The blasting diaphragm of diy laser fume extractor: The reverse arch rupture disk is a convex lateral medium made of a single layer of metal material, which will cause instability and damage after being loaded. The tool that is fixed on the concave surface after unsteady overturning has been cut or demolded. Because the unstable burst pressure is not sensitive to fatigue, it is suitable for pressure vessels with pulsating loads.

1. Fume extractor laser explosion-proof structure design measures The body structure is specially designed to prevent the flammable dust from the internal components of the dust collector from accumulating dust. All beams, partitions, etc. should be equipped with dust-proof panels, and the slope of the dust-proof panels Should be less than 70 degrees. Adjacent side plates should be welded to two adjacent side plates to prevent the angle between the two bucket walls from exceeding 70 degrees. Taking into account the phenomenon of ash bucket condensation due to abnormal operation and high dust humidity, the ash bucket is designed in the furnace Add steam pipe for heat preservation or tubular electric heater. In order to prevent shed material, a bin arm vibrator or air cannon is also required in each hopper.

2. The laser fume extractor price uses an anti-static filter bag inside. Because the high concentration of dust rubs against each other during the flow process, the dust and the filter cloth also rub against each other, which will generate static electricity, and the accumulation of static electricity will generate sparks and cause combustion. Pulsating dust cleaning method, the filter bag is made of polyester needled felt, because the polyester fiber needled felt is prone to insufficient static electricity, conductive metal wire or carbon fiber is added to the filter bag cloth, and the filter bag is connected to the porous plate through the steel frame , Connected to the workshop grounding grid through the shell. For anti-blowing and dust-removing filter bags, a variety of anti-static products such as MP922 have been developed. It is very effective.

3. It is very important to set up safety holes (valves) to limit the explosion in the bag filter and not expand in other directions. It is very important to set up safety holes and necessary fire fighting equipment. The purpose of setting safety holes is to limit the scope of the explosion and reduce the number of explosions, rather than setting safety holes to prevent explosions. Dust collectors for explosive dust treatment are equipped with safety exits for operation methods.

4. In the precipitator that handles the exhaust gas produced by certain flammable and explosive metal dust, the burned dust may enter the box together with the airflow of the air duct, causing the dust accumulated on the filter cloth to catch fire and cause an accident.
