Description

Technical Field

[0001] The utility model relates to the technical field of cooling and recycling steelmaking tailings, in particular to a steelmaking tailings cooling and recycling device. Background Art

[0002] Steelmaking involves melting pig iron in a furnace according to a specific process, adjusting the composition of the slag during steel and iron production to produce steel. Steelmaking requires controlling the carbon content (generally less than 2%), eliminating harmful elements such as phosphorus, sulfur, oxygen, and nitrogen, retaining or increasing beneficial elements such as silicon, manganese, nickel, and chromium, and adjusting the ratios of these elements to achieve optimal performance. Steel, as we commonly refer to, generally refers to steel rolled into various grades. Steel is a ferrous metal, but it is not completely equivalent to ferrous metals. Steel products include ingots, continuous casting billets, and various directly cast steel castings.

[0003] In the existing technology, steelmaking tailings usually need to be manually cleaned into a cooling pool using equipment for cooling treatment, and then the cooled tailings are taken out of the cooling pool for recycling. Since the steelmaking tailings do not have a good continuous cooling and recovery device, the cooling and recovery effect of the steelmaking tailings is reduced, labor is increased, and work efficiency is reduced.

[0004] In view of this, the present technical solution proposes a steelmaking tailings cooling and recovery device to better solve the above-mentioned problems. Utility Model Content

Water storage pipes are fixed on the inner sides of the fixing frame 1 and the fixing frame 2, and a nozzle is provided below the water storage pipes. An external water pipe is connected to the upper part of the interior of the fixing frame 1 and the fixing frame 2, and the lower part of the external water pipe is connected to the water storage pipe.

[0007] A feed pipe is connected to the right side of the cooling pool, and the left side of the feed pipe is inserted into the right side of the collecting trough. A screw conveyor is rotatably installed inside the feed pipe. A motor is fixed to the right side of the feed pipe, and the output end of the motor is connected to the screw conveyor. A water outlet hole is provided in a ring shape on the right side of the feed pipe inside the cooling pool, and a discharge port for discharging materials is provided at the lower right side of the feed pipe.

[0008] In a preferred embodiment, water level scale lines for controlling the height of cooling water are provided on the front and rear inner walls of the cooling pool.

[0009] In a preferred embodiment, a reinforcement platform for supporting the material induction bin is provided on the left side of the cooling pool and below the material induction bin, and a left support plate is fixed on the left side below the material induction bin.

[0010] In a preferred embodiment, the nozzles are linearly connected and arranged below the water storage pipe, and there are no less than six nozzles.

[0011] In a preferred embodiment, one end of the external water pipe away from the water storage pipe is connected to an external water pump.

[0012] In a preferred embodiment, the screw conveyor is composed of a rotating shaft and a spiral conveying blade, and the rotating shaft is connected to the conveying end of the motor.

[0013] In a preferred embodiment, a right support plate for supporting the material delivery pipe is fixed to the bottom of the material delivery pipe, and a collection box for receiving materials at the material outlet is placed on the right side of the right support plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: facilitating better continuous cooling and recycling of steelmaking tailings, saving manpower and increasing work efficiency.

[0015] 1. In the present invention, an appropriate amount of cooling water can be added to the interior of the cooling pool through the water level scale line so that the cooling water is located below the water outlet.

[0016] 2. In the utility model, the steelmaking tailings fall into the inner side of the feed bin through the discharge port of the steelmaking equipment. At this time, the steelmaking tailings slide into the inside of the cooling pool through the feed bin. When the steelmaking tailings pass through the nozzle, the nozzle can perform preliminary cooling treatment on the steelmaking tailings sliding down from the inner side of the feed bin. After the preliminary cooling treatment, the steelmaking tailings slide into the inside of the cooling pool and contact with the cooling water for further cooling treatment. In addition, a part of the steelmaking tailings falls into the aggregate trough through the tilting platform.

[0017] 3. In the present invention, by starting the motor, the motor drives the screw conveyor to rotate. At this time, the screw conveyor can transport the steelmaking tailings inside the collecting trough to the position of the discharge port. When water is transported inside the conveying pipe, the water will be discharged into the interior of the cooling pool through the water outlet. The transported steelmaking tailings fall into the interior of the collection box through the discharge port for recovery and storage. BRIEF DESCRIPTION OF THE DRAWINGS
