the flow direction of the quenching medium can be controlled by adjusting the angle of the guide plate according to the requirement, the guide plate is adjusted to the horizontal direction, the width of the cooling medium outlet can be reduced, the cooling medium is in a turbulent state, the flow is reduced, the pressure is increased, the cold and hot mediums can be fully mixed, the guide plate is adjusted to the vertical direction, the width of the cooling medium outlet can be increased, the flow of the cooling medium is increased, the pressure is reduced, and the cooling capacity is improved; surrounding plates are arranged on the upper part of the medium outlet and the periphery of the lower part of the quenching table, so that the cooling medium is outwards diffused from the upper part of the workpiece, the cooling medium is prevented from being diffused everywhere, and the cooling capacity of the cooling medium is effectively improved; the medium blowing system is arranged above the carrier roller between the quenching table and the circulating pump, and comprises a fan and a fan cover, the fan cover concentrates wind power on the surface of a workpiece, strong wind generated by the fan blows off cooling medium on the surface of the workpiece, the blown cooling medium drops into the quenching tank, the cooling medium is saved, and the workload of a subsequent cleaning procedure is reduced.
2. The circulating water-cooled intelligent quench tank of claim 1, wherein: the specific working process is as follows: the workpiece is placed in the charging basket, the charging basket is placed on the carrier roller, and the carrier roller is driven to rotate by power, so that the charging basket filled with the workpiece can move on the carrier roller, the charging basket and the workpiece are heated and kept at a certain temperature and time in the heating furnace, then move out of the heating and keeping temperature area and move onto the carrier roller in the cooling area, the carrier roller in the cooling area is controlled by the outside to stop rotating, the quenching platform lifting system controls the quenching platform to descend, the charging basket and the workpiece are immersed into a cooling medium along with the quenching platform, and in the process of moving up and down of the quenching platform, the workpiece and the cooling medium can generate rapid relative motion, the steam around the workpiece is eliminated by using the cooling medium, the steam is rapidly diffused, and the workpiece is uniformly cooled; in the process of cooling the workpiece, the circulating pump rotates, high-temperature cooling medium is sucked through the liquid suction pipeline and the liquid suction port, heat exchange is carried out through the cooler of the liquid outlet pipeline, the temperature of the high-temperature cooling medium is reduced, and the low-temperature cooling medium flows to the workpiece from the medium outlet to cool the workpiece; the cooled workpiece is lifted by the lifting system of the quenching table, is separated from the cooling medium, reaches the position horizontal to the carrier roller in the heating furnace, the carrier roller rotates, the workpiece is translated to the lower part of the fan housing of the medium blowing system, the fan housing concentrates wind power on the surface of the workpiece, the fan blows off the cooling medium on the surface of the workpiece, the blown cooling medium drops into the quenching tank, and the blown-off workpiece moves to a subsequent station through the rotation of the carrier roller.
