Abstract
The invention belongs to the field of a heating regeneration equipment for old asphalt mixed materials. The invention discloses a reversed far infrared and flame mixing heating-typed drying cylinder and comprises a refrigerant groove, a cylinder body and a blowtank; the refrigerant groove is arranged below one end of the cylinder body horizontally and the blowtank is arranged below the other end of the cylinder body horizontally; the cylinder body is provided with at least two rolling circles along the radial direction; a far infrared generation device is arranged in another end of the cylinder body below the blowtank and the far infrared generation device covers the fire spraying port of a flame generation device. In the technical proposal of the invention, as the far infrared generation device covers most of the flame of the flame generation device, the invention avoids the generation of high temperature due to the direct contact between the asphalt and the flame, therefore, the aging of the asphalt is avoided effectively and poisonous gas can not be produced; moreover, the flame is adopted as the power source of the far infrared generation device to produce the required infrared ray to reduce the loss of heat, so the higher utilization rate of heat energy is achieved.
Description
One, technical field
The present invention relates to a kind of thermal regeneration equipment of old asphalt mixture, particularly a kind of drying plant that utilizes far infrared and flame Hybrid Heating old asphalt mixture.
Two, background technology
Prior art: along with the development of highway in China, the bituminous paving highway that is open to the traffic has in early days been entered the overhaul curing period, milling goes out a large amount of old asphalt mixtures, environment is easy to cause bigger pollution, so the utilization again of waste asphalt mixture has caused concern widely.At present old asphalt mixture is carried out heating recovery when utilizing, can produce a large amount of bitumen flue gas and toxic gas.In order to address this problem, people have designed special drying and burner to the batch (-type) mixing apparatus, entire equipment comprises flame generating means 7, secondary air device 8, on cylindrical shell 11, be provided with charging aperture 9 and discharging opening 10, also be provided with dust arrester interface 12 in addition, around the burner opening of flame generating means 7, install secondary air device 8 additional, guarantee that the flame of burner combustion is elongated shape, and, make the pitch in the old reclaimed materials not aging not to the periphery diffusion.So, the heat energy utilization rate that burner produced is extremely low, and a large amount of heat energy are drained by air-introduced machine, has caused the significant wastage of the energy.
Three, summary of the invention
The present invention is directed to above-mentioned technical problem, a kind of saving energy is provided, reverse-flow far infrared and flame dual heating type drying barrel that the thermal efficiency is high.
Technical solution of the present invention is: a kind of reverse-flow far infrared and flame dual heating type drying barrel, comprise the cold burden groove, cylindrical shell, blowpit, cold burden groove are horizontally placed on the end below of cylindrical shell, and blowpit is horizontally placed on the other end below of cylindrical shell, the footpath of cylindrical shell upwards is provided with the twice rolling ring at least, in the other end of the described cylindrical shell of being located at blowpit, be provided with far infrared and adorn, described far infrared generating means covers the bocca of flame generating means.
Described reverse-flow far infrared and flame dual heating type drying barrel, wherein said far infrared generating means also is provided with temperature sensor.
Described reverse-flow far infrared and flame dual heating type drying barrel, wherein said cold burden groove links to each other with cleaner.
Beneficial effect of the present invention: because the far infrared generating means has covered the overwhelming majority's of flame generating means flame, avoided pitch directly to contact the high temperature that flame produces, so effectively avoided the aging of pitch, just can not produce toxic gas yet, and be that the power source of far infrared generating means produces the infrared ray that needs and also reduced scattering and disappearing of heat with flame, reached higher heat energy utilization rate.

Five, the specific embodiment
Below just the present invention is further illustrated in conjunction with the accompanying drawings.
The present invention includes cold burden groove 1, cylindrical shell 2, blowpit 4, cold burden groove 1 are horizontally placed on the end below of cylindrical shell 2, and blowpit 4 is horizontally placed on the other end below of cylindrical shell 2, the footpath of cylindrical shell 2 upwards is provided with twice rolling ring 3 at least, in the other end of the cylindrical shell 2 that is provided with blowpit 4, be provided with far infrared generating means 5, outside the other end of the described cylindrical shell 2 that is provided with blowpit 4, be provided with flame generating means 6, described far infrared generating means 5 covers the bocca 61 of flame generating means.
Described reverse-flow far infrared and flame dual heating type drying barrel, wherein said far infrared generating means 5 also is provided with temperature sensor.
Described reverse-flow far infrared and flame dual heating type drying barrel, wherein said cold burden groove links to each other with cleaner.
The compound that cold burden groove 1 is come at first by the hot blast zone, when cylindrical shell 2 advances, also constantly rolls in tube, and hot blast is more efficiently like this heats old asphalt mixture; Old asphalt mixture through the hot blast heating arrives far infrared generating means district then, far infrared generating means 5 sends far infrared old asphalt mixture is further heated, in heating process owing on the Far-infrared Heating device, be provided with temperature sensor, link to each other with monitoring system by temperature sensor and just can well control the temperature of heating, avoid temperature too high and produce toxic gas.Just start flame generating means 6 when compound adds, the flame that flame generating means 6 produces brings the power source of high temperature as far infrared generating means 5, produces far infrared.Can cover most of flame of the bocca 61 of flame generating means 6 in the whole process owing to far infrared generating means 5, effectively completely cut off contacting of flame and old asphalt mixture, so can not produce the ageing of asphalt phenomenon, just do not have toxic gas yet and generate, and reduced scattering and disappearing of heat.At last, the old asphalt mixture that heats is discharged by blowpit 4.In addition, an end of cold burden groove 1 can also be connected with cleaner to reduce the dust that produces in production process injury and the environment damage to operating personnel.
Here description of the invention and application is illustrative, is not to want with scope restriction of the present invention in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the actual replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present invention or substantive characteristics, and the present invention can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.Under the situation that does not break away from the scope of the invention and spirit, can carry out other distortion and change here to disclosed embodiment.
