Runner rotating valve is connected.
System automatic valve is few, fault rate is low, compact-sized, on-line filtration area is big, floor space is small, continuous operating time
It is long.
Next, the automatic back-washing filtration system is described in detail by some specific embodiments：
A kind of automatic back-washing filtration system, such as Fig. 1,2, it is shown, include the filter of three more parallels, all mistakes
The import of filter 2 is connected with the first multiple flow passages rotary valve 1, and the outlet of all filters 2 rotates with the second multiple flow passages
Valve 5 is connected；
First multiple flow passages rotary valve 1 and the second multiple flow passages rotary valve 5 are multidigit two-way valve, are equipped with 1 material
Total mouth, multiple distribution openings and 1 connected entrance, inside are equipped with rotatable valve element, and the distribution openings and the filter 2 are one by one
It is corresponding；
Also include central controller 3, the central controller 3 respectively with the first multiple flow passages rotary valve 1, described second
Multiple flow passages rotary valve 5 is connected.
The first multiple flow passages rotary valve 1, the second multiple flow passages rotary valve 5 are controlled by central controller 3.
During system operation, the first multiple flow passages rotary valve 1, the synchronous rotary of the second multiple flow passages rotary valve 5, when valve position is rotated to certain
During one distribution openings, the distribution openings and connected entrance communicate, and corresponding filter 2 forms an independent path, the group together
Filter 2 is individually switched out from system, in off-line state.
Offline filter 2 can be backwashed, soaked, medium displacement or be safeguarded, liquid, auxiliary after filter can be used during backwash
Gas or other liquid are cleaned, and make filter element cleaning more thorough, regeneration effect is more preferable.
The total mouth of material of the first multiple flow passages rotary valve 1 is connected with filtrate medium inlet；The first multiple flow passages rotation
The distribution openings of valve 1 are connected with the corresponding filter 2 respectively；The connected entrance and dreg slurry of the first multiple flow passages rotary valve 1
Outlet is connected；
The total mouth of material of the second multiple flow passages rotary valve 5 is connected with media outlet after filter, the second multiple flow passages rotation
The distribution openings of valve 5 are connected with the corresponding filter 2 respectively.
The connected entrance of the first multiple flow passages rotary valve 1 is connected with replacement media entrance, immersion medium inlet；
The connected entrance of the second multiple flow passages rotary valve 5 is connected with replacement media outlet, standby mouth, drain.Can basis
The characteristic selection immersion of medium and the mode of displacement, strengthen backwash effect.
Media outlet after the filter, the blowback medium inlet, the drain, the filtrate medium inlet, described put
Change medium inlet, it is described immersion medium inlet, the dreg slurry outlet be respectively equipped with autocontrol valve 4.
All autocontrol valves 4 are connected with the central controller 3 respectively.By central controller 3 to each automatic
Control valve 4 is controlled.
The number of the filter 2 is any natural number in 4-10.
Filter core is provided with the filter 2, filter core is following any：Woven wire filter core, porous ceramic filter element, wedge shape

This automatic back-washing filtration system uses mechanically decoupled principle, will contain solid medium using the filter core of well-designed manufacture
Solid matter in (solid-liquid mixing) is separated.N set filter operational modes, when one of filter is off-line state,
Remaining N-1 set filter carries out filter operation online, and the medium containing solid material flows through N-1 set filters, and particulate matter gradually sinks
Accumulate and be gathered in filter core exterior surface area and form filter cake, as filter cake thickness increases, liquid stream is increasingly difficult to through filter core, pressure difference
Increase, when pressure difference reach preset value or filtration time reach preset the time when, the rotation of central controller controls multiple flow passages
Rotary valve, makes the filter on-line running of off-line state, while makes that online wherein 1 set filter is offline, and offline filter is opened
Beginning backwash or immersion, displacement, maintenance, automatic back-washing filtration system to be cut after terminating again and is filtered, this process is closed procedure,
Remaining each filter repeats above-mentioned action and carried out one by one successively, up to last 1 set filter backwash or immersion, displacement, has safeguarded
It is stand-by after finishing.Switching between filter is realized by multiple flow passages rotary valve, is controlled by control system, is realized whole automatic anti-
Wash the full automatic working of filtration system.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
