Abstract

The present invention is installed in the aeration tank of the sewage and wastewater treatment plant, and the air supplied from the blower is micro-bubbled and sprayed to efficiently dissolve the oxygen in the air in the sewage and wastewater. Disc type membrane diffuser device to achieve proper mixing to biologically decompose and remove material (SUSPENDED SOLIDS: SS) and to prevent precipitation in the aeration tank.

Description

Saddle prefabricated airflex disc membrane diffuser

The purpose of the present invention is to supply air from the blower during the process of purifying wastewater by supplying oxygen to the microorganisms of AERATION TANK in the process of biologically treating sewage and wastewater. As a device for finely spraying air, the diffuser with this purpose is PE type and ceramic (CERAMIC).

The present invention facilitates the assembly and disassembly of the base (BASE.1) and retaining nut (RETAINING NUT.2) for fixing the membrane (MEMBRANE.3), making it convenient for maintenance. After assembling SADDLE.11-1), assembling the diffuser (DIFFUSER.3), the airtightness and disassembly and assembly are easy.

The present invention is made of a membrane (MEMBRANE.3) made of natural rubber (EPDM) or urethane (URETANE RUBBER), silicone (SILICON RUBBER), and the like will be described in detail with reference to the drawings, the configuration of the present invention is the first and second As shown in Figs. 3 and 4, the main part has a main body base (BASE.1), a retaining nut (RETAINING NUT. 2), a membrane (MEMBREN. 3), a saddle (SADDLE. 11-1), and a clamp. (CLAMP.11-2), ROCKING HANDLE.11-3, SEALING RUBBER.11-4, etc .. Its function and shape is through the air supply pipe (9). When the supplied air is introduced into the diffuser through the orifice hole (ORIFICE HOLE.4) of the base (BASE.1), the membrane fixed by the base (BASE.1) and the retaining nut (RETAINING NUT.2) (MEMBRANE.3) expands and at this time, a large number of micropores opened through the entire effective area of the membrane are opened and Thereby ejecting microbubbles worked. When the air supplied to the air supply pipe (9) is stopped, the pores of the membrane immediately return to the original state, which prevents the inflow of wastewater back and the check valve function to prevent the double inflow of wastewater. The non-return valve 6 has a function of a check valve by water pressure at the center of the upper surface of the base.

The base has six radial reinforcement blades 7 on the base surface to prevent distortion and disassembly of the base, and twelve concave disassembly grooves 5 on the retaining nut. The assembly surface between the base (BASE.1) and the retaining nut (RETAINING NUT.2) is a square screw (four screws SCREW.8) to prevent loosening and release due to vibration and pressure changes.

Also, in order to facilitate the pipe work, disassembly and installation, place a saddle (SADDLE.11-1) on the top of the pipe and seal rubber (SEALING RUBBER.11-4), clamp (CLAMP.11-2) and locking handle (ROCKING HADLE). .11-3) and then fitted with a saddle arrangement to allow the saddle and diffuser to be assembled with a nipple (NIPPLE.10) with a tapered threaded pipe under the base (BASE.1).

The effect of the present invention configured as described above is to prevent the backflow in the first place, so that foreign matter does not accumulate inside the diffuser, so that it can be used for a long time. Second, because the air bubbles ejected from the membrane are fine, the oxygen transfer efficiency can be improved in the wastewater. The assembly and disassembly of the furnace base and retaining nut are easy, and the unity is strong. It is strong against vibration. Fourth, the work process is achieved by fastening the pipe assembly saddle to the pipe and assembling the diffuser to the saddle. simple.
