Abstract
A wet blast machine for cleaning or preparing surfaces comprises: a treatment source for providing a pressurised mixture of treatment material; a nozzle, the nozzle comprising: an inlet for receiving the pressurised mixture of treatment material; an outlet for ejecting the pressurised mixture; and at least one hole in a wall of the nozzle, the hole for feeding one or more products into the nozzle such that one or more surfaces of the product are exposed to the treatment material whilst within the nozzle, allowing for a more efficient wet blast of the products.
Claims23
A wet blast machine for cleaning or preparing surfaces, said machine comprising:
- a treatment source for providing a pressurised mixture of treatment material;
- a nozzle, said nozzle comprising:
- an inlet for receiving the pressurised mixture of treatment material;
- an outlet for ejecting said pressurised mixture;
- and
- at least one hole in a wall of the nozzle, said hole for feeding one or more products into the nozzle such that one or more surfaces of the product are exposed to the treatment material whilst within the nozzle.
A method of cleaning or preparing surfaces of a product, said method comprising the steps of:
- supplying a flow of pressurised treatment material to an inlet of a nozzle;
- and
- feeding one or more products to be treated through a plurality of holes in a wall of the nozzle, exposing surfaces of the products to the pressurised treatment material whilst within the nozzle.
A blast gun for providing a pressurised mixture of treatment material, the blast gun comprising:
- a treatment pipe comprising a treatment bore, and a nozzle attachment means for attaching a nozzle to the treatment pipe;
- and
- a pressurised air inlet extending from the treatment pipe, the air inlet comprising an air bore, wherein the air bore is in fluid communication with the treatment bore and the nozzle attachment means for injecting pressurised air into the treatment pipe to divert a portion of the treatment material from the treatment pipe into the nozzle.
