Double-hook conveyor Shot Blasting Machine is mainly used to remove the rust, welding slag, roll scale and other feculence and obtain and clean metal surface with certain roughness before paint coating of bulldozer, road machine, loading machine and components. When using this machine to do shot blast, there are benefits as follows: improve exterior decoration and inherent quality of the product to bring new commercial opportunities to manufacturers; the workpiece after shot blast could obtain even clean metal surface with certain roughness to promote erosion resistance of mechanical products and metal materials; get rid of welding stress of components and enhance their fatigue strength to obtain permanent use life; strengthen adhesive strength of paint film and improve decoration quality and antisepsis effect of workpiece; the whole machine has realized PLC automatic cleaning model, promoted the efficiency greatly and reduced labor strength of cleaning work.
This machine is designed for the shot-blasting of medium and big size parts which are transported through the blasting tunnel by an overhead conveyor, which can be monorail, double rail or with hoists. Parts can also be supported from the ground by trolleys.
The turbines are mounted on both sides of the shot-blasting section of the tunnel, and their position and orientation are designed according to the type of structures to be treated. This machine can be installed in-line with painting or washing facilities. In case of restricted availability of electric power, the model BASC halve the number of turbines, which are mounted on oscillating supports.
Depending on the height of the machine, the installation may require a pit. The shot-blasting
unit is completed with a self-cleaning dry cartridges dust collector.
1.Shot-blasting Room:
The length of shot-blasting room is 4000mm, and its structural style is as follows:
The body case of shot-blasting room is a kind of welding structure by steel plate and steel sections. There are 16 impeller head around the shot-blasting room whose arrangement is the result of computer dynamic simulation that all arrangement angle and position are designed by computer. Each group of impeller heads keeps a certain angle with the movement direction of work piece which can guarantee to comprehensively clean up the work piece and avoid blasting projectile uselessly as far as possible. Thus enhances the utilization ratio of projectile to the maximum limit and reduces guard plate attrition of shot-blasting room. The room body shell is firm and durable with good rigidity.
The room body interior guard plate uses ZGMn13 with good barrier propterty whose service life is longer than 6000 hours.
2. Front and Back Sealed Chamber:
The front and back sealed chamber's length is 7000mm respectively.The sealed chamber connected with shot-blasting room with one side and the another side is equipt with air-operated folio door. The sealed chamber room body structural style is as follows:
The sealed chamber shell is made in welding structure of steel plate and section, which has enough intensity and rigidity. The front and back sealed chamber are equipped with security access door, which is very convinent to enter the inner rooms for work. The entire sealed chamber body structure is reasonable, firm reliable and with good rigidity.
