Working principle of large shot blasting machine equipment

　　Pneumatic recovery type sandblasting real estate is mainly composed of housing, sandblasting facilities, natural abrasive recycling device, ventilation and dust removal device, natural abrasive sorting device and electric control device. In order to simplify the facility, the natural abrasive recycling and the ventilation and dust removal can be combined. The fan passes through the honeycomb floor to suck the natural abrasive, dust, and airflow to the natural abrasive concentrated shower. The dust-containing gas is showered through the filter, and the dust adheres to the outer wall of the shower. The clean gas is discharged through the shower in a small batch to the outside of the workshop, and a small batch is circulated to the sandblasting room. The natural abrasive and heavy dust then pass through the natural abrasive trough to the sorter. The sorter has an inner and outer cone structure, and there is an adjustable channel between the inner and outer cones. After adjusting the core body, the air flow channel section can be changed, so the clutch ratio can be adjusted. The clutch process is as follows: When the natural abrasive and dust pass through the channel, due to the effect of gravity, the dust and gas enter through the gap between the cones and come out, while the natural abrasive and coarse particles fall to the vibrating screen under the cone. The vibrating screen further separates the natural abrasive and the coarse particles, and the separated pure natural abrasive passes through the screen holes into the designated hopper to the sandblasting tank for recycling. The dust and gas that have not been selected by oneself are then rinsed through a shower. The neat gas is discharged out of the workshop, and the dust falls into the waste hopper.

　　The effect of the use of crawler shot blasting machine

　　Through-type shot blasting machine is mainly used for fuel tank cleaning, ship hull cleaning, and cleaning of dome roof and inner and outer walls of spherical objects, paint removal, and specific cleaning of ship decks.

　　The pass-through shot blasting machine is easy to assemble and disassemble, and it can be quickly disassembled and installed within 20 minutes. The pass-through shot blasting machine can move up and down, left and right conveniently, and implements the automatic circulation of abrasives, and can feed without stopping the machine. And only one person can control production, which is very convenient. Reduce labor and improve production efficiency.

　　The parts in the through-type shot blasting machine:

　　1. Separator: The screw conveyor is mainly composed of a geared motor, a screw shaft, and a spiral shell. It adopts an outer spherical ball bearing with a square seat. The bearing can be automatically adjusted when subjected to vibration and impact, and has good sealing performance;

　　2. Pill delivery tube: It has a dual control function. A gate is set above each brake tube to cut off the pellets from the separator to facilitate the maintenance of the respective shot blasting device;

　　3. Shot blasting machine: mainly composed of rotating mechanism, impeller, cover, directional sleeve, blasting wheel, guard plate, etc.;

　　4. Blowing device: using a high-pressure fan and multiple sets of elastic blowing nozzles with different angles in the auxiliary chamber of the chamber to blow and clean the remaining projectiles on the surface of the workpiece;

　　5. Dust removal system: The dust removal system is mainly composed of a bag filter, a fan, and a dust removal pipeline.

　　The five component composition of the above-mentioned through-type shot blasting machine is also an important factor in the quality of the machine. A product that pays attention to details is a better product.

　　This machine integrates domestic and foreign technologies. It is a kind of cleaning equipment with good cleaning effect, compact structure, low noise, and is used for surface derusting or shot blasting in large and medium batch production. It has the following characteristics:

　　1. The cantilever centrifugal shot blasting device is adopted, which has the characteristics of long service life and simple structure.

　　2. Three ejection speeds of 75 m/s, 80 m/s, and 85 m/s are adopted.

　　3. The pulley adopts the internationally advanced quick-change structure, which is conducive to improving production efficiency and reducing labor intensity.

　　4. The BE type separator is used, which has a good separation effect and high productivity, and has a positive effect on improving the life of the blade.

　　5. Adopting a bag filter, the dust emission concentration is lower than the national standard, which improves the working environment of workers.

　　6. This model adds some special mechanisms such as manual pill gate and discharge gate.

　　7. The crawler shot blasting machine of this model can be used as a stand-alone machine or by wiring.
