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.Electric Actuator is added, built-in motor driving active, driven gear, driven gear shaft is stretched out at gear-box outer end to be fixed by welding or connector with overfall density bucket tank floor.And Electric Actuator is controlled with programmable controller, overfall bucket to be driven to rotate set angle θ, remaining overfall in funnel, is realized into automatic pollution discharge from automatic-discharging in slurry commanding tank is emitted on.Avoid it is existing manually from overfall bucket dial decontamination water tube hose and be inserted into the artificial blowdown in funnel, result in comprehensive pollution of the overfall on each device, ground, substantially improve construction environment.Manpower is saved, removal able-bodied labour pollutes by force.And design limiting rotational angle theta rotation time, ensure that actuator turns power-off does not burn out Electric Actuator.Design limiting gearratio minimum ensures that overfall liquid is discharged in accurate location.Functional reliability is strong.For the circulation line of power station grouting system.

Description

Be in the milk automatic sewage discharging device

(1) technical field

The utility model grouting automatic sewage discharging device, is related to equipment in the grouting system circulation loop in grouting works.Belong to Physical mixed device class (B01F).

(2) background technology

Blowdown mode in existing grouting works, is shown in Fig. 1, and the grouting system circulation loop in 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 It comes in slurry commanding tank 4 (see Fig. 3, Fig. 4).As:Grouting pump is by slurries extraction prepared in slurry commanding tank through grout hole inlet pipe 10a be sent into grout hole 10, be in the milk, while set grout hole return pipe 10b again, overfall drawn, using pressure gauge 11, Valve 12, overfall density bucket 3, comes overfall in slurry commanding tank, and form serum recycle circuit with this overfall flowmeter 13, protects Card slurries do not solidify in grouting, smoothly fill slurries required in grout hole.But work as slurries in grout hole and reached It marks, also has remaining slurries in ordinary circumstance circulation loop in overfall density bucket, then need special one manually by overfall density The blowdown hose 3.3 of bucket dials de- (3.3 see Fig. 1) from overfall density bucket, blowdown hose is directly placed in construction ground or still In sewage ditch.

Since existing control overfall blowdown is completed by the way that the hose for filling cement grout manually is converted position, this mistake Journey makes slurries in hose be filled on funnel, slurry commanding tank, overfall density bucket top surface, surrounding and ground, polluted overfall with slurry comprehensively Scene, and operator's self-pollution is big, labor intensity is big.

(3) invention content：

Grouting automatic sewage discharging device provided by the utility model, purpose seek to solve to rely on people in existing grouting works Work blowdown labor intensity is big, efficiency is low, comprehensive the problems such as polluting, is environmentally friendly poor.

Technical solution is as follows:

Be in the milk automatic sewage discharging device, including:There is thick liquid discharge mouth on grout hole 10, overfall density bucket 3 and top in grouting pipeline 3.1 overfall bucket top arm 3.2, the fixed funnel 5 of slurry commanding tank 4 and side upper end, the blow-off pipe 6 with connect below funnel, spy Sign is：

1) set to drive the Electric Actuator 1 containing motor of 3 rotation set angle θ of overfall density bucket.Electronic execution Device 1 is the rotating using driving source motor 1.2, and in the case where controlling signal function, realizes the angle, θ or structure that component needs rotate Part needs mobile distance.That realizes angle needed for component rotation is known as electric angle stroke actuator.Because Electric Actuator 1 is one Kind commercial product, basic function, principle, structure can be fully apparent from finding and choosing in open Baidu, and I will not elaborate. The rotation time T that overfall density bucket corresponds to rotation angle, θ is set in Electric Actuator 1<10 seconds.2) motor is sequentially sequentially connected 2 inner pinion gear 2.1 of gear-box, driven gear 2.2；Gearratio is less than 6/9 between driving gear 2.1 and driven gear 2.2.It is driven Gear shaft 2.3 is stretched out at gear-box outer end face 2.4 is connected and fixed on overfall density bucket babinet bottom by welding or connector 3.5 Face.3) programmable controller 7 is set:Electric Actuator control signal wire 1.1 connects programmable controller execution circuit 7.1.4) slurry commanding tank with The U-shaped overflow through-hole 5A of connection is set between funnel.

The utility model advantageous effect：

1) overfall density bucket is controlled to rotate set angle by Electric Actuator, programmable controller, remaining overfall is automatic It is emitted in funnel and drain outlet, realizes 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, removal able-bodied labour pollutes by force work.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 automatically 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, pollute construction site comprehensively.3) because designing rotation The time T of angle, θ<10 seconds, that is, Electric Actuator 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 decreasing transmission ratio is less than 6/9, control overfall barrel top cover arm 3.3 not rotate It is too slow, ensure that satisfaction is not burnt out in Electric Actuator power-off time, rotation angle, θ reaches setting value.Ensure overfall liquid accurate It discharges position.
