Export even partition.
In the present invention：The inner wall of inside groove is big in small two end section in intermediate cross-section, the throat tubular construction formed by cambered surface.
The advantage of the invention is that：Since quenching tank body includes outer groove and inside groove, it is less than outer groove, inside groove at the top of inside groove
Top is dipped in hardening media, wherein inside groove be cylindricality groove body, inside groove periphery be at least arranged three it is equally distributed to hardening media
The device of agitation, agitating device include diversion pipe, and the entrance of diversion pipe is motor-driven less than being equipped at the top of inside groove, in diversion pipe
The outlet of blade, diversion pipe can enter inside groove cycle pair with the hardening media in outer groove positioned at the side wall of inside groove bottom by bottom
Workpiece radiates, the speed that can be circulated according to adjusting is sought especially under the control of variable-frequency motor.Due in interior trench bottom
At least provided with three annular drainage hoods, each annular drainage hood contains the upward drainage of the horizontal drainage plate and annular of annular
Plate, horizontal drainage plate are a horn mouth outside rectangle with the annular outlet that drainage plate passes through arc-shaped transition, especially diversion pipe upwards,
Diversion pipe sets that there are two upright by outside rectangle horn mouth and inside groove bottom sidewall slitless connection, outside rectangle in horn mouth
In the splitterr vanes of eight word arrangements, they will export even partition, these measures would be even more beneficial to that the quenching into inside groove is made to be situated between
Matter is evenly distributed in an opposite plane of inside groove bottom.Since upward drainage plate is arranged concentrically in each drainage hood, and by slot
Body bottom, which has, is divided into corresponding annular groove, their top is located in same level, and especially their top is not higher than interior
The a quarter of groove height, it can be ensured that have sufficiently large workspace in inside groove.Since the inner wall of inside groove is small by two in intermediate cross-section
End section is big, the throat tubular construction formed by cambered surface, can make to accelerate by the flow velocity of hard heat treatment medium.
Structure of the invention is compact, easy to maintain.
