Abstract

This application provides a flame-retardant nonwoven filter element, including a filter element mechanism for filtering substances contained in a target object and a fixing mechanism for securing the filter element. An installation mechanism for providing support to the filter element is provided on the outside of the filter element mechanism. The installation mechanism includes a slot and a block. The slot is located below the filter element mechanism, and the block is slidably connected to the slot. The top of the filter element mechanism is fitted to the bottom of the fixing mechanism. This invention, by setting up an installation mechanism, allows the block connected to the sealing ring on the outside of the plug plate to be inserted into an insertion slot in the outer cylinder. Rotating the rotating plate causes the plug plate to rotate, which in turn causes the block to rotate within the moving groove until it falls into the slot, thus installing the plug plate. This improves the stability and ease of installation of the installation mechanism components, extends the service life of the support components, and ensures the normal operation of the filter element's filtration function.

Description

Technical Field

[0001] This application relates to the field of filter element technology, specifically to a flame-retardant nonwoven filter element. Background Technology

[0002] The filter element is the heart of the filter, as its name suggests. The main function of the filter element, and indeed the core principle of the filter, is to purify raw materials and facilitate their reuse. Filter elements remove impurities from the filter medium, protecting the equipment and ensuring air cleanliness. When fluid passes through a filter element with a certain precision, impurities are blocked, while clean fluid flows out.

[0003] In the prior art, CN219091267U discloses an antistatic non-woven filter element, which discloses that the two ends of the filter element can be embedded and fixed by the base and end cap, and the entire filter element can be supported upright by the support of the cylinder to ensure stable filtration.

[0004] However, the external support assembly of the aforementioned antistatic nonwoven filter cartridge relies on the spring force itself to ensure the stability of the support assembly. After prolonged use, the spring performance may deteriorate and fail to provide adequate support, thereby shortening the service life of the support assembly and compromising the normal function of the filter cartridge. Utility Model Content

The filter element mechanism is provided with an installation mechanism on its outer side for providing support for the filter element. The installation mechanism includes a slot and a block. The slot is located below the filter element mechanism, and the block is slidably connected to the slot. The top of the filter element mechanism is attached to the bottom of the fixing mechanism.

[0007] By adopting the above technical solution, the blocking plate can be installed inside the outer cylinder by using the card block to insert into the card slot, which improves the convenience and stability of the installation mechanism.

[0008] Preferably, the installation mechanism includes an outer cylinder and a movable groove. Insertion grooves are provided on both the left and right sides of the bottom of the outer cylinder. The movable groove is provided on one side of the insertion groove, and the locking groove is provided on the other side of the movable groove.

[0009] By adopting the above technical solution, the outer cylinder can provide support and protection for the filter element while facilitating its placement. Furthermore, the connection between the insertion slot, the moving slot, and the card slot ensures that the plug with the card block can be installed quickly.

[0010] Preferably, the installation mechanism further includes a blocking plate and a sealing ring. The blocking plate is disposed inside the lower part of the outer cylinder. A rotating plate is connected to the bottom of the blocking plate. The inner wall of the sealing ring is connected to the side of the blocking plate. Both the left and right sides of the sealing ring are connected to one side of the locking block.

[0011] By adopting the above technical solution, the movement of the blocking plate can be controlled by the rotating plate, and the sealing ring on the side of the blocking plate can be used to improve the sealing of the bottom of the outer cylinder, thus preventing some substances from entering the filter element directly without being filtered.

[0012] Preferably, the filter element mechanism includes an antistatic layer and a filter layer, the antistatic layer is disposed inside the outer cylinder, and the inner wall of the filter layer is connected to the outer side of the antistatic layer.

[0013] By adopting the above technical solution, the antistatic layer can be used to prevent static electricity from being generated during filtration, thereby improving the safety of the filter element, and the non-woven fabric filter layer can be used to filter the target substance.

[0014] Preferably, the filter element mechanism further includes a placement groove and a sprayed coating layer for improving the flame retardant performance of the filter element. The placement groove is located on the top of the blocking plate. The inner wall of the sprayed coating layer is connected to the outer side of the filter layer. The bottom of the sprayed coating layer, the filter layer, and the antistatic layer are all in contact with the bottom of the inner wall of the placement groove.

[0015] By adopting the above technical solution, the placement groove can be used to easily fix the position of the filter element, and the spray coating can be used to reduce the possibility of filter element combustion and extend the service life of the filter element.

[0016] Preferably, the fixing mechanism includes a retaining groove and a top plate, the retaining groove being formed at the top of the outer cylinder, and the bottom of the top plate being fitted to the top of the outer cylinder.

[0017] By adopting the above technical solution, the retaining groove can be used to provide connection space for the rubber strip, and the top plate can be used to retain the filter element from above.

[0018] Preferably, the fixing mechanism further includes a rubber strip and a retaining block, the bottom of the rubber strip is connected to the bottom of the inner wall of the retaining groove, the top of the retaining block is connected to one side of the bottom of the top plate, and the side of the retaining block is slidably connected to the inner wall of the retaining groove.

[0019] By adopting the above technical solution, the position of the retaining block can be restricted by the rubber strip surface when the top plate rotates, thereby enhancing the stability of the top plate position.

[0020] Preferably, the fixing mechanism further includes an external threaded tube and a fixing groove. The top of the external threaded tube is connected to the center of the bottom of the top plate, and the side of the external threaded tube is threaded to the upper part of the inner wall of the outer cylinder. The fixing groove is opened at the bottom of the external threaded tube, and the inner wall of the fixing groove is in contact with the top of the sprayed coating layer, the filter layer and the antistatic layer.

[0021] By adopting the above technical solution, the threaded connection between the external threaded pipe and the inner wall of the outer cylinder can be used to facilitate the installation of the top plate, and the filter element that fits against the inner wall of the fixed groove at the top can be used to restrict the position of the block with the placement groove.

[0022] The beneficial effects of this application are as follows:

[0023] 1. By setting up an installation mechanism, the locking block connected to the sealing ring on the outside of the plug plate is inserted into the insertion slot opened in the outer cylinder. Rotating the rotating plate drives the plug plate to rotate, and the rotation of the plug plate drives the locking block to rotate in the moving slot until it falls into the slot, thus installing the plug plate. This improves the stability and ease of installation of the installation mechanism components, extends the service life of the support components, and ensures the normal use of the filter element's filtration function.

[0024] 2. By setting up a filter element mechanism, the filter element is placed in the placement slot. The anti-static layer reduces the probability of static electricity generation, the filter layer filters external substances, and the spray coating reduces the possibility of filter element combustion, thereby improving the safety of filter element use and extending the service life of filter element.
