Problems solved by technology
The winnowing method requires multiple fans, pipelines and cyclone separators, which requires a lot of equipment, high energy consumption, and low moisture content of wood chips, which has a great impact on subsequent processes; while the general washing method consumes a lot of water and is difficult to treat sewage. Many devices, high power consumption, high failure rate

The invention relates to a wood chip washing device and a using method thereof, and belongs to the technical field of manufacturing of artificial boards. According to the technical solution, an arc-shaped track is arranged in a water tank body, one end of the arc-shaped track is fixed to a cover plate (16), the other end of the arc-shaped track is fixed to an outlet slideway (14), holes are distributed all over the arc-shaped track, and an opening (17) is formed in the arc-shaped track; the upper portion of a waterwheel rotary table is located outside the water tank body and is matched with adischarge outlet of a hopper (4), and the lower portion of the waterwheel rotary table is located in the water tank body and is adjacent to the arc-shaped track; and an annular groove and scraper plates are arranged on the outer edge of the waterwheel rotary table, the annular groove is formed by two circular side plates and a base plate, the two circular side plates are separately arranged on thetwo sides of the base plate, and the multiple scraper plates (53) are uniformly arranged in the annular groove in the circumferential direction and divide the annular groove into a plurality of storage grooves. According to the wood chip washing device and the using method thereof, wood chips are cleaned and soaked, so that the moisture content of the wood chips is increased, stone impurities inthe wood chips are removed, water consumption is reduced, and the quantity of generated waste water is reduced.
Description
technical field [0001] The invention relates to a water washing device for wood chips and a method for using the same, belonging to the technical field of wood-based panel manufacturing. Background technique [0002] When manufacturing wood-based panels, the wood chips used as raw materials must be cleaned to remove impurities such as sediment, stones, and iron in the wood chips, and there should be a certain moisture content in the wood chips to reduce thermal grinding power consumption and improve fiber quality. . [0003] At present, there are generally two ways to deal with wood chips. One is to use dry cleaning. After the wood chips are screened and magnetically separated, the stone impurities with heavier specific gravity are selected by winnowing; the other way is to use water washing. , After the wood chips are screened and magnetically separated, they enter the washing machine to stir to remove stone impurities, and then squeeze out the excess water through the deh...
