Process for producing anode paste by direct water spraying and continuous cooling and complete equipment set

Abstract

This invention discloses the productive technology of directed spray, continuous cooling to anode thickeners and the equipment. The method and equipment is following: by continuous mixer, discharging continuously anode thickeners produced into the thickeners cooler, making cooling water flowing from the penstock and into the cooler, which directly spraying water to anode thickeners and making them cool, the anode thickeners after cooling shaping in shaping machine; the smoke gas discharged by the thickeners cooler discharges into air after passing bugdusters, fans and chimneys. The temperature sensor and the flowmeter input gauged data into a computer, and the computer analyses it and emits instruction to adjust the mount of cooling water, which makes the temperature of thickeners dischareged from thickeners cooler to be a set value. Adjusting the dam board of discharging thickeners at the bottom of thickeners cooler, making the mass or weight of anode thickeners in thickeners cooler be stable, making the mass or weight of anode thickeners entering shaping machine be a set value; according negative pressure value measured by the negative pressure sensor, adjusting thickeners cooler to keeping a right negative pressure value.

Description

Technical field: [0001] The invention relates to a prebaked anode production process and equipment, in particular to a continuous cooling production process and equipment for anode paste. technical background: [0002] With the development of modern aluminum industry technology, in the production of electrolytic aluminum in my country, the production scale of prebaked anode electrolytic cells is developing towards large scale, and the production scale of prebaked anode factories matching it is also increasing. The large-scale prebaked anode production line needs the supporting green anode manufacturing process and equipment, and puts forward stricter requirements on the environment, operating costs and production capacity. Therefore, the use of safe, reasonable and effective production methods and equipment can effectively utilize production materials and reduce system failure time, thereby ensuring equipment running time, reducing production and operating costs, and improvi...

AI Technical Summary

Problems solved by technology

Indirect cooling generally adopts a screw conveyor with a jacket, and the cooling medium is passed into the jacket. The cooling medium is water or other media, and the cooling effect is general. The cooling temperature (drop) of the kneading paste is only 10°C at most; the direct air Cooling is generally used for intermittent cooling. The kneading paste is placed on the cooling platform, and the kneading paste is ventilated and blown through the ventilation equipment to cool the kneading paste. The cooling effect is not ideal. The cooling temperature of the kneading paste ( drop) is only 10-20°C at most, and the direct air-cooling equipment occupies a large area, it is difficult to collect the cooling flue gas, and the environment is polluted
