Description
Technical field
The utility model relates to water-treatment technology field, is specially a kind of water purifier reverse osmosis membrane unit possessing Automatic adjusument function.
Background technology
In the various experimentations in laboratory, usually all need to use purified water, common reverse osmosis membrane drinking water purification process is one of technique the most general of purifier employing in the market.Removing by arranging reverse osmosis membrane apparatus on water route the various poisonous and harmful substances wherein existed, making water supply quality relevant criterion.
In general, conventional reverse osmosis membrane apparatus includes reverse-osmosis membrane element, needing, multiple reverse osmosis membrane unit is set and could realize repeatedly counter-infiltration, reverse osmosis membrane unit in use, treating capacity in unit interval is fixing, the excessive water purification quality easily having influence on filter core and reverse osmosis membrane of water inlet discharge, also easily results in blockage simultaneously, causes the penetrating amount of film to decline; Water inlet discharge is too small, easily has influence on the unit interval water yield of device, and then directly has influence on cleaning water.
Utility model content
The technical problem that the utility model solves is to provide a kind of water purifier reverse osmosis membrane unit, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of water purifier reverse osmosis membrane unit, it is a long tubular structure, comprise interior pipe and outer tube, wherein, interior pipe is arranged in outer tube, jointly forms with outer tube the piston structure that is with negative pressure cavity, described outer tube is provided with water inlet, this water inlet connects negative pressure cavity, described interior pipe top drilling, and communicates with negative pressure cavity at position of opening; In addition, also include in interior pipe and interior pipe is separated into mutual disconnected two-part collector pipe, described collector pipe closed upper part and from interior pipe top drilling 50 ~ 80mm, collector pipe outer wall is set with filter core, and form one deck reverse osmosis membrane on filter core outer wall, and collector pipe has the permeable hole for the pure water after receiving purification on the tube wall of filter core section.
In the utility model, described filter core is columnar ceramic material filter element or column resin material filter core.
In the utility model, the delivery port of reverse osmosis membrane unit is two, comprises the pure water outlet be arranged on interior pipe bottom surface and the dense water out be arranged on bottom interior pipe on sidewall.
In the utility model, the bottom of described interior pipe is provided with a cushion chamber, for cushioning water body pressure.
Beneficial effect: the utility model is provided with negative pressure cavity and piston unit in reverse osmosis units, by the acting in conjunction of negative pressure cavity and piston unit, can when reverse osmosis units uses according to the clean water treatment amount of the discharge Automatic adjusument reverse osmosis units of water inlet, effectively improve water rate processed, improve pH value and the water purification quality of water outlet, and effectively can extend the service life of reverse osmosis units.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: 1, water inlet; 2, negative pressure cavity; 3, outer tube; 4, end cap; 5, interior pipe; 6, ceramic element; 7, collector pipe; 8, reverse osmosis membrane; 9, cushion chamber; 10, dense water out; 11, pure water outlet.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment of a kind of water purifier reverse osmosis membrane unit of Fig. 1, in the present embodiment, reverse osmosis membrane unit is the assembled casing structure of an elongated tubular, comprise interior pipe 5 and outer tube 3, wherein, the top of outer tube 3 is provided with water inlet 1, and this water inlet 1 rear portion is connected to the negative pressure cavity 2 vacated between outer tube 3 and interior pipe 5.
Interior pipe 5 is positioned at negative pressure cavity 2 bottom of outer tube 3, and at the top drilling of interior pipe 5, and 50mm position, position of opening bottom is provided with a collector pipe 7, interior pipe 5 be divide into two parts of Hu Bu UNICOM by collector pipe 7.Collector pipe 7 top is closed by end cap 4, and on the outer wall of body epimere, be set with the ceramic element 6 of column, and the outer wall of ceramic element 6 then forms one deck reverse osmosis membrane 8.Then be arranged in a cavity structure as cushion chamber 9 at the body hypomere of collector pipe 7, interior pipe 5 is other in this cavity structure side is provided with a dense water out 10 that can control voluntarily to carry out opening and closing.In addition, pure water outlet 11 is then directly connected at the end of collector pipe 7.
The present embodiment in use, intake by water inlet 1, first water to be clean gather after entering unit in negative pressure cavity 2, then interior pipe 5 is entered by the perforate at interior pipe 5 top, and outside the ceramic element 6 and reverse osmosis membrane 8 of interior pipe 5 and gather in cushion chamber 9, meanwhile, ceramic element 6 and reverse osmosis membrane 8 start to carry out water purification diafiltration, water after diafiltration is entered in collector pipe 7 by the permeable hole on collector pipe 7, and exports pure water eventually through the pure water outlet 11 bottom collector pipe 7.In the process, dense water out 10 is in closed state, when fluctuation appears in the inflow of water inlet 1, the piston structure be jointly made up of interior pipe 5 and outer tube 3 and negative pressure cavity 3 acting in conjunction, in order to ensure that the constant voltage in reverse osmosis membrane unit comes counter-infiltration effect and the efficiency of stable reverse osmosis membrane 8.And when the water body concentration in interior pipe 5 reaches critical value or in reverse osmosis membrane unit hydraulic pressure too high cannot from line stabilization time, all carry out drain operation to ensure the stability of equipment by opening dense water out 10.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
