Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and more specifically to a steel pipe anti-corrosion coating device. Background Technology

[0002] The steel pipe anti-corrosion coating device includes a frame, on which a spray head connected to a telescopic cylinder is mounted. The frame also has a raw material silo, which holds the anti-corrosion coating. The anti-corrosion coating solidifies on the wall of the steel pipe to form an anti-corrosion layer. The raw material silo is connected to the spray head via a conveying pipe, in which a conveying pump is installed. Multiple sets of rollers, arranged from left to right, are also mounted on the frame. Each set of rollers includes a front roller and a rear roller, and the rollers are connected to a roller motor. In use, the steel pipe is placed on the multiple sets of rollers, and the spray head is positioned on the side of the steel pipe wall. The anti-corrosion coating sprayed by the spray head solidifies on the steel pipe wall to form an anti-corrosion layer. As the telescopic components extend and retract, different parts of the steel pipe wall can be sprayed, resulting in an anti-corrosion layer forming inside the steel pipe.

[0003] In existing technologies, the anti-corrosion coating devices for steel pipes lack protective devices, which means that the anti-corrosion coating sprayed on the steel pipes will spread into the surrounding environment, endangering the health of operators and polluting the surrounding environment. Summary of the Invention

[0005] The technical solution of this utility model is implemented as follows: a closed-type steel pipe anti-corrosion coating device includes a device frame, on which a spray head connected by a telescopic cylinder is installed. The device frame also has a raw material silo, which is a component for holding anti-corrosion coating. The anti-corrosion coating solidifies on the wall of the steel pipe to form an anti-corrosion layer. The raw material silo is connected to the spray head via a conveying pipe, and a conveying pump is installed in the middle of the pipe. Multiple sets of rollers from left to right are also installed on the device frame, each set including a front roller and a rear roller, and the rollers are connected to a roller motor. Its characteristic is that it also includes a box body, which includes a lower main box and an upper box cover. The box body has an internal cavity, and the side of the box body has perforations. The telescopic cylinder extends into the cavity through the perforations, and the multiple sets of rollers are installed inside the cavity.

[0006] Furthermore, the telescopic cylinder includes an inner telescopic cylinder installed inside the steel pipe to be coated and an outer telescopic cylinder installed outside the steel pipe to be coated. The nozzle connected to the inner telescopic cylinder is the inner nozzle, which can spray anti-corrosion coating onto the inside of the steel pipe. The nozzle connected to the outer telescopic cylinder is the outer nozzle, which can spray anti-corrosion coating onto the outside of the steel pipe.

[0007] Furthermore, the enclosure is mounted on the device frame with vibration damping pads, and a vibration device is also installed on the enclosure.

[0008] Furthermore, a control device is also installed on the side of the box, and the telescopic cylinder is connected to the control device, as is the vibration device.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] like Figure 1 , 2As shown, a closed-type steel pipe anti-corrosion coating device includes a frame 1, a spray head 3 connected to a telescopic cylinder 2 mounted on the frame, a raw material silo 4 on the frame, the raw material silo being a component for holding anti-corrosion coating, the anti-corrosion coating solidifying on the wall of the steel pipe to form an anti-corrosion layer, the raw material silo being connected to the spray head via a conveying pipe 41, a conveying pump 42 being installed in the middle of the pipe, and multiple sets of rollers 5 from left to right mounted on the frame, each set of rollers including a front roller 51 and a rear roller 52, the rollers being connected to a roller motor 53; its characteristic is that it also includes a box 6, the box including a lower main box 61 and an upper box cover 62, the box having an internal box cavity 63, the side of the box having a perforation 64, the telescopic cylinder extending into the box cavity through the perforation, and the multiple sets of rollers being installed inside the box cavity.

[0015] Because of the above-mentioned technical solution, when the anti-corrosion coating is sprayed onto the steel pipe 10, the particles formed by the anti-corrosion coating are inside the box and will not overflow, thus achieving the purpose of this utility model.

[0016] Furthermore, the telescopic cylinder includes an inner telescopic cylinder 21 installed inside the steel pipe to be coated and an outer telescopic cylinder 22 installed outside the steel pipe to be coated. The nozzle connected to the inner telescopic cylinder is an inner nozzle 31, which can spray anti-corrosion coating onto the inside of the steel pipe.
