The filter element of the filter plays a key role as a core filter part of the automatic backwashing filter, the existing candle-type filter element has insufficient backwashing decontamination effect, the filter screen is backwashed by only depending on filtered water, large-particle substances are not easy to be backwashed, the backwashing effect of the automatic backwashing filter is influenced, dirt is gathered on the filter element of the backwashing filter after long-time use, the backwashing filter needs to be detached and cleaned frequently, and the requirement of long-time use of the backwashing filter after automatic backwashing can not be met.
Disclosure of Invention
In order to solve the problem that the existing filter element has insufficient backwashing effect, the invention provides a filter element with an automatic scrubbing function.
The technical scheme adopted by the invention for solving the technical problems is as follows: a filter element with an automatic scrubbing function comprises a filter element body which is of a cylindrical structure, a rotating shaft is installed on the inner side of the filter element body through two bearing seats in a matched mode, the axis of the rotating shaft is overlapped with the axis of the filter element body, a brush component and a driving fan blade component are sleeved on the rotating shaft, the position, corresponding to the brush component, on the filter element body is of a folded structure, the folded structure is composed of a plurality of conical cylinder sections in the middle of the filter element body, the plurality of conical cylinder sections are sequentially connected in the axial direction, the directions from the large end opening to the small end opening of two adjacent conical cylinder sections are opposite, the sections of the plurality of conical cylinder sections in the radial direction of the filter element body are in a sawtooth shape, the outer peripheral surface of the brush component is attached to the inner surfaces of the plurality of conical cylinder sections on the filter element body, the driving fan blade component is located on one side, close to, thereby make the rotation axis drive the brush subassembly and rotate to the brush subassembly is scrubbed the filter core body.
Preferably, the bearing block is a hollow cross-shaped component, and four ends of the cross shape are connected with the filter element body.
Preferably, one end of the rotating shaft is screwed with a locking nut for limiting the axial displacement of the driving fan blade assembly.
Preferably, all the conical shell sections are equal in size, and two adjacent conical shell sections are symmetrically arranged.
According to the technical scheme, the invention has the beneficial effects that:
according to the filter element with the automatic scrubbing function, the brush component and the driving fan blade component are additionally arranged in the filter element, so that the brush component can be driven to rotate by the driving fan blade component when the filter element is subjected to back washing, the inner surface of the filter element body can be scrubbed by the brush component, the filter element is not only subjected to the washing effect of water flow in the back washing process, but also can be directly scrubbed by the brush component, the decontamination effect of the back washing on the filter element is greatly improved, and the requirement of the back washing filter for long-time use after automatic back washing can be met. The position that corresponds with the brush subassembly on the filter core body is the rugate structure, is convenient for adjust the area of overflowing of filter core body, when the flow of needs increase or reduction filter core, only needs to change the angle between the conical surface of conical shell ring section and the filter core axis in the rugate structure, thereby the area of overflowing that just can change the filter core body adapts to different flow demands. The brush component can be made of different materials according to different materials of the filter element, so that the purpose of adapting to corresponding working conditions is achieved. The fan blades at different angles can be adopted by the driving fan blade assembly, namely the fan blades at different angles are adopted according to different models of filter elements, so that the backwashing effect is improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view of a drive blade assembly;
fig. 3 is a cross-sectional view of the bearing housing.
The labels in the figure are: 1. the filter element body comprises a filter element body 101, a conical cylinder section 2, a rotating shaft 3, a bearing seat 4, a brush assembly 5, a driving fan blade assembly 6 and a locking nut.
Detailed Description
Referring to the drawings, the specific embodiments are as follows:
the utility model provides a filter core with automatic scrubbing function, is including the filter core body 1 that is the tubular structure, and filter core body 1 inboard is installed a rotation axis 2 through two bearing frame 3 cooperations, and as shown in figure 3, bearing frame 3 is the fretwork cross component, and four ends of cross all are connected with filter core body 1 to make bearing frame 3 can not influence the flow of back flush rivers in filter core body 1 inside. The axis of rotation axis 2 and the axis coincidence setting of filter element body 1, the cover is equipped with brush subassembly 4 and driving fan blade subassembly 5 on the rotation axis 2, and the one end of rotation axis 2 is twisted and is equipped with lock nut 6 that is used for restricting 5 axial displacement of driving fan blade subassemblies.
As shown in fig. 1, a position on the filter element body 1 corresponding to the brush assembly 4 is a folded structure, the folded structure is composed of a plurality of conical cylinder sections 101 at the middle part of the filter element body 1, the plurality of conical cylinder sections 101 are sequentially connected along the axial direction, the directions of the large end opening to the small end opening of two adjacent conical cylinder sections 101 are opposite, so that the plurality of conical cylinder sections 101 are zigzag along the radial cross section of the filter element body 1, the outer peripheral surface of the brush assembly 4 is attached to the inner surface of the plurality of conical cylinder sections 101 on the filter element body 1, the driving fan blade assembly 5 is located at one side of the brush assembly 4 close to the direction of the back washing water flow, the driving fan blade assembly 5 is rotated by the back washing water flow, and thus the rotating shaft 2 drives the brush assembly 4 to rotate, so that the brush assembly 4 can brush the inner surface of.
In the embodiment, when the filter element body 1 is subjected to the flushing action of water flow during backwashing, the filter element body is directly scrubbed by the brush component 4, the decontamination effect of the backwashing on the filter element is greatly improved, and the requirement of the backwashing filter for long-time use after automatic backwashing can be met.
