Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a water-saving MULPIC cooling device. Background Technology

[0002] In the hot rolling industry of iron and steel metallurgy, MULPIC is a common product control cooling process and equipment. It is an important device for adjusting and controlling the internal properties of steel plates (strips) after hot rolling.

[0003] Currently, in the field of steel plate production and cooling processing, due to the rapid heat dissipation and high cooling intensity at the edges of steel plates, the common practice during cooling is to use "edge shielding," which involves using an "umbrella" to block the cooling water from directly hitting the steel plate. This reduces the amount of cooling water at the edges of the hot steel plate, thereby achieving consistent internal properties. However, conventional "edge shielding" involves setting up long, longitudinal baffles between the hot steel plate and the upper cooling manifold to block the cooling water sprayed towards the edges of the steel plate. This structure only prevents cooling water from hitting the hot steel plate and cannot avoid the waste of this water. Therefore, we propose a water-saving MULPIC cooling device. Utility Model Content

[0004] The main objective of this invention is to provide a water-saving MULPIC cooling device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a water-saving MULPIC cooling device, comprising a cooling box with a cover on top. A handle is rotatably connected to the side wall of the cooling box, and a lead screw is fixedly connected to the handle. The lead screw is rotatably connected to the inner wall of the cooling box, and an adjusting plate is threaded onto the lead screw. Inlet and outlet pipes are distributed and connected to the side wall of the cooling box. By providing an adjustable set of adjusting plates on each side of the interior of each cooling box, the interior is divided into a central area and two side areas. The central area can be set according to a predetermined cooling rate. The cooling water volume is used to cool a specific central area of ​​the steel plate or strip. The central area can receive cooling water from zero to any set value. The two side areas allow a small amount of water leaking from the wear and tear of the adjusting plate to be channeled into the return water. By adjusting the adjusting plate laterally, cooling water can be ensured only in the central area of ​​the steel plate, while flexibly shielding the non-cooled areas on both sides of the steel plate. This accommodates steel plates of different widths without wasting cooling water. The cooling box is equipped with an auxiliary mechanism, which includes a through groove on the inner wall of both sides of the cooling box.

[0006] Preferably, a fixing plate is fixedly connected to the bottom of the box cover, and the side wall of the fixing plate is provided with a through groove.

[0007] Preferably, the through groove is slidably connected to a sliding plate, the sliding plate is fixedly connected to a limiting plate, the limiting plate is fixedly connected to an elastic telescopic rod in the middle, and the end of the elastic telescopic rod away from the middle of the limiting plate is fixedly connected to the box cover.

[0008] Preferably, a sliding groove is provided below the box cover, and a correction plate is slidably connected to the sliding groove.

[0009] Preferably, the side wall of the correction plate is provided with a through groove three, and the through groove three is slidably connected to the sliding plate.

[0010] Preferably, a spring is fixedly connected to the side wall of the correction plate, and the end of the spring away from the side wall of the correction plate is fixedly connected to the side wall of the fixing plate.

[0011] Preferably, an auxiliary plate is fixedly connected to the bottom of the cooling box. By aligning the sliding plates on both sides of the box cover with the through groove one on the inner wall of the cooling box and inserting them, when the sliding plate touches through groove one, the sliding plate will move upward along through groove two. The upward movement of the sliding plate will drive the limiting plate fixedly connected to it to move upward as well, so that the limiting plate moves to the top of through groove three. At this time, the position limit of the two sets of correction plates can be released. Under the elastic reset action of the spring, the two sets of correction plates will drive the steel plate on the auxiliary plate to clamp and correct the deviation. The operation is simple and convenient.

[0012] This invention provides a water-saving MULPIC cooling device. It has the following beneficial effects:

[0013] (1) The water-saving MULPIC cooling device is divided into a central area and two side areas by setting an adjustable adjustment plate on each side inside the cooling box. The central area can be set with a cooling water volume according to the set cooling rate to cool a specific area in the middle of the steel plate or strip. The central area can provide the steel plate with a cooling water volume from zero to any set value. The two side areas allow the small amount of water leaked by the seal wear of the adjustment plate to be returned to the return water. By adjusting the adjustment plate laterally, only the central area of ​​the steel plate can be cooled with water, while the non-cooled areas on both sides of the steel plate can be flexibly shielded. It can adapt to steel plates of different widths without wasting cooling water.

[0014] (2) The water-saving MULPIC cooling device inserts the sliding plates on both sides of the box cover into the through groove 1 on the inner wall of the cooling box. When the sliding plate touches through groove 1, the sliding plate will move upward along through groove 2. The upward movement of the sliding plate will drive the limiting plate fixedly connected to it to move upward as well. Thus, the limiting plate moves to the top of through groove 3. At this time, the position limit of the two sets of correction plates can be released. Under the elastic reset action of the spring, the two sets of correction plates will clamp and correct the steel plate on the auxiliary plate. The operation is simple and convenient.

[0015] (3) The water-saving MULPIC cooling device can make the limiting plate snap between the two sets of correction plates by the elastic reset of the elastic telescopic rod, which facilitates the next steel plate correction operation. Attached Figure Description

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model proposes a water-saving MULPIC cooling device, including a cooling box 1, a box cover 2 on top of the cooling box 1, threaded holes around the cooling box 1 and the box cover 2, and bolts threaded into the threaded holes. A handle 3 is rotatably connected to the side wall of the cooling box 1, and a lead screw 4 is fixedly connected to the handle 3 and rotatably connected to the inner wall of the cooling box 1. An adjusting plate 5 is threadedly connected to the lead screw 4. A water inlet pipe 6 and a water outlet pipe 7 are distributed and connected to the side wall of the cooling box 1. By setting an adjustable adjusting plate 5 on each side inside the cooling box 1, the interior of the cooling box 1 is divided into a central area and two side areas. The cooling water volume in the central area can be set according to a set cooling rate to cool a specific central area of ​​steel plate or strip. The central area can provide the steel plate with a cooling water volume from zero to any set value. The two side areas... The small amount of water leaking from the seal wear of the regulating plate 5 is introduced into the return water. By adjusting the regulating plate 5 laterally, cooling water can be provided only in the middle area of ​​the steel plate, while the non-cooled areas on both sides of the steel plate can be flexibly shielded. This method can adapt to steel plates of different widths without wasting cooling water. Specifically, when the steel plate needs to be shielded at the edges, the handle 3 should be turned forward to drive the screw 4 to rotate forward, so that the two sets of regulating plates 5 are brought closer to the steel plate, thereby shielding the edges of the steel plate. When the steel plate does not need to be shielded at the edges, the handle 3 should be turned in the opposite direction to drive the screw 4 to rotate in the opposite direction, thereby widening the distance between the two sets of regulating plates 5, thus moving them away from the edges of the steel plate. The cooling box 1 is equipped with an auxiliary mechanism 9, which includes a through groove 91, which is located on the inner walls of both sides of the cooling box 1.

[0027] In this embodiment of the utility model, in order to enable the auxiliary mechanism 9 to operate better, a fixing plate 92 is fixedly connected to the bottom of the box cover 2. The side wall of the fixing plate 92 is provided with a through groove 93. A sliding plate 94 is slidably connected to the through groove 93. A limiting plate 95 is fixedly connected to the sliding plate 94. An elastic telescopic rod 910 is fixedly connected to the middle of the limiting plate 95. One end of the elastic telescopic rod 910 away from the middle of the limiting plate 95 is fixedly connected to the box cover 2. A sliding groove 99 is provided below the box cover 2. A correction plate is slidably connected to the sliding groove 99. 96. The side wall of the correction plate 96 is provided with a through groove 3 97. The through groove 3 97 is divided into two ends. The upper part of the through groove 3 97 penetrates the side wall of the correction plate 96, while the lower part of the through groove 3 97 does not penetrate the correction plate 96. Therefore, when the limiting plate 95 is located at the lower end of the through groove 3 97, it can limit the position of the two sets of correction plates 96. The through groove 3 97 is slidably connected to the sliding plate 94. A spring 98 is fixedly connected to the side wall of the correction plate 96. The end of the spring 98 away from the side wall of the correction plate 96 is fixedly connected to the side wall of the fixing plate 92.

[0028] Furthermore, an auxiliary plate 8 is fixedly connected to the bottom of the cooling box 1. By aligning the sliding plates 94 on both sides of the box cover 2 with the through groove 91 on the inner wall of the cooling box 1, when the sliding plate 94 touches the through groove 91, the sliding plate 94 will move upward along the through groove 93. The upward movement of the sliding plate 94 will drive the limiting plate 95 fixedly connected to it to move upward as well. Thus, the limiting plate 95 moves to the top of the through groove 97, at which point the position limit of the two sets of correction plates 96 can be released. Under the elastic reset action of the spring 98, the two sets of correction plates 96 will clamp and correct the steel plate on the auxiliary plate 8. The operation is simple and convenient.

[0029] In this invention, during use, the steel plate to be cooled is placed on the auxiliary plate 8 inside the cooling box 1. Then, the sliding plates 94 on both sides of the box cover 2 are aligned with the through groove 91 on the inner wall of the cooling box 1 and inserted. When the sliding plate 94 touches the through groove 91, the sliding plate 94 will move upward along the through groove 93. The upward movement of the sliding plate 94 will drive the limiting plate 95 fixedly connected to it to move upward as well, so that the limiting plate 95 moves to the top of the through groove 97. At this time, the position limitation of the two sets of correction plates 96 can be released. Under the elastic reset action of the spring 98, the two sets of correction plates will be driven to move upward. 96 clamps and corrects the steel plate on the auxiliary plate 8, and simultaneously installs and fixes the box cover 2 to the cooling box 1 with bolts. After the correction is completed, the screw 4 is rotated by turning the handle 3. The rotation of the screw 4 will drive the adjusting plate 5 to move, thereby covering the edge or non-edge of the steel plate. Then, cooling water can be input into the cooling box 1 through the water inlet pipe 6. There is no cooling water in the edge area between the adjusting plate 5 and the cooling box 1, which effectively reduces the waste of cooling water and cools the steel plate. At the same time, the small amount of cooling water leaking from the wear part of the adjusting plate 5 can be discharged through the water outlet pipe 7.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
