Description

Technical Field

[0001] The utility model relates to a rotating ceramic diaphragm. Background Art

[0002] Compared with the traditional ceramic membrane filtration system, the dynamic ceramic membrane filtration system has a filter element (ceramic membrane) that rotates dynamically during use. For the dynamic filtration separation system, the ceramic membrane is one of the key components. The traditional ceramic membrane usually has a uniform pore distribution and a small filtration area. When the stock solution concentration is high, the filter cake is easy to accumulate on the ceramic membrane, causing blockage and affecting the filtration efficiency. Utility Model Content

[0003] The utility model aims to disclose a rotating ceramic diaphragm, wherein the upper and lower surfaces of the ceramic diaphragm are both honeycomb-shaped protrusions, which increase the number of filter holes, increase the contact area with the liquid, increase the filtration area, and the honeycomb-shaped protrusions have a stirring and disturbing effect, which accelerates the flow between the liquid and the ceramic diaphragm. The filter cake is not easy to deposit on the ceramic diaphragm, and it is not easy to cause blockage, thereby improving the filtration efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides a rotating ceramic diaphragm, including a hollow rotating shaft, spacers and ceramic diaphragms alternately sleeved on the hollow rotating shaft; the side wall of the ceramic diaphragm mounting hole is provided with a plurality of liquid outlets, the hollow rotating shaft is provided with a plurality of liquid inlets, the liquid outlets and the liquid inlets are opposite to each other, a flow channel connected to the liquid outlet is provided inside the ceramic diaphragm, and the upper and lower surfaces of the ceramic diaphragm are both honeycomb-shaped protrusions.

[0005] In some embodiments, two pressure plates are further included which are screwed to the upper and lower ends of the hollow shaft, and the upper and lower pressure plates squeeze and fix the spacer ring and the ceramic diaphragm.

[0006] In some embodiments, a motor for driving the hollow rotating shaft is further included.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: the rotating ceramic diaphragm provided by the utility model has honeycomb-shaped protrusions on the upper and lower surfaces of the ceramic diaphragm, which increases the number of filter holes, increases the contact area with the liquid, increases the filtration area, and the honeycomb-shaped protrusions have a stirring and disturbing effect, which accelerates the flow between the liquid and the ceramic diaphragm. The filter cake is not easy to deposit on the ceramic diaphragm, and it is not easy to cause blockage, thereby improving the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0012] like Figure 1-3 The rotating ceramic diaphragm shown comprises a hollow rotating shaft 1, spacers 3 and ceramic diaphragms 2 which are alternately sleeved on the hollow rotating shaft 1, and a motor (not shown) for driving the hollow rotating shaft 1.

[0013] The side wall of the ceramic diaphragm 2 mounting hole 24 is provided with a plurality of liquid outlets 25, and the hollow shaft 1 is provided with a plurality of liquid inlets 10, the liquid outlets 25 are opposite to the liquid inlet 10, and a flow channel (not shown) connected to the liquid outlet 25 is provided inside the ceramic diaphragm 2. The original liquid enters the ceramic diaphragm 2, and the filtered liquid enters the flow channel, and then flows into the liquid inlet 10 through the liquid outlet 25, and finally enters the hollow shaft 1.

[0014] The upper surface 21 and the lower surface 26 of the ceramic diaphragm 2 are both honeycomb-shaped protrusions 23, which increase the number of filter holes, increase the contact area with the liquid, and increase the filtration area. The honeycomb-shaped protrusions 23 have a stirring and disturbing effect, which accelerates the flow between the liquid and the ceramic diaphragm 2. The filter cake is not easy to deposit on the ceramic diaphragm 2, and it is not easy to cause blockage, thereby improving the filtration efficiency.

[0015] It also includes two pressure plates 4 screwed to the upper and lower ends of the hollow shaft 1. The upper and lower pressure plates 4 squeeze and fix the spacer 3 and the ceramic diaphragm 2, so that the liquid outlet 25 and the liquid inlet 10 remain opposite.

They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.

[0017] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
