Description

Technical Field

[0001] The utility model relates to the field of feed fermentation, in particular to a fermentation device. Background Art

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to food for animals raised in agriculture or animal husbandry. Nowadays, fermentation equipment is needed to ferment the feed during feed production. The existing fermentation equipment mainly includes a fermentation tank, a stirring mechanism, a feed port, a discharge port, an exhaust pipe and an exhaust valve. When the feed is fermented in the fermentation tank for a long time, the feed will produce gas that accumulates inside the tank. When the air pressure inside the fermentation tank is too high, it is necessary to manually open the exhaust valve to discharge the accumulated gas in the fermentation tank from the exhaust pipe. However, when exhausting the air, it is necessary to manually check the air pressure in the fermentation tank and then open the exhaust pipe through the exhaust valve, which is inconvenient to use. In addition, the gas discharged from the fermentation tank will also contain harmful substances (such as odors, organic compounds, volatile compounds and particulate matter, etc.) and odor. If these gases are discharged into the atmosphere without treatment, it will cause air pollution, thereby affecting the air quality of the surrounding environment.

[0003] Therefore, it is necessary to invent a fermentation device. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fermentation device, including a fermentation tank, an exhaust pipe is installed at the upper end of the fermentation tank, a ring-shaped array of leakage holes is opened on the surface of the exhaust pipe, a sealing cover is movably connected to the outside of the upper end of the exhaust pipe, a protective outer tube is arranged outside the exhaust pipe and the sealing cover, a connecting pipe is installed on one side of the upper end of the protective outer tube, and a filter assembly is installed on the end of the connecting pipe away from the protective outer tube.

[0006] Based on the above characteristics: when the air pressure inside the fermentation tank is too high, the gas will push up the sealing cover through the exhaust pipe. At this time, the leakage hole will be exposed to the outside, and the gas will enter the protective outer tube through the leakage hole. When the air pressure inside the fermentation tank decreases and the sealing cover cannot be lifted, the sealing cover will move down to cover the leakage hole, so that the gas inside the fermentation tank cannot be discharged. Then the gas entering the protective outer tube will flow upward and finally be discharged through the connecting pipe. No manual operation is required. When the gas is discharged, the filter component can be used to filter the gas, which can not only remove harmful particles in the gas, but also adsorb and purify the gas, reduce the odor of the fermentation gas, and avoid polluting the surrounding environment.

[0007] Preferably, guide protrusions are symmetrically installed on both sides of the outer wall of the sealing cover, and a permanent magnet A is installed on the upper end of the sealing cover.

[0008] Based on the above features: the guide protrusion can guide and limit the sealing cover to make the sealing cover move vertically.

[0009] Preferably, guide grooves are provided on the inner walls of both sides of the protective outer tube, a partition is installed on the upper end of the protective outer tube, a permanent magnet B is installed on the lower end of the partition, and a ring-shaped array of through holes is provided on the surface of the partition.

[0010] Based on the above characteristics: when the gas enters the interior of the protective outer tube, the gas will flow upward through the through holes and through the partition.

[0011] Preferably, the connecting pipe is a tubular structure with openings at both ends, the connecting pipe is connected to the protective outer pipe via a bend, and an inner wall of the connecting pipe on a side away from the bend is provided with an internal thread.

[0012] Based on the above characteristics: the gas is introduced into the interior of the connecting pipe through the bent pipe, and then the gas will enter the interior of the filter component, and will be discharged to the outside after being filtered and adsorbed by the filter component.

[0013] Preferably, the filter assembly includes a cylinder and a first filter screen installed on the surface of the cylinder, the cylinder is filled with activated carbon particles, and a sealing end cap is installed at one end of the cylinder.

[0014] Based on the above characteristics: the gas can enter the cylinder through the first filter, and then the gas will be adsorbed and purified by the activated carbon particles, and finally the adsorbed and purified gas will be discharged through one end of the cylinder close to the sealing end cover.

[0015] Preferably, a fixing sleeve is installed on the outside of one end of the cylinder body close to the sealing end cover, an outer wall of the fixing sleeve is provided with an external thread, and a sealing plug is installed on one end of the cylinder body away from the sealing end cover.

[0016] Based on the above features: after the cylinder is inserted into the connecting pipe, the fixing sleeve is threadedly connected with the internal thread of the inner wall of the connecting pipe, and at the same time, the sealing plug can seal the end of the cylinder away from the sealing end cover.

[0017] Preferably, a second filter screen is installed in the middle of the sealing end cover, and a sealing ring is provided between the sealing end cover and the connecting pipe.

[0018] Based on the above features: the sealing ring can seal between the sealing end cover and the connecting pipe to avoid gas leakage caused by a gap between the two. The gas after adsorption and purification will be filtered through the second filter screen in the middle of the sealing end cover and then discharged.

[0019] The beneficial effects of the utility model are:

[0020] 1. Convenient automatic exhaust. When the air pressure inside the fermentation tank is too high, the gas will push up the sealing cover through the exhaust pipe. At this time, the leakage hole will be exposed to the outside, and the gas will enter the protective outer tube through the leakage hole. Then the gas will flow upward through the through hole through the partition, and the gas will be introduced into the connecting pipe through the elbow and discharged. When the air pressure inside the fermentation tank decreases and the sealing cover cannot be lifted, the sealing cover will move down to cover the leakage hole, so that the gas inside the fermentation tank cannot be discharged.

[0021] 2. The exhausted gas can be filtered and absorbed. There is a gap between the cylinder and the connecting pipe, and the gas can flow inside the connecting pipe through the gap. When the gas flows, it can enter the cylinder through the first filter screen, and then the gas will be adsorbed and purified by the activated carbon particles. Finally, the adsorbed and purified gas will be filtered through the second filter screen in the middle of the sealed end cover and then discharged. It can not only remove harmful particles in the gas, but also adsorb and purify the gas, reduce the odor of the fermentation gas, and avoid polluting the surrounding environment.

[0029] When the air pressure inside the fermentation tank 1 is too high, the gas will push up the sealing cover 4 through the exhaust pipe 2. At this time, the leakage hole 3 will be exposed to the outside, and the gas will enter the protective outer tube 5 through the leakage hole 3. Then the gas entering the protective outer tube 5 will flow upward and finally be discharged through the connecting pipe 6. No manual operation is required. When the gas is discharged, the filter component 7 can be used to filter the gas, which can not only remove harmful particles in the gas, but also adsorb and purify the gas, reduce the odor of the fermentation gas, and avoid polluting the surrounding environment.

[0030] Preferably, guide protrusions 41 are symmetrically installed on both sides of the outer wall of the sealing cover 4, and a permanent magnet A42 is installed on the upper end of the sealing cover 4.

[0031] The guide protrusion 41 can guide and limit the sealing cover 4 so that the sealing cover 4 can move vertically.

When the gas pressure is too low to lift the sealing cover 4, the permanent magnet B53 will push the permanent magnet A42 downward, so that the sealing cover 4 moves down to cover the leakage hole 3. When the gas enters the protective outer tube 5, the gas will pass through the through hole 54 through the partition 52 and flow upward.

[0034] Preferably, the connecting pipe 6 is a tubular structure with openings at both ends, and the connecting pipe 6 is connected to the protective outer pipe 5 via a bend, and an inner thread is provided on the inner wall of the connecting pipe 6 on a side away from the bend.

[0035] The gas is introduced into the interior of the connecting pipe 6 through the bent pipe, and then the gas will enter the interior of the filter assembly 7, and will be discharged to the outside after being filtered and adsorbed by the filter assembly 7.

[0036] Preferably, the filter assembly 7 includes a cylinder 71 and a first filter screen 72 installed on the surface of the cylinder 71 . The cylinder 71 is filled with activated carbon particles 73 . A sealing end cap 74 is installed at one end of the cylinder 71 .

When the gas flows, it can enter the cylinder 71 through the first filter screen 72, and then the gas will be adsorbed and purified by the activated carbon particles 73. Finally, the adsorbed and purified gas will be discharged through one end of the cylinder 71 close to the sealing end cover 74.

At the same time, the sealing plug 712 can seal the end of the cylinder 71 away from the sealing end cover 74 to prevent the activated carbon particles 73 in the cylinder 71 from falling off, and it is also convenient to replace the activated carbon particles 73.

[0040] Preferably, a second filter screen 741 is installed in the middle of the sealing end cover 74 , and a sealing ring 742 is provided between the sealing end cover 74 and the connecting pipe 6 .

The gas after adsorption and purification will be filtered through the second filter screen 741 in the middle of the sealing end cover 74 and then discharged.

[0042] The use process of the utility model is as follows: when the internal air pressure of the fermentation tank 1 is too high, the gas will push up the sealing cover 4 through the exhaust pipe 2.

Then the gas will pass through the through hole 54 to flow upward through the partition 52, and the gas will be introduced into the connecting pipe 6 through the elbow. There is a gap between the cylinder 71 and the connecting pipe 6, and the gas can flow inside the connecting pipe 6 through the gap. When the gas flows, it can enter the cylinder 71 through the first filter screen 72, and then the gas will be adsorbed and purified by the activated carbon particles 73. Finally, the adsorbed and purified gas will be filtered through the second filter screen 741 in the middle of the sealing end cover 74 and discharged. When the internal air pressure of the fermentation tank 1 is reduced and the sealing cover 4 cannot be lifted, the sealing cover 4 will move down to cover the leakage hole 3, so that the gas inside the fermentation tank 1 cannot be discharged.
