1. Overview

Jiahe Conveying Equipment Technology Co., Ltd. (hereinafter referred to as “Jiahe”) is a company specializing in the research and development, design, manufacture, and sales of spiral conveying equipment and components. Its core products include axial spiral flights, non-axial spiral flights, axial spiral bodies, non-axial spiral bodies, UPE wear-resistant liners, spiral conveyors, sand separators, spiral presses, etc. This report aims to analyze the application of Jiahe's spiral flights (screw flights) in the environmental industry, focusing on their parameters, application scenarios, and precautions, and incorporating information from the Jiahe website.

2. The Role of Spiral Flights in the Environmental Industry

In the environmental industry, spiral flights, as key components of spiral conveyors, are primarily used for the following applications:

• Sludge Conveying: Sludge produced in wastewater treatment plants and waste treatment plants is typically viscous and has a high solids content, making it prone to clogging conveyors. Spiral flights are used to transport sludge from one location to another, such as before dewatering.

• Waste Treatment: In waste sorting, pre-treatment for waste incineration, spiral flights are used to mix, transport, or sort waste.

• Biogas Production: Used for mixing and transporting sludge and other materials.

• Tailings Treatment: In mining tailings treatment, spiral flights are used to transport, mix, or dewater tailings.

• Biomass Treatment: Used to transport raw materials such as straw and wood chips.

3. Jiahe's Spiral Flight Product Features and Parameters

Jiahe offers a wide range of spiral flight products to meet the needs of various environmental industries. Key features are as follows:

• Variety of Materials: Provides a variety of materials including stainless steel (304, 316L), carbon steel, cast steel, and manganese steel to adapt to the corrosion and abrasion resistance of different materials.

• Flexible Structure: Provides axial spiral flights and non-axial spiral flights, the former suitable for short-distance transport, and the latter for long-distance transport.

• Customized Design: Can be customized according to customer's specific needs, including flight shape, size, thickness, and material.

• Special Processes: Employs special processes such as plasma strengthening, precision casting, and cold rolling to improve flight wear resistance, corrosion resistance, and strength.

4. Application Scenarios and Precautions

4.1 Sludge Conveying

• Scenario: Wastewater treatment plants, waste treatment plants, pre-treatment before sludge dewatering.

• Precautions:

• High sludge solids content, choose wear-resistant materials such as manganese steel or high manganese steel, or use plasma strengthening processes to improve wear resistance.

• Flight shape design should avoid blockage, tapered and shaped flights are good choices.

• Pay attention to the gap between the flight and the pipe to prevent leakage.

• Regularly check the wear condition of the flight and replace it in a timely manner.

4.2 Waste Treatment

• Scenario: Waste sorting, pre-treatment for waste incineration.

• Precautions:

• Waste is complex, choose corrosion-resistant materials such as 316L stainless steel.

• Pay attention to the damage of sharp objects in waste to the flight, consider increasing flight thickness or adopting special protection measures.

• Regularly clean waste residue from the flight.

4.3 Biogas Production

• Scenario: Mixing and transporting sludge and other materials.

• Precautions:

• There may be corrosive gases during biogas production, choose corrosion-resistant materials.

• Sludge is abrasive, choose wear-resistant materials.

4.4 Tailings Treatment

• Scenario: Transporting, mixing, and dewatering tailings.

• Precautions:

• Tailings contain abrasive particles, choose wear-resistant materials.

• Pay attention to the corrosion of impurities in tailings.
