Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon black processing technology, and more specifically, to a rotary drum drying device for carbon black processing. Background Technology
[0002] Carbon black is a black powdery substance produced by the incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is elemental carbon, with small amounts of oxygen, hydrogen, and sulfur. During carbon black processing, it needs to be dried to prevent damp carbon black from affecting subsequent use.
[0003] A search revealed that utility model patent CN220119750U discloses a rotary drum drying device, including a feeding box. A first rotating shaft is rotatably connected inside the feeding box. Multiple dispersing rollers are fixedly connected to the outside of the first rotating shaft and inside the feeding box. A sieve plate is fixedly connected inside the feeding box and at the bottom of the first rotating shaft. A collecting hopper is fixedly connected inside the feeding box and below the sieve plate. A second rotating shaft is rotatably connected inside the feeding box and below the collecting hopper. A filter plate is fixedly connected to the outside of the second rotating shaft and inside the feeding box. A third rotating shaft is rotatably connected inside the feeding box and below the filter plate. This patent, through the cooperation of the first rotating shaft, sieve plate, dispersing rollers, first servo motor, and collecting hopper, can disperse clumps of material, thereby accelerating the subsequent drying process. However, the above patent still has the following shortcomings: the dispersing roller and the screen plate on the first rotating shaft rotate synchronously, and the material is easy to accumulate on the screen plate, which makes it difficult to ensure that the material falls smoothly. In addition, when the material after being screened by the filter plate falls to the bottom of the feeding box, it can only be blown into the drying drum by the wind force of the heating fan. When the material accumulates at the bottom of the feeding box, it is not easy to ensure that the material can enter the drying drum smoothly. Therefore, we have proposed a rotary drying device for carbon black processing. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rotary drying device for carbon black processing.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] A rotary drum drying device for carbon black processing includes a base plate, a crushing box fixedly connected to the top surface of the base plate, a drying mechanism located on the top surface of the base plate and on the side of the crushing box, a crushing chamber inside the crushing box, a pusher groove formed on the side of the bottom end of the crushing box, one end of the inner cavity of the pusher groove communicating with the lower end of the inner cavity of the crushing box, a pusher mechanism and a crushing mechanism on the crushing box, multiple support seats fixedly connected to the inner wall of the crushing chamber, springs fixedly connected to the top surface of each of the multiple support seats, screens fixedly connected to the top of the multiple springs, multiple sliding rods fixedly connected to the bottom surface of the screens, the bottom ends of the sliding rods movably sleeved with the support seats, a rotating rod rotatably connected to the inner cavity of the crushing chamber, a protruding plate fixedly sleeved on the outer side of the rotating rod, the top end of the protruding plate contacting the bottom surface of the screen, a first motor fixedly mounted on the front of the crushing box, and the output shaft of the first motor connected to the end of the rotating rod.
[0007] As a preferred embodiment of this utility model, the pushing mechanism includes a hot air blower fixedly sleeved on the side of the crushing box and a second motor fixedly installed on the side of the crushing box. The end of the hot air blower extends into the inner cavity of the pushing groove, and the output shaft of the second motor extends into the inner cavity of the pushing groove and is fixedly connected to a spiral conveying rod. The side of the spiral conveying rod is in contact with the inner wall of the pushing groove, and multiple ventilation holes are provided on the side of the spiral conveying rod.
[0008] As a preferred embodiment of this utility model, the drying mechanism includes two supports fixedly connected to the top surface of the base plate and a third motor fixedly installed on the top surface of the base plate. A drying drum is rotatably connected to the two supports. A second spur gear is fixedly sleeved on the outer side of one end of the drying drum. A first spur gear is fixedly sleeved on the output shaft of the third motor. The first spur gear and the second spur gear mesh with each other. An annular heating plate is fixedly sleeved on the outer side of the drying drum. A discharge ring is fixedly connected to the side of the crushing box and at the end of the inner cavity of the feeding trough. The other end of the drying drum is rotatably connected to the outer side of the discharge ring. Spiral blades are provided on the inner wall of the drying drum.
[0009] As a preferred embodiment of this utility model, the crushing mechanism includes a fourth motor fixedly installed on the top surface of the crushing box. The output shaft of the fourth motor extends into the inner cavity of the crushing chamber and is fixedly connected to a crushing rod. Multiple crushing blades are fixedly connected to the side of the crushing rod.
[0010] As a preferred embodiment of this utility model, a feeding hopper is fixedly sleeved on the top of the crushing box, and the bottom end of the feeding hopper extends into the inner cavity of the crushing chamber.
[0011] As a preferred embodiment of this utility model, a control panel is fixedly installed on the front of the crushing box.
[0012] In a preferred embodiment of this utility model, the side of the screen is fitted to the inner wall of the crushing chamber.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] (1) In this utility model, when the carbon black in the crushing chamber is crushed by the fourth motor, the crushing rod and the crushing knife, the first motor drives the rotating rod and the convex plate to rotate. The upward push of the convex plate on the screen and the downward pull of the spring on the screen cause the screen to move up and down repeatedly, thereby screening the carbon black on the screen. When the top of the convex plate is in contact with the bottom surface of the screen, the bottom surface of the bottom crushing knife is also in contact with the top surface of the screen, ensuring that the carbon black on the top surface of the screen can be completely crushed, thus improving the practicality of the rotary drying device for carbon black processing.
[0015] (2) In this utility model, when the screened carbon black falls into the pusher trough, a hot air blower blows air into the inner cavity of the pusher trough. The hot air from the pusher trough drives the carbon black from the air hole on the screw conveyor into the inner cavity of the drying drum. At the same time, the second motor drives the screw conveyor to rotate, and the screw conveyor pushes the carbon black in the inner cavity of the pusher trough into the inner cavity of the drying drum. This avoids the accumulation of material in the pusher trough and improves the practicality of the carbon black processing rotary drying device. Attached Figure Description

The output shaft of the first motor 12 is connected to the end of the rotating rod 11.
[0027] In this embodiment, the screen 9 is limited by the movable connection between the slide rod 10 and the support base 7, so that the screen 9 can only move up and down.
[0028] For details, please refer to Figure 1 and Figure 3 The feeding mechanism 4 includes a hot air blower 17 fixedly sleeved on the side of the crushing box 2 and a second motor 15 fixedly installed on the side of the crushing box 2.

[0029] In this embodiment, the vent 31 ensures that the hot air blown out by the hot air blower 17 can enter the inner cavity of the drying drum 23 from the inner cavity of the pusher trough 6.
[0030] For details, please refer to Figures 1 to 3 The drying mechanism 3 includes two supports 21 fixedly connected to the top surface of the base plate 1 and a third motor 22 fixedly installed on the top surface of the base plate 1. A drying drum 23 is rotatably connected to the two supports 21. A second spur gear 28 is fixedly sleeved on the outer side of one end of the drying drum 23.

[0031] In this embodiment, the third motor 22 drives the first spur gear 27 to rotate, and the meshing transmission between the first spur gear 27 and the second spur gear 28 drives the drying drum 23 to rotate. The rotation of the drying drum 23 and the cooperation of the spiral blades 25 drive the carbon black to tumble and move. The annular electric heating plate 24 heats the drying drum 23, and the heat from the inner wall of the drying drum 23 dries the carbon black.
[0032] For details, please refer to Figure 2 and Figure 3 The crushing mechanism 14 includes a fourth motor 18 fixedly installed on the top surface of the crushing box 2. The output shaft of the fourth motor 18 extends into the inner cavity of the crushing chamber 5 and is fixedly connected to a crushing rod 19. Multiple crushing blades 20 are fixedly connected to the side of the crushing rod 19.
[0033] In this embodiment, when the top of the convex plate 13 contacts the bottom surface of the screen 9, the convex plate 13 pushes the screen 9 upward. At this time, the top surface of the screen 9 contacts the bottom end of the crushing rod 19, and the bottom surface of the lowest crushing blade 20 also contacts the top surface of the screen 9, ensuring that the carbon black on the top surface of the screen 9 can be completely crushed.
[0034] For details, please refer to Figure 1 and Figure 3 The top of the crushing box 2 is fixedly fitted with a feeding hopper 29, and the bottom end of the feeding hopper 29 extends into the inner cavity of the crushing chamber 5.
[0035] In this embodiment, carbon black is fed into the inner cavity of the crushing chamber 5 from the feeding hopper 29 so that the carbon black in the inner cavity of the crushing chamber 5 can be crushed by the crushing blade 20.
[0036] For details, please refer to Figure 1 A control panel 30 is fixedly installed on the front of the crushing box 2.
[0037] In this embodiment, the control panel 30 is electrically connected to the first motor 12, the third motor 22, the second motor 15, the fourth motor 18, the annular heating plate 24, and the hot air blower 17, respectively. The control panel 30 controls the first motor 12, the third motor 22, the second motor 15, the fourth motor 18, the annular heating plate 24, and the hot air blower 17, and uses an external power source to supply power to the control panel 30, the first motor 12, the third motor 22, the second motor 15, the fourth motor 18, the annular heating plate 24, and the hot air blower 17.
[0038] For details, please refer to Figure 3 The side of the screen 9 is in contact with the inner wall of the crushing chamber 5.
[0039] In this embodiment, the carbon black is ensured to be completely sieved through the screen 9, preventing the carbon black from falling off the side of the screen 9.
[0040] Working principle: In operation, the carbon black to be dried is first fed into the inner cavity of the crushing chamber 5 through the feeding hopper 29. The fourth motor 18 is started to drive the crushing rod 19 and the crushing blade 20 to rotate, and the crushing blade 20 is used to crush the carbon black. At the same time, the first motor 12 is started to drive the rotating rod 11 and the convex plate 13 to rotate. The convex plate 13 pushes the screen 9 to move upward and the spring 8 pulls the screen 9 to return to its original position and move downward, thus causing the screen 9 to move up and down. In this way, the screen 9 screens the carbon black. The screened carbon black falls into the pushing trough 6, and the carbon black that does not fall into the pushing trough continues to be crushed by the crushing blade 20. Then, the hot air blower 17 is started to blow air into the inner cavity of the pushing trough 6. At the same time, the second motor 15 drives the screw conveyor 16 to rotate, and the screw conveyor 16 drives the carbon black to move upward. The carbon black moves into the inner cavity of the drying drum 23. At the same time, the hot air blown by the hot air blown by the hot air blower 17 into the inner cavity of the feeding trough 6 will also drive the carbon black into the inner cavity of the drying drum 23 through the air vent 31. The hot air blown by the hot air blower 17 dries the carbon black in the inner cavity of the drying drum 23. Finally, the annular electric heating plate 24 is energized to generate heat in the drying drum 23, and the third motor 22 is started to drive the first spur gear 27 to rotate. Through the meshing transmission between the first spur gear 27 and the second spur gear 28, the drying drum 23 is driven to rotate. At the same time, the spiral blade 25 drives the carbon black to move forward and turn in the drying drum 23. The heat of the inner wall of the drying drum 23 is used to heat and dry the carbon black. The dried carbon black is discharged from the end of the drying drum 23.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
