Abstract
本实用新型属于污水处理领域的设备。为克服已有技术中的多种曝气器均无止回阀的缺陷特提出本方案——带有止回阀的污水处理曝气器。它是由马鞍桥、止回阀阀座、阀芯所组成。马鞍桥与支气管粘接并接通，阀座的内孔含有锥面部分，阀芯的表面也有与其配合的锥面部分，阀芯阀座间为松动的配合，马鞍桥用上部的螺纹与曝气器连接。正常工作时，支气管内被鼓风机压缩的空气经阀芯、带输气孔的安装螺丝送入曝气器内，经带微孔的曝气模板吹出。偶遇鼓风机仃转时，回水进入曝气器内将止回阀关闭，避免过多的水进入支气管内造成鼓风机再启动时的困难。本方案具有结构简单、制造成本低、工作稳定的优点，能保证设备正常运转。
The utility model belongs to equipment in the field of sewage treatment. In order to overcome the defect that various aerators in the prior art do not have check valves, this proposal is proposed—a sewage treatment aerator with a check valve. It is composed of saddle bridge, check valve seat and valve core. The saddle bridge is bonded and connected to the bronchus. The inner hole of the valve seat contains a conical surface, and the surface of the valve core also has a conical surface that matches it. The valve core and valve seat are loosely fitted. Gas connection. During normal operation, the air compressed by the blower in the bronchus is sent into the aerator through the valve core and the mounting screw with air delivery holes, and blown out through the aeration template with micro holes. Occasionally, when the blower stops running, the return water enters the aerator to close the check valve, so as to avoid the difficulty when too much water enters the bronchus and causes the blower to restart. The solution has the advantages of simple structure, low manufacturing cost and stable operation, and can ensure the normal operation of the equipment.
Description
Technical field:
The utility model belongs to the equipment of sewage treatment area.It is specifically related to a kind of structure that has the aeration in sewage treatment device of vacuum breaker.
Background technology:
Aerator is the key equipment that modern society handles contaminated waste water, and sewage after reaching the purification standard of country after precipitation and the processing of oxygen blast aeration, discharges in river or lake, to guarantee the cleaning of water system in a plurality of biochemistry pools again.It is Britain Bo Fuer aerator that general sewage work used more, also useful home-made aerator product, used various aerator common characteristic are all not have vacuum breaker, when not working, motor can not prevent that large amount of sewage from flowing backward in the segmental bronchus, when gas blower is restarted, breathe heavily shake, can cause the damage of equipment when serious because of the especially big formation of load.Therefore be provided with and prevent that the sewage backflow measure from just putting on the agenda, must solve.
Summary of the invention:
The purpose of this utility model is for overcoming the technical problem that exists in the existing aerator and guaranteeing to make aerator special this programme that proposes of works better for a long time---have the aeration in sewage treatment device of vacuum breaker, it is that vacuum breaker is arranged in the saddle bridge, and it has function-stable and characteristic of simple structure.
By as above design, the aeration in sewage treatment device that has vacuum breaker that this programme proposed, include the aerator of sewage disposal, it is characterized in that it is made of saddle bridge, valve seat and spool, valve seat is fixedlyed connected with the saddle bridge, inside has the hole that contains the conical surface, and the conical surface on the spool and the conical surface of valve seat match, and valve seat is loosening cooperating with spool.
In this programme, the lower surface of its saddle bridge is that cylindrical surface and bronchial outside surface match and merge bondingly, and the endoporus of upper end is connected with aerator with screw thread.
Adopt this programme can embody following superiority: aerator is the bottom that is contained in the biochemistry pool of sewage disposal, have 4～6 meters dark, aerator is connected connection by the saddle bridge with segmental bronchus, during works better, gas blower enters a plurality of segmental bronchuses with the air that bloats through main air duct, enters a plurality of aerators again, and the aeration lamina membranacea through being with micropore blows out, form a large amount of small bubbles, carry out the oxygen exchange with water.When because of some reason gas blower interruption work, sewage flows backwards at leisure and enters in aerator and the segmental bronchus, after gas blower starts once more, the wind with certain pressure that bloats is if will discharge sewage apace from aerator, then must run into great resistance, make whole plant the shake phenomenon occur breathing heavily, can damage parts when serious.Had vacuum breaker just can avoid large amount of sewage to flow backward to phenomenon in the segmental bronchus, assurance equipment can normally move.It also has simple in structure, advantage of low manufacturing cost.
Description of drawings:
Fig. 1 is the structural representation that this programme has the aeration in sewage treatment device of vacuum breaker.
Embodiment:
Aerator is the key equipment in the sewage treatment process.All do not have vacuum breaker and have special this programme that proposes of problem of sewage refluence phenomenon when changeing in that gas blower is left alone without help for solving multiple existing aerator.It is made up of saddle bridge 1, valve seat 2, spool 3, the lower surface of saddle bridge is cylindrical, match with segmental bronchus 4, bonding and connect, the valve seat of vacuum breaker is fixedlyed connected with the saddle bridge, the endoporus of valve seat has cone surface, the part that matches with cone surface on the valve seat is also arranged on the spool, be loosening cooperation between spool and the valve seat.The top of saddle bridge is connected with aerator with screw thread, the top of aerator is an aeration lamina membranacea 5 that has micropore, delivered in the aerator through the installation screw 6 of segmental bronchus, vacuum breaker, middle band transfer port by the air that gas blower compresses, gas blows in the sewage that is cleaned operation through the aeration lamina membranacea.During works better, what aerators are worked simultaneously, and the water that back-pressure is returned after changeing because of some reason gas blower is left alone without help can make closure of check ring, has avoided a large amount of water to enter into segmental bronchus, creates working conditions preferably when starting once more for gas blower.
The pilot sample of this programme proves after on probation: it has reliable operation, simple in structure, advantage of low manufacturing cost, has solved the problem of the sewage refluence of long-time existence, has improved working efficiency, and aerator can be worked stably and normally.
