Description

Technical Field

[0001] This utility model relates to a tomato filtration device, belonging to the field of tomato processing technology. Background Technology

[0002] Tomato sauce is a thick liquid obtained by scalding, peeling, crushing, and filtering tomatoes. It is rich in lycopene, vitamin C, organic acids, and minerals, has antioxidant properties, and helps promote the absorption of calcium and iron as well as protein digestion, making it very popular.

[0003] In existing technology, peeled tomatoes are usually put into a juicer and crushed into tomato paste. The tomato paste is then put into a gauze bag for filtering. To speed up the filtering process, a squeezer is usually used to squeeze the gauze bag to squeeze out the pulp from the tomato paste. The resulting pulp is tomato sauce, while impurities remain in the gauze bag.

[0004] Extrusion machines come in all shapes and sizes, each with its own advantages and disadvantages. Utility Model Content

[0019] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Specific embodiments of the tomato filtration device involved in this utility model are as follows: Figures 1-8The device includes a frame 1 for supporting various components. An outer cylinder 2 is fixedly mounted on the frame 1. One end of the outer cylinder 2 has a sealing plate 3. An outer scraper 4 is installed inside the outer cylinder 2. The outer scraper 4 has a support portion, and a rotating shaft 6 is fixed to one side of the support portion. The outer scraper 4 is rotatably mounted on the sealing plate 3 via the rotating shaft 6. The sealing plate 3 has a through hole, through which the rotating shaft 6 passes and extends out of the sealing plate 3. The rotating shaft 6 can rotate in a sealed manner within the through hole, and can be rotated by external force from the outside of the outer cylinder 2. The rotating shaft 6 can rotate the outer scraper 4 together, thus allowing the outer scraper 4 to rotate within the outer cylinder 2. Freely suspended scraper blades 7 are arranged on the outer edge of the support section. These scraper blades 7 are evenly spaced on the cylindrical surface and form a cylindrical cavity within the outer scraper 4. When the outer scraper 4 rotates within the outer cylinder 2, the scraper blades 7 on the support section rotate with it. During rotation, the scraper blades 7 can scrape any objects they come into contact with. The spacing between the scraper blades 7 allows the object to be scraped to hang down, making it easier to scrape the object when the scraper blades 7 rotate with the outer scraper 4. A movable sealing plate 8 is provided at the other end of the outer cylinder 2. The movable sealing plate 8 is slidably mounted on the frame 1 using a linear drive mechanism. The movable sealing plate 8 can slide back and forth in the direction of the outer cylinder 2 and away from it. A support frame 9 is fixed to the movable sealing plate 8. The support frame 9 is a columnar frame, with one end fixed to the movable sealing plate 8 via a mounting part. The outer diameter of 9 is smaller than the inner diameter of the outer scraper 4. After the movable sealing plate 8 moves outward away from the outer cylinder 2, the support frame 9 can move outside the outer cylinder 2. There is a detachable fixing part between the outer cylinder 2 and the movable sealing plate 8 that can press and fix the two together. After the movable sealing plate 8 is engaged with the outer cylinder 2, the support frame 9 is inserted into the cylindrical cavity of the outer scraper 4. The support frame 9 is inserted into the outer scraper 4 with a gap. At this time, the outer scraper 4 and the support frame 9 are both inside the outer cylinder 2, and the support frame 9 does not interfere with the rotation of the outer scraper 4.

[0021] Before use, a separately equipped motor (not shown in the figure) is needed to drive the rotating shaft 6 to rotate. The motor housing is fixed to the frame 1 on the side of the sealing plate 3 away from the outer cylinder 2, and the rotating shaft of the motor is fixed to the rotating shaft 6. In use, first use the linear drive mechanism to drive the moving sealing plate 8 to slide the moving sealing plate 8 to the outside of the outer cylinder 2, so that the moving sealing plate 8 slides with the support frame 9, thereby moving the support frame 9 outside the outer cylinder 2. Then, put the gauze bag containing tomato paste on the outside of the support frame 9, and tie the mouth of the gauze bag tightly on the mounting part of the support frame 9, thereby fixing the gauze bag on the support frame 9. Then, use the linear drive mechanism to slide the moving sealing plate 8 towards the outer cylinder 2, so that the moving sealing plate 8 slides to the outer cylinder 2. The opening end is opened so that the gauze bag containing tomato paste and the support frame 9 are inserted into the outer cylinder 2 together. Then, the movable sealing plate 8 is pressed and fixed on the outer cylinder 2 with a detachable fastener. The gauze bag containing tomato paste is located between the support frame 9 and the outer scraper 4. Under the action of gravity, the part of the gauze bag stacked on the outer scraper 7 with the gauze bag at the bottom hangs down from the gap between the scraper 7 to below the scraper 7. Then, the motor is started to drive the rotating shaft 6 to rotate, thereby rotating the outer scraper 4 together. When the outer scraper 4 rotates, the scraper 7 on the outer scraper 4 continuously scrapes the gauze bag, thereby squeezing out the pulp in the tomato paste in the gauze bag. The resulting pulp is tomato sauce. The squeezed tomato sauce flows into the outer cylinder 2 and is collected by the outer cylinder 2.

[0022] Specifically, one end of the support frame 9 has a support circular plate 11, and the outer edge of the support circular plate 11 is provided with freely extending support plates 12. The support plates 12 can both support the gauze bag containing tomato paste, preventing most of the gauze bag from drooping on the outer scraper 4 and interfering with the scraping operation of the outer scraper 4, and allow the tomato paste in the gauze bag to flow into the drooping end of the gauze bag through the gaps between the support plates 12. When the detachable fastener presses and fixes the movable sealing plate 8 to the outer cylinder 2, the movable sealing plate 8 cooperates with the outer cylinder 2, and the support plates 12 are interposed in the gaps between the scrapers 7 on the outer scraper 4, and each support plate 12 is located in the cylindrical cavity enclosed by the outer scraper 4.

[0023] Specifically, the support plate 12 is a strip plate formed by opening U-shaped grooves on the cylindrical surface.

[0024] Specifically, the mounting part is a mounting shaft 10, which is fixed in the mounting hole provided on the movable sealing plate 8 by means of forced installation. The mounting shaft 10 and the movable sealing plate 8 are anti-rotationally engaged. An annular groove 16 is provided on the outer periphery of the mounting shaft 10 outside the mounting hole. When the gauze bag containing tomato paste is fixed on the support frame 9, the opening of the gauze bag, which is sleeved on the support frame 9, is tied tightly in the annular groove 16, which can make the gauze bag more secure and prevent the tomato paste from overflowing from the opening of the gauze bag and contaminating the squeezed tomato sauce.

[0025] Specifically, the mounting hole is the inner hole of the fixing cylinder 13 on the movable sealing plate 8.

[0026] Specifically, the support includes a retaining ring 14 on its outer edge, and spokes 15 are connected between the inside of the retaining ring 14 and the rotating shaft 6. The spokes 15 make the support hollow, which on the one hand allows it to scrape the objects it touches during rotation; on the other hand, it reduces the weight of the support and saves costs.

[0027] Specifically, scraper 7 is a strip-shaped plate formed by opening U-shaped grooves on the surface of a cylinder.

[0028] Specifically, the detachable fasteners include bolt rods 17 rotatably mounted on the outer circumference of the outer cylinder 2, and U-shaped notches 18 arranged on the outer circumference of the movable sealing plate 8. The bolt rods 17 can be rotated into the U-shaped notches 18 one by one, and nuts 19 that press the movable sealing plate 8 are screwed onto the bolt rods 17.

[0029] Specifically, the linear drive mechanism is a pneumatic cylinder 20, the cylinder body of which is fixed on the frame 1, and the piston rod of which is fixed on the movable sealing plate 8.

[0030] Specifically, a guide cylinder 21 is provided on the frame 1. The guide cylinder 21 is fixed on the frame 1. The piston rod of the pneumatic cylinder 20 slides through the guide cylinder 21 and is fixed to the movable sealing plate 8.

In other embodiments, the mounting part can also be a square protrusion, and a square groove that mates with the square protrusion is provided on the movable sealing plate. The square protrusion is fixed in the square groove by a forced mounting method.

[0034] In the above embodiment, the support includes a fixing ring on the outer edge, and spokes are connected between the inside of the fixing ring and the rotating shaft. This is an optimized technical solution. In other embodiments, the fixing ring and spokes can be replaced as a whole with a circular filter screen.

[0035] In the above embodiments, the scraper is a strip-shaped plate formed by opening a U-shaped groove on the cylindrical surface. This is an optimized technical solution. In other embodiments, the scraper can also be a long plate with a fixed ring set on the side of the support away from the rotating shaft.

[0036] In the above embodiments, the detachable fastener includes a bolt rod rotatably mounted on the outer circumferential surface of the outer cylinder, and a U-shaped notch is provided on the outer circumference of the movable sealing plate. The bolt rod can be rotated into the U-shaped notch one by one, and a nut for pressing the movable sealing plate is screwed on the thread of the bolt rod. In other embodiments, the detachable fastener may also be a hook hinged to the outer circumferential surface of the outer cylinder and a buckle fixedly mounted on the outer circumference of the movable sealing plate and corresponding to the hook.

[0037] In the above embodiments, the linear drive mechanism is a pneumatic cylinder. In other embodiments, the pneumatic cylinder can be replaced with a hydraulic cylinder.
