[0002] As a class of biologically active substances that are essential to human health, unsaturated fatty acids play an increasingly important role in modern industrial production and daily life. However, in the process of extracting unsaturated fatty acids from squeezed vegetable oils, oil filtration and impurity removal is one of the key steps in the purification process.

[0003] Traditional unsaturated fatty acid purification methods, such as solvent multi-stage separation method, supercritical extraction method, etc., can effectively separate unsaturated fatty acids, but have obvious deficiencies in oil filtration and impurity removal. For example, some impurity removal equipment in the prior art uses a filter bag to filter the oil statically, which is time-consuming and has a low impurity removal efficiency; while some impurity removal equipment uses a filter cartridge to filter the oil centrifugally, which can improve the efficiency of oil filtration and impurity removal, but the filter residue after filtration is not convenient to clean, and the filter cartridge needs to be disassembled, which is complicated and troublesome to operate.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides an impurity removal device for purifying unsaturated fatty acids, such as Figure 1-10As shown, the impurity removal device for purifying unsaturated fatty acids comprises: a main support 1 fixed on the ground, the main support 1 is U-shaped and is used to support the device; a tank body 2 installed between the inner walls on both sides of the main support 1, and connecting shafts 3 are fixedly installed on both sides of the tank body 2, and two connecting shafts 3 are respectively assembled on the inner walls on both sides of the main support 1; a filter cartridge 4 arranged in the tank body 2 for filtering and removing impurities from the squeezed oil, and filter holes are arranged on the side walls and the bottom inner wall of the filter cartridge 4, and the top of the filter cartridge 4 extends to the outside of the tank body 2; a first rotating mechanism assembled at the bottom of the tank body 2 and a second rotating mechanism assembled on the main support 1, the first rotating mechanism and the second rotating mechanism cooperate to rotate the filter cartridge 4, so that the oil in the filter cartridge 4 undergoes centrifugal motion to quickly filter the oil and filter residue in the filter cartridge 4; a flipping mechanism assembled on the main support 1, used to flip the tank body 2 and the filter cartridge 4 to pour out the filter residue; and a driving mechanism for providing driving force for the flipping mechanism, the second rotating mechanism, and the first rotating mechanism.

[0035] In this embodiment, the impurity removal device realizes efficient filtration and impurity removal of oil and fat and convenient residue treatment in the purification process of unsaturated fatty acids: the main bracket 1 in the impurity removal device serves as the supporting structure of the entire device, and its U-shaped design is stable and reliable, ensuring that the device is firmly fixed on the ground. The tank body 2 is installed between the inner walls on both sides of the main bracket 1, and is connected to the main bracket 1 through two connecting shafts 3 to achieve stable installation. The tank body 2 is the main container for filtering and removing impurities; the filter cartridge 4 is arranged in the tank body 2, and the side walls and the bottom inner wall are provided with filter holes. The top of the filter cartridge 4 extends to the outside of the tank body 2, which is convenient for adding grease and cleaning the filter residue. The design of the filter cartridge 4 allows the grease to be quickly filtered under the action of centrifugal force, effectively improving the impurity removal efficiency; the first rotating mechanism and the second rotating mechanism: these two mechanisms are respectively assembled on the bottom of the tank body 2 and the main bracket 1, and cooperate to rotate the filter cartridge 4. The rotation of the filter cartridge 4 causes the grease to perform centrifugal motion, quickly filtering the filter residue in the filter cartridge 4, and improving the efficiency of filtering and removing impurities; the flipping mechanism is assembled on the main bracket 1, which is used to flip the tank body 2 and the filter cartridge 4, so as to conveniently pour out the filter residue. This design avoids the cumbersome operation of disassembling the filter cartridge to clean the filter residue in traditional impurity removal equipment, and simplifies the operation process; the driving mechanism provides driving force for the flipping mechanism, the second rotating mechanism and the first rotating mechanism, ensuring that the entire impurity removal device can operate efficiently and stably.

[0036] In a further preferred embodiment of the present invention, the first rotating mechanism includes: a circular block 5 fixedly mounted on the inner wall of the bottom of the tank body 2, a first annular groove is provided on the top of the circular block 5 and the bottom of the filter cartridge 4, a plurality of balls are nested in the two first annular grooves, which are used to support the filter cartridge 4 while reducing the resistance to the rotation of the filter cartridge 4; a first rotating shaft 6 rotatably mounted in a rotating hole provided on the circular block 5, the first rotating shaft 6 extending to the bottom of the tank body 2; a connecting tooth column 7 arranged at the top of the first rotating shaft 6 and integrally formed with the first rotating shaft 6, a connecting groove is provided at the bottom of the filter cartridge 4, and annularly distributed teeth are provided on the inner wall of the connecting groove and the outer wall of the connecting tooth column 7, and the connecting tooth column 7 is located in the connecting groove and meshed with the connecting groove; and a connecting block 8 fixedly mounted at the bottom of the first rotating shaft 6, which is used to connect with the second rotating mechanism when the tank body 2 and the filter cartridge 4 are flipped to a vertical state.

[0037] In this embodiment, the first rotating mechanism is refined. Specifically, the circular block 5 is fixed on the inner wall of the bottom of the tank body 2, and together with the bottom of the filter cartridge 4, forms a space for nested balls. These balls are located in the two first annular grooves, which not only provide stable support for the filter cartridge 4, but also greatly reduce the friction resistance of the filter cartridge 4 during the rotation process by rolling. This design not only ensures the smoothness of the rotation of the filter cartridge 4, but also effectively improves its rotation flexibility and response speed; the first rotating shaft 6 is installed on the circular block 5 through the rotating hole and extends to the bottom of the tank body 2. At its top, the integrally formed connecting tooth column 7 is meshed with the teeth in the connecting groove at the bottom of the filter cartridge 4. This meshing structure ensures the stability and reliability of the filter cartridge 4 during the rotation process, and at the same time enables the rotation of the first rotating shaft 6 to directly drive the filter cartridge 4 to rotate. This design not only simplifies the transmission structure, but also improves the transmission efficiency; when the tank body 2 and the filter cartridge 4 are flipped to a vertical state, the connecting block 8 fixed at the bottom of the first rotating shaft 6 is connected to the second rotating mechanism. Through the cooperation between the second rotating mechanism and the connecting block 8, it can be ensured that when the filter cartridge 4 is flipped to a vertical state (ie, when the top opening faces upward), the connecting block 8 can be effectively connected to the second rotating mechanism.

[0038] In a further preferred embodiment of the present invention, the second rotating mechanism includes: a second rotating shaft 9 rotatably mounted on the inner wall at the bottom of the main bracket 1 and vertically arranged; a slot block 10 fixedly mounted on the top of the second rotating shaft 9, the slot block 10 is provided with an entry slot with openings on the top and one side, and the connecting block 8 can enter the entry slot of the slot block 10 when the tank body 2 is flipped, and the connecting block 8 is adapted to the entry slot, that is, when the slot block 10 rotates with the second rotating shaft 9, it can drive the connecting block 8 to rotate; a first supporting block 11 fixedly mounted on one side of the main bracket 1; a central axis 12 rotatably mounted on the first supporting block 11 and vertically arranged; two sprockets 13 fixedly mounted on the second rotating shaft 9 and the central axis 12, and a chain 14 is meshed between the two sprockets 13.

[0039] In this embodiment, the second rotating mechanism is refined. Specifically, the second rotating shaft 9 is vertically arranged and rotatably mounted on the bottom inner wall of the main bracket 1, and the slot block 10 at the top thereof has an entry slot with both the top and one side being open. This design allows the connecting block 8 of the first rotating mechanism to smoothly enter or leave the entry slot of the slot block 10 when the tank body 2 is turned over. This adaptability ensures that when the slot block 10 rotates with the second rotating shaft 9, it can drive the connecting block 8 (and the first rotating shaft 6 and the filter cartridge 4 connected thereto) to rotate synchronously; the first support block 11 is fixedly mounted on one side of the main bracket 1 for stably supporting the middle shaft 12, which is vertically arranged and rotatably mounted on the first support block 11, and it and the second rotating shaft 9 together form a stable rotating structure; two sprocket wheels 13 are respectively fixedly mounted on the second rotating shaft 9 and the middle shaft 12, and they are transmitted through a chain 14. This chain transmission method is not only compact in structure and reliable in transmission, but also can withstand large torque, ensuring the stability and efficiency of the filter cartridge 4 during rotation.

[0040] Based on the above designs, the second rotating mechanism works in conjunction with the first rotating mechanism to provide a stable and efficient rotational driving force for the filter cartridge 4. When the driving mechanism is started, the second rotating shaft 9 and the middle shaft 12 drive the filter cartridge 4 to rotate through the transmission of the sprocket 13 and the chain 14, so that the grease is quickly filtered under the action of centrifugal force, thereby improving the purification efficiency.

[0041] In a further preferred embodiment of the present invention, a first ring block 15 is fixedly installed on the top of the tank body 2, and a second ring block 16 is fixedly sleeved on the outer wall of the filter cartridge 4. The first ring block 15 and the second ring block 16 are arranged concentrically. A second annular groove is opened on the inner wall of the first ring block 15 and a plurality of balls are also embedded therein, all of which are in contact with the outer wall of the second ring block 16. When the filter cartridge 4 rotates, the balls roll in the second annular groove. Through the first ring block 15 and the second ring block 16 and the balls therein, the filter cartridge 4 will not deviate when it rotates.

[0042] In this embodiment, the rotational stability between the tank body 2 and the filter cartridge 4 is further optimized. Specifically, by fixing the first ring block 15 on the top of the tank body 2 and fixing the second ring block 16 on the outer wall of the filter cartridge 4, effective constraint and guidance of the filter cartridge 4 during rotation is achieved. First, the first ring block 15 and the second ring block 16 are designed to be concentrically arranged, which ensures that the filter cartridge 4 can maintain concentricity with the tank body 2 during rotation, thereby avoiding possible deviation or shaking of the filter cartridge 4 during rotation. Secondly, a second annular groove is provided on the inner wall of the first ring block 15, and a plurality of balls in contact with the outer wall of the second ring block 16 are embedded therein. These balls can roll in the second annular groove when the filter cartridge 4 rotates, and rolling friction replaces sliding friction, which significantly reduces the resistance of the filter cartridge 4 during rotation, and at the same time maintains the stable rotation of the filter cartridge 4.

[0043] In a further preferred embodiment of the present invention, the main bracket 1 is also provided with a leak-proof mechanism for covering the top opening of the filter cartridge 4 to prevent grease from being thrown out of the top opening when the filter cartridge 4 rotates, and the leak-proof mechanism includes: two electric telescopic rods 17 fixedly mounted on the top of both sides of the main bracket 1; a mounting ring block 18 fixedly mounted on the top of the output rod of the two electric telescopic rods 17; a cover plate 19 hinged on the top of the mounting ring block 18, and the cover plate 19 and the mounting ring block 18 are equipped with matching buckles for fixing the cover plate 19 and the mounting ring block 18; a third ring block 20 fixedly mounted on the bottom of the cover plate 19; a fourth ring block 21 rotatably mounted on the third ring block 20, and a rubber plug 22 is fixedly mounted on the fourth ring block 21 for plugging the top opening of the filter cartridge 4.

[0044] In this embodiment, a leak-proof mechanism is specially designed to prevent grease from being thrown out from the top opening when the filter cartridge 4 rotates. Specifically, the leak-proof mechanism includes two electric telescopic rods 17, which are fixedly mounted on the top of the two sides of the main bracket 1. A mounting ring block 18 is fixedly mounted on the top of the output rod of the two electric telescopic rods 17 as a support and mounting point. A cover plate 19 is hinged on the top of the mounting ring block 18 to cover the top opening of the filter cartridge 4. In order to ensure that the cover plate 19 can be tightly fixed on the mounting ring block 18, a matching buckle is installed between the two, so that the cover plate 19 can be firmly closed and it is also convenient to open the cover plate 19, so as to facilitate the injection of grease to be filtered into the filter cartridge 4 and to facilitate the removal of the filter cartridge 4, thereby avoiding obstacles to the removal operation of the filter cartridge 4.

[0045] A third ring block 20 is fixedly installed at the bottom of the cover plate 19, and a fourth ring block 21 is rotatably sleeved on the third ring block 20, forming a rotatable connection structure. A rubber plug 22 is fixedly sleeved on the fourth ring block 21, and the rubber plug 22 is used to plug the top of the filter cartridge 4 to prevent grease from being thrown out when the filter cartridge 4 rotates. At the same time, the rotation relationship between the third ring block 20 and the fourth ring block 21 can avoid obstruction to the rotation of the filter cartridge 4 when the top of the filter cartridge 4 is covered.

[0046] In a further preferred embodiment of the present invention, air holes are provided at the center of the rubber plug 22 and the center of the cover plate 19 to connect the filter cartridge 4 with the outside of the external tank body 2, thereby avoiding negative pressure in the filter cartridge 4 when the filter cartridge 4 rotates to throw out the grease and affecting the grease filtering efficiency.

[0047] In this embodiment, the anti-leakage mechanism is further optimized, especially air holes are provided on the rubber plug 22 and the cover plate 19. The design of these air holes is to ensure that when the filter cartridge 4 rotates to throw out the grease through the filter holes on the filter cartridge 4, the inside of the filter cartridge 4 is connected with the outside of the external tank 2, allowing air to freely enter the inside of the filter cartridge 4, thereby balancing the internal and external air pressures, thereby avoiding the generation of negative pressure in the filter cartridge 4 and affecting the grease filtering efficiency.

[0048] In a further preferred embodiment of the present invention, the flipping mechanism includes: two second support blocks 23 fixedly mounted on one side of the main bracket 1; a worm 24 rotatably mounted on the two second support blocks 23; and a worm wheel 25 fixedly sleeved on a connecting shaft 3 close to the worm wheel 24, wherein the worm wheel 25 is meshed with the worm wheel 24.

[0049] In this embodiment, a flipping mechanism is introduced to drive the filter cartridge 4 or other related components to flip, so as to facilitate the dumping of the filter residue. Specifically, the flipping mechanism is composed of the following key parts: two second support blocks 23 are fixedly mounted on one side of the main bracket 1, which provide a stable support basis for the flipping mechanism; the worm 24 is rotatably mounted on the two second support blocks 23, and is the main driving element of the flipping mechanism. By controlling the rotation of the worm 24, the driving of the entire flipping mechanism can be achieved; the worm wheel 25 is fixedly sleeved on a connecting shaft 3 close to the worm 24, and is meshed with the worm 24. This worm gear design drives the rotation of the worm wheel through the rotation of the worm, thereby driving the connecting shaft 3 and the filter cartridge 4 or other components thereon to rotate or flip. The use of this flipping mechanism brings the following significant beneficial effects:

[0050] Stable transmission: Worm gear transmission has the characteristics of large transmission ratio and smooth transmission, which can ensure that the filter cartridge or other components maintain a stable motion state during rotation or flipping.

[0051] Good self-locking property: The worm gear transmission has self-locking property, that is, when the lead angle of the worm is smaller than the equivalent friction angle between the worm gear teeth, the mechanism has self-locking property and can realize reverse self-locking to prevent the filter cartridge 4 or other components from rotating or turning over by themselves after stopping.

[0052] In a further preferred embodiment of the present invention, the driving mechanism includes: a mounting base 26 fixedly mounted on one side of the main bracket 1, and the mounting base 26 is U-shaped; a dual-axis motor 27 assembled on the mounting base 26 and movable up and down, and the two output shafts of the dual-axis motor 27 are vertically arranged; two square rods 28 respectively fixedly mounted on the two output shafts of the dual-axis motor 27; two rectangular sleeves 29 respectively fixedly mounted on the top end of the middle axis 12 and the bottom end of the worm 24, the two square rods 28 are adapted to the two rectangular sleeves 29, that is, when the square rod 28 is inserted into the rectangular sleeve 29, the square rod 28 can drive the rectangular sleeve 29 to rotate as the output shaft of the dual-axis motor 27 rotates.

[0053] In this embodiment, a driving mechanism is designed to provide power for the rotation and flipping of the filter cartridge. First, the core component of the driving mechanism is a U-shaped mounting base 26 fixedly mounted on one side of the main bracket 1. This U-shaped design not only provides stable support, but also facilitates subsequent assembly and adjustment. On the mounting base 26, a double-axis motor 27 that can move up and down is installed. The two output shafts of the double-axis motor 27 are vertically arranged, corresponding to the rotation and flipping mechanisms of the filter cartridge 4 respectively. This double-axis design enables one motor to drive two actions at the same time, simplifies the structure and improves efficiency. On the two output shafts of the double-axis motor 27, two square rods 28 are fixedly mounted respectively. The two square rods 28 are adapted to the other two key components-rectangular sleeves 29. The two rectangular sleeves 29 are fixedly mounted on the top of the middle shaft 12 and the bottom of the worm 24 respectively. When the square rod 28 is inserted into the rectangular sleeve 29, a stable connection relationship is formed between them.

[0054] When the dual-axis motor 27 starts to work, its two output shafts will rotate simultaneously. Due to the close fit between the square rod 28 and the rectangular sleeve 29, the rotation of the square rod 28 will drive the rectangular sleeve 29 to rotate together. In this way, the middle shaft 12 or the worm 24 will receive the power from the dual-axis motor 27, thereby driving the filter cartridge 4 to rotate or flip.

[0055] In a further preferred embodiment of the present invention, a moving mechanism is installed on the mounting base 26 for moving the dual-axis motor 27 vertically so that different square rods 28 can be inserted into the corresponding rectangular sleeves 29, and the moving mechanism includes: a screw rod 30 rotatably installed in a slide groove opened on one side of the mounting base 26 and vertically arranged; a moving seat 31 threadedly sleeved on the screw rod 30, the moving seat 31 is located in the slide groove and slidably connected to the inner wall of the slide groove, and the dual-axis motor 27 is fixedly installed on one side of the moving seat 31; a hexagonal nut 32 fixedly sleeved on the top of the screw rod 30, which is used to facilitate the use of a wrench to twist the hexagonal nut 32, thereby rotating the screw rod 30.

[0056] In this embodiment, in order to more flexibly control the position of the dual-axis motor 27 so that it can accurately adjust the docking relationship with the rectangular sleeve 29, a moving mechanism is specially designed on the mounting base 26. This moving mechanism enables the dual-axis motor 27 to move vertically, ensuring that different square rods 28 can be accurately inserted into the corresponding rectangular sleeve 29. Specifically, the screw rod 30 of the moving mechanism is rotatably mounted in the slide groove opened on one side of the mounting base 26 and is vertically arranged. The screw rod 30 is the core component of the moving mechanism, and its rotation will directly drive the moving seat 31 to move up and down; the moving seat 31 is threadedly sleeved on the screw rod 30 and located in the slide groove. The moving seat 31 is slidably connected with the inner wall of the slide groove, ensuring its stable movement when the screw rod 30 rotates; the dual-axis motor 27 is fixedly mounted on one side of the moving seat 31, so when the moving seat 31 moves up and down, the dual-axis motor 27 will also move accordingly. In order to facilitate the rotation of the screw rod 30, a hexagonal nut 32 is fixedly sleeved on the top of the screw rod 30. The hexagonal nut 32 allows the user to easily turn the screw rod 30 using a tool such as a wrench, thereby controlling the up and down movement of the moving seat 31 and the dual-axis motor 27 .

[0057] In a further preferred embodiment of the present invention, a threaded hole is opened on one side of the mounting base 26 and a first bolt rod 33 is threadedly installed thereon, which is used to press against the moving base 31 after the moving base 31 is adjusted, thereby fixing the moving base 31 and further fixing the position of the dual-axis motor 27. A wrench for tightening the first bolt rod 33 is sleeved on the first bolt rod 33, and the wrench is also used to tighten the hexagonal nut 32.

[0058] In this embodiment, a simple and important improvement is made for the position adjustment and fixation of the dual-axis motor 27. A threaded hole is specially opened on one side of the mounting base 26, and a first bolt rod 33 is threadedly installed through the threaded hole. The design purpose of this first bolt rod 33 is to fix the position of the moving seat 31 by pressing against the moving seat 31 after the moving seat 31 is adjusted to the appropriate position, thereby achieving a stable fixation of the dual-axis motor 27. The advantage of this design is that it provides a simple and effective fixing mechanism. When the position of the dual-axis motor 27 needs to be adjusted to meet different work requirements, the user can drive the screw 30 to rotate by turning the hexagonal nut 32, thereby moving the moving seat 31 up and down in the slide groove. Once moved to the desired position, the user only needs to tighten the first bolt rod 33 to firmly fix the moving seat 31 on the mounting base 26 to ensure the stable operation of the dual-axis motor 27. In addition, in order to facilitate user operation, a wrench is also set on the first bolt rod 33. This wrench can be used not only to screw the first bolt rod 33, but also to screw the hexagonal nut 32. This design eliminates the need for users to frequently change tools, thus improving work efficiency.

[0059] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0060] In another embodiment of the present invention, damping holes are provided on both sides of the main bracket 1, and damping pin rods 34 are slidably installed. Limit blocks 35 are fixedly installed on both sides of the tank body 2. Pin grooves are provided on the sides of the two limit blocks 35 that are away from each other. The two damping pin rods 34 are inserted into the pin grooves of the two limit blocks 35 to fix the tank body 2 to prevent it from flipping over.

[0061] In this embodiment, we have specially designed a mechanism for fixing the tank body 2 to ensure that the tank body 2 can remain stable under certain working conditions and avoid unnecessary overturning. Specifically, damping holes are opened on both sides of the main bracket 1, and damping pins 34 are slidably installed in these holes. At the same time, two limit blocks 35 are fixedly installed on both sides of the tank body 2. These two limit blocks 35 have pin grooves on the sides away from each other. When the tank body 2 needs to be fixed, it is only necessary to insert the two damping pins 34 into the pin grooves of the two limit blocks 35 respectively. This design effectively limits the movement and overturning of the tank body 2 on the main bracket 1 through a physical insertion and locking mechanism, thereby ensuring its stability during operation.

[0062] Through the insertion and cooperation of the damping pin rod 34 and the pin groove of the limit block 35, the tank body 2 is fixed more firmly, effectively avoiding overturning or movement caused by external factors (such as vibration, impact, etc.), thereby ensuring the stability of the working process; the sliding installation method of the damping pin rod 34 makes it very convenient to insert and remove it, and the user can quickly fix or release the tank body 2 as needed, thereby improving the flexibility and convenience of operation.

[0063] In another embodiment of the present invention, an annular groove 36 is provided on the outer wall of the filter cartridge 4, and a threaded hole is also provided on the front side of the tank body 2 and a second bolt rod 37 is threadedly installed. The second bolt rod 37 is used to extend into the annular groove 36 so that the filter cartridge 4 will not fall out of the tank body 2 when it is turned over and the filter residue is dumped.

[0064] In this embodiment, the design of the filter cartridge 4 is further optimized, especially in terms of the stability of its connection with the tank body 2. An annular notch 36 is provided on the outer wall of the filter cartridge 4. This design is very clever and provides new possibilities for fixing the filter cartridge. At the same time, a threaded hole is also provided on the front side of the tank body 2, and a second bolt rod 37 is threadedly installed through this threaded hole. The main function of this second bolt rod 37 is to be able to extend into the annular notch 36 of the filter cartridge 4 when it is necessary to flip and dump the filter cartridge 4 to clean the filter residue, thereby effectively preventing the filter cartridge 4 from detaching from the tank body 2 and falling out. The advantage of this design is that it greatly enhances the stability of the filter cartridge 4 during the flipping process, and when the filter cartridge 4 needs to be rotated to make the grease perform centrifugal motion, the second bolt rod 37 can be rotated to disengage it from the annular notch 36.

[0065] It is worth noting that the circuits, electronic components and modules involved in the present invention are all prior art, and those skilled in the art can fully implement them. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0066] This solution also provides an electric control cabinet, which is installed on the equipment. When in use, each electrical equipment can be started and operated separately through the electric control cabinet. The power connection method of each electrical equipment is an existing mature technology, which is a well-known technology for people in this field and will not be elaborated here.

[0067] In summary, compared with the related art, the present device realizes the rapid separation of impurities in grease by rotating the filter cartridge 4 and utilizing the principle of centrifugal force. Compared with the traditional static filtration, this centrifugal filtration method can significantly improve the efficiency of filtration and impurity removal, reduce processing time, and improve production efficiency.

[0068] The device can flip the filter cartridge 4 to easily dump the filter residue, simplifying the operation steps, improving the convenience of operation, and also facilitating the cleaning of the filter residue, reducing maintenance time and labor costs;

[0069] By setting up a moving mechanism, the device enables the driving mechanism to be flexibly linked with different mechanisms. On the one hand, it can be linked with the second rotating mechanism and the first rotating mechanism to stably drive the filter cartridge 4 to perform centrifugal filtration; on the other hand, it can also be linked with the flipping mechanism to flip the tank body 2 and the filter cartridge 4 to dump the filter residue. This design reduces the number of power equipment used, reduces costs, and also improves the flexibility and adaptability of the equipment.
