Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, specifically a centrifugal separation dust removal device. Background Technology
[0002] In the production process of fermentation tank equipment, dust collectors play a crucial role as core environmental protection equipment to ensure the production environment and air quality. Fermentation production involves multiple stages such as microbial cultivation and fermentation product extraction, during which a large amount of dust and gas containing impurities such as mycelium and fermentation residues are generated. If not purified in time, it will not only threaten the health of operators, but may also cause safety accidents such as dust explosions in the workshop, while polluting the atmospheric environment. Centrifugal separation dust removal devices, with their efficient separation principle, separate dust and gas through centrifugal force and discharge the separated dust through sewage pipes, becoming a commonly used dust removal equipment in the production of fermentation tank equipment.
[0003] Because dust collectors generate vibration during operation, and the drain pipe is typically installed outside the dust collector, this vibration is transmitted to the drain pipe, causing it to rotate. Over time, the connection between the drain pipe and the dust collector is continuously subjected to vibration, causing the connecting parts to gradually loosen and the sealing performance to decline. In severe cases, the drain pipe may even detach. Once detached, it not only leads to the leakage of separated dust, polluting the working environment and affecting the health of operators, but also interrupts the normal operation of the dust collection system, increasing downtime for maintenance and repair costs. Currently, while some dust collectors on the market have improved the drain pipe connection structure, most of these improvements rely on conventional methods such as adding sealant and reinforcing bolts, failing to fundamentally solve the loosening problem caused by vibration and thus failing to meet the stability and reliability requirements of industrial production for dust collection equipment.

[0028] 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.
[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figure 1-3 As shown, this utility model is a centrifugal separation dust removal device, comprising:
[0031] Fermentation tank equipment 11;
[0032] A dust removal component, comprising a dust collector 21, which is installed at one end of the top of the fermentation tank equipment 11;
[0033] The fixing component includes a drain outlet 31, a support ring 32, a positioning groove 33, a support rod 34, a positioning frame 35, and a spring 36. The drain outlet 31 is located at the lower part of one end of the outer surface of the dust collector 21. The support ring 32 is fixed to the outer surface of the drain outlet 31. The positioning groove 33 is opened inside the support ring 32. The upper part of the positioning frame 35 is movably connected to the outer surface of the support rod 34. The spring 36 is wrapped around one end of the outer surface of the support rod 34. The positioning frame 35 is inserted into and connected to the inside of the positioning groove 33.
[0034] The coordinated design of spring 36 and positioning frame 35 provides a dual guarantee of dynamic buffering and rigid fixation for sewage pipe 25 and sewage outlet 31. The elastic force generated by spring 36 can absorb the vibration force of dust collector 21 during operation in real time, avoiding the vibration from directly acting on the connection part. When positioning frame 35 is inserted into positioning groove 33 under the action of spring 36, a mechanical limiting structure is formed. Spring 36 can dynamically adjust the pressure on positioning frame 35 by compression or extension, so that positioning frame 35 always maintains a stable clamp on sewage pipe 25, significantly reducing the probability of connection loosening or falling off due to vibration, and ensuring the long-term stable operation of dust removal system.
[0035] A rubber post 37 is bonded to one end of the outer surface of the positioning frame 35, and the rubber post 37 blocks one side of the outer surface of the support ring 32.
[0036] When the positioning frame 35 is inserted into the positioning groove 33, the rubber column 37 is squeezed and passes through the positioning groove 33, blocking the outside of the support ring 32.
[0037] The dust removal components also include an exhaust pipe 22, an exhaust pipe 23, an exhaust pipe 24, a sewage pipe 25, and a deodorization tower 26. The exhaust pipe 22 is located between the fermentation block equipment and the dust collector 21. The deodorization tower 26 is installed on the outer surface of the fermentation block equipment. The sewage pipe 25 is located at the lower part of one end of the outer surface of the dust collector 21, and its bottom is fixed to the top of the deodorization tower 26. The exhaust pipe 23 is fixed at the lower part of one end of the outer surface of the deodorization tower 26. The exhaust pipe 24 is fixed at one end of the outer surface of the exhaust pipe 23. A guide rod 41 is fixed at one end of the outer surface of the sewage pipe 25.
[0038] The guide ring 44 can move up and down outside the guide rod 41 to adjust the height of the positioning frame 35.
[0039] A guide ring 44 is movably connected to the outer surface of the guide rod 41, and the support rod 34 is fixed to one side of the outer surface of the guide ring 44.
[0040] A limiting disk 42 is fixed to the top of the guide rod 41, and a limiting ring 43 is provided on the lower part of the outer surface of the guide rod 41;
[0041] When the guide ring 44 moves up and down outside the guide rod 41, the limiting plate 42 and the limiting ring 43 can act as a block to limit the guide ring 44.
[0042] Working principle: When installing the drain pipe 25 and the drain outlet 31, the drain pipe 25 is first installed outside the drain outlet 31. At this time, the guide ring 44 is sleeved on the outside of the guide rod 41 and can move up and down along the guide rod 41. The installer moves the positioning frame 35 down along the guide rod 41 to the lower part. During this process, the positioning frame 35 applies pressure to the spring 36, compressing the spring 36 to generate elastic force. Under the action of the elastic force of the spring 36, the positioning frame 35 is inserted into the positioning groove 33. When the positioning frame 35 is inserted into the positioning groove 33, it will squeeze the rubber column 37, causing the rubber column 37 to deform and pass through the positioning groove 33, blocking the outside of the support ring 32. This blocking effect of the rubber column 37 achieves a tight fixation between the two.
[0043] The coordinated design of spring 36 and positioning frame 35 provides a dual guarantee of dynamic buffering and rigid fixation for sewage pipe 25 and sewage outlet 31. The elastic force generated by spring 36 can absorb the vibration force of dust collector 21 during operation in real time, avoiding the vibration from directly acting on the connection part. When positioning frame 35 is inserted into positioning groove 33 under the action of spring 36, a mechanical limiting structure is formed. Spring 36 can dynamically adjust the pressure on positioning frame 35 by compression or extension, so that positioning frame 35 always maintains a stable clamp on sewage pipe 25. Compared with the traditional rigid connection method, this structure can effectively resist the risk of loosening caused by high frequency vibration, significantly reduce the probability of connection loosening and falling off due to vibration, ensure the long-term stable operation of dust removal system, and avoid environmental pollution and production interruption caused by dust leakage.
[0044] During the fermentation of materials, the fermentation tank equipment 11 generates gases, impurities, and water vapor, which enter the centrifugal separator dust collector 21 through the fermentation tank exhaust pipe. The airflow cools inside the equipment, producing condensate, and impurities adhere to the conical sidewalls of the equipment, gradually sliding down to the bottom. The bottom of the equipment is connected to a dust collector drain pipe 25. The condensate and impurities pass through this pipe into a deodorization tower 26 for purification before being discharged. The gases are then discharged after being connected to high-altitude discharge pipes one and two through the dust collector exhaust pipe.
[0045] Please see Figure 1 , Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0046] The filter component includes an air outlet 51, a first filter ring 52, a second filter ring 53, a third filter ring 54, a filter screen 55, and upright plates 56. The air outlet 51 is located at the top of the dust collector 21. The first filter ring 52, the second filter ring 53, and the third filter ring 54 are located on the inner surface of the air outlet 51. Multiple upright plates 56 are fixed between the first filter ring 52, the second filter ring 53, and the third filter ring 54. The filter screen 55 is detachably connected to the inside of the first filter ring 52, the second filter ring 53, and the third filter ring 54 respectively.
[0047] The filter screens 55 inside filter ring 1 52, filter ring 2 53 and filter ring 3 54 have different mesh sizes, which can block finer impurities, allowing the blocked impurities to re-enter the dust collector 21.
[0048] A support plate 57 is fixed to the top of the filter ring 52. The support plate 57 is suspended above the inner surface of the air outlet 51. A rod 58 is fixed to the upper part of the inner surface of the air outlet 51. An insertion hole 59 is opened inside the support plate 57. The rod 58 is inserted and connected to the inside of the insertion hole 59. A fastening ring 591 is threaded to the outer surface of the rod 58.
[0049] Insert rod 58 is inserted into the inside of insertion hole 59, while fastening ring 591 is fixed to the outside of insert rod 58 by screw rotation, thereby fixing filter ring 1 52, filter ring 2 53 and filter ring 3 54.
[0050] Working principle: When fluid containing impurities enters the device, the mesh size of the filter screens 55 inside filter ring 1 52, filter ring 2 53 and filter ring 3 54 are different, which prevents it from being discharged directly. At the same time, the impurities that are blocked can re-enter the dust collector 21 for centralized treatment.
[0051] For fixing, during installation, align the insert rod 58 with the insertion hole 59 to initially position the filter ring. Then, screw the fastening ring 591 onto the outside of the insert rod 58 by rotating the thread. As the fastening ring 591 is tightened, it applies pressure to the filter ring 52, making it fit tightly and securely installed inside the air outlet 51. This ensures that during the fluid filtration process, it will not shift or loosen due to fluid impact or other external forces, thus guaranteeing the stability and efficiency of the entire filtration process.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
