Description

Technical Field

[0001] This utility model relates to the field of soy sauce production technology, specifically to a soy sauce filtration device. Background Technology

[0002] Soy sauce production requires multiple filtration processes to remove sediment and impurities produced during fermentation. Various soy sauce filtration devices are disclosed in the prior art, such as the soy sauce processing filter disclosed in patent 222900399U. This device adopts a box structure and achieves step-by-step filtration of soy sauce through a buffer chamber, a buffer stirring device, and a filter membrane. The buffer stirring device drives the impeller to rotate via a worm gear mechanism, agitating the liquid and slowing its flow rate while preventing impurities from accumulating on the filter membrane surface. This type of equipment, through a combination of mechanical buffering and stirring, extends the service life of the filter membrane and maintains filtration efficiency to a certain extent.

[0003] Existing filtration equipment has the following problems: the buffer stirring device has a complex structure, the worm gear transmission mechanism has high manufacturing cost and is prone to wear, and the maintenance frequency is high; the internal cleaning of the equipment is difficult, although it can prevent impurities from accumulating on the surface of the filter membrane, it cannot clean impurities in time, and after long-term use, the filtration load of the filter membrane is still large.

[0004] Based on the above situation, there is an urgent need for a soy sauce filtration device to solve the problem of the inability to remove impurities in a timely manner. Utility Model Content

[0005] The purpose of this utility model is to address the problems of existing filtration equipment, such as complex structure of buffer stirring device, high manufacturing cost and easy wear of worm gear transmission mechanism, high maintenance frequency, and difficulty in cleaning the inside of the equipment. Although it can prevent impurities from accumulating on the surface of the filter membrane, it cannot clean impurities in time. After long-term use, the filtration load of the filter membrane is still large. This invention solves the problem of not being able to clean impurities in time.

[0006] The technical solution of this utility model is as follows: A soy sauce filtering device, comprising: Sedimentation tank, used to settle soy sauce; The pre-filtration mechanism includes a centrifuge chamber and a drive unit for driving the centrifuge chamber. The inlet of the centrifuge chamber is connected to a liquid extraction pipe that extends into a sedimentation tank. Rotary joints are installed at both ends of the centrifuge chamber, and the centrifuge chamber is connected to an openable cover. The fine filtration assembly includes a delivery pipe connected to the outlet of the centrifuge chamber, and a filter element is installed on the delivery pipe; A liquid pump is installed on the liquid extraction pipe.

[0007] Existing filtration equipment suffers from complex buffer and stirring devices, high-cost and wear-prone worm gear transmission mechanisms, and frequent maintenance. Internal cleaning is difficult; while it prevents impurities from accumulating on the filter membrane surface, it cannot remove impurities promptly, resulting in a high filtration load on the membrane after prolonged use. In this solution, the sedimentation tank allows most solid impurities in the soy sauce to settle to the bottom. The pump then transports the clearer upper layer of soy sauce to the centrifuge chamber via a suction pipe. The drive unit rotates the centrifuge chamber and the soy sauce inside, causing residual solid impurities to be thrown against the chamber wall and deposited. Finally, the fine filtration component performs fine filtration. The sedimentation and centrifugation process removes more impurities, effectively reducing the filtration load on the filter element. Opening the cover allows for convenient and quick cleaning of deposited impurities in the centrifuge chamber, further reducing the filtration load and solving the problem of timely impurity removal.

[0008] Furthermore, this solution is not limited to the specific structure of the drive unit. One feasible solution is that the drive unit includes a driven gear disposed on the outer wall of the centrifuge chamber, and a motor is installed on the sedimentation tank, with a driving gear meshing with the driven gear mounted on the output shaft of the motor. When this solution is adopted, the driving gear is driven to rotate by the motor, thereby driving the driven gear and the centrifuge chamber to rotate synchronously. The gear transmission structure is compact, runs smoothly, has low noise, long service life, and the maintenance cycle can be several times that of worm gear transmission, effectively reducing the maintenance frequency and maintenance cost of the equipment.

[0009] Furthermore, to facilitate quick installation and disassembly of the centrifuge chamber, one feasible solution is that the rotary joint is connected to a quick-release connector. With this solution, the quick-release connector allows for convenient and quick installation or disassembly of the centrifuge chamber and the rotary joints at both ends of the centrifuge chamber.

[0010] Furthermore, to ensure the airtightness of the centrifuge chamber, one feasible solution is to thread the centrifuge chamber to the cover. This solution can effectively ensure the airtightness of the centrifuge chamber, and the cover can be installed or removed by rotating it.

[0011] Furthermore, to improve the pre-filtration effect, one feasible solution is to form convex ridges on the inner wall of the centrifuge chamber. When this solution is adopted, the convex ridges rotate with the centrifuge chamber and generate a strong shearing effect, which can effectively drive the soy sauce liquid to rotate, making it easier for impurities in the soy sauce liquid to be separated by centrifugation, thus effectively improving the pre-filtration effect.

[0012] Furthermore, to facilitate the cleaning of impurities deposited in the centrifuge chamber, one feasible solution is to make the cross-section of the protruding ridge semi-circular. With this solution, on the one hand, the curved surface structure can effectively drive the soy sauce liquid to rotate, ensuring the efficiency of centrifugal separation; on the other hand, compared with the common rectangular or trapezoidal cross-section protruding ridges, the smooth curved surface of the semi-circle effectively avoids cleaning dead corners. When the cover is opened for cleaning, the solid residue deposited between the protruding ridges and on the surface has less adhesion on the smooth curved surface and can be easily and thoroughly washed away by the water flow, thereby achieving efficient centrifugal separation and convenient cleaning.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: 1. The sedimentation tank allows most solid impurities in the soy sauce to settle to the bottom. The pump then pumps the clearer soy sauce liquid from the top to the centrifuge chamber through a pumping pipe. The drive unit rotates the centrifuge chamber and the soy sauce liquid inside, causing the remaining solid impurities in the soy sauce liquid to be thrown against the chamber wall and deposited. Finally, the soy sauce liquid undergoes fine filtration through the fine filtration assembly. The sedimentation and centrifugation process removes more impurities from the soy sauce liquid, effectively reducing the filtration load on the filter element. Opening the cover allows for convenient and quick cleaning of the impurities deposited in the centrifuge chamber, further reducing the filtration load on the filter element and solving the problem of not being able to clean impurities in a timely manner. Second, since the drive unit includes a driven gear set on the outer wall of the centrifuge chamber, and the sedimentation tank is equipped with a motor and the output shaft of the motor is equipped with a driving gear that meshes with the driven gear, the motor drives the driving gear to rotate, thereby driving the driven gear and the centrifuge chamber to rotate synchronously. The gear transmission structure is compact, runs smoothly, has low noise, long service life, and the maintenance cycle can be several times that of worm gear transmission, effectively reducing the maintenance frequency and maintenance cost of the equipment. Third, since the rotary joint is connected to a quick-release connector, the centrifuge chamber and the rotary joints at both ends of the centrifuge chamber can be installed or removed conveniently and quickly under the action of the quick-release connector.

[0016] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] Example: Please refer to Figures 1-5 A soy sauce filtering device, comprising: Sedimentation tank 1 is used to settle soy sauce. The upper part of sedimentation tank 1 is provided with liquid inlet pipe 11, and the lower part of sedimentation tank 1 is connected to slag discharge pipe 12 and slag discharge valve 13 is installed on slag discharge pipe 12. The pre-filtration mechanism 2 includes a centrifuge chamber 21 and a drive unit 22 for driving the centrifuge chamber 21. The inlet of the centrifuge chamber 21 is connected to a liquid extraction pipe 23 and the liquid extraction pipe 23 extends into the sedimentation tank 1. Rotary joints 24 are installed at both ends of the centrifuge chamber 21, and the centrifuge chamber 21 is connected to an openable cover 25. The fine filtration assembly 3 includes a delivery pipe 31 connected to the liquid outlet of the centrifuge chamber 21, and a filter element 32 is installed on the delivery pipe 31. The liquid pump 4 is installed on the liquid extraction pipe 23.

[0019] Existing filtration equipment suffers from complex buffer and stirring devices, high-cost and wear-prone worm gear transmission mechanisms, and frequent maintenance. Internal cleaning is difficult; while it prevents impurities from accumulating on the filter membrane surface, it cannot remove impurities promptly, resulting in a high filtration load on the membrane after prolonged use. In this solution, most solid impurities in the soy sauce settle to the bottom of the sedimentation tank 1. The pump 4 pumps the clearer upper layer of soy sauce liquid through the pump pipe 23 to the centrifuge chamber 21. The drive unit 22 rotates the centrifuge chamber 21 and the internal soy sauce liquid, causing residual solid impurities to be thrown against the chamber wall and deposited. Finally, fine filtration is performed through the fine filtration component 3. The sedimentation and centrifugation process removes more impurities, effectively reducing the filtration load on the filter element 32. Opening the cover 25 allows for convenient and quick cleaning of the deposited impurities in the centrifuge chamber 21, further reducing the filtration load on the filter element 32 and solving the problem of timely impurity removal.

[0020] Optionally, the filter element 32 can be a filter screen, filter cartridge, filter bag or filter membrane. All of the above structures can achieve fine filtration. In this embodiment, the filter element 32 is a diatomaceous earth filter cartridge and the filter cartridge is threadedly connected to the delivery pipe 31.

[0021] Reference Figure 4 This solution does not limit the specific structure of the drive unit 22. One feasible solution is that the drive unit 22 includes a driven gear 221 disposed on the outer wall of the centrifuge chamber 21, and a motor 222 is installed on the sedimentation tank 1. The output shaft of the motor 222 is equipped with a driving gear 223 that meshes with the driven gear 221. When this solution is adopted, the motor 222 drives the driving gear 223 to rotate, thereby driving the driven gear 221 and the centrifuge chamber 21 to rotate synchronously. The gear transmission structure is compact, runs smoothly, has low noise, long service life, and the maintenance cycle can be several times that of the worm gear transmission, effectively reducing the maintenance frequency and maintenance cost of the equipment.

[0022] Reference Figure 3 To facilitate quick installation and disassembly of the centrifuge chamber 21, one feasible solution is to connect the rotary joint 24 to the quick-release joint 26. With this solution, the quick-release joint 26 can be used to easily and quickly install or disassemble the centrifuge chamber 21 and the rotary joints 24 at both ends of the centrifuge chamber 21.

[0023] Preferably, a fixing seat 14 for fixing the quick-release connector 26 is formed on the sedimentation tank 1. When this solution is adopted, fixing the quick-release connector 26 by fixing the fixing seat 14 helps to reduce the vibration amplitude generated when the centrifuge chamber 21 rotates.

[0024] Reference Figure 2To ensure the airtightness of the centrifuge chamber 21, one feasible solution is to thread the centrifuge chamber 21 to the cover 25. This solution can effectively ensure the airtightness of the centrifuge chamber 21, and the cover 25 can be installed or removed by rotating it.

[0025] To improve the pre-filtration effect, one feasible solution is to form a convex ridge 211 on the inner wall of the centrifuge chamber 21. When this solution is adopted, the convex ridge 211 rotates with the centrifuge chamber 21 and generates a strong shearing effect, which can effectively drive the soy sauce liquid to rotate, making it easier for impurities in the soy sauce liquid to be separated by centrifugation, thus effectively improving the pre-filtration effect.

[0026] To facilitate the cleaning of impurities deposited in the centrifuge chamber 21, one feasible solution is to make the cross-section of the protrusion 211 semi-circular. With this solution, on the one hand, the curved surface structure can effectively drive the soy sauce liquid to rotate, ensuring the centrifugal separation efficiency; on the other hand, compared with the common rectangular or trapezoidal cross-section protrusions, the smooth curved surface of the semi-circle effectively avoids cleaning dead corners. When the cover 25 is opened for cleaning, the solid residue deposited between the protrusions 211 and on the inner wall of the centrifuge chamber 21 has less adhesion on the smooth curved surface and can be easily and thoroughly washed away by the water flow, thus achieving efficient centrifugal separation and convenient cleaning.

[0027] The working principle of this embodiment: The soy sauce concentrate first enters the sedimentation tank 1 through the inlet pipe. Under gravity, most solid impurities naturally settle to the bottom of the tank. Then, the pump 4 is activated to transport the relatively clear soy sauce liquid from the upper layer to the centrifuge chamber 21 through the suction pipe 23. Simultaneously, the motor 222 drives the centrifuge chamber 21 to rotate through the meshing of the drive gear 223 and the driven gear 221, causing the remaining solid impurities in the soy sauce liquid to be thrown against the chamber wall and deposited. The soy sauce liquid, after centrifugal pretreatment, enters the delivery pipe 31 through the rotary joint 24, and finally undergoes final fine filtration by the filter element 32. When cleaning is required, the entire centrifuge chamber 21 and the two rotary joints 24 at both ends of the centrifuge chamber 21 can be quickly disassembled using quick-release connectors. The threaded cover 25 can then be rotated and opened to rinse the inner wall of the centrifuge chamber 21. The entire process achieves multi-stage separation from sedimentation, centrifugal prefiltration to fine filtration, improving filtration efficiency and reducing maintenance costs.

[0028] To address the issue of timely impurity removal, this solution utilizes a sedimentation tank 1 to allow most solid impurities in the soy sauce to settle to the bottom. A pump 4 then pumps the clearer upper layer of soy sauce through a suction pipe 23 to a centrifuge chamber 21. A drive unit 22 rotates the centrifuge chamber 21 and the soy sauce inside, causing any remaining solid impurities to be thrown against the chamber wall and deposited. Finally, the soy sauce undergoes fine filtration through a fine filter assembly 3. The sedimentation and centrifugation process removes more impurities, effectively reducing the filtration load on the filter element 32. Opening the cover 25 allows for convenient and quick cleaning of the deposited impurities in the centrifuge chamber 21, further reducing the filtration load on the filter element 32 and resolving the problem of timely impurity removal.

[0029] To address the issue of high maintenance frequency, this solution incorporates a driven gear 221 mounted on the outer wall of the centrifuge chamber 21 within the drive unit 22. A motor 222 is installed on the sedimentation tank 1, and a drive gear 223 meshing with the driven gear 221 is mounted on the output shaft of the motor 222. The motor 222 drives the drive gear 223 to rotate, thereby causing the driven gear 221 and the centrifuge chamber 21 to rotate synchronously. This gear transmission structure is compact, operates smoothly, has low noise, and a long service life. The maintenance cycle is several times that of a worm gear transmission, effectively reducing the equipment's maintenance frequency and costs.

[0030] To facilitate quick installation and disassembly of the centrifuge chamber 21, in this design, since the rotary joint 24 is connected to the quick-release joint 26, the centrifuge chamber 21 and the rotary joints 24 at both ends of the centrifuge chamber 21 can be installed or disassembled conveniently and quickly under the action of the quick-release joint 26.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
