Description

Technical Field

[0001] This utility model relates to the field of flaxseed oil technology, and in particular to a flaxseed oil purification device. Background Technology

[0002] Flaxseed oil, a functional oil rich in alpha-linolenic acid, is widely used in the food, health products, and cosmetics industries. Its quality depends on the advancement of its purification process. Currently, the purification process is the key to determining the added value of flaxseed oil.

[0003] In the prior art, such as Chinese Patent No. CN220597378U, a purification tank is included. A filter funnel is installed inside the purification tank. The filter funnel has a downward-facing conical trapezoidal structure. A sedimentation tube is installed at the lower end of the filter funnel. The sedimentation tube has a hollow structure, and its upper end face is flush with the lower end face of the filter funnel. The lower end of the sedimentation tube extends from the lower end of the purification tank. A detachable sedimentation tank is installed at the lower end of the sedimentation tube. A movable sleeve is rotatably fitted onto the outside of the sedimentation tube. A collection frame is fixedly connected to the outside of the movable sleeve. An oil pump draws oil and sprays it into the filter holes of the filter funnel, flushing impurities clogging the filter holes back into the filter funnel. This, combined with a motor-driven rotation, can treat all the filter holes of the entire filter funnel, preventing impurities from falling into the filter holes and causing blockages. This allows flaxseed oil to be filtered and purified normally without affecting the normal collection of impurities. Furthermore, the inclined plate ensures that the oil sprayed from each nozzle reaches the filter holes with uniform force.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: after filtering flaxseed oil, the oil is extracted to clean the filter pores of the filter bucket. However, the oil will stick to the surface of both sides of the filter bucket. On the one hand, it will cover part of the filter pore inlet, resulting in a reduction in the actual effective filtration area and a slowdown in the flow rate of the oil through the filter pores. On the other hand, the adhered oil will form an oil film layer. During subsequent filtration, newly introduced impurities are easily combined with the oil film and adhere to the surface of the filter bucket, gradually clogging the filter pores. At the same time, the oil adhering to the surface of the filter bucket will undergo oxidation reaction due to long-term exposure to the air environment inside the equipment, generating oxidation products such as aldehydes and ketones. These oxidation products not only lose their nutritional value but also contaminate the flaxseed oil that is subsequently purified. Therefore, it is necessary to disassemble the filter bucket for cleaning, and also to clean the inside of the purification tank. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where grease sticks to the surfaces on both sides of the filter bucket. On the one hand, this covers part of the filter hole inlet, resulting in a reduction in the actual effective filtration area and a slowdown in the flow rate of oil through the filter holes. On the other hand, the adhered grease forms an oil film layer, and during subsequent filtration, newly introduced impurities easily combine with the oil film and adhere to the surface of the filter bucket, gradually clogging the filter holes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flaxseed oil purification device, comprising a purification tank and a top cover, the flaxseed oil purification device further comprising: Fixing plate two is installed on the outer surface of the bottom of the top cover; Fixing plate one is installed on the outer surface of the top of the purification tank; A filter funnel is located at the top of the inner cavity of the purification tank; The filter funnel is configured as an inverted conical trapezoid. Two mounting plates are installed on both sides of the filter bucket; Two snap-fit ​​connectors are respectively located at the bottom of the two mounting plates; Multiple locking components are disposed between the first fixing plate and the second fixing plate.

[0007] In a preferred embodiment, the snap-fit ​​component includes: A fixing block is installed at the bottom of the mounting plate; Two connecting cylinders are installed on both sides of the fixing block; Two locking pins are slidably installed at both ends of the connecting cylinder; Two elastic elements are disposed inside the two connecting cylinders; The two locking pins are elastically connected to the connecting cylinder via an elastic element.

[0008] The technical effect of adopting the above-mentioned further solution is that, by utilizing the expansion and contraction characteristics of the elastic element, the locking column can slide flexibly inside the connecting cylinder. When the filter bucket is installed into the purification tank through the mounting plate, the locking column can automatically engage with the matching structure under the action of elastic force, thereby achieving rapid positioning and fixing of the filter bucket without the need for additional tools, thus simplifying the installation process.

[0009] In a preferred embodiment, the snap-fit ​​component further includes: A connecting rope is installed inside the fixing block; The two ends of the connecting rope pass through the fixing block and the two connecting cylinders, and the two ends of the connecting rope are connected to one end of the two locking posts. A pull rope is fixedly installed at the top of the middle part of the connecting rope; The pull rope passes through the top of the fixing block and the mounting plate; A pull ring is installed at the top of the pull rope; A placement slot is provided at the top of the mounting plate; The pull ring is adapted to the placement groove.

[0010] The technical advantages of adopting the above-mentioned further solution are as follows: pulling the pull ring can cause the two side locking columns to retract synchronously through the pull rope and connecting rope, quickly releasing the locking state and realizing convenient disassembly of the filter bucket, solving the problem of cumbersome disassembly of traditional fixed structures; the matching design of the pull ring and the placement groove allows the pull ring to be embedded in the placement groove after the filter bucket is installed and fixed, avoiding the pull ring from being exposed and affecting the overall structural regularity of the equipment, while preventing external force from accidentally touching the pull ring and causing the locking to loosen, thus balancing the convenience of operation and structural stability.

[0011] In a preferred embodiment, the locking element includes: Bolts are installed between the first fixing plate and the second fixing plate; The bolt passes through fixing plate one and fixing plate two, and the bolt is threadedly connected to fixing plate one and fixing plate two; A knob is mounted on the top of the bolt.

[0012] The technical effect of adopting the above-mentioned further solution is that the bolt passes through the first fixing plate and the second fixing plate and is connected by threads. By rotating the bolt, the tightness of the fit between the two fixing plates can be precisely adjusted, thereby achieving a firm lock between the top cover and the purification tank. The connection strength is high and can withstand the pressure that may be generated inside the tank during the purification process, thus preventing the top cover from loosening.

[0013] In a preferred embodiment, the flaxseed oil purification apparatus further includes: Two mounting slots are provided on both sides of the top of the purification tank; The two mounting plates are slidably fitted with the mounting grooves.

[0014] The technical effect of adopting the above-mentioned further solution is that the mounting grooves on both sides of the top of the purification tank and the mounting plates on both sides of the filter bucket form a sliding fit structure, which provides a precise guiding effect for the installation of the filter bucket, so that the filter bucket can slide smoothly into the top of the inner cavity of the purification tank along the mounting groove, avoiding damage to the filter bucket from collision with the tank wall due to positional deviation during installation.

[0015] In a preferred embodiment, the flaxseed oil purification apparatus further includes: Two slots are provided on both sides of the top of the purification tank; Among them, the two snap-fit ​​components are adapted to the slots, and the two slots are connected to the mounting grooves.

[0016] The technical effect of adopting the above-mentioned further solution is that the design of the card slot and the mounting slot being connected allows the snap-fit ​​component to be directly aligned with the card slot and snap-fitted when the filter hopper slides along the mounting slot to the preset position via the mounting plate.

[0017] In a preferred embodiment, the flaxseed oil purification apparatus further includes: Two sealing gaskets are respectively installed at the bottom of the top cover and the top of the purification tank.

[0018] The technical effect of adopting the above-mentioned further solution is that the sealing gaskets at the bottom of the top cover and the top of the purification tank can tightly fill the gap between them through the squeezing action after the top cover and the tank body are locked, thus constructing an effective sealing structure. On the one hand, it can prevent flaxseed oil vapor from leaking out of the gaps during the purification process, reducing raw material loss and environmental pollution. On the other hand, it can prevent outside air and impurities from entering the tank and contaminating the flaxseed oil to be purified, ensuring the purity and quality of the purified oil.

[0019] In a preferred embodiment, the flaxseed oil purification apparatus further includes: The feed pipe is connected to the top of the top cover.

[0020] The technical effect of adopting the above-mentioned further solution is that it provides a stable and directional transportation channel for the flaxseed oil to be purified.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, through the design of a purification tank, a top cover, and snap-fit ​​components, enables tool-free assembly and disassembly of the purification tank and filter bucket. Installation, disassembly, and cleaning of the purification tank and filter bucket can be completed without the need for professional personnel. Once opened, residual oil and impurities inside the tank can be directly cleaned, significantly reducing maintenance downtime. After removing the filter bucket, the filter holes and surface can be directly rinsed, and the inner wall of the purification tank can be thoroughly wiped, preventing oil residue oxidation and impurity accumulation. This ensures the purity and active ingredient retention rate of each batch of flaxseed oil, meeting the stringent quality standards of the food and health product industries. The tight snap-fit ​​of the locking posts and slots, along with the threaded locking of the bolts and fixing plates, forms a multi-layered fixing structure, ensuring that the filter bucket will not shift due to oil impact during filtration. The connection between the top cover and the purification tank is also more secure.

[0022] This invention provides a precise sliding guide for the filter bucket by setting an installation groove, avoiding positional deviations during manual installation. The matching of the slot and the snap-fit ​​component firmly fixes the filter bucket in the preset position, preventing displacement under the impact of oil. The combination of these two features ensures that the filter bucket maintains a stable filtration posture, ensuring full contact between the oil and the filter surface, reducing filtration dead zones caused by filter bucket shaking, improving the consistency of filtration effect, and guaranteeing the purification accuracy of each batch of flaxseed oil. The double sealing gasket achieves a seamless seal through compression deformation, which is more effective in preventing oil leakage in the purification tank compared to a single sealing structure, reducing oil waste. At the same time, the sealed environment can isolate external air and impurities from entering the tank, preventing the oil from oxidizing and deteriorating due to contact with air, and preventing external pollutants from affecting the purity of the oil, ensuring the quality and safety of flaxseed oil for consumption. It is especially suitable for the stringent requirements for oil purity in the high-end health product field. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1-5 This embodiment provides a flaxseed oil purification device, the specific concept of which is as follows: A flaxseed oil purification device includes a purification tank 1 and a top cover 4. The flaxseed oil purification device also includes: a second fixing plate 3, a first fixing plate 2, a filter hopper 9, two mounting plates 10, and two snap-fit ​​components.

[0027] The fixing plate 2 3 is installed on the outer surface of the bottom of the top cover 4.

[0028] The fixing plate 2 is installed on the outer surface of the top of the purification tank 1.

[0029] The filter hopper 9, which plays a filtering role, is located at the top of the inner cavity of the purification tank 1.

[0030] In addition, the filter hopper 9 is designed as an inverted trapezoidal cone.

[0031] Among them, the two mounting plates 10, which serve the purpose of installation, are installed on both sides of the filter hopper 9.

[0032] The two snap-fit ​​connectors are respectively located at the bottom of the two mounting plates 10.

[0033] As examples, in this embodiment, the snap-fit ​​component includes: a fixing block 13, two connecting cylinders 16, two snap pins 11, two elastic elements 15, a connecting rope 12, a pull rope 14, a pull ring 17, and a placement groove 18.

[0034] The fixing block 13 is installed on the bottom of the mounting plate 10.

[0035] The two connecting cylinders 16 are installed on both sides of the fixing block 13.

[0036] Among them, the two locking pins 11 that play a limiting role are slidably installed at both ends of the connecting cylinder 16.

[0037] The two elastic elements 15 are located inside the two connecting cylinders 16.

[0038] In addition, the two locking posts 11 are elastically connected to the connecting cylinder 16 via elastic elements 15.

[0039] The connecting rope 12 is installed inside the fixing block 13.

[0040] It should be noted that the two ends of the connecting rope 12 pass through the fixing block 13 and the two connecting cylinders 16, and the two ends of the connecting rope 12 are connected to one end of the two locking posts 11.

[0041] The pull rope 14 is fixedly installed at the top of the middle part of the connecting rope 12.

[0042] In addition, the pull rope 14 passes through the top of the fixing block 13 and the mounting plate 10.

[0043] The pull ring 17 is installed on the top of the pull rope 14.

[0044] The placement slot 18 is located on the top of the mounting plate 10.

[0045] In addition, the pull ring 17 is compatible with the placement slot 18.

[0046] In this embodiment, the mounting plates 10 on both sides of the filter hopper 9 are aligned with the mounting groove 20 on the top of the purification tank 1 and inserted. During the process, the elastic element 15 in the connecting cylinder 16 releases its elastic force, pushing the locking post 11 to slide along the connecting cylinder 16 until the end of the locking post 11 is embedded in the locking groove 19 that communicates with the mounting groove 20. With the help of the continuous force of the elastic element 15, the locking post 11 and the locking groove 19 fit tightly together to form a stable locking structure, thereby realizing the quick loading and unloading of the filter hopper 9. Example 2

[0047] Please see Figures 1-5 Based on Example 1, this example provides a flaxseed oil purification device, the specific concept of which is as follows: The flaxseed oil purification device also includes: two mounting slots 20, two card slots 19, two sealing gaskets 8, a feed pipe 5, and multiple locking components.

[0048] The two mounting slots 20 are located on both sides of the top of the purification tank 1.

[0049] In addition, the two mounting plates 10 slide in conjunction with the mounting grooves 20.

[0050] Among them, the two slots 19 that serve as limiting positions are opened on both sides of the top of the purification tank 1.

[0051] It should be noted that the two snap-fit ​​pieces are compatible with the slots 19, and the two slots 19 are connected to the mounting slots 20.

[0052] The two sealing gaskets 8, which serve a sealing function, are respectively installed at the bottom of the top cover 4 and the top of the purification tank 1.

[0053] The feed pipe 5 is connected to the top of the top cover 4.

[0054] The multiple locking components are located between the first fixing plate 2 and the second fixing plate 3.

[0055] As examples, in this embodiment, the locking element includes a bolt 7 and a knob 6.

[0056] The bolt 7 is installed between the fixing plate 1 2 and the fixing plate 2 3.

[0057] In addition, bolt 7 passes through fixing plate 1 2 and fixing plate 2 3, and bolt 7 is threadedly connected to fixing plate 1 2 and fixing plate 2 3.

[0058] The knob 6 is mounted on the top of the bolt 7.

[0059] In this embodiment, during the positioning and limiting stage of the filter hopper 9, the mounting groove 20 and the slot 19 form a dual guiding and fixing mechanism. The mounting groove 20 is opened on both sides of the top of the purification tank 1 and forms a sliding fit with the mounting plates 10 on both sides of the filter hopper 9, providing a precise vertical guiding path for the installation of the filter hopper 9 and preventing the filter hopper 9 from shifting during insertion. When the mounting plate 10 slides along the mounting groove 20 to the preset position, the snap-fit ​​at the bottom of the filter hopper 9 automatically aligns with the slot 19. The snap-fit ​​post 11 in the snap-fit ​​is embedded into the slot 19 under the action of the elastic member 15. With the limiting effect of the slot 19, the filter hopper 9 is fixed to the top of the inner cavity of the purification tank 1, preventing the filter hopper 9 from shifting or shaking laterally due to oil impact during filtration, ensuring that the filter hopper 9 is always in the optimal filtration position. The sealing gasket 8 at the bottom of the top cover 4 and the sealing gasket 8 at the top of the purification tank 1 are squeezed against each other, and the gap between the top cover 4 and the tank body is filled by elastic deformation, blocking the oil leakage channel.

[0060] Working principle: In use, the operator loosens the bolt 7 by rotating the knob 6 to separate the fixing plate 2 from the fixing plate 3. At this time, the top cover 4 can be easily opened. Then, the mounting plates 10 on both sides of the conical trapezoidal filter hopper 9 are aligned with the preset mounting grooves 20 on the top of the purification tank 1 and inserted smoothly until the bottom of the mounting plate 10 is in contact with the inner wall of the mounting groove 20. During the process, the locking mechanism automatically starts working. When the two locking posts 11 move downward, they receive resistance from the top of the mounting groove 20, causing the two locking posts 11 to retract into the connecting cylinder by the elastic force of the elastic element 15. Inside 16, at this time, the fixing block 13 and the two connecting cylinders 16 enter the slot 19. After entering, the elastic force of the elastic element 15 will pop out the locking post 11. Finally, the end of the locking post 11 is precisely embedded in the slot 19 on the top of the purification tank 1, completing the initial positioning and fixing of the filter hopper 9. If the filter hopper 9 needs to be disassembled for cleaning or replacement, simply pull the pull ring 17, and the pull rope 14 will drive the connecting rope 12 to tighten. The two ends of the connecting rope 12 will pull the locking post 11 to compress the elastic element 15 and disengage from the slot 19, so that the filter hopper 9 can be pulled out from the mounting slot 20.

[0061] After the filter hopper 9 is installed in place, close the top cover 4 so that the sealing gasket 8 at the bottom of the top of the purification tank 1 is tightly fitted with the sealing gasket 8 at the top of the purification tank 1 to form a double sealing structure. Then, use bolts 7 to pass through the fixing plate 1 2 and fixing plate 2 3 and tighten the knob 6 to ensure that the connection between the top cover 4 and the purification tank 1 is stable and leak-free. At this time, flaxseed oil can be injected into the device through the feed pipe 5. The oil flows to the conical trapezoidal filter hopper 9 under the action of gravity. The inclined surface of the filter hopper increases the filtration area. After the oil is filtered by the filter hopper 9, it enters the inner cavity of the purification tank 1 to complete the purification. Impurities are trapped on the surface of the filter hopper 9. The specific purification scheme is described in detail in the comparative example, so it will not be repeated in this application.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
