Background Art
[0002] Precipitated silica is a widely used fine inorganic chemical material, mainly used in rubber, silicone rubber, plastic, coating, ink, pesticide, papermaking, food, medicine, feed and other fields; the production process of precipitated silica includes the preparation of water glass and acid, precipitation reaction, aging, filter pressing, washing, pulping, spray drying, briquetting and packaging. The briquetting process is to press the dried silica powder through a briquetting machine to make the required strips and blocks. The silica powder has many advantages after briquetting, which can not only facilitate subsequent processing and treatment, and improve product quality, but also reduce dust pollution to the environment.
[0003] The briquetting machines in the prior art are generally not equipped with filters, filters and other facilities, and have the following problems: because the powder returning device of the briquetting machine has no filters, filters and other facilities, a large amount of block materials will be mixed in the powder when returning the powder and returned to the briquetting machine, causing the formed block silica to be repeatedly briquetted. The hardness of these repeatedly briquetized blocks of silica is too large, resulting in poor dispersion of the block silica, which reduces the product quality and makes it easy for white spots to appear on rubber when the product is used. Summary of the invention
[0004] The utility model aims to provide a block material and powder material separation device for a briquetting machine in white carbon black production with a simple and compact structure, low manufacturing and maintenance costs and good product quality, so as to solve the problem in the prior art that repeated briquetting of block white carbon black leads to poor dispersion and reduced product quality.
[0005] To achieve the above objectives, the utility model of the briquetting machine block powder separation device in the production of white carbon black comprises a high-level powder bin 1, a blower 2, a briquetting machine 3, a rotary vibrating screen 4, a diaphragm pump 5 and a low-level block bin 6; the outlet of the high-level powder bin 1 is connected to the blower 2, and the blower 2 is connected to the inlet of the briquetting machine 3 through a pipeline; a block outlet is provided on one side of the lower part of the briquetting machine 3 and is connected to the low-level block bin 6 through a pipeline, and a powder return outlet is provided on the conical bottom of the briquetting machine 3; the rotary vibrating screen 4 is cylindrical as a whole, and comprises a screen frame, a screen mesh, a vibrating motor with upper and lower eccentric weights, and a base, and the powder return outlet of the briquetting machine 3 is connected to the rotary vibrating screen 4 through a hose; the screen frame is provided with a block outlet and is connected to the low-level block bin 6 through a pipeline; a receiving tray is provided below the screen mesh, and a powder outlet is provided on one side of the receiving tray and is connected to the inlet of the briquetting machine 3 through a pipeline after being connected to the diaphragm pump 5.
[0006] The screen is high in the middle and low at the periphery, and is provided with different apertures to meet different screening requirements.
[0007] The above-mentioned screen frame is made of metal material and is used to support and fix the screen; the above-mentioned vibration motor with upper and lower eccentric weights serves as a vibration source to make the screen body vibrate to achieve material screening, and the base is used to support the entire rotary vibrating screen to ensure the stability of the equipment.
[0008] The working principle of the above-mentioned rotary vibrating screen 4 is to use the exciting force generated by the upright motor to drive the movement of the upper and lower eccentric weights, so that the screen box can perform horizontal, vertical and inclined three-dimensional motion; in actual use, by adjusting the relative phase of the eccentric weights at the upper and lower ends of the vibration motor, the movement trajectory of the material on the screen surface can be changed, thereby achieving different screening operation purposes; in other words, the vibration motor with upper and lower eccentric weights is used as the excitation source of the rotary vibrating screen, and the exciting force generated by the vibration motor is changed in direction through the eccentric weights, and is converted into three motion modes of horizontal, vertical and inclined. The upper and lower eccentric weights are the key to the operation. They change the direction of the force generated by the vibration motor so that the material can be evenly dispersed on the screen, screened layer by layer and then discharged from the discharge port.
[0009] The utility model of the block material and powder material separation device of the briquetting machine in the production of white carbon black has the following technical characteristics and beneficial effects by setting a rotary vibrating screen as a separation mechanism:
[0010] (1) The device uses the principles of gravity, wind, vibration, etc. to separate lumps and powders. During the production process, lumps and powders enter the rotary vibrating screen separation device. Since the density and particle size of lumps and powders are different, efficient separation of lumps and powders can be achieved in the separation device.
[0011] (2) The overall shape of the vibrating screen is cylindrical, which is conducive to the uniform distribution and flow of materials on the screen surface, thereby improving the screening efficiency and effect.
[0012] (3) The separation device can operate continuously. The separated block white carbon black no longer returns to the briquetting machine, but directly enters the low-level block silo, which improves the briquetting efficiency of the briquetting machine and can significantly improve productivity.
[0013] (4) Effectively separate the block materials and powder materials, greatly reducing dust pollution, improving the packaging working environment and the customer's working environment, and reducing environmental pollution.
[0014] (5) The separation device has a simple structure, is easy to disassemble and clean, and has low manufacturing and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
