More excellent, the delivery port symmetric arrangement of two water inlet pipes.
Optimum, the delivery port of said water inlet pipe is an angular cut, the bottom surface of tangent plane and cool cycles water leg is relative.This structure can make the bottom of cooling circulating water chuck form eddy flow, eliminates the better effects if that is deposited on cool cycles water leg bottom water dirt thereby make.
The method of work of above-mentioned long-life uniform flow type high temperature blanking device is following:
(1) cooling water gets into the water inlet pipe of the helical structure in the cool cycles water leg, regulates flow, and cooling water is flowed to cool cycles water leg bottom direction with the flow velocity that is not less than 0.7m/s, and carries out heat exchange with the flowing water that cools back in the water chamber;
(2) cooling water flow out of water inlet pipe, forming eddy flow in the bottom of cool cycles water leg and getting into water chamber becomes and cools back flowing water;
(3) cooling back flowing water flow velocity with 0.7~1.5m/s in water chamber flows to cool cycles water leg top orientation; Simultaneously with shell body and water inlet pipe in cooling water carry out heat exchange; Discharge through the delivery port of water chamber at last, the discharge temperature that cools back flowing water is≤45 ℃.
Beneficial effect
1, the utility model is through changing traditional cooling water water inlet straight tube into the helical form water inlet pipe; Utilize this water inlet pipe and cool cycles water leg to form spiral helicine water chamber simultaneously; Do not have the current dead angle, solved existing cool cycles water leg and be prone to accumulate incrustation scale and cause the problem that the blanking device life-span is short, the equipment use cost is high.
2, because the utility model water inlet pipe and water chamber adopt helicoidal structure, the flow process that has prolonged current helps the heat exchange of cooling water, thereby makes the maintenance cost and the fault rate of the equipment of greatly reducing, and can reduce the generation of safety in production problem.
3, cooling water progressively heats up in water inlet pipe, thereby reduces cooling water thermal shock for blanking device bottom metal structural member when the delivery port of water inlet pipe flows out, and improves the metal structure life-span.
