Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment can repeatedly make the blast furnace micro cooler of lining by mud jacking, including flange 6,
Cooling body 5, water inlet pipe 1 and outlet pipe 2, flange offer side pressure grouting mouth 4 on 6 end face；Cooling body 5 is arranged in flange 6
And be fixed on cooling wall 14 by flange 6,5 center of cooling body is equipped with center mud jacking mouth 3, center mud jacking mouth 3 and cooling body 5
Inner cavity 9 is formed with, inner cavity 9 connects respectively with water inlet pipe 1 and outlet pipe 2.
In the present embodiment, the diameter proportion of side pressure grouting mouth 4 and center mud jacking mouth 3 is 1：(2-3), the pressure of side pressure grouting mouth 4
Expect it is less, and if opening it is excessive, mounting hole when installing is then larger, is unfavorable for operating, and best side pressure grouting mouth 4 and center are pressed
The diameter proportion for starching mouth 3 is 1：2.
In order to which to cooling water, the heat transfer of blast furnace is ensured heat dissipation in time, cooling body 5 uses copper metal material system
It forms；In addition for the ease of processing, and with flange 6 is concentric installs or be welded as a whole.
From figure 1 it appears that water inlet pipe 1 is consistent with the diameter of outlet pipe 2, water inlet pipe 1, outlet pipe 2 are symmetrical arranged
On the flange 6 for cooling down 5 both sides of body, outlet pipe 2 is located at 1 top of water inlet pipe so that can be inhaled well into the water in inner cavity
Receive heat.
It can further be seen from figure 1 that the line angle between side pressure grouting mouth 4 and water inlet pipe 1, outlet pipe 2 is 90 °, tying
Reasonable Arrangement is carried out to side pressure grouting mouth, water inlet pipe and outlet pipe on structure, realizes structure optimization, processing is more convenient.
Embodiment 2
The present embodiment is identical with 1 basic structure of embodiment, difference lies in：As shown in Figures 2 and 3, it is provided with and leads in inner cavity 9
Stream set 10, flow guide sleeve can be made by copper metal material or other heat-conducting metals, and spiral shape is provided on flow guide sleeve 10
Flow deflector 12 and deflector hole 11, are provided with water inlet 7, water outlet 8 in flow guide sleeve 10 and 6 junction of flange, water outlet 8 be located at into
7 top of the mouth of a river, water inlet 7, water outlet 8 are connected respectively with water inlet pipe 1, outlet pipe 2.9 water route of inner cavity for cooling down body 5 uses
Chamber isolated, lower section is water inlet 7, and top is water outlet 8, and the water into inner cavity 9 can form vortex (see the annular arrow of Fig. 2
Head), cooling water is disturbed, because may be not present slough, it is more uniform that cooling water absorbs heat, and happens suddenly when cutting off the water in short-term, water conservancy diversion
It still has a surplus water in set, avoids blast furnace dry scaling loss bad, this technique effect is not that those skilled in the art can expect to obtain.
Wherein：10 length of flow guide sleeve is less than the length of inner cavity 9, and flow guide sleeve 10 and the inside of inner cavity 9 are formed with gap, lead
Discharge orifice 11 connects connection with gap；The screw pitch of spiral vane 12 is 3-4 times of 11 diameter of deflector hole, and best ratio is 3：
Arrow direction is water (flow) direction in 1, Fig. 2, and water route is unobstructed, and cooling water stroke is remote, and cooling water speed can be well controlled.
Schematically the utility model and embodiments thereof are described above, this describes no restricted, attached drawing
Shown in be also the utility model one of embodiment, practical structure is not limited thereto.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
The frame mode similar to the technical solution and embodiment, all should belong to the protection range of the utility model.
