Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a stainless steel sintered felt dust removal felt filter bag. Background Technology

[0002] Stainless steel sintered felt filter bags are felt filter bags made of stainless steel. Felt filter bags are a type of filtration equipment with a cylindrical or bag-like structure used for filtration. They are mostly used for dust removal, while most felt filter bags on the modern market have a cylindrical structure.

[0003] Chinese Patent CN218871545U discloses a stainless steel sintered felt filter bag. Addressing the problem that existing felt filter bags have poor reusability due to their unreusable sealing structure, the following solution is proposed: The bag includes a bag body with an open top. Fixed plates and connecting plates are fixedly installed on the top of both the front and rear sides of the bag. Each connecting plate has a sliding groove on its far side, within which a connecting rod is slidably installed. Each fixed plate has an insertion groove on its far side, within which the connecting rod is slidably installed. A horizontal plate is fixedly installed on the far side of each connecting rod, and a retaining plate is fixedly installed on the near side of each horizontal plate. This technical solution has a reasonable structural design, facilitates opening and sealing of the felt filter bag with high sealing stability, and allows for repeated use, improving its reusability and reliability.

[0004] However, the above technical solutions have the following shortcomings: when the felt filter bag is sealed at the bottom, the dust stored inside the felt filter bag is difficult to clean, and when the felt filter bag is moved to the dust treatment area, it needs to be sealed, and the top opening needs to use a sealing method that minimizes the deformation of the felt filter bag. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a stainless steel sintered felt dust collector filter bag. This bag uses Velcro to allow the bottom opening of the lower sealing belt to be easily opened and closed for cleaning, and the user can use a sealing component to seal and transport the felt filter bag with reduced wrinkles, thereby improving the service life of the felt filter bag.

[0006] The technical solution of this utility model is a stainless steel sintered felt dust collector filter bag, comprising: a felt filter bag, with a drawstring strip and a lower sealing tape respectively provided at its upper and lower ends, the lower sealing tape being provided with Velcro and Velcro, and the drawstring strip being provided with a drawstring tape; a sealing assembly, which is provided in two pairs opposite to each other on the felt filter bag, the sealing assembly including an installation rod provided on the felt filter bag, a connecting block provided on the installation rod, a storage rack rotatably provided on the installation rod, an extension rod slidably provided on the storage rack, multiple rotating rings provided with damping rotation on the extension rod, a connecting rod provided on the extension rod, and a positioning assembly provided on the storage rack.

[0007] Preferably, the positioning component includes a pull rod slidably disposed on the storage rack, and a spring disposed on the storage rack and the pull rod.

[0008] Preferably, the rotating ring is provided with multiple positioning holes evenly distributed on it.

[0009] Preferably, the rotating ring is provided with symmetrically distributed rough blocks and sealing strips at both ends.

[0010] Preferably, the drawstring has a toothed portion, and the drawstring abuts against the limiting component.

[0011] Preferably, the limiting component includes a constriction block, a handle rotatably mounted on the constriction block, an elliptical rod coaxially mounted on the handle, and two limiting blocks slidably mounted relative to each other on the constriction block; the limiting blocks abut against the elliptical rod.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the user covers the dust discharge pipe with the elastic band. Simultaneously, the Velcro tabs and Velcro nut seal the bottom of the felt filter bag until the user replaces it with a new one. This releases the Velcro tabs and nut, creating a lower opening in the filter bag and reducing the difficulty of cleaning its interior. To empty the dust from the filter bag, the user rotates the storage rack, pulls the extension rod and positioning assembly to extend the extension rod to its maximum length, and rotates multiple rotating rings to contact the felt filter bag. This connects the two pairs of mounting rods via corresponding connecting blocks, and the two pairs of storage racks and extension rods seal the felt filter bag, improving its sealing effect during movement.

[0019] Example 1

[0020] like Figures 1-4 As shown, this embodiment proposes a stainless steel sintered felt dust collector filter bag, including a felt filter bag 1 and a sealing assembly 4. The upper and lower ends of the felt filter bag 1 are respectively provided with a drawstring strip 2 and a lower sealing tape 3. The lower sealing tape 3 is provided with Velcro 5 and Velcro 6, and the drawstring strip 2 is provided with a drawstring tape 7. The sealing assembly 4 is provided in two pairs on the felt filter bag 1. The sealing assembly 4 includes an installation rod 41 provided on the felt filter bag 1, a connecting block 42 provided on the installation rod 41, a storage rack 43 rotatably provided on the installation rod 41, an extension rod 46 slidably provided on the storage rack 43, multiple rotating rings 47 provided on the extension rod 46 for damping rotation, a connecting rod 410 provided on the extension rod 46, and a positioning assembly provided on the storage rack 43. The two connecting blocks 42 are two parts of Velcro fasteners.

[0021] In this embodiment, the user covers the dust discharge pipe with the drawstring strip 2. Simultaneously, the Velcro tabs 5 and 6 connect to seal the bottom of the felt filter bag 1 until the user replaces the felt filter bag 1 with a new one. This allows the Velcro tabs 5 and 6 to detach, increasing the bottom opening of the felt filter bag 1 and reducing the difficulty of cleaning its interior. When it's necessary to empty the dust from inside the felt filter bag 1, the storage rack 43 is rotated, and the extension rod 46 and positioning assembly are pulled, extending the extension rod 46 to its maximum length. Multiple rotating rings 47 are then rotated to contact the felt filter bag 1, connecting the two pairs of mounting rods 41 together via corresponding connecting blocks 42. The two pairs of storage racks 43 and the extension rod 46 then seal the felt filter bag 1, improving its sealing effect during movement.

[0022] Example 2

[0023] like Figures 1-3As shown, this embodiment of the stainless steel sintered felt dust collector filter bag, compared to Embodiment 1, includes a positioning component comprising a pull rod 44 slidably mounted on a storage rack 43, and a spring 45 mounted on the storage rack 43 and the pull rod 44. A plurality of positioning holes 471 are evenly arranged on the rotating ring 47. Symmetrically distributed rough blocks 48 and sealing strips 49 are respectively provided at both ends of the rotating ring 47.

[0024] In this embodiment, when the user pulls the pull rod 44, the pull rod 44 is disengaged from the positioning hole 471. After the two storage racks 43 are in contact through the connecting rod 410, the user releases the pull rod 44 and inserts it into the positioning hole 471 to limit the position of the extension rod 46. By overlapping the two connecting rods 410, the sealing assembly 4 can seal the felt filter bag 1 and avoid reducing the sealing length through pleats. This reduces the service life of the felt filter bag caused by pleats and increases the service life of the felt filter bag 1.

[0025] Example 3

[0026] like Figure 1 and Figure 4 As shown, this embodiment of the stainless steel sintered felt dust collector filter bag, compared to Embodiment 1, has a toothed rack portion in the drawstring belt 7, which abuts against a limiting component. The limiting component includes a drawstring block 8, a handle 9 rotatably mounted on the drawstring block 8, an elliptical rod 10 coaxially mounted on the handle 9, and two limiting blocks 11 slidably mounted relative to each other on the drawstring block 8; the limiting blocks 11 abut against the elliptical rod 10.

[0027] In this embodiment, when in use, the user pulls the drawstring 7 to tighten the drawstring strip 2 and allows the drawstring 7 to extend into the drawstring block 8. The limiting block 11 abuts against the rack portion of the drawstring 7, preventing the drawstring 7 from being pulled out of the limiting block 11. The user can rotate the lever 9 as needed, and the lever 9 drives the elliptical rod 10 to rotate, causing the spring-loaded component on the limiting block 11 to move toward the elliptical rod 10. The spring-loaded component can be a common spring such as spring a, which allows the rack portion to disengage from the drawstring 7 and can be removed from the drawstring block 8, improving the effect of the drawstring strip 2 on the pipe.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
