Description
Technical field
The utility model relates to industrial furnace technology field more particularly to a kind of premixed combustion pipeline knots of step-by-step movement push rod furnace
Structure.
Background technique
Push rod furnace is one kind of industrial furnace, is mainly used for the heating of the metals embryo such as copper ingot.Main heating method is at present
Using the heat radiation of electrical heating elements, the air in burner hearth is heated, high temperature air is to metal embryo indirect heating.This kind of
The heating method connect has the following deficiencies: 1, and power consumption is very big, waste it is also more；2, heating speed is slow, low efficiency；It is above-mentioned to ask
It inscribes to be resolved.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, provide a kind of premix of step-by-step movement push rod furnace
Combustion pipe structure can quickly heat embryo material, and energy saving, and cost is relatively low.
The technical purpose of the utility model is achieved in that
A kind of premixed combustion pipeline configuration of step-by-step movement push rod furnace, it is characterised in that: including along burner hearth circumferential array and passing through
Through furnace wall outer surface several burners, be arranged in furnace wall outer surface and respectively one burner outer end of the cover several gas
Room, the air mixture pipeline being connect with each gas chamber, the T-type premixed device being connect with air mixture pipeline, respectively with T-type premixed device
The high temperature air pipeline and natural gas line of two entrances connection.
High-temperature expansion joint is equipped between the outlet and air mixture pipeline of the T-type premixed device.
The high temperature air pipeline is equipped with automatically controlled air control valve, and the two sides of automatically controlled air control valve are respectively equipped with manual sky
Gas butterfly valve.
The high temperature air pipeline, which is additionally provided with, manually controls bypass, this manually controls bypass across in two manual air butterflies
On the outside of valve, manually controls and also be provided with a manual air butterfly valve in bypass.
Balanced proportions valve, solenoid valve and manual ball valve are successively arranged on the natural gas line.
The utility model has the beneficial effect that the utility model using natural gas as the energy, directly adds after burning
Hot embryo material, heating is quick, high production efficiency, and can heat from multiple orientation to embryo material, so that embryo material is heated evenly, guarantee to produce
Quality.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the right side structural representation of the utility model.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
As shown in Fig. 1 to Fig. 2, a kind of premixed combustion pipeline configuration of step-by-step movement push rod furnace described in the utility model, packet
It includes with lower component:
Along 7 circumferential array of burner hearth and extend through several burners 2 of 5 outer surface of furnace wall；In Fig. 1, each section of burner hearth is set
There are four burners, and the left and right side of furnace charge each two, the flame of burner faces the ejection of embryo material 6；
Furnace wall outer surface and respectively several gas chambers 1 of one burner outer end of the cover, the periphery and furnace wall of gas chamber are set
Outer surface sealing；
The air mixture pipeline 3 connecting with each gas chamber after high temperature air is mixed with natural gas, passes through air mixture pipeline
It is sent into gas chamber, provides fuel to burner；
T-type premixed device 9；Its outlet is connect with air mixture pipeline, for mixing high temperature air and natural gas；
The high temperature air pipeline 12 and natural gas line 13 of connecting T-shaped premixed device two entrances.
High temperature air in high temperature air pipeline is by air at room temperature by rising after heat exchanger and push rod furnace exhaust gas heat exchange
Temperature, in order to keep the safety in production, air mixture is avoided to explode, the temperature of high temperature air there must be a upper limit value, such as can
To be set as the 50~70% of gas explosion ceiling temperature.
It is equipped with high-temperature expansion joint 8 between the outlet and air mixture pipeline of the T-type premixed device, combustion gas mixing can be compensated
Pipeline is because of high temperature bring axial deflection.
The high temperature air pipeline is equipped with automatically controlled air control valve 11, and the two sides of automatically controlled air control valve are respectively equipped with manually
Air butterfly valve 10.The high temperature air pipeline, which is additionally provided with, manually controls bypass 12-1, this manually controls bypass across in two hands
On the outside of dynamic air butterfly valve, manually controls and also be provided with a manual air butterfly valve 10 in bypass.It is successively set on the natural gas line
There are balanced proportions valve 14, solenoid valve 15 and manual ball valve 4.By adjusting the aperture of each valve, adjustable combustion gas and high temperature
The combined amount of air adapts to different embryo materials.
The working principle of the utility model is: high temperature air with natural gas after T-type premixed device mixes, by mixing fire
Feed channel is sent to each gas chamber, and supply burner combustion uses.
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this is practical new
Type can have various modifications and variations.Within the spirit and principle of the utility model, it is made it is any modification, equally replace
It changes, improve, should be included within the scope of protection of this utility model.
