Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to the improved structure of a kind of mobile froth apparatus, as shown in Figure 1-2, and foam liquid tank 1, inline inductor the 2, first foam gun the 3, second foam gun 4, water band 5 and assembly pulley 6.
Foam liquid tank 1 is provided with the first liquid outlet 11 and the second liquid outlet 12, is additionally provided with tank liquid mouth 13, leakage fluid dram 14, pushing hands 15 and hose bed 16. Tank liquid mouth 13 for storing up into foam solution in foam liquid tank 1, and leakage fluid dram 14 is for discharging the liquid in foam fluid reservoir. Assembly pulley 6 is assembled on the bottom of foam liquid tank 1, to drive foam liquid tank 1 to be movably walking. Pushing hands 15 setting is beneficial to operator and promotes foam liquid tank 1, hose bed 16 to be used for storing water band 5.
Inline inductor 2 is locked on foam liquid tank 1 top, and it has liquid inlet, water inlet and outlet. First liquid outlet 11 of foam liquid tank 1 connects the liquid inlet of inline inductor 2 by pipeline 7, and this pipeline 7 is sequentially provided with the first check-valves 71 and ball valve 72 along conveying direction.The top of pipeline 7 preferably stretches in foam liquid tank 1 and extends close to foam liquid tank 1 bottom position place. In the first disassembled outlet being connected to inline inductor 2 of foam gun 3, specifically, the outlet of inline inductor 2 is extended with pipeline, and the end of this pipeline is provided with hermaphroditic coupling 9, and the first foam gun 3 is disassembled when not using to be locked on hermaphroditic coupling 9 (as shown in Figure 1).
Preferably, the rear end pipeline of inline inductor 2 is additionally provided with gas-liquid cyclone mixer 8, it is provided with eddy flow baffle plate in gas-liquid cyclone mixer 8, this eddy flow baffle plate is provided with several whirl hole, these several whirl hole surround around the axis of blender and arrange, and are obliquely installed with angle in toward homonymy. Strengthen gas-liquid mixed effect by gas-liquid cyclone mixer 8, be beneficial to foam and produce and the uniform and stable property of foam.
Second foam gun 4 is as in figure 2 it is shown, include the front and back tube tooth interface 41 of assembly and connection, gun body 42 and gun barrel 43 successively. Being provided with hybrid chamber 421 in gun body 42, the sidewall of this gun body 42 is provided with the suction attachment 44 being connected with hybrid chamber 421; Suction attachment 44 connects pipette 49. Pipette 49 is stretched in foam liquid tank 1 by the second liquid outlet 12. The second check-valves 45 it is provided with in pipette 49. Preferably this second check-valves 45 is arranged on the position near its link of the correspondence in pipette 49, to give full play to its effect.
The front end of described hybrid chamber 421 offers water inlet 4211, and the place rearward in this hybrid chamber 421 is equiped with nozzle 46, and this nozzle 46 is to control flow and produce suction function. Gun body 42 is the bearing of foam gun, and tube tooth interface 41 is in order to be connected with water band. Being additionally provided with keying handle 47 and handwheel 48 in gun body 42, opening and closing handle 47 is foam gun cock and imbibition switch, and handwheel 48 is used for controlling foam gun and flows to, and gun barrel 43 is in order to regulate air foam liquid.
This new mobile type fixed froth installation is when fire extinguishing, first foam gun 3 and the second foam gun 4 can use simultaneously, wherein the tube tooth interface (water inlet and outlet) at the two ends of inline inductor 2 is all connected with fire hose 5, the water band Bonding pressure water source of water inlet, the other end of the water band in outlet connects the first foam gun 3, when there being the water being not less than 0.6MPa pressure to flow through the nozzle of inline inductor 2 with significantly high speed, diffusion due to the transverse shifting of jet particle, indoor formation vacuum (negative pressure) of inline inductor 2, then the foam solution in foam liquid tank 1 enters inline inductor 2 by pipeline 7 under the pressure effect of air, mix with press water, it is finally reached a certain proportion of mixed liquor. when having the mixing liquid stream of certain pressure to the first foam gun 3, because the performance of the first foam gun 3 can suck a certain amount of air, foam mixing liquid is made to foam, thus reaching the effect of foam fire-fighting.
It addition, the tube tooth interface 41 of the second foam gun 4 is directly connected to pressure water source, when press water is entered gun body 42 by water band through tube tooth interface 41, during by water inlet 4211, the space (hybrid chamber 421) constituted between gun body 42 and nozzle 46 forms negative pressure. Hybrid chamber 421 draws foam solution by pipette 49, makes foam solution mix in 6:94 ratio with water. When mixed liquor stream is by the nozzle entrance 461 of nozzle 46, spread atomization immediately, again form negative pressure and suck large quantity of air, mix with mixed liquor, produce air foam, produce good foam stream through the dynamic equilibrium in gun barrel 43 and eject.
The rear end of first, second two liquid outlets 1,12 is respectively equipped with first check-valves the 71, second check-valves 45, when maloperation or other fortuitous events occur, can prevent aqueous reflux from entering foam liquid tank 1, to guarantee that foam liquid tank 1, foam gun normally use, and the extinguishing effect of excellence.
Preferably, nozzle 46 is provided with the nozzle entrance 461 relative with water inlet 4211. The radial dimension of this water inlet 4211 is preferably greater than the radial dimension of nozzle entrance 461, is beneficial to negative pressure in this and is formed and atomizing effect.
Preferably, the junction of described suction attachment 44 is provided with sealing ring 411, and this sealing ring 411 can make pipette 49 vacuum seal, to guarantee negative-pressure liquid suction effect.
Preferably, gun barrel 43 offering suction hole, the axis of this suction hole is in from front to back toward tilted extended. This structural design is beneficial to suction hole and sucks large quantity of air, is finally beneficial to air foam and produces timely and effectively. Suction hole preferably can be provided with tandem two groups. Further, be also provided with pulverizer plate in gun barrel 43, this pulverizer plate is axially inclined to set relative to gun barrel 43, to strengthen mixed liquor diffusion atomizing effect, it addition, be also provided with foam screen in the rear of pulverizer plate, this foam screen is inclined to set equally, plays reinforcement air foam generation effect. Preferably, the free end of gun barrel 43 extends out thickening and is configured to reinforcement 431. When being in an emergency, answering back to by gun barrel 43, reinforcement 431 plays reinforcement gun barrel 43 and answers back to intensity effect. The gun barrel of the first foam gun 3 also can in like manner design.
The foregoing is only this novel preferred embodiment, all equalizations done with this novel right change and modify, and all should belong to this novel scope of the claims.
