Abstract
The utility model provides a highly automatic structure which is used for collecting liquid with a large area and small liquid level surface disturbance and controlling liquid level. The pressure air liquid level control weir is applicable for controlling and collecting chemical liquid with small consistency. A PLC processes data collected by a pressure testing instrument and controls opening and closing of an inlet valve and an outlet valve, and further controls air pressure in an air cover, thereby realizing elevation of liquid level and collection of liquid. The pressure air liquid level control weir solves the problem that liquid collection area is large, liquid output is unstable. The pressure air liquid level control weir is simple and effective in structure, durable, low in cost and highly automatic, and can realize collection and discharge of liquid with a large area and small disturbance.
Description
Technical field
The utility model relates to a kind of fluid level controller, and particularly large tracts of land is collected the environmental protection equipment of liquid, belongs to field of environment protection.
Background technology
At field of environment protection, often need large tracts of land to collect liquid, require for a short time to the disturbance of liquid level face, and realize automatic control of liquid level to the full extent.
For many years; In order to realize the stable collection of liquid; Realize the autostable control of liquid level, people have carried out the more planting the liquid collection structure of thinking, the research and the test of equipment, develop various liquid collection structure, equipment; Wherein main is the mode through moving structure equipment, realizes the collection and the liquid level control of liquid.But owing to mobile unit is also unstable in lifting process, structure often breaks down, and the control difficulty is high, and production cost is higher, and prior art can't realize the efficient stable application under the low production cost condition.
How to develop a kind of simple in structure effectively, with low cost and supermatic fluid collection systems is the major issue that needs to be resolved hurrily.
Summary of the invention
The purpose of the utility model provides and a kind ofly can be used for that large tracts of land is collected liquid, the disturbance of liquid level face is little, the increasingly automated structure of liquid level control.
The purpose of the utility model realizes through following technical scheme:
The utility model is a kind of pressure air fluid level controller, mainly comprises gas hood, fluid weir and fluid feeder, it is characterized in that; Airhood provides air at air feed equipment, and air capacity increases in the gas hood, and pressure increases; Liquid between airhood and fluid weir is pushed, is isolated in the gas hood outside, but liquid level is reduced under the inner liquid level of gas hood of fluid weir fluid in the gas hood, logic control equipment obtains pressure data through pressure controller; Air feed equipment shut down when pressure was higher than hydraulic coupling, and gas admittance valve cuts out, and the fluid weir is fluid not; When needing fluid, open the vent valve release, it is negative value that fluid level controller obtains pressure data; And when being lower than certain negative value, the voltage supply of air feed equipment emergency starting air feed.
Described air-pressure controlling weir is characterized in that, described logic control equipment connects pressure controller, obtains the pressure between gas hood and fluid weir, sends other equipment of control signal control after pressure data focuses on.
Described gas hood is done preservative treatment, and gas block panel and top board around gas hood mainly comprises are fixed in liquid upper, and part is exposed liquid level;
Described fluid weir is positioned at gas hood inside, and fluid weir and gas hood are to the weir plate around should having and the base plate on fluid weir.The distance of weir plate and gas hood is certain, weir plate top indentation, and the weir plate level is put, and liquid is kept apart through base plate and former mixing material through the stable weir plate inside that flows into of weir plate;
The top of described fluid feeder and fluid weir connect into catchment tray, and flowing into fluid weir liquid can discharge from the fluid collection system through gravity flow.
Described air system is made up of voltage supply equipment and corresponding pipeline valve; Voltage supply equipment provides pressure control airhood internal pressure; Under the airhood internal pressure reduction situation, liquid level raises in the airhood, and liquid level reduces to keep and the atmospheric pressure equilibrium of forces under the situation that pressure improves.
Also comprise control system, programmable controller (PLC) deals with the back and is communicated with the inlet, outlet valve through collect the data of collection from pressure test, the switching of by-pass valve control, control air cover internal gas pressure size.
The utlity model has following advantage and positive effect:
Pressure air control weir by above-mentioned the utility model provides can find out that the utility model is discharged the collection of liquid, has solved big, the fluid problem of unstable of fluid collection area, has characteristics such as simple in structure effective, with low cost and increasingly automated.
The utility model is through laboratory proofing, and pressure air control weir is applicable to: the chemical industry fluid that viscosity is little.When the collection of such fluid of control, fluid effluents stable, and equipment is durable in use.Large tracts of land, the little liquid collection discharge of disturbance can effectively be realized in pressure air control weir.
Description of drawings
Accompanying drawing is the manuscript on the utility model pressure air weir.
The numbering of each several part explanation in the synoptic diagram:
Gas hood (1), fluid weir (2), fluid feeder (3), air feed equipment (4), gas admittance valve (5), vent valve (6), logic control equipment (7), pressure controller (8) discharging tube (9), tapping valve (10).
Embodiment
In the drawings; Fluid weir (2) places gas hood (1) inside with fluid feeder (3); Gas hood (1) rises in the situation downforce that gas admittance valve (5) is opened or vent valve (6) unlatching is littler than gas admittance valve (5), and pressure controller (8) is collected pressure information simultaneously, and pressure information is sent to logic control equipment (7); Pressure value reaches and stops air feed when stopping hydraulic coupling, and this has just realized the maintenance of liquid level; Open when needing discharge opeing vent valve (6) or with the ratio gas admittance valve (5) that vent valve (6) is opened open big; Pressure controller (8) is collected pressure information; Pressure information is sent to logic control equipment (7), closes vent valve (6) and gas admittance valve (5) when pressure value reaches hydraulic coupling, the too small liquid of pressure possibly get into vent valve (6); Logic control equipment (7) emergency opening gas admittance valve (5) keeps certain pressure in the gas hood; Liquid flows into fluid feeder (3) from fluid weir (2) when normally going out hydraulic coupling, imports discharging tube (9), opens tapping valve (10) back discharged liquid.Valve adopts electrically operated valve.
Claims (2)
1. a pressure air fluid level controller mainly comprises gas hood (1), fluid weir (2) and fluid feeder (3), it is characterized in that; Airhood (1) provides air at air feed equipment (4), and air capacity increases in the gas hood, and pressure increases; Liquid between airhood (1) and fluid weir (2) is pushed, is isolated in the gas hood outside, and the interior liquid level of gas hood is reduced to fluid weir (2) but under the inner liquid level of the gas hood of fluid, logic control equipment (7) obtains pressure data through pressure controller (8); Air feed equipment when pressure is higher than hydraulic coupling (4) shuts down, and gas admittance valve (5) cuts out, and fluid weir (2) are fluid not; When needing fluid, open vent valve (6) release, it is negative value that fluid level controller (8) obtains pressure data; And when being lower than certain negative value, the voltage supply of air feed equipment (4) emergency starting air feed.
2. air-pressure controlling according to claim 1 weir; It is characterized in that described logic control equipment (7) connects pressure controller (8); Obtain the pressure between gas hood (1) and fluid weir (2), send other equipment of control signal control after pressure data focuses on.
