Description

Technical Field

[0001] This utility model relates to the technical field of pipeline spraying, and in particular to an electrostatic coating anti-corrosion spraying device for pipelines. Background Technology

[0002] Pipeline corrosion prevention refers to measures taken to slow down or prevent pipelines from being eroded and deteriorated by the chemical and electrochemical effects of internal and external media or by the metabolic activities of microorganisms.

[0003] When applying anti-corrosion coating to pipelines, the pipelines must first be fixed in place before the coating is applied. This process requires fixing and then disassembling multiple pipelines to replace them, which is inefficient. Furthermore, the fixed areas of the pipelines cannot be coated, requiring subsequent touch-ups. Therefore, an improvement is needed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the current electrostatic coating anti-corrosion spraying device for pipelines, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an electrostatic coating anti-corrosion pipe anti-corrosion spraying device, which solves the problem that "when spraying multiple pipes in sequence, it is necessary to fix and then disassemble to replace the pipes, resulting in poor pipe spraying efficiency".

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrostatic coating anti-corrosion spraying device for pipelines, comprising:

[0008] The painting unit includes a base, two conveying components on the top of the base, a motor fixedly mounted on the top of the base, a roller rotatably mounted on the top of the base, a pipe body attached to the top of the roller, a paint box fixedly mounted on the top of the base, a pump input end fixedly connected to one side of the paint box, and an annular nozzle fixedly connected to the pump output end.

[0009] The drying unit includes a hot air blower, which is fixedly installed on the top of the base. The output end of the hot air blower is fixedly connected to an air duct, and the other end of the air duct is fixedly connected to an air cylinder. An air outlet ring hole is opened in the inner circumference of the air cylinder. An air guide plate is fixedly installed on the inner side of the air cylinder and outside the air outlet ring hole. An air concentrator is fixedly installed on one side of the air cylinder.

[0010] As a preferred embodiment of the electrostatic coating anti-corrosion spraying device for pipelines described in this utility model, the base has two side plates fixedly installed on its top. An electric push rod is fixedly installed on one side of each of the two side plates. A limit wheel is rotatably installed on one side of each of the two electric push rods via a connecting plate. The two limit wheels are respectively attached to both sides of the pipeline body.

[0011] In a preferred embodiment of the electrostatic coating anti-corrosion spraying device for pipelines described in this utility model, the conveying assembly includes a strip plate, which is fixedly installed on the top of the base. A transmission roller is rotatably installed inside the strip plate. A gear set is fixedly installed on the outer wall of the transmission roller. A transmission roller is fixedly installed at the end of the gear set away from the transmission roller. The gear set is rotatably installed on one side of the strip plate. Both the transmission roller and the transmission roller are attached to the outer wall of the pipeline body.

[0012] In a preferred embodiment of the electrostatic coating anti-corrosion pipe anti-corrosion spraying device of this utility model, one side of the transmission roller is fixedly installed with the motor output shaft, and pulleys are fixedly installed on the outer walls of both transmission rollers, and a transmission belt is sleeved on the outer walls of both pulleys.

[0013] As a preferred embodiment of the electrostatic coating anti-corrosion pipe anti-corrosion spraying device of this utility model, the gear set is composed of four meshing gears, and all four gears are rotatably mounted on one side of the strip plate.

[0014] As a preferred embodiment of the electrostatic coating anti-corrosion pipe anti-corrosion spraying device of this utility model, the air duct and the annular spray nozzle are both fixedly installed on the top of the base, and the top of the paint box is fixedly connected to a water inlet pipe.

[0015] The beneficial effects of this utility model are:

[0016] 1. Insert the main pipe body between drive roller one and drive roller two. The motor drives the gear set to rotate, and drive roller one and drive roller two rotate in opposite directions, pushing the main pipe body forward. As the main pipe body moves forward, the support roller supports the bottom of the main pipe body and rotates with the main pipe body. When the main pipe body reaches the inner circle of the annular nozzle, the pump body draws the paint from the paint box into the annular nozzle, and then sprays it onto the outer wall of the main pipe body through the annular nozzle. The painting is carried out by moving the main pipe body, without the need to fix the main pipe body repeatedly. At the same time, there is no need to touch up the paint at the fixed position of the main pipe body later.

[0017] 2. When the main body of the pipeline reaches the inner perimeter of the annular nozzle, the pump body draws out the paint from the paint box and sprays it onto the outer wall of the pipeline through the annular nozzle. After the painting is completed, the pipeline continues to move forward. When it reaches the inner perimeter of the air duct, the hot air blown out by the hot air blower enters the air duct. The hot air is guided by the air guide plate and blown in the direction of the pipeline's movement. At the same time, the air concentrator gathers the hot air, so that the hot air has a longer contact time with the paint on the outer wall of the pipeline, and blows the paint to dry it. This can quickly dry the paint and improve the painting efficiency. Attached Figure Description

[0028] Reference Figure 1-4 This utility model provides an electrostatic coating anti-corrosion spraying device for pipelines, comprising:

[0029] The painting unit 100 includes a base 101, two conveying components 102 on the top of the base 101, a motor 103 fixedly installed on the top of the base 101, the motor 103 provides power, a roller 104 is rotatably installed on the top of the base 101, the top of the roller 104 is in contact with the pipe body 105, the roller 104 can stabilize the position of the pipe body 105, a paint box 106 is fixedly installed on the top of the base 101, a pump body 107 input end is fixedly connected to one side of the paint box 106, and an annular nozzle 108 is fixedly connected to the output end of the pump body 107.

[0030] The drying unit 200 includes a hot air blower 201, which provides hot air for drying. The hot air blower 201 is fixedly installed on the top of the base 101. The output end of the hot air blower 201 is fixedly connected to an air duct 202, and the other end of the air duct 202 is fixedly connected to an air duct 203. An air outlet ring hole is opened in the inner circumference of the air duct 203. An air guide plate 204 is fixedly installed on the inner side of the air duct 203 and outside the air outlet ring hole. The air guide plate 204 changes the air direction. An air concentrator 205 is fixedly installed on one side of the air duct 203. The air concentrator 205 makes the hot air blow along the main body of the duct 105.

[0031] The base 101 has two side plates fixedly installed on its top. Each side plate has an electric push rod 110 fixedly installed on one side. Each side of the electric push rod 110 has a limit wheel 111 rotatably installed on one side via a connecting plate. The two limit wheels 111 are respectively attached to both sides of the pipe body 105. The limit wheels 111 fix both sides of the pipe body 105 to prevent the pipe body 105 from tilting during transmission.

[0032] Furthermore, the conveying assembly 102 includes a strip 102a, which is fixedly installed on the top of the base 101. A drive roller 102b is rotatably installed inside the strip 102a. A gear set 102c is fixedly installed on the outer wall of the drive roller 102b. A drive roller 102d is fixedly installed at the end of the gear set 102c away from the drive roller 102b. The gear set 102c is rotatably installed on one side of the strip 102a. The drive roller 102d and the drive roller 102b are both attached to the outer wall of the pipe body 105. The drive roller 102b and the drive roller 102d rotate in opposite directions to output the power for moving the pipe body 105.

[0033] Furthermore, one side of the rotating rod of the transmission roller 102b is fixedly installed to the output shaft of the motor 103. Pulleys are fixedly installed on the outer walls of both transmission rollers 102b, and a transmission belt 109 is sleeved on the outer walls of both pulleys. The transmission belt 109 connects and transmits power, so that one motor 103 can drive both transmission rollers 102b to work simultaneously.

[0034] Furthermore, the gear set 102c is composed of four meshing gears. All four gears are rotatably mounted on one side of the strip 102a. By changing the transmission through the four gears, the rotation directions of the first transmission roller 102b and the second transmission roller 102d are opposite.

[0035] Furthermore, the air duct 203 and the annular nozzle 108 are both fixedly installed on the top of the base 101, and the top of the paint box 106 is fixedly connected to a water inlet pipe, which facilitates filling the paint box 106 with paint.

[0036] During use, the pipe body 105 is first inserted between the first transmission roller 102b and the second transmission roller 102d. The motor 103 drives the gear set 102c to rotate. Under the action of the four gears in the gear set 102c, the first transmission roller 102b and the second transmission roller 102d rotate in opposite directions, pushing the pipe body 105 forward. When the pipe body 105 moves forward, the support roller 104 supports the bottom of the pipe body 105 and rotates as the pipe body 105 moves. When the pipe body 105 reaches the position of the limit wheel 111, the electric push rod 110 first drives the limit wheel 111 to retract. After the pipe body 105 passes through, the electric push rod 110 drives the limit wheel 111 to clamp the pipe body 105 on both sides.

[0037] When the position of the main body of the pipe 105 reaches the inner circumference of the annular nozzle 108, the paint inside the paint box 106 is drawn out by the pump body 107 and sprayed into the annular nozzle 108. Then, the paint is sprayed onto the outer wall of the main body of the pipe 105 through the annular nozzle 108. After the painting is completed, the main body of the pipe 105 continues to move forward. When it reaches the inner circumference of the air duct 203, the hot air blown out by the hot air blower 201 enters the air duct 203. The hot air is guided by the air guide plate 204 and blown in the forward direction of the main body of the pipe 105. At the same time, the air concentrator 205 gathers the hot air, so that the hot air has a longer contact time with the paint on the outer wall of the main body of the pipe 105, and the paint is dried by blowing.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
