Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically a multi-layer pressure-resistant filter bag. Background Technology

[0002] Filter bags are a common type of filtration equipment. They work by using the filter media inside the bag to filter and separate particulate matter in the air, thereby purifying the air. Filter bags are usually made of bag-shaped filter media, such as polyester fiber and glass fiber. These filter media have high capture efficiency and a large filtration area, and can effectively capture particulate matter in the air, such as dust, smoke, and bacteria.

[0003] An investigation revealed that a Chinese utility model patent discloses a multi-layer dust collector filter bag (publication number: CN208082045U), comprising a bag body, a sealing line, a dust-collecting layer, a graphene fiber layer, and a polytetrafluoroethylene (PTFE) support layer. The bag body is cylindrical. The sealing line is located inside the bag body and is connected to the bag body by stitching. The dust-collecting layer is located on the innermost side of the bag body and is an integral structure with the bag body. The graphene fiber layer is located outside the dust-collecting layer and is connected to the dust-collecting layer by needle punching. The PTFE support layer is located outside the graphene fiber layer and is connected to the graphene fiber layer by needle punching.

[0004] In the aforementioned patent, the overall wear resistance, corrosion resistance, and high-temperature resistance of the filter bag are improved by setting the dust-facing surface, the polytetrafluoroethylene support layer, and the graphene fiber layer. However, in actual use, since the filter bag is relatively soft, when the pressure inside the dust removal equipment is too high, the wind speed will increase. At this time, the filter bag may shake violently, which may accelerate the wear of the filter bag and thus shorten its service life.

[0005] Therefore, this utility model provides a multi-layer pressure-resistant cloth bag to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a multi-layer pressure-resistant cloth bag, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the pressure-resistant cloth bag includes an installation ring 1, an outer bag 2 located at the bottom of the installation ring 1, an inner bag 3 located inside the outer bag 2, a pressure-resistant ring 6 fitted on the side surface of the inner bag 3, a first connecting strap 12 fitted on the side surface of the pressure-resistant ring 6, a connector 13 fixedly installed on the end of the first connecting strap 12 away from the pressure-resistant ring 6, an insert 15 rotatably installed on the connector 13, a second connecting strap 18 fixedly installed on the inner wall of the outer bag 2, an insert post 19 fixedly installed on the end of the second connecting strap 18 away from the outer bag 2, a connecting sleeve 8 fitted on the side surface of the pressure-resistant ring 6, and a connecting rod 7 fixedly installed on the connecting sleeve 8. The insert 15 has a slot 22 for the insert post 19 to be inserted into.

[0027] Multiple pressure-resistant rings 6 are arranged in a linear array vertically on the side surface of the inner bag 3. Each pair of adjacent pressure-resistant rings 6 is connected to a connecting rod 7 via a connecting sleeve 8, thus forming a complete pressure-resistant frame. The pressure-resistant frame provides good support for the pressure-resistant bag. When using the bag, the pressure-resistant frame formed by the pressure-resistant rings 6 needs to be placed on the side surface of the inner bag 3, and then the outer bag 2 is placed on the side surfaces of the inner bag 3 and the pressure-resistant frame. After the outer bag 2 is placed on the side surfaces of the inner bag 3 and the pressure-resistant frame, the insert post 19 inside the outer bag 2 can be inserted into the insert tube 15 on the pressure-resistant ring 6 to form a stable connection, reducing the possibility of violent shaking of the bag and helping to improve the service life of the bag.

[0028] Furthermore, in order to improve the stability of the inner bag 3 during the use of the pressure-resistant fabric bag, such as... Figure 1 , Figure 2 and Figure 3 As shown, a fixing strap 9 is fixedly connected to the side surface of the inner bag 3, a hook and loop fastener 10 is fixedly connected to one side of the fixing strap 9, a hook and loop fastener 11 is fixedly connected to the side surface of the inner bag 3, and one side of the fixing strap 9 is attached to the side surface of the pressure-resistant ring 6.

[0029] Before the outer bag 2 is fitted onto the inner bag 3 and the side surface of the pressure-resistant frame, the pressure-resistant frame formed by the pressure-resistant rings 6 needs to be fitted onto the side surface of the inner bag 3. After the fitting is completed, the fixing strap 9 on the side surface of the inner bag 3 can be pulled to wrap around the outside of the pressure-resistant frame. Then, the hook and loop fastener 10 on the fixing strap 9 is attached to the hook and loop fastener 11. At this time, a relatively stable connection is formed between the inner bag 3 and the pressure-resistant frame formed by the pressure-resistant rings 6, which reduces the occurrence of folding and displacement of the inner bag 3 and improves the stability of the inner bag 3 when the pressure-resistant cloth bag is used.

[0030] Furthermore, to improve the strength of the connection between the compression ring 6 and the outer bag 2, such as... Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a guide groove 21 is provided on the insert 15, which is connected to the slot 22. A locking block 20 is fixedly connected to the side surface of the insert post 19, and the side surface of the locking block 20 slides against the inner wall of the guide groove 21.

[0031] The slot 22 has a sliding connection to a pressure plate 16. A spring 17 is fixedly connected to one side of the pressure plate 16. The end of the spring 17 away from the pressure plate 16 is fixedly connected to the bottom inner wall of the slot 22. The side of the pressure plate 16 away from the spring 17 is in contact with the end of the insert 19 away from the second connecting band 18.

[0032] After the outer bag 2 is placed on the side surface of the inner bag 3 and the pressure-resistant frame, the insert post 19 inside the outer bag 2 needs to be inserted into the insert cylinder 15 on the pressure-resistant ring 6. The guide groove 21 on the insert cylinder 15 is hook-shaped. When the insert post 19 is inserted into the slot 22, the locking block 20 will also come into the guide groove 21. Guided by the guide groove 21, the insert post 19 and the locking block 20 are inserted into the insert cylinder 15 in a rotating forward manner. During this process, the insert post 19 will come into contact with the pressure plate 16 and squeeze the pressure plate 16, so that... The pressure plate 16 moves inside the slot 22, which also compresses the spring 17. When the locking block 20 reaches the bend of the guide groove 21, the insert post 19 and the locking block 20 need to continue to rotate and move back a short distance along the trajectory of the guide groove 21. Then the inner wall of the guide groove 21 can abut against the locking block 20. The spring 17 will also apply force to the insert post 19 through the pressure plate 16, so that the insert post 19 can be stably maintained in its current state, which helps to improve the firmness of the connection between the pressure ring 6 and the outer bag 2.

[0033] It should be noted that, in order to improve the service life of the second connecting belt 18, such as... Figure 3 , Figure 4 and Figure 6 As shown, a rotating block 14 is fixedly connected to one end of the insert 15. A rotating groove is provided on the connector 13, and the side surface of the rotating block 14 is in contact with the inner wall of the rotating groove.

[0034] The rotating block 14 is inverted T-shaped, and the rotating groove is convex. The insert 15 can rotate on the connector 13 through the rotating block 14. After the outer bag 2 is placed on the side surface of the inner bag 3 and the pressure-resistant frame, the insert post 19 inside the outer bag 2 needs to be inserted into the insert 15 on the pressure-resistant ring 6. Guided by the guide groove 21, the insert post 19 and the locking block 20 are inserted into the insert 15 in a rotating forward manner. During this process, the second connecting strip 18 connected to the insert post 19 will also be twisted. After the insert post 19 and the insert 15 are connected, the insert 15 can be rotated directly, so that the insert 15, along with the insert post 19 and the second connecting strip 18, rotates in the opposite direction of insertion, thereby restoring the second connecting strip 18 to its initial state, which helps to improve the service life of the second connecting strip 18.

[0035] Furthermore, to facilitate the use of these pressure-resistant bags by staff, such as... Figure 1 , Figure 2 and Figure 3 As shown, the top of the outer bag 2 is fixedly connected to the first connecting end 4, and the top of the inner bag 3 is fixedly connected to the second connecting end 5. Both the first connecting end 4 and the second connecting end 5 are snapped into the bottom of the mounting ring 1.

[0036] The pressure-resistant filter bag is installed on the dust collector via the mounting ring 1. Before installing the filter bag, the inner bag 3, outer bag 2, and pressure-resistant frame (assembled from the pressure-resistant ring 6) need to be installed onto the mounting ring 1 one by one. First, the inner bag 3 can be directly snapped onto the mounting ring 1 via the second connecting end 5 at the top. Then, the pressure-resistant frame (assembled from the pressure-resistant ring 6) is fitted onto the side surface of the inner bag 3, and the pressure-resistant frame needs to be fixed to the inner bag 3 using the fixing strap 9. The outer bag 2 is placed on the side surface of the pressure-resistant frame and the inner bag 3. At the same time, the insert post 19 is inserted into the insert cylinder 15 to establish a stable connection between the pressure-resistant frame and the outer bag 2. Finally, the outer bag 2 is snapped onto the mounting ring 1 through the first connecting end 4 at the top of the outer bag 2, thus completing the assembly of the pressure-resistant cloth bag. When cleaning the pressure-resistant cloth bag, simply reverse the above steps to disassemble the pressure-resistant frame composed of the inner bag 3, the outer bag 2, and the pressure-resistant ring 6 one by one. It is relatively simple to operate in actual application.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
