Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying of economizer pipelines, in particular to a paint spraying device. Background Art

[0002] In the process of coal combustion, economizers are widely used as an important energy-saving device. Economizers recover heat from flue gas, improve the thermal efficiency of boilers, and reduce energy consumption. However, during the operation of economizers, since the wind contains a lot of smoke particles, it will wear the pipes, and regular anti-wear treatment is required to avoid the occurrence of "pipe bursting".

[0003] In the existing production process, the distance between economizer pipes is small, the upper and lower layers are staggered, and manual entry for spraying is impossible. In actual processing, "point-to-point" spraying is mostly adopted, which requires spraying one by one. Not only is the spraying discontinuous, wasting manpower and material resources, but the spraying effect is poor, which seriously affects the later use.

[0004] Chinese patent application CN203598974U was published on May 21, 2014. A slurry spray gun is disclosed, specifically a small space paint spray gun for the surface protection construction of power station boiler heat exchanger (economizer, reheater) tubes. From the front end to the rear end of the spray gun, it is composed of: nozzle, slurry pipe, external air pipe, back seat; the slurry pipe and the external air pipe are mutually sleeved and connected with the nozzle to form a nozzle structure; the slurry pipe and the external air pipe are mutually sleeved and cooperate with the back seat to form a gas-liquid split motion structure; the slurry pipe is divided into an inner slurry pipe and an outer slurry pipe. However, it obviously has the problem of discontinuous spraying and low efficiency during use. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a paint spraying device. Through the setting of a traction rope fixing point, a traction rope and an adapter, the spray head can be directly extended between the economizer pipes, and the moving spraying can be carried out between the pipes, which greatly improves the spraying efficiency and can spray one layer of the pipe at a time, thereby improving the spraying effect. Through the coordinated use of a hemispherical notch, a traction rope and a pulling rod, the moving direction of the spray head can be controlled by the traction rope, which greatly improves the accuracy of spraying and solves the problem of discontinuous spraying.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] The paint spraying device includes a spray head, which is connected to a connecting pipe through an adapter. A spherical traveling head is provided on the spray head, a first-level spraying port is provided above the spray head, the first-level spraying port is connected to a high-pressure feed pipeline, a control wheel is provided on the connecting pipe, and the spherical traveling head is connected to the control wheel through a traction rope.

[0008] The connecting pipe is a bendable pipe used to push the spray head.

[0009] The spherical traveling head is located at a side away from the adapter, and a traction rope fixing point and a hemispherical notch are arranged on the spherical traveling head, and the traction rope fixing point is located below the hemispherical notch.

[0010] The setting of the hemispherical notch makes it easier for the pulling hook to hang the traction rope.

[0011] The adapter is provided with a conversion wheel, the fixing point of the traction rope is connected to the conversion wheel through a hemispherical notch, and the conversion wheel is connected to the control rotating wheel through the traction rope.

[0012] The traction rope fixing point, the hemispherical notch and the conversion wheel are connected by the traction rope.

[0013] The spray head is provided with a secondary spray port, which is connected to a high-pressure feed pipe, and a coating connecting pipe is connected to the high-pressure feed pipe.

[0014] A pulling rod is arranged on the side wall of the connecting pipe, and an auxiliary lighting lamp and a pulling hook are arranged on the pulling rod.

[0015] The pulling rod can be removed from the connecting pipe.

[0016] The control wheel is provided with a handle, and the spray head is located below the economizer pipe when working. The handle is used to control the retraction and extension of the traction rope.

[0017] The working principle of the utility model is:

[0018] Insert the spray head between the two economizer pipes. After reaching the pipe layer to be sprayed, retract the traction rope by controlling the rotating wheel, the spherical traveling head tilts up, and pushes the spray head through the connecting pipe to make the spray head move under the pipe layer to be sprayed; continue to push the connecting pipe to make the spray head reach the other end of the pipe layer to be sprayed, remove the pulling rod, and hook out the traction rope by passing the pulling hook through the hemispherical notch. Then, the spray head can be controlled through the connecting pipe and the traction rope for spraying. The setting of the hemispherical notch makes it easier for the pulling hook to hook the traction rope. The turning handle is used to control the retraction and release of the traction rope.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] By adopting the paint spraying device of the utility model, through the setting of the traction rope fixing point, the traction rope and the adapter, the spray head can be directly extended between the economizer pipes, and the moving spraying can be carried out between the pipes, which greatly improves the spraying efficiency, and can spray one layer of the pipe at a time, thereby improving the spraying effect; through the coordinated use of the hemispherical notch, the traction rope and the pulling rod, the moving direction of the spray head can be controlled by the traction rope, which greatly improves the accuracy of spraying and solves the problem of discontinuous spraying; through the coordinated use of the primary spray port and the secondary spray port, the spraying area and the spraying depth are greatly improved.
