Description

Automatic filling device of molten mass

The present invention relates to automatic filling device of molten mass, this device by with the fused mass supply source with piping method bonded assembly infuser, the liquid of high temperature, high viscosity for example the fused mass of bitumen emulsion etc. automatically inject in the container of oil drum etc.

As everybody knows, always as follows: as on pillar, to set up an infuser as the device of filling bitumen emulsion in containers such as oil drum, this infuser has a lower end to be provided with the high low type injecting tube of nozzle, and setting-in upper and lower be free to slide, the valve piston that comes this nozzle of open and close from the inboard by valve rod in the injecting tube.Oil drum move to this infuser under, the fused mass gangway of oil drum is aimed at the nozzle of injecting tube, valve piston is risen nozzle is opened, from the outside of the fused mass gangway of oil drum bitumen emulsion is injected oil drum.

But have such problem with this device: because bitumen emulsion is to fall in it outside the fused mass gangway of containers such as oil drum, so its drop is very big, oil drum can vibrate when beginning to inject, and makes a noise simultaneously.Because inject with roughly the same flow with an infuser from start to finish, so when measuring the weight of injecting, be difficult to just in time stop definitely injecting when reaching predetermined weight, injection rate tends to erratic generation deviation again.

The object of the present invention is to provide a kind of automatic filling device of molten mass, vibration or noise can not take place in this device oil drum etc. at the beginning of injecting, and can stop definitely simultaneously injecting when reaching the variable of regulation, and can shorten the required time of injection.

Below the embodiment that present invention will be described in detail with reference to the accompanying.

This apparatus for automatically filling is by large and small two

infusers

infusers

1 and 2 vertical racks are located on the not shown pillar, provide bitumen emulsion by supplying with the person in charge 4 by the bitumen emulsion supply source.

Large and small two

infusers

1 and 2, two outer peripheral faces of injecting tube 1a that two diameter is different and 2a are set up in parallel with contacting with each other, and in each injecting

tube

1a and 2a, but easy on and off slidably setting-in valve piston 5 and 6.The size that large and small two injecting

tube

1a and 2a add up can be inserted the fused mass gangway 3a of oil drum 3.Large and small two valve pistons 5 are connected respectively with piston rod 9a, the 10a of a pair of

cylinder assembly

9 or 10 with 8 by valve rod 7 respectively with 6, and, in each injecting

tube

1a, 2a, open separately respectively or the nozzle 1b or the 2b of its lower end of closing by each

cylinder assembly

9 and 10 and can slide up and down individually.On valve rod 7 and valve piston 5, be provided with air hole 11, in the air hole 12 that also is provided with on valve rod 8 and the valve piston 6 till upper end to the lower surface central authorities of valve piston 6 of valve rod 8 from upper end to the lower surface central authorities of valve piston 5 of valve rod 7.Air is introduced into air hole 11,12 from air outside

flexible pipe

13,14, and can go out air from the lower surface central injection of

valve piston

5,6.

The injecting tube 1a of big infuser 1, its middle-end is connected with the front end of supplying with the person in charge 4, and the injecting tube 2a of little infuser 2, its middle-end is connected with the front end of the bypass pipe 4a that goes out from the leading section bifurcated of supplying with the person in charge 4, owing to connect like this, end forms inflow entrance 1c, 2c therein respectively.Supply with to be responsible for 4 be provided with electromagnetic flow control cock 15 midway, bitumen emulsion is supplied to two

infusers

1 and 2 by this flow control valve 15.

Below these two large and

small infusers

1,2, shown in the 4th figure, be provided with the lifter (for example desk-top lifter) 17 that carries oil drum 3 upper and lower liftings, this oil drum 3 is transported by infeed conveyor belt 16.This lifter 17 is provided with roll-type load-transfer device 18, also have simultaneously not shown, the known force transducer of the course setter of decision oil drum 3 positions and metering oil drum 3 weight.

Operating process to oil drum 3 filling bitumen emulsions is as follows: in the 4th figure (A), in a single day the oil drum of being sent here by infeed conveyor belt 16 3 is loaded on the lifter 17 that is positioned at lower position, this lifter 17 just rises, oil drum 3 is lifted, and two injecting

tube

1a, 2a just insert the fused mass gangway 3a of oil drum.At this moment, two

valve pistons

5,6 descend, and close nozzle 1b, 2b respectively.In a single day lifter 17 rises to specified height, just action of

cylinder assembly

9,10, and two

valve pistons

5,6 rise to the top of inflow entrance 1c, 2c, stop at the state shown in this figure (A).At this state, shown in this figure (B), flow control valve 15 is in roughly half-open state, and bitumen emulsion is injected in the oil drum 3 with little drop and low discharge by being inserted in two injecting

tube

1a, 2a in the oil drum 3.

In case injected the bitumen emulsion (for example timer only press setting-up time move) of required a small amount of (for example about 1/4 of predetermined weight) in the oil drum 3, shown in the 5th figure (A), then lifter 17 just drops to midway location, flow control valve 15 is opened shown in figure (B) fully, insert slightly under the state of fused mass gangway 3a at two injecting

tube

1a, 2a, bitumen emulsion is injected in the oil drum 3 with big flow through two injecting tube 1a, 2a.Meanwhile, on lifter 17, beginning is measured oil drum 3 by force transducer.

Reach the weight for example about 90% of regulation when the injection rate of bitumen emulsion, and during the pulse that has predicted by force transducer output expression, the cylinder assembly 9 of big infuser 1 one sides just carries out homing action, valve piston 5 descends while the bitumen emulsion of extruding in the big injecting tube 1a, in the lower position, shown in the 6th figure (A), close the nozzle 1b of big injecting tube 1a, such shown in this figure (B) simultaneously, flow control valve 15 becomes 2/3 closing state.Therefore, bitumen emulsion is only by little injecting tube 2a and to inject in the oil drum 3 than flow littler at the beginning of injecting.

When the injection rate of bitumen emulsion reaches predetermined weight, represent this pulse that reaches in case export by force transducer, the cylinder assembly 10 of then little infuser 2 one sides just carries out homing action, valve piston 6 descends while the bitumen emulsion of extruding in the little injecting tube 2a, in the lower position, shown in the 7th figure (A), close the nozzle 2b of little injecting tube 2a, simultaneously, flow control valve 15 is fully closed shown in this figure (B), and the injection of bitumen emulsion stops.Therefore, bitumen emulsion extremely injects the variation of the injection flow till finishing shown in the 10th figure from injecting beginning.

Then, shown in the 8th figure (A), (B), still close at flow control valve, nozzle 1b, the 2b of two injecting

tube

1a, 2a be still by under

valve piston

5,6 closing state, by the air hole 11,12 in two valve rods 7,8, the lower surface central authorities ejection of air from valve piston 5,6.These residual asphalt emulsions like this, also are blown in the oil drum 3, so can not fallen the outside of the oil drum of then being sent here and the oil drum of making dirty attached to the lower surface of

valve piston

5,6 and the residual asphalt emulsion on nozzle 1b, the 2b.

Like this, in a single day the bitumen emulsion of the predetermined weight of having packed in the oil drum 3, shown in the 9th figure, lifter 17 just descends, and two injecting

tube

1a, 2a are after the fused mass gangway 3a extraction of oil drum, and oil drum 3 is reprinted on the output load-transfer device 19 and is sent.

As mentioned above, following effect is arranged according to the present invention.

1. be set up in parallel large and small two injecting tubes, make their insert the fused mass gangway of the container of oil drum etc., drop is just little during injection, and with the flow of flow regulating valve regulation bitumen emulsion etc., available low discharge injects at the beginning of injecting, so vibration or noise can not take place for oil drum etc. at the beginning of injecting.

2. after having injected a small amount of required fused mass, can and be transferred to full-gear to flow control valve and inject, inject required time so can shorten by large and small two injecting tubes.

3. when being about to reach the charging quantity of regulation, can close the nozzle of big injecting tube, only be adjusted to throttle with little injecting tube and flow control valve, to inject than littler flow at the beginning of injecting, so can correctly measure, the deviation of injection rate reduces.
