Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to a steel smelting quenching device. Background Art

[0002] Iron and steel smelting is a general term for the metallurgical process of steel and iron. Most modern ironmaking uses blast furnace ironmaking. However, when the workpiece is quenched in the quenching tank, carbon black and oxide scale will be produced and settle to the bottom end surface of the quenching tank. After long-term deposition, some carbon black and oxide scale will harden into blocks and adhere to the bottom surface of the quenching tank, which is very troublesome to clean.

[0003] According to Chinese patent CN 219342207 U, a steel smelting quenching device is disclosed, including a quenching pool, an electromechanical box is fixedly installed on the left side of the quenching pool, a motor is installed on the inner bottom wall of the electromechanical box, and two rectangular grooves are provided on the inner wall of the quenching pool, and a first bearing is embedded in the inner bottom wall of one of the two rectangular grooves, a threaded rod is fixedly connected to the inner ring of the first bearing, and a second bearing is embedded on the upper surface of the electromechanical box. This device arranges a filter plate inside the quenching pool, and the filter plate can move up and down in the quenching pool driven by the motor, so that impurities generated in the quenching pool can be filtered out, and a cleaning plate is arranged at the rear of the quenching pool, and the cleaning plate can clean up the impurities on the filter plate, effectively preventing the impurities in the quenching pool from accumulating at the bottom of the quenching pool, which is inconvenient for later cleaning, thereby improving the processing quality of the workpiece and saving the working time of the staff;

[0004] Although this patent can achieve the effect of cleaning the filter plate by raising the filter plate, since the impurities attached to the filter plate are cleaned directly after the filter plate is raised, it is easy for fine impurities to fall into the quenching tank again through the holes on the filter plate, which not only makes the subsequent cleaning work more cumbersome, but also makes the cleaning operation more troublesome.

[0005] Therefore, it is necessary to provide a new steel smelting quenching device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a steel smelting and quenching device.

[0008] A fixed assembly is installed inside the quenching box, comprising a fixed cylinder installed in the quenching box, and an extraction assembly for extracting water in the quenching box is installed on the outer wall of the fixed cylinder;

[0009] The filter assembly is installed on the inner side of the fixed cylinder, and includes a rotating rod rotatably connected to the inner side of the quenching box through a sealed bearing, a filter barrel is fixed on the top of the rotating rod, and first filter holes are equidistantly opened on the outer wall of the filter barrel, and the filter barrel is rotatably connected to the inner side of the fixed cylinder;

[0010] The driving assembly is installed at the bottom of the rotating rod and is used to drive the rotating rod to rotate.

[0011] Preferably, the extraction assembly includes a water inlet pipe fixed to the outer wall of the fixed cylinder, a water outlet pipe is fixed to the side of the fixed cylinder corresponding to the water inlet pipe, a water pump is installed on the top of the water outlet pipe, and filter screens are fixed on the inner sides of the water inlet pipe and the water outlet pipe.

[0012] Preferably, the driving assembly comprises a support frame fixed to the bottom of the quenching box, a motor is fixed on the inner side of the support frame, and an output end of the motor is fixed to one end of a rotating rod.

[0013] Preferably, a slide groove is provided on the top of the fixing cylinder, a cover plate is slidably connected to the inner side of the slide groove, a handle is fixed on the top of the cover plate, and an anti-slip ring is fixed on the outer wall of the handle.

[0015] Preferably, the outer wall of the filter screen is provided with second filter holes at equal intervals, and the diameter of the second filter holes is larger than the diameter of the first filter holes.

[0016] Compared with the related art, the steel smelting and quenching device provided by the utility model has the following beneficial effects:
