CS205371B1 - Apparatus for dilition till 200 degree warm asphalt-mastic mixtures for pipeline transpotration - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for injecting asphalttomastix compositions for conveying by pipeline containing up to 80% solid abrasive particles up to 200 ° C.

Previously known devices, ie pumps, can convey mixtures containing scrubbing particles up to a wax temperature. 80 ° C. These are pumps for concrete and mortar mixtures. Pumps, which can operate at higher temperatures, i.e. up to 200 ° C, are capable of delivering only liquid solutions without scouring particles. In the pump type allowing the delivery of the above mixture, which obtains compressed energy by alternately pressing special hoses by rotating the cylinders in the rotary chamber, these hoses often break down due to wear, increasing operating costs.

The aforementioned disadvantages are overcome by a device for the aging of up to 200 ° C of the hot asphalomastix mixtures according to the invention, which consists in that the pressure screw for removing the dense mixture from the hopper opens into a mixing vessel provided with a rotating mixture agitator. a mixing nozzle is provided for injecting a measured amount of bitumen, and at the top of the vessel is a conduit for discharging the diluted mixture.

The use of this device results in reduced operating costs due to reduced hose wear and thus higher operational safety.

The device consists of a chamber 1 with a hopper 4 » ⁷ whose bottom part is provided with a pressure screw 2 which opens into a mixing vessel equipped with a mixing screw 6, a hot resin injection nozzle J and a discharge line 8. The pressure screw 2 and mixing screw 6 are driven by a motor 2 via gears. The direction of rotation and pitch of the auger of the mixing screw are chosen to assist the extrusion of the mixture into the discharge line> 8.

The apparatus utilizes a mixture of hot bitumen and aggregates for decreasing the resistance of the asphalomastix mixture through a decreasing resistance line as the percentage of hot bitumen in the mixture increases.

In the asphalomastix mixture, the ratio of bitumen to aggregate is such that the necessary screw pressure in the pipeline could not be achieved by the pressure screw. Therefore, the hopper 4 of the device fills the resin and aggregate mixture with salmon, allowing the pressure screw 2 in the chamber 1 to sufficiently compact the mixture and press it into the connecting tube between the chamber 2 ^{and the} mixing vessel. toward the mixing vessel where the pressurized semi-dry mixture is disassembled by the mixing screw 6 and mixed with a measured amount of hot resin injected through the nozzle J into the mixing vessel, and the diluted asphalttomastix mixture is subsequently extruded into the conveying line.
