Description

Technical Field

[0001] This utility model relates to the field of pickling tank feeding technology, and in particular to a pickling tank feeding mechanism. Background Technology

[0002] In the field of candied fruit processing, pickling is a crucial process that determines the product's taste, flavor, and shelf life. The pickling tank, as a core piece of equipment, has a feeding mechanism that directly affects the efficiency, concentration stability, and resource utilization of the sugar syrup. During the pickling process, sugar syrup needs to be continuously replenished into the tank to maintain the set concentration. Simultaneously, some of the old sugar syrup needs to be replaced periodically to prevent impurities from accumulating and affecting product quality. Therefore, the feeding mechanism of the pickling tank must integrate functions such as sugar syrup delivery, concentration control, and recycling. It is a vital support for ensuring the large-scale, standardized production of candied fruit, and its performance directly affects the production costs and product quality of processing enterprises. In existing technologies, the feeding mechanism of the pickling tank mostly adopts a "one-way conveying + manual control" mode to add and replace sugar water. Specifically, this type of mechanism is usually only equipped with a single set of water suction pipe and water inlet pipe. The water suction pipe is connected to a water pump to directly extract the old sugar water in the tank and discharge it directly into the wastewater treatment system. The new sugar water is stored in a separate storage tank. The amount to be added is judged by manually observing the sugar water level in the tank or by experience. After opening the water inlet valve, the new sugar water is injected into the tank. Although some optimized mechanisms are equipped with a single-layer filter screen at the end of the water suction pipe, it can only intercept larger volumes of candied fruit pulp and cannot filter out small fruit pulp fragments and sugar crystals. Moreover, the mixing ratio of new and old sugar water depends entirely on manual calculation and manual valve adjustment, lacking precise control methods. However, the existing structure and operation of the technology have obvious drawbacks: significant waste of old sugar water resources and difficulty in ensuring the accuracy of the new sugar water ratio. On the one hand, although the concentration of old sugar water has decreased, it still contains a certain amount of sugar and effective ingredients. Direct discharge not only wastes a large amount of sugar water resources but also increases the cost and difficulty of wastewater treatment. On the other hand, when manually controlling the amount of new sugar water added, the concentration of sugar water in the tank is prone to large fluctuations due to observation errors, operation delays, and other factors. Too high a concentration leads to excessive sugar content in the candied fruit, while too low a concentration affects the pickling effect and the shelf life of the product, making it difficult to meet the strict requirements for concentration stability in candied fruit processing. Therefore, a feeding mechanism for the pickling tank is proposed to solve the above problems. Utility Model Content

A second conveying pipe is fixedly connected to the side wall of the new sugar water tank, and a second water pump is mounted on the side wall of the second conveying pipe. The output end of the second water pump is fixedly connected to the other end of the inlet pipe.

[0005] By adopting the above technical solution, the old sugar water and the new sugar water can be mixed, thereby reducing the amount of new sugar water used.

[0009] By adopting the above technical solution, the old sugar water after extraction was filtered.

[0010] The first input end of the water pump is fixedly connected to the other end of the water pumping pipe, and the second input end of the water pump is fixedly connected to one end of the second delivery pipe.

[0011] By adopting the above technical solution, the effect of delivering sugar water was achieved.

[0012] Preferably, a bracket is fixedly connected to the side wall of the filter tube, and a hollow tube is rotatably connected inside the bracket, with the side wall of the pumping pipe slidably connected inside the hollow tube.

[0013] The above technical solution is used to restrict the position of the water pumping pipe and prevent it from falling off.

[0014] Preferably, a connecting plate is fixedly connected to the side wall of the hollow tube, and the top of the scraper is fixedly connected to the bottom of the connecting plate.

Then, it is combined with the new sugar water in the new sugar water tank and mixed in proportion controlled by the proportional valve. Finally, it is returned to the pool through the water pump two and the water inlet pipe, thereby realizing the reuse of old sugar water and the precise addition of new sugar water, solving the problems of waste of old sugar water and difficulty in the proportion of new sugar water, and improving the utilization rate of sugar water resources and the accuracy of addition.

[0021] 2. In this utility model, the motor at the top of the starter bracket drives gear one to rotate, which in turn drives the hollow tube to rotate through meshing gear two. The hollow tube then drives the connecting plate and the bottom scraper to rotate and scrape off the debris inside the filter tube. In conjunction with the silicone gasket inside the filter tube holes, the generation of debris is reduced, thereby achieving the effect of double protection for the unobstructed flow of the filter tube holes. This solves the problem that existing filter tubes are prone to blockage by debris, which leads to poor flow of sugar water. The above structure improves the efficiency of sugar water delivery and the convenience of filter tube maintenance. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] A feeding mechanism for a pickling tank, as described in the following example. Figures 1-3 The system includes a tank 1, which is made of food-grade 304 stainless steel. Its function is to provide a sealed space for pickling candied fruit, ensuring hygiene during the pickling process and preventing the sugar water from leaking out. The side wall of the tank 1 is equipped with a circulation component for extracting, filtering, mixing and returning the sugar water, achieving the effect of sugar water recycling and precise addition. The tank 1 is equipped with a filter pipe 2, which allows the sugar water in the tank 1 to enter the pipe while blocking the candied fruit from entering, preventing the candied fruit from flowing with the sugar water and causing subsequent pipe blockage. The filter pipe 2 is equipped with an anti-clogging component to remove candied fruit debris attached to the inner wall of the filter pipe 2, preventing the holes of the filter pipe 2 from being blocked and ensuring smooth flow of sugar water. The circulation assembly includes a suction pipe 3 and an inlet pipe 15. The suction pipe 3 is a food-grade PVC flexible hose. One end of both the suction pipe 3 and the inlet pipe 15 is located inside the tank body 1. The suction pipe 3 is used to extract the old sugar water from the tank body 1. A water pump 4 is installed on the side wall of the suction pipe 3. The water pump 4 is an ISG50-160 type vertical pipeline centrifugal pump, which provides power for the extraction and transportation of the old sugar water. A filter box 5 is fixedly connected to the output end of the water pump 4. The filter box 5 is used to hold the filter screen and filter the old sugar water. A conveying pipe 7 is fixedly connected to the side wall of the filter box 5. A food-grade PVC rigid pipe is used to transport the filtered clean old sugar water in the filter box 5. One end of the transport pipe 7 is fixedly connected to a transfer storage tank 8, which is used to temporarily store the filtered clean old sugar water, providing buffer space for subsequent mixing with new sugar water. A connecting pipe 9, which is made of food-grade stainless steel, is fixedly connected to the side wall of the transfer storage tank 8. One end of the connecting pipe 9 is fixedly connected to a new sugar water tank 11, which is made of food-grade 304 stainless steel. The new sugar water tank 11 is used to store the new sugar water and mix it with the old sugar water. The top of the new sugar water tank 11 has an inlet 12 for feeding. Inlet 12 is used to inject new sugar water into the new sugar water tank 11, facilitating the replenishment of new sugar water by operators. A proportional valve 10 is installed on the side wall of connecting pipe 9. The proportional valve 10 is a VA3200 electric proportional regulating valve, used to regulate the flow rate of old sugar water from the intermediate storage tank 8 into the new sugar water tank 11. This, combined with the new sugar water in the new sugar water tank 11, ensures that the old and new sugar water are mixed in a set ratio, achieving precise control of the sugar water concentration. A second conveying pipe 13, a food-grade PVC rigid pipe, is fixedly connected to the side wall of the new sugar water tank 11 to transport the mixed sugar water from the new sugar water tank 11. The conveying system includes a second pump 14 installed on the side wall of the second conveying pipe 13. The second pump 14 is an ISG40-125 vertical pipeline centrifugal pump, which provides power for the conveying of the mixed sugar water. After pressurizing the mixed sugar water, it is conveyed to the inlet pipe 15. The output end of the second pump 14 is fixedly connected to the other end of the inlet pipe 15. The inlet pipe 15 is a food-grade PVC hose, which is used to return the mixed sugar water to the tank 1 to complete the circulation and feeding of the sugar water. The input end of the first pump 4 is fixedly connected to the other end of its pumping pipe 3, and the input end of the second pump 14 is fixedly connected to one end of the second conveying pipe 13. A cover plate 6 is rotatably connected to the side wall of the filter box 5. The cover plate 6 is made of food-grade 304 stainless steel and has a rubber sealing gasket between it and the filter box 5. This is used to open or close the filter box 5, making it convenient for operators to remove the filter screen for cleaning or replacement. At the same time, it ensures the airtightness of the filter box 5 and prevents the sugar water from leaking. Inside the filter box 5, filter screen 16 and filter screen 17 are slidably connected. Filter screen 16 is a 100-mesh stainless steel woven filter screen, which is used to intercept larger impurities such as candied fruit fragments and fruit pulp fibers in the old sugar water. Filter screen 17 is a 200-mesh stainless steel woven filter screen, which is used to further filter fine particulate impurities in the old sugar water. Filter screen 16 and filter screen 17 work together to perform graded filtration, which achieves the effect of thoroughly removing impurities from the old sugar water, ensuring the purity of the subsequent sugar water, and preventing impurities from affecting the quality of candied fruit pickling.

[0026] Reference Figures 4-5 The anti-clogging component includes a scraper 21, which is made of a composite of food-grade silicone and hard plastic. The scraper 21 is slidably connected to the inner wall of the filter tube 2, and is used to scrape off the attached candied fruit residue from the inner wall of the filter tube 2, preventing the residue from clogging the holes of the filter tube 2 and ensuring that the inside of the filter tube 2 is unobstructed. The filter tube 2 is made of food-grade 304 stainless steel and its function is to separate the candied fruit from the sugar water, ensuring that the sugar water can enter the tube while the candied fruit is blocked. The filter tube 2 has multiple holes inside, and each hole is filled with silicone. The rubber gasket, made of medical-grade silicone, is used to cushion the impact between the candied fruit and the edge of the holes, reducing damage to the candied fruit's skin and the generation of fragments. It also prevents wear on the hole edges due to long-term friction, achieving the dual effect of extending the service life of the filter tube 2 and reducing the source of impurities. A bracket 18 is fixedly connected to the side wall of the filter tube 2. A hollow tube 19 is rotatably connected inside the bracket 18. The hollow tube 19 is made of food-grade stainless steel, with an inner diameter slightly larger than the outer diameter of the water suction pipe 3. The side wall of the water suction pipe 3 is slidably connected inside the hollow tube 19. 9 serves to guide and protect the water suction pipe 3, preventing it from colliding with the filter pipe 2 due to shaking during the extraction of sugar water. It also provides a stable extraction channel for the water suction pipe 3. A connecting plate 20 is fixedly connected to the side wall of the hollow pipe 19. The top of the scraper 21 is fixedly connected to the bottom of the connecting plate 20. The connecting plate 20 rotates in conjunction with the scraper 21, allowing the scraper 21 to evenly scrape away debris along the inner wall of the filter pipe 2. A motor 22 is fixedly connected to the top of the bracket 18. The motor 22 is a JGA25-370 miniature motor. The geared motor provides a power source for the anti-clogging components. Gear 23 is fixedly connected to the output end of the motor 22. Gear 23 is used to transmit the power of the motor 22. Gear 24 is fixedly connected to the side wall of the hollow tube 19. Gear 24 meshes with gear 23. Gear 23 and gear 24 mesh to transmit the motion. The speed reduction and torque increase are achieved by the difference in the number of gear teeth, so that the hollow tube 19 can rotate at a suitable speed. This ensures that the scraper 21 can effectively scrape off the debris without damaging the inner wall of the filter tube 2 due to excessive speed.

[0027] Working principle: Before the mechanism starts the sugar water circulation, the candied fruit residue on the inner wall and holes of the filter tube 2 must be removed by the anti-clogging component to avoid blockage and affect the flow of sugar water. By starting the motor 22 fixed on the top of the bracket 18, the output end of the motor 22 drives the gear 1 23 to rotate. Since the gear 1 23 meshes with the gear 24 fixed on the side wall of the hollow tube 19, the rotation of the gear 1 23 will synchronously drive the hollow tube 19 to rotate inside the bracket 18. The connecting plate 20 fixed on the side wall of the hollow tube 19 rotates with the hollow tube 19, which in turn drives the scraper 21 fixed at the bottom of the connecting plate 20 to rotate. The side wall of the scraper 21 always slides against the inner wall of the filter tube 2. During the rotation, the candied fruit residue attached to the inner wall of the filter tube 2 can be scraped off. At the same time, the silicone gasket in the hole of the filter tube 2 can reduce the direct collision between the candied fruit and the edge of the hole, reduce the amount of residue generated, and doubly ensure the unobstructed flow of the holes of the filter tube 2, laying the foundation for the subsequent flow of sugar water. After the anti-clogging component completes the pretreatment, the circulation component is activated to extract and filter the old sugar water. By turning on water pump 4, the old sugar water in tank 1 is extracted through water pipe 3. After being pressurized by water pump 4, the old sugar water is transported to filter box 5. Inside filter box 5, filter screen 16 and filter screen 2 17, which are slidably connected, perform graded filtration of the old sugar water. Filter screen 16 first intercepts larger impurities such as candied fruit fragments and fruit pulp fibers, while filter screen 2 17 further filters fine particles. After filtration, the clean old sugar water is transported through conveying pipe 7 to transfer storage tank 8 for temporary storage. If it is necessary to clean the impurities in filter box 5, the cover plate 6 on the side wall of filter box 5 can be rotated to remove filter screen 16 and filter screen 2 17 for cleaning or replacement. The new sugar water is injected into the new sugar water tank 11 through the feed inlet 12 at the top of the new sugar water tank 11. The proportion valve 10 is adjusted according to the pickling requirements to set the mixing ratio of the old and new sugar water, such as 30% old sugar water and 70% new sugar water. After the proportion valve 10 is opened, the old sugar water in the transfer storage tank 8 and the new sugar water tank 11 are mixed in the set ratio through the connecting pipe 9. The mixed sugar water is temporarily stored in the new sugar water tank 11. Then, the second water pump 14 is started to draw the mixed sugar water through the second conveying pipe 13, and then the mixed sugar water is returned to the tank 1 through the water inlet pipe 15 to complete one sugar water circulation and feeding process.
