Description

Technical Field

[0001] This utility model relates to the technical field of oil filtration equipment, and in particular to a multi-stage filtration and purification equipment for vegetable oil. Background Technology

[0002] In the production and refining of vegetable oils, multi-stage filtration is a common purification method. By progressively reducing the pore size of the filter, impurities in the oil can be effectively removed, improving the purity of the vegetable oil. However, existing multi-stage filtration equipment suffers from difficulties in cleaning oil residue during practical use. For example, traditional filtration equipment typically uses fixed filter screens or filter cloths. As the oil flows through the filter layer, impurities gradually accumulate on the filter surface, leading to a decrease in filtration efficiency, affecting the normal flow of oil, and requiring frequent shutdowns for manual disassembly and cleaning, thus reducing production efficiency.

[0003] Therefore, there is an urgent need for a multi-stage filtration vegetable oil purification device that can automatically clean and efficiently discharge the filtered oil residue, so as to improve filtration efficiency, reduce manual maintenance costs, and ensure the production quality of vegetable oil. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage filtration vegetable oil purification device that can automatically clean the filtered oil residue regularly, thereby improving filtration efficiency, reducing manual maintenance costs, and ensuring the production quality of vegetable oil.

[0021] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0022] like Figures 1 to 4As shown, the multi-stage filtration vegetable oil purification device of this utility model includes a filter tank 1, a detachable sealing cover 2 on the top of the filter tank 1, an oil inlet 3 on the sealing cover 2, and an oil outlet at the bottom of the filter tank 1. Preferably, a conical oil outlet chamber 4 is provided at the bottom of the filter section 6, with the oil outlet located at the bottom of the oil outlet chamber 4. An oil pump 5 is installed on the oil outlet at the bottom of the oil outlet chamber 4 to facilitate oil filtration and delivery. Inside the filter tank 1, multiple filter sections 6 with progressively decreasing diameter filter holes 14 are arranged at intervals from top to bottom to achieve graded filtration of the oil. A rotating shaft 8 driven by a motor 7 is rotatably connected to the filter section 6. The motor 7 is located on top of the sealing cover 2. A cleaning rod 9 with bristles is mounted on the rotating shaft 8, contacting the filter surface of the filter section 6 to ensure cleaning effectiveness. A drain hole 10 is provided on the filter section 6. A sealing plate 11 is mounted on the cleaning rod 9. Initially, the sealing plate 11 covers and seals the drain hole 10. Each drain hole 10 is connected to a material guide channel 13 located outside the filter tank 1 via a drain pipe 12. During operation, the motor 7 is periodically started to drive the rotating shaft 8, which in turn drives the cleaning rod 9 to sweep the oil residue filtered out by the filter section 6 to the drain hole 10, from which it flows into the drain pipe 12. Finally, the oil residue is discharged through the material guide channel 13. The entire process requires no direct manual intervention, reducing labor costs and improving production efficiency. In this embodiment, cleaning can be carried out simultaneously with cleaning fluid. The cleaning fluid is introduced from the oil inlet 3 to clean the oil stains on the filter section 6. The cleaning rod 9 cleans the oil residue on the surface of the filter section 6 and the oil adhering to the filter section 6. After the cleaning fluid is used, clean water is introduced into the filter tank 1 to rinse the inside of the equipment, ensuring that the cleanliness of the equipment after use meets the hygiene standards.

[0023] In this embodiment, the drain hole 10 is located near the inner wall of the bottom of the filter section 6, i.e., at the edge of the filter section 6, to reduce the adverse effects on filtration. The filter section 6 includes a sleeve 6-1 that extends vertically, and a filter screen 6-2 is disposed inside the sleeve 6-1. The bristles on the cleaning rod 9 are in contact with the surface of the filter screen 6-2. Preferably, the filter screen 6-2 has an upwardly protruding cone structure in the middle, and the rotating shaft 8 is rotatably disposed in the middle of the cone structure. An annular receiving plate 6-3 is disposed between the bottom of the cone structure and the sleeve 6-1, and the drain hole 10 is disposed on the receiving plate 6-3. At this time, the cleaning rod 9 is disposed radially along the receiving plate 6-3 and the slope of the cone structure, and the top of the cleaning rod is connected to the connecting sleeve on the rotating shaft. Figure 3 As shown. The conical structure increases the filtration area and guides the filtered oil residue to fall onto the receiving plate 6-3 below, so that it can be discharged through the drain hole 10. At the same time, the conical structure provides a slope for the oil residue to flow during operation, which reduces the obstruction caused by the oil residue to the filter to a certain extent.

[0024] The surface of the receiving plate 6-3 is smooth, and preferably it is provided with filter holes 14. A mesh plate 15 is provided inside the filter holes 14 to filter the oil dripping onto the receiving plate 6-3 and the oil entrained in the oil sludge, thereby reducing the oil content when the oil sludge is discharged and reducing the waste of oil. The top of the mesh plate 15 is flush with the top of the receiving plate 6-3 to avoid obstructing the movement of the sealing plate 11, and also to facilitate the cleaning of oil sludge adhering to the mesh plate 15.

[0025] Furthermore, a first flange 16 is coaxially mounted on the outer side of the sleeve 6-1, and a second flange 17 is coaxially mounted inside the filter tank 1. The first flange 16 and the second flange 17 are connected by bolts to achieve fixed installation of the sleeve 6-1 inside the filter tank 1. The outer diameter of the lower first flange 16 is smaller than the inner diameter of the upper second flange 17. This allows the lower filter section 6 to be removed from the hole in the middle of the upper second flange 17 during subsequent disassembly and maintenance, facilitating the installation and disassembly of the multi-stage filter section 6. The opening area at the top of each stage of the filter section 6 is not affected, that is, the opening area at the top of the sleeve 6-1 is not affected; only the diameter of the flange needs to be slightly adjusted to ensure smooth connection between the upper and lower layers of filtered oil.

[0026] Furthermore, the drain hole is positioned higher than the point where the drain pipe 12 connects to the material guide channel 13. This allows the drain pipe 12 to be arranged at an angle between the drain hole and the material guide channel 13, ensuring that the oil sludge smoothly enters the material guide channel 13. A collection box 18 is installed at the bottom of the material guide channel 13 to collect the discharged oil sludge for convenient subsequent centralized processing.

[0027] In operation, filtered oil is input through the oil inlet 3. After passing through multiple filtration stages, the oil enters the oil discharge chamber 4 and is then pumped out by the oil pump 5 to the next stage. When cleaning of the filter section 6 is required, the motor 7 is started to drive the rotating shaft 8 to rotate. The cleaning rod 9 cleans the surface of the filter screen 6-2, and the cleaned oil residue is smoothly discharged from the drain hole 10 and finally collected in the sludge collection box. The entire process requires no direct manual intervention, reducing labor intensity, saving labor costs, and ensuring filtration efficiency.
