As a type of washing equipment, the dewatering screen is mainly used for solid-liquid separation, especially playing a key role in the washing process. The following is a detailed introduction to the dewatering screen:
1. Working principle of the dewatering screen:
• Material feeding: The material to be processed (such as suspension, slurry, or suspended solid particles) enters the screen surface of the dewatering screen through the feed port.
• Vibration: The dewatering screen vibrates the screen surface through a vibration mechanism (such as a vibration motor). The frequency and amplitude of the vibration can be adjusted to adapt to different particle sizes and material characteristics.
• Filtration: Under the action of vibration, the material forms a layer of particle accumulation on the screen surface. Larger particles are blocked above the screen surface to form a slurry layer, while smaller particles and liquids enter the bottom of the screen through the screen holes.
• Drainage: Water is gradually discharged through the filter medium (such as a fine screen or filter cloth) on the screen surface to achieve a dehydration effect.
• Solid-liquid separation: Solid particles gradually deposit on the top of the screen hole to form a slurry layer as the material moves, and the water is discharged after being dehydrated by the filter medium, and finally solid-liquid separation is achieved.
2. Performance advantages of dewatering screen:
• Reliable operation and easy maintenance: The unique exciter makes the running track more stable and reliable, easy to install and debug, and easy to operate and maintain.
• Compact structure and high rigidity and strength: The steel components are riveted and welded to form a high-strength, stress-free, light, and durable frame body with compact structure, high rigidity, and strength of each part.
• Easy replacement and good dehydration effect: The vibration is electrically operated and easy to replace. Rubber springs are used to reduce the vibration of the base so that the amplitude is not large, and slow vibration can be clean.
• Customizable and firm equipment: It can be customized according to the water content and output. The side panels of the machine body have reinforcement plates, the bottom is equipped with brackets, and there are horizontal bars. The discharge port is supported by a triangular steel plate.
• Wear-resistant parts are used for long service life: The vibration motor uses high-strength bolts, and high-wear-resistant screen plates, and the bottom springs are rubber springs. The screen plate is fixed with high density and reinforcing ribs are punched in the screen plate.
• Adjustable sieve holes, low noise: The sieve holes of the dewatering screen can be adjusted according to needs, the whole equipment has low noise and a good dewatering effect.
3. Application scenarios of the dewatering screen:
Dewatering screen is mainly used in tailings dry discharge of ore dressing plants, sand washing in sand and gravel plants, coal slime recovery in coal preparation plants, etc. It is also widely used in various washing processes, such as hotel washing equipment, water washing plastic dehydration, etc.
