Abstract

Be in the milk automatic sewage discharging device.There is the fixed funnel of slurry commanding tank and side in grouting pipeline, there is the overfall density bucket of thick liquid discharge mouth on top.Set up YE, the driving of its built-in motor actively, driven gear, driven gear shaft stretches out at gear-box outer end to be fixed by welding or connector with overfall density barrel tank floor.And YE is controlled with programmable controller, to drive overfall bucket to rotate set angle θ, by remaining overfall, automatic-discharging in funnel, realizes automatic pollution discharge from slurry commanding tank is emitted on.The existing artificial blowdown manually dialled decontamination water tube hose from overfall bucket and inserted in funnel is avoided, comprehensive pollution of the overfall on each device, ground is result in, substantially improves construction environment.Manpower is saved, able-bodied labour is removed and pollutes by force.And design limiting rotational angle theta rotation time, ensure that actuator turns power-off does not burn out YE.Design limiting gearratio minimum, ensures that overfall liquid is discharged in accurate location.Functional reliability is strong.Circulation line for power station grouting system.

Description

Be in the milk automatic sewage discharging device

(1) technical field

Present invention grouting automatic sewage discharging device, is related to equipment in the grouting system circulation loop in grouting works.Belong to physics Mixing arrangement class (B01F).

(2) background technology

Blowdown mode in existing grouting works, the grouting system circulation loop seen in Fig. 1, existing grouting works is along slurries Flow direction is typically provided:Slurry commanding tank 4, grouting pump 8, flowmeter 9, grout hole 10, pressure gauge 11, valve 12, overfall flowmeter 13rd, overfall density bucket 3.Overfall density bucket is by the thick liquid discharge mouth 3.1 of top overfall barrel top cover arm 3.2 by overfall in overfall density bucket Come in slurry commanding tank 4 (see Fig. 3, Fig. 4).As:Grouting pump extracts the slurries prepared in slurry commanding tank through grout hole pulp-inlet pipe out 10a sends into grout hole 10, is in the milk, while setting grout hole return pipe 10b again, overfall is drawn, then by pressure gauge 11, valve Door 12, overfall flowmeter 13, overfall density bucket 3, overfall come in slurry commanding tank, and serum recycle loop is formed with this, ensured Slurries do not solidify in grouting, smoothly fill slurries required in grout hole.But slurries are up to standard in the grout hole, There are remaining slurries in ordinary circumstance circulation loop in overfall density bucket, then need special one manually by overfall density bucket Pai wu flexible pipes 3.3 dial de- (3.3 see Fig. 1), from overfall density bucket and directly place Pai wu flexible pipes in construction ground or still blowdown In ditch.

Because existing control overfall row wu is completed, this mistake by the way that the flexible pipe for filling cement grout manually is changed into position Journey makes slurries in flexible pipe be filled with funnel, slurry commanding tank, overfall density bucket top surface, surrounding and ground, and full face wu has contaminated overfall with slurry Scene, and operator's self-pollution is big, labor intensity is big.

(3) content of the invention：

The grouting automatic sewage discharging device that the present invention is provided, its purpose is sought to solve in existing grouting works by artificial row Dirty labor intensity is big, efficiency is low, it is comprehensive pollution, environmental protection difference the problems such as.

Technical scheme is as follows:

Be in the milk automatic sewage discharging device, including:Grout hole 10, overfall density bucket 3 and top in grouting pipeline have thick liquid discharge mouth 3.1 overfall bucket top arm 3.2, slurry commanding tank 4 and the funnel 5 of side upper end fixation, the blow-off pipe 6 connected with funnel lower section, it is special Levying is：

1) set to drive 3 rotation set angle θ of the overfall density bucket YE 1 containing motor.2) motor Sequentially be connected the inner pinion gear 2.1 of gear-box 2, driven gear 2.2；Driven gear shaft 2.3 stretches out gear-box outer face 2.4 Place is connected and fixed on overfall density bucket tank floor by welding or connector 3.5.3) programmable controller 7 is set:YE Control signal wire 1.1 connects programmable controller execution circuit 7.1.4) the U-shaped overflow through hole 5A connected is set between slurry commanding tank and funnel.

The rotation time T of overfall density bucket correspondence rotation angle, θ is set in above-mentioned YE 1<10 seconds.

Gearratio is less than 6/9 between above-mentioned driving gear 2.1 and driven gear 2.2.

Beneficial effect of the present invention：

1) overfall density bucket is controlled to rotate set angle by YE, programmable controller, remaining overfall is automatic Funnel is emitted on Ji in Pai wu passages, realizing automatic pollution discharge.Exclude existing artificial blowdown, overfall is on each device, ground it is complete Face is polluted, and substantially improves construction environment.And manpower is saved, remove able-bodied labour and pollute work by force.2) company of setting between slurry commanding tank and funnel Logical U-shaped overflow through hole 5A:When the overfall water level of slurry commanding tank exceeds overflow lead to the hole site, then overfall it is automatic from overflow through hole arrange to Funnel is excluded by blow-off pipe.It can prevent high-order overfall from being overflowed from slurry commanding tank apical pore, full Mian wu dyes job site.3) because of design rotation The time T of angle, θ<10 seconds, that is, YE power-off time is limited, ensure not burn out electricity in the power-off time for performing rotation Device is controlled, reliable operation performance is strong.4) because design gearratio is zero or decreasing transmission ratio is less than 6/9, overfall barrel top cover arm is controlled 3.3 should not rotate too slow, ensure that satisfaction is not burnt out in YE power-off time, rotation angle, θ reaches setting value.Ensure back Slurries are discharged in accurate location.
