Description

Technical Field

[0001] The invention relates to the technical field of edible oil processing, in particular to a filtering device for edible oil processing. Background Art

[0002] Edible oil is an indispensable raw material in food processing. It mainly comes from animal or vegetable oils and remains liquid at room temperature. Due to the diversity of raw materials, differences in processing technology and different pursuits of quality, most edible oils circulating on the market are vegetable oils.

[0003] The pressing method, as the leader in oil-making technology, has won wide recognition by virtue of its technical characteristics of directly squeezing and separating oil from oil materials with physical pressure. In this process, the use of any chemical additives is completely abandoned, thus ensuring the safety, hygiene and environmental friendliness of the product. At the same time, the pressing method can also retain the natural nutrients of the oil to the maximum extent and prevent it from being damaged.

[0004] However, in the edible oil pressing production process, a problem that cannot be ignored is that the fine debris in the raw materials is easily mixed into the oil, which affects the quality of the edible oil to a certain extent. Therefore, fine filtering of the pressed edible oil to remove these impurities and improve the quality of the edible oil has become a crucial process. Unfortunately, the common edible oil filtering equipment on the market often has the problem of impurity clogging after long-term use, resulting in a significant decrease in filtration efficiency, and even the need to interrupt the filtration process for cleaning, which undoubtedly increases production costs and reduces production efficiency. To this end, we propose a filtering device for edible oil processing. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1-Figure 13The present invention provides a technical solution: a filtering device for processing edible oil, comprising a box body 1, wherein the upper and lower ends of the box body 1 are respectively provided with an oil inlet and an oil outlet, and further comprising a movable filtering mechanism 2 movably arranged in the box body 1, which can change its shape during filtering so that the edible oil passes through an unblocked filtering area, a collecting box 3 is slidably arranged in the box body 1, and the edible oil filtered by the movable filtering mechanism 2 is collected in the collecting box 3, and the collecting box 3 is transmission-connected with the movable filtering mechanism 2, and then the edible oil gradually accumulates in the collecting box 3, causing the movable filtering mechanism 2 to change its shape when it moves, and a guide plate 4 is arranged at the bottom of the movable filtering mechanism 2 for collecting and guiding the filtered edible oil to avoid the edible oil being directly left after filtering and generating bubbles, and an air pressure component 5 is also arranged inside the box body 1, and the air pressure component 5 is transmission-connected with the collecting box 3, and the air pressure component 5 is communicated with the inside of the guide plate 4, and collecting plates 6 are also arranged on both sides of the inside of the box body 1.

[0039] The movable filtering mechanism 2 includes two mounting frames 21 whose ends are rotatably connected to each other by a rotating shaft, and the other ends of the two mounting frames 21 are each provided with a movable shaft 22. A movable groove 23 is provided on the inner side of the box body 1, and the movable shaft 22 is movably arranged in the movable groove 23, so that when the mounting frame 21 rotates, space for movement is reserved for its two ends. A movable groove 24 is also provided on the inner side of the box body 1, and the rotating shafts at the intersecting ends of the two mounting frames 21 are movably arranged in the movable groove 24. A filter screen 25 is provided on the upper part of the two mounting frames 21. In the initial state, the two mounting frames 21 are V-shaped. After the collection box 3 gradually drives them to rotate, an inverted V-shape will be formed between the two mounting frames 21. In the process of this shape change, the contact area between the edible oil and the filter screen 25 will also change, thereby ensuring that the residue on the filter area is always kept in a small state, ensuring smoothness in the entire filtering process.

[0040] Both ends of the filter 25 are fixedly connected with a magnetic strip 7, and a magnetic strip 2 8 that is attracted to the magnetic strip 7 is fixedly arranged on the inner side of the box 1. The two ends of the filter 25 can be installed in the box 1 through magnetic attraction, and it is very convenient to replace. Limit rods 9 for limiting the filter 25 are fixedly arranged on the two installation frames 21. Since the two installation frames 21 will rotate, in order to ensure that the filter 25 is always in contact with the installation frame 21, a limit rod 9 is arranged on the installation to limit the movement of the filter 25 on the installation frame 21.

[0041] The movable groove 24 includes a straight segment 1 241, an arc segment 242 and a straight segment 243. The rotating shafts at the intersection ends of the two mounting frames 21 are movably arranged in the straight segment 1 241, and a pull rope 10 is fixedly connected to the rotating shaft. The end of the pull rope 10 bypasses the arc segment 242 and enters the straight segment 243 and is fixedly connected to the collection box 3. Then, when the collection box 3 descends, the pull rope 10 can drive the rotating shaft to move upward, so that the two mounting frames 21 rotate relative to each other. Therefore, as the filtering proceeds, since the two mounting frames 21 are V-shaped at the beginning, the bottom area of ​​the V-shape where the filter screen 25 is located has ash residues as the filtering is carried out, resulting in a full filtering effect. Then, when the edible oil gradually accumulates in the collection box 3, it gradually becomes heavier, and then moves downward in the box body 1, driving the mounting frame 21 to rotate, so that the filtering area where the edible oil contacts the filter screen 25 changes, thereby ensuring the filtering efficiency.

[0042] Two guide plates 4 are provided and are fixedly connected to the mounting frames 21 on both sides respectively. A plurality of guide grooves 11 are opened on the guide plate 4. The filtered edible oil is collected into the guide grooves 11 and then flows into the collecting box 3, which plays a collecting role, reduces the generation of bubbles in the filtered edible oil, and ensures the quality of the oil.

[0043] The pneumatic assembly 5 includes a fixed cylinder 51 fixedly arranged on the inner side of the box body 1, a piston 52 is slidably arranged in the fixed cylinder 51, a push rod 53 is arranged at the bottom of the piston 52 and passes through one end of the fixed cylinder 51, a support spring 54 is arranged on the piston 52, and both ends of the support spring 54 are respectively connected to the fixed cylinder 51 and the piston 52, a hose 55 is arranged on the top of the fixed cylinder 51, and the end of the hose 55 is connected to the guide plate 4.

[0044] A winding rod 56 is fixedly provided on the inner wall of the box body 1, and a pull rope 57 is fixedly connected to the bottom end of the top rod 53. The end of the pull rope 57 passes around the winding rod 56 and is fixedly connected to the collection box 3. When the collection box 3 descends, the top rod 53 will be driven to move upward. When the top rod 53 moves upward, the air in the fixed tube 51 will be squeezed into the cavity inside the guide plate 4.

[0045] The guide plate 4 is provided with a plurality of air holes 12, and the plurality of air holes 12 are all located on one side of the guide groove 11. A cavity is provided inside the guide plate 4, and the air holes 12 are all connected to the cavity. A block 13 is movably provided in the air hole 12, and an elastic telescopic rod 14 is provided at the bottom of the block 13. The bottom end of the elastic telescopic rod 14 is fixedly connected to the bottom of the cavity, and a side plate 15 is fixedly provided on the outer side of the movable end of the elastic telescopic rod 14. A driving rod 16 is slidably provided in the cavity, and a plurality of inclined blocks 17 are fixedly provided on the driving rod 16. When the driving rod 16 moves, it can drive the inclined block 17 to squeeze the side plate 15, so that the elastic telescopic rod 14 drives the block 13 to move upward to expose the air hole 12. A plurality of strong magnets are embedded in the inner side of the box body 1, and the end of the driving rod 16 is made of antimagnetic material that can repel the strong magnet;

[0046] As the collecting box 3 gradually moves, the air in the fixed cylinder 51 is squeezed into the cavity in the guide plate 4, increasing the internal air pressure. However, it cannot be released due to the block 13. When the collecting box 3 collects enough edible oil, it will eventually drive the two mounting frames 21 to form an inverted V shape. At this time, the strong magnet will repel the driving rod 16 to move it, and the inclined block 17 will squeeze the side plate 15, so that the elastic telescopic rod 14 will drive the block 13 to move up to expose the pore 12, and the air pressure will be released. The air is ejected from the pore 12, so that the residue remaining on the filter screen 25 is rushed to the collecting plate 6 by the air flow, thereby cleaning the filter screen 25 without stopping the machine. When there is enough residue on the collecting plate 6, it needs to be cleaned once. In order to ensure the collection effect of the collecting plate 6, bristles can be set on the surface. The residue is easy to adhere to the bristles and the edible oil can be left along the gaps between the bristles.

[0047] A telescopic tube 18 is provided at the bottom of the collecting box 3, and the bottom end of the telescopic tube 18 is connected to the oil outlet of the box body 1. A solenoid valve is provided inside the telescopic tube 18, and a contact switch is provided on the inner side of the box body 1. When the collecting box 3 moves downward to touch the contact switch, the solenoid valve opens the telescopic rod for a period of time to allow the edible oil in the collecting box 3 to flow out, and then the solenoid valve is closed, and the collecting box 3 is reset, and the mounting frame 21 and the piston 52 are reset to form a filtering cycle.

[0048] In summary, edible oil enters the box body 1 from the oil inlet and is filtered by the movable filtering mechanism 2. The movable filtering mechanism 2 is composed of two mounting frames 21 that are rotatably connected to each other through a rotating shaft. A filter screen 25 is arranged on the mounting frame 21. In the initial state, the two mounting frames 21 are V-shaped, so that the bottom area of ​​the filter screen 25 becomes the main filtering area. As the filtering proceeds, edible oil gradually accumulates in the collection box 3 and moves downward. The rotating shaft of the mounting frame 21 is driven to rotate by the pull rope 10, so that the two mounting frames 21 are gradually transformed into an inverted V shape, thereby changing the contact area between the edible oil and the filter screen 25 to ensure the filtering effect.

[0049] At the same time, as the collection box 3 moves downward, the piston 52 in the fixed cylinder 51 is driven upward by the pull rope 57, and the air in the fixed cylinder 51 is squeezed into the cavity inside the guide plate 4. When the collection box 3 collects enough edible oil, the strong magnet repels the driving rod 16 to move it, and the inclined block 17 squeezes the side plate 15, so that the elastic telescopic rod 14 drives the blocking block 13 to move upward to expose the air hole 12, and the air pressure is released, and the air is ejected from the air hole 12, and the residue remaining on the filter screen 25 is rushed to the collection plate 6;

[0050] When the collecting box 3 moves downward and triggers the contact switch, the solenoid valve opens the telescopic tube 18 for a period of time, allowing the edible oil in the collecting box 3 to flow out to the oil outlet. Then the solenoid valve is closed, the collecting box 3 is reset, and the mounting frame 21 and the piston 52 are also reset to complete a filtering cycle. During the whole process, the movable filtering mechanism 2, the air pressure assembly 5 and the collecting box 3 cooperate with each other to achieve efficient and automatic edible oil filtering.

[0051] Example 2: Example 2 has the same main structure as Example 1, except that the collecting plate 6 is movably installed on the inner side of the box body 1, and the collecting plate 6 can be installed in the box body 1 by magnetic attraction or snap connection, thereby facilitating the cleaning and replacement of the collecting plate 6.
