Description

Technical Field

[0001] The invention relates to the technical field of anaerobic sealed fermentation equipment, in particular to an anaerobic sealed fermentation tank for mixed biological feed. Background Art

[0002] Anaerobic fermentation of organisms is a commonly used processing method in the biomedical engineering industry. In order to ensure the anaerobic sealed fermentation of mixed biological feed, anaerobic sealed fermentation equipment is often required. The invention patent with patent application number CN201210476611.4 discloses an anaerobic fermentation tank. By adding a liquid retaining device, the fluid is discharged from the middle layer or upper layer of the anaerobic fermentation tank to the bottom layer of the tank body through the agitators and then hits the liquid retaining device, and generates a tumbling motion of the fluid and returns to the middle layer, upper layer or the inner wall of the anaerobic fermentation tank, thereby avoiding the precipitation of solid matter. The invention patent with patent application number CN200910060105.5 discloses a mobile anaerobic fermentation container. During and after movement, the non-return device can still perform stable and reliable actions, so that the anaerobic environment in the container is always maintained, and anaerobic fermentation continues, thereby achieving the goal of continuing to effectively carry out anaerobic fermentation during movement. The purpose is to reliably maintain the anaerobic environment in the container during and after movement, so that anaerobic fermentation can continue, and the fermented materials can be transported over long distances at room temperature and without adding preservatives, and stored for a long time without corruption, production of toxic substances, or leakage and contamination of the container. According to the technical solution disclosed therein, the existing anaerobic sealed fermentation equipment, when in use, on the one hand, cannot effectively maintain the stability of the fermentation temperature, and is prone to reducing the fermentation safety due to high or low temperature; on the other hand, it cannot effectively ensure that anaerobic bacteria are transported in a completely anaerobic environment, and is prone to brief contact with air during transportation, which is not conducive to ensuring the safety of anaerobic bacteria; on the other hand, before each fermentation work, a large amount of inert gas is often required, and the oxygen involved in the raw materials is prone to incomplete deoxygenation in the fermentation tank, which is in turn not conducive to ensuring the growth safety of anaerobic bacteria and fermentation efficiency.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. During the fermentation process of the mixed biological feed anaerobic sealed fermentation tank, the motor drives the rotating rod to rotate through the main shaft. The temperature control switch turns on the water pump and the heating wire according to the temperature in the tank. The water pump extracts the water in the inner cavity and pumps it to the inner side of the conduit. After being heated by the heating wire, it is passed into the inner side of the inner cavity again. When the main shaft drives the rotating rod to rotate, the fermentation raw materials in the tank are heated by the hot water in the inner cavity, which improves the heating speed and uniformity, and effectively ensures the uniform mixing of the raw materials. When the temperature in the tank is high, the temperature control switch turns on the water pump and the heating wire turns on the heating wire. The switch turns on the electric valve and the fan, and the water pump draws the heat-absorbing water out from the inner side of the inner cavity and then passes it into the inner side of the conduit. The fan filters the air through the filter and flows it inside the sleeve, effectively cooling the conduit. When the cooled water flows in the inner cavity, the raw materials in the tank are cooled by the rotating rod, which can effectively ensure the temperature stability in the tank, thereby ensuring the high efficiency and stability of anaerobic fermentation. At the same time, during the heating and cooling process, the tank is prevented from exchanging substances with the outside world, and the oxygen-free environment of the tank is protected from being destroyed.

[0016] 2. When the mixed biological feed anaerobic sealed fermentation tank is in use, after the oxygen in the tank body is completely exhausted, the material bottle is inserted into the inner side of the jacket, and the bottom of the material bottle is sealed on the inner wall of the jacket. The bayonet seals the bottom of the material bottle under the elastic force of the spring to prevent the material bottle from loosening. The guide rods on the one-way valve 2 in the material bottle and the jacket squeeze each other, so that the two one-way valves 2 are pushed open under the squeezing of the guide rods, so that the material bottle is connected to the tank body through the jacket, and the anaerobic bacteria in the material bottle are poured into the inner side of the tank body. The inert gas in the tank body enters the inner side of the material bottle at the same time. When the material bottle is pulled out, the positive pressure environment in the tank body is used to prevent air from entering the inner sides of the material bottle and the jacket at the moment when the material bottle and the jacket are separated. After separation, the material bottle and the jacket are respectively sealed by the one-way valve 2. The inert gas in the material bottle is used to prevent the anaerobic bacteria from coming into contact with the air when the anaerobic bacteria are added thereto, thereby ensuring the safe transportation of the anaerobic bacteria.

[0017] 3. When the mixed biological feed anaerobic sealed fermentation tank is fermenting, the raw materials are first added to the inner side of the tank body, and then the cover is sealed on the top of the tank body, and then the solenoid valve is opened. The carbon dioxide in the gas tank enters the deaerator through the solenoid valve, and then enters the inner side of the tank body through the one-way valve. The air on the top of the tank body is discharged outward through the exhaust pipe, and then the exhaust pipe is closed, and then the air pump and the solenoid valve are opened. The air pump sucks the carbon dioxide in the tank body and pumps it to the inner side of the gas tank. After deoxygenation through the sponge iron in the deaerator tank, the carbon dioxide is introduced into the inner side of the tank body. The circulating flow of carbon dioxide is used to completely purify and remove the oxygen remaining in the gap between the raw materials in the tank body, ensuring that the tank body is completely in an oxygen-free environment. The carbon dioxide introduced into the tank body makes the tank body in a high-pressure environment higher than the atmospheric pressure. In the environment, the piston in the sleeve is pushed upward by the air pressure and is located in the middle of the sleeve. When the tank leaks, the piston squeezes the button group downward, thereby opening the solenoid valve to replenish carbon dioxide into the tank, ensuring a positive pressure environment inside the tank, preventing air from entering the tank through the leak, and ensuring the safety of the anaerobic fermentation work of the tank. At the same time, the warning light is turned on to alarm so that personnel can check the tank and repair the leak in time. The carbon dioxide generated during the anaerobic fermentation process increases the air pressure in the tank, thereby causing the piston to squeeze the button group upward, thereby opening the air pump and passing carbon dioxide into the inside of the gas tank to replenish carbon dioxide in the gas tank to ensure the use of carbon dioxide. It can automatically replenish carbon dioxide or other inert gases and reduce the consumption of inert gases. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the warning light 35 is turned on to alarm so that personnel can check the tank body 1 and repair the leak in time. The carbon dioxide generated during the anaerobic fermentation process increases the air pressure in the tank body 1, thereby The piston 33 presses the button group 34 upward, thereby turning on the air pump 20, and passing carbon dioxide into the inner side of the gas tank 16 to replenish carbon dioxide in the gas tank 16, so as to ensure the use of carbon dioxide, automatically replenish carbon dioxide or other inert gases, and reduce the consumption of inert gas.
