Description

A kind of waste disposal plant with biological drum (drum) of weighting material

The utility model is a kind of waste disposal plant with biological drum (drum) of weighting material, belongs to the biological treatment device of disposing of sewage.

Blodisc is one of existing biological sewage treatment device, and traditional blodisc develops from the biological filter, and it mainly is to be fixed on transverse axis by the less rotary disk of a plurality of mutual spacings to constitute.It is by the continuous rotation of these disks, the microbial film that is grown on the disc is alternately contacted with sewage and atmosphere, organic pollutant in the sewage is attracted on the disc, oxygenolysis under the effect of aerobic microbiological (being microbial film), thus reach the purpose of purifying waste water.But, when the sewage quantity of handling when need is big, must increase the disk disc diameter or increase disc quantity, yet this will causes equipment volume huge, manufacturing expense increases.And, therefore, limited the use range of blodisc waste disposal plant because the increase of disk disc diameter and disk disc quantity all is limited.In addition, this device often has mud to accumulate in oxidation trough, needs regular spoil disposal, and this has just increased the complicacy of operation, and efficient is lower.

The purpose of this utility model be exactly for overcome and solve that prior biological rotating disk waste disposal plant is bulky, manufacturing expense is high, efficient is low, use range is limited, the shortcoming and the problem of complicated operation etc., a kind of volume of research and design is less, expense is low, efficient is high, the waste disposal plant of easy and simple to handle, power and energy saving, the biological drum with weighting material (drum) easy to manufacture, easy to maintenance.

The utility model is realized by following structure technology scheme: a kind of structural representation of biological drum (drum) waste disposal plant with weighting material as shown in Figure 1, the structural representation of biological drum (drum) as shown in Figure 2, its A-A is to sectional view as shown in Figure 3.This device is connected and composed jointly by oxidation trough 1, baffle plate 2, water inlet pipe 3, rotating shaft 4, the nut 5 of belt supporting frame, biological drum (drum) 6, shaft sleeve 7, rising pipe 8 with weighting material, its mutual alignment and annexation are: the oxidation trough 1 of belt supporting frame, its cross section is a semicircular structure, be divided into a plurality of unit with baffle plate 2 in the oxidation trough, the lower left quarter of groove is equipped with water inlet pipe 3, the upper right quarter of groove is equipped with rising pipe 8, one of each cell arrangement has the biological drum (drum) 6 of weighting material, and a plurality of rotating cylinders (drum) can form the reactor of plural serial stage; Connect and compose by cylinder that has many gussets 14 and a plurality of projection 12 and cover plate 9 in the biological drum (drum) 6, cover plate 9 forms detachable being fastenedly connected by projection in screw 13 and the cylinder 12 and cylinder, the whole cylinder of each rotating cylinder (drum) also comprises an inner reinforced plate 14 and the surface of rotating cylinder cover plate 9 offers a plurality of holes of enough areas, in each rotating cylinder inner chamber required weighting material is housed, rotating cylinder (drum) with weighting material passes 7 formation of the interior sleeve of each rotating cylinder (drum) by rotating shaft 4 and is rotatably connected, and by rotating shaft 4, sleeve 7 and nut 5 are cascaded a plurality of biological drums (drum) 6 with weighting material, and the rolling bearing stationary installation is passed through on the support of oxidation trough both sides in rotating shaft 4 two ends.Originally the operation action principle of waste disposal plant that has weighting material biological drum (drum) is as follows: sewage flows into oxidation troughs 1 from water inlet pipe 3, because the effect of baffle plate 2 is separated into several parts to oxidation trough 1, makes the circuitous oxidation trough that flows through of sewage.The part of biological drum (drum) 6 is immersed in the sewage of oxidation trough 1, and rotates with certain speed.Alternately contact with air and sewage attached to the microbial film on the rotating cylinder (drum) 6, the organic pollutant during submergence in the absorption sewage absorbs the oxygen in the atmosphere when surfacing.Circulation makes the organic pollutant in the sewage obtain oxygenolysis under the effect of aerobic microbiological so repeatedly, and simultaneously, the microbial film on the biological drum (drum) 6 constantly comes off voluntarily, and the sewage after handling drains into settling tank to be separated.

The utility model compared with prior art has following advantage and beneficial effect: 1. owing to filled the design of needed suitable weighting material and reasonable flow channel in the biological drum (drum) of this device, thereby can give full play to the advantage of biomembrance process.Under same condition, to compare with existing blodisc waste disposal plant of the same type, its sewage treatment capacity and efficient can improve more than 1 times; 2. this apparatus structure compactness, floor space little, easy to manufacture, easy to maintenance, can reduce investment outlay 30%; 3. good, the power and energy saving of this waste disposal plant treatment effect is compared with the blodisc of existing same specification and can be saved the electricity charge about 40%; 4. there is not mud to accumulate can not resembling in the oxidation trough that has the blodisc waste disposal plant now in the oxidation trough of this device,, operates more easy so need not regular spoil disposal.

Below Figure of description is further specified as follows: Fig. 1 is that the structure of the waste disposal plant of biological drum (drum) with weighting material is formed synoptic diagram, and Fig. 2 is the structural representation of biological drum (drum), and Fig. 3 is that its (Fig. 2) A-A is to sectional view.1 is oxidation trough, and 2 is baffle plate, and 3 is water inlet pipe, and 4 are rotating shaft, and 5 is nut, and 6 for having the biological drum (drum) of weighting material, and 7 is sleeve, and 8 is rising pipe, and 9 is the rotating cylinder cover plate, and 10 is the rotating cylinder base plate, and 11 is cylinder, and 12 is projection, and 13 is screw, and 14 is gusset.

The utility model can be realized in the following manner: 1. by design shown in Figure 1, add each parts of cost device, wherein: the oxidation trough 1 of belt supporting frame, baffle plate 2, all available machine-tooled method processing and manufacturing of rotating shaft 4, the oxidation trough radius R can be 285mm, oxidation trough and support are welded into the oxidation trough of belt supporting frame, the baffle plate 2 that processes is fixedly welded in the groove, the baffle plate height can be 180mm, and water inlet pipe 3 and rising pipe 8 are fixedly welded on the bottom, left side of groove and the right upper portion of groove respectively; Rotating cylinder (drum) adopts the metal sheet offer a plurality of enough big holes to roll and be welded into cylinder (drum), cylinder 11 diameter phi can be 500mm, the long L of cylinder can be 210mm, rotating cylinder base plate 10 and cylinder welding, at many gussets 14 of tube internal fixing welding and a plurality of projection 12, sleeve passes cylinder and welds with the rotating cylinder outer wall is fixing, be filled on demand as various types of weighting materials such as cascade ring, Raschig rings in the tube, again the rotating cylinder cover plate 9 that processes formed detachable fixedlying connected by the interior projection 12 of screw 13 and tube with cylinder; 2. be connected and installed by the described interconnected relationship of top specification sheets then, and try out, just can realize the utility model preferably.
