Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a rapid solid-liquid separation device for food processing. Background Technology

[0002] Solid-liquid separation is a fundamental and crucial process in food processing, agricultural product processing, and environmental protection. Traditional solid-liquid separation methods mainly rely on natural drainage, gravity sedimentation, or manual pressing. These methods generally suffer from low separation efficiency, high labor intensity, and difficulty in controlling hygiene conditions. For example, in fruit and vegetable juice processing, manual pressing is not only time-consuming and labor-intensive but also results in inconsistent juice yield; in soy product production, traditional drainage methods are insufficient to fully extract protein solutions, leading to resource waste.

[0003] While existing mechanical solid-liquid separation equipment has improved production efficiency to some extent, it still faces numerous technical bottlenecks. Common screw presses and centrifugal separators often suffer from drawbacks such as large size, high energy consumption, and poor adaptability to materials. Particularly for materials with high viscosity or high fiber content, incomplete separation and high residual liquid rates are common. Furthermore, most equipment lacks an adjustable extrusion mechanism, failing to flexibly adjust pressure according to the characteristics of different materials, resulting in unsatisfactory solid-liquid separation effects. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid solid-liquid separation device for food processing. This device can flexibly adjust pressure parameters according to the characteristics of different materials while ensuring separation effect, thereby reducing material loss and maintenance costs and meeting the modern food processing industry's demand for high-efficiency and energy-saving production.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A rapid solid-liquid separation device for food processing includes a solid-liquid separation chamber having an inlet, a solid discharge outlet, and a liquid discharge outlet; a conveyor belt made of a water-permeable material, installed inside the solid-liquid separation chamber; a first pressure rod rotatably connected to the inner wall of the solid-liquid separation chamber and located below the conveyor belt; a second pressure rod vertically slidably connected to the inner wall of the solid-liquid separation chamber and located above the conveyor belt; and a lifting structure disposed inside the solid-liquid separation chamber, which drives the second pressure rod to move closer to the first pressure rod to adjust the distance between the first and second pressure rods and to compress the material flowing on the conveyor belt below the second pressure rod.

[0007] Preferably, the lifting structure includes: vertically formed sliding grooves on opposite side walls of the solid-liquid separation tank, with the second pressure rod slidingly engaged with the sliding grooves; a threaded rod, which is horizontally rotatably connected to the inner wall of the solid-liquid separation tank; a nut seat, which is threadedly engaged with the threaded rod; and a connecting rod, the top end of which is hinged to the nut seat, and the bottom end of which is hinged to the second pressure rod.

[0008] Preferably, a handwheel for driving the threaded rod to rotate is installed on the side of the solid-liquid separation tank.

[0009] Preferably, the solid-liquid separation tank is equipped with a limiting component for adjusting the feed rate. The limiting component includes: a vertical groove formed inside the solid-liquid separation tank, with a threaded hole at the top of the vertical groove; a baffle that can move up and down in the vertical groove; and a fastening bolt inserted into the threaded hole, with the bottom end of the fastening bolt rotatably connected to the baffle.

[0010] Preferably, a scraper assembly is installed in the solid-liquid separation tank. The scraper assembly includes: a scraper, one end of which is connected to the inner wall of the solid-liquid separation tank via a connecting shaft; and an electric telescopic rod, one end of which is hinged to the inner wall of the solid-liquid separation tank, and the other end of which is hinged to the middle of the scraper.

[0011] Preferably, the solid discharge port is located below the scraper, and the scraper has a through groove for discharging the scraped solid material through the through groove to the solid discharge port.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the device significantly improves the efficiency and quality of solid-liquid separation by combining mechanical extrusion with filtration and transmission. Compared with traditional manual operation, the water-permeable conveyor belt and double-pressure bar extrusion structure can fully extract residual liquid from the solid, thereby increasing the yield. The distance between the two pressure bars can be adjusted by handwheel to adapt to the extrusion requirements of different materials. The baffle can control the feed thickness to ensure uniform extrusion. The electric scraper automatically cleans the adhering materials, reducing manual intervention and labor intensity.

[0017] Example 1

[0018] like Figure 1 and Figure 2As shown, a rapid solid-liquid separation device for food processing is provided, which mechanically replaces manual solid-liquid separation operations. To fully extract the liquid from the solid, the device is designed with a squeezing structure to compress the solid material during transport, achieving simultaneous solid-liquid separation. This solid-liquid separation structure includes the following components: a solid-liquid separation tank 1, a conveyor belt 5, a first pressure bar 6, a second pressure bar 7, and a lifting structure. The solid-liquid separation tank 1 has a feed inlet 2, a solid discharge outlet 3, and a liquid discharge outlet 4. Raw materials enter through the feed inlet 2 and then fall onto the conveyor belt 5, which is installed inside the solid-liquid separation tank 1. The conveyor belt 5 adopts a [missing information - likely a specific design or feature]. A conveyor belt 5 with solid-liquid filtration function is used. Solids in the raw material are retained on the surface of the conveyor belt 5 and fall off at the end of the conveyor belt 5, collecting in the solid discharge port 3 below. Liquids pass through the conveyor belt 5 and collect in the liquid discharge port 4 below. The solid extrusion is completed by two pressure rods (first pressure rod 6 and second pressure rod 7). The first pressure rod 6 is rotatably connected to the inner wall of the solid-liquid separation tank 1 and is located below the conveyor belt 5. The second pressure rod 7 is vertically slidably connected to the inner wall of the solid-liquid separation tank 1 and is located above the conveyor belt 5. The lifting structure uses the solid-liquid separation tank 1 as support and drives the second pressure rod 7 to move closer to the first pressure rod 6. To adjust the distance between the first pressure rod 6 and the second pressure rod 7, and to compress the material flowing on the conveyor belt 5 to the side below the second pressure rod 7, the lifting structure includes a chute 8, a threaded rod 9, a nut seat 10, a connecting rod 11, and a handwheel 12. The connections of each component are as follows: The solid-liquid separation tank 1 has vertically opened chute 8 on opposite side walls, allowing the end of the second pressure rod 7 to slide vertically. The threaded rod 9 is horizontally arranged in the solid-liquid separation tank 1, with both ends of the threaded rod 9 connected to the inner wall of the solid-liquid separation tank 1 via bearing seats. The threaded rod 9 passes through the nut seat 10, and the nut seat 10 is threadedly connected to the threaded rod 9. The top end of the connecting rod 11 is connected to the nut seat 12. The seat 10 is hinged, and the bottom end of the connecting rod 11 is hinged to the second pressure rod 7. The end of the threaded rod 9 that protrudes from the solid-liquid separation box 1 is fixedly connected to a handwheel 12. Rotating the handwheel 12 can adjust the distance between the two, thereby further extracting liquid from the solid and achieving solid-liquid separation. In use, rotating the handwheel 12 drives the threaded rod 9 to rotate, causing the nut seat 10 to move along the central axis of the threaded rod 9. The connecting rod 11 pulls the second pressure rod 7 up and down in the slide groove 8, changing the distance between the first pressure rod 6 and the second pressure rod 7. By adjusting this distance, water can be extracted from solids of different sizes, and solid-liquid separation can be achieved.

[0019] like Figure 2As can be seen, in order to adjust the thickness of solid residue on the conveyor belt 5 and prevent a large amount of solid material to be processed from flowing into the extrusion structure, a limiting component is designed to control the feed rate. This limiting component includes a vertical groove 13 inside the solid-liquid separation box 1, with a threaded hole 14 at the top of the vertical groove 13; a baffle 15 that can move up and down is provided in the vertical groove 13; and a fastening bolt 16, which is screwed into the threaded hole 14. The bottom end of the fastening bolt 16 is rotatably connected to the baffle 15. By tightening the fastening bolt 16, the fastening bolt 16 moves up and down in the threaded hole 14, causing the baffle 15 to move up and down in the vertical groove 13, thereby changing the distance between the baffle 15 and the conveyor belt 5. As the distance between the two shortens, the thickness of the solid material entering the gap between the two pressure bars decreases, allowing the two pressure bars to carry out the extrusion operation more fully.

[0020] like Figure 2 As shown, the extruded material adheres to the conveyor belt 5 and cannot fall smoothly to the solid discharge port 3. Therefore, a scraper assembly 17 is designed in the solid-liquid separation tank 1. The scraper assembly 17 includes a scraper 17 and an electric telescopic rod 18. One end of the scraper 17 is connected to the inner wall of the solid-liquid separation tank 1 via a connecting shaft. One end of the electric telescopic rod 18 is hinged to the inner wall of the solid-liquid separation tank 1, and the other end of the electric telescopic rod 18 is hinged to the middle of the scraper 17. The electric telescopic rod 18 is used to drive the scraper 17 to rotate around the connecting shaft to adjust the relationship between the scraper 17 and the conveyor belt 5. The solid discharge port 3 is located below the scraper 17, with a through groove 19 on the scraper 17. The scraped solid material is discharged through the through groove 19 to the solid discharge port 3. The electric telescopic rod 18 drives the scraper 17 to rotate around the connecting shaft through the telescopic movement, thereby precisely adjusting the distance between the scraper 17 and the conveyor belt 5. The solid material adhering to the surface of the conveyor belt 5 is scraped off by adjusting the position of the scraper 17. The scraped solid material falls into the solid discharge port 3 below through the through groove 19, completing the collection of solid material.

[0021] Working principle:

[0022] The first step is preliminary filtration of the feed: The material to be processed (containing solids and liquids) enters the solid-liquid separation tank 1 through the feed inlet 2 and falls onto the conveyor belt 5. The conveyor belt 5 is made of a water-permeable material (such as a filter screen or a perforated conveyor belt). The liquid passes through the conveyor belt 5 under the action of gravity, while the solids remain on the surface. The second step is limit adjustment (controlling the material thickness): The height of the baffle 15 is adjusted by the fastening bolts 16 to limit the accumulation thickness of the material on the conveyor belt 5, prevent excessive material from entering the extrusion zone, and ensure the extrusion effect. The third step is mechanical extrusion (extracting residual liquid): The conveyor belt 5 carries the solid material to the extrusion zone between the first pressure bar 6 (fixed lower pressure bar) and the second pressure bar 7 (adjustable upper pressure bar). The lifting structure (handwheel 12, threaded rod 9, nut seat 10, connecting rod) is used. 11) Adjust the height of the second pressure bar 7 to adapt the distance between the two pressure bars to the extrusion requirements of different materials; under the strong extrusion of the pressure bars, the residual liquid of the solid material is further squeezed out and flows into the liquid discharge port 4 through the conveyor belt 5; the fourth step is solid discharge (scraper 17 cleaning): the extruded solids may adhere to the surface of the conveyor belt 5 and cannot be removed by themselves. The scraper 17 is adjusted at an angle under the drive of the electric telescopic rod 18, closely adhering to the surface of the conveyor belt 5, and scraping off the adhered solids. The scraped solids fall into the solid discharge port 3 through the through groove 19 on the scraper 17, completing the collection; among them, liquid and solids are collected separately: liquid: filtered through the conveyor belt 5 throughout the process and collected in the liquid discharge port 4; solids: scraped off by the scraper 17 after extrusion and finally discharged from the solid discharge port 3. In summary, this device achieves efficient solid-liquid separation through conveyor belt 5 filtration + double pressure bar extrusion + scraper 17 cleaning. This device is suitable for food processing and fruit and vegetable pressing scenarios, and is more efficient and controllable than manual operation.
