There is a possibility of filter blockage in the decanter centrifuge.
Filter blockage is mainly caused by the following factors:
1. Material particles are too large: easy to block the filter mesh.
2. Improper speed setting: Too low speed will affect the separation effect and aggravate the blockage.
3. Lack of equipment maintenance: Long-term non-cleaning and maintenance will lead to accumulation of debris.
4. Improper flow control: Too large or too small flow may cause blockage.
When the decanter centrifuge is difficult to start, the filter may be clogged. This is because there are too many residual items in the drum and the spiral filter holes are clogged. When the filter is clogged, you can adjust the speed and flow rate according to the operating conditions, establish a regular maintenance mechanism, and regularly clean and repair the equipment to keep the equipment in the best condition.
How to solve the problem of filter blockage in decanter centrifuge?
1. Regular inspection and maintenance:
Regularly inspect the decanter centrifuge, especially the filter part, to ensure that there is no accumulation of debris.
Clean the filter to remove particles and dirt attached to it.
2. Adjust material pretreatment:
Before the material enters the decanter centrifuge, pretreatment such as screening, crushing or dissolving is performed to reduce the concentration and viscosity of large particles entering the equipment to reduce the risk of filter blockage.
3. Optimize equipment operating parameters:
According to the properties of the material, adjust the speed, differential ratio and other parameters of the decanter centrifuge to improve separation efficiency and reduce filter clogging. Monitor the operating status of the equipment to identify and solve potential problems in a timely manner.
4. Use anti-clogging filters:
Consider using filters with special structures, such as self-cleaning filters or replaceable filters, to reduce the risk of clogging.
5. Strengthen staff training:
Train operators to understand the key points of operation and maintenance of decanter centrifuges and improve the efficiency of equipment use.
6. Establish emergency plans:
Develop emergency plans for filter blockage, including emergency treatment procedures, spare filter replacement, etc., to ensure that the equipment can quickly resume normal operation when blockage occurs.
