Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical equipment, specifically relating to an anti-clogging feeding device with an air hammer. Background Technology
[0002] Chemical enterprises, whose raw materials and products are mostly flammable, explosive, and toxic, inherently carry high risks. Operating conditions involve high temperatures and pressures, leading to frequent accidents in all aspects of the production, use, storage, and handling of hazardous chemicals. To minimize the number of on-site operators, chemical enterprises are currently implementing measures of "automation to reduce manpower and mechanization to replace manpower." This means that the entire process, from raw material input to final product output, requires automated control.
[0003] Currently, most reaction units in chemical enterprises are basically automated. For the feeding of solid raw materials, solid powders are generally fed through screw conveyors, pneumatic conveying devices, etc. Most solid powder feeding systems involve structures such as hoppers, silos, and material conveying pipelines.
[0004] In existing automatic feeding devices, powder easily clogs the outlet, sticking to the walls and preventing smooth material flow, leading to downtime for maintenance. In severe cases, abnormal equipment pressure poses a potential explosion risk. To address this problem, operators often use iron bars to strike the outer wall of the equipment, which not only increases their workload but also their exposure to the chemical plant environment. Therefore, solving the problems of powder clogging and difficult material flow is essential. Utility Model Content
