Harmlessness toilet tools

Abstract

The invention relates to a harmless lavatory, comprising a commode, a fecal treatment system communicating with the lower part of the commode, a deodorizing system for removing odor generated by the fecal treatment system, a water cycle treatment system, and an electric control system for automatically controlling the fecal treatment system, the deodorizing system and the water cycle treatment system, wherein the fecal treatment system comprises a crushing cylinder communicating with the bottom of the commode, a drying cylinder body, a front bearing seat and a back bearing seat arranged at two ends of the drying cylinder body and a main shaft connected with a power unit; the front end of the front bearing seat is provided with a feeding cylinder; the main shaft is arranged inside the drying cylinder via the front and the rear bearing seats and extended inside the feeding cylinder and the crushing cylinder; the main shaft sections in the crushing cylinder, the feeding cylinder and the drying cylinder body are respectively provided with a crushing knife, a feeding impeller and a spiral propeller; and the inner wall of the crushing cylinder is provided with a hollow cavity. The i harmless lavatory can rapidly and completely oven-dry feces slurry and perform harmless treatment, with low failure rate.

Description

technical field [0001] The invention relates to a feces processing device, in particular to a harmless toilet. Background technique [0002] The harmless treatment of feces is currently recognized as a technical problem, especially in transportation such as trains, urban rails, ships, and long-distance passenger vehicles. This technical problem needs to be solved urgently. [0003] Chinese Patent Document No. CN1433979 discloses an environment-friendly excrement processing machine, which includes a toilet, a stool connecting cylinder, a toilet tank, a material cylinder body and a drying cylinder body. A push plate is inserted in the toilet tank, and the push plate passes through a transmission mechanism. Connected with the power device, the main shaft connected with the power device is installed in the drying cylinder body, the feeding impeller is installed in the material cylinder body, the knife holder is installed in the drying cylinder body, and the heater is installed o...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned prior art also has the following disadvantages: first, when the drying drum body heats and dries the dung slurry, or the drying is not thorough, it is not conducive to deodorization, and it is not conducive to collection as organic fertilizer; , that is, dry manure loses its fertilizer effect and cannot be collected and utilized as organic fertilizer

Secondly, in the knife holder in the drying cylinder, the two shafts on which the knife is installed are parallel to the main axis between them, which cannot evenly throw the dung slurry to the inner wall of the drying cylinder and realize the function of pushing forward, resulting in the feed port often Agglomerated dung slurry appears, which cannot effectively dry the dung slurry

Secondly, the inner wall of the existing drying cylinder is smooth, it is not easy to adhere to the dung slurry and the adhesion area is small, and the heating effect and heat energy utilization rate of the drying cylinder body are poor, which is not conducive to rapid drying and energy saving.

Again, when hard objects such as long fibers or coins fall into the scrap housing, the scrap housing is often damaged or entangled with the crushing knife in the scrap housing, so that the toilet can not work normally and can only wait for manual processing. After that, it can be used normally, so the failure rate of the toilet set in the prior art is high, which greatly affects its normal use
