As we all know, shot blasting machine is a kind of machine which clean the metal workpieces surface with the high-speed impeller projectile the steel shot. After clean the workpieces the dust, oxide scale and rust will fall down into the machine. whether the shot blasting machine should take explosion-proof measures and how to achieve environmental protection are the most important things. QGMA Machinery will solve those problems for you.
Is the shot blasting machine to take explosion-proof measures?
Whether the shot blasting machine should take some explosion-proof measures depends on the use environment of the equipment, the type of the work piece and the application requirements and so on. If the work piece are the aluminum alloy, magnesium alloy, titanium alloy will produce explosive dust in the process of shot blasting, or if there is explosion danger in some environmental conditions like in a certain concentration, high temperature, static electricity, friction and other conditions.It is necessary to take some explosion-proof measures to avoid or prevent explosion. If the shot blasting machine takes the explosion-proof measures, the concrete measures are as follows:
(1) .The inner surface of the shot blasting machine dust collector is not painted, the body has the outlet, and the conductive filter bag containing metal wire should be selected on the dust-removing cloth bag. In addition, on the dust pipe, the flange is earthed, and one-way reverse check valve is installed at the inlet side of the duct.
(2) .Grounding treatment of shot blasting machine, dust collector, electrical cabinet, selection of explosion-proof type for fan motor and installation of leakage protector for circuit breakers in various parts.
(3).The edge angle of the bottom of dust collector is greater than 60 degree; dust collector adopts dust discharge valve type no dust accumulation.
How to make the shot blasting machine have a high cleaning effect?
In addition, pulse filter cartridge dust collector is suitable for shot blasting machine? In order to have good cleaning effect of shot blasting machine, we need to do: first, the quality of the equipment should be good, at least the quality should be qualified, second, the shot blasting parameters should be reasonable and appropriate, and the third is the use of the appropriate projectile. To achieve these three points, in order to make the blasting machine has a good cleaning effect. Pulse filter cartridge dust collector, which is suitable for shot blasting machine, and can be matched with various types of shot blasting machine.
How does the shot blasting machine meet environmental protection requirements?
Shot blasting cleaning process produces dust, dust distributed to the workshop air, serious pollution of the surrounding environment. In order to meet the environmental protection requirements, the shot blasting machine is mainly on the part of the dust collector. Specifically, it is necessary to filter material of good quality and not cause environmental pollution, QGMA Machinery filter cartridge adopt the Donaldson technology. The cleaning efficiency can up to 99.9% and the dust removal system can operate normally and stably. In addition, the dust collector should be matched with the shot blasting machine, so that the dust can be recovered well, and then the purpose and requirement of environmental protection can be achieved.
