Technical Field
[0001] This utility model relates to the field of dust collector technology, and in particular to a dust collector frame fixing device. Background Technology
[0002] In baghouse dust collectors, the reliability of the filter cage's fixation directly affects the filter bag's lifespan and dust collection efficiency. Traditional fixing methods have the following drawbacks: low installation efficiency: relying on bolts or welding for fixing, installing a single cage section takes more than 30 minutes and requires multiple people to work together; insufficient vibration resistance: prone to loosening and shifting under high-frequency vibration, leading to a filter bag friction damage rate increase of more than 30%; high maintenance difficulty: requiring destructive disassembly, unable to achieve modular replacement, resulting in long downtime; poor sealing performance: high air leakage rate at the connection between the tube sheet and the cage (generally >3%), causing gas short circuits and affecting dust collection efficiency. Existing improvement solutions, such as snap-fit or plug-in structures, improve installation speed, but still do not solve the problem of self-locking stability under dynamic operating conditions. For example, the four-point snap-fit design is prone to jamming after dust accumulation, and the spring return mechanism is prone to fatigue failure under long-term vibration. In addition, high temperature and high corrosion environments accelerate the corrosion of metal components, further reducing the fixing strength. Therefore, there is an urgent need to develop a new type of fixing equipment that combines rapid installation, vibration-resistant self-locking, and corrosion resistance to adapt to complex operating conditions and reduce the total life cycle cost.
[0003] Traditional dust collector frame fixing methods generally have the following drawbacks: low installation efficiency (requiring multiple people to work together to tighten the bolts, and long installation time for a single frame section); insufficient vibration resistance (prone to loosening and displacement under high-frequency vibration, leading to increased filter bag wear); and high maintenance difficulty (requiring destructive removal with special tools, making modular replacement impossible). Therefore, we propose a dust collector frame fixing device to solve this problem. Utility Model Content
