Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

the cooling water flow channel in the traditional casting roller adopts a vertical arrangement mode of a plurality of parallel water channels, the only factor determining the flow speed and the flow smoothness of the cooling water is the lift of the water pump and the stability of the water pump, the characteristic of liquid flow can be known, when the cooling water enters the flow channel from a water inlet hole, most of the cooling water inevitably flows towards the lower part of the flow channel due to the fact that the influence of gravity and resistance is not needed to be overcome, therefore, the cooling water in the flow channel below the water inlet hole can quickly and smoothly flow and easily enter a water outlet below the water inlet hole, the cooling water in the area above the water inlet hole flows unsmoothly, the heat transfer effect of a pair roller of the cooling water is further caused to be uneven, meanwhile, the problem of poor production effect is caused, although a certain relieving effect can be brought to the existing point by increasing the lift and the power of the water pump, the flowing-down cooling water flows more quickly, meanwhile, the power potential energy of the flowing-up cooling water is increased, the far-end pressure of the water inlet is increased, the problem that the flowing unsmoothly is overcome, the expected effect can not be achieved, and meanwhile, the serious waste of electric power resources is caused.

The utility model relates to an aluminum alloy casting roll with cooling water assists booster-type structure, including roller shell 3 and roller core 4, roller core 4 sets up in roller shell 3, and the surface of roller core 4 has seted up basin 2, basin 2 prolong the spiral setting of roller core 4 outer wall, basin 2 both sides are provided with brace rod 1, brace rod 1 circumferencial direction and the laminating of roller shell 3 inner wall, basin 2 root seted up inlet opening 7 and apopore 8, inlet opening 7 and apopore 8 are evenly laid in turn, one end of roller core 4 be provided with water inlet 6 and delivery port 5 along the axial, inlet opening 7 and water inlet 6 communicate, apopore 8 and delivery port 5 communicate; under the prerequisite that does not change inlet pressure, through with basin 2 spiral setting, form the runner that the slope set up, make inlet opening 7 below runner increase certain resistance, the runner reduces certain resistance above the water inlet 7, can automatically reduce the speed that the cooling water got into basin 2 back downflow from inlet opening 7, simultaneously can automatically increase the speed that the cooling water got into basin 2 backward upward flow from inlet opening 7, the spiral flow effect that the cooperation casting roll autogiration also can form the coolant liquid, effectively reduce energy loss, and then make inlet opening 7 go up, the coolant liquid velocity of flow of two lower directions is close as far as, thereby guarantee that the heat exchange efficiency of 3 each positions of roller shell is unanimous, thereby guarantee production quality.
