Abstract
The utility model utility provides a mouth pulse controller with low cost, simple structure and low maintaining cost. The structure of the utility model is that the output of a temperature transducer in the furnace connects a comparator in the PLC, the output of the comparator connects a pulse generator in the PLC and the output of the pulse generator connects an air control valve in the mouth. The temperature in the furnace and the preestablished temperature are compared by the PLC; if the temperature in the furnace is lower, then PLC will output pulse to make the flame ejected from the mouth minish right away. The mouth pulse controller can make the furnace heat up rapidly, make the temperature stable and improve the availability of the equipment, having the advantages of little heat wastage, saving energy consumption, simple structure and low producing cost.
Description
Technical field
The utility model relates to gas furnace burner impulse controller, specifically, is a kind of burner impulse controller that is used on the annealing furnace.
Background technology
Burner impulse controller on the annealing furnace is the height according to temperature in the stove, determines each burner in chronological order in the burning time of certain hour section by impulse controller, and promptly each burner is the control device that burns in turn in chronological order in certain time period.At present, the burner impulse controller is produced by offshore company, its complex structure, and the price height, maintenance is inconvenient, and service life is short.
Summary of the invention
The purpose of this utility model provides a kind of with low cost, simple in structure, burner impulse controller that maintenance cost is low.
This gas furnace burner impulse controller, the output that is arranged on the temperature sensor in the stove connects the interior comparator of PLC, and the output of comparator connects the impulse generator in the PLC, and the output of impulse generator connects the air shut-off valve of burner.
Its operation principle: PLC compares temperature and predefined temperature in the detected stove of temperature sensor, if the former is less, comparator is clamp-pulse generator output positive pulse then, makes the air shut-off valve opening degree of burner become big, and the flame of burner ejection promptly increases; Otherwise if the former is bigger, comparator is clamp-pulse generator output negative pulse then, makes the air shut-off valve opening degree of burner diminish, and the flame of burner ejection promptly reduces.
As further improvement, in the above-mentioned gas furnace burner impulse controller, the air shut-off valve of a plurality of burners connects the output of impulse generator respectively, and the time controller in the PLC connects impulse generator.Like this, this burner impulse controller can be controlled a plurality of burners, determines the burning time of each burner in the certain hour section by time controller by the time sequencing of setting, and promptly each burner is burning in turn in chronological order in certain time period.
This burner impulse controller can make stove be rapidly heated, and the temperature ripple disable increases utilization rate of equipment and installations, few, the energy efficient of heat loss; Simple in structure, long service life, easy to maintenance; The long service life of burner lowers equipment maintenance cost; Low cost of manufacture, thus the annealing furnace cost reduced.
Description of drawings
Fig. 1 uses reference diagram for the burner impulse controller
Fig. 2 is the wiring schematic diagram of burner impulse controller.
Fig. 3 is the simple and easy schematic diagram of Fig. 2.
The specific embodiment
Among Fig. 1, the output of temperature sensor connects the comparator in the PLC, and the output of comparator connects the impulse generator in the PLC, and the output of impulse generator connects the air shut-off valve of 1#, 2# burner, and the time controller in the PLC connects impulse generator.
Among Fig. 2,3, L, N are the PLC power supply; L+, 0V are the PLC output end power; SA is that burner manually and is automatically controlled selector switch; SB1 is the air shut-off valve of 1# burner; SB2 is the air shut-off valve of 2# burner; BO is the temperature controller output point; HL1, HL2 are indicator lamp; KA1, KA2 are auxiliary reclay; Coil is connected with PLCL, the air shut-off valve of normally opened contact control burner.
The program that establishment is arranged in the PLC in advance, SA switch are selected when manual, and SB1, SB2 control KA1, KA2 coil cause KA1, KA2 normally opened contact closure to control the unlatching of burner actuator, close, and simultaneously corresponding indicator lamp is lighted.The SA switch is selected when automatic, PLC according to temperature sensor output signal control the burner actuator unlatching, close.When temperature is lower than design temperature in the detected stove of temperature sensor, control each burner combustion time with PLC internal time controller, burning is rapidly heated thereby reach successively.
This gas furnace burner impulse controller can satisfy large-scale heat-treatment production line automation, modern requirement, and has fallen at the end combustion gas continuous annealing furnace manufacturing cost.With combustion gas continous way anneling production line is example: as anneling production line 20 heating warm areas, an impulse controller is joined in every district, uses at present the impulse controller (as German krom) of the cheapest external production, and cost is approximately ten thousand yuan of 3.5 ten thousand * 20=70; But this burner impulse controller, cost are approximately ten thousand yuan of (PLC+3 switch+1 power supply+4 indicator lamp+2 auxiliary reclay+1 150 ※, 200 ※, 140 switch boards) * 20=(1800+300+30+20+50+120) * 20=4.64.Find out that thus it is obvious that the utility model is saved cost effectiveness, have only external production controller 1/15.
Claims (2)
1. gas furnace burner impulse controller is characterized in that: the output that is arranged on the temperature sensor in the stove connects the comparator in the PLC, and the output of comparator connects the impulse generator in the PLC, and the output of impulse generator connects the air shut-off valve of burner.
2. according to the described gas furnace burner of claim 1 impulse controller, it is characterized in that: the air shut-off valve of a plurality of burners connects the output of impulse generator respectively, and the time controller in the PLC connects impulse generator.
