Description

Technical Field

[0001] This invention belongs to the technical field of pipeline cleaning equipment, specifically relating to a cleaning device for the flue of a sintering machine batching and dust removal system. Background Technology

[0002] The above-mentioned sintering machine batching process is the sintering mixing process in the steel industry, specifically involving the mixing and granulation of raw materials. More specifically, iron ore powder, fluxes such as limestone, fuels such as coke powder, and recycled ore are mixed in a specific ratio, with the addition of an appropriate amount of water. The mixture is then tumbled and kneaded in a mixer, such as a cylindrical mixer, to form uniformly sized particles (also called "small balls" or "agglomerates"), thereby improving the permeability of the material layer. During the mixing process, water is sprayed or steam is introduced to promote granulation and to raise the material temperature above the dew point, preventing moisture condensation during subsequent sintering and thus reducing the permeability of the material layer. The mixed material is then conveyed to the sintering machine via a conveyor belt, and after distribution, it is ignited and sintered.

[0003] As can be seen from the above, the sintered ore contains lime, and because the lime becomes extremely sticky after being heated in the mixer, the dust from the inlet and outlet of the mixer is mixed with lime and mineral powder during the process of being drawn into the dust removal duct by the dust removal device such as the dust removal fan. It is also easy for the dust to harden on the inner wall of the duct. If it is not cleaned properly or not cleaned effectively, it will eventually cause the duct to be completely blocked.

[0004] Regularly or irregularly removing solid waste or scale from the flue while the machine is shut down is a way to avoid flue blockage. However, not only is the cleaning effect difficult to guarantee, but the operation is also labor-intensive and inefficient. Furthermore, the shutdown will affect the production capacity. Therefore, this passive cleaning method has caused considerable difficulties for the industry.

[0005] Therefore, it is of positive significance to explore devices that can effectively prevent the blockage of flue gas ducts, which serve as branch pipes in the sintering and mixing process of the steel industry. The technical solution to be introduced below was developed in this context. Summary of the Invention

[0006] The objective of this invention is to provide a cleaning device for the flue of a sintering machine batching and dust removal system that helps to eliminate manual cleaning, thereby reducing the workload of online operators and ensuring good cleaning results; facilitates automatic cleaning without stopping the machine, thus avoiding affecting the sintering efficiency; integrates softening, scraping, and melting into one to demonstrate an excellent multi-pronged synergistic cleaning mechanism and ideal environmental protection; and has a simplified overall structure for easy installation and maintenance, while also demonstrating good usability and low cost.

[0007] The present invention achieves its objective by providing a cleaning device for the flue of a sintering machine batching and dust removal system. The flue includes a main flue, branch flues, and a dust collection hood. The main flue and branch flues are supported on a flue support during use. The end of the branch flue facing the main flue is orthogonally connected to the main flue, and its cavity communicates with the cavity of the main flue. The dust collection hood is connected to the end of the branch flue away from the main flue and communicates with its cavity. The cleaning device includes a dust agglomeration scraping mechanism, which is movably disposed within the cavity of the branch flue; a left winch mechanism; and a right winch mechanism. The left winch mechanism is located to the left of the main flue and supported on the flue support, and is positioned across the main flue... The pipe corresponds to the end of the flue branch pipe facing the main flue pipe. The right winch mechanism is located at the right end of the flue branch pipe and supported on the flue support, corresponding to the left winch mechanism. A first wire rope and a second wire rope are provided. One end of the first wire rope is fixed to the left winch mechanism, and the other end of the first wire rope enters the flue branch pipe cavity from the left side of the main flue pipe and is connected to the dust slab scraping mechanism. One end of the second wire rope is fixed to the right winch mechanism, and the other end of the second wire rope enters the flue branch pipe cavity from the right side of the flue branch pipe and is also connected to the dust slab scraping mechanism. A set of flue slab pre-wetting and softening mechanisms is provided. This set of flue slab pre-wetting and softening mechanisms is arranged at intervals above the flue branch pipe and communicates with the flue branch pipe cavity.

[0008] In a specific embodiment of the present invention, the structure of the right winch mechanism is the same as that of the left winch mechanism.

[0009] In another specific embodiment of the present invention, the left winch mechanism includes a support and a winch driven by a reducer driven by a motor. The support is disposed on the flue pipe support, the motor and the reducer are disposed on the support, the winch is connected to the reducer for transmission, one end of the first wire rope is fixed to the winch, and the first wire rope, under the winding of the winch, causes the dust caking mechanism to move from right to left within the flue branch pipe cavity of the flue branch pipe, and the second wire rope is in the unwinding state on the right winch mechanism. When the right winch mechanism is working and the second wire rope is in the winding state, the dust caking mechanism moves from left to right, and the first wire rope is in the unwinding state on the winch.

[0010] In another specific embodiment of the present invention, a first wire rope through-wall seal is provided on the wall of the main flue pipe and at a position corresponding to the first wire rope. The other end of the first wire rope passes through the first wire rope through-wall seal and then enters the flue pipe cavity through the main flue pipe cavity to connect with the dust and sludge scraping mechanism. On the wall of the right end of the flue pipe branch pipe and at a position corresponding to the second wire rope, a second wire rope through-wall seal is provided. The other end of the second wire rope passes through the second wire rope through-wall seal and then enters the flue pipe cavity to connect with the dust and sludge scraping mechanism.

[0011] In another specific embodiment of the present invention, the first wire rope through-wall seal and the second wire rope through-wall seal are flexible graphite braided packing, polytetrafluoroethylene packing or ceramic fiber packing.

[0012] In another specific embodiment of the present invention, the dust agglomerate scraping mechanism includes a body ring, a blade, a traction shaft, spokes, and a central ring. The traction shaft passes through the central ring and its middle part is welded and fixed to the central ring. The left and right ends of the traction shaft protrude from the central ring. The spokes are a set and are fixed radially spaced between the central ring and the opposite side of the body ring. The blade is disposed on the outer circumferential wall of the body ring on the outward-facing side. The other end of the first steel wire rope is fixed to the left end of the traction shaft, and the other end of the second steel wire rope is fixed to the right end of the traction shaft.

[0013] In a further specific embodiment of the present invention, a left lifting lug is fixed to the left end of the traction shaft, and a right lifting lug is fixed to the right end of the traction shaft. The other end of the first wire rope is fixed to the left lifting lug, and the other end of the second wire rope is fixed to the right lifting lug.

[0014] In a further specific embodiment of the invention, the blade is helical in shape.

[0015] In yet another specific embodiment of the present invention, each of the set of flue gas sludge pre-wetting and softening mechanisms includes a spray tank and a spray liquid inlet pipe. The spray tank is fixed to the upward-facing side of the flue gas branch pipe, and the spray tank cavity of the spray tank communicates with the flue gas branch pipe cavity. A spray tank cover is provided on the upper part of the spray tank. The end of the spray liquid inlet pipe facing the spray tank extends through the spray tank cover into the spray tank cavity and is fixed with a spray head. The end of the spray liquid inlet pipe away from the spray tank is connected to a pressurized spray liquid supply source.

[0016] In yet another specific embodiment of the present invention, the spray liquid supply source is a spray liquid supply pump station, and the spray liquid is water.

[0017] One of the technical effects of the present invention is that, because the left and right winch mechanisms can reciprocate the motion of the dust scraping mechanism to scrape off the dust caked on the cavity wall of the flue branch pipe, it helps to eliminate manual cleaning, reduce the workload of online operators, and ensure good cleaning results. Secondly, because the flue dust caked material is pre-wetted and softened by a set of flue dust caked material pre-wetting and softening mechanisms, it is easily introduced into the main flue dust pipe after being scraped by the dust caked material scraping mechanism and discharged under negative pressure by the airflow exhaust fan in the main flue dust pipe. Therefore, the purpose of cleaning the flue branch pipe can be effectively achieved through a three-in-one synergistic mechanism of softening, scraping, and fluidization, while ensuring the desired environmental protection. Thirdly, because it is an automatic cleaning process, there is no need to stop the sintering machine, thus ensuring sintering efficiency. Fourthly, because the overall structure of the cleaning device is very simple, it is very convenient for both installation and maintenance, and it demonstrates good cost-effectiveness.

Detailed Implementation

[0020] In order to better understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description below by way of embodiments. However, the description of the embodiments is not intended to limit the present invention. Any formal but not substantive equivalent transformations made based on the concept of the present invention should be considered within the scope of the present invention.

[0021] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on the current position. Figure 1 The location and state of the object are examples, and therefore should not be construed as a special limitation on the technical solution provided by the present invention.

[0022] Please see Figure 1 The diagram illustrates the structure of the flue system for the dust removal system of a sintering machine, including the main flue 1, branch flue 2, and dust hood 3. Normally, the main flue 1 and branch flue 2 are supported on a flue pipe bracket (not shown) during use. The end of the branch flue 2 facing the main flue 1 is orthogonally connected to the main flue 1, and its flue branch cavity 21 communicates with the main flue cavity 11 of the main flue 1. The dust hood 3 is connected to the end of the branch flue 2 away from the main flue 1 and communicates with the aforementioned branch flue cavity 21. The diagram also shows a dust agglomeration within the structure of the cleaning device system. A scraping mechanism 4, which is movably disposed within the aforementioned flue branch pipe cavity 21; a left winch mechanism 5 and a right winch mechanism 6, the left winch mechanism 5 being located on the left side of the aforementioned main flue pipe 1 and supported on the aforementioned flue pipe support (not shown in the figure), and corresponding to the end of the aforementioned flue branch pipe 2 facing the main flue pipe 1 across the main flue pipe 1; the right winch mechanism 6 being located on the right end of the flue branch pipe 2 and supported on the flue support, and corresponding to the aforementioned left winch mechanism 5; a first wire rope 7 and a second wire rope 8, one end of the first wire rope 7 ( Figure 1 The left end of the first wire rope 7 (as shown in the diagram) is fixed to the aforementioned left winch mechanism 5, while the other end of the first wire rope 7 ( Figure 1 The right end of the position shown) enters the flue branch pipe cavity 21 from the left side outside of the main flue 1 through the aforementioned main flue cavity 11 and is connected to the aforementioned dust and sludge scraping mechanism 4. One end of the second wire rope 8 ( Figure 1 The right end of the second wire rope 8 (as shown in the diagram) is fixed to the aforementioned right winch mechanism 6, while the other end of the second wire rope 8 ( Figure 1 The left end of the flue branch pipe 2 is introduced into the flue branch pipe cavity 21 from the outside of the right end of the flue branch pipe 2 and is also connected to the aforementioned dust and sludge scraping mechanism 4; a set of flue sludge pre-wetting and softening mechanisms 9 are arranged at intervals above the aforementioned flue branch pipe 2 and communicate with the aforementioned flue branch pipe cavity 21.

[0023] Since the end of the aforementioned flue branch pipe 2 facing the main flue pipe 1 is orthogonally connected to the main flue pipe 1, the relationship between the flue branch pipe 2 and the main flue pipe 1 is essentially T-shaped. Based on common knowledge in this field, it can be understood that a plurality of branches are typically distributed at intervals along the length of the main flue pipe 1. Figure 1The flue branch pipes 2 shown are each equipped with the cleaning device of this invention. That is, the number of cleaning devices is directly proportional to the number of flue branch pipes 2, and a dust suction hood 3 is attached to the right end of each flue branch pipe 2. Generally, the dust suction hood 3 corresponds to the unloading area or unloading point of the sintered pellet conveyor belt at the tail of the sintering machine. To facilitate understanding of this invention, the applicant... Figure 1 The sintered pellet 10 is shown in the figure.

[0024] The main flue duct 1 is typically evacuated by a dust collector fan (not shown in the figure) drawing water from the main flue duct cavity 11, discharging the slurry 20 that has been cleaned by the aforementioned cleaning device and introduced into the branch flue duct cavity 21. Furthermore, as is known from common knowledge in the art, the left and right hoisting mechanisms 5 and 6, and the flue duct sludge pre-wetting and softening mechanism 9 of the aforementioned dust collector fan and cleaning device system are powered by electricity and electrically controlled by an electrical controller during operation. Figure 1 In the document, the applicant also shows arrows 30 indicating the flow direction of the waste gas and the thin mud 20, so that the thin mud 20 reaches the discharge point.

[0025] In this embodiment, since the structure of the aforementioned right winch mechanism 6 is the same as that of the aforementioned left winch mechanism 5, the applicant will only describe the left winch mechanism 5. The left winch mechanism 5 includes a support 51 and a winch 52 driven by a motor-driven reducer. The support 51 is mounted on the aforementioned flue pipe support, and the aforementioned motor and reducer are mounted on the support 51. The aforementioned winch 52 is connected to the reducer via a transmission connection, and the winch 52 is rotated by the final stage power output shaft of the reducer. The aforementioned first steel wire... One end of rope 7 is fixed to the winch. The first wire rope 7, when wound up by the winch 52, causes the aforementioned dust and tar scraping mechanism 4 to move from right to left within the flue branch pipe cavity 21 of the aforementioned flue branch pipe 2, while the aforementioned second wire rope 8 is in a retracted state. When the right winch mechanism 6 operates, causing the second wire rope 8 to be wound up on the right winch mechanism 6, the aforementioned dust and tar scraping mechanism 4 moves from left to right, and the aforementioned first wire rope 7 is in a retracted state on the aforementioned winch 52. The motors of the aforementioned left and right winch mechanisms 5 and 6 are electrically connected to the aforementioned electrical control system.

[0026] See you later Figure 1A first wire rope through-wall seal 12 is provided on the wall of the main flue pipe 1 at a position corresponding to the first wire rope 7. The other end of the first wire rope 7 passes through the first wire rope through-wall seal 12, passes through the main flue pipe cavity 11, enters the flue branch pipe cavity 21, and connects with the dust and sludge scraping mechanism 4. A second wire rope through-wall seal 22 is provided on the wall of the flue branch pipe at the right end of the flue branch pipe 2 at a position corresponding to the second wire rope 8. The other end of the second wire rope 8 passes through the second wire rope through-wall seal 22 and is introduced into the flue branch pipe cavity 21 to connect with the dust and sludge scraping mechanism 4.

[0027] In this embodiment, the aforementioned first wire rope through-wall seal 12 and second wire rope through-wall seal 22 are made of polytetrafluoroethylene packing, but flexible graphite braided packing or even ceramic fiber packing can also be used.

[0028] Please see Figure 2 and Figure 3 And combined Figure 1 The aforementioned dust and sludge scraping mechanism 4 includes a body ring 41, a blade 42, a traction shaft 43, spokes 44, and a central ring 45. The traction shaft 43 passes through the central ring 45 and is welded to the central ring 45 at its center. The left and right ends of the traction shaft 43 protrude from the central ring 45. The spokes 44 are a set and are fixed radially between the central ring 45 and the opposite side of the body ring 41. The blade 42 is disposed on the outer wall of the circumferential direction on the outward-facing side of the body ring 41. The other end of the aforementioned first wire rope 7 is fixed to the left end of the aforementioned traction shaft 43, and the other end of the aforementioned second wire rope 8 is fixed to the right end of the aforementioned traction shaft 43.

[0029] Depend on Figure 3 As shown, a left lifting lug 431 is fixed at the left end of the aforementioned traction shaft 43, and a right lifting lug 432 is fixed at the right end of the traction shaft 43. The other end of the aforementioned first wire rope 7 is fixed to the left lifting lug 431, and the other end of the aforementioned second wire rope 8 is fixed to the right lifting lug 432.

[0030] In this embodiment, the aforementioned blade 42 is helical in shape.

[0031] from Figure 1 As can be seen from the illustration and common sense, the aforementioned blade 42 must maintain a reasonable gap with the cavity wall of the flue branch pipe 21 as required by the process. The slab layer 40 in this gap is the aforementioned dust slab, which can also be called CaO slab.

[0032] See you later Figure 1Each of the aforementioned set of flue gas sludge pre-wetting and softening mechanisms 9 includes a spray tank 91 and a spray liquid inlet pipe 92. The spray tank 91 is fixed on the upward side of the aforementioned flue gas branch pipe 2, and the spray tank cavity 911 of the spray tank 91 is connected to the aforementioned flue gas branch pipe cavity 21. A spray tank cover 912 is provided on the upper part of the spray tank 91. One end of the spray liquid inlet pipe 92 facing the spray tank 91 extends through the spray tank cover 912 into the spray tank cavity 911, and a spray head 921 is fixed thereon. The end of the spray liquid inlet pipe 92 away from the spray tank 91 is connected to a pressurized spray liquid supply source.

[0033] The aforementioned source of the spraying liquid is a spraying liquid supply pump station, and the aforementioned spraying liquid is water.

[0034] In describing the use of this invention, the applicant first needs to clarify that the coordinated operation time of the left and right winch mechanisms 5 and 6 for winding and unwinding the first and second wire ropes 7 and 8, respectively, is set by the PLC of the aforementioned electrical controller. Furthermore, the aforementioned sludge layer 40 deposited on the cavity wall (inner wall) of the flue branch pipe cavity 21 is removed periodically or irregularly. When the left winch mechanism 5 operates, causing the first wire rope 7 to be wound up by the winch 52 (i.e., the first wire rope winch), the first wire rope 7 pulls the soot sludge scraping mechanism 4 from right to left. Simultaneously, the right winch mechanism 6 operates in the opposite direction, causing the second wire rope 8 previously wound on its winch (i.e., the second wire rope winch) to unwind. During this process, the blade 42 scrapes the sludge layer 40 off the inner wall of the flue branch pipe cavity 21. Since the process of the soot sludge scraping mechanism 4 moving to the right is similar to the aforementioned process of moving to the left, the applicant will not elaborate further. It is important to emphasize that before and during the reciprocating movement of the dust and sludge scraping mechanism 4 driven by the left and right hoisting mechanisms 5 and 6 (i.e., throughout the entire process), the aforementioned set of flue dust and sludge pre-wetting and softening mechanisms 9 operates, spraying water from the spray heads 921. That is, the spray heads 921 of the flue dust and sludge pre-wetting and softening mechanism 9 (also called the "spraying system") pre-wet and soften the highly viscous lime sludge (reducing its bonding strength) because CaO reacts with water to release heat and become highly viscous Ca(OH)2 colloid. This, combined with the reciprocating movement of the dust and sludge scraping mechanism 4, results in strong mechanical stripping. The stripped thin slurry 20 is then... Figure 1 Arrow 3 indicates the direction towards the discharge point. The working time of the left and right hoisting mechanisms 5 and 6 each time they drive the dust and sludge scraping mechanism 4 is determined by the production site as needed. It can be periodic, irregular, or continuous. Continuous means that as long as the aforementioned unloading point (also known as the "dust-generating point") is unloading, the cleaning device will work continuously.

[0035] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
