Abstract
The utility model discloses a water cooling screen of an ore heating furnace combined type holding device, belonging to a water cooling device and comprising an outer arc plate, an inner arc plate and a water cooling loop between the outer arc plate and the inner plate; the outer arc plate and the inner arc plate form an enclosed space; the water cooling loop comprises an uplink loop horizontally retracing to an uplink from the bottom and leading to a water outlet. The uplink loop comprises a plurality of arc round bars horizontally welded between the outer arc plate and the inner arc plate and alternatively arranged to form uplink loop pipe walls in the enclosed space formed by the outer arc plate and the inner arc plate. The water cooling screen of an ore heating furnace combined type holding device has the advantage of novel conception and employs an arc round bar welding mode, which substantially reduces processing difficulty; bubbles are not remained on the top; the cooling water loop supplying water for the uplink from the bottom accords with the natural circulation principle; flow resistance of the cooling water is small; a maximized cooling area is guaranteed and water cooling effects are raised.
Description
Technical field
The utility model relates to a kind of water-cooling apparatus, and the concrete water-cooled that relates to the hot stove combined holder in a kind of ore deposit is protected screen.
Background technology
The combined holder electrode technology is by the exploitation of Norway Ai Ken company, and the eighties of last century the nineties is at first introduced on China's furnace of calcium carbide should technology.Adopt the composite electrode holder electrode technology, the failure rate of electrode reduces, and has improved the rate of starting of the hot stove in ore deposit, has the multi-efficiency of environmental protection, energy-conservation, consumption reduction, helps improving the overall technology level that the hot stove in ore deposit is produced.But traditional form ore deposit its one-time investment of hot stove is higher relatively, needs to be equipped with special-purpose electrode shell making apparatus.Existing water cooling plant cools off with the vertical direction mode of extending to horizontal direction of turning back through water inlet feedwater, the entrapped air pockets in the upper end of water-cooled conduit especially easily, and also circulating effect is undesirable.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides the water-cooled of a kind of good water-cooling effect, the hot stove combined holder in the rational ore deposit of cooling water channel to protect screen.
Technical scheme: for realizing above-mentioned purpose, the water-cooled of the hot stove combined holder in the ore deposit of the utility model is protected screen, comprises outer arc plate, inner arc plate, and is located at the water cooling labyrinth between outer arc plate and the inner arc plate; Said outer arc plate and inner arc plate form enclosure space, and said water cooling labyrinth comprises from the bottom beginning level up up loop that leads to delivery port of turning back.
As first kind of scheme of the utility model, said up loop comprises that several horizontal weldings are connected to the arc round steel between outer arc plate and the inner arc plate, alternately arranges in the said arc round steel enclosure space that arc plate and inner arc plate form outside and forms up loop tube wall.Specifically, the arc round steel is divided into two groups of both side ends that are welded in enclosure space respectively and also staggers mutually, keeps leaving between the round steel certain gap and makes two groups of round steel engagements, forms continuous " it " font loop.Said water cooling labyrinth also comprises descending water-cooled tube wall, and said descending water-cooled tube wall links to each other the initiating terminal of water inlet with up loop tube wall.
Adopt the inner arc plate of first kind of scheme to have polylith, the height of each piece inner arc plate is equivalent to the gap between adjacent two arc round steel.Can conveniently weld like this, improve working (machining) efficiency.
As second kind of scheme of the utility model, said up loop alternately is formed by connecting curved pipe and U type pipe.Said water cooling labyrinth also comprises the descending pipeline that water inlet goes downwards to the bottom and links to each other with up loop initiating terminal from the top.With respect to first kind of technical scheme, second kind of technical scheme directly adopts curved pipe and the U type pipe with spatial accommodation, and flow is big not as good as first kind of scheme, but simple in structure, easy for installation.
Beneficial effect: it is novel that the water-cooled of the hot stove combined holder in the ore deposit of the utility model is protected screen; Adopt the mode of arc round steel welding to reduce difficulty of processing greatly; The top can entrapped air pockets, and the cooling water channel that upwards supplies water from the bottom meets the natural circulation principle of water, and the cooling-water flow resistance is little; The maximization of assurance film-cooled heat improves the water-cooled effect.

Fig. 2 is the cutaway view in Figure 1A-A cross section.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1, the water-cooled of the hot stove combined holder in the ore deposit of the utility model is protected screen and is arcuate structure, wraps in hot stove combined holder outside, ore deposit.This water-cooled is protected screen and is comprised outer arc plate 1, inner arc plate 2, and is located at the water cooling labyrinth 3 between outer arc plate 1 and the inner arc plate 2; Outer arc plate 1 forms enclosure spaces with inner arc plate 2, and water cooling labyrinth 3 comprises from the bottom beginning level up up loop 5 that leads to delivery port 4 of turning back.
In conjunction with Fig. 1, shown in Figure 2; First kind of execution mode as the utility model; Up loop 5 comprises that several horizontal weldings are connected to the arc round steel 6 between outer arc plate 1 and the inner arc plate 2, and arc round steel 6 is alternately arranged in the enclosure space that outer arc plate 1 and inner arc plate 2 form and formed up loop tube wall.Specifically, arc round steel 6 is divided into two groups of both side ends that are welded in enclosure space respectively and also staggers mutually, keeps leaving between the round steel certain gap and makes two groups of round steel engagements, forms continuous " it " font loop.Water cooling labyrinth 3 also comprises descending water-cooled tube wall, and descending water-cooled tube wall links to each other the initiating terminal of water inlet 7 with up loop tube wall.Adopt the inner arc plate 2 of first kind of scheme to have polylith, the height of each piece inner arc plate 2 is equivalent to the gap between adjacent two arc round steel 6.Can conveniently weld like this, improve working (machining) efficiency.
The utility model also has second kind of scheme implementation mode, and up loop 5 alternately is formed by connecting curved pipe and U type pipe.Water cooling labyrinth 3 also comprises the descending pipeline that water inlet goes downwards to the bottom and links to each other with up loop initiating terminal from the top.
It below only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
