Description

[0002] Lysine is one of the essential amino acids for the human body. It can promote the development of the human body, enhance immunity and improve the central nervous system. As a feed additive, lysine can improve the animal's absorption of grain protein and calcium, promote animal growth, and improve the utilization of feed and protein resources.

[0003] During the lysine fermentation process, the primary seed tank is the process of amplifying the initial seeds. Its main function is to increase the seed density and improve the stability of the cells. In the actual production process, in order to balance the inoculation amount and production needs, one primary seed tank is usually transplanted with two secondary seed tanks. During the transplanting process, due to the small transplanting volume and low flow rate, the flow meter is prone to inaccuracy, which can easily lead to inaccurate transplanting volume and unstable secondary fermentation. After transplanting a secondary seed tank, the remaining lysine seed liquid in the primary seed tank will be pressurized and cooled. However, at this time, the volume of lysine seed liquid in the tank is low, and the interlayer of the fermentation tank still needs to be filled with water during pressure maintenance and cooling, resulting in a certain waste of resources. Therefore, it is necessary to improve the lysine seed tank to solve these problems.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0035] Embodiment 1:

[0036] See also Figure 1 The utility model provides a lysine seed tank, comprising a plurality of interconnected primary seed tanks 100, secondary seed tanks 200 and tertiary large tanks 300, wherein the volumes of the primary seed tanks 100, secondary seed tanks 200 and tertiary large tanks 300 gradually increase.

[0037] The first distribution plate is used to transport lysine seed liquid from the first-level seed tank 100 to the second-level seed tank 200 between multiple first-level seed tanks 100 and second-level seed tanks 200; the second distribution plate is used to transport lysine seed liquid from the second-level seed tank 200 to the third-level large tank 300 between multiple second-level seed tanks 200 and third-level large tanks 300.

[0038] Among them, one primary seed tank 100 can meet the amount of lysine seed liquid required by two secondary seed tanks 200, and one secondary seed tank 200 can meet the amount of lysine seed liquid required by one tertiary large tank 300.

[0039] See also Figure 2In order to achieve the above-mentioned distribution amount of lysine seed liquid, a second discharge pipe 7 is provided in the first-level seed tank 100, and the height of the second discharge pipe 7 in the first-level seed tank 100 is at most half of the inner cavity height of the first-level seed tank 100; a first discharge pipe 12 is provided at the bottom of the first-level seed tank 100. When the first-level seed tank 100 needs to transport lysine seed liquid to one of the second-level seed tanks 200, the lysine seed liquid is first discharged through the second discharge pipe 7, and when the top section of the second discharge pipe 7 is reached, the amount of lysine seed liquid required by one of the second-level seed tanks 200 is just met; when the lysine seed liquid is transported to another second-level seed tank 200, the lysine seed liquid is discharged through the first discharge pipe 12. The first discharge pipe 12 and the second discharge pipe 7 are both provided with control valves 9, and the first discharge pipe 12 and the second discharge pipe 7 are both connected to the transplanting pipe 10, and the transplanting pipe 10 connects multiple second-level seed tanks 200.

[0040] After the lysine seed liquid of the first-level seed tank 100 is transported to a second-level seed tank 200 through the second discharge pipe 7, there is no lysine seed liquid on the upper part of the first-level seed tank 100. In order to save cooling water for pressure maintenance, the outer wall of the first-level seed tank 100 can be provided with two cooling water chamber jackets, namely, an upper cooling water chamber jacket 4 and a lower cooling water chamber jacket 5. The upper cooling water chamber jacket 4 and the lower cooling water chamber jacket 5 are both provided with a water inlet 6 and a water outlet 8. Among them, the water inlet 6 and the water outlet 8 are located on opposite sides of the first-level seed tank 100, and the water inlet 6 is lower than the water outlet 8.

[0041] See also Figures 5 to 7 The second discharge pipe 7 is an adjustable pipe, including a fixed pipe 71, an adjusting pipe 72 and a transplanting pipe connecting pipe 73. The fixed pipe 71 and the transplanting pipe connecting pipe 73 are pipes of the same diameter. The adjusting pipe 72 is internally arranged between the fixed pipe 71 and the transplanting pipe connecting pipe 73. The adjusting pipe 72 is threadedly connected to the fixed pipe 71 and the transplanting pipe connecting pipe 73. Specifically, an external thread 721 may be provided on the adjusting pipe 72, and an internal thread adapted to the external thread 721 may be provided on the fixed pipe 71 and the transplanting pipe connecting pipe 73.

[0042] The top inner wall of the fixed tube 71 is provided with a sealing ring 711, and the sealing ring 711 is sealed and slidably connected with the adjusting tube 72; the bottom inner wall of the adjusting tube 72 is provided with an upper limit block 723 and a lower limit block 724, and the lower limit block 724 is located below the upper limit block 723, and the distance between the two is the moving distance of the adjusting tube 72; the inner wall of the transplanting pipeline connecting tube 73 is provided with a fixing ring 731, and the fixing ring 731 is located between the upper limit block 723 and the lower limit block 724. By rotating the adjusting tube 72, the upper limit block 723 and the lower limit block 724 can only move a limited distance under the limiting action of the fixing ring 731, so as to prevent the adjusting tube 72 from escaping from the fixed tube 71 and the transplanting pipeline connecting tube 73. In order to facilitate the rotation of the adjusting tube 72, a rotating handle 722 can be provided on the adjusting tube 72.

[0043] When the adjusting tube 72 moves downward to the bottom, the top of the adjusting tube 72 is flush with the top of the fixed tube 71; when the adjusting tube 72 moves upward to the top, the top of the adjusting tube 72 protrudes from the top of the fixed tube 71. At this time, the second discharge pipe 7 is located at the highest height in the first-level seed tank 100, which is half the height of the inner cavity of the first-level seed tank 100.

[0044] The second discharge pipe 7 is set as an adjustable pipe, and the height of the second discharge pipe 7 in the primary seed tank 100 can be adjusted according to the adapted secondary seed tank 200, so that half of the lysine seed liquid volume of the primary seed tank 100 can just meet the lysine seed liquid volume required by the secondary seed tank 200. For example, 5m 3 The first-level seed tank is 100, if it contains 4m 3 The amount of lysine seed liquid can be adjusted to a height of 2 m above the second discharge pipe 7 in the primary seed tank 100. 3 At the height, when the lysine seed liquid is transplanted, the lysine seed liquid is discharged through the second discharge pipe 7. When the height of the lysine seed liquid in the first-level seed tank 100 is flush with the top of the second discharge pipe 7, the discharge of the lysine seed liquid is stopped. At this time, the discharged lysine seed liquid just meets the needs of a second-level seed tank 200.

[0045] See also Figure 3 Two blocking blocks 14 are arranged in the cooling water chamber jacket 5, which are slightly lower than the height of the cooling water chamber jacket 5. A water inlet chamber 15 is formed between the two blocking blocks 14, and the water inlet 6 is connected to the water inlet chamber 15. When water is inletted, the cooling water source enters the water inlet chamber 15 from the water inlet 6, and then flows over the top of the water inlet chamber 15 into the cooling water chamber jacket 5; when the water supply is stopped, the cooling water in the cooling water chamber jacket 5 will not flow back due to the blocking of the two blocking blocks 14; when drainage is required, the cooling water can be discharged from the water outlet 8.

[0046] The structure of the upper cooling water chamber jacket 4 is the same as that of the cooling water chamber jacket 5, so it will not be described in detail.

[0047] See also Figure 4 Preferably, the water inlets 6 on the upper cooling water chamber jacket 4 and the lower cooling water chamber jacket 5 are arranged alternately. Such an arrangement avoids the problem that when the primary seed tank 100 is filled with the lysine seed solution required by the two secondary seed tanks 200, the water inlet chambers 15 in the upper cooling water chamber jacket 4 and the lower cooling water chamber jacket 5 are located at the same position in the vertical direction, resulting in poor cooling effects at the upper and lower water inlet chambers 15.

[0048] See also Figure 2 An air inlet pipe 11 is provided in the first-level seed tank 100, and the air inlet pipe 11 is connected to a distributor 16, and the distributor 16 is provided with a plurality of through holes.

[0049] The first-level seed tank 100 is provided with a stirring shaft 3, and the stirring shaft 3 is provided with a stirring paddle 13. The stirring shaft 3 is driven to rotate by the motor 1. When the stirring paddle 13 rotates, it does not contact the air inlet pipe 11, the distributor 16 and the second discharge pipe 7.

[0050] The primary seed tank 100 is also provided with a viewing window 2 .

[0051] Embodiment 2:

[0052] See also Figure 8 and Fig. 9 The utility model provides a lysine seed tank, which is different from the above embodiment in that: the distributor 16 includes three distribution rings arranged at equal intervals from top to bottom, namely a first distribution ring 161, a first distribution ring 162 and a third distribution ring 16, the first distribution ring 161, the first distribution ring 162 and the third distribution ring 16 are all connected to the air intake pipe 11, and the diameters of the first distribution ring 161, the first distribution ring 162 and the third distribution ring 16 are arranged from small to large, wherein the diameter of the first distribution ring 161 is larger than the distance from the air intake pipe 11 to the stirring shaft 3, and the diameter of the third distribution ring 16 is smaller than the distance from the air intake pipe 11 to the third distribution ring 16.

[0053] The stirring shaft 3 is provided with three groups of stirring paddles, namely, a first stirring paddle 131, a second stirring paddle 132 and a third stirring paddle 133. The three groups of stirring paddles and the three distribution rings are arranged alternately and not in contact. After the gas discharged from the distribution ring is stirred and cut by the stirring paddles, the large bubbles are cut into small bubbles, which are more easily dissolved in the lysine seed liquid, so that the bacteria can breathe more smoothly in the lysine seed liquid.

[0054] The utility model provides a lysine seed tank, wherein a first discharging pipe and a second discharging pipe are arranged in a first-level seed tank, and the two discharging pipes independently control the discharging and converge into a transplanting pipe to avoid material waste. The height of the second discharging pipe is adjusted to a suitable position by observing through a sight glass in advance. During the cultivation process of the lysine seed liquid in the seed tank, due to the high volume of the lysine seed liquid, two cooling water chamber jackets are arranged to form two cooling water circulation systems for temperature control. When the bacterial body is cultured to a suitable OD and needs to be transplanted, the discharging and transplanting are carried out from the second discharging pipe at this time, and the transplanting is carried out to the liquid level position on the top surface of the second discharging pipe. In this way, the transplanting volume can be controlled more accurately to avoid secondary fermentation abnormalities caused by inaccurate transplanting amount. After the first transplanting of the first-level seed tank is completed, the remaining lysine seed liquid needs to be pressure-maintained. Since the volume of the remaining lysine seed liquid is located at the lower position in the tank, it is only necessary to operate the cooling water circulation system of the cooling water chamber jacket and close the cooling water circulation system above, thereby solving the problem of resource waste caused by the need to fill the interlayer of the seed tank with water during cooling in the prior art. When the remaining lysine seed liquid needs to be discharged, it can be discharged through the first discharge pipe. The first discharge pipe and the second discharge pipe are combined into a transplanting pipe to transplant the seeds to the secondary seed tank. When the transplanting pipe is sterilized, only the pipe needs to be sterilized, which also helps to save production costs. The lysine seed tank of the utility model is more suitable for actual production needs.

[0055] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
