Abstract
The utility model relates to environmental-protection equipment, in particular to an SBR (Sequencing Batch Reactor Activated Sludge) pool air weir, comprising a weir body, a pressure cover, a weir body water outlet and an air inlet valve. The air weir is characterized in that the pressure cover covers the upper part of the weir body, both sides of the pressure cover are arranged outside the weir body, the weir body water outlet is communicated with one low-water-level pool, a water outlet of the weir body water outlet is positioned below the water surface of the low-water-level pool, a plurality of layers of inversely V-shaped slots are respectively arranged among the pressure cover and both sides of the weir body, the tops of the inversely V-shaped slots are provided with water inlets, and the layers of inversely V-shaped slots are staggered and arranged. The utility model realizes the novel air weir which has simple structure and can prevent silt from entering the weir body.
Description
Technical field
The utility model relates to a kind of environmental protection equipment, especially relates to a kind of SBR Chi Kongqiyan.
Background technology
The draining in traditional SBR pond is generally carried out with straining hydrophone, and along with straining the hydrophone lifting, the lifting thereupon of SBR pond is held and utilization rate of equipment and installations thereby reduced effective pond.And therefore traditional hydrophone intermittent drainage of straining is difficult to improve its automaticity.Application number is that 01253138.3 utility model discloses a kind of Drain air weirs, it is made up of draining weir groove, airhood, triangle weir plate, the triangle weir plate is threaded on the draining weir groove, and an automatic control box also is equipped with in described draining weir groove and airhood fixed installation on the draining weir groove.This technical scheme is compared with traditional SBR pond dewatering installation, and it is fixedly mounted on the high water level, can make the SBR pond expire the pond operation all the time.And can realize continuous drainage, equipment is durable in use, maintenance is easy, can also realize operation automation by automatic control box.But this equipment is in drainage procedure, and the silt in the pond enters the weir body along with current easily, and deposits in the body of weir, makes it often to arrange sand, causes unnecessary trouble.
Summary of the invention
The utility model mainly is to solve existing in prior technology air weir to advance husky technical problem easily, provides a kind of simple in structure, can stop silt to enter the novel air weir of weir body.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel air weir, comprise weir body, pressure shield, weir body outfall, admission valve, it is characterized in that described pressure shield covers in body top, weir, the external side in weir is located in its both sides, described weir body outfall is connected with a low water stage pond, its delivery port is under the water surface in described low water stage pond, be respectively equipped with the reverse V-shaped groove of several layers between pressure shield and the body both sides, weir, the top of this reverse V-shaped groove is provided with water inlet, the interlaced arrangement of each layer V-type groove.When admission valve cut out, the air pressure in the pressure shield reduced gradually, and pressure reduces gradually.Water enters from the water inlet of body both sides, weir by reverse V-shaped groove top, and discharges from outfall.Bringing the silt that comes into by current is subjected to various reverse V-shaped grooves and stops and be difficult to pass through water inlet.Work as INO, silt is got back in the pond under gravity and gas pressure.Therefore silt is difficult for entering the weir body.
As preferably, described V-type groove has four layers.Silt has not substantially had to have entered into the weir body by the precipitation of four layers of V-type groove.
As preferably, two upper lateral parts of described weir body are provided with the triangle weir plate.The glassware for drinking water that the triangle weir plate is gone into the weir body to water has cushioning effect.
As preferably, the weir body is located under the water surface, and is higher than the described low water stage pond water surface.Water has the formed pressure differential of difference in height by two ponds, realizes pressure, and water is put into the low water stage pond.
As preferably, described water inlet is the gap between the frid of V-type groove both sides.This design scheme has guaranteed to have enough water intake velocity.
The beneficial effect that brings of the present utility model is, solved existing in prior technology air weir and advanced husky technical problem easily, realized a kind of simple in structurely, can stop silt to enter the novel air weir of weir body.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of structural representation of the present utility model; Accompanying drawing 2 is a kind of structural representations of the present utility model.The utility model is a kind of novel air weir, comprise weir body 2, pressure shield 1, weir body outfall 6, admission valve 3, two upper lateral parts of weir body are provided with triangle weir plate 4, pressure shield covers in body top, weir, the external side in weir is located in its both sides, described weir body outfall is connected with a low water stage pond, its delivery port is under the water surface in described low water stage pond, be respectively equipped with four layers of reverse V-shaped groove 5 between pressure shield and the body both sides, weir, has the gap between the frid of reverse V-shaped groove both sides, this gap is as water inlet, the interlaced arrangement of each layer V-type groove.The weir body is located under the water surface, and is higher than the described low water stage pond water surface.
When this structure was used, water entered by the gap between the frid of reverse V-shaped groove both sides from body both sides, weir, and discharges from outfall.The weir body is located under the water surface, and is higher than the described low water stage pond water surface.Water has the formed pressure differential of difference in height by two ponds, realizes pressure, and water is put into the low water stage pond.Bringing the silt that comes into by current is subjected to various reverse V-shaped grooves and stops and be difficult to pass through water inlet.Work as INO, silt is got back in the pond under gravity and gas pressure.Therefore silt is difficult for entering the weir body.
So the utlity model has simple in structurely, can stop silt to enter the characteristics such as weir body.
