METHOD FOR FILING BLENDING ORE "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of stacking a blending light source as a raw material for sintering. More particularly, the present invention relates to a residual compound optical method for reducing the component standard deviation of compound light according to an ejection position when the remaining amount of compound light is equal to or less than a reference value.

Generally, various ores produced in various origin are blended by a raw material processing facility and stored in a plurality of storage tanks. Blending materials in the storage tank are extracted in small quantities through a CFW (Compact Feeder) at the bottom of the storage tank and finally placed in the blending yard by reciprocating movement of the red knife.

In the file in which the blending raw materials are stacked at a predetermined height, the blending raw materials having the same chemical properties as the layer layers are mixed to form blended light. The batch-finished mixed light is continuously supplied to the sintering storage tank using a blending reclaimer.

The quality of the compounded light is determined by how much compounded light having the same chemical composition is dispensed, regardless of which part is emitted in the longitudinal direction of the pile file.

However, when the phenomenon such as the rinse of the reservoir of the quantitative extractor occurs during the mixing of raw materials for blending, the quality of blended light is deteriorated.

That is, when the above-mentioned phenomenon occurs, the specific amount of the specific blending raw material per unit length in the file length direction in the intermediate portion of the stacked file is changed. Therefore, the chemistry of blended light is changed according to the position of the file, and it becomes a main factor of fluctuation of the component in the length direction of the file by being released as Blending Reclaimer.

Accordingly, it is possible to prevent the occurrence of component fluctuation of the compounded light in the middle portion of the pile during the compounding light fitting process regardless of the remaining amount of compounded light in the storage tank.

For this purpose, the method of the present invention is to change the composition of the raw material of the raw material in monofilaments or monofilaments so that the same amount of the raw material of the blending raw material in the storage of the raw materials remaining in the storage tank starts from the end or end of the pile .

For this purpose, the present compacting method may be a structure for controlling the amount of the blending raw material when the remaining amount of the blending raw material remaining in the storage tank of the optimum extracting machine is less than the reference value at a specific position between the short end and the short end of the file.

Here, the specific position may be a position at which the time when the blending raw material extracted from the appropriate extractor moves to the end or the end of the file and the time at which the red marking that binds the blending raw material moves to the end or end of the file have.

It is preferable that the reference position is a monotone or a short axis of the file.

The reference value may be set as the total amount of the blending raw material extracted from the appropriate extractor until the red tick moves from the reference position to the next reference position after passing the single or short staple.

In addition, the adjustment of the extraction amount may be set to (the amount of remaining blending material in the storage tank) / (the time taken for the red tick to travel from the reference position to the next reference position beyond the short or short end).

Therefore, when the red tick reaches the end of the file or the end of the file, all the remaining raw materials in the storage tank are placed in the file, and the raw materials in the storage tank are empty to prevent the components from fluctuating in the middle of the file.

Thus, by controlling the extraction amount according to the remaining amount of the compounded light in the storage tank, it is possible to dispense the compounded light having the same chemical property from the single end to the single end along the longitudinal direction of the pile.

Thus, the blended light having the same chemical properties can be supplied to the sintering to improve the quality of the sintered ore and to improve blendohenoxy.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a combined optical stacking facility for explaining a combined optical stacking method according to the present embodiment; FIG.

In the following description, 'blending raw material' is a mixture of ores of various production sites, and 'blending raw material' refers to a single branded file formed by stacking various kinds of blending raw materials, and 'blended raw material' And forms a compound optical file.

First, referring to the above drawings, a blending optical pick-up apparatus will be described as follows.

The equipment for mixing and compacting includes a plurality of storage tanks 20 for storing a blending material mixed with various kinds of ores unloaded from a ship at an appropriate mixing ratio and a plurality of storage tanks 20 installed at a lower portion of the storage tanks 20, And a redistributor 30 for picking up the blending raw material extracted from the optimum extractor 10 with the pile 50 while reciprocating on the yard.

The optimum extractor 10 quantitatively extracts the raw material for breeding at a set extraction amount in accordance with an operation control command of the equipment.

The redemper 30 has a structure in which both ends of the pile 50 are constantly reciprocated at a predetermined speed.

One end of the file 50 is referred to as a single end (B) and the other end is referred to as a short end (A), as shown in FIG. 1, as shown in FIG.

The redetectors 30 continuously move the blending raw material extracted from the appropriate extractor 10 to the upper layer of the pile 50 while reciprocating at a constant speed between the monopod (B) and the staple (A).

Here, in order for the components of the compounded light to be constant at any position along the longitudinal direction of the pile 50, the blending raw materials having the same chemical property are started to be stacked at the single end B or the short end A, B). In addition, it is necessary to prevent the chemical composition of the blending raw material in the storage tank 20 from changing at the intermediate point of the file 50.

To this end, the present compounding photorefractive method is such that, at any position between the short and long heads A and B of the file 50, the redirector 30 moves to the short head B or the short head A of the file 50 And the time required for the blending raw material extracted in the amount set from the quantitative extractor 10 to travel from the quantitative extractor 10 to the monopod (B) or the short tail (A) of the pile 50 is matched Confirming whether or not the red marking (30) has arrived at the reference position, checking the remaining amount of the blending raw material in the storage tank (20) of the optimum extractor (10) at the reference position, And adjusting the extraction amount of the blending raw material by controlling the optimum extractor (10) when the amount is less than the reference value.

Here, the reference position varies depending on the traveling speed of the red needle 30 and the moving speed of the blending raw material.

When the red needle 30 is at the reference position, the raw material extracted from the red tip extractor is moved to the red tip when the red tip reaches the short tip (B) or the short tip (A), and the red tip starts to be started. Thus, it is possible to stack the raw material from the end or end of the file. When the red tick reaches the next reference position by switching the direction past the monopod (B) or the short tail (A), the raw material extracted from the appropriate quantity extractor has the following characteristics when the red tip reaches the short tail (A) Is moved to the stroke and is stacked. Based on the reference position, the extracted raw material from the appropriate extractor is started to be stacked at the end of the file or at the end of the file, so that the end can be completed at the end of the file.

The reference position may be any position along the length direction of the file 50, but may be a monopod (B) or a short end (A) of the file 50. To this end, the speed at which the blending raw material extracted from the appropriate extractor 10 moves to the short head B or the short head A and the speed at which the red head 30 moves from the short head B to the short head A, ) To the doodle (B).

The position of the red book 30 with respect to the longitudinal direction of the file 50 can be confirmed by a position detection sensor or the like provided on the movement path of the red book 30. As for the position determination of the redematter 30, more various structures can be applied, and it is not particularly limited.

Further, the operation change command of the proper quantity extractor 10 may be manually or automatically performed by the operator, and the controller of the proper quantity extractor 10 may calculate the operation command of the position detecting sensor, for example, And the operation change command is executed when the redoctor 30 reaches the reference position.

On the other hand, the 'remaining amount of raw material' refers to the amount of the raw material remaining in the storage tank, and the 'reference value' means the raw material amount to be compared with the actual raw material remaining amount. The reference value is the total amount of the raw materials to be laminated while the red tick moves from the shortest to the shortest or from the shortest to the shortest. Here, in order for the red tick to initiate the chucking at the chaff or starch, the extraction of the raw material from the chaff extractor should be performed when the red mark is reached at the reference position. That is, when the red tick moves in the single direction, the raw material extracted from the optimum extractor reaches the reference position, the red tick reaches the red tick when the red tick reaches the single tip, and the red tick is started. In the process of the red tick moving continuously past the doodle, the raw material extracted from the suitable ejector is moving toward the red tick. When the red tick moves to the next reference position after turning through the monotone, the extracted raw material reaches the red tick when the red tick reaches the end spot and completes the stacking.

Therefore, when the target is a suitable extractor, the total amount of the extracted raw material is changed from the dull (or dull) to the dull (or dull) while the red teeth move from the reference position to the dull or semi- will be.

The reference value can be defined as the total amount of the blending raw material extracted from the appropriate extractor until the red tick moves from the reference position to the next reference position after passing the single or short staple. Hereinafter, the reference position means a reference position where the red stroke passes through the short or short stroke, and then the direction is changed.

For example, if the extraction amount of the raw material extracted from the appropriate extractor is 300 tons / hour, and the time taken for the shift unit to move from the reference position to the next reference position is 10 minutes, It is calculated as the total amount of raw material extraction (300 tons / 60 minutes) * (10 minutes) and the value is 50 tons. The standard value is determined to be 50 tons. Therefore, when the remaining amount of the raw material remaining in the storage tank when the red tick reaches the reference position is 50 tons or less, the amount of the picked-up extractor is newly set.

When the total amount of the blending raw materials remaining in the storage tank 20 is smaller than the reference value, the blending raw material may be exhausted before the red mats 30 reach the single end B or the short end A. [

Therefore, by adjusting the amount of extraction in accordance with the remaining amount of the blending raw material in the storage tank 20 at the reference position, before the redissimilator 30 reaches the monotone B or the short tail A of the pile 50 It is possible to prevent the storage tank 20 from being exposed.

Here, the adjustment of the extraction amount is set to (the amount of remaining amount of the blending raw material in the storage tank) / (the time taken for the red tick to travel from the reference position to the next reference position beyond the short or short end).

Hereinafter, the blending optical pick-up process by the above-mentioned deposition method will be described.

In this embodiment, the operating conditions of each component are as follows.

The time taken for the blending raw material to be transferred from the appropriate quantity extractor 10 to the end of the pile 50 is 9 minutes and 50 seconds and the time to transport to the end of the pile is 12 minutes 29 seconds About 12.5 minutes). As shown in Fig. 1, the advancing direction of the red mats 30 is referred to as a forward direction and the opposite direction is referred to as a reverse direction. The traveling speed of the redematter 30 is 20 m / min. And the length of the file 50 from the shortest head (B) to the shortest head (A) is 282 m.

Under the above conditions, the reference position is determined as follows.

1) When the red knife 30 advances in the forward direction

Reference position = 282 m - (12.5 min 20 m / min) = 32 m

Therefore, the point at which the file 50 is moved from the end (A) to the end (32) of the file 50 is immediately shifted from the running time of the red tip 30 to the end point B until the blending raw material extracted from the optimum extractor 10 reaches the end The time to reach the reference position coincides with the reference position.

When the reference position is set and the red hand 30 advancing in the forward direction reaches the reference position, the controller of the proper extractor 10 confirms the reference position, (10) Execute the operation change command.

Therefore, the blending raw material extracted before the operation of the quantitative extractor 10 is put on the pile 50 together with the red needle 30 reaching the monopole (B). Then, according to the changed command, the blending raw material extracted into the new constellation becomes newly settable from the monotone (B) of the file (50).

2) When the red knob 30 advances in the reverse direction

Reference position = 282 m - (9.83 min 20 m / min) = 85.4 m

Thus, the point at which the file 50 is 85.4 m (the point 196.6 m from the end (A)) starts from the end point (B) to the end point (A) (A) is equal to the reference position.

When the reference position is set and the red hand 30 advancing in the reverse direction reaches the reference position, the controller of the proper extractor 10 confirms the reference position, (10) Execute the operation change command.

Therefore, the blending raw materials extracted before the operational change of the quantitative extractor 10 are all placed on the pile 50 together with the arrival of the red mulcher 30 at the end (A). Then, according to the changed command, the blending raw material extracted into the new constellation becomes newly settable from the end (A) of the file (50).

By confirming the reference position as described above and executing the operation change command of the appropriate quantity extractor 10 at the reference position, the new constellation of the blending raw material to which the change is applied is always fed to the single end (B) A). ≪ / RTI >

Hereinafter, the stacking process when the storage tank 20 is empty through the present compacting method will be described.

When the red teeth 30 reach the reference position A at 196.6 m when the red teeth 30 travel in the reverse direction, the controller of the right-side extractor 10 moves to the inside of the reservoir 20 Thereby confirming the remaining amount of the breeding raw material.

If the remaining amount of the blending raw material is larger than the reference value, the controller does not execute any additional command and continuously extracts the blending raw material at the currently performed extraction amount.

However, when the remaining amount of the blending raw material is smaller than the reference value, the controller that confirms this changes the extraction amount of the appropriate extractor 10.

The reference value is obtained as follows.

(196.6m + 32m) / (20m / min), the time required for the red tick to move from the reference position (196.6m at the end) to the next reference position (32m at the end) = 11.43 minutes.

When the reference value is obtained on the basis of this extraction amount, the amount of the extraction of the raw material by the appropriate extractor is usually 300 tons / hour. Therefore, the reference value is the raw material of the blending raw material extracted from the reference position to the next reference position (300 tons / 60 minutes) * (11.43 minutes) = 57.15 tons.

Therefore, if the remaining amount of the blending raw material in the storage tank is 42 tons when the red stroke advances to the reference position and the reference position is reached, then the controller (the remaining amount of the blending raw material in the storage tank) / And the time taken to reach the next reference position).

The amount of the raw material to be changed is 42 tons. Since the time taken for the red tick to travel from the reference position to the next reference position is 11.43 minutes, the amount of the blending raw material to be changed is 42 tons / 11.43 minutes = 3.67 tons / (= 220.2 tons / 60 minutes).

The appropriate extractor 10 extracts the raw material with the modified amount as described above.

When the red needle 30 reaches the end point A at the reference position, the raw material extracted by the changed extraction amount also reaches the red tick, and the starting of the raw material is started according to the changed extraction amount at the end.

The red knob 30 advances in the forward direction past the short segment A and moves toward the monotone. When the red tick is reversed in the forward direction and reaches the next reference position, the raw materials in the storage tank are all extracted by a suitable extractor. When the red tick reaches the forward reference position, the raw material is picked up when the red tick reaches the monopod (B) and reaches the monopod.

The new change can be applied in the monopne (B) or the short term (A) of the file by confirming the reference position as described above and executing the operation change command such as the extraction amount of the quantity extractor 10 at the reference position, It is possible to prevent the property change of the blending raw material accumulated in the middle portion of the file 50 from being changed.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
