Abstract

A lift microporosity aerator relates to an aeration used to make biochemical treatment to the effluent. The lift microporosity aerator overcomes the disadvantages of the prior aerator of inconvenience cleaning and repair, high price of the aeration head and the lower corrosion resistance. The utility model adopts that two turning joint pipes are connected into one lifting air supply pipe; the end branch pipe of the air supply pipe is provided with a plurality of micropore aeration heads made by the polyethylene plastic. The utility model not only has higher oxygen availability, but also has convenient cleaning and repair and low cost. The lift microporosity aerator is suitable for various systems which make biochemical treatment to the effluent.

Description

Lift microporosity aerator

The utility model relates to a kind of aerating apparatus that sewage is carried out biochemical treatment.

Existing micro-hole aerator is made up of steam line and aeration head, and aeration head is contained in the termination of steam line, and by being placed in the sewage lagoon, aeration head adopts the micro porous aeration head made from ABS plastic.Because the steam line and the aeration head of this device are to be fixedly mounted in the sewage lagoon, so its cleaning and maintenance are very inconvenient.Again because the price height of ABS plastic, so micro porous aeration head of making by ABS plastic, although the utilization ratio of oxygen is very high, but cost height, universal difficulty, and the micro porous aeration head of being made by ABS plastic is in benzene, vinyl acetic monomer muriate, acetone (10%) and high concentration ethanol chemical substances such as (95%), poor chemical stability is damaged easily.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of elevated micro-hole aerator is provided, and it has, and cleaning is easy to maintenance, cost is low, erosion-resisting characteristics.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is hoisting type micro-hole aerator structure iron during working order in sewage lagoon.

Fig. 2 is the structure iron of hoisting type micro-hole aerator when being lifted out the water surface.

Fig. 3 is a turning joint duct ligation composition.

Fig. 4 is the structure iron of micro porous aeration head.

The technical solution that the utility model is taked is, lift microporosity aerator is made up of steam line and aeration head, it is characterized in that: steam line is by being contained in straight tube (1) on the base (14) that is fixed on the sewage pool side, being contained in turning joint pipe (2) on the straight tube, being contained in bend pipe (16) on the turning joint pipe (2), being contained in bend pipe (4) on the bend pipe (16), being contained in turning joint pipe (13) on the bend pipe (4), being contained in the bend pipe (12) on the turning joint pipe (13) and the branch gas branch pipe (7) that is contained on bend pipe (12) termination forms; Be equipped with on the arm (7) and a plurality ofly have many microporous aeration heads (8) by what vinyon was made; A chain road groove (3) is housed on the bend pipe (16), a hook (17) is housed on the bend pipe (4), chain (18) hangs on the hook (17), and by chain road groove (3).

The turning joint pipe is made up of inner tube (26) and cover outer tube (21) on inner pipe, and ball is housed between the inner and outer pipes, in the both sides of ball sealing ring is housed. Be welded with level gear thick stick (19) at bend pipe (12) near elbow end place, be welded with a vertically gear thick stick (5) in the elbow of bend pipe (4).

The utility model has following advantage than prior art:

1, because micro-hole aerator can be lifted out the water surface, make that cleaning and maintenance aeration head are very convenient, do not need to drain sewage, just can clean and keep in repair.

2, the aeration head of being made by vinyon the aeration head oxygen utilization rate made from ABS plastic is much at one not only arranged, and cost is low, and erosion resistance is strong.

The utility model will be described in further detail in conjunction with the accompanying drawings.

In Fig. 1, straight tube (1) is installed on the supporting plate (15), and supporting plate is contained on the base (14) that is fixed on the cement pool side.One termination source of the gas of straight tube, the other end is equipped with turning joint pipe (2).Turning joint pipe and bend pipe (16) attaching, bend pipe (4) straight peen end is contained on the straight peen end of bend pipe (16) by ring flange, turning joint pipe (13) is housed on the elbow end of bend pipe (4), the elbow end of bend pipe (12) is contained on the turning joint pipe (13), divides gas branch pipe (7) to be contained in the straight peen end of bend pipe (12) by ring flange.Dividing gas branch pipe (7) is that arm by two levels is welded on the vertical pipe that has a ring flange and constitutes, and interface is welded with arm stiffening plate (11), and a drain plug (10) is equipped with in the bottom of vertical pipe.On the level pipe of a minute gas branch pipe (7), the uniform a plurality of aeration heads (8) that are equipped with, and a plurality of balance weight body (6) and two supports (9) are housed.Upward be welded with level retaining thick stick (19) at bend pipe (12), be welded with a vertically retaining thick stick (5) in the elbow of bend pipe (4) near elbow end place.Be welded with a chain road groove (3) in the elbow of bend pipe (16), be welded with a hook (17) at the straight peen end of bend pipe (4), a chain (18) hangs on the hook (17), and by chain road groove (3).

Hoisting type aerator shown in Figure 1 is its state when putting into sewage lagoon and working, air leads to aeration head from air-supply duct, emerges from the micropore of aeration head, the tiny bubble that forms in sewage lagoon, air is fully contacted with sewage, improved the utilization ratio of oxygen.When needs clean maintenance to aerator, the pulling chain, aerator just can be raised.Fig. 2 has represented that micro-hole aerator is lifted out the state of the water surface.Two retaining thick sticks (5,19) on the bend pipe have guaranteed when aerator is put into the pond, divide gas branch pipe (7) to swing backward, and the air-supply duct in water is remained in the plane.Drain plug (10) on the branch gas branch pipe (7) can be used for removing the ponding in the air-supply duct, makes maintenance more convenient.The support (9) that is contained on the branch gas branch pipe has guaranteed that aeration head has certain distance at the bottom of the pond, does not make foreign material such as silt at the bottom of the pond stop up micropore on the aeration head.

Fig. 3 has represented the structure of turning joint pipe, and the turning joint pipe is made up of interior pipe (26) and cover outer tube (21) on inner pipe.Two circle balls (25,27) are housed between the inner and outer pipe, a sealing-ring (20,23) respectively is equipped with in the outside at two circle balls, respectively have two fabrication holes that communicate with two circle ball grooves at outer tube, be screwed with sealed screw (24) on its hole, also have an oil hole (22) that communicates with two circle ball grooves on the outer tube.

Fig. 4 represents the structure of micro porous aeration head.Aeration head is made up of microporous pipe (29), the loam cake (28) that is contained in the microporous pipe two ends and lower cover (32), two sealing-rings (31,34) between microporous pipe (29) and loam cake and lower cover, pull bar (30) passes from the centre hole of upper and lower two lids, and tighten upper and lower cover with nut (33) at the pull bar two ends.The loam cake end is contained on the branch gas branch pipe (7).Microporous pipe (29) is made by polythene material.
