DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] As Figures 1-7 shown, a water-cooled roll for strip cooling includes a middle roll sleeve 1. Both ends of the middle roll sleeve 1 are detachably installed with side roll bodies 2 through fixing components. The fixing components include fixing collars 3 arranged on the outer sides of the side roll bodies 2. An annular clamping groove is formed between the fixing collars 3 and the side roll bodies 2. The end of the middle roll sleeve 1 is clamped inside the annular clamping groove, and the fixing collars 3 and the middle roll sleeve 1 are tightly connected through a plurality of locking members 4. Water passing cavities are left inside the side roll bodies 2, and a heat conducting member is arranged inside the middle roll sleeve 1; by providing the fixing collars 3 and the locking members 4, the side roll bodies 2 and the middle roll sleeve 1 can be fixedly assembled. One of the provided water passing cavities can introduce cold water into the middle roll sleeve 1, and the other water passing cavity can discharge the water inside the middle roll sleeve 1.

[0024] The heat conducting member includes a heat conducting sleeve 6 arranged inside the middle roll sleeve 1. A plurality of outer heat conducting fins 5 that abut against the inner wall of the middle roll sleeve 1 are equidistantly arranged along the circumferential direction on the outer side of the heat conducting sleeve 6. Cooling channels are formed between adjacent outer heat conducting fins 5, and inner heat conducting fins 7 are embedded on the corresponding heat conducting sleeves 6. A water distributing member is arranged at the end of the heat conducting sleeve 6 to communicate with the cooling channels; by providing the outer heat conducting fins 5, the heat conducting sleeve 6 and the inner heat conducting fins 7, the heat of the middle roll sleeve 1 can be conducted in sequence, so that the introduced cold water can quickly take away the heat.

[0025] The water distributing member includes a water distributing plate 10 hermetically clamped on the inner wall of the middle roll sleeve 1. Outer insertion sleeves 11 are arranged on the water distributing plate 10 at the corresponding positions of the cooling channels, and inner insertion sleeves 12 are arranged on the water distributing plate 10 at the corresponding positions of the heat conducting sleeve 6; by providing the water distributing plate 10, the outer insertion sleeves 11 and the inner insertion sleeves 12, the cold water introduced from the water passing cavity can be dispersedly conveyed to the cooling channels and the inside of the heat conducting sleeve 6. The cold water inside the cooling channels can quickly cool the middle roll sleeve 1 and the outer heat conducting fins 5, and the cold water inside the heat conducting sleeve 6 can cool the heat conducted by the heat conducting sleeve 6 and the inner heat conducting fins 7.

[0026] One end of the side roll body 2 close to the water distributing plate 10 is in a closed state, and outer insertion holes 8 and inner insertion holes 9 that match them are respectively arranged at the closed ends of the water distributing plate 10 at the corresponding positions of the outer insertion sleeve 11 and the inner insertion sleeve 12. Sealing rings 13 are sleeved outside the outer insertion sleeve 11 and the inner insertion sleeve 12. The sealing rings 13 seal the insertion gaps between the outer insertion sleeve 11 and the outer insertion holes 8 and between the inner insertion sleeve 12 and the inner insertion holes 9; by providing the outer insertion holes 8, the inner insertion holes 9 and the sealing rings 13, the sealing performance between the middle roll sleeve 1 and the side roll body 2 can be increased, and the leakage phenomenon can be avoided.

[0027] The outer heat-conducting fin 5, the heat-conducting sleeve 6 and the inner heat-conducting fin 7 are of an integral structure and are all made of heat-conducting metal materials.

[0028] Working principle: First, the device can fix and assemble the side roller body 2 and the middle roller sleeve 1 through the fixing component. Then, cold water is introduced into the inside of the middle roller sleeve 1 through a water passing cavity, and the water inside the middle roller sleeve 1 is discharged through another water passing cavity. Before the cold water is introduced into the inside of the middle roller sleeve 1, the water dividing member will disperse and convey the cold water introduced into the water passing cavity to the cooling channel and the inside of the heat-conducting sleeve 6. The cold water inside the cooling channel quickly cools the middle roller sleeve 1 and the outer heat-conducting fin 5. At the same time, the cold water inside the heat-conducting sleeve 6 cools the heat conducted by the heat-conducting sleeve 6 and the inner heat-conducting fin 7, thereby forming a state of inward contraction and cooling, greatly increasing the cooling surface of the cold water.

[0029] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
