The sponge abrasive is stirred by the stirring unit 113.
The stirring element 110 is connected to an externally disposed control box 200 via a first control line 120.
The first control line 120 is connected to an external intake line 130, and a pressure regulating valve 131 and an intake valve 132 are provided at an inlet of the intake line 130. The first control line 120 is provided with an oil-water separator 121.

Some workpieces are inconvenient to disassemble or move, even workpieces which cannot be subjected to sand blasting in a special sand blasting room can be directly treated by a sponge abrasive sand blasting machine.
With particular reference to fig. 2, a pressure gauge 211 for detecting the pressure in the intake line is provided on the control panel 210 of the control box 200. And a switch 212 or an emergency stop switch 213 for controlling the sponge abrasive blasting machine to be turned on or off, and a touch screen 214 for displaying the control state.
Because of having the above-mentioned structure, the working principle of the invention lies in:
the stirring piece 110 in the abrasive material barrel 100 is controlled by the control box 200 to stir the sponge abrasive materials and then send the sponge abrasive materials out through the sand outlet pipeline 140, and the workpiece surface is subjected to sand blasting through the nozzle 152, so that the workpiece surface meets certain roughness requirements, and the stirring device is equivalent to the equivalent effects of sand blasting such as steel grit, steel shot, corundum sand and the like. And the amount of generated dust is greatly reduced, even the sand can be blasted in the open air, and the investment cost is reduced. The operation is convenient, for example, when the workpiece which is not suitable to move needs sand blasting, the sand blasting machine can move to the vicinity of the equipment to directly sand blast the workpiece. The rebound range of the abrasive is very small, and the abrasive is easy to recover.
The sponge sand is a polyurethane sponge material serving as an adhesive, and abrasive materials of different specifications are bonded together to form a sand mass, so that the sponge sand can be recycled for multiple times.
The porous structure of the polyurethane sponge can effectively reduce splashing and rebounding of the abrasive after sand blasting, and improve the safety of construction.
The wrapping property and the flame retardance of the sponge can also effectively control collision sparks generated in the sand blasting process, and are particularly suitable for the uninterrupted construction requirements of flammable and explosive industries such as ocean engineering, petrochemical engineering and the like.
The sponge sand blasting machine is controlled by an automatic touch screen, sand blasting parameters are clear at a glance, and the phenomena of sand blocking and pulse are avoided to the maximum extent by gas-sand separation. The portable design, the convenience is used in each place is nimble.
Compared with the traditional abrasive, the sponge sanding material used in the invention greatly reduces the sanding dust, is environment-friendly and safer, the sponge is compressed when the sponge sand impacts the surface of the workpiece, the abrasive wrapped in the sponge impacts the surface again, the originally compressed space of the sponge forms a negative pressure area when the sponge rebounds and expands, the dust generated around is adsorbed, the environment is almost dustless, the sponge sand speed after rebounding is reduced, and the sponge sanding material cannot impact and damage surrounding equipment, instruments, meters, ground walls and the like.
The surface treated by the machine can reach the standard of rust removal, sa2.5-Sa3 grade, and the surface roughness can reach 12-100 microns, so that the contact surface of the metal surface is increased, the adhesive force of a coating film is improved, the service life of the coating film is prolonged, the maintenance cost is reduced, and the machine has very remarkable economic benefit.
Compared with international similar products, the sand blasting machine has the characteristics of high rust removal efficiency, low consumption of abrasive materials and energy, safety, reliability, convenience in operation and the like.
When the sponge sand impacts the surface of a workpiece, the sponge is compressed, the abrasive material wrapped in the sponge impacts the surface again, when the sponge is rebounded and expanded, the originally compressed space of the sponge forms a negative pressure area to adsorb dust generated around, so that the environment is almost dustless, the speed of the rebounded sponge sand is reduced, and the sponge sand cannot impact and damage surrounding equipment instruments, ground walls and the like.
The sponge abrasive material combines the adsorption capacity of polyurethane sponge and the cutting capacity of the traditional sand blasting process, becomes flat when impacting the surface of a workpiece under the pushing of compressed air, the abrasive material is instantly exposed to perform sand blasting cleaning on the surface of the workpiece, and when a sand cluster is separated from the surface of the workpiece, the sponge body is rapidly deformed and expanded to form vacuum, and most of dust and impurities generated are adsorbed, so that the environment of sand blasting operation is obviously improved. The sponge abrasive has the characteristics of low dust and environmental protection, and the special porous structure of the sponge sand can adsorb most of fugitive dust and impurities generated in the sand blasting process, so that the visibility of an operation site can be improved, the cleaning efficiency and quality can be improved, and meanwhile, the dust suction amount in the operation process of workers can be greatly reduced.
The foregoing shows and describes the general principles and features of the invention, together with the advantages thereof.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
