toilet for northeast, which uses deep-burying technology to bury the septic tank in the non-freezing layer under the frozen soil layer soil, so as to solve the problem that the toilet cannot be used due to frost heaving and cracking of the septic tank which often occurs because of freezing in winter in the northeast. Although the freezing of the septic tank of the toilet is relieved in a deep burying mode, the problems that the frozen soil layer of the northeast area, particularly the area north of Yichun in Heilongjiang, can reach more than 6m, the construction difficulty under the frozen soil layer is high, the septic tank is difficult to maintain and clearly draw out and the like are not considered.

Patent No. CN201610005528.7 proposes a septic tank of an anti-freezing toilet, which improves the compression resistance and corrosion resistance of plastics by a new process, and then uses the modified plastics to manufacture a septic tank heat preservation device, thereby playing a certain role in heat preservation. Although the heat preservation device made of the modified plastic has a certain heat preservation effect, the problem of expansion and cracking of the septic tank caused by frost expansion of excrement still exists when only the heat preservation device is not enough to maintain partial excrement water in the septic tank to be not frozen for a long time and not to be frost-expanded under the condition of continuous low-temperature cold.

Therefore, the existing toilets suitable for cold regions need to be improved.
