Description
Technical Field
The invention belongs to the technical field of die casting machines, relates to a die casting machine purifying device, and particularly relates to a die casting machine water mist collecting and purifying device.
Background
The die casting machine is a machine for pressure casting, and comprises a hot pressure chamber and a cold pressure chamber, the die casting machine injects molten metal into a die to be cooled and formed under the action of pressure, and a solid metal casting can be obtained after die opening.
After the die sinking of the existing die casting machine, the mechanical arm is generally adopted to control the spray head to move, and the cooling water is sprayed on the die, so that the water spraying cooling of the die is realized. Because the temperature of the mold is too high, water is vaporized to form a large amount of water vapor, and the water vapor is also mixed with a plurality of waste gases generated by release agents and the like. The water vapor can cause the interior of the workshop to be too wet, so that the equipment is easy to rust, the environment of the workshop is polluted, and the health of workers is influenced.
In order to solve the technical problem, someone has proposed a die casting machine oil mist waste gas collection mechanism (201922301819.2), including installing the supporting seat on the die casting machine, be equipped with on the supporting seat and collect the cover, collect the cover and be opening funnel shaped structure down, collect the cover and cut apart into fixed part and removal portion from the middle part, the fixed part is fixed on the supporting seat, its top is equipped with the flange mouth, the below of removal portion is equipped with slider and guide rail, slider and guide rail are fixed respectively on removal portion and supporting seat, slider and guide rail sliding connection. The flanged port is for connection to an external exhaust treatment system.
Although the oil mist waste gas collecting mechanism of the die casting machine can reduce waste gas diffusion, the mechanism still has the following defects: 1. exhaust gas and mist easily leak from between the fixed part and the movable part, thereby affecting the mist and exhaust gas collection rate. 2. The flange port is positioned on the top wall of a fixed part, the fixed part is usually arranged above a fixed machine head of a die casting machine, and a large amount of water mist and waste gas are generated by cooling the fixed die and a movable die; and moreover, the mold is in an open state during cooling, the distance between the movable mold and the flange opening is large, so that a large amount of water mist and waste gas generated by the movable mold are cooled, and the collection rate of the water mist and the waste gas is further influenced. 3. The pipe diameter of the flange opening is usually small, and is generally not more than 30cm; therefore, the pressure difference between the flange opening area and other areas is large, namely the air pressure of the collecting cover is uneven, dead zones are easily generated, water mist and waste gas are easily overflowed, and the water mist and waste gas collecting rate is further influenced. 4. Collect the cover and pass through the pipeline and be connected with outside exhaust-gas treatment system, this not only can increase the air current flow resistance, influences water smoke and waste gas collection rate, still can make water smoke condense at the pipeline inner wall, and a large amount of water drops downwards in flange mouth department, and then drips on the die casting machine.
