Description

Technical Field

[0001] This utility model relates to the technical field of alloy steel heat treatment equipment, and in particular to a rotating mist cooling device for the surface of alloy steel after heat treatment. Background Technology

[0002] After heat treatment, alloy steel needs to be cooled quickly and evenly to ensure its performance. Traditional water cooling is prone to surface cracking, and air cooling is inefficient. Rotary mist cooling is the preferred option because of its uniform cooling. However, existing equipment is difficult to meet the all-round cooling needs of large-size alloy steel, and the problems of water resource recovery and impurity removal are prominent.

[0003] Existing rotary mist cooling devices have significant drawbacks. Traditional devices typically consist of a fixed housing and a single atomizing nozzle, with alloy steel transported only in a straight line, resulting in limited cooling surface area. For thick-walled alloy steel, uneven cooling can easily occur, leading to performance differences. The limiting components are rudimentary, causing the alloy steel to easily shift during rotation, affecting cooling accuracy. Wastewater collection lacks filters and water pump circulation, resulting in significant water waste, and impurities accumulate in the guide channel, hindering heat dissipation. The absence of an automatic scraping component makes the filters prone to clogging, requiring frequent manual cleaning and reducing production efficiency. Ultimately, this leads to uneven cooling and difficulty in removing impurities. Therefore, this application designs a rotary mist cooling device for the surface of alloy steel after heat treatment to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Limiting components are provided at each of the four corners of the mounting frame 5. A wastewater collection component is provided at the lower end of the interior of the housing 1, and a scraping component is provided at the upper end of the wastewater collection component. The housing 1 provides cooling space, the cooling box 2 stores cooling water, the mounting frame 5 drives the alloy steel to rotate, the limiting components fix the alloy steel, the wastewater collection component recovers wastewater, and the scraping component cleans impurities, thereby improving cooling efficiency and resource utilization. A rotating shaft is provided at one end of the mounting frame 5, and a through hole on one side of the rotating shaft is used to install... A first motor 3 is provided, with its output shaft coaxially fixed to the rotating shaft. Multiple guide rollers are equidistantly mounted on the inner side of the mounting frame 5. The first motor 3 drives the rotating shaft to rotate the mounting frame 5, facilitating all-round cooling and improving cooling uniformity. A bracket 10 is installed on the upper inner side of the housing 1, with a water pipe inside the bracket 10. Multiple atomizing nozzles 11 are equidistantly mounted on the lower end of the bracket 10. A first water pump 6 is installed on the upper end of the cooling box 2, with its output water pipe connected to the bracket 10. The first water pump 6 transports water from the cooling box 2 to the bracket 10 via the water pipe, and the atomizing nozzles 11 atomize and spray the water onto the alloy steel surface, facilitating uniform cooling and enhancing the cooling effect.

[0020] In this invention, the wastewater collection assembly consists of a guide channel 9 and a filter screen 13. An inclined plate is located at the lower end of the interior of the housing 1, with the guide channel 9 positioned at the end of the inclined plate. The filter screen 13 is installed at the upper end of the guide channel 9. A second water pump 7 is installed on the side of the cooling tank 2, and the output water pipe of the second water pump 7 is connected to the end of the guide channel 9. The inclined plate guides wastewater into the guide channel 9, the filter screen 13 filters impurities, and the second water pump 7 pumps the filtered water back to the cooling tank 2 for recycling, thus saving water resources. A second motor 4 is installed on the side of the housing 1, and a collection basket 8 is installed at the other end of the housing 1. The scraping assembly consists of a scraper 14 and a lead screw inside the housing 1. The scraper 14 is slidably positioned above the filter screen 13, and the lead screw is threadedly connected to the scraper 14. One end of the lead screw is coaxially fixed to the output shaft of the second motor 4; the second motor 4 drives the lead screw to slide the scraper 14, clean the impurities on the filter screen 13 and push it into the collection basket 8, preventing the filter screen 13 from clogging and ensuring smooth wastewater recycling; both sides of the mounting frame 5 are provided with placement slots, and a connecting rod 15 is hinged to the middle of the inner side of the placement slot. Both ends of the connecting rod 15 are provided with limiting components, which consist of a limiting block 12 and an electric push rod 16. The side end of the limiting block 12 is hinged to one end of the connecting rod 15, and the electric push rod 16 is installed at the lower end of the limiting block 12; the electric push rod 16 pushes the limiting block 12 to clamp the alloy steel, and the connecting rod 15 extends and retracts with the electric push rod 16 to adjust the angle, ensuring the stability of the alloy steel feeding and discharging and the limiting, and preventing the alloy steel from shifting.

[0021] Working principle: When using the rotating mist cooling device for the surface of heat-treated alloy steel, first turn on the power and start the electric push rod 16 to raise the limiting block 12 at the feed port end. Then, the heat-treated alloy steel is placed into the mounting frame 5 through the through hole at one end of the housing 1 along the guide rollers that are equidistantly installed inside the mounting frame 5. Next, start the electric push rod 16 again. The electric push rod 16 pushes the limiting block 12. At the same time, the limiting block 12, with the cooperation of the connecting rod 15 hinged to the middle of the inner side of the slot on both sides of the mounting frame 5, allows the limiting blocks 12 at both ends of the mounting frame 5 to clamp the alloy steel synchronously. Then, the first motor 3, installed at the lower end of the through hole on one side of the rotating shaft, is started. The output shaft of the first motor 3 is coaxially fixed to the rotating shaft at one end of the mounting bracket 5, thereby driving the rotating shaft to rotate the mounting bracket 5 inside the housing 1. At the same time, the first water pump 6, installed at the upper end of the cooling tank 2, is started. The first water pump 6 delivers the cooling water stored in the cooling tank 2 to the bracket 10 installed at the upper end of the inner side of the housing 1. The cooling water flows through the water pipe inside the bracket 10 to multiple atomizing nozzles 11 installed at equal intervals at its lower end. After being atomized by the atomizing nozzles 11, it is sprayed onto the rotating alloy steel surface. The cooling process achieves uniform cooling. Wastewater generated during cooling flows along an inclined plate at the lower end of the chamber 1, eventually flowing into a guide channel 9 at the end of the inclined plate. After impurities are filtered by a filter screen 13 installed at the upper end of the guide channel 9, a second water pump 7 installed on the side of the cooling chamber 2 is activated. The second water pump 7 is connected to the end of the guide channel 9 via an output water pipe, pumping the filtered wastewater back into the cooling chamber 2 for recycling. When the impurities accumulated on the filter screen 13 reach a certain level, a second motor 4 installed on the side of the chamber 1 is activated. The output shaft of the second motor 4... The screw is coaxially fixed to the lead screw inside the housing 1, and the lead screw is driven to rotate, so that the scraper 14, which is threaded to the lead screw and slidably disposed on the upper end of the filter screen 13, slides along the surface of the filter screen 13, pushing the impurities into the collection basket 8 installed at the other end of the housing 1; after the alloy steel has cooled down, the first motor 3, the second motor 4, the first water pump 6 and the second water pump 7 are turned off, and the electric push rod 16 is started to raise the limiting block 12 at the discharge end, so that the cooled alloy steel can be taken out from the through hole at the other end of the housing 1. Finally, the impurities in the collection basket 8 are cleaned, thus completing the entire process.
