Abstract
The utility model relates to a device for the gas stripping between a biochemical pool and a secondary sedimentation tank and belongs to a device of a sewage treatment system. The device can convey sludge in the secondary sedimentation tank to the biochemical pool and is used for solving the problems that the operation is complicated, the conveying efficiency is low, and the sludge is difficult to be conveniently and effectively conveyed due to the fact that the sludge in the secondary sedimentation tank is conveyed to the biochemical pool by usually adopting a conveying pump currently. The device is characterized by comprising the biochemical pool, the secondary sedimentation tank, a compressed air pipe, a compressed air pipe valve and a sludge return pipe, wherein the lower end of the sludge return pipe is fixed at the bottom of the secondary sedimentation tank, the upper end of the sludge return pipe is fixed at the upper part of the biochemical pool, the lower end of the compressed air pipe is fixed at the lower part of the sludge return pipe, and the compressed air pipe valve is mounted in the compressed air pipe. The device for the gas stripping between the biochemical pool and the secondary sedimentation tank has the advantages of reasonable structural design, simplicity in operation and high sludge conveying efficiency.
Description
Technical field
The utility model relates to a kind of air-lift device, especially relates to a kind ofly for the air-lift device between biochemistry pool and the second pond, belongs to a device in the Sewage treatment systems, the mud in the second pond can be transported in the biochemistry pool.
Background technology
In sewage treatment process, mud in the second pond need to be transported in the biochemistry pool, usually adopt at present transferpump that the mud in the second pond is transported in the biochemistry pool, complicated operation, transport efficiency is low, be difficult to convenience, effectively mud carried, when especially the height of biochemistry pool was higher, the conveying difficulty of mud was larger, in addition, maintenance expense to transferpump is high, thereby has reduced the overall performance of a whole set of Sewage treatment systems.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is simple to operate, to the transport efficiency of mud high be used for air-lift device between biochemistry pool and the second pond.
The technical scheme in the invention for solving the above technical problem is: the constructional feature that should be used for the air-lift device between biochemistry pool and the second pond is: comprise biochemistry pool, second pond, compressed air pipe, pressurized air pipe valve and mud return line, the lower end of described mud return line is fixed on the bottom of second pond, the upper end of this mud return line is fixed on the top of biochemistry pool, the lower end of described compressed air pipe is fixed on the bottom of mud return line, and described pressurized air pipe valve is installed in the compressed air pipe.
As preferably, mud return line described in the utility model is stainless steel.
As preferably, compressed air pipe described in the utility model is stainless steel.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, dependable performance, can make things convenient for, effectively the mud in the second pond is transported in the biochemistry pool by pressurized air, the mud that is arranged in second pond bottom enters mud return line from the lower end of mud return line, then upwards carries along mud return line, at last from the output of the upper end of mud return line, thereby so that mud enter in the biochemistry pool.Air-lift device in the utility model greatly facilitates the mud in the second pond is transported in the biochemistry pool, is conducive to promote the performance of sludge treating system.
Description of drawings
Fig. 1 is the structural representation that is used for the air-lift device between biochemistry pool and the second pond among the utility model embodiment.
Fig. 2 be Fig. 1 get the bid be marked with that pressurized air flows to structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 2, the air-lift device that is used between biochemistry pool and the second pond in the present embodiment comprises biochemistry pool 1, second pond 2, compressed air pipe 3, pressurized air pipe valve 4 and mud return line 5, wherein, mud return line 5 is stainless steel, and compressed air pipe 3 is stainless steel.
The lower end of the mud return line 5 in the present embodiment is fixed on the bottom of second pond 2, so that the mud that is positioned at second pond 2 bottoms can be transferred out by mud return line 5.The upper end of the mud return line 5 in the present embodiment is fixed on the top of biochemistry pool 1, so that mud can be transported in the biochemistry pool 1 by mud return line 5.The top of the bottom of said second pond 2 and biochemistry pool 1 all belongs to prior art for a person skilled in the art in the utility model, no longer describes in detail herein.
The lower end of the compressed air pipe 3 in the present embodiment is fixed on the bottom of mud return line 5, and pressurized air pipe valve 4 is installed in the compressed air pipe 3.
The air-lift device that is used between biochemistry pool and the second pond in the present embodiment can be transported to the mud of second pond in the biochemistry pool, during use, pressurized air pipe valve 4 is opened, extraneous pressurized air can enter in the compressed air pipe 3, compressed-air actuated air pressure is generally about 0.1kg, this pressurized air passes through compressed air pipe 3 and mud return line 5 successively, under compressed-air actuated effect, the mud of second pond 2 bottoms can be transported in the mud return line 5, these mud upwards flow along mud return line 5, enter at last biochemistry pool 1, thereby reach the purpose that submits mud.
In addition, need to prove, the specific embodiment described in this specification sheets, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification sheets only is to the explanation of the utility model structure example.Allly conceive equivalence variation or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
