Description
Technical field
The present invention relates to a kind of cylinder of drying simultaneously the heating recovery material and newly gathering materials, belong to hot in-plant reclaimed mixture equipment manufacturing technology field.
Background technology
Flexible pavement can produce disease and reduce pavement performance, thereby affect Vehicle Driving Cycle, so flexible pavement need to often carry out protect and repair after using certain hour.The road surface can produce a large amount of waste materials through digging in the protect and repair process, and these waste materials still have very high value as asphalt pavement material, as it is passed into disuse, just cause the material resources significant wastage, simultaneously ecological environment are polluted.
Studies show that, plant-mix heat recycle technology is most widely used general and the most ripe regeneration techniques, has good compliance, is applicable to the damaged condition of all kinds of asphalt surface courses.Plant-mix heat recycle technology be exactly with reclaimed materials with newly gather materials, new bituminous material, regenerative agent and other materials be through strict mix-design, produces hot regenerating mixture with plant mix equipment.This hot regenerating mixture can guarantee that technical indicator is not less than newly the gather materials bituminous mixture of the system of mixing of whole uses, and pavement performance satisfies the instructions for use of high class pavement; And, both can utilize again surfacing of former road obsolete material, also can with being used for Other Engineering after the salvage material regeneration, can be effectively used to the regeneration on old asphalt concrete road surface under the various conditions.At present, most of asphalt concrete regeneration equipments adopt two oven dry heated rollers of configuration, and one is used for the oven dry heating and newly gathers materials, and makes the moisture content bone dry in newly gathering materials and is heated to certain high temperature.One is used for drying the heating recovery material, makes the moisture content bone dry in the reclaimed materials and is heated to certain high temperature.Send into main frame through metering, carry out mix with new building stones, new pitch, stone flour.The problem that above-mentioned drying roller exists is: the cylinder of oven dry heating recovery material the sizing problem can occur in process of production; Each cylinder has cover heating flame system and a drive system, and the cylinder of oven dry heating recovery material also must take measures to avoid flame directly to contact reclaimed materials in case the ageing of asphalt in the non-return rewinding.Therefore this device structure is complicated, and manufacturing cost is high.
With the immediate prior art of the present invention be: the disclosed a kind of plantmix of Chinese utility model notice of authorization CN 202809439 U reclaimed the asphalt pavement material drying roller on 03 20th, 2013, at the even staggered radial reinforced rib plate that is fixed with of the inwall of drying roller, all welding is fixedly mounted with the shaft orientation reinforcing rib plate on this radial reinforced rib plate, all be fixedly mounted with the pectination lifting blade at this shaft orientation reinforcing rib plate upper surface, this pectination lifting blade is made of many broach and is equivalent to the stirring blade.This drying roller only solves the sizing problem in the existing plantmix reclaimed materials manufacturing process, does not solve the problem that prevents the ageing of asphalt in the reclaimed materials.
Summary of the invention
Main purpose of the present invention is to remedy the deficiencies in the prior art, a kind of cylinder of drying simultaneously the heating recovery material and newly gathering materials is provided, adopt a cylinder to dry simultaneously the heating recovery material and newly gather materials, the method that replaces two cylinder heating, dryings, both can prevent the ageing of asphalt in the reclaimed materials, make again work simplification, reduced the device fabrication cost.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of cylinder of drying simultaneously the heating recovery material and newly gathering materials comprises a cylinder, and the end face of cylinder one end has burner, and smoke box is established in the termination of the other end; To one section cylinder of smoke box, order arranges newly gather materials oven dry heating region and reclaimed materials oven dry heating region at burner; The inwall of two oven dry heating regions is laid completely the stirring blade; The import of newly gathering materials is arranged on high position, heated roller stage casing, and the outlet of newly gathering materials is arranged on cylinder by burner one end downside; The reclaimed materials import is arranged on an end high position of smoke box, and passes the straight-through reclaimed materials oven dry of smoke box heating region, and the reclaimed materials outlet is arranged on heating and drying roller stage casing downside, and with the outlet homonymy that newly gathers materials; On the boundary cross section of two oven dry heating regions, establish the burden-guiding cone of hollow by the oven dry heating region direction of newly gathering materials, establish the backgauge cone of hollow by reclaimed materials oven dry heating region direction; The axis of cylinder is mounted to and the horizon α that forms an angle, and makes the position of reclaimed materials oven dry heating region be higher than the oven dry heating region that newly gathers materials.
Above-mentioned angle α size is 3-5 °.
The present invention's advantage and beneficial effect compared with the prior art is:
1, oven dry heated roller of the present invention only has one, through oven dry heating internal construction being carried out Creative Design, arrange newly gather materials oven dry heating region and reclaimed materials oven dry heating region; The inwall of two oven dry heating regions is laid completely the stirring blade; In the oven dry heating region that newly gathers materials, the stirring blade stirs the material curtain that gathers materials and forms during by drum rotating, has realized that obstruct flame directly enters reclaimed materials oven dry heating region, prevent pitch composition in the reclaimed materials aging with manufacturing process in produce sizing.Owing to adopting a cylinder, the oven dry heating of reclaimed materials can rely on the high-temperature flue gas realization of coming from the oven dry heating region that newly gathers materials; Reduced by an oven dry heated roller, comprised cover heating flame system and a drive system;
2, the axis of cylinder of the present invention is mounted to and the horizon α that forms an angle, and makes the position of reclaimed materials oven dry heating region be higher than the oven dry heating region that newly gathers materials.Thereby realize when cylinder rotates, forming material curtain and material flowing to the discharging opening direction by the stirring blade; The present invention also utilizes burden-guiding cone and the backgauge cone that is arranged in the cylinder middle part, and can prevent from newly gathering materials has the situation of mixing to occur in cylinder with reclaimed materials;
3, scientific structure design of the present invention is reasonable, has simple in structurely, simple for production, and the advantage such as heating, drying is effective, and product cost is low can be used in plantmix's bitumen regeneration equipment.
