Description
Technical field
The utility model relates to the backwash filter in a kind of water treatment aeration filter tank, especially relates to a kind of pre-buried expansion type interchangeable backwash filter of exempting from.
Background technology
Filtration is an important step in the water treatment technology, when the filter tank is moved, increase along with the filter material layer holding filth capacity, the mud infiltration capacity is deepened, and causes filtering velocity to descend, and the filter tank resistance just rises gradually, filter back water turbidity raises, for making the filter tank recover normal operation, guarantee effluent characteristics and water outlet efficient, just must carry out backwash to the filter tank.At present, the backwash filter structure kind that is used for filter back washing is a lot, have block-proof type, adjustable etc.But they all adopt on filter plate some backwash filters are set at interval, backwash are carried out in the filter tank from bottom to top by the mode that the filter water that is interspersed and/or gas crosswise jet distribute.But which kind of structure existing backwash filter no matter be, they all have a common ground is exactly that to be used for fixing the filter bar cover of filtering bar all be to require and be embedded at interval in the filter plate that armored concrete makes according to backwashing technology in the filter tank, though filter bar cover is fixing very firm in filter plate, but there is following point in pre-buried filter bar cover: the one, because the needs of built-in fitting, existing filter plate adopts first piecemeal to make, transport to the filter tank again and carry out spelling, with briquetting and screw rod filter plate is fixed again, though it is pre-buried more convenient to adopt piecemeal to make and filter the bar cover, but it is big to make its filter plate freight volume of filter plate like this, the piecemeal spelling is installed trouble, the labour intensity height, work time cost is many, and briquetting and screw rod consumption are big, and cost improves; The 2nd, the filter bar is enclosed within the pre-buried process, and cement mortar is easy to flow on the filter bar cover internal thread, sticks to easily after cement mortar solidifies in the internal thread groove of filter bar cover, causes the screw thread fracture of wire, cause filtering bar stuck, difficulty is installed even can not installs; If the filter bar is installed by force, will damage filter bar cover and filter bar, cause the backwash filter vacancy to occur, finally cause backwash gas water layer skewness, thereby reduce water outlet efficient and effluent characteristics, if filter bar cover internal thread is cleared up, because backwash filter quantity is many on the whole filter plate, thereby the cleaning work amount is big, the labour intensity height; Be that the filter bar is enclosed within the pre-buried process again, some filter bar cover angle of inclination is excessive, causes filter bar installation difficulty or filter bar to tilt, and causes backwash gas water layer skewness, can influence water outlet efficient and effluent characteristics equally.
The utility model content
At above-mentioned problems of the prior art, the utility model provides a kind of convenience not only quick for installation, and installation quality is good, and water outlet efficient height, and effluent characteristics is good again exempts from pre-buried expansion type interchangeable backwash filter.
The technical scheme that the technical problems to be solved in the utility model is taked is: describedly exempt from pre-buried expansion type interchangeable backwash filter it comprises into water filter cap, the filter bar, water outlet filter cap and filter bar cover, filter bar set upper side links to each other with water outlet filter cap, water outlet filter cap and filter plate contact-making surface are provided with sealing gasket, the middle part is connected with the filter bar with screw thread in the filter bar cover, filter bar lower end is connected with water inlet filter cap, be provided with air admission hole and air inlet duct at filter bar hypomere, filter bar set upper side is provided with cone-shaped flange, filter bar cover lower end is passed filter plate and is fitted with nut, filter bar cover is provided with expansion sleeve, and the expansion sleeve upper end has open slot and can outwards be stretched over filter plate inside on it under the stubborn power effect of nut.
The utility model sets out and filters earlier the corresponding shoulder hole spaced apart of bar cover outer shape on filter plate, be not filled on the filter plate and will not filter pre-buried the watering of bar cover earlier.When the backwash filter is installed, to filter the bar cover earlier and put into prior prefabricated shoulder hole on the filter plate from bottom to up, again water outlet is filtered cap and filter bar cover sealing and fixing, to filter again in the bar insertion filter bar cover and fix and adjust filter bar height with screw thread, fastening nut, nut make the upper end of expansion sleeve band open slot outwards be stretched over filter plate inside to the expansion sleeve application of force, form the turbination that outwards scatters, thereby filter bar cover can be fixed in the filter plate.
The utility model is as long as carry out reserving when armored concrete is whole to be watered shoulder hole at the construction field (site), carry out pre-buried and will not filter the bar cover, do not need to make up with transporting to the job site again after the piecemeal pouring, transportation and installation workload both can have been reduced, save work time cost, transposing is installed conveniently, save briquetting and screw rod auxiliary material, reduce the mounting material cost, the laborsaving expense of economizing again; Be to avoid pre-buried filter bar cover and the problem that adheres to cement slurry in the filter bar cover internal thread groove that brings again, can improve the installation effectiveness and the installation quality of backwash filter again, reduce installation cost, improve water treatment efficiency and effluent characteristics.
Described filter bar, filter bar cover, water outlet filter cap and water inlet filter cap all adopt the manufacturing of ABS engineering plastics, and its hot strength is that 21-28MPa, impact strength are 27-49kg/cm
2, the bearing strength height is stepped on and is bumped not brokenly, and sealing gasket adopts the nontoxic rubber manufacturing, and expansion sleeve adopts intensity and good engineering plastics or the metal material manufacturing of plasticity.
