Description

Technical Field

[0001] The present invention relates to the field of calcined coke, and specifically to a calcined coke transfer dust removal device and method. Background Art

[0002] Calcined petroleum coke, as the final product of petroleum refining, is widely used in industries such as graphite electrode production. Its primary product contains oily impurities and needs to be further calcined to meet the standards. Currently, in order to solve many problems in the calcined coke feeding system (such as long conveying distance, serious fugitive emissions and dust in the field, poor environmental hygiene, and harm to the health of laborers); after the calcined coke is cooled, a calcined coke transfer dust removal device is usually used to convey the calcined coke, and the dust raised by the calcined coke during the transfer process is collected and treated; when the existing calcined coke transfer dust removal device is in use, the calcined coke blocks are poured into the feeding section of the conveying trough through the feeding hopper. As the conveying mechanism (such as a belt conveyor, etc.) operates, the calcined coke blocks move along the conveying trough towards the discharging section. During the conveying process, the dust removal air box is started. The dust removal air box forms a negative pressure in the dust removal air cavity through a pipeline connected to the dust removal cover. At this time, the dust generated by the calcined coke blocks during the conveying process, under the action of the negative pressure, is sucked into the dust removal air cavity through the dust removal holes on the dust removal cover, and then enters the dust removal air box to complete the preliminary dust removal operation. At the same time, the blower in the dust raising air box is started, and the air flow generated by the blower is sprayed upward through the dust raising holes on the dust raising plate, raising the fine dust deposited at the bottom of the conveying trough. These raised dusts, together with the dust generated by the calcined coke blocks, are collected by the dust removal cover above; however, in the actual use process, the calcined coke needs to be conveyed on the dust raising plate, and the calcined coke will cover the dust raising plate, and thus also cover the dust raising holes on the dust raising plate. The air flow generated by the blower is sprayed upward through the dust raising holes on the dust raising plate, and is blocked by the calcined coke, and its effect is limited, and it cannot effectively raise all the fine dust deposited at the bottom of the conveying trough. For this reason, we propose a calcined coke transfer dust removal device and method. Summary of the Invention

[0010] Preferably, the auxiliary component includes a circular plate fixedly installed at the bottom end of the power shaft. The circular plate is rotatably connected to a connecting plate, and the connecting plate is rotatably connected to a piston rod. The piston rod slidably penetrates the inside of the guide block and is fixedly connected to a piston. The piston is slidably connected inside the air cylinder.

[0011] Preferably, the conveying pipe, the dust removal box, and the industrial vacuum cleaner are all fixedly installed on the support frame. The blanking dust removal pipe penetrates through the through hole on the support frame and does not contact the support frame. The front plate of the dust removal box is fixedly installed by bolts, and a filter screen is installed at the open end of the dust removal box.

[0012] The present invention also provides a transfer dust removal method for the calcined coke transfer dust removal device, which is characterized by including the following specific steps:

[0013] S1. During use, pour the calcined coke from the feeding hopper into the conveying pipe, and start the reducer to drive the conveying shaft to rotate. The rotation of the conveying shaft will drive the spiral blade to rotate, and use the rotation of the spiral blade to convey the calcined coke in the conveying pipe. Then the calcined coke will pass through the discharge pipe and be discharged from the blanking dust removal pipe.

[0014] S2. During the material conveying process, start the dust suction component and the dust raising component to work. The dust suction component can absorb the dust in the blanking dust removal pipe through the dust holes. The dust raising component will continuously blow air into the blanking dust removal pipe. The air can be blown into the blanking dust removal pipe through the dust holes. Injecting air from the dust holes can prevent the dust holes from being blocked. Secondly, the airflow generated by the dust raising component can blow the dust towards the dust suction hood of the dust suction component to assist the dust suction hood in dust suction. The air discharged by starting the dust suction component will ultimately also be injected into the dust raising pipe of the dust raising component, and the flow direction of the air discharged by the dust suction component is the same as the flow direction of the airflow generated by the dust raising component, increasing the airflow in the dust raising pipe.

[0015] S3. During the material conveying process, the conveying shaft will drive the power component to work. The power component will drive the blanking dust removal pipe to rotate, so that the airflow generated by the dust raising component can be blown into the dust holes at different positions in sequence. And the power component will drive the auxiliary component to work, and the auxiliary component will generate a pulsed airflow when working. The pulsed airflow will be injected into the dust raising pipe of the dust raising component, and the flow direction of the pulsed airflow is the same as the flow direction of the airflow generated by the dust raising component, increasing the airflow in the dust raising pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the present invention is in use, the dust suction component can absorb the dust in the blanking dust removal pipe through the dust holes. The dust raising component continuously blows air into the blanking dust removal pipe. The air can be blown into the blanking dust removal pipe through the dust holes. Injecting air through the dust holes can prevent the dust holes from being blocked. Secondly, the airflow generated by the dust raising component can blow the dust towards the dust suction hood of the dust suction component to assist the dust suction hood in dust suction. And during this process, the blanking dust removal pipe is continuously rotating, so that the airflow generated by the dust raising component can be blown into the dust holes at different positions in turn, thereby ensuring that the dust suction component effectively collects dust.

[0018] 2. The airflow discharged by the dust suction component when absorbing dust will be discharged into the cavity where the two bevel gears are located through the exhaust pipe, which can reduce the temperature around the two bevel gears and alleviate the wear degree of the two bevel gears caused by high temperature during rotation. And this airflow finally enters the dust raising pipe, and the flow direction will be the same as the airflow generated by the pipe blower, increasing the airflow in the dust raising pipe. In addition, the conveying shaft will drive the power component to work, the power component will drive the auxiliary component to work, and the auxiliary component will generate a pulsed airflow when working. The pulsed airflow will be injected into the dust raising pipe of the dust raising component, and the flow direction of the pulsed airflow is the same as the flow direction of the airflow generated by the dust raising component, increasing the airflow in the dust raising pipe. The three airflows form one airflow, making the airflow discharged from the dust raising hood have sufficient intensity and increasing the function of the dust raising component; when the auxiliary component works, it will extract the air around the pipe blower, which will accelerate the heat dissipation outside the pipe blower.

[0019] 3. When the present invention is in use, start the reducer to drive the conveying shaft to rotate. The rotation of the conveying shaft will drive the spiral blade to rotate, and the spiral blade rotation is used to convey the calcined coke in the conveying pipe. In addition, the conveying shaft will drive the power component to work, the power component will drive the blanking dust removal pipe to rotate, so that the airflow generated by the dust raising component can be blown into the dust holes at different positions in turn, and the power component will drive the auxiliary component to work. The auxiliary component will generate a pulsed airflow when working. The pulsed airflow will be injected into the dust raising pipe of the dust raising component, and the flow direction of the pulsed airflow is the same as the flow direction of the airflow generated by the dust raising component, increasing the airflow in the dust raising pipe.

[0029] The conveying assembly 5 includes a conveying shaft 501. The conveying shaft 501 is rotatably connected to two groups of sealed pipe covers 11 and the dust removal box 4 through sealed bearings. A spiral blade 502 is fixedly installed on the outer wall of the conveying shaft 501. The spiral blade 502 is located inside the conveying pipe 1. One end of the conveying shaft 501 is fixedly connected to the driving end of a speed reducer 503 through a coupling. The speed reducer 503 is fixedly installed on a mounting plate 504. The mounting plate 504 is fixedly connected to one group of sealed pipe covers 11. When in use, starting the speed reducer 503 will drive the conveying shaft 504 to rotate. The rotation of the conveying shaft 504 will drive the spiral blade 502 to rotate. The spiral blade 502 rotates inside the conveying pipe 1, and will convey the calcined coke inside the conveying pipe 1.

[0030] The power assembly 10 includes a power shaft 1001. The power shaft 1001 is rotatably connected to a partition inside the dust removal box 4 through multiple groups of sealed bearings. The conveying shaft 501 and the power shaft 1001 are respectively fixedly connected to a group of bevel gears 1002. The two groups of bevel gears 1002 mesh with each other. A small pulley 1004 is fixedly installed on the outer wall of the power shaft 1001. A large pulley 1003 is fixedly installed on the outer wall of the blanking and dust removal pipe 3. A belt 1005 is provided between the small pulley 1004 and the large pulley 1003. The belt 1005 is sleeved in grooves formed on the outer walls of the small pulley 1004 and the large pulley 1003. When in use, the power assembly 10 will drive the auxiliary assembly 9 to work. And when the auxiliary assembly 9 works, it will generate pulsed air flow. The pulsed air flow will be injected into the dust-raising pipe 803 of the dust-raising assembly 8. And the flowing direction of the pulsed air flow is the same as the flowing direction of the air flow generated by the dust-raising assembly 8, increasing the air flow in the dust-raising pipe 803.

[0031] The dust suction assembly 7 includes an industrial vacuum cleaner 701. The dust suction end of the industrial vacuum cleaner 701 is connected to a dust suction pipe 702. The dust suction pipe 702 penetrates through the inside of the dust removal box 4 and is connected to a dust suction hood 703. The exhaust end of the industrial vacuum cleaner 701 is connected to one end of an exhaust pipe 704. The other end of the exhaust pipe 704 is connected to the cavity where the two groups of bevel gears 1002 are located. The diameter of the exhaust pipe 704 gradually becomes smaller from the end close to the industrial vacuum cleaner 701 to the other end. When the industrial vacuum cleaner 701 works, the air discharged by the industrial vacuum cleaner 701 will be discharged from the exhaust pipe 704 into the cavity where the two groups of bevel gears 1002 are located and blown towards the two groups of bevel gears 1002. Since the diameter of the exhaust pipe 704 gradually becomes smaller from the end close to the industrial vacuum cleaner 701 to the other end, when the air flows in the exhaust pipe 704, the temperature of the air will become lower. When the air with reduced temperature blows towards the two groups of bevel gears 1002, it can reduce the temperature around the two groups of bevel gears 1002 and relieve the wear degree of the two groups of bevel gears 1002 caused by high temperature generated during rotation.

[0032] The dust-raising component 8 includes a duct fan 801, which is fixedly installed on a mounting frame 802. The mounting frame 802 is fixedly installed on the inner wall of the dust removal box 4. The air outlet of the duct fan 801 is connected to a dust-raising pipe 803, and the dust-raising pipe 803 is connected to a dust-raising hood 804. An air flow check valve I 805 is assembled at the middle position of the dust-raising pipe 803. During use, when the duct fan 801 is started, the air flow generated by the duct fan 801 will flow through the dust-raising pipe 803 towards the dust-raising hood 804. The air flow check valve I 805 is provided to prevent the air in the dust-raising hood 804 from flowing towards the duct fan 801 through the air flow check valve I 805.

[0033] The dust suction hood 703 and the dust-raising hood 804 are both fixedly installed on the inner wall of the dust removal box 4. The dust suction hood 703, the dust-raising hood 804 and the dust removal box 4 form a dust removal cavity, and multiple groups of the dust holes 6 are located in the dust removal cavity.

[0034] A connecting pipe 12 is installed through the dust removal box 4. One end of the connecting pipe 12 is connected to the cavity where the two bevel gears 1002 are located, and the other end of the connecting pipe 12 is connected to the dust-raising pipe 803. An air flow check valve II 13 is assembled at the position of the connecting pipe 12 close to the dust-raising pipe 803. The diameter of the connecting pipe 12 gradually increases from the end close to the dust-raising pipe 803 to the other end. As the exhaust pipe 704 continuously injects air into the cavity where the two bevel gears 1002 are located, the air in the cavity where the two bevel gears 1002 are located will be discharged into the dust-raising pipe 803 through the connecting pipe 12. Through the air flow check valve II 13, the air flow in the dust-raising pipe 803 is prevented from flowing into the connecting pipe 12. Since the diameter of the connecting pipe 12 gradually increases from the end close to the dust-raising pipe 803 to the other end, the air flow speed discharged from the connecting pipe 12 will gradually increase. The air flow in the connecting pipe 12 enters the dust-raising pipe 803 and has the same flow direction as the air flow generated by the duct fan 801, increasing the air flow in the dust-raising pipe 803.

[0035] The auxiliary component 9 includes a circular plate 901, the circular plate 901 is fixedly installed at the bottom end of the power shaft 1001, the circular plate 901 is rotatably connected to a connecting plate 902, the connecting plate 902 is rotatably connected to a piston rod 903, the piston rod 903 slidably penetrates through the inside of a guide block 904 and is fixedly connected to a piston 905, the piston 905 is slidably connected inside a cylinder 906, an air outlet pipe 907 is connected between the cylinder 906 and a dust-raising pipe 803, a pneumatic exhaust valve 908 is assembled at the middle position of the air outlet pipe 907, an air inlet pipe 909 is connected to the cylinder 906, a pneumatic inlet valve 910 is assembled at the middle position of the air inlet pipe 909, the air inlet of the air inlet pipe 909 is aligned with the outer shell of a pipeline fan 801, a stabilizing rod 911 is fixedly connected to the outside of the air inlet pipe 909, two connecting blocks 912 are fixedly connected to the top end of the cylinder 906, and the stabilizing rod 911 and the two connecting blocks 912 are fixedly connected to the inner wall of a dust removal box 4; during use, the rotation of the power shaft 1001 drives the circular plate 901 to rotate, the rotation of the circular plate 901 and under the action of the connecting plate 902, drives the piston rod 903 to move back and forth, the back-and-forth movement of the piston rod 903 drives the piston 905 to move back and forth inside the cylinder 906. When the piston 905 moves towards the circular plate 901, a negative pressure is formed inside the cylinder 905 at this time, and the pneumatic inlet valve 910 opens, and the air around the pipeline fan 801 enters the cylinder 905 through the air inlet pipe 909, which will accelerate the heat dissipation outside the pipeline fan 801. When the piston 905 gradually moves away from the circular plate 901 along the cylinder 906, the volume of the cylinder 906 decreases, the air is compressed, and the air pressure rises, which will cause the pneumatic exhaust valve 908 to open, and the compressed air is discharged from the cylinder 906 to form a pulsed air flow. Since the piston 905 of the cylinder 906 makes a reciprocating motion inside the cylinder 906, the intake and exhaust processes will alternate continuously, so as to realize continuous intake and exhaust, form a pulsed air flow. The pulsed air flow has a relatively fast flow rate, and the flow direction of the pulsed air flow is the same as the flow direction of the air flow generated by the dust-raising component 8, increasing the air flow inside the dust-raising pipe 803.

[0036] The conveying pipe 1, the dust removal box 4 and the industrial vacuum cleaner are all fixedly installed on a support frame 14, the blanking dust removal pipe 3 penetrates through a through hole on the support frame 14 and does not contact the support frame 14, the dust removal box 4 is fixedly installed with a front plate by bolts, and a filter screen 16 is installed at the open end of the dust removal box 4; the support frame 14 makes the entire device structure stable; the open end of the dust removal box 4 is aligned with the pipeline fan 801 to ensure ventilation when the pipeline fan 801 is working, and the filter screen 16 is provided to prevent dust impurities in the outside air from entering the dust removal box 4, and the filter screen 16 needs to be cleaned regularly.

[0037] The present invention also proposes a transfer dust removal method for a calcined coke transfer dust removal device, which is characterized in that it includes the following specific steps:

[0038] S1. During use, pour the calcined coke into the conveying pipe 1 from the feeding hopper 15, and start the reduction gear 503 to drive the rotation of the conveying shaft 501. The rotation of the conveying shaft 501 will drive the rotation of the spiral blade 502. Utilize the rotation of the spiral blade 502 to convey the calcined coke in the conveying pipe 1. After that, the calcined coke will pass through the discharge pipe 2 and be discharged from the blanking dust removal pipe 3.

[0039] S2. During the material conveying process, start the dust suction assembly 7 and the dust raising assembly 8 to work. The dust suction assembly 7 can absorb the dust in the blanking dust removal pipe 3 through the dust hole 6. The dust raising assembly 8 will continuously blow air into the blanking dust removal pipe 3. The air can be blown into the blanking dust removal pipe 3 through the dust hole 6. Injecting air from the dust hole 6 can prevent the dust hole 6 from being blocked. Secondly, the airflow generated by the dust raising assembly 8 can blow the dust towards the dust suction hood 703 of the dust suction assembly 7 to assist the dust suction hood 703 in dust suction. The air discharged by starting the dust suction assembly 7 will ultimately be injected into the dust raising pipe 803 of the dust raising assembly 8, and the flowing direction of the air discharged by the dust suction assembly 7 is the same as the flowing direction of the airflow generated by the dust raising assembly 8, increasing the airflow in the dust raising pipe 803.

[0040] S3. During the material conveying process, the conveying shaft 501 will drive the power assembly 10 to work. The power assembly 10 will drive the blanking dust removal pipe 3 to rotate, so that the airflow generated by the dust raising assembly 8 can be blown into the dust holes 6 at different positions in sequence. And the power assembly 10 will drive the auxiliary assembly 9 to work, and the auxiliary assembly 9 will generate pulsed airflow when working. The pulsed airflow will be injected into the dust raising pipe 803 of the dust raising assembly 8, and the flowing direction of the pulsed airflow is the same as the flowing direction of the airflow generated by the dust raising assembly 8, increasing the airflow in the dust raising pipe 803.

[0041] The working principle of the present invention: During use, pour the calcined coke into the conveying pipe 1 from the feeding hopper 15, and start the reduction gear 503 to drive the rotation of the conveying shaft 501. The rotation of the conveying shaft 501 will drive the rotation of the spiral blade 502. Utilize the rotation of the spiral blade 502 to convey the calcined coke in the conveying pipe 1. After that, the calcined coke will pass through the discharge pipe 2 and be discharged from the blanking dust removal pipe 3.

[0042] During the material conveying process, start the industrial vacuum cleaner 701. The industrial vacuum cleaner 701 will make the dust suction hood 703 generate suction force through the dust suction pipe 702 and absorb the dust in the blanking dust removal pipe 3 through the dust hole 6. At the same time, start the pipeline fan 801. The airflow generated by the pipeline fan 801 will flow towards the dust raising hood 804 through the dust raising pipe 803. The airflow discharged from the dust raising hood 804 will continuously blow towards the blanking dust removal pipe 3. The air can be blown into the blanking dust removal pipe 3 through the dust hole 6. Injecting air from the dust hole 6 can prevent the dust hole 6 from being blocked. Secondly, the airflow generated by the dust raising assembly 8 can blow the dust towards the dust suction hood 703 of the dust suction assembly 7 to assist the dust suction hood 703 in dust suction.

[0043] When the industrial vacuum cleaner 701 is working, the air discharged by the industrial vacuum cleaner 701 will be discharged from the exhaust pipe 704 into the cavity where the two sets of bevel gears 1002 are located, and blow towards the two sets of bevel gears 1002. Since the diameter of the exhaust pipe 704 gradually decreases from the end close to the industrial vacuum cleaner 701 to the other end, when the air flows in the exhaust pipe 704, the temperature of the air will become lower. When the air with reduced temperature blows towards the two sets of bevel gears 1002, it can reduce the temperature around the two sets of bevel gears 1002 and alleviate the wear degree of the two sets of bevel gears 1002 caused by high temperature during rotation. As the exhaust pipe 704 continuously injects air into the cavity where the two sets of bevel gears 1002 are located, the air in the cavity where the two sets of bevel gears 1002 are located will enter the dust-raising pipe 803 through the connecting pipe 12. Through the one-way air valve two 13, the air flow in the dust-raising pipe 803 cannot rush into the connecting pipe 12. Since the diameter of the connecting pipe 12 gradually increases from the end close to the dust-raising pipe 803 to the other end, the air flow velocity discharged by the connecting pipe 12 will gradually become faster. The air flow in the connecting pipe 12 enters the dust-raising pipe 803, and will have the same flow direction as the air flow generated by the pipeline fan 801, increasing the air flow in the dust-raising pipe 803;

[0044] During the material conveying process, the conveying shaft 501 rotates and drives the power shaft 1001 to rotate under the transmission of the two sets of meshing bevel gears 1002. The rotation of the power shaft 1001 drives the circular plate 901 to rotate, thereby enabling the auxiliary component 9 to start working. When the auxiliary component 9 works, it will generate pulsed air flow. The pulsed air flow will be injected into the dust-raising pipe 803 of the dust-raising component 8, and the flow direction of the pulsed air flow is the same as the flow direction of the air flow generated by the dust-raising component 8, increasing the air flow in the dust-raising pipe 803. Moreover, when the auxiliary component 9 works, it will extract the air around the pipeline fan 801, which will accelerate the heat dissipation outside the pipeline fan 801. Additionally, the rotation of the power shaft 1001 drives the small pulley 1004, and under the transmission of the large pulley 1003 and the belt 1005, it drives the feeding and dust-removing pipe 3 to rotate, so that the air flow discharged from the dust-raising cover 804 can blow into the dust holes 6 at different positions in sequence, ensuring the normal ventilation of all the dust holes 6.

[0045] It should be noted that the speed reducer 503, the industrial vacuum cleaner 701, and the pipeline fan 801 are all existing mature technologies, and their specific working principles will not be described in detail here. It should be noted that when the speed reducer 503, the industrial vacuum cleaner 701, and the pipeline fan 801 are in use, each is externally connected to a suitable power supply with its respective dedicated controller, and the working operation is controlled by its respective dedicated controller.

[0046] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
