Machine tool casting dry spray booth
The spray booth is a device that provides a special environment for painting operations. The artificial environment created in the paint booth can meet the needs of the painting operation on the temperature, humidity, illuminance, cleanliness, etc. of the environment; create a relatively comfortable and safe work for operators Environment: It can handle the paint mist generated by the painting operation and protect the sprayed material from secondary pollution. In other words, it is to make the floating paint particles (mist particles) generated during spraying and painting to be taken away from the spraying site in time. , to ensure the spray quality. The spray booth is equipped with a paint mist treatment device, and the exhaust gas treated by the paint mist treatment device meets the national emission standards to prevent environmental pollution.
The spray booths are roughly divided into dry spray booths, wet spray booths, water curtain spray booths, water wash spray booths, oil wash spray booths, pumpless spray booths, water spin spray booths, etc.
Dry treatment of paint mist particles generally goes through the steps of exhausting, capturing paint mist particles with filters, adsorbing mist particles with baffles, and forced ventilation. The baffle should be cleaned afterwards, and the filter should be replaced frequently, which is not suitable for large-scale painting.
The wet water curtain absorbs or adsorbs paint mist particles, the spray booth can be used continuously for a long time, the paint mist purification efficiency is high, the operation and maintenance are simple, the installation is flexible and convenient, no waste water discharge, clean and safe, and high superiority.
The water curtain spray booth uses the positive and negative pressure of the atmosphere to install an air inlet above the operator's head. Install a water curtain wall in front of the spray booth. A high-power fan is installed behind the water curtain wall to extract air. Air convection is formed from the top of the head to the back of the water curtain wall. The air filters free paint particles into the water through a water curtain.
The water cyclone spray booth uses the principle of water-gas two-phase mixing to fully mix the paint particles in the air with water through the paint mist filter device, circulating water pool and exhaust fan under the floor grille of the spray booth, and finally the paint particles are Leave in water for safe and efficient handling of paint mist during spraying operations.
Wet spray booths, water curtain spray booths and water spin spray booths must be equipped with circulating water systems, which include: circulating water pumps, circulating pools, grilles, and circulating water dosing equipment. A large amount of paint mist generated during the spraying process enters the circulating water through the thorough mixing of wind and water. The water with paint flows back to the water tank, and the paint mist coagulant is added to the water tank to separate the paint residue and water, so that the circulating water can be purified.
