Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron and steel metallurgy technology, and more specifically, to an automatic explosion-proof safety device for a hot slag quenching tank. Background Technology
[0002] During the hot curing process of steel slag, water comes into contact with steel slag to generate hot steam. When the steam pressure is high, it may reach the explosion limit and cause an explosion accident, which poses a serious threat to production safety. Therefore, it is necessary to depressurize the hot curing tank of steel slag to prevent explosion.
[0003] Currently, among existing explosion-proof devices, such as the patent with authorization announcement number CN209128464U, this utility model discloses a safe and automatic explosion-proof device for a steel slag hot curing tank, relating to the field of steel slag hot curing treatment technology. This utility model includes a hot curing tank, with a balance tank connected to one side of the hot curing tank, a water tank connected to one side of the balance tank, and a detection device connected to the other side of the hot curing tank; a slag curing cover is movably connected to one surface of the hot curing tank; the balance tank includes a tank shell, with several sealing plates fixedly connected to the inner surface of the tank shell; the interior of the tank shell is divided from top to bottom into a first balance chamber, a second balance chamber, and a water storage tank via the several sealing plates.
[0004] However, it was found during the use of the device that the depressurization process was rather complicated, which reduced the ease of use. Summary of the Invention
[0005] To address the aforementioned technical problems, an automatic explosion-proof safety device for steel slag hot curing tanks is provided, which improves the explosion-proof effect of the tank, enhances the safety of the steel slag hot curing tank, improves the water recycling effect, and reduces energy consumption.
[0006] The technical means adopted in this utility model are as follows:
[0007] An automatic explosion-proof safety device for a steel slag hot curing tank includes: a tank body, a discharge pipe, and multiple sets of nozzles. The discharge pipe is installed on the upper part of the inner side wall of the tank body, and the multiple sets of nozzles are all connected to the discharge pipe. It also includes a recovery device, a pressure relief device, a first conveying pipe, and a second conveying pipe. The output end of the first conveying pipe is connected to the discharge pipe, and the input end of the first conveying pipe is connected to the recovery device, which is used to recover condensate. The input end of the second conveying pipe is connected to the tank body, and the output end of the second conveying pipe is connected to the pressure relief device, which is used to relieve pressure within the tank body and to condense steam. Steel slag is placed inside the tank body for storage. The system stores water, which is then transported to the first conveying pipe via a recycling device. This first conveying pipe then transports the water to the discharge pipe, allowing multiple nozzles to spray the water into the pool. When the steel slag comes into contact with the water, it generates a large amount of steam, increasing the pressure inside the pool. Once the pressure reaches a set level, the excess pressure inside the pool is automatically discharged through the second conveying pipe and a pressure relief device. This improves the explosion-proof effect of the pool and enhances the safety of the steel slag hot quenching pool. As the pressure in the pool is released, the steam is also released. The steam is condensed through the pressure relief device, and the condensate is then transported to the recycling device, improving the water recycling effect and reducing energy consumption.
[0008] Preferably, the pressure relief device includes a cooling device, a collection tank, a pressure tank, a sealing ring, a sealing plug, multiple sets of telescopic rods, multiple sets of springs, and a third conveying pipe. The top of the collection tank is connected to the bottom of the pressure tank, and the bottom of the pressure tank is provided with multiple sets of through holes. The sealing ring is installed on the inner wall of the pressure tank. The output end of the second conveying pipe is connected to the top of the pressure tank. The sealing plug is installed on the top of the multiple sets of telescopic rods. The multiple sets of telescopic rods are all installed on the inner wall of the pressure tank. The multiple sets of springs are respectively fitted onto the multiple sets of telescopic rods. The input end of the third conveying pipe is connected to the pressure tank, and the output end of the third conveying pipe is connected to the cooling device. The device is connected to the cooling device, which is used to cool the steam. The second conveying pipe transports the pressure and steam in the pool to the pressure tank. The pressure pushes the sealing plug downward, so that the air pressure and steam are transported to the cooling device through the third conveying pipe. The cooling device discharges the pressure and cools the steam. Multiple sets of springs provide upward elastic support to the sealing plug, which helps to maintain a certain pressure in the pool and improves the heat treatment effect on the steel slag. The condensate generated in the pressure tank flows to the collection tank through the through hole, which improves the convenience of condensate collection in the pressure tank.
[0009] Preferably, the cooling device includes a cooling box, two sets of conveying boxes, multiple sets of hot air pipes, an exhaust pipe, and a fourth conveying pipe. The two sets of conveying boxes are installed inside the cooling box. The multiple sets of hot air pipes are all connected and arranged between the two sets of conveying boxes. The exhaust pipe and the input end of the fourth conveying pipe are both connected to the lower conveying box. The output end of the fourth conveying pipe is connected to the recovery device. The output end of the third conveying pipe is connected to the upper conveying box. A cooling medium is provided inside the cooling box. The third conveying pipe conveys steam and pressure to the upper conveying box. The steam and pressure are conveyed to the lower conveying box through the multiple sets of hot air pipes. The pressure is discharged outward through the exhaust pipe. The cooling medium cools down the multiple sets of hot air pipes, causing the steam to condense in the multiple sets of hot air pipes. The condensed water falls into the lower conveying box and is conveyed to the recovery device through the fourth conveying pipe.
[0010] Preferably, the recycling device includes a collection box and a first pump body, the output end of the fourth conveying pipe is connected to the first pump body, and the first pump body is connected to the collection box; the first pump body extracts condensate from the first conveying pipe through the fourth conveying pipe, so that the condensate is stored inside the collection box.
[0011] Preferably, it also includes a second pump body, which is connected to the collection tank and the output end of the second pump body is connected to the first conveying pipe; the second pump body extracts the condensate in the collection tank and the extracted condensate is transported to the inside of the pool through the first conveying pipe, thereby improving the convenience of condensate recycling.
[0012] Preferably, it also includes an air-cooled cooling component, which is connected to and installed on the cooling box; the air-cooled cooling component circulates and cools the cooling medium in the cooling box, thereby improving the condensation effect of the steam.
[0013] Preferably, the exhaust pipe outlet end is provided with a protective cover; this improves the protection effect of the exhaust pipe outlet end.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: steel slag is placed inside the pool for storage, and water is transported to the first conveying pipe through a recycling device. The first conveying pipe then transports the water to the discharge pipe, thereby allowing multiple sets of nozzles to spray water into the pool. When the steel slag comes into contact with the water, it generates a large amount of steam, which increases the pressure inside the pool. When the pressure reaches a set height, the excess pressure inside the pool is automatically discharged through the second conveying pipe and the pressure relief device, thereby improving the explosion-proof effect of the pool and the safety of the steel slag hot quenching pool. At the same time as the pressure in the pool is released, the steam is also released. The steam is condensed through the pressure relief device, and the condensate is then transported to the recycling device, improving the water recycling effect and reducing energy consumption.
