A filtration device for producing concentrated slurry

Abstract

This utility model discloses a filtration device for concentrated slurry production, including a filter box. A centrifugal rotating component is installed on the top of the filter box. An outer filter screen and an inner filter screen are installed inside the filter box via the centrifugal rotating component. A cover plate is fixedly installed on the top of the filter box, and a scraper-type inlet / outlet component is installed inside the cover plate. Both the liquid inlet end of the drain pipe and the liquid inlet end of the water inlet pipe are fixedly equipped with connecting flanges. Impurities attached to the inner and outer filter screens are scraped off by the scraper-type inlet / outlet component in conjunction with the rotating inner and outer filter screens. Water is transported to the interior through the water inlet pipe to rinse the unscraped impurities on the inner and outer filter screens. The impurities are then discharged from the filter box through the scraper-type inlet / outlet component via a water flow carrying device. This makes the inner and outer filter screens cleaner, avoiding the situation where dead corners are easily missed by manual scraping, and avoiding the situation where fine particles may be embedded deep in the filter pores due to simple backflushing cleaning.

Description

Technical Field

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

[0002] Beverage concentrate is a highly concentrated liquid raw material, usually made from basic ingredients such as fruits, grains, dairy products, and plant extracts through processes such as crushing, boiling, filtering, and concentration. Its water content is much lower than that of the original materials, and its flavor and nutrients (such as sugars, flavor substances, and some active ingredients) are highly preserved and concentrated. However, beverage concentrate may contain impurities, so it is necessary to filter it.

[0003] Beverage concentrates are typically filtered using filtration equipment. However, due to the high viscosity of beverage concentrates, centrifugal filtration equipment is often used to filter them, which speeds up the filtration process. After filtration, impurities remain inside the centrifugal filter screen. Since high-viscosity concentrates have poor fluidity, the filter cake tends to clump and adhere to the surface of the filter screen, requiring staff to clean the impurities.

[0004] Traditional cleaning methods mostly involve manual scraping in plate and frame filter presses or backflushing in centrifugal filters. These methods do not thoroughly remove residual impurities from the filter screen surface. Manual scraping is prone to missing dead corners, and backflushing may cause fine particles to embed deep into the filter pores. Based on the above problems, this application proposes a filtration device for slurry production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filtration device for slurry production, which solves the aforementioned problems.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This filtration equipment for slurry production uses a scraper-type inlet and outlet component in conjunction with a rotating inner and outer filter screen to scrape off impurities. Water is then transported to the interior through the inlet pipe to rinse the unscraped impurities on the inner and outer filter screens. The water is then carried out of the filter box through the scraper-type inlet and outlet component by a water flow carrying device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4A filtration device for producing concentrated slurry includes a filter box 1. A centrifugal rotating assembly is installed on the top of the filter box 1. An outer filter screen 6 and an inner filter screen 7 are arranged inside the filter box 1 via the centrifugal rotating assembly. The radius of the inner filter screen 7 is smaller than the radius of the outer filter screen 6, and the mesh radius of the inner filter screen 7 is larger than the mesh radius of the outer filter screen 6. Both the outer filter screen 6 and the inner filter screen 7 are made of stainless steel. A cover plate is fixedly installed on the top of the filter box 1, and a scraper-type inlet / outlet assembly is installed inside the cover plate. A drain pipe 23 and a water inlet pipe 24 are fixedly installed on the left and right sides of the filter box 1, respectively. Control valves are fixedly installed on the surfaces of both the drain pipe 23 and the water inlet pipe 24. Connecting flanges 2 are fixedly installed at the inlet ends of both the drain pipe 23 and the water inlet pipe 24. 5. The centrifugal rotating assembly includes a mounting bracket 2 fixedly installed on the top of the filter box 1. A drive motor 3 is fixedly installed at the bottom of the mounting bracket 2. A coupling is fixedly installed at the output end of the drive motor 3. A rotating shaft 4 is installed at the output end of the drive motor 3 through the coupling. The rotating shaft 4 is rotatably located inside the filter box 1. A rotating disk 5 is fixedly installed on the top of the rotating shaft 4. The rotating disk 5 is located inside the filter box 1. Both the outer filter screen 6 and the inner filter screen 7 are fixedly installed on the top of the rotating disk 5. The scraper-type inlet and outlet assembly includes a mounting sleeve 8 fixedly installed inside the cover plate. A mounting ring 9 is fixedly installed on the outer surface of the mounting sleeve 8. A fixing plate 10 is fixedly installed on the outer surface of the mounting ring 9. An outer scraper 11 is fixedly installed at the bottom of the fixing plate 10. There are two inner scrapers 12, two outer scrapers 11, and two inner scrapers 12, and the two outer scrapers 11 and the two inner scrapers 12 are symmetrically distributed. The outer scrapers 11 are in contact with the outer filter screen 6, and the inner scrapers 12 are in contact with the inner filter screen 7. An inlet and outlet pipe 13 is fixedly installed inside the mounting sleeve 8. A three-way pipe 14 is fixedly installed at the liquid inlet end of the inlet and outlet pipe 13. An inlet pipe 15 and a outlet pipe 16 are fixedly installed inside the three-way pipe 14. Control valves are fixedly installed on the surface of the inlet pipe 15 and the surface of the outlet pipe 16. When the control valve on the inlet pipe 15 is opened, the concentrated slurry is transported through the inlet pipe 15 to the three-way pipe 14, and then enters the inner filter screen 7 through the inlet and outlet pipes 13. Then, the drive motor 3 drives the coupling to rotate the rotating shaft 4. The rotating disc 5 drives the outer filter screen 6 and inner filter screen 7 to perform multi-stage filtration of the concentrated slurry. During the rotation of the outer filter screen 6 and inner filter screen 7, the outer scraper 11 and inner scraper 12 scrape the impurities attached to the inside of the outer filter screen 6 and inner filter screen 7, and water is transported to the inside of the filter box 1 through the water inlet pipe 24, so that the water flows to wash the outer filter screen 6 and inner filter screen 7. The water carries the impurities into the three-way pipe 14 through the inlet and outlet pipe 13, and is discharged into the external collection device through the outlet pipe 16. This makes the inner filter screen 7 and outer filter screen 6 cleaner, avoiding the situation where dead corners are easily missed by manual scraping, and avoiding the situation where fine particles may be embedded deep in the filter holes due to simple backflushing cleaning.

[0022] Specifically, the inner filter screen 7 has a support assembly on its surface. The support assembly includes a mounting plate 17 fixedly installed on the surface of the inner filter screen 7. The bottom of the mounting plate 17 has a mounting groove 18. A number of balls 19 are overlapped inside the mounting groove 18 and are arranged in a circular array. The balls 19 are made of stainless steel. A limiting plate 20 is fixedly installed at the bottom of the mounting groove 18. A limiting groove 21 is provided through the top of the limiting plate 20. The inner wall of the limiting groove 21 overlaps with the surface of the balls 19. A support plate 22 is overlapped at the bottom of the balls 19. The support plate 22 is fixedly installed inside the filter box 1. When the inner filter screen 7 rotates, it will drive the mounting plate 17 to rotate. Through the movement of the balls 19 on the mounting plate 17 and the limiting groove 21, the balls 19 roll on the surface of the support plate 22, thereby assisting in the formation of the inner filter screen 7, making the rotation of the inner filter screen 7 more stable, making the rotation of the rotating disk 5 more stable, and thus making the rotation of the outer filter screen 6 more stable.

[0023] In use: When filtering concentrated beverage slurry, open the control valve on the inlet pipe 15. The concentrated slurry is then transported into the inlet pipe 15 via an external conveying device, and enters the inlet / outlet pipe 13 through the three-way pipe 14. It then enters the inner filter screen 7 through the inlet / outlet pipe 13. The drive motor 3 drives the coupling to rotate the rotating shaft 4, which in turn rotates the rotating disk 5. The rotating disk 5 then rotates the outer filter screen 6 and the inner filter screen 7. This causes the concentrated slurry in the inner filter screen 7 to enter the outer filter screen 6 due to centrifugal force, while the concentrated slurry in the outer filter screen 6 is removed from it due to centrifugal force and discharged through the drain pipe 23 to the external collection device. This process performs multi-stage filtration of the concentrated slurry. Furthermore, during the rotation of the outer filter screen 6 and the inner filter screen 7, the concentrated slurry is further filtered... The filter screen 7 moves relative to the outer scraper 11 and the inner scraper 12. The outer scraper 11 and the inner scraper 12 scrape away the impurities attached to the outer filter screen 6 and the inner filter screen 7, preventing the impurities from adhering to the mesh of the outer filter screen 6 and the inner filter screen 7. Moreover, it is connected to the external water flow conveying equipment through the connecting flange 25 on the water inlet pipe 24. The water flow is delivered to the inside of the water inlet pipe 24 through the water inlet pipe 24 and enters the filter box 1, so that the water flow washes the outer filter screen 6 and the inner filter screen 7. The water flow carries the impurities washed off and the impurities scraped off by the outer scraper 11 and the inner scraper 12 into the inlet and outlet pipe 13, and then into the three-way pipe 14 through the inlet and outlet pipe 13, and then into the outlet pipe 16 through the three-way pipe 14, and finally discharged into the external collection device through the outlet pipe 16.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
