Description of the drawings:

FIG. 1 is a cross-sectional view of the present invention;

FIG. 2 is a schematic diagram of a frame structure of the filtering unit of the present invention;

fig. 3 is a schematic structural diagram of the diatomite unit of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, the utility model relates to a diatomaceous earth filter equipment, casing 1 has, water inlet 11, delivery port 12 and the filter element who is arranged in casing 1, be equipped with spacing ring 2 on casing 1's the inner wall, the filter element frame is put in spacing ring 2 top, water inlet 11 is connected on casing 1 of spacing ring 2 below, delivery port 12 is connected on casing 1 of filter element top, treat that the filtrate gets into inside casing 1 from water inlet 11, and rise gradually in the casing, treat that the filtrate is at the in-process through filter element that rises, suspended granule and impurity are held back by filter element absorption in the liquid, liquid after the filtration then flows from delivery port 12, accomplish filtering process.

Specifically, the filter element comprises a frame 5, a plurality of layers of horizontally arranged diatomite units 4 are arranged in the filter element, the diatomite units 4 between two adjacent layers are arranged in a staggered mode, namely a plurality of diatomite units 4 are arranged in each layer at intervals horizontally, and a plurality of diatomite units 4 between two adjacent layers are arranged in a staggered mode, so that the liquid level can sequentially flow through paths formed by the diatomite units 4 in the rising process, the speed is high, and the adsorption effect is good.

In order to facilitate the detachment or replacement of each diatomite unit 4, as shown in fig. 2, the frame 5 is hollowed, the frame 5 may be circular or square, the frame 5 is preferably made of stainless steel, and the side edge of the frame is provided with a plurality of insertion vacant positions 51 for inserting and fixing the diatomite units 4, so that when the diatomite units 4 need to be replaced, the frame 5 is only required to be inclined, and the diatomite units 4 can slide out.

Further, as shown in fig. 3, the diatomite unit 4 includes a filter cloth 41, a filter cloth framework 42 for expanding and fixing the filter cloth 41, and diatomite wrapped in the filter cloth 41, the filter cloth framework 42 is preferably made of stainless steel, the filter cloth 41 is made of a pore size larger than the particle size of the diatomite 43, and the filter cloth 41 is preferably 400-mesh and 600-mesh.
