Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, and particularly to a hop filtering device in a fermentation tank. Background Art

[0002] In the brewing industry of alcoholic beverages such as beer and fruit wine, the filtration treatment of hops in the fermentation tank is one of the key links affecting the quality of the final product. Hops can not only endow the liquor with unique aroma and bitterness during the fermentation process, but also play a role in anti-corrosion and clarification of the liquor. However, impurities such as residual hop debris in the fermentation broth will seriously affect the purity and taste of the liquor. Therefore, an efficient filtering device is needed to remove these impurities. Currently, there are some hop filtering devices in the fermentation tank on the market. Most of these existing devices adopt a simple single - stage filtration structure. Specifically, a filtering component is set at a specific position in the fermentation tank, and the fermentation broth flows into the filtration area from one side of the tank body and directly flows out from the other side after passing through the filtering component. Although this filtering method can intercept relatively large - sized particulate impurities such as hop debris to a certain extent, there are many obvious defects; In terms of filtration effect, due to single - stage filtration, the contact time and contact area between the fermentation broth and the filtering component are limited, resulting in some tiny hop impurities still flowing out with the fermentation broth, and full filtration cannot be achieved. The purity of the filtered liquid is difficult to meet the requirements of high - quality liquor brewing. Moreover, as the filtration process continues, the filter holes of the filtering component are extremely easy to be blocked by impurities. Once the filter holes are blocked, the filtration efficiency will drop sharply, and in severe cases, the filtration process cannot even proceed normally, and it is necessary to frequently stop the machine to clean or replace the filtering component. This not only increases the production cost but also seriously affects the production efficiency; In the filter residue treatment link, the treatment method of the existing devices for filter residue is relatively rough. The filter residue is usually simply piled up near the filtering component, lacking effective extrusion and dehydration measures. A large amount of liquid still remains in the filter residue, which not only causes waste of resources but also increases the volume of the filter residue, bringing inconvenience to the subsequent filter residue cleaning and disposal work. At the same time, the long - term accumulation of filter residue in the fermentation tank is likely to breed bacteria, pollute the fermentation environment, and thus affect the product quality of subsequent fermentation batches; In addition, during the filtration process of the existing devices, the fluidity of the liquid in the fermentation tank is poor, and concentration gradients and temperature gradients are likely to occur. The fermentation raw materials and fermentation strains cannot be fully mixed, nutrients cannot be evenly distributed, and metabolites cannot be diffused in time, resulting in an unstable growth and metabolism environment for the fermentation strains. This directly affects the fermentation efficiency, prolongs the fermentation cycle, and at the same time reduces the quality and yield of the fermentation products, making it difficult to meet the production requirements of modern large - scale, efficient, and high - quality liquor brewing. Summary of the Invention

A collection box fixedly installed on the outer wall of the filtering box is provided on one side of the rotating sealing plate. A first cylinder and a second cylinder are respectively installed at the upper and lower ends on the other side of the filtering box. The output end of the first cylinder is fixedly connected to a pressing plate, and the pressing plate is located above the filter plate. The output end of the second cylinder is fixedly connected to a movable plate, and the movable plate is located below the filter plate. The movable plate is located on one side of the pressing plate.

[0006] As a further preference of this technical solution, a groove is formed on the top of the movable plate, and a top rod adapted to the filter holes of the filter plate is slidably connected inside the groove. A first damping spring is provided at the bottom of the top rod.

[0007] As a further preference of this technical solution, a rectangular groove is formed on the filtering box, and a fixed rod is fixedly connected inside the rectangular groove. A clamping block is slidably connected to the top of the fixed rod. A clamping groove adapted to the clamping block is formed at the bottom of the rotating sealing plate. A second damping spring sleeved on the fixed rod is provided at the bottom of the clamping block.

[0008] As a further preference of this technical solution, a pushing block is provided on one side of the movable plate close to the collection box. A trapezoidal block is fixedly connected to one side of the bottom of the clamping block, and the positions of the trapezoidal block and the pushing block are adapted to each other.

[0009] As a further preference of this technical solution, a sleeve rod is fixedly connected to the outer wall of the rotating shaft, and the top of the sleeve rod is fixedly connected to the rotating disk. An upper gear and a lower gear are rotatably provided on the outer wall of the sleeve rod, and the upper gear is fixedly connected to the lower gear. A cross bar is fixedly connected to the side wall of the cylinder body, and a positioning gear meshing with the upper gear is provided on the cross bar.

[0010] As a further preference of the technical solution, fixing brackets are arranged on the side wall of the mounting bracket in a circumferential array. A moving rod is connected to the fixing brackets in a transverse sliding manner. Brush plates and mounting plates are respectively fixedly connected to both ends of the moving rod. A third damping spring sleeved on the moving rod is arranged between the brush plate and the fixing bracket.

[0011] As a further preference of the technical solution, a driving rod is rotatably connected to the fixing bracket. A cam is fixedly connected to the outer wall of the driving rod, and the side wall of the cam is in sliding fit with the mounting plate.

[0012] As a further preference of the technical solution, a driven gear meshing with the lower gear is fixedly connected to the top of the driving rod, and a row of stirring paddles is fixedly connected to the lower end of the driving rod.

[0013] Compared with the prior art, the following beneficial effects are achieved: After the pump body is started, the liquid can form a circulating flow among the cylinder body, the conveying pipe, the filtering box and the output pipe, and is filtered by the filter plate and then flows back to the cylinder body through the return pipe. This circulating filtering method can ensure that the liquid is in full contact with the filter plate, effectively improve the filtering effect and ensure the purity of the filtered liquid.

[0014] By using the second cylinder to drive the movable plate to move, the ejector rod passes through the filter holes in sequence. Under the action of the first damping spring, the hemispherical end of the ejector rod can be inserted into the filter holes to further dredge the filter holes. And subsequently, the ejector rod can sink into the groove according to the extrusion condition of the filter hole wall to continue dredging the subsequent filter holes, ensuring that the filter holes of the filter plate are unblocked and avoiding affecting the filtering efficiency due to the blockage of the filter holes; by using the first cylinder to drive the extrusion plate to move towards the side of the rotating sealing plate, the extrusion plate and the rotating sealing plate cooperate to extrude the filter residue, and the liquid in the filter residue can be fully extruded. On the one hand, the volume of the filter residue can be reduced, facilitating subsequent treatment; on the other hand, the liquid in the filter residue can be recycled, reducing resource waste and improving resource utilization rate; by the movement of the movable plate to drive the pushing block to push the trapezoidal block and the clamping block to move downward, the clamping action of the clamping block on the clamping groove of the rotating sealing plate is released, so that the rotating sealing plate opens as the extrusion plate moves, and the extrusion plate can push the filter residue to fall into the collection frame, realizing the automatic collection of the filter residue, without frequent manual intervention, improving work efficiency and reducing labor intensity.

[0015] The driving motor drives the rotating shaft to rotate, thereby causing the sleeve rod and the mounting bracket to drive the upper gear and the lower gear to revolve. At the same time, under the action of the positioning gear meshing with the upper gear, the upper gear and the lower gear rotate self - rotatively. The lower gear drives the driven gear, the driving rod, the cam and the stirring paddle to rotate self - rotatively. This combined way of revolution and self - rotation enables the stirring paddle to rotate around the rotating shaft while also rotating itself, greatly increasing the contact area between the stirring paddle and the liquid and the stirring method. It can make the liquid form a more complex and sufficient flow in the fermentation tank, effectively breaking the concentration gradient and temperature gradient in the liquid, fully mixing the fermentation raw materials and the fermentation strains, promoting the uniform distribution of nutrients and the timely diffusion of metabolites, thereby significantly improving the fermentation efficiency and shortening the fermentation cycle; sufficient stirring helps to maintain the uniformity of fermentation conditions such as the liquid temperature and pH value in the fermentation tank, avoiding the occurrence of local overheating or over - acidity, over - alkalinity, etc., providing a more stable and suitable growth and metabolism environment for the fermentation strains, and being beneficial to improving the quality and yield of fermentation products.

[0016] Under the elastic force of the third damping spring, the brush plate is closely attached to the inner wall of the cylinder body. When the rotating shaft rotates, the brush plate can comprehensively clean the inner cavity wall of the cylinder body. At the same time, the rotation of the cam cooperates with the elastic force of the third damping spring to drive the mounting plate, the moving rod and the brush plate to move horizontally back and forth, making the brush plate vibrate. This vibration can not only shake off the residues attached to the brush plate, avoiding the influence of the accumulation of residues on the cleaning effect of the brush plate itself, but also strengthen the cleaning force of the brush plate on the inner cavity wall of the cylinder body, more effectively removing the residues attached to the inner wall of the cylinder body and ensuring the cleanliness of the inner cavity wall of the cylinder body; timely cleaning of the residues on the inner cavity wall of the cylinder body can prevent the residues from breeding miscellaneous bacteria or deteriorating in the cylinder body, avoiding the pollution of these impurities to the subsequent fermentation process, thereby ensuring the quality and stability of each fermentation, improving the safety and quality of the product. Through this automatic cleaning mechanism, the frequency and workload of manual cleaning of the cylinder body are reduced, the labor cost and labor intensity are lowered. At the same time, keeping the cylinder body clean helps to extend the service life of the equipment and reduce the equipment maintenance and replacement costs caused by problems such as residue corrosion or blockage.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: In combination with Figures 1 - 8 as shown, the present invention provides a technical solution: a hop filtering device in a fermentation tank, the main components of which include a cylinder body 1, a liquid inlet pipe 11 is provided on the side wall of the cylinder body 1 for introducing the liquid to be filtered, a liquid discharge pipe 12 is provided at the bottom of the cylinder body 1 to discharge the filtered liquid after the filtering process is completed, a support base 13 is fixedly installed on the top of the cylinder body 1 to support other components, a rotating disk 2 is rotatably arranged at the upper end of the cylinder body 1, and a filtering component 3 is arranged on the rotating disk 2, and the filtering component 3 is responsible for the actual filtering work; The filtering component 3 includes a driving motor 31 fixedly installed on the top of the support base 13. The output end of the driving motor 31 is fixedly connected to a rotating shaft 32. The bottom end of the rotating shaft 32 is fixedly connected to a mounting frame 34. A filtering box 35 is arranged between the mounting frames 34. A delivery pipe 36 is arranged at the top of the filtering box 35. Liquid inlet holes 37 are formed on the surface of the other end of the delivery pipe 36 for introducing liquid. An output pipe 38 is arranged at the bottom of the filtering box 35. The other end of the output pipe 38 is provided with a pump body 39 mounted on the top of the rotating disk 2. The other end of the pump body 39 is provided with a reflux pipe 310 for refluxing the filtered liquid back into the cylinder body 1. A filter plate 311 is fixedly connected to the inner cavity of the filtering box 35. When filtering treatment is required, by starting the pump body 39, the liquid in the cylinder body 1 flows in turn through the delivery pipe 36, the filtering box 35, and the output pipe 38, and is filtered by the filter plate 311, and then refluxes back into the cylinder body 1 through the reflux pipe 310; A rotating sealing plate 312 is rotatably connected to one side of the filtering box 35, and the rotating sealing plate 312 is located above the filter plate 311. A collection box 313 fixedly installed on the outer wall of the filtering box 35 is arranged on one side of the rotating sealing plate 312 for collecting waste generated during the filtering process. A first cylinder 314 and a second cylinder 316 are respectively installed at the upper and lower ends of the other side of the filtering box 35. The output end of the first cylinder 314 is fixedly connected to a pressing plate 315, and the pressing plate 315 is located above the filter plate 311 for pressing the filter plate 311 to remove residues on the filter plate 311. The output end of the second cylinder 316 is fixedly connected to a movable plate 317, and the movable plate 317 is located below the filter plate 311. The movable plate 317 is located on one side of the pressing plate 315. A groove is formed at the top of the movable plate 317, and a push rod 318 adapted to the filter holes of the filter plate 311 is slidably connected in the groove. A first damping spring 319 is arranged at the bottom of the push rod 318 for controlling the movement of the push rod 318. A rectangular groove is formed on the filtering box 35, and a fixing rod 321 is fixedly connected in the rectangular groove. A clamping block 322 is slidably connected to the top of the fixing rod 321. A clamping groove adapted to the clamping block 322 is formed at the bottom of the rotating sealing plate 312. A second damping spring 323 sleeved on the fixing rod 321 is arranged at the bottom of the clamping block 322 for controlling the movement of the clamping block 322. A pushing block 320 is arranged on one side of the movable plate 317 close to the collection box 313. A trapezoidal block 324 is fixedly connected to one side of the bottom of the clamping block 322, and the trapezoidal block 324 and the pushing block 320 are adapted to each other's positions for pushing the clamping block 322, thereby realizing the rotation of the rotating sealing plate 312; In the process of treating the filter residue, the first cylinder 314 and the second cylinder 316 need to be started first. When the second cylinder 316 is activated, it drives the movable plate 317 to move toward the collecting frame 313. This action makes each push rod 318 pass through each filter hole in a row in turn. When the groove corresponds to the filter hole, the first damping spring 319 returns to its natural state and pushes the push rod 318 to move toward the filter hole. The hemispherical end of the push rod 318 will be inserted into the filter hole, thereby achieving the filter hole. One-step dredging, then, the hemispherical end of the push rod 318 will be squeezed by the hole wall of the filter hole, causing the push rod 318 to sink into the groove, preparing for the push rod 318 to dredge the subsequent filter hole, so that the push rod 318 can push the filter residue to the top of the filter plate 311, and at the same time, the first cylinder 314 will also drive the squeezing plate 315 to move in the direction of the rotating sealing plate 312, so that the squeezing plate 315 cooperates with the rotating sealing plate 312 to squeeze the filter residue, thereby effectively squeezing out the liquid in the filter residue; As the movable plate 317 moves toward the collecting frame 313, the movable plate 317 will also drive the pushing block 320 to move to the position of the trapezoidal block 324. The pushing block 320 will push the trapezoidal block 324 and the clamping block 322 to move downward and compress the second damping spring 323. This action makes the clamping block 322 no longer engage with the clamping groove of the rotating sealing plate 312. Therefore, when the squeezing plate 315 moves, it can push the rotating sealing plate 312 to rotate, so that the rotating sealing plate 312 opens. In this way, the squeezing plate 315 can push the filter residue to move and fall into the collecting frame 313. After that, the filter residue in the collecting frame 313 can be cleaned regularly. When the residue cleaning work is completed, the first cylinder 314 needs to be started again to make the extrusion plate 315 move in the opposite direction, and the rotating sealing plate 312 will rotate to a vertical state. Then, the second cylinder 316 is started to make the movable plate 317 move in the opposite direction, which will cause the push block 320 to separate from the trapezoidal block 324, and the card block 322 moves upward under the elastic force of the second damping spring 323, and re-engages in the card groove at the bottom of the rotating sealing plate 312. Through this series of actions, the rotating sealing plate 312 is fixed, ensuring the stable operation of the entire residue processing system.

[0021] In the embodiment of the present invention, during the filtering process, the pump body 39 needs to be started first, and the liquid in the cylinder body 1 will flow through the delivery pipe 36, the filter box 35, and the output pipe 38 in sequence. During the flow, the liquid will pass through the filter plate 311, thereby completing the filtering process. The filtered liquid will flow back to the cylinder body 1 through the return pipe 310 for recycling; When it is necessary to clean the filter residue generated during the filtering process, the first cylinder 314 and the second cylinder 316 can be started, and the second cylinder 316 will drive the movable plate 317 to move toward the collecting frame 313. During this process, each push rod 318 will pass through each filter hole in a row in turn. When the groove on the push rod 318 is aligned with the filter hole, the first damping spring 319 will return to its natural state and push the push rod 318 to move toward the filter hole, and the hemispherical end of the push rod 318 will be inserted into the filter hole. The filter hole is further unblocked. Subsequently, the hemispherical end of the push rod 318 is squeezed by the hole wall of the filter hole, causing the push rod 318 to sink into the groove to prepare for unblocking the subsequent filter holes. In this way, the push rod 318 can push the filter residue to the top of the filter plate 311. At the same time, the first cylinder 314 drives the squeezing plate 315 to move toward the direction of the rotating sealing plate 312. The squeezing plate 315 cooperates with the rotating sealing plate 312 to squeeze the filter residue, thereby squeezing out the liquid in the filter residue. As the movable plate 317 moves toward the collecting frame 313, the movable plate 317 will also drive the pushing block 320 to move to the position of the trapezoidal block 324, and the pushing block 320 will push the trapezoidal block 324 and the clamping block 322 to move downward and compress the second damping spring 323, so that the clamping block 322 no longer has a clamping effect on the clamping groove of the rotating sealing plate 312. Therefore, as the squeezing plate 315 moves, the rotating sealing plate 312 can rotate to the open state, so that the squeezing plate 315 can push the filter residue to move and fall into the collecting frame 313, and then the filter residue in the collecting frame 313 can be cleaned regularly; After the residue cleaning work is completed, first start the first cylinder 314 to make the extrusion plate 315 move in the opposite direction, and the rotating sealing plate 312 rotates to a vertical state. Then start the second cylinder 316 to make the movable plate 317 move in the opposite direction, which will cause the pushing block 320 to separate from the trapezoidal block 324, and the card block 322 moves upward under the elastic force of the second damping spring 323, and re-engages in the card groove at the bottom of the rotating sealing plate 312, thereby completing the fixation of the rotating sealing plate 312 and ensuring the sealing and stability of the system.

[0022] Embodiment 2: Combination Figure 3 , Figure 8As shown, on the basis of the first embodiment, a sleeve rod 33 is fixedly connected to the outer wall of the rotating shaft 32 of the present invention. The top of the sleeve rod 33 is fixedly connected to the rotating disk 2, ensuring the stability and reliability of the rotating disk 2. Two gears are rotatably arranged on the outer wall of the sleeve rod 33, namely the upper gear 325 and the lower gear 326. These two gears are fixedly connected together, ensuring that they can rotate synchronously. On the side wall of the cylinder 1, a cross bar 336 is fixedly connected. A positioning gear 337 meshing with the upper gear 325 is arranged on the cross bar 336, which can ensure the precise rotation of the rotating shaft 32. A plurality of fixing frames 327 are arranged in a circumferential array on the side wall of the mounting frame 34. A moving rod 328 is slidably connected horizontally on these fixing frames 327. Brush plates 329 and mounting plates 330 are fixedly connected to both ends of the moving rod 328 respectively. A third damping spring 331 sleeved on the moving rod 328 is arranged between the brush plate 329 and the fixing frame 327, which can ensure the stability and reliability of the brush plate 329 during movement. A driving rod 332 is rotatably connected to the fixing frame 327. A cam 334 is fixedly connected to the outer wall of the driving rod 332. The side wall of the cam 334 is in sliding fit with the mounting plate 330, which can ensure the precise rotation of the cam 334. A driven gear 333 meshing with the lower gear 326 is fixedly connected to the top of the driving rod 332, which can ensure the synchronous rotation of the driving rod 332 and the lower gear 326. A row of stirring paddles 335 is fixedly connected to the lower end of the driving rod 332, which can ensure the stability and reliability of the stirring paddles 335 during rotation.

[0023] In the embodiment of the present invention, when the driving motor 31 starts to work and drives the rotating shaft 32 to rotate, the rotating shaft 32 not only rotates itself, but also further drives the sleeve rod 33 and the mounting frame 34 connected thereto to rotate together. This linkage effect enables the sleeve rod 33 and the mounting frame 34 to work together, and then drives the upper gear 325 and the lower gear 326 to perform a revolution. Due to the precise meshing relationship between the positioning gear 337 and the upper gear 325, the positioning gear 337 enables the upper gear 325 and the lower gear 326 to not only perform a revolution, but also achieve a rotation. This rotation is further transmitted to the driven gear 333 meshing with the lower gear 326, causing it to also rotate. The rotation of the driven gear 333 finally drives the rotation of the driving rod 332, the cam 334, and the stirring paddles 335. The stirring paddles 335 can rotate while performing a revolution. This dual rotation enables the stirring paddles 335 to perform a more sufficient and uniform stirring process on the liquid, thus significantly improving the efficiency of the fermentation process. When it is necessary to clean the inner cavity wall of the cylinder body 1, the third damping spring 331 will exert its elastic force to push the brush plate 329 to closely fit the inner wall of the cylinder body 1. Subsequently, under the continuous rotation of the rotating shaft 32, the brush plate 329 can effectively clean the inner cavity wall of the cylinder body 1. At the same time, during the rotation of the cam 334, combined with the elastic force of the third damping spring 331, it can drive the mounting plate 330, the moving rod 328, and the brush plate 329 to move horizontally back and forth. This reciprocating movement causes the brush plate 329 to vibrate, which helps the residues attached to the brush plate 329 to fall off. The strengthening effect of the vibration further improves the cleaning strength between the brush plate 329 and the inner cavity wall of the cylinder body 1, ensuring the cleanliness of the inner cavity wall of the cylinder body 1. In this way, the pollution caused by residues can be effectively avoided, thus ensuring that the efficiency of the fermentation process will not be reduced due to the influence of residues.

[0024] Working principle of the hop filtration device in the fermentation tank: Step 1: By starting the pump body 39, the liquid in the cylinder body 1 flows in turn from the delivery pipe 36, the filter box 35, and the output pipe 38, and is filtered through the filter plate 311, and then flows back to the cylinder body 1 through the return pipe 310; Step 2: By starting the first cylinder 314 and the second cylinder 316, the second cylinder 316 drives the movable plate 317 to move towards the collection frame 313, so that each ejector rod 318 will pass through each filter hole in a row in turn. When the groove corresponds to the filter hole, the first damping spring 319 will return to its natural state and urge the ejector rod 318 to move towards the filter hole. The hemispherical end of the ejector rod 318 will be inserted into the filter hole, realizing further dredging of the filter hole. Then, the hemispherical end of the ejector rod 318 will be squeezed by the hole wall of the filter hole, causing the ejector rod 318 to sink into the groove, so that the ejector rod 318 can dredge the subsequent filter holes, so as to push the filter residue to the top of the filter plate 311. At the same time, the first cylinder 314 drives the pressing plate 315 to move towards the rotating sealing plate 312, so that the pressing plate 315 and the rotating sealing plate 312 can cooperate to squeeze the filter residue, so as to squeeze out the liquid in the filter residue; Step 3: At the same time, when the movable plate 317 moves towards the collection frame 313, the movable plate 317 can drive the pushing block 320 to move to the position of the trapezoidal block 324, so that the pushing block 320 pushes the trapezoidal block 324 and the clamping block 322 to move downward and compress the second damping spring 323, so that the clamping block 322 no longer forms a clamping effect on the card slot of the rotating sealing plate 312. This enables the rotating sealing plate 312 to be pushed to rotate as the pressing plate 315 moves, so that the rotating sealing plate 312 opens, enabling the pressing plate 315 to push the filter residue to move and fall into the collection frame 313, and then the filter residue in the collection frame 313 can be cleaned regularly; Step 4: After the filter residue cleaning is completed, start the first cylinder 314 to drive the extrusion plate 315 to move in the reverse direction, rotate the sealing plate 312 to the vertical state, and then start the second cylinder 316 to drive the movable plate 317 to move in the reverse direction. This causes the pushing block 320 to separate from the trapezoidal block 324, and the clamping block 322 moves upward under the elastic force of the second damping spring 323, so that the clamping block 322 is engaged in the card slot at the bottom of the rotating sealing plate 312, thus completing the fixation of the rotating sealing plate 312. Step 5: When the drive motor 31 drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the sleeve rod 33 and the mounting bracket 34 to rotate synchronously, so that the sleeve rod 33 and the mounting bracket 34 drive the upper gear 325 and the lower gear 326 to revolve. Since the positioning gear 337 is in meshing relationship with the upper gear 325, under the action of the positioning gear 337, the upper gear 325 and the lower gear 326 can rotate self - sufficiently. Thus, the lower gear 326 drives the engaged driven gear 333 to rotate self - sufficiently, and the driven gear 333 drives the drive rod 332, the cam 334, and the stirring paddle 335 to rotate self - sufficiently, so that the stirring paddle 335 can rotate self - sufficiently while revolving, enabling the stirring paddle 335 to fully stir the liquid and improving the fermentation efficiency.
