Description

Technical Field

[0001] The present application relates to the technical field of aluminum rod production, and in particular to a crystallizer aluminum leakage detection device. Background Art

[0002] In the field of metallurgical industry, crystallizers are often used for casting aluminum liquid. Crystallizers are equipment that receives aluminum liquid and solidifies it into aluminum ingots of a set shape according to a specified cross-sectional shape. The most commonly used is an oil-gas lubricated round rod crystallizer. In the aluminum rod forming process, the molten metal is first melted in a smelting furnace and quickly transferred to a diversion trough. When the temperature reaches the pouring temperature, the molten metal is allowed to flow into the crystallizer. The liquid metal melt contacts the bottom ingot head and the graphite ring on the inner wall of the crystallizer to form a solidified shell. Due to solidification shrinkage, the metal gradually separates from the graphite ring on the inner wall of the crystallizer to form a gap. As the ingot head moves downward at a certain speed, the ingot contacts the cooling water sprayed from the lower end of the crystallizer. Under the secondary cooling effect of the cooling water, the entire ingot gradually solidifies.

[0003] Crystallizer in related art, such as Figure 1 and Figure 2 As shown, it generally includes a cooling water pool 1 and a horizontal plate 2 bolted to the top of the cooling water pool 1; a plurality of aluminum liquid channels 21 are opened on the top of the horizontal plate 2, and a plurality of tapered openings 22 are opened on both sides of the aluminum liquid channel 21, and a perforation 23 is opened at the bottom of each tapered opening 22, and the bottom of the perforation 23 is connected to the cooling water pool 1; an annular cooling water pipe 24 is installed at the bottom of the horizontal plate 2 below the perforation 23, and a plurality of injection holes 241 are opened in sequence along the circumference of the inner circumference of the cooling water pipe 24, and a high-pressure liquid supply pipe 25 is connected to the outer circumference of the cooling water pipe 24. Working principle: first, the hot molten aluminum liquid is injected into the aluminum liquid channel 21, and then the aluminum liquid in the aluminum liquid channel 21 flows toward the cooling water pool 1 through the perforation 23. When the aluminum liquid flows from the perforation 23 to the lower side, condensate will be sprayed from the injection hole 241, and the liquid aluminum liquid will slowly solidify from the outside, and then the aluminum rod will be initially formed, and the initially formed aluminum rod will then enter the cooling water pool 1 for cooling and forming.

[0004] When the aluminum liquid flows downward through the tapered mouth 22, if there is a problem with the condensate sprayed from the injection hole 241, or other problems cause leakage of the aluminum rod during the initial solidification process (not solidified well), then because it is a tooling, the aluminum liquid in the aluminum liquid channel 21 will continue to flow from the damaged part of the initially formed aluminum rod into the condensate, and a large amount of aluminum liquid flowing in can easily cause an explosion; however, when the above-mentioned crystallizer leaks, it is inconvenient to detect the leakage in time, which will pose a greater safety risk.

When the first slider 621 drives the second plug board 62 to be inserted into the second slot 431 under the action of the fixing spring 622, at this time the second plug board 62 drives the first abutting block 95 to move, and then the first abutting block 95 drives the second abutting block 96 to move under the action of the inclined surface 97, the movement of the second abutting block 96 drives the horizontal rod 92 to move, at this time the horizontal rod 92 drives the horizontal tube 91 to rotate under the action of the spiral block 921 and the spiral groove 911, the rotation of the horizontal tube 91 drives the gear 93 to rotate, the rotation of the gear 93 drives the rack 94 to move towards the direction close to the fourth slot 541, and the movement of the rack 94 towards the direction close to the fourth slot 541 drives the fourth plug board 82 to move towards the direction close to the fourth slot 541, so that the fourth plug board 82 can be driven to move; in summary, the provided driving component 9 facilitates the driving of the fourth plug board 82 to move.

[0049] Reference Figures 5-6, a connecting block 511 is vertically fixed on the pressure sensor 51, and the side of the third slider 75 away from the electric push rod 72 can abut against the side of the connecting block 511 close to the third plug board 54. With the arranged connecting block 511, when the push board 73 is driven by the electric push rod 72 to move out of the third through hole 71 to release the limit on the first plug board 43 and the third plug board 54, and then the push board 73 is continuously driven by the electric push rod 72 to move out of the third through hole 71, the movement of the push board 73 out of the third through hole 71 can make the connecting block 511 move out of the third slot 44, and the movement of the connecting block 511 out of the third slot 44 drives the third plug board 54 to move out of the third slot 44. In this way, when the third plug board 54 is adhered to the inner wall of the third slot 44, it is convenient to loosen the third plug board 54, so as to facilitate the removal of the pressure sensor 51.

[0050] Working principle: If there is a liquid leakage phenomenon during the preliminary curing process of the aluminum rod, the molten aluminum liquid at this time will melt the annular hose 41, so that the annular hose 41 will leak air; when the annular hose 41 leaks air, the pressure sensor 51 can detect it at this time, and send the collected pressure information to the central receiver module through the wireless transmitter, and then the system will automatically alarm through the terminal and display the state of the annular hose 41, so that the liquid leakage situation can be detected in time; in summary, by adopting the above scheme, it is convenient to detect the liquid leakage situation in time, so as to reduce the safety risk.

[0051] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
