Abstract
An apparatus and a method of reducing pollution for tire buffing equipment by which a narrow air stream curtain is directed across the cutting width of a rasp immediately ahead of the tread grinding area to contain dust or other small tread materials particles emitted during buffing. Water in the form of a mist is directed between the air curtain and the rasp for mixing with the air to congeal or coagulate the dust and tread material particles into larger size particles which are more efficiently handled by an exhaust or collecting system.
Claims14
A pollution reducing apparatus for a tire buffing machine having a rasp, the apparatus comprising:
- means for supplying a curtain of air directed across a portion of the rasp;
- and
- means for spraying water under pressure between said rasp and said air curtain.
A pollution reducing apparatus for a tire buffing machine having a rasp, the apparatus comprising:
- a casing having an inner air plenum and a slot in flow communication with said air plenum for directing an air curtain across a portion of the rasp;
- air supply means for supplying air under pressure to said air plenum;
- and
- means for directing a spray of water between said rasp and said air curtain.
A pollution reducing apparatus for a tire buffing machine having a rasp, the apparatus comprising:
- a casing having an upper generally flat surface, an inner longitudinally extending air plenum, and an inner water passage;
- an inner plate extending longitudinally along said flat surface;
- a cover plate spaced from said flat surface by said inner plate, said cover plate and said flat surface forming a longitudinally extending slot in flow communication with said air plenum for directing a curtain of air across a portion of the rasp;
- air supply means for supplying air under pressure to said air plenum;
- water supply means for supplying water under pressure to said inner water passage;
- and
- nozzle means in flow communication with said inner water passage for directing a spray of water into the air curtain.
A tire buffing machine comprising:
- an expandable drum means for receiving a tire;
- a frame;
- a rasp rotatably mounted to said frame;
- means for rotating the rasp and for bringing the tire into engagement with the rasp;
- and
- pollution control means mounted to said frame having means for forming and directing an air curtain along a portion of the rasp and having means for directing a water spray into the air curtain.
A method of reducing pollution during tire buffing comprising the steps of:
- placing a tire into position for contacting the blades of a rotating rasp and defining a tread grinding area;
- directing a narrow air stream curtain across the cutting width of the rasp and onto the blades immediately ahead of the tread grinding area;
- and
- directing a water mist between the air curtain and the rasp blades for mixing with the air to congeal or coagulate dust and tread particles created during buffing into larger size particles.
