Description

Technical Field

[0001] This utility model relates to the field of yeast production technology, specifically a dust prevention device for yeast culture production. Background Technology

[0002] Yeast culture is a microecological product formed by yeast through full anaerobic fermentation on a specific culture medium under specific process conditions. The production of yeast culture is a systematic process based on the principle of microbial fermentation, integrating strain screening, environmental control, separation and purification. The core goal is to enable yeast to multiply in large quantities under controllable conditions and accumulate metabolites, ultimately forming a product that meets quality standards.

[0003] The following problems were found in the relevant technologies: During yeast cultivation and deep processing, processes such as raw material crushing, strain expansion, drying and granulation generate a large amount of ultrafine dust, of which particles with a diameter of less than 10 micrometers account for more than 60%. This type of dust is not only biologically active, but also easily adsorbs residual components of the culture medium to form sticky particles. This can lead to cross-contamination of strains in the production environment, affecting product purity, and poses a serious threat to the health of operators. Therefore, the generated dust should be dealt with in a timely manner. To address this, we have proposed a dust prevention device for yeast culture production.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the dust removal problem in yeast production mentioned above, this utility model provides a dust prevention device for yeast culture production, employing a rotating filter cartridge combined with a filter cartridge cleaning structure to ensure a safe environment for yeast production. The specific technical solution is as follows: A dust control device for yeast culture production includes a dust collection box. A filter cartridge is rotatably installed inside the dust collection box. A flow channel running longitudinally through the center of the filter cartridge is embedded in the inner cavity of the dust collection box. A dust collection hopper, which is attached to the inner wall of the filter cartridge, is fixed to the outer wall of the flow channel. A pipe port connected to the yeast culture production equipment is fixed to the outer wall of the dust collection box, and the inner end of the pipe port is connected to the flow channel through a connecting pipe. An air duct extending into the inner cavity and blowing towards the dust collection hopper is provided on the outer wall of the dust collection box. An exhaust fan communicating with the inner cavity of the dust collection box is provided on the outer wall of the dust collection box.

[0006] In the above technical solution, the air duct includes a blower fixed to the outer wall of the dust collector, the output end of the blower is connected to an air duct fixed to the outer wall of the dust collector, the outer wall of the air duct is fixed with a blowing branch pipe that penetrates the dust collector, and the blowing branch pipe is located on the inner and outer sides of the filter cartridge opposite to the dust collection hopper.

[0007] The dust collector has a partition embedded in its inner cavity, and a rotation drive component for driving the filter cartridge to rotate is provided on the side of the partition away from the filter cartridge.

[0008] The rotary drive component includes a drive gear rotatably disposed on the side wall of the partition, and a follower seat that penetrates the partition is fixed at the end of the filter cartridge, and a gear ring that meshes with the drive gear is sleeved on the outer wall of the follower seat.

[0009] The partition and the inner wall of the dust collector are both fixed with rotating brackets, and the two ends of the filter cartridge are respectively fixed with docking seats that are rotatably connected to the rotating brackets.

[0010] Ball bearings are evenly arranged circumferentially between the docking seat and the rotating bracket.

[0011] The dust collection hopper has a fan-shaped cross-section.

Detailed Implementation

[0016] 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.

[0017] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0018] A dust control device for yeast culture production includes a dust collection box 1. A filter cartridge 2 is rotatably mounted inside the dust collection box 1. The filter cartridge 2 rotates continuously inside the dust collection box 1, causing dust drawn into the dust collection box 1 to enter the filter cartridge 2 and fall evenly onto the circumferential filter holes of the filter cartridge 2. The filter cartridge 2 is a cylindrical body closed at both ends, with filter holes evenly distributed on its circumferential outer wall. A longitudinal flow channel 3 is embedded in the inner cavity of the dust collection box 1, penetrating the center of the filter cartridge 2. The flow channel 3 longitudinally penetrates the centers of both sides of the filter cartridge 2, preventing interference with the rotation of the filter cartridge 2. This allows the filter cartridge 2 to rotate circumferentially against the outer wall of the flow channel 3.

[0019] A dust collection hopper 4, which is attached to the inner wall of the filter cartridge 2, is fixed to the outer wall of the flow channel 3. A connecting groove is provided at the connection between the inner wall of the dust collection hopper 4 and the flow channel 3 to ensure that the sucked-in dust enters the interior of the dust collection hopper 4 through the flow channel 3. A pipe port 5, which is connected to the yeast culture production equipment, is fixed to the outer wall of the dust collector 1. The inner end of the pipe port 5 is connected to the flow channel 3 via a connecting pipe 6. A valve is installed on the pipe 5 to control the opening and closing of the pipe port 5. The pipe port 5 extends into the interior of the yeast culture production equipment through a connecting pipe.

[0020] After connecting the exhaust fan 8 to the power supply, dust in the production equipment is introduced into the flow channel 3 through the connecting pipe 6. The dust then enters the dust collection hopper 4 through the flow channel 3 and is filtered by the filter cartridge 2. The outer wall of the dust collector 1 is provided with an air duct 7 that extends into its inner cavity and blows towards the dust collection hopper 4. The exhaust fan 8 is connected to the inner cavity of the dust collector 1 through the outer wall of the dust collector 1. The air blown out by the air duct 7 is directed towards the filter holes in the dust collection hopper 4, preventing the filter holes from becoming clogged and ensuring airflow during the dust removal process, thus achieving a self-cleaning effect.

[0021] The air duct 7 includes a blower 10 fixed to the outer wall of the dust collector 1. The output end of the blower 10 is connected to an air duct 11 fixed to the outer wall of the dust collector 1. The outer wall of the air duct 11 is fixed with a blowing branch pipe 12 that penetrates the dust collector 1. The blowing branch pipe 12 is located on the inner and outer sides of the filter cartridge 2 opposite to the dust collection hopper 4.

[0022] The blower 10's air outlet is sealed and connected to the induced draft channel 11. Multiple blower branches 12 are fixedly installed on the outer wall of the induced draft channel 11. The other end of each blower branch 12 penetrates the outer wall of the dust collector 1 and adheres to the outer wall of the filter cartridge 2. The blower branch 12 blows air towards the dust collection hopper 4. This allows the air blown by the blower 10 to pass through the induced draft channel 11 and be blown by the blower branch 12 towards the outer wall of the filter cartridge 2, cleaning the filter pores of the filter cartridge 2 and allowing dust to enter the dust collection hopper 4 for collection, ensuring the airflow of the filter cartridge 2.

[0023] A partition 9 is embedded in the inner cavity of the dust collector 1. A rotary drive component for driving the filter cartridge 2 is provided on the side of the partition 9 away from the filter cartridge 2. The partition 9 divides the interior of the dust collector 1 into two spaces and protects the rotary drive component.

[0024] It is worth noting that the rotary drive component includes a drive gear 13 rotatably mounted on the side wall of the partition 9, and a follower seat 14 that penetrates the partition 9 fixed at the end of the filter cartridge 2. A gear ring 15 that meshes with the drive gear 13 is sleeved on the outer wall of the follower seat 14. The follower seat 14 rotates within the through hole of the partition 9, and the motor is fixed on the surface of the partition 9 by a frame. The drive gear 13 is fixedly sleeved on the outer wall of the motor output shaft through the central mounting hole, and the gear ring 15 is fixedly sleeved on the outer wall of the follower seat 14.

[0025] After the motor is connected to the power supply, the drive gear 13 rotates with the motor output shaft, which causes the gear ring 15 meshing with the drive gear 13 to drive the follower seat 14 to rotate, and the follower seat 14 drives the filter cartridge 2 to rotate continuously.

[0026] In addition, rotating brackets 16 are fixed to the opposite surfaces of the partition 9 and the inner wall of the dust collector 1, and docking seats 17 that are rotatably connected to the rotating brackets 16 are fixed to both ends of the filter cartridge 2.

[0027] In addition, ball bearings 18 are evenly arranged circumferentially between the docking seat 17 and the rotating bracket 16. The two annular rotating brackets 16 are respectively fixed to the inner walls of the dust collection box 1 on both sides. A sliding groove is opened circumferentially on the inner wall of the rotating bracket 16, and a movable groove is opened around the outer wall of the docking seat 17. Ball bearings 18 are movably embedded in the movable cavity formed by each movable groove and sliding groove. The stability of the filter cartridge 2 during rotation is ensured by the ball bearings 18 around the entire circle.

[0028] Furthermore, the cross-section of the dust collection hopper 4 is fan-shaped, and the curvature of the fan-shaped dust collection hopper 4 corresponds to that of the filter cartridge 2, ensuring that the dust collection hopper 4 fits snugly against the inner wall of the filter cartridge 2.
