Description

Technical Field

[0001] The utility model belongs to the technical field of fluid filtration, in particular to a novel pleated filter element. Background Art

[0002] The pleated filter element is a device used for filtering high-viscosity media. It uses metal fiber sintered filter felt and metal woven wire mesh. The pleated filter element has a large area, strong dirt storage capacity, high porosity, strong air permeability, low pressure difference, excellent strength, high temperature resistance, corrosion resistance, good regeneration, and can be reused repeatedly. Therefore, it is widely used in the filtration of polymer melts, high-temperature gases, steam, high-temperature liquids, and viscous liquids in the production of polyester, filaments, staple fibers, and films. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN202962047U discloses a metal sintered mesh pleated filter element, wherein the head of the sintered mesh cylinder is provided with an upper end cover, the tail of the sintered mesh cylinder is provided with a lower end cover, the upper end cover and the lower end cover are respectively provided with connecting holes, the sintered mesh cylinder is continuously distributed in a wave shape, and the sintered mesh cylinder is provided with evenly distributed filter holes. The pleated filter element increases the contact area with the fluid during filtration and improves the filtration efficiency by repeatedly folding the filter screen. However, in actual use, the filter screen also has many dead corners that are easily blocked by impurities due to the large number of folded positions. When cleaning regularly, the impurities in the dead corners are difficult to be quickly removed, and the cleaning operation is relatively time-consuming and laborious.

[0004] During the use of the filter element, when the fluid flows from the inside to the outside or from the outside to the inside for filtration, it often causes a certain amount of pressure on the filter element. In order to prevent the filter element from deformation due to long-term use, a support frame is usually required on the outside of the filter element for support. However, the structure of the pleated filter element is relatively special. Setting a support frame that fits completely to the filter element will greatly increase the cost of the pleated filter element, and not setting a support frame will lead to a shortened service life of the pleated filter element. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of pleated filter element, which solves the problem of many dead corners in the pleated filter element and difficulty in completely removing impurities in the dead corners during cleaning by folding a supporting net, an upper supporting frame and a scraper. The pleated filter element has a large surface area. Setting a supporting frame that is completely in contact with the filter element will greatly increase the cost of the pleated filter element, while not setting a supporting frame will lead to a shortened service life of the pleated filter element.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a novel pleated filter element, comprising a pleated support net, an upper support frame and a scraper, wherein a pleated filter element body is sleeved on the inner side of the pleated support net, an upper support frame is clamped and fixed on the top of the folded support net, a lower support frame is clamped and fixed on the bottom of the folded support net, a scraper is slidably clamped in the pleated filter element body, a pull rope is clamped and fixed on the top of the scraper, and an automatic winding component is arranged at the bottom of the scraper;

[0008] By folding the support net, the tip and tail of the fin of the pleated filter element body can be stretched, thereby increasing the pulling force on each fin, ensuring the stability of the fin during use, and avoiding deformation of the filter element after long-term use. When cleaning the pleated filter element, the pull rope can be pulled to drive the scraper to slide in the pleated filter element body to scrape off impurities blocking the pleated filter element body, and after the pulling force on the pull rope is released, the scraper can be reset under the pulling force of the automatic winding component. The cleaning operation is simple and convenient, reducing the labor intensity of the staff.

[0009] Furthermore, a plurality of groups of first elastic support blocks and a plurality of second elastic support blocks are arranged inside the folded support net, the first elastic support blocks are attached to both sides of the inside and outside of the folded filter element body, and the second elastic support blocks are pressed and attached between the folded filter element body and the folded support net;

[0010] The first elastic support block can position and support the inside and outside of the fin tip of the pleated filter element body, and the second elastic support block can position and support the tail end of the fin. When the fluid is filtered through the fins, the first elastic support block and the second elastic support block can support and dampen the fins, thereby reducing the probability of deformation of the pleated filter element body. The first elastic support block and the second elastic support block can be supported by the folded support net, further ensuring the stability of the pleated filter element when in use, so that the pleated filter element does not need to be provided with a large area of ​​support frame to support the pleated filter element body. It only needs to increase the support of the folded support net to the first elastic support block and the second elastic support block, thereby reducing the probability of deformation of the pleated filter element body and reducing the cost of the pleated filter element.

[0011] Furthermore, a connecting threaded tube is welded through the top of the upper support frame, a socket is opened through the outer peripheral surface of the connecting threaded tube, and the pleated filter element body is clamped and fixed between the upper support frame and the lower support frame;

[0012] The pleated filter element and the filtering device can be connected by connecting the threaded pipe, and the pleated filter element body and the folded supporting net can be positioned by the upper support frame and the lower support frame to ensure the stable use of the pleated filter element during the filtering process.

[0013] Furthermore, a pull ring is clamped and fixed on the top of the pull rope, the pull rope is inserted into the inner side of the socket, and the pull ring is located outside the connecting threaded tube;

[0014] When cleaning the pleated filter element, pulling the pull ring can pull the scraper through the pull rope, driving the scraper to move inside the pleated filter element body, scraping off impurities blocking the surface of the pleated filter element body, making it easy to quickly pour out a large amount of impurities through the connected threaded pipe, and the operation is simple and convenient.

[0015] Furthermore, a winding rope is inserted through the top of the automatic winding component, the top of the winding rope is clamped and fixed to the bottom of the scraper, the automatic winding component is clamped and fixed to the bottom of the lower support frame, and the winding rope is inserted through the bottom of the lower support frame;

[0016] When cleaning the pleated filter element, after moving the scraper to one end of the filter element by pulling the pull rope, the tension on the pull rope is released and the scraper can be reset under the action of the automatic winding component and the winding rope tension, further reducing the difficulty of cleaning and improving the convenience of use.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that the pleated filter element repeatedly folds the filter screen, thereby increasing the contact area between the filter element and the fluid during filtration and improving the filtration efficiency. However, in actual use, the filter screen has many dead corners that are easily blocked by impurities due to the large number of folded positions, and the impurities in the dead corners are difficult to be quickly removed during regular cleaning, and the cleaning operation is relatively time-consuming and labor-intensive. When cleaning the pleated filter element, the pull rope is pulled to drive the scraper to slide in the main body of the pleated filter element to scrape off the impurities blocked in the main body of the pleated filter element, and after the pulling force on the pull rope is released, the scraper is reset under the action of the automatic winding assembly and the pulling force of the winding rope. The cleaning operation is simple and convenient, and the labor intensity of the staff is reduced.

[0019] The utility model solves the problem that when the fluid flows from the inside of the filter element to the outside or from the outside to the inside for filtering during the use of the filter element, a certain pressure is often exerted on the filter element. In order to prevent the filter element from being deformed due to long-term use, a support frame is usually required to be provided on the outside of the filter element for support. However, the structure of the pleated filter element is relatively special. Due to the increased contact area with the fluid, the pressure exerted on the fins of the pleated filter element when the fluid flows increases, which makes it more likely to cause deformation and damage to the fins of a single filter element, thereby shortening the service life of the pleated filter element. The upper and lower support frames are used to support the upper and lower parts of the filter element body. The first elastic support block can support the inner and outer ends of the fin tips of the pleated filter element body, and the second elastic support block can support the tail ends of the fins. When the fluid passes through the fins of the filter element body for filtration, the first elastic support block and the second elastic support block can support and dampen the fins, thereby reducing the probability of deformation of the pleated filter element body. The pleated filter element does not need to be provided with a large support frame to support the pleated filter element body. It only needs to increase the support of the folded support net to the first elastic support block and the second elastic support block, thereby reducing the probability of deformation of the pleated filter element body and reducing the cost of the pleated filter element.
