Abstract
The utility model discloses an oxygen supply type sludge thickener, belongs to environmental protection equipment, and aims to provide a sludge thickener capable of preventing the release of phosphorous-containing substances in discharged sludge. The oxygen supply type sludge thickener comprises a tank of which the bottom is shaped like a pot bottom, a water gathering weir which is fixed in the tank and shaped in an annular groove structure, a water outlet pipe communicated with the water gathering weir, a filter plate fixed at the bottom of the tank, and a sludge feed pipe and a sludge discharge pipe which are located above and under the filter plate, respectively, wherein a center cylinder (12) communicated with the sludge feed pipe (2) is arranged in the tank (1); a second filter plate (6) is fixed in the center cylinder; and a plurality of aeration heads (5) communicated with a gas inlet pipe (3) are arranged above the second filter plate (6) and the filter plate (7). The oxygen supply type sludge thickener is capable of stirring sludge to achieve the purposes of sufficient aerating oxygen supply and circulating sedimentation; and therefore, the formation of an anaerobic environment due to sludge deposition is effectively avoided; and the oxygen supply type sludge thickener is the environmental protection equipment for treating wastewater sludge.
Description
Technical field
The utility model relates to a kind of sludge thickener, relates in particular to a kind of sludge thickener of oxygen supply continuously; Belong to environmental protection equipment.
Background technology
At present, sludge thickener conventionally by bottom be pan bottom shape pond body, be fixed on this Chi Tizhong be circular water collecting dike, the rising pipe being communicated with this water collecting dike, be fixed on filter plate at the bottom of pond, lay respectively at this filter plate upper and lower enter mud pipe and shore pipe forms; Due to aerating apparatus being set, mud easily at the bottom of being deposited on pond and form anaerobic environment, causes the dephosphorization bacterial in mud to decompose intracellular poly-phosphate and discharge phosphorus, causes the mud cake phosphorus content after dehydration too high, does not reach emission standard.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide a kind of oxygen-supplying type sludge thickener that in mud, phosphorus containg substances discharges that prevents from discharging.
To achieve these goals, the utility model is by the following technical solutions: it comprise bottom be the pond body of pan bottom shape, be fixed on water collecting dike, the rising pipe being communicated with this water collecting dike that this Chi Tizhong is annular groove shape structure, be fixed on filter plate at the bottom of pond, lay respectively at this filter plate above and below enter mud pipe and shore pipe; Chi Tizhong has and the central tube that enters mud pipe and be communicated with, and is fixed with the second filter plate in this central tube, and all there are the some aeration heads that are communicated with inlet pipe the top of the second filter plate and filter plate.
The outer mud cover that is with of central tube; There is the horn-like cloth cover that is fixed on central tube bottom the below of mud cover.
Compared with the prior art, the utility model is owing to having adopted technique scheme, on the basis of traditional structure, increased central tube, and in central tube and at the bottom of pond, increased TSA device, therefore can stir mud and make its abundant aeration oxygen supply, circulation precipitation, thereby effectively avoid producing anaerobic environment because of sludgd deposition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: pond body 1, enter mud pipe 2, inlet pipe 3, shore pipe 4, aeration head 5, the second filter plate 6, filter plate 7, cloth cover 8, support 9, rising pipe 10, ponding weir 11, central tube 12, mud cover 13.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: the bottom that is pan bottom shape at pond body 1 is fixed with filter plate 7, the top of this filter plate is fixed with the some aeration heads 5 that are communicated with inlet pipe 3, the below of this filter plate is fixed with shore pipe 4; At pond body 1 inwall, near the position of Chi Kou, be fixed with the water collecting dike 11 of annular groove shape structure, the bottom of this water collecting dike is distributed with some through holes, and the rising pipe 10 being fixed on pond body 1 is communicated with water collecting dike 11.The mud pipe 2 that enters being fixed on pond body 1 stretches in the central tube 12 being fixed in pond body 1, is fixed with the second filter plate 6 in this central tube, and the top of this second filter plate is fixed with the other a plurality of aeration heads 5 that are communicated with inlet pipe 3.
For fear of the aeration head 5 that is arranged in central tube 12, stir mud and make its diffusion, impact precipitation, mud cover 13 is fixed on the periphery of central tube 12 by support 9.For at the bottom of the mud that guarantees to overflow from central tube 12 can evenly slowly be deposited in pond, also in order to prevent the mud floating at the bottom of pond, below mud cover 13, there is the horn-like cloth cover 8 that is fixed on central tube 12 bottoms simultaneously.
Claims (3)
1. an oxygen-supplying type sludge thickener, comprise bottom be the pond body of pan bottom shape, be fixed on water collecting dike, the rising pipe being communicated with this water collecting dike that this Chi Tizhong is annular groove shape structure, be fixed on filter plate at the bottom of pond, lay respectively at this filter plate above and below enter mud pipe and shore pipe; It is characterized in that: in pond body (1), have and the central tube (12) that enters mud pipe (2) and be communicated with, be fixed with the second filter plate (6) in this central tube, all there are the some aeration heads (5) that are communicated with inlet pipe (3) top of the second filter plate (6) and filter plate (7).
2. oxygen-supplying type sludge thickener according to claim 1, is characterized in that: the outer mud cover (13) that is with of central tube (12).
3. oxygen-supplying type sludge thickener according to claim 1 and 2, is characterized in that: there is the horn-like cloth cover (8) that is fixed on central tube (12) bottom the below of mud cover (13).
