Abstract
The invention discloses a bag filter which comprises a filtering barrel, a reinforcing net basket arranged in the filtering barrel, a filter bag fixed on the reinforcing net basket, and a feeding pipe and a discharging pipe which are arranged on the filtering barrel, wherein the feeding pipe is connected into the filter bag, the discharging pipe is arranged outside the filter bag, the filter bag comprises a plurality of filter bag units which are spaced up and down, areas of projective planes of the filter bag units are equal, and the projective planes are overlapped; and the feeding pipe is connected into the uppermost layer of filter bag unit. According to the invention, the filter bag is divided into a plurality of layers of filter bag units which are arranged up and down, so that filtering precision is improved, the volume is small, the structure is simple, and realization is easy.
Description
Technical field
The present invention relates to a kind of filter, be specifically related to a kind of bag filter.
Background technology
Bag filter is that a kind of novel structure, volume are little, convenient and flexible operation, energy-conservation, efficient, airtight work, multipurpose filter plant that applicability is strong.Bag filter is a kind of pressure type filter, mainly contain filtration barrel body, filtration barrel cover and fast opening mechanism, filter bag, stainless steel filter bag and strengthen the critical piece compositions such as basket, filtrate flows into filter bag by the side inlet tube of filter shell, filter bag itself is that device is in strengthening basket, the filter bag that Liquid Penetrant is crossed required fineness grade can obtain qualified filtrate, and impurity particle is tackled by filter bag.Bag filter in the middle of existing when carrying out fine filtering, adopts many bag type filterings usually, its complex structure, and equipment is huge, and cost is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, bag filter that filtering accuracy is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of bag filter, comprise filtration barrel body, be located at the reinforcement basket in the filtration barrel body and be fixed on the filter bag of strengthening on the basket, filtration barrel body is provided with feed pipe and discharge nozzle, wherein in the feed pipe access filter bag, discharge nozzle is arranged at outside the filter bag, described filter bag comprise between the upper and lower every a plurality of filter bags unit, the perspective plane area of each filter bag unit equates, and the perspective plane is overlapping; Described feed pipe accesses in the superiors filter bag unit.Filtered fluid enters from the superiors filter bag unit, and the filtration of structure multilayer filter bag unit its filtering accuracy is greatly improved, and its volume is little, simple in structure.
Preferably, described filter bag can be column structure, filter screen and the post jamb formation served as reasons and be connected with post jamb in each filter bag unit, and the perspective plane area of each filter bag unit equates with the cross-sectional area of filter bag.
Preferably, the cross section of described filter screen and filter bag can tilt crossing.
Preferably, described reinforcement basket can comprise housing and with a plurality of inside casings of filter bag units match, wherein housing is arranged at the filter bag outside, inside casing is arranged at below, filter bag unit.
In order to make the filter bag that is locked that housing can be more firm, described housing can be the net cylinder, and the outer surface of described filter bag is close to the inwall of net cylinder.
Be corroded in order to prevent filtration barrel body and to strengthen basket, described filtration barrel body and reinforcement basket are made by the organic synthesis material.
Compared with prior art, the present invention has the following advantages:
1, described filter bag is divided into the filter bag unit of the multilayer that is arranged above and below, and can improve filtering accuracy, and volume is little, and is simple in structure, is easy to realize;
2, the cross section of described filter screen and filter bag tilts to intersect, and has improved the filtering surface of filtrate, and then has improved filter efficiency;
3, described filtration barrel body and reinforcement basket are made by the organic synthesis material, can prevent from filtration barrel body and strengthen basket being had corrosive filtered fluid corrosion, prolong its service life.
