Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt production technology, and in particular to a recycled asphalt mixture production equipment. Background Technology
[0002] Asphalt recycling is the reverse process of aging. It usually involves adding recycling agents, such as corn oil or lubricating oil. Adding recycling agents reduces the relative content of asphaltene, increases the solubility of soft asphaltene in asphaltene, improves the compatibility of asphalt, and increases the penetration and ductility of asphalt, thus restoring it to or near its original properties.
[0003] In the prior art, when mixing recycled asphalt, the old asphalt material and the recycling agent are introduced into the shell and stirred. However, the old asphalt material contains a lot of lumpy material. When the lumpy old asphalt is mixed with the recycling agent, it cannot fully contact the recycling agent, thereby reducing the mixing effect of the asphalt material and the recycling agent. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where blocky old asphalt cannot fully contact the recycler when mixed with it, thus reducing the mixing effect of asphalt materials and recyclers. Therefore, this invention proposes a recycled asphalt mixture production equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design a recycled asphalt mixture production equipment, including a support frame, a first housing fixedly connected to the support frame, a motor fixedly connected to the upper end of the first housing, a feeding mechanism connected to the upper end of the first housing, a guide pipe connected to one side of the first housing, a second housing connected to one end of the guide pipe, a feed hopper connected to the upper end of the second housing, a filter screen connected inside the second housing, a second agitator rotatably connected to the upper end of the second housing, one end of the second agitator extending into the second housing, the second agitator being connected to the output end of the motor via a belt drive, and a plurality of heating elements evenly spaced along the axis of the second housing.
[0007] Preferably, an anti-slip pad is fixedly connected to the bottom end of the support frame.
[0008] Preferably, the feeding mechanism includes a liquid injection pipe connected to the upper end of the first housing, the upper end of the liquid injection pipe being connected to a liquid storage tank, a solenoid valve being connected to the liquid injection pipe, and a flow meter being connected to the liquid injection pipe.
[0009] Preferably, the liquid storage tank is a transparent tank.
[0010] Preferably, the upper end of the first housing is connected to an exhaust pipe.
[0011] Preferably, the upper end of the exhaust pipe is connected to a flue gas treatment mechanism, the flue gas treatment mechanism includes an open box, the open box is connected to one end of the exhaust pipe, one side of the open box is connected to an exhaust pipe, and the inside of the open box has a plurality of grooved frames connected at equal intervals along the length direction on both sides, and each grooved frame is connected to an activated carbon filter.
[0012] The recycled asphalt mixture production equipment proposed in this utility model has the following advantages:
[0013] After the heating element is powered on, the old asphalt material is heated. At the same time, the motor is powered on and starts. After the motor starts, it drives the second agitator to rotate through the belt drive. The rotation of the second agitator stirs the old asphalt material on the filter screen. The heated old asphalt material softens, and the lumpy old asphalt material is dispersed under the stirring of the second agitator, thereby improving the mixing effect of the old asphalt material and the recycling agent.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1: Refer to Figure 1-3 A recycled asphalt mixture production equipment includes a support frame 1, with an anti-slip pad fixedly connected to the bottom end of the support frame 1. A first housing 2 is fixedly connected to the support frame 1, and a motor 3 is fixedly connected to the upper end of the first housing 2. A feeding mechanism 5 is connected to the upper end of the first housing 2. The output end of the motor 3 extends into the first housing 2 and is fixedly connected to a first mixing element 4. An exhaust pipe 6 is connected to the upper end of the first housing 2. A guide pipe 7 is connected to one side of the first housing 2. One end of the guide pipe 7 is connected to a second housing 8. A feed hopper 9 is connected to the upper end of the second housing 8. A filter screen 10 is connected inside the second housing 8. A second mixing element 11 is rotatably connected to the upper end of the second housing 8. One end of the second mixing element 11 extends into the second housing 8. The second mixing element 11 is connected to the output end of the motor 3 via a belt drive 12. Several heating elements 13 are evenly spaced along the axis of the second housing 8.
[0021] Work process:
[0022] The old asphalt material is fed into the second housing 8 through the feed hopper 9. The old asphalt material falls onto the filter screen 10. After the heating element 13 is powered on, it heats the old asphalt material. At the same time, the motor 3 is powered on and starts. After the motor 3 starts, it drives the second stirring element 11 to rotate through the belt drive element 12. After the second stirring element 11 rotates, it stirs the old asphalt material on the filter screen 10. The heated old asphalt material softens, and the blocky old asphalt material is dispersed under the stirring of the second stirring element 11.
[0023] The dispersed old asphalt material passes through the filter screen 10 and enters the feed pipe 7. The feed pipe 7 guides the old asphalt material into the first housing 2. The feeding mechanism 5 releases the recycling agent. The motor 3 drives the first stirring component 4 to rotate. After the first stirring component 4 rotates, it stirs and mixes the old asphalt material and the recycling agent. Since the blocky old asphalt material is filtered and dispersed by the filter screen 10, the mixing effect of the old asphalt material and the recycling agent is improved.
[0024] Example 2: In Example 1, when the regenerant is released by the feeding mechanism 5, it is inconvenient to control the amount of regenerant. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the feeding mechanism 5 includes a liquid injection pipe 51, which is connected to the upper end of the first housing 2. The upper end of the liquid injection pipe 51 is connected to a liquid storage tank 52, which is a transparent box. A solenoid valve 53 is connected to the liquid injection pipe 51, and a flow meter 54 is connected to the liquid injection pipe 51. When the regenerant is released, the solenoid valve 53 is opened, and the regenerant in the liquid storage tank 52 flows into the liquid injection pipe 51 under its own gravity. The liquid injection pipe 51 introduces the regenerant into the first housing 2. The flow meter 54 measures the released regenerant, which facilitates the control of the amount of regenerant released.
[0025] Example 3: In Example 1, when the old asphalt material and recycling agent are mixed after the first mixing component 4 rotates, the fumes from the asphalt are emitted from the exhaust pipe 6. Direct emission of these fumes would pollute the air. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the upper end of the exhaust pipe 6 is connected to a flue gas treatment mechanism 14. The flue gas treatment mechanism 14 includes an open box 141, which is connected to one end of the exhaust pipe 6. One side of the open box 141 is connected to an exhaust pipe 142. Several grooved frames 143 are evenly spaced along the length direction on both sides of the interior of the open box 141. Each grooved frame 143 is connected to an activated carbon filter 144. The flue gas in the first housing 2 is introduced into the open box 141 through the exhaust pipe 6. The flue gas gradually comes into contact with different activated carbon filters 144. The activated carbon filters 144 adsorb the organic matter in the flue gas. The treated flue gas is released from the exhaust pipe 142, reducing air pollution.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
