Structural features of functional partsThe blast cleaning machine consists mainly of the shot blasting cabinet, abrasive recycling system, dust-removing system ,electric control system and air control system.2.1 Shot blasting cabinetThis cabinet is welded by steel plate and section steel, it's with solid structure, Lined with wear resistant Mn13 shield plate inside to protect the frame from hitting by abrasives or avoiding the abrasives out to hurt any people. The shot blasting cabinet comprises cabinet housing, blast wheel assembly, the door, wind-exhausting openings.The door is opened and closed by the air cylinder.2.2.The main features of the blasting wheelAt the entrance of the blasting cabinet there is plate width detecting device; and on one roller of the blasting cabinet roller conveyer, there is impulse-counting device. The different-width plate presses down different number of pressing rollers, according to the signals of the limit switches on the pressing rollers as well as the impulse counting numbers, the PLC controls the opening quantity (only for small dimension plate) and time of the shot valves, to control the flow of the abrasive and to reduce the vacant projecting time, to meet the purpose of "Blasting when there is plate, and stopping when there is not".This machine adopts large power blast wheels, single wheel abrasive flow rate 125 kg/min, motor power 7.5 kw, projecting speed ≥ 76m/s, life of blade ≥ 1000 hours.Blast wheelThis kind of blast wheel features stout, precisely made and high energy; the wear-resistant parts have long life expectancy, and can be replaced easily. Some structural details:The double-disk is made of tool steel, with good dynamic balancing ability. The blades are inserted into the grooves inside the double-disk.The specially made wear-resistant casting iron blades and protecting plates assure long life.The initial acceleration of the abrasive gained inside the distributor rotating synchronously with the blast wheel guarantees the shockless transfer to the blades.The blades can be replaced easily.2.3 .Abrasive recycling and purifying systemThis system can be divided into the abrasive recycling system and purifying system, they consist of abrasive hopper, abrasive conduit, shot valves, (Blast wheel assemblies), screw conveyors, bucket elevator, abrasive/dust separator, and abrasive distributing screw, etc. The shot valves, screw conveyors, distributing screw, bucket elevator and abrasive/dust separator are interlocked; if the successive element does not work, the preceding element can not be at running status, this avoid the failure caused by the abrasive congestion.Screw conveyorsThe screw conveyor consists of reducer, screw shaft, conveying housing, rolling bearings with bases, etc. It is a kind of standard abrasive/sand horizontal conveying device, is an important part of the abrasive recycling system of the blasting machine.The screw conveyor is a serialized part of our company, with high universality and interchangeability, and stable and reliable performance. The whole screw shaft is machined after welding to guarantee the coaxialness.The screw blades if this part adopt 16Mn material; its inner/outer circle is machined with special workmanship; the blade is then stretched.
