Description
Technical field
The present invention relates to explosion-proof control technology field, specifically belong to one and be convenient to cooling anti-explosion electric control box.
Background technology
Existing control cubicle great majority can not explosion-proofly be merely able to use in the good situation of environment, under image-stone oil mining environment, use and just have larger potential safety hazard.Oil gas is a kind of combustibles, as long as meet three conditions of burning, and will breaking out of fire accident.As everyone knows, three of burning conditions are: combustible, oxidizer, ignition point.Electrical control cabinet easily produces electric spark or localized hyperthermia (ignition point) in use, and in air, has a large amount of oxygen (oxidizer), when using in chemical industry and mining environment, is great security threat.Existing general use positive pressure explosion-proof cabinet carries out explosive-proof protector to electric equipment.Common positive pressure explosion-proof cabinet controls that degree is low automatically, and sealing is poor, uses inconvenience.Also have also main by using epoxy resin encapsulated, make electrical control gear internal circuit, element and outside isolated, prevent that dust, moisture from entering electric apparatus control apparatus, to reach explosion-proof, but this structure equipment that is not easy to regulates examination, safeguards, cost of manufacture mounting process complexity, just cannot be used once its inner control element damages.
Summary of the invention
The object of this invention is to provide one and be convenient to cooling anti-explosion electric control box, overcome the deficiencies in the prior art, adopted in positive pressure explosion-proof cabinet controller is set, automatically adjusted temperature, pressure and the air output of positive pressure explosion-proof cabinet, improve the level of automatic control, simplified manual operation; The Seal Design at cabinet door place has improved the sealing of positive pressure explosion-proof cabinet.
The technical solution used in the present invention is as follows:
One is convenient to cooling anti-explosion electric control box, comprises casing, and casing is provided with fixed cap outward, in described casing, be provided with electric component cabinet is installed, cabinet is fixed on box inside face, and cabinet lateral wall is provided with air inlet and air outlet, is respectively equipped with a butterfly valve in air inlet and air outlet; On described cabinet, be also provided with a relief hole, relief hole is provided with elastic sealing cover, in described cabinet, is provided with circulating fan, the filter in circulating fan and cabinet outside and cooler is connected in series and be connected formation circulation canal with cabinet; Described cabinet outside is provided with enclosing cover, and described cabinet lower end is provided with incoming line, line outlet and action bars, and action bars is connected with cabinet internal short-circuit device.
In described cabinet, be also provided with controller, temperature sensor and pressure sensor, controller is connected with butterfly valve, temperature sensor and pressure sensor respectively.
The junction of described cabinet and enclosing cover is provided with waveform seal groove, is provided with rubber sheet gasket in seal groove.
Between described fixed cap and casing edge, be provided with spring carrier arm.
Described elastic sealing cover lower end is connected with cabinet by spring, and upper end is provided with pouring weight, and elastic sealing cover and cabinet contact-making surface are rubber contact-making surface.
Hydroxide two ferrous solutions are housed in described filter.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention adopts in positive pressure explosion-proof cabinet controller is set, and automatically adjusts temperature, pressure and the air output of positive pressure explosion-proof cabinet, has improved the level of automatic control, has simplified manual operation; The Seal Design at cabinet door place has improved the sealing of positive pressure explosion-proof cabinet; Adopt air filtration deoxidation method simultaneously, effectively reduce the oxygen content in cabinet, further improve the fail safe using; Also have because mostly situation lower cabinet body is in sealing state, in cabinet, after gas heat absorption, heat is difficult to distribute, and causes potential safety hazard, and the present invention is connected with cooler on cabinet at the same time and can ensures effectively to carry out cooling down to cabinet, guarantees to use safety.
