Description
Technical field
The present invention relates to a kind of for contaminated gaseous medium, the air extractor that is used in particular for air, with leading to
Pump-line in vavuum pump and the separator for pollutant being arranged between vavuum pump and suction joint, wherein, point
There is the drain valve for emptying from utensil, the device at least partly emptying separator is connected to the drain valve.
Background technology
Air extractor being commonly known for gaseous medium, being used in particular for air.Generally, do not have in the air extractor
Necessarily involve special preparation.If however, gaseous medium is contaminated, such as mixing liquid, then separator is needed, by the separation
Device extracting liq from air so that vavuum pump below is injury-free.Especially, in wet-milling product workpiece, the sky being sucked
Gas bag contains liquid, such as emulsion, and equally also includes the solid residue in process.When the liquid and/or residue enter
Enter during in vavuum pump, vavuum pump is damaged and out of service after a short period of time.
To prevent the situation from proposing known solution, before memory is connected to pump, liquid and residue accumulation exist
In the memory.However, the memory must be cleared before maximum capacity is reached.There is wind in long-time process
Danger, i.e. the memory reaches its maximum capacity or capacity limit during processing, and must forced interruption process.To keep away
Exempt from breaking working process, concurrently build second system, the second system undertakes pumping task during the first system is cleared.
Known air extractor is distinguished in the A1 of DE10 2,009 008 204 and the A1 of US 2008/0092734, wherein, receive
Collection container is connected the downstream of separator.Air extractor tool has the advantage that, i.e. separator can be clear in process
Sky, without interrupting pumping process.In addition it is also possible to give up second system completely.Separator is flushed into trapping memory,
That is, the first drain valve being located between separator and trapping memory is opened.If the first drain valve is closed again, can open
The second drain valve at trapping memory, and trapping memory can be flushed into outside or another container.
The content of the invention
It is an object of the present invention to provide a kind of air extractor, the air extractor has more relative to prior art
Advantage.
According to the present invention, the purpose is accomplished in the following manner in the air extractor of the above-mentioned type, i.e. separated in connection
Sensor is provided with device and the pipeline of drain valve.
If being determined by means of liquid level sensor that the liquid assembled in the separator must be discharged in known air extractor,
The drain valve being then connected on separator is opened, and thus separator is connected with collection vessel.Because the collection vessel first by
Empty, it is vented and under normal pressure.Collection vessel is caused in separator and collection vessel with the connection of separator
Pressure balance, the thus vacuum decay in the separator for being used as vaccum memory.However, because separator is relatively full
, the strong vortice of the liquid for promoting to collect in the separator from collection vessel leaked-in air, its air inlet pipe for being likely to be at pump
In road.
In the present invention, at least partly emptying the device e.g. collection vessel of separator.It is equally emptying it
It is connected with separator afterwards.But this has been carried out when in the sensor record set in connecting pipeline of the separator with drain valve
Aggregation of the liquid in the pipeline.However, this amount is small relative to the volume of separator so that will not for miscellaneous part
Occur dangerous.Additionally, when drain valve is opened, liquid is after pressure equalization in total unhinderedly inflow collection vessel.Separately
One advantage is to notice that separator is always basic empty.
Set in an expansion scheme of the invention, the sensor set in pipeline of the connection separator with drain valve
It is liquid level sensor.It is contemplated that other sensors, such as ohmmeter, capacitance sensor.
One alternative implementation method setting, the device at least partly emptying separator is pump.The suction of the pump it is big
Small to cause that it is more than the vacuum in separator, the liquid thus assembled wherein can be extracted, without partly to separator
Ventilation.
In order to avoid the possibility being included in the air being sucked causes the residual processing thing for damaging to enter in air extractor
Enter system, before filter is arranged on separator, especially in pump-line.The filter is preferably solid or solid material
Filter.Metal fillings or other solid materials are separated from the air being sucked in this way, and liquid passed through
Filter.
Be accomplished in the following manner to air extractor, especially to the extra control of separator, i.e. separator has visual
Liquid level display.Operator can quickly be checked by means of the display, air extractor whether normal work.
Set in an expansion scheme of the invention, then collection vessel is provided with ventilation shaft.By the ventilation shaft
The pressure balance with environment can be being produced before collection vessel is cleared in collection vessel.
The sensitive response of drain valve is accomplished in the following manner according to the present invention, i.e. it is built into squeezing valve.Additionally,
Squeezing valve is durable and anti-erosion and corrosive medium.
Set in a preferred embodiment, vacuum circuit breaker is provided with pump-line.Advantageously, vacuum circuit breaker
It is arranged in the bypass duct relative to pump-line.Be can ensure that by the vacuum circuit breaker, the vacuum in pump-line, example
Such as by opening drain valve without dropping under lower threshold values.When the threshold values is reached, drain valve is for example closed again, until
Form desired vacuum again in pump-line or in the separator.
Brief description of the drawings
Other advantages of the invention, feature and details are given in dependent claims and following description, wherein, ginseng
Examine accompanying drawing and describe especially preferred embodiment of the invention in detail.Here, being shown in the drawings and in specification and right
It is required that in the feature that refers to respectively itself or for the present invention be in any combination important.
The accompanying drawing shows a particularly preferred embodiment of the invention.
Specific embodiment
In air extractor of the invention 10, vavuum pump 12 is connected on separator 14 by pump-line 8 so that
Air can be sucked out by the separator 14 and filter 16 from the clamping device 18 for workpiece 20.Two sensors
22 and 24 are located on separator 14, wherein, the two sensors are configured to liquid level sensor, be can determine that by the liquid level sensor
Liquid level in separator 14, and this outer sensor 22 works as visual liquid level display.Two quilts of sensor 22 and 24
It is connected on control device 26.
Separator 14 is connected by pipeline 28 with least partly emptying the device 30 of separator 14, wherein, the device
30 are for example built into collection vessel 32.The pipeline 28 can be opened by the drain valve 34 for being built into squeezing valve.In pipeline 28
There is sensor 36 to be located between the drain valve 34 and separator 14, liquid level equally can determine that by the sensor.Not only sensor
36th, drain valve 34 and control device 26 is connected on second control device 38, by the second control device controllable second
Drain valve 40.If liquid is positioned horizontally between sensor 24 and 36, drain valve 34 is opened, and liquid flows from separator 14
Go out to enter into collection vessel 32.As long as liquid level reaches sensor 36, then drain valve 34 is closed.It is achieved in essential advantage, i.e.
Liquid is always kept in pipeline 28, and it prevents the vacuum in separator 14 from collapsing.
Before liquid is discharged in tank 44, in order to empty collection vessel 32, the collection vessel can be by drain valve 40
It is connected with the ventilation shaft 42 led in environment.
Bypass duct 46 is also located in pump-line, and vacuum circuit breaker 48 is provided with bypass duct.
