Description

A kind of rotating biological contact filtering material

The utility model relates to mechanical, particularly a kind of rotating biological contact filtering material that is used for field of waste water treatment.

At present, along with expanding economy, the waste water output in city also increases thereupon, in order to reach requirement on environmental protection, waste water all will be handled, after reaching environmental requirement, can discharge, wastewater treatment is generally carried out organic decomposition with aerobe method, and aeration is exactly in order to be pressed into air in waste water, and extensively be piled up in the aerator tank with fixed contact filtering material lamination at present, fixed contact filtering material can not drift moving with the aeration agitate water in the aerator tank, makes its surface biological film hyperplasia plumpness through long-time aeration, makes aeration current internal recycle speed slowly or block, cause the inner microbial film of filter material to obtain oxygen and anaerobic digestion takes place microbial film is peeled off, cause water quality deterioration; And another kind of floating type filter material commonly used can fly on the liquid level less than pending waste water event owing to proportion, and pushes the hillock that forms similar iceberg mutually, and it can't fully be contacted with waste water, and it is stable that the speed that purifies water can't keep.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned filter material commonly used, and a kind of rotating biological contact filtering material is provided, to improve the purification or the speed of cooling of waste water or waste gas and cooling tower.

The technical solution of the utility model.

The utility model is to be laid with most curved blades that double-deck forward and backward staggered corner cut is 30 degree outside the circular central siphon of a hollow, wherein the thickness of front side curved blade increases progressively from front to back with 1: 3 ratio, the thickness of rear side curved blade then successively decreases from front to back with 3: 1 ratio, and is provided with circular ring one on the peripheral intersection of forward and backward curved blade.

Describe structure of the present utility model and embodiment in detail below in conjunction with accompanying drawing:

Fig. 1 is a three-dimensional appearance synoptic diagram of the present utility model.

Fig. 2 looks synoptic diagram for master of the present utility model.

Fig. 3 is an enforcement illustration of the present utility model.

Fig. 4 is that of the present utility model another implemented illustration.

(1) be that contact filtering material, (11) are that rectangular element, (B) for treatment trough, (2) be round bar for rear side curved blade, (14) for circular ring, (A) for front side curved blade, (13) for circular central siphon, (12), (3) are that water pump, (31) are that gas blower, (41) are that inlet mouth, (1B) for venting port, (5) for air feeder, (51) for air-supply conduit, (6) be water pump, (61) for send water conduit for spacing hole, (C) for exhaust gas treating tower, (1A) for air-supply conduit, (411) for connecting pipeline, (311) for spacing hole, (4).

Shown in accompanying drawing 1, accompanying drawing 2, the utility model is the circular central siphon (11) in a hollow Being laid with double-deck forward and backward staggered corner cut outward is 30 most curved blades (12), (13) of spending, Wherein the thickness of front side curved blade (12) increases progressively from front to back with 1: 3 ratio, and the rear side circle The thickness of arc blade (13) then successively decreases from front to back with 3: 1 ratio, and at forward and backward circular arc leaf The peripheral intersection of sheet (12), (13) is provided with one circular ring (14).

Below in conjunction with accompanying drawing 3 embodiment of the present utility model is described:

As shown in Figure 3, a most contact filtering material (1) can be penetrated in its circular central siphon (11) by a round bar (2) and be chained together, the bridge joint that is parallel to each other again becomes rectangular element (A), insert on the water surface of biological wastewater treatment groove (B) (aerator tank), in the following space, and the effluent sewage of treatment trough (B) bottom is extracted out to cocycle by lift pump (3), evenly be sprayed on the contact filtering material (1) with the spacing hole of being offered by its connecting pipeline (31) (311), spacing hole (411) on the air-supply conduit (41) that connects by the gas blower (4) of impulsive force and bottom side upwards blows contact filtering material (1) and rotates, remove the aging mud that adheres on it to throw, control exceedingly increases the blockage problem that causes because of biological bacteria; In use, because before the contact filtering material (1), back staggered curved blade (12), (13) not overlapping and be the design of reporting to the leadship after accomplishing a task, make the wind-force that blows on the gas blower (3) to curved blade (12), (13) meeting produces the tangent line component of a rectilinear axial line, and can prevent sinuous flow, and then this tangent line component will on average promote curved blade (12), (13) two lateral lobe walls are around the axial line rotation of rounding bar (2), in addition, be staggered front to back the curved blade (12) of arrangement, (13) because thickness is with design in reverse 3: 1, can reduce its windage, and it is long-pending to increase its surface in contact, to improve the speed that purifies.

Fig. 4 is applied to enforcement illustration in the exhaust gas treating tower for the utility model, exhaust gas treating tower (C) is a Y body, inlet mouth (1A) and venting port (1B) that its top laterally is connected for V-arrangement, its handing-over bottom then is connected with a water port (1C) longitudinally, its principle of work is, a most contact filtering material (1) are penetrated in its circular central siphon (11) by a round bar (2) and are chained together, in the V-arrangement cross connection space of inserting exhaust gas treating tower (C), at this moment, through air-supply conduit (51) air is sent into inlet mouth (1A) by air feeder (5), and blow filter material (1) and rotate, evenly be sprayed on the filter material (1) through sending water conduit (61) that the washing water of bottom are extracted out to cocycle by Water-pumping motor (6) in addition, remove dust dirt attached thereto to throw, vaporous dirt makes clean gas be discharged by venting port (1B).

The utility model can be used in the cooling tower, and contact filtering material (1) can rotate voluntarily to the current that spray, and prolongs the residence time, and it is long-pending to increase surface in contact, makes cooling performance better, can eliminate the disease hotbed.

This reality has novel texture simple, can improve wastewater treatment speed, prevent that aerator tank from stopping up.
