Technical Field
[0001] The utility model relates to the field of pipeline processing, in particular to a cooling device for pipeline processing. Background Art
[0002] Cast iron pipes are pipes cast by cast iron. Cast iron pipes are used for water supply, drainage and gas transmission pipelines. They include cast iron straight pipes and fittings. They have low labor intensity. According to different casting methods, they are divided into continuous cast iron pipes and centrifugal cast iron pipes. Centrifugal cast iron pipes are further divided into sand molds and metal molds. According to different materials, they are divided into gray cast iron pipes and ductile iron pipes. According to different interface forms, they are divided into flexible interfaces, flange interfaces, self-anchoring interfaces, rigid interfaces, etc.
[0003] After the existing cast iron pipes are processed, their surface temperature is high and they need to be cooled. Most methods nowadays are to directly put the pipes into cold water for cooling, or to use cold air to continuously blow the pipe surface for cooling. However, whether air cooling or water cooling is performed, corresponding devices are required, and the back and forth adjustment operation is troublesome and takes up more space. After the pipes are water-cooled, the coolant is mostly discharged directly and replaced with new coolant, and it is impossible to filter and collect for secondary use, which is not economical and environmentally friendly.

The used coolant will fall into the water collecting tank 2 through the workbench 1, and the set return water pump 6 can extract the coolant from the inside of the water collecting tank 2, and then return it to the inside of the cooling box 4 for secondary use.
[0031] Furthermore, the middle of the workbench 1 is a hollow structure (to facilitate the coolant to fall through the workbench 1 ), and a driving roller 11 and a fixed roller 12 are symmetrically installed in the middle of the inner cavity of the workbench 1 , and a rotating motor 13 is installed at one end of the driving roller 11 .
[0032] The pipe that needs to be cooled is placed between the driving roller 11 and the fixed roller 12. At this time, the pipe will not roll to both sides. When the pipe needs to be turned over, the rotating motor 13 can be used to drive the driving roller 11 to rotate.

[0038] The output end of the water pump 5 is connected to one side of the first three-way ball valve 81 through a positioning tube 83, so that the extracted coolant is transported to the inside of the first three-way ball valve 81 through the positioning tube 83, and then transported to the discharge component 9 through the delivery tube 82. The air pump 7 is connected to one side of the first three-way ball valve 81 using a connecting hose 84, so that the extracted cool air is transported to the inside of the first three-way ball valve 81 through the connecting hose 84, and finally transported to the discharge component 9 through the delivery tube 82.
[0039] Furthermore, a solenoid valve 841 is installed at one end of the positioning tube 83 and the connecting hose 84 .
[0040] When the positioning tube 83 transports coolant, the solenoid valve 841 at one end of the positioning tube 83 is in an open state, while the solenoid valve 841 at one end of the connecting hose 84 is in a closed state, preventing the coolant from entering the vacuum pump 7 through the connecting hose 84. When the connecting hose 84 transports cold air, the solenoid valve 841 at one end of the positioning tube 83 is in a closed state, while the solenoid valve 841 on the connecting hose 84 is in an open state, preventing cold air from entering the water pump 5 through the positioning tube 83.
[0041] Furthermore, the discharge assembly 9 includes a second three-way valve 91 and guide pipes 92 symmetrically installed on both sides of the second three-way valve 91 , a base 93 is installed at intervals at the bottom of the guide pipe 92 , and a nozzle 94 is installed at intervals on one side of the guide pipe 92 .

The bottom of the guide pipe 92 is fixed to both sides of the upper end of the workbench 1 through the base 93, so that the guide pipe 92 can use the nozzle 94 to spray coolant or cold air from both sides of the pipe to accelerate the cooling effect.
[0043] The use process of the utility model is as follows: when in use, the pipe that needs to be cooled is placed between the driving roller 11 and the fixed roller 12. If air blowing is needed to cool down, the solenoid valve 841 on the connecting hose 84 can be opened, and then the solenoid valve 841 on the positioning tube 83 can be closed, and then the vacuum pump 7 is started to extract cold air. The extracted cold air is then transported to the inside of the first three-way ball valve 81 through the connecting hose 84, and then transported to the inside of the second three-way valve 91 through the delivery pipe 82, and finally diverted to the inside of the two guide pipes 92 by the second three-way valve 91. At this time, the guide pipe 92 can use the nozzle 94 to spray cold air from both sides of the pipe to cool down the pipe. If water is needed, When it is cold, the solenoid valve 841 on the positioning tube 83 can be opened, and then the solenoid valve 841 on the connecting hose 84 can be closed, and then the water pump 5 can be started to extract the coolant inside the cooling box 4. The extracted coolant is transported to the inside of the first three-way ball valve 81 through the positioning tube 83, and then transported to the inside of the second three-way valve 91 by the delivery pipe 82, and finally diverted to the inside of the two guide tubes 92 by the second three-way valve 91. At this time, the guide tube 92 can use the nozzle 94 to spray coolant from both sides of the pipeline to cool the pipeline. The used coolant will fall into the water collecting tank 2 through the workbench 1, and the set return water pump 6 can extract the coolant from the inside of the water collecting tank 2 for recycling.
