Summary of the invention

The purpose of this utility model is for overcoming above deficiency, when being raw material with cow dung, pig manure etc. in the biogas engineering, but provides the multiple stage crushing device of the high and desanding of a kind of degree of crushing.

A kind of biogas engineering multiple stage crushing device that is used for, it is characterized in that having the positive truncated rectangular pyramids shape material feeding box of a upper and lower opening, be provided with the vertical cylinder of a upper and lower opening under the material feeding box, the material feeding box end opening is connected with vertical the suitable for reading of cylinder, vertical cylindrical wall is opened symmetrical circular hole respectively, there is a horizontal driven shaft from this circular hole, to pass, the end that driven shaft stretches out vertical cylinder is provided with driven pulley, on the driven shaft of vertical cylinder interior, tool section is housed, vertical cylinder below is provided with a horizontal cylinder, laterally cylinder has an opening over against vertical cylinder end opening place, connect with vertical cylinder end opening, be provided with a desanding mouth in horizontal cylinder bottom, laterally cylinder end face of cylinder and orifice plate center are opened the hole respectively, have a driving shaft to pass from this through hole, the end that driving shaft stretches out horizontal cylinder links to each other with the output of reductor by shaft coupling, the output of the motor reductor of ining succession, the other end is provided with a driving wheel, and driven pulley is connected by belt with driving wheel; Inside at horizontal cylinder, along driving shaft from driving wheel the output to reductor, helical blade, two-layer blade, mill cutting knife are arranged respectively, blade becomes 10～30 ° angle with the driving shaft axis, on the position of blade, the rectangle section laterally is housed on the cylinder inner wall, leaves the space between blade and the rectangle section, between mill cutting knife that is equipped with on the driving shaft and orifice plate, leave the slit.

The utility model is simple in structure, drives raw material conveying, fragmentation thereby adopt single power source to drive the driving shaft rotation, and the fragmentation of driven shaft relies on driving shaft power driven rotary, thereby the disintegrating machine energy consumption is low, and is good to the bulk raw crushing effect; The desanding mouth of disintegrating machine can be removed the sandstone in the raw material, and having remedied common disintegrating machine can not desanding and cause the susceptible to plugging deficiency of subsequent treatment process.It is the fragmentation and the desanding of raw material that this breaker can be widely used in the biogas engineering with cow dung, pig manure etc., has promotional value.
