3、 Operating principle and structural characteristics
The structure of the machine is composed of cleaning room, gate, track, hook, hoist
Shot system, separator, shot blasting device, electrical system, etc As follows:
1. Cleaning room
Clean the welding structure of the chamber system, so that the projectiles can be effectively thrown into the
On the surface of the workpiece to be cleaned, one side of the shot blasting machine is installed, and the wall plate is inclined at an angle
Metal protective plates are set on each side of the room opposite to the shot blasting machine, and protective plates are laid at other places,
To protect the chamber wall from being damaged by projectiles.
2. Gate
The two doors open outward to increase the room cleaning capacity. For safety
A limit switch is installed, and the shot blasting machine can only be started after the gate is closed.
3. Hook
The hook is composed of an electric hoist and a deceleration autorotation device
The lowering is completed by the hoist, and the rotation of the hook inside the chamber is completed by the reducer.
4. Hoist
This machine adopts bucket elevator driven by flat belt, and its blanking form is centrifugal
Gravitational dropping: when the projectile bundle is lifted, the dust is sucked away
In case of falling back before entering the shot chute, adjust the bolt to adjust the height of the pulley,
When the machine is blocked due to too much shot or large pieces of material, the bottom of the lower cover can be opened
Clean the cover plate of.
5. Pill supply system
The projectile flow is controlled by the opening clearance of the gate, while the gate is open
The size of opening clearance is adjusted through the gate valve, so that the flow and ejection of projectile Large to equal.
6. Shot separator
This structure is an air separation curtain separator, and the shot sand conveyed by the elevator is mixed
The material flows out through the quantitative gate to form a shot sand curtain with a thickness of about 20mm, which is located in the separation area
Through the horizontal airflow generated by the fan, due to the specific gravity of shot sand and dust
Similarly, after being blown by the air current, the heavy projectiles deviate a small distance, and they fall on the stored projectiles
If the sand is still used in the bucket, the distance between the sand and the crushed small pellet is large, and it falls on
The ash and sand hopper is discharged from the waste pipe, and the dust is discharged through the dust removal pipe.
If the separation effect is different along the separation direction, adjust the air volume valve to
Only when the wind speed passing through the separation zone is within the range of 4~5 m/s, can a good minute be reached Separation effect.
7. Screw conveyor
It is directly driven by the lower pulley of the elevator to drop the cleaning chamber
The shot sand of is conveyed to the bottom of the elevator to prevent objects from entering the auger
And a hoist, and a screen is placed at the bottom of the cleaning room.
Installation, adjustment and operation of the machine
1. Installation of the machine
(1) The volume of this machine is limited by transportation conditions and cannot be assembled and delivered, so it is grouped
It shall be delivered to the user's site for installation, and the user shall reshape it according to his/her own needs and pay attention to
Technical requirements in the drawing.
(2) During the general assembly, fix the cleaning room first, and then connect the shot blasting machine, track and crane
Hook, elevator, screw conveyor, shot separator, shot supply system, electric control system
Assemble according to the general drawing.
(3) The position of the directional sleeve window shall be installed according to the schematic diagram in the general assembly drawing.
2. Adjustment of the machine
After the whole machine is installed (or used for a period of time)
(1) Adjust the directional sleeve in the shot blasting machine, loosen the pressure block of the directional sleeve, and then rotate
Turn the directional sleeve to change the position of the directional sleeve window to change the shot blasting position,
That is, adjust the directional sleeve in the direction of rotation of the shot blasting machine, and move the shooting position forward, otherwise The firing position moves backward.
(2) Adjust the gate valve to meet the required shot supply.
(3) When the belt of the elevator is loose, the adjusting bolt on the upper part of the elevator can be adjusted,
To ensure proper tightness of the belt.
