Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smelting equipment, in particular to a mineral furnace feeding system. BACKGROUND

[0002] The mineral furnace is mainly used for reducing smelting of ore, carbonaceous reducing agent and solvent and other raw materials, also known as arc furnace or resistance furnace. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, ferromanganese-silicon alloy and other important industrial raw materials in metallurgical industry and calcium carbide and other chemical raw materials. The working characteristics of the mineral furnace are that the furnace lining is made of refractory material, the self-grown electrode is used, the electrode is inserted into the furnace charge for submerged arc operation, the energy of the electric arc and the current passing through the furnace charge are used to produce energy due to the resistance of the furnace charge to smelt the metal, the material is added successively, the slag is discharged intermittently, and it is a continuous operation of an industrial electric furnace. The basic task of the mineral furnace production is to extract metal elements from ore or oxide, and the chemical reaction in the production process of the mineral furnace is mainly the reduction reaction of oxide, and there is also the oxidation reaction of elements. The basic principle of the mineral furnace production is based on the thermodynamics of selective oxidation-reduction reaction, and the essence is that the oxide of the required element reacts with the reducing agent to generate the oxide of the main element in the reducing agent.

[0003] Some traditional smelting enterprises adopt the material pipe type feeding mode when smelting the mineral furnace. The furnace top bin arranged above the mineral furnace is transmitted to the material pipe through the vibrating feeder, and then the material pipe sends the material to the furnace hearth. Since the material pipe is usually a fixed straight pipe design, after feeding the material into the furnace hearth, the uniformity of the furnace charge is often poor, which affects the smelting quality of the mineral furnace. In order to solve this problem, the workers usually use special tools to evenly distribute the furnace charge after observation. This not only increases the labor intensity of the workers, but also prolongs the feeding time of the mineral furnace, affecting the production efficiency. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0022] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0023] As shown in the drawings, the present application discloses a kind of ore furnace feeding system, including the ore furnace main body 2 of top installation of furnace cover 1, multiple rotary distributors 3 are arranged on the furnace cover 1, multiple rotary distributors 3 are evenly distributed along the circumference of the furnace cover 1, the feed inlet of rotary distributor 3 is located above the furnace cover 1, and the discharge port of rotary distributor 3 is located in the ore furnace main body 2. Figure 1 The feed inlet of rotary distributor 3 is connected with a top bin through a pipe, and the discharge port of rotary distributor 3 can rotate in the ore furnace main body 2.

[0024] A center pipe 4 is fixedly installed at the center of the furnace cover 1 on the top of the ore furnace main body 2, the lower end of the center pipe 4 is located inside the ore furnace main body 2, and the upper end of the center pipe 4 is also connected with a top bin through a pipe.

[0025] In the above embodiment, the general process of ore furnace feeding is to lay a circular track on the platform above the ore furnace, and the track trolley carries the material in the buffer bin to the top bin (as many straight pipes as the furnace cover 1 has are connected with the top bin, and these top bins are connected with these straight pipes one by one), a release port is arranged below the track trolley, and the track trolley can add material to the corresponding top bin through the release port when it reaches the top bin to be fed. The straight pipe installed on the furnace cover 1 usually has its lower end port extending into the ore furnace, and when feeding, the material in the top bin will pass through the electric vibrator, air injection device, anti-wear elbow and straight pipe in sequence to be added to the ore furnace. Since these straight pipes are fixed, the discharged material will be obviously unevenly distributed in the ore furnace. In order to prevent uneven distribution from affecting the production quality of the material, workers often need to manually trim the material in the furnace using special tools, which not only affects the production efficiency of the required product, but also increases the labor intensity of the workers.

[0026]

[0027] ​The present application improves the plurality of straight material pipes in the circumferential direction of the furnace cover 1 in the prior art into the rotary material distributors 3 which can freely rotate in the furnace, the feeding end of the rotary material distributor 3 is connected with a furnace top bin as the traditional straight material pipe. Since there are multiple electrodes in the electric arc furnace, and the area inside the electrode (the central area of the electric furnace) is smaller than the area outside the electrode, the present application is installed with a central material pipe 4 similar to the structure of the traditional straight material pipe at the center of the furnace cover 1, which is insufficient to install the rotary material distributor 3, the diffusion range of the material discharged by the central material pipe 4 is similar to the central area of the electric furnace, so that the central material pipe 4 can evenly fill the central area of the electric furnace when pouring the material in the furnace top bin connected thereto into the electric arc furnace. The plurality of rotary material distributors 3 uniformly arranged outside the electrode along the electric arc furnace can cover as much as possible the area outside the electrode in the furnace when rotating, and work cooperatively with the central material pipe 4, so that the feeding range required by the process in the electric arc furnace can be efficiently and uniformly filled. Since the present application improves the uniformity of feeding in the electric arc furnace, the workload of workers manually leveling the material in the furnace is greatly reduced, and the time and labor required for the work are also greatly reduced, and the production efficiency of the products required by the enterprise is also effectively improved to a certain extent.

[0028] The electrode, the furnace top bin, the material pipe connected with the furnace top bin, the electric vibrator, the air injection device, the wear-resistant elbow and other feeding components all belong to the prior art, and these parts are not shown in the drawings.

[0029] Further, as shown in Figure 2 The outer support seat 31 is fixedly installed at the top of the furnace cover 1, the center of the outer support seat 31 is inserted with a lower material pipe 32, the lower end of the lower material pipe 32 passes through the furnace cover 1 downward from the bottom of the outer support seat 31 and is located in the electric arc furnace body 2, the lower material pipe 32 is rotationally connected with the outer support seat 31 and the furnace cover 1, the upper end of the lower material pipe 32 is fixedly connected with a transition pipe 33, the upper end of the transition pipe 33 is connected with a furnace top bin through a rotary joint 34, one side of the transition pipe 33 is connected with a rotary assembly 35, the rotary assembly 35 can drive the transition pipe 33 to rotate around its axis; the lower material pipe 32 is connected with a guide chute 36 which can swing in the vertical direction at the inner lower end of the electric arc furnace body 2.

[0030] In the above embodiment, the outer support seat 31 installed on the furnace cover 1 can provide a mounting base for the downcomer 32, and the downcomer 32 is rotatably connected with the outer support seat 31 and the furnace cover 1. Thus, when the transition pipe 33 fixedly connected with the downcomer 32 is driven to rotate by the rotating assembly 35, the outer support seat 31 and the furnace cover 1 will not limit the rotation. The transition pipe 33 at the upper end of the downcomer 32 is connected with the pipe below the corresponding furnace top bin through the rotary joint 34. Since the rotary joint 34 is a commonly used connecting piece that can rotate 360° to transport medium, the pipe below the furnace top bin and the transition pipe 33 can be connected while the pipe is fixed and the transition pipe 33 is freely rotatable. The downcomer 32 is connected with a guide chute 36 that can swing in the vertical direction at the lower end of the downcomer 32. When the downcomer 32 is driven to rotate around its axis by the rotating assembly 35, the guide chute 36 can uniformly distribute the material in the area covered by the guide chute 36 in the furnace during feeding, so as to ensure the continuity and uniformity of the material distribution in the area corresponding to the rotating distributor 3.

[0031] Further, as shown in Figure 2 and Figure 3 , the rotating assembly 35 includes a gear ring 351 fixedly sleeved outside the transition pipe 33, one side of the gear ring 351 is engaged with a drive gear 352, the center of the drive gear 352 is fixedly connected with the output shaft of a rotating motor 353, a motor bracket 354 is movably sleeved on the output shaft of the rotating motor 353, and the lower end of the motor bracket 354 and the housing of the rotating motor 353 are fixedly connected with the furnace cover 1.

[0032] In the above embodiment, when the rotating motor 353 on the furnace cover 1 is started, the drive gear 352 connected with the output end of the rotating motor 353 rotates, and the drive gear 352 is engaged with the gear ring 351 fixedly sleeved outside the transition pipe 33. Thus, the transition pipe 33 rotates with the downcomer 32 and the guide chute 36 under the drive of the gear ring 351 outside the transition pipe 33. Thus, the guide chute 36 can realize 360° distribution in the furnace to ensure the largest possible filling range.

[0033] Further, as shown in Figure 2 , the diameter of the drive gear 352 is smaller than the diameter of the gear ring 351.

[0034] In the above embodiment, the diameter of the driving gear 352 is set to be smaller than that of the gear ring 351, so that when the driving gear 352 drives the gear ring 351 to rotate, the driving gear 352 has a smaller circumference and rotates faster, which determines that it has a smaller torque, while the gear ring 351 has a relatively larger circumference and rotates slower, which determines that it has a larger torque. Therefore, when the pinion drives the gear, a reasonable balance between speed and torque can be achieved, so as to drive the equipment to run accurately and stably.

[0035] Further, as shown in Figure 2 and Figure 3 , one side of the lower end of the feeding pipe 32 is provided with a mounting frame 5, a horizontal rotating shaft 6 penetrates through the mounting frame 5 and is rotatably connected therebetween, the two ends of the rotating shaft 6 are fixedly connected with an opposite side wall of one end of the material guide groove 36, and the upper side of the other end of the material guide groove 36 is connected with a swing assembly 7 which can be driven to swing up and down around the rotating shaft 6.

[0036] In the above embodiment, one end of the material guide groove 36 is hingedly connected with the mounting frame 5 on the feeding pipe 32 through the rotating shaft 6, so that the other end of the material guide groove 36 is a free end which can be swung up and down around the rotating shaft 6 under the driving of the swing assembly 7. When the material guide groove 36 swings up and down, the position of the lower end of the material guide groove 36 in the horizontal direction will change, so that the material guide groove 36 can realize uniform filling of a plane in the electric arc furnace under the driving of the rotating motor 353 on the feeding pipe 32, and the flexibility of the material guide groove 36 in use is improved.

[0037] Further, as shown in Figure 3 , the swing assembly 7 includes a fixed crossbar 71 fixedly installed on the material guide groove 36, a first guide wheel 72 and a second guide wheel 73 are respectively installed on the same side of the feeding pipe 32 and the transition pipe 33, a high-temperature-resistant steel wire 74 is tied at the middle position of the fixed crossbar 71; one end of the high-temperature-resistant steel wire 74 away from the fixed crossbar 71 penetrates into the feeding pipe 32 after passing outside the first guide wheel 72, extends upward along the reserved hole channel on the side wall of the feeding pipe 32 and the transition pipe 33 to a position higher than the gear ring 351, and then extends out from one side of the transition pipe 33, and then penetrates through outside the second guide wheel 73 and is connected with the output end of a driving hydraulic cylinder 75, which is fixedly installed on the outside of the transition pipe 33 in the vertical direction.

[0038] In the above embodiments, the present application provides a channel for passing the high-temperature resistant steel wire 74 in the vertical direction in the inner wall of the downpipe 32 and the transition pipe 33 on the side away from the mounting frame 5. This can save the operation of opening a hole for the high-temperature resistant steel wire 74 on the furnace cover 1, thereby preventing the risk of flue gas in the electric arc furnace escaping from the hole opened for the high-temperature resistant steel wire 74 on the furnace cover 1. Since the high-temperature resistant steel wire 74 is laid along the channel in the inner wall of the downpipe 32 and the transition pipe 33, the material can be prevented from contaminating the high-temperature resistant steel wire 74 when flowing along the downpipe 32 and the transition pipe 33.

[0039] The first guide wheel 72, located where the high-temperature resistant steel wire 74 enters the discharge tube 32, guides it smoothly into the hole in the side wall of the discharge tube 32, reducing friction loss between the high-temperature resistant steel wire 74 and the discharge tube 32 during use. The second guide wheel 73, located where the high-temperature resistant steel wire 74 exits the transition tube 33, guides it smoothly to connect with the drive hydraulic cylinder 75. The upper end of the high-temperature resistant steel wire 74 extends from the transition tube 33 at a position higher than the gear ring 351, which prevents the high-temperature resistant steel wire 74 from interfering with the rotation of the gear ring 351.

[0040] The shell of the driving hydraulic cylinder 75 of the present application is fixed to the outside of the transition pipe 33 by a special frame, and the output end of the driving hydraulic cylinder 75 faces downward and is connected to the high-temperature resistant steel wire 74. When the range of material distribution needs to be increased, the driving hydraulic cylinder 75 is started to drag the high-temperature resistant steel wire 74 upward. At this time, the high-temperature resistant steel wire 74 will synchronously swing the free end of the guide trough 36 upward, and the overall projection length of the guide trough 36 in the horizontal plane will increase, and the material discharged from the free end of the guide trough 36 will also flow to a farther position; when a smaller range of material distribution is required, the output end of the driving hydraulic cylinder 75 is started to move downward, and the high-temperature resistant steel wire 74 will naturally swing downward under the action of gravity at the free end of the guide trough 36. At this time, the overall projection length of the guide trough 36 in the horizontal plane will be reduced, and the distance of the material discharged from the free end of the guide trough 36 will become closer. In this way, the radial length change along the discharge pipe 32 can be achieved during material distribution, thereby ensuring the uniformity of material distribution in the area covered by the guide trough 36.

[0041] Furthermore, if Figure 3 As shown, the fixed cross bar 71 is in an inverted U-shape, the open end of the fixed cross bar 71 is fixedly connected to the material guide trough 36 , and the horizontal section of the fixed cross bar 71 is located on the upper side of the material guide trough 36 .

[0042] In the above embodiment, the fixed cross bar 71 used in the present application to guide the guide trough 36 to swing is set in the above manner, which can increase the distance between the horizontal section of the fixed cross bar 71 and the guide trough 36, so that when the material flows along the guide trough 36, the impact of the fixed cross bar 71 on the material can be reduced.

[0043] The implementation principle of the embodiment is that when it is necessary to charge the electric furnace, the central charging pipe 4 in the furnace cover 1 can uniformly charge the material to the central area of the electric furnace, and the plurality of rotary distributors 3 arranged along the circumference of the furnace cover 1 can make the material guide groove 36 thereof realize horizontal rotation and vertical swing effect through the respective rotary motor 353 and the driving hydraulic cylinder 75, so as to ensure that the material guide groove 36 realizes uniform charging effect in the electric furnace, thereby ensuring the continuity and uniformity of the material distribution in the area corresponding to the rotary distributor 3. Even after the charging system of the application is charged in actual production, there are still some areas that need to be adjusted, but compared with the prior art, the workload of the workers will be much smaller, so that the charging system of the application can greatly reduce the labor intensity of the workers and improve the production efficiency of the equipment.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, and not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
