Problems solved by technology

[0003] At present, the biogas production of biogas digesters is usually limited, for example, it will affect the biogas production with seasonal and diurnal temperature changes
Under normal circumstances, when the temperature in the biogas digester is greater than 15°, the biogas can be produced normally, and when the temperature in the biogas digester is lower than 15°, the biogas production rate is very low, or even no longer produces biogas
[0004] Moreover, at present, people generally choose to use gas storage tanks or gas storage bags to collect the biogas produced by the biogas digester, which usually has the problem of inconvenient gas collection, and the gas storage tank takes up a lot of space
[0005] Because the existing biogas production system has the above-mentioned deficiencies, those skilled in the art still need to develop a new biogas production system to solve the problems of low biogas production rate and inconvenient gas collection in existing biogas digesters. Many deficiencies, so as to provide more clean energy for human beings, and rapidly promote the sustainable development of the economy

Embodiment 1

[0036] Such as figure 1 and 2 As shown, a biogas production system of a biogas digester with a driving mechanism includes a biogas digester 1, a biogas digester 1 includes a pond body 1a capable of producing biogas, a pond cover 1b hinged on the upper part of the pond body 1a and a connecting pipe 2, the pond The body 1a is provided with an electric heating tube 3, one end of the connecting tube 2 passes through the pool cover 1b and communicates with the pool body 1a, and the connecting tube 2 and the pool cover 1b are kept sealed, and the other end of the connecting tube 2 is connected with a storage device, The pool body 1a is also provided with a control mechanism that can automatically turn on the electric heating tube 3 when the temperature in the pool body 1a is lower than the set value.

[0037] Specifically, a mounting hole is opened on the pool cover 1b, and the connecting pipe 2 passes through and is fixed in the mounting hole. A sealing ring is fixed on the connec...

Embodiment 2

[0047] The structure and principle of this embodiment are basically the same as that of the first embodiment, the difference is that in the first embodiment, the holding mechanism includes a pressing plate 11, a spring 12 and a nut 13; while in the second embodiment, the holding mechanism It includes a nut 13 and an annular pressure plate 11 , the pressure plate 11 is sheathed on the column 6 , and the nut 13 is screwed to the upper section of the column 6 . The lower plate surface of the pressing plate 11 can always be pressed and held on the uppermost air storage bag 5 under the action of its gravity, and the pressing plate 11 can move upwards with the swelling of the air storage bag 5 at the same time. And moving downward, the volume of the air storage bag 5 is always in the minimum state, thereby reducing the occupied space of the air storage bag 5 . Nut 13 is screwed on the upper end of column 6 with hand, just can prevent that pressing plate 11 breaks away from column 6....

Embodiment 3

[0049] The structure and principle of the present embodiment are basically the same as those of the first embodiment, the difference is that in the first embodiment, the driving mechanism includes a bracket 16, a shaft coupling 15 and a motor 14; and in the third embodiment, as Figure 5As shown, the drive mechanism includes a driving gear 25, a driven gear 26, a chain 27 and a motor 14, the driving gear 25 is fixed on the output shaft of the motor 14 by a flat key, and the driven gear 26 is fixed on the upper section of the column 6 by a flat key , the chain 27 is arranged between the driving gear 25 and the driven gear 26, the motor 14 is fixed on the base 4 through a fixing plate, and the fixing plate is fixed on the base 4 by screws. By controlling the positive and negative rotation of the motor 14, the driving gear 25 can be driven to rotate forward and reverse, so that the vertical column 6 can be rotated positively and negatively through the chain 27, and finally the pos...

Abstract

The invention provides a marsh gas production system of a marsh gas tank with a drive mechanism, belongs to the technical field of marsh gas, and solves the technical problems of the existing marsh gas production system such as low gas production efficiency, inconvenient gas collection, large occupied space of a storage device and the like. The marsh gas production system of a marsh gas tank with a drive mechanism comprises a marsh gas tank, wherein the marsh gas tank comprises a tank body in which marsh gas can be produced, a tank cover hinged at the upper part of the tank body and a connecting tube, wherein an electric heating tube is arranged in the tank body; one end of the connecting tube is communicated with the tank body through the tank cover; the connecting tube and the tank cover keep sealed; the other end of the connecting tube is connected with a storage device; and a control mechanism capable of automatically starting the electric heating tube when the temperature in the tank body is lower than a set value is further arranged in the tank body. The marsh gas production system provided by the invention has the advantages of high gas production efficiency, convenient gas collection and small occupied space of the storage device.

Description

technical field [0001] The invention belongs to the technical field of biogas, and relates to a biogas production system, in particular to a biogas production system of a biogas pit with a driving mechanism. Background technique [0002] With the development of the economy, people's excessive use of non-renewable resources has made countries face severe challenges to energy issues, and energy has become an important guarantee for sustainable economic development in various countries. Biogas is a kind of clean energy in the rural areas of our country. It is produced by fermenting the waste straw of crops. It can be used for boiling water and cooking. It can save a lot of natural resources such as coal and wood for human beings. The biogas will not pollute the environment and has high thermal efficiency. [0003] At present, the biogas production of biogas digesters is usually subject to certain restrictions, for example, it will affect the biogas production with seasonal and...
