Description

Technical Field

[0001] This invention relates to the field of asphalt processing, and in particular to an apparatus and process for preparing coated asphalt from oil sands asphalt. Background Technology

[0002] With the development of industrial technology, modern asphalt processing technology has become increasingly sophisticated. The raw materials for asphalt production are oil sands, crude oil, etc. When making asphalt from oil sands, the oil sands need to be heated first. The asphalt components in the oil sands need to reach a temperature of over 100 degrees Celsius to flow. Furthermore, asphalt has a lower density than mud and sand, which causes the mud and sand to settle at the bottom of the liquid asphalt before it is separated and extracted.

[0003] As disclosed in patent number 201921207459.3, the production device for coating asphalt includes a reactor and a support. The support is equipped with a hoist. The reactor includes a reactor cover and a reactor body. The reactor cover is detachably connected to the reactor body. The reactor cover is equipped with an air inlet pipe, an exhaust pipe, a pressure gauge, a sampling port, and a thermocouple insertion tube. The air inlet pipe extends to the lower part of the reactor body and is equipped with multiple air blowing holes. The thermocouple insertion tube extends to the middle and lower part of the reactor body. The reactor body is equipped with a stirring rod, which is driven by a stirring motor on the top of the reactor cover. An electric heating device is provided on the outside of the reactor body, and an insulation layer is provided on the outside of the electric heating device.

[0004] The device has the following drawbacks: First, its heating method is complex, making maintenance difficult. Second, the asphalt extraction method involves direct flow, making the asphalt difficult to store and transport. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an apparatus and process for preparing coated asphalt from oil sands. The oil sand material is fed into the processing chamber, and then hot vegetable oil is connected to the connecting pipe. The heat from the vegetable oil is transferred to the heating column, which in turn transfers heat to the oil sand material. As a result, the temperature of the oil sand reaches 200 degrees Celsius, causing the asphalt material in the oil sand to liquefy. Simultaneously, the sand and soil do not melt. Since the density of the sand and soil is greater than that of the asphalt, they settle at the bottom of the processing chamber, achieving asphalt separation. This heating method has high safety, and the oil-based heating method does not fluctuate significantly, resulting in high heating stability.

[0006] To solve the above problems, the present invention provides the following technical solution: an apparatus for preparing coated asphalt from oil sands asphalt, comprising a processing box, wherein the bottom of the processing box is provided with four grounding feet, and the bottom of the grounding feet is fixedly connected to a concrete ground through grounding plates; the top of the processing box is provided with an arch bridge, and a counter-stirring mechanism is provided below the arch bridge; the bottom of the processing box is provided with a detachable sealing plate, and a heating mechanism is provided on the sealing plate; a discharge pump is provided on the side wall of the processing box, and a slurry pipe is provided at the output end of the discharge pump; a discharge platform is provided on one side of the discharge pump, and two discharge plates are provided on the discharge platform. A vertical guide rail is provided, on which a lifting slider is slidably mounted. A cooling box is mounted on the side wall of the lifting slider, and a docking chamber is provided in the middle of the cooling box. An end plate is provided at the top of the unloading platform, and two electric push rods are provided at the top of the end plate. The output rods of the electric push rods pass through the end plate and connect to the top surface of the cooling box. A high-speed cooling mechanism is provided below the cooling box. The heating mechanism includes ten heating columns at the top of the sealing plate. Heating channels are provided on the inner side of the heating columns, and the heating channels are connected in series by a series pipe. A connecting pipe is led out between two connected heating channels and connected to hot liquid.

[0007] Furthermore, the hydrothermal fluid is vegetable oil, the input temperature of the vegetable oil is 200 degrees Celsius, and the heating column and series pipe are made of high-speed steel.

[0008] Furthermore, the heating column is composed of a semi-cylindrical structure, with the two halves locked together by countersunk bolts, and when the heating columns are combined, the heating channels also form a sealed channel with each other.

[0009] Furthermore, the opposing stirring mechanism includes an arch bridge fixed to the top of the processing box, a flat bearing seat at the bottom of the arch bridge, a turbine rotatably mounted at the bottom of the flat bearing seat, a number of annularly arranged diverging bars at the bottom of the turbine, the diverging bars passing through the inner side of the heating column, and a reverse stirring mechanism on the outer side of the turbine.

[0010] Furthermore, the reverse stirring mechanism includes a reverse ring, and a retaining ring matching the reverse ring is provided on the inner side of the processing box. The reverse ring is pressed onto the retaining ring by its own gravity. Stirring strips are arranged in a ring on the inner side wall of the reverse ring. The stirring strips are interspersed between the heating column and the radiating strips. The reverse ring is connected to the turbine through a linkage assembly.

[0011] Furthermore, the linkage component includes a stirring motor fixed to the side wall of the arch bridge. A worm gear is installed at the output end of the stirring motor. The worm gear and the turbine mesh with each other. A vertical bevel gear is also provided at the end of the worm gear. A mounting plate is provided at the top of the processing box. A horizontal bevel gear is rotatably provided at the bottom end of the mounting plate. The horizontal bevel gear and the vertical bevel gear mesh with each other. A rubber column is provided at the bottom end of the horizontal bevel gear. The rubber column is attached to the side wall of the friction ring.

[0012] Furthermore, rubber pads are provided on the sidewalls of both the rubber column and the friction ring, and the pressure between the rubber pads is maintained between thirty and fifty Newtons.

[0013] Furthermore, the high-speed cooling mechanism includes a cold air pump, the output end of which is equipped with a dispersion channel. The port of the dispersion channel is aligned with the bottom of the two cooling boxes. The cold air pump is connected to cold air, which is dry ice vaporization gas.

[0014] Furthermore, a cooling groove is provided at the bottom of the cooling box. The cooling groove is made of aluminum, and the distance between the cooling groove and the internal chamber of the cooling box is two millimeters.

[0015] Furthermore, the following steps are included:

[0016] S1. The oil sand material is fed into the processing box, and then hot vegetable oil is connected to the connecting pipe. The heat of the vegetable oil is transferred to the heating column, and the heating column transfers the heat to the oil sand material. As a result, the temperature of the oil sand will reach 200 degrees Celsius, and the asphalt material in the oil sand will liquefy. At the same time, the sand and soil will not melt. Since the density of the sand and soil is greater than that of the asphalt, they will settle at the bottom of the processing box, thus achieving the function of asphalt separation, which makes it easier to extract the asphalt material later.

[0017] S2. While the oil sand material is being heated, the stirring motor drives the worm and turbine to rotate together. The diverging bar at the bottom of the turbine stirs the oil sand material in the forward direction. The vertical bevel gear at the end of the worm drives the horizontal bevel gear and rubber column to rotate. The rubber column is attached to the friction ring and drives the reverse ring to rotate. The stirring bar at the bottom of the reverse ring drives the oil sand to stir in the reverse direction, which can increase the heat conduction efficiency of the stirred oil sand.

[0018] S3. The discharge pump extracts the asphalt layer from the melted oil sand. The discharge pump pushes the slurry asphalt into the cooling box through the slurry pipe. At this time, the cold air pump draws cold air and pushes it into the cooling tank. The asphalt inside the cooling box will cool down and solidify quickly. The electric push rod drives the two cooling boxes to move up and down in turn. When the cooling boxes move, the solid asphalt will detach from the inner wall of the cooling box, and then the whole piece of asphalt will be lifted up.

[0019] The beneficial effects of this invention are:

[0020] Firstly, the oil sand material is fed into the processing box, and then hot vegetable oil is connected to the connecting pipe. The heat of the vegetable oil is transferred to the heating column, which in turn transfers the heat to the oil sand material. As a result, the temperature of the oil sand reaches 200 degrees Celsius, and the asphalt material in the oil sand liquefies. At the same time, the sand and soil do not melt. Since the density of the sand and soil is greater than that of the asphalt, they will settle at the bottom of the processing box, thus achieving the separation of asphalt. This heating method is relatively safe, and the oil heating method does not fluctuate, resulting in high heating stability.

[0021] Secondly, while the oil sand material is being heated, the stirring motor drives the worm and turbine to rotate together. The diverging bar at the bottom of the turbine stirs the oil sand material in the forward direction. The vertical bevel gear at the end of the worm drives the horizontal bevel gear and rubber column to rotate. The rubber column adheres to the friction ring and drives the reverse ring to rotate. The stirring bar at the bottom of the reverse ring drives the oil sand to stir in the reverse direction, which can increase the heat conduction efficiency of the stirred oil sand.

[0022] Third, the discharge pump extracts the asphalt layer from the melted oil sand and pushes the slurry asphalt into the cooling box through the slurry pipe. At this time, the cold air pump draws cold air and pushes it into the cooling tank. The asphalt inside the cooling box will cool down and solidify quickly. The electric push rod drives the two cooling boxes to move up and down in turn. When the cooling boxes move, the solid asphalt will detach from the inner wall of the cooling box, and then the whole piece of asphalt will be lifted up. Attached Figure Description

[0036] Reference Figures 1 to 9The apparatus shown is for preparing coated asphalt from oil sands asphalt, including a processing box 1. The bottom of the processing box 1 is provided with four grounding feet 101, and the bottom ends of the grounding feet 101 are fixedly connected to a concrete surface via grounding plates. An arch bridge 102 is provided at the top of the processing box 1, and a counter-stirring mechanism is provided below the arch bridge 102. A detachable sealing plate 5 is provided at the bottom of the processing box 1, and a heating mechanism is provided on the sealing plate 5. A discharge port is provided on the side wall of the processing box 1. Pump 2, with a slurry pipe 201 at its output end, has a discharge platform 3 on one side. Two vertical guide rails 301 are mounted on the discharge platform 3, and a lifting slider 302 is slidably mounted on each guide rail 301. A cooling box 4 is hung on the side wall of the lifting slider 302, and a docking chamber is located in the middle of the cooling box 4. An end plate 303 is located at the top of the discharge platform 3, and two electric push rods 401 are mounted at the top of the end plate 303. The output rod of rod 401 passes through the end plate 303 and connects to the top surface of the cooling box 4. A high-speed cooling mechanism is provided below the cooling box 4. The heating mechanism includes ten heating columns 501 at the top of the sealing plate 5. Heating channels 504 are provided on the inner side of the heating columns 501, and the heating channels 504 are connected in series by a series pipe 502. A connecting pipe 503 is led out between two connected heating channels 504. The connecting pipe 503 is connected to hot liquid. The oil sand material is sent into the interior of the processing box 1, and then hot vegetable oil is connected to the connecting pipe 503. The heat of the vegetable oil is transferred to the heating column 501, and the heating column 501 transfers the heat to the oil sand material. As a result, the temperature of the oil sand will reach 200 degrees Celsius, and the asphalt material in the oil sand will liquefy. At the same time, the sand and soil will not melt. Since the density of the sand and soil is greater than that of the asphalt, they will settle at the bottom of the processing box 1, realizing the asphalt separation function, which facilitates the subsequent extraction of asphalt material. The heating method of vegetable oil also has a certain degree of safety.

[0037] like Figure 8 As shown, the hot liquid is vegetable oil, the input temperature of the vegetable oil is 200 degrees Celsius, and the heating column 501 and the series pipe 502 are made of high-speed steel. The liquid circulation heat conduction of vegetable oil has heating stability. Compared with electric heating, the heat output of electric heating fluctuates and is not stable enough.

[0038] like Figure 8 As shown, the heating column 501 is composed of a semi-cylinder. The two halves of the heating column 501 are locked together by countersunk bolts. When the heating column 501 is assembled, the heating channels 504 also form a sealed channel with each other. When the heating column 501 is assembled, the connection between the heating channels 504 is sealed. If the heating column 501 is deformed and leaks liquid, a rubber gasket is added in the middle of the heating column 501.

[0039] like Figure 1 , 4As shown in Figure 6, the opposing stirring mechanism includes an arch bridge 102 fixed to the top of the processing box 1. A planar bearing 8 is provided at the bottom end of the arch bridge 102. A turbine 801 is rotatably provided at the bottom end of the planar bearing 8. Several annularly arranged diverging bars 805 are provided at the bottom end of the turbine 801. The diverging bars 805 are inserted into the inner side of the heating column 501. A reverse stirring mechanism is also provided on the outer side of the turbine 801. The turbine 801 and its bottom diverging bars 805 are inserted into the oil sand for stirring, which increases the heat conduction efficiency during the stirring process.

[0040] like Figure 5 As shown, the reverse stirring mechanism includes a reverse ring 6. A retaining ring 103 matching the reverse ring 6 is provided on the inner side of the processing box 1. The reverse ring 6 is pressed onto the retaining ring 103 by its own gravity. Stirring strips 602 are arranged in a ring on the inner side wall of the reverse ring 6. The stirring strips 602 are inserted between the heating column 501 and the diverging strip 805. The reverse ring 6 is connected to the turbine 801 through a linkage assembly. The reverse ring 6 and the stirring strips 602 at its bottom end will insert into the oil sand to perform reverse stirring. This relative stirring increases the heat exchange efficiency and saves processing time.

[0041] like Figure 5 As shown, the linkage assembly includes a stirring motor 803 fixed to the side wall of the arch bridge 102. A worm gear 802 is installed at the output end of the stirring motor 803. The worm gear 802 and the turbine 801 mesh with each other. A vertical bevel gear 804 is also provided at the end of the worm gear 802. A mounting plate 7 is provided at the top of the processing box 1. A horizontal bevel gear 701 is rotatably provided at the bottom end of the mounting plate 7. The horizontal bevel gear 701 and the vertical bevel gear 804 mesh with each other. A rubber column 702 is provided at the bottom end of the horizontal bevel gear 701. The rubber column 702 is attached to the side wall of the friction ring 601. The stirring motor 803 drives the worm gear 802 and the turbine 801 to rotate together. The vertical bevel gear 804 at the end of the worm gear 802 drives the horizontal bevel gear 701 and the rubber column 702 to rotate. The rubber column 702 is attached to the friction ring 601 and drives the reverse ring 6 to rotate, thus achieving the effect of linkage stirring.

[0042] like Figure 9 As shown, rubber pads are provided on the side walls of the rubber column 702 and the friction ring 601. The pressure between the rubber pads is maintained between thirty and fifty Newtons, and the pressure between the rubber column 702 and the friction ring 601 is maintained within a certain range to prevent slippage between the rubber column 702 and the friction ring 601.

[0043] like Figure 9As shown, the high-speed cooling mechanism includes a cold air pump 403. A dispersion channel 404 is installed at the output end of the cold air pump 403. The port of the dispersion channel 404 is aligned with the bottom of the two cooling boxes 4. The cold air pump 403 is connected to cold air, which is dry ice vaporization gas. The discharge pump 2 extracts the asphalt layer of melted oil sand. The discharge pump 2 pushes the slurry asphalt into the cooling box 4 through the slurry pipe 201. At this time, the cold air pump 403 draws cold air and blows it onto the cooling box 4. The asphalt inside the cooling box 4 will cool down and solidify rapidly. The electric push rod 401 drives the two cooling boxes 4 to move up and down in turn. When the cooling box 4 moves, the solid asphalt will detach from the inner wall of the cooling box 4 and then the whole piece of asphalt will be lifted up.

[0044] like Figure 9 As shown, a cooling groove 402 is provided at the bottom of the cooling box 4. The material of the cooling groove 402 is aluminum. The distance between the cooling groove 402 and the internal chamber of the cooling box 4 is two millimeters. When cold air is injected into the cooling groove 402, heat exchange will be carried out quickly. The cooling groove 402 increases the heat exchange area and saves heat exchange time.

[0045] Includes the following steps:

[0046] S1. The oil sand material is fed into the processing box 1, and then hot vegetable oil is connected to the connecting pipe 503. The heat of the vegetable oil is transferred to the heating column 501, and the heating column 501 transfers the heat to the oil sand material. As a result, the temperature of the oil sand will reach 200 degrees Celsius, and the asphalt material in the oil sand will liquefy. At the same time, the sand and soil will not melt. Since the density of the sand and soil is greater than that of the asphalt, they will settle at the bottom of the processing box 1, thus achieving the function of asphalt separation and facilitating the subsequent extraction of asphalt material.

[0047] S2. While the oil sand material is being heated, the stirring motor 803 drives the worm gear 802 and the turbine 801 to rotate together. The diverging bar 805 at the bottom of the turbine 801 stirs the oil sand material in the forward direction. The vertical bevel gear 804 at the end of the worm gear 802 drives the horizontal bevel gear 701 and the rubber column 702 to rotate. The rubber column 702 is attached to the friction ring 601 and drives the reverse ring 6 to rotate. The stirring bar 602 at the bottom of the reverse ring 6 drives the oil sand to stir in the reverse direction, which can increase the heat conduction efficiency of the stirred oil sand.

[0048] S3. The discharge pump 2 extracts the asphalt layer of melted oil sand. The discharge pump 2 pushes the slurry asphalt into the cooling box 4 through the slurry pipe 201. At this time, the cold air pump 403 draws cold air and pushes it into the cooling tank 402. The asphalt inside the cooling box 4 will cool down and solidify quickly. The electric push rod 401 drives the two cooling boxes 4 to move up and down in turn. When the cooling box 4 moves, the solid asphalt will detach from the inner wall of the cooling box 4 and then the whole piece of asphalt will be lifted up.

[0049] Working principle: The oil sand material is fed into the processing chamber 1, and then hot vegetable oil is connected to the connecting pipe 503. The heat of the vegetable oil is transferred to the heating column 501, which in turn transfers the heat to the oil sand material. The temperature of the oil sand reaches 200 degrees Celsius, causing the asphalt material in the oil sand to liquefy. Meanwhile, the sand and soil do not melt. Since the density of the sand and soil is greater than that of the asphalt, they settle at the bottom of the processing chamber 1, achieving asphalt separation and facilitating subsequent extraction of the asphalt material. The vegetable oil heating method also offers a certain degree of safety. The liquid circulation heat conduction of vegetable oil provides stable heating compared to electric heating, which has fluctuating heat output. During assembly, the connection between heating channels 504 is sealed. If the heating column 501 deforms and leaks, a rubber gasket is added in the middle. The turbine 801 and its bottom-end radiating bar 805 are inserted into the oil sand for stirring, increasing heat conduction efficiency. The reverse ring 6 and its bottom-end stirring bar 602 are inserted into the oil sand for reverse stirring. The mixing operation, with its relative stirring, increases heat exchange efficiency and saves processing time. The stirring motor 803 drives the worm gear 802 and turbine 801 to rotate together. The vertical bevel gear 804 at the end of the worm gear 802 drives the horizontal bevel gear 701 and rubber column 702 to rotate. The rubber column 702, in contact with the friction ring 601, drives the reverse ring 6 to rotate, achieving a coordinated stirring effect. The pressure between the rubber column 702 and the friction ring 601 is maintained within a certain range to prevent slippage. The discharge pump 2... The asphalt layer of molten oil sand is extracted, and the discharge pump 2 pushes the slurry asphalt into the cooling box 4 through the slurry pipe 201. At this time, the cold air pump 403 draws cold air and blows it onto the cooling box 4. The asphalt inside the cooling box 4 will cool down and solidify quickly. The electric push rod 401 drives the two cooling boxes 4 to move up and down in turn. When the cooling box 4 moves, the solid asphalt will detach from the inner wall of the cooling box 4. Then the whole piece of asphalt is lifted up. When the cold air rushes into the cooling tank 402, it will quickly exchange heat. The cooling tank 402 increases the heat exchange area and saves heat exchange time.

Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.

S2. While the oil sand material is being heated, the stirring motor (803) drives the worm (802) and turbine (801) to rotate together. The diverging bar (805) at the bottom of the turbine (801) stirs the oil sand material in the forward direction. The vertical bevel gear (804) at the end of the worm (802) drives the horizontal bevel gear (701) and rubber column (702) to rotate. The rubber column (702) adheres to the friction ring (601) and drives the reverse ring (6) to rotate. The stirring bar (602) at the bottom of the reverse ring (6) drives the oil sand to stir in the reverse direction, which can increase the heat conduction efficiency of the stirred oil sand. S3. The discharge pump (2) extracts the asphalt layer of the melted oil sand. The discharge pump (2) pushes the slurry asphalt into the cooling box (4) through the slurry pipe (201). At this time, the cold air pump (403) draws cold air and pushes it into the cooling tank (402). The asphalt inside the cooling box (4) will cool down and solidify quickly. The electric push rod (401) drives the two cooling boxes (4) to move up and down in turn. When the cooling box (4) moves, the solid asphalt will be separated from the inner wall of the cooling box (4), and then the whole piece of asphalt will be lifted up.
