Apparatus for purifying asbestos-contaminated soil

An apparatus for purifying asbestos-contaminated soil, comprising:

• a blowing unit including a blowing case which includes a vertical portion in which a plurality of air inlets are formed, and horizontal portions which are connected to one side of the vertical portion in a horizontal direction to form a blower installation space between with the vertical portion, and a plurality of blowers which are installed in the blowing case in multi layers at a predetermined distance in a vertical direction;
• a drop unit including a drop case which has first openings formed on left and right sides thereof, and is configured to fasten one side thereof with an end portion of the horizontal portion of the blowing case, a storage hopper which is installed on an upper portion of the drop case to store a asbestos-contaminated soil therein, a discharge device which is installed under the storage hopper so as to discharge the asbestos-contaminated soil stored in the storage hopper into the drop case by opening and closing the bottom of the storage hopper, shock absorbing plates which is installed in the drop case in multi layers at a predetermined distance in a vertical direction so as to have an orientation inclined in an opposite direction each other, guide plates which are installed on the front of the shock absorbing plates, and is configured to guide air blowing from the blower installed in multi layers in the vertical direction in the blowing unit between shock absorbing plates to form air passages which are separated up and down;
• a transfer unit including a plurality of transfer cases which have second openings formed on left and right sides thereof, and are continuously fastened each other, and screens which are installed between the transfer cases, wherein the transfer unit is fastened to the drop module for passing the air therethrough, while filtering foreign substances contained in the flowing air which was passing through the drop unit;
• and
• a discharge unit which is fastened to the transfer unit, and includes a third opening formed on one side thereof, sloping surfaces so as to gradually narrow in internal space toward the other side thereof, and a vent hole formed on the other end thereof.
