Dry quenching primary dust remover

The invention discloses a dry quenching primary dust remover which comprises a dust removal box, one side of the dust removal box is communicated with an input cylinder, one side of the input cylinder is fixedly connected with an air blower, the other side of the dust removal box is communicated with a gas output cylinder, the top of the dust removal box is movably connected with a replacement cover, the top of the replacement cover is provided with a hole, and the interior of the hole is movably connected with a sliding block. The bottom of the sliding block is fixedly connected with a fixing plate B. Through the arrangement of the filter bag and the vibration motor, the filter bag is used for replacing a traditional baffle type to remove particles in gas, large particles can be adsorbed on the filter bag, meanwhile, small particles can also be adsorbed on the filter bag, and therefore the dust removal effect is greatly improved; the vibration motor can be started to drive the filter bag to vibrate, so that
