Abstract
The invention relates to a water-cooled slag discharging runner head, which includes a runner head main body. Inside the runner head main body, a water cooling pipe is arranged; and a water inlet and a water outlet both communicating with the water cooling pipe are arranged on one side of the runner head main body. The inventive water-cooled slag discharging runner head has the advantages of simple structure, reasonable design, good cooling effect, prolonged service life of runner head, reduced equipment cost and maintenance amount, and normal operation of the whole set of blast furnace granulated slag treatment system.
Description
Technical field
The present invention relates to a kind of refrigerating unit of roughing runner head, especially a kind of water-cooled roughing runner head.
Background technology
At present, in handling the system of blast furnace granulated slag, all dispose the roughing runner head, its effect be the slag of blast furnace through the slag runner ditch head of flowing through, get into granulating device again, so the ditch head plays a part bridge between slag runner and granulating device.The roughing runner head that blast furnace iron notch is used in the prior art all lacks heat abstractor; The ditch head is often scorched by molten iron; After using one not long period, need change or repair, so just waste great amount of manpower and material resources, influence the normal operation of Handling Blast Furnace Granulated Slag system the ditch head.
Summary of the invention
The objective of the invention is to: to the problem that above-mentioned prior art exists, propose a kind of simple in structure, good cooling results, the water-cooled roughing runner head of long service life.
In order to reach above purpose, water-cooled roughing runner head of the present invention comprises ditch head body, and its improvements are that the inside of said body is provided with water cooled pipeline, is provided with water-in and the water outlet that is communicated with water cooled pipeline in a side of said body.
The present invention further improves, the hollow cavity of said body for being processed by the steel plate welding.
The present invention further improves again, at the surperficial slag place of flowing through of said body casting high temperature material.
Further perfect of the present invention is to be equipped with filtering net in said water-in and the water outlet.
The invention has the advantages that: water-cooled roughing runner header structure of the present invention is simple, reasonable in design, has favorable cooling effect, has prolonged the work-ing life of ditch head, has reduced the cost and the maintenance capacity of equipment, guarantees the normal operation of a whole set of Handling Blast Furnace Granulated Slag system.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Embodiment
Embodiment one
The water-cooled roughing runner head of present embodiment, its structure such as Fig. 1 comprise ditch head body 1 to shown in Figure 3; Body 1 hollow cavity for processing by the thick steel plate welding of 8mm, the inner chamber of cavity is a water cooled pipeline 2, is provided with water-in 3 and the water outlet 4 that is communicated with water cooled pipeline 2 in a side of body 1; Be equipped with filtering net in water-in 3 and the water outlet 4; The casting high temperature material at the surperficial slag place of flowing through of body 1, the surface of wearing and tearing ditch head burns out the ditch head when avoiding slag to flow through the ditch head.
During actual the use, water coolant adopts the relatively poor process water of water quality, often contains silt, foreign material etc. in the process water; Easy blocking water cooled pipeline 2 causes its flow to reduce, and in water-in 3, filtering net is set; Can stop silt etc. effectively, the mobile water coolant gets in the ditch heads through water-in 3 during work, the ditch head is carried out cooling heat dissipation after; Water flows out through water outlet 4 again, thereby keeps the works better of ditch head through cooling water recirculation system, prolongs its work-ing life.
Except that the foregoing description, the present invention also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of requirement of the present invention.
Claims (4)
1. a water-cooled roughing runner head comprises ditch head body, and it is characterized in that: the inside of said body is provided with water cooled pipeline, is provided with water-in and the water outlet that is communicated with water cooled pipeline in a side of said body.
2. water-cooled roughing runner head according to claim 1 is characterized in that: the hollow cavity of said body for being processed by the steel plate welding.
3. water-cooled roughing runner head according to claim 2 is characterized in that: at the surperficial slag place of flowing through of said body casting high temperature material.
