Description

A kind of novel normal pressure water-storing tank

Technical field

This utility model relates to water treatment field, especially the water storage device in sewage disposal.

Background technology

It is known that water tank applies to feedwater, draining, purification of water quality, sewage treatment plant widely, is the device systems of the industry engineerings such as oil, power plant, weaving, papermaking, medical science.In sewage disposal process, primarily serving two effects, one is that this part is primarily to avoid bringing negative pressure to pipe network, water shortage when avoiding force (forcing) pump to work simultaneously for pressurization；Second is to store water, including the middle water processed in technological process.In waste water processes, need to be processed through next step again by the water through preliminary treatment or need as former water, it is separately made purposes, it is often necessary to arrange a water tank, play the effect of water storage.

Existing gerotor type water tank, major part does not takes into account inner air and outer air on exhaust apparatus and circulates on the impact of water quality in water tank, and discharge duct opens wide for a long time, when water tank inner air and outer air occurs exchange, usually can pollute water tank inner air.Also changing water tank upper gas into pure nitrogen gas to seal, the method cost is more expensive, and the highest to the reliability requirement of safety measure, and misoperation or device are likely to result in device explosion time malfunctioning.Have much room for improvement.

Utility model content

This utility model is for the deficiencies in the prior art, it is provided that a kind of favorable sealing property and pollution-proof performance are good, and technique is simple, and operation possibility is high, and cost is relatively low, the suitable novel normal pressure water-storing tank gone into operation.

nullFor realizing this utility model purpose，Provide techniques below scheme: a kind of novel normal pressure water-storing tank，It is characterized in that including casing、The inside and outside cat ladder being arranged on casing、It is arranged at the manhole on casing top，The nearly top of casing is provided with water inlet pipe，The nearly bottom of casing is provided with outlet pipe and blow-down pipe，Dosing pump and electromagnetic valve it is provided with on water inlet pipe，Electromagnetic valve it is provided with on blow-down pipe，Casing top is provided with exhaust apparatus，Exhaust apparatus includes vertical exhaustor、Blow-off tee pipeline，Blow-off tee pipeline includes being connected bottom with vertical gas exhaust tube flange、Vertical end and horizontal ends，Vertical end connects a mouth of pipe bend pipe straight down，The junction of a number bend pipe and vertical end is set to a funnel-form body，A ball it is placed with in a number funnel-form body，A number ball diameter is more than the path of a funnel-form body，Maximum diameter less than a funnel-form body，Horizontal ends connects No. two bend pipes straight down，The downward mouth of pipe of No. two bend pipes is set to No. two funnel-form bodys，No. two balls it are provided with in No. two funnel-form bodys，No. two ball diameters are more than the path of No. two funnel-form bodys，Maximum diameter less than No. two funnel-form bodys.

As preferably, the mouth of pipe of a bend pipe and No. two bend pipes is provided with grenadine and air filter cloth.

As preferably, water tank entirety uses not 304 rust steel steel plate.Having the intensity of super Zhuo, sidewall is without cross weld, it is simple to clean；304 corrosion resistant plates have stronger rotproofness；Full welding scene combination, good airproof performance, it is ensured that water quality is not by secondary pollution.

As preferably, No. one and No. two balls are quality of rubber materials.

This utility model beneficial effect: exhaust apparatus of the present utility model, when water tank water intake, water level rises, in water tank, air is compressed, and when pressure is more than external pressure, a ball is i.e. backed down, a number ball produces space with pipeline opening, and in water tank, air obtains and arranges in addition.When water tank water outlet and emptying, water level decreasing in water tank, need extraneous air to enter to balance inside and outside differential pressure, now big in outside atmosphere pressure ratio water tank, No. two balls are upwards pushed up, and produce gap between funnel and No. two balls, and air is passed into water tank.In exhaust apparatus, two mouths of pipe are all downward, and when being possible to prevent weather conditions the best, rain etc. fall into pipeline, cause the pollution of water in water tank.In addition, when water tank serves as water storage device standing, two balls all fall within bell mouth, block the mouth of pipe, completely cut off the circulation of water tank outside air, formed and close, one environment extremely sealed of feed-tank, in i.e. avoiding water tank, water body is polluted by extraneous air.
