Vertical winnowing pulverizer for zirconium fluidizing chlorination industry

Abstract

The invention discloses a vertical winnowing pulverizer for the zirconium fluidizing chlorination industry. The pulverizer is characterized by comprising a pulverizer body, a rack and a PLC, wherein the pulverizer body is installed on the rack, the pulverizer body comprises a top adjusting section and a bottom fixing section, the bottom of the fixing section is connected with an air distributor, aspeed reducer is arranged below the pulverizer body, the speed reducer is electrically connected with a motor, a stirrer stretching into the fixing section is arranged at the top of the speed reducer, a zirconium lining plate is arranged at the inner wall of the fixing section, a zirconium oxide ball is arranged inside the fixing section, a level meter is arranged at one side of the fixing section, and a feeding pipe is arranged at the other side of the fixing section. The pulverizer has the advantages that the equipment structure is simple, the floor area is small, maintenance is easy, investment is small, little vibration is caused, noise is low, a finished product collecting bin can replace a fluidizing chlorination furnace storage drying bin and can be marshaled with a chlorination production line, the production line main control DCS can be connected with the pulverizer, quantitive and continuous pulverizing is performed, and production and management are convenient.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a vertical winnowing pulverizer used in zirconium boiling chlorination industry. Background technique [0002] Now zircon sand plus carbon (petroleum coke), zirconium dioxide plus carbon boiling chlorination, the required raw materials are all using grinding equipment such as Raymond mill, ball mill, rotary mill and high-speed mechanical impact mill, and the product is fine The degree is mostly between 200-1250 mesh, they are all crushed on different equipment, and there are more ultra-fine powders. The particle size control of the material is obtained through calculation or the amplification of small-scale cold bed test data. After the material is broken, there are large differences in shape, bulk specific gravity and particle size. In addition, the particle size control data is unscientific, resulting in a mismatch of particle size. The "stratification" phenomenon is also ...

Problems solved by technology

The particle size control of the material is obtained through calculation or the amplification of small-scale cold bed test data. After the material is broken, there are large differences in shape, bulk specific gravity and particle size. In addition, the particle size control data is unscientific, resulting in a mismatch of particle size. The "stratification" phenomenon is also prone to occur in the boiling chlorination bed. During production, carbon (petroleum coke) is forced to add 10-28% in excess. It will become slag and be discharged to produce solid waste products. At the same time, fine dust powder will be generated during crushing, which will reduce the yield of finished products. When the material is crushed, it will rub and collide with the equipment, the equipment will wear and the material will be polluted, and Fe, Cr, Mn and other harmful impurities
