Description
Technical field
the utility model relates torO water machine system equipment
field, especially a kind of RO membrane cartridge reverse-osmosis filtering device with constant temperature current.
Background technology
RO(Reverse Osmosis) i.e. reverse osmosis technology, use cost along with the extensively universal RO water machine of RO water machine also causes the attention of people gradually, the replacement cost of " waste water " that this cost wherein produces while being just included in and obtaining pure water and filter membrane especially RO film, affect this two be efficiency and service life of RO film after all.Affect RO membrane lifetime because have the contents of residual chlorine in a lot of such as water, the pH value of water, intake pressure, temperature etc., wherein the impact of this factor of temperature on RO film also can not be ignored.Temperature is too high or too lowly all can affect the product water efficiency of RO film and the service life of RO film.Reverse osmosis membrane is organic film, also meets and expands with heat and contract with cold, and temperature is high, will expand, can improve the permeable amount of water.But the hydrolysis rate of organic film is relevant with temperature, temperature is more high to be more easily hydrolyzed.So the permeable amount of reverse osmosis membrane is increasing and increase with water temperature, also can accelerate the hydrolysis rate of film simultaneously, and make organic film deliquescing, be easy to compacting, the rising of water inlet water temperature can cause the increase of desalination rate and the decline of salt rejection rate equally, and this is mainly because salinity accelerates the service time that so will reduce RO film through the raising of the diffusion velocity meeting Yin Wendu of film.Temperature is low, and the attribute of RO film determines its aquifer yield can be reduced with the decline of water temperature.Usual RO film is when water temperature 25 degree, and former water use efficiency recommendation is 15%; And when water temperature often once declines, RO film aquifer yield can corresponding decline 3%; When water temperature is down to 8 degree, its aquifer yield has declined more than 50%, and its former water use efficiency also can decline 50%, therefore when inflow temperature is too low, the discharge capacity thing of waste water is very surprising.It should be noted that the different maximum temperature minimum temperatures required by film manufacturer and optimal temperature are different, and existing RO water machine is not containing fast heating function.
Summary of the invention
for the problems referred to above, the utility model aims to provide a kind of RO membrane cartridge reverse-osmosis filtering device with constant temperature current.
for realizing this technical purpose, scheme of the present utility model is: a kind of RO membrane cartridge reverse-osmosis filtering device with constant temperature currentcomprise device water inlet, device delivery port, the first water flow switch, the second water flow switch, thermostatic chamber, the first DC heating rod, the second DC heating rod, temperature sensor, temperature controller and package casing, be connected with the first water flow switch, thermostatic chamber and the second water flow switch between described device water inlet and device delivery port in turn, the first DC heating rod above described thermostatic chamber is connected with temperature controller by wire with the second DC heating rod and temperature sensor; Described temperature controller is arranged on package casing, and temperature controller is provided with temperature controller guidance panel.
As preferably, described device water inlet and device delivery port run through package casing, and water supply connector and water out adapter can be positioned at the two ends of shell or be fixed on one end of shell by pipeline.
As preferably, described package casing is cylindrical structure or cube structure, and described package casing material is high-temperature resistance plastice.
As preferably, described temperature controller is direct current temperature controller, and direct current temperature controller can replace by temperature-adjusting circuit structure.

Accompanying drawing explanation
fig. 1 is that this practicality is newthe structural representation of type.
Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, a kind of RO membrane cartridge reverse-osmosis filtering device with constant temperature current of the utility model embodiment, comprise device water inlet 1, device delivery port 2, first water flow switch 3, second water flow switch 4, thermostatic chamber 5, first DC heating rod 6, second DC heating rod 7, temperature sensor 8, temperature controller 9 and package casing 10, the first water flow switch 3 is connected with in turn between described device water inlet 1 and device delivery port 2, thermostatic chamber 5 and the second water flow switch 4, the first DC heating rod 6 above described thermostatic chamber 5 is connected with temperature controller 9 by wire with the second DC heating rod 7 and temperature sensor 8, described temperature controller 9 is arranged on package casing 10, and temperature controller 9 is provided with temperature controller guidance panel.
As preferably, described device water inlet 1 and device delivery port 2 run through package casing 10, and water supply connector and water out adapter can be positioned at the two ends of shell or be fixed on one end of shell by pipeline.
As preferably, described package casing 10 is cylindrical structure or cube structure, and described package casing 10 material is high-temperature resistance plastice.
As preferably, described temperature controller 9 is direct current temperature controller, and direct current temperature controller can replace by temperature-adjusting circuit structure.
As preferably, in described first water flow switch 3 and the second water flow switch 4 cooperation detection water route, whether there is current flowing.
As preferably, described thermostatic chamber 5 is encapsulated by stainless steel material and forms, and thermostatic chamber 5 is provided with into water connector, water outlet connector, interface placed by temperature sensor and interface placed by heating rod.
