Strong loop quick cooling chamber

Abstract

The invention relates to a strong loop quick cooling chamber, comprising a wind cooling chamber which is composed by a outer shell, a feed port and a discharge port are arranged on the both ends of the wind cooling chamber, a horizontal production line is arranged between the feed port and the discharge port, a plurality of upcast ventilation pipes and downcast ventilation pipes are arranged inside the wind cooling chamber. The upcast ventilation pipes and downcast ventilation pipes are separately arranged at the upper side and the lower side of the horizontal production line, a plurality of top nozzles which can jet air down are arranged on the upcast ventilation pipes, a plurality of lower nozzles which can jet air up are arranged on the downcast ventilation pipes, a gas circulator is arranged in the wind cooling chamber, an air inlet opening of the gas circulator is communicated with the wind cooling chamber, an air outlet opening of the gas circulator is communicated with the interior of the upcast ventilation pipes and downcast ventilation pipes, a built-in heat exchanger is arranged at the air inlet opening of the gas circulator. By arranging ventilation pipes on the upward side and lower side of the horizontal production line, strong convection can be formed by the cold air which is jeted from the nozzles of the upcast ventilation pipes and the downcast ventilation pipes and the heat on the devices can be quickly removed.

Description

Technical field [0001] The invention relates to a rapid cooling chamber, which is mainly used in the rapid cooling stations of various "continuous industrial furnaces, heat treatment furnaces" production lines, such as the rapid cooling stations of annealing and normalizing production lines, especially various Forced cooling station of "protective atmosphere heat treatment furnace". Background technique [0002] At present, in the heat treatment equipment, the cooling chamber is mostly unidirectional air cooling. Choose Party B to set the blowing pipe above and below the horizontal assembly line. The blowing pipe can only blow in one direction, and the workpiece is cooled when passing through the cooling chamber. Since this cooling is unidirectional blowing, when cooling the workpiece, only one side surface of the workpiece can be cooled. Because the other side of the workpiece faces the air outlet, it is difficult for cold air to blow there. In addition, it was discovered during...

AI Technical Summary

Problems solved by technology

In addition, during use, it was found that because there is only one direction of blowing, the gas flow in the cooling chamber is difficult to control, and it is also easy to generate turbulent flow, and vacuum negative pressure is generated in local areas.

In this way, the outside air or the protective gas of adjacent components will flow back into the cooling chamber, thereby affecting the heat treatment effect of the workpiece.
