Specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explains the present invention, is not limited to the present invention.
The invention provides a kind of water absorber of high-pressure fog dust suppression equipment, this water absorber includes water pump 7, flexible pipe 3
And with hose connection floating thing 2.The connection end 301 of flexible pipe 3 is connected with water pump 7, and the free end 302 of flexible pipe 3 is as water inlet
Mouth simultaneously can be mobile with SEA LEVEL VARIATION according to floating thing 2.So, when water absorber works, floating thing 2 can swim in water meter
Face, drives the water inlet of flexible pipe 3 to follow the change of water level and correspondingly shift position, can draw upper strata clear water all the time.By
This, efficiently solve the susceptible to plugging problem of shower nozzle of high-pressure fog dust suppression equipment.
In order to ensure that flexible pipe 3 can maintain the original state in a high voltage state, one of the present invention preferred embodiment in,
Flexible pipe 3 is wired hose, for example, it is possible to be polrvinyl chloride wired hose.In this case, it is embedded with steel due to inside flexible pipe 3
Silk skeleton, when water pump 7 works, steel-wire carcass has certain supporting role makes flexible pipe 3 will not deform.In addition, flexible pipe with
The decline of water level in tank, when generation is moved accordingly, be also not in the situation fractureing and affecting water suction.
The length of flexible pipe 3 is adapted with the excursion of water level.So, on the one hand can choose according to the actual requirements suitably
The flexible pipe 3 of length, to adapt to different supply flumes and specific construction environment.On the other hand can also avoid tank inside is made
Become injury, for example, if flexible pipe 3 oversize will disturbance bottom of gullet contamination precipitation layer, so that the water in tank is become cloudy and shadow
Ring the normal work of high-pressure fog dust suppression equipment.
As shown in Fig. 2 the water absorber of high-pressure fog dust suppression equipment includes the steel pipe 4 for connecting water pump 7 and flexible pipe 3.
Steel pipe 4 includes the Connectivity Section 401 for connecting and extend downwardly with water pump 7.Preferably, Connectivity Section 401 is arranged perpendicular to confession
Water-surface vertical in tank down, and extends to the upper area of the contamination precipitation layer of bottom of gullet.So, Connectivity Section 401 can
It is delivered to the bottom of supply flume with the suction producing when water pump 7 works.
Steel pipe 4 includes bending from the end of Connectivity Section 401 with bending segment 402 connected horizontally with flexible pipe 3.Specifically, curved
With respect to the bottom of Connectivity Section 401, to side bending, simultaneously the final diapire parallel to supply flume extends trisection 402.Bending segment
The top of the 402 impurities at bottom beds of precipitation being located at supply flume.Preferably, Connectivity Section 401 and bending segment 402 can for two sections mutually
Independent steel pipe, is connected by elbow bend 5 between the two.So, the suction that water pump 7 produces is first from the vertical court in Connectivity Section 401
Lower transmission, enters in the bending segment 402 arranging in horizontal direction afterwards.Elbow bend 5 can ensure that Connectivity Section 401 and bending segment
Seamlessly transitting between 402, and then ensure the unobstructed of water absorber.Further, since bending segment 402 and flexible pipe 3 level connection joint, because
This, flexible pipe 3 will not bend it is ensured that the serviceability of flexible pipe 3.
In order to prevent pipeline backwater, check-valves 6 are provided with Connectivity Section 401.Specifically, check-valves 6 are positioned close to directly
The region of angle elbow 5.Check-valves 6 can be lift check valve.So, in the case that suction is inadequate, in Connectivity Section 401
Water will not flow back in bending segment 402 and flexible pipe 3, enters without flowing out from water inlet.In addition, in order to prevent from sucking on the water surface
Float, is provided with drainage screen 1 on water inlet.Thus, it is possible to better ensure that shower nozzle will not be blocked by float.
In order to ensure the serviceability of floating thing 2, for example, it is to avoid, by aqueous corrosion, one in the present invention concrete for floating thing 2
Embodiment in, floating thing 2 preferably employs stainless steel material to be prepared and arranges glomeration.Easy to understand, spherical body is in water
Surface has preferable flotation property.Furthermore it is also possible to according to specifically situation, the spherical floating thing of rustless steel 2 can be designed
Size and the thickness of hollow wall.
It is connected with the short tube 101 that can play counterweight effect in the free end 302 of flexible pipe 3.Specifically, short tube 101 can be
Steel pipe, has the preset weight being adapted with floating thing 2.The center of spherical floating thing 2 is with the tube wall of short tube 101 along its length
Middle position connect.Thus, on the one hand can ensure that the free end of short tube 101 drop-down flexible pipe 3 under gravity, make
Water inlet immerses below the water surface, convenient absorbent all the time.On the other hand it is ensured that the gravity of the buoyancy of floating thing 2 and short tube 101
Between reach balance, so that short tube 101 level is suspended in water.Thus, it is possible to ensure water inlet all the time towards horizontal direction, effectively
Avoid the impurity sucking water supply trench bottom, and then ensure that shower nozzle is not plugged up.
Present invention also offers a kind of high-pressure fog dust suppression equipment, this high-pressure fog dust suppression equipment includes tank 200 and upper
The water absorber stated, the connection end 301 of flexible pipe 3 is located at the near-bottom of tank 200.In this manner it is ensured that the water in tank 200
Can be fully utilized, i.e. as long as the water level in tank does not drop to connection end below 301, high-pressure fog dust suppression sets
The standby work that can normally absorb water.
In sum, the invention provides a kind of water absorber for high-pressure fog dust suppression equipment, this water absorber has
There is adaptive water level anti-blocking shower nozzle.It is an advantage of the current invention that：The drainage screen of high-pressure fog dust suppression equipment can be reduced
And the cleaning frequency of shower nozzle, reduce the input of supply flume desilting equipment and Partial filtration equipment, effective control cost.Meanwhile,
Solve because of the severe water quality of ship loader style of opening supply flume, and the nozzle of the high-pressure fog dust suppression equipment leading to easily blocks not
The problem that can normally spray.In addition, the water absorber of the high-pressure fog dust suppression equipment of the present invention also has, structure is simple, making side
Just feature.
Describe the preferred embodiment of the present invention above in association with accompanying drawing in detail, but, the present invention is not limited to above-mentioned reality
Apply the detail in mode, in the range of the technology design of the present invention, multiple letters can be carried out to technical scheme
Monotropic type, these simple variant belong to protection scope of the present invention.
It is further to note that each particular technique feature described in above-mentioned specific embodiment, in not lance
In the case of shield, can be combined by any suitable means.In order to avoid unnecessary repetition, the present invention to various can
The compound mode of energy no longer separately illustrates.
Additionally, combination in any can also be carried out between the various different embodiment of the present invention, as long as it is without prejudice to this
The thought of invention, it equally should be considered as content disclosed in this invention.
