[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention uses a cleaning mechanism. When separating the oil and stone from the waste asphalt mixture, the waste asphalt waste in the cleaning tank can be cleaned through the flushing component. At the same time, the water in the cleaning tank is disturbed, so that the water in the cleaning tank is in a flowing state, and the waste asphalt waste in the cleaning tank can be flushed. By using the disturbing component, the water in the cleaning tank can be aerated, and the air ejected from the aeration pipe can further impact the water in the cleaning tank, thereby improving the disturbing effect on the water and improving the flushing effect on the waste asphalt mixture.

[0022] 2. The present invention uses a capillary tube. When the air compressor is working, the compressed air generated passes through the aeration tube and is ejected from the capillary tube. While causing the water to flow, the reaction force generated by the capillary tube when the air is ejected can cause the aeration tube to rotate with the rotary joint as the axis, thereby causing the aeration tube to rotate and aerate in the cleaning tank, which can effectively increase the aeration range, allow the water flow to penetrate into the waste pile, clean the waste, and effectively improve the cleaning effect.

[0023] 3. The present invention uses a filtering mechanism to allow water to pass through the first cylinder, the second cylinder and the third cylinder. After the activated carbon, sepiolite, filter cotton and filter mesh are combined, the water entering the water tank can be filtered multiple times, which can absorb odors, heavy metals and impurities in the water, and can effectively improve the filtering quality of the water entering the water tank, so that the cleaning water can be reused.

[0024] 4. The present invention can disassemble the first cylinder, the second cylinder and the third cylinder by using the cylinder cover, so as to facilitate regular replacement or cleaning of the activated carbon, sepiolite, filter cotton and filter screen to ensure the filtering effect of the filtering mechanism.

[0025] 5. The present invention uses heat pipes. After the heated water in the cleaning pool flows into the water tank, the heat pipes transfer the heat in the water tank to the insulation shell. The temperature in the insulation shell is then transferred to the separation tank, which can increase the temperature of the separation tank. When heating the cleaned waste asphalt mixture, it can be heated quickly compared to the unheated separation tank, thereby improving the separation efficiency.

[0026] 6. The present invention can increase the contact area between the separation tank and the hot air in the insulation shell by using the heat conducting sheet, so that the separation tank can be heated up quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0037] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 8 As shown, an embodiment of the present invention provides a waste asphalt mixture oil-stone separation device, comprising a separation tank 1 and a cleaning mechanism 2. The separation tank 1 is used to separate the oil and stone from the waste asphalt mixture, and the separation tank 1 is connected to the cleaning mechanism 2.

[0039] The cleaning mechanism 2 includes a cleaning tank 3, a flushing component and a flow-disturbing component;

[0040] The flushing component is used to flush the waste;

[0041] The flow-disturbing component is used to keep the water flow in the cleaning pool 3 in a flowing state;

[0042] The flushing component and the flow-disturbing component are both connected to the cleaning pool 3;

[0043] The flow disturbance assembly includes an air compressor 4, a rotary joint 5 and an aeration pipe 6. The rotary joint 5 is fixedly installed in the cleaning tank 3. The aeration pipe 6 is connected to the rotating part of the rotary joint 5. The air compressor 4 is connected to the end of the rotary joint 5 away from the aeration pipe 6.

[0044] The flushing assembly includes a booster pump 7, a water pump 8 and a water outlet pipe 9. The booster pump 7 is connected to the water pump 8 through a liquid guide tube, and the water outlet pipe 9 is connected to the booster pump 7. The water inlet end of the water pump 8 is connected to a water tank 10, and the water outlet pipe 9 is connected to the cleaning pool 3.

[0045] It should be noted that a basket 20 is provided in the cleaning tank 3. The basket 20 is used to place waste asphalt mixture. The basket 20 is movably mounted in the cleaning tank 3 via a bracket 24. The aeration pipe 6 is located below the basket 20.

[0046] During cleaning, water can flow through the basket 20 to clean the waste asphalt mixture.

[0047] By adopting the above scheme, through the use of the cleaning mechanism 2, when the waste asphalt mixture is separated from the oil and stone, the waste asphalt waste in the cleaning tank 3 can be cleaned through the flushing component, and at the same time, the water in the cleaning tank is disturbed, so that the water in the cleaning tank 3 is in a flowing state, and the waste asphalt waste in the cleaning tank 3 can be flushed. By using the disturbing component, the water in the cleaning tank 3 can be aerated, and the air ejected from the aeration pipe 6 can further impact the water in the cleaning tank, thereby improving the disturbing effect on the water and improving the flushing effect on the waste asphalt mixture.

[0048] In this embodiment, the aeration tube 6 is provided with a plurality of groups of thin tubes 11 in an annular array, and the plurality of groups of thin tubes 11 are all arranged tangentially to the outer wall of the aeration tube 6 .

[0049] It should be noted that there are no less than three groups of capillaries 11 .

[0050] By adopting the above scheme, through the use of the capillary tube 11, when the air compressor 4 is working, the compressed air generated passes through the aeration pipe 6 and is ejected by the capillary tube 11. While causing the water to flow, the reaction force generated by the capillary tube 11 when ejecting the air can cause the aeration pipe 6 to rotate with the rotary joint 5 as the axis, thereby causing the aeration pipe 6 to rotate and aerate in the cleaning tank 3, which can effectively increase the aeration range, allow the water flow to penetrate into the waste pile, clean the waste, and effectively improve the cleaning effect.

[0051] In this embodiment, the bottom of the cleaning pool 3 is connected to the water tank 10 through a water inlet pipe 12 , and a Y-shaped filter 13 is installed on the water inlet pipe 12 . The Y-shaped filter 13 is used to filter the water flowing from the cleaning pool 3 into the water tank 10 .

[0052] By adopting the above solution, through the use of the Y-shaped filter 13, when the water in the cleaning pool 3 flows into the water tank 10, the cleaning wastewater passing through the water pipe 12 can be filtered, which can effectively reduce the impurities entering the water tank 10.

[0053] In this embodiment, a filtering mechanism is provided in the water tank 10, and the filtering mechanism includes a first cylinder 14, a second cylinder 15 and a third cylinder 16. The first cylinder 14 is used to place sepiolite and filter cotton, the second cylinder 15 is used to place activated carbon and filter cotton, and the third cylinder 16 is used to place filter cotton and filter mesh. The third cylinder 16 is connected to the water tank 10, the water inlet pipe 12 is connected to the first cylinder 14, and the second cylinder 15 is connected to the first cylinder 14 and the second cylinder 15 respectively.

[0054] By adopting the above scheme, through the use of the filtering mechanism, the water passes through the first cylinder 14, the second cylinder 15 and the third cylinder 16, and through the cooperation of activated carbon, sepiolite, filter cotton and filter mesh, the water entering the water tank 10 can be filtered multiple times, which can absorb odors, heavy metals and impurities in the water, and can effectively improve the filtration quality of the water entering the water tank, so that the cleaning water can be reused.

[0055] In this embodiment, a cylinder cover 17 is detachably mounted on the upper portion of the first cylinder 14 , and the first cylinder 14 , the second cylinder 15 and the third cylinder 16 are arranged in the same manner.

[0056] It should be noted that the cylinder cover 17 is mounted on the first cylinder 14 in a threaded manner;

[0057] The connecting pipes between the first cylinder 14, the second cylinder 15 and the third cylinder 16 are all configured as detachable connecting pipes;

[0058] The first cylinder 14 , the second cylinder 15 and the third cylinder 16 can be fixedly installed in the water tank in a detachable manner, including but not limited to bolt fixation or clamping fixation.

[0059] By adopting the above solution, the first cylinder 14, the second cylinder 15 and the third cylinder 16 can be disassembled through the use of the cylinder cover 17, so that the activated carbon, sepiolite, filter cotton and filter screen can be replaced or cleaned regularly to ensure the filtering effect of the filtering mechanism.

[0060] In this embodiment, a heater 18 is installed on the side of the cleaning pool 3 , and the heater 18 is used to heat the water in the cleaning pool 3 .

[0061] By adopting the above scheme, the water in the cleaning tank 3 can be heated by using the heater 18, which can improve the cleaning effect of the waste asphalt mixture, and can preheat the asphalt mixture, which can reduce the heating time of the asphalt mixture in the separation tank.

[0062] In this embodiment, the water outlet pipe 9 is arranged in a frame shape, and a plurality of water outlet holes 19 are provided on the water outlet pipe 9 .

[0063] It should be noted that the water outlet holes 19 are configured as upper inclined holes and lower inclined holes, and the angle between the water outlet holes 19 and the horizontal plane is set to 20-30 degrees, wherein the water outlet direction of the upper inclined hole is directly facing the basket 20.

[0064] By adopting the above scheme, by setting the water outlet 19 as an inclined hole, after the booster pump 7 sends water into the water outlet pipe 9, the water flowing out of the water outlet 19 irregularly disturbs the cleaning pool 3, causing the water flow to irregularly flush the waste asphalt mixture, and can penetrate into the gaps in the waste material pile for cleaning, and can flush the surface of the waste material, which can effectively improve the cleaning effect.

[0065] In this embodiment, the outer wall of the water tank 10 is set as an insulation box, and a heat pipe 21 is provided on the water tank 10. One end of the heat pipe 21 is connected to the water tank 10, and one end of the heat pipe 21 is connected to an insulation shell 22. The insulation shell 22 is fixedly installed on the outer wall of the separation tank 1.

[0066] With the above solution, through the use of the heat pipe 21, after the heated water in the cleaning tank 3 flows into the water tank 10, the heat pipe 21 transfers the heat in the water tank 10 to the insulation shell 22, and the temperature in the insulation shell 22 is then transferred to the separation tank 1, so that the separation tank 1 can be heated. When the cleaned waste asphalt mixture is heated, the temperature can be increased faster than that of an unheated separation tank, thereby improving the separation efficiency.

[0067] A plurality of heat conducting fins 23 are provided on the outer wall of the separation tank 1 . The heat conducting fins 23 are located inside the heat-insulating shell 22 . The heat conducting fins 23 are used to preheat the separation tank 1 .

[0068] It should be noted that: there are no less than ten heat conducting sheets 23;

[0069] One end of the heat pipe 21 is inserted into the water tank 10, and the other end of the heat pipe 21 is in contact with the inner layer of the insulation shell 22;

[0070] An insulation layer is provided on the outer wall of the heat conducting pipe, which can ensure that the heat conducting pipe 21 reduces heat loss during the heat conducting process.

[0071] The above solution uses the heat conducting sheet 23 to increase the contact area between the separation tank 1 and the hot gas in the heat-insulating shell 22, thereby increasing the heat conduction area of ​​the separation tank 1 and allowing the separation tank 1 to heat up quickly.

[0072] During use, by using the cleaning mechanism 2, when the waste asphalt mixture is subjected to oil-stone separation, the waste asphalt waste in the cleaning tank 3 can be cleaned by the flushing component, and at the same time, the water in the cleaning tank is disturbed, so that the water in the cleaning tank is in a flowing state, and the waste asphalt waste in the cleaning tank can be flushed. By using the disturbing component, the water in the cleaning tank 3 can be aerated, and the air ejected from the aeration pipe 6 can further impact the water in the cleaning tank, thereby improving the disturbing effect on the water and improving the flushing effect on the waste asphalt mixture.

[0073] By using the capillary tube 11, when the air compressor 4 is working, the compressed air generated passes through the aeration pipe 6 and is ejected from the capillary tube 11. While the water is flowing, the reaction force generated by the capillary tube 11 when the air is ejected can cause the aeration pipe 6 to rotate around the rotary joint 5 as the axis, thereby causing the aeration pipe 6 to rotate and aerate in the cleaning tank 3, which can effectively increase the aeration range, allow the water flow to penetrate into the waste pile, clean the waste, and effectively improve the cleaning effect.

[0074] By using the Y-shaped filter 13, when the water in the cleaning pool 3 flows into the water tank 10, the cleaning wastewater passing through the water diversion pipe 12 can be filtered, which can effectively reduce the impurities entering the water tank 10;

[0075] By using the filtering mechanism, water passes through the first cylinder 14, the second cylinder 15 and the third cylinder 16, and through the combination of activated carbon, sepiolite, filter cotton and filter mesh, the water entering the water tank 10 can be filtered multiple times, which can absorb odors, heavy metals and impurities in the water, and can effectively improve the filtering quality of the water entering the water tank, so that the cleaning water can be reused;

[0076] By using the cylinder cover 17, the first cylinder 14, the second cylinder 15 and the third cylinder 16 can be disassembled, which is convenient for regularly replacing or cleaning the activated carbon, sepiolite, filter cotton and filter screen to ensure the filtering effect of the filtering mechanism;

[0077] By using the heat pipe 21, after the heated water in the cleaning tank 3 flows into the water tank 10, the heat pipe 21 transfers the heat in the water tank 10 to the insulation shell 22. The temperature in the insulation shell 22 is then transferred to the separation tank 1, which can increase the temperature of the separation tank 1. When heating the cleaned waste asphalt mixture, the temperature can be increased faster than that of an unheated separation tank, thereby improving the separation efficiency.

[0078] By using the heat conducting sheet 23 , the contact area between the separation tank 1 and the hot air in the heat-insulating shell 22 can be increased, so that the separation tank 1 can be heated up quickly.
