Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for wild tea beer residue and yeast. Background Technology

[0002] In the production process of wild tea beer, the separation and filtration of tea residue and yeast is a crucial step. Traditional filtration methods typically use a single filter screen, which is insufficient to simultaneously meet the requirements of thoroughly filtering tea residue, retaining a certain proportion of yeast, and fully recovering tea juice from the tea residue. If relying solely on the filter screen, the tea residue easily clogs the screen, resulting in low filtration efficiency and an inability to accurately control the amount of yeast retained. On the other hand, existing filtration devices often overlook the large amount of tea juice remaining in the tea residue when processing it. This tea juice is rich in effective components such as tea polyphenols and amino acids. Directly discarding it not only wastes raw materials but also increases production costs. Therefore, this utility model proposes a wild tea beer tea residue and yeast filtration device to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, such as tea residue clogging the filter, tea juice waste, and inaccurate yeast retention, this invention incorporates a servo motor-driven cleaning component, elastic pressure rollers, and a disc centrifuge. This achieves automatic tea residue cleaning, efficient tea juice recovery, and precise yeast retention, avoiding the inefficiency of manual cleaning and material waste, and significantly improving the filtration efficiency and quality of wild tea beer.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wild tea brewing residue and yeast filtration device, comprising a filter box and a disc centrifuge, wherein the disc centrifuge is installed at the lower end of the filter box and the filter box and the disc centrifuge are interconnected, a feed hopper is fixedly connected to the upper end of the filter box, a bottom plate is fixedly connected to the inner wall of the filter box and the end face of the bottom plate is covered with filter cloth, multiple sets of through holes are opened through the outer wall of the bottom plate, a positioning plate is slidably connected inside the filter box, two sets of pressure rollers and a single set of scrapers are installed on the outer wall of the positioning plate, a driving mechanism is installed inside the filter box, and an elastic mechanism is installed on the outer wall of the positioning plate; The driving mechanism is used to drive the positioning plate and its external components to slide on the end face of the filter cloth. The elastic mechanism is used to drive the pressure roller and scraper to fit tightly against the end face of the filter cloth.

[0005] Preferably, the driving mechanism includes a threaded rod rotatably connected inside the filter box, a movable block being threadedly connected to the threaded section of the threaded rod, and a positioning plate being fixedly connected to the side wall of the movable block.

[0006] Preferably, a limiting rod is fixedly connected to the inner wall of the filter box, a slider is slidably connected to the outer wall of the limiting rod, and a liquid guide plate is fixedly connected to the upper end of both the threaded rod and the limiting rod, with the liquid guide plate covering the outer wall of the threaded rod and the limiting rod.

[0007] Preferably, the elastic mechanism includes two sets of connecting rods slidably connected to the end face of the positioning plate. The outer walls of the two sets of connecting rods are slidably connected to a slide plate. The outer walls of the slide plates are fixedly connected to two sets of connecting plates, and their ends are respectively fixedly connected to two sets of pressure rollers. The outer walls of the connecting rods are fitted with springs, and the two ends of the springs are respectively fixedly connected to the end face of the positioning plate and the bottom of the slide plate.

[0008] Preferably, a sliding rod is fixedly connected to the lower end of the slide plate, the sliding rod is slidably connected to the positioning plate, and the end of the sliding rod is fixedly connected to the end face of the scraper. The scraper is located between two sets of pressure rollers, and a limit block is fixedly connected to the end face of the connecting rod, and the radius of the limit block is larger than the radius of the connecting rod.

[0009] Preferably, two sets of waste boxes are slidably connected to the inner wall of the filter box and extend to the outside of the filter box. The end faces of the two sets of waste boxes are horizontal with the end faces of the filter cloth. A servo motor is fixedly connected to the outer wall of the filter box, and the output shaft is coaxially fixedly connected to the threaded rod.

[0010] Compared with the prior art, this utility model provides a wild tea brewing residue and yeast filtration device, which has the following beneficial effects: A servo motor drives a threaded rod to rotate, causing the positioning plate, pressure roller, and scraper to slide continuously on the filter cloth surface. The pressure roller compacts the tea residue and squeezes out residual tea juice, which is then collected together with the filtered liquid through the bottom plate's through-hole. At the same time, the scraper scrapes off the tea residue in time and collects it into the waste box, preventing the tea residue from accumulating and clogging the filter cloth, eliminating the need for manual cleaning by stopping the machine. In addition, a disc centrifuge is used to centrifuge and separate the filtered liquid, accurately retaining about 1% of the yeast. Compared with the traditional single-filter filtration method, this method not only solves the problems of tea juice waste and tea residue clogging, but also overcomes the shortcomings of the difficulty in accurately controlling yeast, effectively improving filtration efficiency, reducing labor intensity, and improving raw material utilization and the brewing quality of wild tea beer.

[0013] This utility model provides a technical solution for a wild tea brewing residue and yeast filtration device: Please see Figure 1-4 A filtering device for wild tea beer residue and yeast includes a filter box 1 and a disc centrifuge 2. The disc centrifuge 2 is installed at the lower end of the filter box 1 and the filter box 1 and the disc centrifuge 2 are interconnected. A feed hopper 3 is fixedly connected to the upper end of the filter box 1. A bottom plate 10 is fixedly connected to the inner wall of the filter box 1, and the end face of the bottom plate 10 is covered with a filter cloth 7. Multiple sets of through holes are opened through the outer wall of the bottom plate 10. A positioning plate 13 is slidably connected inside the filter box 1. Two sets of pressure rollers 14 and a single set of scrapers 15 are installed on the outer wall of the positioning plate 13. A driving mechanism is installed inside the filter box 1, and an elastic mechanism is installed on the outer wall of the positioning plate 13. The drive mechanism is used to drive the positioning plate 13 and its external components to slide on the end face of the filter cloth 7; The elastic mechanism is used to drive the pressure roller 14 and scraper 15 to fit tightly against the end face of the filter cloth 7; Furthermore, by combining the filter cloth 7 with the disc centrifuge 2, compared with traditional single-screen filtration, it can effectively filter tea residue and accurately retain about 1% of yeast using the disc centrifuge 2; at the same time, the positioning plate 13, pressure roller 14 and scraper 15 can clean and compact the tea residue on the filter cloth 7 and squeeze out the residual tea juice in the tea residue.

[0014] The drive mechanism includes a threaded rod 8 rotatably connected inside the filter box 1, a movable block 12 threadedly connected to the threaded section of the threaded rod 8, and a positioning plate 13 fixedly connected to the side wall of the movable block 12. Furthermore, the threaded engagement between the threaded rod 8 and the moving block 12 allows for precise control of the movement of the positioning plate 13, thereby driving the pressure roller 14 and scraper 15 to slide stably on the surface of the filter cloth 7, continuously cleaning the tea residue on the filter cloth 7 and preventing the tea residue from clogging the filter cloth 7.

[0015] A limiting rod 9 is fixedly connected to the inner wall of the filter box 1. A slider 11 is slidably connected to the outer wall of the limiting rod 9. A liquid guide plate 5 is fixedly connected to the upper end of both the threaded rod 8 and the limiting rod 9. The liquid guide plate 5 covers the outer wall of the threaded rod 8 and the limiting rod 9. Furthermore, the setting of the limiting rod 9 and the slider 11 can effectively prevent the positioning plate 13 from shifting during movement, ensuring that the pressure roller 14 and scraper 15 can stably clean the filter cloth 7; while the liquid guide plate 5 can guide the liquid through, avoiding the liquid from contacting the outer wall of the threaded rod 8 and the limiting rod 9, thus affecting the transmission of the threaded rod 8 and the limiting rod 9.

[0016] The elastic mechanism includes two sets of connecting rods 16 slidably connected to the end face of the positioning plate 13. The outer walls of the two sets of connecting rods 16 are slidably connected to slide plates. The outer walls of the slide plates are fixedly connected to two sets of connecting plates 19, and their ends are fixedly connected to two sets of pressure rollers 14 respectively. The outer walls of the connecting rods 16 are fitted with springs 18, and the two ends of the springs 18 are fixedly connected to the end face of the positioning plate 13 and the bottom of the slide plate respectively. Furthermore, the elastic force of the spring 18 ensures that the pressure roller 14 always fits tightly against the filter cloth 7, which can fully squeeze out the tea juice from the tea residue during the process of compacting the tea residue, thereby improving the tea juice recovery rate.

[0017] A slide rod 20 is fixedly connected to the lower end of the slide plate. The slide rod 20 is slidably connected to the positioning plate 13, and the end of the slide rod 20 is fixedly connected to the end face of the scraper 15. The scraper 15 is located between two sets of pressure rollers 14. A limit block 17 is fixedly connected to the end face of the connecting rod 16, and the radius of the limit block 17 is larger than the radius of the connecting rod 16. Furthermore, the slide bar 20 enables the scraper 15 to move up and down with the slide plate, always maintaining a good fit with the filter cloth 7, effectively scraping off and collecting the tea residue after it has been compacted by the pressure roller 14.

[0018] Two sets of waste boxes 6 are slidably connected to the inner wall of the filter box 1 and extend to the outside of the filter box 1. The end faces of the two sets of waste boxes 6 are horizontal with the end faces of the filter cloth 7. A servo motor 4 is fixedly connected to the outer wall of the filter box 1, and the output shaft is coaxially fixedly connected to the threaded rod 8. Furthermore, the waste box 6 adopts a sliding connection and is flush with the filter cloth 7, so that the tea residue scraped off by the scraper 15 can slide smoothly into the waste box 6, and the waste box 6 can be pulled out directly when cleaning.

[0019] When the operator starts the wild tea beer tea residue and yeast filtration device, the wild tea beer mixture flows into the filter box 1 through the feed hopper 3. At this time, the filter cloth 7 covers the bottom plate 10, and the mixture begins to be initially filtered. The tea residue is intercepted on the surface of the filter cloth 7, while the liquid containing yeast flows downward through the through holes on the bottom plate 10 and enters the disc centrifuge 2 for the next step of separation.

[0020] During the filtration process, the servo motor 4 drives the threaded rod 8 to rotate, causing the threaded moving block 12 to move smoothly along the threaded rod 8, thereby allowing the positioning plate 13, fixed to the side wall of the moving block 12, to slide on the surface of the filter cloth 7. At this time, the limiting rod 9 cooperates with the slider 11 to ensure that the positioning plate 13 does not shift, making the movement process more stable. At the same time, the liquid guiding plate 5 guides the liquid to the surrounding area, preventing the liquid from flowing onto the threaded rod 8 and the limiting rod 9, thus preventing interference with the transmission.

[0021] As the positioning plate 13 slides, the elastic force of the spring 18 pushes the sliding plate, causing the pressure roller 14 to press tightly against the filter cloth 7, compacting the tea residue on the surface of the filter cloth 7. During the compaction process, the residual tea juice in the tea residue is fully squeezed out and flows away with the filtered liquid through the through holes of the filter cloth 7 and the bottom plate 10, improving the tea juice recovery rate. The scraper 15, located between the two sets of pressure rollers 14, is connected to the sliding plate through the slide rod 20 and can move up and down with the sliding plate, always keeping in contact with the filter cloth 7 to scrape off the tea residue compacted by the pressure rollers 14.

[0022] The scraped tea leaves slide down the filter cloth 7 into the waste box 6 located on the inner wall of the filter chamber 1. The waste box 6 is flush with the filter cloth 7 and is connected by a sliding mechanism, allowing it to be easily pulled out for cleaning. Subsequently, the disc centrifuge 2 centrifuges the filtered liquid, precisely retaining approximately 1% of the yeast. In this way, the device achieves efficient filtration and cleaning of tea leaves, fully recovers the tea juice, and precisely retains the yeast, avoiding problems such as tea leaf clogging, tea juice waste, and inaccurate bacterial retention in traditional filtration methods, making the filtration process for wild tea beer more efficient and convenient.

[0023] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
