Abstract

A drying rotary drum provided with a regeneration ring mainly solves the problems that as a material hole for adding and recovering old material is not arranged, the existing rotary drum is not suitable for adding and recovering the old material. The drying rotary drum is characterized in that a plurality of material guide holes (7) are uniformly distributed in a drum body (1) corresponding to the circumference direction of the middle part of a heat-preservation copy plate (4), baffles (8) in the drum and baffles (10) outside the drum are respectively welded in the circumference directions inside and outside wall plates of the drum body (1) at the two sides of the material guide hole (7) and are vertical to the wall plates, a plurality of copy plates (9) outside the drum are arranged between the baffles (8) outside the drum, a plurality of copy plates (11) inside the drum are arranged between the baffles (8) inside the drum, the copy plates (9) outside the drum and the copy plates (11) inside the drum are arranged in an arc shape and are inclined to the same direction, and the inner side and the outer side of the material guide hole (7) are uniformly divided into a plurality of areas by taking the material guide hole (7) as the center. The drying rotary drum is provided with a recovered material guiding hole and can be added with new material and regenerate recovered material, thus realizing the functions of adding the recovered old material for equipment and drying and heating.

Description

A kind of drying roller with the regeneration ring

Technical field

The utility model relates to bituminous mixture stirring technique field, a kind of specifically drying roller with the regeneration ring.

Background technology

At present, the sandstone material that highway construction technology is used different size mostly by certain grating after the oven dry heated and stirred is mixed, the surface layer of making asphalt highway or basic unit.Along with the development of highway construction technology and the raising of asphalt-regenerating technology; Increasing recovery asphalt pavement material is used in the construction of the highway; Generally add about 30% till now from the old material adding proportion of initial 5% recovery and reclaim old material, the asphalt-regenerating technology has also experienced the process from the pre-test to the maturation.Now, the stirring adding technique of the renewable compound of pitch reaches its maturity: cold in place recycling, in-situ heat regeneration, the cold regeneration of plantmix, hot in-plant reclaimed.Wherein, the plant-mix heat recycle technology of drying heating through the old material of dram regeneration ring interpolation recovery is a new technology that is worthy to be popularized, and the main feature of this regeneration techniques is; Equipment is simple relatively; Fund input is low, and it is higher relatively to reclaim old material adding proportion, and production operation is easy to control; Adding technology is simple, reliable, suitable; Cost is low, remarkable in economical benefits.But present drying roller is only applicable to dry virgin material, does not add the entrance hole that reclaims old material, can only dry heating to new aggregate.

Summary of the invention

In order to overcome the deficiency that existing drying roller does not add the entrance hole that reclaims old material, inapplicable interpolation regeneration reclaimed materials; The utility model provides a kind of drying roller with the regeneration ring; The drying roller of this band regeneration ring has the reclaimed materials material guide hole, can add virgin material and regeneration reclaimed materials simultaneously.

The technical scheme of the utility model is: a kind of drying roller with the regeneration ring; Comprise cylindrical shell and inner insulation flight thereof; Corresponding insulation flight middle part circumferencial direction is uniformly distributed with several material guide holes on the described cylindrical shell; The cylindrical shell wallboard internal and external circumference direction of material guide hole both sides is welded with tube outer baffle, the tube Internal baffle perpendicular to wallboard respectively, and the outer flight of several tubes is arranged between the tube outer baffle, and flight in several tubes is arranged between the tube Internal baffle; The outer flight of described tube is circular-arc with the interior flight of tube and tilts to a direction, and it is several zones at center that both sides inside and outside the material guide hole are uniformly distributed with the material guide hole.

The utlity model has following beneficial effect: owing to take such scheme; Cylindrical shell is provided with material guide hole, and there are an interior flight and the outer flight of tube in both sides inside and outside the material guide hole, and interior flight of tube and the outer flight of tube be shape in the shape of a spiral; When cylinder is rotated counterclockwise; The regeneration reclaimed materials merges with virgin material in the tube after discharge hole for discharge in material guide hole gets into tube, and old material adds and the function of oven dry heating thereby realize reclaiming.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the sectional view along A-A among Fig. 1.

1-cylindrical shell among the figure, the long spiral plate of 2-, 3-promotes flight, and 4-is incubated flight, the 5-ring of regenerating, 6-discharging flight, 7-material guide hole, 8-tube outer baffle, the outer flight of 9-tube, flight in the 10-tube Internal baffle, 11-tube.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

By Fig. 1 and shown in Figure 2, a kind of drying roller with the regeneration ring comprises cylindrical shell 1; Cylindrical shell 1 inside has long spiral plate 2 from left to right successively, promotes flight 3, warming plate 4, discharging flight 6; Corresponding insulation flight 4 middle part circumferencial directions are uniformly distributed with several material guide holes 7 on the described cylindrical shell 1, and as preferably, material guide hole 7 is 15; Described material guide hole 7 is the rectangle along cylindrical shell 1 axis direction; Internal and external circumference direction on cylindrical shell 1 wallboard of the material guide hole 7 minor face left and right sides is welded with an outer baffle 8, tube Internal baffle 10 respectively, and described tube outer baffle 8, tube Internal baffle 10 have the outer flight 9 of several tubes perpendicular to wallboard between the tube outer baffle 8; Flight 11 in several tubes is arranged between the tube Internal baffle 10; The outer flight 9 of described tube is circular-arc with the interior flight 11 of tube and tilts to a direction, forms helical form, and it is several zones at center that material guide hole 7 inside and outside both sides are uniformly distributed with material guide hole 7.A flight 11 forms regeneration jointly and encircles 5, the charging that is used to reclaim old material in tube outer baffle 8, tube Internal baffle 10 and the outer flight of tube 9, the tube in material guide hole 7 both sides.

New aggregate is mentioned the back from falling through promoting flight 3 after long spiral plate 2 gets in the cylinder, in high-temperature flue gas, form equal refining curtain; Rely on burning hot gas to its oven dry, dehydration, intensification, radiation area mainly is made up of insulation flight 4, and heating reaches set point of temperature; Completion is to dehydration, oven dry, the heating process of building stones; Reclaim old material and be input in the tube,, push aggregate to discharging opening by discharging flight 6 at last with virgin material interchange of heat and fusion through regeneration ring 5.
