A shot blasting cabinet with adjustable impellers includes a cabinet, a plurality of impeller apparatuses, and a plurality of adjusting devices. A shot-blasting working line is defined between an inlet and an outlet of the cabinet. The impeller apparatuses are symmetrically disposed on upper and lower sides of the cabinet. Each impeller apparatus has a protective housing, a driving device, a pair of rotary plates, and a plurality of impeller blades. The driving device connects one of the rotary plates. The protective housing covers the pair of rotary plates and the impeller blades, and defines a shot-blasting exit surface. The shot-blasting exit surface communicates with an interior of the cabinet. The adjusting devices are used to adjust an angle and a distance of the shot-blasting exit surface relative to the shot-blasting working line.

A shot blasting machine includes a shot processing assembly, at least one impeller assembly, a collecting assembly, and a lifting assembly. The at least one impeller assembly includes a pair of rotary plates, a plurality of impeller blades, a plurality of connecting rods, and a protective case body. Each of the rotary plates has a central hole, a plurality of impeller blade grooves, and a plurality of limiting recesses. Each of the plurality of impeller blade grooves has a groove bottom part that is adjacent to the central hole and a groove top part that is adjacent to a circumference of each of the pair of rotary plates. Each of the plurality of impeller blades including a vane part and a pair of blade side parts that are connected to two sides of the vane part, and each of the blade side part has a limiting protrusion.

The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

The centrifugal projector (1) of the present invention has: a side plate (11), a plurality of blades (3) attached to the side plate (11), a control cage (41-45) disposed on a radial inner side of the side plate for releasing the projection material between blades from an opening portion (41a-45e), a distributor (22), disposed on a radial inner side of the control cage, for mixing and supplying the projection material to the control cage, and a rotary shaft (14) for rotating the side plate, blades and distributor; wherein the blades are formed to be pitched so that a radial outer side (3c) thereof is positioned to a rear in the rotational direction (R1) compared to a radial inner side (3b) thereof; the control cage (41-45) has a plurality of opening windows (41a-45e), or a single opening window in which a portion or all of a plurality of opening windows are respectively overlapped and integrated into a single piece.

A system and method for blasting an overhead surface is disclosed herein. The blaster system can comprise a first enclosure, a second enclosure, a pair of recirculators, a pair of loader valves, and a pair of propeller assemblies. The first enclosure can comprise a pair of primary ports, and a pair of control cages. The pair of primary ports can be at the front surface of the first enclosure. The primary ports can receive abrasive material. The pair of control cages can be attached at the bottom surface of the first enclosure forming a pair of curved surfaces, and a plurality of gaps. Each of the curved surface can comprise a slot. Each end of the slot can rest within each of the gaps such that the abrasive material received within the first enclosure can collect within the gaps and falls into the slot.

A wheel assembly for a centrifugal blast wheel machine includes a blast wheel and several blades configured to throw blast media introduced into the blast wheel against a work piece. Each blade includes a first side having a first rail portion that extends along a length of the first side and a second side having a second rail portion that extends along a length of the second side. Each rail portion has a locking member positioned on an outside surface of the rail portion adjacent a first end of the blade. Each rail portion further has a contact surface that is configured to engage a surface of a seat of the blast wheel. Each blade further includes a positioning knob located on the first contact surface to prevent the blade from inadvertently being removed from the seat.

A paint stripping system and method of use is described herein. The paint stripping system can comprise a blaster, a buggy, and a dust collector. The blaster can comprise an upper seal, one or more propeller assemblies, one or more recirculators, and one or more motor assemblies. The upper seal can be at the top surface of the blaster. The upper seal can be positionable under an overhead surface such that waste materials and abrasive material that is produced during operation is collected within the blaster. The propeller assemblies can be mounted within the blaster. The propeller assemblies can propel the abrasive material towards the overhead surface. The recirculators can recycle collected abrasive material. The motor assemblies can actuate the propeller assemblies. The buggy can mount the blaster. The buggy can comprise a scissor lift, and a steering system.

This disclosure provides a new internal weld blasting system for blasting the internal surfaces of pipes, and the method of use thereof. The system comprises a control cage having two relatively narrow openings. An impeller forces abrasives onto a blast wheel, which in turn sprays the abrasives onto the internal surfaces of the pipes.
