[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0034] The following describes the noun part of the coil cooling bed 100 and the coil production line according to the present application with reference to the drawings.

[0035] like Figure 1 and Figure 2As shown, a coil cooling bed 100 is provided in a specific embodiment of the present application. A spray device is provided on the upstream side of the coil cooling bed 100 along the coil conveying direction. The spray device is used to spray water to the coil to generate high-temperature water. The coil cooling bed 100 includes a cooling trough 1 and a diverter trough 2, wherein the cooling trough 1 is provided with coil conveying rollers 3 arranged at intervals along the coil conveying direction; the diverter trough 2 has an upper opening and a liquid outlet, the upper opening is arranged on the upstream side of the cooling trough 1 along the coil conveying direction, and the liquid outlet is used to discharge the high-temperature water flowing in from the upper opening.

[0036] In the production process of asphalt coils, the coil cooling bed 100 is filled with a cooling tank 1 filled with a low-temperature coolant for cooling to solidify the coil. In order to ensure that the coil can obtain a good cooling and solidification effect, it is necessary to spray water through a spray device for preliminary cooling before entering the coil cooling bed 100. The water sprayed on the coil absorbs heat and its temperature rises sharply to form high-temperature water and drips from the coil. In the present application, the high-temperature water is collected and discharged by the diversion tank 2 arranged in front of the cooling tank 1, so as to avoid the high-temperature water dripping into the cooling tank 1 and causing the temperature of the low-temperature coolant to rise, thereby improving the cooling effect of the cooling water bed.

[0037] It should be noted that, in the specific embodiment of the present application, unless otherwise specified, the coil cooling bed 100 extends along the conveying direction of the coil, the length direction of the coil cooling bed 100 is the front-to-back direction, the width direction of the coil cooling bed 100 is the left-to-right direction, and the height direction of the coil cooling bed 100 is the up-down direction, wherein the diverter slot 2 is located at the front side of the cooling slot 1, and the slot opening of the cooling slot 1 faces upward.

[0038] In a specific embodiment of the present application, the coil cooling bed 100 includes a bed plate 11 extending in the front-to-back direction, a left side plate 12 and a right side plate 13 connected to the left and right ends of the bed plate 11, respectively, and the bed plate 11, the left side plate 12 and the right side plate 13 form a water tank. A bed frame for supporting the upper structure is provided at the bottom of the bottom plate 11.

[0039] Specifically, the coil cooling bed 100 also includes a partition plate 4 extending upward, which is arranged near the front end of the bed plate 11, the lower end of the partition plate 4 is connected to the bed plate 11, and the left and right ends of the partition plate 4 are respectively connected to the left side plate 12 and the right side plate 13. The partition plate 4 separates the water trough into a cooling trough 1 and a diversion trough 2. The notches of the cooling trough 1 and the diversion trough 2 are both arranged upward, and the diversion trough 2 is located at the front side of the cooling trough 1. The partition plate 4 serves as the rear side wall of the diversion trough 2 and the front side wall of the cooling trough 1. The cooling trough 1 and the diversion trough 2 are formed by setting the partition plate 4 to separate the bed plate 11, thereby ensuring that the diversion of high-temperature water is completed without increasing the size of the coil cooling bed 100, thereby reducing the footprint of the coil cooling bed 100.

[0040] Preferably, the angle formed by the partition plate 4 and the bottom wall of the cooling tank 1 is an obtuse angle. The partition plate 4 is tilted forward to prevent high-temperature water from splashing into the cooling tank 1 when dripping from the coil, thereby avoiding the temperature increase of the low-temperature coolant in the cooling tank 1, thereby improving the cooling effect of the cooling water bed.

[0041] Furthermore, the coil cooling bed 100 also includes a bottom partition 6 extending along the conveying direction of the coil, the bottom partition 6 is located above the bed plate 11 and is arranged parallel to the bed plate 11, the left and right ends of the bottom partition 6 are respectively connected to the left side plate 12 and the right side plate 13, and the front end of the bottom partition 6 is connected to the partition plate 4. At this time, the bottom partition 6 serves as the bottom wall of the cooling trough 1 to form a cooling trough 1 with the left side plate 12 and the right side plate 13, and the bottom partition 6 also serves as the top wall of the liquid outlet channel 5 to form a liquid outlet channel 5 with the partition plate 4, the left side plate 12 and the right side plate 13, and the liquid outlet is opened on the partition plate 4 and connected to the liquid outlet channel 5.

[0042] In the present application, high-temperature water is collected by the diverter trough 2 and flows out from the liquid outlet to the liquid outlet channel 5, thereby avoiding the accumulation of high-temperature water in the diverter trough 2, which causes the temperature of the cooling liquid in the cooling trough 1 to rise, thereby improving the cooling effect of the cooling water bed. In addition, by arranging the liquid outlet channel 5 below the cooling trough 1, it is ensured that the high-temperature water is discharged without increasing the size of the coil cooling bed 100, thereby reducing the footprint of the coil cooling bed 100.

[0043] Those skilled in the art will appreciate that the present application is not limited to the above-mentioned structural arrangement in which the liquid outlet channel 5 is disposed at the bottom of the cooling trough 1 and the liquid outlet is opened on the partition plate 4. It may also be other structural arrangements in which the liquid outlet is opened on the bottom wall of the diversion trough 2 and connected to the liquid outlet channel 5, etc., which can realize the discharge of high-temperature water. Other structural arrangements should also fall within the scope of protection of the present application.

[0044] Preferably, a plurality of support members 7 are provided between the bottom baffle 6 and the bottom wall of the liquid outlet channel 5. Since the bottom baffle 6 serves as the bottom wall of the cooling tank 1, it is necessary to support a plurality of structural members in the cooling tank 1. The support members 7 are provided to strengthen the supporting force of the bottom baffle 6, thereby ensuring the stability of the coil cooling bed 100.

[0045] It should be noted that the structural form of the support member 7 is not limited, and can be a variety of structural forms such as a cube, a cylinder, etc., and various structural forms all fall within the protection scope of this application.

[0046] In some embodiments, the coil cooling bed 100 further includes a guide plate 8 as the front side wall of the diverter trough 2. The angle formed by the guide plate 8 and the bottom wall of the diverter trough 2 is an obtuse angle. The guide plate 8 is provided to guide high-temperature water into the diverter trough 2.

[0047] Furthermore, auxiliary guide plates are provided on the other side walls of the diversion trough 2. Since the area of ​​the coil is large, the dripping range of the high-temperature water formed after the water is sprayed onto the coil is large. The auxiliary guide plates and the guide plates 8 are used to collect the high-temperature water dripping in a large range, thereby preventing the high-temperature water from dripping onto the ground.

[0048] In some embodiments, a plurality of water spray members 9 are arranged at intervals on the bottom wall of the cooling trough 1 along the conveying direction of the coil, and a plurality of water spray holes for spraying cooling liquid are opened on the water spray members 9. The plurality of water spray members 9 and the plurality of coil conveying rollers 3 are arranged alternately at intervals.

[0049] Specifically, the water spray member 9 extends in the left-right direction and passes through the left plate 12 and / or the right plate 13 to be connected to the water source. The left and right ends of the coil conveying roller 3 are respectively connected to the left plate 12 and the right plate 13. When the coil is conveyed on the coil conveying roller 3, the liquid level of the cooling liquid in the cooling trough 1 is higher than the height of the coil, thereby ensuring that the coil can be fully cooled by the cooling liquid, thereby improving the cooling effect of the cooling water bed.

[0050] Furthermore, an overflow member 10 for preventing the cooling liquid from splashing is provided on the water spray member 9 , and an overflow gap for the cooling liquid to flow out is formed between the overflow member 10 and the side wall of the cooling tank 1 .

[0051] Preferably, the overflow member 10 includes two spliced ​​overflow plate portions, the two overflow plate portions extend in the left-right direction, and mounting members 14 are respectively provided on the front and rear sides of the water spray member 9. The two side walls of the two overflow plate portions that are away from each other are respectively connected to the two mounting members 14, and the left and right ends of the overflow plate portions form overflow gaps with the left plate 12 and the right plate 13 respectively.

[0052] Those skilled in the art will appreciate that the present application is not limited to the structural form of the overflow member 10 described above, but may also be an overflow member 10 that is directly provided with an overflow groove, and may have overflow holes on the overflow member 10, and other structural forms that can prevent the cooling liquid from splashing. Other structural forms should also fall within the scope of protection of the present application.

[0053] It should be noted that the structures of the water spraying member 9 for spraying cooling liquid and the mounting member 14 for mounting the overflow member 10 are well known to those skilled in the art and do not belong to the core improvement part of the present application, and thus will not be described in detail here.

[0054] The specific embodiment of the present application also provides a coil production line, including a coil cooling bed 100 and a spray device. The spray device is arranged above the diverter trough 2 of the coil cooling bed 100. When the coil with a higher temperature after the previous process is transported to the front end of the coil cooling bed 100, the spray device sprays water on the top and bottom surfaces of the coil for preliminary cooling. The water sprayed on the coil absorbs the heat of the coil and then heats up to form high-temperature water, which directly drips into the diverter trough 2 for diversion, thereby preventing high-temperature water from entering the cooling trough 1 and raising the temperature of the cooling liquid in the cooling trough 1, thereby ensuring the cooling and curing effect of the coil cooling bed 100 to improve the quality of the coil. Since the coil production line adopts all embodiments of the coil cooling bed 100, the coil production line has all the beneficial effects brought by the coil cooling bed 100.

[0055] In some embodiments, the spray device includes a plurality of water spray rods 15, and the plurality of water spray rods 15 include a plurality of upper water spray rods and a plurality of lower water spray rods. The upper water spray rods are located above the coil, and the lower water spray rods are located below the coil. The upper water spray rods are used to spray water to cool the upper surface of the coil, and the lower water spray rods are used to spray water to cool the lower surface of the coil, thereby achieving simultaneous cooling of the upper and lower surfaces of the coil, thereby improving the cooling effect of the coil.
