Abstract
The invention relates to a suction device for contaminated gaseous media, particularly for air, with a suction line leading into a vacuum pump and a separator for the contaminants connected between the vacuum pump and the suction connection. The separator has an outlet valve for emptying, to which a device for at least partially emptying the separator is connected, wherein a sensor is provided in the line connecting the separator with said outlet valve.
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, there is the pump-line led in vavuum pump and the separator for pollutant be arranged between vavuum pump and suction joint, wherein, separator has the drain valve for emptying, and the device for emptying separator is at least partly connected to this drain valve.
Background technology
Usually air extractor that become known for gaseous medium, that be used in particular for air.Usually, do not have to relate to special preparation in this air extractor.But, if gaseous medium is contaminated, such as, mix liquid, then need separator, by this separator extracting liq from air, make vavuum pump below injury-free.Especially, when wet processing work, the air rubber capsule be sucked such as, containing liquid, emulsion, and equally also comprises the solid residue in process.When this liquid and/or residue enter into vavuum pump, vavuum pump damaged and out of service after a short period of time.
For preventing this situation from proposing known solution, before memory is connected to pump, liquid and residue accumulation are in this memory.But this memory must be cleared before reaching heap(ed) capacity.In long-time process, there is risk, that is, this memory reaches its heap(ed) capacity or capacity restriction between processing period, and must forced interruption process.For avoidance breakout process, build second system concurrently, this second system bears the task of bleeding during the first system is cleared.
The known air extractor of difference in DE102009008204A1 and US2008/0092734A1, wherein, collection container is connected the downstream of separator.This air extractor has following advantage, that is, separator can be cleared in process, and need not interrupt pumping process.In addition, also second system can be given up completely.Separator is flushed in trapping memory, that is, open the first drain valve between separator and trapping memory.If the first drain valve is closed again, then can open second drain valve at trapping memory place, and trapping memory can be flushed in outside or another container.
Summary of the invention
The object of the invention is to, provide a kind of air extractor, this air extractor has more advantage relative to prior art.
According to the present invention, this object is realized by following manner in the air extractor of the above-mentioned type, that is, in the pipeline connecting separator and drain valve, be provided with sensor.
If determine to discharge the liquid assembled in the separator by means of liquid level sensor in known air extractor, then the drain valve be connected on separator is opened, and separator is connected with collection container thus.Because first this collection container is cleared, it is ventilated and under being in normal pressure.The connection of collection container and separator makes the pressure balance in separator and collection container, and the vacuum thus in the separator being used as vaccum memory declines.But because separator is relatively full, impel the strong eddy current of the liquid collected in the separator from collection container leaked-in air, it may be in the admission line of pump.
In the present invention, be such as collection container for emptying the device of separator at least partly.It is connected with separator equally after emptying.But this has realized liquid in this ducted gathering when the sensor record arranged in the pipeline connecting separator and drain valve.But this amount is little relative to the volume of separator, make danger be there will not be for miscellaneous part.In addition, when drain valve is opened, liquid is total after pressure equalization unhinderedly to be flowed in collection container.Another advantage is, notices that separator is always basic empty.
Set in an expansion scheme of the present invention, the sensor arranged in the pipeline connecting separator and drain valve is liquid level sensor.Other sensors can be imagined, as ohmmeter, capacitance sensor etc.
An alternative embodiment setting is pump for emptying the device of separator at least partly.The size of the suction of this pump makes it be greater than vacuum in separator, and the liquid assembled wherein thus can be drawn out of, and need not partly ventilate to separator.
In order to avoid the residual processing thing of damage that may cause in air extractor be included in the air that is sucked enters system, before filter is arranged on separator, especially in pump-line.This filter is preferably solid or solid material filter.Metal fillings or other solid materials are separated from the air be sucked in this way, and liquid passes through filter.
By following manner realize to air extractor, especially to the extra control of separator, that is, separator has visual liquid level display.Operator can check fast by means of this display, and whether air extractor normally works.
Set in an expansion scheme of the present invention, then collection container is provided with ventilation shaft.Before collection container is cleared, the pressure balance with environment can be produced in collection container by this ventilation shaft.
Realized the sensitivity response of drain valve by following manner according to the present invention, that is, it is built into squeezing valve.In addition, squeezing valve is durable and anti-erosion and corrosive medium.
Set in a preferred embodiment, in pump-line, be provided with vacuum circuit breaker.Advantageously, vacuum circuit breaker is arranged in the bypass duct relative to pump-line.Can be guaranteed by this vacuum circuit breaker, the vacuum in pump-line, such as, do not drop under lower threshold values by opening drain valve.When reaching this threshold values, drain valve is such as closed again, until at pump-line or again form desired vacuum in the separator.
Accompanying drawing explanation
Dependent claims and below description in provide other advantages of the present invention, characteristic sum details, wherein, be described in detail with reference to the attached drawings particularly preferred embodiment of the present invention.At this, the illustrated in the accompanying drawings and feature mentioned in the specification and in the claims respectively self or be important to combine arbitrarily for the present invention.
This accompanying drawing illustrates a particularly preferred embodiment of the present invention.
Detailed description of the invention
In air extractor 10 according to the present invention, vavuum pump 12 is connected on separator 14 by pump-line 8, makes air be sucked out from the clamping device 18 for workpiece 20 by this separator 14 and filter 16.Two sensors 22 and 24 are positioned on separator 14, and wherein, these two sensors are configured to liquid level sensor, can determine the liquid level in separator 14 by this liquid level sensor, and this outer sensor 22 works as visual liquid level display.Two sensors 22 and 24 are connected on control device 26.
Separator 14 is connected with the device 30 for emptying separator 14 at least partly by pipeline 28, and wherein, this device 30 is such as built into collection container 32.This pipeline 28 can be opened by the drain valve 34 being built into squeezing valve.In pipeline 28, there is sensor 36 between this drain valve 34 and separator 14, can liquid level be determined equally by this sensor.Not only sensor 36, drain valve 34 but also control device 26 are connected on second control device 38, can control second row put valve 40 by this second control device.If being positioned horizontally between sensor 24 and 36 of liquid, then drain valve 34 is opened, and liquid enters into collection container 32 from separator 14 outflow.As long as liquid level reaches sensor 36, then drain valve 34 closes.Realize essential advantage thus, that is, liquid is always retained 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 container 32, this collection container is connected with the ventilation shaft 42 led in environment by drain valve 40.
Bypass duct 46 is also arranged in pump-line, is provided with vacuum circuit breaker 48 in bypass duct.
