The cylinder outer wall shot blasting cleaning machine is a professional equipment that uses high-speed shot blasting technology to clean out the outer wall of the cylinder, rust layer, welding slag and other debris. Its core function is to impact the surface of the workpiece through the high-speed blasting flow thrown by the high-speed blasting device, so that the outer wall of the cylinder can obtain a fine smooth surface, while improving its fatigue strength and corrosion resistance. The following is a detailed analysis of the equipment: 1. Working principle. The shot blasting cleaning mechanism The equipment uses a high-speed rotating shot blasting device (impeller speed can reach 2000-3000r/min) to throw cast steel balls with a diameter of 0.2-3mm high speed along the tangent direction of the blade (speed 50-100m/s), forming a kinetic energy shock wave, and directly peeling off the oxide scale, rust layer and attachments on the outer wall of the steel cylinder. Automatic process loading: The cylinder is automatically positioned to the conveying roller through the loading bracket and the robotic arm. Shot blasting treatment: The cylinder rotates and advances in the shot blasting room to ensure that there are no dead corners at 360°. Cutting: After cleaning, the cylinder is automatically transferred to the finished product area by the cutting mechanism. Projectile circulation: The projectile is vertically lifted by a bucket elevator and filtered by a slag separator, and then re-entered into the shot blasting device to achieve a recycling rate of more than 95%. Dust treatment: The bag dust collector filters dust (dust removal efficiency ≥99%), the emission concentration is less than 20mg/m³, and meets environmental protection standards. 2. The shot blasting chamber of the core component of the equipment structure: high-strength manganese steel protective plate is used to resist the impact of high-speed projectiles and extend the service life. Shot blasting device: 2-8 high-efficiency shot blasting devices are arranged symmetrically, equipped with adjustable angle guide sleeves, suitable for steel cylinders of different specifications. Conveyor system: V-shaped roller or screw rotating disc conveyor to ensure stable rotation and advancement of the cylinder. Pill separator: The air-selected separator realizes efficient separation of projectiles and slags, improving the life of the blade. Dust removal system: The bag-type dust collector is combined with the negative pressure system to control dust emissions and improve the working environment. Auxiliary system PLC electrical control: realizes the automation of the entire process of loading, shot blasting, unloading, projectile circulation, etc. Fault detection: The air valve cylinder controls the unloading system to monitor the pellet flow rate, equipment temperature and other parameters in real time. Safety protection: The enclosed cleaning room is designed with a viewing window and an emergency stop button to ensure safe operation. 3. Technical advantages. Efficient cleaning and cleaning speed can reach 4-15m/min, and the daily processing capacity of a single equipment exceeds 200 cylinders. The surface roughness can reach Ra0.35-0.45μm, and the cleanliness meets the GB 8923 Sa2.0 level standard. Quality improvement eliminates the concentration of surface stress of the cylinder and increases the fatigue resistance by more than 30%. Enhance the adhesion of the paint film and extend the service life of the cylinder by 2-3 times. The recycling rate of environmentally friendly and energy-saving abrasives is ≥95%, reducing material consumption costs. Dust emission concentration is ≤20mg/m³, noise is ≤85dB(A), meeting green production requirements. It is highly adaptable and can handle various types of cylinders with diameters of 100-800mm and lengths of 500-3000mm. By adjusting the angle of the shot blaster and the particle size of the projectile, it can adapt to the cleaning needs of different materials (such as carbon steel, stainless steel)
