Description

Technical Field

[0001] The utility model relates to the field of aluminum coil processing equipment, in particular to a rapid cooling machine for annealing aluminum coils. Background Art

[0002] In aluminum processing and production, aluminum coil annealing is an indispensable process. After the aluminum coil comes out of the furnace, it needs to be forced cooled for 24 hours (in winter) to 32 hours (in summer) to cool it to within 100°C before it can enter subsequent processing.

[0003] At present, almost all forced cooling of annealed aluminum coils is done by fans. Even in winter, 24 hours of fan cooling is required to meet the needs of subsequent processes. Therefore, the current cooling method of annealed aluminum coils has the disadvantages of long cooling time, extended production cycle, affected production efficiency, and increased production costs. Utility Model Content

[0004] The utility model aims to provide an annealed aluminum coil rapid cooling machine to increase the cooling speed of the annealed aluminum coil, shorten the production cycle and improve the production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an annealing aluminum coil rapid cooling machine, comprising an aluminum coil support frame, an opening and closing cooling mechanism and a driving mechanism for driving the opening and closing cooling mechanism to perform opening and closing movements; the opening and closing cooling mechanism comprises a plurality of water-passing bodies, the plurality of water-passing bodies are all arc-shaped, the area enclosed by the plurality of water-passing bodies is a space for placing the aluminum coil, the interiors of the plurality of water-passing bodies are each provided with a water passage cavity, and the plurality of water-passing bodies are each provided with a water inlet end and a water outlet end.

[0006] The principles and advantages of this scheme are: the opening and closing cooling mechanism in this scheme can be opened and closed, and the movement of the water-passing body is driven by the driving mechanism to realize the opening and closing movement of the opening and closing cooling mechanism. When the water-passing bodies are away from each other, the opening of the opening and closing cooling mechanism is realized, and when the water-passing bodies are close to each other, the water-passing bodies of the opening and closing cooling mechanism are closed.

[0007] This scheme places the high-temperature annealed aluminum coil on the aluminum coil support frame, and the aluminum coil support frame supports the aluminum coil so that the aluminum coil is suspended in the air. During the process of placing the aluminum coil, the opening and closing cooling mechanism is in an open state, so that the aluminum coil can be placed on the aluminum coil support frame and erected. At this time, the aluminum coil is located between multiple water bodies. Then the driving mechanism is started, and the driving mechanism makes the multiple water bodies approach each other, and the multiple water bodies move to the outer side of the aluminum coil, and the water bodies are attached to the outer side of the aluminum coil, so that the multiple water bodies are combined together. Since the water bodies are arc-shaped, the arc-shaped water bodies are adapted to the outer arc surface of the aluminum coil, and the contact area between the water bodies and the aluminum coil is large. Then, cooling water is introduced into the water cavity through the water inlet end, and the cooling water flows in the water body and is discharged from the water outlet end. During the flow of the cooling water, the heat of the aluminum coil is taken away through heat exchange, so that the aluminum coil is quickly cooled down, and the annealed aluminum coil is quickly cooled.

[0008] The solution of the present application adopts a contact forced cooling method, in which circulating cooling water circulates in the water body, so that the cooling circulating water directly cools the annealed aluminum coil through the water body, greatly shortening the cooling time of the aluminum coil, overcoming the problem of long production cycle, improving production efficiency and saving production costs.

[0009] Preferably, as an improvement, the number of the water-through bodies is two, and the two water-through bodies are respectively located on the left and right sides of the aluminum coil support frame, and the two water-through bodies are arranged opposite to each other.

[0010] Therefore, the number of water bodies is set to two, the number of water bodies is set to be small, the positions of the water bodies are easy to arrange, and at the same time, there is no need to set too many driving mechanisms for driving the water bodies, and the structure of the entire cooler is relatively simple.

[0011] Preferably, as an improvement, the driving mechanism comprises a hydraulic station, the hydraulic station is provided with an oil cylinder, and the oil cylinder is provided with a piston for driving the water body to move.

[0012] Thus, the movement of the water body is driven by the extension and retraction of the piston of the oil cylinder of the hydraulic station, thereby realizing the opening and closing operation of the opening and closing type cooling mechanism.

[0013] Preferably, as an improvement, a bracket is connected between the piston and the water body, and the bracket is provided with a support part for connecting to the water body, and there are at least three support parts, one of which is coaxially arranged with the piston, and the other support parts are respectively located on both sides of the support part coaxially arranged with the piston.

[0014] Thus, the bracket is located between the piston and the water-passing body, and the bracket plays a role in connecting the piston and the water-passing body. The reason why the bracket is set in this scheme and the piston and the water-passing body are connected by the bracket is that if the bracket is not set, since the outer side of the water-passing body is arc-shaped, the end of the piston is directly connected to the water-passing body, and it is not easy to connect the end of the piston with the water-passing body, and the direct connection between the piston and the water-passing body is also a point connection, and the connection stability cannot be guaranteed. And through this scheme, the piston is connected to the bracket, and the part where the bracket is connected to the piston is set to a plane, which is more convenient for the piston to connect with the bracket than the piston is connected to the arc-shaped water-passing body. In addition, multiple support parts on the bracket are connected to the water-passing body, and multiple support parts are connected to the water-passing body at multiple points, so that the bracket can be stably connected to the outer side of the water-passing body, thereby improving the stability of the connection between the bracket and the water-passing body. Therefore, through this scheme, compared with the direct connection between the piston and the water-passing body, it is convenient to connect, and the connection stability is good at the same time.

[0015] Preferably, as an improvement, it also includes a base, and the aluminum coil support frame and the driving mechanism are fixedly located on the base. Thus, the arrangement of the base improves the stability of the cooling machine when placed on the ground.

[0016] Preferably, as an improvement, an arc-shaped support block is fixedly provided on the top of the aluminum coil support frame. An iron core is passed through the middle of the aluminum coil, and the arc-shaped support block is used to support the iron core on the aluminum coil. By placing the iron core of the aluminum coil on the support block, the aluminum coil is placed on the aluminum coil support frame.

[0017] Preferably, as an improvement, an elastic layer and a heat-conducting layer are provided on the side wall of the water-permeable body that is bonded to the aluminum coil, and the elastic layer is located between the heat-conducting layer and the water-permeable body.

[0018] Therefore, in this solution, when the water-permeable body is attached to the aluminum coil, due to the elasticity of the elastic layer, when the heat-conducting layer contacts the aluminum coil, the elastic layer is squeezed, and the elastic effect of the elastic layer makes the heat-conducting layer and the aluminum coil fit better, reducing the gap between the heat-conducting layer and the aluminum coil, ensuring the heat conduction effect. At the same time, the elastic layer also has a buffering effect. When the piston pushes the water-permeable body close to the aluminum coil, when the heat-conducting layer contacts the surface of the aluminum coil, the heat-conducting layer can squeeze the elastic layer and retreat to the side of the water-permeable body, avoiding hard contact between the heat-conducting layer and the aluminum coil.

[0019] Preferably, as an improvement, the heat conducting layer is an aluminum-copper composite material.

[0020] Preferably, as an improvement, the elastic layer is an accordion structure. Thus, the elastic layer of the accordion structure has a better buffering effect of the elastic layer, and the elastic layer of the accordion structure is not a solid structure, which can reduce the resistance of the elastic layer to heat transfer.

[0021] Preferably, as an improvement, the elastic layer is fur felt. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is further described in detail through specific implementation methods:

[0027] The figure marks in the drawings of the specification include: base 1, hydraulic station 2, bracket 3, first support part 31, second support part 32, third support part 33, water body 4, water outlet 5, aluminum coil 6, iron core 7, aluminum coil support frame 8, piston 9, water inlet 10, support block 11, heat conductive layer 12, elastic layer 13, side wall of water body 14, rivet 15.

[0028] Example 1

[0029] Basically as attached Figure 1-Figure 2 As shown: an annealing aluminum coil rapid cooling machine includes a base 1, an aluminum coil support frame 8, an opening and closing cooling mechanism and a driving mechanism for driving the opening and closing cooling mechanism to perform opening and closing movements.

[0030] The base 1 in this embodiment is placed horizontally on the ground, and two aluminum coil support frames 8 are provided. The two aluminum coil support frames 8 are arranged front and back, and the aluminum coil support frames 8 are both located in the middle of the base 1 in the horizontal direction. The bottom of the aluminum coil support frame 8 is fixedly connected to the base 1, and the specific fixing method can be fixed by bolts, for example. The aluminum coil support frame 8 is arranged vertically, and the top of the aluminum coil support frame 8 is fixed with an arc-shaped support block 11 (for example, welded or fixed by bolts), and the two ends of the support block 11 are tilted upward, and a horizontal iron core 7 is inserted in the middle of the aluminum coil 6. In this way, by placing the iron core 7 on the arc-shaped support block 11, the support blocks 11 on the two aluminum coil support frames 8 respectively support the two ends of the iron core 7, thereby realizing that the aluminum coil 6 is supported by the two aluminum coil support frames 8 and suspended in the air.

[0031] The opening and closing cooling mechanism in this embodiment includes a plurality of water bodies 4, and the plurality of water bodies 4 are distributed on the outside of the aluminum coil support frame 8, and the space between the plurality of water bodies 4 is a space for placing the aluminum coil. The plurality of water bodies 4 are all arc-shaped, and a water passage cavity is provided inside the plurality of water bodies 4. The outer wall of each water body 4 is fixed (for example, welded) with a 2 mm thick aluminum plate, and the water passage cavity is the internal space surrounded by the aluminum plate of the outer wall of the water body. The plurality of water bodies 4 are provided with a water inlet end 10 and a water outlet end 5, and the water inlet end 10 and the water outlet end 5 are both connected to the water passage cavity. Of course, in other embodiments, in order to improve the hardness and strength of the water body 4, the outer wall of the water body 4 can also replace the aluminum plate with a material with higher structural strength (for example, a carbon steel plate).

[0032] In this embodiment, two water bodies 4 are specifically used for explanation. There are two water bodies 4, which are respectively located on the left and right sides of the aluminum coil support frame 8 in the figure. The two water bodies 4 are both arc-shaped and arranged opposite to each other. The tops of the two water bodies 4 are provided with water outlets 5, and the bottoms of the two water bodies 4 are provided with water inlets 10. The water inlet 10 and the water outlet 5 are connected to the cooling tower through a water pipe.

[0033] There are two driving mechanisms in this embodiment, which are located on the left and right sides of the aluminum coil support frame 8. Both driving mechanisms include a hydraulic station 2, and a cylinder is provided in the hydraulic station 2. The cylinder is provided with a transverse piston 9 for driving the water body 4 to move. In this way, by controlling the cylinder, the piston 9 on the cylinder moves transversely, thereby realizing the left and right movement of the water body 4.

[0034] The end of the piston 9 can be directly connected to the outer wall of the water body 4 (for example, by welding). Of course, there is a more preferred connection method: in order to improve the stability of the connection between the piston 9 and the water body 4, a bracket 3 is connected between the piston 9 and the water body 4 in this embodiment. Figure 2As shown, the bracket 3 is in the shape of a Chinese character "shan" (mountain). The bracket 3 includes a vertical part and three horizontally arranged supporting parts. The three supporting parts are respectively a first supporting part 31, a second supporting part 32, and a third supporting part 33. The first supporting part 31, the second supporting part 32, and the third supporting part 33 are all horizontally arranged and are arranged in sequence from top to bottom. The vertical part is vertically arranged, and the vertical part, the first supporting part 31, the second supporting part 32, and the third supporting part 33 are integrally and fixedly connected. In this embodiment, the vertical part is a plane, and the vertical part is used to connect with the end of the piston 9, for example, fixed connection is carried out through a flange and bolts. Since the vertical part is a plane, it is convenient for the end of the piston 9 to be connected with the bracket. The second supporting part 32 is coaxially arranged with the piston 9. One end of the second supporting part 32 connected to the water passing body 4 is arc-shaped and has a larger volume than the other end, so that it can be stably connected to the outer wall of the water passing body 4. The first supporting part 31 and the third supporting part 33 are located on both sides of the second supporting part 32, so as to assist the second supporting part 32 in connecting with the water passing body 4, making the connection between the bracket 3 and the water passing body 4 more stable. In this embodiment, the connection mode between the ends of the first supporting part 31, the second supporting part 32, and the third supporting part 33 and the outer side surface of the water passing body 4 can be welding or fixed by bolts. Thus, in this embodiment, by setting the bracket 3, three supporting parts are provided on the bracket 3, and the three supporting parts are respectively connected to the outer side wall of the water passing body 4, thereby improving the connection stability between the water passing body 4 and the bracket 3. And the vertical part is a plane, and the connection between the vertical part and the end of the piston 9 is also convenient and stable. Thus, in this embodiment, the piston 9 drives the bracket 3 to move left and right, and the bracket 3 then drives the water passing body 4 to move left and right.

[0035] The specific implementation process is as follows: Initially, the two water passing bodies 4 are in a separated state (the opening and closing cooling mechanism is in an open state), for example Figure 1 the two water passing bodies 4 shown by the center dash line. The hot annealed aluminum coil 6 is placed between the two aluminum coil support frames 8, and the support blocks 11 on the two aluminum coil support frames 8 support the iron core 7, thus realizing that the aluminum coil 6 is suspended in the air.

[0036] Then the driving mechanism is started, the pistons 9 of the oil cylinders on the two hydraulic stations 2 extend outward, the two water bodies 4 approach each other, the water bodies 4 move from the dotted line position to the solid line position, the two water bodies 4 move to the outer side of the aluminum coil 6, the two water bodies 4 are combined, and the water bodies 4 are attached to the outer side of the aluminum coil 6, thereby realizing the merging of the opening and closing cooling mechanism. Since the water bodies 4 are arc-shaped, the arc-shaped water bodies 4 are adapted to the outer arc surface of the aluminum coil 6, so the contact area between the water bodies 4 and the outer wall of the aluminum coil 6 is large. At the same time, the cooling water in the cooling tower is passed into the water passage cavity in the water body 4 through the water inlet end 10, and the cooling water flows in the water passage cavity. The cooling water takes away the heat on the aluminum coil 6 through heat exchange, thereby realizing the forced cooling of the aluminum coil 6. After absorbing heat, the cooling water flows out through the water outlet end 5 and flows back to the cooling tower. The cooling tower cools the refluxed cooling water, and the cooled water enters the water body 4 again through the water inlet end 10 to continue cooling the aluminum coil 6. Therefore, through this embodiment, the cooling water continuously flows in the water body 4 , and takes away the heat of the aluminum coil 6 through heat exchange, thereby achieving rapid cooling of the aluminum coil 6 and rapid cooling of the annealed aluminum coil 6 .

[0037] The size of the water body 4 in this embodiment is determined by the size of the aluminum coil 6 to be cooled, the width of the water body 4 is the same as the width of the aluminum coil 6, and the inner wall diameter of the water body 4 is the same as the diameter of the aluminum coil 6. Therefore, the length and diameter of the water body 4 in this embodiment are not specifically limited here.

[0038] Comparison table of cooling time of annealed aluminum coils of the present invention and prior art

[0039]

[0040] It can be seen from this table that the cooling time of the cooling machine of the present application is greatly shortened compared with the prior art, which can speed up the circulation of annealed aluminum coils, shorten the production cycle, and save costs.

[0041] Example 2

[0042] This embodiment is further limited on the basis of embodiment 1, combined with Figure 3 and Figure 4 As shown, in this embodiment, an elastic layer 13 and a heat-conducting layer 12 are provided on the side wall where the water-permeable body 4 and the aluminum coil 6 are bonded, the elastic layer 13 is located between the heat-conducting layer 12 and the side wall 14 of the water-permeable body, the elastic layer 13 and the side wall 14 of the water-permeable body are fixed by riveting with multiple rivets 15, and the elastic layer 13 and the heat-conducting layer 12 are also fixed by riveting with multiple rivets 15.

[0043] The elastic layer 13 in this embodiment is made of a composite high-temperature resistant felt material, and the elastic layer 13 is an accordion structure (the accordion structure is a multi-layer corrugated structure similar to a bellows, and the middle part of the accordion structure is hollow), and the overall thickness of the multi-layer corrugations of the elastic layer 13 is 20 mm. The thermal conductive layer 12 in this embodiment is an aluminum-copper composite material, and the aluminum-copper composite material includes an aluminum layer and a copper layer, and the aluminum layer and the copper layer are composited, and the overall thickness of the thermal conductive layer 12 is 1 mm.

[0044] In this embodiment, when the water-permeable body 4 is attached to the aluminum coil 6, the elastic layer 13 is squeezed and shrinks to generate elastic force, and the elastic layer 13 plays a buffering role on the heat-conducting layer 12. At the same time, the elastic layer 13 is squeezed to generate elastic force, and the heat-conducting layer 12 has pressure under the elastic effect of the elastic layer 13, so that the heat-conducting layer 12 and the aluminum coil 6 are better attached, and the gap between the heat-conducting layer 12 and the aluminum coil 6 is reduced, so as to ensure the heat conduction effect.

[0045] In addition, the elastic layer 13 in this embodiment has a certain sealing effect on the riveted portion of the side wall of the water-passing body 4, thereby reducing or avoiding the leakage of cooling water from the riveted portion.

[0046] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
