1. Introduction

Screw presses and screw dewatering machines are core product lines for Jiahe Conveying Equipment Technology Co., Ltd., widely applied in municipal sewage treatment, industrial wastewater treatment, agricultural waste treatment, and various other fields. This report aims to provide a comprehensive selection guide for Jiahe’s sales and technical teams, assisting customers in choosing the most suitable screw dewatering equipment for their needs. The report will detail the characteristics, application scope, and technical parameters of different models, and provide selection recommendations.

2. Product Overview

• Screw Press: Utilizes a rotating screw shaft to compress the material, separating solids and liquids through a screen. Simple structure, easy maintenance, and low operating costs.

• Screw Dewatering Machine (Sludge Dewatering Machine): Similar to a screw press, but typically possesses greater compression capabilities and finer screens, suitable for materials with higher solids content.

3. Model Specifications & Technical Parameters

• Screw Flight Design: Jiahe can customize screw flights based on material properties, including flight shape, spacing, and material. Common flight types include:

• Standard: Suitable for general materials.

• Scraper: Suitable for viscous materials, preventing material adhesion.

• Cutting: Suitable for fibrous materials, preventing entanglement.

• Material Selection: Stainless Steel 304, 316L, Carbon Steel, etc. Select based on corrosive environment.

• Drive Method: Direct motor drive, gear reducer drive.

4. Application Scenarios & Target Customers

• Municipal Sewage Treatment Plants: Sludge dewatering, reducing treatment volume, lowering transportation costs.

• Industrial Wastewater Treatment Plants: Wastewater treatment for chemical, food, paper, and pharmaceutical industries, recycling water resources.

• **Agricultural Waste Treatment:**沼气池 sludge, livestock wastewater treatment.

• Small Environmental Stations: Distributed wastewater treatment, meeting local environmental requirements.

• Target Customers: Municipal engineering construction units, environmental engineering companies, industrial enterprises, agricultural production enterprises.

5. Selection Recommendations

• Material Properties: Consider material solids content, viscosity, particle size, corrosiveness, etc.

• Processing Capacity: Determine processing capacity based on actual needs.

• Dewatering Requirements: Determine dewatered solids content based on downstream processing requirements.

• Site Conditions: Consider equipment installation space and power conditions.

• Economic Benefits: Consider equipment cost, operating cost, and benefits comprehensively.

6. Maintenance & Care

• Regularly clean the screen to prevent clogging.

• Regularly lubricate the gear reducer to extend service life.

• Regularly inspect the screw flights to prevent wear.

• Regularly inspect the motor to prevent overheating.

7. Conclusion

Jiahe’s screw presses and screw dewatering machines are efficient, energy-saving, and environmentally friendly solid-liquid separation equipment. Through reasonable selection and maintenance, customers can achieve significant economic and social benefits.
