Embodiment Construction
[0024] The microporous ceramic disc for water filtration is composed as follows:
[0025] 1) Overall structure and internal and external sealing: see figure 1 , A set of ceramic discs is composed of outer flow disc 1 and inner flow disc 2. Both the outer flow disc and the inner flow disc are composed of upper and lower discs; the gap between the upper and lower discs is called a crack.
[0026] see figure 2 , Outflow disc 1 is composed of upper outflow disc 1B and lower outflow disc 1A. There is a gap between the upper and lower outflow discs. The outermost circular edges of the upper and lower discs are both provided with grooves 1.11, which are filled with polyurethane glue 1.12 to form an outer sealing ring 1.1. see figure 1 , figure 2 , image 3 , The inner sealing groove 1.4 with the inner rubber sealing ring 3 is opened beside the center hole 11A of the upper and lower disc surfaces of the outer flow disc 1.
[0027] Similarly, see Figure 5 , The inner flow disc 2 is comp...

Abstract
The invention relates to a micropore ceramic plate and a filtering column for filtering water. Each set of ceramic plate is composed of outer and inner flow plates with vertical outer or inner raw mater channels. Upper and lower discs are both arranged on each plate; an outer sealing ring is arranged at the outmost circle edge; an inner sealing ring is arranged in a slot at the center; a raw water fan-shaped horizontal channel connected with the vertical raw material channel is respectively arranged on the surfaces of upper and lower planes; a purified water central hole is formed in the periphery of the central hole; a purified water crack inner seeping channel and a seeping channel are respectively arranged in two disc cracks of the outer and inner flow plates; a crack seal for preventing raw material from leaking out of the crack is arranged; the filtering column is composed of at least one set of ceramic plates, a plastic gland, a stainless steel sealing cover and a central screw rod fastened in a column shell; and a raw water inlet, a raw water outlet and a purified water outlet are all formed at the upper or lower end. The ceramic plate is high in strength, excellent in thermal chemical stability and long in service life; a filtration and infiltration surface is large, the efficiency is high, and the purified water collection is maximal; and the quantity of the ceramic plates of the filtering column is high and can fully meet the industrialized requirement. The micropore ceramic plate is especially suitable for the filtration and separation of running water, earth-containing water, beverage juice, nuclear radiation water, air, oil, and the like.
Description
[0001] (1) Technical Field: The present invention relates to a filter assembly and device used in water treatment. It belongs to the separation of physical methods (B01D). (2) Background technology: [0002] With the increase of human industrial activities and consumption activities, water resources are also subject to certain pollution. In recent years, filtration devices and filter materials in water treatment have been greatly developed, and they are different for different raw water purification. [0003] The traditional and widely used water treatment filter material is organic membrane (according to the pore size of 0.1-1.0um, can be divided into: MF, UF, NF, RO membrane), NF and RO membrane materials are mainly polysulfone organic materials The total thickness of the composite membrane and the filter layer of the composite membrane are generally below 0.4mm. The skin thickness of the filter layer is only 20-200nm. If the skin layer is thicker, the high permeability of the m...
