Abstract
The utility model relates to a centrifugal casting wet paint spraying device which comprises a paint pipe and a compressed gas pipe; the paint pipe is sleeved in the compressed gas pipe; the inner diameter of the compressed gas pipe is larger than the outer diameter of the paint pipe; and the outer wall of the paint pipe is provided with a heating device. When the paint pipe sprays paint, the heating device heats the wet paint in the paint pipe and simultaneously the heating device heats the compressed gas in the compressed gas pipe, so that the wet paint has a certain temperature; in addition, when in paint spraying, due to the temperature of a mould and hot air blowed by the heated compressed gas, after the wet paint is sprayed into the cavity of the mould, the water in the wet paint is quickly evaporated, the drying time is greatly shortened and the production efficiency is improved; the mould does not need to be heated for drying paint, thereby reducing the service life of the mould and prolonging the service life of the mould; and when in paint spraying, the pre-heated compressed gas atomizes the wet paint with pressure on the spraying end of the paint pipe, the spraying spacing can be finely adjusted, the paint spraying is more uniform, the spraying quality is improved, and the casting quality is ensured.
Description
Technical field:
The utility model relates to the wet painting spraying device of a kind of centrifugal casting.
Background technology:
At present, the wet coating that centrifugal casting is used, its compactness, elevated temperature strength, uniformity, heat-proof quality and all better than dry-coated material with the binding ability of mould, but, the uniformity that wet coating sprays into mould is bigger with the device relation of the wet coating of spraying, the drying that secondly wet coating sprays into behind the mould must rely on higher mold temperature baking, can reduce 50-100 ℃ of mold temperature behind the usually wet coating bone dry, to guarantee that so the quality of foundry goods just must improve the temperature of mould, this method cost height, complex process, and the mold temperature height also can reduce the service life of mould, if allow wet coating air dry, need the regular hour, production efficiency is lower.
The utility model content:
The purpose of this utility model provides the wet painting spraying device of a kind of centrifugal casting, can accelerate dry wet coating.
A kind of centrifugal casting painting spraying device that wets, wherein: comprise coating pipe, compression gas pipe, the coating pipe is set in the compression gas pipe, and the internal diameter of compression gas pipe is greater than the external diameter of coating pipe, and the outer wall of coating pipe is provided with heater.
The described centrifugal casting painting spraying device that wets, wherein: described heater is a resistive heater, the resistive heater winding is on the outer wall of the one section coating pipe that is positioned at compression gas pipe inside.
The described centrifugal casting painting spraying device that wets, wherein: the spraying end of coating pipe connects cone nozzle, has the gap between the outlet side oral area of cone nozzle and compression gas pipe.
The utility model will reach following technique effect after adopting technique scheme:
The centrifugal casting of the present utility model painting spraying device that wets, coating pipe and compression gas pipe forming sleeves, the outer wall that is positioned at one section coating pipe of compression gas pipe inside is provided with heater, so, the coating pipe is when spraying, heater is to the wet coating heating in the coating pipe, and simultaneously, heater also heats the Compressed Gas in the compression gas pipe, on the one hand, make wet coating have certain temperature, after the temperature of mould itself and the Compressed Gas blowing hot-air of heating when adding spraying, wet coating are sprayed onto in the die cavity, moisture in the wet coating evaporates rapidly, shortened drying time greatly, enhance productivity, and mould does not need to carry out because of dry paint hyperthermic treatment, reduce the mould serviceability temperature, prolong die life, on the other hand, the Compressed Gas of preheating atomizes to the wet coating that coating pipe spraying end has pressure during spraying, the spraying gap can be finely tuned, can make the coating spraying more even, improve coating quality, the quality of foundry goods is guaranteed.
Description of drawings:
Fig. 1 is the structure principle chart of the wet painting spraying device of centrifugal casting of the present utility model.
The specific embodiment:
The centrifugal casting of the present utility model painting spraying device that wets, as shown in Figure 1, comprise coating pipe 1, compression gas pipe 2, coating pipe 1 is connected in the internal thread at compression gas pipe 2 corresponding connecting portions 62 places by the external thread sleeve at connecting portion 61 places, coating pipe 1 is set in the compression gas pipe 2, coating pipe 1 is socketed on the outer wall at the position in the compression gas pipe 2 and is arranged with ceramic insulating tube 31, evenly be arranged with resistive heater 3 on the ceramic insulating tube 31, the external diameter of the integral body that coating pipe 1, ceramic insulating tube 31, resistive heater 3 constitute is less than the internal diameter of compression gas pipe 2 corresponding positions.
Coating pipe 1, compression gas pipe 2 can adopt seamless steel pipe, aluminum pipe or copper pipe.
