Description

Technical Field

[0001] This application relates to the technical field of fermentation equipment, and in particular to a seed tank for producing fermentation products. Background Technology

[0002] Currently, in the field of biofermentation technology, seed tanks for fermentation are key equipment, playing a crucial role in the cultivation and fermentation process of microbial seeds. With the continuous development of biotechnology, the requirements for the efficiency, quality, and stability of the fermentation process are also increasing. The performance of the seed tank directly affects the growth and metabolism of microorganisms, thus impacting the overall yield and quality of fermentation production. Good seed culture can provide high-quality seeds for subsequent large-scale fermentation, helping to improve the yield and purity of fermentation products and promoting the development of multiple industries such as biopharmaceuticals and food fermentation.

[0003] In the past, in order to ensure the uniform mixing of materials and the fermentation effect in seed tanks used for production fermentation, the methods usually adopted included using simple stirring equipment: some seed tanks only have a small stirrer on the outside of the tank, and the simple stirring parts inside the tank are driven by external power to rotate in order to achieve the purpose of stirring materials; others use a stirring paddle fixed inside the tank, and rely on a motor to drive the stirring paddle to rotate to achieve the mixing of materials.

[0004] However, these existing technologies have obvious drawbacks: simple stirring equipment often has poor stirring effect and cannot fully mix the materials in the tank, resulting in inconsistent microbial growth environment and affecting fermentation efficiency and quality. Utility Model Content

[0005] In order to overcome the above problems, this application provides a seed tank for producing fermentation.

[0006] The technical solution for a seed tank used in fermentation production provided in this application is as follows: A seed production tank for fermentation includes a tank body with an inlet at the top and an outlet at the bottom. Multiple support legs are fixed at intervals at the bottom of the tank body. An agitator is installed inside the tank body, comprising a servo motor, a rotating rod, and stirring rods. The servo motor is fixed to the top of the tank body. The rotating rod is vertically positioned and fixedly connected to the servo motor. Multiple stirring rods are provided and fixedly positioned at intervals along the circumference of the rotating rod. The rotating rod has bidirectional threads and is connected to a defoaming device. The defoaming device includes a threaded sleeve, a connecting rod, and a first support rod. The threaded sleeve is threadedly connected to the rotating rod. The connecting rod is horizontally positioned and fixedly connected to the threaded sleeve. The first support rod is parallel to the connecting rod. Multiple spring connectors are spaced apart between the connecting rod and the first support rod. A telescopic rod is fixed to the side of the connecting rod away from the first support rod. Multiple defoaming needles are spaced apart on the end of the first support rod away from the connecting rod.

[0007] By adopting the above technical solution, the inlet on the tank is used for feeding, the outlet is used for discharging, and the support legs are used to support the tank. The servo motor of the stirring device drives the rotating rod to rotate, so that the stirring rod stirs the material in the tank. The bidirectional thread of the rotating rod enables the defoaming device to move on the rotating rod. The screw sleeve of the defoaming device is engaged with the screw thread of the rotating rod to achieve movement. The connecting rod connects the screw sleeve and the first support rod. The spring connector gives the first support rod a certain elasticity. The telescopic rod can play an auxiliary support and adjustment role. The defoaming device on the first support rod eliminates the foam in the tank.

[0008] Optionally, the end of the stirring rod away from the rotating rod is rotatably connected to a rotating shaft, the rotation axis of the rotating shaft is horizontal, and a rotating blade is fixedly connected to the rotating shaft.

[0009] By adopting the above technical solution, the tank is equipped with a stirring device to stir the material. The rotating rod is equipped with a bidirectional thread to allow the defoaming device to move up and down to defoam. The end of the stirring rod away from the rotating rod is rotatably connected to a rotating shaft in the direction of horizontal rotation, and the rotating blade is fixed on the rotating shaft, which allows the rotating blade to rotate with the rotating shaft during the stirring process, thereby enhancing the uniformity of the material stirring.

[0010] Optionally, a balance bar is horizontally fixed inside the tank, and a rotating rod passes through the balance bar and rotates relative to the balance bar.

[0011] By adopting the above technical solution, the balance bar can support and limit the rotation of the rotating rod, making the rotating rod more stable during rotation, reducing shaking and deviation, ensuring the normal operation of the stirring device and the defoaming device, and improving the fermentation effect.

[0012] Optionally, the inner wall of the tank is inclined at one end near the discharge port, and multiple inclined rods are fixed at intervals along the circumference of the rotating rod, with the inclined rods being perpendicular to the inclined surface of the inner wall of the tank.

[0013] By adopting the above technical solution, the fermentation material can flow more smoothly to the discharge port, reducing the residue of material in the tank. At the same time, the inclined rod can better stir the material near the discharge port, improving the uniformity of stirring.

[0014] Optionally, a sliding sleeve is fixed on the first support rod, and the sliding sleeve slides relative to the rotating rod while being sleeved on it. A second support rod is fixed on the sliding sleeve, and the second support rod is set parallel to the first support rod. Multiple defoaming needles are fixed at intervals on the side of the second support rod away from the first support rod.

[0015] By adopting the above technical solution, the sliding sleeve ring slides on the rotating rod, which enables the second support rod to move synchronously with the first support rod, increasing the distribution range of the defoaming needles and improving the defoaming efficiency.

[0016] Optionally, a slider is fixed to the end of the second support rod away from the rotating rod, and a slide rail is vertically fixed on the inner wall of the tank, and the slider slides in the slide rail.

[0017] By adopting the above technical solution, the second support rod becomes more stable during its up-and-down movement, ensuring the stability of the defoaming device. At the same time, it can guide the movement of the defoaming device, ensuring that the defoaming needle can accurately eliminate the foam.

[0018] Optionally, the top of the tank is provided with an air inlet, a screen is provided at the air inlet, and a protective cover is detachably connected to the air inlet.

[0019] By adopting the above technical solution, an air inlet is set at the top of the tank to realize gas exchange between the inside and outside of the tank, which meets the gas demand during the fermentation process; a net is set at the air inlet to prevent external debris from entering the tank and avoid affecting the fermentation process; a protective cover can be detached and connected to the air inlet, which can further protect against the entry of external impurities and facilitate the disassembly, cleaning or replacement of the protective cover.

[0020] Optionally, a heating and insulation layer is fixed to the inner wall of the tank, and a temperature detection device is fixed inside the tank.

[0021] By adopting the above technical solutions, setting up a heating and insulation layer inside the tank can maintain a stable temperature inside the tank, which is beneficial to the fermentation process; setting up a temperature detection device can conveniently monitor the temperature inside the tank and make timely adjustments to ensure a suitable fermentation environment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The stirring device ensures that the materials in the tank are thoroughly and evenly mixed, improving the microbial growth environment and enhancing fermentation efficiency and quality; 2. The installation of a defoaming device can fundamentally solve the problem of foam generation, avoiding the increased costs and introduction of impurities associated with the use of chemical defoamers; 3. The heating insulation layer and temperature detection device can control the internal temperature of the tank, providing a stable environment for microbial growth. Attached Figure Description

A temperature detection device 7 for measuring the temperature inside the tank is fixed on the inner wall of the tank body 1 and transmits data to the control system in real time.

[0029] refer to Figure 2 The tank body 1 is equipped with a defoaming device 4 and a stirring device 2. The stirring device 2 includes a servo motor 21, a rotating rod 22 and a stirring rod 23. The servo motor 21 is fixed to the top of the tank body 1. The rotating rod 22 is vertically set and fixedly connected to the servo motor 21. The rotating rod 22 rotates relative to the tank body 1, and the rotation axis of the rotating rod 22 is in the vertical direction. A balance rod 6 is horizontally fixed inside the tank body 1. A bearing is set on the balance rod 6. The rotating rod 22 passes through the bearing to facilitate the stability of the rotating rod 22. The rotating rod 22 is provided with a bidirectional thread.

[0030] Multiple stirring rods 23 are provided, and the multiple stirring rods 23 are fixed at intervals around the rotating rod 22. A groove is opened at the end of the stirring rod 23 away from the rotating rod 22. A rotating motor 3 is fixed in the groove. The rotating motor 3 is fixedly connected to a rotating shaft 31. The rotation axis of the rotating shaft 31 is horizontal. A rotating blade 32 is fixedly connected to the rotating shaft 31. The thickness of the rotating blade 32 gradually decreases from the end near the stirring rod 23 to the end away from the stirring rod 23. The rotating blade 32 is provided with a wave pattern, which can reduce the resistance when the rotating blade 32 rotates.

[0031] The inner wall of the tank 1 is inclined at one end near the discharge port 12 to facilitate material output. Multiple inclined rods 24 are fixed at intervals along the circumference of the rotating rod 22. The inclined rods 24 are perpendicular to or at a certain angle to the inclined surface of the inner wall of the tank 1, which is conducive to more thorough mixing of the material in the tank 1.

[0032] refer to Figure 2 The defoaming device 4 includes a screw sleeve 41, a connecting rod 42, a first support rod 43, a second support rod 44, and a sliding sleeve 431. The screw sleeve 41 is threadedly connected to the rotating rod 22. The connecting rod 42 is horizontally arranged and fixedly connected to the screw sleeve 41. The first support rod 43 is arranged parallel to the connecting rod 42. Multiple spring connectors 45 are spaced apart between the connecting rod 42 and the first support rod 43. Two telescopic rods 421 are fixed on the side of the connecting rod 42 away from the first support rod 43. The two telescopic rods 421 are symmetrically arranged relative to the rotating rod 22. The telescopic rods 421 are fixedly connected to the tank body 1.

[0033] The second support rod 44 is arranged parallel to the first support rod 43, and both the first support rod 43 and the second support rod 44 are fixedly connected to the sliding sleeve 431. The sliding sleeve 431 is fitted onto the rotating rod 22 and slides. Multiple defoaming needles 5 are fixed at intervals on the ends of the first support rod 43 and the second support rod 44 away from the connecting rod 42, which helps to eliminate bubbles generated in the tank 1.

[0034] The end of the second support rod 44 away from the rotating rod 22 is fixed with a slider 441. A roller is rotatably mounted on the slider 441. A slide rail 442 is vertically fixed on the inner wall of the tank 1. The roller slides in the slide rail 442. When the rotating rod 22 rotates, the stirring rod 23 stirs the material in the tank 1. The first support rod 43 and the second support rod 44 move up and down in a reciprocating motion under the action of the threaded connection between the screw sleeve 41 and the rotating rod 22. At this time, the defoaming needle 5 eliminates the air bubbles in the tank 1. The telescopic rod 421 and the spring connector 45 provide buffer for the first support rod 43 and the second support rod 44. The roller slides in the slide rail 442, which helps to increase the stability of the first support rod 43 and the second support rod 44 when they move.

[0035] The implementation principle of a seed tank for production fermentation according to an embodiment of this application is as follows: In the seed tank for production fermentation according to this embodiment, the servo motor 21 of the stirring device 2 drives the rotating rod 22 to rotate, so that the stirring rod 23 and the rotating blade 32 can fully stir the material, improve the mixing uniformity of the material, provide a good growth environment for microorganisms, and thus improve the fermentation efficiency and quality; the screw sleeve 41 of the defoaming device 4 moves up and down under the action of the bidirectional thread of the rotating rod 22, so that the defoaming needle 5 can treat the foam at different positions in the tank 1, avoiding the cost increase and impurity introduction problems caused by the use of chemical defoaming agents; at the same time, the heating and insulation layer 14 and the temperature detection device 7 ensure the stability of the temperature in the tank 1, which is conducive to the growth and fermentation of microorganisms. The setting of structures such as the support leg 15, the balance bar 6, and the inclined bar 24 improves the stability of the tank 1 and the comprehensiveness of material stirring.
