Abstract
The utility model relates to a septum filter plate having self sealing function, wherein, the septum is located on the frame of the filter plate. The single face or double faces of the sealing combing face of the filter plate is opened with a concave groove. The sealing combing face of the septum is provided with a convex table matching with the concave groove of the filter plate. The bottom of the convex table is provided with one ring or two rings or multiple rings of lip edges. The septum part neighboring to one ring or two rings or multiple rings of lip edges is provided with a concave groove to form an open damping cavity together with one ring or two rings or multiple rings of lip edges respectively. The open damping cavity is combined with the concave groove of the plate core by sealing and pressing.
Description
Technical field
The utility model relates to a kind of membrane filter plate with self-sealing function, belongs to membrane filter plate and makes the field.
Background technology
Granted publication CN2461636Y, title " a kind of membrane filter plate of novelty ", barrier film in this membrane filter plate is positioned on the filter plate frame, single or double has Baltimore groove around the filter plate, around the barrier film boss that is complementary with Baltimore groove is arranged, leave the gap between boss in the barrier film and Baltimore groove and adopt adhesive its seal bond.Its weak point: when the barrier film hypertonia, produce phenomenons such as fluid leaks between barrier film and filter plate inevitably, not only excessively low every efficient, and also energy loss is big.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, designing between a kind of barrier film and filter plate increases with fluid pressure, can realize the membrane filter plate of self-packing novelty.
Design: design: in order to realize above-mentioned purpose of design.The sealed faying face of barrier film is provided with the boss that is complementary with the filter plate Baltimore groove and the boss bottom has a circle or 2 to enclose or the design on multi-turn lip limit, is one of feature of the present utility model.The purpose of doing like this is: the boss bottom has the diaphragm portion that a circle or 2 encloses or multi-turn lip limit and is enclosed or multi-turn lip limit is adjacent to be provided with groove, this groove constitutes open damping cavity with a circle or multi-turn lip limit respectively, when this open damping cavity is touched mutually with the wall of plate core groove, stressed back, lip limit strain forces the lip limit to form dynamic band means of press seals with plate core groove wall and combines or the linear sealing combination; The 2nd, when fluid is injected in the sealing damping cavity and acts directly on the lip limit by the fluid between barrier film and filter plate, the lip limit is subjected to the active force of fluid and strain, forcing lip limit and filter plate groove wall to form dynamic band means of press seals combines or the linear sealing combination, that is to say, flow into the fluid pressure in the sealing damping cavity, make the self sealss performance of the damping cavity of a circle or multi-turn lip limit and filter plate groove formation reach the effect of dynamic seal (packing), guaranteed the positiver sealing between barrier film and filter plate.Its technical scheme: a kind of membrane filter plate of novelty, barrier film is positioned on the filter plate frame, the single or double of the sealed faying face of filter plate (1) has Baltimore groove (5), the sealed faying face of barrier film (2) is provided with the boss (6) that is complementary with the filter plate Baltimore groove, one circle or 2 circle or multi-turn lip limits (3) are arranged at boss (6) bottom, with a circle or the adjacent diaphragm portion of 2 circles or multi-turn lip limit (3) is fluted and constitute open damping cavity (4) with a circle or 2 circles or multi-turn lip limit (3) respectively, open damping cavity (4) and groove in the plate core (1) are sealing and push and combine.
The utility model is compared with background technology, and the one, barrier film is inlayed portion boss bottom by a circle or 2 or the design of the sealed damping cavity that constituted of multi-turn lip limit and filter plate groove, has realized the self sealss of barrier film and filter plate; The 2nd, barrier film adopts polypropylene and other elastomer to make, not only to satisfy the intensity of damping cavity hermetically-sealed construction, and after damping cavity lip limit was subjected to the effect of fluid pressure, the strain on lip limit had realized that the plasticity self sealss on lip limit and low cost of manufacture, durable wear decrease; The 3rd, because therefore good seal performance pushes the efficient height, production cost is low, has obtained beyond thought economic benefit and social benefit.

Fig. 3 is the structural representation of barrier film.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～3.A kind of membrane filter plate of novelty, barrier film is positioned on the filter plate frame, the single or double of the sealed faying face of filter plate 1 has Baltimore groove 5 and adopts existing technology injection moulding or compression molding, the sealed faying face of barrier film 2 is provided with the boss 6 that is complementary with the filter plate Baltimore groove, one circle or 2 circles or multi-turn lip limit 3 and existing technology injection moulding of employing or compression molding are arranged at boss 6 bottoms, the diaphragm portion adjacent with a circle or 2 circles or multi-turn lip limit 3 is fluted and constitute open damping cavity 4 and adopt existing technology injection moulding or compression molding with a circle or 2 circles or multi-turn lip limit 3 respectively, open damping cavity 4 is the sealing extruding with groove in the plate core 1 and combines, the filter plate main component is a polypropylene, thermoplastic resins such as polyethylene, inorganic filling modifying agent, processing aid, barrier film main component are polypropylene-polyethylene, fluororesin, EvA, but 5BS natural rubber or synthetic rubber or elastic material, processing aid.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
Claims (2)
