Embodiment 1
The utility model provides a kind of asphalt-regenerating system, referring to Fig. 1, this system comprises screening plant, regenerating unit 4 and exhaust gas processing device 5, wherein regenerating unit 4 has reative cell 41, the bitumen feed bucket 42 being communicated with reative cell 41, the additive feed hopper 43 being communicated with reative cell 41 and stack 44, stack 44 is communicated with above-mentioned exhaust gas processing device 5, make discarding in reative cell enter exhaust gas processing device along stack, also be appreciated that thus, one end of stack is communicated with reative cell, and the other end is communicated with exhaust gas processing device.In addition, in reative cell 41, there is heater and agitator, for improving the efficiency of asphalt-regenerating.While being appreciated that screening plant, for material screening (for convenience of description, " material " that below occur unless stated otherwise, all refers to pitch), have discharging opening, for the good material of exclude filter, this discharging opening is communicated with the bitumen feed bucket of regenerating unit.The concrete form being communicated with as for discharging opening bitumen feed bucket, will illustrate below.
For convenient, understand, the process that the old pitch of take is regenerated by said system is example, illustrate, old pitch is put into screening plant, pitch after screening enters the reative cell 41 of regenerating unit 4 by bitumen feed bucket 42, and for example comprise catalyzer to additive feed hopper 43 interior interpolation, for the additive of auxiliary old asphalt-regenerating.Meanwhile, heater is started working, and reative cell 41 is heated, and agitator stirs the old pitch in reative cell 41 and additive, to improve the efficiency of asphalt-regenerating.Waste gas in reative cell 41 enters treating apparatus by a definite date by stack 44, after purified treatment, discharges again.
The utility model can directly be used waste asphalt regeneration after screening to form operable pitch, reclaim and use old pitch, can be for aspects such as laying roads after it is regenerated, reduced cost, simultaneously, the utlity model has exhaust gas processing device, meeting under the prerequisite of old asphalt-regenerating, reduced the harm to environment in asphalt-regenerating process.
On bitumen feed bucket 42 and additive feed hopper 43, be respectively arranged with weighing device, this weighing device can be to claim, certainly, for example when additive is liquid, also can use traffic meter as weighing device.
Optionally, above-mentioned screening plant has primary dcreening operation bucket 1, and for Preliminary screening material, certainly, this material can refer to old pitch.Screening plant also comprises mill 3 and conveying device 2, and conveying device 2 is communicated with the screening outlet 11 of primary dcreening operation bucket 1 and the import of mill 3.Material after 1 screening of primary dcreening operation bucket flows out from screening outlet 11, falls in conveying device 2, and conveying device 2 is transported to the material after primary dcreening operation the import of mill 3.In mill 3, material is further ground into more tiny particle, to improve its reaction efficiency when the subsequent regeneration.Above-mentioned conveying device 2 can be belt conveyer, and this is optional embodiment certainly, and other conveyer also can be for the utility model.
Mill 3 has the outlet of grinding 31, after grinding, material discharges from grinding outlet 31, this grinds outlet 31 height higher than bitumen feed bucket 42 in level height, and grind outlet 31 and aim at bitumen feed bucket 42, therefore, from grinding the material of outlet 31 discharges, can directly drop into bitumen feed bucket 42.This grinding outlet 31 is the discharging opening of above-mentioned screening plant.
Optionally, one deck vibration screen is at least set in primary dcreening operation bucket 1, for by the material interception of bulk, prevents that the material of bulk from damaging mill 3.The net footpath of vibration screen is between 10-30mm, and certainly, this is optional scheme, and other net footpath goes for the utility model equally.Optionally, vibration screen can arrange three layers, and net footpath from top to bottom reduces successively, and as from top to bottom, the net footpath of first floor vibration screen is 30mm, and the second layer is 20mm, and the 3rd layer is 10mm.Certainly, three layers is optional scheme, is not limited to the utility model, uses three layers, and screen cloth net footpath successively successively decreases, and is in order to play better screening effect, guarantees the screening effeciency at primary dcreening operation bucket.
Embodiment 2
Compare with embodiment 1, in the present embodiment, between primary dcreening operation bucket 1 and mill 3, do not need conveying device, and grind outlet 31 rear use transfer equipments by mass transport to bitumen feed bucket 42, other side is all identical with embodiment 1, concrete, as shown in Figure 2:
Primary dcreening operation bucket 1 be arranged on mill 3 directly over, screening outlet 11 imports over against mill 3, the material after 1 screening of primary dcreening operation bucket directly falls into the import of mill 3, or between screening outlet 11 and the import of mill 3, pipeline is set, and prevents material spilling.This set-up mode that is directly fallen into mill 3 by screening outlet, the consume that may strengthen mill 3.Certainly, no matter embodiment 1 or embodiment 2 are to grind in order to make to enter mill 3 through the material after the screening of primary dcreening operation bucket.
Height than the height of 3 outlets of mill in embodiment 1 higher than bitumen feed bucket 42, in the present embodiment, grind outlet 31 positions and be not restricted, can grind outlet 31 rear interpolation transfer equipments, this transfer equipment can include but not limited to it is the pump housing, conveyer belt.Shown in Fig. 2 is the transfer equipment with the pump housing 61 and carrier pipe 62 structures, and under the effect of the pump housing 61, material can enter bitumen feed bucket along carrier pipe 62.That is, by carrier pipe, be communicated with and grind outlet and bitumen feed bucket, by the pump housing, drive the material of discharging from grinding outlet, make this material state carrier pipe and enter bitumen feed bucket.In the present embodiment, the setting position of mill is comparatively flexible.
Should be appreciated that, in above-mentioned two embodiment, pitch, after the interior regeneration of reative cell 41, can directly be used, and for example, for laying road, corresponding opening also can be set on reative cell for taking out the pitch of regeneration.
In addition, above-mentioned two embodiments also can combine, for example, between primary dcreening operation bucket and mill, by conveying device, be communicated with, and grind outlet and adopt the mode in embodiment 2, by carrier pipe, are communicated with and are ground outlet and bitumen feed bucket, by the pump housing, drive material movement.
Finally it should be noted that: although described above the utility model and advantage thereof in detail, be to be understood that in the situation that do not exceed the spirit and scope of the present utility model that limited by appended claim and can carry out various changes, alternative and conversion.And scope of the present utility model is not limited only to the specific embodiment of the described process of manual, equipment, means, method and step.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, according to the utility model, can use and carries out with the essentially identical function of corresponding embodiment described herein or obtain process, equipment, means, method or step result essentially identical with it, that existing and will be developed future.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
