Deficient pole shotblast cleaning method and apparatus

Abstract

The present invention discloses a carbon anode scrap ball-blasting method and equipment. Said method includes the following steps: making anode scrap be fed into wheel abrator cabinet, using peening machine to make the anode scrap surface under the process of ball blasting treatment, primary sorting the ball material and waste material, making large granules be fed into waste material system, continuously sorting small granules and dust by means of sorting system of peening machine, using dust-removing system to treat dust, making the ball material be fed into peening machine and can be continuously reused. Said equipment includes the following several portions: fan, filter element dust-removing device, cyclone scrubber, sorting device, rotary vibration sieve, peening machine, wheel abrator cabinet and electric control device, etc.

Description

Technical field: [0001] The invention relates to a device for cleaning the electrolyte on the surface of the anode residue in a carbon plant. Background technique: [0002] Judging from the actual production situation of the carbon plant, the content of sodium, fluorine, aluminum, and iron in the cleaned anode remains is still very high, which is dozens of times or even hundreds of times that of calcined petroleum coke, and eventually leads to some anode products. Trace elements and ash are more than the world's average level, resulting in the internal quality of the anode, especially the anti-air, CO 2 The reactivity is poor, and the carbon plant has always lacked effective means to clean the residual electrode finely. In view of this factor that restricts the further improvement of the anode quality of the carbon plant, it is necessary to develop new technologies and new devices for cleaning the anode electrolyte. [0003] There are many kinds of cleaning technologies an...

Problems solved by technology

In recent years, some carbon factories have carried out a variety of tests and applications for the cleaning of electrode residue electrolytes. One is to use a steel brush to brush the electrode residue as a whole. Due to the irregular shape of the electrode residue, when the steel brush brushes the electrode residue, The cleaning quality of different pole scraps is very different

The second is to use chains to polish and clean the residual poles. This cleaning method has two disadvantages. The first is that the chain cannot be in good contact with the surface of the residual poles, resulting in that the surface of the residual poles cannot be cleaned; the second is that the number of chains is not easy Be sure, if there are too few chains, the contact surface between the surface of the residual pole and the chain will be small, and the residual pole will not be cleaned cleanly. If there are too many chains, the residual pole will be easily broken, so this cleaning method can only be used as a pre-cleaning of the residual pole

The third is to use the vibration method to clean the residual poles. Since part of the electrolyte crust on the residual poles cannot be shaken off by vibration, this method of cleaning the residual poles cannot meet the quality requirements for the residual poles.
