[0027] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] See also Figures 1-4The present embodiment provides a camellia oil purification and filtration device, comprising a filter box 1 with a hollow interior, a filter cartridge 2 with a filter hole, and a cleaning unit 3. The filter cartridge 2 is vertically arranged in the filter box 1, and a discharge port 101 is provided at the bottom of the filter box 1, and the discharge port 101 is located in the filter cartridge 2. A feed port 102 is also provided at the top of the filter box 1. The inside of the filter box 1 and the outside of the filter cartridge 2 together form a filtration space, and the feed port 102 is connected to the filtration space. The cleaning unit 3 includes a cleaning cartridge 310 with a cleaning hole, and the cleaning cartridge 310 is slidably arranged in the filtration space to collect the residue in the filtration space in the cleaning cartridge 310; by providing the cleaning cartridge 310, the cleaning cartridge 310 moves along the vertical direction of the filter box 1, and the residue in the filter box 1 is collected in the cleaning cartridge 310 through the cleaning hole, thereby achieving filtration. The cleaning of the residue in the space allows the raw camellia oil in the filtering space to pass through the filter cartridge 2 smoothly and flow out from the discharge port 101 of the filter box 1 for processing in the next process. This cleaning method will not affect the raw camellia oil flowing into the filtering space through the feed port 102, nor will it affect the filtering process of the raw camellia oil from the filter cartridge 2. Therefore, the raw camellia oil can be filtered while the residue in the filtering space is cleared, solving the problem of existing camellia oil filtering devices that pour the raw camellia oil into the filtering device for filtering. However, as the amount of raw camellia oil filtered by the filtering device increases, the residue remaining in the filtering device also increases. The filtering device needs to be stopped and the residue remaining in the filtering device needs to be cleaned before a new round of camellia oil filtering can be carried out. This method will reduce the overall filtering speed and efficiency.

[0029] It is worth noting that the feed port 102 of the filter box 1 of this solution does not overlap with the cleaning unit 3 when viewed from the vertical direction, ensuring that the cleaning unit 3 removes the residue without affecting the flow of camellia oil into the filter space through the feed port 102.

[0030] In addition, it should be noted that in order to ensure that the residue enters the cleaning cylinder 310 from the cleaning hole, the diameter of the cleaning hole is larger than the maximum diameter of the residue. At the same time, in order to ensure that the filter cylinder 2 can filter the camellia crude oil, the diameter of the filter hole is required to be smaller than the diameter of the residue.

[0031] Furthermore, in order to enable the cleaning cylinder 310 to move along the vertical direction of the filter box 1, the cleaning unit 3 of this scheme also includes a cleaning hydraulic rod 301, which is vertically arranged on the top of the filter box 1. The output end of the cleaning hydraulic rod 301 is sealed and passes through the filter box 1 and is connected to the cleaning cylinder 310. By extending and retracting the output end of the cleaning hydraulic rod 301, the cleaning cylinder 310 can be controlled to rise and fall.

[0032] Furthermore, in order to ensure that the residue in the filter space can enter the cleaning cylinder 310 through the cleaning hole, the cleaning unit 3 of this solution also includes an air blowing pump 303 and a sealing net 302. A sealing hole is coaxially opened at one end of the cleaning cylinder 310 close to the side wall of the filter box 1. The sealing net 302 is slidably arranged on the sealing hole. The air blowing pump 303 is arranged at the end of the cleaning cylinder 310 away from the sealing net 302, and the air blowing pump 303 blows air toward one end of the sealing net 302. By providing the air blowing pump 303 and the sealing net 302, when the air blowing pump 303 starts working, it will absorb the camellia oil in the cleaning cylinder 310 and then pump it out toward the position of the sealing net 302, so that the camellia oil in the cleaning cylinder 310 is pumped out by the air blowing pump 303. The cleaning cylinder 310 moves toward the position of the sealing net 302, thereby flowing out of the cleaning cylinder 310, and the raw camellia oil outside the cleaning cylinder 310 will flow into the cleaning cylinder 310 from the cleaning hole due to the air pressure difference, so that the residue flows into the cleaning cylinder 310 from the cleaning hole. It should be noted that the mesh diameter of the sealing net 302 of the present embodiment is equal to the mesh diameter of the filter hole. Such a setting can ensure that the residue does not flow out from the position of the sealing net 302. Since the cleaning holes are located on the cleaning cylinder 310, the raw camellia oil in the filter space flows into the cleaning cylinder 310 through the cleaning holes. Therefore, due to the force of the raw camellia oil flowing, the residue in the cleaning cylinder 310 is restricted from flowing out of the cleaning hole to the outside of the cleaning cylinder 310.

[0033] It is worth noting that in order to ensure that the raw camellia oil in the cleaning cylinder 310 can flow out of the cleaning cylinder 310 through the sealing net 302, the sealing net 302 of this solution is separated from the side wall of the nearest filter box 1 by a distance of 3 cm to 5 cm. By reserving a distance between the sealing net 302 and the side wall of the nearest filter box 1, the raw camellia oil in the cleaning cylinder 310 can smoothly pass through the sealing net 302 and flow out of the cleaning cylinder 310.

[0034] It should also be noted that, since the cleaning hole is located between the air pump 303 and the sealing net 302, in order to ensure that the pumped camellia oil does not flow out of the cleaning hole into the filter space when the air pump 303 starts working, the present solution also includes a blocking block 4, the cleaning hole is tilted, the opening of the cleaning hole faces the sealing net 302, the blocking block 4 is arranged on the inner wall of the cleaning cylinder 310, the blocking block 4 is tilted, and the inclined end of the blocking block 4 faces the sealing net 302. Since there is a blocking block 4 between the air pump 303 and the opening of the cleaning hole, the camellia oil pumped out by the air pump 303 cannot flow out of the filter space directly from the cleaning hole, and since the inclined end of the blocking block 4 faces the sealing net 302, the pumped camellia oil is further moved toward the sealing net 302 under the guidance of the inertial force and the blocking block 4, thereby achieving the goal that the pumped camellia oil does not flow out of the filter space from the cleaning hole. Furthermore, since the cleaning hole is tilted toward the sealing net 302 , the camellia oil subsequently flowing into the cleaning cylinder 310 will flow toward the sealing net 302 under the force of inertia and the force of the air pump 303 .

[0035] The cleaning unit 305 of the present invention further comprises a hollow cleaning box 304 and a cleaning spring 305. The cleaning box 304 is sealed and penetrates the top of the filter box 1. The interior of the cleaning box 304 is connected to the filtering space in the filter box 1. The end face of the cleaning box 304 in the filter box 1 is in the same vertical plane as the sealing net 302. The two ends of the cleaning spring 305 are respectively connected to the sealing net 302 and the cleaning cylinder 310. The sealing net 302 can lock or release its mutual cooperation with the sealing hole. It should be noted that the highest liquid level of the camellia oil in the filtering space is lower than the lowest setting height of the cleaning box 304, and from the vertical direction, the projection position of the feed inlet 102 of the filter box 1 and the projection position of the cleaning box 304 do not overlap with each other, so as to prevent the camellia oil flowing into the feed inlet 102 from dripping onto the cleaning box 304. By providing a cleaning box 304, when the residue in the cleaning cylinder 310 reaches a certain amount, the cleaning hydraulic rod 301 will start to work, controlling the cleaning cylinder 310 to move toward the top. As the cleaning cylinder 310 moves toward the top, the cleaning cylinder 310 will first move to the liquid surface of the camellia oil. Since there is no camellia oil in the cleaning cylinder 310 at this time, the air pump 303 will suck the air in the cleaning cylinder 310 and pump the air to the position of the sealing net 302, and then the air will flow out of the cleaning cylinder 310 through the sealing net 302. The cleaning cylinder 310 continues to move. The cleaning cylinder 310 moves toward the top, during which the sealing net 302 will abut against the bottom surface of the cleaning box 304; the cleaning cylinder 310 continues to move toward the top, at which time the sealing net 302 stops moving, while the cleaning cylinder 310 continues to move toward the top until the sealing hole of the cleaning cylinder 310 is completely connected to the interior of the cleaning box 304. At this time, the cleaning cylinder 310 stops moving; and due to the wind force of the air pump 303, the residue in the cleaning cylinder 310 will move toward the interior of the cleaning box 304 under the action of the wind force, thereby clearing the residue in the cleaning cylinder 310. After the cleaning cylinder 310 is reset, the sealing net 302 is also reset due to the action of the cleaning spring 305, and the sealing net 302 is locked in its mutual relationship with the sealing hole again.

[0036] It is worth noting that, in this solution, the end face of the sealing net 302 facing the cleaning cylinder 310 is on the same vertical plane as the end face of the cleaning cylinder 310. With this arrangement, when the sealing net 302 moves relative to the cleaning cylinder 310, the residue attached to the sealing net 302 will be retained in the cleaning cylinder 310 again, thereby removing the residue attached to the sealing net 302.

[0037] The cleaning cylinder 310 of this embodiment is cleaned by the hydraulic cylinder 301 of the embodiment of the present invention, and the cleaning cylinder 310 of this embodiment is cleaned by the hydraulic cylinder 301 of the embodiment of the present invention. With such a configuration, when the air pump 303 is working continuously, more and more residues will be attached to the sealing net 302 until the sealing net 302 is completely covered by the residues. At this time, the air pump 303 pumps the camellia oil to the sealing net 302, and the camellia oil cannot flow through the sealing net 302 to the outside of the cleaning cylinder 310. There will be a momentary force, and the force of the air pump 303 will push the sealing net 302 to move along the axial direction of the cleaning cylinder 310; in addition, the cleaning unit 3 of this solution is also provided with a pressing module 5, which is arranged in the connecting slot hole, and the pressing module 5 is in a state of being pressed by the connecting rod 306 under normal circumstances. When the sealing net 302 slides, the sealing net 302 will drive the connecting rod 306 to slide, so that the connecting rod 306 releases its pressing cooperation relationship with the pressing module 5, and the pressing module 5 is communicated with the cleaning hydraulic rod 301. After receiving the signal, the pressing module 5 will control the cleaning hydraulic rod 301 to work. It should be noted that when the air pump 303 pumps the camellia oil to the sealing net 302 and the camellia oil cannot flow through the sealing net 302 to the outside of the cleaning cylinder 310, there will be a momentary force. The force of the air pump 303 will push the sealing net 302 to move along the axial direction of the cleaning cylinder 310. Then, the flow direction of the camellia oil in the cleaning cylinder 310 begins to be disordered. After the sealing net 302 loses the force of the air pump 303, it will be reset due to the force of the connecting spring 308.

[0038] Furthermore, in order to limit the sliding distance of the sealing net 302, the cleaning unit 3 of this scheme also includes a limit block 309, which is arranged in the connecting slot. The limit block 309 is used to limit the stroke of the connecting rod 306. The distance between the limit block 309 and the connecting rod 306 is not greater than the mesh diameter of the sealing net 302. Such a setting can ensure that the gap between the sealing net 302 and the cleaning cylinder 310 will not be greater than the mesh diameter of the sealing net 302, and thus the residue in the cleaning cylinder 310 will not overflow from the gap between the sealing net 302 and the cleaning cylinder 310.

[0039] Furthermore, the present solution is also provided with a stirring component 6, which includes a stirring motor 601, a stirring shaft 602 and a stirring rod 603. The stirring motor 601 is arranged at the top of the filter box 1, and the stirring shaft 602 is coaxially arranged in the filter cartridge 2. The output end of the stirring motor 601 is sealed and extends to the top of the filter box 1. The stirring shaft 602 is coaxially connected to the output end of the stirring motor 601, and the stirring rod 603 is arranged on the stirring shaft 602. By providing the stirring component 6, when the stirring motor 601 starts working, it will drive the stirring shaft 602 to start rotating, and then drive the stirring rod 603 to stir and rotate the camellia crude oil in the filter cartridge 2, so that the residue attached to the side wall of the filter cartridge 2 is separated from the filter cartridge 2, which is convenient for the subsequent cleaning unit 3 to better collect and remove the residue.

[0040] In addition, it is worth mentioning that the stirring rod 603 of the present embodiment is tilted, and the angle between the stirring rod 603 and the bottom of the stirring shaft 602 is an acute angle. Due to the high viscosity and poor fluidity of the camellia oil in the present embodiment at room temperature, the residue of the camellia oil is easy to sink to the bottom, resulting in the residue of the camellia oil being concentrated and accumulated at the bottom of the filter space. The method for collecting residues by the cleaning unit 3 of the present embodiment actually requires that the rotation speed of the camellia oil in the filter space cannot be too high. Therefore, it is necessary to rotate the stirring component 6 at a low speed while making the residue that has sunk to the bottom of the filter space float in the camellia oil. Therefore, the stirring rod 603 must be tilted. Such a setting ensures that during the rotation of the stirring rod 603, there is a force that impacts the residue that has sunk to the bottom of the filter space, so that when the stirring component 6 rotates at a low speed, the residue that has sunk to the bottom of the filter space is impacted and floated.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
