The crawler shot blasting machine is a common surface treatment equipment. The following is introduced from its working principle, machine characteristics, technical parameters, application fields and advantages: Working principle The crawler shot blasting machine throws the projectiles to the workpieces in the chamber through a high-speed rotating impeller to achieve the purpose of cleaning. Specifically, after adding a specified number of workpieces to the cleaning chamber, the door is closed, the machine is started, and the workpiece is driven by the roller to start flip. At the same time, the projectiles thrown by the shot blaster at high speed form a fan-shaped bundle, which evenly hits the surface of the workpiece. The thrown projectiles and sand particles flow from the small holes on the track into the screw conveyor at the bottom, and are sent into the hoist through the screw conveyor, and are mentioned to the separator by the hoist for separation. The dust-containing gas is sucked by the fan and sent to the dust collector for filtering, and then becomes clean air and is discharged into the atmosphere. The dust falls into the dust collector box at the bottom of the dust collector by air, and the user can remove it regularly. The waste sand flows out of the waste pipe and can be reused by the user. The pellet sand mixture is recovered from the recycle tube and entered the chamber body. After the separator is separated, the clean projectile is returned to the shot blasting device through the electromagnetic supply gate. Machine features: The shot blasting machine is efficient: The crawler shot blasting machine adopts a cantilever centrifugal shot blasting machine, with large propelling angle, high efficiency, no dead corners, and has the characteristics of long service life and simple structure. Excellent crawler design: wear-resistant rubber crawlers are used to reduce collision and damage to workpieces and reduce machine noise. The separator has good effect: BE-type separator has good separation effect and high productivity, which has a positive effect on improving the life of the blade. Environmental protection of dust collectors: bag-type dust collectors are used, and the dust emission concentration is lower than the national standards, greatly improving the operator's working environment. Technical parameters (taking the Q326 crawler shot blasting machine as an example) The arrangement of the shot blasting device has been simulated by computer three-dimensional dynamics, and the angles and positions of all arrangements are determined by computer design. On the basis of taking care of all workpieces that need to be cleaned, the empty throw of the projectile is minimized, thereby maximizing the utilization rate of the projectile and reducing wear on the cleaning of indoor protective panels. In addition, this model has three types of ejection velocities (75m/s, 80m/s, and 85m/s) corresponding to the lifting volume of the two elevators, and the installation and adjustment methods of the lift motor sprocket are also standardized. Application field Metal workpiece treatment: Not only is it suitable for the cleaning and surface treatment of metal workpieces, but it can also be used to remove welding slag, casting scales and cutting residues. Automobile manufacturing: It can clean the surface of automobile parts, remove welding slag and oil stains, improve coating quality and adhesion. Aerospace: It can be used for surface treatment of aerospace components, remove oxide layers, cut residues and welding slag, and improve the surface quality of components. Railway: It can clean the surface of railway tracks, remove oxide layers and attachments, and enhance the fatigue resistance and service life of the track. Metallurgy: Used for surface treatment of castings in the metallurgy industry, removing scales and sand cores, and improving the quality and strength of castings.
