Description

Heat-insulating dust-blocking plate for air suction opening of vacuum ion coating equipment

Technical Field

The utility model belongs to a vacuum ion plating equipment component, in particular to a heat-insulating dust guard of extraction opening of vacuum ion plating equipment.

Background

When vacuum coating equipment is used for coating a workpiece, in order to obtain a better coating effect, the vacuum coating equipment needs to be heated to provide energy, dust can be formed in a furnace after coating, and during vacuumizing, the dust can have certain influence on the service life of the vacuum equipment, so that the vacuum coating equipment is researched, developed and modified in order to prolong the service life of the vacuum equipment.

Disclosure of Invention

The utility model discloses it is not enough to lie in overcoming above-mentioned technique, provides a simple structure, and design benefit can insulate against heat the thermal-insulated dust board of extraction opening of the vacuum ion coating equipment of dust.

The utility model provides a technical scheme that technical problem adopted is: the utility model provides a dismantled and assembled thermal-insulated dust board of extraction opening of vacuum ion coating equipment, includes the furnace body, and characterized by welds the flange of extraction opening on the furnace body, then places thermal-insulated dust board in the flange of extraction opening, and thermal-insulated dust board is by sheltering from ring one, shelter from ring two and shelter from ring three and spliced pole welding one-tenth a whole, directly puts into the flange of extraction opening.

Compared with the prior art, the utility model, have following advantage: this kind of structural style's vacuum ion coating equipment's extraction opening keeps off dirt board that insulates against heat, made by the stainless steel, its simple structure, design benefit, it is rationally distributed, it does not have the structural defect who keeps off dirt board at thermal-insulated to traditional vacuum extraction opening, a mechanism that can keep off dirt that insulates against heat is designed, it appears and can block the heat loss, it gets into air exhaust system to reduce the dust, the clearance is conveniently dismantled, air exhaust system's environment is improved, and its low in manufacturing cost, therefore it has been said that it has possessed multiple advantage, be particularly suitable for popularizing and applying in the vacuum coating field, its market prospect is very wide.

Drawings

The following description is made in detail by way of example with reference to the accompanying drawings.

FIG. 1 is a body view of an insulating dust barrier.

Fig. 2 is a main body diagram of the embodiment of the present invention.

In the figure: 1-an extraction opening flange; 2-heat insulation dust board; 2-1-shielding ring one; 2-2-shielding ring II; 2-3-shielding ring III; 2-4-connecting column; and 3, furnace body.

Detailed Description

The following description will be made of embodiments of the present invention with reference to the accompanying drawings, as shown in fig. 1 and fig. 2: a heat-insulating dust guard plate for an air exhaust opening of vacuum ion plating equipment comprises a furnace body 3 and is characterized in that an air exhaust opening flange 1 is welded on the furnace body 3, and a heat-insulating dust guard plate 2 is formed by welding a shielding ring I2-1, a shielding ring II 2-2, a shielding ring III 2-3 and a connecting column 2-4 into a whole.

The use method of the utility model is that the heat insulation dust baffle 2 is placed in the air exhaust flange 1, a small amount of clearance is left between the excircle size of the shielding ring III 2-3 and the inner diameter size of the air exhaust flange 1, and the whole body is only required to be put in during installation without the auxiliary fixation of other parts.

Claims (1)

1. The utility model provides a vacuum ion coating equipment's bleeder vent heat-insulating dust board, includes furnace body (3), characterized by welds bleeder vent flange (1) inside furnace body (3), and heat-insulating dust board (2) are by sheltering from ring one (2-1), shelter from ring two (2-2) and shelter from ring three (2-3) and spliced pole (2-4) welding as a whole, and heat-insulating dust board (2) are made circularly, and the maximum external diameter size of heat-insulating dust board (2) is less than the internal diameter size of bleeder vent flange (1) slightly to make heat-insulating dust board (2) directly place in bleeder vent flange (1).
