Abstract

The utility model relates to a low-energy-consumption siphon water decanter, which consists of an exhaust valve, an exhaust pipe, a main drain pipe, an upper siphon pipe, a retractable hose, a limiting support, a lower siphon pipe and a buoy, wherein the exhaust valve is connected with the main drain pipe at the central part of the water decanter through the exhaust pipe, the lower end of the maindrain pipe is connected with the lower siphon pipe, the upper end of the main drain pipe is connected with the upper siphon pipe and the buoy is arranged at the lower part of the main drain pipe. Theutility model has the advantages that the operation is simple and stable, the water can be drained continuously since the structure of the upper siphon pipe is special, and the siphon effect is verygood.

Description

Less energy-consumption siphonic decant device

Technical field

The utility model relates to a kind of hydrophone of straining, and particularly relates to a kind of less energy-consumption siphonic decant device.

Background technology

The principal pollutant of municipal effluent are organism, therefore adopt biochemical process at present both at home and abroad mostly.In biochemical process, activated sludge process and biological filter two big classes are arranged, the processing efficiency of biological filter is not high, and sanitary condition is relatively poor, and China has only municipal sewage plant, several biological filters, and activated sludge process accounts for the overwhelming majority.Activated sludge process has a variety of forms, most popular three classes that mainly contain: traditional activated sludge process, oxidation ditch, SBR technology, wherein oxidation ditch and SBR technology have become the first-selected technology of domestic middle or small sewage treatment.

Straining hydrophone is the most frequently used key equipment in the sewage treatment process such as CASS method, SBR method 1CEAS method.In the waste water and municipal sewage treatment of industries such as beer, food, beverage, pharmacy, obtained widespread use based on the technology of CASS method.

Sewage work's hydrophone of straining commonly used has screw rod rotary-type water decanter, siphonic decant device, pontoon type decanting device at present.Existing siphonic decant device is because the bad siphon measure of control, and underwater portion sealing is not very tight, causes forming siphon, because design reasons can't guarantee at the uniform velocity to strain water, not have effectively to control the method for straining the water yield simultaneously.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of reasonable in design, less energy-consumption siphonic decant device that siphon effect is good are provided.

In order to address the above problem, the utility model by the following technical solutions:

A kind of less energy-consumption siphonic decant device, comprise vent valve, vapor pipe, drain header, top siphon pipe, bellows, spacing support, bottom siphon pipe and floating drum, vent valve is connected with the drain header of straining the hydrophone middle part by vapor pipe, the drain header lower end is connected with the bottom siphon pipe, the drain header upper end is connected with the top siphon pipe, the drain header bottom is provided with floating drum, connect by bellows between top siphon pipe and the floating drum, spacing support fixation is installed between top siphon pipe and the bottom siphon pipe.

Be respectively equipped with siphon jet on the described vent valve and produce switch, hold one's breath switch and minimum liquid level switch.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model has overcome and has strained the phenomenon that mill weir can not be followed the water level continuous drainage when conventional siphonic decant device is strained water, by the siphonal special tectonic in top, assurance is strained the water sucking mouth of hydrophone all the time near the water surface, when supernatant liquor is discharged, can change the function of tool continuous drainage with the variation of reaction tank water level.

2, the utility model takes into full account quantitative draining when design, by top siphon pipe and the switch of holding one's breath, siphon jet generation switch and vent valve siphon pipe is at the uniform velocity descended along water level, reaches the purpose of quantitative draining.

3. control mode of the present utility model adopts liquid level switch and vent valve to control upper and lower siphon pipe.Thereby the work that hydrophone is strained in control is easy and simple to handle, stable.

4. form bellows with anti-corrosive rubber between the upper and lower siphon pipe of the utility model, have erosion resistance and stopping property preferably, guarantee siphon effect.

Embodiment

A kind of less energy-consumption siphonic decant device, as shown in Figure 1, comprise vent valve 1, vapor pipe 2, drain header 11, top siphon pipe 3, bellows 4, spacing support 5, bottom siphon pipe 6 and floating drum 7, vent valve 1 is connected with the drain header 11 of straining the hydrophone middle part by vapor pipe 2, drain header 11 lower ends are connected with bottom siphon pipe 6, drain header 11 upper ends are connected with top siphon pipe 3, drain header 11 bottoms are provided with floating drum 7, connect by bellows 4 between top siphon pipe 3 and the floating drum 7, spacing support 5 is fixedly mounted between top siphon pipe 3 and the bottom siphon pipe 6.Be respectively equipped with siphon jet on the vent valve 1 and produce switch 8, hold one's breath switch 9 and minimum liquid level switch 10.

The utility model less energy-consumption siphonic decant device relies on gravity and siphon principle to strain water.Siphon pipe 6 bottom design in bottom have one section U type pipe that is lower than water outlet.When straining water for the first time, at first this section U type pipe is filled with water, straining in the water afterwards is lower than water outlet owing to this section U type pipe, so the water of U type pipe can not be discharged from all the time.When biochemistry pool comes water, vent valve 1 is closed, the waterborne liter in the process in the biochemistry pool, the water in the U type pipe seals, and makes air form sealing gland prevention water from vapor pipe 2 discharges drain header 11 in, until pending former water to top water-level 12.When needs were strained water, vent valve 1 was opened, and the gas of sealing in the drain header 11 is discharged from vent valve 1 by vapor pipe 2, and supernatant liquor is discharged from water port under action of gravity.When water level near drain header 11, promptly reach when holding one's breath switch activated water level 14, the switch 9 of holding one's breath can send a signal, vent valve 1 is closed, and goes out current and forms the siphon state, continues to strain water.When water level reached lowest water level 13, minimum liquid level switch 10 provided signal, and vent valve 1 is opened once again, and vapor pipe 2 air inlets destroy the siphon state, strained water and stopped, and waited for next circulation.

Claims
