The screw press dehydrator is an important equipment widely used in agriculture, food processing, environmental protection and other fields. Its main function is to separate liquid from solid matter to achieve the purpose of dehydration. This article will introduce the structural components of the screw press dewatering machine in detail to help readers better understand this important equipment.

1. Main structure

1.1. Frame: The frame of the screw press dehydrator is the supporting structure of the entire equipment. It is usually made of steel and has sufficient strength and stability to withstand various forces and vibrations during work.

1.2. Screw shaft: The screw shaft is the core component of the screw press dehydrator and one of its main working parts. The spiral shaft is usually made of high-strength stainless steel and has a spiral shape. It is responsible for transporting the dewatered material from the feed port to the discharge port and applying pressure during the process to achieve the dehydration effect.

1.3. Screen: The screen of the screw press dehydrator is located outside the screw shaft and is used to separate solid materials from liquids. The pore size and shape of the screen can be adjusted according to different materials and dehydration requirements.

1.4. Electric motor: The electric motor is the power source of the screw press dehydrator. It is usually installed on the frame and connected to the screw shaft through a belt or chain, providing rotational power to drive the operation of the screw shaft.

1.5. Discharge port: The discharge port of the screw press dehydrator is located at the bottom of the frame. It is used to discharge dehydrated solid materials. It is usually equipped with a valve or gate to control the discharge speed of the material.

2. Feeding system

2.1. Feed port: The feed port is the entrance where materials to be dehydrated are introduced into the screw press dehydrator. It is usually located on the top or side of the equipment. Materials can be put in manually or automatically.

2.2. Feeding and conveying device: In order to ensure that materials can enter the screw press dehydrator smoothly, it is usually necessary to equip a feeding and conveying device, such as conveyor belts, screw conveyors, etc., to provide uniform material supply.

3. Liquid discharge system

3.1. Liquid discharge port: The liquid discharge port of the screw press dehydrator is located at the bottom or side of the equipment. It is used to discharge the separated liquid part. It is usually equipped with a valve or pump to control the discharge of liquid.

3.2. Liquid collection device: The separated liquid usually needs to be processed or recycled, so a liquid collection device, such as a liquid storage tank, piping system, etc., needs to be set up to export the liquid or further process it.

4. Control system

4.1. Control panel: Screw press dehydrators are usually equipped with electrical control systems, including control panels, buttons, switches, etc., which are used to start, stop and adjust the operation of the equipment, as well as monitor various parameters.

4.2. Sensors and instruments: In order to monitor and control the operating status of the screw press dehydrator, temperature sensors, pressure sensors, liquid level meters and other sensing devices are usually installed to ensure the safe and stable operation of the equipment.

5. Accessories and auxiliary equipment

5.1. Cleaning device: In order to avoid the accumulation of dirt and residue during the use of the equipment, a cleaning device is usually required for regular cleaning of the spiral shaft and screen.

5.2. Safety protection devices: Screw press dewatering machines are usually equipped with various safety protection devices, such as emergency stop devices, overload protection devices, etc., to ensure the safety of operators and the reliability of equipment.

Summarize:

The screw press dehydrator is an important separation equipment. Its structure includes the main structure, feeding system, liquid discharge system, control system, accessories and auxiliary equipment. By rationally designing and configuring these components, the screw press dehydrator can efficiently complete solid-liquid separation and is widely used in various industrial fields to improve production efficiency and resource utilization. I hope this article can help readers better understand the structure and working principle of the screw press dehydrator.
