Description

Technical Field

[0001] The utility model relates to the technical field of direct buried pipe processing, in particular to a device for coating the outer surface of a heat-insulating direct buried pipe with an anti-corrosion material. Background Art

[0002] Direct buried pipes are widely used in liquid and gas transportation networks, chemical pipeline insulation projects, petroleum, chemical industry, central heating network, central air conditioning ventilation ducts, and municipal engineering. Direct buried pipes are a new technology that has only emerged in recent years. Direct burial means direct burial. However, before laying direct buried pipes, in order to ensure their service life, protective paint is often required on their surface.

[0003] The existing patent (application number 201621003580.0) discloses a multi-station internal and external pipe coating equipment, including a paint spray box, a spray gun and a fire pipe conveying mechanism. The paint spray box is provided with several groups of clamping end heads for clamping at both ends of the fire pipe and driving the fire pipe to rotate. The spray gun is arranged in the paint spray box on the upper and lower sides of the fire pipe, and is used to spray paint on the upper and lower sides of the fire pipe at the same time.

[0004] The above patent expands the spray range of the paint by setting two spray guns at the top and bottom, and rotates the fire hose during the painting process, thereby ensuring that the surface of the fire hose can be evenly sprayed with paint, thereby improving the painting effect. However, after the pipe is sprayed, the paint still needs a certain amount of time to dry. At this time, if the pipe is touched, it will affect the spraying effect. Waiting for it to dry is a waste of time, which affects the spraying efficiency of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a device for coating the outer surface of a heat-insulating direct-buried pipe with an anti-corrosion material, which can effectively solve the problem that the pipe is difficult to dry quickly after spraying.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for coating the outside of a thermally insulated directly buried pipe with an anti-corrosion material comprises a base, a material receiving pool is installed at the front upper end of the base, clamping devices are installed at the upper left and upper right ends of the base, a fixed box is installed at the rear upper end of the base, a drying device is installed at the middle upper end of the fixed box, fixed frames are installed at the upper left and upper right ends of the fixed box, a spraying device is installed at the front ends of the two fixed frames, and a paint box is installed at the upper right end of the base.

[0008] Preferably, the drying device includes a heater, a heating tube is installed at the lower end of the heater, the heater is installed in the middle of the upper end of the fixed box, an air outlet is opened in the middle of the front end of the fixed box, a mounting port is installed in the middle of the rear end of the fixed box, and two fans are installed on the inner wall below the mounting port. The heater drives the heating tube to heat the air inside the fixed box, and after the air is heated, it is blown through the two fans on the mounting port, so that the hot air is blown from the air outlet to the outer surface of the direct buried pipe, so that the paint sprayed on it can be dried quickly.

[0009] Preferably, the spraying device includes a connection seat and a pump body, a group of nozzles are installed at the lower end of the connection seat, a connecting pipe is installed at the right end of the connection seat and the front end of the pump body, the pump body is installed at the right end of the paint box, and the connection seat is installed at the front end of two fixing frames. The anti-corrosion paint in the paint box is extracted by the pump body and transported to the nozzle at the lower end of the connection seat through the connecting pipe, and the nozzle then sprays the paint on the outer surface of the direct buried pipe.

[0010] Preferably, the clamping device includes a support seat, a hydraulic cylinder is installed at the lower left end of the support seat, a slider is installed at the lower end of the support seat, a motor is installed at the upper end of the support seat, a fixed cylinder is installed at the right end of the motor, and the support seat is installed at the upper left end of the base through the slider. The support seat is pushed by the hydraulic cylinder, and the support seat is then slid and adjusted on the base through the slider at the lower end, so that the direct buried pipe is clamped between the two fixed cylinders, and the fixed cylinder is driven by the motor to rotate, so that the outside of the direct buried pipe also rotates, so that the outer surface of the direct buried pipe is more uniform during spraying.

[0011] Preferably, the two clamping devices are symmetrically distributed left and right with the material receiving pool as the center.

[0012] Preferably, the air outlet and the installation port are located front to back in correspondence with each other.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When it is necessary to spray anti-corrosion material on the outer surface of the direct-buried pipe, first place the direct-buried pipe in the fixed cylinder on the clamping device. At this time, the support seat is pushed by the hydraulic cylinder, and the support seat is then slid and adjusted on the base through the slider at the lower end, so that the direct-buried pipe is clamped between the two fixed cylinders. At this time, the anti-corrosion paint in the paint box is extracted by the pump body on the spraying device and transported to the nozzle at the lower end of the connecting seat through the connecting pipe. The nozzle then sprays the paint on the outer surface of the direct-buried pipe. At the same time, the fixed cylinder is driven by the motor to rotate, so that the outside of the direct-buried pipe also rotates, so that the outer surface of the direct-buried pipe is more uniform during spraying.

[0015] 2. After the outer surface of the direct-buried pipe is sprayed, the direct-buried pipe continues to rotate through the motor. At this time, the heater on the drying device drives the heating pipe to heat the air inside the fixed box. After the air is heated, it is blown through the two fans on the installation port, and then the hot air is blown from the air outlet to the outer surface of the direct-buried pipe, so that the paint sprayed on it can be quickly dried, thereby improving the spraying efficiency of the device.
