Description

Technical Field

[0001] This utility model relates to the field of food additive detection technology, specifically a vacuum filtration device for food additive detection. Background Technology

[0002] Food additives are chemically synthesized or natural substances added to food to improve its quality, color, aroma, and taste, as well as for preservation and processing needs. However, excessive amounts of food additives can harm the human body, so detection devices are needed to detect the content of food additives. A filtration device is an auxiliary device for detecting food additives.

[0003] The prior art, disclosed in CN222419741U, provides a vacuum filtration device for detecting food additives, including an upper tube with a lower tube installed at its bottom. A filter screen is fixedly installed in the middle of the inner side of the upper tube, and a scraper is rotatably installed in the middle of the inner side of the upper tube, above the filter screen. An air pump is connected to the upper part of one end of the upper tube, a filter plate is provided at the bottom of the upper tube, and a water pump is fixedly installed on the outer side of one end of the lower tube. This invention features a scraper rotatably installed above the filter screen, which continuously scrapes away impurities on the filter screen, preventing impurities from accumulating at the screen opening. Simultaneously, the air pump increases the internal pressure of the upper tube, improving filtration efficiency. The vacuum filtration device is assembled from multiple modules, facilitating disassembly and internal cleaning.

[0004] The aforementioned patent primarily utilizes a scraper to continuously scrape away impurities on the filter screen, preventing them from accumulating at the screen opening. Simultaneously, an air pump increases the internal pressure of the upper pipe, thereby improving filtration efficiency. However, this method of scraping away impurities only removes impurities from the surface of the filter screen. Food residue adheres directly to the filter screen pores, causing the scraper to be unable to remove the food residue from within the pores. Accumulated food residue prevents food from passing through the filter screen, thus hindering the detection of food additives. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum filtration device for detecting food additives, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for food additive detection, comprising a lower cylinder, a filter body detachably mounted on the top of the lower cylinder, and a suction assembly for gas extraction fixedly mounted in the middle of the filter body. The suction assembly includes a suction fan, the inner tube of which is sealed and inserted into the filter body, and the outer tube of which is located outside the filter body. A filling sealing membrane is sealed to the outer surface of the filter body for sealing the top of the filter body. The filter body includes a filter assembly for filtering food, comprising an inverted frustum-shaped filter funnel. A bottom scraper and a side scraper are rotatably mounted on the bottom and sides of the filter funnel. Multiple electric push rods for inserting into filter holes are movably mounted on the side of the side scraper away from the filter funnel. The movable mounting of multiple electric push rods on the side of the side scraper away from the filter funnel allows the filtration device for food additive detection to directly clean the filter holes of the filter body, greatly improving the quality of impurity removal.

[0007] Furthermore, an L-shaped support is fixedly installed on the top side of the side scraper, and multiple electric push rods are fixedly installed on this support. A controller is fixedly installed on the side of the support away from the electric push rods, and the controller is electrically connected to the multiple electric push rods. Multiple holes are provided on the side scraper for filtered food to fall through. These holes allow food to be filtered normally through the suction assembly even when the bottom scraper and side scraper are not in use, improving the practicality of the suction filtration device for food additive detection.

[0008] Furthermore, an L-shaped drive body is fixedly installed at the top of the side scraper, and a motor is fixedly installed on the side of the filter funnel away from the side scraper. The motor drives the bottom scraper and side scraper to rotate around the filter funnel. This motor-driven rotation of the bottom scraper and side scraper around the filter funnel significantly improves the integrity of the internal structure of the suction filtration device for food additive testing.

[0009] Furthermore, the filter body includes a housing, with a support bar fixedly connected to the top of the housing, and the motor is fixedly mounted on the support bar. The motor's fixed mounting on the support bar improves the operational stability of the internal structure of the suction filtration device for food additive testing.

[0010] Furthermore, a perforated support member is fixedly connected to the end of the outer shell away from the support bar. A support shaft is fixedly installed at the center of the end of the support member near the support bar, and the bottom of the filter funnel is fixedly installed on the support shaft. This fixed installation of the bottom of the filter funnel on the support shaft allows the filter funnel to be supported as a whole, improving the operational safety of the vacuum filtration device for food additive testing.

[0011] Furthermore, the lower cylinder includes a shell, with an mounting plate fixedly installed on the top of the shell. The shell is fixedly installed at the bottom of the filter body via the mounting plate. An inspection slot for placing filtered food is provided inside the shell. This inspection slot allows filtered food to be directly placed into the inspection slot for storage, improving the efficiency of the food additive testing filtration device for material storage.

[0012] Furthermore, a side plate is fixedly installed at the bottom of the outer casing, and the side plate is attached to the mounting plate. The side plate and the mounting plate are fixedly installed together by bolts. This bolted installation of the side plate and the mounting plate improves the overall robustness of the suction filtration device for food additive testing. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention improves the practicality of the food additive testing vacuum filter device by arranging the filter body in the shape of an inverted frustum and installing a retractable electric push rod on the side scraper for removing impurities. The bottom scraper and side scraper can rotate around the filter body, allowing the electric push rod to extend outwards and enter the filter holes when the food additive testing vacuum filter device removes impurities, thus pushing out the impurities.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A filtration device for detecting food additives includes a lower cylinder 3. A filter body 2 is detachably mounted on the top of the lower cylinder 3. An extraction assembly 1 for extracting and releasing gas is fixedly mounted in the middle of the filter body 2. The extraction assembly 1 includes an extraction fan. The inner tube of the extraction fan is sealed and inserted into the filter body 2, while the outer tube of the extraction fan is located outside the filter body 2. A filling and sealing membrane 4 is sealed to the outer surface of the filter body 2, sealing the top of the filter body 2. The filter body 2 includes a filter assembly 22 for filtering food, which includes an inverted frustum. A filter funnel 224 is shaped like a bottom. A bottom scraper 225 and a side scraper 226 are rotatably mounted on the bottom and sides of the filter funnel 224. Multiple electric push rods 223 for inserting into filter holes are movably mounted on the side of the side scraper 226 away from the filter funnel 224. An L-shaped support is fixedly mounted on the top side of the side scraper 226, and the multiple electric push rods 223 are fixedly mounted on this support. A controller 228 is fixedly mounted on the side of the support away from the electric push rods 223. The controller 228 is electrically connected to the multiple electric push rods 223. An opening is located on the side scraper 226. The filter body 2 has multiple holes 227 for filtered food to fall through. An L-shaped drive body 222 is fixedly installed at the top of the side scraper 226. A motor 221 is fixedly installed on the side of the drive body 222 away from the side scraper 226. The motor 221 drives the bottom scraper 225 and the side scraper 226 to rotate around the filter funnel 224. The filter body 2 includes a shell 21. A support bar 26 is fixedly connected to the top of the shell 21. The motor 221 is fixedly installed on the support bar 26. A perforated support member 23 is fixedly connected to the end of the shell 21 away from the support bar 26. A support shaft 24 is fixedly installed at the center of one end of the support member 23 near the support bar 26. The bottom of the filter funnel 224 is fixedly installed on the support shaft 24. The lower cylinder 3 includes a cylinder shell 33. An installation plate 32 is fixedly installed on the top of the cylinder shell 33. The cylinder shell 33 is fixedly installed at the bottom of the filter body 2 through the installation plate 32. A detection groove 31 for placing filtered food is opened inside the cylinder shell 33. A side plate 25 is fixedly installed at the bottom of the outer shell 21. The side plate 25 is attached to the installation plate 32. The side plate 25 and the installation plate 32 are fixedly installed by bolts.

[0025] Since the filter funnel 224 is fixedly installed on the support shaft 24 of the support member 23, and the bottom scraper 225 and the side scraper 226 are rotatably installed on the outside of the filter funnel 224, when the motor 221 is running, the motor 221 will drive the bottom scraper 225 and the side scraper 226 to rotate around the filter funnel 224 through the drive body 222, so as to remove impurities from the outside of the filter funnel 224.

[0026] Since the side scraper 226 has holes 227, when the side scraper 226 is not rotating, the filtered food can fall down through the holes 227 without affecting the normal filtration of the filter funnel 224. When the side scraper 226 needs to filter the filter holes in the filter funnel 224, it only needs to drive the electric push rod 223 to extend through the single-chip microcomputer control board in the controller 228. The extended electric push rod 223 can directly push out impurities through the holes 227.

[0027] The bottom scraper 225 can also be fitted with an electric push rod, just like the side scraper 226, so that the electric push rod 223 can directly clean the impurities in the filter holes at the bottom of the filter funnel 224.

[0028] Since the filling sealing membrane 4 can directly seal the top of the filter body 2, when the vacuum pump in the vacuum assembly 1 is running, it can directly perform vacuum filtration inside the filter body 2, so that the food can be filtered through the filter funnel 224 for solid-liquid separation. Since the vacuum pump is a very mature existing technology, this utility model has not been described in detail.

[0029] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the food additive testing filtration device are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the food additive testing filtration device, the user places the food to be filtered into the filter funnel 224. The user then seals the top of the filter body 2 by filling with the sealing membrane 4. Subsequently, the user starts the vacuum pump in the vacuum assembly 1 to perform a vacuuming operation inside the filter body 2, causing solid-liquid separation of the food within the filter funnel 224. When the food additive testing filtration device needs to clean impurities from the filter funnel 224, the user starts the motor 221. At this time, the motor 221 drives the drive body 222, the bottom scraper 225, and the side scraper 226 to rotate around the support shaft 24, thereby causing the bottom scraper 225 and the side scraper... 226 rotates around the outside of the filter funnel 224 and scrapes away impurities from the outside of the filter funnel 224. When the user needs to clean the filter holes inside the filter funnel 224, the user needs to activate the electric push rod 223 through the controller 228, and in conjunction with the rotation of the motor 221, the electric push rod 223 can push away the internal impurities in the filter holes inside the filter funnel 224. The filtered liquid will fall into the detection tank 31. At this time, the user can remove the screws fixed on the side plate 25 to remove the entire filter body 2. The user can then use the cylinder shell 33 to test the filtered liquid inside for food additives. This allows the food additive testing filtration device to effectively clean the impurities in the filter holes inside the filter funnel 224 when cleaning impurities, greatly improving the practicality of the food additive testing filtration device.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
