Problems solved by technology

[0004] However, when the sludge contains impurities such as solid particles with a geometric size greater than 10 mm, the above-mentioned sludge concentration and dehydration treatment equipment needs to remove the large particles of solid impurities before further dehydration, otherwise it is easy to cause low sludge compaction , leading to low dehydration efficiency, serious and even damage to equipment

Embodiment 1

[0035] Such as figure 1 , figure 2 As shown, a composite filter cartridge filter includes a composite filter cartridge 1, four composite filter tubes 2, a first sealing plate 3, and a second sealing plate 4.

[0036] Both ends of the composite filter cartridge are open, such as image 3 As shown, the cylinder wall of the composite filter cartridge includes a filter cartridge inner orifice plate 7, a filter cartridge filter layer 8 and a filter cartridge outer orifice plate 9 from the inside to the outside, and the filter cartridge inner orifice plate, the filter cartridge outer orifice plate Filter holes 13 are provided. Wherein the filter cartridge filter layer is a filter screen. The total area of ​​the filter holes on the composite filter cartridge accounts for 50% of the total area of ​​the outer wall of the composite filter cartridge, and the diameter of the filter holes is 3mm.

[0037] Both ends of the composite filter tube are open, such as Figure 4 As shown, th...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that the number of composite filter tubes in this embodiment is 6, and the filter layer of the filter cartridge or the filter layer of the filter tube is filter cloth. The total area of ​​the filter holes on the composite filter tube accounts for 60% of the total area of ​​the outer wall of the composite filter tube; and the diameter of the filter holes is 4mm. The total area of ​​the filter holes on the composite filter cartridge accounts for 60% of the total area of ​​the outer wall of the composite filter cartridge, and the diameter of the filter holes is 4mm. And this embodiment is not provided with a pressure sensor and a moisture content sensor.

Embodiment 3

[0043] The difference between this embodiment and Embodiment 1 is that the number of composite filter tubes in this embodiment is one. The filter cartridge filter layer or the filter tube filter layer is a filter membrane. The total area of ​​the filter holes on the composite filter tube accounts for 70% of the total area of ​​the outer wall of the composite filter tube; and the diameter of the filter holes is 5mm. The total area of ​​the filter holes on the composite filter cartridge accounts for 70% of the total area of ​​the outer wall of the composite filter cartridge, and the diameter of the filter holes is 5mm. And the pressure sensor and the water content sensor of this embodiment are installed on the first sealing plate.

Abstract

The invention relates to the field of solid-liquid separation filters, and discloses a composite filter drum filter which comprises a composite filter drum (1), composite filtering tubes (2), a first sealing plate (3) and a second sealing plate (4), wherein two ends of the composite filter drum are opened; filtering holes (13) are formed in the wall of the filter drum; two ends of the composite filter drum are opened; filtering holes (13) are formed in the wall of the filter drum; the composite filtering tubes are arranged inside the composite filter drum; the first sealing plate and the second sealing plate are respectively arranged at the openings at two ends of the composite filter drum in a sealing cover manner; two ends of each composite filtering tube are arranged at the first sealing plate and the second sealing plate in a penetration manner. When the composite filter drum filter is used, physical properties and geometrical sizes of solid granules in treated substances are not strictly required, internal filtration and external filtration can be synchronously carried out, and solid-liquid separation indexes and efficiency are far superior to those of conventional filters.

Description

technical field [0001] The invention relates to the field of solid-liquid separation filters, in particular to a composite cartridge filter used for rapid dehydration of liquid-containing mixtures with complex components. Background technique [0002] With the rapid development of our country's economy, there are more and more mixtures that need to be treated with solid-liquid separation produced by water plants and large-scale water-using enterprises or related to water, such as industrial sludge, domestic sludge and field construction. The amount of complex river silt, river dredging mud, construction mud, etc. is huge; these silts and muds have high moisture content and the composition, physical properties, and geometric shapes of the solids contained are very complex. At present, the existing equipment for solid-liquid separation treatment has many deficiencies such as low dehydration index, low efficiency, high energy consumption, and difficult maintenance. [0003] Fo...
