Abstract

Abstract An in-line blender for blending components in the form of liquid or other fluent materials comprises a pipeline 16 having a plurality of injection points 17, each injection point being connected to a set of selector valves 26 each connected to a separate source 10 of component. Only one of these selector valves at a time is connected to the injection point 17. Between the set of valves 26 and the injection point 17 there is mounted a metering apparatus in the form of a positive displacement pump 13 and a meter 14.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 194 words
An in-line blender for blending components in the form of liquid or other fluent materials comprising a pipeline 16, a plurality of injection points 17 in said pipeline, characterised in that there is provided a respective set of selector valves 26 in series adjacent to one another connected to each injection point 17, each selector valve 26 being movable between two positions, in a first position connecting an outlet 27 of that valve 26 with the supply 10 of a respecive one component and in a second position interconnecting the selector valves 26 which are downstream and upstream of it, the selector valves 26 of each set-of selector valves which is furthest downstream being connected to a metering apparatus 13, 14, 15 and thence to the associated injection point 17, and means 35, to control the selector valves whereby, during operation, only one of the selector valves 26 in each set of selector valves is in the first position and the others are in the second position so that, for each set of selector valves 26, the component from said only one of.the selector valves 26 is metered to the associated injection point 17.
Claim 2
Dependent Claim 194 words
An in-line blender for blending components in the form of liquid or other fluent materials comprising a pipeline 16, a plurality of injection points 17 in said pipeline, characterised in that there is provided a respective set of selector valves 26 in series adjacent to one another connected to each injection point 17, each selector valve 26 being movable between two positions, in a first position connecting an outlet 27 of that valve 26 with the supply 10 of a respecive one component and in a second position interconnecting the selector valves 26 which are downstream and upstream of it, the selector valves 26 of each set-of selector valves which is furthest downstream being connected to a metering apparatus 13, 14, 15 and thence to the associated injection point 17, and means 35, to control the selector valves whereby, during operation, only one of the selector valves 26 in each set of selector valves is in the first position and the others are in the second position so that, for each set of selector valves 26, the component from said only one of.the selector valves 26 is metered to the associated injection point 17.
Claim 3
Dependent Claim 32 words
An in-line blender as claimed in claim 1 characterised in that the selector valves 26 are "T" valves and the selector valves 26 in each set are arranged vertically above one another.
Claim 4
Dependent Claim 35 words
An in-line blender as claimed in claim 2 characterised in that a drain tap 34 is provided at the bottom of each vertically arranged set of selector valves 26 to assist drainage of the system.
Claim 5
Dependent Claim 39 words
An in-line blender as claimed in claims 2 or 3 characterised in that the metering apparatus 13, 14, 15 comprises a positive displacement pump 13 and a meter 14, 34 connected vertically above each set of sel.ector valves 26.
Claim 6
Dependent Claim 61 words
An in-line blender as claimed in claim 4 characterised in-that a bypass 32 is mounted around each meter 34 so that in use the majority of air provided downstream of the meter 34 to clean the system -will bypass the meter 34 and when the system is filling up again the majority of component will initially pass around the meter 34.
Claim 7
Dependent Claim 58 words
An in-line blender as claimed in claim 5 characterised in that above each meter 34 there is provided a member 22 through which air may be inserted and also through which the air which has been inserted is vented when the apparatus is reconnected to pass the component to be blended to prevent the air passing into-the pipeline.
Claim 8
Dependent Claim 31 words
An in-line blender as claimed in any of claims 1 to 6 characterised in that a strainer 35 is provided between each selector valve 26 and its supply 10 of component.
