Abstract
The utility model relates to an asphalt mixing technology, and discloses an exhaust gas recycling device of an asphalt mixture. The exhaust gas recycling device of the asphalt mixture comprises a preheat rotating cylinder, wherein an independently fixed exhaust gas heat collection pipe penetrates through the axial center of the preheat rotating cylinder; the two ends of the preheat rotating cylinder are provided with a feed port and a discharge port respectively; the inner wall of the preheat rotating cylinder is provided with a plurality of feed inner teeth which radially extend out in the radial direction; the feed inner teeth are spirally distributed on the inner wall of the preheat rotating cylinder; and cold asphalt and cold aggregate are placed in the preheat rotating cylinder from the feed port, are gradually conveyed to the discharge port by the spiral inner teeth through the rotation of the preheat rotating cylinder and are gradually heated to realize preheating by the middle exhaust gas heat collection pipe during rotation so as to save energy.
Description
Technical field
The utility model relates to pitch mix technology, particularly a kind of waste gas re-use device of asphalt mixture.
Background technology
The mix of asphalt needs earlier the ratio between each material to be calculated, each material with the cold burden storehouse mixes in proportion again, transporting into after with the cold burden dedusting, cylinder carries out dry dedusting, carry out heat treated after finishing, heated bitumen and heat gathered materials to mix carry out mix, add breeze, after mix is finished, compound is excreted to the scene that is transported on the dumper.Can produce a large amount of high-temp waste gas when heated bitumen and hot aggregate blending, carry a large amount of heats, if can not utilize again these high-temp waste gas, will cause huge thermal waste.
Summary of the invention
The purpose of this utility model is to provide a kind of waste gas re-use device of asphalt mixture, and the high-temp waste gas that produces during with heated bitumen and hot aggregate blending preheats cold pitch and cold gathering materials, and energy savings is beneficial to environmental protection.
The utility model is achieved by the following technical solutions.
A kind of waste gas re-use device of asphalt mixture, it is characterized in that, comprise the preheating rotating cylinder, the axial centre of described preheating rotating cylinder is penetrated with the waste gas thermal-collecting tube of independent stationary, the two ends of described preheating rotating cylinder are respectively feeding mouth and discharging opening, the inwall of described preheating rotating cylinder is provided with a plurality of radially-protruding feeding internal tooths, and described a plurality of feeding internal tooths distribute with helix at the inwall of preheating rotating cylinder.
Characteristics of the present utility model and further the improvement are:
Described waste gas thermal-collecting tube is metal tube.
The outer wall of described waste gas thermal-collecting tube is provided with radiation tooth.
Described feeding internal tooth is the L type.
The waste gas re-use device of asphalt mixture of the present utility model, from feeding mouth cold pitch and cold gathering materials are put into the preheating rotating cylinder, rotate through the preheating rotating cylinder, feeding internal tooth by screw type is transported to discharging opening gradually with cold pitch and cold gathering materials, cold pitch and cold gathering materials in rotary course, because the heating that is subjected to middle waste gas thermal-collecting tube heats up gradually, obtain preheating, thereby save the energy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the side-looking structural representation of the waste gas re-use device of asphalt mixture of the present utility model.
Fig. 2 is the sectional structure schematic diagram of the waste gas re-use device of the asphalt mixture shown in Fig. 1.
Fig. 3 is the perspective structure schematic diagram of the waste gas re-use device of the asphalt mixture shown in Fig. 1.
Among the figure: 1, preheating rotating cylinder; 2, waste gas thermal-collecting tube; 3, feeding internal tooth; 4, radiation tooth, 5, feeding mouth; 6, discharging opening.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, be respectively the waste gas re-use device of asphalt mixture of the present utility model side-looking, analyse and observe, the perspective structure schematic diagram.Wherein, the axial centre of preheating rotating cylinder 1 is penetrated with the waste gas thermal-collecting tube 2 of independent stationary, waste gas thermal-collecting tube 2 transfixions, and preheating rotating cylinder 1 is around 2 rotations of waste gas thermal-collecting tube; Waste gas thermal-collecting tube 2 is provided with radiation tooth 4 for metal tube and its outer wall, heat in it can be passed to efficiently cold pitch and cold gathering materials in the preheating rotating cylinder 1, the two ends of preheating rotating cylinder 1 are respectively feeding mouth 5 and discharging opening 6, the inwall of preheating rotating cylinder 1 is provided with a plurality of radially-protruding feeding internal tooths 3, feeding internal tooth 3 is the L type, and a plurality of feeding internal tooths 3 distribute with helix at the inwall of preheating rotating cylinder 1.
The waste gas re-use device of asphalt mixture of the present utility model, a large amount of high-temp waste gas that one end of waste gas thermal-collecting tube 2 produces when collecting heated bitumen and hot aggregate blending, in addition, by feeding mouth 5 cold pitch and cold gathering materials are placed in the preheating rotating cylinder 1,1 rotation of preheating rotating cylinder, by the feeding internal tooth that the line in the shape of a spiral in it distributes, cold pitch and cold gathering materials are sent from discharging opening 6 after the heating gradually, finish preheating.The waste gas re-use device of asphalt mixture of the present utility model, the high-temp waste gas that produces during with heated bitumen and hot aggregate blending preheats cold pitch and cold gathering materials, and is simple in structure, good reliability, energy savings is beneficial to environmental protection.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
