Description

Technical Field

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

[0002] Carbon black, also known as carbon black, is an amorphous form of carbon. It is an extremely fine black powder obtained from the incomplete combustion or thermal decomposition of carbon-containing substances such as coal, natural gas, heavy oil, and fuel oil under insufficient air conditions. Carbon black can be used as a black dye in the manufacture of Chinese ink, inks, and paints, and it can also be used as a reinforcing agent for rubber. However, carbon black needs to be granulated using a granulator before further processing and use.

[0003] Existing carbon black granulators use granulation rollers to compress and granulate carbon black during the granulation process, thereby producing carbon black granules. However, some carbon black powder cannot be compressed and granulated during processing, and thus falls into the collection box along with the carbon black granules, resulting in waste of carbon black powder and reduced quality of the finished carbon black granules. Therefore, there is an urgent need for a carbon black granulator to solve this problem. Utility Model Content

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

[0005] To achieve the above objectives, the present invention provides the following technical solution: a granulator for carbon black production, comprising a granulating roller for carbon black granulation and a screening box for carbon black granulation, wherein an installation box is connected to the top surface of the screening box, the granulating roller is rotatably installed inside the installation box, and a feed pipe is connected to the top surface of the installation box, and a collection frame is slidably installed below the side wall of the screening box.

[0006] A square air outlet is provided on one side of the screening box. A barrier net is fixedly installed on the inner wall of the square air outlet. A filter box is fixedly installed on the side wall of the screening box and communicates with the square air outlet. An air intake fan is connected to the side of the screening box away from the filter box. A screening net is fixedly installed on the upper part of the inside of the screening box, and a first vibration motor is fixedly installed on the bottom of the screening net.

[0007] The top surface of the filter box has a strip-shaped hole, and a rectangular frame is slidably installed inside the strip-shaped hole. A filter bag is fixedly installed inside the rectangular frame.

[0008] Preferably, a rectangular rubber pad is fixedly fitted onto the outer wall of the screening mesh, and the outer wall of the rectangular rubber pad is fixedly bonded to the inner wall of the screening box.

[0009] Preferably, a second vibration motor is fixedly installed on the side wall of the barrier net.

[0010] Preferably, a guide plate is horizontally fixedly installed on the inner wall of the screening box, and the guide plate is installed below the air outlet square hole.

[0011] Preferably, a sealing gasket is fixedly installed on the outer wall of the rectangular frame, and the sealing gasket slides and seals against the inner wall of the filter box.

[0012] Preferably, a rubber ring is fixedly fitted on the upper side wall of the rectangular frame. The rubber ring is trapezoidal and slides against the inner wall of the strip hole.

[0013] Preferably, the side wall of the screening box is hinged with a sealing door, and the sealing door is located above the screening screen.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This carbon black granulator, thanks to the design of an air intake fan, an air outlet square hole, a baffle screen, and a filter box, can blow air into the screening box through the air intake fan, blowing the granulated carbon black towards the side wall of the baffle screen. The baffle screen then blocks the carbon black particles, causing the granulated carbon black powder to be blown into the filter box, thereby removing the carbon black powder from the carbon black particles and greatly improving the quality of the finished carbon black particles.

[0016] This carbon black granulator, thanks to the design of the filter box, rectangular frame and filter bag, can effectively filter the carbon black powder entering the filter box through the filter bag, thereby blocking the carbon black powder inside the filter box and expelling the filtered air.

[0017] Compared with existing technologies, this carbon black granulator can effectively filter the residual carbon black powder during the carbon black production process, thereby further improving the quality of the finished carbon black granules. Attached Figure Description

[0024] 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.

[0025] 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.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 3 The main structure of a carbon black granulator shown is a carbon black granulation roller 4 and a carbon black granulation screening box 1. The top surface of the screening box 1 is connected to the mounting box 2. The granulation roller 4 is rotatably installed inside the mounting box 2. The granulation roller 4 is arranged symmetrically, and the driving device of the granulation roller 4 can be, but is not limited to, a motor, gear chain and other driving mechanism.

[0028] Furthermore, the top surface of the installation box 2 is connected to the feed pipe 3, and the side wall of the screening box 1 is connected to the sliding collection frame, which is used to collect the carbon black particles after granulation.

[0029] A square air outlet 6 is provided on one side of the screening box 1. A baffle net 14 is fixedly installed on the inner wall of the square air outlet 6. A filter box 5 is fixedly installed on the side wall of the screening box 1 and communicates with the square air outlet 6. An air intake fan 7 is connected and installed on the side of the screening box 1 away from the filter box 5. When the air intake fan 7 is turned on, air is introduced into the interior of the screening box 1 and the carbon black particles and carbon black powder are blown toward the baffle net 14. Then, the carbon black particles are blocked into the interior of the screening box 1 by the baffle net 14 and the carbon black particles enter the interior of the filter box 5.

[0030] A screen 8 is fixedly installed inside the upper part of the screening box 1, and a first vibration motor 13 is fixedly installed at the bottom of the screen 8. The first vibration motor 13 can perform preliminary filtration on the carbon black particles after granulation, thereby filtering out the larger carbon black particles or those that do not meet the production requirements, thus improving the production quality of carbon black. At the same time, the first vibration motor 13 can accelerate the screening effect of the screen 8.

[0031] The top surface of the filter box 5 has a strip-shaped hole 9. A rectangular frame 10 is slidably installed inside the strip-shaped hole 9. A filter bag 11 is fixedly installed inside the rectangular frame 10. Thanks to the filter bag 11, the carbon black powder entering the filter box 5 is filtered through the filter bag 11 installed inside the filter box 5, and the filtered air is discharged. At the same time, the carbon black powder is collected.

[0032] A rectangular rubber pad 12 is fixedly fitted to the outer wall of the screening screen 8. The outer wall of the rectangular rubber pad 12 is fixedly bonded to the inner wall of the screening box 1. Thanks to the setting of the rectangular rubber pad 12, the outer wall of the screening screen 8 and the inner wall of the screening box 1 are flexibly connected, thereby preventing the vibration of the screening screen 8 driven by the first vibration motor 13 from being transmitted to the screening box 1.

[0033] A second vibration motor 15 is fixedly installed on the side wall of the barrier net 14. The second vibration motor 15 can effectively shake the carbon black particles on the barrier net 14 to fall into the lower part of the screening box 1 and collect them through the collection frame.

[0034] A guide plate 16 is horizontally fixedly installed on the inner wall of the screening box 1. The guide plate 16 is installed below the air outlet square hole 6. The guide plate 16 can guide the carbon black particles falling from the barrier net 14, so that they fall accurately into the inside of the collection frame.

[0035] A sealing gasket is fixedly installed on the outer wall of the rectangular frame 10. The sealing gasket slides and seals against the inner wall of the filter box 5. The sealing gasket can improve the sealing effect between the rectangular frame 10 and the inner wall of the filter box 5, thereby improving the filtration effect of the filter bag 11.

[0036] A rubber ring 17 is fixedly fitted on the upper side wall of the rectangular frame 10. The rubber ring 17 is trapezoidal and slides against the inner wall of the strip hole 9. The rubber ring 17 is squeezed and sealed into the inside of the strip hole 9, which can seal the strip hole 9 and further fix the rectangular frame 10.

[0037] The side wall of the screening box 1 is connected to a hinged sealing door, which is located above the screening screen 8. The sealing door is used to clean up the defective products filtered through the top surface of the screening screen 8.

[0038] Working principle

[0039] In operation, the carbon black granulator first feeds carbon black powder into the housing 2 through the feed pipe 3. Then, the granulating roller 4 inside the housing 2 granulates the carbon black powder and sends the granulated carbon black particles into the screening box 1, where they fall onto the top surface of the screening screen 8. The first vibration motor 13 is then activated to drive the screening screen 8 to perform preliminary screening of the carbon black particles. Subsequently, the air intake fan 7 is activated to introduce air into the screening box 1 and blow the carbon black particles and powder towards the blocking net 14. The blocking net 14 then blocks the carbon black particles into the screening box 1 and allows them to enter the filter box 5. The filter bag 11 installed inside the filter box 5 filters the carbon black powder mixed in with the powder and discharges the filtered air, while simultaneously collecting the carbon black powder.
