Description

Technical Field

[0001] This invention belongs to the field of metallurgical furnace flue technology, specifically relating to an anti-clogging metallurgical furnace flue. Background Technology

[0002] Metallurgical furnace flues serve as channels for the flue gas from metallurgical furnaces. Existing metallurgical furnace flue structures are mainly classified into refractory brick type, copper water jacket with refractory brick hybrid type, and jacket type. However, in water-cooled metallurgical furnace flues, the flue gas temperature is very high, and the flue gas contains a large amount of dust. Over time, dust accumulates on the inner wall of the flue, easily causing blockages. Since the flue is only one layer deep, if it becomes blocked during smelting, cleaning personnel must first enter the flue to clean it before smelting can continue, hindering smooth smelting operations and flue cleaning.

[0003] To address the issue of online cleaning of flue gas blockages, particularly during smelting operations, existing technologies propose a cleaning component installed within a cylindrical flue duct. This component includes a cleaning rod extending to the outside of the flue and cleaning rollers or blades mounted on the cleaning rod near the inner wall of the flue. A drive motor located outside the flue periodically rotates the cleaning rod around the axis of the main flue duct, thereby rotating the cleaning rollers or blades to perform circumferential cleaning of the flue's inner wall and prevent blockages. However, the main drawback is that the cleaning rollers and blades require a certain amount of time to thoroughly clean the flue's inner wall, hindering the rapid restoration of the flue's ventilation capacity. Furthermore, the cleaning component is exposed to high-temperature, high-dust flue gas. The circumferential rotation of the cleaning rods or blades within the entire radial cross-section of the flue disturbs and affects the flow of flue gas along the flue, impeding online operation and failing to meet the requirement for rapid online blockage prevention in metallurgical furnace flues.

[0004] Secondly, the cleaning components are exposed to high-temperature and high-dust flue gas channels. Due to the temperature of the flue gas and the corrosive effect of dust, the cleaning components are easily damaged and lose their cleaning ability. This will inevitably lead to the problem of excessive maintenance frequency, making it difficult to meet the requirement that the metallurgical furnace flue can be online for a long time to prevent blockage.

[0005] In addition, the existing metallurgical furnace flues are generally large rectangular cross-section structures. Replacing them with circular flues and corresponding cleaning components would be costly, which is not conducive to the transformation and promotion of existing metallurgical furnace flues. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the above-mentioned technical problems. The present invention provides an anti-clogging metallurgical furnace flue that can prevent metallurgical furnace flue blockage in a long-term, online and rapid manner, and facilitates the transformation and promotion of existing metallurgical furnace flues.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] A clog-resistant metallurgical furnace flue includes a flue body, an adsorption component, and a cleaning component. The adsorption component includes a fixing member and an annular adsorption element. The fixing member is close to the inner wall of the flue body and supports the adsorption element. The fixing member is connected to a first driving mechanism, which drives the adsorption element to rotate relative to the fixing member. The front side of the adsorption element can cover the inner wall of the flue body. The cleaning component is located between the back side of the adsorption element and the inner wall of the flue body, and is used to clean the back side of the adsorption element.

[0009] Furthermore, the top of the fixing member is provided with an upper baffle, and the bottom of the fixing member is provided with a lower baffle. Both the upper baffle and the lower baffle are fitted with the inner wall of the flue body. The adsorption component and the cleaning component are both located between the upper baffle and the lower baffle. The adsorption component is limited and fitted with the upper baffle and the lower baffle.

[0010] Furthermore, the adsorption component includes several movable plates that can slide and cooperate with the fixing component, with the first and last movable plates hinged to each other and adjacent movable plates hinged to each other.

[0011] Furthermore, a connecting rod is provided on one side of the movable plate, and connecting posts are provided at both ends of the connecting rod. At least two semicircular blocks are provided on the other side of the movable plate, and the connecting posts of the movable plate pass through the semicircular blocks of the adjacent movable plates.

[0012] Furthermore, the fixing member is provided with a first through hole, the adsorption member is sleeved on the outside of the fixing member, and the first driving mechanism includes a rotating cylinder located in the first through hole that can rotate, the rotating cylinder rollingly engaging with the inner wall of the adsorption member.

[0013] Furthermore, the inner wall of the flue body includes multiple facets in the circumferential direction, and the adsorption element includes multiple elements corresponding to each facet. The first driving mechanism is used to drive the adsorption elements of the multiple adsorption components to rotate synchronously.

[0014] Furthermore, the first driving mechanism includes a first servo motor, a transmission assembly, and several extension rods. The first servo motor and the transmission assembly are located outside the flue body. The first servo motor is used to drive several extension rods to rotate through the transmission assembly. The extension rods extend into the flue body and are provided with a rotating cylinder. The rotating cylinder rolls in cooperation with the inner wall of the adsorption element.

[0015] Furthermore, the transmission assembly includes a first gear and several second gears, the motor shaft of the first servo motor is connected to the first gear, the first gear meshes with several second gears, and the several second gears are respectively connected to several extension rods.

[0016] Furthermore, the cleaning assembly includes a first brush, a second brush, a first adjusting rod, and a second adjusting rod. The brush surfaces of the first brush and the second brush are in contact with the back of the adsorption component. One end of the first brush is connected to a second driving mechanism, which is used to drive the first brush to rotate around a vertical line of the brush surface. One end of the second brush is hinged to the other end of the first brush.

[0017] A support shaft and an elastic element are provided between the first adjusting rod and the first brush. The elastic element and the second adjusting rod are located on both sides of the support shaft, and the two ends of the second adjusting rod are respectively hinged to the middle of the first adjusting rod and the second brush.

[0018] Furthermore, the second drive mechanism includes a second servo motor located outside the flue body, the motor shaft of the second servo motor passing through the flue body and connected to the first brush.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) When high-temperature and high-dust flue gas passes through the inside of the flue body, and a large amount of dust adheres to the front of the adsorbent, the first drive mechanism drives the ring-shaped adsorbent to rotate relative to the fixed part. This can turn the clean back of the adsorbent to the front of the flue body covering the inner wall of the flue body, quickly and timely restore the flue's flue ventilation capacity before cleaning. At the same time, the front of the adsorbent with a large amount of dust is turned to the back and cleaned by the cleaning component. The cleaning component performs cleaning operations between the back of the adsorbent and the inner wall of the flue body, which can avoid circumferential rotation within the entire radial section of the flue and avoid disturbing the flue gas flow. This effectively solves the problem that the existing cleaning component is exposed in the high-temperature and high-dust flue gas channel and rotates circumferentially within the entire radial section of the flue, affecting the online operation of the flue and making it impossible to quickly and timely restore the flue's flue ventilation capacity. This meets the online cleaning needs of flue blockage during smelting.

[0021] (2) The cleaning component is located between the upper baffle and the lower baffle, which can further avoid the problem of the cleaning component being exposed to the flue gas and aggravating the corrosion. When the cleaning component is driven by the first servo motor to rotate around the first brush, it pulls or pushes the hinged first adjusting rod through centrifugal force and the elastic force of the spiral spring. Then, through the second adjusting rod, the second brush swings back and forth relative to the first brush. Through the combined motion of rotation and swing, the cleaning efficiency on the back of the adsorption component is further improved, which can meet the requirement that the metallurgical furnace flue can be online for a long time to prevent blockage.

[0022] (3) The first servo motor of the first drive mechanism drives several extension rods through the transmission assembly, and drives the corresponding rotating drums on the extension rods to rotate synchronously. The rotating drums and the adsorption components roll and rub against each other, driving the adsorption components to rotate relative to the fixed components, thereby realizing the synchronous rotation of the adsorption components of multiple adsorption components. By adding matching adsorption components and cleaning components, it can adapt to the existing metallurgical flue furnace with multiple facets such as rectangular cross sections, further reducing the transformation cost and facilitating its promotion and application.

Detailed Implementation

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "axial," "radial," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1:

[0044] To address the issue of flue blockage during online cleaning, particularly in smelting processes, where the cleaning components are exposed to high-temperature, high-dust flue gas channels and rotate circumferentially across the entire radial cross-section of the flue, hindering online flue operation and preventing the rapid and timely restoration of flue gas flow capacity, such as... Figure 1-9 The image shows a preferred embodiment of the anti-clogging metallurgical furnace flue of the present invention. The anti-clogging metallurgical furnace flue includes a flue body 1, an adsorption component 2, and a cleaning component 17. The adsorption component 2 includes a fixing member 201 and an annular adsorption member 202. The fixing member 201 is close to the inner wall of the flue body 1 and supports the adsorption member 202. The fixing member 201 is connected to a first driving mechanism 3. The first driving mechanism 3 is used to drive the adsorption member 202 to rotate relative to the fixing member 201. The front side 2021 of the adsorption member 202 can cover the inner wall of the flue body 1. The cleaning component 17 is located between the back side 2022 of the adsorption member 202 and the inner wall of the flue body 1. The cleaning component 17 is used to clean the back side 2022 of the adsorption member 202.

[0045] The working principle of the above-mentioned anti-clogging metallurgical furnace flue is as follows: Figure 3 As shown, when high-temperature, high-dust flue gas passes through the interior of the flue body 1, because the front surface 2021 of the adsorption component 202 covers the inner wall of the flue body 1, the dust in the flue gas adheres to the front surface 2021 of the adsorption component 202. After a period of use, as... Figure 5 As shown in Figure a, the front surface 2021 of the adsorption component 202 is covered with a large amount of dust. The first driving mechanism 3 activates the annular adsorption component 202, causing it to rotate relative to the fixed component 201. Figure 5 As shown in b, the clean back side 2022 of the adsorbent 202 is rotated to cover the inner wall of the flue body 1, becoming the new front side 2021 of the adsorbent 202. The front side 2021 of the adsorbent 202, which is covered with a lot of dust, is rotated back to become the new back side 2022 of the adsorbent 202. This allows the flue's ventilation capacity to be quickly and timely restored before cleaning. During ventilation, the dirty back side 2022 of the adsorbent 202 is cleaned by the cleaning component 17 to obtain a clean back side 2022 of the adsorbent 202, which can then be rotated again. The cleaning process is as follows: Figure 3As shown, since the cleaning component 17 performs cleaning operations between the back side 2022 of the adsorption component 202 and the inner wall of the flue body 1, it does not rotate circumferentially within the entire radial cross section of the flue, thereby avoiding affecting the online operation of the flue. This effectively solves the problem of online cleaning of flue blockage during smelting, allowing the flue to be cleaned without stopping production, thus improving convenience.

[0046] like Figure 3 As shown, the fixing member 201 is further provided with an upper baffle 203 at the top and a lower baffle 204 at the bottom. Both the upper baffle 203 and the lower baffle 204 are fitted with the inner wall of the flue body 1. The adsorption member 202 and the cleaning component 17 are located between the upper baffle 203 and the lower baffle 204, which can further isolate the cleaning component 17 from the flue gas, prevent the cleaning component 17 from being exposed to the flue gas and thus aggravating corrosion, further improve the durability of cleaning operation, and reduce the frequency of maintenance. The adsorption member 202 is limited by the upper baffle 203 and the lower baffle 204, which can position the adsorption member 202 on the fixing member 201, prevent the adsorption member 202 from moving up and down, and further improve the operational stability of the adsorption component 2.

[0047] Furthermore, the upper baffle 203 is connected to the flue body 1, so that the fixing member 201 is supported and fixed to the flue body 1. The lower baffle 204 is detachably connected to the fixing member 201 by bolts. During installation, the adsorption member 202 can be installed on the fixing member 201 first, and then the lower baffle 204 can be connected to the fixing member 201. After long-term use, the lower baffle 204 can be easily disassembled to remove the dust that falls off the back 2022 of the adsorption member 202 and accumulates on the lower baffle 204, thus facilitating maintenance.

[0048] like Figure 2-5 As shown, the adsorption component 202 further includes several movable plates 2023 that can slide and cooperate with the fixing component 201. The first and last movable plates 2023 are hinged to each other, and adjacent movable plates 2023 are hinged to each other. The outer surface of the movable plates 2023 plays the role of adsorbing dust in the flue gas. The movable plates 2023 have a certain degree of hardness and are also easy to rotate. The movable plates 2023 form a ring structure through hinges. Adjacent movable plates 2023 can be deflected relative to each other around the hinge position, so that the adsorption component 202 has a certain degree of flexibility. The two ends of the fixing component 201 can be arc-shaped, which facilitates the sliding cooperation between the fixing component 201 and the inner wall of the movable plate 2023 to keep the adsorption component 202 taut, thereby improving the operational stability of the adsorption assembly 2.

[0049] like Figure 4-5As shown, further, a connecting rod 2024 is provided on one side of the movable plate 2023, and connecting posts 2025 are provided at both ends of the connecting rod 2024. At least two semicircular blocks 2026 are provided on the other side of the movable plate 2023. The connecting posts 2025 of the movable plate 2023 pass through the semicircular blocks 2026 of adjacent movable plates 2023. The semicircular blocks 2026 can be located on the inner edge of the movable plate 2023. The hinge connection between adjacent movable plates 2023 is achieved by the connecting posts 2025 passing through the semicircular blocks 2026, making the adjacent movable plates 2023 more compact. Figure 5 As shown, the front 2021 and back 2022 of the annular adsorption component 202 are formed into a plane by several movable plates 2023, which further facilitates the adsorption and cleaning of dust.

[0050] Furthermore, the fixing member 201 is provided with a first through hole 2011, and the adsorption member 202 is sleeved on the outside of the fixing member 201 so that the fixing member 201 reliably supports the adsorption member 202. The first driving mechanism 3 includes a rotating cylinder 301 located in the first through hole 2011 that can rotate. The rotating cylinder 301 rolls with the inner wall of the adsorption member 202. The connecting column 2025 is parallel to the axis of the rotating cylinder 301. The first driving mechanism 3 can drive the adsorption member 202 to rotate around the fixing member 201 by the friction between the rotating cylinder 301 and the adsorption member 202.

[0051] like Figure 1-2 As shown, further, the inner wall of the flue body 1 includes multiple facets 101 in the circumferential direction, and the adsorption component 202 includes multiple components corresponding to each facet 101. The first driving mechanism 3 is used to drive the adsorption components 202 of the multiple adsorption components 2 to rotate synchronously, which can reduce the driving cost and facilitate the addition of adsorption components 2 and cleaning components 17 to existing metallurgical flue furnaces with multiple facets 101 such as rectangular cross sections, so as not to replace them with flues with circular cross sections, reduce the transformation cost, and facilitate promotion and application.

[0052] like Figure 3-6 As shown, the first driving mechanism 3 further includes a first servo motor 302, a transmission assembly 303, and several extension rods 304. The first servo motor 302 and the transmission assembly 303 are located outside the flue body 1. The first servo motor 302 is used to drive the several extension rods 304 to rotate through the transmission assembly 303. The extension rods 304 extend into the flue body 1 and are provided with rotating cylinders 301. The rotating cylinders 301 roll in cooperation with the inner wall of the adsorption member 202. The first servo motor 302 drives the several extension rods 304 through the transmission assembly 303, causing the corresponding rotating cylinders 301 on the extension rods 304 to rotate synchronously. The rotating cylinders 301 drive the adsorption member 202 to rotate relative to the fixed member 201, thereby realizing the synchronous rotation of the adsorption members 202 of multiple adsorption members 2. The structure is simple and the drive is reliable.

[0053] Furthermore, the fixing member 201 is provided with a second through hole 2012 communicating with the first through hole 2011. The extension rod 304 passes through the first through hole 2011 and is connected to the rotating cylinder 301 in the second through hole 2012. The rotating cylinder 301 protrudes from the fixing member 201 and cooperates with the adsorption member 202, which further compacts the structure and reduces the contact between the extension rod 304 and the flue gas, so as to improve the durability of the first drive mechanism 3.

[0054] Furthermore, the transmission assembly 303 includes a first gear 3031 and a plurality of second gears 3032. The motor shaft of the first servo motor 302 is connected to the first gear 3031. The first gear 3031 meshes with the plurality of second gears 3032. The plurality of second gears 3032 are respectively connected to a plurality of extension rods 304. The first servo motor 302 drives the first gear 3031 to rotate, which transmits the power to the meshing plurality of second gears 3032, thereby driving the corresponding extension rods 304 connected to the second gears 3032 to rotate, thus achieving synchronous transmission. The structure is simple and easy to apply.

[0055] Furthermore, the transmission assembly 303 is provided with a cover, the first servo motor 302 is mounted on the top of the cover, the motor shaft of the first servo motor 302 is connected to a first transmission rod 3033 passing through the cover, a rotating block 3034 is sleeved on the surface of the first transmission rod 3033, and the rotating block 3034 is coaxially connected to the first gear 3031, which further facilitates the installation of the first servo motor 302 and the protection of the transmission assembly 303.

[0056] like Figure 7-9 As shown, the cleaning component 17 further includes a first brush 1701, a second brush 1703, a first adjusting rod 1707, and a second adjusting rod 1705. The brush surfaces of the first brush 1701 and the second brush 1703 are in contact with the back surface 2022 of the adsorption component 202. One end of the first brush 1701 is connected to a second driving mechanism, which is used to drive the first brush 1701 to rotate around the vertical line of the brush surface. One end of the second brush 1703 is hinged to the other end of the first brush 1701.

[0057] A support shaft 1708 and an elastic element 1709 are provided between the first adjusting rod 1707 and the first brush 1701. The elastic element 1709 and the second adjusting rod 1705 are respectively located on both sides of the support shaft 1708. The two ends of the second adjusting rod 1705 are respectively hinged to the middle of the first adjusting rod 1707 and the second brush 1703.

[0058] Furthermore, the first brush 1701 is provided with a third through hole 1710 and a first hinge joint 1702, the second brush 1703 is provided with a first recess 1711 and a second recess 1712, the first recess 1711 is hinged to the first hinge joint 1702, one end of the first adjusting rod 1707 extends into the third through hole 1710, both ends of the support shaft 1708 are provided in the upper part of the third through hole 1710, the elastic element 1709 is provided in the lower part of the third through hole 1710, and both ends of the second adjusting rod 1705 are provided with a second hinge joint 1706 and a third hinge joint 1704 respectively, the second hinge joint 1706 is hinged to the other end of the first adjusting rod 1707 extending out of the third through hole 1710, and the third hinge joint 1704 is hinged to the second recess 1712 in the middle of the second brush 1703, thereby facilitating the compact installation of the cleaning assembly 17.

[0059] Furthermore, both the third through hole 1710 and the first adjusting rod 1707 are provided with positioning holes 1713. The elastic element 1709 is a helical spring, with both ends of the helical spring respectively set in the positioning holes 1713 of the third through hole 1710 and the first adjusting rod 1707. The structure is simple and easy to install and apply.

[0060] Furthermore, the second drive mechanism includes a second servo motor 14 located outside the flue body 1, the motor shaft of the second servo motor 14 passing through the flue body 1 and connected to the first brush 1701.

[0061] Furthermore, the motor shaft of the second servo motor 14 is connected to a coaxial second transmission rod 16, which connects to the first brush 1701, further facilitating the connection and installation of the second servo motor 14.

[0062] The working principle of the cleaning component 17 mentioned above is as follows:

[0063] like Figure 9 As shown in Figure a, in the initial state, the spring is in its natural state, as... Figure 9 a to Figure 9 b to Figure 9 c to Figure 9 As shown in diagram d, the cleaning assembly 17 is driven by the first servo motor 302 to rotate around the first brush 1701. During rotation, under the action of centrifugal force, the hinge position between the second brush 1703 and the first brush 1701 deflects outward, pulling the hinged second adjusting rod 1705. The second adjusting rod 1705 deflects around the hinge position with the second brush 1703 and pulls the first adjusting rod 1707, causing the first adjusting rod 1707 and the second adjusting rod 1705 to deflect relative to their hinge position. At the same time, the first adjusting rod 1707 deflects outward around the support shaft 1708, compressing the helical spring. Figure 9 a state change to Figure 9 b state.

[0064] When the elastic restoring force of the compressed helical spring is greater than the centrifugal force, the helical spring pushes the first adjusting rod 1707, which deflects inward around the support shaft 1708, pulling the second adjusting rod 1705. This, in turn, through the hinge, pulls the second brush 1703 inward relative to the hinge position of the first brush 1701, causing the helical spring to extend. Figure 9 State b changes to Figure 9 c state.

[0065] When the centrifugal force exceeds the elastic restoring force, the second brush 1703 is driven to deflect outward relative to the first brush 1701 again, as... Figure 9 c state changes to Figure 9 In state d, this process is repeated, causing the second brush 1703 to swing back and forth relative to the first brush 1701. The brush surfaces of the rotating first brush 1701 and the rotating second brush 1703 that swings relative to the first brush 1701 clean the back side 2022 of the dirty adsorption component 202, further improving cleaning efficiency. Example 2:

[0066] like Figure 10-11 As shown, this is a preferred embodiment of the anti-clogging metallurgical furnace flue of the present invention. The difference from Embodiment 1 is that the flue body 1 has a circular cross-section, and the fixing member 201 has a C-shaped structure. The cleaning component 17 includes a first brush 1701, which is connected to a third driving mechanism. The third driving mechanism includes a hollow rotating platform 7 installed on the flue body 1. A connecting rod 8 is provided between the disk 701 of the hollow rotating platform 7 and the first brush 1701. The hollow rotating platform 7 uses a worm gear principle to drive the disk 701 to rotate around the axial direction of the flue body 1, driving the first brush 1701 to clean the back 2022 of the adsorption member 202 between the back 2022 and the inner wall of the flue body 1. This further facilitates the application of the circular cross-section metallurgical furnace flue. Moreover, through the driving application of the hollow rotating platform 7, the cleaning component 17 will not rotate circumferentially within the entire radial cross-section of the flue, further avoiding interference with the operation of the flue when the cleaning component 17 cleans the adsorption member 202. Example 3:

[0067] like Figure 12 As shown, this is a preferred embodiment of the anti-clogging metallurgical furnace flue of the present invention.
