Problems solved by technology

Due to the high cost of the existing straw treatment methods, it will affect the sowing of the next season's crops
Burning straw on the spot has become a helpless choice, which not only causes a waste of resources, but also brings serious environmental pollution problems
If straw and biogas can be effectively combined to develop household biogas, it will not only save renewable high-quality biomass resources, but also protect the environment. There are problems such as the straw is easy to float, cannot be fully fermented, and is not easy to produce slag.

Embodiment 1

[0029] A hydraulic biogas digester with automatic feeding and discharging, such as figure 1 As shown, it includes a fermentation tank 1 and a feed pipe 2 and a hydraulic room 3 communicating with the body of the fermentation tank 1, and also includes an automatic feeding and discharging device 4 that traverses the feed pipe 2, the fermentation tank 1 and the hydraulic room 3, This automatic feeding and discharging device 4 can be disassembled and separated according to the situation or installed in the biogas digester; the automatic feeding and discharging device 4 includes a pipe chain conveyor belt 5 and a driving device 6; the pipe chain conveyor belt 5 (such as Figure 5 shown) includes a delivery pipe 51 and a transmission chain 52 worn in the delivery pipe; the transmission chain 52 is composed of a plurality of end-to-end chains 521, and a plurality of transmission plates 522 are equidistantly arranged on the transmission chain 52, so The transmission plate 522 fits the...

Embodiment 2

[0035] The biogas digester described in embodiment 2 (such as figure 2 shown) is substantially the same as that described in Embodiment 1, the difference is that a communicating room 10 is set, and the communicating room 10 communicates with the hydraulic room 3 through the communicating device 10, and the bottom surface of the communicating room 10 and the bottom surface of the hydraulic room 3 The heights are the same, one end of the connecting device 11 is set at the bottom of the communicating room 10 , and the other end is set at the bottom of the water pressure room 3 . The floating ball 63 is located in the communication room 10, and the lever 62 is in a bent shape, connecting the floating ball 63 and the one-way gear 61 fixed on the outer wall of the hydraulic room 3. Other structures and methods of use are the same as in Example 1.

[0036] Both embodiment 1 and embodiment 2 rely on the power generated by the lifting of the floating ball to drive the transmission ch...

Abstract

The invention relates to a hydraulic biogas digester with automatic feeding and discharging and its automatic feeding and discharging method, belonging to the field of renewable energy fermentation, including a fermentation tank, a feeding pipe connected thereto, a hydraulic room, and a crossing feeding pipe , The automatic feeding and discharging device between the fermentation tank and the hydraulic pressure room, the automatic feeding and discharging device includes a pipe chain conveyor belt and a driving device; the pipe chain conveyor belt includes a conveying pipe and a transmission chain, and the driving device drives the transmission chain for transmission; the pipe chain type The conveyor belt is extruded to form a first bending end and a second bending end, and the first bending end is clamped at the connection between the fermentation tank and the feeding pipe, and a feeding port is provided on it; the inside of the second bending end A driving device is provided, and a discharge port is provided on the outside; micro-holes are provided on the conveying pipe. The biogas digester not only effectively alleviates the dependence of household biogas digesters on young and middle-aged labor, but also expands the source of biogas fermentation materials through the use of straw, and at the same time reduces the environmental pollution caused by straw burning. In terms of energy saving and emission reduction play a major role.

Description

technical field [0001] The invention relates to the technical field of renewable energy fermentation, in particular to a hydraulic biogas digester with automatic feeding and discharging and a method for automatically feeding and discharging materials. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation and decomposition of organic matter in an anaerobic environment under certain temperature, humidity, and pH conditions. Biogas fermentation widely exists in natural environments such as lakes, swamps, open-air toilets, etc. However, as society With the development of the country, people continue to try to artificially produce biogas by building biogas digesters, which is especially common in vast rural areas. Biogas is produced by fermenting domestic garbage, human and animal manure, etc., and the prepared biogas can be used in production and life, which can not only save energy , but also improve the rural environment. With the develo...
