Technical Field
[0001] This utility model belongs to the technical field of solid-liquid separation devices, and more specifically, it relates to a solid-liquid separation device for food quality testing. Background Technology
[0002] In food testing, it is necessary to analyze and test the nutritional components of food. Sometimes, solid-liquid separation is required to test the liquid and solid separately. Centrifugal force is commonly used to separate the liquid from the food.
[0003] For some foods with high oil content, solid-liquid separation at low temperatures often results in the separated oil clogging the fine pores of the filter, preventing normal solid-liquid separation. Clogging usually requires disassembling the filter, cleaning it, and attempting solid-liquid separation again, or moving the solid-liquid separator to a suitable temperature environment. Such devices have relatively high environmental requirements.
[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a solid-liquid separation device for food quality testing. The device is equipped with a heating device around the filter barrel to maintain a suitable temperature for solid-liquid separation. The device is also equipped with a scraping mechanism to scrape off the liquid adhering to the inner wall of the device in time and transfer it to the filter screen for secondary filtration and discharge, so that the separated liquid is cleaner.

Three springs are fixedly connected to one end of the baffle, with one end of the springs abutting against the bottom of the opening and the other end of the baffle abutting against the mounting hole on the sliding cover.
[0007] Preferably, the scraping mechanism is U-shaped and includes two hollow shafts. Connecting rods are fixedly connected to both sides of the hollow shafts, and a scraper is fixedly connected to one side of the connecting rod. The outer side of one scraper abuts against the inside of the upper cover, and the other scraper abuts against the inside of the base. Half gears are fixedly connected to the hollow shafts on both sides, and the shafts and hollow shafts are nested together.
[0008] Preferably, the heating mechanism includes a fixed shaft fixedly connected to the base, two heating elements fixedly connected to the fixed shaft, and a circular connecting ring fixedly connected between the two heating elements.
[0009] Preferably, one end of the base connecting the drive device is rotatably connected to gear set one and gear two in sequence, and the other end is rotatably connected to gear set two and gear four in sequence. A connecting rod is rotatably connected to one side of the base, gear three is fixedly connected to one side of the connecting rod, and gear five is fixedly connected to the other side. Gear three is meshed with gear two for transmission, and gear five is meshed with gear four for transmission. Gear set one includes two full gears and a middle half gear, and gear set two includes one full gear and one half gear.
[0010] Preferably, the extended end of the drive device is fixedly connected to a gear one, which meshes with the full gear on one side of the gear set one, the half gear in the gear set one meshes with the half gear, the other gear in the gear set one meshes with the gear two, the half gear fixedly connected to the other side of the scraping mechanism meshes with the half gear in the gear set two, and the full gear in the gear set two meshes with the gear four.
[0011] Preferably, a power interface is fixedly connected to the upper base of the connecting rod, and the power interface is electrically connected to the heating mechanism, the control device and the drive device respectively.
[0012] Preferably, a filter screen is fixedly connected to the bottom of the base, and the bottom of the filter screen is provided with a drain port fixedly connected to the base.
[0013] Preferably, a handle is fixedly connected to one side of the upper cover, and a buckle is provided in the middle of the handle for fixed connection with the upper cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model has a heating mechanism inside the base to maintain a constant internal temperature and prevent oily substances from clogging the openings on the filter mechanism due to low temperature. The temperature can also be set to a temperature suitable for solid-liquid separation, ensuring more thorough solid-liquid separation when dealing with different foods.
[0018] 2. This utility model features an internal scraping mechanism comprising two scrapers. These scrapers oscillate within the space enclosed by a base and a top cover. One scraper scrapes the inside of the top cover back and forth, while the other scraper scrapes the inside of the base. This prevents liquid splashing caused by the rotating scrapers. This utility model uses only one drive device to move both the filtration and scraping mechanisms. Gear sets on both sides of the base reduce the power output of the drive device, preventing the scraping mechanism from moving too fast and resulting in incomplete cleaning. This also allows the filtration mechanism to rotate at high speed, improving separation efficiency and making it more energy-efficient.
[0019] 3. The sliding cover on the filter mechanism of this utility model adopts a sliding design, and the baffle abuts against the sliding cover. During the rotation of the filter bucket, the force of the baffle against the sliding cover will increase due to the centrifugal force, making it less likely for the food in the filter bucket to leak. After separation, simply pull the lever on the baffle and slide out the sliding cover to remove the food in the filter bucket, which is more convenient and faster. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings:
[0037] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] like Figures 1 to 15As shown, a solid-liquid separation device for food quality testing is used to separate liquids and solids in food. It includes a base 1, with a filter mechanism 3 rotatably connected inside the base 1. A heating mechanism 5, fixedly connected to the base 1, is located outside the filter mechanism 3. A scraping mechanism 4, perpendicular to the heating mechanism 5, is located outside the heating mechanism 5. A top cover 6 is rotatably connected to one side of the base 1, and a control device 9 is fixedly connected to the other side of the base 1. A drive device 8 is fixedly connected to one end of the base 1. The filter mechanism 3 includes a filter barrel 305, with shafts 306 fixedly connected to both ends of the filter barrel 305. One side of the shaft 306 is fixedly connected to the extended end of the drive device 8. Multiple openings are provided on the barrel wall of the filter barrel 305. The filter has a slot for easy material placement, and a sliding cover 301 is slidably connected inside the slot. The sliding cover 301 has a mounting hole on one side, and the filter bucket 305 on one side of the slot has an opening. A baffle 302 is slidably connected inside the opening, and a wrench 303 is fixedly connected to one side of the baffle 302. Three springs 304 are fixedly connected to one end of the baffle 302. One end of the springs 304 abuts against the bottom of the opening, and the other end of the baffle 302 abuts against the mounting hole on the sliding cover 301. The sliding cover 301 slides on the filter bucket 305. The sliding cover 301 can be fixed and disassembled by pushing the wrench 303 to move the baffle 302, which is simpler and more efficient.
[0039] like Figure 7 As shown, the scraping mechanism 4 is U-shaped and includes two hollow shafts 401. Connecting rods 402 are fixedly connected to both sides of the hollow shafts 401, and scrapers 403 are fixedly connected to one side of each connecting rod 402. The outer side of one scraper 403 abuts against the inside of the upper cover 6, and the other scraper 403 abuts against the inside of the base 1. Half-gears 11 are fixedly connected to the hollow shafts 401 on both sides. Shaft 306 is nested with the hollow shafts 401. The heating mechanism 5 includes a fixed shaft 501 fixedly connected to the base 1. Two heating elements 502 are fixedly connected to the fixed shaft 501. A circular connecting ring 503 is fixedly connected between the two heating elements 502. A wire is provided inside the circular connecting ring 503, and the two heating elements 502 are powered and heated through the wire.
[0040] One end of the base 1 is connected to the drive device 8 and is rotatably connected to gear set 12 and gear 2 13 in sequence. The other end is connected to gear set 2 15 and gear 4 16 in sequence. A connecting rod 105 is rotatably connected to one side of the base 1. Gear 3 14 is fixedly connected to one side of the connecting rod 105 and gear 5 17 is fixedly connected to the other side. Gear 3 14 meshes with gear 2 13 for transmission, and gear 5 17 meshes with gear 4 16 for transmission. Gear set 12 includes two full gears and a middle half gear. Gear set 2 15 includes one full gear and one half gear. This utility model uses gears instead of chains or belts for transmission because gear transmission is more precise, making the half gear 11 fit more precisely and achieve left and right reciprocating motion. Other transmission methods will more or less shift after long-term working environment, resulting in less precise motion.
[0041] Gear 10 is fixedly connected to the extended end of the drive device 8. Gear 10 meshes with the full gear on one side of gear set 12, and when gear 10, with its fewer teeth, meshes with the full gear in gear set 12, it is a speed reduction transmission. Half gears in gear set 12 mesh with half-gear 11, and the other gear in gear set 12 meshes with gear 13. Half-gear 11, fixedly connected to the other side of the scraping mechanism 4, meshes with half gears in gear set 15, and the full gear in gear set 15 meshes with gear 16. A power interface 101 is fixedly connected to the upper base 1 of the connecting rod 105. The power interface 101 is electrically connected to the heating mechanism 5, the control device 9, and the drive device 8. The control device 9 can control the heating mechanism 5 and the drive device 8, including controlling the temperature, speed, and working time.
[0042] like Figure 12 As shown, a filter screen 103 is fixedly connected to the bottom of the base 1. The bottom of the filter screen 103 has a drain port 102 fixedly connected to the base 1. The function of the filter screen 103 is to perform secondary filtration on the liquid after solid-liquid separation, and the filtered liquid is discharged from the drain port. A handle 602 is fixedly connected to one side of the top cover 6. A buckle 601 fixedly connected to the top cover 6 is located in the middle of the handle 602. A movable buckle 104 is rotatably connected to one side of the base 1. One end of the movable buckle 104 abuts against the buckle 601. An elastic device is fixedly connected to the other side of the movable buckle 104 near the base 1. One end of the elastic device is fixedly connected to the base 1. Through the cooperation of the movable buckle 104 and the buckle 601, the top cover 6 will not easily open from the base 1, preventing accidents during operation. Hydraulic rods 7 are rotatably connected to both ends of the base 1. One end of the hydraulic rod 7 is rotatably connected to the top cover 6. The hydraulic rods 7 can assist the operator in opening the cover, making it more labor-saving.
[0043] In this invention, the upper cover 6 is made of transparent acrylic material, facilitating observation of the solid-liquid separation process of food from the outside. The scraping mechanism 4 not only scrapes the filtered liquid onto the base 1 but also cleans the upper cover 6, allowing staff to better observe the internal conditions. The filtering mechanism 3 and the base 1 are made of food-grade stainless steel, as is the main body of the scraping mechanism 4. This ensures that the food undergoing solid-liquid separation is cleaner and more hygienic. The scraper 403 is made of rubber, which scrapes the base 1 and the upper cover 6 without causing damage. A rubber pad is fixed at the opening of the base 1, which is located at the opening of the upper cover 6, increasing the sealing between the base and the upper cover and preventing internal liquid from splashing out during operation.
[0044] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.
[0045] Working process: With the opening of the filter bucket 305 facing upwards, pull the lever 303 downwards. The spring 304 presses downwards, and the baffle 302 slides out from the sliding cover 301. Move downwards to remove the sliding cover 301, place the food to be separated into it, and then slide the sliding cover 301 back into the filter bucket. Activate the heating element 502, hold the handle 602, and close the upper cover 6 and base 1. The latch 601 in the middle of the handle 602 engages with the movable buckle 104 on the base 1, sealing the upper cover 6 and base 1.
[0046] Start the drive device 8. The extended end of the drive device 8 directly drives the filter barrel 305 to rotate. Gear 10 on the extended end of the drive device 8 drives gear set 12 to rotate. Since the number of teeth of gear 10 is less than the number of teeth on gear set 12, gear 10 plays a role in deceleration. The half gear in the middle of gear set 12 drives half gear 11 on scraping mechanism 4 to rotate clockwise half a turn. The gear on the other side of the gear set drives gear 2 13 to rotate. Gear 2 13 drives gear 3 14 fixed on connecting rod 105 to rotate. Gear 5 17 on the other side of connecting rod 105 drives gear 4 16 to rotate. Gear 4 16 drives the full gear on gear set 2 15 to rotate. The half gear on gear set 2 15 drives half gear 11 fixed on the other side of scraping mechanism 4 to rotate counterclockwise. This process is repeated.
[0047] After solid-liquid separation is completed, the filter tank 305 stops rotating, the scraping mechanism 4 also stops rotating, and the filtered liquid is discharged from the device through the drain port 102 after secondary filtration along the filter screen 103 at the bottom of the base 1.
[0048] Cleaning this invention is very simple. Just remove the solid food from the filter bucket 305, remove the sliding cover 301 from the filter bucket 305, remove the filter screen 103, plug the drain port 102, add cleaning solution and water, close the top cover 6, and start the drive device 8 and heating mechanism 5 for idle cleaning. Once cleaning is complete, remove the plugged drain port 102 and drain the wastewater. The high temperature also sterilizes the inside of the device. After cleaning, simply put the cleaned filter screen 103 and sliding cover 301 back in their original positions.
[0049] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
