Abstract
A pig system for transporting liquid or pasty substances two pig stations which are connected to one another by way of a pig line. The pig system includes a number of pigs. Accordingly, the two pig stations have a number of parking positions, to which a controllable media connection is respectively assigned. Appropriate activation of the media connections allows the effect to be achieved that only some of the pigs at a time shuttle back and forth between the two pig stations. Defective pigs or operational pigs that are being kept on standby in this case remain in corresponding parking positions of the two pig stations.
Claims3
A pig system for transporting liquid or pasty substances comprising:
- a) a first pig station, which possesses a pig channel which can receive a pig in a parking position, wherein to the parking position is assigned a controllable media connection via which pushing medium can be introduced into the pig channel such that the pig is pushed out of the pig channel;
- b) a second pig station, which possesses a second pig channel which can receive a pig in a second parking position, wherein to the second parking position is assigned a controllable media connection via which pushing medium can be introduced into the second pig channel such that the pig is pushed out of the second pig channel;
- c) a pig line which connects the pig channel to the second pig channel;
- wherein
- d) both the first and second pig stations have a plurality of parking positions in the respective first and second pig channel to which respectively an independently controllable media connection is assigned;
- and
- e) a plurality of pigs is provided in the pig system;
- wherein
- f) the media connections are controllable such that respectively only a first portion of the plurality of pigs moves between the first and second pig stations, while a second portion of the plurality of pigs remain in their parking position.
