A kind of bioreactor
Technical field
This utility model relates to a kind of 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 bioreactor in use for some time, mud can be at cell body bottom deposit, on the one hand affecting aeration, on the other hand TORQ is increased, reactor shell such as fruit structure is the most firm, will produce vibration even to rupture, 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 bioreactor, and service life is long.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of 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, electric rotating machine is connected with reaction cell body by motor mounting rack, described reaction cell body bottom side is provided with backwash mouth, bottom described reaction cell body, opposite side is provided with sewage draining exit;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;Described central plate and end plate are discoid, and its diameter is identical and less than the diameter of biological rotating disk;The straight line at the diameter place of described biological rotating disk axle is higher than reaction place, cell body upper surface plane in vertical dimension, and its distance is 50MM.
Optimize, above-mentioned bioreactor, between described central plate and biological rotating disk axle, be provided with reinforced support.
Optimizing, above-mentioned bioreactor, described reaction cell body side is provided with air supply pipe, is provided with aeration tube bottom described reaction cell body, and described air supply pipe is connected with aeration tube.
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.

In figure: 1 be reaction cell body, 2 be motor mounting rack, 3 be biological turntable shaft, 4 be biological rotating disk, 5 be electric rotating machine, plate centered by 6,7 be end plate, 8 be reinforced support.
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 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, electric rotating machine is connected with reaction cell body by motor mounting rack, described reaction cell body bottom side is provided with backwash mouth, and bottom described reaction cell body, opposite side is provided with sewage draining exit;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;Described central plate and end plate are discoid, and its diameter is identical and less than the diameter of biological rotating disk;The straight line at the diameter place of described biological rotating disk axle is higher than reaction place, cell body upper surface plane in vertical dimension, and its distance is 50MM.It is provided with reinforced support between described central plate and biological rotating disk axle.Described reaction cell body side is provided with air supply pipe, is provided with aeration tube bottom described reaction cell body, and described air supply pipe is connected with aeration tube.
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.
