Description

Technical Field

[0002] Ferroalloy ore furnaces mainly produce ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and are also used in the production of chemical raw materials such as calcium carbide.

[0003] The process of distributing the charge in the ferroalloy ore furnace can ensure that the charge is evenly distributed in the ore furnace to avoid local accumulation or sparseness. This uniform distribution helps to evenly transfer heat and reducing gas, thereby improving smelting efficiency. When the charge is evenly distributed, heat can be more effectively transferred to the charge, allowing it to reach the smelting temperature faster. At the same time, the reducing gas can also react with the charge more evenly, accelerating the reduction process.

[0004] In most of the existing rotary distribution devices of ferroalloy ore furnaces, materials come out of the distribution pipe and fall into the ferroalloy ore furnace. This device allows the distribution pipe to rotate around the upper opening of the ferroalloy ore furnace during distribution, so as to achieve uniform distribution in the ferroalloy ore furnace. However, the distribution pipe has only one discharge port. During the rotation process, the material can only be distributed in a circle around the inner and outer periphery of the ferroalloy ore furnace.

After the laying operation is completed, installation component 2 and support component 6 are opened to lift rotating component 5 to a higher position so that rotating component 5 will not hinder the subsequent smelting process.

[0028] Specifically, in order to achieve uniform distribution of materials in the ore-fired furnace 7, thereby improving the smelting efficiency of the ferroalloy, refer to Figure 3 The mounting assembly 2 includes a fixed long plate 22, the feeding assembly 3 is fixedly connected to the upper left portion of the fixed long plate 22, the lower left portion of the fixed long plate 22 is symmetrically provided with a lifting assembly 21, and the lower left portion of the fixed long plate 22 is fixedly connected to a fixed frame 23; the lifting assembly 21 includes a support column 211, the support column 211 is fixedly connected to the upper left portion of the fixed ring 1, a hydraulic cylinder 212 is fixedly connected to the lower side of the inner surface of the support column 211, a support column 213 is fixedly connected to the upper end of the piston rod of the output end of the hydraulic cylinder 212, the support column 213 is slidably connected to the inner surface of the support column 211, and the support column 213 is fixedly connected to the lower left portion of the fixed long plate 22.

[0029] Further reading Figure 4The driving assembly 4 includes a servo motor 41, which is fixedly connected to the left portion of the lower end of the fixed long plate 22. The output end of the servo motor 41 is fixedly connected to a rotating rod 1 42 through a coupling. The outer surface of the rotating rod 1 42 is fixedly connected to a driving gear 43, and the outer surface of the driving gear 43 is sleeved with a chain 44; the rotating assembly 5 includes a rotating rod 2 51, which is rotatably connected to the right portion of the upper end of the horizontal portion of the fixed frame 23, and the middle portion of the outer surface of the rotating rod 2 51 is fixedly connected to a driven gear 52, and the chain 44 is sleeved on the driven gear 52 On the outer surface, a cloth assembly 53 is arranged at the upper end of the second rotating rod 51; the cloth assembly 53 includes a cloth box 533, the cloth box 533 is fixedly connected to the upper end of the second rotating rod 51, the feeding assembly 3 is fixedly connected to and penetrates the left part of the upper end of the cloth box 533, the left end of the cloth box 533 is fixedly connected to the motor 531, the output end of the motor 531 is fixedly connected to the spiral rod 532 through a coupling, the right end of the spiral rod 532 penetrates the left end of the cloth box 533 and extends into the cloth box 533, and a plurality of discharge holes 534 are opened at the lower end of the cloth box 533.

[0030] The above-mentioned feeding assembly 3 is composed of a retaining frame fixedly connected to the left part of the upper end of the fixed long plate 22, a feeding funnel fixedly connected to the inner surface of the retaining frame, and a feeding hose with redundant length fixedly connected to the feeding funnel, wherein the feeding hose is fixedly connected to and penetrates the material distribution box 533, so that during the rotation of the material distribution box 533, the feeding assembly 3 will not hinder the rotation of the material distribution box 533;

[0031] The feed hose mentioned above can adopt the stainless steel bellows in the prior art.

[0032] The driving gear 43 and the driven gear 52 are both meshed with the chain 44;

[0033] The servo motor 41 is a mature technical means in the prior art. This solution only uses its function of controlling the rotation speed, number of rotations and start and stop of the object at any time. Its structure and working principle will not be further elaborated here.

[0034] In a specific implementation, the two hydraulic cylinders 1 212 are turned on and the piston rods are retracted at the same time, thereby driving the two support columns 213 to slide into the two support columns 1 211 respectively, thereby driving the fixed long plate 22 to descend, thereby driving the rotating assembly 5 to descend, until the rotating assembly 5 is adjusted to a position that is convenient for distributing materials in the ore-fired furnace 7;

[0035] In this way, the position of the rotating assembly 5 is lowered, so that the distance for the materials coming out of the distribution assembly 53 to fall into the submerged arc furnace 7 becomes shorter, and the rotating assembly 5 is prevented from being too high, and the impact force of the materials coming out of the distribution assembly 53 falling into the submerged arc furnace 7 is too large, thereby causing damage to the materials and the submerged arc furnace 7;

[0036] Then, the material to be spread is put into the material distribution box 533 from the feeding assembly 3, and the servo motor 41 is turned on to drive the rotating rod 1 42 to rotate clockwise, thereby driving the driving gear 43 to rotate. Under the transmission action of the chain 44, the driving gear 43 rotates to drive the driven gear 52 to rotate, thereby driving the rotating rod 2 51 to rotate, thereby driving the material distribution box 533 to rotate clockwise;

[0037] When the material distribution box 533 rotates clockwise by a certain angle and is about to contact the fixed frame 23, the servo motor 41 is turned on to drive the rotating rod 42 to rotate counterclockwise. Under the same working principle, the material distribution box 533 rotates counterclockwise by a certain angle, and when it is about to contact the fixed frame 23, the servo motor 41 is turned on to drive the rotating rod 42 to rotate clockwise. In this way, the material distribution box is controlled to rotate clockwise and counterclockwise repeatedly by a certain angle to distribute materials in the ore furnace 7.

[0038] The rotation angle range of the fabric box 533 mentioned above is between 0 and 300 degrees, which is used to ensure that the rotating component 5 and the supporting component 6 will not interfere with the driving component 4 during the rotation process. The specific rotation angle can also be adjusted according to the actual production process.

[0039] At the same time, the motor 531 is turned on to drive the screw rod 532 to rotate, and the material entering the distribution box 533 is transported from left to right, so that the material entering the distribution box 533 goes out from a plurality of discharge holes 534 and falls into the submerged arc furnace 7, thereby realizing the distribution work in the submerged arc furnace 7;

[0040] Since the screw rod 532 rotates, the material entering the material distribution box 533 is transported from left to right, and falls into the submerged arc furnace 7 from a plurality of discharge holes 534, so the material falling into the submerged arc furnace 7 is spread in a straight line in the submerged arc furnace 7;

[0041] While the material distribution component 53 is running and spreading the material in the ore-heating furnace 7, the entire material distribution box 533 is rotating repeatedly in a clockwise and counterclockwise direction, so the material discharged from the plurality of discharge holes 534 will rotate continuously in the material distribution box 533 and be evenly distributed throughout the ore-heating furnace 7, thereby achieving uniform material distribution in the ore-heating furnace 7, which helps to improve the efficiency of ferroalloy smelting.

[0042] Specifically, in order to increase the stability of the rotating assembly 5 during the cloth rotation process, refer to Figure 5The supporting assembly 6 includes a connecting column 61 and a circular slide 65. The connecting column 61 is fixedly connected to the right end of the material distribution box 533, and the circular slide 65 is fixedly connected to the upper side of the outer surface of the ore-forming furnace 7. A hydraulic cylinder 2 62 is fixedly connected to the upper side of the inner surface of the connecting column 61. A fixed column 63 is fixedly connected to the lower end of the piston rod at the output end of the hydraulic cylinder 2 62. The fixed column 63 is slidably connected to the inner surface of the connecting column 61. A ball 64 is fixedly connected to the lower end of the fixed column 63, and the ball 64 is slidably connected to the inner surface of the circular slide 65.

[0043] In a specific implementation, while the two hydraulic cylinders 1 212 are turned on to extend and retract the piston rods to adjust the height of the rotating assembly 5, the hydraulic cylinder 2 62 is turned on to synchronously extend and retract the piston rods to adjust the lengths of the connecting column 61 and the fixed column 63, so that the ball 64 can always maintain a sliding connection state in the circular slide 65;

[0044] At the same time, the lengths of the connecting column 61 and the fixing column 63 can be adjusted along with the height adjustment of the rotating assembly 5, so that the supporting assembly 6 will not hinder the height adjustment process of the rotating assembly 5.

[0045] When rotating the cloth, the cloth box 533 rotates, which will drive the connecting column 61 and the fixed column 63 to rotate as well. At this time, the ball 64 will continue to slide in the circular slide 65, so that the connecting column 61 and the fixed column 63 can provide support for the cloth box 533 during the rotating cloth process of the cloth box 533, so that the cloth box 533 can maintain balance during the rotation process, thereby improving the stability of the rotating cloth of the cloth assembly 53 without hindering the rotation process of the cloth box 533.

[0046] After the material distribution operation in the ore-fired furnace 7 is completed, the two hydraulic cylinders 1 212 and 2 62 are opened to extend the piston rods at the same time, so that the position of the rotating assembly 5 is raised, so that the rotating assembly 5 will not hinder other subsequent ferroalloy smelting work.

[0047] It should be noted that the specific installation method, circuit connection method and control method of the two hydraulic cylinders 212, servo motor 41, motor 531 and hydraulic cylinder 62 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0048] The working principle of the utility model is:

[0049] Open the two hydraulic cylinders 1 212 and 2 62 to retract the piston rods at the same time, thereby driving the rotating assembly 5 to descend, until the rotating assembly 5 is adjusted to a position convenient for distributing materials in the ore-fired furnace 7;

[0050] The material to be spread is put into the material distribution box 533 from the feeding assembly 3, and the servo motor 41 is turned on to drive the rotating rod 1 42 to rotate, thereby driving the driving gear 43 to rotate. Under the transmission action of the chain 44, the driving gear 43 rotates to drive the driven gear 52 to rotate, thereby driving the rotating rod 2 51 to rotate, thereby driving the material distribution box 533 to rotate;

[0051] At the same time, the motor 531 is turned on to drive the screw rod 532 to rotate, and the material entering the distribution box 533 is transported from left to right, so that the material entering the distribution box 533 goes out from a plurality of discharge holes 534 and falls into the submerged arc furnace 7, thereby realizing the distribution work in the submerged arc furnace 7;

[0052] When the material distribution box 533 rotates to distribute material in the ore-fired furnace 7, it will drive the connecting column 61 and the fixed column 63 to rotate synchronously, and at this time, the ball 64 will continue to slide in the circular slide 65;

[0053] After the material distribution operation in the ore-fired furnace 7 is completed, the two hydraulic cylinders 1 212 and 2 62 are opened to extend the piston rods at the same time, and the rotating assembly 5 is adjusted to a higher position.
