Description

1 64850

The present invention relates to an arrangement according to the preamble of claim 1.

5 Such an arrangement is used to collect condensate in the intercooler, aftercooler, compressed air tank, refrigeration dryer, filters and various water separators of a compressed air compressor, to separate any oil from the condensate thus formed and to allow the system to remove this lubricating oil.

In the past, condensate collection tanks have been used from which oil can be collected separately. However, these tanks are mere separation tanks and not independent condensate treatment units. Their operation requires that each condensate collection site has a solenoid valve or similar controllable valve to control the access of condensate to the pipe leading to the tank.

20 A solenoid valve must therefore be fitted to all condensate drainage points, electrical cables must be routed, condensate pipes must be routed, and the control of solenoid valves must also be arranged separately. Since the compressed air center is in a large area, e.g. fills a large room, the installation of such a system 25 involves a considerable amount of work. Because electrical wiring and connections are available throughout the compressed air center, occupational safety is not the best. These disadvantages become more pronounced when a condensate treatment system is built on an existing compressed air center.

The object of the present invention is to eliminate the drawbacks of the previous solutions and to provide a completely new and more practical arrangement for separating and removing oil.

The invention is based on the idea that the control ΐ 2 64850 valves are assembled one below the other in a tubular rack in which the condensate flow direction is from the top outwards. Thanks to this structure, the tubular rack is made to drain automatically, so that the water does not remain standing. The arrangement according to the invention operates completely independently of the other structure of the compressed air center. In this respect, the invention differs substantially from known similar devices, which require the presence of certain components and controls from the compressed air center itself.

More specifically, the arrangement according to the invention is characterized in that the unit comprises a tubular stand arranged in the flow direction of the condensate from top to bottom, to which the control valves are attached one below the other.

The invention achieves considerable advantages, such as controllability of operation and ease of installation. In addition, an independent opening time is obtained for each valve. The opening times of the valves 20 are ensured so that several valves do not open simultaneously, which would cause an excessive condensate discharge into the tank, resulting in complete mixing of oil and water in the tank. There would also be a risk of possible damage to the equipment 25 due to the pressure release.

All this is avoided when the system is synchronized with the manufacturing technique.

Connection to an existing compressed air center is effortless, as only one Electrical Connection 30 (per plug) is required. All that is needed to connect the condensate separation points is the condensate pipes.

The invention will now be examined in more detail by means of an exemplary embodiment according to the accompanying drawing.

Figure 1 shows a side sectional view of one arrangement according to the invention.

Figure 2 shows a front view of the arrangement according to Figure 1.

The solenoid valves 7 are assembled in a flow-through top-down tubular rack 8, through which the incoming condensate is discharged through the damper 6 into the tank 10. The control center 9 is connected to the mains. The task of the control center is to give an opening command to each solenoid-10 valve 7 and to determine the duration of the opening. Each solenoid valve in turn receives an opening command at a different time, which comes manually after a preselected time. The opening time of each solenoid valve is individually selectable.

15 The control center is implemented with known electrical technology.

Each solenoid valve 7 is connected to a condensate collection site by a condensate pipe (not shown).

The device is connected to the mains, eg with a standard plug.

20 When the control center receives voltage, the operating cycle starts. After a certain time, the first solenoid valve 7 opens and releases the condensate through the rack 8 and through the damper 6 inside the tank 10. The valve remains open for a set time, e.g. 10 s. Within the set total period of 25 (e.g. 20 min), each of the valves 7 opens once and in turn releases condensate to the tank 10. The second operating cycle then starts immediately.

Once the condensate has entered the tank 10, the oil gradually separates from the emulsion 30 as the water presses heavier onto the bottom. The hydrostatic pressure lifts the water from the slit 11 into the pipe 12, which communicates with the outside air via the opening 13. The water level in the pipe rises to the height required by the hydrostatic balance between the water in the pipe and the emulsion 64850 outside the pipe. The pipe arc 1 prevents the water surface from rising too high: water flows from the branch through the opening 15, e.g. to the sewer.

The hydrostatic balance keeps the oil surface 5 at a maximum height of the sight glass 2. When the thickness of the oil layer has increased to such a level that oil is also visible from the glass 3, the oil is removed. The emulsion is drained through the tap U until the surface of the liquid has dropped to the level of the upper end of the tube 15. The liquid drained through the tap H 10 is collected for transport.

The breather 1 equalizes the pressure between the tank and the environment, so that the oil cannot spill out.

Within the scope of the invention, it is also possible to think of solutions that differ from the embodiment described above. 15 The number of solenoid valves is not fixed, but can be, for example, 3 ... 15. There may be two or more tubular talins 8 instead of one. The control center can be implemented with traditional electrical technology or completely electronically. Inspection glasses 2 and 3 20 can be replaced by a uniform glass, so that the height of the surface can be monitored continuously. the oil level can also be monitored by means of an elevation and automatic drainage can be achieved. The device can be designed to be hung on a wall, saving 25 floor space.
