Specific embodiment
The present invention is described in further detail below with reference to embodiment, embodiments of the present invention are not limited thereto.
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 preferred embodiments of the invention, exit vacuum chamber 3 is moved backward, outlet purging platform 4 is removed, in original
There is the position of exit vacuum chamber 3 to increase by 2 rear spray device for cooling 6, 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.
Two lateral walls of feed bin 64 are equipped with grating mounting rack 641, for installing grating (not shown), feed bin 64

One signal of portion's controller (not shown), the copper pipe for allowing front end are parked in desired position.It is convenient to top nozzle plate in this way
631 and lower nozzle plate 651 on nozzle be configured, the nozzle being arranged on conventional spout plate frequently with uniformly distributed mode, for
For copper pipe, when into feed bin 64, uniformly distributed nozzle cannot be guaranteed to be directed at copper pipe completely, will appear cooling effect unevenness in this way
It is even, the case where cooling time is difficult to control.Copper pipe is wound in plate-like, is placed on material rack special 7, material 7 top plan view of frame is such as
Shown in Fig. 7.In the present embodiment, material frame 7 is provided with the rest area of 8 copper pipe disks.It will be on top nozzle plate 631 and lower nozzle plate 651
Nozzle location setting alignment copper pipe disk.Material frame 7 can be accurately positioned, be made after expecting that frame 7 enters feed bin 64, copper using grating
Pipe dish just rests between the nozzle on top nozzle plate 631 and lower nozzle plate 651, guarantees cooling uniform.It can both reduce in this way
The quantity that nozzle is laid, also can be improved cooling efficiency.
When cooling work, the material frame 7 equipped with copper pipe disk that device for cooling 2 comes out is sprayed in the past and is admitted in feed bin 64, grating is fixed
The stop place of position material frame 7, it is ensured that copper pipe disk is between upper and lower nozzle, and circulating fan 61 is by the cold air of water cooling heat exchanger 62
It is sent into upper spray box 63 and lower spray box 65 by air duct, is sprayed by nozzle, cold air is sprayed to copper pipe disk up and down, is reached quickly
The effect of even cooling.
The above is only present pre-ferred embodiments, is not intended to limit the scope of the present invention, therefore
Any subtle modifications, equivalent variations and modifications to the above embodiments according to the technical essence of the invention, still fall within
Protection scope of the present invention.
