Embodiment 1

[0039] Such as Figure 1 to Figure 4 As shown, the biogas digester with high safety is composed of a pond body 1, a pond cover 2, a fermentation barrel 3, a sealing plate 4, a motor 5, a connecting pipe 6, a plug 7 and the like.

[0040] Wherein, the pool body 1 is barrel-shaped, and its top is open and its bottom is closed. The pool cover 2 is barrel-shaped, and the pool cover 2 is set on the pool body 1 and the two are fixed together. In this embodiment, the pool body 1 and the pool cover 2 are hermetically fixed together by a tight fit. Such as figure 1 As shown, the pool cover 2 is provided with an air outlet 2a that communicates the inner cavity of the pool body 1 with the outside world, and in actual use, the air outlet 2a is connected to the user pipeline through a valve (not shown).

[0041] The fermenter 3 is in the shape of a straight barrel, and the fermenter 3 is vertically arranged in the pool body 1 . Such as figure 1 As shown, the bottom of fermenter 3 is c...

Embodiment 2

[0049] The structure and principle of the present embodiment two are basically the same as those of the first embodiment, except that the transmission mechanism includes a driving wheel fixed on the main shaft of the motor 5 and a driven wheel fixed on the screw mandrel 9, and the driving wheel passes through The timing belt is connected with the driven wheel.

Embodiment 3

[0051] The structure and principle of this third embodiment are basically the same as that of the first embodiment, except that the outer wall of the connecting pipe 6 has an annular shoulder, and the sealing structure includes an annular locking groove and a design on the upper end surface of the annular shoulder. The ring seal is placed in the ring groove, and the two ends of the ring seal are against the bottom wall of the ring groove and the inner top wall of the pool cover 2 respectively.

Abstract

The invention provides a biogas digester with high safety, and belongs to the technical field of biogas. The biogas digester with the high safety comprises a biogas digester body and a digester lid which is fixedly arranged at the top of the biogas digester body, the digester lid is provided with an air outlet, the biogas digester body is vertically provided with a fermentation bucket, the digester lid is provided with a slag discharging opening opposite to the fermentation bucket in a penetrating mode, the digester lid is fixedly provided with a sealing plate which seals the upper end opening of the slag discharging opening in a detachable mode, the inner bottom wall of the biogas digester body is fixedly provided with a motor, the motor is connected with the bottom of the fermentation bucket through a lead screw-nut transmission mechanism so as to drive the fermentation bucket to abut against the digester lid or away from the digester lid, when the fermentation bucket abuts against the digester lid, the top wall of the fermentation bucket abuts against the inner top wall of the digester lid so as to form sealing, the biogas digester body is vertically and fixedly provided with a straight pipe-shaped connecting pipe, the upper end of the connecting pipe penetrates through the digester lid, the lower end opening of the connecting pipe is internally fixedly provided with a cylindrical drain plug, and a power wire of the motor penetrates through the drain plug and the upper end opening of the connecting pipe in sequence. The biogas digester with the high safety has the advantages of being capable of lowering biogas waste in a deslagging process.

Description

technical field [0001] The invention belongs to the technical field of biogas, and relates to a biogas digester, in particular to a biogas digester with high safety. Background technique [0002] Biogas can be used not only as energy for lighting, but also as gas energy for cooking. Since the main raw material for generating biogas comes from crops, it can greatly reduce the consumption of forest resources and coal-fired resources. Therefore, biogas is a popular energy-saving technology that has been popularized and applied in recent years and is widely used in rural areas. [0003] Existing biogas digesters use traditional building materials such as bricks, sand, lime, and cement. Although the method of building a biogas digester is relatively simple, the daily maintenance requirements after completion are very high, and there are many faults during use, for example, leakage Gas is the most common fault in the use of biogas digesters. Often due to poor sealing between the ...
