Inclined screen solid-liquid separator

How does an inclined screen solid-liquid separator work?

The machine uses a precisely angled, wedge-wire screen. Wet slurry is pumped to the top of the screen and flows down. Gravity pulls the liquid through the screen’s small gaps, while the solid materials slide off the surface at the bottom.

The design of the Slope Screen Separator is brilliant in its simplicity. We have engineered it to make the most of a basic law of physics. Think of it like a perfectly designed, industrial-strength kitchen strainer.

Feeding the Slurry: First, liquid manure slurry is pumped from your pit or tank to an inlet box at the very top of the sloped screen. This is the only part of the process that requires a pump.
Flowing Over the Screen: The slurry then overflows from the inlet box and begins to flow evenly down the surface of the screen. The screen itself is the heart of the machine. It is not just a simple mesh; it is made from special “wedge wire.”
The Magic of Wedge Wire: The wires have a unique V-shape. This shape creates a very thin opening on the top surface but a wider gap underneath. This design is very important. It allows water to pass through easily, but it is highly resistant to clogging because any particle that fits through the top opening will not get stuck.
Separation in Action: As the slurry flows down, gravity pulls the liquid straight down through the wedge wire screen. This separated liquid is collected in a tank below. The solid fibers, however, cannot pass through. They continue to slide down the angled surface of the screen and fall off the end, forming a pile of dewatered solids.

Characteristics of solid liquid separator machine

Circular filter screen

Efficient screening capability: The inclined screen solid-liquid separator adopts high-frequency vibration or extrusion technology, which can quickly separate solid particles and improve screening efficiency.
Wide application scope: This device is suitable for various solid-liquid separation scenarios, including mining, chemical, environmental protection, food, pharmaceutical and other industries, as well as livestock manure treatment in breeding farms, dehydration of fertilizer raw materials in organic fertilizer manufacturing enterprises, etc.
Simple and reliable structure: The inclined screen solid-liquid separator has a simple structure, is easy to install and maintain, and has high working stability.

Low energy consumption and high efficiency: Advanced vibration or extrusion technology is adopted, which can reduce energy consumption and improve economic benefits while ensuring screening efficiency.
High processing capacity: The equipment has a large processing capacity, which can meet the needs of large-scale production.
Less solid loss: After separation, the solid content in the wastewater is extremely low, which is beneficial for subsequent treatment.

The function of vibration screening

Vibration force drive: The inclined screen solid-liquid separator generates vibration force through a vibration device, causing relative motion between the sieve and the material on it.
Material movement: Under the action of vibration force, the mixture (solid particles and liquid) moves along the inclined surface of the inclined screen. Solid particles jump and roll on the sieve due to the action of vibration force, thereby increasing the chance of contact with the sieve.
Screening process: As the material moves, smaller solid particles will enter the lower layer or flow out of the equipment through the sieve holes, while larger solid particles will be left above the sieve because they cannot pass through the sieve holes, thus achieving preliminary separation of solids and liquids.

What Are Its Biggest Practical Advantages?

The main advantages are zero electricity costs for operation, almost no maintenance, and a very low initial investment because of its simple, non-mechanical design. It is the most economical separation method available.

For a B2B customer focused on the bottom line, the benefits of a Slope Screen Separator are clear and compelling. It is a machine that saves you money every single day.

The simplicity of this machine is its greatest strength. You install it, and it just works. There are no operator controls to worry about, no motors to service, and no complex parts to order. It is the definition of a “set it and forget it” solution, which is exactly what you need for a busy farming operation that is the first step of a complete fertilizer production line.

Application scope of Inclined sieve solid liquid separator

Breeding industry: used for dry wet separation of animal manure such as pigs, cows, and chickens, separating manure into liquid organic fertilizer and solid organic fertilizer.
Organic fertilizer manufacturing: Dehydration equipment used as fertilizer raw materials to improve the quality of organic fertilizers.
Environmental protection industry: used for environmental protection projects such as wastewater treatment and sludge dewatering.
Food industry: dehydration and separation of distiller’s grains, beer lees, sweet potato residues, cassava residues, various fruit residues, medicinal residues, alcohol residues, brewery vinegar residues, and soy sauce residues.
Other industries: such as pulp dewatering in paper mills, solid-liquid separation of slaughterhouse wastewater, and wastewater treatment in artificial board factories.

Frequently Asked Questions (FAQ)

Question 1: How dry will the separated solids be?
The solids from a slope screen will not be as dry as those from a mechanical press. You can expect a moisture content of around 60-70%. It will be a wet, fibrous material, not a “stackable” solid. Its main job is to remove the bulk liquid easily and cheaply.

Question 2: What is the screen made of, and will it last?
We construct the screens from high-quality 304 or 316 stainless steel. This material is extremely strong and highly resistant to the corrosion that manure can cause. A wedge wire screen is incredibly durable and will provide many years of service with no issues.

Question 3: Does it work for thick, heavy manure?
This machine works best with slurry that has a high liquid content and can flow easily. It is ideal for flushed manure systems found in dairy or pig operations. It is not designed for very thick, paste-like manure, which will not flow down the screen properly.

Question 4: What kind of maintenance is required?
Maintenance is almost zero. Because there are no moving parts, there is nothing to lubricate or repair. We recommend a simple periodic rinse with a hose to wash off any buildup and keep the screen surface clean. This takes only a few minutes.

What are the types of Solid Liquid Separator

There are various types of solid-liquid separators, including spiral extrusion separators, inclined screen separators, and stacked screw separators, each with their own characteristics and applicable ranges. When choosing, it should be comprehensively considered based on actual needs, wastewater characteristics, and treatment requirements.
