QH6910 roller through shot blasting machine, shot blasting machine, Qingdao, Qingdao Steel shot blasting machine manufacturers, Equipment QH6910-through shot blasting machine is mainly used for surface cleaning plates, profiles, and structural parts of the workpiece to remove artifacts surface rust, scale, dirt, weld slag, etc., so that the surface exhibits a metallic color, quality level reached Sa2.5 level, reduce distortion and increase the workpiece paint film adhesion. The machine uses the following key technologies and assurance measures:? Workpiece conveyor system the entire workpiece frequency variable speed conveyor system, both to synchronous operation, each capable of independent action and Industry and blasting chamber equipped with special material abrasion roller jacket prevent projectile throwing fight? blast cleaning uses eight Taiwan and Switzerland + GF + technical shot blasting, shot blasting blade life ≥ 600h is arranged through computer simulation, once throwing projectiles hit and bounce away from the roller secondary projectile uniform coverage consistent. Projectile cleaning? Pellets circulation purification using the most advanced real full curtain overflow induction multistage winnowing splitter? Using a dedicated core polyester hoist belts? Use of remote control projectile controller, and a projectile supplement Each power unit projectile points are located circulatory system failure alarm? blasting pulse cleaning dust removal system uses cartridge-type dust collector, dust emissions to 100mg/m3 (national standard). The whole production line adopts PLC automatic control, photoelectric detection. ? Control into automatic, semi-automatic and manual are three ways to automatically detect various failure points; wearing parts and other features of the cumulative realized when running effectively examine each consumable life, provide the basis for spare parts procurement and replacement . 1.1, the device working principle and technical parameters 1.1.1, the working principle of the workpiece by the roller conveyor shot blasting system to the sealed chamber, the use of high speed rotation of the impeller blasting steel cut wire shot (shot) to accelerate the throw hit the surface , impingement on the surface, scraping a surface to remove rust, mill scale and dirt, showing metal color, conveyor roller sent quickly, so that the workpiece to achieve rust, slag purposes. 1.1.2 The main technical parameters No. Item Specifications 1 processing a workpiece size structure width: ≤ 1000 mm height: ≤ 2000 mm 2 roller maximum load 1.5T / m 3 speed conveyor roller speed: 0.5 ~ 3m/min (stepless governor) Cleanup Speed: 0.5 ~ 1.5 m / min 4 years of treatment capacity (single shift) 5 rust quality grade SISO551300-1967 AB Sa2.5 (Swedish Standard) 6 0.8 to 1.2 using abrasives (steel cut wire shot) 7? steel surface roughness Ra12.5-50? m 8 Noise level <= 90 dB (A) meet the standard 9 GBJ87-85 emissions <100 mg/m3 comply GBJ4-73 content of harmful substances in the work area meets the standard 10 workshop TJ36-79 Standard 11 total air volume 22000 m3 / h 1.1.3.
