Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] Such as figure 1 , figure 2 and Figure 5 Shown, a kind of pulp solid-liquid separation method for papermaking of the present invention, the method comprises the following steps:

[0032] S1: Put a large number of steel wool balls into the pulp liquid and stir for five minutes to make the solid adhere to the steel wool balls;

[0033] S2: The ice ball with a small hole is fixed at the liquid inlet of the solid-liquid separation device, and the ice ball can be filtered again, the liquid passes through preferentially, and the solid passing time is delayed;

[0034] S3: put the pulp after the agitation treatment in S1 into a solid-liquid separation device with ice balls installed at the liquid inlet, and filter;

[0035] The method uses a...

Abstract

The invention relates to the technical field of solid-liquid separation, in particular to a method for solid-liquid separation of paper pulp for papermaking. The method includes the steps of putting alarge quantity of steel balls into a pulp liquid, stirring for five minutes, wherein the steel balls can adhere to the paper scraps, so that the solid adheres to the steel balls, the paper scrap content in the pulp is reduced, and the steel balls can be reused. Ice balls with small holes are fixed at the liquid inlet of a solid-liquid separation device, and the ice balls carry filtration again. Before the ice balls are completely melted, the pulp can be filtered to allow the liquid to pass first, and the paper scrapes are filtered and adhered to delay the paper inflow time. When the ice ballsare melted, the paper scrapes fall into the device. The separation efficiency and the separation quality are improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a method for solid-liquid separation of pulp for papermaking. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods; it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp according to the processing method; traditional pulping refers to the use of chemical methods, mechanical methods or a combination of both The method of dissociating plant fiber raw materials into natural or bleached pulp production process; the usual process is to crush plant fiber raw materials, cook, wash, screen, bleach, purify, dry, and pass papermaking in the pulp manufacturing process. The pulp is screened with a pulp solid-liquid separation device. [0003] However, the traditional pulp solid-liquid separation device for papermaking is easy to cause filter blockage in the process of screening pul...
