[0002] A rolling mill is a mechanical device that realizes the metal rolling process. It generally refers to equipment that completes the entire process of rolled material production, including main equipment, auxiliary equipment, lifting and transportation equipment, and ancillary equipment, among which is spray cooling equipment. When rolling bars, a heating furnace is needed to heat the bars to a certain temperature. When heated to the required temperature, the bars are transported to the bar rolling mill for rolling using conveyor rollers. During the transportation of the bars, an oxide layer will form on the surface of the steel due to the coldness of the steel. Existing equipment will use a high-pressure spray cooling water gun to wash away the oxide layer, to prevent the rolling mill from pressing the oxide layer into the steel and reducing the quality of the steel during subsequent rolling.

However, the device cannot roll the steel at the same time when removing the iron oxide filings on the surface of the rod-shaped steel, and the processing efficiency is low. The existing high-pressure spray cooling water gun has a small range of action when removing the oxide layer, and it is difficult to remove the oxide layer on the bottom and side of the rod-shaped steel. In addition, the water mist generated after spraying easily absorbs dust and is absorbed by on-site workers, making it difficult to ensure the health of on-site workers. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. A peeling cooling component is provided, which drives the moving screw rod to rotate by controlling the moving motor. Under the limiting effect of the limiting slide rod and the limiting ear and the connection driving effect of the lifting swing frame, the moving motor can drive the annular box to move to the position where the steel is to pass, and the cooling water is transported to the inside of the annular box by the water pump to cooperate with the rotating motor to drive the gear ring to rotate. Under the connection driving effect of the connecting rod, the rotating motor drives the annular sealing ring and the spray head to rotate. The high-pressure water flow sprayed by the spray head can flush any position on the surface of the steel to avoid the oxide layer remaining on the surface of the steel. During the subsequent rolling, the oxide layer is prevented from being pressed into the inside of the steel, thereby improving the rolling quality of the product. At the same time, the adjusting slide rod is driven to reciprocate along the sliding frame by the swinging electric push rod. Under the rotation connection effect of the swinging swivel seat, the annular box reciprocates around the swinging shaft, so that the high-pressure water flow sprayed by the spray head can flush the gap between the oxide layer and the steel, making it easier for the oxide layer to fall off the steel, thereby further improving the rolling quality of the product.

[0021] Before the steel is conveyed to the inside of the annular box, the knocking plate is driven up and down by the lifting electric push rod. Under the connection buffering action of the connecting spring, the steel conveyed on the conveying roller can be flexibly knocked to break the oxide layer on the steel, making it easier to remove the oxide layer later and avoiding the oxide layer from remaining on the steel, further improving the subsequent product rolling quality. At the same time, the high-temperature water mist generated after cooling can enter the mask tube and the dust tube through the dust suction port and the docking suction port, and enter the insulation tank through the dust suction pipe and the air suction metal hose, avoiding the dust-containing water mist from being absorbed by the on-site staff, ensuring the health of the on-site staff and making the processing more environmentally friendly. At the same time, under the connection driving action of the swing plate, the lifting electric push rod also drives the dust tube to swing around the central rotating axis, so that the absorption range of the dust suction port is wider, the dust removal effect is better, and the health of the on-site staff is further guaranteed.

[0022] 2. A recycling and processing component is provided. When the external water pump delivers water to the water delivery metal hose, the cooling water will flow through the shunt pipe and the inside of the water collecting box. The cooling water will come into contact with the hot and humid air in the process of passing through the shunt pipe. The shunt pipe and the heat-conducting copper sheet are made of copper and have good thermal conductivity. Under the action of heat conduction, the hot and humid air can heat the cooling water flowing through the inside of the shunt pipe, so that the cooling water reaches a suitable cooling temperature. While recycling the heat, the quality of the steel is further improved. Cold water is stored in the water storage tank. When the hot and humid air is cooled, the moisture in the air condenses into water droplets and drips into the condensation box. A collection device is placed at the water outlet of the condensation pipe to collect the water. The collected water can be recycled, making the processing more environmentally friendly.

[0023] When the filter element needs to be cleaned, the electric control valve is closed to control the conversion electric push rod to drive the shielding tube to move to expose the self-cleaning spray hole, and water is transported to the inside of the shunt pipe through an external water pump. The transported water is sprayed out from the self-cleaning spray hole to clean the filter element. There is no need to manually remove the filter element for cleaning, which is convenient and quick.

[0024] Under the connecting drive of the linkage rod, the mobile motor also drives the sealing sleeve to move synchronously, so that the follower nozzle on the sealing sleeve corresponds to the corresponding cooling nozzle, so that the gas discharged by the air pump can be ejected from the follower nozzle through the exhaust pipe, the injection pipe and the cooling nozzle. The ejected gas can be concentrated and blown to the steel at the bottom to avoid the oxide layer remaining on the surface of the steel. At the same time, it can also cool the steel, further ensuring the subsequent rolling quality.

[0025] In summary, in the peeling and cooling component, the high-temperature water mist generated after cooling can enter the insulation tank through the mask tube and the dust collection tube, preventing the dust-containing water mist from being absorbed by the on-site staff, thus ensuring the health of the on-site staff. The heat and moisture of the humid hot air can be utilized in the recycling and processing component. The two components cooperate with each other to make the processing system more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

Under the connection and driving action of the linkage rod 524, the linkage rod 524 can drive the sealing sleeve 522 to move synchronously, so that the follower spray hole 523 on the sealing sleeve 522 corresponds to the corresponding cooling spray hole 521, so that the gas discharged by the air pump 514 can be sprayed from the follower spray hole 523 through the exhaust pipe 519, the air jet pipe 520 and the cooling spray hole 521, and the sprayed gas can be concentrated and blown to the steel at the bottom, so as to avoid the oxide layer remaining on the surface of the steel, and further ensure the subsequent rolling quality;

[0055] A filtered water tank 525 is installed at the top of the assembly base 1 and at the bottom of the dust collection tube 428 and the jet pipe 520. A filter plate 526 is installed at the bottom inside the filtered water tank 525. The other end of the return pipe 513 is located on one side of the top of the filtered water tank 525. The water for flushing the oxide layer and the water inside the insulation tank 501 can flow into the filtered water tank 525. The filter plate 526 can filter the water, which is convenient for recycling the water.

[0056] The working principle and use process of the present invention are as follows: when in use, according to the size of the steel to be rolled, the moving motor 424 is started, and the moving motor 424 is controlled to drive the moving screw 423 to rotate. Under the limiting action of the limiting slide bar 425 and the limiting ear 427, the moving motor 424 drives the translation frame 426 to move along the limiting slide bar 425. Under the connection and driving action of the hanging swing frame 417, the adjusting sleeve 404 and the ring box 406 are moved along the adjusting slide bar 402, so that the ring box 406 moves to the position where the steel is to pass, so that the steel During the process of being transported to the rolling mill 2 by the conveying roller 3, the steel can pass through the annular box 406. At the same time, the translation frame 426 can also synchronously drive the sealing slider 431 to move inside the dust suction cylinder 528, so that the docking suction port 433 at the bottom of the mask cylinder 432 corresponds to the corresponding dust suction port 429. When the steel passes the bottom of the knocking plate 444, the air pump 514, the lifting electric push rod 438 and the external water pump are started. The lifting electric push rod 438 drives the connecting ear 439 to move up and down, and also drives the knocking plate 444 to move up and down. Under the action of the connection buffer, the steel conveyed on the conveying roller 3 can be flexibly knocked. Under the knocking action of the knocking plate 444, the oxide layer on the steel can be broken, making it easier to remove the oxide layer later, avoiding the oxide layer from remaining on the steel, and improving the quality of subsequent product rolling. At the same time, the external water pump conveys cooling water to the inside of the annular box 406 through the water delivery metal hose 419, and the cooling water is sprayed from the spray head 409. The sprayed cooling water is sprayed onto the surface of the steel to cool the steel. At the same time, under the impact of the high-pressure water flow, the oxide layer on the surface of the steel is The steel falls off the steel, and the rotating motor 415 is started. Under the driving action of the bevel gear 414, the driving gear 413 drives the gear ring 410 to rotate. Under the connecting driving action of the connecting rod 411, the gear ring 410 drives the annular sealing ring 408 and the spray head 409 to rotate. The high-pressure water flow sprayed by the spray head 409 can flush any position on the surface of the steel, avoiding flushing dead corners, avoiding the oxide layer remaining on the surface of the steel, and avoiding the oxide layer from being pressed into the steel during subsequent rolling, thereby further improving the rolling quality of the product;

[0057] At the same time, under the connection driving action of the swing plate 436, the lifting electric push rod 438 also drives the dust suction cylinder 428 to swing around the central axis, thereby driving the dust suction port 429 to swing, so that the dust suction port 429 has a wider absorption range and a better dust removal effect, further protecting the health of the on-site staff and making the processing more environmentally friendly;

[0058] At the same time, the swing electric push rod 403 is started, and the swing electric push rod 403 drives the adjustment slide rod 402 to reciprocate along the slide frame 401. Under the rotation connection of the swing rotating seat 405, the annular box 406 reciprocates around the swing shaft 418, so that the high-pressure water flow sprayed by the spray head 409 can flush the gap between the oxide layer and the steel, making it easier for the oxide layer to fall off the steel, further improving the rolling quality of the product;

[0059] When cooling the steel, the high-temperature steel contacts with water to generate water mist, which absorbs oxide dust. The air pump 514 is started, and the high-temperature water mist enters the shield tube 432 through the dust suction port 429 and the docking suction port 433, and then enters the insulation tank 501 through the dust suction pipe 434 and the air suction metal hose 435, so as to prevent the water mist containing dust from being absorbed by the on-site staff, thereby ensuring the health of the on-site staff. The air entering the insulation tank 501 is filtered by the filter element 512, and the clean air enters the U-shaped tube 515. Cold water is stored in the water storage tank 517. When the humid and hot air is cooled, the moisture in the air condenses into water droplets and drips into the condensation box 516, and finally is discharged from the condensation tube 518. A collection device is placed at the water outlet of the condensation tube 518 to collect the water, and the collected water can be recycled.

[0060] When the filter element 512 needs to be cleaned, the electric control valve 503 is controlled to be closed, and the conversion electric push rod 511 is started. The conversion electric push rod 511 drives the shielding tube 508 to move, and the self-cleaning spray hole 507 is exposed. The external water pump is started, and the water transported to the inside of the shunt tube 505 is sprayed out from the self-cleaning spray hole 507. The sprayed water cleans the filter element 512, and there is no need to manually remove the filter element 512 for cleaning, which is convenient and quick.

[0061] When the external water pump delivers water to the water delivery metal hose 419, the cooling water will flow through the water delivery pipe 506 into the water collecting box 504 on one side, then flow through the shunt pipe 505 into the water collecting box 504 on the other side, and finally enter the water delivery metal hose 419 through the electric control valve 503. The cooling water will come into contact with the humid hot air in the process of passing through the shunt pipe 505. The shunt pipe 505 and the heat-conducting copper sheet 509 are both made of copper and have good thermal conductivity. Under the action of heat conduction, the humid hot air can heat the cooling water flowing through the shunt pipe 505, so that the temperature of the cooling water reaches between 20 degrees Celsius and 35 degrees Celsius, so that the cooling water reaches a temperature suitable for cooling, and the heat is recycled while further improving the quality of the steel.

[0062] The jet pipe 520 is located on one side of the assembly frame 421, and can utilize the cooling gas discharged by the air pump 514. Under the connection and driving action of the linkage rod 524, the linkage rod 524 can drive the sealing sleeve 522 to move synchronously, so that the follower nozzle 523 on the sealing sleeve 522 corresponds to the corresponding cooling nozzle 521, so that the gas discharged by the air pump 514 can be ejected from the follower nozzle 523 through the exhaust pipe 519, the jet pipe 520 and the cooling nozzle 521. The ejected gas can be concentrated and blown to the steel at the bottom to avoid an oxide layer remaining on the surface of the steel. At the same time, the steel can also be cooled, further ensuring the subsequent rolling quality.

[0063] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
