Description

Technical Field

[0001] This utility model relates to the field of dragon fruit fermentation liquid production technology, specifically a pressing and filtering device for dragon fruit fermentation liquid production. Background Technology

[0002] Before extracting dragon fruit enzymes, fermentation is required. After fermentation, the pulp and fermentation liquid need to be separated for subsequent separation and purification.

[0003] According to Chinese Patent Application No. CN202121917074.3, a pressing and filtering device for producing dragon fruit fermentation liquid includes a fermentation filter tank and a second filter tank. The fermentation filter tank includes a fermentation tank body; a fermentation tank cover is provided on the top of the fermentation tank body; a telescopic rod is provided on the inner wall of the fermentation tank cover; a pressure plate is horizontally provided at the end of the telescopic rod; a shelf is provided inside the fermentation filter tank; the shelf is horizontally arranged; and a filter screen is provided on the shelf. This application obtains a high-purity fermentation liquid through multi-stage filtration, and adopts an integrated structure of fermentation and pressing, avoiding hygiene and safety hazards during material transfer, improving product quality, and shortening processing time. However, in the above-mentioned device, after primary pressing, pulp residue accumulates on the shelf. Due to the difficulty of cleaning, the accumulation of pulp residue may reduce pressing efficiency during operation, affecting the yield and quality of the fermentation liquid. Therefore, a pressing and filtering device for producing dragon fruit fermentation liquid is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pressing and filtering device for the production of dragon fruit fermentation liquid, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pressing and filtering device for the production of dragon fruit fermentation liquid, including a box body, on which a pressing and filtering mechanism is provided;

[0006] The pressing and filtering mechanism includes: an electric hydraulic cylinder, a shelf, a rotating rod, and a mounting plate. The electric hydraulic cylinder is connected to the top of the housing via a bracket. The electric hydraulic cylinder is self-locking, and its piston end extends into the housing. A pressure plate is connected to the piston end of the electric hydraulic cylinder. The shelf is slidably connected to the inner wall of the housing and has several drainage holes. Filter screens are connected to the drainage holes. The rotating rod is rotatably connected to the housing via bearings. An eccentric wheel is fixedly fitted onto the outer wall of the rotating rod, and the outer wall of the eccentric wheel is in contact with the bottom of the shelf. A worm gear is connected to the right end of the rotating rod. The mounting plate is connected to the right side of the housing. A worm gear is rotatably connected to the mounting plate via bearings. A handwheel is connected to the rear end of the worm gear. A discharge port is located on the left side of the housing. A sealing plate is hinged to the discharge port. By activating the electric hydraulic cylinder, the pressure plate is lowered, applying pressure to the dragon fruit fermentation material on the shelf. The extracted fermentation liquid seeps into the bottom of the housing through the filter screen in the leakage hole. After pressing, rotating the handwheel drives the worm gear to rotate. The worm gear meshes with the worm wheel, causing the rotating rod and eccentric wheel to rotate. This causes the eccentric wheel to lift the shelf, raising it to the level of the discharge port. By opening the sealing plate, the residue is discharged from the discharge port, facilitating residue cleaning, preventing accumulation that could affect subsequent pressing efficiency, and improving the extraction rate of the fermentation liquid.

[0007] Preferably, the outer wall of the shelf fits into the inner wall of the box to ensure that the shelf remains stable during the pressing process, while preventing the fermentation liquid from leaking out of the gaps and ensuring sufficient filtration. The worm gear meshes with the worm wheel.

[0008] Preferably, there are two eccentric wheels, which are arranged opposite each other on the outer wall of the rotating rod. The two opposing eccentric wheels rotate synchronously with the rotating rod, symmetrically lifting the shelf from both sides to ensure that the shelf is subjected to balanced force.

[0009] Preferably, a feed pipe is connected to the upper right side of the box, and the other end of the feed pipe is connected to an external fermentation tank. The fermented dragon fruit material is fed into the box through the feed pipe. A drain pipe is connected to the bottom of the box, and the other end of the drain pipe is connected to an external fine filtration tank. The fermented liquid after pressing and filtration is discharged from the bottom drain pipe to the subsequent processing equipment, forming a continuous production process.

[0010] Preferably, the housing is equipped with a pushing mechanism, which includes a second electric hydraulic cylinder. The second electric hydraulic cylinder is connected to the right side of the housing via a bracket. The second electric hydraulic cylinder is self-locking. The piston end of the second electric hydraulic cylinder extends into the interior of the housing. The piston end of the second electric hydraulic cylinder is connected to a push plate. After pressing, the second electric hydraulic cylinder is activated to push the push plate to the left, pushing the residue on the shelf towards the discharge port. This, combined with the opening of the sealing plate, achieves automatic slag discharge, replacing manual cleaning of residue, reducing downtime, lowering labor intensity, and preventing residue residue from affecting equipment efficiency.

[0011] Preferably, a storage groove is provided on the right inner wall of the box body, and the push plate is stored in the storage groove. During pressing, the push plate is stored in the storage groove on the right side of the box body, which does not occupy the pressing space and avoids interference with the material or the pressing plate. During slag discharge, the push plate extends out from the storage groove to ensure sufficient stroke to push away the residue.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This is a pressing and filtering device for producing dragon fruit fermentation liquid. By starting an electric hydraulic cylinder, the pressure plate is lowered, applying pressure to the dragon fruit fermentation material on the shelf. The extracted fermentation liquid seeps into the bottom of the chamber through the filter screen in the leakage hole. After pressing, the handwheel is turned to drive the worm gear to rotate. The worm gear meshes with the worm wheel, causing the rotating rod and eccentric wheel to rotate. This causes the eccentric wheel to lift the shelf, raising it to the level of the discharge port. By opening the sealing plate, the residue is discharged from the discharge port, facilitating residue cleaning, preventing accumulation that could affect subsequent pressing efficiency, and improving the extraction rate of the fermentation liquid.

[0014] 2. This pressing and filtering device for the production of dragon fruit fermentation liquid, after pressing, pushes the push plate to the left by starting the electric hydraulic cylinder, pushing the residue on the shelf to the discharge port. With the opening of the sealing plate, automatic slag discharge is achieved, replacing manual cleaning of residue, reducing downtime, reducing labor intensity, and avoiding residue residue from affecting equipment efficiency.

[0024] Please see Figure 1-4One embodiment of this utility model is: a pressing and filtering device for producing dragon fruit fermentation liquid, including a housing 1, on which a pressing and filtering mechanism 2 is provided; the pressing and filtering mechanism 2 includes: an electric hydraulic cylinder 21, a shelf 23, a rotating rod 25, and a mounting plate 28. The electric hydraulic cylinder 21 is connected to the top of the housing 1 via a bracket. The electric hydraulic cylinder 21 is self-locking. The piston end of the electric hydraulic cylinder 21 extends into the interior of the housing 1. The piston end of the electric hydraulic cylinder 21 is connected to a pressure plate 22. The shelf 23 is slidably connected to the housing. The inner wall of the body 1 and the outer wall of the shelf 23 are fitted together to ensure the stability of the shelf 23 during the pressing process and to prevent the fermentation liquid from leaking through the gaps, ensuring sufficient filtration. Several leakage holes 24 are provided on the shelf 23, and filter screens are connected inside the leakage holes 24. The rotating rod 25 is rotatably connected to the body 1 via bearings. An eccentric wheel 26 is fixedly fitted onto the outer wall of the rotating rod 25. The outer wall of the eccentric wheel 26 is fitted against the bottom of the shelf 23. There are two eccentric wheels 26, which are arranged opposite to each other on the rotating rod 25. On the outer wall of housing 5, two opposing eccentric wheels 26 rotate synchronously with the rotating rod 25, symmetrically lifting the shelf 23 from both sides to ensure balanced force on the shelf 23. A worm gear 27 is connected to the right end of the rotating rod 25. A mounting plate 28 is connected to the right side of housing 1. A worm 29 is rotatably connected to the mounting plate 28 via a bearing. The worm 29 meshes with the worm gear 27. A handwheel 210 is connected to the rear end of the worm 29. A discharge port is provided on the left side of housing 1. A sealing plate 211 is hinged to the discharge port. The pressure plate 22 is pushed by starting the electric hydraulic cylinder 21. The pressure is applied to the dragon fruit fermentation material on shelf 23 as it descends, and the extracted fermentation liquid seeps into the bottom of the box 1 through the filter screen in the leakage hole 24. After pressing, the worm gear 29 is rotated by turning the handwheel 210. The worm gear 29 meshes with the worm wheel 27, causing the rotating rod 25 and the eccentric wheel 26 to rotate. This causes the eccentric wheel 26 to lift the shelf 23, raising it to the level of the discharge port. By opening the sealing plate 211, the residue is discharged from the discharge port, which facilitates residue cleaning, avoids accumulation that affects subsequent pressing efficiency, and improves the extraction rate of fermentation liquid.

[0025] The upper right side of the box 1 is connected to the feed pipe 4, and the other end of the feed pipe 4 is connected to the external fermentation tank. The fermented dragon fruit material is fed into the box 1 through the feed pipe 4. The bottom of the box 1 is connected to the drain pipe 5, and the other end of the drain pipe 5 is connected to the external fine filter tank. The fermented liquid after pressing and filtration is discharged from the bottom drain pipe 5 to the subsequent processing equipment, forming a continuous production process.

[0026] Working principle: Fermented dragon fruit material is fed into the box 1 through the feed pipe 4. The electric hydraulic cylinder 21 is activated to push the pressure plate 22 down, applying pressure to the fermented dragon fruit material on the shelf 23. The extracted fermentation liquid seeps into the bottom of the box 1 through the filter screen in the leakage hole 24 and is discharged to the subsequent processing equipment through the bottom drain pipe 5. After pressing, the handwheel 210 is turned to drive the worm 29 to rotate. The worm 29 meshes with the worm wheel 27 to make the rotating rod 25 and the eccentric wheel 26 rotate, so that the eccentric wheel 26 lifts the shelf 23, making the shelf 23 rise to the same level as the discharge port. By opening the sealing plate 211, the residue is discharged from the discharge port, which is convenient for residue cleaning.

[0027] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, a pushing mechanism 3 is provided on the box 1. The pushing mechanism 3 includes: an electric hydraulic cylinder 31, which is connected to the right side of the box 1 via a bracket. The electric hydraulic cylinder 31 is self-locking, and its piston end extends into the interior of the box 1. A push plate 32 is connected to the piston end of the electric hydraulic cylinder 31. After pressing, the push plate 32 is moved to the left by activating the electric hydraulic cylinder 31, thus removing the material from the box. The residue on plate 23 is pushed towards the discharge port, and the automatic slag discharge is achieved in conjunction with the opening of sealing plate 211, which replaces manual cleaning of residue, reduces downtime, reduces labor intensity, and avoids residue residue affecting equipment efficiency; a storage groove is opened on the right inner wall of the box 1, and the push plate 32 is stored in the storage groove. During pressing, the push plate 32 is stored in the storage groove on the right side of the box 1, without occupying the pressing space and avoiding interference with the material or pressing plate 22; during slag discharge, the push plate 32 extends from the storage groove to ensure sufficient stroke to push away the residue.

[0028] Working principle: After pressing, the electric hydraulic cylinder 31 is activated to push the push plate 32 to the left, pushing the residue on the shelf 23 towards the discharge port, and the automatic slag discharge is achieved in conjunction with the opening of the sealing plate 211.
