Abstract
The utility model relates to a membrane filter plate, and in particular relates to a non-lug boss membrane filter plate mechanism, aiming at solving the problems that the whole membrane filter plate needs to be supported through a supporting lug boss due to a core plate arranged inside the membrane filter plate, but the compressing and dehydrating level of materials can be influenced by the supporting lug boss when a filter press is operated, and a membrane plate cannot bear the force uniformly in the prior art. The non-lug boss membrane filter plate mechanism comprises membrane plates (1). The non-lug boss membrane filter plate mechanism is characterized in that two symmetric membrane plates (1) made of elastic materials are provided; feed openings (2) are formed in the membrane plates; each of the membrane plates (1) is characterized in that the side edge is thicker, the middle is thinner, and water running bulges (3) are uniformly distributed on the outward surface; the two membrane plates are adhered by a back-to-back manner, and the side edges are sealed and fixed; a sealing cavity gap (4) is formed between the middles of the two membrane plates.
Description
Technical field
The utility model relates to a kind of membrane filter plate, especially relates to a kind of membrane filter plate mechanism without boss.
Background technology
Existing membrane filter plate, basic structure comprises two diaphragms and a central layer.Central layer is very thick, does not have elasticity, under condition of high voltage, if discontinuity is easy to deform and even breaks.For this reason, be all provided with 4～8 support rims on the diaphragm on filter plate two sides, even more, object is to cause central layer unbalance stress in order to prevent filter plate deflection.Therefore, when polylith membrane filter plate folded by time, between filter plate and filter plate, by support rim, mutually support.Because support rim does not have deformation behavior, so the minimum clearance between filter plate is fixed, material maximum compression ratio is therebetween just limited, causes under certain situation fully extrusion dehydration of material.On the other hand, during diaphragm pressing, owing between filter plate and filter plate not being diaphragm and the stressed conduction of diaphragm, but the stressed conduction of support rim and boss, and boss is mainly passed to the barrier film face with boss fusion place pressure, so diaphragm sheet is stressed very inhomogeneous.When membrane filter plate is stressed while squeezing material, during particularly for the larger material of Ya Shrink, inevitably cause the phenomenons such as filter plate distortion, crack, fracture.
Utility model content
The utility model is to provide a kind of without boss membrane filter plate mechanism, it is mainly to solve the existing membrane filter plate of prior art because inside has central layer, therefore need to adopt support rim to be used for propping up whole filter plate, and when filter press is worked, support rim can affect compression and the degree of dehydration of material, and the problem that causes diaphragm discontinuity.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Of the present utility model a kind of without boss membrane filter plate mechanism, comprise diaphragm, described diaphragm is symmetrical two, which is provided with charging aperture, and diaphragm is that elastomeric material is made, diaphragm edge is thicker, centre is thinner, and its outside one side is provided with the uniform projection of leaking water, and two diaphragms are bonding back-to-back, edge is airtight fixing, at the middle part of two diaphragms, forms airtight lacuna.This diaphragm has extraordinary elasticity, and its inside is supported without central layer.Owing to having cancelled center brace panel in this New type membrane filter board mechanism, then originally for the protection of the support rim of central layer, also cancelled.Like this, diaphragm filter press, in the process of press filtration, has not had the restriction of the protrusion height of support rim between filter plate, and the gap between filter plate and filter plate can fully be compressed, and material dewatering is therebetween more abundant.Meanwhile, owing to there is no ridge, filter plate surface is stressed evenly, and diaphragm is difficult for breaking.
As preferably, the thickness of described diaphragm edge is greater than the thickness at its middle part.Diaphragm has good elasticity, during use, can in the airtight lacuna between two diaphragms, pass into gases at high pressure or liquid, and diaphragm is bloated to both sides, and the material between extruding filter plate, realizes diaphragm pressing.
As preferably, the described protruding diameter of leaking water is 5-10 mm, and protrusion height is 5-10 mm.
Therefore, the utility model has been cancelled the support rim on membrane filter plate surface, makes polylith filter plate when press filtration is worked, the press filtration more fully of the material between membrane filter plate, and material dewatering effect is more thorough; And filter plate surface is stressed evenly, can extend the service life of membrane filter plate.The feeding manner of filter plate can adopt the various ways such as upper feeding, lower charging or angle charging, facilitates different material to select.This membrane filter plate production cost is lower, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is cross-sectional view of the present utility model.
Parts, position and numbering in figure: diaphragm 1, charging aperture 2, leak water projection 3, airtight gap 4, filter chamber 5.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: this example a kind of without boss membrane filter plate mechanism, as shown in Figure 1, Figure 2, comprise diaphragm 1, diaphragm is symmetrical two, and on it, angle is provided with charging aperture 2, the outer surface of diaphragm is all provided with the uniform projection 3 of leaking water, the edge of two diaphragms is airtight fixing, forms airtight lacuna 4 at middle part, and the edge of diaphragm is thicker, centre is thinner, and diaphragm is that elastomeric material is made.The thickness of diaphragm is reduced to middle part gradually by edge.The diameter of the projection 3 of leaking water is 8 mm, and protrusion height is 7 mm.
During use, membrane filter plate both sides are coated with filter cloth, and polylith filter plate is folded and is close together, and folded by the interior filling wet stock of rear formed filter chamber 6 to filter plate and filter plate by charging aperture, the moisture in material sees through filter cloth and flows out.Airtight lacuna 4 is interior can be filled with gases at high pressure or liquid, thereby makes diaphragm to the bloating of both sides, can the further press filtration to the material in filter chamber.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
