Description

Technical Field

[0001] The invention relates to the technical field of batching systems, and in particular to a full-automatic batching system for a ferroalloy ore furnace and a use method thereof. Background Art

[0002] The ore-fired furnace is also called an electric arc furnace or a resistance furnace. It uses carbon or magnesium refractory materials as the furnace lining, uses self-heating electrodes, and utilizes the energy of the arc and the current to generate energy through the resistance of the charge to melt the metal. The ingredients are a prerequisite for the high quality, high yield and low consumption of the blast furnace.

[0003] Traditional automatic batching devices for submerged arc furnaces are usually equipped with a large number of electrical components and sensors, such as weighing sensors. Since the working environment of submerged arc furnaces is usually a high-temperature, high-dust environment, the sensors and control equipment in traditional automatic batching devices for submerged arc furnaces are easily affected by environmental factors such as high temperature and dust. Long-term use will cause equipment failure or reduced accuracy, or even damage. At the same time, due to the influence of the environment, the accuracy of sensors and detection equipment will decrease, which will cause large errors in the material ratio, thereby affecting the temperature and production efficiency of the hot furnace.

[0004] In the prior art, the invention patent with patent application number CN202310888504.0 discloses an automatic batching device and method for an electric arc furnace, which avoids the sensors and control equipment in the traditional automatic batching device being easily affected by the environment such as high temperature and dust. However, in the specific operation process, after the material capacity in the discharge hopper reaches the specified capacity, the first rotating rod presses the conveyor belt switch and the hydraulic cylinder switch to stop adding materials to the upper hopper, so that the material received in the discharge hopper is automatically discharged. However, when the material capacity in the discharge hopper reaches the standard and the conveyor belt stops conveying, there is still material falling from the conveyor belt falling from the upper hopper into the discharge hopper, and moving out of the discharge hopper at the same time along with the weight of the material that reaches the standard, so that the actual amount of material entering the mixing chamber is greater than the amount of material originally required to be added; and the discharge hoppers in the batching device are not related to each other, but only automatically discharge after the amount of material in the discharge hopper reaches the requirement, and the proportion of different materials is not achieved, which further affects the furnace temperature and production efficiency of the electric arc furnace.

[0020] The present invention also discloses a method for using a fully automatic batching system for a ferroalloy ore furnace, which is characterized by comprising the following steps:

[0021] S1: According to the different material requirements of the ore-fired furnace, the screw is rotated to drive the support plate to move in the material chamber, thereby adjusting the storage space for the material in the material chamber, and conveying different materials to different crushing storage boxes through the first belt conveyor, and the materials enter the crushing storage box from the discharge port;

[0022] S2: Control the operation of the first motor. When the first motor is running, it drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear on the outer side of the rotating tube. The rotating tube drives the crushing piece to crush the material in the crushing storage box. After crushing, the material with the particle size meeting the standard passes through the filter plate and enters the material cavity along the conical pressure seat.

[0023] When the first bevel gear rotates, it drives the connecting rod to rotate, and the connecting rod drives the movable tube to move up and down through the connecting rod, so that the conical pressure seat at the bottom of the movable tube moves back and forth between the bottom of the crushing storage box and the top of the material cavity;

[0024] As the material in the material cavity is gradually filled and piled up, when the conical pressure seat continues to move downward, the abutment block at the bottom of the conical pressure seat pushes the material at the top of the material cavity. At this time, the material inside the material cavity is filled, and the abutment block moves upward under the reaction force of the material, and the abutment block squeezes the airbag. The air in the airbag is introduced into the sleeve through the connecting hose, and the lower piston is forced to move upward and press the first push switch, and the first push switch controls the first motor to stop working;

[0025] S3: When the lower piston moves upward, the air in the sleeve is introduced into the air guide tube, and the air enters the pneumatic tube through the air guide tube, causing the main piston in the pneumatic tube to move upward for a distance;

[0026] As the material cavities in other material discharge seats are filled with materials, the air in the remaining air guide pipes is also guided into the pneumatic pipe. After the air in all the air guide pipes flows into the pneumatic pipe, the main piston moving upward in the pneumatic pipe can press the second push switch, and the second push switch controls the operation of the second motor.

[0027] S4: When the second motor is running, it drives the incomplete gear to mesh with the driven gear on the rotating rod, so that the rotating seats in each material discharge seat rotate along with the rotating rod connected to each seat. When the rotating seat rotates, the upper opening of the material cavity that was originally connected to the bottom opening of the crushing storage box rotates to another position. After the rotating seat rotates, the material in the material cavity automatically enters the mixing box from the feed inlet;

[0028] When the rotating seat rotates, the convex block on the fixed seat pushes the push rod intermittently, so that the push rod drives the connecting seat to move in the material cavity, and then the connecting seat drives the supporting plate to move in the material cavity through the screw, so that the material in the material cavity falls quickly, preventing the material from being blocked in the material cavity and unable to fall;

[0029] S5: The materials in each material cavity are discharged in the same batch, and the materials are discharged in proportion. With the continuous rotation of the incomplete gear, the incomplete gear is no longer meshed with the driven gear for transmission. The rotating seat drives the rotating rod to reset and rotate under the action of the torsion spring. After the material cavity of the rotating seat is connected with the lower opening of the crushing storage box again, the abutment block on the lower side of the conical pressing seat is no longer squeezed, the airbag is restored, the lower piston moves down in the sleeve, and the limit plate moves down in the air guide pipe, so that the first push switch controls the operation of the first motor again, and the second push switch no longer controls the operation of the second motor, so that a new round of materials are discharged in proportion.

[0030] S6: The different granular materials entering the mixing box are evenly mixed under the action of the stirring structure. The mixed materials are discharged from the mixing box and transported to the top of the submerged arc furnace via the second belt conveyor for loading.

[0031] Compared with the prior art, the present invention provides a fully automatic batching system for a ferroalloy ore furnace and a method for using the same, which has the following beneficial effects:

[0032] 1. The fully automatic batching system and the use method for the ferroalloy ore furnace can crush the block material into particles, which is convenient for the uniform mixing and efficient calcination of the subsequent materials, and can intuitively display the weight of the material stored per unit area in the material chamber, thereby improving the batching accuracy and avoiding the sensors and control equipment in the traditional automatic batching device from being easily affected by the environment such as high temperature and dust, thereby improving the stability and reliability of the device.

[0033] 2. The fully automatic batching system and the use method of the ferroalloy ore furnace are interconnected through the material chambers between multiple discharge seats. Only when all the material chambers are filled with materials and the air in all the sleeves flows into the pneumatic tube, the main piston moving upward in the pneumatic tube can press the second push switch. The second push switch controls the operation of the second motor to realize the flipping and unloading of all the material chambers, so that different materials can be discharged proportionally in the same batch, and after one round of unloading is completed, a new round of batching and unloading work will be automatically started. The system has a high degree of automation, reduces the work of manual participation, reduces labor costs, and thus ensures the furnace temperature and production efficiency of the ore furnace.

[0051] A driving mechanism, which is arranged on the top of the crushing storage box 4 and is used to drive the crushing assembly to work;

[0052] The driving mechanism is connected with a pressing component for pressing the material in the material cavity 5 .

[0053] Furthermore, it also includes a first belt conveyor 22 and a second belt conveyor 23 arranged on the top of the crushing storage box 4, the end of the first belt conveyor 22 is placed on the upper side of the discharge port 402, the head end of the second belt conveyor 23 is placed at the discharge port of the mixing box 1, and the second belt conveyor 23 extends toward the electric arc furnace away from one end of the mixing box 1.

[0054] Specifically, different materials are conveyed to different crushing storage boxes 4 by the first belt conveyor 22, and the materials enter the crushing storage boxes 4 from the discharge port 402.

The rotating tube 7 drives the crushing piece 701 to crush the material in the crushing storage box 4. After crushing, the material with a particle size that meets the standard passes through the filter plate 401 and enters the material chamber 5 along the conical pressure seat 801.

[0057] Example 3: Reference Figure 4-11 , a fully automatic batching system for an ferroalloy ore furnace. On the basis of Example 2, a pressing assembly includes a movable tube 8 movable in a rotating tube 7, a conical pressing seat 801 is provided at the bottom of the movable tube 8, the bottom diameter of the conical pressing seat 801 is the same as the diameter of the material cavity 5 but smaller than the inner diameter of the crushing storage box 4, a connecting rod 6021 is fixedly provided on the first bevel gear 602, and a connecting rod 6022 movably connected to the movable tube 8 is rotatably connected to the outer side of the connecting rod 6021.

[0058] Furthermore, a groove 11 is provided at the bottom of the conical pressure seat 801, a first elastic element 111 (the first elastic element 111 is set as a spring) is fixedly provided on the inner wall of the groove 11, an end of the first elastic element 111 away from the inner wall of the groove 11 is connected to an abutment block 112, an air bag 113 is provided on the inner wall of the groove 11 to movably abut against the abutment block 112, a sleeve 10 is fixedly provided on the top of the crushing storage box 4 through the support plate 9, a connecting hose 114 is provided between the air bag 113 and the sleeve 10, and the sleeve 10 A moving rod 12 is slidingly connected to the upper part, and two ends of the moving rod 12 are respectively connected to a limit plate 121 and a lower piston 122. A second elastic element 123 (the second elastic element 123 is set as a spring) is sleeved on the outer side of the moving rod 12, and two ends of the second elastic element 123 are respectively connected to the limit plate 121 and the sleeve 10. The inner wall of the sleeve 10 is fixed with a first push switch 13 electrically connected to the first motor 601. The top of the lower piston 122 is movably abutted against the first push switch 13, and the lower piston 122 is slidably connected in the sleeve 10.

[0059] Furthermore, several sleeves 10 are connected to an air guide tube 14, the limit plate 121 slides in the air guide tube 14, and the ends of the multiple air guide tubes 14 away from the sleeves 10 are connected to the same pneumatic tube 15, a main piston 151 is slidably connected in the pneumatic tube 15, a third elastic element 152 is arranged between the main piston 151 and the inner wall of the pneumatic tube 15 (the third elastic element 152 is arranged as a spring), and a second press switch 153 is arranged in the pneumatic tube 15 to resist the movement of the main piston 151.

[0060] Furthermore, a torsion spring is arranged between the rotating seat 302 and the fixed seat 301, and a rotating rod 16 is arranged on each rotating seat 302. The end of the rotating rod 16 away from the rotating seat 302 passes through the fixed seat 301 and is connected to a driven gear 161. A bracket 17 is fixed on the fixed seat 301, and a second motor 171 electrically connected to the second push switch 153 is fixed on the bracket 17. The output shaft of the second motor 171 is connected to an incomplete gear 18 intermittently meshed with the driven gear 161.

[0061] Specifically, the first motor 601 is controlled to run, and the first motor 601 drives the first bevel gear 602 to rotate when running, and the first bevel gear 602 is meshed with the second bevel gear 603 on the outer side of the rotating tube 7 for transmission, and the rotating tube 7 drives the crushing piece 701 to crush the material in the crushing storage box 4, and the material with the particle size meeting the standard after crushing passes through the filter plate 401 and enters the material cavity 5 along the conical pressure seat 801;

[0062] When the first bevel gear 602 rotates, it drives the connecting rod 6021 to rotate, and the connecting rod 6021 drives the movable tube 8 to move up and down through the connecting rod 6022, so that the conical pressure seat 801 at the bottom of the movable tube 8 moves back and forth between the bottom of the crushing storage box 4 and the top of the material cavity 5;

[0063] As the material in the material cavity 5 is gradually filled and piled up, when the conical pressing seat 801 continues to move downward, the abutting block 112 at the bottom of the conical pressing seat 801 pushes the material at the top of the material cavity 5. At this time, the material inside the material cavity 5 is filled, and the abutting block 112 moves upward under the reaction force of the material. The abutting block 112 squeezes the airbag 113, and the air in the airbag 113 is introduced into the sleeve 10 through the connecting hose 114. The lower piston 122 is forced to move upward and press the first push switch 13, and the first push switch 13 controls the first motor 601 to stop working;

[0064] When the lower piston 122 moves upward, the air in the sleeve 10 is introduced into the air guide tube 14, and the air enters the pneumatic tube 15 through the air guide tube 14, so that the main piston 151 in the pneumatic tube 15 moves upward for a distance;

[0065] As the material cavities 5 in other material discharge seats 3 are filled with materials, the air in the remaining air guide pipes 14 is also guided into the pneumatic tube 15. After the air in all the air guide pipes 14 flows into the pneumatic tube 15, the main piston 151 that moves upward in the pneumatic tube 15 can press the second push switch 153, and the second push switch 153 controls the second motor 171 to operate.

[0066] When the second motor 171 is running, it drives the incomplete gear 18 to mesh with the driven gear 161 on the rotating rod 16, so that the rotating seats 302 in each material discharge seat 3 rotate along with the rotating rod 16 connected to each other. When the rotating seat 302 rotates, the upper opening of the material chamber 5 that was originally connected to the bottom opening of the crushing storage box 4 rotates to another position. After the rotating seat 302 rotates, the material in the material chamber 5 automatically enters the mixing box 1 from the feed inlet 101;

[0067] The materials in each material chamber 5 are discharged in the same batch, and different materials are discharged in proportion. With the continuous rotation of the incomplete gear 18, the incomplete gear 18 is no longer meshed with the driven gear 161 for transmission, and the rotating seat 302 drives the rotating rod 16 to reset and rotate under the action of the torsion spring. After the material chamber 5 of the rotating seat 302 is connected with the lower end opening of the crushing storage box 4 again, the abutment block 112 on the lower side of the conical pressure seat 801 is no longer squeezed, the airbag 113 is restored, the lower piston 122 moves downward in the sleeve 10, and the limit plate 121 moves downward in the air guide tube 14, so that the first push switch 13 controls the operation of the first motor 601 again, and the second push switch 153 no longer controls the operation of the second motor 171, so as to realize a new round of proportional distribution and discharge of different materials, and after a round of discharge is completed, a new round of batching and discharge work is automatically started. The system of the present application has a high degree of automation, reduces the work of manual participation, reduces the labor cost, and thus ensures the furnace temperature and production efficiency of the ore-fired furnace.

[0068] Example 4: Reference Figure 1-6, a fully automatic batching system for an ferroalloy ore furnace. On the basis of Example 3, the capacity adjustment component includes an elastic telescopic rod 19 fixedly arranged in a material chamber 5, and the end of the elastic telescopic rod 19 away from the inner wall of the material chamber 5 is connected to a connecting seat 191, and a screw 192 is threadedly connected to the connecting seat 191, and a capacity scale line 1921 is arranged on the screw 192, and the end of the screw 192 is connected to a support plate 193 slidably connected to the material chamber 5.

[0069] Furthermore, a push rod 20 connected to the connecting seat 191 is slidably connected in the material chamber 5, and a fourth elastic element 2001 (the fourth elastic element 2001 is set as a spring) is sleeved on the push rod 20, whose two ends are respectively connected to the connecting seat 191 and the inner wall of the material chamber 5. The end of the push rod 20 away from the connecting seat 191 passes through the rotating seat 302 and extends outward, and a protrusion 21 that resists the push rod 20 is fixed on the arc-shaped inner wall of the fixed seat 301.

[0070] Specifically, for a cubic material chamber 5, according to the different material requirements of the electric arc furnace, the screw 192 is rotated so that the screw 192 drives the support plate 193 to move in the material chamber 5, thereby adjusting the storage space for the material in the material chamber 5, so that different material chambers 5 can store materials of different weights. When the rotating seat 302 rotates, the protrusion 21 on the fixed seat 301 intermittently pushes the push rod 20, so that the push rod 20 drives the connecting seat 191 to move in the material chamber 5, and then the connecting seat 191 drives the support plate 193 to move in the material chamber 5 through the screw 192, so that the material in the material chamber 5 falls quickly, and prevents the material from being blocked in the material chamber 5 and unable to fall, thereby ensuring the accurate and proportional feeding of each material, ensuring the accuracy of the ingredients, and thus ensuring the furnace temperature and production efficiency of the electric arc furnace.

[0071] The present invention also discloses a method for using a fully automatic batching system for a ferroalloy ore furnace, comprising the following steps:

[0072] S1: According to different material requirements of the ore-fired furnace, the screw 192 is rotated so that the screw 192 drives the support plate 193 to move in the material chamber 5, thereby adjusting the storage space for the material in the material chamber 5, and conveying different materials to different crushing storage boxes 4 through the first belt conveyor 22, and the materials enter the crushing storage box 4 from the discharge port 402;

[0073] S2: Control the first motor 601 to run. When the first motor 601 runs, it drives the first bevel gear 602 to rotate. The first bevel gear 602 is meshed with the second bevel gear 603 on the outer side of the rotating tube 7. The rotating tube 7 drives the crushing piece 701 to crush the material in the crushing storage box 4. After crushing, the material with the particle size meeting the standard passes through the filter plate 401 and enters the material cavity 5 along the conical pressure seat 801.

[0074] When the first bevel gear 602 rotates, it drives the connecting rod 6021 to rotate, and the connecting rod 6021 drives the movable tube 8 to move up and down through the connecting rod 6022, so that the conical pressure seat 801 at the bottom of the movable tube 8 moves back and forth between the bottom of the crushing storage box 4 and the top of the material cavity 5;

[0075] As the material in the material cavity 5 is gradually filled and piled up, when the conical pressing seat 801 continues to move downward, the abutting block 112 at the bottom of the conical pressing seat 801 pushes the material at the top of the material cavity 5. At this time, the material inside the material cavity 5 is filled, and the abutting block 112 moves upward under the reaction force of the material. The abutting block 112 squeezes the airbag 113, and the air in the airbag 113 is introduced into the sleeve 10 through the connecting hose 114. The lower piston 122 is forced to move upward and press the first push switch 13, and the first push switch 13 controls the first motor 601 to stop working;

[0076] S3: When the lower piston 122 moves upward, the air in the sleeve 10 is introduced into the air guide tube 14, and the air enters the pneumatic tube 15 through the air guide tube 14, so that the main piston 151 in the pneumatic tube 15 moves upward for a distance;

[0077] As the material cavities 5 in other material discharge seats 3 are filled with materials, the air in the remaining air guide pipes 14 is also guided into the pneumatic tube 15. After the air in all the air guide pipes 14 flows into the pneumatic tube 15, the main piston 151 that moves upward in the pneumatic tube 15 can press the second push switch 153, and the second push switch 153 controls the second motor 171 to operate.

[0078] S4: When the second motor 171 is running, it drives the incomplete gear 18 to mesh with the driven gear 161 on the rotating rod 16, so that the rotating seats 302 in each material discharge seat 3 rotate along with the rotating rod 16 connected to each of them. When the rotating seat 302 rotates, the upper opening of the material chamber 5 that was originally connected to the bottom opening of the crushing storage box 4 rotates to another position. After the rotating seat 302 rotates, the material in the material chamber 5 automatically enters the mixing box 1 from the feed inlet 101;

[0079] When the rotating seat 302 rotates, the protrusion 21 on the fixed seat 301 pushes the push rod 20 intermittently, so that the push rod 20 drives the connecting seat 191 to move in the material chamber 5, and then the connecting seat 191 drives the supporting plate 193 to move in the material chamber 5 through the screw 192, so that the material in the material chamber 5 falls quickly, preventing the material from being blocked in the material chamber 5 and unable to fall;

[0080] S5: The materials in each material cavity 5 are discharged in the same batch, and the materials are discharged in proportion. With the continuous rotation of the incomplete gear 18, the incomplete gear 18 is no longer meshed with the driven gear 161, and the rotating seat 302 drives the rotating rod 16 to reset and rotate under the action of the torsion spring. After the material cavity 5 of the rotating seat 302 is connected with the lower end opening of the crushing storage box 4 again, the abutment block 112 on the lower side of the conical pressure seat 801 is no longer squeezed, the airbag 113 is restored, the lower piston 122 moves down in the sleeve 10, and the limit plate 121 moves down in the air guide tube 14, so that the first push switch 13 controls the first motor 601 to run again, and the second push switch 153 no longer controls the second motor 171 to run, so that a new round of materials are discharged in proportion.

[0081] S6: The different granular materials entering the mixing box 1 are evenly mixed under the action of the stirring structure. The mixed materials are discharged from the mixing box 1 and conveyed to the top of the submerged arc furnace via the second belt conveyor 23 for loading.

[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

At this time, the material in the material cavity (5) is filled, and the abutment block (112) moves upward due to the reaction force of the material.
