- Filtration Of Liquid (AREA)
Abstract
The utility model discloses a backwashing filter, which is an integral structure connected by two parts of shells, and a basin-shaped filtering net is assembled in one part of the shells, and a basin-shaped filtering net is assembled in one part of the shells. When washed, washing liquid is led in from a backwashing pipe on the upper part, and dirt and impurities are exhausted from a dirt drainage pipe on the lower part. A filter which is adopted to the structure has the characteristics of easy installation and convenient cleaning, and has the advantages of large effective filtering area and high filtering efficiency. The defects of easy filtering core blocking and bothersome exchange and washing of an old-fashioned filter are solved.
Description
The utility model belongs to a kind of filter, especially the backpulsing filter.
In the production process of modernized chemical enterprise, recommend the filter of use, greatly to there being three kinds, promptly " Y " type advances filter, steel right-angle type filter and conical filter, these several filters all are sixties designs, in the production practices of decades, brought into play important effect, but, also had higher requirement for chemical medium filters along with the develop rapidly of petrochemical technology, the filter of these several forms has been difficult to satisfy the requirement to filter plant of sophisticated equipment and technology, it is outstanding that some technical problems show especially, and effective filtration area is little, the fragile distortion of filter core, influence filter effect etc., therefore, the renewal of filter technology seems very urgent.
In addition, also have the Filter for pump that filters screen is housed in a kind of, obtained Patent Office and authorized, it is also by my design.
It is a kind of simple in structure that the purpose of this utility model is to provide, and effective filtration area is big, durable, all filters very easily of cleaning, replacing, blowdown are installed.The purpose of this utility model is achieved in that at one and basin shape screen pack is installed in by housing left part and housing right part housing dimerous, housing is to be left part flange and the right part flange structure that is connected in one by separately flange, basin shape screen pack places in the housing left part, housing left part left end is connected with inlet tube, top is connected with backwash tube, during operate as normal, medium enters the housing left part from inlet tube, behind basin shape screen pack, flow to the housing right part, flow out housing from the outlet bend pipe at last, after long-term the use, basin shape screen pack just need be done blowdown and handle, and at first is the MEDIA FLOW of breaking, and opens the valve on the blow-off pipe again, introduce from backwash tube with the high speed wash liquid stream, discharge from blow-off pipe, cleaning finishes just can recover to use, and also can take out basin shape screen pack in case of necessity and clean or change.
After adopting above technical scheme, the effective area of filtration obviously increases, and efficient obviously improves, and also is not easy blocking filter, cleans, installs, safeguards also very convenient.
The utility model will be further described below in conjunction with accompanying drawing and an embodiment.
Fig. 1 is the front view of backpulsing filter, and Fig. 2 is the front view of basin shape screen pack 13, and Fig. 3 is the right view of Fig. 2.
Following parts are arranged: 1 housing left part, 2 left part flanges, 3 backwash tubes, 4 backwash tube flanges, 5 outlet flanges among the figure, 6 outlet bend pipes, 7 housing right parts, 8 right part flanges, 9 blow-off pipes, 10 blow-off pipe flanges, 11 inlet tubes, 12 inlet tube flanges, 13 basin shape screen packs, 14 selvage pads.
In Fig. 1, omitted the another side flange that joins with each flange, and the pipe fitting that is connected such as valve, housing is made up of the two large divisions, that is: housing left part 1 and housing right part 7, left part flange 2 and 8 butt joints of right part flange by correspondence form, housing body is cylindric, all there is conical head at two ends, and housing left part 1 left end is connected with inlet tube 11 and inlet tube flange 12, and medium is entered in the housing by inlet tube 11, after being clipped in the basin shape screen pack 13 in left part flange 2 and the right part flange 8, after flowing to housing right part 7, flow in other pipelines or the equipment, finish filter process by outlet bend pipe 6.It is to be noted the structure of basin shape screen pack 13, its filtration fraction is the screen pack of basin shape, and the edge of net is a planar annular, relies on its basin shape screen pack 13 to be clipped in the middle of left part flange 2 and the right part flange 8.After long-term in addition the use, because the filtration of net, will be trapped in the housing left part 1 greater than impurity of screen distance etc., accumulate impurity when too much, just influence filter effect, the impurities removal blowdown of at this moment will stopping, the MEDIA FLOW of at first breaking, wash at a high speed from backwash tube 3 with cleaning fluid, foreign material etc. are discharged from blow-off pipe.Another kind of usage is with the conventional filtration device, and just at the filter net sheet in left part flange 2 and the suitable aperture of 8 folders of right part flange a slice, cleaning method is identical with said process, the utlity model has extensive applicability thus.
Claims (3)
1, a kind of backpulsing filter, it is by the screen pack that is assemblied in the housing, be connected the blow-off pipe under the housing, formations such as the import and export pipe at housing two ends, it is characterized in that: housing is formed by connecting by housing left part (1) and housing right part (7) two parts, and link into an integrated entity by each self-corresponding left part flange (2) and right part flange (8), basin shape screen pack (13) places in the housing left part (1).
2, a kind of backpulsing filter according to claim 1 is characterized in that: basin shape screen pack (13) is whole to be basin shape, and has a horizontal annular selvage pad (14); The left part flange (2) and the right part flange (8) of housing are clamped selvage pad (14), and basin shape screen pack (13) is positioned at housing left part (1).
3, a kind of backpulsing filter according to claim 1 is characterized in that: housing left part (1) left end is connected with inlet tube (11), and the bottom is connected with blow-off pipe (9); Housing right part (7) right-hand member is connected with outlet bend pipe (6), and top is connected with backwash tube (3).
