Application Areas
1. Livestock manure treatment: solids are composted to produce fertilizer, and liquids are used to generate biogas or are reused.
2. Organic fertilizer pretreatment: reducing the moisture content of raw materials to 65%-75% to facilitate composting and fermentation.
3. Wastewater pretreatment: separating suspended solids from industrial/slaughterhouse wastewater to reduce the subsequent treatment load.
4. Food waste treatment: separating liquid and waste to reduce transportation and handling costs.
Working principle of Inclined screen solid-iquid separator:
1. Pre-screening: The material (85%-98% moisture content) is conveyed to a 15°-30° inclined screen. The liquid passes through the 0.5-2mm mesh by gravity, initially separating 30%-50% of the water and intercepting the solids.
2. Extrusion Dehydration: After pre-screening, the solids slide into an extrusion mechanism (screw/roller type). A variable-pitch auger or pressure rollers are applied to reduce the moisture content to 60%-80%.
3. Solid-Liquid Separation: The separated liquid is combined and discharged (to a biogas digester/wastewater treatment plant), while the solids are discharged through the outlet and directly used as organic fertilizer raw material.
Advantages of Inclined screen solid-iquid separator:
1. High Efficiency and High Capacity:
The combined process (pre-screening + extrusion) provides high separation efficiency and high production capacity, making it suitable for large-scale production.
2. Anti-clogging and Easy Maintenance:
The inclined screen surface and high-pressure cleaning prevent clogging with coarse fibers. Removable wearing parts require only daily cleaning and inspection, eliminating the need for specialized personnel.
3. Low Energy Consumption and Economical:
The low-power motor and stainless steel screen have a lifespan of 1-2 years, resulting in low long-term operating costs.
4. Widely Compatible:
It can process manure, biogas residue, and food waste, eliminating the need for complex pretreatment.
5. Convenient Operation:
The PLC control supports semi-automatic and fully automatic operation, and the liquid level sensor automatically adjusts parameters, minimizing manual intervention.

What industries and materials is the inclined screen solid-liquid separator primarily suitable for?
Due to its efficient separation properties, the inclined screen solid-liquid separator is widely used in livestock farming, slaughtering and processing, food processing, printing and dyeing, chemical industry, municipal wastewater, aquaculture, and other fields. Specific suitable materials include: farm manure (pig manure, cow manure, chicken manure, etc.), a mixture of blood and meat residue from slaughterhouses, fruit and vegetable juice extraction residue from food factories, printing and dyeing wastewater scum, solid-containing wastewater from the chemical industry, and screen residue from municipal wastewater pretreatment. It is particularly suitable for treating suspended materials with a solids content of 1%-15% and a particle size ≥0.1mm.
What is the device's solid-liquid separation efficiency? What is the approximate moisture content of the solid residue and liquid after separation?
Under normal operating conditions, the inclined screen solid-liquid separator can achieve a solid-liquid separation efficiency of 85%-95% (depending on material characteristics and equipment parameters). After separation, the moisture content of the solid residue is typically controlled at 65%-80%, resulting in a loose, loose solids that can be directly used for composting, organic fertilizer production, or incineration. The solids content of the separated liquid can be reduced to below 1%, reducing the load on subsequent wastewater treatment systems (such as biogas tanks and aeration tanks) and improving overall treatment efficiency.
How should the equipment's processing capacity be selected? What factors should be considered when determining the model?
The processing capacity should be determined based on three key factors: the average daily total volume of solid-liquid mixture in actual production, the maximum hourly processing peak, and the solids concentration of the material. Common equipment capacities range from 1-5 m³/h (small) to 50-100 m³/h (large). Varies. When selecting a model, you should also consider: the hardness of the solid particles in the material, their corrosiveness, the presence of fibrous impurities, and the separation requirements of subsequent processing steps (such as the moisture content of the solid residue and the clarity of the liquid).
Is the screen a consumable part? What is its service life? Is it easy to replace?
The screen is the core consumable component of an inclined screen solid-liquid separator. Its service life is directly related to the material characteristics, frequency of use, and maintenance methods. For low-hardness materials such as livestock manure, a standard stainless steel screen (pore size 0.3-1mm) has a service life of approximately 3-6 months. For materials containing hard particles (such as sand and gravel), a wear-resistant alloy screen should be selected, extending its service life to 6-12 months.
The equipment is typically designed with a "quick-release screen structure." Replacement requires no disassembly of the entire machine; simply loosen the bolts on both sides, remove the old screen, and replace it with a new one. This can be completed by one person in 15-30 minutes, making it highly convenient for maintenance.
