Use method of dry-type purification system for casting flue dust recovery

Abstract

The invention discloses a use method of a dry-type purification system for casting flue dust recovery, and belongs to accessory equipment in the casting field. A large-capacity storage box is utilized; the upper part of the storage box is equipped with a herringbone filter screen to increase filtering area; low-speed flue dust cleaning brushes are mounted in the center of the filter screen; an airinlet pipe is arranged below the herringbone filter screen on a side surface of the storage box; and a high-speed centrifugal fan communicating with the interior of the storage box is arranged at thetop of the storage box for inducing a draught. By adopting the system, a negative pressure air intake is possible, and the filter screen can be cleaned continuously, so that the smooth flue dust recovery and filtering can be maintained. The dry-type purification system for casting flue dust recovery comprises the storage box, a storage box door, a herringbone bracket, the air inlet pipe, an air inlet, the centrifugal fan, a high-speed motor, an air outlet, the filter screen, motor brackets, gear motors, brush strips, a power distribution box and a power supply line.

Description

technical field [0001] The method for using the casting fume recovery dry purification system of the present invention belongs to the auxiliary equipment in the field of foundry, and in particular relates to the recovery and purification of the fume produced by polystyrene during the casting process. Background technique [0002] With the increasing pollution of the atmosphere, environmental protection emissions cannot be relaxed. Most of the model materials used by existing foundry enterprises are polystyrene, and a large amount of smoke and dust will be generated during the casting process. Some enterprises use spray to purify the smoke and dust facilities. The disadvantage is that they pollute the water source. Some enterprises use blowers to send the smoke and dust to the closed filter. Filtering in the net, the disadvantage is that the dust needs to be cleaned regularly, otherwise the dust will block the filter, the air supply pressure of the fan is too high, and the fi...
