Description

Technical Field

[0001] This utility model relates to the field of pretreatment technology for waste asphalt pavement materials, and more specifically, it relates to a pretreatment device based on the recycling and reuse of waste asphalt pavement materials. Background Technology

[0002] Waste asphalt pavement materials refer to asphalt-related materials salvaged from the renovation and dismantling of used asphalt roads. Although they are waste materials, the asphalt and aggregates within them still have certain economic value. Through appropriate processing technologies, waste asphalt pavement materials can be recycled and reused to produce recycled asphalt mixtures for road construction and other projects. This not only saves resources but also reduces project costs.

[0003] Due to factors such as water seepage and inadequate drainage facilities, the water content in asphalt pavement materials may increase. This increased water content negatively impacts their reuse. During the crushing and recycling of asphalt pavement materials, blocky asphalt waste is formed, which contains moisture. Therefore, it is necessary to remove this moisture. Existing pretreatment devices for recycling waste asphalt pavement materials place the blocky waste material (which needs moisture removal) statically (without stirring) in a filter for filtration, thus separating the water from the blocky waste material. However, because some blocky waste material has pits on its surface, water tends to accumulate inside these pits. Furthermore, existing pretreatment devices for recycling waste asphalt pavement materials cannot allow the blocky waste material to roll during dehydration, preventing the water from draining from these pits and affecting dehydration efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pretreatment device based on the recycling and reuse of waste asphalt pavement materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A loading bin, the interior of which is used to hold and load waste asphalt pavement material to be processed, is fixedly connected to the upper surface of the workbench.

[0008] The discharge pipe is connected to the interior of the loading box, through which the waste asphalt pavement material to be processed inside the loading box is discharged.

[0009] The processing box is fixedly connected to the workbench. The processing box has an inlet and an outlet on its two sides, and the inlet is matched with the outlet pipe.

[0010] An annular plate is rotatably and sealed inside the processing box. An inclined baffle is fixedly connected to the outer wall of the annular plate. The baffle is movably and sealed to the inner wall of the processing box. A loading zone is formed between the annular plate, the processing box, and the two baffles. Waste asphalt pavement material inside the discharge pipe enters the loading zone through the inlet.

[0011] The baffle has an inlet on its surface and a channel inside it. The inlet is connected to the channel. The annular plate has a drain. The water content of the waste asphalt pavement material inside the loading area is discharged through the inlet, the channel and the drain.

An inlet is provided on the surface of each baffle, allowing the blocky asphalt waste material requiring dehydration to be located inside the loading section. The annular plate rotates inside the processing box, causing the blocky asphalt waste material to move within the loading section. Once inside, the material tumbles, facilitating the release of moisture through the inlet into the channels within the baffles. The moisture is then discharged through the outlet on the annular plate. Simultaneously, the rolling motion within the loading section alters the material's state, allowing water to drain from the pits on its surface, thus dehydrating the material and preventing water accumulation in these pits, facilitating the utilization of the waste asphalt pavement material.

[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] Reference Figures 1 to 9 As shown.

[0041] Example 1 further illustrates the pretreatment device based on the recycling and reuse of waste asphalt pavement materials proposed in this utility model.

[0042] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials includes a base plate 1, a workbench 3 fixedly connected above the base plate 1 via a support plate 2, and further includes:

[0043] The loading box 4 is used to hold the waste asphalt pavement material to be processed. The loading box 4 is fixedly connected to the upper surface of the workbench 3.

[0044] The discharge pipe 5 is connected to the interior of the loading box 4, and the waste asphalt pavement material to be processed inside the loading box 4 is discharged through the discharge pipe 5.

[0045] The processing box 6 is fixedly connected to the workbench 3. The processing box 6 has an inlet 7 and an outlet 8 on its two sides, and the inlet 7 is matched with the outlet pipe 5.

[0046] The annular plate 9 is rotatably and sealed inside the processing box 6. An inclined baffle 35 is fixedly connected to the outer wall of the annular plate 9. The baffle 35 is movably and sealed to the inner wall of the processing box 6. The annular plate 9, the processing box 6 and the two baffles 35 form a loading zone 10. The waste asphalt pavement material inside the discharge pipe 5 enters the loading zone 10 through the inlet 7.

[0047] The baffle 35 has an inlet 11 on its surface and a channel 12 inside it. The inlet 11 is connected to the channel 12. The annular plate 9 has a drain 13. The water content of the waste asphalt pavement material inside the loading section 10 is discharged through the inlet 11, the channel 12 and the drain 13.

[0048] This invention can effectively remove excess moisture from block asphalt waste materials, reduce the difficulty of subsequent processing, and thus improve the overall efficiency of recycling and reusing block asphalt waste materials.

[0049] The recycled, unprocessed blocky asphalt waste is placed inside the loading box 4. Since the inlet 7 matches the outlet pipe 5, the blocky asphalt waste inside the loading box 4 enters the loading section 10 through the outlet pipe 5 and inlet 7. The blocky asphalt waste is located on the upper surface of the baffle 35, causing the annular plate 9 to rotate inside the processing box 6. During the rotation of the annular plate 9, the baffle 35 rotates. Because the baffle 35 is sealed within the processing box 6, the blocky asphalt waste moves within the loading section 10 during the rotation of the baffle 35. When the blocky asphalt waste enters the loading section 10, due to the moisture content in the blocky asphalt waste, during the operation of the device, it moves with the movement of the annular plate 9... With the rotation of the baffle 35 (the rotation power can be provided by an external motor or other equipment), the blocky asphalt waste material is turned over in the loading section 10. Due to gravity or pushing, the water contained in the blocky asphalt waste material inside the loading section 10 can easily enter the channel 12 inside the baffle 35 through the liquid inlet 11, and finally be discharged out of the device through the liquid outlet 13 on the annular plate 9. At the same time, since the annular plate 9 and the baffle 35 rotate in the circumferential direction, it is easy to adjust the state of the blocky asphalt waste material inside the loading section 10. That is, the blocky asphalt waste material will roll inside the loading section 10, which facilitates the drainage of water accumulated in the pits of the blocky asphalt waste material, thus preventing water accumulation in the pits on the upper surface of the blocky asphalt waste material.

[0050] Example 2 adds the following technical features based on Example 1:

[0051] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials, wherein a discharge plate 14 is fixedly connected to the bottom of the inner side of the loading box 4, and the small end of the discharge plate 14 is set towards the discharge pipe 5.

[0052] Since the upper surface of the discharge plate 14 is inclined and the upper surface of the discharge plate 14 is inclined downward toward the discharge pipe 5, it is convenient for the waste asphalt pavement material loaded inside the loading box 4 to be discharged into the discharge pipe 5.

[0053] A one-way valve 33 is installed inside the drain port 13. Due to the function of the one-way valve 33, water inside the channel 12 flows into the drain port 13, but water inside the drain port 13 cannot flow into the channel 12, thereby preventing water from other loading sections 10 from flowing into this loading section 10.

[0054] Example 3 adds the following technical features based on Example 2:

[0055] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials further includes:

[0056] Fixed plate 15 is fixedly connected to the top of workbench 3.

[0057] The drive device 16 has its fixed end fixedly connected to the side wall of the workbench 3. The drive shaft of the drive device 16 passes through the side wall of the processing box 6 and is fixedly connected to a connecting rod 17. The connecting rod 17 is fixedly connected to the annular plate 9.

[0058] The drive unit 16 is a drive motor.

[0059] The processing box 6 has a circular hole. The drive shaft of the drive motor passes through the circular hole and is fixedly connected to the connecting rod 17. The drive shaft of the drive motor rotates relative to the circular hole. The operation of the drive motor causes the connecting rod 17 to drive the annular plate 9 to rotate. During the rotation of the annular plate 9, the baffle 35 rotates. Therefore, during the rotation of the baffle 35, the blocky asphalt waste material inside the loading section 10 moves, thereby realizing the tumbling of the blocky asphalt waste material in the loading section 10. Due to the gravity or pushing action, the water contained in the blocky asphalt waste material inside the loading section 10 can easily enter the channel 12 inside the baffle 35 through the liquid inlet 11.

[0060] Example 4 adds the following technical features based on Example 3:

[0061] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials also includes a connecting plate 34, which is fixedly connected to the inside of the treatment box 6. A first inlet 18 is provided on the upper surface of the connecting plate 34, and a liquid flow channel 19 is provided inside the connecting plate 34, which is connected to the first inlet 18.

[0062] The processing box 6 has a second inlet 20 on its side wall, which is connected to the flow channel 19. The workbench 3 has a receiving cavity 21 inside, which is connected to the second inlet 20 and has a drain pipe 22 connected to it.

[0063] Water flows through the drain port 13 to the upper surface of the connecting plate 34, and then the water on the upper surface of the connecting plate 34 is discharged to the outside of the treatment box 6 through the first inlet 18, the flow channel 19, the second inlet 20, the receiving cavity 21 and the drain pipe 22.

[0064] Example 5 adds the following technical features based on Example 4:

[0065] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials also includes a liquid tank 23 fixedly connected to the base plate 1, and the liquid tank 23 is connected to the drain pipe 22.

[0066] The liquid tank 23 is connected to a discharge pipe 24, and a control valve 25 is installed on the discharge pipe 24.

[0067] The water on the upper surface of the connecting plate 34 flows sequentially through the first inlet 18, the flow channel 19, the second inlet 20, the receiving cavity 21, and the drain pipe 22 into the interior of the liquid tank 23. The water is collected and processed by the liquid tank 23. When it is necessary to drain the water collected inside the liquid tank 23, the operator opens the control valve 25, thereby realizing the drainage of the water collected inside the liquid tank 23 through the drain pipe 24.

[0068] Example 6 adds the following technical features based on Example 5:

[0069] A pretreatment device based on the recycling and reuse of waste asphalt pavement materials has a collection box 26 rotatably connected above the base plate 1, and the opening at the top of the collection box 26 corresponds to the discharge port 8.

[0070] A fixing block 27 is symmetrically fixedly connected to the base plate 1. A rotating rod 28 is rotatably connected between the fixing block 27 and the collection box 26. A pad 29 is fixedly connected to the upper surface of the base plate 1.

[0071] A first electric telescopic rod 30 is connected to the workbench 3, and the moving end of the first electric telescopic rod 30 is connected to the collection box 26.

[0072] The dehydrated blocky asphalt waste material inside the loading section 10 enters the collection box 26 through the discharge port 8. The rear end of the collection box 26 is supported by the pad plate 29. There is no connection between the pad plate 29 and the collection box 26. When it is necessary to discharge the blocky asphalt waste material collected inside the collection box 26, the first electric telescopic rod 30 works to push the collection box 26, causing the collection box 26 to rotate around the rotating rod 28. When the collection box 26 rotates to a horizontal state, that is, when the upper end of the collection box 26 is in a horizontal state, the blocky asphalt waste material collected inside the collection box 26 is poured out.

[0073] A second electric telescopic rod 31 is fixedly connected to the workbench 3. A moving plate 32 is fixedly connected to the moving end of the second electric telescopic rod 31. A baffle plate 36 is fixedly connected to the moving plate 32. The two baffle plates 36 correspond to the feed inlet 7 and the discharge outlet 8, respectively.

[0074] The inner side wall of the treatment box 6 is provided with a flow inlet hole 37, and the side wall of the treatment box 6 is provided with a liquid inlet channel 38. The liquid inlet channel 38 is connected to the flow inlet hole 37 and the liquid inlet channel 38 is connected to the interior of the liquid tank 23.

[0075] When it is necessary to dehydrate the blocky asphalt waste material inside the loading section 10, the second electric telescopic rod 31 works to move the moving plate 32. During the movement of the moving plate 32, the baffle plate 36 moves. Since the side wall of the processing box 6 has a through hole, the two baffle plates 36 pass through the through hole and are located inside the inlet 7 and outlet 8 respectively. That is, the two baffle plates 36 seal the inlet 7 and outlet 8 respectively. During the rotation of the annular plate 9, the baffle 35 rotates. Therefore, during the rotation of the baffle 35, the blocky asphalt waste material inside the loading section 10 moves. That is, some of the water in the blocky asphalt waste material enters the liquid inlet channel 38 through the inlet hole 37 due to the centrifugal force. Since the liquid inlet channel 38 is connected to the liquid tank 23 through a pipe (the pipe is not shown in the figure due to the blocking effect of the workbench 3 and other components), the water inside the liquid inlet channel 38 flows to the liquid tank 23, and the water is collected through the liquid tank 23.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
