Control device based on flexible triggering of silicon controlled rectifier

Abstract

The invention discloses a control device based on the flexible triggering of a silicon controlled rectifier, and the device comprises a flue pipe and a motor disposed outside the flue pipe. The interior of the flue pipe is provided with a rotating shaft, wherein one end of the rotating shaft is fixed on the motor, and the other end of the rotating shaft is fixedly provided with a fan blade. The blade surface of the fan blade faces the mouth of the flue pipe, and the mouth of the flue pipe is provided with a solenoid valve. The device also comprises a silicon controlled rectifier switch and twoflexible pipes, and the silicon controlled rectifier switch is electrically connected with the solenoid valve. Two sides of the flue pipe are respectively provided with through holes, and the two through holes are located at the upper part of the flue pipe. Two sides of the flue pipe are respectively provided with a Venturi tube, and a throat part of each Venturi tube is provided with a water pipe. A water tank is disposed below the Venturi tubes, and the water tank is connected with the water pipes. One end of each Venturi tube is communicated with one through hole, and the end of each Venturi tube is connected with one flexible pipe. According to the scheme of the invention, water, dust and air are integrated to form water mist through the Venturi tubes, and the water mist is sprayed tothe interior of a workshop, thereby reducing the dust in the workshop, and also increasing the humidity of the workshop.

Description

technical field

[0001] The invention belongs to the technical field of thyristors, in particular to a control device based on sensitive trigger thyristors. Background technique

[0002] With the development of high and new technologies such as electronics, the concentration of pollutants in the environment may often cause electrical drift or instability to products. And the concentration of its gaseous pollutants must be less than 1ppt in the factory building of making electronic products, therefore, in order to filter and remove dust, the existing method all is to arrange chemical filter at the air inlet of the fan on the ceiling of the factory building to reduce dust, and For the current conventional chemical filter, in the initial state, its effect of adsorbing organic pollutants is better, and clean air with lower pollutant concentration can be obtained, but as the use time is prolonged, its impurity removal effect will become more and more serious. The worse it is, the...
