[0023] The overall effect of Embodiment 1 is as follows: the temperature of the weld is detected by a second temperature sensor 207 installed on the outer wall of the cooling nozzle 206, and the temperature inside the water storage tank 101 is monitored by a first temperature sensor 107. By combining the temperatures monitored by the two sensors, the temperature of the coolant is precisely controlled by the cooler 106. The flow rate and water temperature are adjusted according to the real-time temperature of the weld to ensure stable cooling effect and improve the quality of welded pipe processing. A circulating pump 204 is fixedly installed on one side of the water storage tank 101, and the inlet of the circulating pump 204 is inserted into the water storage tank 101. Inside the 1, the circulating pump 204 draws coolant from the water storage tank 101. The drawn coolant flows through the circulating water pipe 205 and is sprayed onto the weld seam of the welded pipe by the cooling nozzle 206 to cool the weld seam. The cooling nozzle 206 increases the contact area between the cooling water and the weld seam through high-pressure atomization spraying, which facilitates faster cooling of the weld seam and improves processing efficiency. The sprayed coolant flows through the through hole opened inside the welding station 104 to the filter plate 202. After being filtered twice by the filter plate 202 and the filter box 201, it is re-accumulated inside the water storage tank 101 to realize the recycling of coolant.

[0024] Example 2: Figures 1-4As shown, one end of the water storage tank 101 is connected to an inlet pipe 102 and an outlet pipe 103. The inlet pipe 102 is positioned above the outlet pipe 103. A welding station 104 is provided on the inner wall of the water storage tank 101. A high-temperature resistant pad 105 is fixedly installed on the top of the welding station 104. A sliding groove 108 is provided on the top of the water storage tank 101. A set of mounting grooves 109 are provided on the inner wall of the water storage tank 101, and the set of mounting grooves 109 are arranged opposite to each other. Both sides of the filter box 201 are fixedly connected to mounting... Block 203, the outer wall of the circulating water pipe 205 is fitted with a fixing ring 209, and the bottom of the fixing ring 209 is fixedly connected with a sliding support plate 208; a set of mounting blocks 203 are respectively set inside a set of mounting grooves 109, the filter box 201 is set at the bottom of the welding station 104, and the sliding support plate 208 is slidably set inside the sliding groove 108; the circulating pump 204 is fixedly installed on one side of the water storage tank 101, and the water inlet end of the circulating pump 204 is inserted into the inside of the water storage tank 101.

[0025] The overall effect of Embodiment 2 is as follows: by installing a welding station 104 on the inner wall of the water storage tank 101, it is convenient to place the welding pipe on the top of the welding station 104 for welding. A high-temperature resistant pad 105 is installed on the top of the welding station 104 to protect the welding station 104 and prevent welding debris from splashing onto the welding station 104 and sticking, which would affect later use; an inlet pipe 102 and an outlet pipe 103 are fixedly connected at one end of the water storage tank 101 to connect with external pipelines to complete the introduction and discharge of coolant; and a circulating pump 204 is used to draw coolant from inside the water storage tank 101. The extracted coolant flows through the circulating water pipe 205 and is sprayed onto the weld seam of the welded pipe by the cooling nozzle 206 to cool the weld seam. After spraying, the coolant flows through the through hole in the welding station 104 to the filter plate 202. After being filtered twice by the filter plate 202 and the filter box 201, the coolant is re-accumulated inside the water storage tank 101 to realize the recycling of the coolant. At the same time, the end of the circulating water pipe 205 is fixed by the fixing ring 209, and the sliding support plate 208 is slidably connected to the slide groove 108 to adjust the spray position of the cooling nozzle 206 according to the weld seam position.

[0026] Working principle: When using this device, firstly, a welding station 104 is installed on the inner wall of the water storage tank 101, which facilitates the placement of the welding pipe on top of the welding station 104 for welding. A high-temperature resistant pad 105 is installed on top of the welding station 104 to protect it and prevent welding debris from splashing onto the welding station 104 and sticking together, which would affect later use. An inlet pipe 102 and an outlet pipe 103 are fixedly connected at one end of the water storage tank 101 to connect with external pipelines to complete the discharge and release of coolant.

[0027] Secondly, by fixing a circulation pump 204 to one side of the water storage tank 101 and inserting the water inlet of the circulation pump 204 into the inside of the water storage tank 101, the circulation pump 204 draws the coolant inside the water storage tank 101. The drawn coolant flows through the circulation water pipe 205 and is sprayed onto the weld seam of the welded pipe by the cooling nozzle 206 to cool the weld seam. The cooling nozzle 206 increases the contact area between the cooling water and the weld seam by high-pressure atomization spraying, which facilitates faster cooling of the weld seam and improves processing efficiency.

[0028] Then, an installation groove 109 is opened inside the opposite side of the water storage tank 101. The installation blocks 203 installed on both sides of the filter box 201 are respectively placed inside a set of installation grooves 109 to install and fix the filter box 201. The filter plate 202 is installed inside the filter box 201. The diameter of the filter hole of the filter plate 202 is larger than the diameter of the filter hole of the filter box 201. When cooling the weld seam of the weld pipe set on the top of the welding station 104, the sprayed coolant flows from the through hole opened inside the welding station 104 to the filter plate 202. After being filtered twice by the filter plate 202 and the filter box 201, the coolant is re-accumulated inside the water storage tank 101 to realize the recycling of the coolant. At the same time, the end of the circulating water pipe 205 is fixed by the fixing ring 209, and the sliding support plate 208 is slidably connected to the slide groove 108. The spray position of the cooling nozzle 206 is adjusted according to the weld seam position.

[0029] Finally, the temperature of the weld is detected by the second temperature sensor 207 installed on the outer wall of the cooling nozzle 206, and the temperature inside the water storage tank 101 is monitored by the first temperature sensor 107. Combining the temperatures monitored by the two sensors, the temperature of the coolant is precisely controlled by the cooler 106. The flow rate and water temperature are adjusted according to the real-time temperature of the weld to ensure stable cooling effect and improve the quality of welded pipe processing.

[0030] The wiring diagrams of the cooler 106, the first temperature sensor 107, the circulating pump 204, and the second temperature sensor 207 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the cooler 106, the first temperature sensor 107, the circulating pump 204, and the second temperature sensor 207 will not be explained in detail.
