Automatic Self Cleaning Filtration System For syrup
Self cleaning filter Working principle
Construction and working principle: Scraper automatic self cleaning filtration system consists of the filter housing, filter mesh, scraper system, pressure measuring system, industrial control computer system and auto-discharge system. Raw materials media gets into the strainer through the inlet and the impurities which are larger in size than filter screen gap are intercepted on the side of strainer. After the system in operation for a certain time, when the pressure difference between inlet and outlet reaches pre-determined value (the value can be empirical value or debugging value ) , the industrial control computer will send a command to rotate the scraper and brush reducer to automatically remove the dirt on the filter screen. The control system can calculate working time and diversion of the scraper automatically according to different medias and the level of dirt intercepted. As the impurities collected to a certain amount,the discharge will open the valve to discharge and contol the time of discharge automatically. So repeatedly, the system can maximize the filtration
effect of impurities removal and self cleaning while minimize the wear on the filter mesh.
Self cleaning filter Design Features
1) With all-inclusive new design of hob, the system increases the effect of shoveling, scraping, displacement compensation, spring compensation, the cross of shoveling and scraping and controling the rotation direction of scrape on the basis of the original scraper design. The new design is more applicable to filtering the stripy media (such as fibre).
2)Utilize the scraper and the wedge-shaped angle that form a shear force, which can cut away any dirt and make it discharge with the opened valve.
3)The coloured LCD can display the pressure of inlet and outlet, the pressure differential curve and the running situations of all facility.
4)The industrial control computer functions:automatic adaptive tracking system, auto-control the scraper running time and discharging time.
5)The industrial control computer with ethernet card can achieve remote observing and controlling.
6)The standard industrial process control DCS interface connect with the centralized control system.
7)USB interface can connect with external keyboard and mouse to set the parameters of system.
8)It has warning function for system overvoltage, facility fault and system fault self-diagnosis.
