Description

Technical Field

[0001] The present application belongs to the field of spraying technology, and in particular relates to a paint residue drying device. Background Art

[0002] The existing paint residue dryers on the market use the principle of indirect heating distillation separation to evenly heat the paint residue. The boiling point of the water in the paint residue is reduced to 60°C through a vacuum decompression device. After the water reaches the boiling point and vaporizes, it is recycled through a cooling system to obtain clean water. The paint residue (sludge) is continuously stirred during the process of water distillation and is evenly heated. After a period of time, the water is completely evaporated and the paint residue is dried.

[0003] However, the drying device in the prior art is too large in size and occupies a large area, which is not suitable for small space operation; the processing process is complicated and the cost is too high; and the entire process is closed, which is not conducive to operator observation and processing.

[0010] Preferably, the imperforate plate is connected below the vertical plate.

[0011] The non-porous plate can block the filtered water, ensuring that the water flows out from the outlet hole and preventing it from mixing with the paint residue again.

[0012] Preferably, the feed pipe is at an angle of 30-45 degrees to the horizontal plane.

[0013] The feed pipe has an inclined angle to facilitate the inflow of paint residue.

[0014] Preferably, the feed pipe is connected to the feed port by a flange.

[0015] Flange connection is used here, which is stable and easy to assemble and disassemble.

[0016] Preferably, a plurality of supporting legs are provided at the bottom of the hopper, and fixing holes are provided at the bottoms of the supporting legs.
