Material settling tank

—The density-sorting "smart pool" uses hydraulic differences to purify and recycle materials.

Core positioning:The sinking and floating washing tank is used in plastic crushing and washing lines.Sorting and primary cleaning based on density differencesThe core equipment utilizes the buoyancy and sinking properties of different plastics and impurities in liquids with specific specific gravities (usually water) to achieve [the following].Separation of light and heavy materials (such as PE/PP and PET/PVC), and thorough removal of heavy impurities such as sand and metal.This lays a pure foundation for subsequent fine cleaning and granulation.

I. The Core Role of the Floating/Sinking Tank in the Crushing and Washing Line

In plastic recycling, sorting the mixture is the first step in improving quality and efficiency, and the flotation tank plays the role of "referee" in this process:

1. Density sorting (core function):

   • Separate light and heavy materials:Plastics with a density less than water (such as...)PE、PPPlastics that float on water and have a density greater than water (such as...)PET, PVC, PSSinking to the bottom of the water, achievingAutomated separation of material categories。

   • Remove heavy impurities:makemud, sand, stones, glass, metal shavingsImpurities of equal weight sink into a special structure at the bottom and are separated and discharged.

2. Primary cleaning and friction:Through the turbulence of the water and the friction between the materials, most of the material is peeled off and washed away.Adhesive dirt, labels, dust。

3. Buffering and homogenization:As a buffer unit connecting crushing and subsequent friction cleaning, it can adjust the material flow rate and ensure stable operation of the production line.

A lack of or poorly designed flotation tanks can lead to:

• Cross-contamination of materialsRecycled materials have low purityIts value is greatly reduced.

• Heavy impurities are then introduced into subsequent processes.Increased wear and tear on equipment (such as friction machines and screws).。

• Inadequate cleaning results increase the burden on subsequent processes.

II. Core Product Design and Technological Advantages

We adopt"Scientific flow channel design + multi-stage sorting enhancement + intelligent sewage discharge"The systematic design concept enables efficient separation and stable operation.

1. Optimized tank structure and flow field design:

• Stepped/multi-compartment design:The tank is divided intoFeed pre-washing zone, main separation zone, and clear water overflow zoneWith multiple functional areas, the water flow path is scientifically designed, resulting in more thorough separation.

• Customized water flow system:

  • Bottom aeration device:Generate by controlled compressed air
