Description
Technical field
The present invention relates to smelting equipment technical field, in particular to dumping furnace smelts Brown Alundum self-baking electrode cooling system.
Background technique
It is raw material that self-baking electrode, which is with anthracite, coke and pitch and tar, electrode paste is made at a certain temperature, so
Electrode paste is fitted into afterwards in the electrode shell being mounted on electric furnace, by thermal sintering.This electrode can be used continuously, and side makes
With the thermal sintering in spreading.Self-baking electrode is widely used in Brown Alundum electric furnace and furnace of calcium carbide because of simple process, at low cost
In.
Wherein external short power grid connects brasses with water-cooled cable by contact tube, and electric current is applied on electrode shell, from
And electrode paste is roasted, and brasses is fixed by external sheath, and conical ring is usually fixed in sheath, is bored
Shape ring plays the role of limit to brasses and holds tightly, and sheath bottom is fixed with loop pipe, due to protecting in Brown Alundum smelting process
Set and loop pipe are respectively positioned in electric arc furnaces, and the high-temperature flue gas and molten metal table that the Brown Alundum raw material of electric arc furnace high-temperature generates
The radiant heat in face, so that sheath and loop pipe are constantly in the condition of high temperature, in order to improve the service life of sheath and loop pipe,
It is necessary to improve design to the cooling water circulation path in sheath and loop pipe.
Summary of the invention
The present invention provides dumping furnaces to smelt Brown Alundum self-baking electrode cooling system, to solve sheath and ring in the prior art
Shape pipe is chronically in hot environment, so that the problem of service life reduces.
In order to achieve the above object, the technical solution of the present invention is as follows:
Dumping furnace smelts Brown Alundum self-baking electrode cooling system, including sheath, conical ring and loop pipe, conical ring are fixed on
Inside sheath, sheath includes that internal layer set and outer layer jacket, bottom and the loop pipe of sheath are fixed, internal layer set, outer layer jacket and loop pipe
Closed cooling chamber, the interior intake antrum that is axially arranged with along sheath of cooling chamber are formed, sheath tip is equipped with the water inlet of connection intake antrum
The water outlet that the outlet pipe managed and be connected to cooling chamber the water inlet equipped with connection intake antrum at loop pipe and is connected to cooling chamber.
The technical principle and effect of the technical program are:
1, cooling water enters in loop pipe from intake antrum in this programme, after entered in cooling chamber from water outlet, thus real
Show and cooled to sheath and loop pipe, has solved sheath in the prior art and loop pipe is chronically in hot environment,
So that the problem of service life reduces.
2, the cooling water of low temperature is first into loop pipe in this programme, since loop pipe is located at the bottom of sheath,
Near the Brown Alundum of high melt, therefore temperature is also highest, therefore the cooling water of low temperature is initially introduced in loop pipe,
Therefore with the continuous entrance of cooling water, cooling water can quickly cool down to the highest loop pipe of temperature.
Further, it is equipped with muti-piece water-stop sheet along the axial spacing of sheath in the cooling chamber, water-stop sheet divides cooling chamber
For multiple closed torus, opened up on water-stop sheet jagged.
The utility model has the advantages that in this way, the water flow flowed out through loop pipe can flow successively through from the bottom up each circulation by notch
Chamber, due in the actual production process, sheath bottom close to high melt Brown Alundum, therefore temperature be also it is higher, in this way
One side cooling water is set and flows to low temperature from high temperature, cooling effect is best, and on the other hand, the setting of water-stop sheet can be to water flow
Barrier effect is played, the flow velocity of water flow is slowed down, cooling water is enable to give full play to the effect of heat exchange.
Further, the outer layer jacket is made of muti-piece doughnut-shaped steel plate.
The utility model has the advantages that setting is in this way convenient for the connection between water-stop sheet and outer layer jacket, so as to form closed circulation
Chamber.
Further, each notch is close to intake antrum setting, and the notch on adjacent water-stop sheet is located at the two sides of cooling chamber.
The utility model has the advantages that for example, by the blocking of intake antrum, water flow can Xiang Yuan when water flow enters first torus
It flows, and just enters in second torus from notch after full of first torus, therefore in this way from intake antrum side
It is arranged and the filling of cooling water as far as possible is enabled to expire torus, improves the heat transfer effect of cooling water.
Further, it is fixed with water fender in the loop pipe, water fender is between water inlet and water outlet.
The utility model has the advantages that the setting of water fender, cold by the blocking of water fender when cooling water enters loop pipe through water inlet
But water is flowed only towards far from water fender direction, then could be discharged from water outlet, be enable cooling water in entire loop pipe
Interior flowing.
Further, the loop pipe is made of the steel pipe of two semicirculars.
The utility model has the advantages that loop pipe is made that water fender is arranged inside it of the steel pipe of two semicirculars.
Further, the water inlet and water outlet are close to water fender setting.
The utility model has the advantages that cooling water in this way flows " distance " longest passed through in loop pipe, can fill out to the greatest extent
Full of loop pipe, and the warm water after heat exchange is quickly discharged, it should be noted that if water outlet or water inlet are remote
From water fender, then cooling water can generate " delay " after entering in this section " distance " of water outlet or water inlet and water fender
The phenomenon that, prevent the warm water exchange heat herein after reduces the cooling effect to loop pipe from being quickly discharged.
Further, the support plate of connection conical ring, loop pipe and sheath is equipped between the conical ring and loop pipe.
The utility model has the advantages that support plate is arranged here, the stability of conical ring support brasses is on the one hand improved, is on the other hand mentioned
The stability that high loop pipe is connect with sheath, due to the loop pipe water impact intracavitary by cooling, loop pipe and sheath
Junction will not only bear the gravity of loop pipe and cooling water, while the impact force downward also subject to water flow, therefore in conical ring
The support plate being separately fixed on conical ring, loop pipe and sheath is set between loop pipe, to improve the stability of connection.
Further, the water fender is fixed with deflector between water inlet side and cyclic annular inside pipe wall, deflector
Upper surface is towards water inlet.
The utility model has the advantages that when entering loop pipe through water inlet due to cooling water, flow to the water flow at water fender will form it is " stagnant
Stay ", and the setting of deflector, the cooling water " being detained " herein can be allowed to flow along deflector to separate water fender side, and
The guiding function of deflector reduces " delay " time of water flow here, while deflector can also play support to water fender and add
Strong effect.
Further, the water inlet is vertically completely or partially projected on deflector.
The utility model has the advantages that can completely or partially be impacted on deflector from the water flow that water inlet flows out in this way, to alleviate
Impact force of the water flow to loop pipe.
