Abstract
The utility model relates to a filter element of a high pressure backwash filter, belonging to the technical field of filtering equipment. The filter element of the high pressure backwash filter comprises a filter element body, wherein the filter element body comprises an inner supporting skeleton and an outer supporting skeleton, which are cylindrical and are concentrically sleeved, a filtering layer is arranged between the inner supporting skeleton and the outer supporting skeleton, and is a corrugated cylinder body formed by folding three layers of overlapped filter screens. According to the filter element provided by the utility model, the filtering layer is a corrugated cylinder body, so that the filtering area of the filter element is increased on the condition of not changing the size of the filter element, so that the flow rate of the filter element is increased, the resistance is reduced and the number of the used filter elements is decreased on the condition of constant flow rate of the filtering equipment; meanwhile, the filtering layer is composed of three layers of filter screens, so that the strength of the filtering layer is enhanced and high pressure liquid is prevented from puncturing the filtering layer when the filter element is used. The filter element provided by the utility model is simple in structure, and the flow resistance of the filter element is reduced and the service life of the filter element is prolonged.
Description
Technical field
The utility model relates to a kind of filter core, relates in particular to the filter core of the high pressure backwash filter of the impurity in a kind of filtered water and the emulsion, belongs to the filter plant technical field.
Background technology
The high pressure backwash filter station is for the filter plant between emulsion power pack and the hydraulic support, the core component of filter station is filter core, the performance quality of filter core directly determines flow resistance and the service life of filter station, under the certain prerequisite of filter plant flow, the size of filter core metered flow has determined that filter core uses number in the filter plant.And the core component of filter core is filter course, and under the certain prerequisite of filtering accuracy, the filter area of filter core has determined parameters such as the flow resistance of filter core and service life.The filter core of prior art is the interior support frame outer surface that directly filter screen is enclosed in tubular, support frame outside the outer surface of filter screen arranges then.The filter core of this purse seine formula structure is only played a role in filtering by periphery, and filter area is less, causes the metered flow of filter core less, need increase the quantity of filter core during the operation of high pressure backwash filter station, thereby the production cost of high pressure backwash filter station is increased.
Summary of the invention
It is a kind of under the prerequisite that does not change the filter core size that the purpose of this utility model is to provide, can increase the filter core of the high pressure backwash filter of filter area, with the technical problem that the filter core usage quantity is many, production cost is high in the high pressure backwash filter station that solves prior art.
For achieving the above object, the utility model adopts following technical scheme: the filter core of high pressure backwash filter, comprise filter body, filter body comprises the concentric sheathed inside and outside support frame that is tubular, be provided with filter course between the inside and outside support frame, described filter course is the corrugated cylindrical shell that is folded into by the three stacked screen packs of putting together.
The ripple of described corrugated cylindrical shell extends along the circumferencial direction of cylindrical shell.
Crest height on the described corrugated cylindrical shell is less than or equal to 7mm.
The three layer filtration net of described filter course is followed successively by stainless steel wire mesh grid, braid fabric and stainless steel wire mesh grid.
Filter course of the present utility model is the corrugated cylindrical shell, and this just under the prerequisite that does not change the filter core size, increases the filter area of filter core, thereby increase the filter core flow, reduces resistance, under the certain prerequisite of filter plant flow, has reduced the use number of filter core.Therefore, when the utility model is used for the high pressure backwash filter station, do not need to increase the quantity of filter core, thereby production cost is reduced; Simultaneously, filter course of the present utility model is to be made of the three layer filtration net, and the intensity that this has just increased filter course prevents filter core highly pressurised liquid puncture filter course in use.The utility model is simple in structure, the flow resistance of filter core is reduced, prolong service life.
Further, the height of crest is less than or equal to 7mm on the filter course, prevents that filter course from deforming under the operating pressure of 31.5MPa.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the high pressure backwash filter core of present embodiment comprises filter body, should the end cap (not shown) be set respectively at the filter body two ends during use, filter body comprises concentric sheathed interior, the support frame 3,1 that is tubular, be provided with filter course 2 between the inside and outside support frame 3,1, filter course 2 is the corrugated cylindrical shells that are folded into by the three stacked screen packs of putting together, and the ripple of this corrugated cylindrical shell extends along the circumferencial direction of cylindrical shell, and the crest height on the corrugated cylindrical shell equals 7mm.The three layer filtration net of filter course is followed successively by stainless steel wire mesh grid, braid fabric and stainless steel wire mesh grid.
The filter course of present embodiment is the corrugated cylindrical shell, and this just under the prerequisite that does not change the filter core size, increases the filter area of filter core, thereby increase the filter core flow, reduces resistance, under the certain prerequisite of filter plant flow, has reduced the use number of filter core.Therefore, when present embodiment is used for the high pressure backwash filter station, do not need to increase the quantity of filter core, thereby production cost is reduced; Crest height equals the design of 7mm, prevents that filter course from deforming under the operating pressure of 31.5MPa; Simultaneously, the filter course of present embodiment is to be made of the three layer filtration net, and the intensity that this has just increased filter course prevents filter core highly pressurised liquid puncture filter course in use.The utility model is simple in structure, the flow resistance of filter core is reduced, prolong service life.
In other embodiment of the present utility model, the ripple of corrugated cylindrical shell also can extend along the axis direction of cylindrical shell.
In other embodiment of the present utility model, the crest height of corrugated filter course also can be less than 7mm; Filter course also can be made of the three-layer metal wire gauze filter, can also and be folded in the middle stainless steel wire mesh grid of double layer of metal silk screen by the double layer of metal wire gauze filter and constitute.
