Description

Technical Field

[0001] This utility model belongs to the field of fermentation tank technology, and in particular relates to an oxygen supply pipeline for fermentation tanks. Background Technology

[0002] During the use of amino acid fermenters, oxygen needs to be supplied at different stages. Due to the relatively large volume of the fermenter, uneven oxygen supply from a single oxygen supply point will affect the fermentation efficiency and effect. At the same time, in order to avoid material backflow or contamination during the next production, a self-adjusting distributor needs to be installed at the gas outlet to automatically seal when oxygen is not supplied.

[0003] If multiple pipelines are laid out, each with its own distributor, there will be problems such as excessive quantity, volume occupation, and high cost. If a large number of distributors are laid out on a single pipeline, each distributor needs to bear the elasticity. If there are too many distributors, the oxygen supply pressure will be insufficient, resulting in backflow or repeated opening and closing, which will affect the quality and oxygen supply effect. Summary of the Invention

[0004] The purpose of this invention is to provide an oxygen supply pipeline for fermenters. By designing a novel oxygen supply pipeline, the position of the upper slider can be pneumatically controlled. Through the magnetic connection between the upper and lower sliders, the lower slider can be moved to any position of the conical opening. By supplying air to the lower slider in conjunction with the ventilation groove, air can be supplied to a single distribution mechanism, thus achieving single-point oxygen supply. Through the adjustable function of the upper and lower sliders, oxygen can be supplied to all distribution points sequentially, ensuring the supply pressure and stability of oxygen supply, and greatly improving the oxygen supply efficiency and effect.

[0029] Please see Figure 1-4 As shown, this utility model is an oxygen supply pipeline for a fermenter, including a tank body, a main body 1, an oxygen supply hose 2, an upper sliding member 3, and a lower sliding member 4;

[0030] The main body 1 is horizontally fixed to the tank body with both ends located outside the tank body;

[0031] The main body 1 has a partition 101 along the length direction, which is divided into an upper sliding cavity 102 and a lower sliding cavity 103. Both ends of the upper sliding cavity 102 are provided with sealing plates 104, and the two sealing plates 104 are respectively provided with an exhaust port 105 and an air supply connector 106.

[0033] The lower sliding member 4 includes a lower sliding block 401, which is slidably disposed in the lower sliding cavity 103. The bottom surface of the lower sliding block 401 is slidably sealed with the area of ​​the lower sliding cavity 103 with the conical opening 107. The lower sliding block 401 is provided with a venting groove 402. One end of the lower sliding block 401 is provided with a venting head 403 that communicates with the end of the venting groove 402. The other end of the venting groove 402 faces the direction of the conical opening 107. A lower magnet 404 is fixed on the side of the lower sliding block 401 near the partition 101.

[0034] The upper sliding member 3 includes an upper slider 301, which is slidably disposed in the upper sliding cavity 102. An upper magnet 302 that is magnetically connected to the lower magnet 404 is fixed on the side of the upper slider 301 near the partition 101. A seal is provided between the peripheral side of the upper slider 301 and the upper sliding cavity 102.

[0035] One end of the oxygen supply hose 2 is the input end and is connected to a branch 202 through a three-way control valve 201. The end of the branch 202 is connected to the gas supply connector 106. The other end of the oxygen supply hose 2 extends into the sliding chamber 103 and is connected to the gas inlet 403. The oxygen supply hose 2 between the main body 1 and the three-way control valve 201 forms a drop section 203 outside the tank.

[0036] Among them, such as Figure 2 As shown, the self-locking dispensing mechanism 5 includes a tube body 501, which is fixed to the side of the main tube body 1 and concentric with the conical opening 107. A slide rod 503 is slidably connected inside the tube body 501 through a support frame 502. One end of the slide rod 503 is fixed with a conical head 504 that cooperates with the conical opening 107. A spring 505 is fixed between the conical head 504 and the support frame 502.

[0037] Among them, such as Figure 4 As shown, the lower slider 401 has several universal balls 405 on its circumferential side, and the universal balls 405 roll along the inner wall of the lower sliding cavity 103.

[0038] Among them, such as Figure 2 As shown, both ends of the upper slider 301 are provided with flange portions 303, and the seal is provided on the circumferential side of the flange portion 303.

[0039] Among them, such as Figure 1 As shown, sealing sleeves 108 are fixed on both sides of the main pipe body 1. The sealing sleeves 108 are located at the connection point between the main pipe body 1 and the tank wall.

[0040] The sliding cavity 103 has open ends at both ends, and the inner wall of the end of the sliding cavity 103 near the drop section 203 is provided with rounded corners or chamfers.

[0041] Depending on the site environment and the size of the fermentation tank, an electric reel can be installed on the outside of the tank for collecting the coils of the falling section 203, or a storage box can be installed for temporary storage of the falling section 203.

[0042] A flow meter is installed at the end of the oxygen supply hose 2. The position of the upper slider 301 in the upper sliding cavity 102 is determined by measuring the flow rate. In conjunction with the PLC processor, the three-way control valve 201 and the flow meter are connected to the processor to achieve automatic control.

[0043] The working principle of this utility model is as follows: When oxygen needs to be supplied to the fermenter, oxygen is input through the end of the oxygen supply hose 2. First, the three-way control valve 201 is switched to supply air to the upper sliding cavity 102 through the branch 202. The internal pressure drives the upper slider 301 to move along the upper sliding cavity 102 until the upper slider 301 moves to the position of the first conical opening 107. During the displacement process, the upper slider 301 drives the lower slider 401 to move along through the upper magnet 302 and the lower magnet 404. The lower slider 401 moves to the conical opening 107 and the ventilation groove 402 is connected to the conical opening 107. The three-way control valve 201 is controlled to switch the oxygen to be delivered to the drop section 203, so that the oxygen is input into the conical opening 107 through the ventilation groove 402. The pressure pushes the conical head 504 down to achieve ventilation.

[0044] After the first conical port 107 is ventilated, the three-way control valve 201 is switched to the branch 202, and the upper slider 301 is moved a short distance to the second conical port 107. Oxygen supply continues in the same way until all the conical ports 107 have been continuously supplied with oxygen for a period of time. Then, the oxygen supply is stopped and the oxygen pump is reversed to draw gas from the upper sliding chamber 102 through the branch 202, which drives the upper slider 301 to reset in preparation for the next oxygen supply.
