Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon black production, and particularly relates to a secondary screening device for carbon black production. Background Art
[0002] Carbon black, also known as black carbon, is an amorphous carbon; it is a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. It can be used as a black dye for manufacturing Chinese ink, printing ink, paint, etc., and is also used as a reinforcing agent for rubber. During the production process of carbon black, a vibrating screen is used to separate impurities and larger carbon black particles from the carbon black to obtain a more uniform carbon black powder; during the production process of carbon black, in order to obtain carbon black particles that meet the requirements, a screening machine is needed to screen the carbon black. However, the surface of carbon black particles often has a certain viscosity. As the screening process continues, the carbon black particles gradually accumulate, resulting in abnormal separation on the screen, causing carbon black of different particle sizes to be mixed together and unable to meet the expected particle size distribution requirements. In view of this, a secondary screening device for carbon black production is proposed. Content of the Utility Model
[0003] To solve the above at least one technical defect, the utility model provides a secondary screening device for carbon black production, including a bottom mounting frame, a side mounting plate is connected above the bottom mounting frame, an inner mounting plate fixed by bolts is connected inside the side mounting plate, and an upper sieve plate capable of shaking off the adhered carbon black particles is connected to the inner mounting plate.
[0004] Further, a shaft cylinder is arranged in the middle of the upper sieve plate, a connecting shaft is inserted into the shaft cylinder, a shaft hole is arranged on the inner wall of the middle part of the inner mounting plate, the connecting shaft is inserted into the shaft hole, and a lower sieve plate capable of performing secondary shaking is further arranged below the upper sieve plate.
[0005] Further, screen plate connecting springs are installed at the four corners of the lower sieve plate, a top cylinder is arranged outside the screen plate connecting springs, and the top of the screen plate connecting springs is connected to the bottom of the upper sieve plate.
[0006] Further, an inclined plane is arranged on the inner bottom surface of the side mounting plate, a material port is arranged on one side of the inclined plane, and a supporting vibration motor is arranged at the bottom of the side mounting plate.
[0007] Further, a supporting mounting frame connecting spring is arranged above the bottom mounting frame, and the top of the mounting frame connecting spring is connected to the bottom of the side mounting plate.
[0008] Beneficial effects: After the carbon black particles screened for the second time fall onto the upper sieve plate on the inner mounting plate, the vibration motor is powered on, and the side mounting plate starts to shake through the mounting frame connecting spring. After the side mounting plate starts to shake, the upper sieve plate rotating on the connecting shaft starts to rotate left and right. Each rotation will hit the limiting plate on the inner wall of the side mounting plate, achieving the effect of initially shaking off the carbon black particles. After the upper sieve plate shakes left and right, it will cause the lower sieve plate to shake through the sieve plate connecting spring. While shaking, the top cylinder will hit the bottom of the upper sieve plate, achieving the effect of secondarily shaking off the carbon black particles and solving the problem of particle adhesion on the sieve mesh.
