preparation example Construction

[0029] A novel clarification tank preparation method in the present invention. mainly includes:

[0030] A. FRP production of inner and outer molds: Weigh the resin, accelerator and diluent for inner mold felting, add to the stirring tank and stir evenly; weigh the resin, accelerator and diluent for outer mold felting, add to the stirring tank Inner and stir evenly; cut 450G glass fiber chopped strand mat; spread a layer of chopped strand mat on the mold, add curing agent (1% to 4%) to the ready-to-use inner mold resin or outer mold resin, and stir evenly , use a special roller to soak the chopped strand felt, roll it hard, and then use a special air bubble to drive away the air bubbles until there are no air bubbles and no empty drums;

[0031] B. Make reinforced steel mesh, and use steel wires for "X" binding at the intersection of the steel mesh, also known as "ten" binding;

[0032] C. Prepare casting sand: prepare quartz sand in proportion for use;

[0033] D. Prepare ...

Embodiment 1

[0041] Production of FRP for the inner mold: Weigh the resin, accelerator and diluent for the inner mold felt, the ratio of resin, accelerator and diluent is 96:3.5:0.5 parts by weight, add it to the stirring tank and stir evenly; cut 450G glass fiber short Cut felt: spread a layer of chopped strand felt on the mold, add 1 part of curing agent to the ready-to-use internal mold resin, stir evenly, soak the chopped strand felt with a special roller, roll it hard, and then use a special air bubble Drive away the air bubbles until there are no air bubbles and no empty drums to get the inner mold; during the production process, no resin can hang or flow off the ground.

[0042] Production of FRP for the outer mold: Weigh the resin, accelerator and diluent for felting the outer mold, the ratio of resin, accelerator and diluent is 96:3.5:0.5 parts by weight, add it to the stirring tank and stir evenly; cut 450G glass fiber short Cut felt: spread a layer of chopped strand felt on the ...

Embodiment 2

[0044]Production of FRP for the inner mold: Weigh the resin, accelerator and diluent for the inner mold felt, the ratio of resin, accelerator and diluent is 96:3.5:0.5 parts by weight, add it to the stirring tank and stir evenly; cut 450G glass fiber short Cut felt: spread a layer of chopped strand felt on the mold, add 2 parts of curing agent to the ready-to-use internal mold resin, stir evenly, soak the chopped strand felt with a special roller, roll it hard, and then use a special air bubble Drive away the air bubbles until there are no air bubbles and no empty drums to get the inner mold; during the production process, no resin can hang or flow off the ground.

[0045] Production of FRP for the outer mold: Weigh the resin, accelerator and diluent for felting the outer mold, the ratio of resin, accelerator and diluent is 96:3.5:0.5 parts by weight, add it to the stirring tank and stir evenly; cut 450G glass fiber short Cut felt: spread a layer of chopped strand felt on the ...

Abstract

The invention discloses a novel clarification tank, comprising a skeleton part, quartz sand and a resin mixture, wherein the quartz sand is one or more selected from the group consisting of quartz sand with a size of 10-20 meshes, quartz sand with a size of 21-80 meshes, quartz sand with a size of 81-150 meshes, quartz sand with a size of 151-250 meshes, and quartz sand with a size of 201-300 meshes, and the resin mixture comprises one or more selected from the group consisting of resin, a surfactant, a diluent, an accelerant and an antifoaming agent. According to the clarification tank of theinvention, the wall of the clarification tank has a skeleton portion which can support the entire clarification tank and improve the pressure resistance and impact resistance of the tank body; the quartz sand with different meshes is cooperatively used with the resin mixture, thereby ensuring that the clarification tank has good compressive strength and bending resistance and a small coefficientof thermal expansion, so the service life of the clarification tank is greatly prolonged; in addition, the surface of the clarification tank is enhanced in corrosion resistance and wear resistance.

Description

technical field [0001] The invention relates to the field of clarification tank processing, in particular to a novel clarification tank and a preparation method thereof. Background technique [0002] The mixing and settling tank is the first step-by-step contact extraction equipment used by people. The two immiscible liquid phases in each level of equipment will undergo two processes of stirring, mixing and clarifying phase separation, so as to achieve the target solute in different liquid phases. mass transfer and separation. [0003] The clarifier can be operated in a single stage, or in series or in parallel with multiple stages. In order to increase the contact area between the two phases and strengthen the turbulent movement, a stirrer is often installed in the tank, and a pulse or injector can also be used to achieve sufficient mixing of the two phases. The function of the clarifier is to separate the extract phase and the raffinate phase that are close to the equili...
