Changing under technology contents without essence, when being also considered as the enforceable category of the present invention.
Fig. 1 is the schematic diagram of concrete standard fog room environment adjustment system of the present invention.As it is shown in figure 1, this
Invention concrete standard fog room environment adjustment system is mainly used in adjusting concrete standard maintenance under low temperature environment
The temperature and humidity of room, it specifically includes that steam generation water tank 10, sealing radiator 20, spray assemblies 30
And control assembly 40.
Steam generation water tank 10 is arranged at inside concrete standard fog room, and it is uncovered for Plate Welding one-tenth
Water tank.The heater 11 being connected to control assembly 40 it is provided with in the bottom of steam generation water tank 10,
The moisture in water tank 10 is there is in heater 11 for adding hot steam under the control controlling assembly 40.Water
Water in steam generation water tank 10 can generate steam after being heated, and the water vapour of generation is used for keeping concrete mark
The heat that is stable and that give out with steam of the air humidity within quasi-fog room can promote water coagulation soil
Temperature in standard curing room.
Steam generation water tank 10 is internally provided with water tank temperature sensor 24 and is controlled by control assembly 40
Heater 11.Control assembly 40 to be measured in steam generation water tank 10 by water tank temperature sensor 24
The water temperature in portion, when water temperature is less than water temperature threshold value, control assembly 40 controls heater 11 and sends out steam
Raw water tank 10 carries out heating to promote the water temperature in steam generation water tank 10 to target temperature.
Being internally provided with sealing radiator 20 at steam generation water tank 10, sealing radiator 20 is immersed in steam
Below the liquid level of water tank 10 occurs, and the liquid level of steam generation water tank 10 is higher than the upper surface of sealing radiator 20
150mm.Sealing radiator 20 is formed by Plate Welding, and it includes delivery port 21 and a water inlet 22.Go out
The mouth of a river 22 connects spray assemblies 30.Spray assemblies 30 includes that a pipeline 31 and interval are installed on pipeline
Spray head 32 on 31.Spray assemblies 30 is converted by the water in spray head 32 in the future self sealss water tank 20
For water mist spray in concrete standard mixes fog room.
Wherein water inlet 22 is connected to the water source 50 with certain pressure, between water source 50 and water inlet 22
Being provided with solenoid electric valve 23, solenoid electric valve 23 is connected to control assembly 40.Control when controlling assembly 40
When solenoid electric valve 23 turns on, water source 50 is to sealing radiator 20 water filling, when being full of water in sealing radiator 20
Time, the water in sealing radiator 20 enters in spray assemblies 30 under the effect of the pressure at water source 50.So when
When solenoid electric valve 23 turns on, sealing radiator 20 can utilize the hydraulic pressure at water source 50 by sealing radiator 20
Hot water exports to spray assemblies 30.This way of supplying water to spray assemblies 30 can make full use of water source
The hydraulic pressure of 50, it is also possible to avoid the booster water pump being provided for supplying water to spray assemblies 30 in water tank.
The water temperature generally ratio at the water source 50 supplied water to sealing radiator 20 at low ambient temperatures is relatively low, owing to sealing
Water tank 20 is immersed in steam generation water tank 10, therefore in the effect lower seal water tank 20 of heat transfer
Temperature can gradually rise up to identical with the temperature of steam generation water tank 10.Owing to using the mode pair of heat transfer
The sealing radiator 20 being soaked in steam generation water tank 10 heats, therefore the water in sealing radiator 20
Will not seethe with excitement, such sealing radiator 20 does not haves the excessive potential safety hazard brought of pressure after water boiling.
Control air humidity sensor 41, sky that assembly 40 includes being arranged in described concrete standard fog room
Temperature sensor 42 and controller 43.Air temperature sensor 42 and air humidity sensor 41
It is connected to controller 43.Detect that concrete standard is supported when controlling assembly 40 by air temperature sensor 42
When protecting the temperature in room less than air themperature threshold value, the controller 43 controlling assembly 40 controls heater 11
The temperature promoting steam generation water tank 10 and then the amount of the steam increasing the volatilization of steam generation water tank 10
To improve the temperature in concrete standard fog room and humidity.Sensed by air humidity when controlling assembly 40
Device 41 detects that the humidity in concrete standard fog room, less than air humidity threshold, controls the control of assembly 40
Device 43 processed controls solenoid electric valve 23 and turns on, and after solenoid electric valve 23 conducting, spray assemblies 30 is to concrete
Standard curing room sprays water smoke.Additionally the reference block in concrete standard fog room is also required to periodically spray
Water curing, controls assembly 40 and controls solenoid electric valve 23 and turn on when reference block needs maintenance, spray group
Part 30 sprays water smoke to reference block.
Steam generation water tank 10 and sealing radiator 20 in the present embodiment are Plate Welding and form.For
Prevent heater 11 and temperature is too high or electric leakage, heater 11 and be provided with overheated guarantor
Protection unit and earth leakage protective device.
Technical scheme makes it have following technique effect owing to using above technical scheme: the present invention
Technical scheme use hot water and steam and water smoke to maintain concrete standard fog room in temperature and humidity, keep away
Exempt from the use of air-conditioning.Use the mode the combining water tank sealing water to being soaked in steam generation water tank 10
Case 20 carries out heat transfer heating, brings potential safety hazard after so can avoiding the boiling of the water in sealing radiator 20.
The steam generation water tank producing hot water and steam also can heat and is positioned in sealing radiator for concrete test block maintenance
Cold water, it is to avoid use the quality problems that the maintenance of concrete test block is brought by cold water.Additionally sealing radiator
One end of 20 is connected to the water source other end and is connected to spray assemblies 30, so can directly utilize the hydraulic pressure at water source
Water in sealing radiator 20 is exported spray assemblies 30, it is to avoid booster water pump is set.
The above is only presently preferred embodiments of the present invention, and the present invention not does any pro forma limit
System, any those skilled in the art, the technology contents of available the disclosure above make a little change or
It is modified to the Equivalent embodiments of equivalent variations, as long as being the content without departing from technical solution of the present invention, according to this
Any simple modification, equivalent variations and the modification that above example is made by the technical spirit of invention, the most still belongs to
In the range of technical solution of the present invention.
