Abstract
The invention relates to a device for processing, especially for filtering and removing, fluids and fluid remnants in a low-pressure chamber (1). Said device comprises a vacuum pump (30) and a separator (16), whereby the low-pressure chamber is connected to the separator via a first line (10), and the low-pressure chamber is connected to the vacuum pump via a second line (20) so that the low-pressure chamber can be evacuated while bypassing the separator. The invention also relates to a low-pressure chamber for processing fluids which is equipped with a heating plate with holes for heating areas of the interior space of the low-pressure chamber.
Claims30
Apparatus for treating liquids in a negtive pressure chamber, having a vacuum pump and a separator, the negtive pressure chamber being connected to the separator by a first line and a first closure device being arranged between the negtive pressure chamber and separator, while the negtive pressure chamber is connected to the vacuum pump via a second line, so that the negtive pressure chamber can be evacuated while avoiding the separator.
Apparatus according to one of the preceding claims, characterised in that a second closure device is provided in the second line between the negtive pressure chamber and vacuum pump.
Apparatus according to one of the preceding claims, characterised in that the vacuum pump and the additional vacuum pump are replaced by one vacuum pump.
Apparatus according to one of the preceding claims, characterised in that the first and second closure device are replaced by a first 3/2-way valve.
Apparatus according to one of the preceding claims, characterised in that the additional first and additional second closure device are replaced by an additional 3/2-way valve.
Apparatus according to one of the preceding claims, characterised in that the apparatus is an apparatus for filtering liquids.
Apparatus according to one of the preceding claims, characterised in that the apparatus is an apparatus for eliminating liquids in a negtive pressure chamber.
Apparatus according to one of the preceding claims, characterised in that a ventilation valve is provided on the negtive pressure chamber.
Apparatus according to one of the preceding claims, characterised in that a throttle valve is provided between the ventilation valve and the negtive pressure chamber.
Apparatus according to one of the preceding claims, characterised in that the apparatus comprises an electronic unit for controlling closure devices, 3/2-way valves, ventilation valve, throttle valve and/or vacuum pumps.
Negtive pressure chamber for treating liquids, particularly for use with an apparatus according to one of the preceding claims, wherein the negtive pressure chamber comprises a hotplate, preferably with holes, for heating areas of the interior of the negtive pressure chamber.
Process for eliminating liquid residues in an negtive pressure chamber comprising the following steps:
- a) the negtive pressure chamber is sealed off to be airtight;
- b) the negtive pressure chamber is connected to a vacuum pump and the separator is separated from the negtive pressure chamber and vacuum pump;
- c) the vacuum pump is switched on and the negtive pressure chamber is pumped out.
