Embodiment Construction

[0023] Attached below figure 1 And specific examples further illustrate the content of the present invention.

[0024] Such as figure 1 As shown, the papermaking waste slag squeezer of the present invention has a power box 1, a transmission shaft 2, a bearing seat 3, a conical screw shaft 4, a filter net cylinder 5, a lining net cylinder 6, a rib frame 7, a casing 8, an anti-slip out Material port 9 and other parts. The conical screw shaft adopts a variable-diameter and variable-pitch structure, which is conical. The casing and the filter cylinder are multi-layer combined conical casing structure. The whole conical casing is mounted on one end face of the bearing seat by cantilever through bolts, and the anti-slip discharge port 9 is installed on the small end of the conical casing to discharge the material. Mouth. The inner section of the anti-skid outlet 9 is a regular hexagon.

[0025] When working: the conical screw shaft 4 rotates towards the set direction at a certa...

Abstract

The invention discloses a waste residue drying machine which comprises members such as a power-control box, a transmission shaft, a bearing support, cone-shaped screw shafts, a multi-layer cone-shaped combined shell and an anti-slip discharge port. The papermaking waste residue drying machine is characterized in that a filter screen barrel and the multi-layer cone-shaped combined shell are of sleeved cantilever structures, a feed port is arranged at one side upwards a big end of the cone-shaped shell, and a small end of the cone-shaped shell is connected with the anti-slip discharge port. The cone-shaped screw shafts which are conical are of diameter-variable and screw pitch-variable structures. The cone-shaped screw shafts and the shell are in horizontal cantilever-type assembling, a big end of the assembling is supported by the bearing support, and a small end of the assembling is suspended. The papermaking waste residue drying machine is developed and designed aiming at biomass materials of the papermaking waste residues and the like, is unique in structure, high in drying effect, big in dehydration dryness, wide in application, and can not only be applied to the dehydration dryness of the papermaking waste residues, but also be used for realizing strong efficient dehydration of other biomass wastes of waste pulps and sludge and the like.

Description

technical field [0001] The invention relates to a papermaking waste residue squeezer, which belongs to the pulp and paper industry and is used for squeezing papermaking waste residue and other biomass waste. Background technique [0002] Raw materials for pulping and papermaking need to be washed to remove impurities. For example, after wood chips, reed chips and grass chips are washed in the wood and non-wood fiber preparation process, a large amount of biomass waste such as wood chips, reed residues and debris will be produced. These impurities contain water, which are not easy to recycle, are not conducive to direct co-fired power generation, and are loose in size, occupy a large space, and are not convenient for loading and transportation, which has become a major problem in polluting the environment. This situation is very common, and paper mills generate a variety of biomass residues every day that need to be recycled. Although there are many kinds of commonly used or...
