Description

Technical Field

[0001] This utility model relates to the field of vinegar production, and in particular to a filtration device for vinegar production. Background Technology

[0002] As a traditional fermented food, vinegar produces solid impurities during its production process due to raw material residues and microbial metabolites. These impurities not only affect the clarity and sensory quality of vinegar, but may also lead to sedimentation and spoilage during subsequent storage. Therefore, filtration is a key post-processing step in vinegar production.

[0003] In existing technologies, such devices are mostly single filter tanks or filter barrels, with only filter media such as filter plates, filter cloths, and filter membranes inside, used to filter solid impurities in vinegar. However, in actual use, during filtration, when the amount of vinegar discharged from the outlet pipe decreases, the filter plates and filter holes are easily clogged by impurities, requiring manual shutdown for disassembly and cleaning. In this process, not only is production interrupted and inefficient, but the filter holes are also prone to clogging again during continuous filtration, requiring frequent operation and further increasing the frequency of manual cleaning, making it difficult to adapt to the needs of continuous production.

[0004] Therefore, it is necessary to propose a filtration device for vinegar production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for vinegar production, in order to solve the problems of easy clogging of filter holes and the need for frequent shutdowns for cleaning in existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for vinegar production, comprising a filter tank, wherein a discharge pipe is fixedly connected to the side wall of the filter tank, and a cleaning mechanism is provided inside the filter tank;

[0007] The cleaning mechanism includes a bracket fixedly connected to the inner wall of the filter tank. A connecting sleeve is fixedly connected to the end of the bracket away from the filter tank. A gear is rotatably connected inside the connecting sleeve. A rotating brush is fixedly connected to the lower surface of the gear. A rack is slidably connected inside the connecting sleeve. The gear meshes with the rack. A pressure plate is fixedly connected to the end of the rack away from the connecting sleeve. A first groove is formed on the inner wall of the discharge pipe. The pressure plate is slidably connected in the first groove. A push column is fixedly connected to the side of the pressure plate away from the rack. A fixing plate is fixedly connected to the inner wall of the discharge pipe. A return spring is fixedly connected between the opposite surfaces of the fixing plate and the pressure plate. The push column is slidably connected to the inner side of the fixing plate.

[0008] Preferably, the upper surface of the filter tank is detachably connected with an end cap.

[0009] Preferably, a feed pipe is fixedly connected to the side wall of the filter tank away from the discharge pipe.

[0010] Preferably, a first drain valve is fixedly connected to the side of the filter tank near the discharge pipe.

[0011] Preferably, a second drain valve is fixedly connected to the lower surface of the filter tank.

[0012] Preferably, a filter cylinder is fixedly connected to the inner wall of the filter tank, the upper surface of the filter cylinder is inclined, the inclined surface of the filter cylinder faces the side opposite to the feed pipe, the inclined surface of the filter cylinder is in contact with the inner wall of the filter tank, and the second drain valve is connected to the filter cylinder.

[0013] Preferably, the filter cartridge has a first through hole on one side wall near the discharge pipe, the rack passes through the first through hole, the brush surface of the rotating brush is in contact with the inner wall of the filter cartridge, and the rotating brush is aligned with the axis of the filter cartridge.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, through the cleaning mechanism, as the filtration time increases, the filter holes on the inner wall of the filter cylinder are gradually blocked by impurities. When the impact force is less than the elastic force of the return spring, the gear drives the rotating brush to rotate synchronously under the action of the return spring. During the rotation, the brush bristles brush the filter holes on the inner wall of the filter cylinder, removing the impurities blocked in the filter holes. As the filter holes are gradually cleared, the flow rate of vinegar in the discharge pipe increases, and the impact force on the pressure plate is again greater than the elastic force of the return spring. The return spring is contracted and stored energy, and the equipment returns to the normal filtration state. Thus, in this process, a blockage cleaning can be completed without stopping the machine, realizing continuous filtration and reducing the frequency of manual cleaning.

[0016] 2. The vinegar is made to flow along the inclined surface of the filter cylinder and enter the inside of the filter cylinder. Under pressure, the vinegar passes through the filter holes in the filter cylinder wall. The solid impurities are trapped by the filter holes and remain inside the filter cylinder or adhere to the inner wall of the filter cylinder, thus completing the solid-liquid separation.

[0024] This utility model provides, for example Figures 1-6 The filtration device shown is designed for vinegar production and aims to solve the problems of easy clogging of filter holes and the need for frequent shutdowns for cleaning in the prior art.

[0025] The filter tank 1 serves as the main body of the equipment, providing a closed filtration space to prevent vinegar from coming into contact with the outside world and becoming contaminated during the filtration process. At the same time, it provides stable support for all internal components such as the filter cartridge 7 and the cleaning mechanism 8, ensuring that each structure does not shift during operation.

[0026] The end cap 3 is detachably connected to the upper surface of the filter tank 1. It is kept closed during daily use to maintain the sealing of the tank. When it is necessary to repair the filter cartridge 7 or replace the rotating brush 84, the end cap 3 can be directly removed without disassembling the entire equipment, thus reducing the difficulty of maintenance.

[0027] The feed pipe 4 is fixed on the side wall of the filter tank 1 away from the discharge pipe 2, and is responsible for conveying the vinegar to be filtered into the tank. Its position corresponds to the inclined surface of the filter cylinder 7.

[0028] The discharge pipe 2 is fixed to the side wall of the filter tank 1 and is used to discharge the filtered clean vinegar. The first groove opened on its inner wall provides a sliding track for the pressure plate 86. When the discharge volume changes, the cleaning mechanism 8 can be triggered by the sliding of the pressure plate 86. It is the key channel for the equipment to achieve "cleaning when blocked".

[0029] The filter cartridge 7 is fixed to the inner wall of the filter tank 1 and is the core medium for vinegar filtration. It traps solid impurities in the vinegar through the filter holes in the cartridge wall, ensuring that the vinegar discharged from the outlet pipe 2 is clean. The upper surface is designed as an inclined surface, which can reduce the impact force when the vinegar flows in and guide impurities to gather towards the drain outlet, reducing the adhesion of impurities to the inner wall of the filter cartridge 7. The inclined surface of the filter cartridge 7 fits in close to the inner wall of the filter tank 1, and a first through hole is opened on the side wall near the outlet pipe 2 for the rack 85 to pass through, ensuring that the cleaning mechanism 8 and the filter cartridge 7 are linked to achieve precise cleaning.

[0030] The first drain valve 5 is fixed on the side of the filter tank 1 near the discharge pipe 2. It is used to facilitate the discharge of cleaning residues and maintain a clean internal environment when the end cover 3 is removed and the filter tank 1 is cleaned.

[0031] The second drain valve 6 is fixed on the lower surface of the filter tank 1 and communicates with the filter cartridge 7. It can discharge heavier impurities deposited inside the filter cartridge 7 in a timely manner, prevent impurities from accumulating at the bottom of the filter cartridge 7, extend the service life of the filter cartridge 7, and reduce the overall cleaning frequency.

[0032] The automatic cleaning mechanism 8 includes a bracket 81 and a connecting sleeve 82. One end of the bracket 81 is fixed to the inner wall of the filter tank 1, and the other end is fixedly connected to the connecting sleeve 82. Together, they provide stable mounting support for the gear 83 and rack 85, ensuring that the transmission structure does not wobble during operation and guaranteeing precise meshing between the gear 83 and rack 85. A protective soft shell, as is common in conventional technology, can be fitted over the rack 85 to prevent impurities from getting stuck between the rack 85 and gear 83. The gear 83 is rotatably connected inside the connecting sleeve 82, and its lower surface is fixed to the rotating brush 84. The brush surface of the rotating brush 84 is in close contact with the inner wall of the filter cartridge 7, and their axes are completely aligned. When the gear 83 rotates, it drives the rotating brush 84 to rotate synchronously. Conventional technology uses food-grade 316L stainless steel wire brushes suitable for hard filter media or acid-resistant silicone brushes suitable for soft filter media, balancing cleaning effect and corrosion resistance. The friction of the bristles removes clogging impurities from the filter holes on the inner wall of the filter cartridge 7, achieving automatic unclogging of the filter holes without manual intervention. The rack 85 is slidably connected inside the connecting sleeve 82 and meshes with the gear 83. The end away from the connecting sleeve 82 is fixed to the pressure plate 86. The pressure plate 86 slides in the first groove of the discharge pipe 2. When the flow rate of vinegar in the discharge pipe 2 changes, the pressure plate 86 will slide with the impact force, thereby driving the rack 85 to move. Through the meshing transmission between the rack 85 and the gear 83, the signal of "change in discharge volume" is converted into the action of "rotating brush 84 cleaning". The push column 87 is fixed to the pressure plate 86 away from the rack 85. On one side, it slides through the fixed plate 88, which restricts the sliding direction of the pressure plate 86; the fixed plate 88 is fixed to the inner wall of the discharge pipe 2, providing a support point for the return spring 89; the return spring 89 connects the fixed plate 88 and the pressure plate 86. After the pressure plate 86 slides due to the reduction of the discharge volume, it can drive the pressure plate 86 to return to its original state through its own elasticity, so that the rack 85, gear 83 and rotating brush 84 return to their initial state, preparing for the next cleaning action, and realizing the cyclic operation of the cleaning mechanism 8.

[0033] During use, first close the first drain valve 5 and the second drain valve 6 to ensure that the filter tank 1 is in a closed state. The vinegar to be filtered is then transported to the filter tank 1 using the matching discharge pump, maintaining a constant conveying pressure. It flows along the inclined surface of the filter cylinder 7 and enters the filter cylinder 7. Under pressure, the vinegar passes through the filter holes in the wall of the filter cylinder 7, where solid impurities are trapped and remain inside the filter cylinder 7 or adhere to the inner wall of the filter cylinder 7. The filtered clean vinegar enters the outside of the filter cylinder 7 and is finally discharged through the discharge pipe 2 to enter the subsequent production stage. At this time, the discharge pipe... When the vinegar flow rate inside the discharge pipe 2 is stable, the impact force on the pressure plate 86 is greater than the elastic force of the return spring 89, pushing the pressure plate 86 into the discharge pipe 2. The cleaning mechanism 8 does not start. As the filtration time increases, the filter holes on the inner wall of the filter cylinder 7 are gradually blocked by impurities, the filtration efficiency of the filter cylinder 7 decreases, the amount of vinegar discharged from the discharge pipe 2 decreases significantly, the vinegar flow rate inside the pipe decreases, and the impact force on the pressure plate 86 weakens. When the impact force is less than the elastic force of the return spring 89, the return spring 89 pushes the pressure plate 86 to slide along the first sliding groove towards the connecting sleeve 82. The push column 87 slides synchronously with the pressure plate 86 in the fixed plate 88. The rack 85 moves within the connecting sleeve 82. Since the rack 85 meshes with the gear 83, the movement of the rack 85 drives the gear 83 to rotate. The gear 83 drives the rotating brush 84 on its lower surface to rotate synchronously. The brush surface of the rotating brush 84 is in contact with the inner wall of the filter cylinder 7. During rotation, the bristles brush the filter holes on the inner wall of the filter cylinder 7, removing impurities clogged within. As the filter holes are gradually cleared, the filtration efficiency of the filter cylinder 7 recovers, the vinegar output from the discharge pipe 2 increases, and the vinegar flow rate in the pipe accelerates. The impact force on the pressure plate 86 again exceeds the elastic force of the return spring 89, and the impact force pushes the pressure plate 86 to slide in the opposite direction, carrying... The moving rack 85 moves back, and the gear 83 and rotating brush 84 rotate in the opposite direction to their initial positions. The return spring 89 is retracted and stored energy, and the equipment returns to normal filtration. One blockage can be cleared without stopping the machine, achieving continuous filtration. After the equipment has been running continuously for a period of time, the second drain valve 6 is opened to discharge the heavier impurities deposited inside the filter cartridge 7. After the impurities are discharged, the second drain valve 6 is closed, and the equipment continues to perform filtration. If the filtration efficiency of the filter cartridge 7 continues to decline, the end cover 3 can be removed again to perform deep cleaning or replacement of the filter cartridge 7 or rotating brush 84 to ensure long-term stable operation of the equipment.
