Wet rotary cage sand blasting machine

Abstract

The invention discloses a wet rotary cage sand blasting machine, and relates to the technical field of casting production equipment. The wet rotary cage sand blasting machine comprises a water tank, ahigh-pressure plunger pump, a pressure stabilizer, a pressure regulating valve, a high-pressure water pipe, a descaling nozzle, an air compressor, a pressure stabilizing cylinder, a high-pressure airpipe, a rotating cage motor, a rotating cage, a sand collecting hopper, a sand suction head and a swinging mechanism; the water tank is connected with the high-pressure plunger pump; the high-pressure plunger pump is connected with the descaling nozzle through the high-pressure water pipe; the high-pressure water pipe is provided with the pressure stabilizer and the pressure regulating valve; theair compressor is connected with the descaling nozzle through the high-pressure air pipe; the pressure stabilizing cylinder is arranged on the high-pressure air pipe; the rotating cage motor is in driving connection with the rotating cage; the sand collecting hopper is arranged below the rotating cage; the sand suction head is arranged in the sand collecting hopper; the sand suction head is connected with the descaling nozzle; and the swinging mechanism is in driving connection with the descaling nozzle. According to the wet rotary cage sand blasting machine, dust is not generated during descaling and pollution is avoided; mortar is recycled under negative pressure, and the consumption is low; and the utilization rate of the nozzle is high, the descaling speed is high, and the surface quality of a descaled workpiece is good.

Description

technical field [0001] The invention relates to the technical field of casting production equipment, in particular to a wet-type tumbler sandblasting machine. Background technique [0002] The sandblasting machine is used for cleaning the oxide scale, residual salt, residual oil and other workpiece surfaces after heat treatment of castings; cleaning the oxide scale, molding sand and other workpiece surfaces of black (colored) castings; Cleaning of the surface of workpieces such as molding sand; residues and microburrs of machined parts; cleaning of oxide scales and welding slag of welded parts. [0003] At present, most of the surface cleaning of castings is treated by pickling, dry sandblasting, liquid sandblasting and shot blasting. Pickling is easy to corrode the metal substrate, and it is easy to undergo pickling or hydrogen embrittlement, which affects the metal strength and surface quality. Pollution of the environment; using dry sandblasting or blasting (throwing) sh...

Problems solved by technology

[0003] At present, most of the surface cleaning of castings is treated by pickling, dry sandblasting, liquid sandblasting and shot blasting. Pickling is easy to corrode the metal substrate, and it is easy to undergo pickling or hydrogen embrittlement, which affects the metal strength and surface quality. Pollution of the environment; using dry sandblasting or blasting (throwing) shot treatment, the dust in the process is extremely large, causing environmental pollution, and the oil and salt release agent on the surface of the workpiece is not cleaned cleanly, and dust is attached to the surface; using liquid sandblasting, The sand pump is severely worn, the energy utilization rate is extremely low, and the cleaning speed is slow
