Description
The utility model relates to a kind of biochemical processing device.
In same pond, realize that aerobic aeration and anaerobism stir two kinds of biochemical treatment operating modes, current adopt is provided with the way that air diffuser and two kinds of equipment of stirrer are worked respectively more, and it exists, and equipment is many, cost is high, manage shortcoming such as inconvenience.
Existing air diffuser (being commonly called as aeration head) generally is fixed at the bottom of the pond on the air line, and bubble is escaped outside the pond vertically upward, and air water is short duration of contact, the transfer of unfavorable oxygen.The rubber diaphragm of aeration head is limited by processing conditions, can only form the small bubbles of 2-5 mm dia, and is still big inadequately with water engaging surface.Therefore, total transfer efficiency of oxygen is not high.Simultaneously, the pressure-losses is big, is not suitable for dark pond and uses, and the working life phase is short, upgrades the maintenance trouble.
Existing stirrer could guarantee that sewage mixes with the effective of active sludge because the sphere of action restriction often needs many to use simultaneously, and equipment is many, and complex management is its shortcoming.
The utility model provides a kind of cost low at the weak point that above-mentioned prior art exists, and the pressure-losses is little, can not stop up, and two-purpose machine is stirred in installation, maintenance underwater jet aeration easily.
Technical solution of the present utility model:
A kind of underwater jet aeration stirs two-purpose machine, it is characterized in that it is by motor, retarding mechanism, casing, gas inlet chamber, bearing and impeller are formed, the top of bearing links to each other with casing, casing is a circular cavity body, its perisporium is provided with a plurality of runner holes of tangentially stretching out, be provided with disk of conical profile in the casing, this impeller is made of the blade of one on conical cavity body and its outer wall, conical cavity body end face has a plurality of air inlet ports, its corresponding each blade one side position is provided with a plurality of production wells, the wheel shaft of impeller links to each other with the output shaft of retarding mechanism, retarding mechanism is packed on the casing, and retarding mechanism links to each other with the motor seal waterproof, is connected with gas inlet chamber on casing, gas inlet chamber is communicated with the chassis cavity body, and the gas inlet chamber surface is provided with air inlet port.
The utlity model has following advantage:
1, a machine dual-purpose has replaced huge air diffuser of quantity and special-purpose stirring machine.Equipment is few, and favourable reduction cost reduces construction investment.
2, owing to the special tectonic and the streamflow regime of Aeration stirrer, air is sheared into micro-bubble, and has prolonged duration of contact.Thereby improved actual oxygen transfer efficiency (improving about 0.3-1.0 doubly) greatly than existing micro-hole aerator.
3, water and air mixed are soft, and biological cenobium is not produced shearing action, favourable biological treatment adsorption process.
4, the pressure-losses is little.
5, can never stop up.
6, being particularly suitable for dark pond (10-15m) uses.
7, directly place at the bottom of the pond, need not fixation, installation, maintenance is convenient.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
As Fig. 1,2, the utility model is by motor 1, retarding mechanism 2, casing 3, gas inlet chamber 4, bearing 5 and impeller 6 are formed, the top of bearing 5 links to each other with casing 3, casing 3 is a circular cavity body, its perisporium is provided with a plurality of runner holes 7 of tangentially stretching out, be provided with disk of conical profile 6 in the casing 3, this impeller 6 is made of the blade 9 of one on conical cavity body 8 and its outer wall, conical cavity body 8 end faces have a plurality of air inlet ports, its corresponding each blade 9 one side positions are provided with a plurality of production wells 10, the wheel shaft of impeller 6 links to each other with the output shaft of retarding mechanism 2, retarding mechanism 2 is packed on the casing 3, and retarding mechanism 2 links to each other with motor 1 water-tight, is connected with gas inlet chamber 4 on casing 3, gas inlet chamber 4 is communicated with casing 3 cavity body, and gas inlet chamber 4 surfaces are provided with air inlet port 11.
The utility model places under the sewage biochemistry pool when using, the sewage biochemical treatment, not only requiring provides enough oxygen amounts to active sludge, and forbid that sludge settling, this underwater jet aeration stir two-purpose machine and adopt two rotating speed designs, high-speed and continuous operation, elder generation is from air inlet port 11 bubbling airs of gas inlet chamber 4, then air enters casing 3 cavity body naturally, and the air inlet port from disk of conical profile 6 end faces enters again in the conical cavity 8 of impeller 6 simultaneously, and circulates with its each production well 10.Starter motor 1 drives disk of conical profile 6 rotations by retarding mechanism 2 (as adopting the retarding mechanism of gear structure) then, under impeller 6 effects, form eddy current, air is cut into the runner hole 7 of micro-bubble by each tangential direction of casing 3 evenly to charge in the water, and, realize the oxygenation function to diffusion all around.Within the specific limits, regulate air input, the depth of water can satisfy the aeration requirement of various special process in the 5-12m scope.The utility model is when stirring work, by valve 12 air induction hose 13 at air inlet port 11 places of gas inlet chamber 4 is closed earlier, cut off air, then motor 1 changes low cruise automatically over to, realize not aeration agitation work of low speed, rely on the open design of this machine, suck sewage to around eject, the realization solids does not precipitate, have efficient, energy-conservation, handiness is strong, simple operation and other advantages.
