Description

Technical Field

[0001] This application relates to the technical field of supporting equipment for vegetable oil production, and in particular to a filtering and purifying device for vegetable oil production. Background Art

[0002] Vegetable oil is an essential basic material in the existing living diet structure. In the production process of vegetable oil, it is necessary to extract oil components from oil crops through means such as pressing or grinding. In large-scale production, there are still a certain amount of debris and other particulate matters mixed in the raw materials. Therefore, a filtering operation is also required during the production of oil materials. In the existing filtering operation, a relatively dense sieve is often used for screening and filtering. Due to the certain viscosity of the oil liquid, the filtering process will be relatively slow. In order to improve the purification degree of filtering, multiple layers of sieves are used for multiple filtrations, which results in a slower filtering speed and an increase in the process, greatly affecting the production efficiency. Some existing devices such as pressure filtration equipment and high-speed centrifugal filtration equipment can improve the filtering speed, but due to the high procurement cost of their equipment and the high professional requirements for the operation process, they are not suitable for small and micro enterprises. Therefore, a more practical filtering and purifying device needs to be set up to solve these existing problems. Summary of the Invention

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] To more clearly understand the technical solutions shown in the embodiments of the present application, first, the working principle of the existing filtration and purification for vegetable oil production will be introduced.

[0024] In the existing purification process of vegetable oil, filters with a certain size and filter paper are often used for filtration. However, due to the viscosity of the oil, the filtration speed is slow, resulting in a reduction in production efficiency. Although some existing centrifugal and pressurized filtration devices can improve the filtration speed while ensuring the filtration effect, the cost of such devices is relatively high and not suitable for the actual needs of small enterprises. Therefore, it is necessary to improve the existing such devices, provide a new type of filtration structure to meet the existing filtration requirements, and at the same time be able to accelerate the filtration efficiency, and then the design scheme of the present application is proposed.

[0025] Please refer to Figure 1 and Figure 2 , which is a filtration and purification device for vegetable oil production disclosed in the embodiments of the present application, including: connecting base 1, outer housing 2, connecting bushing 3, rotating shaft 4, bottom plate 5, outer filter housing 6, inner filter cylinder 7, liquid outlet 8, transmission wheel 9, driving motor 10, driving wheel 11, belt 12, upper cover plate 17, mounting sleeve 18, and liquid inlet conduit 19. A through hole is provided in the middle of the connecting base 1. The outer housing 2 is fixedly connected to the upper surface of the connecting base 1. The lower end of the connecting bushing 3 is fixedly connected to the lower surface at the middle position inside the outer housing 2. The rotating shaft 4 is rotatably connected to the middle of the connecting bushing 3. The lower end of the rotating shaft 4 passes through the lower surface of the connecting base 1. The appearance of the bottom plate 5 is circular, and the middle position of the bottom plate 5 is fixedly connected to the shaft body of the rotating shaft 4 near the upper end. The lower end of the outer filter housing 6 is fixedly connected to the periphery of the bottom plate 5. The diameter of the lower end of the outer filter housing 6 is larger than that of the upper end. The inner filter cylinder 7 is arranged inside the outer filter housing 6. The lower end of the inner filter cylinder 7 is fixedly connected to the upper end of the rotating shaft 4. The lower end of the inner filter cylinder 7 is in contact with the upper surface of the bottom plate 5. The liquid outlets 8 are arranged in an annular array at the edge position of the lower end of the outer housing 2. The transmission wheel 9 is fixedly connected to the lower end of the rotating shaft 4. The driving motor 10 is fixedly connected to the lower surface on one side of the connecting base 1. The driving wheel 11 is fixedly connected to the end of the output shaft of the driving motor 10. The two ends of the belt 12 are respectively in transmission connection with the driving wheel 11 and the transmission wheel 9. The upper cover plate 17 is cooperatively connected to the upper end of the outer housing 2. The mounting sleeve 18 is fixedly connected to the middle position of the upper cover plate 17. The liquid inlet conduit 19 is cooperatively connected to the middle of the mounting sleeve 18. The lower end of the liquid inlet conduit 19 extends into the inner filter cylinder 7.

[0026] Specifically, the provided connection base 1 is used to provide a support and connection position. The upper end of the provided outer shell 2 is open. The outer shell 2 can be used to collect the filtered and purified oil, and then discharge it through the liquid outlet 8 at the lower end. The provided connection bushing 3 mainly adopts a bearing structure, which can support heavy objects up and down, and at the same time ensure the stable rotation of the internal connecting rotating shaft 4. The edge position of the provided bottom plate 5 is bent downward, increasing the area of edge connection and fixation, and can firmly connect the outer filter shell 6. The outer filter shell 6 adopts a trumpet-shaped structure with a small upper diameter and a large lower diameter, and holes for starting the filtering function are provided at its edge. In actual use, filter screens, filter papers and other components can also be laid on its inner wall according to needs to further increase the filtering degree. The provided inner filter cylinder 7 is connected inside the outer filter shell 6, and then when rotating, the oil can be thrown out from the holes around it to realize the process of primary filtering. The lower end of the inner filter cylinder 7 is fixed to the upper end of the rotating shaft 4 to make the connection more stable. The provided driving motor 10 can convert electrical energy into mechanical energy and then drive the belt 12 through the driving wheel 11, so as to drive the transmission wheel 9, and then drive the rotating shaft 4 to rotate. The diameter of the provided driving wheel 11 is larger than that of the transmission wheel 9, which can increase the rotation speed of the rotating shaft 4 during the rotation process, and then make it have a higher centrifugal force. The provided driving motor 10 is selected as a motor that can adjust the speed, which can meet the filtering requirements of different oils. The provided upper cover plate 17 can close the upper end of the outer shell 2, forming a relatively closed cavity inside the outer shell 2, which is convenient for collecting oil and avoiding splashing. The inside of the provided mounting sleeve 18 can be connected with the liquid inlet conduit 19 in a matching manner to keep its position stable and facilitate the pouring of external oil. Regarding the depth of the liquid inlet conduit 19 extending into the inner filter cylinder 7, it is preferably extended into the inner filter cylinder 7 by one-third to one-half of the depth, which is convenient for the entry of oil and better avoids the splashing of oil. The oil passes through the inner filter cylinder 7 and the outer filter shell 6 to achieve filtering with different diameters. The oil residues are retained inside and are disassembled and removed after filtering. At this time, the filter residues are relatively dry and convenient for operation. This structure can achieve a faster and better oil filtering and purification effect, and the manufacturing cost of the equipment is relatively low, with good practicability, is more easily accepted by people, and has good application prospects.

The set limit slots 15 and limit blocks 16 can make the installation of the inner filter cartridge 7 on the bottom plate 5 more rapid, and at the same time directly transfer the rotational force of the bottom plate 5 to the inner filter cartridge 7, avoiding the phenomenon of damage and deformation in the middle caused by only the center of the inner filter cartridge 7 being stressed, helping to maintain the smoothness during use and ensuring the filtration and purification quality.

The set mounting holes 24 can connect the backing plate 23 to the ground or other support planes, ensuring the fixed position during use without movement.

[0037] Please refer toFigure 1 , as another specific implementation manner provided by the application, it further includes a recessed portion 25, and the recessed portion 25 is arranged on the outer surface of one side of the liquid inlet conduit 19.

[0038] Specifically, the arrangement of the recessed portion 25 can discharge the air inside the outer casing 2, which is convenient for ensuring the balance of the internal and external air pressures and avoiding blockage during the filling of the oil.
