Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a device for controlling the temperature between welding layers of a grinding roller surfacing weld. Background Art

[0002] In-line surfacing welding of grinding rollers is a commonly used process to improve the hardness and wear resistance of grinding rollers. This process is an open arc welding process with advantages such as high welding efficiency and good longitudinal growth of metallographic structure.

[0003] However, during high-speed surfacing, the rollers are prone to overheating. Since welding stress cannot be released in time, this can lead to severe cracks, reducing the roller's service life and safety. Currently, manual spray cooling is often used to cool the rollers. However, manual temperature control is not stable enough to effectively prevent defects caused by roller overheating.

[0004] Therefore, a device for controlling the temperature between welding layers of grinding roller surfacing is proposed. Utility Model Content

[0025] like Figures 1 to 4 As shown, a device for controlling the temperature between welding layers of a grinding roller surfacing is provided, comprising a base box 1, a water collecting tank 2 being fixedly connected to the top surface of the base box 1, the interior of the water collecting tank 2 containing cooling water, a spray assembly 3 for spraying cooling water onto the surface of the grinding roller being installed on the top of the water collecting tank 2, baffles 5 being fixedly connected to the top and back surfaces of the base box 1, an impurity filtering assembly 4 for filtering the cooling water being installed on the surface of the baffle 5, a reflux assembly 6 for conveying cooling water into the interior of the water collecting tank 2 being provided on the front surface of the base box 1, a cooling assembly 7 being provided on the surface of the water collecting tank 2, a non-contact infrared temperature sensor 8 being fixedly installed on the top of the water collecting tank 2, and a DCS controller 9 being fixedly installed on the right side of the water collecting tank 2. More specifically, the grinding roller surfacing station is set between two baffles 5. The temperature of the weld during the welding process is detected in real time by a non-contact infrared temperature sensor 8, and the data is transmitted back to the DCS controller 9. When the temperature is detected to be higher than the set value, the DCS controller 9 controls the operation of the spray component 3 to extract the cooling water in the water collecting tank 2 and perform water mist cooling on the grinding roller, thereby controlling the interlayer temperature. The spray water will fall on the top of the bottom box 1, and the cooling water can be diverted to the inside of the bottom box 1 through the impurity filtering component 4, and the impurities mixed in the cooling water can be filtered. The filtered cooling water is then introduced into the water collecting tank 2 through the reflux component 6, and the cooling water returning to the water collecting tank 2 can be cooled by the cooling component 7, thereby recycling the cooling water.

[0026] The spray assembly 3 includes a first water pump 301, which is fixedly mounted on the top of the water collection tank 2. The water inlet of the first water pump 301 is fixedly connected to a water pumping pipe 304, and the water outlet of the first water pump 301 is fixedly connected to an outlet pipe 302. The end of the outlet pipe 302 is fixedly connected to a spray nozzle 303. It should be noted that the cooling water inside the water collection tank 2 is pumped out by the first water pump 301, transported through the outlet pipe 302, and finally sprayed onto the grinding roller through the spray nozzle 303 to cool the grinding roller.

[0027] The impurity filtering assembly 4 includes a filter screen 401, and the filter screen 401 is embedded in the top surface of the bottom box 1. A first motor 406 is fixedly installed inside the front baffle 5. The output end of the first motor 406 is fixedly connected to a threaded column 402. The surface of the threaded column 402 is threadedly connected to a mounting rod 403. A slide groove 404 is opened through the surface of the front baffle 5, and the inner wall of the slide groove 404 is slidably connected to the surface of the mounting rod 403. A cleaning brush 405 is fixedly connected to the bottom surface of the mounting rod 403, and the cleaning brush 405 is slidably connected to the filter screen 401. Collection tanks 407 are fixedly connected to the left and right sides of the bottom box 1. More specifically, the cooling water sprayed onto the surface of the grinding roller by the spray assembly 3 will flow to the top of the bottom box 1, and the impurities on the surface of the grinding roller will be filtered through the filter 401. The cooling water will pass through the filter 401 and flow back to the interior of the bottom box 1. The first motor 406 will drive the threaded column 402 to rotate, and the mounting rod 403 will be driven to slide along the inner wall of the slide 404 under the action of the thread, thereby controlling the movement of the cleaning brush 405. The cleaning brush 405 is used to clean the surface of the filter 401 to prevent the filter 401 from being blocked, and the impurities can be pushed to the internal storage of the collection tank 407.

[0028] The reflux assembly 6 includes a second water pump 601, which is fixedly mounted on the front of the bottom box 1. The water inlet of the second water pump 601 is connected to the interior of the bottom box 1, and the water outlet of the second water pump 601 is fixedly connected to a water pipe 602, which is also fixedly connected to the water collection tank 2. It should be noted that the operation of the second water pump 601 can pump out the filtered cooling water from the interior of the bottom box 1 and transport it into the interior of the water collection tank 2 through the water pipe 602, thereby achieving the reuse of the cooling water.

[0029] Cooling assembly 7 includes a semiconductor refrigeration chip 701, which is fixedly mounted on the back of water collection tank 2. A cooling fin 703 is fixedly connected to the cold end of semiconductor refrigeration chip 701, which contacts the cooling water. Heat sink fins 702 are fixedly connected to the hot end of semiconductor refrigeration chip 701. More specifically, as semiconductor refrigeration chip 701 operates, its cold end cools the water, while the cooling fins 703 contact the cooling water, thereby cooling the cooling water. Heat sink fins 702 accelerate heat dissipation at the hot end of semiconductor refrigeration chip 701.

[0030] The cooling assembly 7 also includes a partition 704, and the partition 704 is fixedly connected to the bottom of the inner wall of the water collecting tank 2, and there is a gap between the top of the partition 704 and the top surface of the inner wall of the water collecting tank 2. A second motor 705 is fixedly installed on the left side of the water collecting tank 2, and the output end of the second motor 705 is fixedly connected to a rotating shaft 706, and the surface of the rotating shaft 706 is fixedly connected to a stirring blade 707. It should be noted that by providing the partition 704, after the cooling water enters the water collecting tank 2, it needs to climb over the partition 704 before it can flow to the right, thereby increasing the contact time between the cooling water and the cooling plate 703, improving the cooling effect on the cooling water, and at the same time, the second motor 705 drives the rotating shaft 706 and the stirring blade 707 to rotate, stirring the cooling water, so that the cooling water is cooled more evenly.

[0031] In summary: the grinding roller surfacing station is set between two baffles 5, and the temperature of the weld during the welding process is detected in real time by a non-contact infrared temperature sensor 8, and the data is transmitted back to the DCS controller 9. When the temperature is detected to be higher than the set value, the DCS controller 9 controls the spray component 3 to operate, extracts the cooling water in the water collecting tank 2, and performs water mist cooling on the grinding roller, thereby controlling the interlayer temperature. The spray water will fall on the top of the bottom box 1, and the cooling water can be diverted to the inside of the bottom box 1 through the impurity filtering component 4, and the impurities mixed in the cooling water are filtered. Then, the filtered cooling water is introduced into the water collecting tank 2 through the reflux component 6, and the cooling water returning to the water collecting tank 2 can be cooled by the cooling component 7, thereby recycling the cooling water. In use, it is easy to effectively cool the grinding roller surfacing process, can accurately detect and control the interlayer temperature, thereby avoiding defects caused by overheating, improving the quality of surfacing, reasonably releasing stress, and preventing the occurrence of malignant cracks. In addition, the spray water can be recycled, effectively saving cooling water.
