A beating and sorting integrated machine using a rotary drum screen

Abstract

The invention belongs to the technical field of garbage treatment, and relates to a beating and sorting integrated machine using a rotary drum screen, which has a complete machine base, a main shaft support, a main shaft bearing seat, a rolling screen, a rolling screen outer cover, and a main shaft bearing. Three end covers, main shaft transmission pulley, main shaft motor, main shaft; it is characterized in that it also has a main shaft bearing first end cover, a main shaft bearing, a main shaft bearing second end cover, a rolling screen drive motor, a large ball bearing, and a rolling screen driving drive Gear, left large bearing inner ring support, rolling screen driven gear, left large bearing outer ring support, large bearing first end face oil seal, right large bearing inner ring support, right large bearing outer ring support, large bearing The second end surface oil seal, material inlet, material beating chamber, end cover of material beating chamber, slurry output port, slag material and inorganic matter outlet, rolling screen transmission claw. The invention has the following main beneficial technical effects: balls are evenly distributed, corrosion is reduced, wear is slower, and the service life is longer.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to an integrated beating and sorting machine adopting a rotary drum screen. Background technique [0002] In the garbage disposal class machinery of prior art, please see Figure 8 The two ends of the rolling screen are connected to the outer rings of two large slewing bearings. Due to structural and transmission reasons, they can only be connected to the outer rings of the slewing bearings, while the inner rings are fixed on the frame wall. This structure , so that the entire slewing bearing is exposed to the working medium, the working medium is in contact with the body of the slewing bearing, and the working medium may enter the raceway of the slewing bearing. At the same time, there is no cage between the balls of the slewing bearing, and only a small Isolation block, the entry of working medium will accelerate the wear of the isolation block. The slewing b...

Problems solved by technology

But in the same kind of beating and sorting machines, the slewing bearings all work in the vertical plane. Due to the stress situation and the structure of the slewing bearing itself, the balls in the slewing bearing tend to concentrate downward. The concentricity of the inner and outer rings There is a tendency to deviate; when the spacer between the balls is worn to a certain extent, the balls will concentrate downwards, resulting in uneven distribution of balls on the upper part of the slewing bearing, which will cause excessive deviation of the concentricity of the inner and outer rings of the slewing bearing, resulting in If the rotation is difficult, the machine needs to be overhauled and the slewing bearing replaced, and the service life is quite short

Therefore, the beating and sorting machine with a slewing support structure has this inherent defect of a particularly short life, and the industry expects to solve the above problems
