Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices for submerged arc furnaces, and more specifically, to an energy-saving semi-enclosed silicon-manganese alloy submerged arc furnace dust removal device. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials and chemical raw materials such as calcium carbide in the metallurgical industry. Submerged arc furnace will produce a lot of flue gas during operation, which contains pollutants such as dust, harmful gases and particulate matter, which have an impact on the environment and human health. In order to prevent the internal gas from diffusing, the dust removal device of the submerged arc furnace needs to be opened regularly for internal maintenance. Therefore, it is generally semi-closed. In order to protect the environment and save energy, the submerged arc furnace is dusted at the same time, which has an energy-saving effect in the process of dust removal of the submerged arc furnace.

[0032] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification.

[0033] like Figures 1 to 8As shown, an energy-saving semi-enclosed silicon-manganese alloy ore furnace dust removal device described in an embodiment of the present invention includes a base 1, a support seat 12 is fixedly installed on the top of the base 1, a first circular tube 11 is fixedly installed on the top of the support seat 12, the bottom center of the first circular tube 11 is connected to the inside of the base 1, a second circular tube 13 is fixedly installed on the outer wall of the first circular tube 11, an upper riser 14 is fixedly installed on the top of the second circular tube 13, a discharge pipe seat 15 is fixedly installed on the top of the upper riser 14, a filter device 2 is arranged inside the first circular tube 11, the filter device 2 is used for preliminary filtering of dust, a bag dust removal device 16 is arranged inside the upper end of the discharge pipe seat 15, and the filter device 2 includes two support dust rings 211 fixedly installed on the inner wall of the first circular tube 11, and there is a distance between the two support dust rings 211. , the side walls of the two supporting dust rings 211 are rotatably mounted with filter plates 21, and the ends of the supporting dust rings 211 are fixedly mounted with cleaning devices 3, and the cleaning devices 3 are used to clean the holes on the filter plates 21, and the lower ends of the filter plates 21 are provided with conveying devices 4, and the conveying devices 4 are used to collect and transport the dust after being cleaned by the cleaning devices 3, and the cleaning devices 3 include: a cleaning bin 31 fixedly mounted on the inner wall of the upper end of the first circular tube 11; a cleaning cylinder 32 rotatably mounted inside the cleaning bin 31; a first lifting rod 33 slidably mounted on the inner wall of the cleaning cylinder 32, and a plurality of conical cleaning assemblies 35 are fixedly mounted on the bottom end of the first lifting rod 33, and the lifting of the first lifting rod 33 drives the conical cleaning assemblies 35 to extend and retract to the inside of the filter plate 21 to clean the mesh of the filter plate 21; a first gear 34 fixedly mounted on the outer wall of the end of the cleaning cylinder 32.

[0034] It should be noted that, considering that when removing dust from the ore-fired furnace, the prior art generally performs preliminary treatment and cooling of the dust first, and then filters the fine dust through bag dust removal to prevent the bag from catching fire and burning due to excessive temperature when the bag dust removal is used later. When performing preliminary dust removal, a filter screen is generally used, and the filter screen plate (such as Figure 2 The filter plate 21 in the figure, the filter screen and the filter screen plate hereinafter refer to Figure 2 When filtering with a filter screen plate, there may be a large amount of semi-molten silicon-manganese alloy rock in the solid of the ore-fired furnace, which may clog the filter screen holes when passing through the filter screen plate, and cool and adhere to the holes of the filter screen plate, resulting in poor initial filtering effect. In order to solve this problem, the following improvements are made:

[0035] First, the dust mixture generated by the electric arc furnace is passed into the interior of the first circular tube 11 through the second circular tube 13, and the second circular tube 13 is located below the filter device 2. The dust mixture passed in has a large amount of heat. Since heat has a tendency to rise, it will rise upward when passing into the interior of the first circular tube 11, and the dust mixture will pass through the filter plate 21 inside the filter device 2. When passing through the filter plate 21, solids larger than the mesh diameter of the filter plate 21 will be filtered out by the filter plate 21, and thus will remain in the lower part of the filter plate 21. As the heat drops, the solids will fall to the bottom of the first circular tube 11, and enter the interior of the base 1 through the pipe set at the bottom of the first circular tube 11, and there will be a small difference in the mesh diameter with the filter plate 21. Solids will get stuck inside the filter plate 21, causing the filter plate 21 to be blocked. A conveying device 4 is provided at the lower end of the filter plate 21. The position of the conveying device 4 corresponds to the position of the cleaning device 3. At this time, a row of mesh holes on the filter plate 21 is isolated through the cleaning bin 31 provided on the filter plate 21. At this time, a motor can be provided inside the first circular tube 11 at a position at the end of the cleaning cylinder 32 away from the center of the filter plate 21. The cleaning cylinder 32 is driven by the motor to rotate, and then a telescopic rod is provided inside the cleaning cylinder 32. The output end of the telescopic rod is connected to the top of the first lifting rod 33, and the transmission rod 22 is fixedly installed on the top of the center of the filter plate 21. The top of the transmission rod 22 is fixedly installed with a top isolation tube 24. The outer wall is fixedly provided with a jet elbow 25. After the dust mixture passes through the filter plate 21, it continues to rise and is ejected through the jet elbow 25. The jet elbow 25 has a certain curvature. Therefore, under the action of the hot air, the top isolation pipe 24 is driven to rotate and is ejected from the mouth of the jet elbow 25. The filter plate 21 can be driven to rotate without using a motor, thereby achieving energy saving. A transmission rod 22 is provided at the central bottom end of the top isolation pipe 24. A sensor can be provided at the outer wall edge of the filter plate 21. When the sensor detects that a row of mesh holes on the filter plate 21 passes through the central position of the cleaning chamber 31, the telescopic rod and the motor are started. The motor drives the cleaning cylinder 32 to rotate with the mesh holes on the filter plate 21, and the telescopic rod can be quickly popped out at the moment of starting, thereby bringing The first lifting rod 33 is driven to move toward the direction close to the filter plate 21, and the first lifting rod 33 drives the cone cleaning assembly 35 to move toward the direction close to the filter plate 21, thereby driving the cone cleaning assembly 35 to rush out of the mesh on the filter plate 21. If the mesh inside the filter plate 21 is blocked, the blockage can be removed, thereby ensuring the cleaning effect of the filter plate 21, and the blocked object is transported out of the first circular tube 11 through the conveying device 4. This device can continuously clean the filter plate 21 without taking out the filter plate 21, thereby preventing the filter plate 21 from having a weakened cleaning ability due to blockage, and preventing the filter plate 21 from being damaged by high temperature generated inside the first circular tube 11. When the temperature drops, the filtered solids fall into the inside of the base 1,After that, the base 1 can be opened to remove the solids, and a bag dust collector 16 is provided at the upper end of the top isolation pipe 24. The bag dust collector 16 can filter fine dust, and the bag dust collector 16 is provided with circulating air inside. Before the dust enters the bag dust collector 16, the air flowing inside the bag dust collector 16 is first cooled down, and then enters the bag provided inside the bag dust collector 16 for filtering. The filtered gas is denitrated and desulfurized through the discharge pipe seat 15, and can be discharged into the air, thereby reducing the problem of air pollution caused by gas emissions in the ore-fired furnace. The discharge pipe seat 15 is detachable, so after the bag dust collector 16 has been filtered for many times, the discharge pipe seat 15 can be opened, and the dust in the bag inside the bag dust collector 16 can be cleaned, and the cleaning work is completed.

[0036] like Figures 1 to 4 As shown, the filtering device 2 also includes: a transmission rod 22 fixedly mounted on the top center of the filter plate 21; a top isolation tube 24 fixedly mounted on the top of the transmission rod 22, a plurality of jet bends 25 fixedly mounted on the outer wall of the top isolation tube 24, the jet bends 25 are semicircular, the top isolation tube 24 is an inverted cylindrical cup, the jet bends 25 are arranged in a circle with the top isolation tube 24 as the center, the inside of the jet bends 25 is hollow, and the jet bends 25 are connected to the inside of the top isolation tube 24; a bottom boss tube 23 fixedly mounted on the bottom end of the top isolation tube 24, the lower end of the bottom boss tube 23 is in contact with the inner wall of the upper riser 14; top teeth 212 and bottom teeth 213 fixedly mounted on the top and bottom ends of the filter plate 21, the top teeth 212 are connected to the cleaning device 3, and the bottom teeth 213 are connected to the conveying device 4.

[0037] It should be noted that, considering that the dust gas rises during use and can drive the filter plate 21 to rotate, a top tooth 212 and a bottom tooth 213 are provided on the outer wall edge of the filter plate 21, and the top tooth 212 is connected to the cleaning device 3, and the bottom tooth 213 is connected to the conveying device 4. Therefore, during use, the hot gas is ejected through the top isolation tube 24 through the jet elbow 25, thereby driving the jet elbow 25 to rotate, and the bottom boss tube 23 is a hollow cone, so that during use, the gas can completely enter the interior of the top isolation tube 24, and the outer diameter of the lower end of the bottom boss tube 23 is the same as the first The inner diameters of the circular tubes 11 are the same, so that the dust gas will not pass through the top isolation tube 24 and directly enter the interior of the bag dust removal device 16. A first gear 34 is provided on the outer wall of the end of the cleaning cylinder 32. The first gear 34 is engaged with the top teeth 212. Therefore, the cleaning cylinder 32 is driven to rotate during the rotation of the filter plate 21. The filter plate 21 drives the cleaning cylinder 32 to rotate one circle and can be aligned with the next row of meshes, thereby completing the effect of automatic alignment of the cone cleaning component 35 and the meshes on the filter plate 21. There is no need to set sensors and motors inside the first circular tube 11 to clean the meshes of the filter plate 21.

[0038] like Figures 4 to 7 As shown, the cleaning device 3 also includes: a moving groove 312 arranged on the side wall of the cleaning cylinder 32, a first limit block 311 is arranged inside the center of the moving groove 312, and the side wall of the first limit block 311 is fixedly installed on the inner wall of the first circular tube 11; a first fixed plate 321 fixedly installed at the end of the cleaning cylinder 32; a first spring 322 fixedly installed at the bottom end of the first fixed plate 321, and the bottom end of the first spring 322 is fixedly installed on the top end of the first lifting rod 33; a first protrusion 331 fixedly installed at the end of the first lifting rod 33, and the first protrusion 331 slides inside the moving groove 312.

[0039] It should be noted that, considering that the cone cleaning assembly 35 can automatically pop out according to the rotation state of the cleaning cylinder 32 during use, a first limit block 311 is provided on the inner wall of the first circular tube 11, a first fixed plate 321 and a first spring 322 are provided at the end of the cleaning cylinder 32, and a first protrusion 331 is provided at the end of the first lifting rod 33, so that the first protrusion 331 slides inside the moving groove 312, so that during the rotation of the cleaning cylinder 32, the cone cleaning assembly 35 can follow the rotation of the filter plate 21 and shrink toward the inside of the cleaning chamber 31. When the cleaning cylinder 32 rotates one circle, the cone cleaning assembly 35 is completely retracted to the inside of the cleaning cylinder 32, and the retraction and extension of the cone cleaning assembly 35 can be completed without the telescopic rod.

[0040] like Figures 6 to 8As shown, a cavity is arranged inside the cleaning cylinder 32 to accommodate the conical cleaning assembly 35, and a limited motion groove 323 is arranged inside the cavity accommodating the conical cleaning assembly 35. The limited motion groove 323 is connected to the conical cleaning assembly 35, so that the conical cleaning assembly 35 is driven to rotate when the conical cleaning assembly 35 is extended or retracted.

[0041] It should be noted that, considering that when the cone cleaning assembly 35 cleans the holes on the filter plate 21, although direct impact can remove the blockage, the blockage may adhere to the outer wall of the cone cleaning assembly 35 as a whole, a limited motion groove 323 is provided in the groove accommodating the cone cleaning assembly 35 on the cleaning cylinder 32, and a plurality of protrusions are provided on the outer wall of the cone cleaning assembly 35, so that the cone cleaning assembly 35 as a whole slides inside the limited motion groove 323 during the extension process, driving the cone cleaning assembly 35 to rotate as a whole, thereby preventing the blockage from adhering to the outer wall of the cone cleaning assembly 35 as a whole.

[0042] like Figures 6 to 8 As shown, the cone cleaning assembly 35 includes: a top support plate 351 fixedly mounted on the bottom end of the first lifting rod 33; a middle support rod 357 fixedly mounted on the bottom end of the top support plate 351; a first protrusion 352 fixedly mounted on the outer wall of the middle support rod 357; a second protrusion 353 fixedly mounted on the end of the first protrusion 352; a first rotating rod 354 rotatably mounted inside the second protrusion 353, a torsion spring is provided at the connection portion between the second protrusion 353 and the first rotating rod 354, so that the first rotating rod 354 is horizontally downward in a normal state, and a cleaning block 355 is fixedly mounted on the end of the first rotating rod 354; and a bottom conical block 356 fixedly mounted on the bottom end of the middle support rod 357.

[0043] It should be noted that, when the conical cleaning assembly 35 is extended, in order to enable the conical cleaning assembly 35 to remove the semi-dissolved solids adhering to the holes of the filter plate 21, the outer wall of the middle support rod 357 is provided with a first protrusion 352 and a second protrusion 353 as well as a first rotating rod 354 and a cleaning block 355. When the conical cleaning assembly 35 is rotated, the cleaning block 355 can be driven to extend, so that the cleaning block 355 and the first rotating rod 354 rotate 90° with the second protrusion 353 as the center, so that the cleaning block 355 and the first rotating rod 354 and the first protrusion 352 are in the same horizontal plane, thereby cleaning the solids adhering to the holes of the filter plate 21, and the second protrusion 353 and the first rotating rod 354 are provided with a torsion spring so that in a normal state, the direction of the cleaning block 355 is kept horizontal with the bottom conical block 356.

[0044] like Figures 1 to 4As shown, the conveying device 4 includes: a collecting bin 41 fixedly mounted on the inner wall of the first circular tube 11 and located directly below the cleaning bin 31, the top of the collecting bin 41 being in an open state; a conveying reel 42 rotatably mounted inside the lower end of the collecting bin 41; a second gear 43 fixedly mounted on the end of the conveying reel 42; a third gear 44 rotatably mounted on the side wall of the collecting bin 41, the third gear 44 meshing with the second gear 43, an isolation plate 46 fixedly mounted inside the collecting bin 41 and located on the side wall of the second gear 43, the isolation plate 46 being used to separate the second gear 43 from the conveying reel 42; a conveying pipe 45 fixedly mounted at the bottom end of the collecting bin 41, the conveying pipe 45 passing through the interior of the first circular tube 11.

[0045] It should be noted that, considering the need to clear the blockage punched out from the end of the bottom conical block 356 out of the interior of the first circular tube 11, a collecting bin 41 and a transport reel 42 are provided directly below the cleaning bin 31. When the filter plate 21 drives the bottom teeth 213 to rotate, the third gear 44 and the second gear 43 can be driven to rotate. The rotation of the third gear 44 and the second gear 43 drives the transport reel 42 to rotate, and the blockage is transported in the direction close to the second gear 43. The bottom end of the collecting bin 41 is provided with an opening connected to the transport pipe 45, so that the blockage is transported out of the interior of the collecting bin 41 from the transport pipe 45. The interior of the collecting bin 41 is provided with an isolation plate 46, so as to facilitate the separation of the third gear 44 and the second gear 43 from the blockage, thereby completing the work of clearing the blockage from the interior of the collecting bin 41.

[0046] like Figure 3 to Figure 4 As shown, the diameter of the top support plate 351 is smaller than the diameter of the hole on the filter plate 21 , and the distance between the cleaning block 355 and the top support plate 351 when extended is smaller than the diameter of the hole on the filter plate 21 .

[0047] It should be noted that the diameter of the top support plate 351 is smaller than the diameter of the hole on the filter plate 21, so that the top support plate 351 can drive the bottom conical block 356 to fully extend into the hole on the filter plate 21. When the cleaning block 355 is extended, the distance from the top support plate 351 is smaller than the diameter of the hole on the filter plate 21, preventing the cleaning block 355 from being stuck in the hole on the filter plate 21 when the cleaning cylinder 32 rotates.

[0048] like Figure 2 As shown, the distance between the end of the jet elbow 25 and the center of the top isolation pipe 24 is smaller than the inner diameter of the upper riser 14 .

[0049] It should be noted that the distance between the end of the jet bend 25 and the center of the top isolation pipe 24 is smaller than the inner diameter of the upper riser 14, so that when the top isolation pipe 24 drives the jet bend 25 to rotate, the gas is ejected, and the upper riser 14 will not block and hinder the jet bend 25 from ejecting.
