Abstract
Description
Technical Field
[0001] This utility model relates to the field of incubator technology, and in particular to an air inlet structure for an incubator. Background Technology
[0002] In the process of microbial culture, cultivation tanks are typically used, and a culture medium is added to the tanks to provide the nutrients needed for the growth of the microorganisms. During the cultivation process in these tanks, oxygen is often introduced to prevent the microorganisms from dying due to lack of oxygen, thus ensuring their survival. However, existing cultivation tanks often use a single air intake pipe for oxygen supply. In practice, the oxygen distribution within the tank is not uniform, which can lead to microorganisms farther from the air intake pipe being unable to absorb oxygen in time and dying. This results in a high mortality rate, which is detrimental to the cultivation of the microorganisms. Utility Model Content
[0003] This invention proposes an air intake structure for a cultivation tank to solve the problem that in the actual oxygen supply of existing air intake structures, the oxygen distribution in the tank is not uniform enough, which leads to the death of bacteria that are far from the air intake pipe due to difficulty in timely oxygen absorption.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an air intake structure for a cultivation tank, comprising a tank body and an air intake pipe communicating with the interior of the tank body, wherein the interior of the tank body is further provided with an air distribution structure, and the air distribution structure is communicating with the air intake pipe;
[0005] The air distribution structure includes an air distribution plate and an air supply pipe connected to the air distribution plate. The air supply pipe is fitted with a sleeve that communicates with it, and the top end of the air supply pipe is connected to an air inlet pipe. The sleeve has an air inlet chamber inside, and the outer wall of the sleeve has evenly distributed first air outlet holes that communicate with the air inlet chamber. The air distribution plate has an air delivery chamber that communicates with the air supply pipe inside, and the air distribution plate has a second air outlet hole that communicates with the air delivery chamber.
[0006] Preferably, the top of the air distribution plate is also provided with a deformable air cushion, and the air cushion is provided with evenly distributed air outlets.
[0007] Preferably, the air distribution plate is provided with a connector for quick assembly and disassembly of the air cushion, and the connector includes multiple connector blocks installed at the bottom of the air cushion and a connector groove opened at the top of the air distribution plate. Multiple countersunk holes are opened on the outer circumference of the air distribution plate, and a pin is inserted into each countersunk hole. The interior of each of the multiple connector blocks is provided with a pin hole for the pin to be inserted.
[0008] Preferably, the inner wall of the tank is equipped with multiple guide rails, and the outer circumference of the air distribution plate and the air distribution pad are provided with slots that cooperate with the multiple guide rails.
[0009] Preferably, a sealing gasket is embedded on the inner wall of each slot to ensure the sealing between the guide rail and the slot.
[0010] Preferably, the top of the tank is equipped with a removable tank cover, and the tank cover is equipped with an exhaust valve, and the air inlet pipe is installed on the top of the tank cover.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0012] (1) By setting up the gas distribution structure, oxygen can be supplied to the middle and bottom of the tank at the same time, so that oxygen can be evenly distributed in the tank, allowing the bacteria in the tank to absorb oxygen in time.

[0023] 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.
[0024] This utility model provides, for example Figures 1-6 The air intake structure of the cultivation tank shown includes a tank body 1 and an air intake pipe 2 that communicates with the interior of the tank body 1. The interior of the tank body 1 is also provided with an air distribution structure, and the air distribution structure is connected to the air intake pipe 2. A detachable tank cover is installed on the top of the tank body 1, and an exhaust valve 3 is installed on the tank cover. The air intake pipe 2 is installed on the top of the tank cover.
[0025] The air distribution structure includes an air distribution plate 8 and an air supply pipe 4 connected to the air distribution plate 8. The air supply pipe 4 is covered with a sleeve 5 that communicates with it, and the top end of the air supply pipe 4 is connected to the air inlet pipe 2. The sleeve 5 has an air inlet chamber inside, and the outer wall of the sleeve 5 is provided with evenly distributed first air outlet holes 6. The first air outlet holes 6 communicate with the air inlet chamber. The air distribution plate 8 is provided with an air delivery chamber 14 that communicates with the air supply pipe 4, and the air distribution plate 8 is provided with a second air outlet hole 13 that communicates with the air delivery chamber 14.
[0026] Furthermore, in this embodiment, in order to improve the air distribution effect, such as Figures 2-6 As shown, the top of the air distribution plate 8 is also provided with a deformable air cushion 9, and the air cushion 9 is provided with evenly distributed air outlets 15.
[0027] As described above, during use, the air inlet pipe 2 can be connected to an external oxygen generator to provide oxygen. The oxygen is then delivered through the air inlet pipe 2 and the air delivery pipe 4 into the sleeve 5 and the air distribution plate 8. Subsequently, it is discharged into the culture medium inside the tank 1 through the first air outlet 6 and the second air outlet 13, providing oxygen to the bacteria. This achieves uniform oxygenation inside the tank 1, preventing bacteria in more distant areas from dying due to lack of oxygen, thus greatly improving the survival rate of the bacteria and facilitating their cultivation. Furthermore, when the air distribution plate 8 exhausts air into the tank 1 through the second air outlet 13, the air pressure causes the air distribution cushion 9 to be lifted and deformed. The shape creates a cavity between the air cushion 9 and the air distribution plate 8, and the air outlet 15 on the air cushion 9 opens accordingly. Then, the second air outlet 13 discharges gas through the air outlet 15 into the culture medium inside the tank 1 to provide oxygen for the bacteria. However, when the tank 1 discharges carbon dioxide through the exhaust valve 3, the pressure inside the tank 1 decreases, causing the air cushion 9 to press against the air distribution plate 8. At this time, the air outlet 15 closes to prevent the bacterial culture medium from flowing into the second air outlet 13. Similarly, an air distribution ring (not shown in the figure) can be fitted on the outside of the sleeve 5 to prevent the bacterial culture medium from flowing into the first air outlet 6, thereby ensuring the normal use of the air intake structure.
[0028] In another embodiment, such as Figures 2-6 As shown, the air distribution plate 8 is provided with a connector 12 for quick assembly and disassembly of the air cushion 9. The connector 12 includes multiple connector blocks 124 installed at the bottom of the air cushion 9 and a connector groove 123 opened at the top of the air distribution plate 8. Multiple countersunk holes 122 are opened on the outer circumference of the air distribution plate 8, and a pin rod 121 is inserted into each countersunk hole 122. The interior of the multiple connector blocks 124 is provided with a pin hole for the pin rod 121 to be inserted.
[0029] Furthermore, to facilitate the quick removal of the gas distribution plate 8 from inside the tank 1, such as... Figures 2-4 As shown, multiple guide rails 7 are installed on the inner wall of the tank 1, and slots 10 that cooperate with the multiple guide rails 7 are opened on the outer circumference of the air distribution plate 8 and the air distribution cushion 9.
[0030] When the air cushion 9 needs to be replaced, the canister cap on the top of the tank 1 can be opened, and the air supply pipe 4 can be pulled upwards, so that the air distribution plate 8 rises along the guide rail 7 through the slot 10 until the air distribution plate 8 is removed from the tank 1. Then, the pin rod 121 is pulled out from the countersunk hole 122, and the air cushion 9 is pulled upwards, so that the plug block 124 is pulled out from the plug groove 123. Then, the air cushion 9 is moved down along the air supply pipe 4 and removed. The new air cushion 9 is installed on the air distribution plate 8 along the air supply pipe 4. At this time, the plug block 124 is inserted into the plug groove 123. Then, the pin rod 121 is inserted into the countersunk hole 122 to insert and fix the plug block 124, thereby fixing the air cushion 9. Then, the air distribution plate 8 is inserted into the tank 1 through the slot 10 and the guide rail 7, thereby realizing the quick installation and removal of the air cushion 9, which is conducive to the replacement of the air cushion 9 and ensures the normal use of the air intake structure.
[0031] Meanwhile, in this embodiment, such as Figure 3 and Figure 4 As shown, a sealing gasket 11 is embedded on the inner wall of each slot 10. Based on this, the guide rail 7 and the slot 10 can be sealed, thereby ensuring the air distribution plate 8 and the inner wall of the tank 1, which helps to prevent leakage of the bacterial culture medium and facilitates the release of oxygen into the bacterial culture medium inside the tank 1, making it convenient for the bacteria to absorb oxygen.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
