Abstract

The utility model discloses an unsealing fixed disk type filter, comprising a filter tube. The utility model is characterized in that the filter tube is fixedly provided with a plurality of filtering disks, the outsides of which are sleeved with filtering bags. The utility model adopts the structure; each filtering disk is firmly welded on a filter tube with holes; a certain distance is left between the adjacent filtering disks so as to be convenient to bundle the filtering bags; the upper part of the top filtering disk is parallel and level with the top part of the filter tube which has the functions of fixing the filtering disks and guiding the filtrate; the filtering bag also can change single filtering bag of a detachable filtering disk into an integrated big filtering bag, and the single filtering disk is sleeved on each filtering disk; all the filtering disks are sleeved by a straight cylinder type or a serial gourd big filtering bag; each filtering disk is bundled on the filter tube by a cable tie; therefore, the whole big filtering bag solves the problem of air leakage sealing and increases the filtering area.

Description

No sealing and fixing disc filter

Technical field

The utility model relates to the filter plant of the refining preceding particle residue of chemical products.

Background technology

The filter of particle residue mostly adopted filter stick, filter cloth, filter paper and also use before chemical products were refining, was the filter method of power with steam.Shortcoming is that volume is big, wastes a large amount of steam, and life cycle is short, the cost height, and filter area is little, and filtration time is long.Domesticly in recent years generally adopting removable disc filter, is power with the pump, and filter area is big, and filtration time is short, and life cycle is long, low cost and other advantages.Present removable disc filter has a plurality of filter discs, shown in Fig. 1,2,3,4, comprise housing 9, filter disc 1 outside in the housing 9 is surrounded by filter cloth bag 5, filter disc 1 is provided with filtering holes 4 and center liquid collecting hole 8, there is fixed axis 3 centre, and a plurality of filter discs 1 are gone here and there on center fixed axle 3, compress with hold-doun nut 7 above.Have sealing surface 2 contact between dish and the dish,, just can play sealing function, otherwise filter residue can enter the material from the interstitial hole of filter cloth bag 5 (go here and there the hole of using when overlapping fixed axis), and not have filtration because filter cloth bag 5 must be pressed in the middle of two sealing surfaces 2.But filter cloth is relatively thin soft, creases easily, and compacting between such two sealing surfaces needs with just fixing very energetically, easily make the filter disc distortion, and the silk on fragile hold-doun nut and fixed axis top in case seal badly, will cause a large amount of wastes.

The utility model content

Problem to be solved in the utility model is the poorly sealed problem that solves original disc filter, provides a kind of sealing effectiveness not have the sealing and fixing disc filter preferably.

The technical solution of the utility model is: no sealing and fixing disc filter, comprise chimney filter, and it is characterized in that: be fixed with several filtering tables on the described chimney filter, the outer cover of several filtering tables is equipped with filter bag.

Below be the further improved technical scheme of technique scheme:

As a kind of variation, has spacing between the adjacent filtering table.

The further technical scheme of such scheme, the spacing between the adjacent filtering table are 6～10cm.

Another changes, and its top of the filtering table that topmost is provided with flushes with the top of chimney filter.

One of variation of filter bag in the such scheme, described filter bag are the straight barrel type filter bag of one.

The formed shape of several filtering tables that is fixed with in two of the variation, the shape of described filter bag and chimney filter is corresponding and be structure as a whole.

Further improve, and the corresponding filter bag position, spacing position between the adjacent filtering table is provided with stopping means.

Further improve, described stopping means is a band of tying up filter bag again.

The utility model adopts said structure, filtering table in original technology, the profile of chimney filter do not change, but removed the middle sealing surface in filtering table top and bottom, and increased the area that filters, each filter disc is welded on a chimney filter with holes, certain distance is arranged between filtering table and the filtering table, between 6-10cm, be convenient to tie up filter bag, the filtering table top at top is concordant with the top of chimney filter, chimney filter has played the fixation to filtering table, again filtrate is played guide functions simultaneously.Filter bag is also by the big filter bag that single filter bag on each filtering table is changed into one that is socketed in of removable filter disc, straight barrel type or the big filter bag of string cucurbit shape entangle all filtering tables of filter, all be tied on the chimney filter between each filtering table with band, whole so big filter bag has just solved poorly sealed problem, and increased filter area.

Below in conjunction with drawings and Examples the utility model is further detailed

The specific embodiment

Embodiment, as shown in Figure 5, the no sealing and fixing disc filter that the utility model is designed, comprise chimney filter 3, be fixed with several filtering tables 1 on the chimney filter 3, the outer cover of several filtering tables 1 is equipped with filter bag 5, chimney filter 3, filtering table 1 and filter bag 5 all are arranged in the airtight housing, version among its shell structure such as Fig. 1, filtering table 1 is provided with filtering holes, has spacing between the adjacent filtering table 1, spacing is 6～10cm, filtering table 1 its top that topmost is provided with flushes with the top of chimney filter 3, and filter bag 5 is the straight barrel type filter bag 5 of one, and corresponding filter bag 5 positions, the spacing position between the adjacent filtering table 1 are provided with the band 10 of tying up filter bag 5.

In the foregoing description, the shape of filter bag can be made corresponding with the formed shape of several filtering tables that is fixed with on the chimney filter and be structure as a whole, and promptly forms string cucurbit shape.

Also can make the big filter bag of straight barrel type.

Innovation part of the present utility model is: need not sealing surface between the filtering table, but be fixed on the chimney filter, filter bag changes the big filter bag of integral type into by single filter bag.
