When people fight fires, fire-fighting equipment is very important. With the rapid development of science and technology, the upgrading of fire-fighting equipment has brought unlimited vitality. There are many types of fire fighting equipment, from automatic control fire alarm systems, fixed fire extinguishing systems, fire extinguishers, vehicles and water supply equipment to fire extinguishing agents and flame retardant equipment. It can be said that the whole process covers the research of metallurgy, machinery, transmission, chemical engineering and other disciplines. Fire extinguisher filling machine is widely used in daily life, but do you know the use and operation of dry powder fire extinguisher filling machine?
The dry powder fire extinguisher filling machine includes a vacuum pump, a filling device and a control device. The filling device includes a main filling device and an auxiliary filling device. The main filling device is equipped with an upper plate, a lower plate, a sealing gasket and a powder inlet pipe and a gasket. It is fixed on the lower plate, and the lower plate is fixed on the upper plate. The secondary filling device has a filter box, a filter and a manual switch with a powder spray nozzle. The dry powder fire extinguisher filling machine has a simple structure and accurate filling measurement. Due to the secondary filling, the filter can be cleaned, so its energy consumption is low, no powder layer enters the atmosphere, and it does not pollute the air. At the same time, it can save fillers and reduce costs. The machine is small in size, simple in operation, and light in weight. It is suitable for filling all kinds of dry powder, especially for powder filling of dry powder fire extinguishers.
When there are two vent holes on the upper plate, the two holes are separated by a rubber band, and one hole is connected to the suction hole of the secondary filling equipment through a pipe. There is a manual valve between the two holes, and the other hole is connected to a solenoid valve communicating with the atmosphere, and the solenoid valve is controlled by a control device.
The filter box has a sealed box cover and a box body, the filter is installed on the bottom surface of the box cover, and the box cover is composed of filter paper and filter cloth or a ceramic filter. The box cover is provided with a vent hole, and the exhaust port is connected with a vacuum pump through a solenoid valve. The pipe between the exhaust port and the solenoid valve is provided with a solenoid valve and a second filter communicating with the atmosphere, and the solenoid valve is controlled by a control device.
