Coating waste filtering device

Abstract

The invention belongs to the field of coating waste treatment, and relates to a coating waste filtering device. According to the technical schemes of the invention, the coating waste filtering device comprises a material receiving box and a shell; the top ends of the material receiving box and the shell are open; one side of the bottom end of the material receiving box is connected with a liquid outflow pipe with a valve; the top end of the material receiving box is provided with the shell through a fixing frame; a liquid inflow box is installed in one side of the top end of the shell; two filter screen cylinders with driven gears are rotationally connected to one side wall of the liquid inflow box; a second motor located between the two filter screen cylinders is installed on the side wall of the liquid inflow box; an output shaft of the second motor is connected with a driving gear meshed with the driven gears; a residue receiving hopper is movably installed on the outer side wall of the shell; an opening in one end of each filter screen cylinder extends to the position above the residue receiving hopper; and a liquid guide box which is obliquely arranged and located below the two filter screen cylinders is installed in the shell. The device can be used for extracting and filtering filter residues in coating waste, is high in working efficiency, and can be used for drying the filtered solid waste at the same time.

Description

technical field

[0001] The invention relates to the technical field of paint waste treatment, in particular to a paint waste filtering device. Background technique

[0002] In people's daily life, paint is often used. Paint is commonly used by people. Paint slag is the discharge product of mechanical equipment coating, steel structure iron anticorrosion, wood and other objects, accounting for about 45% of the coating paint consumption. ~55%, which belongs to hazardous waste, which is toxic and flammable.

[0003] Most of the existing paint slag is treated by the paint slag treatment process. The paint slag treatment process: the paint slag in the spray paint sewage is now more commonly used as a paint mist coagulant. The paint mist coagulant is divided into two components: A agent and B agent. , the role in the treatment of spray paint sewage is to capture and decompose the spray paint slag in the circulating water system through the A agent, and then use the B agent to con...
