Description

Technical Field

[0001] The invention relates to the technical field of pot furnace calcining, in particular to a fluff material processing device. Background Art

[0002] By 2023, domestic calcined coke production will reach nearly 30 million tons, primarily used for the processing of prebaked anodes, cathodes, and negative electrode materials for aluminum, as well as for electrodes and other carbon materials. Over 80% of this production is produced using a retort furnace calcination process. Retort furnaces use delayed petroleum coke, a byproduct of refineries. Different coking processes result in varying delayed petroleum coke quality. In recent years, my country has imported a significant amount of crude oil, resulting in a significant amount of delayed petroleum coke from regions like the Middle East and Indonesia. Delayed petroleum coke from these regions is characterized by a high volatile content, making it prone to coking in the retort during the calcination process. Prolonged coking can cause the retort to bulge in a certain area. If this bulge is not promptly addressed, the upper material stops flowing downward, allowing the lower material to continue discharging. This creates a dead zone within the retort, creating a "burning zone." Pressure gradually builds within this dead zone, ultimately leading to a furnace explosion and serious safety hazards. Therefore, bulging should be addressed promptly to prevent subsequent "burning zones."

[0003] The traditional method of handling bulk material is manual cleaning. Workers use iron rods to insert them into the cleaning holes on both sides of the material tank and the hopper to damage the bulk material surface, so that the material can continue to move down normally. However, manual handling of bulk material has problems such as high-temperature operation, high labor intensity, low efficiency, and poor safety. The existing Chinese utility model patent with publication number CN217636774U discloses a material-poking device for calcining furnace top bulk material, including a driving element, a moving element and a material-poking assembly; the driving element can drive the moving element to move up and down, and the material-poking assembly is connected to the moving element and moves up and down under the drive of the moving element to compact the bulk material. Automated processing of bulk material is achieved. However, the device is arranged between the feeding hopper and the conveyor belt. In order to achieve the compaction effect, pressure is only applied to the surface of the material on the conveyor belt at the top of the furnace. It is a raw material processing solution before the raw materials enter the tank furnace. However, in actual production, material bulging often occurs in the internal space of the tank. The structure and stroke of the device cannot destroy the material surface inside the tank. Continuously applying pressure on the material surface without destroying the internal material surface will further increase the pressure inside the tank, increase the risk of explosion, and pose a safety hazard. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a fluff material processing device, which replaces manual operation with mechanical operation by setting up a matching support mechanism and a lifting mechanism, and the lifting rod entering the interior of the material tank can effectively destroy the fluff material surface inside the material tank, thereby solving the problems of low efficiency and insufficient safety of the existing processing method.

[0005] In order to achieve the above objectives, the main technical solutions adopted by the present invention include: A fluff material processing device includes a supporting mechanism and a lifting mechanism. The supporting mechanism is arranged across the furnace surface of a tank furnace. The lifting mechanism is connected to the supporting mechanism. The lifting mechanism includes a lifting rod. The lifting rod rises and falls in a vertical direction. When raised, it is located above the material tank, and when lowered, it enters the interior of the material tank.

[0006] By setting up a matching supporting mechanism and lifting mechanism, mechanical operation replaces manual operation, reducing the labor intensity of workers and eliminating the need to work in a high-temperature environment. The lifting rod entering the material tank can effectively destroy the fluff surface inside the material tank, making the fluff material processing more efficient and safer.

[0007] Furthermore, it also includes an electric actuator, which is arranged on the top of the support mechanism. The lifting mechanism also includes a screw and a lifting connecting rod beam. The lifting rod is connected to the lifting connecting rod beam, and the lifting connecting rod beam is threadedly connected to the screw. The electric actuator is used to drive the screw to rotate and drive the lifting connecting rod beam to rise and fall.

[0008] By arranging an electric actuator and a specific lifting mechanism, the clockwise or counterclockwise rotation of the electric actuator drives the lifting or lowering of the lifting connecting rod beam, thereby driving the lifting or lowering of the lifting rod.

[0009] Furthermore, there are three lifting rods, which are respectively arranged at the center of the hopper and the center of the two tank cleaning holes, and the tops of the three lifting rods are all connected to the lifting connecting rod beam.

[0010] By setting up three lifting rods, the efficiency of destroying the tarpaulin surface is higher.

[0011] Furthermore, the contact end of the support mechanism and the furnace surface is provided with a wheel, and the furnace surface is provided with a track matching the wheel.

[0012] By setting wheels and furnace surface tracks, the device can be moved on the furnace surface to carry out material processing on the material tanks at various positions.

[0013] Furthermore, the support mechanism includes a lifting rod guide beam, which is slidably connected to the lifting rod and is used to limit the lifting of the lifting rod in the vertical direction.

[0014] The vertical position of the lifting rod is limited by setting the lifting rod guide beam to prevent the lifting rod from being squeezed by the material inside the tank and becoming skewed.

[0015] Furthermore, the support mechanism includes a screw guide beam, and the lifting rod guide beam is slidably connected to the lifting rod and is used to limit the lifting of the lifting rod in the vertical direction.

[0016] The vertical position of the screw is limited by setting the screw guide beam to prevent the screw from shaking.

[0017] Furthermore, the lifting rods are connected by bolts.

[0018] Since the lifting rod works under high temperature conditions and is easily damaged, the maintenance and replacement of the lifting rod is facilitated by adopting bolt connection.

[0019] Furthermore, the length of the lifting rod is 35%-45% of the tank height. At this length, the tank areas corresponding to the first and second layers of the fire channel can be covered, which are also the areas with the most severe coking.

[0020] The beneficial effects of the present invention are: The fluff material processing device of the present invention replaces manual operation with mechanical operation by providing a matching support mechanism and lifting mechanism, thereby reducing the labor intensity of workers and eliminating the need to work in a high-temperature environment. The lifting rod entering the interior of the material tank can effectively destroy the fluff material surface inside the material tank, thereby achieving higher efficiency and better safety in processing fluff materials.

[0023] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 While the accompanying drawings illustrate exemplary embodiments of the present invention, it should be understood that the present invention may be implemented in various forms and should not be limited by the embodiments set forth herein.

[0024] like Figure 1-Figure 2As shown, a fluff material processing device includes a supporting mechanism and a lifting mechanism.

The lifting rod 9 is lifted and lowered in the vertical direction. When raised, it is located above the material tank 2, and when lowered, it enters the interior of the material tank 2.

[0025] By setting up a matching supporting mechanism and lifting mechanism, mechanical operation replaces manual operation, reducing the labor intensity of workers and eliminating the need to work in a high-temperature environment. In addition, the lifting rod 9 entering the interior of the material tank 2 can effectively destroy the fluff surface inside the material tank 2, making the fluff material processing more efficient and safer.

[0026] Specifically, it also includes an electric actuator 6, which is arranged at the top of the support mechanism. The lifting mechanism also includes a screw 7 and a lifting connecting rod beam 8. The lifting rod 9 is connected to the lifting connecting rod beam 8, and the lifting connecting rod beam 8 is threadedly connected to the screw 7. The electric actuator 6 is used to drive the screw 7 to rotate and drive the lifting connecting rod beam 8 to rise and fall.

[0027] By setting up an electric actuator 6 and a specific lifting mechanism, the clockwise or counterclockwise rotation of the electric actuator 6 drives the lifting link beam 8 to be lifted or lowered, thereby driving the lifting rod 9 to be lifted or lowered. The electric actuator 6 is controlled by a motor.

[0028] Specifically, there are three lifting rods 9, which are respectively arranged at the center of the hopper 4 and the center of the cleaning holes of the two material tanks 2, and the tops of the three lifting rods 9 are all connected to the lifting connecting rod beam 8.

[0029] By arranging three lifting rods 9, the efficiency of destroying the awning material surface is higher. The tops of the three lifting rods 9 are all connected to the lifting connecting rod crossbeam 8, realizing synchronous operation.

[0030] Specifically, a wheel 14 is provided at the contact end of the support mechanism and the furnace surface, and a track 11 matching the wheel 14 is provided on the furnace surface.

[0031] By arranging the wheels 14 and the furnace surface rails 11 , the device can be moved on the furnace surface to perform fluffing processing on the material tanks 2 at various positions.

[0032] The retort furnace 1 is composed of multiple identical tanks 2, each with multiple cleaning holes and a hopper 4. A movable mechanism allows the unit to be easily moved to the area of the tank 2 where bulking occurs. Alternatively, a lifting rod 9 can be inserted through different cleaning holes and hoppers 4 in the tank 2. Multiple retort furnaces 1 arranged in a line can be docked onto a track 11, allowing them to operate as a single unit, increasing utilization. When not in use, the unit can be moved to the end of the track 11 to avoid disrupting normal production.

[0033] Specifically, the support mechanism includes a guide beam for the lifting rod 9 , and the guide beam for the lifting rod 9 is slidably connected to the lifting rod 9 and is used to limit the lifting of the lifting rod 9 in the vertical direction.

[0034] The vertical position of the lifting rod 9 is limited by providing a guide beam for the lifting rod 9, thereby preventing the lifting rod 9 from being squeezed by the material 3 inside the material tank 2 and becoming skewed.

[0035] Specifically, the support mechanism includes a screw rod 7 guide beam, and the lifting rod 9 guide beam is slidably connected to the lifting rod 9 to limit the lifting of the lifting rod 9 in the vertical direction.

[0036] The screw rod 7 is vertically limited by providing a guide beam for the screw rod 7 to prevent the screw rod 7 from shaking.

[0037] The guide beams of the lifting rod 9 and the screw rod 7 are limited by guide pieces. The guide beams of the screw rod 7 are limited by two guide pieces connected by bolts. The guide beams of the lifting rod 9 are limited by six guide pieces connected by bolts respectively.

[0038] Specifically, the lifting rod 9 is connected by bolts.

[0039] Since the lifting rod 9 works under high temperature conditions and is easily damaged, the maintenance and replacement of the lifting rod 9 are facilitated by adopting bolt connection.

[0040] Specifically, the length of the lifting rod 9 is 35%-45% of the height of the tank 2. Preferably, it is 35%-40%. At this length, the area of the tank 2 corresponding to the first and second layers of the fire channel can be covered, which is also the area with the most serious coking.

[0041] By limiting the length of the lifting rod 9 , it is ensured that the lifting rod 9 can handle the fluff generated at various positions inside the material tank 2 .

[0042] Specifically, the support mechanism also includes a frame 10, a middle support beam 15, and a bottom support beam 16. The frame 10 is arranged across the furnace surface of the retort furnace 1, the middle support beam 15 is arranged in the middle of the frame 10, the bottom support beam 16 is arranged at the bottom of the frame 10, and the guide beams for the lifting rod 9 and the screw 7 are arranged at the bottom of the frame 10. The frame 10 and beams in the support mechanism are made of steel structure, and the middle support beam 15 and the bottom support beam 16 provide reinforcement support for the frame 10.
