Description

Technical Field

[0001] This utility model relates to the field of electric arc furnace technology, specifically to an electric arc furnace telescopic material distribution device. Background Technology

[0002] A submerged arc furnace, also known as an electric arc furnace or resistance furnace, is an important industrial electric furnace in the metallurgical industry. It is mainly used for reducing and smelting raw materials such as ores, carbonaceous reducing agents and solvents, and can produce ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and ferrosilicon-manganese alloy. It is also an important production equipment for chemical raw materials such as calcium carbide.

[0003] Chinese Patent CN215113857U discloses an automated submerged arc furnace feeding device, comprising a housing. First telescopic mechanisms are fixedly installed on both the left and right sides of the housing, and second telescopic mechanisms symmetrically distributed on the left and right sides are fixedly installed on the bottom of the housing. A first bearing is fixedly installed at the bottom of the second telescopic mechanism, and a rotating shaft is fixedly installed inside the first bearing. Pulleys are fixedly installed at both ends of the rotating shaft. An anti-reverse mechanism is fixedly installed at the bottom of the first telescopic mechanism, and an mounting shaft is fixedly installed on the front of the first bearing. When the housing is loaded with goods, the weight of the housing increases, causing the anti-reverse mechanism to move upwards via a first rack and pinion, thus activating the anti-reverse mechanism. When the goods are unloaded from the housing, the weight of the housing decreases, causing the anti-reverse mechanism to move downwards via the first rack and pinion, thus deactivating the anti-reverse mechanism, achieving automated control.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: the above solutions use the first rack and gear to move the anti-reverse mechanism upward. When the goods in the box are unloaded, the weight of the box decreases, and the first rack and gear move the anti-reverse mechanism downward to achieve automated control. However, transporting materials through the box is inefficient, and the limited volume of the box leads to the need to reload and transport materials again, which seriously affects the material transport. In addition, it is not possible to distribute the material, resulting in the material not being evenly distributed inside the electric arc furnace. Therefore, we provide a telescopic material distribution device for an electric arc furnace. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic material distribution device for a submerged arc furnace, which solves the technical problems of low efficiency in transporting materials through a box, limited box volume, which requires reloading and re-transporting materials, thus seriously affecting material transportation, and the inability to distribute materials, resulting in uneven distribution of materials inside the submerged arc furnace.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A telescopic feeding device for a submerged arc furnace includes a submerged arc furnace body; a floor is provided on one side of the submerged arc furnace body; a feeding port is opened inside the submerged arc furnace body; a feeding rack is provided on one side of the submerged arc furnace body; multiple sets of universal wheels are installed at the bottom of the feeding rack; a discharge pipe is fixedly connected to the top of the feeding rack; a hopper is fixedly connected to the top of the discharge pipe; and an adjustment unit is provided on one side of the feeding rack.

[0008] As a further embodiment of this utility model: the adjustment unit includes a motor; a rotating plate is fixedly connected to the output end of the motor; an adjustment guide plate is fixedly connected to the top end of the rotating plate; the adjustment guide plate is located on one side of the discharge pipe.

[0009] As a further embodiment of this utility model: a guide rail is provided on one side of the electric arc furnace body; a slider is slidably connected to the inner side wall of the guide rail; the slider is located below the feeding rack.

[0010] As a further embodiment of this utility model: a rocker plate is rotatably connected inside the discharge pipe; an electric push rod is fixed to the inner wall of the discharge pipe, and the electric push rod is located at one end of the rocker plate; a cloth bag is connected to the side end of the rocker plate.

[0011] As a further embodiment of this utility model: a second electric push rod is fixedly connected inside the feeding rack; a positioning block is fixedly connected to the bottom end of the second electric push rod, and the positioning block corresponds to the slider.

[0012] As a further embodiment of this utility model: an electric slide rail is provided below the adjusting guide plate; a motor is slidably connected to the top of the electric slide rail.

[0013] The beneficial effects of this utility model are as follows: The universal wheels can push the feeding rack to move, aligning the discharge pipe with the inlet. The material can enter the interior of the discharge pipe through the hopper, and then be discharged to the inlet through the discharge pipe. The material can fall down the discharge pipe into the interior of the adjusting guide plate, and then enter the interior of the submerged arc furnace body through the adjusting guide plate. When it is necessary to distribute the material, the motor drives the rotating plate to rotate, and the rotation of the rotating plate causes the adjusting guide plate to rotate as well. The rotation of the adjusting guide plate can control the guiding position of the material, thereby facilitating the distribution of the material and preventing the material from piling up. It also makes it easy to adjust and distribute the material. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a telescopic feeding device for a submerged arc furnace includes a submerged arc furnace body 1; a floor 2 is provided on one side of the submerged arc furnace body 1; a feed inlet 18 is provided inside the submerged arc furnace body 1; a feeding rack 3 is provided on one side of the submerged arc furnace body 1; multiple sets of universal wheels 15 are installed at the bottom end of the feeding rack 3; a discharge pipe 7 is fixedly connected to the top end of the feeding rack 3; a hopper 6 is fixedly connected to the top end of the discharge pipe 7; and an adjustment unit is provided on one side of the feeding rack 3.

[0021] During operation, the staff moves the feeding rack 3 to one side of the electric arc furnace body 1. The feeding rack 3 can be moved by the casters 15 so that the discharge pipe 7 is aligned with the inlet 18. The material can enter the interior of the discharge pipe 7 through the hopper 6 and then be discharged to the inlet 18 through the discharge pipe 7.

[0022] The adjustment unit includes a motor 10; a rotating plate 9 is fixedly connected to the output end of the motor 10; an adjustment guide plate 8 is fixedly connected to the top end of the rotating plate 9; the adjustment guide plate 8 is located on one side of the discharge pipe 7.

[0023] The material can fall through the discharge pipe 7 into the interior of the adjusting guide plate 8, and then enter the interior of the submerged arc furnace body 1 through the adjusting guide plate 8. When the material needs to be distributed, the rotating plate 9 is rotated by the motor 10. The rotation of the rotating plate 9 causes the adjusting guide plate 8 to rotate as well. The rotation of the adjusting guide plate 8 can control the material guiding position, thereby facilitating the distribution of the material and preventing the material from piling up. It also makes it easy to adjust the distribution of the material.

[0024] A guide rail 4 is provided on one side of the electric arc furnace body 1; a slider 5 is slidably connected to the inner side wall of the guide rail 4; the slider 5 is located below the feeding rack 3.

[0025] Before starting work, move the feeding rack 3 onto the slider 5. The slider 5 can be rotated via the guide rail 4. The rotation of the slider 5 can adjust the position of the feeding rack 3, thereby adjusting the position of the discharge pipe 7, which can be used to distribute the material and avoid material accumulation.

[0026] The discharge pipe 7 is rotatably connected to a rocker plate 14; an electric push rod 13 is fixed to the inner side wall of the discharge pipe 7, and the electric push rod 13 is located at one end of the rocker plate 14; a cloth bag 12 is connected to the side end of the rocker plate 14.

[0027] The material enters the discharge pipe 7 through the hopper 6 to prevent the material from getting stuck inside the discharge pipe 7. The first electric push rod 13 can make the seesaw plate 14 rotate, which can push the blocked material downward. The side end of the seesaw plate 14 is connected to the cloth bag 12 to prevent the material from falling to the bottom of the seesaw plate 14.

[0028] The feeding rack 3 is internally fixed with a second electric push rod 16; the bottom end of the second electric push rod 16 is fixed with a positioning block 17, which corresponds to the slider 5.

[0029] When the material is conveyed through the discharge pipe 7, it will be bumped, causing the feeding rack 3 to shake. After the feeding rack 3 moves onto the slider 5, the positioning block 17 is inserted into the inside of the slider 5 by the second electric push rod 16. The positioning block 17 then limits the position of the feeding rack 3 on the slider 5, preventing the feeding rack 3 from shaking during operation.

[0030] An electric slide rail 11 is provided below the adjusting guide plate 8; a motor 10 is slidably connected to the top of the electric slide rail 11.

[0031] The position of the adjusting guide plate 8 can be adjusted according to the needs. The motor 10 can be slid through the electric slide rail 11. The sliding of the motor 10 causes the adjusting guide plate 8 to slide together. The sliding extension and retraction of the adjusting guide plate 8 can adjust the discharge position, which can be adjusted according to the working requirements of the electric arc furnace body 1.

[0032] The working principle of this utility model is as follows: During operation, the operator moves the feeding rack 3 to one side of the electric arc furnace body 1. The universal wheels 15 can be used to move the feeding rack 3, aligning the discharge pipe 7 with the inlet 18. Material can enter the discharge pipe 7 through the hopper 6 and then be discharged to the inlet 18. The material can fall along the discharge pipe 7 into the adjusting guide plate 8 and then into the electric arc furnace body 1. When material distribution is required, the motor 10 rotates the rotating plate 9, which in turn rotates the adjusting guide plate 8. The rotation of the adjusting guide plate 8 controls the material's guiding position, facilitating material distribution and preventing material accumulation. The position of the adjusting guide plate 8 can be adjusted as needed. The electric slide rail 11 allows the motor 10 to slide, which in turn causes the adjusting guide plate 8 to slide. The sliding and extending of the adjusting guide plate 8 adjusts the discharge position. The adjustment can be made according to the working requirements of the electric arc furnace body 1. The material enters the discharge pipe 7 through the hopper 6 to avoid material blockage inside the discharge pipe 7. The first electric push rod 13 can rotate the tilting plate 14, which can push the blocked material downward. The side end of the tilting plate 14 is connected to the cloth bag 12 to prevent the material from falling to the bottom of the tilting plate 14. Before operation, the feeding rack 3 is moved onto the slider 5. The slider 5 can be rotated through the guide rail 4. The rotation of the slider 5 can adjust the position of the feeding rack 3, thereby adjusting the position of the discharge pipe 7, which can be used to distribute the material and avoid material accumulation. When the material is conveyed through the discharge pipe 7, it will bump, causing the feeding rack 3 to shake. After the feeding rack 3 moves onto the slider 5, the second electric push rod 16 inserts the positioning block 17 into the inside of the slider 5, thereby limiting the position of the feeding rack 3 on the slider 5 through the positioning block 17, and preventing the position of the feeding rack 3 from shaking during operation.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
