III.  Structural adjustment and adjustment installation

This machine is a high-performance V-belt conveyor sandblasting cleaning equipment, in the process of cleaning by motor drive worm gear and worm reducer, Towing V-belt conveyor system to the work piece to clean room, and spraying by a all-around of 12 guns, making their oxidation scales and dust’s away quickly, obtaining with certain roughness of the bright surface, at the same time work piece is suffered from strong impact, eliminated the stress of work piece, to avoid deformation. During the cleaning process, falling mixture of dust scattered is collected directly by the set of sand bucket, by the dust removal fan suck in suction separator, after the dust separator was separatedabrasive sand goes to the storage tankdust is driven by fans, through the air duct pipe system, and with filters precipitator dust, efficiency can reach 99%, after purification, the air emissions into the air.


This device has the following several parts: Sandblasting main engine, Belt conveyor system, Segregator, Dust removal system, Electrical Control System.


1. Sandblasting main engine

(1) Structure principle

The master consists of three parts cleaning room, inlet room, and discharge room.

AClean room is installed 12 spray guns, this space structure is passed CAD test and actual verification, can achieve best to clean up the work piece.

BCleaning room is semi-enclosed, equipped with steel and rubber curtain shield to prevent abrasive flying, while room has some negative pressure to prevent the escape of dust.

CCleaning room is equipped with rubber inside body, protect the chamber wall plate from wear and tear, extending the service life; In the cleaning of cone set sand bucket is equipped with the network, to block sundries, protect the nozzle, easy to repair.


(2) Adjust the application and maintenance

ACleaning room protection room and package cast nuts are wearing parts. Must check the degree of wear and change in time, pay attention to install guard plates lap joint, to prevent damage to the wall and endanger safety.

BCleaning room rubber curtain are wearing parts should be replaced if damaged.

CMust cut off the power for maintenance, listing alerts, non-powered operation, and offenders will be could endanger life safety.


2. Belt conveyor system

1Structure principle

The conveying system consists of v belt, master-slave shaft, cycloid reducer and three-phase asynchronous motor, the system is stable and running speed can be controlled by the frequency converter.

2Adjustment and application

According to the work piece cleaning efficiency, adjust the speed of the conveyor system; from low speed to high speed slowly adjust, in order to achieve high quality cleaning efficiency and good economic performance.

3. Separator

1Structure principle

The separator is a cyclone dust mixture was inhaled by back sand tube to the sand separator, by sharing in formation of the cyclone, the walls of the abrasive to jilt to the separator after free fall into the recycling in the store sandbox, dust is inhalation of dust removal system, pure gases into the air after purification treatment, become trapped particles of dust collection.

2Adjustment and application

AThe above screw on regulator separator to change the starting position within the cyclone separator to obtain optimum separation.

BSeparator outlet pipe connection with dust removal system, guarantee the dust into the dust collection box.

4. Dust removal system

1Structure principle

Filter dust collector contains High efficiency filterBack flushing filters bodyCentrifugal fansDust hopperEngine bodyAir hoseair duct elbow.

AThe body by 3 mm high quality low carbon steel plate welded together, both inside and outside surface spray treatment.

Overall Size1200×1200×2000(mm).

BHigh efficiency filterφ320×660total 4 pcs. It is for dust removal process, purification effect accord with national environmental standardsIt is made of 100% polyester fiber material, the thickness of 0.7 mm, 10 um porosity, gas resistance 2.98 mbar (guarantee for 40 cm/s air velocity, the pressure needed to 2.98 mm water column), heat resistance capacity of up to 130 degrees.

CCentrifugal fan type 9-19, A-transmission, power: 7.5 KW, speed:2900R/min

DBack flushing filters body contains the air tank, pulse electromagnetic valve, pipe and other components.

EDust hopper is welded 3mm high quality low carbon steel plate, the surface paint treatment. Overall Size400×400×300(mm).

FAir hose is jointed with PVC pipes.

GCleaning method: vibrating pulse cleaning.

2Adjustment and application

 Vibration pulse cleaning time can be adjusted by pulse controller.
