Abstract
The utility model relates to the improvement of the filter frame (or filter plate) of a filter press, which belongs to the solid-liquid separation machine. The utility model is characterized in that the pressing surfaces of the two sides of the filter frame (or filter plate) are glued with an elastomeric gaskets which has the functions of corrosion resistance and heat resistance; the elastomeric gaskets is provided with feed inlets and liquid holes; the shape of the elastomeric gasket is coincided with the shape of the pressing surface of the filter frame (or filter plate). The pressing surface of the composited filter frame (or filter plate) need not be processed; the utility model has the advantages of short periodicity, low cost, convenient use and reliable sealing.
Description
The utility model relates to the improvement of filter press filter frame (or filter plate), is solid-liquid separation mechanics.
In the existing at home and abroad filter press, filter frame and filter plate are mainly formed or cylinder iron cast through mold pressing by plastics and form.Because filter press inner chamber operating pressure is higher, the seal face of (chamber-type press filter does not have filter frame, has only notch board) must satisfy seal request between plate and frame or plate and the plate, and the sheet frame seal face that mold pressing or casting form is because contraction can't reach seal request.Therefore, when horizontal pressure and casting, the thickness of sheet frame seal face leaves bigger chipping allowance, so that seal face is rough milled and finish-milling processing, makes its flatness, and roughness etc. reach job requirement.With hydraulic pressure sheet frame is carried out Leakage Test again after the machined.Obviously, the production cycle of this sheet frame is longer, not only consumes manpower and electric power, and owing to chipping allowance has reduced stock utilization greatly.
In the prior art, also have and a kind ofly on the seal face of filter frame (or filter plate), slot, and in groove, be embedded the structure of sealing ring.Though this structure can solve sealing problem, part also comes with some shortcomings: (1) seal face fluting has weakened the intensity of filter frame (or filter plate).(2) fit tolerance of sealing ring and notch has determined that the dimension precision requirement of sealing ring is higher, and this sealing ring is thicker, so its processing charges is all relative with material cost higher.(3) opened groove on the seal face after, in order not reduce the intensity of filter frame, must increase the width of seal face.Like this, effective filtration area reduces to some extent.(4) installation requirement height.Sealing ring cooperates if tension is difficult to when then changing sealing ring take out in the future with notch, if loose excessively, then moves in (sheet frame must be drawn back during the filter press discharging) process repeatedly in use, and sealing ring is easy to come off.For above-mentioned reasons, this structure is not seen penetration and promotion after on probation.
Task of the present utility model is to overcome the above-mentioned deficiency of existing in prior technology, and provides a kind of with short production cycle, and production cost is low, easy construction, reliable sealing filter frame and filter plate.
The utility model proposes of task is finished by following technical proposal.On the seal face of filter frame or filter plate, paste the elastomeric pad of the anti-corrosion heatproof of one deck, for example: the rubber sheet gasket of three millimeters thick.This pad has feed liquid hole and washing lotion hole etc., thereby its shape and sheet frame seal face are fitted like a glove (as shown in Figure 3).This pad can stick on the sheet frame seal face by the binding agent (as epoxy resin etc.) of anti-corrosion heatproof, thereby pad and filter plate or filter frame are become one, and has constituted compound filter plate or compound filter frame (as shown in Figure 1).
Embodiment:
For plate and frame filter press, pad preferably is bonded at the filter frame both sides, because filter frame is lighter than filter plate, is convenient to operation; For chamber-type press filter, pad is bonded at a side of filter plate, as all being bonded at the left side.Then have only a rightmost filter plate to need both sides to paste pad.Earlier with the seal face wiped clean, with the very thin binding agent of brush brush one deck, again elastomeric pad is sticked then before pasting, and by flat.After treating its curing, pad and filter frame (or filter plate) have just become one securely.For the polypropylene sheet frame, can adopt the rubber sheet gasket of acid and alkali-resistance.The not only anti-corrosion heatproof of this pad, and good springiness, intensity is also high; Binding agent can adopt epoxy resin, and it not only has excellent bond performance, and in solidification process, do not have other volatile byproducts and generate, and also heat-resisting, cold-resistant, mildew-resistant, impact resistance is dissolved in any solvent hardly, except that acid with strong oxidizing property, inoic acid, alkali, all highly stable in the salt.
The accompanying drawing drawing is described as follows:
Fig. 1 is a compound filter frame schematic diagram of the present utility model.Wherein
1--polypropylene (or cast iron) frame 2--elastomeric pad
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the schematic diagram of elastomeric pad.
Fig. 4 is the B-B profile of Fig. 3.
Compared with prior art, compound filter frame of the present utility model (or filter plate), its structure and processing mode all have obvious improvement, and it has following advantage:
(1) production cost reduces: compare with present mass-produced sheet frame, compound filter frame (or filter plate) need not the compression face rough milled with essence after mold pressing or casting and mills, thereby the investment that can save two milling machines, also can save man-hour and the electric power of milling processing, and chipless, the stock utilization height.
(2) production cycle shortens: the seal face of filter frame both sides is stained with elastomeric pad, can finishes in two minutes, and the Milling Process of two procedures needs tens minutes at least with plain-milling machine; In addition, glued elastomeric pad after, hydraulic pressure Leakage Test operation can be removed from.
(3) sealing property improves: elastomeric pad has been arranged, can accomplish after sheet frame compresses not have to leak and filter.
(4) cost of composite bed is lower: the structure that is embedded sealing ring with fluting is compared, the elastomeric pad of compound filter frame (or filter plate) is very thin, materials are economized, manufacturing cost is also low (because the pad requirement on machining accuracy is low, and the monoblock square stock can overlap and be cut into a series of pads that vary in size and be used for serial sheet frame, thereby stock utilization is also high); The required binding agent consumption of each filter frame (or filter plate) also seldom.
(5) long service life: the structure that is embedded sealing ring with fluting is compared, the pad strong adhesion of compound filter frame (or filter plate), and difficult drop-off, and also the intensity of sheet frame is not weakened.
(6) install and change conveniently: the sheet frame that is embedded sealing ring with fluting is compared, the elastomeric pad of compound filter frame (or filter plate) is pasted convenient rapidly, use after the several years if need to change pad, owing to there is not groove, as long as blade is inserted perk between pad and the seal face, one draws and can take pad off, brushes a layer binder again, just can stick new pad at once.
