Description

A kind of novel abrasive blast equipment

Technical field

The utility model relates to abrasive blast equipment technical fields, and in particular to a kind of novel abrasive blast equipment.

Background technique

For product durings manufacture, processing, storage etc., surface is often with oxide skin, iron rust, paint, welding slag, knife mark Deng for the smoothness requirements for allowing the surface quality of workpiece to reach certain, the surface cleaning equipment being most widely used at present is Sand-blasting machine.Sand-blasting machine is one kind using compressed air as power, sand grains high speed is ejected into the surface of processed workpiece, workpiece table Impurity, paint fault, the oxide layer in face etc. are disposed, and a kind of equipment for improving workpiece surface quality effect is reached.

But during polishing using sand-blasting machine workpiece surface, a large amount of dust can be generated.Currently, existing Sand-blasting machine has generally only done one of shield sheet metal structural, causes workpieces processing after sand blasting unit sandblasting is complete, in sandblasting procedures Under the action of air pressure, the dust in sand warehouse is gushed out out of front and back sand warehouse, and depends merely on one layer of metal plate shield and do not seal dust, causes Dust flies out toward the external world, and mean dust concentration is significantly exceeded, and partial region dust concentration reaches dangerous values, seriously affects worker Health.

Utility model content

In order to overcome defect described in the above-mentioned prior art, the utility model provides a kind of novel abrasive blast equipment.

The utility model is that technical solution used by solving the problems, such as it is:

A kind of novel abrasive blast equipment, including rack, rollgang, sand blasting unit, dedusting sand roller device, air blade device, Spiral material pressing device, dust guard and and circulation sand recovering mechanism, in which:
