Description

Technical Field

[0001] The utility model relates to the technical field of film-coated high-temperature resistant filter bags, and more specifically, to a film-coated high-temperature resistant filter bag. Background Art

[0002] Under the current technological background, although high-temperature resistant coated filter bags are extremely common in industrial applications, they face many technical challenges. These problems mainly involve durability, ease of installation and reinforcement of filter bags.

[0003] First of all, due to its relatively simple structure, the membrane filter bag is easily affected by many factors during long-term use. The impact of high-pressure air, the inclination of the spray pipe and the deformation of the flower plate may cause damage to the filter bag mouth. This damage may cause the filter bag mouth to crack. In severe cases, the bag head and the bag body may even separate, which not only affects the normal service life of the filter bag, but may also affect the filtration efficiency and safety of the entire system due to reduced filtration efficiency.

[0004] Secondly, the membrane filter bags in the prior art have great difficulties in the installation process, especially in application scenarios that require frequent replacement or maintenance. The lack of a detachable quick installation and disassembly mechanism increases the complexity of the operation, which not only consumes more manpower and time, but also increases the error rate during the operation, which has an adverse impact on maintenance efficiency and cost control.

[0005] In addition, although some filter bags on the market have adopted structures such as pressure rings for external reinforcement to enhance the structural stability and durability of the filter bags, these reinforcement structures often fail to achieve quick connection with the filter bags, which means that even after reinforcement, the installation or replacement of the filter bags is still cumbersome and complicated, which limits the performance of the filter bags when rapid response or emergency maintenance is required.
