Problems solved by technology

[0033] The main defects of the popular explosion-proof enclosures are: the hardness of the explosion-proof surface is low (about HRC15), the corrosion resistance is poor (2-6 months after phosphating), it is easy to explode, the life is short, the function is single, and the explosion-proof switch does not prevent Unauthorized power transmission, prevent unauthorized opening operation function

Embodiment Construction

[0134] Flameproof enclosures for remanufactured switches (eg Figure 5 Shown) the specific way:

[0135] Decontamination of waste flameproof enclosures: in Figure (8), buy a car cleaning equipment (82), such as a "black cat" cleaning machine, make a cement platform, the middle of which is high and the sides are low, and the waste flameproof enclosures (81) Put it on the platform, wash it with a cleaning machine, the waste water flows from the platform to the pool (83) (waste water treatment device) for sedimentation and filtration, clean water is recycled, and after several times of recycling, replace with new water, and the recovered old water is sent to sewage treatment Station treatment, not random discharge. Frequently dig pool sludge and clean the pool. After the explosion-proof shell is cleaned, it is dried and sent to the next process. It can also be flushed with compressed air. Clean heavily polluted parts with aqueous solution. Oxyacetylene flame roasting can be ...

Abstract

A process for re-create the flame-proof hull characterized by that, a plurality of techniques are combined using the surface engineering technology as a key process to realize the re-creation using the wasted flame-proof hull as the blank, producing the long life multifunctional flame-proof hull with high hardness of flame-proof surface and high corrosion-resisting performance. The method by the invention can realize the multiple repeated application for the flame-proof hulls.

Description

Technical field: [0001] The invention belongs to the field of industrial utilization of waste equipment. technical background [0002] Explosion-proof equipment occupies a pivotal position in the national economy. It is usually used in places with explosion hazards such as mines and chemicals. Flameproof equipment is made. The flameproof enclosure is a key component of flameproof equipment and a fundamental feature that distinguishes it from ordinary equipment. The explosion-proof enclosure is related to the safety of people's lives and the safety of a huge amount of property. The national standard has strict requirements on it, and it is easy to be damaged or scrapped during use. The damage and scrapping of the explosion-proof enclosure are mostly caused by the "explosion loss" of the explosion-proof surface. Flameproof equipment mainly includes flameproof switches, flameproof motors, flameproof transformers, flameproof small electrical appliances, etc. Flameproof enclo...
