Conical surface closed excrement fetching port

Abstract

The invention discloses an excrement fetching port of a conical surface closed or spiral or buckle fixed connection structure, and relates to an excrete fetching port device with closed type excrete fetching characteristic. Port joint surfaces for performing butting are mutually closed conical surfaces; and the closing state of the port joint surface is kept by the spiral fixed connection or buckle fixed connection structure of two ports. Closed excrete fetching is realized by applying the excrete fetching port provided by the invention; the excrement fetching port has good sealing property and high reliability and is quick and convenient to operate; and even in case of residual excrete flow, the flow range is small, and the cleaning is convenient, so that the closed excrete fetching has the advantage of environmental friendliness and an more ideal effect is achieved.

Description

technical field [0001] The invention relates to a device for taking and transporting stool and a facility for storing stool, in particular to a stool collection interface device with a closed stool collection feature. Background technique [0002] Chinese patent application, application number: 00113266.0, date of publication: October 10, 2001, discloses a kind of closed stool extraction method and the technical scheme of the collection and storage facility and transportation device supporting it, one of the core technical contents of the scheme: "The free end of the excrement pipe of the excrement tanker is equipped with a pipe joint device that can be adapted to the excrement outlet of the storage facility." It provides technical support for cleaning and environmental protection, and has the characteristics of outstanding technological progress. [0003] But this scheme does not provide clear concrete structure to pipe joint device, also does not give the specific structu...

Problems solved by technology

[0004] In fact, if you want to implement closed feces retrieval, no matter whether the feces storage and transportation device is a feces tanker or a feces tanker or other structure, whether it is powered or manpower driven, whether it is positive pressure fetching Stool or negative pressure stool, the implementation of the closed collection storage facility and the interface device of the stool storage and transportation device should not only consider its specific implementation, but also meet the aforementioned interface adaptation with the stool outlet channel of the collection container, which can prevent In addition to the characteristics of liquid and gas leakage, its reliability, quick operation and convenience cannot be ignored; it even includes the stool removal process. If there is drooling in the pipeline, it is necessary to do a special cleaning work on the interface with drooling. The workload of this cleaning work should be reduced or even avoided as much as possible, and it should be fully considered. However, the background technology obviously lacks specific technologies for these problems. Consideration of solutions
