Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for reaction vessels, specifically a material feeding device for reaction vessels. Background Technology

[0002] Bioreactors are devices used to realize biological processes such as cell culture, fermentation, and enzyme reactions. They are widely used in bioengineering and pharmaceutical industries. Existing bioreactors rely on manual or mechanical feeding methods. Biological reactions have strict environmental requirements, and existing feeding methods are difficult to meet production requirements. Feeding devices need to be disinfected and cleaned regularly, but existing feeding devices are difficult to clean and hinder industrial development.

[0003] For example, the patent document with announcement number CN222358452U describes an automatic feeding device. By setting up a sleeve and a feeding pipe that can rotate relative to each other, the material is conveyed through the feeding pipe, and the sleeve is driven to rotate by a drive mechanism. The sleeve drives the rotating sleeve block and the spray arm to rotate. During the rotation of the spray arm, it aligns and connects with multiple distributing channels on the distributing head in sequence. During this dynamic rotation, the material can follow the rotation of the spray arm and be dispersed and sprayed into the reaction tank, realizing the automatic and uniform addition of the material. This effectively solves the problem that the material is prone to clumping and agglomeration during feeding, which affects the mixing effect. However, after feeding, the automatic feeding device will leave raw material in the spray arm, resulting in low raw material utilization efficiency and inconvenience in cleaning the spray arm.

[0004] Based on this, a feeding device for reaction vessels is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-3 As shown, a feeding device for a reaction vessel includes a reaction vessel 101. A feeding seat 102 is provided at the upper end of the reaction vessel 101, and a discharge seat 103 is provided at the lower end of the reaction vessel 101. A support frame 104 is fixedly connected to the surface of the reaction vessel 101. The feeding seat 102 has a spreading mechanism inside the reaction vessel 101 for dispersing raw materials during feeding. The spreading mechanism includes a discharge seat 301, with a rotating block 302 fixedly connected to the lower end of the discharge seat 301. The discharge seat 301 is rotatably connected to a spray structure via the rotating block 302. The support frame 104 provides support for the reaction vessel 101. Reaction raw materials are fed into the reaction vessel 101 through the feeding seat 102, and the raw materials react inside the reaction vessel 101, providing conditions for the reaction vessel 101 to perform biological reactions such as cultivation, fermentation, and enzyme reactions.

[0028] In one embodiment, such as Figure 2As shown, the spray structure includes a rotating seat 303, a rotating block 302 rotatably connected to the rotating seat 303, a plurality of conveying pipes at the lower end of the discharge seat 301, and openings 304 adapted to the conveying pipes on the surface of the rotating seat 303. The side of the rotating seat 303 is connected to an output component for outputting raw materials. Raw materials are input into the discharge seat 301 through the conveying seat 102, and transferred to the rotating seat 303 through the conveying pipes at the lower end of the discharge seat 301. The rotating seat 303 continues to transmit raw materials through the openings 304 adapted to the conveying pipes, providing conditions for the feeding operation.

[0029] In one embodiment, such as Figure 3 and Figure 4 As shown, the output component includes a spray cylinder 305, and the rotating seat 303 connects to several spray cylinders 305. Each spray cylinder 305 is provided with a feed pipe 306 adapted to the opening 304. The surface of the spray cylinder 305 is provided with several spray nozzles 307. The spray cylinder 305 is slidably connected to a cleaning element for automatically cleaning raw materials. The inner wall of the rotating seat 303 is fixedly connected to a drive module that drives the rotating seat 303 to rotate. The raw materials inside the opening 304 are received through the feed pipe 306. The raw materials enter the spray cylinder 305. Pressure is provided by the sliding block 308. The raw materials enter the reaction tank 101 through the spray nozzles 307 to complete the feeding work. The raw materials are dispersed through the spray nozzles 307, so that the raw materials are more evenly dispersed during the feeding process, thereby accelerating the reaction efficiency.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the cleaning element includes a sliding block 308, which is slidably connected to the spray cylinder 305. One end of the sliding block 308 is fixedly connected to a piston plate, and the other end of the sliding block 308 is fixedly connected to a spring that drives the sliding block 308 to return to its original position. During the movement of the sliding block 308, the piston plate moves, and the piston plate pressurizes the raw material remaining inside the spray cylinder 305, so that the raw material is completely discharged, improving the utilization rate of raw material and reducing the difficulty of cleaning the spray cylinder 305.

After the conveying stops, the spring 309 resets and pushes the sliding block 308 to squeeze out the residual raw material.

[0032] In one embodiment, such as Figure 1 and Figure 2As shown, the drive module includes a second magnetic coupling 206. The second magnetic coupling 206 is fixedly connected inside the rotating seat 303. The second magnetic coupling 206 is rotatably connected to the discharge seat 301. The reaction tank 101 is provided with a magnetic drive device that provides power to the second magnetic coupling 206. The rotation of the second magnetic coupling 206 drives the rotating seat 303 to move, adjusts the position of the opening 304, stops the material conveying pipe, and stirs the raw materials inside the reaction tank 101 through the second magnetic coupling 206 to accelerate the reaction efficiency.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the magnetic drive device includes a fixed block 201. Several fixed rods 202 are fixedly connected to the upper end of the fixed rod 202. A fixed seat 203 is fixedly connected to the upper end of the fixed rod 202. A rotating motor 204 is installed in the middle of the fixed seat 203. The output end of the rotating motor 204 is fixedly connected to a first magnetic coupling 205. The first magnetic coupling 205 is rotatably connected to the fixed block 201. The rotating motor 204 drives the first magnetic coupling 205 to rotate, and the first magnetic coupling 205 drives the second magnetic coupling 206 to rotate, providing power for the rotation of the second magnetic coupling 206.

[0034] The above embodiment discloses a feeding device for a reaction vessel. The rotation of the second magnetic coupling 206 drives the rotating seat 303 to move, adjusting the position of the opening 304. The feeding pipe begins feeding material, which is input into the discharge seat 301 via the feeding seat 102. The material is then transferred to the rotating seat 303 via the feeding pipe at the lower end of the discharge seat 301. The rotating seat 303, through the opening 304, is adapted to the feeding pipe to continue transferring material, thus providing conditions for feeding. The feeding pipe 306 receives the material inside the opening 304, and the material enters the spray nozzle. Inside the spray cylinder 305, pressure is provided by the sliding block 308. The raw material enters the reaction tank 101 through the spray nozzle 307. The conveying pipe stops conveying material, and the spring 309 provides power to reset the sliding block 308. During the movement of the sliding block 308, the piston plate moves, and the piston plate pressurizes the raw material remaining inside the spray cylinder 305, so that the raw material is completely output. The rotating motor 204 drives the first magnetic coupling 205 to rotate, and the first magnetic coupling 205 drives the second magnetic coupling 206 to rotate, providing power for the rotation of the second magnetic coupling 206.
