Description
Technical field
The utility model is related to a kind of Air Weir more particularly to a kind of SBR ponds Air Weirs, belong to matching for sewage disposal device
Set machinery.
Background technology
The draining in traditional SBR ponds is generally carried out with water decanter, and as water decanter lifts, SBR ponds lift therewith, so as to
Reduce basin's effective volume and utilization rate of equipment and installations.And traditional water decanter intermittent drainage, therefore, it is difficult to improve its degree of automation.
China Patent No. 01253138.3 discloses a kind of Drain air weirs, it is by draining weir groove, airhood, triangular-notch weir
Plate forms, and triangle weir plate is threaded on draining weir groove, and the draining weir groove and airhood are fixedly mounted, on draining weir groove
It is also equipped with an automatic control box.For the technical solution compared with traditional SBR ponds drainage arrangement, it is fixedly mounted on high water level
On, SBR ponds can be made to expire pond operation always.And can realize continuous drainage, equipment is durable, repair is easy, can also be by certainly
Dynamic control cabinet realizes operation automation.But the equipment is susceptible to siphonage, siphon in drainage procedure when displacement is big
It is to be easy to cause sludge to bring in water outlet that the effluent quality that makes is unqualified into, causes unnecessary trouble.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact-sized, solves existing skill
Air Weir present in art is susceptible to water outlet siphonage, and water outlet siphon sludge can be prevented to enter the novel air of weir body
Weir, while increase installation and adjustment seat, convenient for a kind of SBR ponds Air Weir of the Level tune installation of equipment.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
A kind of SBR ponds Air Weir, including weir body, the weir body top is surrounded by triangle water outlet weir plate, described
The rake tooth of inner concavity is equipped in triangle water outlet weir plate, the top of the weir body is equipped with pressure shield, the bottom of the weir body
Equipped with the weir body discharge outlet being connected with weir body, spoiler is equipped in the weir body discharge outlet.
It is relatively low to civil engineering requirement when equipment is installed, after being placed to good position, adjusting bolt regulating weir body entirety can be passed through
It is horizontal.After installing, air bleeding valve is closed, opens intake valve, pressure rise in the body of weir, water cannot be introduced into weir body, work as intake valve
When closing air bleeding valve opening, the air pressure in pressure shield continuously decreases, and pressure continuously decreases.Water passes through weir body and pressure from weir body both sides
Water inlet between power cover enters, and is discharged from discharge outlet.Moment flow is big during due to starting, and occurs during air capacity deficiency in the body of weir
Occurs siphonage at discharge outlet, spoiler directly destroys water outlet siphon at this time, uses water steadying, ensures effluent quality.
Preferably, the edge of the pressure shield is in flange shape and is separately positioned with the external wall in weir, the pressure
The top of cover is equipped with the intake valve and air bleeding valve being connected with weir body, and the diameter of the air bleeding valve is more than the diameter of intake valve.
Ensure the supplement of connection atmospheric air amount when air bleeding valve is opened when water yield is big, avoid occurring negative pressure formation siphon in the body of weir, together
When intake valve may be selected to meet air inflow, it is cost-effective.
Preferably, the bottom of the spoiler and the bottom of weir body discharge outlet are in same level EDS maps, it is described
Extend weir body bottom in the top of spoiler.
Preferably, the bottom of the weir body is equipped with several adjustable installation and adjustment seats, the height of the installation and adjustment seat
Degree is less than the height of weir body.Requirement to civil engineering reduces, and horizontal problem occurs in when installation, can be by adjusting bolt come regulating weir body
Integral level, ensure water outlet be evenly distributed with.Installation and adjustment seat is divided into two parts, upper part weldering and weir body bottom, lower part with it is upper
Part is connected by screw bolts, and connecting hole uses slot.
Weir body is set under the water surface, and higher than the low water level water face.Water has difference in height institute shape by two ponds
Into pressure differential, realize pressure, water is put into low water level pond.
Spoiler ensure that when there is siphonage, and spoiler can destroy siphonage in time.
Therefore, a kind of SBR ponds Air Weir of the utility model, it is simple in structure, it is easy to operate, performance is improved, is had
Tunable performance.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the side structure schematic view of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment 1：As depicted in figs. 1 and 2, a kind of SBR ponds Air Weir, including weir body 1, the four of 1 top of weir body
Week is equipped with triangle water outlet weir plate 2, is equipped with the rake tooth 3 of inner concavity in the triangle water outlet weir plate 2, the weir body 1 it is upper
Side is equipped with pressure shield 4, and the bottom of the weir body 1 is equipped with the weir body discharge outlet 5 being connected with weir body 1, the weir body draining
Spoiler 6 is equipped in mouth 5.
The edge of the pressure shield 4 in flange shape and separately being positioned with 1 outer wall of weir body, the pressure shield 4 it is upper
Portion is equipped with the intake valve 7 being connected with weir body 1 and air bleeding valve 8, and the diameter of the air bleeding valve 8 is more than the diameter of intake valve 7.
The bottom of the spoiler 6 is with the bottom of weir body discharge outlet 5 in same level EDS maps, the spoiler 6
Top extend 1 bottom of weir body.
The bottom of the weir body 1 is equipped with several adjustable installation and adjustment seats 9, and the height of the installation and adjustment seat 9 is less than
The height of weir body 1.
The structure is in use, water is entered from weir body both sides by the gap of weir body and pressure shield, and is discharged from discharge outlet.Weir
Body is set under the water surface, and higher than the low water level water face.The pressure differential that water has difference in height to be formed by two ponds,
It realizes pressure, water is put into low water level pond.When intake valve opens exhaust valve closure, pressure rise in the body of weir, water cannot be introduced into
Weir body, when intake valve, which closes air bleeding valve, to be opened, pressure declines in the body of weir, and water enters weir body and discharged from discharge outlet, is vented simultaneously
Valve opening ensures atmosphere, supplements the pressure of weir physical efficiency, prevents negative pressure and cause siphonage, siphon such as occur and show
Even if the spoiler as rear water outlet destroys siphonage, ensure water steadying, do not influence effluent quality.
