Description

Technical Field

[0001] This utility model belongs to the field of carbon black production technology, and in particular to a reaction device for carbon black production. 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. It requires a reaction device to produce carbon black. When the existing reaction device is in use, the flue gas is adsorbed by the filter screen at the flue outlet. However, when cleaning and collecting the carbon black adsorbed on the surface of the filter screen, the emission of flue gas from the reaction device needs to be stopped, which reduces the production efficiency of the reaction device for carbon black.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN215876635U) describing a reaction device for carbon black production. The device includes a reactor, a feed pipe at one end, a lower exhaust pipe at the top, and an upper exhaust pipe above the lower exhaust pipe. Support frames and receiving frames are installed at both ends of the upper exhaust pipe. A servo motor winds a filter screen with attached carbon black particles onto a receiving roller. During winding, a new filter screen inside the positioning frame is pulled between the upper and lower exhaust pipes. An eccentric block then disengages from a pad, and a spring frame ensures close contact between the upper and lower exhaust pipes. This process is repeated at intervals until all the filter screen inside the positioning frame is detached from the positioning roller. The worker then collects the carbon black adhering to the filter screen surface. However, this device does not consider cleaning the carbon black adsorbed on the filter screen surface, requiring the reactor to stop emitting flue gas, thus reducing the reactor's carbon black production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a reaction apparatus for carbon black production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reaction device for carbon black production, including a carbon black production reactor, an iron exhaust frame for emitting carbon black fumes connected to the top surface of the reactor, two symmetrically arranged fixed frames connected to the side of the exhaust frame, two sets of symmetrically arranged sealed bearings embedded and fixedly connected to the side of the fixed frames, a rotating block with an interference fit on the inner ring of the sealed bearing, a rotating drum connected to the adjacent side of one set of rotating blocks, the rotating drum being divided into an upper part and a lower part, a filter screen for adsorbing carbon black being tumbledly connected to the adjacent side of the upper and lower rotating drums, a movable frame slidably connected to the inner side wall of the two fixed frames, the inner side wall of the movable frame being connected to the filter screen, the two outer side walls of the movable frame being slidably connected to the exhaust frame, and two C-shaped symmetrically arranged pull plates connected to the side of the movable frame.

[0006] Preferably, the inner walls of the two pull plates are arranged concentrically, and the inner wall of the movable frame is flush with the inner wall of the fixed frame.

[0007] Preferably, a filter assembly is provided on the inner wall of the smoke exhaust frame, and the filter assembly includes a sealing frame and a filter frame.

[0008] Preferably, the outer wall of the filter frame is connected to the sealing frame, and the outer wall of the sealing frame is slidably connected to the inner wall of the exhaust frame.

[0009] Preferably, the inner wall of the filter frame is connected to a filter screen for adsorbing carbon black, and the top surface of the filter frame is connected to two L-shaped limiting plates.

[0010] Preferably, the inner sidewalls of the two limiting plates are arranged centrifugally, and the top surface of the limiting plates is connected to an inverted U-shaped fixing plate.

[0011] Preferably, magnetic blocks are embedded and fixedly connected to the inner top wall of the limiting plate, and the bottom surfaces of the two magnetic blocks are magnetically connected to the smoke exhaust rack.

[0012] Preferably, the inner top walls of the two limiting plates abut against the exhaust frame, and a feed inlet is installed on the side of the reactor.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This carbon black production reactor introduces carbon black production raw materials into the reactor through the feed inlet. The flue gas carrying the carbon black is discharged from the reactor through the exhaust frame. The carbon black carried in the flue gas is adsorbed by filter screen 1. When filter screen 1 is disassembled and cleaned, it is often necessary to stop the reactor to produce carbon black and discharge the flue gas, which reduces the reactor's production efficiency for carbon black. By pulling the pull plate, the moving frame moves along the inner wall of the exhaust frame and two fixed frames. As the filter screen 1 and four rotating rollers inside the exhaust frame roll, they are moved out of the exhaust frame, making it easier to clean the carbon black adsorbed by filter screen 1 without stopping the reactor, thus improving the reactor's production efficiency for carbon black.

[0015] In this carbon black production reaction device, after the first filter screen adsorbs the carbon black carried in the flue gas, a small amount of carbon black will still remain mixed in the flue gas. The filter components further adsorb the carbon black mixed in the flue gas to prevent the carbon black from being discharged with the flue gas and wasting resources. By pulling two fixed plates, the magnetic connection between the two magnetic blocks and the exhaust frame is released, allowing the sealing frame to detach from the exhaust frame, thus enabling the disassembly and cleaning of the filter components. The carbon black adsorbed by the second filter screen is cleaned, and the connection between the sealing frame and the exhaust frame is sealed to prevent the flue gas from escaping through the gap between the sealing frame and the exhaust frame, thereby improving the structural stability of the device components.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] To address the issue of reduced carbon black production efficiency due to the need to stop the emission of flue gas from the reaction unit when collecting carbon black adsorbed on the filter screen surface, please refer to [link to relevant documentation]. Figures 1 to 4The structure of the device body includes a carbon black production reactor 1, a feed inlet 17 installed on the side of the reactor 1, an iron exhaust frame 2 for emitting carbon black fumes connected to the top surface of the reactor 1, two symmetrically arranged fixed frames 3 connected to the side of the exhaust frame 2, two sets of symmetrically arranged sealed bearings 4 embedded and fixedly connected to the side of the fixed frame 3, a rotating block 5 with an interference fit on the inner ring of the sealed bearing 4, a rotating drum 6 connected to the adjacent side of one set of rotating blocks 5, the rotating drum 6 being divided into an upper part and a lower part, a filter screen 7 for adsorbing carbon black rolling connected to the adjacent side of the upper and lower rotating drums 6, a movable frame 8 slidably connected to the inner side wall of the two fixed frames 3, the inner side wall of the movable frame 8 being connected to the filter screen 7, the two outer side walls of the movable frame 8 being slidably connected to the exhaust frame 2, and two C-shaped symmetrically arranged pull plates 9 connected to the side of the movable frame 8.

[0027] In this embodiment, carbon black production raw materials are introduced into the reactor 1 through the feed inlet 17. The exhaust frame 2 is welded to the reactor 1 to fix its position. The exhaust frame 2 discharges the flue gas carrying carbon black from the reactor 1 through the exhaust frame 2. The flue gas carrying carbon black is filtered through the filter screen 7, so that the carbon black in the flue gas is adsorbed by the filter screen 7. When disassembling and cleaning the filter screen 7, the reactor needs to be shut down and the exhaust gas needs to be discharged, which reduces the production efficiency of the reactor for carbon black. By pulling the pull plate 9, the moving frame 8 moves between the exhaust frame 2 and the two fixed frames 3. The two upper and two lower rotating rollers 6 roll and contact the filter screen 7, so that the part of the filter screen 7 inside the exhaust frame 2 moves out, which facilitates the cleaning and collection of the carbon black adsorbed by the filter screen 7. There is no need to stop the reactor to clean the carbon black adsorbed by the filter screen 7, which improves the production efficiency of the reactor for carbon black. The length of the filter screen 7 is sufficient to make it easy for part of the filter screen 7 to extend completely into and out of the exhaust frame 2, which improves the structural stability of the device components.

[0028] Specifically, the inner walls of the two pull plates 9 are arranged concentrically, and the inner wall of the movable frame 8 is flush with the inner wall of the fixed frame 3.

[0029] In this embodiment, the end faces of both pull plates 9 are connected to the movable frame 8, which facilitates the movement of the movable frame 8 by pulling the pull plates 9, improving the ease of use of the device and providing space for the movement of the movable frame 8. The two end faces of the rotating roller 6 are in rotational frictional contact with the fixed frame 3 and the movable frame 8, which improves the sealing of the smoke exhaust frame 2, prevents smoke leakage during the movement of the filter screen 7, and improves the structural stability of the device components.

[0030] Specifically, a filter assembly 10 is provided on the inner wall of the smoke exhaust frame 2. The filter assembly 10 includes a sealing frame 11 and a filter frame 12. The outer wall of the filter frame 12 is connected to the sealing frame 11. The outer wall of the sealing frame 11 is slidably connected to the inner wall of the smoke exhaust frame 2. A filter screen 13 for adsorbing carbon black is connected to the inner wall of the filter frame 12.

[0031] In this embodiment, the filter assembly 10 further adsorbs and filters the small amount of carbon black mixed in the flue gas, enhancing the collection effect of carbon black and preventing resource waste. The sealing frame 11 is made of rubber, and the sliding connection between the sealing frame 11 and the exhaust frame 2 is sealed to prevent flue gas from overflowing through the gap between the sealing frame 11 and the exhaust frame 2, thus enhancing the structural stability of the device components. The filter frame 12 provides support for the filter screen 13, enabling the filter screen 13 to further adsorb and collect the carbon black mixed in the flue gas.

[0032] Specifically, the top surface of the filter frame 12 is connected to two L-shaped limiting plates 14. The inner sidewalls of the two limiting plates 14 are arranged centrifugally. The top surface of the limiting plates 14 is connected to an inverted U-shaped fixing plate 15. The inner top wall of the limiting plates 14 is embedded and fixedly connected to a magnetic block 16. The bottom surface of the two magnetic blocks 16 is magnetically connected to the smoke exhaust frame 2. The inner top walls of the two limiting plates 14 abut against the smoke exhaust frame 2.

[0033] In this embodiment, two limiting plates 14 are placed on top of the exhaust frame 2 to fix the depth of the filter frame 12 extending into the exhaust frame 2, providing initial position fixation for the filter frame 12. Two magnetic blocks 16 are magnetically attracted to the exhaust frame 2, further fixing the position of the filter frame 12 during transmission. By pulling the two fixing plates 15, the sealing frame 11 is disengaged from the exhaust frame 2, and the carbon black adsorbed by the filter screen 13 is cleaned and collected.

[0034] Working principle

[0035] In this carbon black production reaction device, the user introduces carbon black production raw materials into the reactor 1 through the feed inlet 17. The flue gas carrying carbon black generated by the reactor 1 is discharged through the exhaust frame 2. The filter screen 7 adsorbs the carbon black in the flue gas. Pulling the pull plate 9 causes the part of the filter screen 7 that adsorbs carbon black to extend out of the exhaust frame 2 to clean and collect the carbon black. The other part of the filter screen 7 extends into the exhaust frame 2 to adsorb the carbon black in the flue gas.

[0036] The movable frame 8 moves along the inner wall of the exhaust frame 2 and the two fixed frames 3. At the same time, the two upper and two lower rotating rollers 6 roll in contact with the filter screen 7, and the two end faces of the rotating rollers 6 rotate and rub against the movable frame 8 and the fixed frames 3 to prevent the smoke in the exhaust frame 2 from overflowing through the movable connection gap of the filter screen 7.

[0037] The filter screen 13 further adsorbs carbon black in the flue gas. Pulling the two fixed plates 15 causes the two limiting plates 14 to move upward, releasing the two limiting plates 14 from the contact between the two magnetic blocks 16 and the exhaust frame 2, allowing the sealing frame 11 to detach from the exhaust frame 2, and cleaning the carbon black adsorbed by the filter screen 13.
