The wet curtain polishing, grinding and dust - collecting all - in - one machine adopts the arc structure based on the theory of fluid mechanics (such as water, wind, gas, etc.) and the water circulation design. The polishing machine is composed of four major parts: the outer box, the centrifugal fan, the water pump, and the electric control interlocking control system. The box is made by welding steel plates, and the other parts are assembled with screws. The whole machine of the curtain - type polishing and dust - removing all - in - one machine is beautifully designed, with a compact structure, small volume and light weight, and has the characteristics of convenient installation, maintenance, operation and use.
Dusty gas enters the dust collector from the inlet. The airflow turns downward and impacts on the water surface, and some larger dust particles fall into the water. When the dusty gas passes through the "S" - shaped channel between the upper and lower blades at a speed of 10 - 15 meters per second, a large amount of water splashes are stirred up, making the water and gas fully contact. Most of the fine dust particles are mixed into the water. Due to the centrifugal force, the dusty gas forms a vortex chamber in the "S" - shaped channel. In the vortex chamber, the whole flow direction changes, thus generating the necessary relative movement between dust particles and droplets, which becomes an effective dust - removing process. After leaving the vortex chamber, the dusty droplets and the purified gas pass through the mist - liquid separation chamber to remove water droplets and then are discharged from the dust - collecting unit through the ventilation opening. An explosion - proof lighting lamp with an illuminance > 800 is installed on the upper part of the wet curtain polishing, grinding and dust - collecting all - in - one machine to facilitate the operation of the staff. After the wet curtain polishing, grinding and dust - collecting all - in - one machine has been used for a certain period of time, a certain amount of sediment will accumulate inside. The staff must regularly open the maintenance door to clean the sediment, and the dust accumulation on the inner wall must be < 11mm. The wet curtain polishing, grinding and dust - collecting all - in - one machine ensures the safety and explosion - proof of the dust - removing environment for explosive dust, ensures the safety of the employees' production environment, improves the utilization efficiency of the grinding position, and also improves the production efficiency.
