Description

Technical Field

[0001] The present invention relates to the kneading technical field of pre-baked anode production, and particularly relates to a dust collection system for use in the production and processing of kneading pots. Background Art

[0002] During the production process of pre-baked anodes, the petroleum coke after qualified high-temperature calcination is transported to the forming process for crushing, screening, and powder grinding. After crushing and screening, the calcined coke of different particle sizes and the calcined coke powder are formed. After accurate metering, the calcined coke of different particle sizes is fed into the upper layer of the kneading pot at a fixed ratio according to the formula, and dry mixing is carried out through stirring and heating for a certain period of time. After the dry material reaches the temperature requirement, the dry material is dropped to the lower layer of the kneading pot, and the binder coal tar pitch is added and kneaded for a certain period of time. After the paste is qualified, it enters the forming production. Because the powder grinding is involved in the batching and the particle size is small (generally ≤ 0.074 mm), affected by the sealing pressure of the kneading pot, dust overflow will occur during the kneading and feeding process, and the feeding process is not smooth. The dust cannot be effectively collected and utilized, which affects the production environment.

The other end of the air outlet pipe 25 is connected to the input end of the shunt 22, and a solenoid valve 26 for controlling the on-off inside it is arranged on the air outlet pipe 25. And a ash hopper 10 is arranged at the bottom of the dust collection box 9. A dust discharge pipe 11 communicating with the inside of the ash hopper 10 is arranged at the bottom of the ash hopper 10. The dust discharge pipe 11 is inserted into the kneading pot 2 and is connected to its inside. A rotating cylinder 12 is rotatably arranged inside the dust discharge pipe 11. A number of ash receiving grooves 121 are arranged in an annular array around the axis on the arc surface of the rotating cylinder 12. And a guide pipe 16 connecting the dust removal area and the inside of the kneading pot 2 is arranged on the dust collection box 9.The exhaust pipe 13 is arranged on the dust collection box 9 and is communicated with the backflush area. A turbine fan 14 is rotatably arranged in the exhaust pipe 13. When the turbine fan 14 rotates, it sucks air from the backflush area side and exhausts it outward. The transmission assembly 15 includes pulley A 151, pulley B 152, toothed belt A 153, pulley C 154 and toothed belt B 155. A transmission shaft A 122 is coaxially arranged on the rotary drum 12. The transmission shaft A 122 is rotatably connected to the ash discharge pipe 11. Pulley A 151 is coaxially connected to the central shaft of the stirring paddle A 61. Pulley B 152 is coaxially connected to the transmission shaft A 122. Pulley A 151 and pulley B 152 are drivingly connected through the toothed belt A 153. A transmission shaft B 141 is coaxially arranged on the turbine of the turbine fan 14. The transmission shaft B 141 is rotatably connected to the exhaust pipe 13.

The transmission assembly 15 drivingly connects the kneading mechanism 6, the rotary drum 12 and the turbine fan 14.

[0026] In this embodiment, raw materials are added into the kneading pot 2 along the feed hopper 7. The motor B65 is started, and the motor B65 drives the stirring paddle A61 to rotate. Then, through the transmission of the gear A611 and the gear B631, the stirring paddle B63 is driven to rotate. While the stirring paddle B63 is rotating, since the gear B631 travels around the internal gear ring 64, the stirring paddle B63 revolves around the stirring paddle A61 while rotating on its own axis, so as to operate within a large range in the kneading pot 2 and knead the raw materials evenly. In this structure, due to the setting of the disc 62, the disc 62 cooperates with the internal gear ring 64 to protect the gear A611 and the gear B631, preventing raw materials from entering the inner side of the internal gear ring 64 and interfering with the gear A611 and the gear B631. The rotation of the stirring paddle A61 drives the pulley A151 to rotate, and then drives the transmission shaft A122 and the transmission shaft B141 to rotate, so that the rotating cylinder 12 rotates at a slower speed while driving the turbo fan 14 to rotate at a high speed. When the turbo fan 14 rotates at a high speed, it sucks air from the dust collection box 9. At this time, the dust raised in the kneading pot 2 enters the dust removal area along the air duct under the suction of the air flow. The dust and air are separated under the action of the dust removal cloth bag 19. The dust falls into the ash hopper 10, and the air is discharged by the turbo fan 14. After falling into the ash hopper 10, it enters the ash discharge pipe 11 along the ash hopper 10, and the dust then enters the ash receiving groove 121. When the ash receiving groove 121 with dust rotates to the opening facing downwards, the dust inside it re-enters the kneading pot 2 under the action of gravity and mixes with the raw materials. In this way, the dust generated in the feeding process of the kneading pot is collected and reused, forming a closed-loop production process, completely solving the problem of poor production environment and at the same time solving the quality fluctuation caused by dust loss. When the dust removal cloth bag 19 needs to be cleaned, the air compressor 23 works and injects air into the air bag 24. Then the solenoid valve 26 is opened, and the compressed air in the air bag 24 enters the diverter 22. The high-pressure gas is evenly dispersed into each branch pipe 20, and then the high-pressure air rushes back into the dust removal cloth bag 19. The dust removal cloth bag 19 is vibrated by the airflow impact to remove dust, and the dust falls into the ash hopper 10 again and flows back into the kneading pot 2.

[0027] Embodiment 2

[0028] As Figure 1 and Figure 2 shown, a dust collection system for use in the production and processing of a kneading pot proposed by the present invention. Compared with Embodiment 1, a discharge hole 201 communicating with the inside is provided at the bottom of the kneading pot 2. A material guiding pipe 3 with only one side open is provided at the bottom of the kneading pot 2.

A screw conveyor 4 is rotatably arranged in the material guiding pipe 3 with a clearance fit therewith, and a motor A5 for driving the screw conveyor 4 to rotate is provided on the material guiding pipe 3.

[0029] In this embodiment, when the kneading mechanism 6 is in the kneading and stirring state, the motor A5 drives the auger 4 to rotate in the reverse direction, so that the bottom layer of raw materials falling into the feed pipe 3 is pushed back into the kneading pot 2 by the reverse pushing of the auger 4 and is transposed with the upper layer of raw materials in the kneading pot 2, improving the mixing efficiency of the raw materials. After kneading is completed, the motor A5 drives the auger 4 to rotate in the forward direction, and then discharges materials through the outlet of the feed pipe 3.
