Description

Technical Field

[0001] This utility model relates to the technical field of fruit juice production, and in particular to a fruit pulp fiber filtration device. Background Technology

[0002] In the production of fruit juice, the fruit first needs to be crushed and juiced. Then, the juice needs to be filtered through a filtration device to remove the pulp and fiber, improving the clarity and taste. In the prior art, utility model patent application number 201921279466.4 discloses a pulp filtration device for fruit juice beverage processing, which mainly consists of a box and a filter screen. When filtering juice, the juice is poured into the box, then falls onto the filter screen. Solid fibers and juice remain at the top of the filter screen, while the remaining juice falls to the bottom, completing the filtration process. However, this device has the following problems: it relies solely on the diffusion effect of the juice itself on the filter screen, resulting in low filtration speed and inconvenience. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a fruit pulp fiber filtering device that promotes the filtration speed of fruit juice by reducing the pressure in the chamber of the filter body during fruit juice filtration. It is easy to use and highly practical.

[0004] This utility model discloses a fruit pulp fiber filtering device, comprising a base plate, a support, and a housing. The housing is fixedly mounted on the upper part of the base plate via the support, and a chamber is provided inside the housing. It also includes a vacuum pump, a conveying mechanism, a discharging mechanism, and a filtering mechanism. The filtering mechanism is mounted on the housing and has a filtering function. The vacuum pump is mounted on the housing, and its input end is connected to the chamber of the housing. The conveying mechanism is used to convey fruit juice into the chamber of the housing, and the discharging mechanism is used to discharge the fruit juice from the chamber of the housing. When fruit juice needs to be filtered, the conveying mechanism conveys the fruit juice to the filtering mechanism, allowing the filtering mechanism to filter out the fiber and pulp contained in the fruit juice, causing the liquid fruit juice to flow into the chamber of the housing. The fruit juice is then discharged from the chamber of the housing through the discharging mechanism. When the filtering mechanism is filtering fruit juice, the vacuum pump is turned on to reduce the pressure inside the chamber of the housing, making the pressure inside the filtering mechanism greater than the pressure inside the housing, thus accelerating the filtration speed of the fruit juice. This device, by reducing the pressure inside the chamber of the housing during fruit juice filtration, promotes the filtration speed of the fruit juice through the filtering mechanism, making it convenient to use and highly practical.

[0005] Preferably, the filtration mechanism includes a filter cylinder, a connecting frame, a sealing cover, a hydraulic cylinder, a push rod, and a sliding plate. The filter cylinder is fixedly mounted on the housing via the connecting frame. Both the upper and lower ends of the filter cylinder are open. The filter cylinder has an internal cavity and multiple sets of filter holes communicating with the cavity. These filter holes are all located within the housing cavity. The sealing cover is bolted to the opening at the upper end of the filter cylinder. The hydraulic cylinder is fixedly mounted on the base plate. The push rod is slidably mounted on the housing, with its lower end connected to the output end of the hydraulic cylinder. The sliding plate is slidably mounted within the cavity of the filter cylinder, and a sealed sliding connection is formed between the sliding plate and the cavity of the filter cylinder. The sliding plate is fixedly installed at the upper end of the push rod. When filtering juice, the juice is conveyed into the cavity of the filter cylinder by the conveying mechanism. Then, the juice flows into the chamber of the box through multiple sets of filter holes on the filter cylinder. Solid fibers and pulp in the juice remain in the cavity of the filter cylinder. When it is necessary to clean the pulp and fibers in the cavity of the filter cylinder, stop conveying juice into the conveying pipe, open the sealing cover, and then open the hydraulic cylinder. The hydraulic cylinder pushes the sliding plate up through the push rod, so that the sliding plate rises to the opening near the upper end of the filter cylinder. Then, the staff can clean the pulp and fibers on the filter cylinder. This facilitates the filtration of juice and the cleaning of pulp and fibers.

[0006] Preferably, the conveying mechanism includes a water tank, a conveying pump, and a conveying pipe. The water tank is fixedly installed on the base plate. The input end of the conveying pump is connected to the water tank, and the output end of the conveying pump is connected to the conveying pipe. A valve is installed on the conveying pipe, and the output end of the conveying pipe is connected to the upper part of the filter cylinder cavity. When it is necessary to convey juice into the filter cylinder, the conveying pump is turned on, so that the juice in the water tank is conveyed sequentially through the conveying pump and the conveying pipe into the cavity of the filter cylinder, and the juice is located above the sliding plate in the cavity of the filter cylinder, which facilitates the conveying of juice.

[0007] Preferably, the discharge mechanism includes a water pump, a drain pipe, and a discharge pipe. The water pump is fixedly installed on the base plate. The input end of the water pump is connected to the lower part of the chamber through the drain pipe, and the output end of the water pump is connected to the discharge pipe. When it is necessary to discharge the filtered juice in the chamber, the water pump is turned on, so that the juice in the chamber is discharged to the outside through the drain pipe, the water pump, and the discharge pipe in sequence and then collected. This facilitates the discharge of the juice.

[0008] Preferably, the diameter of the multiple sets of filter holes on the filter cylinder gradually increases from top to bottom. In the process of producing juice, some juices that promote digestion need to contain some fruit fiber and pulp. Therefore, when filtering juice, the pore size of the filter is determined according to the production requirements of the juice. When filtering juice through the filter cylinder, the higher the position of the sliding plate, the less coarse fiber and the smaller the pulp particles in the juice. When the sliding plate is lower, some coarse fiber in the juice can enter the chamber of the box through the larger pores on the filter cylinder. Juice containing coarse fiber is suitable for producing beverages that promote digestion. The filtration precision can be adjusted according to production needs. It is convenient to use, has low limitations, and is highly practical.

[0009] Preferably, the enclosure is provided with an observation window; this facilitates the monitoring of the operating status of the equipment inside the enclosure.

[0010] Preferably, the sealing cover is provided with a handle and a sealing gasket is provided at the lower end of the sealing cover; the above configuration improves the sealing performance between the sealing cover and the filter cartridge, and facilitates the removal and placement of the sealing cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when filtering juice, by reducing the pressure in the chamber of the box, the filtration speed of the juice on the filtration mechanism is promoted, making it convenient to use and highly practical.

[0021] like Figures 1 to 6 The fruit pulp fiber filtering device of this utility model includes a base plate 1, a support 2, a housing 3, a vacuum pump 4, a conveying mechanism, a discharge mechanism, and a filtering mechanism. The housing 3 is fixedly installed on the upper end of the base plate 1 via the support 2. A chamber is provided inside the housing 3. The filtering mechanism is installed on the housing 3 and has a filtering function. The vacuum pump 4 is installed on the housing 3, and the input end of the vacuum pump 4 is connected to the chamber of the housing 3. The conveying mechanism is used to convey fruit juice into the chamber of the housing 3, and the discharge mechanism is used to discharge the fruit juice from the chamber of the housing 3. When fruit juice needs to be filtered, the fruit juice is conveyed through the conveying mechanism. The juice is fed into the filtration mechanism, where it filters out the fiber and pulp, allowing the liquid juice to flow into chamber 3 of the housing. The juice is then discharged from chamber 3 via the discharge mechanism. When the filtration mechanism is filtering the juice, the vacuum pump 4 is activated to reduce the pressure within chamber 3, ensuring the pressure inside the filtration mechanism is greater than the pressure inside chamber 3, thus accelerating the filtration process. This method, by reducing the pressure within chamber 3, promotes faster filtration of the juice, making it convenient and highly practical.

[0022] like Figure 3 and Figure 5The filtration mechanism includes a filter cylinder 5, a connecting frame 6, a sealing cover 7, a hydraulic cylinder 8, a push rod 9, and a sliding plate 10. The filter cylinder 5 is fixedly installed on the housing 3 via the connecting frame 6. Both the upper and lower ends of the filter cylinder 5 are open. The filter cylinder 5 has an internal cavity with multiple sets of filter holes communicating with the cavity. These filter holes are all located within the cavity of the housing 3. The sealing cover 7 is bolted to the opening at the upper end of the filter cylinder 5. The hydraulic cylinder 8 is fixedly installed on the base plate 1. The push rod 9 is slidably installed on the housing 3, with its lower end connected to the output end of the hydraulic cylinder 8. The sliding plate 10 is slidably installed within the cavity of the filter cylinder 5, with a sealed sliding relationship between the sliding plate 10 and the cavity of the filter cylinder 5. The sliding plate 10 is fixedly installed on the upper end of the push rod 9. When filtering juice, the juice is conveyed into the cavity of the filter cylinder 5 through the conveying mechanism. Then, the juice flows into the chamber of the box 3 through multiple sets of filter holes on the filter cylinder 5. The solid fibers and pulp in the juice remain in the cavity of the filter cylinder 5. When it is necessary to clean the pulp and fibers in the cavity of the filter cylinder 5, stop conveying juice into the conveying pipe 13, open the sealing cover 7, and then open the hydraulic cylinder 8. The hydraulic cylinder 8 raises the sliding plate 10 through the push rod 9, so that the sliding plate 10 rises to the opening near the upper end of the filter cylinder 5. Then, the staff can clean the pulp and fibers on the filter cylinder 5. This facilitates the filtration of juice and the cleaning of pulp and fibers.

[0023] like Figure 1 and Figure 3 The conveying mechanism includes a water tank 11, a conveying pump 12, and a conveying pipe 13. The water tank 11 is fixedly installed on the base plate 1. The input end of the conveying pump 12 is connected to the water tank 11, and the output end of the conveying pump 12 is connected to the conveying pipe 13. A valve is installed on the conveying pipe 13, and the output end of the conveying pipe 13 is connected to the upper part of the cavity of the filter cylinder 5. When it is necessary to convey juice into the filter cylinder 5, the conveying pump 12 is turned on, so that the juice in the water tank 11 is conveyed sequentially through the conveying pump 12 and the conveying pipe 13 into the cavity of the filter cylinder 5, and the juice is located above the sliding plate 10 in the cavity of the filter cylinder 5, which facilitates the conveying of juice.

[0024] like Figure 1 and Figure 6 The discharge mechanism includes a water pump 14, a drain pipe 15, and a discharge pipe 16. The water pump 14 is fixedly installed on the base plate 1. The input end of the water pump 14 is connected to the lower part of the chamber 3 of the box through the drain pipe 15, and the output end of the water pump 14 is connected to the discharge pipe 16. When it is necessary to discharge the filtered juice in the chamber 3 of the box, the water pump 14 is turned on, so that the juice in the chamber 3 of the box is discharged to the outside through the drain pipe 15, the water pump 14, and the discharge pipe 16 in sequence and then collected. This facilitates the discharge of the juice.

[0025] like Figure 3The diameter of the multiple sets of filter holes on the filter cylinder 5 gradually increases from top to bottom. In the process of producing juice, some juices that promote digestion need to contain some fruit fiber and pulp. Therefore, when filtering juice, the pore size is determined according to the production requirements of the juice. When filtering juice through the filter cylinder 5, the higher the position of the sliding plate 10, the less coarse fiber and the smaller the pulp particles in the juice. When the sliding plate 10 is lower, some coarse fiber in the juice can enter the chamber of the box 3 through the larger diameter filter holes on the filter cylinder 5. Juice containing coarse fiber is suitable for producing beverages that promote digestion. The filtration precision can be adjusted according to the production needs. It is convenient to use, has low limitations, and is highly practical.
