Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible oil technology, and in particular to a bag filter for edible oil production. Background Technology
[0002] Bag filters are a type of multi-purpose filtration equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed operation, and strong applicability. Bag filters are a new type of filtration system. Inside the bag filter, the filter bag is supported by a metal mesh basket. Liquid flows in through the inlet, is filtered by the filter bag, and flows out through the outlet. Impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used. Special bag filters are also used in the production of edible oil to filter impurities from the edible oil. Existing bag filters have limited functionality. When filtering cooking oil, a layer of grease tends to adhere to the filter wall, making it difficult to completely remove and requiring a long time to drain. This time-consuming process reduces filtration efficiency. Furthermore, the filter bags in bag filters tend to fold or close at the bottom due to the impact of the oil during filtration, further reducing their filtration efficiency. Some models also require additional positioning frames, complicating the installation process of the filter bags.
[0003] Therefore, it is necessary to provide a new bag filter for edible oil production to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a bag filter for edible oil production.
[0005] The bag filter for edible oil production provided by this utility model includes: Filter cartridge, and A cover is fitted onto the filter cylinder, and a filter bag is fixedly installed at the bottom of the cover. Several equidistant collars are fixedly fitted onto the outer surface of the filter bag, and the upper and lower surfaces of the collars are respectively provided with arc grooves and elastic protrusions. The outer ring wall of the cylinder cap is fixedly fitted with an elastic pleated telescopic airbag, and the outer wall of the elastic pleated telescopic airbag is fixedly fitted with several elastic plastic scraper blades that are evenly distributed vertically.
[0006] Preferably, the filter cylinder has an installation cavity at its opening for placing the cylinder cover, and a filter arc surface is provided between the installation cavity and the filter chamber inside the filter cylinder.
[0007] Preferably, the elastic convex ring is interference-fitted with the arc-shaped groove, and the aperture of the mounting cavity is larger than the aperture of the filter chamber.
[0008] Preferably, the top of the cylinder cover is provided with an oil pipe interface communicating with the filter bag, and both sides of the cylinder cover are fixedly fitted with limit rings.
[0009] Preferably, locking rings are fixedly fitted on both sides of the top of the filter cylinder, and an insertion rod is inserted into the locking ring.
[0010] Preferably, the bottom of the filter cartridge is equipped with an oil drain valve and a support leg for supporting the filter cartridge.
[0011] Preferably, a handle is fixedly installed on the top of the cylinder cover.
[0012] Compared with related technologies, the bag filter for edible oil production provided by this utility model has the following beneficial effects: When not in use, the filter bag of this utility model can be folded up. Specifically, the elastic protruding ring at the bottom of the upper sleeve ring is pressed into the arc-shaped groove of the lower sleeve ring. Due to the interference fit between the elastic protruding ring and the arc-shaped groove, adjacent sleeve rings can be folded up, thereby reducing the volume of the filter bag and making it easy to handle and store. When in use, they can be separated. On the other hand, the multiple sleeve rings on the outside of the filter bag can help to shape the filter bag when filtering oil, so that the filter bag is cylindrical after being stretched out. This avoids the phenomenon of the bottom of the bag closing or folding due to the external oil pressure, thereby reducing the problem of reduced oil filtration efficiency. After the operator pushes down the cylinder cover, the elastic plastic scraper can slide the grease adhering to the inner wall of the filter cylinder to the bottom of the cylinder. The grease layer is scraped off and flows out quickly, thereby improving the oil discharge efficiency and saving time. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0017] Please see Figures 1 to 4 This utility model provides a bag filter for edible oil production, which includes: a filter cylinder 1, a cylinder cover 2, and a filter bag 3.
[0018] In the embodiments of this utility model, please refer to Figures 1 to 4 The filter cylinder 1 is covered with a cylinder cover 2, and the filter cylinder 1 has an installation cavity 1a for placing the cylinder cover 2 at the cylinder opening. A filter arc surface 11 is provided between the installation cavity 1a and the filter chamber 1b inside the filter cylinder 1. The aperture of the installation cavity 1a is larger than the aperture of the filter chamber 1b. A filter bag 3 is fixedly installed at the bottom of the cylinder cover 2. Several equidistantly distributed sleeve rings 4 are fixedly fitted on the outer bag surface of the filter bag 3. The upper and lower ring surfaces of the sleeve rings 4 are respectively provided with arc grooves 4a and elastic protruding rings 41, and the elastic protruding rings 41 and arc grooves 4a are interference fit.
[0019] It should be noted that when the filter bag 3 is not in use, it can be folded up. Specifically, the elastic protruding ring 41 at the bottom of the upper sleeve ring 4 is pressed into the arc-shaped groove 4a of the lower sleeve ring 4. Since the elastic protruding ring 41 and the arc-shaped groove 4a are interference-fitted, adjacent sleeve rings 4 can be folded up, thereby reducing the volume of the filter bag 3 and making it easy to handle and store. When in use, they can be separated. On the other hand, the multiple sleeve rings 4 on the outside of the filter bag 3 can help to shape the filter bag 3 when it is filtering oil, so that the filter bag 3 is cylindrical after being stretched out. This avoids the phenomenon of the bottom of the bag closing or folding due to the external oil pressure, thereby reducing the problem of reduced oil filtration efficiency of the filter bag 3.
[0020] In the embodiments of this utility model, please refer to Figures 1 to 4The outer ring wall of the cylinder cover 2 is fixedly fitted with an elastic pleated telescopic airbag 5, and the outer wall of the elastic pleated telescopic airbag 5 is fixedly fitted with several elastic plastic oil scraper blades 51 distributed vertically and vertically at equal intervals. The top of the cylinder cover 2 is provided with an oil pipe interface 21 that communicates with the filter bag 3, and the two sides of the cylinder cover 2 are fixedly fitted with limit rings 22. The two sides of the top of the filter cylinder 1 are fixedly fitted with locking rings 13, and the locking rings 13 are fitted with insertion rods 6. The bottom of the filter cylinder 1 is equipped with an oil drain valve 12 and a support leg 14 for supporting the filter cylinder 1, and the top of the cylinder cover 2 is fixedly installed with a handle 7.
[0021] It should be noted that when installing the filter bag 3 inside the filter cylinder 1, the filter bag 3 is unfolded and placed into the filter chamber 1b from the opening of the filter cylinder 1. The cylinder cover 2 is directly closed into the installation cavity 1a, and the elastic plastic scraper 51 slides down along the installation cavity 1a. Since the cylinder cover 2 is provided with an elastic pleated telescopic airbag 5, the elastic pleated telescopic airbag 5 contracts after being compressed until the limiting ring 22 on the cylinder cover 2 corresponds to the locking ring 13 on the filter cylinder 1. Then, the insertion rod 6 is inserted through the limiting ring 22 to position it. Since the elastic pleated telescopic airbag 5 is compressed, the elastic plastic scraper 51 can seal the opening of the filter cylinder 1. After the oil filtration is complete, push the handle 7 to slide the cover 2 downward into the filter cylinder 1. At this time, a filter arc surface 11 is provided between the mounting cavity 1a and the filter chamber 1b inside the filter cylinder 1. The aperture of the mounting cavity 1a is larger than the aperture of the filter chamber 1b. Therefore, when the cover 2 is pressed down, the elastic pleated telescopic air bag 5 continuously contracts until the elastic plastic scraper 51 slides into the filter chamber 1b. After the operator pushes the cover 2 up and down several times, the elastic plastic scraper 51 can slide the grease attached to the inner wall of the filter cylinder 1 to the bottom of the cylinder. The grease layer will be scraped off and flow out quickly, thereby improving the oil output efficiency and saving time. Afterward, the filter bag 3 can be removed after pulling out the cover 2.
[0022] The working principle of the bag filter for edible oil production provided by this utility model is as follows: When the filter bag 3 is not in use, it can be folded up. Specifically, the elastic protruding ring 41 at the bottom of the upper sleeve ring 4 is pressed into the arc-shaped groove 4a of the lower sleeve ring 4. Since the elastic protruding ring 41 and the arc-shaped groove 4a are interference fit, the adjacent sleeve rings 4 can be folded up, thereby reducing the volume of the filter bag 3 and making it easy to handle and store. When in use, they can be separated. On the other hand, the multiple sleeve rings 4 on the outside of the filter bag 3 can help to shape the filter bag 3 when it is filtering oil, so that the filter bag 3 is cylindrical after being stretched out. This avoids the phenomenon of the bottom of the bag closing or folding due to the external oil pressure, thereby reducing the problem of reduced oil filtration efficiency of the filter bag 3. When installing the filter bag 3 inside the filter cylinder 1, the filter bag 3 is unfolded and placed into the filter chamber 1b from the opening of the filter cylinder 1. The cylinder cover 2 is directly closed into the installation cavity 1a, and the elastic plastic scraper 51 slides down along the installation cavity 1a. Since the cylinder cover 2 is provided with an elastic pleated telescopic airbag 5, the elastic pleated telescopic airbag 5 contracts after being compressed until the limiting ring 22 on the cylinder cover 2 corresponds to the locking ring 13 on the filter cylinder 1. Then, the insertion rod 6 is inserted through the limiting ring 22 to position it. Since the elastic pleated telescopic airbag 5 is compressed, the elastic plastic scraper 51 can seal the opening of the filter cylinder 1. After the oil filtration is complete, push the handle 7 to slide the cover 2 downward into the filter cylinder 1. At this time, a filter arc surface 11 is provided between the mounting cavity 1a and the filter chamber 1b inside the filter cylinder 1. The aperture of the mounting cavity 1a is larger than the aperture of the filter chamber 1b. Therefore, when the cover 2 is pressed down, the elastic pleated telescopic air bag 5 continuously contracts until the elastic plastic scraper 51 slides into the filter chamber 1b. After the operator pushes the cover 2 up and down several times, the elastic plastic scraper 51 can slide the grease attached to the inner wall of the filter cylinder 1 to the bottom of the cylinder. The grease layer will be scraped off and flow out quickly, thereby improving the oil output efficiency and saving time. Afterward, the filter bag 3 can be removed after pulling out the cover 2.
