Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a metal surface sandblasting machine. Background Art

[0002] The sandblasting machine uses compressed air to transport powdered particles (1-4mm in diameter) from one place to another in a pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object to improve the surface quality of the object. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the sandblasting machine makes the surface of the workpiece obtain a certain degree of cleanliness and different degrees of roughness, so that the mechanical properties of the workpiece surface are improved.

[0003] When such sandblasting equipment in the prior art is used, a large amount of dust and debris will be generated when the abrasive impacts the surface of the workpiece. If not processed, the dust will cause unnecessary pollution. Although the sandblasting machine in the prior art is arranged inside a shell, it is still provided with a through hole for the staff to insert their hands. This poses a risk of dust leakage. Therefore, an improved metal surface sandblasting machine is needed to address this problem. Utility Model Content

[0008] Preferably, support feet are fixedly provided at the four corners of the lower end surface of the shell, and the support feet can provide a stable supporting force for the shell.

[0009] Preferably, a collecting bucket is provided at the lower end of the cyclone dust collector through a threaded connection, and the smoke and dust particles generated by the cyclone dust collector can be conveniently collected through the collecting bucket; and the collecting bucket can be removed at any time as needed through a threaded connection to process the smoke and dust particles inside the collecting bucket.

[0010] Preferably, an elastic diaphragm is fixedly provided on one side of the air inlet, and the air inlet can play a guiding single-pass role through the elastic diaphragm; when negative pressure is formed inside the shell, the outside air can push open the elastic diaphragm and enter the shell, and if the pressure inside the shell is normal, the dust inside the shell cannot leak out through the air inlet.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The operating part of the staff of the utility model is sealed by the operating gloves, and no dust leakage will occur. The only air inlet position of the whole device is at the air inlet at the upper end of the shell. When the impeller fan rotates to generate negative pressure inside the cyclone dust removal bin, the smoke and dust air inside the shell can be sucked into the cyclone dust removal bin, and then the outside air can be supplemented into the shell through the air inlet. In this way, the inside of the shell is always in a negative pressure state, and there is no need to worry about dust leakage.

[0013] 2. When the utility model is used, the air inlet can play the role of a single-channel guide through the elastic diaphragm; when negative pressure is formed inside the shell, the outside air can push the elastic diaphragm to enter the shell, and if the shell is at normal pressure, the dust inside the shell cannot leak out through the air inlet, so that dust leakage can be further prevented. When the impeller fan is working when the device is in use, the air that continuously enters the shell through the air inlet can also play the role of cleaning the visual glass window, so that the visual glass window cannot be seen clearly.
