Pre-treatment reaction bin used for rice and wheat straw fiber extracting

Abstract

The invention provides a pre-treatment reaction bin used for rice and wheat straw fiber extracting. The bin comprises a bin body, a first feeding opening is formed in the position, close to the side of the bin body, of the upper end face of the bin body, a first discharging opening is formed in the front side face of the lower portion of the bin body, three bearing rollers which are located on thesame horizontal plane are rotatably mounted below the first feeding opening, the axis lines of the bearing rollers are parallel to the direction from the rear side to the front side, a gap is reserved between the two adjacent bearing rollers, the periphery of each bearing roller is provided with multiple shifting teeth which protrude outwards in the radial direction, eight forward conveying screws which convey the straw from back to front and discharge the straw out of the bin body from the first discharging opening are rotatably connected to the position, below the bearing rollers, of the bottom in the bin body, the axis lines of the eight forward conveying screws are located on the same horizontal plane, and a material groove corresponding to each forward conveying screw is formed in the bottom face of the bin body correspondingly. According to the reaction bin, uniform heating, in-bin turning and smashing, stable discharging and free-lamping can be achieved.

Description

technical field [0001] The invention belongs to the field of related equipment for extracting rice and wheat straw fibers, and particularly relates to a pretreatment reaction chamber for extracting rice and wheat straw fibers. Background technique [0002] At present, the production of rice and wheat straw pulping is a project supported by the state. The traditional rice and wheat straw pulping process is pre-treated by washing with water, followed by high-pressure cooking, resulting in the production of a large amount of waste water and serious pollution to the water quality and ecological environment. The existing pretreatment and equipment functions of rice and wheat straw fiber extraction are not perfect, the efficiency is low, the energy consumption is high, the time is long, and the water consumption is high. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to propose a pretreatment device for the extraction process of rice and wheat stra...
