Intelligent filter control method

Abstract

The invention discloses an intelligent filter control method. The method comprises the following steps: cyclically filtering electroplating liquid during normal operation, performing real-time monitoring and starting cleaning according to requirements, performing first-time emptying treatment before cleaning is needed, and returning filtrate remaining in a filter into an electroplating liquid medicine tank through a filtrate outlet of the filter; cyclically and forwardly cleaning the filter by using medicine cleaning water; performing backward gas-water mixed washing on the filter, and mixing gas and water to form cleaning foam; stopping backward gas-water mixed washing, performing second-time emptying treatment, returning the medicine cleaning water remaining in the filter into a cleaning tank from a to-be-filtered liquid inlet of the filter, and then emptying the cleaning tank to recycle the medicine cleaning water; mixing gas and clean water to backwardly washing the filter; after cleaning is completed, draining waste water in the filter from the to-be-filtered liquid inlet of the filter to a waste water drain outlet. The filter control is precise, the filter is cleaned in real time, a filter element does not need to be replaced, the cost is reduced, and the production cost of an enterprise is reduced by recycling the electroplating liquid.

Description

technical field [0001] The invention relates to a liquid filtration control method, in particular to an intelligent filtration control method. Background technique [0002] During the electroplating process, it is often encountered that the process and operation control are under normal conditions, but the plated products are not satisfactory, and defective products such as burrs and pitting often occur. Practice has proved that this is directly related to the cleanliness of the plating solution. How to control the cleaning of the electroplating solution and the treatment rate of the electroplating surface, the role of the filter cannot be underestimated. Therefore, in today's rapid development of the electroplating industry, the filter equipment plays a pivotal role. [0003] However, there are still some deficiencies in traditional electroplating solution filters, for example: (1) most of the existing filters on the market are manually operated, and their structure and pri...

Problems solved by technology

[0003] However, there are still some deficiencies in traditional electroplating solution filters, for example: (1) most of the existing filters on the market are manually operated, and their structure and principle are simple but cumbersome to operate, requiring a lot of labor costs; (2) existing After using the filter element for a period of time, it cannot meet the quality requirements, and it needs to be removed and cleaned manually or replaced with a new filter element, which increases labor costs. When cleaning and replacing the filter element, the expensive electroplating solution is also drained with the waste liquid, wasting The electroplating solution is wasted, the water source is wasted, and waste water is also generated, and the installation of the subsequent filter element depends on the worker's technology and work responsibility, which may easily cause the filter element to not be sealed, the bath solution cannot be filtered effectively, and the filtering effect is difficult to guarantee
