Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and specifically to a PPR pipe cooling device. Background Art

[0002] PPR is the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipe. It adopts the hot melt connection method and has special welding and cutting tools. It has high plasticity. With an additional insulation layer, its insulation performance is better. The pipe wall is also very smooth and does not include internal and external thread joints. It is generally used for embedded walls or deep well buried pipes. The PPR pipe has a moderate price, stable performance, heat resistance and insulation, corrosion resistance, a smooth inner wall without scaling, a safe and reliable pipe system, and no leakage. Its service life can reach 50 years.

[0003] When processing the butt joint of PPR pipes, it is necessary to melt the end of the pipe by hot melt and then butt it with the sleeve. In order to ensure that the pipe and the sleeve can melt, a relatively high hot melt temperature is required. However, after the pipe butt joint, it is generally cooled and solidified by natural heat dissipation or cold water spraying. Most general spraying devices are a spray pipe arranged above the operating table. It not only forms an obstruction above during operation, but also has no obstruction between the water flow and the operator when spraying and cooling the butt joint, which easily causes the water flow to splash onto the operator.

[0035] Working principle: When flipping the flow blocking mechanism, start the flipping motor 106. The flipping motor 106 rotates forward. The flipping motor 106 drives the driving sprocket 108 to rotate through the worm and gear reducer 105. The driving sprocket 108 drives the driven sprocket 109 through the synchronous belt 110 to make the transmission shaft 107 rotate. The transmission shaft 107 drives the curved rack 209 through the flipping gear 111 to make the cover plate 207 and the main frame 201 flip forward. When the flipping motor 106 rotates reversely, the flipping motor 106 drives the driving sprocket 108 to rotate reversely through the worm and gear reducer 105. The driving sprocket 108 drives the driven sprocket 109 through the synchronous belt 110 to make the transmission shaft 107 rotate reversely. The transmission shaft 107 drives the curved rack 209 through the flipping gear 111 to make the cover plate 207 and the main frame 201 flip backward; When cooling with cold water, first inject cold water into the interior of the water tank 101, then close the drain solenoid valve 304 and the cold air solenoid valve 406, open the cold water solenoid valve 306, and then start the water pump 301. The water pump 301 pumps cold water. The cold water first enters the filter box 307 through the water guide slit 311, passes through the sponge block 309 for filtration, then passes through the filter net 308 to reach the interior of the filter box 307, then enters the water pump 301 through the water inlet pipe 302, is then pumped into the first three-way seat 303, and then enters the interior of the main frame 201 through the water guide hose 305 and the cold water solenoid valve 306, and then sprays out through the seepage slit, thereby cooling the pipe. When draining water, close the open cold water solenoid valve 306 and open the drain solenoid valve 304 to drain the water flow entering the first three-way seat 303; When cooling with cold air, close the cold water solenoid valve 306 and start the air pump 401. The air pump 401 pumps air. The air flow first passes through the air filter element 403 for filtration and then enters the air pump 401, and then is pumped into the second three-way seat 402. The air gradually enters the slow pressure tube tank 404 for internal storage and pressurization. Then open the cold air solenoid valve 406, and the pressurized air enters the interior of the main frame 201 through the air guide hose 405 and the cold air solenoid valve 406, and then sprays out through the seepage slit, thereby cooling the pipe; When adjusting the size of the water flow or air flow, turn the handwheel 212. The handwheel 212 drives the threaded column 211 to rotate. When the threaded column 211 rotates, it pushes the threaded cylinder 215, causing the two adjusting blocks 214 to move towards the middle or both sides along the support column 206. When the adjusting block 214 moves towards the middle, it will squeeze the isolation sheet 205 to close through the inner pressure plate 203, and the elastic rubber sheet 204 is deformed by pressure, and the seepage slit decreases, and the flow rate of the water flow or air flow when spraying out decreases, and the pressure increases. When the adjusting block 214 moves towards both sides, it will pull the isolation sheet 205 to stretch through the inner pressure plate 203, and the elastic rubber sheet 204 is deformed by tension, and the seepage slit increases, and the flow rate of the water flow or air flow when spraying out increases, and the pressure decreases; In use, first start the flipping motor 106 to make the flipping baffle mechanism flip downward to avoid blocking the welding. If it is necessary to weld a pipe and a pipe sleeve, turn the threaded push rod 604 to adjust the position of the blocking head 605 to ensure that the blocking head 605 is located at the middle position above the flipping baffle mechanism. Then place the pipe after hot melt butt joint on the surface of the pipe support seat 501, and press one side of the pipe sleeve against the blocking head 605 so that the interface is located above the flipping baffle mechanism. Then start the flipping motor 106 to make the flipping baffle mechanism flip upward and block the pipe in an inverted manner. Then perform cold water cooling or cold air cooling. If welding pipes to each other, move the threaded push rod 604 to disengage the hook 603 from the inside of the card slot 502 for disassembly. Then place the two pipes after hot melt butt joint on the surfaces of the two pipe support seats 501 so that the interface is located above the flipping baffle mechanism. Then start the flipping motor 106 to make the flipping baffle mechanism flip upward and block the pipes in an inverted manner. Then perform cold water cooling or cold air cooling, thereby avoiding water splashing and also avoiding the blocking operation above before cooling.
