Problems solved by technology

However, there are also some shortcomings in the ceramic filter, which are mainly manifested in: the ceramic plate made of two ceramic sheets bonded with glue is easy to be corroded by acid and alkali or organic solvents and falls off, low pressure resistance and short service life; overall sintering The resulting ceramic plate also has the problems of easy clogging and affecting the filtering effect; at the same time, the ceramic filter plate is fragile, and after the filter plate is damaged, there are problems of inconvenient installation and maintenance and high operating costs

Embodiment 1

[0025] Embodiment 1, with reference to attached Figure 1-3 .

[0026] A 1.5mm thick stainless steel plate is used to make two fan-shaped metal substrates 4 through a stamping process. A filter hole 2 with a diameter of 4mm is uniformly punched out on the metal substrate 4 corresponding to the filter area, and a diameter of 4mm is punched out at the position corresponding to the fixed flange of the filter. Two mounting holes 7 of 20 mm, one of the metal substrates 4 are curled and stretched to form a metal sealing plate 1, and two through holes are drilled under the metal sealing plate 1, and a filtrate outlet is welded on each through hole 8. Then align the two fan-shaped metal substrates 4 and weld them together to form a matrix, and the interior of the matrix naturally forms a cavity; then punch out two pieces of metal fibers with a thickness of 2 mm and an average pore size of 10 μm that are consistent with the shape of the metal substrate filter area Felt 3, two pieces o...

Embodiment 2

[0027] Embodiment 2, with reference to attached Figure 1-3 .

[0028] Others are the same as in Embodiment 1, except that a through hole is drilled below the metal sealing plate 1, a filtrate outlet 8 is welded on the through hole, and a metal sintered mesh 6 is also laid between the metal substrate 4 and the metal fiber felt 3.

Embodiment 3

[0029] Embodiment 3, with reference to attached Figure 1-4 .

[0030] Others are the same as in Embodiment 1, except that after the fan-shaped metal substrate 4 with the metal sealing plate 1 is punched out, several metal skeletons 5 are also arranged horizontally in it, and several metal skeletons 5 are connected with the fan-shaped The metal substrates 4 are welded together, and then two fan-shaped metal substrates 4 are aligned and welded together.

Abstract

The invention relates to a composite filter plate. The composite filter plate comprises a base body and 1-3 filtrate outlets fixedly connected with the base body and communicated with an inner cavity of the base body. Different from the prior art, the composite filter plate has the characteristics that the base body comprises two metal substrates which define the cavity, filter pores with diameters ranging from 1 mm to 10 mm are evenly distributed in each metal substrate and communicated with the cavity, and metal fiber felt or a metal powder sintered plate is laid on the outer side of each metal substrate. The metal fiber felt is formed through non-woven spreading, overlapping matching and high-temperature sintering of extremely fine metal fibers with micron-grade diameters, adopts a three-dimensional porous structure and has the characteristics of high porosity, large specific surface area, uniform pore diameter distribution, high pollutant holding quantity, high filter precision and the like; compared with ceramic filter plates, the composite filter plate is not fragile and is large in flow, resistant to high temperatures, high pressure and corrosion, reproducible, long in service life, easy to mold, good in compatibility with metal substrates and capable of being welded.

Description

technical field [0001] The invention relates to a filter, in particular to a novel composite filter plate applied to a disc vacuum filter. [0002] technical background [0003] Among the solid-liquid separation equipment, the ceramic vacuum filter is based on the principle of capillary micropores. It uses microporous ceramic plates as the filter medium and is designed by utilizing the water-permeable and air-tight characteristics of the micro-porous ceramic plates. It is a disc-type vacuum filter that works under negative pressure. machine. Its advantages are that the ceramic filter plate is wear-resistant and corrosion-resistant, has strong capillary action, and has remarkable energy-saving and consumption-reducing effects. However, there are also some shortcomings in the ceramic filter, which are mainly manifested in: the ceramic plate made of two ceramic sheets bonded with glue is easy to be corroded by acid and alkali or organic solvents and falls off, low pressure resi...
