Abstract

An improved air handing system for a particulate metering system is provided. The system includes a flow path with an inlet in communication with an intake and an outlet in communication with one or more discharge points. A blower can be in communication with the flow path at the intake and provide an air flow to the flow path. The system can include a plenum within the flow path and in fluid communication with the blower. A plurality of ports can be disposed on the plenum and within the flow path. Each of the ports can be in communication with a discharge point. The system can further include air flow directing members within the flow path. Each of the air flow directing members can be in communication with a separate one of the ports and one of the discharge points.

Claims

1. An air control system for a particulate meter, the air control system comprising:

an air origin generating an air flow path;

a plenum having a plurality of discharge ports, the plenum being in fluid communication with the air origin and comprising a first portion of the air flow path;

a plurality of particulate accelerators comprising a second portion of the air flow path, each of the plurality of particulate accelerators connected to one of the plurality of discharge ports of the plenum and having;

a. an air inlet;

b. a plurality of particulate inputs;

c. an air-particulate output; and

d. a flow-directing members;

a plurality of discharge lines comprising a third portion of the air flow path, each of the plurality of discharge lines connected to the air-particulate output of each of the plurality of particulate accelerators;

wherein the flow-directing member of each of the plurality of particulate accelerators imparts at least one directional bend in the air flow path within each of the plurality of particulate accelerators.

2. The air control system of claim 1, further comprising:

a particulate accelerator flow angle defined between a direction of the air flow path at the inlet of each of the plurality of particulate accelerators and the direction of the air flow path at the air-particulate output of each of the plurality of particulate accelerators, wherein the particulate accelerator flow angle is acute.

3. The air control system of claim 2 wherein the particulate accelerator flow angle is between thirty and sixty degrees.

4. The air control system of claim 1, further comprising:

a plenum output angle defined between a direction of the air flow within the plenum and a direction of the air flow at the inlet of each of the plurality of accelerators, wherein the plenum output angle is acute.

5. The air control system of claim 1, further comprising:

a vertical descent direction of particulate after entering each of the plurality of particulate accelerators at the plurality of particulate inputs; and

an air-particulate angle defined between the vertical descent direction of the particulate and a direction of the air flow path at the air-particulate output of each of the plurality of accelerators,

wherein the air-particulate angle is acute.

6. The air control system of claim 1 wherein the flow-directing member of each of the plurality of particulate accelerators results in particulate being suspended within a fluid bed within each of the plurality of discharge lines.

7. The air control system of claim 1 wherein the air origin is a blower.

8. The air control system of claim 1, further comprising:

a confluence of the air flow path and particulate within a lower portion of each of the plurality of particulate accelerators.

9. The air control system of claim 8 wherein the particulate flow path is not parallel to the air flow path at the confluence, wherein the particulate flow path is substantially parallel to the air flow path at the air-particulate output.

10. A plurality of particulate accelerators, each of the plurality of particulate accelerators comprising:

an inlet configured to receive a flow of air from an air source;

an outlet configured to provide a flow of a mixture of the flow air and one or more types of particulates;

a main body associated with the inlet and the outlet, the main body having a curvilinear back wall and defining an enclosed volume;

a plurality of side openings disposed on the main body, each of the plurality of side openings configured to receive one of the one or more types of particulate from one of a plurality of particulate sources; and

a mixing area comprised of a portion of the enclosed volume of the main body below the plurality of side openings;

wherein the curvilinear back wall imparts at least one directional bend in the flow of air between the inlet and the mixing area,

wherein a confluence of the one or more types of particulate and the flow of air occurs within the mixing areas.

11. The plurality of particulate accelerators of claim 10, further comprising:

a plenum in fluid connection with the air source and the plurality of particulate accelerators, the plenum having a plurality of ports;

wherein the inlet of one of the plurality of particulate accelerators is connected to one of the plurality of ports on the plenum.

12. The plurality of particulate accelerators of claim 10, each particulate accelerator further comprising:

an inlet flow direction associated with the flow of air at the inlet;

an outlet flow direction associated with the flow of air at the outlet; and

an angle between the inlet flow direction and the outlet flow direction, wherein the angle is acute.

13. The plurality of particulate accelerators of claim 10 wherein the main body of each of the plurality of particulate accelerators is substantially cylindrical.

14. The plurality of particulate accelerators of claim 10 wherein the air source provides the flow of air to each of the plurality of particulate accelerators.
