Continuous automatic sandblasting machine
Continuous automatic sandblasting machine



Host shell 
It is welded with 3mm thick steel plate and painted on the surface. The key parts are provided with a shield and rubber skin to prevent dust from escaping. The lower part of the cabin has a filter screen to prevent large debris and workpiece from falling into the sand. The observation machine on the main part of the blasting machine can observe the whole process and handle the unexpected situation at any time.
Spray mainframe dimensions: 2400mm (length) * 2400mm (width) * 2200mm (height) (excluding separator height);
Dust box dimensions: 1250mm (length) * 1200mm (width) * 2400mm (height) (excluding fan height)
Large turntable size: Ø2200mm is placed on 50 small sandblasting stations;
Sandblasting gun: 2 groups of 12 (the rocking speed can be frequency-controlled, the angle can be adjusted by 360°);
Total equipment power: about 10kw.
Dust removal system
This machine is equipped with a 9-cartridge dust box to prepare a special dust-removing filter for PHOENIX brand of Sino-Japanese joint venture. The filtration efficiency is: 99% larger than 10 micron particles. It can effectively separate the dust from the gas, remove the dust generated during the work, and greatly reduce the damage caused by environmental pollution. Its exhaust gas emission can reach the national environmental protection emission standard (GB-/T16157-1996): TSP≤120mg/m3.
The filter dust collector is composed of a high-efficiency filter element, a backflushing filter mechanism, a centrifugal fan, a dust collecting bucket, a body, a duct, and a duct elbow.

1) The body is welded by 2.0mm high-quality low-carbon steel plate, and the inner and outer surfaces are painted. Dimensions: 1200 × 1200 × 2400 (mm).
2) High-efficiency filter element φ320×600, a total of 9 pieces. The high-efficiency filter element is used for dust removal treatment, and the purification effect is in line with national environmental protection standards. The high-efficiency filter element is made of 100% polyester fiber material with a thickness of 0.7mm, a gas permeability of 10um, a gas resistance of 2.98mbar (the required pressure is 2.98mm water column when the air flow rate is 40cm/s), and the temperature resistance is up to 130 degrees. .
3), centrifugal fan 4-72 type, A-type transmission, power: 7.5KW, speed: 2900 rev / min.
4) The back-blowing filter mechanism is composed of a gas storage tank, a pulse solenoid valve, a gas pipe and the like.
5) The dust collecting truck is welded by 4mm high-quality low-carbon steel plate and painted on the surface. Dimensions: 400 × 400 × 300 (mm).
6) The air duct is made of PVC pipe and the surface is painted. An air volume adjusting plate is arranged at the elbow of the air duct to adjust the amount of air intake.
7), cleaning method: pulse vibration cleaning.
Air compression system (customer-owned):
The blasting pressure can be adjusted according to the process requirements. The pressure varies from 1 to 7 bar. The spray gun is controlled by a pressure regulating valve and equipped with a pressure gauge. The air compressor is required to meet the air pressure of not less than 7 bar, and the 12 spray guns must be equipped with a flow rate of 12 m3. /min Dry compressed air (owned by the user) and equipped with a 1m3 gas tank. One dryer.

Energy allocation and consumption:
1. 1 centrifugal fan: power 7.5kw;
2. One spray gun swing motor: power 0.4kw;
3. One turntable motor: power 1.5kw;
4. One horizontal spiral motor: power 0.75kw;
5, upgrade the gear motor 1 set power 2.2KW
6, lighting and control circuit: power about 0.25kw;
7, the total power of the machine: In addition to the air compressor, about 10.5kw.
