Abstract
The invention relates to an explosion-proof controller based on a mining motor. The explosion-proof controller comprises a controller integrated circuit, controller lead wires, and a combined type explosion-proof housing. The controller integrated circuit is arranged inside the combined type explosion-proof housing that is composed of an upper housing and a lower housing; space between the upper housing and the lower housing is filled with an insulated rubber and the upper housing and the lower housing are fixedly connected with an explosion-proof bolt; lead wire holes are arranged on the upper housing; the controller lead wires are connected with an external control circuit by the lead wire holes; and the lead wire holes are filled with sealing insulation rubbers. According to the invention, the explosion-proof controller has advantages of simple structure, low manufacturing cost, convenient installation, good explosion-proof performance, high security coefficient, and wide application range.
Description
Technical field
The present invention relates to a kind of explosion-proof controller based on mine motor.
Background technology
Fire-proof motor is widely used in the inflammable and explosive occasions such as oil, chemical industry and military industry field.At these inflammable and explosive dangerous situations, use sometimes the Handling devices such as conveyer belt, its drive motors mostly is fire-proof motor, and the controller of handling this motor becomes key equipment.When there is short trouble suddenly in controller circuitry, thereby may burning out controller circuit board, excessive electric current produces spark or heating, cause burning or blast, lose fail safe.The circuit that existing explosion-proof controller all be take in change controller is controlled as strategy, does like this scope of application of not only having dwindled product, has also increased production difficulty, has improved manufacturing cost.
Summary of the invention
The object of the invention is to, provide a kind of coefficient of safety high, wide accommodation, production difficulty is low, the explosion-proof controller based on mine motor of low cost of manufacture.
The object of the invention is to be achieved through the following technical solutions: a kind of explosion-proof controller based on mine motor, comprise controller IC and controller lead-in wire, it is characterized in that: be also provided with Combined anti-explosion housing, described controller IC is positioned at Combined anti-explosion housing, described Combined anti-explosion housing mainly consists of upper shell and lower house, between described upper shell and lower house, be filled with electro-insulating rubber, and be fixedly connected with by explosion-proof bolt, described upper shell is provided with fairlead, described controller lead-in wire is connected with extraneous control circuit by fairlead, fairlead place is filled with sealed insulation rubber.
The present invention is filled with the Combined anti-explosion housing of electro-insulating rubber by employing, make the spark that may produce because of short circuit in controller cannot light explosive mixture around, even the inner small blasting that occurs of controller, because the existence of outside explosion-proof casing also can intercept the effusion of spark, thereby can fully guarantee the fail safe of controller, and greatly improve its accommodation.
The present invention is simple in structure, and functional reliability is high, and production difficulty is low, and low cost of manufacture is easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing, the present embodiment comprises controller IC 6, controller lead-in wire 1 and Combined anti-explosion housing, described controller IC 6 is positioned at Combined anti-explosion housing, described Combined anti-explosion housing mainly consists of upper shell 2 and lower house 4, between described upper shell 2 and lower house 4, be filled with electro-insulating rubber 3, and be fixedly connected with by explosion-proof bolt 5, described upper shell 2 is provided with fairlead, described controller lead-in wire 1 is connected with extraneous control circuit by fairlead, and fairlead place is filled with sealed insulation rubber.
During work, after being delivered to controller by the electric current in external circuit, controller lead-in wire 1 again control action is fed back to external circuit, if occur suddenly in circuit, short circuit causes the electric current in controller lead-in wire 1 excessive, puncture the electric capacity of controller IC 6, thereby produce spark and heat, the filled rubber 3 meeting obstruct sparks at sealing position and heat is inflammable and explosive environmental dissemination towards periphery, even if controller is inner there is blast among a small circle, because the existence of Combined anti-explosion housing also can stop it to light explosive mixture around.The present embodiment adopts sealing and two kinds of explosion-proof forms of flame proof, and explosion-proof performance is good, meets the requirement of explosion proof of relevant criterion; In addition, it is simple in structure, and low cost of manufacture is easy for installation, applied widely.
