Description

Technical Field

[0001] The utility model relates to the technical field of fermentation, in particular to a trough type fermentation partition aeration system. Background Art

[0002] A tank fermentation aeration device is a device used in biological fermentation processes, usually consisting of a tank reactor and an aeration system. The tank reactor is used to contain the fermented material, while the aeration system provides the oxygen required for the biological process by injecting gas, usually air or oxygen, into the reactor. This device is often used in fields such as bioengineering, food and beverage industry, to produce yeast, bacteria, enzymes and other biological products.

[0003] A Chinese patent discloses an aeration device for tank fermentation of organic waste (publication number: CN212857096U). The device is provided with an air guide pipe, a card cover, an aeration hole, an aeration pipe, a dirt blocking net, a floating ring and a closed water ring. When aeration is stopped, as the air pressure inside the card cover decreases, sewage from the outside flows in through the dirt blocking net, and then the sewage rises, and the water level enters the air guide pipe. Then the floating ring in the air guide pipe slides on the surface of the aeration pipe through the closed water sleeve, and then the floating ring drives the closed water ring to fit closely with the upper surface of the inner wall of the cavity, so that the sewage is blocked and will not continue to be poured in. This method can play a good role in preventing water from pouring in, so that sewage will not enter the aeration pipe when it is used, and it will not be blocked when used for a long time. However, there are still the following defects in the device:

[0004] The dirt-blocking net in the prior art can only intercept larger debris in sewage, while some smaller particles may pass through the gaps on the surface of the dirt-blocking net under the action of water pressure and enter the interior of the card cover. These debris particles will accumulate at the bottom of the card cover. After a long period of accumulation, they may block the bottom of the air duct and affect the output airflow of the aeration device. Therefore, a trough-type fermentation partition aeration system is proposed to solve the above problems. Utility Model Content

[0005] The technical problems to be solved by the utility model are as follows: some smaller particles may pass through the gaps on the surface of the dirt-blocking net and enter the interior of the card cover under the action of water pressure, and these debris particles will accumulate at the bottom of the card cover. After a long period of accumulation, they may block the bottom of the air duct and affect the output airflow of the aeration device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-6 As shown, a tank-type fermentation partition aeration system includes a conveying mechanism 1, an aeration mechanism 2 is arranged on the top of the conveying mechanism 1, and the conveying mechanism 1 includes a main pipeline 101; wherein the aeration mechanism 2 includes a mounting head 201, a connection port 202 is provided in the middle of the top of the mounting head 201, an aeration pipeline 203 is connected to one end of the side of the mounting head 201, and an air outlet 204 is provided at the bottom of the aeration pipeline 203 and at one end away from the mounting head 201; wherein the inner portion of the aeration pipeline 203 A baffle 205 is slidably connected to the wall and located above the air outlet 204. The baffle 205 is L-shaped as a whole. A bearing 206 is fixedly installed in the middle of one side of the baffle 205. A screw 207 is rotatably connected to the inner side of the bearing 206. A connecting sleeve 209 is threadedly sleeved on the outer wall of the screw 207. Among them, a waterproof rubber sleeve 208 is sleeved on the outer wall of the screw 207. One end of the waterproof rubber sleeve 208 is fixedly connected to the baffle 205, and the other end of the waterproof rubber sleeve 208 is fixedly connected to the connecting sleeve 209. Figure 2-Figure 3 As shown, the waterproof rubber sleeve 208 is made of silicone material and is used to prevent the surface of the screw 207 from rusting;

[0031] The inner wall of the aeration pipe 203 and above and below the connecting sleeve 209 are provided with a slide groove 211, and the inner sides of the two slide grooves 211 are fixedly connected with a spring 210, and the other end of the spring 210 is fixedly installed with the connecting sleeve 209. Figure 3 As shown, the spring 210 pushes the connecting sleeve 209 and the inner screw 207 to move, thereby driving the plate 205 to block the air outlet;

[0032] The end of the screw rod 207 located away from the bearing 206 is fixedly connected to a connecting rod 212, and the other end of the connecting rod 212 is fixedly connected to a movable block 213. The top and bottom ends of the movable block 213 are fixedly connected to a limit shaft 214. The outer wall of the connecting rod 212 is movably sleeved with a rotating sleeve 215. The middle part of the inner wall of the rotating sleeve 215 is provided with a connecting groove 216. The inner middle part of the connecting groove 216 is slidably connected to the movable block 213, and the inner ends of the connecting groove 216 are slidably connected to the limit shaft 214. Figure 4-Figure 5 As shown, when the limiting shaft rotating sleeve 215 rotates, the connecting groove 216 pushes the limiting shaft 214 to rotate the movable block 213, and the movable block 213 can slide in the connecting groove 216;

[0033] The outer wall of the rotating sleeve 215 is rotatably connected to the inner wall of the aeration pipe 203. The outer wall of the rotating sleeve 215 is also fixedly connected to a sealing ring. One end of the rotating sleeve 215 passes through the aeration pipe 203 and is fixedly connected to a knob 217. Figure 2 , Figure 4 As shown, the sealing ring fills the gap on the side of the rotating sleeve 215 to prevent external sewage from entering the interior of the aeration pipe 203;

[0034] The conveying mechanism 1 also includes a shunt pipe 102, one end of which is connected to the main pipe 101, and a bracket 105 is connected to the bottom of the shunt pipe 102, and a bolt 104 is threadedly connected to the top of the bracket 105. The end of the bolt 104 is threadedly connected to the outer wall of the shunt pipe 102, and a plurality of support pipes 103 are connected to the top of the shunt pipe 102, and the top of the support pipe 103 is fixedly connected to the mounting head 201, and the inside of the support pipe 103 is connected to the connecting port 202, such as Figure 6 As shown, the main pipeline 101 is connected to the Roots blower in the control unit. The use of the Roots blower can achieve the effect of forced aeration, and for the aeration of different areas, the aeration blower in the control unit is controlled by frequency conversion and time relays, so that the circulation of each area from the feed end to the discharge end can be realized and the aeration and oxygen supply function of the fermentation process can be performed according to the set time, which can achieve energy saving and consumption reduction, and greatly reduce production costs. Finally, multiple fans use the frequency converter inside the control unit, so that the aeration volume required for different aeration areas can be adjusted, further realizing the function of improving efficiency and reducing costs. At the same time, it can also avoid the equipment failure rate caused by the overall aeration and affect the production operation.

[0035] The working principle of this utility model:

[0036] The control unit is started, so that the Roots blower inside the control unit draws external gas into the main pipe 101 and the branch pipe 102, and then enters the installation head 201 and the aeration pipe 203 from the connecting port 202 after passing through the supporting pipe 103. During this period, the airflow pushes the baffle 205, and a gap is generated between the baffle 205 and the air outlet 204. The airflow is output from the air outlet 204 through the gap. During this period, the baffle 205 carries the connecting sleeve 209 on the outside of the screw 207 to move horizontally, and the spring 210 is squeezed and compressed, while the connecting rod 212 and the movable block 213 move in the connecting groove 216. When the main pipe 101 is shut down, the spring 210 releases its elastic potential energy to push the baffle 205 to reset and block the air outlet 204.

[0037] Secondly, by rotating the knob 217, the rotating sleeve 215 rotates the connecting slot 21, pushing the limit shaft 214 to drive the movable block 213 and the connecting rod 212 to rotate, so that the screw 207 rotates inside the bearing 206 and drives the connecting sleeve 209 to compress or stretch the spring 210, so that the force of the airflow pushing the baffle 205 to move changes, thereby affecting the output of the outlet 204.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
