Abstract
The utility model discloses a hollow fiber filter device with external pressure pipe comprising a shell, a filter cartridge arranged inside the shell, a water inlet, an air inlet and a water outlet arranged on the shell, wherein two ends of the filter cartridge and the shell are detachably sealed. The detachability of the filter cartridge results in that compressed air is evenly blown into a plurality of membrane filaments and resin layer root, and sufficient air vibration and air bubble scrubbing are processed on the outer surface of the membrane filaments to proceed pipeline cleaning, thereby the penetration quantity of the filter liquid is recovered quickly, and a continuous filtering is achieved. The filter cartridge which is detachable from the shell is capable of being cleaned physically and chemically and maintained, and a backward cleaning is achieved, thereby the durability of a water processing machine is improved which results in convenience and economy. The air inlet and the water inlet separation is achieved through the detachable structure of the shell and the filter cartridge, and under the same condition, more water processing quantity is achieved through the water outlet on the top cover of two ends of the filter.

In above-mentioned external pressure tubular type hollow fiber filter device, stay pipe plays the fixedly film base effect of casting of easy for installation, length location and structure to filter core.
In above-mentioned external pressure tubular type hollow fiber filter device, in order to realize reverse cleaning, water inlet pipe is separated with air inlet pipe, water inlet and air inlet are located at respectively on the shell side, and delivery port is located on the shell end face.
In above-mentioned external pressure tubular type hollow fiber filter device, for convenient dismounting, the two ends of shell are provided with top cover detachable and that be sealed and matched, and delivery port is located on the top cover.
In above-mentioned external pressure tubular type hollow fiber filter device, in order to blast compressed air evenly distributedly from the root of film silk, film silk outer wall is carried out sufficient air vibration and bubble scouring, thereby improve the effect of filtering, the structure of shell can be designed to: be made up of two packing elements and middle sleeve, two packing elements are connected with the sealed at both ends of sleeve respectively, and water inlet and air inlet are located on the packing element side.Proper design is: a packing element side is provided with water inlet and air inlet, also is provided with water inlet and air inlet on another packing element side.
In above-mentioned external pressure tubular type hollow fiber filter device, for the better removable seal of top cover and shell of realizing cooperates, top cover can be connected or the clip clamping by bolt flange with shell.
In above-mentioned external pressure tubular type hollow fiber filter device,, top cover can be designed to the concave structure of falling the bridge arch in order to make top cover can play the effect of the free degree that limits filter core.
Compared with prior art, the utlity model has following beneficial effect:
1. filter core detachable can realize blasting compressed air evenly distributedly, the outer wall of film silk being carried out sufficient air vibration and bubble scouring from some film silks and resin bed root, carries out on-line cleaning, recovers the filtrate transit dose rapidly, realizes online continuous filtration.
2. detachably the make production and the detection of filter core are not limited by local space, and simple and compact for structure, production technology realizes easily, enhances productivity effectively.
3. the detachable of filter core can convenient the taking-up be carried out physical chemistry cleaning, maintenance from shell, can also realize reverse cleaning, thereby improve the life-span of hydrotreater, and be not only convenient but also economical.
4. shell realizes that with the split-type structural of filter core admission line separates with inlet channel, and water inlet on the two packing element sides and two ends top cover upper water-out mouth can act on simultaneously, realize bigger raising water treatment amount under the equal conditions.
