[0002] Finishing rolling is the last step in the steel rolling process. Its purpose is to perform more refined processing on the steel based on rough rolling to control its dimensional accuracy, surface quality, mechanical properties, etc.

[0003] Currently, in the process of finishing rolling of steel, in order to improve the production site environment and control emissions, bag dust collectors are used to effectively absorb the smoke generated by rolling. However, the temperature of the hot rolling process is as high as 800°C. If the bag dust collector is turned on for a long time, the high-temperature air flow mixed with smoke and dust enters the dust collector from the pipeline, and the temperature inside the dust collector will gradually increase. When it exceeds a certain temperature, the dust collector will be damaged, thereby affecting the dust removal effect and even causing the dust collector to catch fire, making the bag dust collector unsuitable for use in finishing rolling, which poses certain risks. Utility Model Content

[0022] The utility model provides Figure 1-3 The sewage circulation dust removal and cooling device shown includes:

The smoke is passed into an air inlet joint 5 of the cooling component and dispersed into a plurality of connecting pipes 6 connected to the air inlet joint 5 in the water tank 2 through the air inlet joint 5, so that the refrigerated wastewater in the water tank 2 can pre-cool the smoke in the connecting pipes 6;

[0024] The heat-conducting shell 7 is arranged in the dust removal box 3 and a water tank 8 is provided between the dust removal box 3 and the heat-conducting shell 7. The water storage tank 2 and the dust removal box 3 are connected by a water pipe 9. The wastewater after cooling in the water storage tank 2 is injected into the water tank 8 through the water pipe 9, so that the wastewater in the water tank 8 can cool the heat-conducting shell 7 after absorbing the heat of the smoke.

[0025] The cooling component includes a transfer shell 10 and an air pipe 11. The transfer shell 10 is arranged on the surface of the water storage tank 2 and one end of a plurality of connecting pipes 6 is connected to the transfer shell 10. A dust removal filter element 12 for removing dust from smoke is provided in the heat conductive shell 7. One end of the air pipe 11 is connected to the transfer shell 10, and the other end passes through the dust removal box 3 and the heat conductive shell 7 and is connected to the dust removal filter element 12.

[0026] The other end of the dust removal filter element 12 is connected to an exhaust pipe 13, and the other end of the exhaust pipe 13 passes through the heat-conducting shell 7 and the dust removal box 3 and extends to the outside of the dust removal box 3. Temperature sensors 14 are provided in the heat-conducting shell 7 and the water tank 2. The heat-conducting shell 7 is made of aluminum and can quickly absorb the heat in the dust removal box 3. After the dust removal filter element 12 removes the dust, the removed dust can be discharged through the exhaust pipe 13 at one end.

[0027] A first water pump 15 is provided on the surface of the water pipe 9 and the first water pump 15 is connected to the bottom plate 1. The other end of the first water pump 15 is connected to the water tank 2 through a pipeline. A manual ball valve 16 is provided on the surface of the water pipe 9. The manual ball valve 16 can be used to manually control the on and off of the cooling water.

[0028] A second water pump 17 is provided on the surface of the base plate 1 and on one side of the dust removal box 3. One end of the second water pump 17 is connected to a pipe, and the pipe passes through the dust removal box 3 and extends into the water tank 8. The other end of the second water pump 17 is connected to a circulation pipe 18, and the other end of the circulation pipe 18 passes through the base plate 1 and is connected to the water storage tank 2. The second water pump 17 pumps the cooling waste water after absorbing heat in the water tank 8 into the circulation pipe 18, and the waste water is pumped into the water storage tank 2 through the circulation pipe 18 for collection. The waste water can be recycled, which greatly reduces the production cost.

[0029] A pneumatic regulating valve 19 is also provided on the surface of the water pipe 9 , and a water inlet joint 20 is provided on the top of the water tank 2 , which is connected to the purified wastewater pipeline through the water inlet joint 20 so that water can be injected into the water tank 2 .

[0030] The sewage circulation dust removal and cooling device purifies the sewage generated by dust removal, connects it to the water inlet joint 20 through a pipe, injects the purified wastewater into the water storage tank 2, and cools the wastewater in the water storage tank 2 through the refrigerator 4 to form cooling water. The air inlet joint 5 is connected to the smoke pipe generated by the processing. The smoke is dispersed into multiple connecting pipes 6 through the air inlet joint 5, and the surface of the connecting pipe 6 is wrapped by the cooling wastewater in the water storage tank 2. Therefore, the heat in the connecting pipe 6 can be quickly absorbed by the cooling wastewater, effectively cooling the smoke in the multiple connecting pipes 6, and preventing the smoke from being too hot when subsequently introduced into the dust removal box 3.

[0031] The smoke and dust entering the connecting pipe 6 is pre-cooled and then enters the transfer shell 10 and flows into the air pipe 11 of the transfer shell 10, thereby entering the dust removal filter 12 through one end of the air pipe 11 for dust removal. When the smoke and dust enter the dust removal filter 12, the remaining heat is dissipated and absorbed by the heat-conducting shell 7. When the temperature sensor 14 in the heat-conducting shell 7 detects that the temperature inside the heat-conducting shell 7 reaches 100°C, the temperature sensor 14 sends a control signal and transmits it to the first water pump 15 to control the operation of the first water pump 15. And the pneumatic regulating valve 19 is controlled to open. At this time, the first water pump 15 works to pump the cooling waste water in the water storage tank 2 into the water tank 8 through the water pipe 9, so that the cooling waste water in the water tank 8 can quickly absorb the heat on the surface of the heat-conducting shell 7, thereby cooling the dust removal box 3, avoiding the gradual increase in the temperature inside the dust removal box 3 and affecting the dust removal effect. When the temperature sensor 14 detects that the temperature inside the heat-conducting shell 7 is lower than 40°C, the first water pump 15 can be controlled to stop working, thereby realizing automatic cooling of the dust removal box 3.

[0032] After the cooling wastewater introduced into the water tank 8 absorbs heat, the second water pump 17 can be started to work. The second water pump 17 pumps the cooling wastewater that has absorbed heat in the water tank 8 into the circulation pipe 18, and is pumped into the water storage tank 2 through the circulation pipe 18 for collection. When the temperature sensor 14 in the water storage tank 2 detects that the wastewater temperature is higher than 20°C, the temperature sensor 14 sends a control signal and transmits it to the refrigerator 4 to control the refrigerator 4 to turn on. The cooling wastewater that has absorbed heat is cooled by the refrigerator 4, so that the wastewater in the water storage tank 2 can be recycled, avoiding waste of water resources, reducing energy consumption, and greatly reducing production costs. By observing the height of the water level line on the surface of the water storage tank 2, water can be replenished in time through the water inlet joint 20 when the water level is low.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
