Johnson Screen For Nutshell Filter
We Produce Wedge Wire Filter Element Products For Walnut Shell Filter.
Walnut shell filter (Nutshell filter) , including folding paddle, lower receiving screen(wedge wire screen filter), tank, upper water sieve(Johnson Screen Lateral Assemblies), stirring shaft and observation hole.
Walnut shell filters are lightweight filters, the main structure includes an upright cylindrical tank.
The upper part of the tank is provided with a water inlet pipe, and the lower part of the tank is provided with a water outlet. The mixing shaft is provided with a folding paddle, and the tank body is provided with a Johnson water distribution screen pipe above the folding paddle.
The lower part of the folding paddle is provided with a lower wedge wire water collection screen pipe, and the filter material with walnut shell as the filter material is arranged between the upper water distribution screen pipe and the lower water collection screen pipe in the tank body.
- Oily sewage enters the tank from the water inlet pipe.
- The material contacts with the filter material through the upper Johnson water distribution screen tube, and the filter material absorbs the oil dirt in the sewage, so that the oil content is reduced, and the sewage is discharged from the outlet.
- After a period of use, the filter material will lose its filtering effect due to the adsorption of excessive oil. At this time, the filter material needs to be backwashed to regenerate the filter material.
- During backwashing, the stirring shaft drives the folding blade to rotate, and the folding blade stirs the filter material to make full contact with the washing liquid, and repeatedly stirs to separate the oil from the filter material, so that the filter material is regenerated.
