In order to achieve the purpose, the large-inclination-angle dry sludge conveying device comprises a conveying cavity, a helical blade, a central stop block and a motor;
the material conveying cavity is obliquely distributed, a feeding hole is formed in the top of the lower end of the material conveying cavity, a discharging hole is formed in the bottom of the higher end of the material conveying cavity, spiral blades are arranged in the material conveying cavity, a plurality of central stop blocks are arranged on the spiral blades, and an output shaft of the motor is connected with the spiral blades.
The motor is positioned at the higher side of the material conveying cavity.
The central stop blocks are sequentially distributed along the axial direction of the helical blade.
All the central stop blocks are distributed at equal intervals.
The inclined angle of the material conveying cavity is more than or equal to 30 degrees.
When the sludge conveying device works, dry sludge enters the conveying cavity through the feeding hole and is fed into the discharging hole under the action of the helical blades and the central stop block.
The dry sludge is prevented from returning from the center of the helical blade by the central stop block.
The motor drives the helical blade and the central stop block to rotate in the material conveying cavity.
The invention has the following beneficial effects:
when the large-inclination-angle dry sludge conveying device is in specific operation, the motor is started, the motor drives the helical blade and the central stop block to move in the conveying cavity, dry sludge enters the conveying cavity through the feeding hole, the dry sludge is conveyed from the lower part of the conveying cavity to the discharging hole under the action of the helical blade and the central stop block, and when the dry sludge rises in the conveying cavity, the central stop block can effectively prevent the dry sludge from returning from the center of the helical blade, so that the conveying efficiency of the sludge under the large-inclination-angle condition is greatly improved, the occupied area is saved, the investment cost is saved, and the conveying problem of the dry sludge under the large-inclination-angle condition is solved.
