Technical Field
[0001] This application relates to the field of edible oil filtration technology, specifically a layered filtration device for edible oil refining. Background Technology
[0002] A layered filtration device for edible oil refining is a key piece of equipment specifically designed for use in the edible oil refining process. Its core function is to remove impurities, suspended solids, colloids, free fatty acids, and other harmful or quality-affecting components from edible oils. Through its layered structural design, it achieves multi-stage, high-efficiency filtration and separation, thereby improving the quality, stability, and safety of edible oils and meeting the production standards for different grades of edible oils.
[0003] Currently, stratified filtration devices for edible oil refining generally use gravity sedimentation or vacuum filtration to filter edible oil. However, gravity sedimentation filtration is relatively slow, while vacuum filtration of edible oil is expensive and has high equipment maintenance costs. Utility Model Content
[0004] The purpose of this application is to provide a layered filtration device for edible oil refining, which solves the problems of the layered filtration devices for edible oil refining in the background art, which generally use gravity sedimentation or vacuum filtration to filter edible oil. However, gravity sedimentation filtration is slow, while vacuum filtration of edible oil is expensive and has high equipment maintenance costs.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This application provides a layered filtration device for edible oil refining, including a filter cylinder. A cylinder cover is hinged to the outer wall of the filter cylinder. Multiple sets of vertically arranged positioning strips are welded to the inner wall of the filter cylinder. An electric push rod is installed at the upper end of the cylinder cover. A pressure plate is fixedly installed at the telescopic end of the electric push rod. Multiple sets of filter paper and high-density polyurethane sponge boards are slidably connected to the inner wall of the filter cylinder. The multiple sets of filter paper and high-density polyurethane sponge boards are staggered, and the density of the multiple sets of high-density polyurethane sponge boards increases sequentially from top to bottom. A set of positioning grooves is opened in the inner wall of the pressure plate, filter paper, and high-density polyurethane sponge boards, and each set of positioning grooves corresponds to the position of the positioning strips.
[0006] By adopting the above technical solution, multiple sets of staggered high-density polyurethane sponge boards and filter paper with increasing density from top to bottom are set inside the filter cylinder. When the edible oil is inside the filter cylinder, the electric push rod drives the pressure plate to press down, and the positioning strip and positioning groove correspond to stabilize the compression filtration. Compared with traditional gravity sedimentation filtration, this filtration method uses external force to squeeze and accelerate the oil through the filter medium, thus improving filtration efficiency. Compared with vacuum filtration, it does not require a complex vacuum system. While achieving multi-stage high-efficiency filtration, it reduces equipment cost and maintenance costs, meeting the needs of edible oil refining production.
[0007] Optionally, a sealing ring is embedded in the inner wall at the upper end of the filter cartridge.
[0008] By adopting the above technical solution, the sealing ring can effectively seal the filter cartridge and the cartridge cover.
[0009] Optionally, the outer wall of the pressure plate is slidably connected to the inner wall of the cylinder cover and the filter cylinder.
[0010] By adopting the above technical solution, the outer wall of the pressure plate is slidably connected to the inner wall of the cylinder cover and the filter cylinder, which can effectively prevent the high-density polyurethane foam board from leaking pressure.
[0011] Optionally, an oil drain port is provided in the inner wall below the filter cylinder, and an oil drain pipe is welded to the lower end of the filter cylinder below the oil drain port. A valve is installed on the outer wall of the oil drain pipe.
[0012] By adopting the above technical solution, the oil drain port and oil drain pipe can be used to filter edible oil, while the valve can be used to open and close the oil drain pipe.
[0013] Optionally, the lower end of the filter cartridge is fixedly equipped with multiple sets of support legs, and the upper end of the cartridge cover is fixedly equipped with a handle.
[0014] By adopting the above technical solution, the support feet can support the filter cartridge, while the handle makes it convenient for staff to open and close the cartridge cover.
[0015] Optionally, an oil inlet is provided in the inner wall above the cylinder cover, and an oil inlet hopper is fixedly installed on the upper end of the cylinder cover above the oil inlet.
[0016] By adopting the above technical solution, the oil inlet and oil hopper can facilitate the addition of unfiltered edible oil to the inside of the filter cylinder.
[0017] Optionally, an observation window is fixedly installed on the outer wall of the filter cartridge.
[0018] By adopting the above technical solution, the observation window allows staff to easily observe the level of edible oil inside the filter cartridge.
[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application sets multiple sets of staggered high-density polyurethane sponge boards and filter paper with increasing density from top to bottom inside the filter cylinder. When the edible oil is inside the filter cylinder, the electric push rod drives the pressure plate to press down, and the positioning strip and positioning groove correspond to stabilize the compression filtration. Compared with traditional gravity sedimentation filtration, this filtration method uses external force to squeeze and accelerate the oil through the filter medium, thus improving filtration efficiency. Compared with vacuum filtration, it does not require a complex vacuum system. While achieving multi-stage high-efficiency filtration, it reduces equipment cost and maintenance costs, and meets the needs of edible oil refining production. Attached Figure Description

When the edible oil is inside the filter cylinder 1, the electric push rod 7 drives the pressure plate 6 to press down. The positioning strip 3 and the positioning groove 8 correspond to each other and can play a stable squeezing filtration role. Compared with traditional gravity sedimentation filtration, this filtration method uses external force to squeeze and accelerate the oil through the filter medium, thereby improving filtration efficiency. Compared with vacuum filtration, it does not require a complex vacuum system. While achieving multi-stage high-efficiency filtration, it reduces equipment cost and maintenance costs, and meets the needs of edible oil refining production.
[0024] In the technical solution of this application, such as Figure 2 As shown, the outer wall of the pressure plate 6 is slidably connected to the inner wall of the cylinder cover 2 and the filter cylinder 1. By slidably connecting the outer wall of the pressure plate 6 to the inner wall of the cylinder cover 2 and the filter cylinder 1, leakage of pressure in the high-density polyurethane foam board 5 can be effectively prevented.
[0025] In the technical solution of this application, such as Figure 2 As shown, an oil inlet 11 is provided in the inner wall above the cylinder cover 2. An oil hopper 9 is fixedly installed on the upper end of the cylinder cover 2 above the oil inlet 11. The oil inlet 11 and the oil hopper 9 make it convenient for staff to add unfiltered edible oil into the filter cylinder 1.
[0026] In the technical solution of this application, such as Figure 2 As shown, an oil drain port 12 is provided in the inner wall below the filter cylinder 1. An oil drain pipe 13 is welded to the lower end of the filter cylinder 1 below the oil drain port 12. A valve 14 is installed on the outer wall of the oil drain pipe 13. The oil drain port 12 and the oil drain pipe 13 can filter the edible oil, and the valve 14 can open and close the oil drain pipe 13.
[0027] In the technical solution of this application, such as Figure 2 and Figure 3As shown, a sealing ring 17 is embedded in the inner wall of the upper end of the filter cylinder 1, which can seal the filter cylinder 1 and the cylinder cover 2.
[0028] In the technical solution of this application, such as Figure 1 As shown, multiple sets of support legs 15 are fixedly installed at the lower end of the filter cylinder 1, and a handle 10 is fixedly installed at the upper end of the cylinder cover 2. The support legs 15 can support the filter cylinder 1, and the handle 10 can facilitate the opening and closing of the cylinder cover 2 by the staff. An observation window 16 is fixedly installed on the outer wall of the filter cylinder 1, which can facilitate the staff to observe the height of the edible oil inside the filter cylinder 1.
[0029] In use, the operator first opens the cylinder cover 2 and places the oil filter paper 4 and high-density polyurethane sponge board 5 into the filter cylinder 1. The positioning strip 3 positions the oil filter paper 4 and high-density polyurethane sponge board 5. Then, the cylinder cover 2 is closed, and the operator pours unfiltered cooking oil into the oil inlet 9 and oil outlet 11. The unfiltered cooking oil can flow down through the positioning groove 8. The observation window 16 allows the operator to easily observe the height of the unfiltered cooking oil. Then, the electric push rod 7 drives the pressure plate 6 to press down. The multiple sets of staggered oil filter paper 4 and high-density polyurethane sponge board 5 inside the filter cylinder 1 filter the cooking oil. The density of the polyurethane sponge board 5 increases sequentially from top to bottom. The positioning strip 3 corresponds to the positioning groove 8 on the pressure plate 6, the filter paper 4, and the high-density polyurethane sponge board 5, which can stably squeeze and filter. Under pressure, the oil passes through each layer of filter media to achieve multi-stage filtration. The filtered oil flows out from the oil outlet 12 through the oil outlet pipe 13. The oil discharge can be controlled by the valve 14. The staff can also observe the oil volume in the filter cylinder 1 through the observation window 16. Multiple sets of high-density polyurethane sponge boards 5 need to be set up to facilitate the replacement of the high-density polyurethane sponge boards 5 inside the filter cylinder 1, thereby facilitating the cleaning and drying of the replaced high-density polyurethane sponge boards 5 by the staff.
