Abstract
The utility model relates to an exterior pressure type hyperfiltration water purifier, which comprises a casing and a hollow fiber filter cartridge arranged in the casing, wherein the casing consists of a cylinder body, a left end cover and a right end cover; the hollow fiber filter cartridge is arranged in the cylinder body through a positioning sealing component; the left end cover and the right end cover are hermetically connected with the cylinder body respectively through fastening rings; a pure water outlet is formed on the left end cover; a tap water inlet and a dirt discharge hole are formed on the side wall of the cylinder body; a backwashing hole is formed on the right end cover; and the backwashing hole is provided with a backwashing water inlet and a backwashing dirt discharge hole through a tee joint. Because a device for backwashing the hollow fiber filter cartridge is arranged in the water purifier, dirt adhering to or blocked in a hole of the hollow fiber filter cartridge can be washed away so as to keep the purification efficiency and the purification effect of the hyperfiltration water purifier with the hollow fiber filter cartridge, and effectively prolong the service life of the hollow fiber filter cartridge. The utility model has the advantages of simple and reasonable structure, convenient and easy backwashing operation, good purification effect and the like.
Description
Technical field:
The utility model relates to the water purifier technical field, specifically is a kind of external-compression type doughnut filter core ultra-filtration water purifier.
Background technology:
With the water purifier of doughnut filter core as filter element, mainly constitute by shell and the doughnut filter core that is arranged at wherein, on the wall of shell, be provided with the running water water inlet, purify waste water delivery port and flushing pollution discharge mouth, existing Hollow Fiber Ultrafiltration water purifier, be divided into two kinds of external-compression type and inner presseds, no matter but be external-compression type or inner pressed, water purifier inside will be divided into by the doughnut filter core and purify pool and pool from the beginning, when water purifier is implemented flushing, only pool is from the beginning washed, can't wash the dirt that adheres to or be jammed in doughnut filter core filter opening, along with the accumulation of time, the purification efficiency and the clean-up effect of doughnut filter core ultra-filtration water purifier will constantly descend, and stop up fully and scrap until the doughnut filter core.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming of existing Hollow Fiber Ultrafiltration water purifier, provide a kind of can be to adhering to or being jammed in the external-compression type ultra-filtration water purifier that the dirt of doughnut filter core filter opening washes, with the purification efficiency and the clean-up effect of maintenance doughnut filter core ultra-filtration water purifier, thus the service life of improving the doughnut filter core.
The utility model, comprise housing and the doughnut filter core that is arranged at wherein, housing is made up of cylindrical shell, left end cap and right end cap, and the doughnut filter core is installed in inner barrel by positioning seals, left end cap and right end cap are tightly connected by dead ring and cylindrical shell respectively, on left end cap, be provided with pure water inlet, on the sidewall of cylindrical shell, be provided with running water water inlet and sewage draining exit, on right end cap, be provided with the backwash mouth, the backwash mouth is provided with backwash water inlet and sewage backwash mouth by threeway.
The utility model, described pure water inlet, sewage draining exit and sewage backwash mouth are equipped with water valve, and the running water water inlet is connected running water by water valve respectively with the backwash water inlet.
The utility model, owing in water purifier, be provided with to doughnut filter core back purge system, can wash the dirt that adheres to or be jammed in the doughnut filter core filter opening, to keep the purification efficiency and the clean-up effect of doughnut filter core ultra-filtration water purifier, effectively improve the service life of doughnut filter core, and have simple and reasonablely, backwash operation is convenient and easy, advantages such as good purification.
Description of drawings:
Fig. 1 is the structural principle cutaway view of embodiment.
Among the figure, 1, cylindrical shell 2, doughnut filter core 3, left end cap 4, dead ring 5, pure water inlet 6, sewage draining exit 7, running water water inlet 8, right end cap 9, backwash mouth 10, backwash water inlet 11, recoil sewage draining exit 12, positioning seals.
The specific embodiment:
With reference to Fig. 1, this external-compression type ultra-filtration water purifier, comprise housing and the doughnut filter core 2 that is arranged at wherein, housing is by cylindrical shell 1, left end cap 3 and right end cap 8 are formed, doughnut filter core 2 is installed in inner barrel by the positioning seals 12 at its two ends, left end cap 3 and right end cap 8 are tightly connected by dead ring 4 and cylindrical shell 1 respectively, on left end cap 3, be provided with pure water inlet 5, on the sidewall of cylindrical shell 1, be provided with running water water inlet 7 and sewage draining exit 6, on right end cap 8, be provided with backwash mouth 9, backwash mouth 9 is provided with backwash water inlet 10 and sewage backwash mouth 11 by threeway.
When using this external-compression type ultra-filtration water purifier, will water valve be set respectively at pure water inlet 5, sewage draining exit 6 and sewage backwash mouth 11, running water water inlet 7 is connected running water by water valve respectively with backwash water inlet 10.
Its course of work is: (1) operation of purifying waste water: close the water valve on sewage draining exit 6, backwash water inlet 10 and the sewage backwash mouth 11, open the water valve on running water water inlet 7 and the pure water inlet 5, running water is under the effect of hydraulic pressure, clean water is penetrated into the inboard from the outside of doughnut filter core 2, compiles the back at the left end cap place and flows out from pure water inlet 5.At ordinary times, can open the water valve on the sewage draining exit 6, the water that flows out from sewage draining exit 6 can be used for the non-domestic water of drinking, and like this, both using water wisely are carried out regular cleaning to the pool from the beginning of water purifier again; (2) backwash operation: a, close the water valve on pure water inlet 5, sewage backwash mouth 11 and the running water water inlet 7, open the water valve on sewage draining exit 6 and the backwash water inlet 10, under the effect of hydraulic pressure, running water flows to the outside from the inboard of doughnut filter core 2, under the effect of tap water pressure, the dirt that adheres to or be jammed in doughnut filter core filter opening is washed, and dirt flows out from sewage draining exit 6 with current, and the time of backwash and frequency be control flexibly according to circumstances; B, close the water valve on backwash water inlet 10 and the sewage draining exit 6, open the water valve on sewage backwash mouth 11 and the running water water inlet 7, allow the running water in the doughnut filter core discharge from sewage backwash mouth 11, simultaneously, also allow purifying waste water of doughnut filter element filtering wash the inwall of doughnut filter core, the time of keeping can be grasped flexibly, at last, close the water valve of sewage backwash mouth 11, open the water valve of pure water inlet 5, the work of just can purifying waste water normally.
