Specific embodiment
The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is not
It is limited to this.
If Fig. 1 is the cooling system of the roller bottom type annealing furnace of the prior art, it is mainly used on copper pipe processing production line, presses
Copper pipe advance horizontal direction is successively arranged latter cold section 1, preceding spray device for cooling 2, exit vacuum chamber 3, outlet purging platform 4 and blanking be with defeated
Trolley 5 is sent, preceding spray device for cooling 2 there are two, is to be provided with two pieces of water cooling heat exchangers placed vertically at air outlet, is set by top
The circulating fan set brings the heat of copper pipe surface to water cooling heat exchanger, and cooling effect is poor, and cooling efficiency is low.Tapping temperature reaches
60 DEG C or more, copper pipe appearance will appear oxidation.
If Fig. 2~7 are the preferred embodiments of the utility model, exit vacuum chamber 3 is moved backward, removes outlet purging platform 4,
Increase by 2 rear spray device for cooling 6 in the position of original exit vacuum chamber 3, the rear device for cooling 6 that sprays is long efficient quickly cooling device.
Spray device for cooling 6 successively includes circulating fan 61, water cooling heat exchanger 62, upper spray box 63,64 and of feed bin from top to bottom afterwards
Lower spray box 65,
There is the connection of air duct 611 between circulating fan 61 and upper spray box 63 and lower spray box 65.Upper spray is equipped with below upper spray box 63
Mouth plate 631, the top of lower spray box 65 are equipped with lower nozzle plate 651, and water cooling heat exchanger 62 is water cooling heat-exchangers of the plate type, cold with preceding spray
Unlike device 2, in the present embodiment, water cooling heat exchanger 62 is placed across below the air inlet of circulating fan 61.Copper pipe into
Enter in feed bin 64, circulating fan 61 drives the cold airflow of water cooling heat exchanger 62 to enter top nozzle plate 631 under by air duct 611
Nozzle plate 651, high speed cold airflow pass through copper pipe upper and lower surface and take away heat.Water temperature in water cooling heat exchanger 62 is controlled 20~30
Between DEG C, preferably 28 DEG C are preferred, and are circulated by normal-temperature water injection.It is equipped with sliding rail 621 below water cooling heat exchanger 62, conveniently changes
Hot device maintenance replacement.
