Dry powder recycling machine

Abstract

The invention discloses a dry powder recycling machine. The dry powder recycling machine comprises a work table and a recycling cylinder; the recycling cylinder is provided with a jet hole and comprises a filter cylinder and a cylinder cover, the bottom of the filter cylinder is conical, a conical opening of the filter cylinder is a powder outlet, and a butterfly valve is arranged on the conical opening; a negative pressure pipe is arranged on the cylinder cover and is connected to an external negative pressure generator; a motor is installed in the cylinder cover, an output shaft of the motor is connected to an installing plate through a connecting pipe, and a filter element connecting rod is installed below the installing plate; a filter element is installed on the filter element connecting rod; a flow guide cover is arranged below a cylinder body lower flange; a ventilation hole is formed in the upper part of the connecting pipe and communicates with the cylinder cover and the flow guide cover. According to the machine, the motor drives the filter element to rotate, dry powder on the filter element can be cleared, and the service life of equipment can be prolonged; the flow guide cover is arranged additionally for improving the recycling efficiency of the dry powder; whether recycled fire extinguishers are pressurized are distinguished and treated, the energy is saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production equipment for fire fighting equipment, in particular to a dry powder recovery machine. Background technique [0002] Dry powder fire extinguishers are widely used in people's daily life. According to the GA95-2007 standard, dry powder fire extinguishers must be maintained every 2 years, and the steel cylinders of the fire extinguishers must also undergo a hydraulic test. Before the hydrostatic test, the old fire extinguishing dry powder agent must be emptied, also known as dry powder recovery. After the hydrostatic test is qualified, reload the dry powder. [0003] The dry powder recovery method in the prior art is to directly open the mouth of the fire extinguisher and dump the old dry powder inside. Because the dry powder is small and light, it will cause dust pollution during the dumping process. People who have been engaged in this type of work for a long time will suffer Cause respirator...

Problems solved by technology

[0003] The dry powder recovery method in the prior art is to directly open the mouth of the fire extinguisher and dump the old dry powder inside. Because the dry powder is small and light, it will cause dust pollution during the dumping process. People who have been engaged in this type of work for a long time will suffer Cause respiratory and other diseases and affect human health

And the dust floating into the atmosphere will also cause environmental pollution

Patent No. "200720141399.0" is a utility model patent titled "Recovery and filling device for dry powder fire extinguishers", which discloses a recovery and filling device for dry powder fire extinguishers. The device does not have a self-cleaning function, the service life of the equipment is short, and it does not distinguish whether the recovered fire extinguisher is under pressure, the work efficiency is low, and the efficiency of dry powder recovery is low
