Two kind present mixed modes, if under the very big condition of fire water variation in discharge, can not guarantee the exact mixing ratio to influence the fire control effect of foam. The utility model discloses a normal blister foam liquid storage tank, air supply and fire control pressure water, normal blister foam liquid storage tank pass through pipe connection foam pump and proportion blender, the fire control pressure water pass through the pipeline and also connect the proportion blender, the proportion blender pass through pipeline reconnection foam generator, the air supply also connect foam generator, set up first -class gauge on the connecting line of foam pump and proportion blender, set up the second flowmeter between proportion blender and the foam generator. The utility model discloses flow to fire water and foam liquid carries out real time monitoring, and the regulation and control of being convenient for reach equitable mixing ratio.
Description
Technical field
This utility model is related to a kind of measurement injecting type proportion mixing device.
Background technology
At present, foaming system mainly has 2 kinds of forms, and one kind is balanced type proportion mixing device, is mechanical, electrical by water wheels
Machine, diesel engine etc. drive foam solution gear pump to inject foam solution toward in proportioner, then carry out foam solution by balanced valve
Flow back and must adjust, thus ensuring compliance with the foams mix ratio of requirement;Another kind is pressure type proportion mixing device, with capsule in storage
Store a certain amount of foam solution in tank, when fire water is through piping, have a road water to enter foam liquid tank extruding capsule,
Thus the foam solution in capsule is squeezed into proportioner being mixed, by orifice plate, flow is limited.Above two
Plant hybrid mode, if it is impossible to ensure correct mixing ratio, thus affecting foam in the case that fire water changes in flow rate is very big
Extinguishing effect.
Utility model content
The purpose of this utility model is to solve the problems, such as prior art, thus providing a kind of measurement injecting type ratio
Example mixing arrangement, carries out monitor in real time to the flow of fire water and foam solution, is easy to regulation and control and reaches rational mixing ratio.
The technical solution adopted in the utility model is:A kind of measurement injecting type proportion mixing device, including normal pressure foam solution
Storage tank, source of the gas and fire-fighting pressure water are it is characterised in that described normal pressure foam liquid tank connects foam pump and ratio by pipeline
Blender, described fire-fighting pressure water also connects proportioner by pipeline, and described proportioner is connected by pipeline again
Connect foam maker, described source of the gas also connects foam maker, setting the on the connecting line of foam pump and proportioner
Flow meters, arrange second flowmeter between proportioner and foam maker.
Also include switch board, described switch board connects first flowmeter and second flowmeter, and described switch board also connects
Connect frequency conversion motor, described frequency conversion motor connects foam pump.
The pressure that described fire-fighting pressure water enters proportioner is 0.6~1.2MPa.
Air relief valve is set between described source of the gas and foam maker, and gas enters foam maker through air relief valve.
Described flow is calculated as electromagnetic flowmeter.
This utility model increases electromagnetic flowmeter in the fire water inlet ductwork of proportioner and foam solution inlet ductwork,
Monitor in real time is carried out to the flow of fire water and foam solution, the PLC in electrical control cubicles compares to the flow signal of collection, then
Control converter that the rotating speed of frequency conversion motor is adjusted, frequency conversion motor drives foam pump to convey foam solution extremely by shaft coupling
Mixed in proportioner, be finally reached rational mixing ratio.
Brief description
Fig. 1 is structural representation of the present utility model;
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described further:
As shown in figure 1, a kind of measurement injecting type proportion mixing device, including normal pressure foam liquid tank 1, source of the gas 9 and fire-fighting
Press water, normal pressure foam liquid tank 1 connects foam pump 4 and proportioner 8 by pipeline, and fire-fighting pressure water is also connected by pipeline
Connect proportioner, proportioner reconnects foam maker 6 by pipeline, source of the gas also connects foam maker, foam pump
With the first electromagnetic flowmeter 5 is arranged on the connecting line of proportioner, setting the between proportioner and foam maker
Two effusion meters 7.Also include switch board 2, switch board connects first flowmeter and the second electromagnetic flowmeter, switch board is also connected with frequency conversion
Motor 3, frequency conversion motor connects foam pump.The pressure that fire-fighting pressure water enters proportioner is 0.6~1.2MPa.Source of the gas and bubble
Pressure gauge is set between foam generator, and pressure gauge connects switch board.
Operation principle:Fire-fighting pressure water (0.6~1.2MPa) enters proportioner, and switch board starts frequency conversion motor, becomes
Frequency motor drives foam pump, foam solution is injected proportioner, is mixed to form the foams mix of fixed proportion with fire water
Liquid, foam mixing liquid is flowed through special foam maker and is mixed with compressed gas, forms foam, sprays through feed-line to foam lance
Go out.
General operation:
1., in the state of device valve unlatching, open frequency conversion motor fan hot blast electromechanical source, manual controller switch is beaten
To " AUTO " state, press " system start-up " button, switch board automatic frequency conversion motor, collection fire water flow and foam solution
Flow is calculated, adjust automatically motor speed to correct mixing ratio, when needing to stop, pressing " system stopping " button.
2., in the state of device valve unlatching, open frequency conversion motor fan hot blast electromechanical source, rotate " increment type potentiometer "
Electric machine frequency original frequency is adjusted to 35HZ, presses manual controller " HAND " key, after frequency reaches original frequency, rotation " increases
Amount Middle Eocene device " is adjusted to electric machine frequency, and manually controller is controlled to frequency conversion motor frequency, observes fire water
Flow and foam flow quantity, manual calculations mixing ratio, as less than normal in mixing ratio, expanded motor frequency.As need stop motor, press
" OFF " key.
Listed above is only specific embodiment of the utility model, and this utility model is not limited to above example,
Can also there are many deformation.Those of ordinary skill in the art can directly derive from this utility model disclosure or associate
All deformation, be all considered as protection domain of the present utility model.
