[0002] Juice is a liquid product obtained from fruit through physical methods such as squeezing, centrifugation, and extraction. It generally refers to pure juice or 100% fruit juice. Juice is categorized by form into clear juice and cloudy juice. Clarified juice, such as apple juice, is transparent, while cloudy juice, such as orange juice, is uniformly turbid. Based on the juice content, juice can be categorized as original juice, fruit juice, juice beverages, fruit juice beverages, juice sodas, and fruit-flavored beverages. During juice production, filtration is required to separate the juice from the fruit pulp, resulting in a purer juice.

[0020] The utility model provides Figures 1 to 3The filtering device for juice shown in the figure includes a liquid collecting tank 1, a circular groove 3 is opened through the top of the liquid collecting tank 1, a filter barrel 2 is fixedly connected to the upper surface of the top of the liquid collecting tank 1, and the filter barrel 2 is connected to the liquid collecting tank 1 through the circular groove 3. The bottom end of the liquid collecting tank 1 is connected to a liquid outlet pipe 16, and an electric control valve is installed on the liquid outlet pipe 16.

[0021] The interior of the filter barrel 2 is provided with a rigid sleeve 7, which is connected to the circular groove 3. The inner diameter of the rigid sleeve 7 is consistent with the inner diameter of the circular groove 3, and the height of the rigid sleeve 7 is suitable for accumulating fruit pulp. The top of the rigid sleeve 7 is connected to the filter bag 8. A slide 17 is slidingly provided inside the filter barrel 2. The top of the filter bag 8 is fixedly connected to the slide 17. The filter screen 4 is fixedly connected to the interior of the circular groove 3. The slide 17 is provided with a circular hole, and an injection tube 13 is fixedly connected to the inside of the circular hole. The injection tube 13 is arranged in a corresponding position with the filter bag 8. The end of the injection tube 13 away from the slide 17 extends to the outside of the filter barrel 2. The injection tube 13 is connected to the juice delivery pipeline, so that the juice can be injected into the filter bag 8 through the injection tube 13. The injection tube 13 is a telescopic hose and does not affect the upward and downward movement of the slide 17.

[0022] A first solenoid valve 14 is fixedly mounted on the liquid injection pipe 13 .

[0023] A liquid cavity 5 is formed between the filter bag 8 and the inner wall of the filter barrel 2 . A through liquid hole 6 is provided on the top of the liquid collecting tank 1 . A plurality of liquid holes 6 are provided. The liquid cavity 5 is connected to the liquid collecting tank 1 through the liquid holes 6 .

[0024] The top of the filter barrel 2 is fixedly connected to an electric push rod 12 . A round hole is opened on the top of the filter barrel 2 for the telescopic end of the electric push rod 12 to pass through. The slide plate 17 is fixedly connected to the telescopic end of the electric push rod 12 .

[0025] During actual use, the first solenoid valve 14 is opened, and juice is injected into the filter bag 8 through the liquid injection tube 13. The first solenoid valve 14 is then closed. The telescopic end of the electric push rod 12 is controlled to extend, driving the slide plate 17 to move downward to compress the filter bag 8, thereby quickly squeezing out the juice in the filter bag 8. Some of the juice flows through the filter bag 8 into the liquid cavity 5 and then into the liquid collection tank 1 through the liquid hole 6; another part of the juice passes through the filter screen 4 and directly flows into the liquid collection tank 1.

[0026] The juice can be discharged from the liquid outlet pipe 16.

[0027] Taking into account that the filter screen 4 is prone to clogging, a through groove is opened on the filter screen 4, and a threaded barrel 9 is rotatably connected inside the through groove. A scraper 10 is fixedly connected to the outer wall of the threaded barrel 9. The scraper 10 is attached to the upper surface of the filter screen 4, and a threaded rod 11 is fixedly connected to the lower surface of the slide plate 17. The threaded rod 11 is threadedly matched with the threaded barrel 9, and a relatively smooth internal thread and external thread structure can be set between the threaded rod 11 and the threaded barrel 9.

[0028] Specifically, when the electric push rod 12 drives the slide plate 17 to move downward to compress the filter bag 8, it will drive the threaded rod 11 to move linearly downward. Since the threaded rod 11 and the threaded barrel 9 are threadedly matched, the threaded barrel 9 rotates, and the threaded barrel 9 drives the scraper 10 to push and scrape the pulp accumulated on the upper surface of the filter screen 4, thereby improving the filtration efficiency.

[0029] By providing structures such as the threaded rod 11, the threaded barrel 9 and the scraper 10, during the compression of the filter bag 8, the threaded barrel 9 drives the scraper 10 to push and scrape the pulp accumulated on the surface of the filter screen 4, thereby achieving high filtration efficiency and improving the utilization efficiency of the filtering device.

[0030] In addition, a cleaning door and door panel (not shown in the figure) can be provided on the filter barrel 2, and the filter bag 8, filter screen 4, etc. can be cleaned through the cleaning door.

[0031] To prevent the filtered juice from settling inside the liquid collecting tank 1, a stirring blade 15 is fixedly connected to the outer wall of the threaded barrel 9. When the threaded barrel 9 rotates, the stirring blade 15 is driven to stir the juice in the liquid collecting tank 1 to avoid precipitation.
