Description

A multi-functional vehicle for the top of an anode calcining pot furnace Technical Field

[0001] This invention relates to the field of pot furnace technology, and more particularly to a multi-functional vehicle for the top of an anode calcination pot furnace. Background Technology

[0002] Calcined petroleum coke is a product of delayed petroleum coke after calcination, and it is an important raw material for the production of aluminum anodes and cathodes. Domestic demand for calcined petroleum coke has consistently grown faster than the international average, indicating a large market demand and significant overall economic benefits.

[0003] Currently, calcined petroleum coke in China is mainly produced through two methods: rotary kiln calcination and pot furnace calcination. Compared to rotary kilns, pot furnace calcination results in lower burn-off and higher calcination quality, therefore, pot furnace calcination remains the mainstream method for calcined coke production in China. A pot furnace consists of multiple vertical pots arranged in two rows. Each pot has a feed inlet at the top, with hoppers attached to the inlets. Adjacent hoppers are closely spaced, and feed is continuously added to the hoppers along the row direction by a belt conveyor or a dedicated feeding trolley. However, due to the inherent stickiness of delayed petroleum coke, it easily cokes and sticks upon entering the furnace at high temperatures, often leading to blockages at the feed inlets.

[0004] To address the above situation, the current method involves first shoveling the raw material out of the hopper and then using a steel rod to clear the blockage. However, due to the high temperature of the raw material and the considerable height of the hopper, manually shoveling the material is dangerous and difficult. Furthermore, the hopper is typically about 1.7 meters above the furnace surface, requiring the steel rod to be inserted at least 1 meter into the feed inlet during cleaning. This results in a longitudinal travel of three meters for the rod itself, necessitating a higher ceiling and indirectly increasing the plant height and costs. Since the coke at the feed inlet is quite hard, and the tip of the steel rod exerts significant impact when clearing the blockage, this method can easily damage the brickwork near the feed inlet. Additionally, because the steel rod can only clear the blockage longitudinally, it is ineffective at cleaning the side walls of the feed inlet. Summary of the Invention

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a multi-functional trolley for the top of an anode calcining pot furnace. By setting a sliding main frame and setting a material suction mechanism and a cleaning mechanism, the automatic integrated design of material suction and cleaning is realized, making the equipment flexible and improving cleaning efficiency.

[0006] A multi-functional vehicle for the top of an anode calcining pot furnace includes a main frame, which spans across the furnace top along the furnace width direction. The horizontal plane of the main frame serves as an operating platform. The main frame is slidably arranged along the furnace length direction. The operating platform is equipped with a row of material suction mechanisms and a row of cleaning mechanisms parallel to the furnace width direction. Both the material suction mechanisms and the cleaning mechanisms are arranged corresponding to the receiving hopper.

[0007] By integrating a suction mechanism and a cleaning mechanism on the main frame, an automated integrated design for suction and cleaning is achieved, avoiding the dangerous manual shoveling and cleaning operations, and improving cleaning efficiency. The main frame is sliding; upon detecting a blockage, the equipment is moved to the corresponding receiving hopper, aligning the suction mechanism with the hopper. After suction is complete, the equipment is moved to align the cleaning mechanism with the receiving hopper to complete the cleaning work. The equipment is flexible, occupies a small area, and has a low cost. The main frame includes an operating platform, providing workers with the means to observe the status of the receiving hopper's inlet, facilitating worker control over the cleaning process.

[0008] Furthermore, the cleaning mechanism includes a cleaning frame, a lifting motor, a lifting platform, a guide rail, a rotary motor, and a spiral cleaner. The cleaning frame is connected to the operating platform. The cleaning frame is provided with a guide rail in the vertical direction. The guide rail is connected to the lifting platform. The lifting motor is connected to the guide rail and is used to drive the guide rail to lift the lifting platform. The rotary motor is fixed to the lifting platform. The rotating end of the rotary motor is connected to the top of the spiral cleaner. The bottom end of the spiral cleaner is a spiral cutter head with a size corresponding to the feed inlet.

[0009] By setting the specific structure of the cleaning mechanism, the cleaning process is automated, replacing traditional manual operation. In addition, a spiral cleaner is set up. Compared with the steel bar poking, the spiral cleaner has a larger cleaning range and can clean the side wall of the feed inlet. Moreover, the rotating cleaning force is even, reducing accidental damage to the brick layer near the feed inlet.

[0010] Furthermore, the cleaning mechanism also includes an extension rod, the two ends of which are respectively matched with the rotating end of the rotary motor and the top of the spiral cleaner. The length of the extension rod is less than the distance between the lifting platform and the bottom surface of the cleaning frame when the lifting platform is at the top. The bottom surface of the cleaning frame is provided with a fixing clip, which is sleeved on the outside of the spiral cleaner. When the fixing clip is tightened, it fixes the position of the spiral cleaner.

[0011] By using an extension rod and a fixing clamp, the spiral cleaner can be lowered to its lowest position and fixed in place, while the rotary motor can be raised to its highest position. The extension rod is then connected between the spiral cleaner and the rotary motor before lowering the spiral cleaner again, thus reducing the overall height of the equipment and consequently reducing costs.

[0012] Furthermore, quick connectors are provided at both ends of the extension rod, the rotating end of the rotary motor, and the top of the spiral cleaner.

[0013] The extension rod can be quickly attached and detached by using a quick connector, which improves operational efficiency.

[0014] Furthermore, the extension rod is detachably connected to the cleaning frame. This detachable connection makes the extension rod easy to place and remove, while preventing it from accidentally falling when not in use.

[0015] Furthermore, the material suction mechanism includes a material suction pipe, a material suction lifting frame, and a material suction fan. One end of the material suction pipe is connected to the material suction fan, and the other end is located above the receiving hopper. The material suction lifting frame is connected to the operating platform and is used to drive the material suction pipe into or out of the receiving hopper.

[0016] By setting the specific structure of the material suction mechanism, automated material suction operation was achieved, replacing the traditional manual material shoveling, which reduced the risk factor and greatly improved efficiency.

[0017] Furthermore, it also includes a storage tank, which is set on the operating platform. The suction pipe is connected to the suction fan through the storage tank, and the storage tank is under negative pressure when suctioning.

[0018] By setting up storage tanks, the raw materials sucked up can be collected, reducing the pollution to the construction environment during the material suction stage.

[0019] Furthermore, the storage tank is equipped with a filter bag, and the output end of the storage tank is connected to the receiving hopper.

[0020] By setting up filter bags, the sucked raw materials are filtered, ensuring the smooth operation of the suction fan. The filtered raw materials are then injected into the receiving hopper, reducing the loss of raw materials during cleaning.

[0021] Furthermore, a series of suction mechanisms are connected to a storage tank, and each suction pipe is equipped with a suction pipe valve.

[0022] By connecting a single suction mechanism to only one storage tank, the number of devices is reduced, costs are lowered, and equipment flexibility is improved.

[0023] Furthermore, one suction mechanism has two sets of suction mechanisms, and one cleaning mechanism has two sets of cleaning mechanisms. By setting specific quantities, the equipment can be adapted to conventional pot furnace types.

[0024] The beneficial effects of this invention are as follows: This invention provides a multi-functional trolley for the top of an anode calcining pot furnace. By incorporating a material suction mechanism and a cleaning mechanism on the main frame, it achieves an automated integrated design for material suction and cleaning, avoiding the dangerous manual shoveling and cleaning operations, and improving cleaning efficiency. The main frame is sliding; upon detecting material blockage, the equipment can be moved to the corresponding receiving hopper, aligning the material suction mechanism with the hopper. After suction is complete, the equipment is moved to the cleaning mechanism, aligning it with the receiving hopper to complete the cleaning work. The equipment is flexible, occupies a small area, and has a low cost. The main frame has an operating platform, providing workers with the conditions to observe the status of the receiving hopper's inlet, facilitating worker control over the cleaning process.

[0025] The cleaning mechanism is equipped with a spiral cleaner. Compared to using a steel rod to pry open the surface, the spiral cleaner has a wider cleaning range, reaching the side walls of the feed inlet. Furthermore, the rotating cleaning action applies even force, reducing accidental damage to the brick layers near the feed inlet. An extension rod can also be connected between the spiral cleaner and the rotating motor before lowering the machine, reducing the overall height of the equipment and thus lowering costs.

Detailed Implementation

[0028] To better explain and facilitate understanding of the present invention, it will be described in detail below with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0029] As shown in Figures 1-4, a multi-functional vehicle for the top of an anode calcining tank furnace includes a main frame 1, which spans the furnace top along the furnace width direction. The horizontal plane of the main frame 1 serves as an operating platform. The main frame 1 is slidably arranged along the furnace length direction. The operating platform is equipped with a row of material suction mechanisms and a row of cleaning mechanisms parallel to the furnace width direction. Both the material suction mechanisms and the cleaning mechanisms are correspondingly arranged with the receiving hopper 18.

[0030] By incorporating a suction mechanism and a cleaning mechanism on the main frame 1, an automated integrated design for suction and cleaning is achieved, avoiding the dangerous manual shoveling and cleaning operations, and improving cleaning efficiency. The main frame 1 is a sliding design; upon detecting a blockage, the equipment is moved to the corresponding receiving hopper 18, aligning the suction mechanism with the hopper. After suction is complete, the equipment is moved to align the cleaning mechanism with the receiving hopper 18 to complete the cleaning work. The equipment is flexible, occupies a small area, and has a low cost. The main frame 1 includes an operating platform, providing workers with the means to observe the status of the feed inlet 19 of the receiving hopper 18, facilitating worker control over the cleaning process.

[0031] More specifically, the main frame 1 is equipped with a drive motor 10, which controls the main frame 1 to move along the length of the furnace at the top of the furnace.

[0032] Specifically, the cleaning mechanism includes a cleaning frame 8, a lifting motor 12, a lifting platform 13, a guide rail 14, a rotary motor 11, and a spiral cleaner 9. The cleaning frame 8 is connected to the operating platform. The cleaning frame 8 is provided with a guide rail 14 in the vertical direction. The guide rail 14 is connected to the lifting platform 13. The lifting motor 12 is connected to the guide rail 14 and is used to drive the guide rail 14 to lift the lifting platform 13. The rotary motor 11 is fixed to the lifting platform 13. The rotating end of the rotary motor 11 is connected to the top of the spiral cleaner 9. The bottom end of the spiral cleaner 9 is a spiral cutter head with a size corresponding to the feed inlet 19.

[0033] By setting the specific structure of the cleaning mechanism, the cleaning process is automated, replacing traditional manual operation. In addition, a spiral cleaner 9 is set up. Compared with the steel bar poking, the spiral cleaner 9 has a larger cleaning range and can clean the side wall of the feed inlet 19. Moreover, the rotating cleaning force is uniform, reducing accidental damage to the brick layer near the feed inlet 19.

[0034] Specifically, the cleaning mechanism also includes an extension rod 16, the two ends of which are matched with the rotating end of the rotary motor 11 and the top of the spiral cleaner 9, respectively. The length of the extension rod 16 is less than the distance between the lifting platform 13 and the bottom surface of the cleaning frame 8 when the lifting platform 13 is at the top. The bottom surface of the cleaning frame 8 is provided with a fixing clip 17, which is sleeved on the outside of the spiral cleaner 9. When the fixing clip 17 is tightened, it fixes the position of the spiral cleaner 9.

[0035] By setting the extension rod 16 and the fixing clamp 17, the spiral cleaner 9 can be fixed when it is lowered to the lowest point, and the rotary motor 11 can be raised to the highest point. After the extension rod 16 is connected between the spiral cleaner 9 and the rotary motor 11, it is lowered again, which reduces the overall height of the equipment and thus reduces the cost.

[0036] Specifically, quick connectors 15 are provided at both ends of the extension rod 16, the rotating end of the rotary motor 11, and the top of the spiral cleaner 9.

[0037] The quick connector 15 enables rapid installation and removal of the extension rod 16, improving operational efficiency.

[0038] Specifically, the extension rod 16 is detachably connected to the cleaning frame 8. By detachably connecting the extension rod 16 to the cleaning frame 8, the extension rod 16 is easy to put on and take off, while preventing the extension rod 16 from accidentally falling when not in use.

[0039] Specifically, the material suction mechanism includes a material suction pipe 2, a material suction lifting frame 3, and a material suction fan 5. One end of the material suction pipe 2 is connected to the material suction fan 5, and the other end is located above the receiving hopper 18. The material suction lifting frame 3 is connected to the operating platform and is used to drive the material suction pipe 2 into or out of the receiving hopper 18.

[0040] By setting the specific structure of the material suction mechanism, automated material suction operation was achieved, replacing the traditional manual material shoveling, which reduced the risk factor and greatly improved efficiency.

[0041] The lifting part of the suction mechanism can use existing technology, and there are no restrictions here. The suction pipe 2 can be made of flexible materials with telescopic function such as corrugated pipe, so as to save space.

[0042] Specifically, it also includes a storage tank 6, which is set on the operating platform. The suction pipe 2 is connected to the suction fan 5 through the storage tank 6. The storage tank 6 is under negative pressure when suctioning.

[0043] By setting up storage tank 6, the raw materials sucked up can be collected, reducing the pollution to the construction environment during the material suction stage.

[0044] More specifically, the storage tank 6 is equipped with a discharge valve 7. When the receiving hopper 18 corresponding to the output end of the storage tank 6 is unobstructed, the discharge valve 7 is opened to discharge the filtered raw material to the receiving hopper 18.

[0045] Specifically, the storage tank 6 is equipped with a filter bag, and the output end of the storage tank 6 is connected to the receiving hopper 18.

[0046] The filter bag is used to filter the suction material, ensuring the smooth operation of the suction fan 5. The filtered material is then injected into the receiving hopper 18, reducing the loss of material during cleaning.

[0047] Specifically, a series of suction mechanisms are connected to a storage tank 6, and each suction pipe 2 is equipped with a suction pipe valve 4.

[0048] By connecting a single suction mechanism to only one storage tank 6, the number of devices is reduced, costs are lowered, and equipment flexibility is improved.

[0049] Specifically, one suction mechanism has two sets of suction mechanisms, and one cleaning mechanism has two sets of cleaning mechanisms. By setting the specific number, the equipment can be adapted to conventional pot furnace types.

[0050] The working process of this invention is as follows: The multi-functional cart on the furnace top is moved to the blocked feed hopper, and the suction pipe 2 of the suction mechanism is aligned above the blocked feed inlet 19. The suction lifting frame 3 places the suction pipe 2 into the feed hopper, the suction pipe valve 4 of the suction mechanism is opened, and the suction fan 5 is started to suction material. After suction is completed, the suction lifting frame 3 retracts the suction pipe 2. At this time, the sucked raw material enters the storage tank 6, and is temporarily stored in the storage tank 6 after being filtered by the filter bag.

[0051] After the material suction is completed, close the suction fan 5 and the suction pipe valve 4. Move the multi-functional trolley on the furnace top so that the spiral cleaner 9 of the cleaning mechanism is aligned above the blocked feed inlet 19. Start the lifting motor 12 to lower the lifting platform 13 and the spiral cleaner 9 along the guide rail 14 to the bottom of the cleaning frame 8. Tighten the fixing clamp 17. Open the quick connector 15 between the rotary motor 11 and the spiral cleaner 9. Start the lifting motor 12 to raise the lifting platform 13 along the guide rail 14 to the top of the cleaning frame 8. Install the extension rod 16 between the rotary motor 11 and the spiral cleaner 9. Open the fixing clamp 17. Start the rotary motor 11 and the lifting motor 12 to lower the spiral cleaner 9 to the blocked feed inlet 19. The spiral cutter head will crush the blockage in the feed inlet 19 and continue to lower to clean the inner wall of the channel below the feed inlet 19, completing the cleaning work.

[0052] When the receiving hopper 18 corresponding to the output end of the storage tank 6 is in a smooth state, open the discharge valve 7 to output the filtered raw material to the receiving hopper 18.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions and variations to the above embodiments within the scope of the present invention.
