Energy-saving explosion-proof drying furnace and its drying monitoring system

Abstract

The invention relates to an energy-saving explosionproof drying furnace and a monitoring system thereof. The drying furnace is provided with a furnace body, a heating element, a trolley and a chimney, wherein the furnace body is provided with a heating chamber body; the top of the furnace body is provided with a circular hot-air generator; the heating element is positioned in the heating chamber body; the chimney is sleeved with a preheating sleeve communicated with the heating chamber body; and the bottom of the furnace body is provided with a trolley lifting mechanism. The furnace has a rational and novel structure, a unique air channel design, and is provided with the complete drying automation monitoring system, thereby having the advantages of high heat energy utilization rate, convenient operation, labor conservation and quick drying speed, ensuring that the whole drying process is effectively monitored and maintained in an optimal running state, particularly effectively eliminating the hidden trouble of a burning and explosion accident and effectively guaranteeing the safety of a person and equipment.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, in particular to an energy-saving explosion-proof drying furnace and a drying monitoring system for drying windings of high-voltage motors, low-voltage motors, transformers, small electrical appliances, etc. after being impregnated with insulating varnish. Background technique [0002] Motors and electrical equipment generally require post-insulation treatment after the coils are assembled. Most enterprises use vacuum-pressure impregnated insulating varnish, and the insulating varnish is solvent-based insulating varnish or solvent-free insulating varnish. Among them, the solvents in the solvent-based insulating varnish are xylene, alcohol, etc., which are basically all volatilized during drying, and the amount of escape is not less than 30%; the solvent-free insulating varnish uses styrene as a solvent, and its drying The amount of escape is between 10% and 20%. Alcohol, xylene, and sty...

Problems solved by technology

This may cause an explosion

[0005] (2) Lack of effective monitoring and control of the temperature and pressure in the furnace

The effect of two aspects causes the energy consumption ratio of the drying furnace to be only 15-30% (the national standard requires no less than 30%)

[0007] (4) Although the traditional drying furnace displays the temperature in the furnace, it has no functions such as control, alarm and automatic power-off, and problems such as excessive local temperature in the furnace are inevitable.

[0008] (5) The trolley loaded with the workpiece to be dried usually enters the furnace as a whole, and is driven by a motor or manpower through a sling to realize its entry and exit, which is not only inconvenient to operate, but also labor-intensive, labor-intensive, time-consuming, and labor-intensive, which affects work efficiency
