Spraying device for architectural decoration

Technical Field

The invention belongs to the technical field of appliances for applying plasticized substances on the surface of a building through the action of air pressure in the building decoration engineering, and particularly relates to a spraying device for building decoration.

Background

In the construction of architectural decoration engineering, a painting device is sometimes used to color paint, and paint is atomized and sprayed out by using air with a certain pressure, so that the paint is uniformly attached to a building. After the spraying operation is completed, the operation of the next process can be performed only after the coating is dried, thereby affecting the progress of the whole decoration construction. How to shorten the time required by drying after spraying is a problem which needs to be solved urgently at present.

Disclosure of Invention

The invention aims to provide a spraying device for architectural decoration, which aims to solve the problem that the drying time is longer after the spraying operation of the architectural decoration in the prior art.

In order to achieve the purpose, the basic scheme of the invention provides a spraying device for architectural decoration, which comprises a bracket, wherein the bracket is connected with a spray head and an air compression mechanism, the bracket is connected with a first cover body covering the spray head, one end of the first cover body, which is far away from the bracket, is connected with an annular heat conduction pipe, the bracket is connected with a vortex tube, an air inlet of the vortex tube is communicated with the air compression mechanism, a hot end air outlet of the vortex tube is communicated with an air inlet end of the heat conduction pipe, and an air outlet end of the heat conduction pipe and a cold end air outlet of the vortex tube are communicated with the spray.

The principle and the beneficial effect of the basic scheme are as follows: air with certain pressure generated by the air compression mechanism enters the vortex tube, hot air flow generated by the hot end of the vortex tube enters the heat conduction tube, so that the heat conduction tube and the hot air flow are subjected to heat transfer, the temperature of the heat conduction tube is increased, then the air in the heat conduction tube enters the air outlet end of the heat conduction tube and is sprayed out of the spray head together with the cold end air outlet of the vortex tube, and the air atomizes the coating at the spray head, so that coating spraying is generated and spraying is carried out. The heat that the heat pipe produced carries out the thermal radiation drying to the surface after the spraying to the drying on spraying surface is convenient to carry out subsequent construction operation with higher speed. The heat is generated by utilizing the compressed air required during spraying, an additional power source is not required to be arranged, and the structure of the spraying device is prevented from being complicated.

Further, the outer side of the first cover body is coaxially sleeved with a second cover body, a cavity is arranged between the first cover body and the second cover body, an air inlet of the cavity is communicated with an air outlet of a cold end of the vortex tube, and an air outlet of the cavity is communicated with the spray head together with an air outlet end of the heat conducting tube. The cavity is formed between the second cover body and the first cover body, so that air entering the cavity from the heat conduction pipe is mixed with air entering the cavity from a cold end air outlet of the vortex tube, the temperature of the air finally entering the spray head is proper, the condition that the temperature is too high or too low is avoided, and the performance of the coating is prevented from being influenced.

Further, the shape of the cross section of the heat conduction pipe is a hollow rectangle. The hollow rectangle can make the heat pipe carry out the area of heat radiation great to the spraying face to be favorable to improving the heating effect of heat pipe to the spraying face.

Further, the first cover body and the second cover body are both conical. The shape of the paint spray is conical when the paint is sprayed, so that the shapes of the first cover body and the second cover body are adapted to the shape of the paint spray, and the space occupied by the first cover body and the second cover body is optimized.

Further, the heat pipe is made of an aluminum alloy material. The aluminum alloy material has good heat-conducting property, thereby being beneficial to the rapid heat transfer between the heat-conducting pipe and hot air and reducing the heat loss.

Furthermore, a sliding block is connected to the support in a sliding mode along the vertical direction, and the spray head is statically connected with the sliding block. The movement of the sliding block drives the spray head to move vertically, so that the spray head is conveniently supported when moving, the moving track of the spray head is regular, and the sprayed area is conveniently adjusted.

Furthermore, a telescopic mechanism for driving the sliding block to vertically slide is connected to the support. The telescopic mechanism is arranged to drive the sliding block to move, so that the working difficulty of the sliding block during moving is reduced, and the working load of an operator is reduced.

Further, the telescopic mechanism is an air cylinder. The structure of cylinder is fairly simple, conveniently installs the setting.

The air compression mechanism is installed on the support 7, and the air compression mechanism in the embodiment is preferably an air compressor in the prior art. The air outlet of the air compression mechanism is communicated with the air inlet of the vortex tube 5 through a guide pipe.

The specific implementation process is as follows: air with certain pressure is introduced into the vortex tube 5 by opening the air compression mechanism, so that the pressurized air ejects hot air with increased temperature from a hot end air outlet 51 of the vortex tube 5 under the action of the vortex tube 5, and ejects cold air with reduced temperature from a cold end air outlet 52 of the vortex tube 5, the hot air enters the heat conduction tube 1 from an air inlet of the heat conduction tube 1 and enters the cavity 6 from an air outlet of the heat conduction tube 1, the hot air is in heat transfer with the heat conduction tube 1 when flowing in the heat conduction tube 1, the temperature of the heat conduction tube 1 is increased, and the heat conduction tube 1 is subjected to heat radiation. Meanwhile, the hot air and the cooling air entering the cavity 6 are mixed and then enter the spray head 4, and the coating is sprayed after being atomized, so that the coating is sprayed.
