Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag assembly for a baghouse dust collector. Background Technology

[0002] With the rapid increase in industrial activities, smoke and dust pollution has become increasingly serious. Particulate matter with diameters of less than 2.5 micrometers and larger than 2.5 micrometers caused by industrial smoke and dust, construction dust, etc., has become the main pollutant in my country at present. Haze is affecting people's lives, and dust control has become urgent. Among them, bag filters are widely used and are one of the most effective types of dust collectors available. They can achieve a collection efficiency of more than 99% for particulate matter. Filter bags can be made from various woven or felt materials or mixtures thereof.

[0003] Existing patent document CN215692478U discloses a dust collector filter bag assembly, including a base plate and a mounting ring fixedly disposed on the side of the base plate. The base plate has a threaded groove inside, and a threaded rod is threaded into the groove. The base plate is disposed on the inner wall of the dust collector. A filter bag is connected inside the mounting ring, and connecting rings are connected to the upper and lower ends of the filter bag. The connection between the mounting ring and the filter bag is an opening. The mounting ring has, from the outside to the inside, an outer ring, a connecting groove, and an inner ring. A clamping mechanism is disposed inside the outer ring, penetrating the connecting groove and the inner ring. A connecting ring is disposed inside the inner ring. This dust collector filter bag assembly provides a clamping mechanism, making filter bag installation simple and convenient, and facilitating subsequent disassembly and replacement.

[0004] However, existing bag filter bag assemblies consist of filter bags and frames. During use, the filter bags need to be installed on the frames. However, during installation, the filter bags and frames are mostly fixed with bolts, which makes the filter bag installation operation cumbersome and inconvenient to disassemble. To address this, we propose a new bag filter bag assembly for bag filters. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a dust collector filter bag assembly for a baghouse dust collector, which has the following beneficial effects:

[0016] (1) This type of bag filter assembly, through the provided push-pull rod, pull ring, telescopic spring, and fixing plate, allows the filter bag to be installed with the frame. The operator places the filter bag body in the gap between the outer and inner frames, inserts their finger into the pull ring, and pulls it inward. The pull ring, through the push-pull rod, causes the fixing plate to retract into the receiving groove. Simultaneously, the telescopic spring retracts, allowing the filter bag body to be positioned outside the frame tube. The operator then releases the pull ring, and the telescopic spring utilizes its elasticity... This will push the fixing plate outward, thus opening the filter bag body outward. The filter bag body will then be firmly fixed to the skeleton tube. During disassembly, the worker only needs to pull the pull ring inward. The pull ring, through the push-pull rod, causes the fixing plate to retract into the storage groove. At this time, the fixing plate will release the filter bag body, and then the filter bag body can be pulled down to remove it. Therefore, the push-pull rod, pull ring, telescopic spring, and fixing plate make installation and disassembly easier, facilitating the installation and removal of the filter bag and the skeleton together.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a dust collector filter bag assembly for a bag filter, including a skeleton tube 2, a collar 3 fixedly connected to the top end of the skeleton tube 2, an inner skeleton 8 fixedly connected to the bottom of the skeleton tube 2, and a filter bag body 1 movably connected to the outer side of the inner skeleton 8. The filter bag body 1 includes a first electrostatic layer 101, a substrate layer 102, a high-temperature resistant layer 103, a second electrostatic layer 104, and a waterproof layer 105. The substrate layer 102 is fixedly connected to the bottom of the first electrostatic layer 101, the high-temperature resistant layer 103 is fixedly connected to the bottom of the substrate layer 102, the second electrostatic layer 104 is fixedly connected to the bottom of the high-temperature resistant layer 103, and the waterproof layer 105 is fixedly connected to the bottom of the second electrostatic layer 104. A storage groove 9 is provided on the outer side of the skeleton tube 2, and a push-pull rod 4 is movably connected to the inner side of the skeleton tube 2. A pull ring 5 is fixedly connected to one end of the push-pull rod 4, a telescopic spring 501 is movably connected to the outer side of the push-pull rod 4, and a fixing plate 10 is fixedly connected to the other end of the push-pull rod 4.

[0024] In this embodiment, specifically, the bottom of the collar 3 is fixedly connected to the outer frame 6, and the bottom end of the outer frame 6 is fixedly connected to the outer ring 7. The outer frame 6 and the outer ring 7 can play the role of shaping the filter bag body 1 and prevent the filter bag body 1 from bursting.

[0025] In this embodiment, specifically, three outer frames 6 are provided. The three outer frames 6 have the same length and are all cylindrical. The outer frames 6 can play a role in shaping the filter bag body 1 and prevent the filter bag body 1 from bursting.

[0026] In this embodiment, specifically, the first electrostatic layer 101 is fixedly connected to the inner surface of the filter bag body 1, and the waterproof layer 105 is fixedly connected to the outer surface of the filter bag body 1. The first electrostatic layer 101 can prevent the generation of static electricity, and the waterproof layer 105 can play a waterproof role.

[0027] In this embodiment, specifically, the substrate layer 102 is made of polyester material, and the thickness of the substrate layer 102 is 1 to 2 millimeters. The substrate layer 102 made of polyester material is more durable.

[0028] In this embodiment, specifically, three fixing plates 10 are provided. All three fixing plates 10 have an arc-shaped structure, and the three fixing plates 10 are combined to form a disc shape. The fixing plates 10 can better fix the filter bag body 1.

[0029] Working Principle: After installation, first check the installation, fixation, and safety features of this utility model. When it is necessary to install the filter bag and the frame together, the worker places the filter bag body 1 in the gap between the outer frame 6 and the inner frame 8, then inserts a finger into the pull ring 5 and pulls it inward. The pull ring 5, through the push-pull rod 4, causes the fixing plate 10 to retract into the storage groove 9. At the same time, the telescopic spring 501 retracts, and the filter bag body 1 can then be placed outside the frame tube 2. Then, the worker releases the pull ring 5, and the telescopic spring 501 retracts. The inherent elasticity of the filter bag will push the fixing plate 10 outward, thus opening the filter bag body 1. The filter bag body 1 will then be firmly fixed to the skeleton tube 2. During disassembly, the operator only needs to pull the pull ring 5 inward. The pull ring 5, through the push-pull rod 4, causes the fixing plate 10 to retract into the storage groove 9. At this time, the fixing plate 10 will loosen the filter bag body 1, and then the filter bag body 1 can be pulled down to disassemble it. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
