Description

Technical Field

[0001] This utility model belongs to the field of industrial dust removal technology, specifically a high-temperature resistant and wear-resistant multi-layer dust removal filter bag. Background Technology

[0002] Multi-layer filter bags can optimize airflow and dust filtration through different layers. Each layer of material can have different functions, such as enhancing filtration effect and improving the uniformity of airflow distribution. The multi-layer design can effectively capture dust particles of different sizes and improve filtration effect. Because multi-layer dust collector filter bags can better cope with different working environments and maintain high-efficiency filtration for a longer period of time, they can reduce system downtime caused by frequent filter bag replacement and cleaning, thereby reducing energy consumption and production costs.

[0003] The working principle of high-temperature and wear-resistant multilayer dust collector filter bags mainly involves two aspects: multilayer structure and filtration principle. Through the precise application of multilayer structure and filtration principle, high-temperature and wear-resistant multilayer dust collector filter bags can efficiently filter dust-laden gases, providing strong support for air purification.

[0004] Existing dust collector filter bags are mostly connected to the output end of dust collection equipment by binding. When the gas flow rate delivered at the output end of the dust collection equipment is too high and impacts the dust collector filter bag, it will cause the dust collector filter bag to fall off during use. Therefore, a high temperature resistant and wear-resistant multi-layer dust collector filter bag is proposed to address the above problem. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most existing dust collector filter bags are connected to the output end of dust collection equipment by binding. When the gas flow rate delivered at the output end of the dust collection equipment is too high and impacts the dust collector filter bag, it will cause the dust collector filter bag to fall off during use. This utility model proposes a high temperature resistant and wear-resistant multi-layer dust collector filter bag.

[0006] The technical solution adopted by this utility model to solve its technical problem is a high-temperature resistant and wear-resistant multi-layer dust collector filter bag, including a support frame. A dust collector filter bag body is provided on the outside of the support frame. Support plates are fixedly installed on both sides of the support frame. One end of the inner wall of the dust collector filter bag body is fixedly installed on the outside of one of the support plates. A connecting pipe is fixedly installed on one side of one of the support plates. The support plates and the connecting pipe are interconnected. An airflow pipe is slidably installed on the outside of the end of the connecting pipe away from the support plate. A first limiting plate and a second limiting plate are fixedly installed on the outside of the airflow pipe. A lifting plate is provided between the first and second limiting plates. The lifting plate is slidably installed on the outside of the airflow pipe. Multiple mounting grooves are opened inside one end of the airflow pipe. Each part is equipped with a limiting ball, and multiple limiting grooves are opened on one side of the connecting pipe. The exterior of the multiple limiting balls is located inside the mounting groove and the limiting groove. One side of the multiple limiting balls is in close contact with the exterior of the lifting plate, and the other side of the limiting balls is in close contact with the exterior of the connecting pipe. First, one end of the connecting pipe is placed inside the airflow pipe. At this time, the upper and lower ends of the limiting balls located inside the mounting groove are limited by the lifting plate and the connecting pipe, respectively. By limiting the upper and lower ends of the limiting balls, the connection between the airflow pipe and the connecting pipe is fixed, and the dust collector filter bag body is finally installed. By installing the dust collector filter bag body, when the dust collector filter bag body is impacted by the high-speed gas blown out by the dust collector, it can be more firmly connected to the dust collector, preventing the dust collector filter bag body from falling off during dust collection.

[0007] Preferably, a fixing plate is fixedly installed on one end of the inner wall of the airflow pipeline, and a sealing ring is fixedly installed on the outer side of the fixing plate. One end of the connecting pipe is tightly attached to the side of the sealing ring. The sealing ring is made of rubber. By having the connecting pipe tightly attached to the side of the sealing ring, the airtightness of the inside of the conveying pipeline is improved, preventing gas leakage inside the conveying pipeline.

[0008] Preferably, a spring is provided between the first limiting plate and the lifting plate. One end of the spring is fixedly installed on the side of the first limiting plate, and the other end of the spring is fixedly installed on the side of the lifting plate. The spring between the first limiting plate and the lifting plate resets and supports the lifting plate after it is pressed, making it easy to use next time. The force continuously applied by the spring can support the bottom of the lifting plate and prevent it from moving during the limiting of the ball.

[0009] Preferably, a high-temperature resistant layer is fixedly installed on the outside of the dust collector filter bag body. The high-temperature resistant layer can effectively protect the dust collector filter bag body and prevent it from being damaged or deformed due to excessive temperature, thereby extending the service life of the dust collector filter bag body.

[0010] Preferably, a wear-resistant layer is fixedly installed on the outer side of the high-temperature resistant layer. The wear-resistant layer can reduce the friction and wear caused by hard particles carried in the airflow on the surface of the dust collector filter bag body, thereby extending the service life of the dust collector filter bag body.

[0011] Preferably, the diameter of the opening at one end of the multiple mounting grooves gradually decreases until the diameter of the opening is smaller than the diameter of the limiting ball. By making the diameter of the opening inside the mounting groove smaller than the maximum diameter of the limiting ball, the limiting ball is limited, thus preventing it from falling off.

[0012] The advantages of this utility model are:

[0013] This invention addresses the issue of dust filter bags being used to clean dust from the conveyed gas during dust removal. First, one end of the connecting pipe is inserted into the airflow pipe. At this point, the upper and lower ends of a limiting ball located inside the mounting groove are limited by a lifting plate and the connecting pipe, respectively. This limitation of the limiting ball secures the connection between the airflow pipe and the connecting pipe, ultimately achieving the installation of the dust filter bag body. This solves the problem that existing dust filter bags are mostly connected to the output end of dust removal equipment using a binding method. When the gas flow rate at the output end of the dust removal equipment is too high, impacting the dust filter bag, it can cause the dust filter bag to fall off during use. By installing the dust filter bag body, when the dust filter bag body is impacted by the high-speed gas blown out by the dust removal equipment, it achieves a more stable connection with the dust removal equipment, preventing the dust filter bag body from falling off during dust removal.

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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a high-temperature and wear-resistant multi-layer dust collector filter bag includes a support 1. A dust collector filter bag body 3 is mounted on the outside of the support 1. Support plates 2 are fixedly installed on both sides of the support 1. One end of the inner wall of the dust collector filter bag body 3 is fixedly installed on the outside of one of the support plates 2. A connecting pipe 4 is fixedly installed on one side of one of the support plates 2. The support plates 2 and the connecting pipe 4 are interconnected. An airflow pipe 5 is slidably installed on the outside of the end of the connecting pipe 4 away from the support plate 2. A first... A lifting plate 8 is provided between the first limiting plate 6 and the second limiting plate 7. The lifting plate 8 is slidably installed on the outside of the airflow pipe 5. Multiple mounting grooves 9 are opened inside one end of the airflow pipe 5. Each mounting groove 9 is provided with a limiting ball 10. Multiple limiting grooves 11 are opened on the side of one end of the connecting pipe 4. The outside of the multiple limiting balls 10 is located inside the mounting grooves 9 and the limiting grooves 11. One side of the multiple limiting balls 10 is in close contact with the outside of the lifting plate 8, and the other side of the limiting balls 10 is in close contact with the outside of the lifting plate 8. It is tightly attached to the outside of the connecting pipe 4. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which leads to the problem of the dust collector filter bags falling off when subjected to large impact forces. In order to make the dust collector filter bags more stable during installation, when using the dust collector filter bags to clean the dust inside the conveyed gas during the dust collection process, the support plate 2 and bracket 1, which are fixedly installed inside the dust collector filter bag body 3, are first placed outside the output end of the dust collection equipment. Then, the connecting pipe 4 outside the support plate 2 is placed inside the airflow pipe 5. When one side of the connecting pipe 4 is in close contact with the side of the sealing ring 14, the limiting ball 10 located inside the mounting groove 9 will fall down into the limiting groove 11 opened inside the connecting pipe 4. When the bottom of the limiting ball 10 is supported, the top of the limiting ball 10 will be limited by the bottom of the lifting plate 8. By limiting the upper and lower ends of the limiting ball 10, the connection between the airflow pipe 5 and the connecting pipe 4 is fixed.

[0023] A fixing plate 13 is fixedly installed on one end of the inner wall of the airflow duct 5, and a sealing ring 14 is fixedly installed on the outer side of the fixing plate 13. One end of the connecting pipe 4 is tightly attached to the side of the sealing ring 14, which is made of rubber. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which causes the dust collector filter bags to fall off when subjected to a large impact. In order to make the dust collector filter bags more stable during installation, this device improves the airtightness of the conveying pipeline by tightly attaching the connecting pipe 4 to the side of the sealing ring 14, thus preventing gas leakage inside the conveying pipeline.

[0024] A spring 12 is provided between the first limiting plate 6 and the lifting plate 8. One end of the spring 12 is fixedly installed on the side of the first limiting plate 6, and the other end of the spring 12 is fixedly installed on the side of the lifting plate 8. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which causes the dust collector filter bags to fall off when subjected to a large impact. In order to make the dust collector filter bags more stable during installation, the spring 12 provided between the first limiting plate 6 and the lifting plate 8 resets and supports the lifting plate 8 after it is pressed, so that it is easy to use next time after use.

[0025] The dust collector filter bag body 3 is externally fixed with a high-temperature resistant layer 15. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which leads to the problem of the dust collector filter bag falling off when subjected to a large impact. In order to make the dust collector filter bag more stable during installation, the high-temperature resistant layer 15 can effectively protect the dust collector filter bag body 3, prevent it from being damaged or deformed due to excessive temperature, and thus extend the service life of the dust collector filter bag body 3.

[0026] A wear-resistant layer 16 is fixedly installed on one side of the high-temperature resistant layer 15. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which leads to the problem of the dust collector filter bags falling off when subjected to large impact forces. In order to make the dust collector filter bag more stable during installation, the wear-resistant layer 16 can reduce the friction and wear effect of hard particles carried in the airflow on the surface of the dust collector filter bag body 3, thereby extending the service life of the dust collector filter bag body 3.

[0027] The diameter of the opening at one end of the multiple mounting slots 9 gradually decreases until the diameter of the opening is smaller than the diameter of the limiting ball 10. During operation, existing dust collector filter bags are mostly fixed by binding when connected to dust collection equipment, which causes the dust collector filter bags to fall off when subjected to a large impact. In order to make the dust collector filter bags more stable during installation, this device limits the limiting ball 10 by making the diameter of the opening inside the mounting slot 9 smaller than the maximum diameter of the limiting ball 10, thus preventing it from falling off.

[0028] Working principle: When cleaning dust inside the conveyed gas using a dust collector filter bag during the dust removal process, firstly, the support plate 2 and bracket 1, which are fixedly installed inside the dust collector filter bag body 3, are placed outside the output end of the dust collector. Then, the connecting pipe 4 outside the support plate 2 is placed inside the airflow pipe 5. When one end of the connecting pipe 4 is tightly pressed against the side of the sealing ring 14, the limiting ball 10 located inside the mounting groove 9 will fall downward into the limiting groove 11 opened inside the connecting pipe 4. When the bottom of the limiting ball 10 is... When the support is reached, the top of the limiting ball 10 will be limited by the bottom of the lifting plate 8. By limiting the upper and lower ends of the limiting ball 10, the connection between the airflow pipe 5 and the connecting pipe 4 is fixed. When the dust removal is completed and the dust filter bag body 3 needs to be disassembled, the bottom of the lifting plate 8 is moved backward to disengage from the limiting ball 10. At this time, the connecting pipe 4 is pulled backward, and the limiting ball 10 inside the limiting groove 11 will move upward, thus achieving the effect of disassembling the dust filter bag body 3.
