Description
Technical Field
The invention relates to a disc-tube type reverse osmosis membrane component system, in particular to a flow guide disc for a pressure-resistant disc-tube type membrane component.
Background
The disc-tube reverse osmosis membrane is an advanced reverse osmosis membrane and has a unique structural form, and the disc-tube reverse osmosis membrane column mainly comprises a membrane, a flow guide disc, a central pull rod, a shell, various sealing pieces with flanges at two ends, a connecting bolt and the like. The filter membrane and the flow guide disc are stacked together, fixed by the central pull rod and the end cover and then placed into the pressure-resistant shell to form a membrane column which is more and more widely used in the treatment of the garbage penetrating fluid, so that a better effect is achieved, but some problems also exist.
The dish tubular water conservancy diversion dish is an indispensable membrane element of dish tubular reverse osmosis membrane post, and the water conservancy diversion dish adopts the bump to support, plays the effect of lifting the weight of foot, and the bump of current water conservancy diversion dish adopts tiny point to support the diaphragm more, easily damages the diaphragm when operating pressure is too big. Two guiding disks and sealing washer are through inserting to close and provide the space of placing for the diaphragm, have completely cut off fresh water and dense water simultaneously, and the installation of current guiding disk is more troublesome because can only judge through manual experience and eyes whether the guiding disk aligns each other when the installation, whether can form smooth rivers passageway, not only expend the manpower, has also reduced the work efficiency of installation simultaneously. The current guiding plate on the market, when sealing washer both ends pressure differential was too big, certain displacement will take place for the sealing washer, leads to dense water fresh water to mix, influences the separation effect.
The invention further provides improvement on the problems existing in the operation of the disc-tube type flow deflector by analyzing the advantages and the disadvantages of the disc-tube type flow deflector in the process operation at home and abroad.
Disclosure of Invention
The invention aims to provide a flow guide disc for a pressure-resistant disc-tube type membrane component, so that the problems that the existing flow guide disc is inconvenient to mount, a moving ring is displaced when the pressure at two ends of an O-shaped sealing ring is overlarge, a membrane is easily damaged by fine convex points when the pressure is overlarge and the like are solved.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the utility model provides a flow guide disc for withstand voltage dish tubular membrane module, includes flow guide disc body, the centre bore of placing the central pull rod, dense cistern, O circle seal groove, the center department of flow guide disc body is equipped with the centre bore, and the centre bore position positive and negative structure of flow guide disc positive and negative is different, the little breast board positive and negative position of positive and negative correspond the size phase-match, and can seal and insert and close, the breach that forms after little breast board inserts and closes is the water purification collection mouth. The front surface and the back surface of the flow guide plate body are symmetrically provided with small holes and convex point rectangular thin strips which are continuously arranged behind the small holes, and the arrangement directions of the adjacent small holes and the convex point rectangular thin strips behind the small holes are opposite. The outer edge of the small raised breast board is provided with a plurality of concentrated water grooves along the axial center radial direction of the flow guide disc, an O-shaped sealing ring groove is arranged between the concentrated water grooves and the outer edge of the small raised breast board, and the height of the O-shaped sealing ring groove is half of that of the inserted O-shaped ring. The front and back sides of the outer edge of the flow guide disc body are provided with salient point grooves which can be tightly sewn and buckled.
The baffle plate is characterized in that the baffle plate comprises a baffle plate body, wherein the baffle plate body is provided with a baffle plate, the baffle plate is provided with a baffle.
The volume of the rectangular thin strips with the convex points on the surface of the diversion disc body is gradually distributed along the straight line from small to large.
And fine anti-skidding and anti-moving rubber threads are arranged in the sealing groove of the O-shaped ring.
Compared with the prior art, the invention has the advantages that: the small raised baffle plates on the front side and the back side in the middle of the flow guide disc and the flow guide disc body are symmetrically distributed, when the flow guide disc is installed, only the small baffle plates on the front side and the back side are inserted, and an installer does not need to judge whether the baffle plates are aligned through experience and eyes, so that the labor is saved, and the working efficiency can be greatly improved. The little bump of rubber on the little breast board can strengthen the resistance to pressure of whole subassembly, and can prevent that the guiding disc from connecting to take place to shift deformation under the high pressure.
The small holes on the flow guide disc body can effectively penetrate part of concentrated water, so that the pressure of the membrane assembly during operation is reduced, and the reverse osmosis membranes can be additionally arranged under the same pressure, so that the filtering effect is improved. The position that the rectangle sliver of bump rubber on the guiding disk body set up can increase the torrent of water, does benefit to the pollutant on diaphragm surface and flows to prolonged the dirty stifled cycle of membrane, the material of bump can increase the frictional force between water conservancy diversion piece and the diaphragm simultaneously, prevents that diaphragm both ends pressure from taking place dislocation displacement between diaphragm and the guiding disk when too big. The convex point is the protruding "point" of cuboid for current guiding plate, more can protect the diaphragm not damaged under pressure to increase the life of diaphragm.
Compared with the common flow guide disc, the O-shaped sealing ring groove of the flow guide disc increases the height of the groove, the height of the groove is half of that of the O-shaped sealing ring, and the O-shaped sealing groove is internally provided with the tiny anti-skidding threads, so that the O-shaped ring can be prevented from moving and shifting under high pressure, and the contact effect with a diaphragm is not influenced. The convex point groove symmetrical structure on the edge of the flow plate body can prevent the flow guide plate from shifting to a certain extent while playing a role in positioning during installation.
