[0026] How this utility works:

[0027] During use, the equipment is moved to one side of the rotary vacuum filter so that the slag suction head 8 is located above the rotary vacuum filter, and the roller brush 10 is driven to rotate by the roller brush motor 9 to make the brush on the roller brush 10 rotate to clean the residual material slag that cannot fall off, and the slag blowing pump 6 rotates to extract the material slag cleaned by the roller brush 10 through the slag suction head 8 and suck it into the slag blowing box 5. After the cleaned material slag is recovered into the slag blowing box 5, clean water and sulfuric acid corrosion inhibitor are added to the mixing barrel 404, and the mixer 403 is driven to rotate by the mixing motor 402 to fully mix the clean water and sulfuric acid corrosion inhibitor in the mixing barrel 404, and the mixed pickling liquid in the mixing barrel 404 is extracted by the mixing pump 405, and the cleaning liquid of the cleaning device 7 is removed. The cleaning nozzle sprays pickling liquid, and pickles the stubborn material residue remaining after the roller brush 10 is cleaned. Clean water is added into the cleaning water tank 1, and the clean water in the cleaning water tank 1 is extracted by the water tank water pump 2. Clean water is sprayed through the cleaning nozzle of the cleaning device 7, and the material residue that falls off after pickling is rinsed into the material bin of the rotary vacuum filter. The clean water is repeatedly rinsed by the water tank water pump 2. After the pickling liquid is sprayed and cleaned by the brush on the roller brush 10 and the cleaning nozzle of the cleaning device 7, the material residue and pickling liquid that fall into the material bin of the rotary vacuum filter are extracted through the recovery head 1204 through the recovery pump 1203 and recovered into the recovery tank 1201. The clean water in the cleaning water tank 1 is extracted by the flushing water pump 13. The washing nozzle 14 washes the material bin and the material slag bin of the rotary vacuum filter and is recycled through the recovery component 12. The material slag and pickling liquid extracted by the recovery pump 1203 enter the recovery box 1201, and the pickling liquid is filtered through the filter screen 1206 in the filter box 1205 and the activated carbon in the filter box 1205, so that the material slag remains on the filter screen 1206. After cleaning, the filter box 1205 is pulled out through the handle of the filter box 1205 to clean the material slag on the filter screen 1206. The workers use the fixing tool 11 to fix the replaced parts of the rotary vacuum filter, and the fixing tool 11 is separated from one side of the slag suction head 8 by rotating the bolt 1101. The fixing tool 11 is fixed by the hoisting equipment. The equipment is fixed by the fixing ring on the fixed tooling 11, and the residual material slag is quickly and thoroughly cleaned, so that the residual material slag does not affect the working speed when it is used next time, thereby avoiding the unclean rinsing of the pickling liquid affecting the use of the rotary drum vacuum filter and reducing the work efficiency. The rotary drum vacuum filter can be quickly cleaned as a whole, avoiding the need for workers to manually clean and increase the physical consumption of the workers, thereby greatly saving the physical strength and working time of the workers, so that the pickling liquid can be filtered to meet the shell discharge standard, avoiding direct discharge to pollute the surrounding environment, so that the parts that need to be replaced of the rotary drum vacuum filter can be quickly lifted, which is convenient for workers to replace parts, greatly speeding up the work speed and saving working time and workers' physical strength.
