Abstract
Apparatus 20 for delivering a volume of rinse water into a main milk pipeline 2 comprises annular inner and outer compartments 37 and 38, which communicate through an opening 40, forming a holding chamber 28 for the water. The water is delivered to the main milk pipeline 2 through the main outlet 32. The holding compartment 28 is charged by the wash line 15 through a main inlet 44. A solenoid controlled diaphragm valve 47 selectively opens a secondary inlet 45 to the outer compartment 38 of the holding chamber 28, so that when a vacuum is applied to the main milk pipeline 2 and the valve 47 is opened to atmosphere the wash water is urged from the holding chamber 28 to flow with full flow characteristics as a plug of wash water through the main milk pipeline 2.
Description
Apparatus for holding a volume of liquid for delivering into a pipeline, and a method for delivering a volume of liquid into a pipeline
The present invention relates to apparatus for holding a volume of liquid for delivery into a pipeline so that the liquid when delivered into the pipeline flows with full flow characteristics. In particular, the apparatus according to the invention is for holding a volume of water with or without a detergent and/or a disinfectant for cleansing a pipeline of a milking apparatus. The invention also relates to the milking apparatus containing the holding apparatus, and to a method for delivering a volume of liquid into a pipeline, for example, for delivering a volume of water, with or without a detergent and/or disinfectant for cleansing a pipeline of the milking apparatus.
Milking apparatus, in general, comprises a relatively long main milk pipeline which typically, is located overhead in a milking parlour. A plurality of milking clusters for attaching to the cow's teats for milking are Teed into the main milk pipeline. The main milk pipeline terminates in a receiver which is held under vacuum by a vacuum system for drawing the milk through the main milk pipeline, and in turn, from the cow's
S 7777 4 teats. A milk pump delivers milk from the receiver to a holding tank. The vacuum system is also applied through a pulsator to sleeves in the clusters for causing the sleeves to pulsate for urging milk from the cow's teats.
A separate wash pipeline for carrying washing water which may or may not contain a detergent and/or a disinfectant, and rinse water also runs overhead in the milking parlour adjacent the main pipeline. A plurality of jetters, one for each milking cluster are Teed off from the wash line for connecting to the corresponding cluster for facilitating washing the milklines, receiver jar, and pump through which milk passes after milking has been completed. Such milking apparatus and wash lines will be well known to those skilled in the art.
It is, however, important that the milk lines be thoroughly cleaned after each milking session to avoid the growth of bacteria in the milk lines. In milk lines of relatively small diameter, thorough cleansing of the milk lines is achieved using conventional systems. Because of the relatively small diameter of the pipelines, it is possible to have the cleansing liquid, typically, water with a detergent and rinsing water to flow with full flow characteristics through all the milk lines, thereby adequately cleansing the milk lines. However, in relatively large installations, the overhead main milk pipeline, can be of relatively large diameter, and in general, known washing techniques are unsatisfactory. It is, in general, impossible to get the wash water and rinse water to flow with full flow characteristics throughout the entire main milk pipeline.
There is therefore a need for an apparatus for overcoming this problem, and also for a method for overcoming the problem, both in milk apparatus and other apparatus.
The present invention is directed towards providing such a method and apparatus.
According to the invention there is provided apparatus for holding a volume of liquid for delivery into a pipeline to flow through the pipeline with full flow characteristics, the apparatus comprising an enclosed holding chamber for holding the volume of liquid for delivery into the pipeline, the holding chamber having a communicating outlet for communicating with the r pipeline for delivering the volume of liquid from the holding chamber into the pipeline, a main inlet for charging the holding chamber with the liquid, and a secondary inlet for communicating the holding chamber with a medium source for applying a pressure differential across the volume of liquid in the holding chamber between the secondary inlet and the communicating outlet when the communicating outlet is communicating with the pipeline for urging the volume of liquid from the holding chamber to flow through the pipeline with full flow characteristics, the secondary inlet being arranged relative to the communicating outlet so that the volume of liquid in the holding chamber acts as a seal between the secondary inlet and the communicating outlet, and the communicating outlet is located for retaining the volume of liquid in the holding chamber when no pressure differential exists.
Preferably, a valve means is provided for selectively closing the secondary inlet during charging of the holding chamber, and for opening the secondary outlet for facilitating delivery of the volume of liquid from the holding chamber through the communicating outlet for in turn facilitating flow of the volume of liquid through the pipeline with full flow characteristics.
In one aspect of the invention the apparatus comprises a housing defining an enclosed hollow interior region within which the holding chamber and a discharge chamber are formed, the holding chamber communicating with the discharge chamber through the communicating outlet, and a main outlet being provided from the discharge chamber for connecting to the pipeline.
In another embodiment of the invention the communicating outlet is formed by a weir.
In another embodiment of the invention a bulkhead extends downwardly into the holding chamber for dividing the holding chamber into two compartments for isolating the secondary inlet from the communicating outlet, the two compartments communicating with each other through a communicating opening located at the lower end of the bulkhead so that the two compartments, effectively form a U-shaped liquid seal between the secondary inlet and the communicating outlet.
In another embodiment of the invention the communicating opening is formed between a lower edge of the bulkhead and a base of the holding chamber.
In another embodiment of the invention the holding chamber is an annular chamber and extends around the discharge chamber. Preferably, the main outlet is located in a base of the discharge chamber.
Ideally, the weir defines with a common top wall of the holding chamber and the discharge chamber an annular communicating outlet.
Advantageously, the bulkhead is provided by a cylindrical wall extending downwardly from the common top wall, and forms the two compartments, namely, an inner annular compartment and an outer annular compartment. Preferably, the secondary inlet communicates with the outer compartment.
Advantageously, the main inlet is located in the base of the holding chamber, and preferably, is located substantially beneath the inner compartment.
In one embodiment of the invention the apparatus is adapted for connecting to a milk pipeline, and in use, the main outlet is connected to the main milk pipeline, preferably, at an upstream end of the main milk pipeline onto which the clusters are Teed. The upstream end of the main milk pipeline being remote from the receiver.
In one embodiment of the invention the main inlet is connected to the wash line, for receiving washing and rinsing water therefrom.
In another embodiment of the invention the secondary inlet communicates with atmosphere for communicating the holding compartment with atmosphere, and preferably, the valve means is vacuum operated, and is connected to the vacuum system of the milking apparatus
I for operation thereof for selectively opening and closing the secondary inlet, and preferably, is » connected to the non-pulsating part of the vacuum system. Ideally, a controller is provided for controlling the supply of vacuum to the valve for operation of the valve for selectively opening and closing the secondary inlet.
Additionally, the invention provides a pipeline and the apparatus according to the invention for holding a volume of liquid for delivery into the pipeline, the apparatus being connected to the pipeline.
Further, the invention provides milking apparatus comprising the apparatus according to the invention for holding a volume of liquid for delivery into a main milk pipeline of the milking apparatus, the apparatus being connected to the main milk pipeline at an upstream end thereof remote from a receiver to which the main milk pipeline is connected at the other end thereof.
1.
The invention also provides a method for delivering a volume of liquid into a pipeline to flow will full flow characteristics, the method comprising the steps of storing the volume of liquid in a holding chamber having a communicating outlet communicating with the pipeline, and a main inlet for charging the holding chamber with the liquid, and a secondary inlet for applying a pressure differential across the volume of liquid between the secondary inlet and the communicating outlet, the method comprising the furthest step of opening the secondary inlet for applying the pressure differential across the volume of liquid for urging the volume of liquid from the holding chamber into the pipeline to flow through the pipeline with full flow characteristics.
The invention will be more clearly understood from the following description of an embodiment thereof which is given by way of example only with reference to the accompanying drawings in which:
Fig. 1 is apparatus a schematic diagram of a milking according to the invention,
Fig. 2 is an cross-sectional elevational view of apparatus also according to the invention for use in the milking apparatus of Fig. 1, and
Fig. 3 is an exploded perspective view of the apparatus of Fig. 2.
Referring to the drawings there is illustrated milking apparatus according to the invention which is indicated generally by the reference numeral 1. The milking apparatus 1 comprises a main milk pipeline 2, which typically, is located overhead in a milking parlour.
The main milk pipeline runs from an upstream end 3 to a downstream end 4 where it terminates in a receiver 5 for receiving milk. A plurality of milking clusters 7, only one of which is illustrated in Fig. 1 are Teed into the main milk pipeline 2 for delivering milk from the cow's teats into the main milk pipeline 2. A vacuum system indicated generally by the reference numeral 10 applies a continuous vacuum to the receiver 5 through a vacuum line 11 for drawing milk from the clusters 7 through the main milk pipeline 2 into the receiver 5. A pump 12 pumps milk from the receiver 5 into a holding tank (not shown). The vacuum system 10 through a pulsator 14 applies a pulsating vacuum to sleeves (not shown) in the clusters 7 for urging milk from the teats of an animal being milked. A wash line 15, which is also located overhead in the milking parlour, in general, runs substantially parallel adjacent the main milk pipeline 2. The wash line 15 terminates in a trough 16 from which washing water which typically, comprises a detergent and/or a disinfectant and rinse water is drawn by the wash line 15 for cleansing the milking apparatus. A plurality of jetters 18 are Teed from the wash line 15 for connection to the milking clusters 7 so that the wash water and rinse water can be drawn from the trough 16, and in turn through the clusters 7, the main pipeline 2, and into the receiver 5 under the vacuum applied by the vacuum line 11. The wash and rinse water may then be pumped by the pump 12 and returned to the trough 16 for further circulation through the milking apparatus.
So far to here, the milking apparatus 1 is a conventional milking apparatus and is of the type which will be well known to those skilled in the art.
Apparatus also according to the invention which is indicated generally by the reference numeral 20 for holding a volume of liquid, which in this case, will be wash water and rinse water for delivery into the main milk pipeline 2 so that the volume of wash water or rinse water flows through the main milk pipeline 2 with full flow characteristics is connected into the main milk pipeline 2 at the upstream end 3 thereof. The apparatus 20 is charged with the wash water or rinse water through the wash line 15 which is also connected to the apparatus 20, as will be described below.
The apparatus 20 comprises a housing, in this case, provided by a cylindrical outer shell 22 which is sealably closed at the top by an outer top wall 23, and at the bottom by a base 24. Annular seals 26 seal the outer top wall 23 and the base 24 to the outer shell
22. Three tie rods 21 secure the outer top wall 23, the base 24 and the outer shell 22 together. The outer shell 22, the outer top wall 23 and the base 24 define a enclosed hollow interior region 25 which is divided by an inner cylindrical wall 27 which extends upwardly from the base 24 to form an annular holding chamber 28 for holding the volume of wash water or rinse water, and a discharge chamber 30, around which the holding chamber 28 extends. The volume of wash water or rinse water is delivered into the discharge chamber 30, and is in turn discharged into the main milk pipeline 2 from the discharge chamber 30. A main outlet 32 from the discharge chamber 30 extends from the base 24 for connecting the apparatus 20 to the main milk line 2 for delivering the volume of water thereto. The inner cylindrical wall 27 terminates at 33 short of the top wall 23, and forms a weir 34 which in turn forms a communicating outlet 31 from the holding chamber 28 through which the volume of water held in the holding chamber 28 is delivered into the discharge chamber 30. The inner cylindrical wall 27 also acts to retain the volume of water in the holding chamber 28.
A cylindrical bulkhead 35 extends downwardly from an inner top wall 36, and divides the holding chamber 28 into an inner annular compartment 37 and an outer annular compartment 38. The cylindrical bulkhead 35 terminates at 39 short of the base 24, and defines with the base 24 an annular communicating opening 40 between the inner and outer compartments 37 and 38. The inner top wall 36 is secured to the outer top wall 23 by screws (not shown), and is spaced apart therefrom by three circumferentially spaced apart spacers 42 for facilitating communication between the top portions of the outer compartment 38 between the outer top wall 23 and the inner top wall 36.
A main inlet 44 for charging the holding chamber 28 with the volume of wash or rinse water is located in the base 24 for connecting to the wash line 15.
A secondary inlet 45 is located in the outer top wall 23 for communicating the holding chamber 28 with atmosphere for applying a pressure differential across the volume of water when a vacuum is applied to the main milk pipeline 2 for urging the volume of water from the holding chamber 28 through the discharge chamber 30, and in turn, into the main milk pipeline 2 to flow through the main milk pipeline 2 with full flow characteristics. The secondary outlet 45 terminates in a valve means, in this case, a diaphragm valve 47 which selectively communicates the secondary outlet 45 through a port 48 in the valve 47 with atmosphere. The valve 47 is a typical diaphragm valve which is operated by vacuum, and is connected to a vacuum line 49 of the vacuum system 10 through a solenoid control valve 50. The solenoid control valve 50 is mounted on the diaphragm valve 47, and selectively applies vacuum to a port 51 of the valve 47 for operating a diaphragm 52 of the valve 47 for selectively communicating the secondary outlet 45 with the port 48.
The secondary inlet 45 communicates with the outer compartment 38 through the space between the inner top wall 36 and the outer top wall 23 for applying atmospheric air pressure to the surface of the volume of water in the outer compartment 38. Accordingly, the cylindrical bulkhead 35 effectively forms the inner and outer compartment 37 and 38 respectively into a Ushaped water seal between the secondary inlet 45 and the communicating outlet 31, and in turn the main outlet 32. Thus, on the holding chamber being charged with a volume of wash or rinse water, and on a vacuum being applied to the main milk pipeline 2, and on the valve 47 being operated to communicate the secondary inlet 45 with the port 48 a pressure differential, being the difference in pressure between the vacuum in the main milk pipeline 2 and atmospheric pressure is applied across the volume of water in the holding chamber 28, which thus, drives the volume of water rapidly from the holding chamber 28 into the discharge chamber 30, and in turn through the main milk pipeline
2 to flow through the main milk pipeline 2 as a plug of water with full flow characteristics.
In this embodiment of the invention the volume of the holding chamber 28 is approximately 7,500cc, and this has been found sufficient to cause the volume of water from the holding chamber 28 to flow through a main milk pipeline 2 of internal diameter 50mm with full flow characteristics when a vacuum of approximately half an atmosphere is applied to the main milk pipeline 2.
In use, when it is desired to wash the apparatus 1, an appropriate wash water solution is placed in the trough 16, and the jetters 18 are connected to the clusters 7. The control valve 50 is operated to close the valve 47 for isolating the secondary inlet 45 from the port 48, and a vacuum is applied through the vacuum line 11 to the receiver 5. This draws the wash water from the trough 16 through the wash line 15, through the apparatus 20 and in turn into the main milk pipeline 2. The water is also drawn into the main milk pipeline 2 from the wash line 15 through the jetters 18 and the clusters 7. The wash water which is drawn through the main milk pipeline 2 through the apparatus 20 is drawn into the holding chamber 28 through the main inlet 44. Since the entire system is under vacuum, including the hollow interior region 25 of the apparatus 20 the wash water is drawn upwardly into the outer compartment 38, to a level relatively close to the inner top wall 26. The vacuum in the main milk pipeline 2 further draws the wash water through the inner compartment 37 where it flows over the weir 34, and in turn, into the discharge chamber 30 for delivery through the main outlet 32, and into the main milk pipeline 2. During this phase of the washing operation the holding chamber 28, including the inner and outer compartments 37 and 38, respectively are full of wash water. At an appropriate time, or times during the time wash water is being drawn through the apparatus 1, the control valve 50 is operated for opening the valve 47 for communicating the secondary inlet 45 with the port 48. This, thus applies atmospheric pressure to the volume of water in the holding chamber 28 which causes the volume of water to surge out of the holding chamber 28 into the discharge chamber 30, and in turn, through the main milk pipeline 2 where it flows with full flow characteristics as a plug of water. On closing the valve 47, the holding chamber 28 is again charged with wash water and by opening the valve 47 a further surge of wash water from the holding chamber 28 is urged through the milk pipeline 2. Operation of the milking apparatus 1 and the apparatus 20 during rinsing with rinse water is similar to that just described for washing with wash water.
The invention is not limited to the embodiment hereinbefore described which may be varied in construction and detail.
