Sewage treatment device for conductive silver paste production

Abstract

The invention discloses a sewage treatment device for conductive silver paste production. According to the invention, a first partition plate, a second partition plate and a third partition plate arearranged in a treatment box; a first treatment chamber is formed between the first partition plate and the treatment box; a second treatment chamber is formed between the second partition plate and the first partition plate and in the treatment box; a third treatment chamber is formed between the second partition plate and the third partition plate and in the treatment box; a fourth treatment chamber is formed between the third partition plate and the treatment box; a first filter screen is arranged on the first partition plate; a second filter screen is arranged on the second partition plate;a third filter screen is arranged on the third partition plate; a first U-shaped pipe is arranged between and connected with the first treatment chamber and the second treatment chamber; a second U-shaped pipe is arranged between and connected with the second treatment chamber and the third treatment chamber; a third U-shaped pipe is arranged between and connected with the third treatment chamberand the fourth treatment chamber; a liquid inlet pipe is arranged at the upper end of the treatment box; and a liquid outlet pipe is arranged at the lower end of the treatment box. According to the invention, sewage purification treatment efficiency in the conductive silver paste production process can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of conductive silver paste sewage treatment equipment, in particular to a sewage treatment device for conductive silver paste production. Background technique [0002] As a functional printing material, conductive paste has been widely used in electronic information products due to its good physical properties. With the development of electronic products to be lighter, thinner, more functional and more environmentally friendly, its Performance also puts forward higher requirements. Among them, the low-temperature halogen-free conductive silver paste is widely used in membrane switches, capacitive electrodes, touch screens, etc. because of its excellent electrical conductivity, thermal conductivity, and practicability. Low-temperature conductive silver paste is a uniform paste made by stirring and dispersing conductive silver powder as a conductive filler with high polymer resin, solvent, curing agent, and a...
