Definitions

• This invention relates to an apparatus in a pipeline milking plant comprising an air separator connected to a milk pipeline at least at one place so that milk streams into the air separator, where the air mixed into the milk is separated and streams through an inlet to a sanitary trap which is fastened on the air separator and which is intended to separate fluid particles from the entering air, the sanitary trap being connected to a line in which vacuum prevails.
• an air separator for separating the air mixed into the milk.
• the air separator comprises at least one inlet, preferably on its side wall for milk mixed with air and an outlet, preferably at its bottom for the milk separated from air.
• a vacuum connection in the air separator preferably at its upper part, whereby the milk mixed with air can be sucked through the pipelines to the air separator.
• the vacuum connection in the air separator is in connection with the vacuum source of the plant which source, as a rule, comprises a vacuum pump.
• the milk mixed with air is sucked into the air separator where the milk is separated from air and streams out of the air separator at its bottom.
• the air having been separated from the milk is sucked out of the air separator via the vacuum connection.
• Fig. 1 shows a first embodiment
• Fig. 2 shows a modification of the embodiment according to Fig. 1
• Fig. 3 shows a third embodiment.
• Fig. 1 there is shown the upper part of an air separator 10, on top of which is fastened a sanitary trap 11. There is an open connection between the latter and the air separator.
• the sanitary trap 11 comprises a receptacle 12 with walls forming a tube 13 about in the centre of the receptacle.
• This tube encloses the opening between the air separator 10 and the sani tary trap 11 and has a cross section area being essentially less than that of the sanitary trap.
• the tube 13 functions as a level tube for that fluid that is separated in the sanitary trap and prevents the separated fluid to stream back to the air separator.
• the sanitary trap comprises a vacuum connection 14 that can be shut off by means of a valve not shown.
• a guide 16 for a float 17 In the receptacle on one side of the tube 13 there is arranged a guide 16 for a float 17. This float that preferably has the form of a ball 17 moves up and down in dependence on the fluid level In the receptacle 12 and In its uppermost position can shut off the vacuum connection.
• the upper part of the tube 13 debouches on a level 21 that is considerably higher than the level 15 on which the bottom part of the receptacle 12 is positioned. That means that the risk that condensate accumulated in the receptacle 12 shall stream down into the air separator 10 is eliminated.
• the level 21 is positioned above that level 22 on which the vacuum connection 14 debouches in the container 12.
• the tube 13 is placed beside the vacuum connection 14. That means that the opening of the inlet to the sanitary trap is positioned on a higher level than and is laterally displaced In relation to the opening of the line where vacuum prevails.
• the tube 13 and the vacuum connection 14 have been made in one piece with the receptacle. This is, of course, not necessary but the tube and the vacuum connection may consist of separate details which are fastened onto the receptacle. According to another alternative the tube is made in one piece with the air separator, the sanitary trap having such a design that it can be placed outside the tube and thus enclose it.
• fluid particles are separated in the sanitary trap 11 from the air entering via the tube 13. These fluid particles are collected on the bottom of the sanitary trap, whereafter the fluid level In this one successively increases. Due to that fact the float begins to move upwards until it reaches its uppermost position. In this position the float closes the opening of the vacuum connection 14, whereby the vacuum in the receptacle 12 is reduced. This in its turn has the consequence that the shut off-valve of the conduit 18 is opened, whereby the fluid in the receptacle 12 Is drained off.
• the cleaning fluid is injected into the sanitary trap 11 via a not shewn cleaning fluid sprinkler, a part of the cleaning fluid streaming down into the air separator on the Inside of the tube 13. The rest of the cleaning fluid streams along the walls on the inside of the receptacle 12 down to its bottom where it is accumulated.
• connection 20 to which a not shown tube is connected, the other connection is either the air separator 10 or a line going to that one.
• the tube In the tube there is a valve that Is closed during milking and open during cleaning.
• the connection 20 makes a feed back of cleaning fluid to the pipeline milking system possible.
• cleaning fluid is collected on the bottom of the receptacle 12.
• the cleaning fluid streams out of the receptacle 12 via this connection and into the air separator 10 where it is mixed with the rest of the cleaning fluid for further transport through the system.
• connection 20 is positioned on a higher level than the connection 18.
• the advantage with this fact is that cleaning fluid is left on the bottom of the receptacle 12. This cleaning fluid is drained off when the shut-off valve in the conduit to the connection 18 is opened, whereby also this conduit is cleaned.
• FIG. 2 there is shown a modification of the apparatus according to Fig. 1.
• the apparatus according to Fig. 2 has no connection 20 and is instead provided with a closable opening 23 in the wall of the tube 13.
• the opening 23 is suitably closed by means of a bar 24 going through the wall of the receptacle 12, whereby the bar 24 can be operated outside the receptacle 12.
• the opening 23 is closed during the milking procedure and is open during the cleaning procedure.
• the operation of the bar 24 can be made automatically via signals from for instance the cleaning apparatus.
• the cleaning of the apparatus according to Fig. 2 functions essentially In the same way as in the apparatus according toFig. 1.
• cleaning fluid is brought Into the receptacle 12 via the connection 19.
• the level of the cleaning fluid that. is accumulated on the bottom of the receptacle 12 rises until it reaches the opening 23, whereafter the cleaning fluid streams down through the tube 13 to the air separator 10.
• a further embodiment of the invention differs from the first one regarding the design of the sanitary trap.
• the sanitary trap comprises a receptacle 30 which is fastened on the top of the air separator 31.
• a vacuum connection 32 which is placed at the centre line of the receptacle.
• a tube 33 Into the receptacle 30 at one side of its centre line there is made a tube 33, one end of which constitutes the opening between the sanitary trap and the air separator and the other end of which debouches in the upper part of the receptacle 30 and constitutes the inlet to the sanitary trap.
• the inlet opening to the sanitary trap is laterally displaced in relation to the opening of conduit where vacuum prevails.
• the upper part of the tube has a sloping roof 34 which leads the air mixed with fluid particles towards the side wall of the receptacle.
• the air Is thrown downwards before it passes out through the vacuum connection 32 as is shown by arrows In the figure. Due to that fact a good separation of fluid particles from the mixture of air and fluid particles entering the receptacle 30 is made, which fluid particles are collected on the bottom of the receptacle 30.
• the upper part of the tube 33 debouches on a level 37 positioned considerably higher than the level 38 of the bottom part of the receptacle 30. Due to that fact the risk is eliminated that the fluid that is collected In the lower part of the sanitary trap shall stream down into Furthermore, in the receptacle 30 there is a ball 35 functioning as a float, which ball moves upwards in the receptacle in dependence on the fluid level in the same. In the bottom of the receptacle 30 there is an automatic shut-off valve 36 which functions in that way that when vacuum prevails in the receptacle, the valve is closed, and when the vacuum in the receptacle is reduced, the valve is opened.
• valve 36 can, of course, be directly governed by the fluid level in the sanitary trap so that when the fluid in this one has reached a certain level the valve 36 is opened and the sanitary trap 30 is drained off. Due to the fact that the tube 33 is laterally displaced in relation to the vacuum connection 32 and that there is a sloping roof 34 the risk is eliminated that fluid particles shall fall down into the tube and then down to the air separator.
