Abstract
The utility model discloses an outdoor anti-freezing balance container for a boiler, which comprises a balance container body connected with a boiler steam drum through a pipe. The external circumference of the balance container body is covered by a heating insulating device. Further, the heating insulating device is connected with an outdoor temperature detector probe through a controller. The preferred heating insulating device is formed by an insulating layer electric heating wires, wherein the insulating layer is coated on the external circumference of the balance container body and the electric heating wires are arranged in the insulating layer. Through the heating insulating device covering the external circumference of the balance container body, the problem that the readings are inaccurate in winter is thoroughly solved and thereby the potential safety hazards caused are avoided. Moreover, through arranging the external controller and the detector probe, the automatic control of the heating insulating device of the balance container is realized.
Description
Technical field
The utility model relates to the equalizing reservoir in the boiler drum level meter, refers to the open-air antifreeze equalizing reservoir of a kind of boiler particularly.
Technical background
As everyone knows, under the environment, its steam water-level meter generally adopts differential pressure water level gauge to boiler in the open, and the operation principle of this water level meter is poor according to carbonated drink severe, measures after convert by differential pressure transmitter and draws actual steam water-level.Equalizing reservoir is the critical piece of differential pressure water level gauge.When boiler normally moved, this kind water level meter was the most reliable.At present, when the employed equalizing reservoir of steam water-level meter came interim temperature to be lower than the set point of water in the winter time, it had water end (W.E.) to be frozen into ice easily, and the linker in the equalizing reservoir is stopped up, cause equalizing reservoir can't show current water level exactly, cause the blow-on time elongated.And, on drum, in the water process,, thereby mislead operating personnel, and then cause the generation of drum full water or lack of water accident if water level error occurs and easily causes steam water-level too high or too low, brought great harm for the safe operation of boiler plant.
Summary of the invention
The purpose of this utility model will provide a kind of boiler open-air antifreeze equalizing reservoir exactly, and it can effectively overcome the defective that existing boiler equalizing reservoir internal liquid solidifies easily under the low temperature environment, accurately shows the current water level of boiler.
For realizing this purpose, the open-air antifreeze equalizing reservoir of boiler that the utility model is designed comprises the equalizing reservoir body that links to each other with boiler-steam dome by pipeline, and its special character is: the periphery of described equalizing reservoir body is coated with heating and heat-insulating device.
Further, described heating and heat-insulating device by controller be arranged on open-air temperature detection probe and link to each other.
Further, described heating and heat-insulating device is made up of heat-insulation layer that is coated on equalizing reservoir body periphery and the electrical heating wire that is arranged in the heat-insulation layer.
Advantage of the present utility model is: by coating heating and heat-insulating device in the periphery of equalizing reservoir body, make the problem of equalizing reservoir read untrue in winter be solved, thereby avoided the potential safety hazard thereupon brought.Realized the automatic control of equalizing reservoir heating and heat-insulating device simultaneously by being provided with of external controller and detection probe.
Description of drawings
Accompanying drawing is the structural representation of the open-air antifreeze equalizing reservoir of a kind of boiler.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The open-air antifreeze equalizing reservoir of boiler shown in the figure, comprise the equalizing reservoir body 2 that links to each other with boiler-steam dome 1 by pipeline 7, be provided with linker 6, benchmark cup 8 and overflow pipe 9 in the equalizing reservoir body 2, the periphery of equalizing reservoir body 2 is coated with heating and heat-insulating device 3.Heating and heat-insulating device 3 is made up of heat-insulation layer 3b and the electrical heating wire 3a that is wrapped in the heat-insulation layer 3b.Heating and heat-insulating device 3 by controller 4 be arranged on open-air temperature detection probe 5 and link to each other.This controller 4 can use resistance bridge to measure temperature, adopts the thermistor of positive temperature coefficient, works as bridge balance, the differential voltage of output this moment is zero, works as variations in temperature, when causing the electric bridge disequilibrium, when being lower than 1 ℃ when temperature, because what adopt is the thermistor of positive temperature coefficient, this resistance reduces, and differential voltage is converted to single ended voltage behind operational amplifier, it is a negative value, make the triode conducting, relay gets electric, and heater strip begins heating.Temperature rises, when temperature surpasses 1 ℃, and electric bridge output positive voltage, triode ends, and relay discharges, and heater strip stops heating, and temperature descends.
The utility model in use, temperature detection probe 5 is gathered outdoor weather temperature signal, and a temperature signal that collects is sent into controller 4, automatically connecting heating and heat-insulating device 3 power supplys by controller 4 when outdoor weather temperature is lower than 1 ℃ starts working it, when outdoor weather temperature is higher than 1 ℃, disconnect heating and heat-insulating device 3 power supplys, this heating and heat-insulating device 3 is not worked.
Claims (3)
