Preferably, be provided with the contraction awl that band protrudes into the narrow openings in the described chamber in the downstream of low-pressure cavity.
Preferably, the ice inlet is associated with the hopper that is placed on its top.
Preferably, described hopper has the shower water spout, moves to the ice inlet therein with auxiliary ice.
Another kind, this device can comprise the ice inlet that acutangulates horizontal expansion from described shell with respect to the longitudinal axis of shell.Preferably, this inlet is accepted on-cycle ice.
Preferably, this device also comprises the feedback line between low-pressure cavity and the ice/water out.
Preferably, the tap water water pipe penetrates into circulation ice inlet, thereby puts on the input flexible pipe that is connected on the circulation ice inlet.
This paper also discloses a kind of ice delivery system, comprise above disclosed jet dredge pump device, upwards reach to the water pump of pumps water inlet delivery cycle water, from discharging opening have the discharging pipeline of the water dish of the grid that separates from the ice of discharging pipeline and water, from stretch near the described grid needs go out to ice flexible pipe, from water dish stretch to hydraulic accumulator in order to the cold-water return pipe of this hydraulic accumulator conveying cold water and from this hydraulic accumulator stretch to water pump with to the pump chargine line of delivery cycle water.
Preferably, the pump chargine line has the filter that extend in the hydraulic accumulator, makes not inspiration ice.
Preferably, described need the place be the cement concrete mixer.
Description of drawings
Below by way of example with reference to description of drawings the preferred embodiments of the present invention, in the accompanying drawing:
Fig. 1 is the front elevational schematic of the first ice delivery system,
Fig. 2 is the front elevational schematic of another ice delivery system,
Fig. 3 is the front elevational schematic of jet dredge pump,
Fig. 4 is the schematic cross-section of jet dredge pump shown in Figure 3,
Fig. 5 is the scheme drawing of another kind of jet dredge pump, and
Fig. 6 is the schematic cross-section of jet dredge pump shown in Figure 5.
The specific embodiment
Schematically described ice delivery system 10 in the accompanying drawing among Fig. 1.System 10 comprises jet dredge pump 17, receives ice 24 from hopper 11.To grid 22 pumping ice and water, described grid 22 bends towards out ice flexible pipe 23 downwards to this jet dredge pump 17 along discharging pipeline 19, through this flexible pipe at 26 places ice deliver to such as cement concrete mixer (not shown) need the place.
As shown in Figure 2, another kind of pump 17` comprises the ice input flexible pipe 38 that reaches jet dredge pump 17 from hydraulic accumulator 15.This flexible pipe 38 is connected with inlet (also being marked with 38) shown in Figure 6.Embodiment shown in Figure 2 does not comprise hopper.
Tap water supply pipeline 37 comprises ball valve 16 and penetrates circulating water inlet 38 pipelines 37 to system water supply.This water follows ring ice chargine line 38 and is downward through and flows to hydraulic accumulator 15, perhaps directly is drawn into jet dredge pump 17, and this depends on that whether pump 12 is in running.
Fig. 3 and Fig. 4 show the inside of first jet dredge pump 17 and details on every side better.It comprises entrance 19, and entrance 19 is connected to the chargine line of High-Pressure Water.Jet dredge pump 17 also comprises nozzle 35 and low-pressure cavity section 33.What be connected to low-pressure cavity section 33 is one narrow section 32.Current are blocked in isocon highway section 30, and improve hydraulic pressure to overcome manometric head at 30 places.The discharging pipeline just is being connected on the discharging opening 31 below the shunting section 30.These sections comprise bolt flange interface as shown in the figure, with bolt these sections are linked together in addition packing ring or O-ring seals 42 between each adjacent flange-interface by flange-interface.
Narrow line branching in section 35 advances in the low-pressure cavity 33 of adjacent segment.This low-pressure cavity 33 is held hopper outlet 36, as shown in Figure 3.Hopper 11 is included in its upper periphery and stretches into wherein water spout 29 downwards, and these water spouts 29 are accepted water from pump 12 downstreams through ball valve 25.Like this, help ice cube 24 to move into low-pressure cavity 33 through hopper outlet 36.
In the embodiment of Fig. 5 and 6, be replaced in hopper, low-pressure cavity 33 comprises circulation ice inlet 38.Inlet 38 vertically acutangulates extension with respect to jet dredge pump, and this represents clearlyer at Fig. 6.
The current of high pressure low velocity are discharged through nozzle 35.Current quicken at jet pipe 35 places, convert high-speed current at the low pressure place.Low pressure produces in chamber 33 sucks power.
In Fig. 5 and use embodiment illustrated in fig. 6, open ball valve 16 and allow tap water flow to hydraulic accumulator 15 through circulation ice input flexible pipe 38 from pipeline 37.Hydraulic accumulator 15 abundances just the ice of fragmentation is joined in the hydraulic accumulator 15 behind the water, can primer pump 12 to carry high pressure waters to jet dredge pump 17.The order that starts is unimportant, because any excessive water all reclaims circulation, rather than is delivered to the cement concrete mixer.Current are through nozzle 35 and narrow 22, with at a high speed, low-pressure delivery, in chamber 33, cause low pressure.The pressure that current cause in chamber 33 causes the power of sucking through circulation ice inlet 38 in the chamber.Ice in hydraulic accumulator 15 is drawn into low-pressure cavity through flexible pipe/mouth 38.Water and ice stream are through narrow section 32.Water and ice expand at branch line 30.Pressure in the discharging pipeline 30 is very high, thereby is enough to ice and water transport are delivered to the high water head position, such as the top at the cement concrete mixer.As mentioned before, stride behind grid 22 the cement concrete mixer in the ice, and water flows through grid and enters water dish 28 at 21 places, return hydraulic accumulator 15 through pipeline 20 thus and utilize again.
Fig. 3 is extremely identical with use embodiment illustrated in fig. 4, but broken ice just is placed in the hopper 11 and ball valve 25 is open, to help ice shift-in low-pressure cavity.
Above-described device manufacturing cost is not high, simple to operate, and owing to no longer needs the people that the ice that becomes bag is transported to opening in ground number meter high cement concrete mixer, so the efficiency height.
