The upper end of the draft tube 20 is immersed in the quench media. The quenching tank body 10 and the guide cylinder 20 are both cylindrical. The pushing device 30 is used for pushing the quenching medium to circularly flow. The quenching apparatus 100 is provided with a plurality of pushing devices 30. The draft tube 20 defines a central axis 201. A plurality of pushing devices 30 are evenly distributed along the circumference of the central axis 201. Specifically, the number of the pushing devices 30 is 6. The flow dividing device 40 is used for dividing the quenching medium guided by the draft tube 31. The flow rate of the quench medium in the quench zone can be adjusted by means of the pushing device 30.
The pushing device 30 includes: a draft tube 31, a propeller 32 and a motor. The draft tube 31 serves to guide the flow of the quenching medium.
The propeller 32 is used to drive the quench medium to flow in the draft tube 31. The motor drives the propeller 32 to rotate. Specifically, a motor level variable frequency motor. Propeller 32 is a three-bladed propeller.
The draft tube 31 includes: an inlet pipe section 311, an outlet pipe section 312, and a connecting pipe section 313. The inlet pipe section 311 is formed with an inlet for the quench medium to enter the draft tube 31. Specifically, one end of inlet tube section 311 is tapered or flared. The tapered or flared entrance to the draft tube 31 facilitates the introduction of quench medium into the draft tube 31.
The propeller 32 is provided at the inlet. The inlet tube section 311 extends in a vertical direction. The inlet tube section 311 extends in a direction parallel to the central axis 201. A connecting pipe section 313 connects the inlet pipe section 311 and the outlet pipe section 312. The connecting pipe section 313 extends in the horizontal direction. The outlet tube section 312 extends obliquely upwards at an angle to the horizontal. The outlet pipe section 312 extends obliquely across the central axis 201. The outlet pipe section 312 is formed with an outlet for the quench medium to exit from the draft tube 31. The outlet is disposed in the draft tube 20.
The flow dividing device 40 includes: the pipeline splitter plate 41, the first cylinder-type splitter plate 421, the second cylinder-type splitter plate 422 and the circumferential splitter plate 43.
