Abstract

An apparatus for batched mixing of an additive component from individual components for mixture products containing the additive component and for temporarily storing the additive component, which is part of a mixer for forming the mixture products by mixing an additive component with a base component includes a single batch tank connected by at least a control valve and/or a proportioning valve to connections supplying the individual components for proportioned introduction of the individual components. The single batch tank is connected to a mixing and buffer tank arranged on a level below the single batch tank for temporary storage of the mixed additive component.

First claim

The invention claimed is:

1. An apparatus for batched mixing of at least a first liquid individual component and a second liquid individual component to form an additive component and to store said additive component, said apparatus being part of a mixer for forming a mixture product by mixing said additive component with a base component, said apparatus comprising a first fluid connection, a first valve, a single-batch tank, a second fluid connection, a mixing-and-buffer tank, a second valve, a master line, and a vacuum source, wherein said first fluid connection is a physical line that connects to a source of said first individual component, wherein said first valve connects said single-batch tank to said first fluid connection, wherein said vacuum source is configured for vacuum-assisted feeding of said first and second individual components into said single-batch tank, and away from said mixing-and-buffer tank, wherein, in operation, said vacuum source causes a pressure difference that urges a component to move away from said mixing-and-buffer tank and toward said single-batch tank, wherein said second fluid connection is a physical line that connects to a source of said second individual component, wherein said master line connects said mixing-and-buffer tank to said single-batch tank, wherein said second valve connects said single-batch tank to said second fluid connection, wherein said mixing-and-buffer tank provides temporary storage of said additive component and is located upstream of where said additive component and said base component are first mixed together, wherein said mixing-and-buffer tank is arranged on a level below said single-batch tank such that said first individual component and said second individual component are discharged in free fall into said mixing-and-buffer tank, wherein, in operation, said first individual component is a liquid that flows through said first fluid connection, wherein, in operation, said second individual component is a liquid that flows through said second fluid connection, wherein, in operation, said first fluid connection supplies said first individual component for mixing to make said additive component, wherein, in operation, said second fluid connection supplies said second individual component for mixing to make said additive component, wherein said first and second fluid connections are connections that are configured for connecting to a source of liquid, and wherein said first valve is selected from the group consisting of a proportioning valve and a control valve.

2. The apparatus of claim 1 , further comprising a source of negative pressure, wherein said source of negative pressure is configured for feeding said individual components into said single-batch tank by negative pressure.

3. The apparatus of claim 1 , further comprising a common proportioning line and a plurality of valves, wherein said common proportioning line receives individual components from each of said fluid connections, wherein each valve from said plurality of valves is connected to said common proportioning line, wherein each valve from said plurality of valves controls flow of one of said individual components into said common proportioning line, wherein, said plurality of valves has, as an intended use thereof, controlling flow of individual components, wherein, to implement said intended use, said plurality of valves comprises structure for causing said valves to engage time-delayed proportioned introduction of said individual components into said single-batch tank during a proportioning cycle.

4. The apparatus of claim 3 , further comprising means for at least one of capturing and measuring of a particular quantity of each individual component introduced during a proportioning cycle into said single-batch tank, said means for at least one of capturing and measuring comprising a measuring device arranged in at least one proportioning line.

5. The apparatus of claim 4 , wherein said measuring device comprises a flow meter.

6. The apparatus of claim 1 , further comprising a dedicated proportioning line that is connected to a source of an associated individual component, said apparatus having, as an intended purpose thereof, control over relative amounts of individual components, wherein, in order to implement said intended purpose, said apparatus further comprises structure for achieving said intended purpose by controlling valves to cause said associated individual component to be present in an amount that, compared with other individual components, constitutes the greatest fraction in the mixed additive component.

7. The apparatus of claim 1 , further comprising a circuit for said additive component, said circuit comprising said mixing-and-buffer tank and a pump, wherein said pump is configured for delivering said additive component to a mixing location where admixing of said additive component to said base component takes place, wherein said pump is selected from the group consisting of a proportioning pump and a circulating pump, and wherein said mixing location is selected from the group consisting of a mixing section and a mixing position.

8. The apparatus of claim 1 , wherein said single-batch tank comprises an inlet and outlet, wherein said inlet and said outlet of said single-batch tank are connected by a controlled liquid connection to said mixing-and-buffer tank, wherein said apparatus has, as an intended use thereof, dividing time into proportioning cycles and causing feeding of different individual components during different proportioning cycles, wherein, to implement said intended use, said apparatus further comprises structure that causes proportioned feeding of said individual components into said single-batch tank takes place during a respective proportioning cycle, and wherein said structure further causes draining of said individual components from said single-batch tank takes place over said controlled liquid connection following completion of said respective proportioning cycle.

9. The apparatus of claim 1 , further comprising means for at least one of capturing and measuring of a particular quantity of each individual component introduced during a proportioning cycle into said single-batch tank, said means for at least one of capturing and measuring comprising a measuring device arranged in at least one proportioning line.

10. The apparatus of claim 9 , wherein said measuring device comprises a flow meter.

11. The apparatus of claim 1 , wherein said single-batch tank comprises an independent measuring device for at least one of capturing and measuring a quantity of at least one individual component introduced into said single-batch tank during a respective proportioning cycle.

12. The apparatus of claim 1 , further comprising a degassing element that is used for degassing said base component, wherein degassing element provides a vacuum for feeding individual components into said single-batch tank, and wherein an interior of said single-batch tank is connected by a controlled connection to an interior of said degassing element.

13. The apparatus of claim 1 , further comprising a cross valve, wherein said mixing-and-buffer tank is connected, via said cross valve, to said mixing location for admixing said additive component into said base component.

14. The apparatus of claim 13 , wherein said cross-valve comprises a first port, a second port, a third port, a fourth port, a first fluid connection, a second fluid connection, and a third fluid connection, wherein said first fluid connection connects said first port to said second port, wherein said second fluid connection connects said third port to said fourth port
