Technical Field

The utility model relates to an engineering field especially relates to a conveyor is collected to lacquer sediment.

Background

Paint residues are mainly generated in some coating production lines, such as coating lines of automobile manufacturing, containers, engineering machinery, electronic products and the like. In the spraying process, paint that oversprays can fall into the circulating water of below to under the coating cloud coagulant and the flocculating agent effect of circulating water, form the lacquer sediment come-up, scraped the sediment machine and scraped the back through the sediment fill that falls, fall into the lacquer sediment braided bag of below in, the braided bag is put into the lacquer sediment incasement, gets into the lacquer sediment incasement through the braided bag waterlogging caused by excessive rainfall, and water is discharged from lacquer sediment case bottom valve again. Paint slag is generally used as hazardous waste and is finally incinerated for disposal, and the cost is very high, so that a plurality of manufacturers develop and produce paint slag dewatering equipment, and the water content of the paint slag is reduced by adopting methods such as extrusion, centrifugal force, vacuum filtration, heating drying and the like, so that the aim of reduction is achieved, and the disposal cost is saved. Therefore, a paint slag conveying device is required to convey paint slag to the dewatering equipment. The water content of the paint slag just hung from the slag scraper reaches more than 98 percent, but the paint slag can sink quickly due to large specific gravity, and the paint slag can be bonded and agglomerated under the extrusion action of water pressure and self gravity after sinking, and can quickly cause blockage, so that the paint slag is difficult to be directly conveyed by pumps such as a water pump, a diaphragm pump, a screw pump and the like. If adopt equipment such as conveyer belt, scraper blade machine to carry, though can not have the jam problem, the sediment slab knot problem of lacquer still can lead to conveyer belt or scraper blade to have attached to too much lacquer sediment and can't effectively carry the lacquer sediment, can lead to the card to die even.
