Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting devices, in particular to a novel dry and wet dual-purpose sandblasting device. Background Art

[0002] In the patent with authorization announcement number CN208713723U, a new type of sandblasting device is disclosed. By conveying abrasive and compressed air separately, the loss of compressed air by abrasive is avoided, thereby improving the jet force of the airflow and the jet efficiency, thereby improving the grinding efficiency of the abrasive parts, and at the same time avoiding the dust caused by the abrasive being sprayed out of the spray gun.

[0003] The above-mentioned prior art solutions have the following defects: although the above-mentioned patent can avoid the loss of compressed air by abrasives, thereby improving the jet force of the airflow, improving the jet efficiency, and thus improving the grinding efficiency of the abrasive parts, and can also avoid the dust caused by the abrasives being sprayed out of the spray gun, but because the feed bin is directly connected to the sand inlet pipe, the airflow is blocked from entering the sand inlet pipe, so that the sand and air cannot be well mixed, which can easily cause unstable sand feeding. At the same time, because the pipe diameter at the connection between the spray gun and the air inlet pipe is too large, the reaction force of the compressed airflow causes the hands of the gun holder to be too tired, which increases the labor intensity of the staff. For this reason, a new dry and wet dual-purpose sandblasting device is proposed. Utility Model Content
