Description

Technical Field

[0001] The invention relates to the technical field of smoke absorption and treatment on an aluminum slag separator, and in particular to a matching smoke absorption pipeline suitable for an aluminum slag separator. Background Art

[0002] Aluminum slag separator is a kind of equipment used to separate aluminum slag and aluminum ash. It is mainly used in the fields of refining and recycling aluminum, producing basic aluminum chloride water purifier, replacing part of the slag remover with joint materials in electrolytic aluminum plants, desulfurization and deoxidation agent for refining furnaces in steel plants, and high-strength mortar for the construction industry. During operation, the aluminum slag separator will produce flue gas containing dust, gaseous pollutants, etc., which are harmful to the environment and human health. Effective flue gas treatment is required, which is usually divided into a spray tower and a bag dust collector combination. The flue gas first enters the spray tower, and some gaseous pollutants and dust are removed by the spray liquid, and then enters the bag dust collector to further remove the remaining dust. It can achieve better treatment effects, but the equipment occupies a large area and has a high operating cost. The other is a combination of an activated carbon adsorption box and an electrostatic precipitator. The activated carbon adsorption box is used to adsorb gaseous pollutants, and then the electrostatic precipitator is used to remove dust. This can effectively remove a variety of pollutants, but the activated carbon adsorption box needs to be replaced regularly, and the operation and maintenance are relatively complicated. In practical applications, it is usually necessary to select appropriate flue gas treatment methods or combined processes according to the specific working conditions, flue gas composition and emission standards of the aluminum slag separator to ensure that the flue gas meets the emission standards. At the same time, considering that the flue gas temperature generated by the aluminum slag separator is high and the smoke is large, the tail absorption treatment is easy to saturate. Therefore, some large particle impurities are intercepted in the smoke dust pipeline, which is conducive to the efficient operation of the subsequent dust removal equipment. To this end, we propose a matching smoke absorption pipeline suitable for aluminum slag separator. Summary of the invention

[0003] The purpose of the present invention is to provide a matching smoke absorption pipeline suitable for an aluminum slag separator to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a matching smoke absorption pipeline suitable for an aluminum slag separator, comprising a dust flushing pipe 1 and a dust flushing pipe 2, wherein the dust flushing pipe 1 and the dust flushing pipe 2 are arranged correspondingly, and a branch pipe 1 and a branch pipe 2 are connected and fixed between the dust flushing pipe 1 and the dust flushing pipe 2, and an air inlet is provided on the branch pipe 1, and an air outlet is provided on the branch pipe 2; The branch pipe one and the branch pipe two are respectively provided with an air filling port and an ash discharge port. The tops of the dust flushing pipe one and the dust flushing pipe two are fixed with a transmission assembly by bolts. The transmission assembly is located inside the dust flushing pipe one and the dust flushing pipe two and is fixedly connected with a rotating column. The dust flushing pipe one and the dust flushing pipe two and are located on the rotating column and are fixedly connected with an ash blocking cylinder.

[0005] Furthermore, the outer wall of the rotating column is slidably connected with a sliding sleeve on the ash blocking cylinder, the outer wall of the rotating column is symmetrically and movably connected with a rotating arm inside the ash blocking cylinder, one end of the rotating arm is movably connected with a movable ball, and connecting rods are symmetrically and movably connected on both sides of the outer wall of the sliding sleeve, and the connecting rods are respectively movably connected to one end of the rotating arm.

[0006] Furthermore, the inner walls of the first dust flushing pipe and the second dust flushing pipe are symmetrically fixed with limiting frames, grooves are symmetrically opened on both sides of the limiting frames, and scraping strips are slidably connected in the limiting frames and located in the grooves.

[0007] Furthermore, a pressure strip is slidably connected inside the dust flushing pipe 1 and the dust flushing pipe 2 and located at the top of the dust blocking cylinder, one end of the pressure strip abuts against the top cut surface of the scraper strip, and the other end of the pressure strip abuts against the outer wall of the sliding sleeve.

[0008] Furthermore, branch pipe one and branch pipe two are symmetrically and movably connected with a steering mechanism, the steering mechanism includes a rotating shaft and a valve cover, branch pipe one and branch pipe two are movably connected with a valve cover on a vertical section, and the valve covers on both sides rotate in opposite directions, branch pipe one and branch pipe two are movably connected with a rotating shaft, the two ends of the rotating shaft are respectively connected to the valve covers inside branch pipe one and branch pipe two, the outer wall of the rotating shaft is sleeved with a clamping strip, and a sliding strip is installed on the side of the clamping strip.

[0009] Furthermore, a control box is fixedly installed on the top of the branch pipe one, the slide bar is located at the bottom of the control box, and pressure gauges are installed on the dust flushing pipe one and the dust flushing pipe two.

[0010] The working method of the smoke dust absorption pipeline suitable for aluminum slag separator is: Dust collection monitoring in pipelines: The air inlet on branch pipe 1 between dust flushing pipe 1 and dust flushing pipe 2 is connected to the smoke pipe, and the dust-laden smoke enters dust flushing pipe 1 through branch pipe 1. The transmission assembly on the top of dust flushing pipe 1 drives the rotating column to rotate, and the dust shield installed on the rotating column rotates to intercept and purify the incoming smoke, and then it is discharged into the dust removal equipment through the air outlet on branch pipe 2. As the amount of impurities added on the outer wall of the dust shield increases, the efficiency of smoke passing through dust flushing pipe 1 decreases, and at the same time, the air pressure in dust flushing pipe 1 increases. The barometer obtains the real-time air pressure value until the air pressure value triggers the set air pressure threshold in the control box. At this time, the electric push rod at the bottom of the control box actively pushes the slide bar to slide, and as the shaft rotates, the direction of the upper valve cover of branch pipe 1 and branch pipe 2 is changed, and the smoke entering from the air inlet enters dust flushing pipe 2; Dust removal without stopping the machine: When the dust flushing pipe in idle state enters the dust removal mode, the transmission component increases the rotation speed of the rotating column, causing the rotation angle of the movable ball connected to the rotating arm to increase, and at the same time causing the sliding sleeve on the top of the ash retaining cylinder to slide downward, pressing down the entire limit frame upper pressure strip to contact the high-speed rotating ash retaining cylinder, mechanically cleaning the entire ash retaining cylinder, and at the same time the air inlet starts to take in air, and the dust-laden airflow is blown out from the ash discharge port.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a branch is installed on the matching smoke duct of the aluminum slag separator, and the parallel flow principle is used to perform single-side pipeline control. When the ash retaining cylinder in the pipeline is blocked, the flow path is switched in time to provide conditions for subsequent maintenance and cleaning, while not affecting normal smoke and dust circulation. The dust attached to the outer wall of the ash retaining cylinder increases with time, affecting the gas flow rate in the subsequent pipeline and causing the pipeline pressure to increase. The control box actively adjusts the detection path, drives the sliding bar to move to rotate the shaft, controls the rotation of the valve covers in branch one and branch two, and finally realizes the flow path adjustment. The subsequent transmission assembly increases the rotation speed of the rotating column, causing the movable ball at the end of the rotating arm to contact the inner wall of the ash retaining cylinder. At the same time, the downward pressing strip squeezes the scraping strip to contact the outer wall of the ash retaining cylinder, cooperates with the air intake at the inflation port, and discharges the scraped flue gas and dust from the ash discharge port, completing the self-cleaning of the pipeline.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-7 , the present invention provides a technical solution: like Figure 1 and Figure 2 As shown, the matching smoke dust absorption pipeline of the aluminum slag separator is mainly composed of a dust flushing pipe 1 and a dust flushing pipe 2, which are precisely arranged, and a branch pipe 1 3 and a branch pipe 2 4 are firmly connected between them, forming a stable and efficient smoke dust circulation channel structure; Among them, the branch pipe 1 3 is carefully provided with an air inlet 5, which is intended to accurately introduce the smoke generated during the aluminum slag separation process to ensure that the smoke can smoothly and efficiently enter the absorption pipeline system, while the branch pipe 2 4 is reasonably provided with an air outlet 6, so that the treated gas can be smoothly discharged, ensuring the continuity and effectiveness of the entire absorption process; The branch pipe 1 3 and the branch pipe 2 4 are also cleverly provided with an air inlet 11 and an ash discharge port 12. The setting of the air inlet 11 provides convenience for operations such as dust cleaning inside the pipeline. Active air inflation from the outside can effectively disturb the dust, and the subsequent scraper 19 can effectively guide the dust in the pipeline. The ash discharge port 12 can timely discharge the precipitated dust from the pipeline, maintain the clean state of the inside of the pipeline, and ensure its long-term stable and efficient operation. At the top of the dust flushing pipe 1 and the dust flushing pipe 2, the transmission assembly 10 is firmly fixed by high-strength bolts. The transmission assembly 10 penetrates into the dust flushing pipe 1 and the dust flushing pipe 2, and is reliably fixedly connected with the rotating column 13. The motor in the transmission assembly 10 drives the rotating column 13 to rotate. The rotating column 13, as the core rotating component, plays a key role in the dust flushing pipe 1 and the dust flushing pipe 2. At the same time, the transmission assembly 10 adjusts the speed of the rotating column 13 and also indirectly controls the scraper 19. The design of the dust blocking cylinder 17 can effectively prevent dust from flying around and guide the dust to flow along a predetermined path. As for the large particles of impurities contained in the smoke, they are intercepted by the dust blocking cylinder 17 and attached to its surface. Long-term operation will cause the holes on the outer wall of the entire dust blocking cylinder 17 to be blocked, affecting the subsequent circulation of smoke. By using the air pressure changes when the dust flushing pipe 1 and the dust flushing pipe 2 are working, the blockage status is estimated and monitored, such as Figure 4 As shown, a control box 7 is installed on the entire branch pipe 3. The control box 7 is used to obtain and process the real-time data transmitted by the barometer 8. By setting the pipeline air pressure threshold in the control box 7, the obtained real-time air pressure data is compared with the air pressure threshold. When the air pressure value in the dust flushing pipe 1 is greater than the set air pressure threshold, it means that the outer wall of the dust blocking cylinder 17 in the dust flushing pipe 1 is seriously clogged with dust. At this time, it needs to be cleaned, and the dust flushing pipe 2 2 is activated for subsequent smoke purification; To this end, by setting up parallel circulation pipelines, and then performing single-side pipeline control, and timely switching the circulation path when the ash retaining cylinder 17 in the pipeline is blocked, providing subsequent maintenance and cleaning conditions, while not affecting the normal smoke and dust circulation, that is, the entire aluminum slag separator can realize automatic processing of smoke and dust on the pipeline without stopping; As for the control of flue gas flow diversion, Figure 5 As shown in the entire steering mechanism 9, a rotating shaft 901 is movably connected on the vertical section of the branch pipe 1 3 and the branch pipe 2 4. The rotating shaft 901 is located inside the branch pipe 1 3 and the branch pipe 2 4 and is fixedly connected to a valve cover 903. The valve covers 903 connected to the ends of the rotating shaft 901 on both vertical sides turn in opposite directions, and a clamping strip 902 is sleeved and fixed on the outer side of the rotating shaft 901. At the same time, a slide bar 904 is slidably connected at the bottom of the control box 7. A groove is opened on the slide bar 904. The bottom protrusion of the clamping strip 902 is engaged with the groove on the slide bar 904. With the issuance of the path adjustment signal, the electric push rod arranged at the bottom of the control box 7 pushes the entire slide bar 904 to move, and the clamping strip 902 rotates with the rotation to realize the synchronous rotation of the valve cover 903 at the end of the rotating shaft 901. Figure 5 As shown, when the rotating shaft 901 rotates, the smoke entering from the air inlet 5 flows into the dust flushing pipe 1 along the branch pipe 1 3, and the branch pipe 1 3 is located at the side of the dust flushing pipe 2 2 and is in a closed state; When the entire dust flushing pipe 1 needs to be cleaned of dust, such as Figure 6As shown, a limiting frame 18 is symmetrically fixed on the dust flushing pipe 1 and on the outer wall of the dust blocking cylinder 17, and a scraper 19 is slidably connected inside the limiting frame 18. According to the orientation of the grooves on the outer walls on both sides of the limiting member, under normal placement, the scraper 19 slides toward the bottom of the groove, causing the entire scraper 19 to be separated from the outer wall of the dust blocking cylinder 17. At the same time, the top of the entire scraper 19 is provided with an inward cut surface, and a pressure strip 20 is symmetrically slidably connected to the inner wall of the dust flushing pipe 1, and the bottom of the pressure strip 20 protrudes and abuts against the top cut surface of the scraper 19; Whenever the pressure strip 20 moves downward, it squeezes the entire scraper strip 19 to slide along the upward inclined groove, causing the entire scraper strip 19 to start moving toward the outer wall of the dust blocking cylinder 17, and finally completes the contact with the outer wall of the dust blocking cylinder 17. In the process of the rotating column 13 driving the dust blocking cylinder 17 to rotate, the dust on the outer wall of the dust blocking cylinder 17 is scraped off, and the outer wall of the dust blocking cylinder 17 is automatically cleaned. Without the squeezing process of the pressure strip 20, the scraper strip 19 can also automatically break away from the contact with the outer wall of the dust blocking cylinder 17 by its own weight, preventing the scraper strip 19 from contacting the dust blocking cylinder 17 for a long time and causing aggravated wear. For the entire layering strip 20 activity control, such as Figure 7 As shown, a rotating arm 14 is symmetrically connected to the outer wall section of the rotating column 13, and one end of the rotating arm 14 is movably connected to a movable ball 15, and the outer wall of the movable ball 15 is evenly provided with protrusions. As the entire rotating column 13 rotates, the movable ball 15 on the rotating arm 14 automatically suspends due to the centrifugal force generated by the rotation. The faster the rotating column 13 rotates, the larger the suspension angle of the movable ball 15, and correspondingly, the larger the downward bending angle of the other end of the rotating arm 14; A sliding sleeve 16 is also sleeved on the rotating column 13 at the top of the dust blocking cylinder, and the entire sliding sleeve 16 is slidably connected to the rotating column 13. The connecting rod of the outer wall of the rotating sleeve is movably connected to the end of the rotating arm 14, so that the entire sliding sleeve 16 is actively pressed down to move downward during the rotation of the rotating arm 14, and one side of the entire pressure strip 20 is located at the bottom of the sliding sleeve 16. The sliding sleeve 16 moving downward will push the entire pressure strip 20 to squeeze the scraping strip 19, thereby realizing a chain action and completing the movement of the scraping strip 19 to the outer wall of the dust blocking cylinder 17; Under normal conditions, the rotation speed of the entire rotating column 13 is relatively low, and the smoke flowing in from the side of the branch pipe 3 is discharged upward along the dust shield cylinder. When the entire dust flushing pipe 1 needs to be cleaned, the speed of the motor in the transmission assembly 10 increases, and the rotation amplitude of the rotating arm 14 increases, causing the movable ball 15 at the end of the rotating arm 14 to begin to contact the inner wall of the dust shield cylinder. Under the contact and impact of the movable ball 15, the vibration generated is conducive to the dust falling off the outer wall of the dust shield cylinder. At the same time, the active contact of the scraper strip 19 will also scrape and clean the outer wall of the dust shield cylinder 17, and dust will continuously come into the gap of the dust flushing pipe 1. To avoid secondary contamination of the suspended smoke by dust, the air filling port 11 installed on the outer wall of the dust flushing pipe 1 starts to actively intake air, and the circulating airflow pushes the smoke to be ejected from the ash discharge port 12, thereby achieving matching smoke absorption and collection. By intercepting some large particles of impurities in the smoke duct, it is beneficial to the efficient operation of subsequent dust removal equipment.

[0016] The working principle of the present invention is as follows: the air inlet 5 on the branch pipe 3 between the dust flushing pipe 1 and the dust flushing pipe 2 is connected to the smoke pipe, and the dust-laden smoke enters the dust flushing pipe 1 through the branch pipe 3. The transmission assembly 10 on the top of the dust flushing pipe 1 drives the rotating column 13 to rotate, and the dust shielding cylinder installed on the rotating column 13 rotates to intercept and purify the incoming smoke, and then it is discharged into the dust removal equipment through the air outlet 6 on the branch pipe 2 4. With the increase of the amount of impurities added on the outer wall of the dust shielding cylinder, the efficiency of smoke passing through the dust flushing pipe 1 is reduced, and at the same time, the air pressure in the dust flushing pipe 1 is increased, and the barometer 8 obtains the real-time air pressure value until the air pressure value triggers the set air pressure threshold in the control box 7. At this time, the electric push rod at the bottom of the control box 7 actively pushes the slide bar 904 to slide, and with the rotation of the rotating shaft 901, the direction of the valve cover 903 on the branch pipe 3 and the branch pipe 2 4 is changed, and the smoke entering through the air inlet 5 enters the dust flushing pipe 2; The dust flushing pipe 1 in the idle state enters the dust removal mode, and the transmission assembly 10 increases the rotation speed of the rotating column 13, causing the movable ball 15 connected to the rotating arm 14 to increase the rotation angle, and at the same time causing the top sleeve 16 of the dust blocking cylinder 17 to slide downward, pressing down the entire limit frame 18 and the upper pressure strip 20 to contact the high-speed rotating dust blocking cylinder 17, mechanically cleaning the entire dust blocking cylinder 17, and at the same time, the air inlet 11 starts to take in air, and blows the dust-containing airflow out from the dust discharge port 12.
