DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0026] Refer to the attached Figure 1 -Attached Figure 6 A rolling roller automatic cooling device includes two cooling covers 100 symmetrically arranged up and down for mounting rolling rollers 600, a rolling channel is formed between the two cooling covers 100, and a water cooling device 400 is installed on the side wall of the cooling cover 100. By controlling the rotation of the two rolling rollers 600, the plate can be rolled. The plate is usually a high-temperature metal plate. During the continuous rolling process, the surface temperature of the rolling roller 600 increases, and the external dimensions and mechanical properties change. The rolling roller 600 can be cooled by the water cooling device 400 to ensure the continuous high-temperature rolling effect of the rolling roller 600.

[0027] The traditional water cooling device 400 generally achieves rapid cooling through a water-cooled spray structure, and has a good cooling effect. In order to realize the recycling of the cooling liquid, some designs will install a coolant recovery structure at the bottom; however, during the high-temperature rolling process, a certain proportion of the cooling liquid evaporates into gas and overflows from the outside. The traditional open or semi-open cooling structure is difficult to recover this part of the gaseous cooling medium, resulting in a waste of cooling liquid and the heat in the cooling liquid.

[0028] In order to solve the above problems, the improved cooling cover body 100 includes a containing body 110 with a rectangular cross-section, and a guide body 120 with a trapezoidal cross-section, and the water cooling device 400 is fixed to the side wall of the guide body 120; the upper end surface of the guide body 120 located at the top is installed with a negative pressure extraction device 300, and the lower end surface of the guide body 120 located at the bottom is installed with a filtering device 500; by designing the negative pressure extraction device 300, the volatilized gaseous cooling medium can be recovered from the top position, and by designing the filtering device 500, the liquid cooling medium after absorbing heat can be recovered from the bottom position, so that the cooling medium can be recycled and utilized to the greatest extent, thereby avoiding the loss of the cooling medium.

[0029] At the same time, the guide body 120 here has a contraction design, which can be located on both sides to guide the gaseous and liquid cooling media respectively, so as to realize the centralized and efficient recovery of the cooling media; and the negative pressure extraction device 300 here can centrally recover the gaseous cooling medium for heat exchange treatment, and can fully recover the heat contained in the gaseous cooling mechanism, thereby avoiding heat waste and saving resources.

[0030] It is preferred to arrange the water cooling device 400 into two symmetrical groups, which can spray cooling liquid toward the surface of the roller 600 from the front and rear directions to achieve efficient cooling of the cooling liquid; at the same time, a single group of water cooling devices 400 can be designed as multiple along the circumferential direction of the roller 600 to meet the cooling needs of the long-size roller 600.

[0031] Please refer to the attached Figure 5 Specifically, the water cooling device 400 includes a mounting rod 430 that passes through the guide body 120, a water-cooling nozzle 410 is fixed to the first end of the mounting rod 430, and a liquid delivery pipe 440 is fixed to the second end of the mounting rod 430. The cooling liquid can be transported through the liquid delivery pipe 440, and the cooling liquid is finally ejected from the water-cooling nozzle 410. The dispersed cooling liquid can act relatively evenly on the surface of the roller 600, thereby achieving efficient water cooling.

[0032] The mounting rod 430 is movably connected to the guide body 120 through the adjustment component 420. The distance between the water-cooling nozzle 410 and the guide body 120 is adjusted through the adjustment component 420. The position of the water-cooling nozzle 410 is adjusted according to the rolling temperature, rate and size of the rolling roller 600 to meet the water cooling requirements of high-temperature rolling under different conditions.

[0033] Please refer to the attached Figure 6 , specifically; the filtering device 500 includes a hollow filter channel 510, the inner wall of the filter channel 510 is mounted with a filter plate 530, the filter plate 530 can be used to filter the cooling liquid to remove impurities in the cooling liquid, to facilitate subsequent recycling of the cooling liquid.

[0034] Preferably, the filter plate 530 is set at an angle. The inclined filter plate 530 can extend the filtering area, and the filter residue can be collected along the filter plate 530 in a direction. A slag discharge port 511 is opened on the outside of the filter channel 510, and the slag discharge port 511 is located on the bottom side of the filter plate 530. The slag discharge port 511 is closed under normal circumstances to ensure the normal flow of the slag discharge port 511. When there is too much filter residue stored at the slag discharge port 511, the slag discharge port 511 is opened to ensure that the filter plate 530 can filter the cooling liquid normally.

[0035] An air supply device 520 is installed on the inner wall of the filter channel 510. The air supply device 520 is located at the bottom of the filter plate 530. The air can be blown toward the filter plate 530 through the air supply device 520, which can further act on the filter residue blocked at the sieve holes of the filter plate 530, thereby accelerating its directional rolling collection. At the same time, the bottom of the filter channel 510 is relatively sealed, and a directional airflow can be formed between the air supply device 520 and the negative pressure extraction device 300 at the top to accelerate the unidirectional collection of the gaseous cooling medium, thereby improving the efficiency of the negative pressure extraction device 300 in collecting the cooling medium and exchanging heat.

[0036] A sealing device 200 is installed on the outer side wall of the cooling cover body 100, and a sealed channel is formed between the two sealing devices 200. By setting the sealing device 200, the sealing length between the two can be extended to enhance the sealing effect between the two cooling cover bodies 100 and avoid losses caused by leakage of gaseous cooling medium.

[0037] Specifically, the sealing device 200 includes a first sealing plate 210 extending longitudinally and a second sealing plate 220 extending transversely. By arranging the first sealing plate 210 and the second sealing plate 220, the sealing effect in two directions can be extended to avoid leakage of gaseous cooling gas. By arranging the sealing plate structure suitable for high-temperature rolling environment, the sealing ring can be set at the outer position to extend its aging failure time.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
