Background

In the sintering production, a mixer is indispensable equipment in the sintering production technology, and the mixer is mainly used for mixing and granulating, and the working process is as follows: after the material gets into the drum, when the drum is driven rotatory, produce certain centrifugal force, throw the material after the take the altitude, when the gravity of material surpassed centrifugal force, the material then waterfall formula ground drops downwards, because the drum is the slope and arranges, therefore the roll direction of material personally submits certain angle with the gyration, the material just so moves to unloading end along the drum axis direction gradually, so the circulation is repeated, the motion orbit of material just forms the spiral curve, at the same moment that the material got into the drum, water supply system in the compounding machine also begins to work, a large amount of water sprays to the material, the material is moistened, the material is mixed, and produce the spherulite of certain intensity and size, provide the misce-mix for the sintering. However, in the process of one-time operation of the mixer, the sprayed water can generate steam due to higher temperature, and the material enters the cylinder and moves in the cylinder together with the material, so that larger dust can be generated, and the field environment is greatly polluted.

Because dusty gas has high temperature, high wet characteristic, the on-the-spot wet dust collector of chooseing for use removes dust, and this dust remover theory of operation is as follows: the dust-containing gas enters a dust remover channel, is sprayed by a porous spray head to enter a sieve tube, is sprayed out at high speed under the attraction of negative pressure by sieve pores, and collides with bubbles in water at high speed to break in water. The water is boiled under the impact of the air flow, thereby achieving the purpose of fully bathing and purifying the dust-containing gas. But in the in-service use in-process, when other inclined tubes that flow through of dusty, the dust blocks up water dust remover screen pipe easily, and dusty gas can't pass through the high-speed blowout of sieve mesh like this, influences the purifying effect of dust remover, and then causes the unable processing of on-the-spot raise dust.
