Method uses electric heating.(2) water spot is more more than tubes rows, is difficult to drain Yu Shui.(3) pump chamber blows heating, and the section of control is limited, and one
A little regions antifreezing effect is poor.
Summary of the invention
Present invention seek to address that at least one the technical problems existing in the prior art.
For this purpose, the fire fighting truck pipe defroster good it is an advantage of the invention to provide a kind of antifreezing effect.
It is a further object of the invention to provide a kind of cooking for fire fighting truck with above-mentioned fire fighting truck pipe defroster
It prepares food device.
To achieve the above object, the embodiment of first aspect present invention provides a kind of fire fighting truck pipe defroster, packet
Include: feed pump, water cannon, antifreeze flow container and anti-icing fluid conveying device, the fire fighting truck pipe defroster have for connecting water
The water inlet of the water source import in source, the feed pump connects the water source import, the water outlet of the feed pump by water inlet line
Mouth connects the water cannon by primary flow pipe road, and the primary flow pipe road is equipped with water cannon valve, and the antifreeze flow container goes out
Liquid mouth connects the water inlet line or the primary flow pipe road, the anti-icing fluid conveying device setting by anti-icing fluid conveyance conduit
On the anti-icing fluid conveyance conduit.
This programme increases anti-icing fluid conveying device and the antifreeze flow container equipped with anti-icing fluid, fire-fighting in firemain system
After operation, antifreeze program can be started as needed, start anti-icing fluid conveying device, the anti-icing fluid in antifreeze flow container is defeated
It is sent to feed pump or primary flow pipe road, to send anti-icing fluid under the pump action of feed pump each to firemain system
In pipeline, anti-icing fluid is mixed with the remaining water guaranteed in pipeline, so that remaining water is not frozen, so that good antifreeze effect can be realized
Fruit prevents freezing pipeline component.
According to first embodiment of the invention, the anti-icing fluid conveying device includes venturi mixer, the text mound
In mixer there is working fluid import, driving fluid import and fluid-mixing outlet, the venturi mixer is mounted on institute
It states on anti-icing fluid conveyance conduit, the driving fluid import is made to connect the antifreeze flow container by the anti-icing fluid conveyance conduit
Liquid outlet, the fluid-mixing outlet connect the water inlet line or the primary flow pipe by the anti-icing fluid conveyance conduit
Road, the working fluid import connect the water outlet of the feed pump by mixer water inlet line, on mixer water inlet line
Equipped with mixer valve.
In the present solution, anti-icing fluid conveying device selects venturi mixer, cost is relatively low for such deisgn product, carries out fire-fighting
When operation, mixer valve closing, water cannon valve is opened, and water source import connects water source, and water pump is sent into master and gone out by feed pump operating
Waterpipe, so that water cannon be made to spray water.Fire-fighting operation terminate to bring into operation antifreeze program when, process control mixer valve is beaten automatically
It opens, feed pump operating at this time can send a part of water to primary flow pipe road, and another part water is sent in mixer water inlet line, makes
The working fluid import of venturi mixer is intake, and water can make during venturi mixer flows to fluid-mixing outlet
