Why choose Yinuo Vacuum rotary drum filter?

In the selection of industrial filtration equipment, Yinuo vacuum rotary drum filter has become the preferred choice for many enterprises due to its three core advantages of technical adaptability, operational stability, and cost-effectiveness.

1.Efficient adaptation to multiple working conditions: Whether it is fine particle suspensions or high viscosity colloids, various slurries can be handled. Adjusting the filter cloth, drum speed, and vacuum degree according to the situation of the slurry can achieve an efficiency of over 90% in solid-liquid separation, solving the problem of incomplete separation in traditional equipment.

2. Automated cost reduction and efficiency improvement: It comes with automatic feeding, unloading, and filter cloth cleaning functions, eliminating the need for frequent manual labor. Compared to manual equipment, it can save more than 60% of labor costs and avoid fluctuations in filtration efficiency caused by differences in manual operation.

3. Stable operation and low maintenance cost: The core components of the drum and vacuum system are made of wear-resistant and corrosion-resistant materials, such as 304/316 stainless steel and silicon carbide coating, which can operate stably for an average of more than 8000 hours. Fragile parts such as filter cloth and sealing gasket are also easy to replace, and can be understood within 1 hour of a single maintenance.

4. Low energy consumption, in line with environmental requirements: The vacuum pipeline has been optimized and equipped with energy-saving vacuum pumps. The energy consumption per unit filtration area is 15% -20% lower than the industry average. In addition, it can achieve dry discharge of filter residue and recovery and reuse of filtrate, meeting the needs of environmental emissions and resource recycling.

5. Strong customization ability: able to customize equipment with special materials or scraper/spiral discharge and heating jacket according to user needs, such as the corrosiveness, temperature, solid content of the slurry, and production capacity requirements of 0.5-50 square meters of filtration area, covering multiple industry segmentation needs.

Working Principle

The Yinuo Vacuum rotary drum filter, based on the principle of "vacuum suction filtration", achieves fully automatic continuous solid-liquid separation by rotating the drum clockwise

Feed infiltration stage (0 ° -30 °)

The lower part of the drum is immersed in the feed slurry, and the liquid is vacuum sucked away. The solid remains on the filter cloth to form an initial filter cake, and stirring can be selected to prevent particles from settling to the bottom.

Suction filtration stage (30 ° -150 °)

The drum with filter cake leaves the slurry, and vacuum continues to filter, increasing the thickness of the filter cake to 5-30mm. The filtrate is distributed through a distribution head and vacuum tube, and then transported to the subsequent processing stage by a centrifugal pump.

Drying stage of filter cake (150 ° -210 °)

Continuous vacuum action reduces the moisture content of the filter cake to 10% -30%.

Blowing loosening stage (210 ° -240 °)

The distribution head is switched to blowing mode, and compressed air is blown in reverse from the drum, allowing the filter cake to detach from the filter cloth for easy unloading.

Unloading stage: (240 ° 300 °)

The drum rotates to the unloading area, and the scraper scrapes off the filter cake, which falls into the conveyor belt or collection tank for recycling.

Filter cloth cleaning stage (300 ° -360 °)

Spray clean water to wash away residual particles in the filter cloth, restore filtration performance, and the cleaning wastewater can be recycled and reused.

By completing the above 6 stages and continuously cycling, the vacuum rotary drum filter can achieve fully automatic operation of "feeding filtration drying unloading washing" without stopping the machine.

Core functions

1. Efficient solid-liquid separation: It can quickly separate solids and liquids in the suspension, producing a filter cake with adjustable moisture content and clarified filtrate, meeting the needs of subsequent filter cake recovery/treatment and filtrate circulation/discharge.

2. Process adaptation function: adjustable drum speed, vacuum degree, feed rate, suitable for filtering different materials, and can also customize heating and insulation to deal with high temperature slurry or easily solidified materials such as grease, paraffin, etc. at ≤ 150 ℃, avoiding agglomeration.

3. Operation monitoring and protection: Real time monitoring of vacuum degree, filtrate flow rate, and filter cloth cleaning pressure. Abnormal parameters will automatically alarm and trigger protection mechanisms; Equipped with a "filter cloth deviation detection" device to prevent the filter cloth from deviating during operation and avoid a decrease in filtration efficiency.

4. Convenient maintenance function: The filter cloth adopts a quick replacement structure, fixed by buckles or bolts, and can be changed within 30 minutes by a single person. The drum and distribution head are designed with a "removable and washable structure", which can be easily disassembled during regular maintenance to remove residual materials and prevent corrosion.

Product Features

Compared with traditional vacuum filtration equipment, the Yinuo device has six core advantages

Continuous operation is necessary for stability

the drum does not stop rotating, without the need for the short operation of "feeding filtering unloading" like a plate and frame machine. A single unit can process 0.5-30m ³ per hour

Slurry, suitable for large-scale industrial production.

Low moisture content of filter cake and good solid material quality

Through two-stage dehydration of "suction filtration+drying" and adjustable vacuum degree, the moisture content of filter cake is 5% -15% lower than traditional leaf filters, and the energy consumption of subsequent drying processes can also be reduced. For example, in the chemical industry, the steam consumption of filter cake drying can be reduced by more than 20%.

Strong corrosion resistance, capable of handling various types of materials

316L stainless steel and Hastelloy can be selected as core components, and PTFE material with acid, alkali, and high temperature resistance can be selected as filter cloth. It can handle acidic materials such as sulfuric acid and hydrochloric acid, alkaline materials such as sodium hydroxide, as well as organic solvent materials, with a wide range of adaptability.

High degree of automation and simple operation

controlled by PLC+touch screen, different material filtering parameters can be pre-set. When changing materials, only the template needs to be adjusted without repeated debugging. Remote monitoring can also be optionally installed, and the device status can be viewed on a mobile phone or computer.

Small footprint and high space utilization

The equipment is designed vertically and compactly, occupying 30% -50% less space compared to vacuum leaf filters of the same production capacity, making it suitable for situations where workshop space is limited.

Energy saving and Environmental Protection

Equipped with energy-saving vacuum pumps, the unit energy consumption is low, the filtrate can be recycled and reused, and the amount of solid waste treated by filtering biscuits is reduced, which is in line with the national policies of "energy saving and emission reduction" and "circular economy", helping enterprises reduce environmental protection costs.
