Inclined cylinder screening machine for pulping industry

Abstract

The invention relates to an inclined cylinder screening machine for pulping industry. The inclined cylinder screening machine comprises a shell, a screen drum, a main shaft and a motor transmission set; the shell is of a cylindrical structure with an opening at one end; the axis is in an alpha angle with the horizontal plane; supporting legs support the bottom of the shell; the screen drum is of acylindrical screen drum structure, wherein the inner cavity of the screen drum is provided with a spiral blade, the screen drum is installed in the cylindrical structure through the opening end of the shell, and the axis of the screen drum coincides with the axis of the shell; one end of the main shaft is inserted into one side, far away from the opening end, of the shell and is fixed with one end of the screen drum through a flange; the other end of the main shaft is in power connection with the output end of the motor transmission set; the other end of the screen drum is a slag dischargingend, and a slurry inlet pipe and a dilution pipe are inserted into the inner cavity of the screen drum for feeding and diluting slurry through the slag discharging end; and the bottom of the shell communicates with a slurry outlet chamber, wherein the separated slurry flows out of the slurry outlet chamber. The manufacturing cost is reduced, the working noise is low, and the maintenance amount isreduced. The screen drum is in an alpha angle with the horizontal plane, namely, the screen drum is inclined to the horizontal plane by a certain angle, so that the collection rate of recyclable fibers can be improved.

Description

technical field [0001] The invention relates to the technical field of papermaking pulping screening devices, and more specifically relates to an inclined cylinder screening machine used in the pulping industry. Background technique [0002] The pulping process of waste paper raw materials generally undergoes primary disintegration by a hydraulic pulper, and the hydraulic cleaning machine extracts pulp containing a small amount of light impurities such as plastics and styrene foam from the hydraulic pulper tank for processing: the good pulp fibers pass through the hydraulic cleaning machine The secondary dissociation of the liquid is directly pumped to the slurry tank through its sieve plate; light impurities such as plastics and styrene foam accumulate in the water cleaning machine, and finally are periodically pumped to the cylindrical sieve by the water cleaning machine. The drum sieve rotates and is brought to a high place, and falls down again due to the action of gravi...
