Wherein, Said dividing plate comprises first dividing plate and second partition, and said first dividing plate is hollow tube-shape, and first dividing plate is along the axial setting of cylindrical shell; The open rearward end of first dividing plate is connected on the cylinder inboard wall of said water-in periphery; The front opening of first dividing plate is near said front end end cover, and said second partition is around on the outside surface that is arranged on said first dividing plate, and second partition extends to the rear end of second partition from the axial screw of the front end edge cylindrical shell of first dividing plate.
Wherein, said second partition extends with the outside surface spiral of uniform distances along said first dividing plate.
Wherein, said first dividing plate and second partition are one-body molded.
Wherein, said body is welded to form by preceding cylindrical shell and rear cylinder body butt joint, and said rear cylinder body is a weldless steel tube, and said preceding cylindrical shell is a fine copper cast tube spare, and the weld seam of preceding cylindrical shell and rear cylinder body is arranged in the rear end of copper cooling stud.
The utility model is different from prior art, has the following advantages: because water coolant directly passes to the copper cooling stud foremost, accelerated the flow velocity of front end; Make the cooling that strengthened of high temperature damageable zone, improved the rate of heat exchange of copper cooling stud front end high-temperature zone, and then circled round to the rear end of copper cooling stud; Make the copper cooling stud obtain evenly comprehensively cooling, eliminated cooling dead angle and air chamber, reduced the copper cooling stud and can not in time derive the melting loss that causes because of superthermal load; Improved work-ing life; Simultaneously can make blast furnace recover the body of heater refrigerating function in the short period of time, prolong the work-ing life of blast furnace, improve the safety in production of blast furnace.

Embodiment
By the technology contents, the structural attitude that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
With reference to shown in Figure 1; The copper cooling stud of the utility model comprises body, and said body is the cylindrical shell 1 of hollow; The front port of cylindrical shell 1 is provided with front end end cover 7; The rear port of cylindrical shell 1 is provided with rear end cap 8, is fixed with the grouting ring flange of water inlet pipe 2, rising pipe 3, ring flange 4 and band grout pipe 5 on the said cylindrical shell 1, and the water-in of offering on the rear end cap 8 of said water inlet pipe 2 through cylindrical shell 1 100 communicates with cylindrical shell 1; The water outlet of offering on the rear end sidewall of said rising pipe 3 through cylindrical shell 1 101 communicates with cylindrical shell 1; Be provided with dividing plate 6 in the said cylindrical shell 1, said dividing plate 6 is divided into one with space in the cylindrical shell 1 and crosses aquaporin, and the said aquaporin of crossing leads to the rear end of cylindrical shell 1 and passes to water outlet 101 along the spiral inner wall formula of cylindrical shell 1 again from the front end that water-in 100 first straight lines lead to cylindrical shell 1.
During work, water coolant feeds in the cylindrical shell from water inlet pipe, under the guiding of crossing aquaporin, directly passes to the copper cooling stud foremost earlier; Accelerate the flow velocity of front end, made the cooling that strengthened of the high temperature damageable zone of front end, improved the rate of heat exchange of copper cooling stud front end high-temperature zone; And then lead to the rear end of copper cooling stud and finally discharge from water outlet in the spiral inner wall formula of the guiding lower edge cylindrical shell of crossing aquaporin; Make copper cooling stud integral body obtain evenly comprehensively cooling, eliminated cooling dead angle and air chamber, reduced the copper cooling stud and can not in time derive the melting loss that causes because of superthermal load; Improved work-ing life; Simultaneously can make blast furnace recover the body of heater refrigerating function in the short period of time, prolong the work-ing life of blast furnace, improve the safety in production of blast furnace.
