Abstract

The Equipment acting as a regulator for controlling the cooling depending on pressure above and underneath the grate. The regulator acting as a smooth nozzle which has variable cross section. The nozzle has round edges which reduce losses in flow and increase clinker cooler performance.

Description

DOUBLE FLAP FLOW CONTROL VALVE

Technical Field :-

Cement Industry

Background Art :

The old equipment only control the flow rate , but not care the air stream profile so that to much friction losses in old (Existing ) regulators of all different types.

Disclosure of Invention :-

First, the main parts of the regulator: -

This organizer is made up as shown in No. (1 ) Of 6 main parts are: -

1 ) Regulator body (casing) (Part No. 1 in drawing no1 ).

2) Cooling air flow gate consisting of two circular quarters (Part 2 in drawing no 1 ).

3) A controller which control the movement of double flap gate (Part No. 3 drawing no1 ).

4) Counter weight (if used instead of the controller drawing no5).

5) Arm of the transmission between the controller and the flap gate (part no4 in drawing no1 )

6) Pin link flap gate in the body of the regulator (part No.5 drawing no1 ). Brief Description of Drawings:

2) The flap

3) The controller

4) Arm of the transmission

5) The pin

Figure 2) the regulator body

The body is made of the sheet metal, consists of four slices (slices of used fibers in the form) To be parallel rectangles, hollow with dimensions of 100 mm length of x100 mm Width x200 mm height and thickness of the body 3 mm with an opening of 50 mm (W) x100 mm high on both sides of the body to install the flap gate (Part 2 of the regulator) as well as there are holes circular diameter 10 mm on each side of the body to install a flap gate pin in the regulator body and there are four threaded holes (screws) in the other two sides to install the controller which control the movement of the flap gate .

Important note:-

[Change the dimensions and materials in accordance with the requirements of the clinker cooler design flow rate of air cooling and mechanical stresses]

Figure 3) Double Flap gate the gate consists of two parts air cooling each part is a quarter of a hollow cylinder base diameter 50 mm height 100 mm thickness of 3 mm from one of its sides open to allow air to enter to move the gate against the controller spring or (counter weight if used).

the gate welded with cylindrical pin with internal diameter 10 mm and outside diameter 20 mm and a length of 00 mm for installation pin of linking the gate in the regulator body by (two nails screws 6 mm diameter).

Important note: -

Figure 4 ) controller

This part of the body of cylindrical hollow inner diameter 12 mm and outside diameter 20 mm length of 100 mm is installed in the above thread (screw) and nut in order to control the movement of double flap gate, and inside spring with diameter 10 mm and passes from the bottom, pin to connect with the arm of the transfer of movement between control device and the flap gate the air cooling device also has two10 mm diameter holes to be installed in the regulator body .

Important note: -

Figure 5) Counter weight Made from cylindrical mass of iron is used instead of the controller to control the movement of the double flap gate .

(Used in case of fixed cooling units and for easy manufacturing , while the controller used in case of moved cooling units)

Figure 6) Arm of the transmission

Which connect controller with double flap gate

it is a rectangular section part with rotation in both ends as shown in drawing No. (6) and the circular hole diameter 10 mm and the assembly with flap gate through pin connectivity and that by circlip.

And the other end by longitudinal view opened 10 mm in order to link the controller, The job of the arm of the transmission is the transmission of movement between the controller and the flap gate of the cooling air (or suspension of weight equivalent, if used instead of the e controller).

Important note: -

Figure 7) Pin which link the flap gate with the regulator body

This pin is a cylinder of solid two-steps of different diameter of 10 mm and a length of 100 mm having two the threads 6 mm in order to install the flap gate in the pin by two screws 6 mm, and then hang the gate in the regulator body the pin

Important note: -

Third, the method of operation: -

1 ) cooling air flow rate depends on the difference in pressure between the air pressure above the grate (clinker layer) and the cooling air pressure from the cooling fans underneath the grate in the cooling chamber (see Drawing No. 1 ).

2) The result of this difference in pressure, the air inside the chamber (under the grate) will press the flap gate against the controller spring (or counter weight if

used), controlling the cooling air flow rate. 3) According to adjust the compression spring of controller (counter weight value) that is calibrated to match the difference in pressure between the cooling Chamber and draft above the clinker layer.

4) The movement between the flap gate and the controller (or counterweight if used) well be transmitted through the arm of transmission and the pin.
