Description

Technical Field

[0001] This invention belongs to the field of shale oil heating and upgrading technology, and specifically relates to a shale oil heating and upgrading reaction device. Background Technology

[0002] Shale oil thermal upgrading involves heating shale oil rock samples in the formation using heated wells to convert heavy hydrocarbons retained in the formation into light hydrocarbons. At the same time, unconverted solid organic matter is pyrolyzed into oil and gas before being extracted. The amount of oil and gas generated by pyrolysis is a difficult problem and challenge in shale oil upgrading and extraction research. Usually, the oil yield of samples from the area needs to be tested before shale oil extraction.

[0003] The main method for simulating the thermal refining process of shale oil rock samples in the laboratory is to heat the rock samples in a heating container to simulate the process. The experimental data is then used to determine the oil content of the shale oil rock samples in their original underground state, which is more conducive to the exploration and exploitation of shale oil. However, the existing heating devices have uneven heating effects, resulting in poor heating of rock samples far from the heating source, which affects the experimental results. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a shale oil heating and reforming reaction device that can drive a drive motor to feed and transport a placement basket, facilitating the handling of rock samples. This also prevents the shale oil rock samples from breaking upon entering the heating tank, thus reducing the oil yield. Furthermore, during the heating and reforming of the shale oil rock samples in the heating tank, the drive motor rotates the placement basket, ensuring that microwaves act uniformly on the rock samples, thereby improving the heating effect and the rate of the reforming reaction.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A shale oil heating and reforming reactor includes a heating tank and two microwave generators. The two microwave generators are symmetrically mounted on the side of the heating tank. A resonant cavity is installed inside the heating tank. Waveguides connected to the two microwave generators are installed inside the heating tank. A drive motor is installed at the lower end of the heating tank. The output end of the drive motor is driven by a rotating shaft that is rotatably connected to the heating tank. A threaded rod is fixedly connected to the upper end of the rotating shaft. Several sliding grooves are formed on the inner wall of the heating tank. Sliding blocks are slidably connected to the sliding grooves. An annular groove communicating with the sliding grooves is formed inside the heating tank. A placement basket is fixedly connected to the sliding block. The basket is equipped with a rebound mechanism. An insulating empty barrel is fixedly connected to the center inside the basket. A limit block is fixedly connected to the lower end of the insulating empty barrel. A drive block matching the limit block is fixedly connected to the side of the rotating shaft. A threaded ring that is threadedly connected to a threaded rod is fixedly connected to the lower side inside the insulating empty barrel. A reflection mechanism is installed on the upper end of the threaded ring. A sealing cover is installed on the upper end of the heating tank. A radiation shield is fixedly connected to the lower end and side of the heating tank. A water outlet is opened through the lower end of the heating tank. An electromagnetically controlled water outlet pipe is connected to the upper side of the radiation shield. An electromagnetically controlled air outlet pipe is installed on the side of the heating tank. A feeding mechanism is installed on the basket.

[0007] The reflection mechanism includes a mounting ring fixedly connected to the upper end of the threaded ring. Several resonant cavity plates are rotatably mounted on the upper end of the mounting ring. The resonant cavity plates are chamfered on the side close to each other and then abut against each other. Several first springs are symmetrically mounted on the side of the resonant cavity plates close to the mounting ring. An adjustment component is mounted on the lower end of the sealing cover.

[0008] The adjustment assembly includes an abutment post, which is installed at the lower end of the sealing cover and is located between the insulating empty barrel and the resonant cavity plate.

[0009] The lower end of the sealing cap is provided with a T-shaped annular groove. An internal toothed ring is fixedly connected to the inner side of the T-shaped annular groove. A ratchet is slidably connected to the upper side of the T-shaped annular groove. Several pawls that mesh with the ratchet are elastically hinged inside the T-shaped annular groove. A gear that meshes with the internal toothed ring is fixedly connected to the lower end of the ratchet. The abutment post is fixedly connected to the lower end of the gear. The inner side of the insulating empty barrel is fixedly connected with meshing teeth that mesh with the gear.

[0010] The feeding mechanism includes a feeding basket with a through groove that matches the insulating empty barrel, and a placement basket with an opening that matches the feeding basket. A locking pin assembly is installed between the feeding basket and the placement basket.

[0011] A baffle is slidably connected inside the through groove.

[0012] The feeding basket has an inclined surface on the side near the through groove.

[0013] The rebound mechanism includes several second springs, and the upper ends of the several second springs are fixedly connected to an L-shaped ring plate that is slidably connected to the heating tank.

[0014] This invention enables the feeding and conveying of the placement basket via a drive motor, facilitating the handling of rock samples. It also prevents shale oil rock samples from breaking upon entering the heating tank, thus reducing the oil yield. Furthermore, when the shale oil rock samples are being heated and modified in the heating tank, the drive motor rotates the placement basket, ensuring that microwaves are applied evenly to the rock samples, thereby improving the heating effect and the rate of the modification reaction.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1:

[0030] like Figure 1-9 As shown, a shale oil heating and reforming reactor of the present invention includes a heating tank 1, two microwave generators 11, the two microwave generators 11 being symmetrically mounted on the side of the heating tank 1, a resonant cavity 12 being installed inside the heating tank 1, a waveguide 111 connected to the two microwave generators 11 being installed inside the heating tank 1, a drive motor 13 being installed at the lower end of the heating tank 1, a rotating shaft 14 being rotatably connected to the output end of the drive motor 13, a threaded rod 15 being fixedly connected to the upper end of the rotating shaft 14, a plurality of sliding grooves 16 being formed on the inner wall of the heating tank 1, a slider 161 being slidably connected to the plurality of sliding grooves 16, an annular groove 162 communicating with the plurality of sliding grooves 16 being formed inside the heating tank 1, and a placement basket 17 being fixedly connected to the slider 161. A rebound mechanism is installed at the lower part of the heating tank 1. An insulating empty barrel 18 is fixedly connected to the center of the placement basket 17. A limit block 181 is fixedly connected to the lower end of the insulating empty barrel 18. A drive block 182 matching the limit block 181 is fixedly connected to the side of the rotating shaft 14. A threaded ring 19 that is threaded to the threaded rod 15 is fixedly connected to the lower side of the inside of the insulating empty barrel 18. A reflection mechanism is installed at the upper end of the threaded ring 19. A sealing cover 20 is installed at the upper end of the heating tank 1. A radiation shielding plate 21 is fixedly connected to the lower end and the side of the heating tank 1. A water outlet hole is opened through the lower end of the heating tank 1. An electromagnetically controlled water outlet pipe 22 is connected to the upper side of the radiation shielding plate 21. An electromagnetically controlled air outlet pipe 23 is installed on the side of the heating tank 1. A feeding mechanism is installed in the placement basket 17.

[0031] When the sealing cap 20 is sealed to the heating tank 1, it abuts against the insulating empty barrel 18, which in turn causes the insulating empty barrel 18 to drive the placement basket 17 to compress the rebound mechanism downward, thereby causing the slider 161 to be located inside the annular groove 162, and the threaded ring 19 to release its contact with the threaded rod 15; when the sealing cap 20 is released from its sealing connection with the heating tank 1, the rebound force of the rebound mechanism will drive the placement basket 17 to move upward, thereby causing the slider 161 to be located inside the sliding groove 16, and the threaded ring 19 to contact the threaded rod 15. Thus, when the threaded rod 15 rotates, under the limiting action of the slider 161, the threaded ring 19 and the placement basket 17 will move upward, thereby facilitating the feeding and discharging of the placement basket 17;

[0032] When feeding is required, the drive motor 13 drives the rotating shaft 14 and the threaded rod 15 to rotate. At this time, since the sealing cover 20 is open, the threaded ring 19 abuts against the threaded rod 15 under the action of the spring mechanism, and the slider 161 is located inside the groove 16. Therefore, when the drive motor 13 drives the threaded rod 15 to rotate, it will drive the placement basket 17 and the slider 161 to move upward, thereby causing the placement basket 17 to leak out of the heating tank 1. This allows shale oil to easily enter the heating tank 1. After the shale oil is added, the drive motor 13 is driven to rotate in the opposite direction, which causes the threaded rod 15 to drive the placement basket 17 into the heating tank 1 until the threaded ring 19 moves downward and connects with the threaded rod 15. Then the drive motor 13 is turned off. At this time, the placement basket 17 abuts against the rebound mechanism and then the sealing cover 20 is closed. As the sealing cover 20 moves the placement basket 17 downward, the slider 161 enters the annular groove 162 and the limiting block 181 moves downward to match the position of the driving block 182. After the sealing cover 20 is sealed and connected to the heating tank 1, the two microwave generators 11 and the drive motor 13 are started. The microwave generators 11 and the waveguide 111 work together to guide microwaves into the resonant cavity 12. When the drive motor 13 works, it drives the rotating shaft 14 and the drive block 182 to rotate, which in turn drives the limiting block 181 to rotate. When the limiting block 181 rotates, it drives the insulating empty barrel 18 and the placement basket 17 to rotate. Since the slider 161 is located in the annular groove 162, the sliding cover 20 moves the placement basket 17 downward. Inside the 2nd cavity, the threaded ring 19 is located on the circumference of the rotating shaft 14 and does not contact the threaded rod 15. Therefore, the placement basket 17 can only rotate under the action of the limiting block 181 and the driving block 182, thereby causing the placement basket 17 to rotate and heat the shale oil rock sample inside. At the same time, the reflective mechanism installed at the center can reflect microwaves, superimposing them to generate standing waves to heat the inside. Since the energy is highest at the peak of the standing wave, the rotating placement basket 17 can make the peak of the standing wave act evenly on the rock sample, increasing the heating effect of microwaves on the rock sample. At the same time, the reflective mechanism can reflect the microwaves transmitted by the waveguide 111 to the side wall of the resonant cavity 12, and then reflect them again. This will improve the microwave reflection effect of the reflective mechanism, thereby increasing the standing wave. The heating effect on the rock sample; after completion, the position of the slider 161 is adjusted by the drive motor 13 to align it with the slide 16, and then the sealing cover 20 is opened. At this time, the rebound mechanism will drive the placement basket 17 to move upward under the action of the rebound force, thereby causing the slider 161 to enter the slide 16 and align the threaded end of the threaded rod 15 with the threaded end of the threaded ring 19. Then, the drive motor 13 can drive the threaded rod 15 to drive the placement basket 17 to move upward. The aqueous solution generated after heating and modification flows into the radiation shielding plate 21 from the water outlet hole, and then the aqueous solution is collected by connecting to the water outlet pipe 22 through the external equipment. The generated water vapor and oil gas are introduced into the subsequent processing equipment for treatment through the gas outlet pipe 23.

[0033] This invention enables the placement basket 17 to be fed and transported by the drive motor 13, facilitating the handling of rock samples. It also prevents shale oil rock samples from breaking when entering the heating tank 1, thus affecting the oil yield. Furthermore, when the shale oil rock samples are heated and modified in the heating tank 1, the drive motor 13 drives the placement basket 17 to rotate, allowing microwaves to act evenly on the rock samples, improving the heating effect and the rate of the modification reaction.

[0034] Example 2:

[0035] Based on Embodiment 1, a further improvement is made to the reflection mechanism, which includes a mounting ring 30 fixedly connected to the upper end of the threaded ring 19. Several resonant cavity plates 31 are rotatably mounted on the upper end of the mounting ring 20. The resonant cavity plates 31 are chamfered on the side close to each other and then abut against each other. Several first springs 32 are symmetrically mounted on the side of the resonant cavity plates 31 close to the mounting ring 30. An adjustment component is mounted on the lower end of the sealing cover 20. When the microwave generator 11 and the waveguide 111 deliver microwaves into the resonant cavity 12, the microwaves will act on the sides of the resonant cavity plates 31, and then reflect the microwaves back to the inner wall of the resonant cavity 12. This cycle will generate standing waves to heat and modify the rock sample. When the placement basket 17 rotates, it will drive the resonant cavity plates 31 to rotate, and then the microwaves transmitted by the waveguide 111 will act on the surface of the resonant cavity plates 31 for reflection. At the same time, the adjustment component can adjust the angle of the resonant cavity plates 31 during the rotation of the resonant cavity plates 31, thereby adjusting the direction of microwave reflection, which can increase the range of microwave action.

[0036] The adjustment assembly includes an abutment post 33, which is installed at the lower end of the sealing cover 20 and located between the insulating empty barrel 18 and the resonant cavity plate 31. The abutment post 33 is positioned close to the resonant cavity plate 31 but does not abut against its center. This allows the resonant cavity plate 31 to rotate so that its side abuts against the abutment post 33, causing it to deflect against the first spring 32 after being subjected to the abutment force of the post 33. This adjusts the reflection angle of the resonant cavity plate 31 until the next resonant cavity plate 31 abuts against the post 33. Then, it is pushed by the arc surface of the post 33 and flips again against the action of the first spring 32. This changes the reflection angle of the resonant cavity plate 31, thereby increasing the microwave reflection range.

[0037] The lower end of the sealing cover 20 has a T-shaped annular groove 34. An internal toothed ring 35 is fixedly connected to the inner side of the T-shaped annular groove 34. A ratchet 36 is slidably connected to the upper side of the T-shaped annular groove 34. Several pawls 361 that mesh with the ratchet 36 are elastically hinged inside the T-shaped annular groove 34. A gear 37 that meshes with the internal toothed ring 35 is fixedly connected to the lower end of the ratchet 36. An abutment post 33 is fixedly connected to the lower end of the gear 37. The inner side of the insulating empty barrel 18 has meshing teeth 38 that mesh with the gear 37. When sealed to the heating tank 1, the abutment post 33 can be inserted between the insulating empty barrel 18 and the resonant cavity plate 31. Then, the drive motor 13 drives the insulating empty barrel 18 to rotate in the direction that matches the ratchet 36 and the pawl 361, so that the ratchet 36 can overcome the elastically hinged pawl 361 to rotate. At the same time, the insulating empty barrel 18 will drive the meshing teeth 38 to rotate, thereby causing the rotating meshing teeth 38 to move closer to the gear 37. In this way, when the meshing teeth 38 abut against the gear 37, they mesh with the gear 37. This drives gear 37 to rotate, which in turn causes gear 37 to drive the abutment post 33 and ratchet 36 to rotate in the same direction as the insulating empty barrel 18 until the meshing teeth 38 disengage from gear 37, and gear 37, abutment post 33, and ratchet 36 come to a stop. At the same time, pawl 361 can prevent ratchet 36 from reversing. Moreover, during the rotation of abutment post 33, its position changes, thereby changing the position of the resonant cavity plate 31's reflection angle. At the same time, the rotation of abutment post 33 does not affect the abutment post 33's contact with the resonant cavity plate 31, and the ratchet 36 and pawl 361 prevent abutment post 33 from rotating in the opposite direction when it contacts the resonant cavity plate 31. In this way, the position of abutment post 33 inside the heating tank 1 can be continuously adjusted by adjusting the position of the resonant cavity plate 31, thereby adjusting the reflection angle of different resonant cavity plates 31, increasing the reflection range of resonant cavity plates 31 at different positions, thereby increasing the heating effect of microwaves on rock samples and improving the efficiency of the modification reaction.

[0038] The feeding mechanism includes a feeding basket 39, which has a through groove that matches the insulating empty barrel 18. A placement basket 17 has an opening that matches the feeding basket 39. A locking pin assembly is installed between the feeding basket 39 and the placement basket 17. During discharge, waste material is moved to both sides to leak out of the through groove. Then, the locking pin assembly is released, causing the feeding basket 39 to abut against the side wall of the insulating empty barrel 17, which in turn rotates the feeding basket 39, causing it to flip and tilt its opening, allowing it to slide out of the through groove. This facilitates disassembly of the feeding basket 39 for waste disposal. Disassembly also allows for easy cleaning of the interior of the heating tank 1 and the placement basket 17 for future use. During feeding, the feeding basket 39 is positioned in a V-shape to hold the rock sample. People are piled up inside the feeding basket 39, and then the feeding basket 39 moves so that its through groove abuts against the insulated empty barrel 18 and the placement basket 17. This allows the feeding basket 39 to slowly rotate until it is parallel to the placement basket 17. Then the locking pin assembly is connected. Due to the characteristics of oil shale, it is brittle and easily broken. Therefore, it is very easy to break it when feeding oil shale. After it is broken, the space between the small oil shale particles is small, resulting in poor air permeability between the particles. This leads to the heat not being evenly transferred to the oil shale particles, affecting the heating rate. Therefore, setting the feeding basket 39 at an incline can avoid the rock sample from being put into the placement basket 17 from a height, which would cause it to break and affect the heating rate. At the same time, the disassembled feeding basket 39 can facilitate the cleaning of the inside of the heating tank 1.

[0039] A baffle 40 is slidably connected inside the through groove; the baffle 40 can act as abutment against the feeding basket 39 when feeding, so that the feeding basket 39 is in an inclined "V" shape to facilitate feeding. When discharging, the baffle 40 slides into the feeding basket 39, so that the feeding basket 39 passes over the insulating empty barrel 18 and the side of the feeding basket 39 away from the placement basket 17 tilts downward, which is more convenient for discharging; the feeding basket 39 has an inclined surface 41 on the side near the through groove.

[0040] The rebound mechanism includes several second springs 42, the upper ends of which are all fixedly connected to an L-shaped ring plate 43 that is slidably connected to the heating tank 1. In its natural state, the second springs 42 can drive the L-shaped ring plate 43 to slide upward, thereby moving the lower end of the L-shaped ring plate 43 away from the heating tank 1. At the same time, it can also support the placement basket 17 and the rock sample. When the sealing cover 20 is closed downward, the sealing cover 20 will drive the insulating empty barrel 18 and the placement basket 17 to move downward, thereby driving the L-shaped ring plate 43 to overcome the downward movement of the second springs 42. The movement causes the L-shaped ring plate 43 to come into contact with the heating tank 1, thus positioning the slider 161 inside the ring groove 162, and the threaded ring 19 to contact the threaded rod 15. After completion, the position of the slider 161 is adjusted by the drive motor 13 to align it with the groove 16, and then the sealing cover 20 is opened. At this time, several second springs 42 will drive the placement basket 17 upward under the action of the rebound force, thereby causing the slider 161 to enter the groove 16 and aligning the threaded end of the threaded rod 15 with the threaded end of the threaded ring 19.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
