Description

Technical Field

[0001] The utility model is applicable to the technical field of steel smelting, and particularly relates to an energy-saving treatment device for hot slag in steel smelting. Background Art

[0002] At present, a large amount of hot slag is produced in the process of steel smelting. If the hot slag is discharged directly, it will not only pollute the surrounding environment, but also endanger the safety of people around, and cause a waste of heat energy. Therefore, it is often necessary to use corresponding heat recovery mechanisms to recover the heat energy inside the hot slag.

[0003] However, when recycling heat energy nowadays, water is often used to absorb the heat to achieve heat recovery. In the process of using water to absorb heat, due to the limitation of the water used for absorbing heat during transportation, only part of the water that is in contact with the outer wall of the tank storing the hot slag can absorb heat, while other liquids that cannot be in contact cannot absorb heat, thus affecting the overall waste heat utilization and recovery efficiency. Therefore, we propose an energy-saving treatment device for hot slag from steel smelting. Utility Model Content

[0004] The main purpose of the utility model is to provide an energy-saving treatment device for hot slag in steel smelting, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An energy-saving treatment device for hot slag in steel smelting, comprising a heat preservation tank, support rods are fixedly installed on the four side surfaces of the inner bottom of the heat preservation tank, and a storage tank is fixedly installed between the top ends of the support rods;

[0007] A connecting block is fixedly installed on the outer surface of the storage tank, and the number of the connecting blocks is several groups. A fixed sleeve is fixedly installed on the outer top surface of each connecting block. A circulation pipe is fixedly installed between the inner sides of every two groups of the fixed sleeves, and the circulation pipe is located between the outer side of the insulation tank and the inner side of the storage tank. A connecting pipe is fixedly connected between the bottoms of every two groups of the circulation pipes, and the connecting pipe is located on the outer side of the storage tank.

[0008] Both ends of the circulation pipe are fixedly connected with a liquid inlet pipe, and the liquid inlet pipe passes through and is fixedly installed inside the side of the insulation tank. A fixed bracket is fixedly installed on the middle end surface of the outer side of the insulation tank, and a circulation pump is fixedly installed on the outer surface of the fixed bracket.

[0009] By adopting the above technical solution, through the connection of the circulation pipe and the connecting pipe, and the operation connection of the circulation pump, the heat-absorbing liquid can circulate outside the storage tank, so that the heat-absorbing liquid can absorb the heat dissipated by the hot slag inside the storage tank during the flow, thereby ensuring that the heat-absorbing liquid at different positions can absorb heat, thereby improving the absorption and recovery efficiency of heat energy by the heat-absorbing liquid.

[0010] As an optional solution of the technical solution of the present application, each of the outer top surfaces of the liquid inlet pipes is fixedly connected to a connecting elbow, each of the outer tops of the connecting elbows is fixedly connected to a fixed pipe, and the tops of the side edges of the two groups of fixed pipes are respectively connected to the liquid inlet and the liquid discharge port of the circulation pump.

[0011] By adopting the above technical solution, the operation of the circulation pump is ensured by connecting the fixed pipe and the connecting elbow, so as to drive the heat-absorbing liquid to be circulated and transported.

[0012] As an optional solution of the technical solution of the present application, a discharge pipe is fixedly connected to the middle end of the bottom of the storage tank, and a solenoid valve is fixedly installed on the bottom surface of the discharge pipe, and the solenoid valve is located on the outer side of the bottom of the insulation tank.

[0013] By adopting the above technical solution, the control of opening and closing of the discharge pipe is realized through the structural function of the electromagnetic valve.

[0014] As an optional solution of the technical solution of the present application, a control valve is fixedly installed on the outer surface of each connecting elbow, and the control valve is located on the outer surface of the insulation tank.

[0015] By adopting the above technical solution, the control processing of the connecting elbow is realized through the structural function of the control valve.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is an energy-saving treatment device for hot slag in steel smelting. The circulation pipe wound around the outside of the insulation tank is connected for use through a connecting pipe, and the circulation pipe and the circulation pump are connected for use by connecting the elbow pipe, the liquid inlet pipe and the liquid discharge pipe. Therefore, during the operation of the circulation pump, the heat-absorbing liquid can circulate outside the storage tank, so that the heat-absorbing liquid can absorb and process the heat dissipated by the hot slag inside the storage tank during the flow, thereby ensuring that the heat-absorbing liquid at different positions can absorb heat, thereby improving the absorption and recovery efficiency of the heat-absorbing liquid for heat energy.

The technical solution of the present application is an energy-saving treatment device for hot slag in steel smelting, which is equipped with a control valve and a solenoid valve on the outside of a discharge pipe and a connecting elbow, respectively.
