Definitions
- the invention relates to a pigging system for transporting liquid or pasty substances, in particular paints, with a) a first pig station having a pig channel
- a second pig station which also has a
- Pig channel has, which can accommodate a pig in a parked position, wherein the parking position is assigned a controllable media port can be introduced via the sliding medium in the pig channel so that the pig is pushed out of the pig channel; c) a pig pipe, the pig channel of the one
- Pig station connects with the pig channel of the other pig station.
- Pigging systems for transporting liquid or pasty substances are widely used in industry, but especially in painting technology, where they are primarily used in supply units for application devices. There they are among others to
- Newts are subject to natural wear, so
- a pig exchange station which is located outside a pig station and contains a variety of positions in which newts, new or defective, can be stored.
- This external pig change station is connected via a line or a hose to the pig station. Normally, the pig channel in this pig station is closed by a stopper on which the only one moving in the actual pigging system
- Newt finds a stop. To replace this pig is removed by an appropriate mechanism of this plug and the leading to the pig change station tube is in connection with
- Pig can be brought out and transported to a position of the pigging station. A new, functioning pig is then introduced in the opposite direction in the pig channel of the pig station and the pig channel is closed again by the stopper. In this way you can see a lot of newts
- New cargos are needed are not entirely unimportant pointing.
- Object of the present invention is to provide a pigging system of the type mentioned, with a worn or otherwise defective
- both pig stations have a plurality of parking positions in the pig channel, each of which is assigned an independently controllable media port; e) in the pig system, a plurality of pigs is provided; where f) the media ports are controlled so that only a portion of the pigs moves between the pig stations, while the other pigs in
- a supply of pigs is not kept outside but within the actual pigging system.
- the media connections it is possible to keep only only a part of the functional pigs, preferably only one pig, active, so that this or these can oscillate between the two pig stations while fulfilling their / its transport function, while the others
- the pigging system according to the invention is also extremely inexpensive.
- the number of pigs that can be used in this way in a pigging system before opening the pigging system of course, limited.
- the pigs on a front side on a projection such that between the end faces of adjacent pigs in a pig channel a gap remains, into which a medium connection associated hole opens. In this way it can be precisely defined which pig is moved at which time and which pigs remain stationary in their parking positions.
- Figures 1 to 4 show a pigging system in different operating states.
- the figure 1 is provided with complete reference numerals, while Figures 2 to 4 for clarity, only the most important reference numerals.
- Figure 1 based on which the main components of a total provided with the reference numeral 1 pigging system will be explained.
- Pigging system 1 is used in a known manner of transporting media through a pig pipe 2, which extends between two pig stations 3, 4.
- the carriage of the Medium is done with the help of several, in the present case of three, pigs 5, 6, 7, which are housed in Figure 1 in a pig channel 8 of the left pig station 3.
- This pig station 3 thus contains three parking positions for three pigs 5, 6, 7.
- the shape of the pigs 5, 6, 7 is known as such: By a sidecut they receive in both end regions a circumferential sealing lip; at one end, in figure
- the pigs 5, 6, 7 are provided with a projection 5a, 6a and 7a.
- Drawing is the pig pipe 2, which may be either a rigid tube or a flexible hose, of course, shown only schematically, since they must have an inner diameter, the pigs 5, 6, 7 can happen.
- the pig station 3 is provided with a plurality of media ports 10, 11, 12, 13, of which in the drawing leftmost media ports 10, 11, 12 are each assigned to a parking position of the pigs 5, 6, 7.
- Shut-off valves which can release or block the inflow of pressurized media through an associated opening 14, 15, 16, 17 in the housing of the pig station 3 in the pig channel 8.
- the openings 14, 15, 16 open into a space between the parked, held by their projections 5a, 6a, 7a at a distance pigs 5, 6, 7th
- the media ports 10, 11, 12 are connected to a media supply source 18 and may be fed therefrom with push media. Which of the media Lots 10, 11, 12 respectively releases the sliding medium current and which is not, is determined by a control, not shown, in itself and according to a logic, which will be explained in more detail below.
- the fourth media port 13 which also includes a controllable valve, opens with its associated hole 17 at a location in the pig channel 8, which is located between the in FIG 1 rightmost pig 7 and the pig pipe 2.
- This media connection 13 the substance to be transported, for example paint added. He is also connected to the media supply source 18 for this purpose.
- the pigging system 1 is operated in the following way:
- the pigging system 1 has hitherto been opened in the prior art and the pig 7 has been exchanged.
- the pig 7, as shown in Figure 2 driven by the pig line 2 in the rightmost parking position in the right pig station 4, where it rests against the stop 9 '. He now remains in this position.
- the transport of the medium through the pig pipe 2 is now taken over by the middle pig 6 in FIG. 1, which, however, is now closest to the pig pipe 2 (see FIG.
- this pig 6 oscillates between the central parking position of the pig station 3 and the middle parking position of the pig station 4, whereby the connection 11 in the pig station 3 and the connection 11 'in the pig station 4 are alternately subjected to sliding medium.
- the addition of the substance to be transported in the pig station 3 can continue to take place via the media connection 13; the removal of the substance from the pig station 4 is done via the media port 11 '.
- the middle pig 6 in FIG. 1 also becomes leaky or otherwise defective, he too is driven through the pig pipe 2 into the pig station 4, namely into the middle parking position there, where it now remains permanently.
- the active function in the transport of the medium through the pig pipe 2 now assumes the in
- Figure 1 leftmost pig 5.
- the media port 10 in the left pig station 3 and the media port 12 'in the right pig station 4 of the pig 5 oscillates between the two pig stations 3 and 4 and so does its transport function . If the last pig 5 has also reached the end of its service life, it can for example, as shown in FIG. 4, still be moved into the right pig station 4. Then all unusable newts 5,
