Abstract
Description
Technical Field
[0001] This application relates to the field of deep well casting technology, and specifically discloses a cofferdam isolation structure for deep well casting. Background Technology
[0002] A casting furnace is a device specifically designed for producing metals or alloys. It typically consists of one or more furnaces that heat molten metal or alloys and pour them into a cavity to form the desired shape and size during the cooling process.
[0003] When casting furnaces are in use, slag accumulates in the furnace holes. During the casting process, the high temperature melts and breaks off the slag, causing molten aluminum to overflow. If the overflowing molten aluminum cannot be dealt with in time, it may lead to production accidents. Therefore, it is necessary to use a dike isolation structure.
[0004] Existing cofferdam structures are cast onto the installation surface, and the formed cofferdam structure prevents the overflow of molten aluminum and avoids the possibility of the overflowing aluminum encountering circulating water. However, the above-mentioned cofferdam structure can only prevent the overflowing aluminum from encountering circulating water on the same plane. In actual use, because the overall height of the cofferdam structure is limited, the circulating water of the casting machine may come into contact with the molten aluminum when splashed, which may lead to accidents such as explosion or high temperature fire of the equipment.
[0005] This invention provides a cofferdam isolation structure for deep well casting to solve the above-mentioned problems. Utility Model Content
[0006] The purpose of this invention is to solve the problem that the height of traditional cofferdam structures cannot be changed, and they cannot isolate the splashed circulating water.
[0007] To achieve the above objectives, the basic solution of this utility model provides a cofferdam isolation structure for deep well casting, including a cofferdam structure cast on the mounting surface, and functional components set at each corner inside the cofferdam structure. The cofferdam structure has a plurality of rectangular receiving chambers formed inside, and a plurality of rectangular annular grooves arranged around the receiving chambers are vertically opened downward on the top surface of the cofferdam structure. The top of the cofferdam structure is provided with a plurality of rectangular baffles that can be inserted into the rectangular annular grooves respectively.
[0008] Furthermore, the inner side of each rectangular baffle is provided with a bottom enclosure that extends into the receiving chamber and fits tightly against the bottom surface of the receiving chamber. A bent portion that bends and fits the cofferdam structure is fixed between the rectangular baffle and the bottom enclosure. An inclined fitting portion is formed between the ends of adjacent bottom enclosures.
[0009] Furthermore, each of the inclined fitting portions is fixedly connected to a vertical baffle that fits the bending portion, and adjacent vertical baffles are combined to form a mounting groove for installing functional components. Each of the adjacent vertical baffles also has a liquid inlet at its bottom.
[0010] Furthermore, the liquid inlet is fitted to the top surface of the inclined fitting portion.
[0011] Furthermore, a stop plate that fits against the top surface of the cofferdam structure is also fixedly connected to the rectangular baffle.
[0012] Furthermore, a vertical height-increasing panel can be detachably connected to the rectangular baffle.
[0013] Furthermore, the rectangular baffle has several vertical mounting slots, and the bottom of the vertical height-increasing panel is fixed with several vertical mounting plates that can be respectively installed into the vertical mounting slots. Connectors are provided between the vertical mounting plates and the vertical mounting slots.
[0014] The principle and effect of this solution are as follows:
[0015] 1. Compared with the prior art, this utility model can prevent the overflow of molten aluminum by casting a cofferdam structure, and can also prevent the overflow of circulating water from meeting and exploding with molten aluminum. It can ensure that circulating water and molten aluminum will not meet in the plane. At the same time, by setting rectangular baffles and vertically raised guardrails installed in the direction of possible circulating water splashing, it can prevent splashed circulating water from entering the cofferdam structure, thus solving the problem that the height of traditional cofferdam structures cannot be changed and cannot isolate splashed circulating water.
[0016] 2. Compared with the prior art, after the aluminum liquid solidifies, the present invention can directly open a notch in the solidified aluminum block by pulling out the rectangular baffle, which facilitates the cleaning of the solidified aluminum block. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0021] The reference numerals in the accompanying drawings include: 1. cofferdam structure; 2. stop plate; 3. rectangular baffle; 4. bend; 5. bottom enclosure; 6. vertical baffle; 7. vertical heightening guardrail; 8. sealing and fitting part.
[0022] A cofferdam isolation structure for deep well casting, implementing, for example Figure 1 As shown:
[0023] It includes the cofferdam structure 1, which is cast onto the mounting surface, and the functional components installed at each corner inside the cofferdam structure 1.
[0024] The cofferdam structure 1 has several rectangular accommodating chambers formed inside, through which the casting furnace is placed, and the cofferdam structure 1 is set up perpendicularly to the installation surface.
[0025] In this embodiment, the top surface of the cofferdam structure 1 is vertically opened with several rectangular annular grooves arranged around the receiving chamber, and several rectangular baffles 3 that can be inserted into the rectangular annular grooves are installed on the top of the cofferdam structure 1. Specifically, the bottom of the rectangular baffle 3 is formed with a sealing fitting part 8 that can be sealed and inserted into the rectangular annular groove. The ends of adjacent rectangular baffles 3 and sealing fitting parts 8 are inclined so that they can fit together.
[0026] Furthermore, a bottom retaining wall 5 is provided inside each rectangular baffle 3. The bottom retaining wall 5 extends into the receiving chamber and fits tightly against the bottom surface of the receiving chamber. A bent portion 4, which is bent and fits against the cofferdam structure 1, is welded between the rectangular baffle 3 and the bottom retaining wall 5. An inclined fitting portion is formed between the ends of adjacent bottom retaining walls 5. With this structural arrangement, after the aluminum liquid solidifies, the bottom retaining wall 5 can be lifted by pulling up the rectangular baffle 3 to open a notch in the solidified aluminum block, facilitating the cleaning of the solidified aluminum block.
[0027] like Figure 1 and Figure 2 As shown, each inclined fitting part is also welded with a vertical baffle 6 that fits the bent part 4. Each adjacent vertical baffle 6 has a liquid inlet at its bottom, which fits against the top surface of the inclined fitting part. Adjacent vertical baffles 6 form a mounting groove for installing a functional component to seal the liquid inlet. In this embodiment, the functional component is a functional plate that can seal the liquid inlet. By opening the functional plate, when the overflowing aluminum liquid solidifies on the top surface but not inside, the undiluted aluminum liquid enters the inside of the vertical baffle 6 through the liquid inlet, facilitating extraction. After extraction, the functional plate is reinstalled to seal the liquid inlet.
[0028] In this embodiment, a stop plate 2 that fits against the top surface of the cofferdam structure 1 is also welded onto each rectangular baffle 3 to increase the stability of the rectangular baffle 3.
[0029] Simultaneously, a vertical height-increasing panel 7 can be installed on the rectangular baffle 3. Specifically, each rectangular baffle 3 has two vertical mounting slots, and each vertical height-increasing panel 7 has two vertical mounting plates welded to its bottom. The vertical mounting plates can be inserted into the corresponding vertical mounting slots, and connectors are installed between the vertical mounting plates and the vertical mounting slots. The connectors are bolts, and internal threaded holes for screwing in the bolts are provided at the positions of the vertical mounting plates and the corresponding vertical mounting slots.
[0030] When this utility model is used, the cast cofferdam structure 1 can prevent the overflow of aluminum liquid that occurs during the deep well casting process, and can also prevent the explosion caused by the overflow of circulating water meeting the aluminum liquid. It can ensure that the circulating water and aluminum liquid will not meet in the plane, thus achieving isolation between the overflowing aluminum liquid and the circulating water.
[0031] Meanwhile, the rectangular baffle 3 and the vertically raised baffle 7 installed to target the possible direction of circulating water splash can prevent the splashed circulating water from entering the cofferdam structure 1.
[0032] Furthermore, once the molten aluminum has solidified, the rectangular baffle 3 can be pulled out directly to create a notch in the solidified aluminum block, facilitating its cleaning.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
