Description

Technical Field

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

[0002] Grape juice is obtained by pressing grapes, but simple pressing results in grape juice containing impurities such as grape seeds and skins, which affects the taste. Therefore, it is necessary to filter the grape juice after pressing.

[0003] The traditional filtration method in the existing technology is to use a flat filter screen for filtration. However, the filtration effect of a flat filter screen is limited. Nowadays, some companies on the market use a rotating cylindrical filter screen to filter juice. Although this increases the filtration speed, the impurities attached to the inner wall of the cylindrical filter screen are difficult to clean during operation. Generally, it is necessary to stop the machine for cleaning, which undoubtedly reduces the working efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a grape juice filtration device for wine production.

[0005] The technical solution of this utility model is a grape juice filtration device for wine production, comprising:

[0006] The filter barrel has a feed hopper connected to it; a support is installed at the bottom of the filter barrel.

[0007] The filter cartridge is located inside the filter barrel. Its upper part is a circular tube structure and its lower part is a funnel structure. The bottom end of the filter cartridge is connected to a slag discharge pipe. The slag discharge pipe is rotatably installed on the filter barrel and moves through the bottom of the filter barrel. The filter barrel is equipped with a power component for driving the slag discharge pipe to rotate.

[0008] The sealing mechanism includes an electric push rod, a vertical rod, a first sealing block, and a second sealing block. The vertical rod is vertically installed inside the filter cartridge. Both the first and second sealing blocks are installed on the vertical rod. The second sealing block is located below the first sealing block. The upper part of the second sealing block is frustum-shaped. The electric push rod is installed on the filter cartridge and its output shaft is connected to the vertical rod.

[0009] A receiving hopper is located below the filter hopper and is connected to the filter hopper. A filter screen is installed inside the receiving hopper.

[0010] A liquid conveying device mounted on a bracket to transport liquid from inside the receiving tank to the inside of the filter cartridge.

[0011] Preferably, an outer pipe is connected to the bottom of the feed hopper, an inner pipe is provided inside the outer pipe, the inner pipe is fixedly connected to the outer pipe, and an annular plate is provided at the bottom of the inner pipe.

[0012] Preferably, a scraper is provided on the inner side of the filter cartridge, and the scraper is fixedly connected to the upper end of the inner wall of the filter cartridge.

[0013] Preferably, a coarse mesh filter is installed on the inner side of the feed hopper.

[0014] Preferably, the liquid conveying device includes a pump, a first pipe and a second pipe. The pump is mounted on a bracket. The input end of the first pipe is connected to the bottom end of the receiving tank through the first pipe. The second pipe is connected to the output end of the pump.

[0024] Example 1

[0025] like Figures 1-3 As shown in the figure, the grape juice filtration equipment for wine production proposed in this embodiment includes a filter barrel 1, a filter cylinder 4, a receiving barrel 5, a sealing mechanism, and a liquid conveying device.

[0026] A drain pipe 20 is connected to the bottom of the filter bucket 1, and a valve 22 is installed on the drain pipe 20. A feed hopper 2 is connected to the filter bucket 1, and a coarse filter screen 6 is installed on the inner side of the feed hopper 2. The coarse filter screen 6 can achieve coarse filtration of the juice. A support 3 is provided at the bottom of the filter bucket 1.

[0027] The filter cylinder 4 is located inside the filter barrel 1. Its upper part is a circular tube structure and its lower part is a funnel structure. The bottom end of the filter cylinder 4 is connected to a slag discharge pipe 15. The slag discharge pipe 15 is rotatably mounted on the filter barrel 1 and moves through the bottom of the filter barrel 1. A sealing ring for sealing the slag discharge pipe 15 is installed at the bottom end of the filter barrel 1. A power component for driving the slag discharge pipe 15 to rotate is installed on the filter barrel 1. The power component includes a servo motor 16, a gear 17 and a gear ring 18. The servo motor 16 is installed at the bottom end of the filter barrel 1. The gear 17 is installed on the output shaft of the servo motor 16. The gear ring 18 is installed on the outer circumference of the slag discharge pipe 15 and meshes with the gear 17.

[0028] The sealing mechanism includes an electric push rod 7, a vertical rod 11, a first sealing block 13, and a second sealing block 14. The vertical rod 11 is vertically arranged inside the filter cartridge 4. The first sealing block 13 and the second sealing block 14 are both arranged on the vertical rod 11. The second sealing block 14 is located below the first sealing block 13. Sealing rings are installed on the outer periphery of both the second sealing block 14 and the first sealing block 13. The upper part of the second sealing block 14 is frustum-shaped. The electric push rod 7 is installed on the filter cartridge 1 and its output shaft is connected to the vertical rod 11.

[0029] The receiving bucket 5 is located below the filter bucket 1 and is connected to the filter bucket 1. A filter screen 21 is provided inside the receiving bucket 5.

[0030] The liquid conveying device is installed on the bracket 3 to convey the liquid inside the receiving tank 5 to the inside of the filter cartridge 4. The liquid conveying device includes a pump 19, a first pipe 191 and a second pipe 192. The pump 19 is installed on the bracket 3. The input end of the first pipe 191 is connected to the bottom end of the receiving tank 5 through the first pipe 191. The second pipe 192 is connected to the output end of the pump 19. The other end of the second pipe 192 is located above the inside of the filter cartridge 4.

[0031] Alternatively, in this technical solution, the liquid conveying device can be omitted to re-transport the juice into the filter cartridge 4. Alternatively, a pipe can be connected to the bottom of the receiving tank 5, and a valve can be installed on the pipe. After opening the valve, the liquid inside the receiving tank 5 can be discharged and collected.

[0032] In this technical solution, a PLC controller is used to control the equipment.

[0033] In this embodiment, the grape juice to be filtered is poured into the inner side of the filter cylinder 4 through the feed hopper 2. The juice is filtered through several fine holes on the filter cylinder 4. Since the filter cylinder 4 is barrel-shaped and the bottom of the filter cylinder 4 is funnel-shaped, its filtration area is obviously larger than that of a traditional flat filter screen, thereby improving the filtration speed.

[0034] When filtering the juice, the slag discharge pipe 15 can be driven to rotate by the set power component, and the slag discharge pipe 15 in turn drives the filter cylinder 4 to rotate. Under the action of centrifugal force, the filtration speed of the liquid can be accelerated.

[0035] Impurities adhering to the inner surface of the filter cartridge 4 will slide down to the bottom center of the filter cartridge 4 under the action of gravity. When cleaning the impurities inside the filter cartridge 4, the electric push rod 7 is activated to drive the vertical rod 11, the first sealing block 13, and the second sealing block 14 to move downwards simultaneously. The impurities then enter the slag discharge pipe 15. As the electric push rod 7 continues to drive, when the first sealing block 13 moves to the inside of the slag discharge pipe 15, the upper end of the slag discharge pipe 15 is blocked, and the liquid inside the filter cartridge 4 can no longer flow out. When the second sealing block 11... 4. After moving to the position below the slag discharge pipe 15, impurities and a small amount of juice inside the slag discharge pipe 15 flow into the receiving bucket 5. Then, the first sealing block 13 and the second sealing block 14 are quickly driven to reset. The filter screen 21 can filter out the impurities, allowing the juice to flow to the bottom of the receiving bucket 5. After the pump 19 is started, the juice can be transported back to the inside of the filter cartridge 4. Through the above structure, the equipment can still achieve automatic slag discharge without stopping the filtration operation, thereby ensuring the filtration efficiency of the equipment.

[0036] Example 2

[0037] like Figure 3 As shown in this embodiment, a grape juice filtration device for wine production is proposed. Compared with Embodiment 1, in this embodiment, the bottom end of the feed hopper 2 is connected to an outer pipe 8, and an inner pipe 9 is provided inside the outer pipe 8. The inner pipe 9 is fixedly connected to the outer pipe 8, and an annular plate 10 is provided at the bottom end of the inner pipe 9. The annular plate 10 is located on the upper part of the inner side of the filter cylinder 4, and there is a gap between the annular plate 10 and the inner wall of the filter cylinder 4. A portion of the juice flows into the bottom end of the inner side of the filter cylinder 4 through the inner pipe 9 and is filtered through the fine holes at the bottom end of the filter cylinder 4. Another portion of the juice flows into the annular plate 10 through the cavity between the inner pipe 9 and the outer pipe 8, and finally slides down the inner wall of the filter cylinder 4. The juice is filtered out through the fine holes on the inner wall of the filter cylinder 4. By setting the above structure, the contact area between the filter cylinder 4 and the juice can be increased, thereby increasing the filtration speed of the juice.

[0038] Example 3

[0039] like Figure 3 As shown in this embodiment, a grape juice filtration device for wine production is proposed. Compared with the first embodiment, in this embodiment, a scraper 12 is provided on the inner side of the filter cylinder 4. The scraper 12 is fixedly connected to the upper end of the inner wall of the filter barrel 1. During the rotation of the filter cylinder 4, the scraper 12 and the filter cylinder 4 rotate relative to each other. The scraper 12 can scrape the residue on the inner wall of the filter cylinder 4 to the bottom of the filter cylinder 4, thereby facilitating subsequent cleaning. However, it is worth noting that when the filter cylinder 4 is severely clogged, the machine should be stopped and manual cleaning should be carried out.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
