Description

Technical Field

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

[0002] Impurities in camellia seed oil come from a wide range of sources, including substances present in the raw materials and introduced during processing, such as residues and soil particles remaining during pressing or leaching. Although these can be removed by filtration, fine particles can easily clog the filter media, leading to a decrease in filtration efficiency. This necessitates frequent cleaning or equipment replacement, which seriously affects production efficiency and oil quality.

[0003] The main problem with existing camellia seed oil purification devices in related technologies is that the filter screen is easily clogged by impurities. As the filtration time increases, the filter cake thickness increases, the filtration resistance increases, resulting in a decrease in filtration efficiency, and frequent shutdowns are required to clean or replace the filter screen. Utility Model Content

[0004] This invention proposes a purification device for camellia seed oil to solve the problem mentioned in the background art where the filter screen is easily clogged by impurities, resulting in reduced filtration efficiency.

[0005] The technical solution of this utility model is implemented as follows: A purification device for camellia seed oil includes an oil tank with a primary screen installed inside and a support on the outside, which is placed on a heating tank. The lower end of the oil tank has a first oil inlet controlled by a first valve. The first oil inlet is connected to an interface at the upper end of the heating tank. A pipe heater and a first water inlet are located on the side of the heating tank. The first water inlet has a second valve and is connected to a cleaning tank below via a first water supply pipe. The bottom of the heating tank has a second oil inlet and a first wastewater inlet. The second oil inlet has a third valve and is connected to a third oil inlet on a filter tank. The first wastewater inlet has a fourth valve. One end of a first wastewater pipe is connected to the first wastewater inlet, and the other end is connected to a wastewater tank below. The filter tank has a fourth oil inlet with a fourth valve and is connected to a fifth oil inlet on a centrifuge. A collection port is located below the centrifuge.

[0006] By adopting the above technical solution, multi-stage filtration and centrifugal separation are combined. From the initial screening screen to intercept large particles of impurities, to the filtration tank to remove small particles and colloids, and then to the centrifuge to separate impurities of different densities, the precision is gradually improved, effectively enhancing the purification and clarification. A heating device and a cleaning system are added. The heating device heats the camellia seed oil to ensure its fluidity during filtration. The cleaning system delivers the cleaning liquid from the cleaning tank to the required location. After cleaning, the wastewater flows into the wastewater tank. A distiller is also provided to achieve the recycling of the cleaning liquid, ensuring stability during filtration. Multiple valves are set up to effectively control the flow and opening / closing of each interface, which can be freely adjusted according to specific production conditions.

[0007] Preferably, the primary screening screen has regularly arranged small holes, and its upper end is installed on the oil tank by a snap fastener.

[0008] By adopting the above technical solution, the regularly arranged small holes ensure full utilization of the filtration area, enabling uniform and efficient filtration of camellia seed oil when it enters. The snap-fit ​​design allows for quick disassembly and installation, greatly saving maintenance costs.

[0009] Preferably, the upper interface of the heating tank is shaped like a frustum.

[0010] By adopting the above technical solution, the frustum-shaped interface is easier to position during installation, improving the accuracy of docking.

[0011] Preferably, the wastewater tank and the cleaning tank are fixed below the heating tank, there is a partition between the wastewater tank and the cleaning tank, and a distiller is located on one side of the wastewater tank and the cleaning tank. The input end of the distiller is connected to the wastewater tank, and the output end is connected to the cleaning tank.

[0012] By adopting the above technical solution, the wastewater tank and the cleaning tank are fixed below the heating tank, making full use of the space and achieving compact installation of the device. The partition plate clearly defines the functional areas of the wastewater tank and the cleaning tank. The distiller can distill the wastewater collected in the wastewater tank and recover and output the cleaning liquid to the cleaning tank, reducing waste and realizing the recycling of the cleaning liquid.

[0013] Preferably, the filter tank contains a ceramic filter element, has a second water inlet and a second water supply pipe at the upper end, a fifth valve at the second water inlet, a third oil supply port on the side of the filter tank, a second wastewater port at the lower end of the filter tank, a seventh valve at the second wastewater port, the second wastewater port is connected to a wastewater tank through the other end of the second wastewater pipe, the upper end of the ceramic filter element is connected to the water inlet, and the lower end is connected to the fourth oil supply port, a sixth valve at the fourth oil supply port.

[0014] By adopting the above technical solution, the internal ceramic filter element has good filtration performance. It has a fine and stable pore structure inside, which can achieve high-precision filtration. The upper end of the ceramic filter element is connected to the water inlet. The filter element is cleaned by reverse water flow. After cleaning, the wastewater flows out from the wastewater outlet and flows into the wastewater tank through the second wastewater pipe.

[0015] Preferably, the centrifuge has a fifth oil inlet on its side, a hollow shaft and a diaphragm inside, a motor connected to the hollow shaft installed at the top of the centrifuge, the diaphragm is evenly installed on the hollow shaft, the outside of the diaphragm is covered with a polymer membrane, and the inside of the diaphragm is provided with several guide grooves.

[0016] By adopting the above technical solution, the motor is installed at the top of the centrifuge and connected to the hollow shaft 1003, driving the hollow shaft to rotate at high speed. The membranes evenly installed on the hollow shaft increase the separation area. The high-speed rotation of the membranes causes the camellia seed oil to form a tangential flow velocity on the surface of the polymer membrane. Under the action of the tangential flow velocity, cross-flow filtration is achieved. In addition, the internal guide groove of the membrane can effectively guide the flow of the camellia seed oil, ensuring that it can enter the hollow shaft and finally be collected through the hollow shaft to the collection port at the bottom of the centrifuge for discharge.

[0017] Preferably, a water pump is located on the side of the cleaning tank, and the water pump is connected to a first water supply pipe and a second water supply pipe.

[0018] By adopting the above technical solution, the water pump can accelerate the transmission speed of the cleaning fluid, ensuring that the cleaning task can be completed quickly. The two pipes are independent of each other, allowing for the selection of a single location for cleaning, and the independent pipes are easier to maintain.

[0019] Preferably, the pipe heater has heating pipes on both sides, and the heating pipes are connected to the heating tank.

[0020] By adopting the above technical solution, the oil from camellia seeds is extracted from the heating tank by one heating pipe, heated by the pipe heater, and then input into the heating tank through the other heating pipe, forming a flow circulation in the heating tank, which results in faster heat transfer.

[0021] By adopting the above technical solution, the beneficial effects of this utility model are as follows: Through multiple filtration processes—primary screening with regular small holes, filter tank filtration, and centrifuge separation—the filtration accuracy is greatly improved, enabling better removal of various impurities from materials. The frustum-shaped interface, snap-fit ​​connection, and valve-equipped interface design facilitate rapid installation and disassembly, reducing maintenance costs. This device boasts higher space utilization, and its compact layout improves upon the fragmented and poorly coordinated nature of existing equipment. Furthermore, the wastewater recycling process and efficient heating design achieve water resource recycling and energy conservation. Attached Figure Description

[0026] See Figures 1-6 A purification device for camellia seed oil includes: an oil tank 1 with a primary screen 101 installed inside; a support 105 on the outside of the oil tank 1, the support 105 being mounted on a heating tank 2; a first oil inlet 102 controlled by a first valve 103 at the lower end of the oil tank 1; the first oil inlet 102 being connected to an upper interface 201 of the heating tank 2; a pipe heater 3 and a first water inlet 202 on the side of the heating tank 2; a second valve 203 on the first water inlet 202; the first water inlet 202 being connected to a lower cleaning tank 5 via a first water supply pipe 401; and a bottom of the heating tank 2 having... The second oil inlet 204 is connected to the first wastewater inlet 206. The second oil inlet 204 has a third valve 205 and is connected to the third oil inlet 901 on the filter tank 9 on the other side. The first wastewater inlet 206 has a fourth valve 207. One end of the first wastewater pipe 208 is connected to the first wastewater inlet 206, and the other end is connected to the wastewater tank 7 below. The filter tank 9 has a fourth oil inlet 905 and a fourth valve 207. The fourth oil inlet 905 is connected to the fifth oil inlet 1001 on the centrifuge 10. There is a collection port 1006 below the centrifuge 10.

[0027] Specifically, the primary screening screen 101 has regularly arranged small holes on its ground and sides, and its upper end is attached to the oil tank 1 by a snap fastener. Camellia seed oil is poured into the oil tank 1 for filtration, and large particles of impurities are intercepted by the primary screening screen 101.

[0028] Specifically, the wastewater tank 7 and the cleaning tank 5 are fixed below the heating tank 2, and there is a partition 6 between the wastewater tank 7 and the cleaning tank 5. There is a distiller 8 on one side of the wastewater tank 7 and the cleaning tank 5. The input end of the distiller 8 is connected to the wastewater tank 7, and the output end is connected to the cleaning tank 5. The lower end of the distiller 8 is an evaporation tower 801, which is responsible for extracting the wastewater in the wastewater tank 7 for heating and distillation, and the upper end is a condensation tower 802, which is responsible for collecting the distilled cleaning liquid and transporting it into the cleaning tank 5.

[0029] Specifically, the filter tank 9 has a ceramic filter element 902 inside, a second water inlet 903 and a second water supply pipe 402 at the upper end, and a fifth valve 904 on the second water inlet 903, which can flexibly control the entry of cleaning liquid. The filter tank 9 has a third oil outlet 901 on the side. Camellia seed oil is output from the second oil outlet 204 of the heating tank 2 and enters the filter tank 9 from the third oil outlet 901. The filter tank 9 has a second wastewater outlet 907 at the lower end, and a seventh valve 908 on the second wastewater outlet 907. The second wastewater outlet 907 is connected to the lower end of the wastewater tank 7 and the fourth oil outlet 905 through the other end of the second wastewater pipe 909. The fourth oil outlet 905 has a sixth valve 906, which is responsible for controlling whether the filter tank 9 outputs.

[0030] Specifically, the centrifuge 10 has a fifth oil inlet 1001 on its side, and a hollow shaft 1003 and a diaphragm 1004 inside. A motor 1002 is installed at the upper end of the centrifuge 10 and connected to the hollow shaft 1003. The diaphragm 1004 is evenly installed on the hollow shaft 1003. The outside of the diaphragm 1004 is covered with a polymer membrane. The inside of the diaphragm 1004 is provided with several guide grooves 1005. The diaphragm 1004 rotates synchronously at high speed with the hollow shaft 1003, and uses centrifugal force to quickly separate different components in the camellia seed oil. At the same time, the camellia seed oil forms a tangential flow velocity on the surface of the polymer membrane. Under the action of the tangential flow velocity, cross-flow filtration is achieved. The guide grooves 1005 inside guide the camellia seed oil to flow orderly in the diaphragm 1004 and enter the hollow shaft 1003. The filtered camellia seed oil flows out from the collection port 1006 at the lower end of the centrifuge 10.

[0031] Specifically, there is a water pump 4 on the side of the cleaning tank 5. The water pump 4 is connected to a first water supply pipe 401 and a second water supply pipe 402. The water pump 4 can significantly speed up the delivery of the cleaning liquid, ensuring that the cleaning liquid can be delivered quickly and stably from the cleaning tank 5 to the place where it is needed, meeting the need for timely cleaning. The water pump 4 has multiple interfaces 201, which can be connected to more pipes and distributed to different locations according to the actual working conditions.

[0032] Specifically, the pipe heater 3 has heating pipes 301 on both sides, which are connected to the heating tank 2. One end of the heating pipe 301 draws out the camellia seed oil from the heating tank 2, heats it through the pipe heater 3, and then inputs it into the heating tank 2 through the other end of the heating pipe 301, forming a flow circulation in the heating tank 2.

[0033] Specifically, membrane 1004 utilizes the selective permeability of the membrane as the basis for separation. By generating centrifugal force through high-speed rotation, the liquid on the membrane surface forms a high-speed turbulent or shear flow, which continuously washes the membrane surface. Under the drive of centrifugal force, the components in camellia seed oil that meet the permeation conditions pass through the membrane and enter membrane 1004, while the impurities that are trapped are removed from the membrane surface under the action of shear force, ultimately achieving efficient separation of the mixture.

[0034] The specific work involves pouring the camellia seed oil to be purified into oil tank 1. After passing through the primary screen 101, the first valve 103 is opened, and the oil enters the heating tank 2 through the first oil inlet 102. The pipeline heater 3 is started to circulate and heat the camellia seed oil. After heating is completed, the third valve 205 on the second oil inlet 204 is opened, and the camellia seed oil flows into the filter tank 9. The sixth valve 906 is opened, and the camellia seed oil flows out through the ceramic filter element 902 from the fourth oil inlet 905 to the fifth oil inlet 1001 on the centrifuge 10. After the camellia seeds enter the centrifuge 10, the centrifuge 10 is started. The motor 1002 drives the hollow shaft 1003 and the diaphragm 1004 on the shaft. Due to the rotation of the diaphragm, turbulence is generated in the camellia seed oil inside, causing high-concentration impurities to diffuse to the outside and low-concentration camellia seed oil to converge in the middle. At the same time, the camellia seed oil forms a tangential flow velocity on the surface of the polymer membrane on the diaphragm 1004. The camellia seed oil enters the diaphragm 1004 for filtration under the action of the tangential flow velocity. The camellia seed oil is guided into the hollow shaft 1003 through the guide groove 1005 in the diaphragm 1004, and finally flows out from the collection port 1006 at the lower end of the hollow shaft 1003.

[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, any modifications, equivalent substitutions, improvements, etc. made in accordance with the spirit and principles of this application should be included within the scope of protection of this utility model.
