Problems solved by technology

However, this water purifier is not equipped with a cleaning device, and it is very troublesome to clean after the filter element is blocked, and it is impossible to realize the function of cleaning while filtering
In addition, the filter area of ​​the water purifier is small, if one wants to increase the filter area by increasing the diameter of the microporous ceramic tube, the space in the microporous ceramic tube will be wasted, the equipment will become very large, and the equipment cost will also increase accordingly. increased
So this kind of water purifier can only be used as a small water purifier in occasions that only need to deal with a small amount of water

Embodiment 1

[0050] Embodiment 1: As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, the novel microporous ceramic filter of this embodiment includes a filter housing 5 and the combined microporous ceramic filter element in the shell 5. The microporous ceramic filter element is composed of multiple microporous ceramic sheets 12 that are filtered on both sides on the header 2. The outlet of the header 2 is the outlet of the filter. Each microporous ceramic sheet 12 is provided with a cleaning device, which rotates around the collector tube 2 through a transmission device, and cleans the trapped material on the surface of the microporous ceramic sheet 12 during rotation. The filter housing is also provided with an inlet pipe 13 and a sewage outlet pipe 1, the upper part of which is open, and an end cover 18 is provided at the open.

[0051] The collecting pipe 2 is a round pipe, one end of which is closed by a blind plate 16, and a short pipe 53 fixedly conne...

Embodiment 2

[0056] Embodiment 2: As shown in FIG. 10 , the transmission device of this embodiment is a transmission device powered by mechanical force, and its structure is to set an outer fixed shaft 26 and an inner fixed shaft at the inner and outer corresponding parts of the filter end cover 32 respectively. 28, the inner fixed shaft 28 is installed in the short tube 54 on the upper part of the header 2, the short tube 54 is fixedly connected with the header 2, and the outer turntable 23 and the inner turntable 52 are respectively sheathed on the two fixed shafts 26 and 28. Magnets 27 and 30 are mounted on the turntable, respectively. The outer turntable 23 is provided with a handle 29 on which a press cover 24 and a locking nut 25 are mounted, and are tightened and fixed by the locking nut 25 . A connecting rod 31 is also provided inside the filter. One end of the connecting rod 31 is provided with a rod 33 that can drive the cleaning device to rotate, and the other end is provided wi...

Embodiment 3

[0057] Embodiment 3: As shown in FIG. 11 , the transmission device of this embodiment is also a transmission device powered by mechanical force. 37 is provided with an annular groove on which the sealing ring 39 can be assembled at the fitting part with the shaft sleeve 41 , and the rotating shaft 37 and the shaft sleeve 41 are connected dynamically and sealingly through the sealing ring 39 . The rotating shaft 37 is provided with a rotating rod 38 which is fixed by a spring washer 36 and a nut 35 , and a handle 40 is mounted on the rotating rod 38 . There is also a connecting rod 42 inside the filter. One end of the connecting rod 42 is provided with a rod that can drive the cleaning device to rotate, and the other end is fixedly connected with the rotating shaft 37 . The external power is transmitted to the rotating shaft 37 through the handle 40 , and then to the cleaning device through the connecting rod 42 . The handle 40 and the rotating rod 38 can also be replaced by a...

Abstract

A millipore ceramic filter is composed of a casing with inlet and blow-off outlet, and a combined filter core consisting of a fluid collecting pipe, multiple millipore ceramic plates with two filtering surfaces and installed to said fluid collecting pipe, and a washing unit consisting washing devices (one for each ceramic plate). Its advantages are high throughput, large filtering area, long service life and low resistance to fluid.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a novel microporous ceramic filter which can filter, clean and discharge sewage simultaneously. Background technique [0002] Microporous ceramics used as filter materials have many advantages, such as low cost, can be cleaned after clogging, the flow is basically restored after cleaning, the filtration accuracy does not decrease, and the quality of the liquid (or gas) can be maintained throughout the filtration process. stable, etc. Therefore, filters made by using microporous ceramics as filter materials have been widely used. [0003] The shape of microporous ceramics is generally plate, tubular or hemispherical. During filtration, the water flow enters from one side and flows out from the other side, and the contaminants are blocked on one surface of the feed and deposit or accumulate on the surface to form a filter cake. As the filtration process progresses, the thickn...
