Description
Technical Field
The utility model relates to a sewage purification field especially relates to a reverse osmosis membrane shell.
Background
With the improvement of living standard, the water purifier is in explosive growth in China. However, the water purifier is expensive and is very popular with consumers. The water purifier is high in price and is closely related to the cost of parts of the water purifier. Wherein the price of the waste water electromagnetic valve is an important factor influencing the cost of the water purifier. Meanwhile, the cost of the water purifier is increased by adding one part. Therefore, the reverse osmosis membrane shell capable of adjusting the flow of the wastewater is developed, the use of wastewater electromagnetic valves can be reduced, and the cost of the water purifier is greatly reduced.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the invention provides the reverse osmosis membrane shell with the adjustable wastewater flow, and the wastewater valve is simply integrated on the reverse osmosis membrane shell, so that the part cost of the water purifier can be greatly reduced, and the space of the water purifier is saved.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
a reverse osmosis membrane shell capable of adjusting waste water flow comprises a membrane shell body, a pure water port and a concentrated water port, wherein the pure water port and the concentrated water port are arranged at one end of the membrane shell body; the driving wheel and the fixed wheel are both provided with through crescent holes as flushing ports. The fixed wheel adopts an open cavity structure to collect concentrated water and discharges the concentrated water through the crescent holes.
Preferably, the movable wheel and the fixed wheel are assembled by a rotating shaft.
Preferably, a large sealing ring is arranged at the edge of the driving wheel, a corresponding closed groove is correspondingly formed in the position of the fixed wheel and used for assembling the large sealing ring, a small sealing ring is arranged in the middle of the fixed wheel, and a corresponding closed groove is correspondingly formed in the position of the driving wheel and used for assembling the small sealing ring.
Preferably, the lower part of the movable wheel is fixed by a positioning clamp so as to prevent the movable wheel and the fixed wheel from being not tightly jointed.
The realization mode is as follows: the reverse osmosis concentrated water is discharged through concentrated water holes in the middle of the fixed wheel and the movable wheel, and the pressure in the membrane shell is higher due to the smaller concentrated water hole ratio, so that the normal water production stage is realized; when the water-saving washing machine runs for a period of time, the fixed wheel is rotated for a certain position, when the crescent holes of the fixed wheel and the movable wheel are superposed, the waste water can flow out through the crescent holes, the water distribution discharge amount is increased, the membrane surface flow rate is increased, and the washing stage is performed at the moment; therefore, the water discharging amount can be increased by rotating the driving wheel in the washing stage, and the washing is facilitated, so that the use of a waste water electromagnetic valve can be reduced, and the cost of the water purifier is reduced. And because the fixed wheel and the driving wheel adopt a tight attaching mode, and the periphery is provided with a double-layer sealing ring for sealing, the concentrated water can be effectively prevented from flowing out through the middle gap, and the water leakage risk is effectively solved.

Detailed Description
The present invention will be further described with reference to fig. 1 to 4.
Examples
As shown in fig. 1 to 4, an adjustable wastewater flow reverse osmosis membrane shell comprises a membrane shell body 1, a concentrate port 2 and a pure water port 3 which are arranged at one end of the membrane shell body, wherein the concentrate port 2 is provided with a fixed wheel 22, the fixed wheel is a cylinder, the upper end of the fixed wheel is provided with a cavity, the fixed wheel and the membrane shell body are integrally arranged, the outer side of the fixed wheel 22 is provided with a driving wheel 21 which is concentric with the fixed wheel 22, the driving wheel 21 and the fixed wheel 22 are assembled through a rotating shaft, and the centers of the driving wheel and the fixed wheel are penetrated by a hollow thin tube (211,221) to be used as a concentrate port; both the driving wheel 21 and the fixed wheel 22 are provided with through crescent holes (213,223) as flushing ports; the fixed wheel 22 adopts an open cavity structure 224 for collecting concentrated water and discharging the concentrated water through the crescent holes; a large sealing ring 215 is arranged at the edge of the driving wheel 21, a corresponding sealing groove 224 is correspondingly arranged at the position of the fixed wheel 22 for assembling the large sealing ring, a small sealing ring 225 is arranged at the middle position of the fixed wheel 22, and a corresponding sealing groove 224 is correspondingly arranged at the position of the driving wheel 21 for assembling the small sealing ring; and a positioning clamp 4 is used for fixing the lower part of the driving wheel, so that the driving wheel and the fixed wheel are prevented from being not tightly attached.
