Automatic Candle Filter – Intelligent Filtration & Hassle – Free Operation

The automatic candle filter combines advanced filtration technology with intelligent automation, offering efficient and continuous solid – liquid separation solutions. Engineered for high – performance and reliability, it is the ideal choice for diverse industrial applications where precision and uninterrupted operation are crucial.

I. Product Introduction

The automatic candle filter is a state – of – the – art filtration equipment designed to separate solids from liquids with high efficiency. Its core component is a set of cylindrical “candle” – shaped filter elements, typically made of high – quality stainless steel, sintered metal, or high – performance filter cloth. These filter elements are vertically installed in a pressure – resistant vessel. When the fluid mixture enters the filter, the liquid passes through the pores of the filter elements while the solids are retained on the surface, achieving solid – liquid separation. With an integrated automatic control system, the filter can complete processes such as filtration, cake formation, backwashing, and cake discharge automatically, reducing manual intervention and improving operational efficiency. This makes it widely applicable in industries like chemical, pharmaceutical, food, and environmental protection.

II. Working Process

1. Filtration Phase

   • Fluid Inflow: The fluid to be filtered, a mixture of liquid and solid particles, enters the filter vessel through the inlet. Driven by pressure (either from a pump or gravity, depending on the system design), the fluid uniformly distributes around the outer surfaces of the filter elements.

   • Solid – Liquid Separation: As the fluid permeates from the outside to the inside of the filter elements, the porous structure of the elements acts as a barrier. Solid particles larger than the pore size are retained on the outer surfaces of the filter elements, gradually forming a filter cake. Meanwhile, the clarified liquid passes through the elements and collects at the bottom of the vessel, then flows out through the outlet for subsequent use or processing.

2. Cake Formation and Monitoring

   • Continuous Filtration: As the filtration continues, the filter cake on the surface of the filter elements gradually thickens. During this process, sensors within the filter continuously monitor parameters such as differential pressure across the filter elements and the level of the liquid in the vessel. These real – time monitoring data are crucial for determining the appropriate time to start the cleaning process.

3. Self – Cleaning Trigger

   • Differential Pressure Trigger: When the filter cake reaches a certain thickness, it increases the resistance to fluid flow, causing the differential pressure between the inlet and outlet of the filter to rise. Once this differential pressure reaches a pre – set value (usually 0.3 – 0.5 MPa, depending on the application and filter design), it signals the start of the self – cleaning process.

   • Time – Based Trigger: In addition to the differential pressure, the filter can also be set to initiate cleaning based on a pre – determined operation time. For example, in applications with relatively stable fluid properties, the filter may start the cleaning process every 8 – 24 hours to ensure consistent filtration performance.

   • Production Water Filtration: Purifies production water by removing suspended solids, microorganisms, and organic impurities, ensuring the safety and hygiene of food and beverage products.

   • Product Filtration: Filters beverages (such as juice, beer, and wine), edible oils, and other food products to improve clarity, remove sediment, and enhance product quality and shelf – life

VI. FAQ

1. How long does the filter element of the automatic candle filter last?
   The service life of the filter element depends on various factors, including the nature of the fluid being filtered, filtration precision, and operating conditions. Under normal circumstances, stainless – steel wire mesh elements can last 1 – 3 years, while sintered metal or filter cloth elements may last 0.5 – 2 years. Regular maintenance and proper operation can extend the service life of the elements.

2. Can the automatic candle filter handle highly viscous fluids?
   Yes, the filter can be customized to handle highly viscous fluids. By adjusting parameters such as filtration pressure, filter element material, and pore size, as well as using appropriate pre – treatment methods, the filter can achieve effective solid – liquid separation for viscous fluids. However, it is recommended to consult our technical team for specific customization solutions.
