Description

Technical Field

[0001] The utility model belongs to the field of asphalt concrete production, in particular to asphalt heat regeneration equipment with a heat regeneration main building. Background Art

[0002] With the rapid development of asphalt pavement construction in my country and the reconstruction and renovation of a large number of high-grade roads, the recycling and reuse of asphalt concrete recycled materials has been highly valued and widely concerned. In order to be able to add a higher proportion of old asphalt materials, a new generation of countercurrent asphalt concrete plant hot regeneration equipment has come into being. The countercurrent asphalt concrete plant hot regeneration equipment uses convection flue gas in the opposite direction of the material flow to heat the asphalt concrete recycled materials, and controls the flue gas temperature of the heat exchange, so as to achieve gentle heating of the asphalt concrete recycled materials and prevent the asphalt concrete recycled materials from aging during the heating process. For example, the countercurrent asphalt mixture plant hot regeneration equipment disclosed in patent number ZL201721526225.6 includes a recycled material supply equipment and a raw material mixing building. The recycled material supply equipment includes a drying drum arranged obliquely and provided with an input end and an output end, and a burner for supplying heat to the drying drum. The burner supplies heat to the output end of the drying drum through a flue gas duct. The existing countercurrent asphalt concrete plant hot regeneration equipment mixes the burner flue gas and the drum exhaust gas through the furnace to obtain mild hot flue gas, which then enters the regeneration drying drum for convective heat exchange on the asphalt concrete recycled material. The traditional furnace layout is parallel to the regeneration drying drum, which occupies a large area and the regeneration hot material buffer bin is bonded. Utility Model Content

[0013] Figure 1 It is a structural schematic diagram of an asphalt hot regeneration equipment with a hot regeneration main building. DETAILED DESCRIPTION

[0014] The present invention is further described below through specific implementation methods.

[0015] An asphalt hot regeneration equipment with a hot regeneration main building, comprising an asphalt hot regeneration mixing system 1, a combustion system 2, a hot regeneration main building 3, and a regeneration hot material buffer 4;

[0016] The asphalt hot regeneration mixing system 1 includes a regeneration drying drum 11, a discharge end seat 12, a feed end seat 13, and an elevator 14. The two ends of the regeneration drying drum 11 are a discharge end 111 and a feed end 112, respectively. The side of the discharge end seat 12 is connected to the discharge end 111 of the regeneration drying drum 11, the upper end surface is connected to the combustion system 2, and the lower end surface is connected to the regeneration material buffer bin 4. The side of the feed end seat 13 is connected to the feed end 112 of the regeneration drying drum 11. The elevator 14 is arranged on one side of the feed end 112 of the regeneration drying drum 11, and the upper end surface of the feed end seat 13 is connected to the elevator 14.

[0017] The combustion system 2 includes a burner 21 and a furnace 22. The burner 21 is arranged above the furnace 22. The furnace 22 is arranged vertically. The bottom of the furnace 22 is connected to the upper end surface of the discharge end 12. The hot flue gas generated by the burner 21 is mixed with the tail gas, and then passes through the furnace 22 and the discharge end seat 12 in sequence, and finally enters the regeneration drying drum 11 to perform convection heat exchange with the asphalt concrete recycled material to heat the asphalt concrete recycled material.

[0018] The regeneration hot material buffer bin 4 is connected to the lower end surface of the discharge end seat 12, and the hot asphalt concrete recycled material heated by the regeneration drying drum 11 is discharged to the regeneration hot material buffer bin 4 through the discharge end seat 12. At the same time, the hot flue gas in the discharge end seat 12 will enter the regeneration hot material buffer bin 4 together, and the regeneration hot material buffer bin 4 will have a thermal radiation heating and heat preservation effect;

[0019] The heat regeneration main building 3 is arranged on one side of the discharge end 111 of the regeneration drying drum 11, and the burner 21, the furnace 22, the discharge end seat 12, and the regeneration hot material buffer bin 4 are arranged on the heat regeneration main building 3 from top to bottom.

[0020] Reference Figure 1 As shown, the working process of the asphalt hot regeneration equipment with a hot regeneration main building provided by the utility model is as follows:

[0021] The hoist 14 lifts the asphalt concrete recycled material to a high place, and enters the regeneration drying drum 11 from the feed end seat 13 through its internal chute;

[0022] The regeneration drying drum 11 rotates, and the hot flue gas generated by the burner 21 is mixed with the exhaust gas, and then discharged from the bottom of the vertically arranged furnace 22 through the negative pressure of the induced draft fan, passes through the discharge end seat 12, and finally enters the regeneration drying drum 11 to perform convection heat exchange with the asphalt concrete recycled material, thereby heating the asphalt concrete recycled material;

[0023] The heated asphalt concrete recycled material is discharged into the regenerative hot material buffer bin 4 through the discharge end seat 12. At the same time, the hot flue gas in the discharge end seat 12 will also enter the regenerative hot material buffer bin 4. The hot flue gas has a thermal radiation heating and heat preservation effect on the material end seat 12 and the regenerative hot material buffer bin 4.

[0024] The above-mentioned asphalt hot regeneration equipment with a hot regeneration main building arranges the combustion system 2, the discharge end seat 12, and the regenerated hot material buffer bin 4 from top to bottom in sequence on the hot regeneration main building 3, saving equipment floor space. The hot flue gas in the discharge end seat 12 can heat and insulate the discharge end seat and the regenerated hot material buffer bin by thermal radiation, which is beneficial to prevent the regenerated material from sticking to the discharge end seat and the regenerated hot material buffer bin.

[0025] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
