Abstract
The utility model discloses a filter disc for a disc vacuum filter, which is composed of a sintered plate made of multiple layers of sintered metal meshes, a wrapping ring, an inner frame and a joint; the sintered plate is fan-shaped; two pieces of sintered plates clamp on two sides of the inner frame and are welded to form a hollow fan-shaped filter board; the warping ring surrounds on the periphery of the hollow fan-shaped filter board; and the joint is installed at a position close to the center of circle of the hollow fan-shaped filter board. The filter disc has advantages of no obstruction, fast filtration, thick filter cake, fast dewatering, stable negative pressure, cleaning resistance, firmness and durability; and the disc vacuum filter with the filter disc has characteristic of large treating capacity, low water content of the filter cake, simple cleaning device and cleaning process and long service life.
Description
Technical field
The utility model relates to a kind of disc vacuum filter filter disc.
Background technology
So-called disc vacuum filter, be that the fan-shaped filter disc of multi-disc pieces together a circular disk, be through on the main shaft by a plurality of vertical disks, the horizontal rotating circular disk filter of forming by parts such as dispensing head, feeder trough, discharge port, stirring system, transmission system, the pumped vacuum systems of drawing water again, operation principle is similar to vacuum-type drum filter, on the disk filter disc successively by transition region, filtering area, dry section, scrape and unload the district, circular flow is filtered continuously, cake dewatering, is scraped the work of unloading.It is that a class filter area is big, occupation of land advanced person little, that treating capacity is big, filter cake moisture content is low filters machinery.
Existing disc vacuum filter has filter cloth disk filter, ceramic disk filter, sintering PE disk filter.
The filter disc of filter cloth disk filter is the hollow fanning strip that adopts porous plate or crin net to be welded, the outsourcing filter cloth.
The ceramic disk filter is to adopt capillary ceramic plate to do filter medium, and except that the operation characteristic with continuous high-efficient, its filtration mechanism has new breakthrough.One, the micropore behind the sintering has capillarity, can suck moisture in the filter cake, makes cake dewatering easier; Two, the micropore that soaks can stop air to pass through, and also can keep enough vacuum with littler vavuum pump.The pottery filter disc is two gluing forming of sintered ceramic microwell plate.
Sintering PE disk filter, similar ceramic disk filter, but microwell plate is to adopt that PE is powder sintered to form.Its hydrophily is relatively poor, so filter cake moisture content is higher.
More than three kinds of existing disk filters, because its filter material all belongs to the in-depth filtration material, there is the part solid particle to be stopped in filter material inside by filter material, and filter material is thick, and (it is lower to reach 1～10mm) voidage, therefore filter material stops up easily, easy cleaning not, the cleaning amount is big, often needs to increase ultrasonic wave and cleans and the pickling two procedures.Therefore cleaning is bigger with acid and filter material consumption, and use cost is higher, and maintenance work is more.Be used for 300 order Iron Ore Flotation slurry dewatering and filtering as the ceramic disk filter, expense reaches 8 yuan/ton.
The utility model content
The purpose of this utility model is to provide a kind of disc vacuum filter filter disc, so that filter disc is difficult for stopping up, is convenient to clean.
To achieve these goals, solution of the present utility model is:
A kind of disc vacuum filter filter disc, form by sintered plate, bound edge circle, inner frame and joint that the multi-layer sintering woven wire is made, it is fan-shaped that sintered plate is, two sintered plates are clipped in the both sides and the welding formation hollow Sector filter plate of inner frame, the bound edge circle be wrapped in the hollow Sector filter plate around, joint is installed in the hollow Sector filter plate by the position in the center of circle.
Described sintered plate is to be formed by multilayer stainless steel cloth sintering.
Described inner frame is a metal framework, two sintering plate holder metal frameworks all-metal hollow Sector filter plate that is welded.
Described inner frame is made by stainless steel material, and two stainless steel cloth sintering plate holder stainless steel inner frames also wrap stainless steel bound edge circle and form the fan-shaped filter disc of all steel hollow.
The sintered plate of described multi-layer sintering woven wire be by at least two to three layers of crin net and at least the superimposed sintering of one deck precise silk screen form.
The sintered plate of described multi-layer sintering woven wire is to count silk screen and the superimposed sintering of another layer 100 order silk screen forms by the extraordinary net of two-layer 12*64, one deck 100 order silk screens, a floor height order, wherein high order is counted one deck that silk screen is the extraordinary net of 1250#, 850#, 795# and 630#, high order is counted silk screen and is played the decision filtering accuracy, other silk screen plays a part to strengthen supporting, and is formed with certain thickness porous network simultaneously.
After adopting said structure, the utility model because sintered metal mesh (normally sintered stainless steel silk screen) as filter medium, easily stop up difficult problem of cleaning thereby improved existing filter, simultaneously owing to employing Metal Material Welding structure, so temperature tolerance is better.
And, sintered metal mesh is because the hydrophilic absorbent of porous network, has the ability that the suction filter cake moisture stops gas to pass through equally, this high filter cake moisture content of bubbling pressure from the multi-layer sintering woven wire low (5um filter plate bubbling pressure reaches 7000Pa, and filter cake moisture content is less than 15%) can prove the ability of its suction choke.Sintered metal mesh is owing to adopt welding procedure to be made into filter disc, and bulk strength and temperature tolerance significantly improve, and the filter cloth ceramoplastic all is not so good as this filter disc.
In addition, if sintered plate has only one deck or several floor height order to count the silk screen filtration, because of its minute aperture layer very thin (having only tens microns usually), majority is a clear opening, be cake filtration fully, filtrate enters from the crin net from precise silk screen and flows out during filtration, and solid particle is stopped on the precise silk screen surface, can not be blocked in the filter material, therefore be more prone to clean, by blow-back or liquid backwash even only adopt surface washing, just can clean up, more there is not the situation of obstruction.
In a word, adopt sintered metal mesh do filter disc have filter fast, filter cake is thick, dehydration is fast, negative regulation and many-sided advantage such as sturdy and durable.Therefore, adopt that the disc vacuum filter of sintered metal mesh filter medium just has also that treating capacity is bigger, filter cake moisture content is low, cleaning device and many superior functions such as cleaning is simple, long service life.
Sintered metal mesh is a kind of advanced person's a novel filter material, but has not been patented product, yet, also do not see report and the example that sintered metal mesh is applied to disc vacuum filter at present.Therefore, adopting sintered metal mesh as filter medium, make all-welded filter disc, become the sintered metal mesh disc vacuum filter, is the utility model initiative.
Further specify content of the present utility model below by embodiment.
