Description

Technical Field

[0001] This utility model relates to the field of biogas anaerobic dry fermentation technology, specifically a biogas anaerobic dry fermentation device. Background Technology

[0002] Anaerobic dry fermentation of biogas is a type of biogas fermentation technology. It is mainly based on the principle that organic waste produces biogas (mainly methane and carbon dioxide) through the decomposition and metabolism of microorganisms under anaerobic conditions.

[0003] The prior art discloses a silkworm excrement anaerobic dry biogas fermentation device (application number CN200920265009.X), aiming to provide a harmless fermentation processor specifically for silkworm farmers, featuring a closed structure to prevent the spread of pathogens, a simple structure, and the ability to improve the silkworm rearing environment and solve the problems of pathogen transmission and odor pollution from feces. It comprises a feeding system, a discharging system, and a fermentation chamber. The feeding system includes a feeding pipe and a movable cover plate, while the discharging system includes a discharging pipe and a discharging valve. The feeding pipe is sealed and welded to the tank body, and the height of the feeding pipe is less than the radius of the tank body, thus forming a biogas fermentation tank capable of dry fermentation. When feeding silkworm excrement into the feeding pipe, it accounts for approximately 20%–40% of the weight, and 60%–80% of the weight of dilution water needs to be added simultaneously to ensure the effectiveness of dry biogas fermentation. After fermentation, the valve is opened to pour out the biogas fertilizer and treated water from the discharging port.

[0004] The above-mentioned cleaning of the tank requires the use of tools to observe the inside of the tank before cleaning the inner wall surface, which makes cleaning the inner wall surface of the tank quite troublesome and requires a lot of time. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A biogas anaerobic dry fermentation device includes a fermentation device 1 and a limiting cover plate 4. A storage shell 2 is installed on the bottom surface inside the fermentation device 1, and a connecting rod 3 is installed on the upper end of the storage shell 2. The limiting cover plate 4 is threadedly connected to the upper end of the fermentation device 1.

[0025] The fermentation device 1 includes a support rod 11, a protective shell 12, and a limiting component 13. The support rod 11 is installed in the middle position of the limiting component 13, and the protective shell 12 is installed at the lower end of the support rod 11.

[0026] The limiting component 13 includes a fermentation shell 131, a helical spring 132, a connecting rod 133, a connecting block 134, a metal insert 135, a metal support block 136, and a filter plate 137. The filter plate 137 is movably connected to the top surface of the metal support block 136, and the metal support block 136 is movably connected to the bottom surface of the storage shell 2. The storage shell 2 is located inside the fermentation shell 131. Pushing the storage shell 2 downwards connects the bottom surface of the storage shell 2 with the top surface of the filter plate 137, thereby determining the position of the storage shell 2. The metal support block 136 is installed at the lower end inside the fermentation shell 131. The support rod 11 is installed in the middle position of the fermentation shell 131. The protective shell 12 is movably connected to the lower end of the fermentation shell 131. The support rod 11 can support the fermentation shell 131, while the protective shell 12 can protect the safety of the fermentation shell 131. The connecting blocks 134 are fixedly connected to the lower end of the fermentation shell 131. There are four connecting blocks 134. Connecting blocks 134 are distributed at the lower end of the fermentation shell 131. Connecting blocks 134 are fixed at the lower end of the fermentation shell 131. Limiting cover 4 is threadedly connected to the upper end of the fermentation shell 131. Limiting cover 4 is located above connecting rod 2 3 and above storage shell 2. Pushing the limiting cover 4 downward slightly, the limiting cover 4 and the upper end of the fermentation shell 131 are threadedly connected, which can protect the fermentation shell 131 and the storage shell 2. The helical spring 132 is fixedly connected to the metal insert 135 outward. On one side, a metal insert 135 is inserted into the outward end of a metal support block 136. The metal insert 135 is also inserted into the lower end of a fermentation shell 131. The metal insert 135 is inserted into both the fermentation shell 131 and the metal support block 136, thereby determining the positions of the metal support block 136 and the fermentation shell 131, facilitating the disassembly and replacement of the metal support block 136. The metal insert 135 is fixedly connected to the inward end of a connecting rod 133, and the metal insert 135 is slidably connected to the inner wall surface of a connecting block 134.

[0027] When in use, push the metal plug 135 into the interior of the connecting block 134. The metal plug 135 slides on the inner wall surface of the connecting block 134, which can determine the position of the connecting block 134.

[0028] When the metal insert 135 slides on the inner wall surface of the connecting block 134, the metal insert 135 can drive the connecting rod 133 to move, thereby determining the position of the connecting rod 133, and then pushing the left side surface of the coil spring 132 to connect with the right side surface of the metal insert 135.

[0029] A limiting cover plate is threadedly connected to the outer surface of the connecting block 134. The limiting cover plate slides on the surface of the connecting rod 133. At the same time, the limiting cover plate and the outer surface of the connecting block 134 are threadedly connected, thereby determining the position of the helical spring 132.

[0030] The metal support block 136 is pushed to move downward, which in turn drives the filter plate 137 to move downward. The metal support block 136 slides on the inner wall surface of the fermentation shell 131, thereby pushing the metal insert block 135 to slide on the lower inner wall surface of the fermentation shell 131.

[0031] When the metal insert 135 moves, it can push the helical spring 132, so that the helical spring 132 can be compressed between the limiting cover plate and the metal insert 135.

[0032] When the metal support block 136 is inserted into the lower end of the fermentation shell 131, the helical spring 132 begins to rebound. The helical spring 132 can push the metal insert 135 against the inner wall surface of the connecting block 134, so that the metal insert 135 is inserted into the position of the metal support block 136 and the fermentation shell 131, thereby determining the position of the metal support block 136.

[0033] Push the storage housing 2 downwards, and connect the bottom surface of the storage housing 2 with the top surface of the filter plate 137.

[0034] Push the limiting cover 4 downward to connect the limiting cover 4 with the top surface of the fermentation shell 131. At the same time, a hole is opened in the middle of the limiting cover 4, and a ventilation pipe is threadedly connected in the middle of the limiting cover 4 and a ventilation pipe is threadedly connected to the bottom surface of the fermentation shell 131.

[0035] The storage shell 2 can carry out fermentation of materials. The gas from anaerobic dry fermentation is transported through the filter plate 137. At the same time, the gas can be transported through the ventilation pipe connected in the middle of the limiting cover plate 4 and the ventilation pipe on the bottom surface of the fermentation shell 131.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
