A kind of new-type bioreactor
Technical field
This utility model relates to a kind of new-type bioreactor, belongs to sewage treatment area.
Background technology
Biological rotating disk is a kind of common equipment of biomembrance process dirty water living creature processing technique, at present conventional biological rotating disk by many major diameters, the disc of lightweight forms, its center is fixed on the trunnion axis of sewage storage tank, and can rotate slowly with axle, about the 40% of disc area is immersed in the sewage of sewage storage tank, and microorganism is attached to disc surface.When sewage flows through equipment aqua storage tank, bio-disc starts to rotate, and the microorganism being attached on disc is fully contacted with sewage, and microorganism carries out biological metabolism reaction with the pollutant in sewage for nutrition, thus realizes dirty water purification.In existing biological rotating disk, due to existing new-type bioreactor in use for some time, mud can be at cell body bottom deposit, on the one hand aeration is affected, on the other hand TORQ is increased, reactor shell such as fruit structure is firm not, will produce vibration and even rupture, and the equipment that affects runs.
Utility model content
The deficiency existed for prior art, technical problem to be solved in the utility model is to provide a kind of new-type bioreactor, and service life is long.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of new-type bioreactor, including reaction cell body, the described reaction cell body left and right sides is provided with motor mounting rack, is provided with biological rotating disk axle between the motor mounting rack of the left and right sides, and described biological rotating disk axle is provided with multiple biological rotating disk being arranged in parallel, described biological rotating disk axle one end connects electric rotating machine, and electric rotating machine is connected with reaction cell body by motor mounting rack;The middle part of described biological rotating disk axle is provided with a central plate, and the end of outermost two biological rotating disks is respectively arranged with an end plate, and end plate is socketed on biological rotating disk axle;Be respectively provided with on described central plate and end plate porose group I, hole group II, hole group III;Described hole group I, hole group II, hole group III are ring-type equally distributed some through holes, hole group I, hole group II, hole group III and central plate and the homocentric setting in the center of circle of end plate, and the center of circle distance of hole group I, hole group II, hole group III to central plate and end plate once reduces;Described hole group I includes 18 through holes, and hole group II includes that 12 through holes, hole group III include 6 through holes.
Optimize, above-mentioned new-type bioreactor, between described central plate and biological rotating disk axle, be provided with reinforced support.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Cell body can be carried out backwash, thus discharge being deposited on the mud bottom cell body, it is ensured that normal aeration and the operating of rotating disk, reduce the risk of rotary shaft fracture, improve the service life of equipment.Add central plate and end plate, and central plate connects biological rotating disk axle by reinforced support, improves using effect and service life further.

Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of new-type bioreactor, including reaction cell body, the described reaction cell body left and right sides is provided with motor mounting rack, biological rotating disk axle it is provided with between the motor mounting rack of the left and right sides, multiple biological rotating disk being arranged in parallel it is provided with on described biological rotating disk axle, described biological rotating disk axle one end connects electric rotating machine, and electric rotating machine is connected with reaction cell body by motor mounting rack;The middle part of described biological rotating disk axle is provided with a central plate, and the end of outermost two biological rotating disks is respectively arranged with an end plate, and end plate is socketed on biological rotating disk axle;Be respectively provided with on described central plate and end plate porose group I, hole group II, hole group III;Described hole group I, hole group II, hole group III are ring-type equally distributed some through holes, hole group I, hole group II, hole group III and central plate and the homocentric setting in the center of circle of end plate, and the center of circle distance of hole group I, hole group II, hole group III to central plate and end plate once reduces;Described hole group I includes 18 through holes, and hole group II includes that 12 through holes, hole group III include 6 through holes.It is provided with reinforced support between described central plate and biological rotating disk axle.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Cell body can be carried out backwash, thus discharge being deposited on the mud bottom cell body, it is ensured that normal aeration and the operating of rotating disk, reduce the risk of rotary shaft fracture, improve the service life of equipment.Add central plate and end plate, and central plate connects biological rotating disk axle by reinforced support, improves using effect and service life further.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above; those skilled in the art; in essential scope of the present utility model, the change made, retrofit, add or replace, all should belong to protection domain of the present utility model.
