Description

Outer wall insulation structure of vacuum drying tank

Technical Field

This paper belongs to the technical field of drying equipment for the transformer, concretely relates to vacuum drying jar's outer wall insulation construction.

Background

The vacuum drying equipment adopting the heat conduction oil as the heat source is suitable for carrying out vacuum drying treatment on coils, bodies and the like of electrical equipment such as transformers, motors, reactors, mutual inductors and the like. The tank body in the vacuum drying equipment using heat-conducting oil as heat source is formed from tank door, tank body flange and in-tank heating calandria, and the outer wall of the tank must be laid by mineral wool heat-insulating material, its thickness is 150mm, and then it is armored by using colour steel plate whose thickness is 0.5 mm. The drying system comprises a fan, an air duct, a heat-conducting oil discharge pipe and the like, wherein the heat-conducting oil pipe is used for heat preservation by rock wool and is armored by a stainless steel sheet. The mineral wool material mainly plays a role in heat preservation and heat insulation in hot air circulation drying equipment. In order to further reduce the energy consumption, one side of the mineral wool is provided with an aluminum foil.

Adopt the drying equipment of conduction oil as the heat source, in the use, in the inevitable conduction oil spills over infiltration rock wool, under high, microthermal repeated action, the conduction oil can be atomized, reaches certain degree when the concentration of atomizing, and equipment shell or aluminium foil ground connection are bad when arousing electrostatic discharge, can catch fire even the explosion incident takes place. In order to ensure the safety of the working environment of workers and reduce the loss of companies, a partial improved structure of an insulating layer on the outer wall of a tank body of vacuum drying equipment, which adopts heat conduction oil as a heat source, is provided, and the electrostatic spark caused by poor grounding of the equipment can be eliminated, so that the fire accident is caused.

SUMMERY OF THE UTILITY MODEL

Original vacuum drying equipment jar that adopts conduction oil as heat source includes vacuum tank jar door, jar internal heating calandria, wind channel, jar wall, tank bottoms, tank deck, mineral wool and aluminium foil, welds into a jar body with the steel sheet, and the jar wall is by the strengthening rib skeleton that square steel tube welding formed, and it is integrative to weld with the iron wire net bars between the square steel pipe to guarantee the planar roughness when laying aluminium foil and mineral wool, the calandria is as heat radiating element in the jar, and the conduction oil is as heat transfer medium.

According to the outer wall heat insulation structure of the vacuum drying tank, the aluminum foil with the grounding function is used for achieving the effects of energy conservation and consumption reduction on the one hand and providing the grounding point on the other hand, and the grounding piece extends around the aluminum foil so as to be used when the vacuum tank or the oil guide pipeline is manufactured.

The utility model provides an outer wall insulation construction vacuum drying pipe of vacuum drying jar includes vacuum jar door, jar interior heating calandria, wind channel, jar wall, tank bottoms, tank deck, ore rock wool and aluminium foil, jar wall inboard be equipped with ore rock wool, the one side of ore rock wool is equipped with the aluminium foil, the aluminium foil all be equipped with the grounding lug all around, the grounding lug be the extension in the aluminium foil outside.

The shape of grounding piece is rectangular shape, and the end of grounding piece is equipped with the riveting hole, and this paper plays energy saving and consumption reduction's effect on the one hand through the aluminium foil of taking ground connection, and on the other hand plays and provides the ground point effect, and the purpose of extending the grounding piece all around is when making vacuum tank or oil guide pipeline, when laying the mineral rock wool.

No matter how the mineral wool is cut, the ground point of the cut mineral wool can be ensured, the heat preservation and heat insulation effects of the mineral wool in the vacuum tank are reserved, and the static electricity removing function of the equipment is increased.

Interconnect between the grounding piece, the grounding piece links to each other through the riveting, and the mineral rock wool is laid on one side and is put up grounding piece interconnect, links together with equipment ground connection at last, and the cladding is laid the mineral rock wool aluminium foil of establishing the equipment shell like this and is formed complete ground net, and the material of grounding piece is aluminium.

Has the beneficial effects that:

this paper is through the aluminium foil of area ground connection, play energy saving and consumption reduction's effect on the one hand, on the other hand plays and provides the ground point effect, extend the purpose of ground lug all around when making vacuum tank or oil guide pipeline, when laying mineral wool, no matter how to tailor the mineral wool, the mineral wool after can both guaranteeing to tailor has the ground point, it keeps warm in the vacuum tank to have remain the mineral wool, thermal-insulated effect, the equipment destatic function has been increased, mineral wool lays on one side and couples together ground lug interconnect, link together with equipment ground connection at last, the mineral wool aluminium foil of the equipment shell of cladding setting up like this forms complete ground net, the material of ground lug is aluminium.

On the basis of original equipment, original parts are improved, new special functions are given to the original parts, the value added of the technology is realized, and a safer operation environment is created.
