Description
Technical field
The invention belongs to intermetallic composite coating cooling fluid secondary filter process field, be specifically related to a kind of high accuracy bypass-filtering device.
Background technology
Filtering technique conventional is at present mainly gravity filter, centrifugal filtration, external force aided filter, biofiltration etc., but major part filters to exist to be needed to regularly replace consumptive material, cost is high, filtering accuracy is low problem, it is that the impurity being attached to filter media surface needs periodic cleaning that no material consumption filters subject matter, and conventional method is labor cleaning, more loaded down with trivial details and lose time, filtering accuracy is high, no material consumption the filter method of Automatic clearance can become a kind of development trend of filtration again, is subject to the popular welcome of user.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high accuracy bypass-filtering device, the invention provides the filter type that a kind of filtering accuracy reaches 1 μm, solving conventional fine filter method can not the problem of Automatic clearance, realizes no material consumption and filters.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of high accuracy bypass-filtering device:
Comprise central tube, upper guard-plate, lower end-stopping plate, it is characterized in that, also comprise filter paper and tensioning spring, described central tube is hollow thin-wall pipe, and the tube wall of described central tube has equidistant axial slits; Described central tube comprises upper and lower two parts, described central upper portion pipe is connected by described tensioning spring with described lower central pipe, by the described central tube that stretches, described tensioning spring is compressed, the reaction force of described tensioning spring makes filter paper lamella and layer fit tightly; Described filter paper is annular, is arranged on described central tube by stacked mode, forms the medium filtered; Described central upper portion pipe arranges described upper guard-plate, and described lower central pipe arranges described lower end-stopping plate, and described upper guard-plate is fixed dam, and described lower end-stopping plate is sideboard.Stacked filter paper is fixed in the middle of upper guard-plate and lower end-stopping plate.
Further, described lower central pipe 4 has the top ends that diameter is less than described central tube diameter, and it stretches in described central upper portion pipe 2, arranges extension in the upper end of top ends, space is formed, with accommodating tensioning spring 3 between extension and described central upper portion pipe 2.
Further, the thickness of described filter paper is 0.01mm.
Further, the stacked number being layered in the filter paper on described central tube at least wants thousand layers.
Further, described upper guard-plate is fixed dam, and described lower end-stopping plate is sideboard.
Beneficial effect of the present invention is:
1) filter type of a kind of high accuracy (filtering accuracy reaches 1 μm) is provided;
2) solving conventional fine filter method can not the problem of Automatic clearance, realizes no material consumption and filters.

Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with drawings and embodiments, the present invention is described in further detail.
Composition graphs 1 and Fig. 2, a kind of high accuracy bypass-filtering device: comprise central tube, upper guard-plate 5, lower end-stopping plate 6, it is characterized in that, also comprise filter paper 1 and tensioning spring 3, described central tube is hollow thin-wall pipe, and the tube wall of described central tube has equidistant axial slits 7; Described central tube comprises upper and lower two parts, described central upper portion pipe 2 is connected by described tensioning spring 3 with described lower central pipe 4, by the described central tube that stretches, described tensioning spring 3 is compressed, the reaction force of described tensioning spring 3 makes filter paper 1 layer and layer fit tightly; Described filter paper 1 is annular, is arranged on described central tube by stacked mode, forms the medium filtered; Described central upper portion pipe 2 arranges described upper guard-plate 5, and described lower central pipe 4 arranges described lower end-stopping plate 6, and described upper guard-plate 5 is fixed dam, and described lower end-stopping plate 6 is sideboard.Stacked filter paper is fixed in the middle of upper guard-plate 5 and lower end-stopping plate 6.
Described lower central pipe 4 has the top ends that diameter is less than described central tube diameter, and it stretches in described central upper portion pipe 2, arranges extension in the upper end of top ends, between extension and described central upper portion pipe 2, form space, with accommodating tensioning spring 3.
The thickness of described filter paper 1 is 0.01mm.
The stacked number being layered in the filter paper 1 on described central tube at least wants thousand layers.
Described upper guard-plate 5 is fixed dam, and described lower end-stopping plate 6 is sideboard.
The embody rule of this filter is as follows:
Comprise the steps:
A. composition graphs 3, filtration step: external pressure forces liquid to enter from the gap between adjacent filter paper 1, by the axial slits 7 of central tube tube wall, flows into central tube inner, flows out from the upper end open of central tube; In this process, the impurity in liquid stays filter paper outside after stacked Filter paper filtering, and the clean liquid after filtration flows out from central tube upper end;
B. composition graphs 4, cleanup step: compressed air is introduced from central tube upper end open, by the axial slits 7 of central tube tube wall, enter the gap in the middle of adjacent filter paper, filtration is blown off at the impurity of filter paper outside, foreign matter reenters filter process next time after cleaning out, and circulates successively.
Filter paper of the present invention fits tightly through spring is precompressed, can ensure long high-precision filtration; And by blowback scale removal process, can automatically the impurity of filter paper outside be cleaned out, without the need to artificial participation; Filter and carry out with cleaning circulation, no material consumption, cost saving.
Above a kind of high accuracy bypass-filtering device that the application provides is described in detail, apply embodiment herein to set forth the principle of the application and embodiment, the explanation of above embodiment is just for helping method and the core concept thereof of understanding the application; Meanwhile, for one of ordinary skill in the art, according to the thought of the application, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction to the application.
