In the technique scheme, the rotary conveyor of weighing adopts the anti-deviation shirt rim endless-belt that adds, and quantitative control belt weighing instrument also is installed on the rotary conveyor of weighing.
Because in the scheme described in the utility model, the rotary conveyor of weighing is imported and exported by hopper and blanking cover dustproof, and the dedusting interface arranged, weighing section and transportation section adopt labyrinth type dustproof, belt adopts anti-deviation shirt rim endless-belt and acid and alkali-resistance and the high temperature of adding, full suspension scale shelf structure, and built-in swabbing pig and belt deviation detecting device are installed, improved the sealing effectiveness of this equipment and security, reliability and the maintenance convenience of operation of equipment.
In nitrifying process, because of producing steam, for avoiding steam to enter rotary conveyor blanking port, cause caking, thereby produce problem such as putty, at rotary conveyor blanking end and the nitrated helical feed machine inlet capable of weighing, be equipped with and isolate impeller and windrow proofing unit, to block the nitrated steam that is produced, and having judged whether that the putty phenomenon takes place, this isolation impeller passes through sprocket wheel, chain by shaft-mounted step-down gear on the rotary conveyor of weighing, and speedup, synchronized drive can not cause the mishandle of driving.
For solving in the nitrifying process, unslaked lime is nitrated problem fully, promptly at unslaked lime by stirring evenly fully after adding water, and at worm conveyor, spiral reamer adopts the varying pitch structure, like this, improved material and in course of conveying, reached the purpose that stirs while carrying, and by the spiral interface of bleeding, the nitrated steam that produces is taken out, to reduce the gathering of steam, prevent to produce the caking phenomenon of unslaked lime, and stop up normal blanking to nitrated helical feed machine inlet capable.
In sum, the utlity model has the Measuring Precision height, characteristics such as Charge Mixture Control accurately, dustproof dedusting is reliable, and is easy to maintenance improve product quality and production efficiency for the steel works sintering batching provides a cover, and reach the good equipment of environmental requirement.
