Environment-friendly energy-saving chip water-scrubbing process and production line apparatus

Abstract

The invention discloses an environment-friendly energy-saving chip water-scrubbing process, comprising the following procedures: 1, a chip water-scrubbing procedure in a rinsing machine; 2, a dehydration procedure of water and chips in a screw dehydrator; 3, a slag-water separation procedure performed on water, silt, fine suspended matters and the like discharged from the screw dehydrator, which includes three steps of: (1) separating out the suspended matters and coarse soil sediments; (2) precipitating the silt; and (3) filtering the water; and 4, a procedure of feeding the filtered water back to the rinsing machine. The invention also discloses an environment-friendly energy-saving chip water-scrubbing production line apparatus comprising the rinsing machine, the screw dehydrator, a revolving grate, a rotary liquid tank and a fine filter, all of which are orderly communicated with each other, wherein the water outlet of the fine filter is communicated with the water inlet of the rinsing machine through a circulating water tank provided with a water pump. The process and the apparatus of the invention, compared with the traditional process and the traditional apparatus, are lower in production cost, and further meet the water scrubbing requirements for the chips and greatly reduce drainage of sewage, thereby reducing pollution on the environment.

Description

(1) Technical field: [0001] The invention relates to the cleaning of wood chips during the preparation of wood-based panels, in particular to an environmental-friendly and energy-saving wood chip water washing process and production line equipment. (2) Technical background: [0002] The existing traditional wood chip washing process, such as the invention patent of "Wood Chip Washing Process and Wood Chip Washing Equipment" with the patent application number of 200410022032.8, only completes the cleaning of wood chips, and does not take effective measures to treat the slag water after washing, resulting in The separation of slag and water is not clean, which seriously affects the next step of recycling and the long-term work of the equipment, forming a large amount of waste water that needs to be discharged, causing environmental pollution and water waste, and increasing production costs. (3) Contents of the invention: [0003] The object of the present invention is to pro...
