For those of ordinary skill, the specific meanings of the above terms in the present invention can be understood according to specific conditions.
Shenfu figure describes the charging hole device 100 according to an embodiment of the present invention for metallurgical furnace below.
As shown in Figure 1, the charging hole device 100 according to an embodiment of the present invention for metallurgical furnace may include charging saliva
It covers 1 and buries copper pipe 2.
Specifically, the feed opening 12 axially penetrated through along it is formed in feed opening water jacket 1, material can pass through feed opening 12
Into in metallurgical furnace, buries copper pipe 2 and cast in feed opening water jacket 1 around feed opening 12 with cooling to feed opening 12.
In the related technology, cooling chamber is formed in the side of feed opening, i.e. the cooling chamber side wall that is formed in feed opening water jacket
On, so that the side wall that feed opening water jacket forms feed opening is formed as hollow structure, cleared up in the inner wall to feed opening
When, it is easy to cause the side wall of feed opening to be punched and leakage accident occurs.
Charging hole device 100 according to an embodiment of the present invention as a result, is cast in feed opening water jacket 1 by that will bury copper pipe 2
And be arranged around feed opening 12, so that the cooling to feed opening 12 can not only be realized, and in the inner wall to feed opening 12
When being cleared up, the opposite external cooling chamber formed in feed opening 12 buries the probability that copper pipe 2 is punched and is beaten less than cooling chamber
To not only facilitate the cleaning to the inner wall of feed opening 12, but also the generation of leakage accident can be reduced or avoided in the probability worn,
Risk of explosion is reduced, the operation for stopping material maintenance is also reduced, improves the operating rate of metallurgical furnace.
Specifically, burying copper pipe 2 can cast in feed opening water jacket 1.For example, bury copper pipe 2 and feed opening water jacket 1 can be used it is pre-
It buries copper pipe casting in bronze and makes jacket structure for water, that is, bury copper pipe 2 and feed opening water jacket 1 can be to bury copper tube fine copper casting water jacket structure, have
Body, the water pipe that copper tube fine copper casting water jacket structure may include parent He be embedded in it is buried, wherein parent can be used pure
Casting in bronze is made, and the copper pipe being embedded in parent is whole, to can guarantee the fusion rate of casting base material and copper pipe, so that copper pipe is not permitted
Perhaps burn through.The finished product shape for burying copper tube fine copper casting water jacket structure in this way can be a copper solid circle, i.e. charging saliva
Set 1 can be solid structure, bury the inside that copper pipe 2 is located at feed opening water jacket 1, and exposed water inlet 21 and water outlet 22,
It can carry out through ball test and bulge test before factory, carry out bulge test before installing, so that it is guaranteed that water route is unobstructed and ne-leakage.
Feed opening water jacket 1 is solid construction as a result, and worker will not firmly excessive when clearing up inner wall bonding
There is a phenomenon where punching cavitation, through feed opening 12 side wall squeeze into condenser pipe 2 probability it is even more little, therefore can keep away substantially
Exempt from the generation of leakage accident, to not only reduce risk of explosion, also reduces the operation for stopping material maintenance, and then improve bottom blowing
The operating rate of furnace.Wherein it is understood that the pipe laying of charging hole device 100 can be copper tube, be also possible to stainless steel tube,
White Copper Tubes or Copper-nickel alloy tube etc..
In some embodiments of the invention, feed opening water jacket 1 can be integrally formed with copper pipe 2 is buried, thus to can be improved
Feed opening water jacket 1 and the structural strength for burying copper pipe 2 simplify feed opening water jacket 1 and bury the assembly technology of copper pipe 2.
Further, copper pipe 2 is buried with water inlet 21 and water outlet 22, and cold water enters from water inlet 21 buries copper pipe 2, passes through
It buries after copper pipe 2 exchanges heat and is flowed out from water outlet 22, water inlet 21 and water outlet 22 stretch out feed opening water jacket 1.Show in as shown in Figure 1
In example, water inlet 21 and water outlet 22 being oppositely arranged in the radial direction and respectively along feed opening water jacket 1 in feed opening water jacket 1
Radial direction extends.That is, water inlet 21 and water outlet 22 are located at the both ends of the radial direction of charging water jacket, water inlet
Mouth 21 and water outlet 22 stretch out the outside wall surface of feed opening water jacket 1 and extend in a radial direction.
It in some embodiments of the invention, can also include: fixing seat 3 for the charging hole device of metallurgical furnace 100, Gu
Part seat is welded on furnace body 200, fixing seat 3 have bolt hole 31, feed opening water jacket 1 by above it pressing device 4 compress and
Pressing device 4 is connected with fixing seat 3 by bolt 32.As a result, by fixing seat 3 to be conducive to feed opening water jacket 1 and furnace body
200 installation assembly, specifically limits fixation hole 31 in fixing seat 3, the lower end of fixation hole 31 towards extending in furnace body 200,
Feed opening water jacket 1 is stretched in furnace body 200 by fixation hole 31, is realized by the fixed installation of fixing seat 3 and feed opening water jacket 1
The installation of feed opening water jacket 1 is assembled.
Pressing device 4 is pressed on the top of feed opening water jacket 1, and in example as shown in Figure 1, pressing device 4 is mounted on
The top of feed opening water jacket 1,1 upper end of feed opening water jacket are at least partly set in pressing device 4.Pressing device 4 and fixing seat 3
It is connected by bolt 32 the upper end of feed opening water jacket 1 to be pressed between pressing device 4 and fixing seat 3, so as to upper and lower
Feed opening water jacket 1 is defined on direction, to improve the fixing assembling effect of feed opening water jacket 1.
The smelting furnace of the invention also provides a kind of charging hole device 100 for smelting furnace with above-described embodiment.
Smelting furnace according to an embodiment of the present invention, by the charging hole device for smelting furnace that above-described embodiment is arranged
100, it can prevent from causing feed opening water jacket 1 to be punched due to clearing up energetically and making the coolant liquid in cooling chamber in scale removal process
Leakage, and then can avoid that leakage accident occurs and brings risk of explosion, stop the behaviour of material maintenance caused by also can avoid thus
Make, so that the working efficiency of smelting furnace can be improved.
