Solid fuel 2.5-3.8kg.Currently, improving mixture of sintering machine temperature, there are many approaches and methods, wherein in mix mine groove
It is used by many manufacturing enterprises using the method for steam preheating mixing material, but existing utilization steam preheating promotes sintered compound material temperature
The device of degree is that superheated steam is passed through into mix mine groove by pipeline, due to superheat steam pipeline unreasonable structure, gas outlet
Quantity is few, and mixture cannot be contacted with superheated steam completely so that mixture uneven heating is even, and mixture temperature is difficult after preheating
70 DEG C are broken through, and heat exchange effect is poor, and heat source is caused to waste.
Utility model content
The utility model provides a kind of device for promoting sinter mixture temperature, it is intended to by steam pipework and steaming
The optimization design of vapour nozzle structure enables superheated steam to be come into full contact with sinter mixture, convection current heat transfer, is sintered after ensureing preheating
Mixture temperature meets related technology requirement, improves heat exchanger effectiveness, reduces fuel consumption, improve production efficiency.
To achieve the above object, the utility model adopts the following technical solution：
A kind of device for promoting sinter mixture temperature, including main line and two groups of branch pipelines；Before the main line
End is connect with source of superheated steam, rear end and two component piping connections；It is vertical that two groups of branch pipelines are arranged symmetrically in mix mine groove
The both sides of direction central axis, are uniformly arranged several steam jets in each group of branch pipeline, and the steam jet dips down
Tiltedly arrangement, nozzle position use taper closing-in structure.
The above-mentioned device for promoting sinter mixture temperature is set on the outside of the branch pipeline tube wall and above steam jet
It sets for baffle sinter mixture, reduce the protection angle steel worn between sinter mixture and branch pipeline tube wall and steam jet.
The above-mentioned device for promoting sinter mixture temperature is reinforced in the branch pipeline and the setting of main line connecting portion
Lock.
The above-mentioned device for promoting sinter mixture temperature, two groups of branch pipeline lower ends are stretched into away from mix mine groove bottom
It it is 1.5-2 meters with mix mine groove bottom cloth round roller distance at 1/4-1/3 position.
The above-mentioned device for promoting sinter mixture temperature, the steam jet quantity being arranged in each group of branch pipeline are
9-13.
The above-mentioned device for promoting sinter mixture temperature, the nozzle position taper closing-in structure two of the steam jet
It is respectively d2=20mm, d1=25mm to hold diameter.
The utility model is a kind of device for promoting sinter mixture temperature, it is stretched into provided with two groups of lower ends away from mixed
The branch pipeline at 1/4-1/3 position of mine trench bottom is closed, and several steam jets are uniformly arranged in each group of branch pipeline, because
This can uniformly spray into superheated steam into mix mine groove by steam jet, at this point, under the driving of cloth round roller, mix mine groove
In sinter mixture slowly move downward, uniformly spread by the superheated steam sprayed in steam jet, filled with sinter mixture
Tap is touched, and forms convection current heat transfer modes, transfers heat to sinter mixture, and sinter mixture temperature is made to improve.Through on probation
It proves, good using the device heat exchange effect described in the utility model for promoting sinter mixture temperature, heat utilization efficiency can
Up to 95% or more, sinter mixture temperature can be improved to 85 DEG C or more, and productivity of sinter improves 15% or more.It can be seen that this
Utility model by the optimization design to steam pipework and steam jet structure, so that superheated steam is come into full contact with mixture,
Convection current is conducted heat, and to significantly improve heat exchanger effectiveness, is reduced fuel consumption, is improved production efficiency.
