Embodiment 1

[0012] Example 1 Adjust the height of the bracket to adapt to the inner diameter of different pipelines

[0013] exist figure 1 Among them, the ① guide tube and ③ atomizing nozzle adapter are connected to the ② guide tube end cap through the pipe thread, and the atomizing nozzle (composed of ④ nozzle and ⑤ flow adjustment knob) is connected to the ③ atomizing nozzle through the pipe thread. The ⑥ bracket is connected with the hinged hole on the ② guide tube end cover by means of hinge support, ⑨ the roller is installed at the end of the ⑥ bracket, ⑦ butt joint is connected with the ② guide tube end cover through the pipe thread Connect with ⑧ rotary joint.

[0014] The supporting structure of the whole spraying device is composed of two brackets, which are connected and fastened by bolts of corresponding specifications. When in use, install each component in place according to the installation sequence described in this embodiment, and adjust the height of the supporting mech...

Embodiment 2

[0015] Embodiment 2 The adjustment of nozzle spraying flow rate and atomization effect

[0016] exist figure 1 Among them, the ① guide tube and ③ atomizing nozzle adapter are connected to the ② guide tube end cap through the pipe thread, and the atomizing nozzle (composed of ④ nozzle and ⑤ flow adjustment knob) is connected to the ③ atomizing nozzle through the pipe thread. The ⑥ bracket is connected with the hinged hole on the ② guide tube end cover by means of hinge support, ⑨ the roller is installed at the end of the ⑥ bracket, ⑦ butt joint is connected with the ② guide tube end cover through the pipe thread Connect with ⑧ rotary joint.

[0017] In the process of spraying, the flow of paint can be controlled according to the viscosity and usage of different paints. When adjusting, turn the flow adjustment knob to change the size of the gap between it and the nozzle to adjust the spray flow and atomization effect.

Embodiment 3

[0018] Embodiment 3 The regulation of hollow conical spray taper

[0019] exist figure 1 Among them, the ① guide tube and ③ atomizing nozzle adapter are connected to the ② guide tube end cap through the pipe thread, and the atomizing nozzle (composed of ④ nozzle and ⑤ flow adjustment knob) is connected to the ③ atomizing nozzle through the pipe thread. The ⑥ bracket is connected with the hinged hole on the ② guide tube end cover by means of hinge support, ⑨ the roller is installed at the end of the ⑥ bracket, ⑦ butt joint is connected with the ② guide tube end cover through the pipe thread Connect with ⑧ rotary joint.

[0020] Adjusting the spraying angle of the nozzle can change the diameter of the area covered by the paint to accommodate pipes of different inner diameters. There is a boss with a diameter of Φ10mm on the top of the flow adjustment knob on the nozzle. Its function is to change the shape of the aerosol sprayed from the nozzle into a hollow cone. The taper of...

Abstract

The invention relates to an inner wall spraying device of a round pipeline. The inner wall spraying device is formed by sequentially connecting a guide pipe, a guide pipe end cover, a roller, a support, an atomizing nozzle (consisting of a spray head and a flow control knob), an atomizing nozzle adapter, a connector and a rotary connector according to a specific installation sequence. The inner wall spraying device is specially designed for spraying an inner wall of the round pipeline, so that the inner wall spraying device is simple in structure, reliable in work, convenient to maintain, low in cost, capable of being completely disassembled, wider in application range, uniform for spraying the paint, large in spraying circular coverage range and capable of meeting the spraying requirement of the pipeline with inner diameter of 100mm to 700mm; moreover, the roller is made of polyurethane and is soft, the inner wall of the to-be-sprayed pipeline is not scratched, and a good protection effect can be achieved.

Description

technical field [0001] The invention relates to a spraying device for the inner wall of a circular-diameter pipeline, in particular to a spraying device which can spray anti-corrosion paint on the inner wall of oil pipelines with different inner diameters for heavy anti-corrosion. Background technique [0002] At present, the types and functions of the existing spraying devices are relatively single, the structure is relatively complicated, the manufacturing cost is high, the spraying thickness is uneven, the atomization effect is poor, and it is easy to cause unnecessary waste of paint, and the scope of use is limited, that is, it cannot be used in relatively large areas. It can adapt to the spraying requirements of pipelines with different inner diameters in a wide range. In addition, the rollers of the existing spraying devices are generally made of metal, which is very easy to scratch the inner wall of the pipeline when it moves inside the pipeline to be sprayed. Therefor...
