The Drum filter for dewaxing oil is a piece of equipment used for medium-to-high efficiency solid-liquid separation in processing. Specifically designed for paraffin separation, oil separation, and dewaxing processes, it boasts core advantages of excellent separation performance and high automation.

Product Advantages

High dewaxing and separation efficiency: It can quickly separate paraffin crystals from oil, ensuring the purity of the oil product.

Automated operation: It minimizes manual intervention, reducing operational intensity and human-induced errors.

Low filter medium consumption: Featuring a long service life, it lowers the later-stage operation and maintenance costs.

Wide application range: It can meet the separation needs of dewaxing oils with different viscosities, and exhibits strong stability.

Components

Core Filtration Unit: Rotating drum, responsible for solid-liquid contact and separation;

Vacuum System: Vacuum pump and vacuum tank, providing the negative pressure environment required for separation;

Transmission System: Motor, reducer, and coupling, driving the rotating drum to operate stably;

Feeding & Discharging System: Feeding tank, feed liquid distributor, slag discharge device, and filtrate collection tank;

Control System: PLC control cabinet, liquid level sensor, and speed regulator, enabling automated control;

Auxiliary Unit: Cleaning device and filter medium regeneration mechanism, ensuring the continuous and efficient operation of the equipment.

Equipment Features

The rotating drum surface adopts a special filter medium, which has strong paraffin crystal retention capacity and is not prone to clogging.

It has excellent sealing performance and stable vacuum degree, ensuring consistency in separation results.

With a compact structure and small floor space, it facilitates workshop layout, installation, and commissioning.

It operates with low noise and minimal vibration, complying with environmental protection requirements for industrial production.

It is equipped with online cleaning and medium regeneration functions, eliminating the need for frequent shutdowns for maintenance.

Working Process

Feeding Stage: Dewaxing oil enters the filtration area through the feeding tank, and part of the rotating drum is submerged in the feed liquid;

Adsorption & Filtration Stage: Driven by vacuum, the oil liquid passes through the filter medium and enters the filtrate chamber, while paraffin crystals are retained on the medium surface to form a filter cake;

Filter Cake Dewatering Stage: As the rotating drum rotates, the filter cake leaves the feed liquid area, and the vacuum system continuously extracts the residual oil from the filter cake;

Slag Discharge Stage: The filter cake rotates to the slag discharge area, and the paraffin filter cake is scraped off by a scraper, completing the separation process;

Medium Regeneration Stage: The cleaning device rinses the filter medium to restore its filtration performance, allowing it to enter the next cycle.

Application Fields

Core Applications: Paraffin separation, oil separation processes, and dewaxing processes (e.g., mineral oil dewaxing, vegetable oil dewaxing, lubricating oil dewaxing, etc.).

Extended Applications: Separation of low-temperature crystals in various oil and fat industries, and solid-liquid separation processes for high-viscosity oils.
