Problems solved by technology

Since the milling material after heating will have greater viscosity and asphalt smoke, the use of chutes in a large area will easily cause chute blockage, and the segregation problem will be further aggravated; if a belt conveyor is used, a large amount of smoke will leak out, causing environmental pollution. Pollution
At the same time, in order to avoid blockage, the chute feeding usually increases the chute angle, which increases the overall height of the equipment and makes it difficult to install the equipment; belt feeding has problems such as high temperature aging and temperature loss of the mixture.
Third, the addition of regenerants in traditional asphalt plant mixing heat regeneration equipment is generally set on the original machine mixing tank, and the regenerants are mixed with new and old materials at the same time when spraying, causing unnecessary waste

Abstract

The invention provides a continuous asphalt plant-mixing thermal regeneration mixture pre-mixing machine. The pre-agitation is carried out on a heated milled and planed material; meanwhile, a regenerator is added into the milled and planed material subjected to the pre-agitation; afterwards, an obtained substance is conveyed to a mixing cylinder of an original producing machine to be mixed with a new material. The continuous asphalt plant-mixing thermal regeneration mixture pre-mixing machine comprises a pre-mixing machine main body, an agitating device, a driving device and a regenerator spraying device, wherein the pre-mixing machine main body comprises a supporting seat and an agitating cylinder located on the supporting seat; the agitating cylinder is provided with a cover plate, a feeding hole and a discharge hole; the agitating device comprises two agitating shafts; the agitating shafts are connected with the driving device; the agitating shafts are provided with multiple agitating arms in the axial direction; the agitating arms are provided with agitating teeth; the regenerator spraying device is located at the top of the agitating cylinder.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to the design of a continuous asphalt plant mixing hot recycled mixture premixer. Background technique [0002] Asphalt plant mixing heat regeneration technology is to recycle the old asphalt concrete pavement surface layer through excavation or milling to the mixing plant, and carry out pretreatment such as crushing and screening as required, and then mix a certain proportion of new aggregate, New asphalt, regenerant, etc., are heated and mixed with special recycled asphalt concrete mixing equipment, and then transported to the construction site for paving to form a new asphalt concrete pavement structure layer with certain road performance. Since the factory mixed hot recycled asphalt milling material has the characteristics of low density, miscellaneous components, and easy bonding, the transportation and mixing of the recycled asphalt milling material n...
