Description

Technical Field

[0001] The invention relates to the technical field of ceramic membranes, in particular to a flat plate rotating ceramic membrane configuration with a waterwheel structure. Background Art

[0002] Forcing air into sewage and stirring the liquid can increase the dissolved oxygen content in the sewage and enhance the decomposition of organic matter by microorganisms in the sewage. At the same time, highly dispersed tiny bubbles can act as carriers to adhere to the surface of solid pollutants in the sewage, causing the pollutants to float to the water surface to form foam, thereby achieving solid-liquid separation. These two effects significantly improve the sewage quality, achieving the economy and environmental protection of sewage treatment.

[0003] Ceramic membrane is a porous physical screening material, and its structure mainly includes flat ceramic membrane, tubular ceramic membrane, butterfly ceramic membrane, etc. Through technological innovation and process improvement, the pore size of ceramic membrane can be adjusted to 0.05~5μm, and it has been widely used in solid-liquid separation, gas-solid separation, liquid-liquid separation and other fields. Using the micro-pores of ceramic membrane to ventilate sewage and achieve flotation purification of sewage has been a hot topic in research and application in recent years, especially the industrialization of rotating butterfly ceramic membrane, which has promoted the relevant research of ceramic membrane in the field of flotation purification.

[0004] However, there are still some technical problems that are difficult to solve in the flotation purification process of the existing rotating butterfly ceramic membrane. The membrane assembly of the existing rotating ceramic membrane is troublesome to replace. If one of the 20 to 30 ceramic membranes in a group fails, all the membrane assemblies must be dismantled, replaced, and assembled for maintenance, which greatly reduces work efficiency. The existing rotating ceramic membrane has a small action surface when rotating in sewage and cannot form a large turbulence phenomenon. The dispersion and distribution of micro-nano bubbles in sewage are weak. The existing rotating ceramic membrane needs to remove surface pollutants through high-speed rotation, which leads to high operating energy consumption and easy damage to the membrane and equipment. Therefore, it is of great significance to improve the shortcomings of the existing rotating ceramic membrane in configuration and its application in the field of flotation purification of sewage.

[0025] The ceramic membrane unit 3 includes a flat ceramic membrane 3-1 and a ventilation component 3-2; the ventilation component 3-2 is arranged at both ends of the flat ceramic membrane 3-1, and the flat ceramic membrane 3-1 is provided with 6-12 pieces, with a length of 50-80cm and a width of 10-20cm; the flat ceramic membrane 3-1 is made of inorganic ceramic powder material, including a combination of one or more of aluminum oxide, zirconium oxide, titanium oxide, and silicon carbide; the average pore size of the flat ceramic membrane 3-1 is 0.05~1μm, the porosity of the flat ceramic membrane 3-1 is greater than 35%, and the flexural strength is greater than 80MPa.

[0026] The flange pipe body 1-1 is arranged on the side of the connecting chassis base 2-1 away from the connecting chassis groove 2-2, and the connecting chassis groove 2-2 is the same as the number of the flange pipe openings 1-2. The flat ceramic membrane 3-1 is embedded in the connecting chassis groove 2-2 through the ventilation component 3-2. Therefore, the number of the flange pipe openings 1-2 is the same as the number of the flat ceramic membrane 3-1. The connecting chassis grooves 2-2 on the connecting chassis at both ends of the flat ceramic membrane 3-1 correspond to each other. The flange pipe openings 1-2 and the ventilation component 3-2 on the same side of the flat ceramic membrane 3-1 are connected by a ventilation pipe, and the flange pipe openings 1-2 correspond to the ventilation component 3-2 one by one. After assembly, a flat rotating ceramic membrane configuration with a waterwheel structure is formed.

[0027] The flange pipe body 1 - 1 is connected with a ventilation rotating shaft, and the rotation speed of the ventilation rotating shaft is 20-60r / min, driving the flange pipe 1, the connecting chassis 2 and the ceramic membrane unit 3 to rotate at the same speed.

[0028] The ventilation rotating axis transports compressed air into the flange pipe 1, and the compressed air passes through the flange pipe opening 1-2, the ventilation pipe and the ventilation component 3-2 in sequence, and is finally transmitted to the surface of the flat ceramic membrane 3-1 and discharged to form micro-nano bubbles.

[0029] Example like Figure 1-6 As shown, the present invention provides a flat-plate rotating ceramic membrane configuration of a waterwheel structure, which is composed of 2 flange pipes 1, 2 connecting chassis 2, and 12 ceramic membrane units 3.

[0030] The opening of the flange pipe body 1-1 is used to connect the rotating shaft for ventilation, and the flange pipe connecting base 1-3 is fixed on the plane of the connecting chassis base 2-1; the 12 flat ceramic membranes 3-1 and the ventilation components 3-2 are sealed and connected by epoxy resin glue, and the ventilation components 3-2 of the ceramic membrane unit 3 are sequentially embedded in the connecting chassis groove 2-2; the flange pipe openings 1-2 and the ventilation components 3-2 are connected one by one by air pipes, and after assembly, a flat rotating ceramic membrane configuration with a waterwheel structure is formed.
