Stainless Steel Dump Sorter Screening Plate For Waste Pulp Light Impurities

Stainless Steel Dump Sorter Screening Plate For Waste Pulp Light Impurities

1. Introduction

Features: This machine is mainly used for the treatment of tailings in the screening section of the waste paper system. The incoming pulp concentration is about 1-3%, and the slag concentration can reach 20%. The processing efficiency is high, the fiber retention rate is high, and the recovery rate can reach 80. % Or more; only normal pressure operation is required, and it is a closed operation to avoid dirt splashing, save the cost of slag disposal, and fast long-term investment recovery.

3.structure introduction

1. The cylinder body is welded by steel plates, the part in contact with the slurry is made of stainless steel, and there are eight water spray pipes on both sides of the cylinder body.

2. The rotor is a rotating rod with 32 blades fixed on it.

3. The sieve plate is a combination of two semi-circular sieve cylinders with diameter Φ2.0-Φ4.5mm, which can be selected according to needs

The slag separator is mainly used for the treatment of tailings in the screening section of the waste paper system. The incoming pulp concentration is about 1-3%, and the slag concentration can reach 20%. The processing efficiency is high, the fiber retention rate is high, and the recovery rate can reach 80. % Above; only normal pressure operation is required, and it is a closed operation to avoid dirt splashing, save the cost of slag disposal, and fast long-term investment recovery.
Waste paper pulping has a large amount of impurities due to the different paper quality of the waste paper. The slag separator can remove light impurities and decompose small tablets in the fiber. It is not easy to block the sieve plate, and the user does not need to stop the operation frequently for cleaning.
The slag separator operates in a closed atmosphere under normal pressure, continuous slag discharge, no clogging and slurry splashing, no vibration, noise, no special supervision, fiber recovery rate of about 70%, slurry concentration of 1%-2%, slag discharge The concentration is 15%-20%, which is easier to operate and maintain than other tailing slurry treatment equipment.
Second, the structure and principle of the slag separator
The upper half of the slag separator is a vortex chamber, and the lower half is a semicircular screening area.
A high-speed rotating rotor is installed inside. The rotor is welded with axial sweeping blades and spirally alternately arranged sorting blades. After the slurry enters the slurry inlet, the high-speed rotor pats, scrapes, tears and peels the tailings. The comprehensive utilization of the slag is first thrown into the vortex chamber, and then scattered to the screening area to complete the separation process of fibers and impurities. At the same time, the nozzle above the rotor continuously sprays water to dilute and elute the slag and rinse Rotor and sieve plate. After repeated cyclic sorting, the separated good fibers are discharged from the pulp outlet under the sieve plate after passing through the sieve holes, and the peeled plastic pieces and other impurities are washed and discharged from the slag hopper and discarded as garbage.
3. The slag discharge separator is mainly composed of upper cover, rotor, sieve plate, base and transmission device.
1. The upper cover is connected to the base by a flange, and the upper cover is equipped with a water spray pipe and a slurry guide plate.
2. The rotor is a hollow shaft with a special structure, and 30 pieces can be fixed on it.
Replaced blades, and welded with axially moving blades and spirally alternately arranged cleaning plates. The sweeping blade is used to beat, tear and peel the tailings, and the sweeping plate can effectively clean the sieve plate and keep the sieve plate unblocked.
3. The sieve plate is semi-circular and made of stainless steel. The sieve plate has a variety of specifications.
The user can choose the hole according to the raw material situation and the process. The sieve plate adopts drilling, deburring, polishing and other processes to meet the technical requirements of smooth, smooth and no slurry.
4. The base is used to install the sieve plate, upper cover, rotor and other components, and the good
The pulp flows away from the pulp outlet in the base, and the separated light impurities are discharged from the slag outlet at the bottom of the base
