Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a filter bag installation sealing structure. Background Art

[0002] The filter bag is a filter element used in the dust collector. It mainly captures, intercepts and filters solid particles in the airflow to purify the gas and protect the environment. The filter bag is usually made of textile materials or non-textile materials. These materials have sufficient filtration efficiency, strength and durability to adapt to different working conditions. The existing filter bags are usually loosened and fallen off during the dust removal process due to the impact of dust and the fluctuation of airflow during use, making it difficult for the equipment to achieve the expected dust removal effect, causing dust to be discharged into the environment, affecting the air quality and reducing the overall filtration effect. Therefore, we propose a filter bag installation sealing structure to solve the above problems. Utility Model Content

[0003] In order to overcome the problem of existing filter bags, filter bags are usually easily loosened and fallen off due to the impact of dust and fluctuations of airflow during the dust removal process, making it difficult for the equipment to achieve the expected dust removal effect, causing dust to be discharged into the environment, affecting air quality and reducing the overall filtering effect.

[0004] The technical solution of the utility model is: a filter bag installation sealing structure, including a bag body, a mounting assembly and a positioning assembly; one end of the bag body is equipped with a mounting assembly for ensuring that the filter bag is stably installed in the correct position while ensuring a sealed connection, and the outer end of the bag body is equipped with a positioning assembly for ensuring that the filter bag is accurately positioned.

[0005] Preferably, a connecting pipe is used in combination with a docking plate to fix the device for installation, so as to ensure that the connection between the filter bag and the device is more firm, and the damage or leakage of the filter bag caused by unstable connection is reduced. A plurality of limit plates are used in combination with latches to form auxiliary installation positioning after docking with the device, so as to ensure that the filter bag maintains a precise position during installation and avoids displacement during its use. The latch can be used for auxiliary adjustment according to different sizes and shapes to meet the installation requirements of different equipment. A sealing ring and a sealing strip are installed at the connection with the equipment for sealing, which can fill the gap at the connection between the filter bag and the equipment, reduce gas leakage, and achieve a better sealing effect. The bag body is supported by a fixing ring to fix the connecting frame to maintain the shape and position of the filter bag. At the same time, the ferrule is arranged at the outer end of the bag body, and the telescopic belt is used to stretch and tighten along the inside, and it can be quickly disassembled when it needs to be replaced to meet different fixing requirements. After the telescopic belt is stretched and bound, it is fixed with a limit bolt, so that the filter bag forms a tight seal, reduces gas leakage, and prevents the filter bag from shifting due to vibration or airflow during use, thereby improving the overall stability.

The latches can be assisted to adjust according to different sizes and shapes to meet the installation requirements of different equipment.

[0008] Preferably, a sealing strip is laid on the upper end of the docking plate, and a sealing ring is provided between the sleeve plate and the clamping ring.

[0010] Preferably, the positioning assembly includes a ferrule, a telescopic band and a limit bolt. The ferrule is located at the outer end of the bag body, and the interior of the ferrule is provided with a telescopic band.
