Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, in particular 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 of hops in fermentation tanks is one of the key links affecting the quality of the final product. During the fermentation process, hops not only impart a unique aroma and bitterness to the liquor, but also serve as a preservative and clarifier. However, impurities such as hop debris remaining in the fermentation liquid can seriously affect the purity and taste of the liquor. Therefore, an efficient filtration device is needed to remove these impurities. Currently, there are some hop filtration devices in fermentation tanks on the market. Most of these existing devices adopt a simple single-pass filtration structure. Specifically, a filter component is set at a specific position in the fermentation tank. The fermentation liquid flows into the filtration area from one side of the tank body and flows directly out of the other side after passing through the filter component. Although this filtration method can intercept larger particle impurities such as hop debris to a certain extent, it has many obvious defects.

[0003] In terms of filtration effect, due to the use of single-pass filtration, the contact time and contact area between the fermentation liquid and the filter component are limited, resulting in some tiny hop impurities still flowing out with the fermentation liquid, making it impossible to fully filter. The purity of the filtered liquid is difficult to meet the requirements of high-quality wine brewing. Moreover, as the filtration process continues, the filter pores of the filter component are easily clogged by impurities. Once the filter pores are clogged, the filtration efficiency will drop sharply. In severe cases, it may even cause the filtration process to be unable to proceed normally, requiring frequent shutdowns to clean or replace the filter components, which not only increases production costs but also seriously affects production efficiency.

[0004] In the filter residue treatment process, existing equipment uses a relatively rough method for handling filter residue. The filter residue is usually simply accumulated near the filter components, lacking effective extrusion and dehydration measures. A large amount of liquid still remains in the filter residue, which not only wastes resources but also increases the volume of the filter residue, causing inconvenience in subsequent filter residue cleaning and disposal. At the same time, the filter residue accumulates in the fermentation tank for a long time, which easily breeds bacteria and pollutes the fermentation environment, thus affecting the product quality of subsequent fermentation batches.

[0005] In addition, during the filtration process of the existing device, the liquid fluidity in the fermentation tank is poor, and concentration gradients and temperature gradients are prone to occur. The fermentation raw materials and fermentation bacteria cannot be fully mixed, the nutrients cannot be evenly distributed, and the metabolic products cannot diffuse in time, resulting in unstable growth and metabolic environment of the fermentation bacteria. This directly affects the fermentation efficiency, prolongs the fermentation cycle, and reduces the quality and output of the fermentation products, making it difficult to meet the needs of modern large-scale, efficient, and high-quality wine brewing production.

[0016] As a further preferred embodiment of the present 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.

[0017] Compared with the existing technology, it has the following beneficial effects:

[0018] After turning on the pump body, the liquid can circulate between the cylinder, delivery pipe, filter box, and output pipe, be filtered through the filter plate, and then return to the cylinder through the reflux pipe. This circulating filtration method can ensure that the liquid fully contacts the filter plate, effectively improve the filtration effect, and ensure the purity of the filtered liquid.

[0019] By utilizing the second cylinder to drive the movable plate to move, the push rod is made to pass through the filter holes in sequence. Through the action of the first damping spring, the hemispherical end of the push rod can be inserted into the filter hole to achieve further dredging of the filter hole, and the subsequent push rod can sink into the groove according to the extrusion of the filter hole wall to continue to dredge the subsequent filter holes, ensuring that the filter holes of the filter plate are unobstructed and avoiding the filtration efficiency being affected by the blockage of the filter holes; the first cylinder drives the extrusion plate to move toward the side of the rotating sealing plate, and the extrusion plate cooperates with the rotating sealing plate to extrude the filter residue, which can fully squeeze out the liquid in the filter residue. On the one hand, it can reduce the volume of the filter residue and facilitate subsequent processing; on the other hand, it can recycle the liquid in the filter residue, reduce resource waste and improve resource utilization; the movable plate moves and drives the pushing block to push the trapezoidal block and the card block downward, releases the card block from the card slot of the rotating sealing plate, and makes the rotating sealing plate open as the extrusion plate moves, and the extrusion plate can push the filter residue to fall into the collection frame, thereby realizing automatic collection of the filter residue without frequent manual intervention, improving work efficiency and reducing labor intensity.

[0020] The driving motor drives the rotating shaft to rotate, which in turn drives the sleeve rod and mounting frame to drive the upper gear and lower gear to revolve. At the same time, under the action of the meshing of the positioning gear and the upper gear, the upper gear and lower gear rotate, and the lower gear drives the driven gear, driving rod, cam and stirring paddle to rotate. This combination of revolution and rotation allows the stirring paddle to rotate while revolving around the rotating shaft, greatly increasing the contact area between the stirring paddle and the liquid and the stirring mode, so that the liquid can form a more complex and sufficient flow in the fermentation tank, effectively breaking the concentration gradient and temperature gradient in the liquid, so that the fermentation raw materials and the fermentation bacteria are fully mixed, promoting the uniform distribution of nutrients and the timely diffusion of metabolic products, thereby significantly improving fermentation efficiency and shortening the fermentation cycle. Sufficient stirring helps to maintain the uniformity of fermentation conditions such as temperature and pH of the liquid in the fermentation tank, avoids local overheating or over-acidity or over-alkalinity, provides a more stable and suitable growth and metabolic environment for the fermentation bacteria, and is conducive to improving the quality and yield of the fermentation product.

[0021] The brush plate fits tightly against the inner wall of the cylinder under the elastic force of the third damping spring. When the rotating shaft rotates, the brush plate can fully clean the inner wall of the cylinder. 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 back and forth laterally, so that the brush plate vibrates. This vibration can not only shake off the residue attached to the brush plate, and prevent the brush plate itself from being affected by the accumulation of residue and affecting the cleaning effect, but also strengthen the cleaning force of the brush plate and the inner wall of the cylinder, and more effectively remove the residue attached to the inner wall of the cylinder to ensure the cleanliness of the inner wall of the cylinder; timely cleaning of the residue on the inner wall of the cylinder can prevent the residue from breeding bacteria or deteriorating in the cylinder, and avoid these impurities from contaminating the subsequent fermentation process, thereby ensuring the quality and stability of each fermentation and improving the safety and quality of the product. Through this automatic cleaning mechanism, the frequency and workload of manual cleaning of the cylinder are reduced, and the labor cost and labor intensity are reduced. At the same time, keeping the cylinder clean helps to extend the service life of the equipment and reduce the equipment maintenance and replacement costs caused by problems such as corrosion or blockage by residues.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Combination 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 barrel 1, a liquid inlet pipe 11 is provided on the side wall of the barrel 1 for introducing the liquid to be filtered, and a liquid discharge pipe 12 is provided at the bottom of the barrel 1 for discharging the filtered liquid after the filtration process is completed. A support base 13 is fixedly installed on the top of the barrel 1 for supporting other components. A rotating disk 2 is rotatably provided at the upper end of the barrel 1, and a filter assembly 3 is provided on the rotating disk 2. The filter assembly 3 is responsible for the actual filtration work;

[0033] The filter assembly 3 includes a driving motor 31 fixedly mounted on the top of the support base 13, the output end of the driving motor 31 is fixedly connected to the rotating shaft 32, the bottom end of the rotating shaft 32 is fixedly connected to the mounting bracket 34, and a filter box 35 is arranged between the mounting brackets 34, and a delivery pipe 36 is arranged on the top of the filter box 35. A liquid inlet hole 37 is opened 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 filter box 35, and a pump body 39 mounted on the top of the rotating disk 2 is provided at the other end of the pump body 39. A return pipe 310 is provided at the other end of the pump body 39 for returning the filtered liquid to the cylinder 1. The inner cavity of the filter box 35 is fixedly connected to the filter plate 311. When filtering treatment is required, by turning on the pump body 39, the liquid in the cylinder 1 flows into the cylinder 1 from the delivery pipe 36, the filter box 35, and the output pipe 38 in turn, and is filtered through the filter plate 311, and then returns to the cylinder 1 through the return pipe 310;

[0034] One side of the filter box 35 is rotatably connected to a rotating sealing plate 312, and the rotating sealing plate 312 is located above the filter plate 311. One side of the rotating sealing plate 312 is provided with a collecting frame 313 fixedly installed on the outer wall of the filter box 35 for collecting waste generated during the filtration process. The upper and lower ends of the other side of the filter box 35 are respectively installed with a first cylinder 314 and a second cylinder 316. The output end of the first cylinder 314 is fixedly connected to a squeezing plate 315, and the squeezing plate 315 is located above the filter plate 311 for squeezing the filter plate 311 to remove the residue 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 squeezing plate 315. A groove is provided on the top of the movable plate 317, and the groove is provided with a groove. The cam 322 is pressed against the top of the filter housing 311 and the filter housing 312 is pressed against the top of the filter housing 311 to release the filter.

[0035] 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 causes each push rod 318 to 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 push 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. After one-step dredging, the hemispherical end of the push rod 318 will be squeezed by the 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. 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 will also drive the squeezing plate 315 to move toward 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;

[0036] When the second filter element 320 is in the closed position, the filter element 320 will be in the closed position, and the filter element 320 will be in the closed position, so the filter element 320 will be in the closed position.

[0037] When the residue cleaning work is completed, it is necessary to start the first cylinder 314 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, 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 into the card slot 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.

[0038] In the embodiment of the present invention, during the filtration process, the pump body 39 needs to be started first. The liquid in the cylinder 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 filtration process. The filtered liquid will flow back to the cylinder 1 through the return pipe 310 for recycling.

[0039] When it is necessary to clean the filter residue generated during the filtration process, the first cylinder 314 and the second cylinder 316 can be started. The second cylinder 316 will drive the movable plate 317 to move toward the collection 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. The hemispherical end of the push rod 318 will be inserted into the filter hole. The filter pores are further unblocked. Subsequently, the hemispherical end of the push rod 318 is squeezed by the wall of the filter pore, causing the push rod 318 to sink into the groove, preparing for unblocking the subsequent filter pores. 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 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.

[0040] When the filter bag 310 is in the closed position, the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, so ...

[0041] After the filter residue cleaning work is completed, the first cylinder 314 is first started to make the extrusion plate 315 move in the opposite direction, and the rotating sealing plate 312 rotates 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 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 into the card slot 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.

[0042] Example 2: Combination Figure 3 、 Figure 8As shown, on the basis of embodiment 1, a sleeve rod 33 is fixedly connected to the outer wall of the rotating shaft 32 of the present invention, and 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, and two gears are rotatably provided on the outer wall of the sleeve rod 33, namely the upper gear 325 and the lower gear 326, which are fixedly connected together to ensure that they can rotate synchronously, and a cross bar 336 is fixedly connected to the side wall of the cylinder 1, and a positioning gear 337 is provided on the cross bar 336 to engage with the upper gear 325, so as to ensure the precise rotation of the rotating shaft 32, and a plurality of fixing frames 327 are provided on the side wall of the mounting frame 34 in a circumferential array, and the fixing frames 327 are laterally slidably connected to the moving rods 328, and the two ends of the moving rods 328 The brush plate 329 and the mounting plate 330 are respectively fixedly connected, and a third damping spring 331 is provided between the brush plate 329 and the fixing frame 327, which can ensure the stability and reliability of the brush plate 329 when moving. The fixing frame 327 is rotatably connected to the driving rod 332, and the outer wall of the driving rod 332 is fixedly connected to the cam 334. The side wall of the cam 334 slides in fit with the mounting plate 330, which can ensure the precise rotation of the cam 334. The top of the driving rod 332 is fixedly connected to the driven gear 333 engaged with the lower gear 326, which can ensure the synchronous rotation of the driving rod 332 and the lower gear 326. The lower end of the driving rod 332 is fixedly connected to a row of stirring paddles 335, which can ensure the stability and reliability of the stirring paddles 335 when rotating.

[0043] In the embodiment of the present invention, when the driving motor 31 starts working 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, thereby driving the upper gear 325 and the lower gear 326 to perform an orbital motion. 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 revolve, but also to rotate on their own. This rotational motion is further transmitted to the driven gear 333 meshing with the lower gear 326, causing it to also rotate on its own. The rotational motion of the driven gear 333 ultimately drives the rotation of the driving rod 332, the cam 334 and the stirring paddle 335. The stirring paddle 335 can also rotate on its own while revolving on its own. This dual rotational motion enables the stirring paddle 335 to stir the liquid more fully and evenly, thereby significantly improving the efficiency of the fermentation process.

[0044] When the inner wall of the cylinder 1 needs to be cleaned, the third damping spring 331 will exert its elastic force to push the brush plate 329 to fit tightly against the inner wall of the cylinder 1. Then, under the continuous rotation of the rotating shaft 32, the brush plate 329 can effectively clean the inner wall of the cylinder 1. At the same time, during the rotation process, the cam 334, combined with the elastic force of the third damping spring 331, can drive the mounting plate 330, the moving rod 328 and the brush plate 329 to move back and forth laterally. This reciprocating movement causes the brush plate 329 to vibrate, which helps to fall off the residue attached to the brush plate 329. The enhanced effect of the vibration further enhances the cleaning force of the brush plate 329 and the inner wall of the cylinder 1, ensuring the cleanliness of the inner wall of the cylinder 1. In this way, the pollution caused by the residue can be effectively avoided, thereby ensuring that the efficiency of the fermentation process will not be reduced due to the influence of the residue.

[0045] Working principle of hop filtration device in fermentation tank:

[0046] Step 1: By turning on the pump 39, the liquid in the cylinder 1 flows into the delivery pipe 36, the filter box 35, and the output pipe 38 in sequence, and is filtered by the filter plate 311, and then flows back into the cylinder 1 through the return pipe 310;

[0047] When the filter is in the closed position, the filter press 314 closes, and the filter press 314 closes, so that the filter press 314 closes, and the filter press 314 closes.

[0048] When the filter bag 310 is in the closed position, the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, so the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, so the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, so the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag 310 will be in the closed position, and the filter bag

[0049] Step 4: After the filter residue is cleaned, the first cylinder 314 is turned on to drive the extrusion plate 315 to move in the opposite direction, and the rotating sealing plate 312 is rotated to a vertical state. Then, the second cylinder 316 is turned on to drive the movable plate 317 to move in the opposite direction, so that the pushing block 320 is separated from the trapezoidal block 324. The clamping block 322 moves upward under the elastic force of the second damping spring 323, so that the clamping block 322 is engaged with the clamping groove at the bottom of the rotating sealing plate 312, thereby completing the fixing of the rotating sealing plate 312.

[0050] Step 5. When the driving motor 31 drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the sleeve rod 33 and the mounting frame 34 to rotate synchronously, so that the sleeve rod 33 and the mounting frame 34 drive the upper gear 325 and the lower gear 326 to revolve. Since the positioning gear 337 is in a meshing relationship with the upper gear 325, the upper gear 325 and the lower gear 326 can rotate on their own under the action of the positioning gear 337, so that the lower gear 326 drives the meshing driven gear 333 to rotate on its own, so that the driven gear 333 drives the driving rod 332, the cam 334, and the stirring paddle 335 to rotate on their own, so that the stirring paddle 335 can also rotate on its own while revolving, so that the stirring paddle 335 can fully stir the liquid, thereby improving the fermentation efficiency.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
