Abstract

The invention discloses a rotary drum type efficient pulp washer which comprises a housing and a first variable frequency motor. A rotary drum is arranged in the body and is rotatably connected to the housing through a bearing; the inner diameter of the rotary drum is gradually reduced from left to right, a spiral blade is arranged in the rotary drum, a discharge pipe communicates with the right side of the rotary drum, the discharge pipe is horizontally arranged, and meshes are uniformly formed in the side wall of the discharge pipe. By arranging spiral blades which are different in spacing distance and size, pulp slurry is quickly dehydrated and collected, a scraper which damages a filter screen is not used, and the service life of the device is prolonged; the filter holes are prevented from being blocked through the rotary drum and the rotary spiral blades, so that continuous production is guaranteed, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a drum-type high-efficiency pulp washer. Background technique [0002] Vacuum pulp washer is a common pulp washing equipment, suitable for various pulps such as wood pulp and straw pulp. It is the key technical equipment for solving wastewater pollution and implementing alkali recovery projects in the paper industry. It is composed of distributing valve, washing device, depulping device, net washing device, transmission device, and screw conveyor, which can be used individually or in series. [0003] The traditional pulp washing machine mostly uses a scraper to collect the pulp, which will damage the filter screen, cause the finished pulp to leak, reduce the service life of the filter screen, and need to replace the filter screen frequently, which affects the washing efficiency and effect. In addition, the filter screen is prone to clogging , causing interruption of washing and affect...
