Embodiment 1

[0032] refer to Figure 1~5 , This embodiment provides an automatic exhaust device for a biogas pit, which can automatically discharge biogas when there is too much biogas generated in the biogas pit, and automatically shut down when the amount of biogas is too small. It includes an exhaust unit 100 and a connection unit 200; the specific exhaust unit 100 includes a valve body 101, a piston 102 located in the valve body 101, a sealing seat 103 connected to one end of the valve body 101, and a row connected to the other end of the valve body 101. The gas plate 104, the first air guide pipe 105 connected with the piston 102, and the cover plate 106 connected with the first air guide pipe 105; the valve body 101 is in the shape of a cylinder, which can connect the original exhaust port of the biogas digester and the external biogas pipeline, the piston 102 can slide on the valve body 101 along the axial direction of the valve body 101, the sealing seat 103 and the exhaust plate 1...

Embodiment 2

[0039] refer to Figure 1-9 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and the difference from the previous embodiment is: when the raw materials in the biogas digester react fully, more biogas is generated, and stable discharge is required, Then the present invention also includes the following devices; specifically, including a lifting member 205 located inside the biogas tank, the lifting member 205 is divided into a lifting plate 205a and a lifting protrusion 205b located at the center of the lifting plate 205a, and a sliding rod 206 is connected to the outside of the lifting plate 205a , the sliding rod 206 passes through the top plate 204 of the biogas tank, and the function of the lifting member 205 is to apply a thrust to the part of the second air guide pipe 202 located in the biogas tank, so that the piston 102 and the cover plate 106 are far away from the exhaust hole 104a to discharge biogas, wherein the...

Abstract

The invention discloses an automatic exhaust device for a biogas pond, which includes an exhaust unit, which includes a valve body, a piston located in the valve body, a sealing seat connected with one end of the valve body, and a sealing seat connected with the other end of the valve body. The exhaust plate, the first air guide pipe connected with the piston, and the cover plate connected with the first air guide pipe; the connection unit, including the exhaust pipe connected with the sealing seat, the exhaust pipe connected with the piston The second air guide pipe, and the external pipe connected with the exhaust plate, the exhaust pipe is installed on the top plate of the biogas tank and communicates with the inside of the biogas tank; the exhaust unit can be opened or closed automatically without manual intervention, that is, Automatically open when exhausting, automatically close when there is no biogas, and can also be adjusted to a normal open state to discharge biogas.

Description

technical field [0001] The invention relates to the field of biogas pits, in particular to an automatic exhaust device for biogas pits. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. Because this gas was first found in swamps, lakes, and ponds, people called it biogas. With the development of China's biogas science and technology and the promotion of rural household biogas, according to local use requirements and conditions such as temperature and geology, household biogas digesters include hydraulic pools with fixed arch covers, hydraulic pools with large uncovered covers, and pipe-hanging pools. Hydraulic pool, meandering cloth hydraulic pool, top return hydraulic pool, separated floating cover pool, semi-plastic pool, all-plastic pool and tank pool. There are various forms, but the structure of the vent hole is single, an...
