Description

Technical Field

[0001] This invention relates to the fields of petrochemical and solid waste resource utilization technology, specifically to a conveyor for processing petroleum waste into asphalt raw materials. Background Technology

[0002] With the continuous development of the petrochemical industry, a large amount of oily solid waste is generated during production, storage, and transportation. This mainly includes tank sludge, oily sludge from refineries, and heavy oil residue. These petroleum wastes are complex in composition, typically consisting of a mixture of water, oil, asphaltenes, waxes, and solid particles (such as silt and catalyst powder), exhibiting high viscosity, high pour point, and easy solidification. Traditional treatment methods, such as direct landfilling or incineration, are not only costly and wasteful of resources, but also pose significant environmental risks.

[0003] On the other hand, as an important material for infrastructure construction, the market demand for asphalt continues to grow. Using petroleum waste as an alternative raw material for asphalt production can not only effectively alleviate the environmental pressure on the petrochemical industry and achieve the "reduction, resource utilization, and harmless treatment" of solid waste, but also reduce the raw material cost of asphalt production. It is a circular economy path with great development prospects.

[0004] However, the stable and continuous transport of petroleum waste to the asphalt reaction unit is a key bottleneck in realizing this resource utilization process. Currently, conventional conveying equipment is commonly used, which easily leads to the following problems: 1. Petroleum waste has a complex composition, often containing solid particles (mud, paraffin wax, asphalt lumps), high-viscosity liquids, and impurities. During the transport process, bridging and severe blockages can easily form at the silo outlet, conveying pipeline, or inside the equipment, causing production interruptions, requiring frequent shutdowns for cleaning, and resulting in extremely low efficiency.

[0005] 2. The heavy oil and asphalt components in the waste material are highly adhesive and will continuously adhere to the inner wall of the conveying equipment. As the adhesive layer gradually thickens, it not only reduces the effective conveying space and decreases conveying efficiency, but also requires expensive chemical cleaning or mechanical cleaning due to solidification and scaling, resulting in high maintenance costs.

[0006] Therefore, this invention proposes a conveyor for processing petroleum waste into asphalt raw materials. Summary of the Invention

[0007] The purpose of this invention is to provide a conveyor for processing petroleum waste into asphalt raw materials, so as to solve the problems mentioned in the background art.

[0010] Preferably, a crushing box is fixedly connected to the discharge port, and a hopper is detachably connected to the upper end of the crushing box. A first conveyor belt is rotatably connected to the end of the rotating shaft near the motor, and a left-turning pipe is rotatably connected to the end of the first conveyor belt away from the rotating shaft. There are two left-turning pipes, and one end of each left-turning pipe extends through into the crushing box and is rotatably connected to the crushing box. The end of each left-turning pipe extending into the crushing box is fixedly connected to a central crushing cylinder. Crushing blades are densely and evenly fixedly connected to the outer wall of each central crushing cylinder, and the crushing blades on the two central crushing cylinders are staggered.

[0011] Preferably, each of the central crushing cylinders has a right-turning pipe fixedly connected to the end away from the left-turning pipe. One end of the right-turning pipe extends through the side wall of the crushing chamber and is rotatably connected to the crushing chamber. A gear is fixedly connected to the end of each right-turning pipe extending out of the crushing chamber. The two gears mesh with each other, and a protective box is fitted around the outside of the gear. The protective box is fixedly connected to the side wall of the crushing chamber, and one end of the right-turning pipe extends through the protective box and is rotatably connected to the protective box.

[0012] Preferably, a steam box is placed on the operating platform, the steam box contains a steam generator, a water inlet is opened at the upper end of the steam box, a sealing plug is plugged into the water inlet, a first blower is fixedly connected to the side wall of the steam box, a steam chamber is opened in the conveying channel, and the other end of the first blower is connected to the steam chamber.

[0013] Preferably, the sidewall of the steam chamber near the rotating shaft is made of a heat-conducting material, the sidewall of the steam chamber away from the rotating shaft is made of a heat-insulating material, and both the left and right rotating pipes are made of heat-insulating materials.

[0014] Preferably, a first row is fixedly connected to the upper end face of the conveying channel, the lower end of the first row extends into the steam chamber and communicates with the steam chamber, one end of the right-turning pipe extends into the first row and is rotatably connected to the first row, a second blower is fixedly connected to the upper end of the steam box, the upper end of the second blower is fixedly connected to the second row, and the end of the left-turning pipe away from the central crushing cylinder is connected to the second row.

[0015] Preferably, the crushing box is provided with a guide plate, which is located below the central crushing cylinder and is inclined.

[0016] Preferably, a second conveyor belt is rotatably connected to the left-turning pipe, and a control rod is rotatably connected to the end of the second conveyor belt away from the left-turning pipe. The control rod extends through and is fixedly connected to a bearing. A vibrating box is embedded and fixedly connected inside the crushing box, and the bearing is embedded and fixedly connected inside the vibrating box. A T-shaped cylinder extends through and is slidably connected inside the vibrating box. One end of the T-shaped cylinder extending through the vibrating box is fixedly connected to a guide inclined plate. An inclined ring groove is formed inside the control rod, and one end of the control rod extends into the T-shaped cylinder. A protrusion is fixedly connected to the inner wall of the T-shaped cylinder, and the protrusion extends into and is drivenly connected to the inclined ring groove. A wear-resistant block is fixedly connected to the inner wall of the crushing box, and an impact block is fixedly connected to one end of the guide inclined plate. The wear-resistant block and the impact block correspond to each other.

[0017] Preferably, the inclined annular groove is a reciprocating wire groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention involves placing petroleum waste into a crushing box, starting a motor, and the motor's operation drives a rotating shaft through an output shaft. The rotating shaft drives a left rotating pipe connected to it through a first conveyor belt. The left rotating pipe drives a right rotating pipe through a central crushing cylinder. Gears meshing on the two right rotating pipes rotate, and the right rotating pipes on the two gears rotate. The two central crushing cylinders fixedly connected to the two right rotating pipes rotate. Since the two gears mesh and rotate in opposite directions, the two central crushing cylinders rotate in opposite directions, and the crushing blades on the two central crushing cylinders rotate in opposite directions. After the petroleum waste is placed into the crushing box, the two crushing blades rotating in opposite directions crush the petroleum waste. This crushing method can break large pieces of petroleum waste into small particles, thereby preventing large pieces of petroleum waste from accumulating during transportation, forming bridging phenomena and serious blockages, leading to production interruptions and the need for frequent shutdowns for cleaning.

[0019] 2. In this invention, the rotation of the left-hand rotating pipe drives the rotation of the control rod via the second conveyor belt. The inclined ring groove on the control rod rotates, and the protrusion rotates within the inclined ring groove along its trajectory. Due to the displacement caused by the inclination of the inclined ring groove, the T-shaped cylinder where the protrusion is located moves back and forth. As the control rod rotates rapidly, the T-shaped cylinder also moves back and forth rapidly. The guide inclined plate fixedly connected to the T-shaped cylinder also moves back and forth, generating dense vibration. After the petroleum waste is crushed into small particles by the crushing blade, it falls and is guided by the guide inclined plate through the discharge port into the lower conveying channel. The vibration of the guide inclined plate can prevent the falling petroleum waste particles from accumulating and forming an arched structure, which would cause serious blockage. In other words, the design of the guide inclined plate can guide the petroleum waste particles while promoting their flow into the conveying channel.

[0020] 3. The present invention, when the guide plate vibrates, the striking block fixedly connected to the guide plate vibrates, thereby continuously striking the wear-resistant block, causing the wear-resistant block and the outer wall of the crushing box fixedly connected to it to generate frequent small-amplitude vibrations, so as to prevent petroleum waste particles from sticking to the inner wall of the crushing box, and further prevent petroleum waste particles from forming an arched structure and causing blockage.

[0021] 4. The present invention drives the fixedly connected spiral blade to rotate by rotating the shaft, thereby conveying the petroleum waste particles that fall into the conveying channel in a spiral manner. When the spiral blade rotates, the spiral scraper fixedly connected to the outside of the spiral blade also rotates synchronously. The rotation of the spiral scraper scrapes the inner wall of the conveying channel to prevent substances with high viscosity characteristics, such as heavy oil and asphalt components, in the petroleum waste particles from sticking to the inner wall of the conveying channel.

[0022] 5. In this invention, sufficient water is injected into the steam box through the water inlet. The steam generator heats the water, and the water temperature gradually rises to produce steam. The steam carries extremely high temperature. The first blower operates to transport the steam in the steam box into the conveying channel. The steam in the conveying channel heats the inner wall of the conveying channel, thereby transferring heat to the conveying channel and making the conveying channel also have a high temperature. This keeps the high-viscosity substances in the petroleum waste particles, such as heavy oil and asphalt components, in a liquefied state, thereby reducing their viscosity, ensuring fluidity, and facilitating the conveying by the spiral blades.

[0023] 6. The design of the steam chamber with the side wall near the rotating shaft made of heat-conducting material and the side wall away from the rotating shaft made of heat-insulating material can effectively transfer as much heat of water vapor as possible to the conveying channel, so that the temperature in the conveying channel is always higher than the freezing point of the highly viscous substances in the petroleum waste particles, so that these substances always have fluidity and reduce their viscosity.

[0024] 7. The water vapor in the conveying channel of the present invention flows into the central crushing cylinder through the first row and the right-turning pipe, thereby heating the central crushing cylinder and the crushing blades on it. This allows the oil waste to be crushed while simultaneously liquefying the more viscous substances in the oil waste, reducing its viscosity. This prevents the oil waste from sticking to the central crushing cylinder and the crushing blades, and also prevents the oil waste from piling up below the crushing box after crushing, forming an arched structure and causing blockage.

[0025] 8. The present invention, by designing that both the left-turning tube and the right-turning tube are made of heat-insulating material, can prevent the gear on the right-turning tube from being affected by heat, thus affecting its service life, and can also prevent the heat inside the left-turning tube and the right-turning tube from dissipating and causing heat loss.

[0026] 9. In this invention, water vapor passes through the central crushing cylinder, then through the left-turning pipe and the second row, and is finally sent back to the steam box by the working second blower. After returning to the steam box through the above path, the water vapor's heat is reduced, but after returning to the steam box, the heat returns to the initial high temperature level, and then it is sent out by the first blower again, forming a water vapor cycle and a heat cycle. This reduces water loss and heat loss, and allows for long-term use after injecting water into the steam box. Subsequently, only intermittent water replenishment is needed.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 9 The present invention provides a technical solution: a conveyor for processing petroleum waste into asphalt raw materials, comprising a conveying channel 1, an operating platform 11 fixedly connected to one side of the bottom of the conveying channel 1, a motor 12 mounted on the operating platform 11, a bolt 13 threadedly connecting the motor 12 and the operating platform 11, a rotating shaft 14 fixedly connected to the output shaft of the motor 12, the rotating shaft 14 extending through the conveying channel 1 and rotatably connected relative to the conveying channel 1, a spiral blade 15 being wound around and fixedly connected to the side wall of the end of the rotating shaft 14 extending out of the conveying channel 1, and a discharge port 17 being provided on the conveying channel 1.

[0039] As an embodiment of the present invention, as shown in the figure, a spiral scraper 2 is fixedly connected to the side of the spiral blade 15 away from the rotating shaft 14, and the spiral scraper 2 has sharp corners on both sides.

[0040] During operation, the rotating shaft 14 rotates, driving the fixedly connected spiral blade 15 to rotate, thereby conveying the petroleum waste particles that fall into the conveying channel 1. When the spiral blade 15 rotates, the spiral scraper 2 fixedly connected to the outside of the spiral blade 15 also rotates synchronously. The rotation of the spiral scraper 2 scrapes the inner wall of the conveying channel 1 to prevent substances with high viscosity characteristics, such as heavy oil and asphalt components, in the petroleum waste particles from sticking to the inner wall of the conveying channel 1.

[0041] As an embodiment of the present invention, as shown in the figure, a crushing box 3 is fixedly connected to the discharge port 17, and a hopper 16 is detachably connected to the upper end of the crushing box 3. A first conveyor belt 31 is rotatably connected to the end of the rotating shaft 14 near the motor 12, and a left-turning pipe 32 is rotatably connected to the end of the first conveyor belt 31 away from the rotating shaft 14. There are two left-turning pipes 32, and one end of each left-turning pipe 32 extends through into the crushing box 3 and is rotatably connected to the crushing box 3. The end of each left-turning pipe 32 extending into the crushing box 3 is fixedly connected to a central crushing cylinder 33. Crushing blades 34 are densely and evenly fixedly connected to the outer wall of each central crushing cylinder 33, and the crushing blades 34 on the two central crushing cylinders 33 are staggered.

[0042] Each of the central crushing cylinders 33 has a right-turning pipe 4 fixedly connected to one end away from the left-turning pipe 32. One end of the right-turning pipe 4 extends through the side wall of the crushing box 3 and is rotatably connected to the crushing box 3. A gear 41 is fixedly connected to one end of each right-turning pipe 4 extending out of the crushing box 3. The two gears 41 mesh with each other, and a protective box 42 is fitted on the outside of the gear 41. The protective box 42 is fixedly connected to the side wall of the crushing box 3. One end of the right-turning pipe 4 extends through the protective box 42 and is rotatably connected to the protective box 42.

[0043] During operation, petroleum waste is placed into the crushing box 3, and the motor 12 is started. The motor 12 drives the rotating shaft 14 to rotate through the output shaft. The rotating shaft 14 drives the left rotating pipe 32 connected to it to rotate through the first conveyor belt 31. The left rotating pipe 32 drives the right rotating pipe 4 to rotate through the central crushing cylinder 33. The gears 41 meshing on the two right rotating pipes 4 rotate, and the right rotating pipes 4 on the two gears 41 rotate. The two central crushing cylinders 33 fixedly connected to the two right rotating pipes 4 rotate. Since the two gears 41 mesh and rotate in opposite directions, the two central crushing cylinders 33 rotate in opposite directions. The crushing blades 34 on the two central crushing cylinders 33 rotate in opposite directions. After the petroleum waste is placed into the crushing box 3, the two crushing blades 34 rotating in opposite directions crush the petroleum waste. Using this crushing method, large pieces of waste in the petroleum waste can be crushed into small particles, thereby preventing large pieces of petroleum waste from accumulating during the transportation process, forming bridging phenomena and serious blockages, which would lead to production interruptions and require frequent shutdowns for cleaning.

[0044] As an embodiment of the present invention, as shown in the figure, a steam box 5 is placed on the operating platform 11. The steam box 5 contains a steam generator 51. A water inlet is opened at the upper end of the steam box 5. A sealing plug is plugged into the water inlet. A first blower 52 is fixedly connected to the side wall of the steam box 5. A steam chamber 53 is opened in the conveying channel 1. The other end of the first blower 52 is connected to the steam chamber 53.

[0045] During operation, sufficient water is injected into the steam box 5 through the water inlet. The steam generator 51 heats the water, and the water temperature gradually rises to generate steam. The steam carries extremely high temperature. The first blower 52 operates to transport the steam in the steam box 5 into the conveying channel 1. The steam in the conveying channel 1 heats the inner wall of the conveying channel 1, thereby transferring heat to the conveying channel 1. This results in a high temperature inside the conveying channel 1, ensuring that high-viscosity substances in the petroleum waste particles, such as heavy oil and asphalt components, remain in a liquefied state, thus reducing their viscosity, ensuring fluidity, and facilitating the conveying by the spiral blades 15.

[0046] The high temperature inside the conveying channel 1 will also be transferred to the rotating shaft 14, spiral blade 15 and spiral hanging blade 2 inside the conveying channel 1, making them also hot, thereby preventing highly viscous substances in the petroleum waste particles from adhering to the rotating shaft 14, spiral blade 15 and spiral hanging blade 2 inside the conveying channel 1.

[0047] As an embodiment of the present invention, as shown in the figure, the side wall of the steam chamber 53 near the rotating shaft 14 is made of a heat-conducting material, and the side wall of the steam chamber 53 away from the rotating shaft 14 is made of a heat-insulating material. The left rotating pipe 32 and the right rotating pipe 4 are both made of heat-insulating material.

[0048] During operation, the side wall of the steam chamber 53 near the rotating shaft 14 is made of heat-conducting material, while the side wall of the steam chamber 53 away from the rotating shaft 14 is made of heat-insulating material. This design can effectively transfer as much heat from the water vapor as possible into the conveying channel 1, so that the conveying channel 1 always generates a temperature higher than the freezing point of the highly viscous substances in the petroleum waste particles, making these substances always fluid and reducing their viscosity.

[0049] The design of both the left-turning pipe 32 and the right-turning pipe 4 using heat-insulating materials can prevent the gear 41 on the right-turning pipe 4 from being affected by heat, thus affecting its service life. It can also prevent the heat inside the left-turning pipe 32 and the right-turning pipe 4 from dissipating and causing heat loss.

[0050] As an embodiment of the present invention, as shown in the figure, the upper end of the conveying channel 1 is fixedly connected to a first row 6, the lower end of the first row 6 extends into and communicates with the steam chamber 53, one end of the right-turning pipe 4 extends into and is rotatably connected to the first row 6, the upper end of the steam box 5 is fixedly connected to a second blower 61, the upper end of the second blower 61 is fixedly connected to a second row 62, and the end of the left-turning pipe 32 away from the central crushing cylinder 33 is connected to the second row 62.

[0051] During operation, the water vapor in the conveying channel 1 flows through the first row 6 and the right-turning pipe 4 into the central crushing cylinder 33, thereby heating the central crushing cylinder 33 and the crushing blades 34 on it. This allows the crushing of petroleum waste to simultaneously liquefy the more viscous substances in the petroleum waste, reducing its viscosity. This prevents the petroleum waste from sticking to the central crushing cylinder 33 and the crushing blades 34, and also prevents the petroleum waste from piling up below the crushing box 3 after crushing, forming an arched structure and causing blockage.

[0052] After passing through the central crushing cylinder 33, the steam then passes through the left-turning pipe 32 and the second row 62, and is finally sent back to the steam box 5 by the working second blower 61. After returning to the steam box 5 through the above path, the heat of the steam is reduced, and after returning to the steam box 5, the heat returns to the initial high temperature level. Then it is sent out by the first blower 52 again, forming a steam circulation and a heat circulation, so as to reduce water loss and heat loss. It can be used for a long time after water is injected into the steam box 5, and only intermittent water needs to be added in the middle.

[0053] As an embodiment of the present invention, as shown in the figure, a guide plate 7 is provided inside the crushing box 3. The guide plate 7 is located below the central crushing cylinder 33 and is inclined.

[0054] A second conveyor belt 8 is rotatably connected to the left-turning pipe 32. A control rod 81 is rotatably connected to the end of the second conveyor belt 8 away from the left-turning pipe 32. The control rod 81 extends through and is fixedly connected to a bearing 82. A vibrating box 85 is embedded and fixedly connected inside the crushing box 3. The bearing 82 is embedded and fixedly connected inside the vibrating box 85. A T-shaped cylinder 84 extends through and is slidably connected inside the vibrating box 85. One end of the T-shaped cylinder 84 extending through and out of the vibrating box 85 is fixedly connected to a guide inclined plate 7. An inclined ring groove 86 is opened inside the control rod 81. One end of the control rod 81 extends into the T-shaped cylinder 84. A protrusion 83 is fixedly connected to the inner wall of the T-shaped cylinder 84. The protrusion 83 extends into and is drivenly connected to the inclined ring groove 86.

[0055] During operation, the left-hand rotating pipe 32 rotates, driving the control rod 81 to rotate via the second conveyor belt 8. The inclined ring groove 86 on the control rod 81 rotates, and the protrusion 83 rotates within the inclined ring groove 86 along its trajectory. Due to the displacement caused by the inclination of the inclined ring groove 86, the T-shaped cylinder 84 where the protrusion 83 is located moves back and forth. As the control rod 81 rotates rapidly, the T-shaped cylinder 84 also moves back and forth rapidly. The guide inclined plate 7, which is fixedly connected to the T-shaped cylinder 84, also moves back and forth, generating dense vibrations. After being crushed into small particles by the crusher 34, the petroleum waste falls and, guided by the guide inclined plate 7, falls into the lower conveying channel 1 through the discharge port 17. The vibration of the guide inclined plate 7 can prevent the falling petroleum waste particles from accumulating and forming an arched structure, causing serious blockage. That is, the design of the guide inclined plate 7 can guide the petroleum waste particles while promoting the flow of the petroleum waste particles into the conveying channel 1.

[0056] Wear-resistant blocks 91 are fixedly connected to the inner wall of the crushing box 3, and a striking block 9 is fixedly connected to one end of the guide plate 7. The wear-resistant blocks 91 and the striking blocks 9 correspond to each other.

[0057] When the guide plate 7 vibrates, the striking block 9 fixedly connected to the guide plate 7 vibrates, thereby continuously striking the wear-resistant block 91. This causes the wear-resistant block 91, along with the outer wall of the crushing box 3 fixedly connected to it, to produce frequent small-amplitude vibrations, preventing petroleum waste particles from adhering to the inner wall of the crushing box 3. It can also further prevent petroleum waste particles from forming an arched structure that causes blockage.

[0058] As an embodiment of the present invention, as shown in the figure, the oblique annular groove 86 is a reciprocating wire groove.

[0059] During operation, a reciprocating thread groove is used instead of the inclined ring groove 86. The shape of the reciprocating thread groove is as follows: Figure 9 As shown in the right figure, this increases the vibration amplitude of the guide inclined plate 7, that is, the distance of displacement of the guide inclined plate 7, in order to achieve a better arch breaking effect.

[0060] Working Principle: During operation, petroleum waste is placed into the crushing box 3, and the motor 12 is started. The motor 12 drives the rotating shaft 14 to rotate through the output shaft. The rotating shaft 14 drives the left rotating pipe 32 connected to it to rotate through the first conveyor belt 31. The left rotating pipe 32 drives the right rotating pipe 4 to rotate through the central crushing cylinder 33. The gears 41 meshing on the two right rotating pipes 4 rotate, and the right rotating pipes 4 on the two gears 41 rotate. The two central crushing cylinders 33, which are fixedly connected to the two right rotating pipes 4, rotate. Since the two gears 41 mesh and rotate in opposite directions, the two central crushing cylinders 33 rotate in opposite directions. The crushing blades 34 on the two central crushing cylinders 33 rotate in opposite directions. After the petroleum waste is placed into the crushing box 3, the two crushing blades 34 rotating in opposite directions crush the petroleum waste. This crushing method can crush large pieces of petroleum waste into small particles, thereby preventing large pieces of petroleum waste from accumulating during the transportation process, forming bridging phenomena and serious blockages, which would lead to production interruptions and require frequent shutdowns for cleaning.

[0061] The hopper 16 is designed to facilitate the feeding of petroleum waste into the hopper 16, making operation easier.

[0062] The left-turning pipe 32 rotates, driving the control lever 81 to rotate via the second conveyor belt 8. The inclined ring groove 86 on the control lever 81 rotates, and the protrusion 83 rotates within the inclined ring groove 86 along its trajectory. Due to the displacement caused by the inclination of the inclined ring groove 86, the T-shaped cylinder 84 where the protrusion 83 is located moves back and forth. As the control lever 81 rotates rapidly, the T-shaped cylinder 84 also moves back and forth rapidly. The guide inclined plate 7, which is fixedly connected to the T-shaped cylinder 84, also moves back and forth, generating dense vibration. After being crushed into small particles by the crusher 34, the petroleum waste falls and, guided by the guide inclined plate 7, falls into the lower conveying channel 1 through the discharge port 17. The vibration of the guide inclined plate 7 can prevent the falling petroleum waste particles from accumulating and forming an arched structure, causing serious blockage. That is, the design of the guide inclined plate 7 can guide the petroleum waste particles and promote their flow into the conveying channel 1.

[0063] The reciprocating thread groove replaces the inclined ring groove 86. The shape of the reciprocating thread groove is as follows: Figure 9 As shown in the right figure, this increases the vibration amplitude of the guide inclined plate 7, that is, the distance of displacement of the guide inclined plate 7, in order to achieve a better arch breaking effect.

[0064] When the guide plate 7 vibrates, the striking block 9 fixedly connected to the guide plate 7 vibrates, thereby continuously striking the wear-resistant block 91. This causes the wear-resistant block 91, along with the outer wall of the crushing box 3 fixedly connected to it, to produce frequent small-amplitude vibrations, preventing petroleum waste particles from adhering to the inner wall of the crushing box 3. It can also further prevent petroleum waste particles from forming an arched structure that causes blockage.

[0065] The rotating shaft 14 drives the fixedly connected spiral blade 15 to rotate, thereby conveying the petroleum waste particles that fall into the conveying channel 1. When the spiral blade 15 rotates, the spiral scraper 2 fixedly connected to the outside of the spiral blade 15 also rotates synchronously. The rotation of the spiral scraper 2 scrapes the inner wall of the conveying channel 1 to prevent substances with high viscosity characteristics, such as heavy oil and asphalt components, in the petroleum waste particles from sticking to the inner wall of the conveying channel 1.

[0066] Sufficient water is injected into the steam box 5 through the water inlet. The steam generator 51 heats the water, and the water temperature gradually rises to produce steam. The steam carries extremely high temperature. The first blower 52 operates to transport the steam in the steam box 5 into the conveying channel 1. The steam in the conveying channel 1 heats the inner wall of the conveying channel 1, thereby transferring heat to the conveying channel 1 and making the conveying channel 1 also have a high temperature. This keeps the high-viscosity substances in the petroleum waste particles, such as heavy oil and asphalt components, in a liquefied state, thereby reducing their viscosity, ensuring fluidity, and facilitating the conveying by the spiral vane 15.

[0067] The high temperature inside the conveying channel 1 will also be transferred to the rotating shaft 14, spiral blade 15 and spiral hanging blade 2 inside the conveying channel 1, making them also hot, thereby preventing highly viscous substances in the petroleum waste particles from adhering to the rotating shaft 14, spiral blade 15 and spiral hanging blade 2 inside the conveying channel 1.

[0068] The design of the steam chamber 53 having a heat-conducting sidewall near the rotating shaft 14 and an insulating sidewall away from the rotating shaft 14 can effectively transfer as much heat from the steam as possible into the conveying channel 1, so that the conveying channel 1 always generates a temperature higher than the freezing point of the highly viscous substances in the petroleum waste particles, making these substances always fluid and reducing their viscosity.

[0069] The water vapor in the conveying channel 1 flows into the central crushing cylinder 33 through the first row 6 and the right-turning pipe 4, thereby heating the central crushing cylinder 33 and the crushing blades 34 on it. This allows the oil waste to be crushed while simultaneously liquefying the more viscous substances in the oil waste, reducing its viscosity. This prevents the oil waste from sticking to the central crushing cylinder 33 and the crushing blades 34, and also prevents the oil waste from piling up below the crushing box 3 after crushing, forming an arched structure and causing blockage.

[0070] The design of both the left-turning pipe 32 and the right-turning pipe 4 using heat-insulating materials can prevent the gear 41 on the right-turning pipe 4 from being affected by heat, thus affecting its service life. It can also prevent the heat inside the left-turning pipe 32 and the right-turning pipe 4 from dissipating and causing heat loss.

[0071] After passing through the central crushing cylinder 33, the steam then passes through the left-turning pipe 32 and the second row 62, and is finally sent back to the steam box 5 by the working second blower 61. After returning to the steam box 5 through the above path, the heat of the steam is reduced, and after returning to the steam box 5, the heat returns to the initial high temperature level. Then it is sent out by the first blower 52 again, forming a steam circulation and a heat circulation, so as to reduce water loss and heat loss. It can be used for a long time after water is injected into the steam box 5, and only intermittent water needs to be added in the middle.

[0072] When cleaning is required after use, simply continue to supply cleaning fluid into hopper 16. Due to the high temperature inside the conveyor, the highly viscous substances in the petroleum waste are liquefied, so the remaining highly viscous parts of the petroleum waste are also in a liquefied state. The cleaning fluid can easily wash away the petroleum waste particles and their highly viscous parts, making the subsequent cleaning and maintenance of this conveyor very convenient and practical.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
