Abstract
The invention relates to a furnace door and burner nozzle flame control device, which is arranged between a furnace and a burner nozzle, and comprises a position switch, two large-diameter solenoid valves, two small-diameter solenoid valves and a PLC (Programmable Logic Controller), wherein the burner nozzle is connected with an air inlet pipeline and a gas inlet pipeline which are respectively of a double-channel structure; one channel is provided with a large-diameter solenoid valve, and the other channel is provided with a small-diameter solenoid valve; the position switch is connected onto a furnace door; and the position switch and the four solenoid valves are respectively connected with the PLC. According to the invention, the flame size of the burner nozzle can be automatically adjusted, the production energy is saved, the working efficiency is high, and simultaneously, the heating and the heat preservation of the furnace can be maintained; and the furnace door and burner nozzle flame control device provided by the invention has a simple structure and low cost.
Description
Technical field
The present invention relates to the chain control device of burner flame size when a kind of furnace door is elevated, particularly relate to a kind of furnace door and burner nozzle flame control device.
Background technology
Kiln is common equipment workpiece being carried out to high-temperature heating, and the temperature in kiln burner hearth is very high generally will reach about 1250 DEG C, and when workpiece heat technique completes, workpiece will take out and carry out following process, and the fire door of kiln will be opened frequently.When a door is opened, natural gas combustion nozzle is also burning away, now have amount of heat and run out of from stove gate, and a large amount of heat energy of loss, causes the waste of the resources of production in vain, and the life safety of operating personnel also can not get ensureing simultaneously; Or extinguished by burner when a door is opened, refire burner when waiting fire door to shut, the heat energy loss in such kiln is serious, and need to reheat, production efficiency is lower.
Summary of the invention
The present invention provides a kind of safety, automation, the furnace door of economize energy and burner nozzle flame control device to overcome the above problems.
Technical scheme of the present invention is: described device is arranged between kiln and burner, comprise travel switch, two big orifice magnetic valves, two little bare sizing electro-magnetic valves, PLC control device, described burner is connected with intake stack and admission line, intake stack and admission line are all channel structure, a path is provided with big orifice magnetic valve, another path is provided with little bare sizing electro-magnetic valve, described travel switch is connected on fire door, and travel switch and above-mentioned four magnetic valves communicate with PLC control device respectively.
Described intake stack and admission line are all provided with ball valve.
The present invention is connected with fire door by travel switch, when fire door rise and fall, by PLC control device switch big orifice magnetic valve and little bare sizing electro-magnetic valve, thus automatically regulate the size of burner flame, saved the production energy, operating efficiency is high, can also keep the heating and thermal insulation to kiln simultaneously, structure of the present invention is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is kiln, and 2 is fire doors, and 3 is travel switches, and 4 is burners, 5 are big orifice magnetic valves one, 6 are big orifice magnetic valves two, 7 are little bare sizing electro-magnetic valves one, 8 is little bare sizing electro-magnetic valves two, 9 is intake stacks, and 10 is admission lines, and 11 is PLC control device, and 12 is ball valves.
Detailed description of the invention
A kind of furnace door and burner nozzle flame control device, described device is arranged between kiln 1 and burner 4, comprise travel switch 3, big orifice magnetic valve 1, big orifice magnetic valve 26, little bare sizing electro-magnetic valve 1, little bare sizing electro-magnetic valve 28, PLC control device 11, described burner 2 is connected with intake stack 9 and admission line 10, intake stack 9 and admission line 10 are all channel structure, a path is provided with big orifice magnetic valve, another path is provided with little bare sizing electro-magnetic valve, described travel switch 3 is connected on fire door 2, travel switch 3 and above-mentioned four magnetic valves communicate with PLC control device 11 respectively, described intake stack 9 and admission line 10 are all provided with ball valve 12.Decline to putting in place at fire door 2 and locate installation travel switch 3, travel switch 3 and four magnetic valves communicate with PLC control device 11, and big orifice magnetic valve 1 and big orifice magnetic valve 26 are opened, and little bare sizing electro-magnetic valve 1 and little bare sizing electro-magnetic valve 28 are closed; When fire door 2 is opened, travel switch 3 disconnects, and big orifice magnetic valve 1 and big orifice magnetic valve 26 are closed, and little bare sizing electro-magnetic valve 1 and little bare sizing electro-magnetic valve 28 are opened, and burner 4 keeps little fire burning; Otherwise when fire door 2 declines, burner 4 automatically switches to big fire burning.
