Explosion-proof power distribution cabinet for dust workshop

Abstract

The invention discloses an explosion-proof power distribution cabinet for a dust workshop, and the cabinet comprises a cabinet body, the cabinet body is internally provided with a mounting cavity and a functional groove, the inner side wall of the mounting cavity is fixedly connected with a heat conduction plate, and the functional groove is internally provided with a self-adjusting pumping heat dissipation mechanism; and the self-adjusting air pumping heat dissipation mechanism comprises a gear motor, the gear motor is fixedly connected with the inner side wall of the functional groove, an output shaft of the gear motor is fixedly connected with a rotating shaft, the rotating shaft is in interference fit with a rotating block, and an electromagnet is arranged in the rotating block. The power distribution cabinet has the advantages that the pumping amount can be adjusted according to the temperature, the probability that dust enters the power distribution cabinet is reduced, the probability that the dust enters the power distribution cabinet is greatly reduced by matching with filtering of the first filter screen, the dust amount in the power distribution cabinet is reduced, the explosion risk is avoided, meanwhile, the temperature in the power distribution cabinet can be better controlled, and the power distribution cabinet is more convenient to use. And dust in the workshop is removed to a certain extent, and workshop safety is guaranteed.

Description

Technical field [0001] The invention involves the technology field of explosion -proof power -proofing cabinets, especially for explosion -proof power distribution cabinets for a dust workshop. Background technique [0002] Electricity is one of our commonly used energy. In the process of production and life, electrical energy needs to be used. The power distribution cabinet is the last -class device of the power distribution system. The distribution cabinet is the collective name of the motor control center. The load is relatively decentralized and the circuit is small. The power distribution cabinet will allocate the electric energy of a certain circuit of the upper -level power distribution equipment to the nearest load. This level of device response to the load provides protection, monitoring and control. In the production workshop, a power distribution cabinet is generally equipped for power supply to the equipment in the workshop. [0003] In the existing technology, during...

Problems solved by technology

[0003] In the prior art, during the use of the power distribution cabinet, a certain amount of heat dissipation is required for the power distribution cabinet. The existing power distribution cabinet is often directly ventilated and radiated, and in the dusty workshop, such as the cement and flour processing workshop The air in the workshop contains a certain amount of dust. Direct ventilation and heat dissipation may cause dust accumulation in the power distribution cabinet. When the dust reaches a certain level, there may be a risk of explosion
