How the shot blasting machine can better collect dust and enter a low resistance operation state

During the operation of the shot blasting machine, part of the steel grit is inevitably scattered around the working area of the shot blasting machine. The floor shot blasting machine mechanically throws the steel shots onto the working surface at a high speed and at a certain angle, causing the steel shots to hit the road surface, making the road surface rough, and removing residues. The dust collector produces steel shots and impurities. After cleaning, the negative pressure will be Recycling, the complete steel shots will be automatically recycled, and impurities and dust will fall into the dust box. Pass through type shot blasting machine can continuously carry out descaling, cleaning and pretreatment of steel plates, steel materials, steel beams, steel profiles, steel pipes, steel castings and other steel materials. Shot blasting machine refers to casting equipment used to clean or strengthen the surface of castings with high-speed steel shots thrown by blasting machine.

The dust-laden airflow enters the canister from an inlet located at the upper part of the dust collector, and due to the sudden expansion of the airflow part, the deflector in the canister forces the air to flow downward through the filter tube. Some coarse particles in the airflow sink under the action of gravity and inertial force. After fine particles and small-density dust particles enter the filter, the dust is deposited on the surface of the filter through a combination of diffusion and sieving filtration. When dust accumulates on the surface of the filter material and the resistance reaches the set value, the pulse valve hits, compressed air is directly injected into the filter element, and the filter tube makes the ash pulsate. When dust accumulates more and more on the surface of the filter material, the resistance reaches the set value, and a series of pulses are used to clean the filter tube. The dust collected in the ash hopper is continuously discharged through the ash discharge valve. In the maintenance process, the filter can be easily removed by manually turning the handwheel on the repair cover, which makes it easier to remove the dust collected in the ash and return to the low resistance operation state. The dust collected in the ash is continuously discharged through the ash discharge valve.

The shot blasting machine can sand, core and clean castings at the same time. Some areas are also called sand machine and sandblasting machine. The steel grit scattered on the ground not only threatens people's safety, but also pollutes the steel grit. Long-term accumulation on the ground will rust and cannot be used. The collected gravel cannot be stored. When it needs to be put into use as soon as possible, the amount of sand used for shot peening cannot be filled in a short time. To solve this series of problems, we built a stainless steel grit, removed the pipe from the equipment, and installed a pull-down device at the bottom. The sewage tank is configured to convert the bottom into a cone shape, and is installed on a subassembly of the upper part of the explosion chamber, and a transition hole is cut in the upper part of the explosion chamber corresponding to the hole, and it is stored. Such a complete shot blasting machine-steel sandblasting machine, sand storage device, and sorting device are all manufactured. The operator of the shot blasting machine can use the working time of the shot blasting machine to extract and adjust the people in the steel shots. Collect steel grit near this area, add it to the reservoir through a movable register, and simply open the lowering device of the storage chamber before the next injection. The right amount of steel grit can be injected into the steel shots chamber. This transformation solves many problems of sand mining, storage and filling of the shot blasting machine, greatly improves the utilization rate of steel grit, reduces the production cost, and improves the working efficiency of the shot blasting machine.
