Detailed Description
For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.
As shown in fig. 4-6, a water jacket cooling device comprises a water jacket shell, wherein the water jacket shell comprises an inner shell 1 and an outer shell 2 which are connected through a connecting piece to form an annular circulating water channel and a central cavity, a support 3 and a water jacket water outlet 4 are arranged at the bottom of the outer shell, a manhole 5 is arranged at the center of the top, a water jacket inner water outlet 6 and a water jacket inner overflow port 7 are arranged in the central cavity, the circulating water channel is divided into a plurality of cooling areas by a partition plate 8 between the inner shell and the outer shell, a circulating water inlet 9 is arranged at the opposite bottom of each cooling area, a circulating water outlet 10 is arranged at the opposite top of each cooling area, and cooling water flows from bottom to top, so that better heat exchange is realized.
The raw water jacket structure is only provided with a group of circulating water inlets and circulating water outlets, only a group of loops can be formed, the number of partitions is small, the water jacket structure can be divided into 2-6 loops, the number of partitions is more, the cooling rate can be more finely adjusted by regulating and controlling the partitions, and meanwhile, the strip steel 11 can be cooled more uniformly.
The connecting piece between the shell body and the inner shell body of the raw water jacket adopts the screw 12, the existing water jacket structure adopts the connecting circular tube 13 as the connecting piece, the contact area of the screw and the water flow is small, the disturbance of the contact area of the circular tube to the water flow is large, the convection heat exchange effect of the existing water jacket structure is enhanced, and the cooling capacity is improved.
