Description
Technical Field
The utility model relates to a dustless spraying device.
Background
At present, in the steel-making process of a steel plant, in order to track the whole process of steel billets, the end faces of the steel billets need to be marked by spraying numbers, however, in a dusty environment, dust easily enters a spray gun to cause the blockage of a gun body.
Because most of spraying equipment is arranged in a dangerous area, if the problem that a gun body is blocked occurs, manual maintenance is needed, great labor intensity and potential safety hazards exist, and based on actual conditions of the site and the working environment of operation and maintenance workers, the spraying equipment capable of dealing with multiple dust working conditions is needed.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome prior art's defect, provide a dustless spraying device, it can effectively avoid the dust to get into in the spray gun main part, and then avoids the spray gun main part to appear blockking up and the condition of mechanical wear because of the dust gets into.
In order to solve the technical problem, the technical scheme of the utility model is that: a dust-free spray coating apparatus comprising:
a housing provided with an ejection port and a compressed air blowing port adapted to allow compressed air to enter the housing therethrough;
the spray gun body is arranged in the shell and is completely surrounded in the shell, and a nozzle of the spray gun body is opposite to the spraying port.
Furthermore, the dust-free spraying device also comprises a spray gun support, and the shell is arranged on the spray gun support.
Further to facilitate connection between the external component and the lance support, a flange is connected to the lance support and adapted to be connected to the external component.
Further, in order to reduce the weight and reduce the inertia in the spraying process, the material of the spray gun support is light.
Further, the light material is an aluminum alloy.
Further, in order to facilitate the communication of the compressed air delivery pipe with the compressed air port, the compressed air blowing port is provided with a joint, and the joint is suitable for being connected with the compressed air delivery pipe.
Further in order to conveniently disassemble the shell to clean the shell or the interior of the spray gun main body, the shell comprises two half shells buckled with each other, and the two half shells are connected into a whole through bolts.
Further, the shell is made of stainless steel.
Further, the three-way valve set of the spray gun body is suitable for accessing water or air or paint.
After the technical scheme is adopted, compressed air is blown into the shell through the compressed air blowing-in port, so that the internal air pressure of the shell is always greater than the external air pressure of the shell, dust is prevented from entering the shell and the inner part of the spray gun main body from a gap of the shell, and a dust-free effect is achieved; compressed air in the shell flows through the spray gun main body and is discharged from a gap of the shell, so that the effect of cooling the spray gun main body is achieved to a certain extent, and the over-high temperature of the spray gun main body in the working process is effectively prevented; the utility model discloses a dustless spraying device range of application is wide, is fit for various operating modes, especially many dust operating modes, and stability is high, whole stable in structure, and the fault rate is lower, has greatly reduced artifical input.
Drawings
FIG. 1 is a plan view of a dust-free coating apparatus of the present invention;
fig. 2 is a side view of the dust-free spraying apparatus of the present invention.
Detailed Description
In order that the present invention may be more clearly understood, the following detailed description is given with reference to the accompanying drawings.
As shown in fig. 1 and 2, a dust-free coating apparatus comprises:
a housing 1, the housing 1 being provided with an ejection port 2 and a compressed air blowing port adapted to allow compressed air to enter the housing 1 therethrough;
and the spray gun body 3 is arranged in the shell 1 and is completely enclosed in the shell 1, and a nozzle of the spray gun body 3 is opposite to the spray port 2.
In the present embodiment, the housing 1 not only provides a certain air tightness, but also provides durability for the entire dust-free spraying apparatus.
Specifically, compressed air is blown into the shell 1 through the compressed air blowing-in port, so that the internal air pressure of the shell 1 is always greater than the external air pressure of the shell 1, thereby preventing dust from entering the shell 1 and the spray gun body 3 from gaps of the shell 1, and further achieving the dust-free effect; compressed air in the shell 1 flows through the spray gun main body 3 and is discharged from a gap of the shell 1, so that the spray gun main body 3 is cooled to a certain extent, and the over-high temperature of the spray gun main body 3 in the working process is effectively prevented; the utility model discloses a dustless spraying device range of application is wide, is fit for various operating modes, especially many dust operating modes, and stability is high, whole stable in structure, and the fault rate is lower, has greatly reduced artifical input.
As shown in fig. 1 and 2, the dust-free spraying device further comprises a spray gun support 4, and the housing 1 is mounted on the spray gun support 4.
To facilitate connection between the external components and the lance holder 4, a flange 5 is attached to the lance holder 4, the flange 5 being adapted to be connected to the external components, as shown in figures 1 and 2. The external component may be an industrial robot or other equipment.
In this embodiment, the material of the spray gun support 4 is a light material so that the weight can be reduced to reduce the inertia during the spraying process. The light material can be selected from aluminum alloy.
As shown in fig. 1 and 2, in order to facilitate the communication of the compressed air duct with the compressed air port, the compressed air blowing port is fitted with a fitting 6, and the fitting 6 is adapted to be connected with the compressed air duct.
As shown in fig. 1 and 2, in order to facilitate disassembling the housing 1 to clean the housing 1 or the spray gun body 3, the housing 1 includes two half shells fastened to each other, and the two half shells are connected into a whole by bolts.
