Description

Technical Field

[0001] This utility model relates to the field of membrane filter bag technology, specifically a membrane filter bag that is easy to peel off dust. Background Technology

[0002] Membrane-coated filter bags are bonded to different needle-punched felt surfaces using pressure and high temperature. When bonding with thermoplastic fiber felt, we first treat the surface of the felt using a special surface treatment technology before bonding it with a PTFE film. Non-thermoplastic fiber felt must first undergo surface chemical and Teflon treatment before bonding with PTFE. A search revealed existing publicly available technology, publication number CN208115352U, which describes a PTFE-coated needle-punched felt filter bag for chemical dust removal, comprising a device body. The device body consists of a bag opening, a bag body, and a bag bottom. The bag bottom is located on one side of the bag body, and the bag opening is located on the bag body away from the bag bottom. A strap is wrapped around the outside of the bag opening, and a strap runs through the inside of the strap. The bag body consists of a polytetrafluoroethylene membrane layer, a hydrophobic layer, and needle-punched felt. The needle-punched felt is composed of a polytetrafluoroethylene (PTFE) film covering the outer side of the needle-punched felt and a hydrophobic layer covering the inner side of the needle-punched felt. The hydrophobic layer is set as a nano-coating. This utility model uses a special thermal lamination process to laminate the needle-punched felt and the film together. The surface is smooth, the dust removal strength is high, it is easy to clean, and the filtration efficiency is high. At the same time, the product has excellent chemical stability and corrosion resistance. The glass fiber needle-punched felt has a strong adaptability to temperature, humidity and corrosive gases. It is even more effective in high humidity and fine particulate dust-laden gases.

[0003] In summary: While the membrane filter bags in the above cases solved the problem of easy dust removal, the membrane filter bags in the above solutions are all single-layer filter bags. In order to increase the filtration effect of the membrane filter bags, the original single-layer filter bags are changed to double-layer filter bags to increase the filtration effect. However, the inner membrane filter bag of the double-layer membrane filter bag will fold during use, thus affecting filtration. In addition, the existing double-layer membrane filter bags are not easy to clean. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a membrane filter bag that is easy to peel off dust. This solves the problem that the membrane filter bags in the above-mentioned solutions proposed in the background technology are all single-layer filter bags. In order to increase the filtration effect of the membrane filter bag, the original single-layer filter bag is changed to double-layer to increase the filtration effect. However, the double-layer membrane filter bag will fold during use, which will affect filtration. In addition, the existing double-layer membrane filter bags are not easy to clean.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a membrane filter bag that is easy to peel off dust, comprising an outer membrane filter bag structure, wherein an inner membrane filter bag structure is provided inside the outer membrane filter bag structure;

[0006] The outer membrane filter bag structure includes an installation ring with a connecting ring embedded inside, and a connecting hole is opened on the surface of the connecting ring. At the same time, the outer membrane filter bag body is fixedly installed at the bottom of the installation ring.

[0007] The inner membrane filter bag structure includes a matching ring, and a matching rod is fixedly installed at the bottom of the matching ring, while a connecting bearing is fixedly installed on the axis of the matching ring.

[0008] By adopting the above technical solution, the inner and outer rings are installed by setting up connecting bearings.

[0009] Preferably, a handwheel rod is installed through the connecting bearing, and a scraper rib is welded and fixedly installed at the bottom of the handwheel rod. An inner membrane filter bag body that wraps around the scraper rib is fixedly installed at the bottom of the matching ring.

[0010] By adopting the above technical solution, the rotation adjustment is achieved through the set handwheel lever.

[0011] Preferably, the connecting holes are arranged in a ring array.

[0012] By adopting the above technical solution, the connection hole is used to achieve locking and limiting of the connection.

[0013] Preferably, the matching ring and the connecting ring are arranged in concentric circles.

[0014] By adopting the above technical solution, a matching ring is set up to achieve a co-core connection.

[0015] Preferably, the scraper ribs are U-shaped.

[0016] By adopting the above technical solution, the rotation adjustment is achieved through the setting of scraper ribs.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the membrane filter bag that is easy to peel off dust,

[0018] (1) This case solves the problem that the membrane filter bags in the above solutions are all single-layer filter bags by setting an inner membrane filter bag structure. In order to increase the filtration effect of the membrane filter bag, the original single-layer filter bag is changed to double-layer, thereby increasing the filtration effect. However, the inner membrane filter bag of the double-layer membrane filter bag will fold during use, thus affecting filtration. Moreover, the existing double-layer membrane filter bag is not easy to clean. After matching the matching ring and matching rod with the connecting ring and connecting hole, the inner membrane filter bag body is installed inside the outer membrane filter bag body, thus forming a double-layer setting of the whole membrane filter bag. At the same time, the set scraper ribs completely open the inner membrane filter bag body and place it inside the outer membrane filter bag body to avoid folding.

[0019] (2) The above problems are solved by the handwheel, connecting bearing and scraper rib set in the inner membrane filter bag structure. When the inner wall of the inner membrane filter bag needs to be cleaned, the operator manually rotates the handwheel to drive the scraper rib to rotate, thereby scraping and cleaning the inner wall of the inner membrane filter bag. This also avoids the situation where the entire filter bag needs to be turned over so that the inner wall of the filter bag is outward before the inner wall of the filter bag can be cleaned.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a membrane filter bag that is easy to peel off dust, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes an outer membrane filter bag structure 1. The outer membrane filter bag structure 1 includes an installation ring 101 with a connecting ring 102 embedded and fixed inside. The connecting ring 102 has a connecting hole 103 on its surface. The connecting holes 103 are arranged in a ring array. When the structure is arranged in a ring array, it not only reflects the equidistant arrangement of the structure, but also the axial symmetry of the structure. Furthermore, when the structure is arranged in a ring array, it reflects the practicality of the structure and the matching snap-fit ​​connection and limiting function. At the same time, the outer membrane filter bag body 104 is fixedly installed at the bottom of the installation ring 101.

[0028] like Figure 4 and Figure 5 As shown, the outer membrane filter bag structure 1 has an inner membrane filter bag structure 2 inside. The inner membrane filter bag structure 2 includes a matching ring 201, and a matching rod 202 is embedded and fixedly installed at the bottom of the matching ring 201. At the same time, a connecting bearing 203 is fixedly installed on the axis of the matching ring 201. The matching ring 201 and the connecting ring 102 are arranged in concentric circles. When the two are arranged in concentric circles, it not only reflects the coaxial matching connection between the two, but also reflects the integrity of the matching connection. Furthermore, the concentric arrangement of the two reflects the tightness of the matching connection and the ability to be quickly separated under force and pull. It also reflects the practicality of the superimposed matching arrangement.

[0029] Furthermore, in the above scheme, a handwheel rod 204 is installed through the connecting bearing 203, and a scraper rib 205 is welded and fixedly installed at the bottom of the handwheel rod 204. An inner membrane filter bag body 206 that wraps around the scraper rib 205 is fixedly installed at the bottom of the matching ring 201. The scraper rib 205 is U-shaped. When the above components are U-shaped, it not only reflects the ability of the above components to expand the inner membrane filter bag body 206, but also reflects the relative rotation adjustment of the inner wall of the inner membrane filter bag body 206. Moreover, when the above components are U-shaped, it reflects the quick installation and disassembly between the above components and the outer membrane filter bag body 104.

[0030] In the above scheme, when the outer membrane filter bag 104 is used, it is installed and fixed to the equipment body through the mounting ring 101. After the dust enters the inner membrane filter bag 206 for filtration, the dust enters the inner membrane filter bag 206. At the same time, when the inner membrane filter bag 206 needs to be disassembled, the handwheel rod 204 is manually pulled to cause the matching ring 201 and matching rod 202 to be separated from the connecting ring 102 and connecting hole 103 by force, thereby quickly disassembling the entire inner membrane filter bag 206 from the outer membrane filter bag 104 for cleaning. Alternatively, when the inner membrane filter bag 206 is fixed inside the outer membrane filter bag 104, the handwheel rod 204 is rotated to rotate the scraper rib 205 to clean the inner wall of the inner membrane filter bag 206.
