Description

Shield machine foaming system
Technical field:
The utility model relates to the system of the sediment improvement foam that shield machine is applied.
Background technology:
The power of shield machine foaming system is provided by two foam pump in the market, finally sprayed by multiple foam jet, its weak point is that power is inadequate, can not ensure that the water yield of all outlet ports is even, some foam jet non-foam may be caused to spray phenomenon.Its gas flow is few in addition, and foam generation does not reach instructions for use.
Summary of the invention:
Technical problem to be solved in the utility model is to provide one can ensure that multiple foam jet water yield is even, and each foam jet has foam to spray, and ensures the shield machine foaming system of foam generation abundance.
Above-mentioned purpose is achieved in that it comprises bubble chamber, bubble chamber is built with foam dope, bubble chamber is provided with inlet, connected by pipeline between the liquid outlet of bubble chamber and the entrance of booster pump, pipeline described in this is provided with ball valve, connected by pipeline between supercharging delivery side of pump and flow spoiler entrance, connected by pipeline between flow spoiler outlet and splitter inlet, current divider there are several export, also comprise the foam pump identical with current divider export volume and foam maker, connected by pipeline between each outlet of current divider and the foam pump entrance corresponding with it, pipeline between each outlet of current divider and each foam pump entrance is all provided with pneumatic ball valve, each foam pump outlet all and between the entrance of the foam maker corresponding with it is connected by pipeline,
Also comprise air compressor and two self-draining arrangements, wherein the entrance of first self-draining arrangement is connected by pipeline between exporting with air compressor, the outlet of first self-draining arrangement is connected by pipeline with between the entrance of second self-draining arrangement, this pipeline is provided with reducing valve, connected by pipeline between the outlet of second self-draining arrangement and point air parcel, divide on air parcel and have the outlet identical with foam maker quantity, the each outlet of air parcel is divided to be connected with the entrance of air flow controller by pipeline, the outlet of air flow controller has pipeline to be connected with the air inlet port of foam maker, the pipeline connected between air flow controller outlet and foam maker air inlet port is provided with one way valve successively, ball valve, one way valve, the foam produced in foam maker enters into through the pipeline that the nozzle of foam maker connects different needs place.
The utility model has the advantages that: during work, foam dope is assigned to each foam maker uniformly through current divider, the flow of each road foam solution controls by pneumatic ball valve, be provided with multiple foam pump, can be each foam line and power is provided, Shi Ge road foam solution can effectively flow, gas can keep dry after twice drainage sunk well, air flow controller can make gas influx reach requirement, one way valve can ensure that air does not flow backwards, ball valve can control the flowing of every road gas, the foam dope got by foam pump and together being entered in foam maker by air compressor air out, two media react in foam maker generate needed for foam solution.It can ensure that each foam jet water yield is even, and each foam jet has foam to spray, and ensures that foam generation is sufficient.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention:
With reference to accompanying drawing, it comprises bubble chamber 1, bubble chamber is built with foam dope, bubble chamber is provided with inlet 2, connected by pipeline between the liquid outlet of bubble chamber and the entrance of booster pump 3, pipeline described in this is provided with ball valve, connected by pipeline between supercharging delivery side of pump and flow spoiler 4 entrance, connected by pipeline between flow spoiler outlet and current divider 5 entrance, current divider there are several export, also comprise the foam pump 6 identical with current divider export volume and foam maker 7, connected by pipeline between each outlet of current divider and the foam pump entrance corresponding with it, pipeline between each outlet of current divider and each foam pump entrance is all provided with pneumatic ball valve 8, each foam pump outlet all and between the entrance of the foam maker corresponding with it is connected by pipeline,
Also comprise air compressor 9 and two self-draining arrangements 10, wherein the entrance of first self-draining arrangement is connected by pipeline between exporting with air compressor, the outlet of first self-draining arrangement is connected by pipeline with between the entrance of second self-draining arrangement, this pipeline is provided with reducing valve 11, connected by pipeline between the outlet of second self-draining arrangement and point air parcel 12, divide on air parcel and have the outlet identical with foam maker quantity, the each outlet of air parcel is divided to be connected by the entrance of pipeline with air flow controller 13, the outlet of air flow controller has pipeline to be connected with the air inlet port of foam maker, the pipeline connected between air flow controller outlet and foam maker air inlet port is provided with one way valve successively, ball valve, one way valve, the foam produced in foam maker enters into through the pipeline that the nozzle of foam maker connects different needs place.
