Abstract
The utility model discloses the automatic temperature controller of the boiler, and belongs to the technical field of the boiler control. The utility model is characterized in that: the interlayer of the boiler body 2 beside the boiler door opening 4 and the outer layer boiler wall are provided and fixed with a metal box 1; the parallel position of the interior of the metal box 1 and the box bottom is provided with a double metal sheet 6; the right end of the double metal sheet 6 is welded on the side wall of the metal box 1; the outside of the boiler door opening 4 is provided with a boiler door 5; the boiler door 5 is arranged on the outer shell of the boiler body through a door shaft 8; the door shaft 8 is provided with a reset spring 9; the inside of the boiler door 5 of the vicinity of the door shaft is welded with a push rod 7. The utility model realizes the goal of automatically controlling the temperature of the boiler control system through controlling the size of the opening degree of the boiler door, and has simple structure, low cost, convenient operation and maintenance, and safe and reliable use.
Description
One technical field
The utility model belongs to boiler control technology field.
Two background technologies
It is a kind of energy-efficient heat exchange new technology that the superconductive medium of using in the steam generator system conducts heat, and start-up temperature is low, heats up rapidly, and heat transfer rate is fast, thermal efficiency height, and market prospects are very wide.But when temperature was higher than 100 ℃, the pressure in the steam generator system was malleation, and temperature is high more, and pressure is high more, used to steam generator system and had brought potential safety hazard.Present how many realization control furnace temperature that only are artificial by control coal amount, very inconvenience operates.
Three technology contents
The utility model is the size by switching of control Boiler door and opening degree, realizes the purpose of control steam generator system temperature automatically, and the boiler furnace temperature is controlled in the secure setting automatically.
The utility model is achieved in that on the interlayer of the boiler body 2 on stove gate 4 sides and outer furnace wall and is mounted with can 1, be provided with bimetal leaf 6 with box bottom surface parallel position in can 1, the right-hand member of bimetal leaf 6 is weldingly fixed on the sidewall of can 1; Arranged outside at stove gate 4 has fire door 5, fire door 5 is installed on the body of heater shell by door-hinge 8, door-hinge 8 is provided with back-moving spring 9, near door-hinge fire door 5 inboards are welded with push rod 7, push rod 7 is mutual upright position with fire door, the top of push rod 7 is fixed with trundle, withstands the left end of bimetal leaf 6.
The beneficial effects of the utility model are: after boiler temperature reached setting value, fire door was just opened respective degrees automatically, and this has just reduced the ignition temperature in the burner hearth, and the temperature in the steam generator system just can not raise again, has guaranteed user's safety.When boiler temperature was lower than setting value, fire door will be closed corresponding angle automatically, and until Close All, the ignition temperature in the burner hearth raises, and the temperature in the steam generator system improves thereupon.Move in circles like this, realized the purpose of automatic control steam generator system temperature.The utility model also can be applicable to control the size of boiler flue switching and opening degree, with the temperature of control steam generator system.
The utility model boiler temperature automaton is simple in structure, and is with low cost, and Operation and maintenance are convenient, and are safe and reliable.
Four description of drawings
Fig. 1 is a structural representation of the present utility model.
Five specific embodiment
The mounting means of boiler temperature automaton is, can 1 and boiler interlayer 3 are welded as a whole, and fire door 5 rotates around door-hinge 8, and the door-hinge place is equipped with back-moving spring, and fire door 5 is closed automatically.Fire door 5 inboards are fixed with push rod 7, and push rod 7 ends are provided with roller, to increase movable flexibility.
Superconductive mediums in the interlayer 3 of boiler body 2 with can 1 heating after, the bimetal leaf 6 outside perk that deforms.After the steam generator system temperature reached setting value, the distortion of bimetal leaf 6 promoted the elastic force that fire door 5 overcomes spring 9 by push rod 7, outwards opens around door-hinge 8; Boiler temperature is high more, and bimetal leaf 6 distortion are big more, and fire door 5 opening degrees are big more.And fire door 5 opening degrees are big more, and temperature is low more in the boiler furnace, and the temperature of boiler superconductive medium is just low more, and the distortion of bimetal leaf 6 is just more little, and the opening angle of fire door is more little, has realized the automatic control of boiler temperature.Set the length of different push rods 7, the height of steam generator system temperature in the time of can changing the fire door action, and make system temperature constant in the number range of setting.
Claims (2)
1. boiler temperature automaton, it is characterized in that: be mounted with can (1) on the interlayer (3) of the boiler body (2) by stove gate (4) and the outer furnace wall, be provided with bimetal leaf (6) with box bottom surface parallel position in can (1), the right-hand member of bimetal leaf (6) is weldingly fixed on the sidewall of can (1); Arranged outside at stove gate (4) has fire door (5), fire door (5) is installed on the body of heater shell by door-hinge (8), door-hinge (8) is provided with back-moving spring (9), near fire door door-hinge (5) inboard is welded with push rod (7), push rod (7) is mutual upright position with fire door (5), and the left end of bimetal leaf 6 is withstood in the end of push rod (7).
2. according to the described boiler temperature automaton of claim 1, it is characterized in that: the top of push rod (7) is fixed with trundle.
