Vertical Blade Oil Filter Filter High-Efficiency Precision Filter Without Residue Once Discharged​

The operation process of the automatic horizontal leaf filter: as the filtration time increases, more and more solid impurities are trapped on the filter screen, so that the thickness of the filter cake increases continuously, so that the filtration
The resistance increases, and the pressure in the tank increases. When the pressure rises to a certain value, it is necessary to discharge slag, stop the input of the liquid to be filtrated into the pipe, and blow the compressed air into the tank through the overflow pipe, and pour the liquid to be filtered in the tank into other containers. inside and blow dry the filter cake. Turn off the compressed air (manufacturers with conditions can use steam and hot nitrogen), open the butterfly valve, start the vibrator, make the filter plate vibrate, and shake off the filter cake on the filter plate
And it is discharged through the butterfly valve slag discharge port under the tank.
When the working time of the filter is very short and the pressure rises quickly, it is often caused by the blockage of the filter screen. At this time, the filter should be checked, and the filter should be placed in a bright place at a 45° angle to the filter.
Observe, if found to be blocked, it should be cleaned in time. The cleaning method of the mesh of the automatic horizontal blade filter:
1. Mechanical cleaning method:
Use 0.6-0.8MPa high-pressure water to spray and wash, put the filter screen vertically on the wooden board, the discharge port of the filter screen is facing down, and the nozzle of the high-pressure water and the filter screen are flat to form a 45° angle for spray cleaning. filter cleaning
Washing can also be washed with 0.3 0.5MPa steam, and its operation method is the same as high-pressure water spray washing, and it can also achieve good results. Pay special attention to the filter screen must not be countercurrent and countercurrent washing of the filter,
This can make the filter swell or even tear it. Do not use a brush or metal scraper to brush the filter screen, which will not only block the filter screen, but also easily scratch the filter screen.
2. Chemical treatment method:
The filter screen is cleaned in a pure pool. The cleaning solution is 10-15% NaOH solution (or a cleaning solution that has no corrosive effect on the filter screen), the temperature is 50 ^ 60"C, and the cleaning time is normal.
Not more than 3 hours, be careful not to use hydrochloric acid or detergents that generate free chloride ions, because it will seriously corrode the filter.
