specific Embodiment approach

[0014] Referring to the accompanying drawings, the specific implementation is as follows:

[0015] A filter element with automatic scrubbing function, comprising a filter element body 1 in a cylindrical structure, and a rotating shaft 2 is mounted on the inner side of the filter element body 1 through two bearing seats 3, such as image 3 As shown, the bearing seat 3 is a hollow cross member, and the four ends of the cross are all connected to the filter body 1, so that the bearing seat 3 will not affect the flow of backwash water in the filter body 1. The axis of the rotating shaft 2 coincides with the axis of the filter core body 1. The rotating shaft 2 is fitted with a brush assembly 4 and a driving blade assembly 5. One end of the rotating shaft 2 is screwed with a screw for limiting the axial displacement of the driving blade assembly 5. Lock nut 6.

[0016] Such as figure 1 As shown, the position corresponding to the brush assembly 4 on the filter element body 1 is a f...

Abstract

A filter element with an automatic brushing function comprises a filter element body of a cylindrical structure, a rotating shaft is installed on the inner side of the filter element body, a brush assembly and a driving fan blade assembly are installed on the rotating shaft in a sleeving mode; the position, corresponding to the brush assembly, of the filter element body is of a folded structure, and the folded structure is composed of a plurality of conical barrel sections in the middle of the filter element body; the conical barrel sections are sequentially connected in the axial direction, the outer circumferential face of the brush assembly is attached to the inner surfaces of the conical barrel sections on the filter element body, the driving fan blade assembly is located on the side,close to the coming direction of back washing water flow, of the brush assembly, the driving fan blade assembly is made to rotate through the back washing water flow, and therefore the rotating shaftdrives the brush assembly to rotate in order to brush the inner surface of the filter element body conveniently. According to the invention, the filter element is flushed by water flow and can be directly brushed by the brush assembly in the backwashing process, the decontamination effect of backwashing on the filter element is greatly improved, and the requirement for long-time use of the backwashing filter after automatic backwashing can be satisfied.

Description

technical field [0001] The invention relates to the field of filter elements, in particular to a filter element with automatic scrubbing function. Background technique [0002] my country's water resources are relatively scarce. With the rapid economic development and the improvement of national environmental awareness, efficient water treatment equipment has been widely used in production and life. Automatic backwash filters are widely used in ballast water systems due to their self-cleaning function. , Industrial and domestic wastewater treatment. The filter element plays a key role as the core filter component of the automatic backwash filter. The existing candle plug-in filter element has insufficient backwash decontamination effect, and the filter is not easy to be backwashed simply by relying on filtered water to filter large particles. It will affect the backwashing effect of the automatic backwashing filter. After a long time of use, dirt will accumulate on the filte...
