Description

Dish tubular reverse osmosis subassembly of individual soldier's outdoor use

Technical Field

The utility model belongs to the technical field of water treatment facilities, concretely relates to outdoor dish tubular reverse osmosis subassembly of using of individual soldier.

Background

The conventional disc-tube type reverse osmosis component at present generally comprises a membrane, a flow guide disc, a sealing ring, a central pull rod and a membrane shell. The diaphragm and the diversion disc are stacked at intervals, the sealing rings are arranged in grooves on two sides of the diversion disc, connected by a central pull rod and placed in the diaphragm shell, and two ends of the diaphragm are hermetically arranged by metal end plates. The whole assembly adopts an open flow channel, the distance between adjacent flow guide discs in the assembly is about 4mm, and salient points distributed in a special mode are distributed on the surface of each flow guide disc. The convex points which are arranged specially enable the treatment liquid to form strong turbulence when flowing through the surface of the filter membrane, thereby increasing the permeation rate and the self-cleaning function, effectively reducing the membrane blockage and the concentration polarization effect, and successfully prolonging the service life of the membrane; the scale on the membrane is easy to clean during cleaning, and the disc-tube type membrane component is ensured to be suitable for treating wastewater with high turbidity and high sand content coefficient and adapt to severe water inlet conditions.

The disc tube type reverse osmosis component with the conventional structure has three problems at present, namely, a water inlet interface, a concentrated solution outlet and a permeate outlet of a membrane column component are arranged below or above a membrane column, when sewage enters a water inlet, the sewage needs to pass through a channel between a membrane shell and the outer edge of a flow guide disc and finally discharges water molecules and concentrated solution after turning back and passing through the surface of the flow guide disc, and the mode can form larger pressure in the membrane shell, easily accumulates gas in the shell and easily damages the flow guide disc; secondly, when water flows through, the pressure in the membrane shell enables the central pull rod to bear huge pulling force and be easy to break and damage, for the problem, the applicant has a patent with a patent number of 201920665415.9 which is filed as a novel disc tube type high pressure resistant membrane column utility model, but from the aspects of convenience of manufacture and installation and uniformity of stress, the innovation changes the structure that the central pull rod is integrally arranged in the membrane shell in the prior application, and the central pull rod is not subjected to internal pressure and is more uniformly stressed through the structure that the annular baffle nut is matched with the supporting piece; thirdly, the sealing between the adjacent guide discs is realized by matching O-shaped rings, and salient points are arranged on the surfaces of the guide discs, but the O-shaped rings are deviated due to stress in the mode, and the guide discs are weak and fragile in strength.

SUMMERY OF THE UTILITY MODEL

In order to overcome the technical defect, the utility model discloses a dish tubular reverse osmosis subassembly of individual soldier's outdoor use, including the membrane shell, be located the upper and lower flange at membrane shell both ends, upper and lower end cover is located a plurality of diaphragms and the flow guide disc of stack in proper order, runs through the central pull rod of diaphragm and flow guide disc, the interface of intaking, concentrate discharge port and see-through liquid discharge port set up into the water dish between lower flange and the central pull rod, the runner with the bottom flow guide disc contact is seted up to the dish of intaking, the runner intercommunication the interface of intaking, the concentrated liquid discharge port is seted up to the upper flange and the see-through liquid discharge port, the membrane shell both ends are installed upper and lower annular with the mode of screwing and are kept off female, install the support piece that thickness is greater than upper and lower end cover thickness between upper and lower annular fender female and the upper and lower flange.

Further, the utility model relates to a dish tubular reverse osmosis subassembly of outdoor use of individual soldier, the guiding plate is the rubber material, through the mode of moulding plastics at the peripheral annular flange that forms and a guiding plate body structure of guiding plate center round hole to form the strengthening rib structure on the guiding plate surface.

The invention has the following beneficial effects: 1. the membrane column assembly is integrally designed to feed water from the lower end of the membrane column assembly, produce water from the upper end of the membrane column assembly and discharge concentrated water from the upper end of the membrane column assembly, and the membrane column assembly has the advantages that raw water directly enters a system of a diversion disc and a membrane for turning back, so that the traditional situation that the raw water firstly passes through a membrane shell and then passes through the diversion disc is reduced, and the pressure intensity is effectively reduced; on the other hand, the exhaust is convenient, the danger of membrane damage caused by unsmooth exhaust is prevented 2, the central pull rod only has the function of penetrating and installing a flow guide disc, the action of tensile pull stress is avoided in the working engineering of the membrane column, and the annular retainer nut bears the pull force, so that the problem of pull fatigue fracture of the central pull rod is avoided; 3. the sealing between the flow guide disc and the flow guide disc breaks through the structure of the traditional flow guide disc and O-shaped ring assembly, and the problem of ring running is fundamentally solved by adopting an injection molding integrated structure. Finally, due to the comprehensive effect of the combination, the utility model can be applied to the treatment of various water sources, and has the effects of exquisite appearance and considerable water yield.
