Abstract
The invention discloses a stirring-type heating bin for an asphalt mixture. The heating bin comprises a bin body, a stirring shaft and a heater, wherein the bin body is rectangular and provided with a bin door, and a discharging hole is formed in a lower end part of the bin body; the bin body adopts a dual-layer hollow structure and is provided with an outer wall and an inner wall, and a longitudinal arc structure is arranged at the bottom of the inner wall of the bin body; the stirring shaft is horizontally and longitudinally arranged in the bin body and provided with symmetrical rectangular frame type stirring blades; a plurality of heat air inlets are formed in the inner wall of the bin body, a smoke outlet is formed in an upper part of the bin body, and the heater is mounted between the outer wall and the inner wall at the bottom of the bin body. Hot gas generated by the heater is used for heating the inner wall of the bin body and indirectly the mixture in the bin; the hot gas enters the bin body and is fully mixed with the mixture under the rotational action of the blades of the stirring shaft; the blades of the stirring shaft also achieves an effect of turning over the mixture at the bottom of the bin body, so that local overheating of the mixture at the bottom of the bin body is prevented; the heating bin prolongs the contact time of the hot gas and the mixture, increases the heat utilization rate, and shortens the heating time.
Description
Technical field
The present invention relates to asphalt pavement conserving construction equipment field, particularly relate to a kind of stirring type asphalt storage bin capable of heating mixed material.
Background technology
When flexible pavement carries out routine servicing repairing, on-board type asphalt mixture storehouse is mostly adopted to carry out heating and thermal insulation feed, when particularly repairing in the winter time, the insulation of mixing station feed road is very difficult, and to be our daily Asphalt Pavement Damage repair in on-board type asphalt mixture storehouse provides convenience.Mainly drum-type and fixed two kinds of bituminous mixture storehouse in the market: drum-type compound feed bin adopts bottom-heated wall to heat cylinder, in the process of heating, the rotation of cylinder makes the bituminous mixture in cylinder obtain stirring, firing rate is fast, compound is heated evenly, but cylinder compound feed bin is once feeded and can not be exceeded 1/2nd of its volume, and charging capacity utilization is low, overall structure is more complicated in addition, safeguards that manufacturing cost is high; Fixed compound feed bin, adopts structure feed bin inside division being become multiple grid more, and to improve the contact area of bituminous mixture and inner barn wall, distribute in the bottom of warehouse multiple heater, carries out heating indirect heating bituminous mixture to inner barn wall.This kind of feed bin capacity utilization is high, can fill material, makes maintenance cost low, can once provide a large amount of bituminous mixtures, but due to heat conduction very slow, the heat time is very long, needs a few hours, can not carry out emergency first-aid repair feed.
Summary of the invention
Technical problem to be solved by this invention is to overcome prior art defect, provides a kind of stirring type asphalt storage bin capable of heating mixed material.By installing shaft in fixed feed bin inside, in the process of heating, bituminous mixture being overturn, making mixed material heating even, preventing hot-spot, thus accelerating firing rate, shortening the heat time.
In order to solve the problems of the technologies described above, stirring type asphalt storage bin capable of heating mixed material provided by the invention, comprises warehouse, shaft, heater; Described warehouse is rectangle, and feed bin door is established at warehouse top, and warehouse bottom is provided with discharging opening; It is characterized in that: described warehouse is double layer hollow structure, be divided into outer wall and inwall, is longitudinal arc-shaped structure bottom warehouse inwall; Shaft level is longitudinally arranged in warehouse, and described shaft is with symmetrical rectangular frame type agitation blades; Described warehouse inwall is provided with some heat air inlet ports, and smoke vent opening is established on warehouse top, and heater is arranged between outer wall bottom warehouse and inwall.The hot gas that heater produces can enter warehouse inside by heat air inlet port, and heat bituminous mixture, the waste gas after being utilized is discharged to out of my cabin by smoke vent opening, and the bituminous mixture heated is discharged from discharging opening.
As improvement, be two longitudinal arc structures bottom described warehouse inwall, two longitudinal circular arcs are parallel to each other; Shaft is equipped with above two arc structures.
Beneficial effect of the present invention is: the hot gas that heater of the present invention produces is heated the bituminous mixture in storehouse indirectly by warehouse inwall; In addition, the hot gas of generation is by heat air inlet port, and enter into warehouse inside, under the stirring action of shaft, hot gas mixes with bituminous mixture, plays the direct heat effect of bituminous mixture; The symmetrical rectangular frame type agitation blades of shaft, in the process stirred, also serves the effect overturn the bituminous mixture with warehouse contact internal walls simultaneously, prevents this part bituminous mixture hot-spot; Which adds chance and time that heat contacts with bituminous mixture, heat is fully utilized, saves fuel, shorten the heat time.

Detailed description of the invention
Below in conjunction with accompanying drawing, invention is elaborated.
As shown in Fig. 1 to 7, stirring type asphalt storage bin capable of heating mixed material provided by the invention, comprises warehouse 1, shaft 2, heater 3; Described warehouse 1 is rectangle, and gallery ports 5 are established at warehouse top, and warehouse 1 bottom is provided with discharging opening 11; Described gallery ports 5 are convertible double swing doors, can folding freely, can carry out upset and open time reinforced; Described warehouse 1 is double layer hollow structure, and be divided into outer wall 6 and inwall 7, warehouse outer wall 6 is made up of heat insulating material, is two longitudinal arc structures bottom warehouse inwall 7; Above two circular arcs, be equipped with shaft 2, shaft 2 is all with symmetrical rectangular frame type band sword agitation blades 2-1, and agitation blades 2-1 suits mutually with corresponding arc structure; It is inner that shaft 2 is arranged on warehouse 1 by corresponding bearing support 4, under the external force driving that power and transmission device provide, can rotate freely, reach the effect to the inner bituminous mixture uniform stirring of warehouse 1; Described warehouse inwall 7 is provided with some heat air inlet ports 8, smoke vent opening 9 is established on warehouse 1 top, and heater 3 is installed between outer wall 6 bottom warehouse 1 and inwall 7 by heater installing port 10.
Operationally, it is inner that bituminous mixture enters warehouse 1 by gallery ports 5 in the present invention; The hot gas that heater 3 produces heats warehouse inwall 7, indirectly the bituminous mixture in warehouse 1 is heated, hot gas can enter warehouse 1 inside by heat air inlet port 8 in addition, under agitation blades 2-1 turning effort on shaft 2, hot gas is fully mixed with bituminous mixture, the agitation blades 2-1 of shaft 2 also serves the inverting action of the bituminous mixture to warehouse 1 inner bottom part simultaneously, prevent bottom material hot-spot, which enhance the time of contact of hot gas and bituminous mixture, improve heat utilization efficiency, shorten the heat time.
Waste gas after being utilized is discharged to outside warehouse 1 by smoke vent opening 9, and the bituminous mixture heated is discharged from discharging opening 11.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
