Abstract
The utility model relates to a submersible aerator for sewage treatment, which comprises a submersible motor, an impeller driven by the submersible motor, and an air inlet pipe, wherein the air inlet pipe is a rigid pipe and is vertically arranged, the lower end is fixedly connected with the submersible motor by an air inlet connecting pipe and the upper end is fixedly connected with a floating body. Accordingly, an original side air inlet mode is changed into a center air inlet mode and smooth air inlet is still maintained. As the upper part of the air inlet pipe is additionally provided with the floating body, the floating body, the air inlet pipe and the aerator are integrally connected; the aerator is suspended in water depending on water buoyancy, and accordingly, the utility model can not be limited by conditions under water. When the utility model is positioned, the floating body can be dragged by thee wire cables, and the other ends of the wire cables are fixed on the pond bank, or are provided with three anchor points in a pond to fix; when the utility model is repaired, just the wire cables fixed on the pond bank need loosening, a device is pulled back to the pond bank and is hung out of the water surface and the operation is convenient.
Description
Technical field
The utility model relates to a kind of underwater jet aeration machine that is used for sewage disposal, especially a kind of improvement of underwater jet aeration machine installing structure.
Background technology
Aeration is one of most important technical process of sewage biochemical treatment activated sludge process.The impeller that aerator is driven by submersible machine, the inlet pipe that is placed in submersible machine one side are formed.During use, by location at the bottom of focusing on the pond.During maintenance, if in the sewage lagoon water is arranged, personnel can't operate by lower storage reservoir, need stretch into crane to lift in the pond or arranged in the pond and carried behind the water, and are very inconvenient.And this installation form must have hard ground under water or platform to support, and can't install there not being the occasion (as oxidation pond, fishpond, landscape lake, sewer, river course etc.) that supports the bottom surface, thereby use range is very limited.
The utility model content
The utility model wants the technical solution problem to be: at the shortcoming that above prior art exists, propose a kind of installation and be not subjected under water that surface condition limits, can arbitrarily move, maintenance operation is dived under water floating type aerator easily.
In order to solve above technical problem, impeller and inlet pipe that the floating type aerator of diving of the present utility model comprises submersible machine, driven by submersible machine, described inlet pipe is a rigid pipe, positioned vertical, fixedlying connected with the underwater jet aeration body by air inlet tube in the lower end, fixedlys connected with buoyancy aid in the upper end.
Like this, change the air inlet of former next door into center air inlet or the air inlet of bilateral symmetry, still keep air inlet smooth and easy.Because inlet pipe top adds buoyancy aid, buoyancy aid, inlet pipe, underwater jet aeration body connect into an integral body, rely on buoyancy of water that aerator is suspended in the water, therefore are not subjected to the restriction of water-bed condition.During the location, buoyancy aid can be with three wireline tractives, and the other end of wireline is fixed at pool side, or establishes three anchor points and fix in the pond.During maintenance, a wireline that only needs to be fixed on pool side is untied, and equipment is retracted pool side hang out the water surface and get final product, and is very convenient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Embodiment one
The floating type aerator of the diving of present embodiment as shown in Figure 1, underwater jet aeration body and submersible machine 1 are just being put, blade 6 is positioned at the lower end of submersible machine main shaft.Submersible machine is equipped with air inlet tube 21 time, forms the air chamber that is communicated with air outlet bottom through blade 6 between electric machine casing and the air inlet tube 2.Upper end, air inlet tube 2 both sides is connected with the inlet pipe 3 that stainless steel or carbon steel are made respectively, fixedlys connected with water wing 4 in the upper end of inlet pipe 3, and sound damper 7 is equipped with at the top.
Present embodiment changes the next door air inlet into the center air inlet on former aerator basis, water wing, inlet pipe, underwater jet aeration body connect into integral body.During use, water wing relies on buoyancy of water that aerator is suspended in the water, on the water wing with three wireline 5 tractives fixing (or in the pond, establish three anchor points and fix) on the pool side, settle very convenient.During maintenance, a wireline that only needs to be fixed on pool side is untied, and equipment is retracted pool side hang out the water surface and get final product.
Facts have proved, present embodiment make installation more convenient, save time, the saving of labor, expanded the use range of underwater jet aeration simultaneously.
Embodiment two
The floating type aerator basic condition of the diving of present embodiment is identical with embodiment one, and difference is that submersible machine 1 is inverted, and blade 6 is positioned at submersible machine main shaft upper end.The inlet pipe 3 that air inlet tube 2 connects on the submersible machine 1 is communicated with blade 6 radial air outlets.
Its principle of work is not given unnecessary details in addition referring to embodiment one.
In addition to the implementation, the utility model can also have other embodiments.All underwater jet aeration machines adopt the unsteady installation form of similar structures, no matter adopt which kind of buoyancy aid: as keg float, buoyancy tank, pontoon etc.; No matter adopt which kind of floating body material: as glass reinforced plastic, carbon steel, stainless steel, gas crusty pancake, plastics, timber etc.; No matter which kind of mode of connection buoyancy aid adopts with the underwater jet aeration machine: as flange be connected, shaped steel connection etc.; All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
- One kind diving floating type aerator, comprise submersible machine, by impeller and inlet pipe that submersible machine drives, it is characterized in that: described inlet pipe is a rigid pipe, positioned vertical, fixedlying connected with the underwater jet aeration body by air inlet tube in the lower end, fixedlys connected with buoyancy aid in the upper end.
- 2. according to the floating type aerator of the described diving of claim 1, it is characterized in that: described underwater jet aeration body is just put, blade is positioned at the lower end of submersible machine main shaft, under described submersible machine, air inlet tube is housed, form the air chamber that is communicated with air outlet bottom through blade between electric machine casing and the air inlet tube, be connected with inlet pipe respectively on the described air inlet tube both sides.
