DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, 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.

[0021] See also Figure 1-Figure 4 The present embodiment provides a camellia oil purification and filtration device, comprising a filter box 1 with a hollow interior, a filter cartridge 2 with filter holes, and a cleaning unit 3. The filter cartridge 2 is vertically arranged in the filter box 1, and a discharge port 101 is arranged 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 arranged 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 comprises 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 smoothly through the filter cartridge 2 and flow out from the discharge port 101 of the filter box 1 for processing in the next process. Such a 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 residue in the filtering space can be cleared while filtering the raw camellia oil, thereby solving the problem that the existing camellia oil filtering devices all 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 to clean the residue remaining in the filtering device before a new round of camellia oil filtering can be carried out. Such a method will reduce the overall filtering speed and efficiency.

[0022] It is worth noting that the feed inlet 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 the raw camellia oil into the filter space through the feed inlet 102 .

[0023] 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 raw oil, the diameter of the filter hole is required to be smaller than the diameter of the residue.

[0024] 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 the present 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 to be connected with 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.

[0025] 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 the present 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 one 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 to work, it will absorb the camellia raw oil in the cleaning cylinder 310, and then pump it out toward the position of the sealing net 302, so that the camellia raw oil in the cleaning cylinder 310 is pumped out by the air blowing pump 303. The camellia oil outside the cleaning cylinder 310 moves toward the position of the sealing net 302, thereby flowing out of the cleaning cylinder 310, and the 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 size of the sealing net 302 of the present scheme is equal to the mesh diameter size of the filter hole. Such a setting can ensure that the residue will not flow out from the position of the sealing net 302, and because the cleaning holes are arranged on the cleaning cylinder 310, the camellia oil in the filtration space flows into the cleaning cylinder 310 through the cleaning holes. Therefore, due to the force of the 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.

[0026] 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 spaced 3cm-5cm from the side wall of the nearest filter box 1. A space is reserved between the sealing net 302 and the side wall of the nearest filter box 1, so that the raw camellia oil in the cleaning cylinder 310 can smoothly flow out of the cleaning cylinder 310 through the sealing net 302.

[0027] 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 will not flow out of the cleaning hole into the filter space when the air pump 303 starts to work, the present solution also includes a shielding block 4, the cleaning hole is tilted, the opening of the cleaning hole faces the sealing net 302, the shielding block 4 is arranged on the inner wall of the cleaning cylinder 310, the shielding block 4 is tilted, and the inclined end of the shielding block 4 faces the sealing net 302. Since there is a shielding 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 shielding 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 shielding block 4, thereby achieving the goal that the pumped camellia oil will 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 .

[0028] In order to remove the residue in the cleaning cylinder 310, the cleaning unit 3 of the present scheme also includes a cleaning box 304 and a cleaning spring 305 with a hollow interior. 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 located 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 relationship 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 port 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 in from the feed port 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, and control the cleaning cylinder 310 to move toward the top. During the movement of the cleaning cylinder 310 toward the top, the cleaning cylinder 310 will first move to the liquid surface of the raw camellia oil. Since there is no raw camellia oil in the cleaning cylinder 310 at this time, the air pump 303 will absorb the air in the cleaning cylinder 310, and pump the air to the position of the sealing net 302, and then flow out of the cleaning cylinder 310 through the sealing net 302; the cleaning cylinder 310 continues to The cleaning cylinder 310 moves toward the top, during which the sealing net 302 will be in contact with 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 will no longer move, and the cleaning cylinder 310 will continue to move toward the top until the sealing hole of the cleaning cylinder 310 is completely connected with the inside of the cleaning box 304, at which 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 inside of the cleaning box 304 under the force of the wind force, so that the residue in the cleaning cylinder 310 is removed. 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 re-locks its mutual cooperation relationship with the sealing hole.

[0029] It is worth noting that, in this scheme, 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 achieving the removal of the residue attached to the sealing net 302.

[0030] According to the above embodiments, when the residue in the cleaning cylinder 310 reaches a certain amount, the cleaning hydraulic rod 301 will start to work. In order to detect that the residue in the cleaning cylinder 310 reaches a certain amount, the cleaning unit 3 of this scheme also includes a connecting rod 306, a sliding block 307 and a connecting spring 308. The side wall of the cleaning cylinder 310 is also provided with a connecting slot, and the axial direction of the connecting slot is the same as the axial direction of the cleaning cylinder 310. The sealing net 302 can slide along the axial direction of the cleaning cylinder 310. The connecting rod 306 is slidably arranged in the connecting slot, and the sliding block 307 is slidably arranged at one end of the sealing net 302 close to the cleaning cylinder 310. The sliding direction of the sliding block 307 on the sealing net 302 is perpendicular to the sliding direction of the connecting rod 306. The connecting rod 306 and the sliding block 307 are connected to each other. The connecting spring 308 is arranged in the connecting slot, and the two ends of the connecting spring 308 are respectively connected to the connecting rod 306 and the cleaning cylinder 310; 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 residues completely cover the sealing net 302. 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 scheme 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 conditions. 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 connected to the cleaning hydraulic rod 301 for communication. 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, 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, and then the flow direction of the camellia oil in the cleaning cylinder 310 will begin 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.

[0031] 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, and the distance between the limit block 309 and the connecting rod 306 is not larger 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 tube 310 will not be larger than the mesh diameter of the sealing net 302, and thus the residue in the cleaning tube 310 will not overflow from the gap between the sealing net 302 and the cleaning tube 310.

[0032] Furthermore, the present scheme 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. The stirring rod 603 is arranged on the stirring shaft 602. By providing the stirring component 6, when the stirring motor 601 starts to work, 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.

[0033] In addition, it is worth mentioning that the stirring rod 603 of the present embodiment is tilted, and the bottom angle between the stirring rod 603 and 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 the residue 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 large. Therefore, the stirring component 6 needs to rotate at a low speed and make 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 allows the stirring rod 603 to have a force to impact the residue that has sunk to the bottom of the filter space during its rotation, so that the stirring component 6 can impact the residue that has sunk to the bottom of the filter space to float when the rotation speed is low.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. 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.
