Abstract
The utility model discloses a forced spaced type heating and drying device of asphalt mixture mixing equipment. The heating and drying device comprises a drying box, an induced draft port, a feeding inlet, a discharging outlet and a heating device, wherein the induced draft port and the feeding inlet are located at the top of the box body of the drying box; the discharging outlet and the heating device are located at the lower part of the drying box body; and a net chain conveyor is arranged in the drying box body and receives cold aggregate falling from the feeding inlet. Compared with the prior art, the device can sufficiently utilize heat, so that the heat exchange efficiency is improved, the production of powder is reduced, powder and aggregate can be roughly separated, the dust amount can be reduced, and the discharge amount of powder of tail gas is further reduced.
Description
Technical field
The utility model belongs to the bituminous mixture blending equipment technical field, is specifically related to the heating, drying device that a kind of bituminous mixture blending equipment is dried for hot aggregate.
Background technology
Existing aggregate mainly relies on the horizontal rotary flash dryer to dry, and it relies on the stir-fry plate in cylinder that material is dug, and forms the material curtain in cylinder, and the hot air provided with firing equipment carries out interchange of heat, and then reaches 150 ℃-180 ℃, evaporates the moisture in material.It is large that this heating, drying mode exists energy consumption, and heat exchanger effectiveness is low, and noise is large, and dust is large.Also has another kind of tower drier in prior art, as May 27 2009 day for announcing, the disclosed tower drier of notification number CN201246946Y, by drying body of heater and flow distribution plate, form, described oven dry body of heater is vertical type, the some flow distribution plates of inboard wall of furnace body cross arrangement, described flow distribution plate is arranged on and dries on furnace wall in downward-sloping mode, and there is the shunting block of some projections on the flow distribution plate surface.Operating principle is to rely on the gravity of aggregate to make material from the downward landing in the upper end of drying oven, and the effect by the batch turning plate in the process fallen makes material form the material curtain, with the bottom firing equipment, carries out interchange of heat, thus the heating, drying material.Thereby this drying mode is material to carry out interchange of heat and dried in the process fallen, because the time that material falls is very of short duration, heat does not take full advantage of, and heat exchanger effectiveness is low.Flow distribution plate and material collision friction in addition, serious wear, noise, dust are also large.
Summary of the invention
The above-mentioned defect existed for solving prior art, the purpose of this utility model is to provide a kind of bituminous mixture blending equipment aggregate heating, drying device, can utilize fully heat, improves heat exchanger effectiveness, reduce the generation of powder, and powder and aggregate are carried out to crude separation.
For achieving the above object, the technical solution used in the present invention is: this pressure clearance type asphalt mixture mixing equipment heating, drying device, comprise the oven dry casing, be positioned at air-vent, the charging aperture of drying the casing top, be positioned at discharging opening and the heater of drying lower box, it is characterized in that: be provided with net chain conveyor in drying casing, described net chain conveyor is accepted the cold aggregate that charging aperture falls into.
Described net chain conveyor is a plurality of and upper and lower setting straggly, and the net chain conveyor of next stage is accepted the discharge end of upper level net chain conveyor.
Adopt the beneficial effect of technique scheme: this forces clearance type asphalt mixture mixing equipment heating, drying device by net chain conveyor, aggregate progressively to be transmitted to the net chain conveyor of its underpart from the top of drying baker, rely on quantity and the transporting velocity of net chain conveyor to adjust the aggregate drying course, water content for different aggregates is adjusted, heater by the drying baker bottom in the process transmitted carries out heating, drying to aggregate, because aggregate increases in the path of transmitting downwards, increased the heat time heating time of aggregate, thereby take full advantage of heat, heat exchanger effectiveness is high.When aggregate falls into net chain conveyor from charging aperture, add assorted powder in aggregate and directly fall from the chain hole of net chain conveyor, powder and aggregate are carried out to crude separation, aggregate dust in the process of heating is less.Compared with prior art, there is following advantage:
1, the aggregate that this heating, drying device is less for water content can adopt single net chain conveyor structure;
2, for water content, higher fines can adopt circulating-heating to dry, and avoids the drawback that once can not dry;
3, the aggregate whereabouts is contrary with direction of heat transfer, can more take full advantage of heat;
4, do not need to fry material, can reduce Dust Capacity, and then reduce dust in tail gas, can dwindle deduster.
Operating principle of the present utility model is as follows:
During work, by elevator, aggregate is risen to the charging aperture of drying casing top, and throw to net chain conveyor, along with the running of net chain conveyor, the aggregate on it falls on the adjacent next stage net chain conveyor in bottom, because adjacent net chain conveyor transports in opposite directions, material is carried back and forth in drying casing, heating, drying in conveying, stirring in the process of batch turning, the purpose that just can reach heating, drying when aggregate arrives bottom is transferred to next process.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
The front view that Fig. 1 is the utility model structure.
The top view that Fig. 2 is Fig. 1.
The specific embodiment
This shown in Fig. 1,2 forced clearance type asphalt mixture mixing equipment heating, drying device, comprises and dries casing 1, is positioned at air-vent 2, the charging aperture 4 of drying the casing top, is positioned at discharging opening and the heater of drying lower box.Heater is burner, burner is connected with the burner interface 6 of drying lower box, in drying casing 1, is provided with net chain conveyor 3, and charging aperture 4 connects the outlet of elevator 5, elevator 5 rises to aggregate the charging aperture 4 of drying casing 1 top, and aggregate is dropped down onto on net chain conveyor 3.Described net chain conveyor is a plurality of upper and lower settings straggly, and the net chain conveyor of next stage is accepted the discharge end of upper level net chain conveyor, and two adjacent net chain conveyors turn round in opposite directions, and aggregate is back and forth transported in the process of carrying downwards.
Claims (2)
1. a bituminous mixture blending equipment aggregate heating, drying device, comprise the oven dry casing, be positioned at air-vent, the charging aperture of drying the casing top, be positioned at discharging opening and the heater of drying lower box, it is characterized in that: be provided with net chain conveyor in drying casing, described net chain conveyor is accepted the cold aggregate that charging aperture falls into.
2. bituminous mixture blending equipment aggregate heating, drying device as claimed in claim 1, it is characterized in that: described net chain conveyor is a plurality of, and upper and lower setting straggly, the net chain conveyor of next stage is accepted the discharge end of upper level net chain conveyor.
