1. Introduction

The hydraulic screen professionally produced by Bitianyuan Company, also known as the hydraulic inclined screen, is a small non powered separation equipment used for filtering suspended solids, floating solids, sediments and other substances in sewage treatment. This equipment is generally made of stainless steel 304 material, and the screen gap can achieve various specifications such as 0.25mm, 0.5mm, 0.75mm, 1.0mm, 1.5mm, 2mm, etc. The size of the special screen gap can also be customized according to customer requirements.

2、 Scope of application

Suitable for solid-liquid separation and recovery in industrial production. Specially suitable for separating residue from bottle label paper in beer wastewater, papermaking wastewater, slaughter wastewater, juice processing wastewater, herbal tea wastewater, and plastic particle processing wastewater. The specific application scenario is used in secondary slag interception treatment, where a rotary grid is used to remove large particles of slag, which can reduce the load on the hydraulic sieve.

4、 Working principle

The main body of the hydraulic screen is a stainless steel arc-shaped or flat filtering screen made of precision wedge-shaped steel bars. The wastewater to be treated is evenly distributed on the inclined screen surface through an overflow weir. Due to the small and smooth surface gap of the screen mesh and the large back gap, the drainage is smooth and not easily blocked; Solid substances are intercepted, and filtered water flows out from the gaps of the sieve plate. At the same time, under hydraulic action, the solid substances are pushed to the lower end of the sieve plate and discharged, thus achieving the purpose of solid-liquid separation.
