Description

Technical Field

[0001] This utility model belongs to the field of carbon black production technology, and in particular to a drying device for carbon black production. Background Technology

[0002] Carbon black is a black powdery substance produced by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. During the production of carbon black, a drying device is required for drying. Existing drying devices usually use stirring to ensure that the carbon black is heated evenly when drying it, without considering the adjustment of the stirring plate position on the carbon black. This results in uneven heating of the carbon black and reduces the drying effect of the drying device.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN222048389U) for a drying device for carbon black production. The device includes a drying chamber, a vibration assembly fixedly installed inside the chamber, a stirring mechanism movably installed inside the chamber, an exhaust mechanism fixedly installed on the top of the chamber, and a heat recovery mechanism fixedly installed on one side of the chamber. The stirring mechanism includes a drive unit and a stirring unit. This invention can guide and discharge the steam generated during carbon black drying, and filter the steam so that it can be reused as needed through a gas duct. By setting up a heat recovery mechanism, high-temperature steam can be stored in a hot water tank and used for water heating. This effectively utilizes the steam generated after drying for heat preservation or water heating, thereby achieving the effect of waste gas resource reuse. However, this device does not consider adjusting the stirring position of the stirring plate on the carbon black, resulting in uneven heating of the carbon black and reducing the drying effect of the device. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for carbon black production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for carbon black production, comprising:

[0006] A drying oven for carbon black production, with an electric heating plate for drying carbon black connected to the bottom wall of the drying oven;

[0007] A stirring assembly for carbon black mixing includes a mounting plate and a rotating rod. Two symmetrically arranged connecting blocks are rotatably connected to the side of the mounting plate. Connecting plates are connected to the end faces of the connecting blocks, and rotating blocks are connected to the sides of the connecting plates. Two linear motors are mounted on the top of the drying chamber. Moving blocks are connected to the sides of the moving parts of the linear motors. The sides of the moving blocks are rotatably connected to the rotating blocks. The top wall of the drying chamber is rotatably connected to the rotating rod. Several stirring plates for mixing carbon black are connected to the sides of the rotating rod. A rotary motor is connected to the top of the rotating rod via a coupling.

[0008] Preferably, the rotary motor is mounted on the top surface of the mounting plate, and an exhaust assembly is provided on the side of the drying oven.

[0009] Preferably, the exhaust assembly includes a fan and an annular connecting frame, with the input end of the fan connected to the connecting frame.

[0010] Preferably, the side of the connecting rack is connected to the drying oven, and two fixing plates are connected to the inner side wall of the connecting rack.

[0011] Preferably, the two fixed plates are connected to a limiting plate on their adjacent sides, and a connecting rod is rotatably connected to the side of the limiting plate.

[0012] Preferably, the end face of the connecting rod is connected to the rotating shaft of the fan, and the end of the connecting rod away from the fan is connected to a brush plate with several bristles on its surface.

[0013] Preferably, the inner ring surface of the connecting frame is connected to two filter screens, and the adjacent sides of the two filter screens are connected to a limiting plate and two fixing plates, respectively.

[0014] Preferably, the side of the filter screen abuts against the brush of the brush plate, and the top wall and outer wall of the drying chamber are respectively equipped with a feed inlet and a discharge outlet with a solenoid valve.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This drying device for carbon black production includes a feed inlet that introduces carbon black into the drying chamber. A heating plate heats and dries the carbon black inside the chamber, while a stirring assembly agitates the carbon black to ensure uniform heating. A rotary motor provides power, causing its output shaft to rotate, which in turn drives a rotating rod. This causes several stirring plates to rotate around the rotating rod, further agitating the carbon black inside the drying chamber. Simultaneously, two linear motors provide power, moving their moving parts and driving a moving block. A connecting block connects to the connecting plate and the rotating block, providing support to the mounting plate during transmission. This transmission process allows for adjustment of the vertical position of the stirring plates, enhancing the agitation effect on the carbon black and thus improving the drying efficiency of the device.

[0017] The drying device used in carbon black production discharges moisture from the carbon black in the drying chamber through an exhaust assembly. After the carbon black is dried, the carbon black dust is drawn out of the drying chamber by the fan, resulting in carbon black waste. The filter screen provides a shielding effect for the carbon black, but after long-term use, the surface of the filter screen will be clogged with carbon black, reducing the efficiency of moisture discharge. During the rotation of the fan shaft, the connecting rod rotates, thereby enabling the brush plate to rotate around the connecting rod as the axis. This allows the brush of the brush plate to clean the carbon black accumulated on the surface of the filter screen. The limiting plate and two fixing plates provide support and fixation for the rotation position of the connecting rod, improving the structural stability of the device components.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] To address the problem of uneven heating of carbon black caused by the inconvenience of adjusting the stirring position of the stirring plate in the drying equipment used in carbon black production, thus reducing the drying efficiency of the carbon black, please refer to [link to relevant documentation]. Figures 1 to 5 The structure of the device body includes:

[0030] A drying oven 1 for carbon black production has an electric heating plate 23 for drying carbon black connected to the bottom wall of the drying oven 1, and a feed inlet 20 and a discharge outlet 22 with solenoid valves installed on the top wall and outer wall of the drying oven 1, respectively.

[0031] A stirring assembly 2 for stirring carbon black includes a mounting plate 3 and a rotating rod 10. Two symmetrically arranged connecting blocks 5 are rotatably connected to the side of the mounting plate 3. A connecting plate 6 is connected to the end face of the connecting block 5. A rotating block 7 is connected to the side of the connecting plate 6. Two linear motors 9 are installed on the top surface of the drying chamber 1. A moving block 8 is connected to the side of the moving part of the linear motor 9. The side of the moving block 8 is rotatably connected to the rotating block 7. The top wall of the drying chamber 1 is rotatably connected to the rotating rod 10. Several stirring plates 11 for stirring carbon black are connected to the side of the rotating rod 10. A rotary motor 4 is connected to the top surface of the rotating rod 10 through a coupling.

[0032] In this embodiment, carbon black to be dried is introduced into the drying chamber 1 through the feed inlet 20, and the dried carbon black is discharged through the discharge outlet 22. The side of the heating plate 23 is connected to the side wall of the drying chamber 1, so that the top surface of the heating plate 23 replaces the bottom wall of the drying chamber 1 to place the carbon black. The heating plate 23 heats and dries the carbon black inside the drying chamber 1. The stirring assembly 2 stirs the carbon black to ensure uniform heating and enhance the drying effect of the drying device. During the rotation of the output shaft of the rotary motor 4, the rotating rod 10 is driven to rotate, and several stirring plates 11 are rotated around the rotating rod 10 to stir the carbon black. The two sets of connecting blocks 5 distributed on both sides of the mounting plate 3 are symmetrical with the connecting plate 6 and the rotating block 7. Simultaneously, the connecting blocks 5 and rotating blocks 7 on both sides of the connecting plate 6 are staggered, so that the moving parts of the two linear motors 9 move synchronously in opposite directions. The rotating block 7 and the moving block 8 rotate relative to each other, the mounting plate 3 and the connecting block 5 rotate relative to each other, and the connecting plate 6 changes angle. When the moving parts of the two linear motors 9 move to the middle, the two connecting plates 6 are in a vertical state. During the synchronous and continuous reverse movement of the moving parts of the two linear motors 9, the vertical reciprocating movement of several stirring plates 11 is realized in the transmission process. The stirring position of the stirring plates 11 on the carbon black is adjusted to enhance the stirring effect, realize the uniform heating of the carbon black, and improve the drying effect of the drying device on the carbon black. The fixed end of the linear motor 9 is detachably connected to the top surface of the drying box 1 by bolts.

[0033] Specifically, the rotary motor 4 is mounted on the top surface of the mounting plate 3, and the drying chamber 1 is provided with an exhaust assembly 12 on the side. The exhaust assembly 12 includes a fan 13 and an annular connecting frame 14. The input end of the fan 13 is connected to the connecting frame 14, and the side of the connecting frame 14 is connected to the drying chamber 1.

[0034] In this embodiment, the fixed end of the fan 13 is connected to the connecting frame 14 by bolts. The side of the connecting frame 14 is fixedly connected to the drying box 1. The side of the connecting frame 14 away from the fan 13 is flush with the inner side wall of the drying box 1. Power is provided by the fan 13. Under the connecting action of the connecting frame 14, the water vapor inside the drying box 1 is discharged. The fixed end of the rotary motor 4 is connected to the top surface of the mounting plate 3 by bolts.

[0035] Specifically, the inner wall of the connecting frame 14 is connected to two fixing plates 16, and the adjacent sides of the two fixing plates 16 are connected to limit plates 17. The side of the limit plate 17 is embedded with a connecting rod 18, and the end face of the connecting rod 18 is connected to the rotating shaft of the fan 13.

[0036] In this embodiment, the position of the limiting plate 17 is fixed by the connection provided by the two fixing plates 16, thereby fixing the rotation position of the connecting rod 18, so that the connecting rod 18 rotates stably. During the rotation of the fan shaft 13, the connecting rod 18 is driven to rotate, providing power for the rotation of the connecting rod 18.

[0037] Specifically, the end of the connecting rod 18 away from the fan 13 is connected to a brush plate 19 with several bristles on its surface. Two filter screens 15 are connected to the inner ring surface of the connecting frame 14. The adjacent sides of the two filter screens 15 are connected to the limiting plate 17 and the two fixing plates 16, respectively. The side of the filter screen 15 abuts against the bristles of the brush plate 19.

[0038] In this embodiment, the two filter screens 15 provide a shielding and filtering function. After the carbon black is dried, it is very easy to overflow the drying chamber 1, resulting in carbon black waste. After long-term use, the carbon black is very easy to adhere to the surface of the filter screen 15, causing the filter screen 15 to become clogged and reducing the effect of removing moisture from the inside of the drying chamber 1. During the rotation of the fan 13 shaft, the connecting rod 18 is driven to rotate, causing the brush plate 19 to rotate around the connecting rod 18 as the axis. The brush on the surface of the brush plate 19 cleans the carbon black clogged on the surface of the filter screen 15.

[0039] The rotary motor 4, linear motor 9, fan 13, heating plate 23, and solenoid valve are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0040] Working principle

[0041] In this drying device for carbon black production, the user introduces carbon black into the drying chamber 1 through the feed inlet 20, starts the rotary motor 4, and drives the rotary rod 10 to rotate during the rotation of the output shaft of the rotary motor 4. This causes several stirring plates 11 to rotate around the rotary rod 10 as the axis, stirring the carbon black. The two linear motors 9 are started, and the moving parts of the linear motors 9 move synchronously in opposite directions, causing the rotating block 7 and the moving block 8 to rotate relative to each other. The mounting plate 3 and the two connecting blocks 5 rotate relative to each other, and the two connecting plates 6 rotate relative to each other in opposite directions. During the transmission process, the vertical reciprocating movement of several stirring plates 11 is realized, increasing the stirring range.

[0042] When the blower 13 is started, the water vapor inside the drying chamber 1 is discharged under the connecting action provided by the connecting frame 14. After the carbon black inside the drying chamber 1 is dried, it will fly with the airflow, causing the carbon black to clog the filter screen 15. During the rotation of the shaft of the blower 13, the connecting rod 18 is driven to rotate, so that the connecting rod 18 and the limiting plate 17 rotate relative to each other, and the brush plate 19 rotates around the connecting rod 18 as the axis. The brush of the brush plate 19 cleans the carbon black clogging the surface of the filter screen 15.
