Candle filter is a kind of automatic filter equipment. Candle filter is a filter that uses the filter cartridge as the skeleton. The filter medium are the filter cloth and filter cake layers that covering the filter cartridge, and uses pump pressure to achieve liquid clarification.
Candle filter can choose different filter materials according to the filter medium, filter precision, filter residue viscosity and so on.
When the slurry is pressed into the pressure vessel, the direction of the slurry is always from the bottom up. It is conducive to the solid particles settling on the surface of the filter candle in the uniform suspension to ensure the formation of a consistent filter cake.
Filter cakes form on the outer surface of each stainless steel candle filter element. According to the design requirements, the filter candles in each row are connected to the top in series connection and parallel connection. This design is determined according to the result of the process requirement.
The discharge pipe for the slurry is linked to the level set, and every set tube is attached to the primary branch line via the electric valve. The electronic valves control the filtration and reverse wash, and each valve optimizes the formation of the filter cake of the filter candles online by controlling the flow. All header slurries are transported to the main branch line by electric control to form a loop filtering process.

- Fully closed solid-liquid separation system, the whole process (filtration, washing, drying, slag discharge) is carried out in a closed container, which shortens the process flow, reduces the labors. It has no leakage and no environmental pollution
- The solid-liquid separation system that truly achieves dry and wet separation ensures the filtration accuracy of the clear liquid, and at the same time, it can automatically discharge the solid in the form of dry filter cake, avoiding the process of cleaning the filter element of the traditional filter.
- PLC automatic control, the operation of the whole system is highly automated. Compared with traditional filter presses, closed plate type, suction filter cylinders, etc., it not only saves a lot of labor costs and time costs, but also better maintains the continuity of enterprise production.
- The solid-liquid separation system with automatic cleaning and automatic regeneration, and the repeated use of filter media, solves the problem that traditional filters need to be replaced and deal with a large number of consumables.
- The solid-liquid separation system that can achieve sub-micron filtration accuracy solves the problems of leakage and incomplete filtration of traditional filtration and separation equipment when dealing with materials with large solid content.
- The main body is a static part, with dynamic backflushing, low failure rate and low operating cost.
- Filter element grouping design reduces backflushing air consumption and isolates damaged filter elements.
- Candle filtration has gradually replaced filter press and bag filtration as the mainstream filtration method, which not only maintains the continuity of enterprise production, but also greatly reduces the risk of production accidents while improving production efficiency and saving labor.
