Sandblasting room
a.The blasting room is built with color-coated steel sandwich boards in a steady and sturdy light-steel structure. Hard-wearing rubber protective boards are attached onto the inside wall of the room in the purpose of protecting the room walls from being damaged by the sand blasting.
b.SandBlast Room are designed and fabricated according to the size requested by the customer.
c.They may have one or two main doors for material access. The structure of the room may consist either of steel walls or color sandwich panels with polyurethane insulation.
d.The internal walls are lined with wear-proof rubber. The floor is made of steel grating which cover the automatic recovery system for abrasives. The material handling can be done by trolleys or by overhead crane.
Portable Pressure Pot Sandblaster
a.Portable Pressure Pot Sandblaster is powered with compressed air, the abrasive media is accelerated to 50-60m / s impact to the workpieces’ surface, it is a non-contact, less non-polluting method of surface treatment.
b.Portable Pressure Pot Sandblaster
c.The system is installed with 1-2 pcs peach-style pressure tank and designed to increase steel grit fluidity.
d.The upper part is connected with a pneumatic butterfly-style valve and a storage bin. The pneumatic valve is closed during the blasting operation and opened to input shots at the end of the blasting.
e.The pipeline is equipped with a manual air on-off valve, oil-water separator, pressure regulator, pneumatic diaphragm valve, gas storage tank, riot device, exhaust muffler and sand valve etc.
f.2 or more tungsten carbide blasting guns, with a 10-meter-long sandblasting hose connected to each gun.
Abrasive Recovery System
The abrasive recovery system for blasting room consist of floor recovery, bucket elevator and separator.
1.Floor recovery system
Sandblast room recovery system use floor recovery system to reclaim the used blasting media and contaminants into the bucket elevator and then into the dust collector system, and then the cleaned abrasive get into the storage hopper to recycle, the residual will get our of the recycle system from the separator.
2.Bucket elevator system
a.The dismountable elevator is driven by 1 gear motor at the top of the elevator and built with steel plates by accurate soldering technique and It includes 2pcs high-quality wheel hubs, 1 elevator body, 1 high-performance and durable belt and several alloy buckets.
b.The maximum transfer amount of the elevator is 120Ton/H. It collects and lifts the shots recycled by the screw conveyor onto the separator and storage cabinet.
c.A window is designed on the elevator for easy maintenance and examination.
3.Separator system
a.The air-flow separator is used to separate good shots and broken shots and dust. It is built and soldered with steel plates and different chambers inside to lead the air flow and multi-level steel plates to adjust and balance the sliding shots flow amount.
b.Shots & dust mixture is transported from the screw conveyor and go downward on a sliding steel board and get into the way of the air flow. Good shots are heavy and not driven to move by the air flow but broken shots are much lighter to be lead to the other slide board that connected with a broken shot collector/bucket. Dust directly flows in the air flow direction and is taken to the air outlet to be dealt with by the dust collector.
Sweep/Shovel Chute Type
Sweep/ shovel chute type is the most economical abrasive reclaim system, which is only appropriate for low production operations.This is the simplest reclaim system, but need to collect the abrasive and push the abrasive into the recycle system manually after blasting work.This blasting room recovery system just need a small pit for elevator, no need other foundation pit, no damage to the ground.
Single Screw or Scraper Partial Reclaim System
The most economical floor design is available. The system contains one or more screw conveyor or craper conveyor, heavy-duty screw belt and bucket elevator, air-wash separator, and oversized abrasive storage hopper with a caged man ladder and handrail. This can be expanded to an "H", "U", or full floor reclaim system, which is best suited for low to medium production levels.
"L"- Shaped Partial Reclaim System
One longitudinal conveyor installed at the one sidewall of the blast room is allowing the abrasive delivered from the spray guns, which is either blown or rebounded off the workpiece, to strike the side walls and fall into the conveyors, automatically reclaiming approximately 40-70 percent of the blast media. The reclaiming abrasive on the blast booth floor is pushed into the screw or scraper conveyors assemblies at the end of the work shift. The "L" shaped floor design is typically used in a “flow-through” room configuration where heavy workpieces and/or material handling devices can drive into the room. This is best suited for low to medium production.
"H" - Shaped Partial Reclaim System
Two sets of longitudinal conveyors installed at each sidewall of the sandblast room allowing the abrasive delivered from the spray guns, which is either blown or rebounded off the workpiece, to strike the side walls and fall into the conveyors, automatically reclaiming approximately 60-90 percent of the blast media. The reclaiming abrasive on the floor is pushed into the screw or scraper conveyors assemblies at the end of the work shift. The “H” shaped floor design is typically used in a “flow-through” room configuration where heavy workpieces and/or material handling devices can drive into the room. This is best suited for medium to high production.
"U"- Shape Partial Reclaim System
Two longitudinal screw or scraper conveyors assemblies along each wall of the blast room and positions the cross screw or scraper conveyors along the back wall of the blast room. This allows the abrasive delivered from spray guns, which is either blown or rebounded off the workpiece, to strike the sidewalls and back wall of the blast room and fall into the reclaim system, A “U”- shaped floor design will automatically reclaim 60-90 percent of the blast media. The remaining abrasive on the floor is pushed into the metered shed plate screw assemblies at the end of the work shift, The “U”-shaped floor design is typically used in an “in-out” room configuration where heavy workpieces and/or material handling devices can drive into the room. This is best suited for medium to high production.
Full Floor Partial Reclaim System
The full-floor reclaim system utilizes multiple screw assemblies or scraper assemblies to create a fully automatic, high volume abrasive reclaim system where 100% of the abrasive blast media is returned to the separator system during the blasting operation. This allows for a faster reclaim as well as full recycling of the abrasive media, saving your blasting operation both time and cost.
The Full Floor Reclaim System allows for the maximum efficiency of your abrasive blast system. This abrasive blast reclaim system is well suited for pass-thru and/or high production requirements.
Dust Collector System
1.It includes cyclone separator and the cartridge filter. the cyclone separator separates most of heavy dust and the cartridge filter blocks and filters the escaped air & dust mixture.
2.Electromagnetic pulse technology is applied in the cartridge filter to shock and separate the dust from the filter. Dust goes down to the collect storage cabinet due to its gravity. Silencer and secondary filter ensure that noise emission is lower than 85DB and dust emission is lower than 50mg/m³
3.Wet dust collector, a high performance dedusting system with Venturi theory, especially for flammable and explosive media, automatically recycle dust.
