Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

The disc filter is formed by combining filter units in parallel, wherein the filter units mainly comprise a group of annular reinforced plastic filter discs with grooves 6 or ribs. When filtering, sewage enters from the outer side, and solid matters in the water are intercepted by a rim formed by the edges of the grooves 6 on the adjacent filter discs; during back flushing, the water flows to the outside from the inside of the annular filter disc, so that the dirt retained on the filter disc is washed and discharged through the sewage outlet. The discs are tightly compacted and overlapped in the unit, and the middle groove 6 between the upper layer and the lower layer of discs plays a role in filtering and intercepting. In the existing disc filter, the gap between adjacent discs is fixed, so that the effect is poor when the disc filter filters solid matters with different sizes in water.

Referring to fig. 1 to 5, in view of this, the present embodiment provides a disc filter for water treatment, which includes a filter cylinder 1, a framework 2 of a filter element 4 is installed in the filter cylinder 1, and the framework 2 of the filter element 4 is sleeved with the filter element 4 formed by stacking a plurality of filter discs 3 in sequence.

The filter discs 3 are all annular, a plurality of grooves 5 are formed in the upper end face and the lower end face of each filter disc 3, and the grooves 5 extend from the outer periphery to the inner periphery of each filter disc 3. Each groove 5 is formed by a plurality of groove bodies which are communicated in sequence, the end surface area of the sewage inlet end of each groove body is larger than that of the sewage outlet end, namely, the end surface area of each groove body facing the outside of the filter disc 3 is larger than that of each groove body facing the inside of the filter disc 3.

It should be noted that, in any two adjacent tank bodies, the area of the end surface of the sewage outlet end of the tank body close to the outside of the filter disc 3 is smaller than the area of the end surface of the sewage inlet end of the tank body close to the inside of the filter disc 3, so that a space for storing solids is formed between the two adjacent tank bodies, and the influence of the solids in the tank body on the sewage filtering efficiency is avoided.

Preferably, the cross section of the groove body is semicircular, after two adjacent filter discs 3 are butted, the corresponding grooves 5 are butted to form a groove 6 with a circular cross section, and the groove 6 is formed by sequentially butting a plurality of round tables. In addition, by rotating the filter discs 3, the grooves 5 can be staggered, so that the size of the grooves 6 achieves the effect of filtering solids with different particle sizes.

In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
