A special vacuum cleaner for a purification workshop

Abstract

The invention relates to a special dust collector for a clean room and belongs to the fields of biological medicine, precision machining and machinery. By arranging a dust collecting system of the special dust collector outside the clean room completely and by using an air storage tank which has certain volume and is pumped to certain vacuum degree through a mechanical pump to provide suction force, various dusts and pollutants in the clean room can be sucked to the outside of the clean room flexibly and efficiently, and no secondary pollution can be caused. By means of joint effect of the mechanical pump and the air storage tank, working pressure of the special dust collector has a wide adjustable range, the suction force can be set and adjusted flexibly, and a suction head and a suction pipeline can be switched freely. Meanwhile, device maintaining is simple and efficient. By means of the special dust collector, various pollutants can be removed efficiently, and local cleaning work in the clean room is greatly facilitated.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a special vacuum cleaner for purification workshops, which can be used in purification workshops in the fields of biology, medicine and electronics. Background technique [0002] Purification workshop (also known as clean workshop) is an indispensable work platform for modern industry, especially in the high-tech field. It enables products to be produced and manufactured in a good environmental space that is not affected by external conditions, thereby avoiding air pollution in traditional workshops. Particles, dust, bacteria, viruses, humidity, airflow and other unstable factors interfere with product quality. The purification environment of the workshop can be achieved by means of filtration, adsorption, chemical catalysis, etc. in conjunction with mechanical ventilation or electrostatic field "electrophoresis". However, some local locations and equipment must be cleaned with a va...

AI Technical Summary

Problems solved by technology

In addition, the vacuum cleaner body itself has a large surface area, which will also absorb a large amount of pollutants.

These will cause secondary pollution

[0005] (2) cannot directly attract large particles

General vacuum cleaners are limited by the dust collection mechanism and the size of the body, the dust suction force is only 0.1-0.2Kg / cm2, it is difficult to suck up large particles of pollutants

At the same time, since the dusty atmosphere will directly contact the mechanical moving parts of the fan blades or vacuum pump, if large particles are inhaled, it is easy to cause damage to these parts in the vacuum cleaner.

Therefore, general vacuum cleaners cannot directly attract large particles.

[0006] (3) The working pressure is uncontrollable or the adjustment range is narrow

However, the problem of attractiveness and work pressure adjustment has not been effectively resolved

U.S. patent US8371912 uses independent modules to separately package the components of the vacuum cleaner and the purification workshop, and European patent EP0528696B1 places the mechanical power part of the vacuum cleaner outside the purification workshop, which completely eliminates the problem of secondary pollution and increases the working pressure of the vacuum cleaner to a certain extent The adjustable range, but the inhalation of large particles has not been improved, and the absorption of particles of different particle sizes and different distances is very inflexible
