Ingredient for additives for concrete or asphalt waste processing

The invention relates to a device for allocating a portion by portion liquid or meltable additive for concrete or asphalt mix processing »

Bituminous road building materials can contain additives in 3? Orms of adhesive can be added to improve the adhesion of the bitumen to the rock. As with the continuous mixing process If an uninterrupted bitumen flow is fed to the mixer, the adhesive must also be introduced evenly. "In many cases, however, such adhesives are at ambient temperature in a solid form, so that it is not easy to supply the adhesive continuously and in an equal amount.

The invention is based on the object of creating a device which is suitable for this task and which can accomplish the task with the simplest Medium »and with satisfactory accuracy and verifiability at all times.

The device according to the invention is characterized by an electrical. or with heating oil and by means of a thermostat controlled controller at a constant temperature level held torrate tank for liquefying the additive, as far as it is in solid form, and through a closed one, too Dosing device located in the boiler room for the batch delivery of the liquid or liquefied additive via an insulated one

Discharge line into the bitumen or water injection line.

As a metering device, a lifting device is expediently used limit screw adjustable sylis. the guided suction piston used.

The amount set by the stroke limiting screw can be read off an attached scale in ecm.

the quantity control of the dosed goods is in the Discharge line a three-way cock with connecting line built-in.

The following is an exemplary embodiment based on the drawing the invention explained in more detail and be

The storage tank 3 "containing the adhesive is by means of an arbitrarily designed heating device brought to a certain temperature level, which by a Thermostat 1 controlled attached glider 2 is maintained. The additive is therefore constantly in liquid IPorm kept. The metering device also protrudes into the boiler room 4 and absorbs a certain amount of liquid via the ball valve 10. The air-powered one Piston 8 then pushes the amount absorbed through the discharge line 5, which is insulated against heat dissipation, into the Bitumen or water injection line 6 «,

At one end of the suction piston 8 is a stroke limiting screw 7 provided, the stroke volume is set with the help of "selcher" can be. Located next to the stroke limiting screw 7 attached scale 11 allows a reading of the stroke volume in ecm.

The Srst adjustment of the scale 11 and the current later one tTo check the set quantities, is by interception of the measured additive via a Ureiwegehahn and a AnseVLußleitung 12 possible, which is built into the discharge line 5 is. The intercepted quantities are finally based on controlled by a separate scale »
