Sand blasting machine with impurity removal function

Abstract

The invention relates to a sand blasting machine with the impurity removal function. The sand blasting machine comprises a main body and a sand blasting device and further comprises an impurity removal mechanism and a drying mechanism, the impurity removal mechanism comprises a filter screen, a rotating ring, two shaking assemblies, two driving assemblies and a plurality of smashing assemblies, each smashing assembly comprises a nozzle, a fixing pipe and a plurality of sawteeth, and the drying mechanism comprises a rotating assembly, a stirring assembly, a connecting box, an impurity removal net, a power assembly, an air inlet pipe, an air outlet pipe and a plurality of heating rods. The sand blasting machine with the impurity removal function achieves the impurity removal purpose through the impurity removal mechanism, the probability that the sand blasting device is blocked by impurities is reduced, and therefore the sand blasting work cannot be affected, and the reliability of equipment is improved; and by means of the drying mechanism, the drying function is achieved, the situation that the sand blasting device is blocked due to the fact that materials affected with damp cake is prevented, and therefore the influence on normal sand blasting is avoided, and the reliability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a sandblasting machine with an impurity removal function. Background technique [0002] Sandblasting is a process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. The compressed air is used as the power to form a high-speed spray beam to spray the spray material on the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the workpiece surface, the workpiece surface The surface obtains a certain degree of cleanliness and different roughness, which improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, and prolonging the durability of the coating film. It is also conducive t...

Problems solved by technology

[0003] When the existing sandblasting machine is working, if the humidity is too high, it will easily cause agglomeration in the raw material, which will easily affect the normal work of the sandblasting, thereby reducing the reliability of the existing sandblasting machine, not only In this way, when the existing sandblasting machine is sandblasting, if the amount of impurities contained in the raw material is too much, it is easy to block the sandblasting device, increase the probability of damage to the sandblasting device, and affect the normal operation of the sandblasting work, thereby reducing Availability of Existing Sandblasting Machines
