Filtering device for wood fiber powder

Abstract

The invention relates to the technical field of wood fiber production equipment, and discloses a filtering device for wood fiber powder. The filtering device comprises a screening box, a fixing frameis fixedly connected to the top of the screening box, a first motor is fixedly connected to the top of the fixing frame in a sleeved mode, a rotating rod is fixedly connected to an output shaft of thefirst motor through a coupler, and a bearing is fixedly connected to the middle of the surface of the top of the screening box in a sleeved mode. According to the filtering device for the wood fiberpowder, the problem that wood chips and sand in the wood fiber powder are filtered insufficiently is solved, the first motor, the rotating rod, the bearing, a carrying box, a feeding pipe, screening pipes, first screening plates, first filtering holes and second filtering holes are arranged, large wood chips in the wood fiber powder are filtered out through the first filtering holes, then sand inthe wood fiber powder is filtered out through the second filtering holes formed in the surfaces of the first screening plates, and therefore the effect of filtering the wood fiber powder is achieved.

Description

technical field [0001] The invention relates to the technical field of wood fiber production equipment, in particular to a filter device for wood fiber powder. Background technique [0002] Lignocellulosic fiber is an organic flocculent fibrous substance obtained from natural renewable wood through chemical treatment and mechanical processing. It is widely used in concrete mortar, gypsum products, wood pulp sponge, asphalt roads and other fields. It has good effects on preventing coating cracking, improving water retention, improving production stability and construction suitability, increasing strength, and enhancing adhesion to the surface. Its technical functions are mainly: thixotropy, protection, absorption, carrier and filler. [0003] In the production and processing of wood fiber powder, because some larger particles of wood chips and sand remain in the wood fiber powder, the production quality of wood fiber powder is affected due to insufficient filtration of wood ...
