Description

Technical Field

[0001] This utility model belongs to the field of steel slag hot quenching dust removal technology, specifically relating to a high-efficiency steel slag hot quenching dust removal device. Background Technology

[0002] During the hot quenching process of steel slag, after the high-temperature steel slag is poured into the quenching pool, a large amount of water needs to be sprayed on the steel slag. During this period, an excavator is also needed to stir it. After the quenching is completed, the slag is discharged by the excavator to the vibrating screen, and then transported by belt conveyor and transfer station. The whole process involves slag pouring, quenching, turning, slag discharge, screening, belt conveyor, crushing and other processes. During this process, a large amount of humid and dusty waste gas is generated, which pollutes the plant and the surrounding environment.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN221207356U discloses "a high-efficiency steel slag hot quenching dust collector", which includes a box body, a dust collector cylinder fixedly connected to the top of the box body, the box body and the dust collector cylinder being connected, a dust removal mechanism being provided inside the dust collector cylinder, an air supply mechanism being provided inside the box body, the dust removal mechanism including an air inlet located on one side of the box body, an air outlet being provided at the top of the dust collector cylinder, and a first-stage swirl plate fixedly connected to both sides of the inner cavity of the dust collector cylinder.

[0004] However, actual industrial applications have revealed significant flaws in this technical solution. The exhaust gas generated during the hot quenching of steel slag contains a high concentration of large particulate dust. During operation, the nozzles of the three-stage atomizing and condensing layer directly contact this exhaust gas containing large particulate dust. Furthermore, the nozzle structure lacks a pre-interception device, failing to prevent the pre-blocking of large particulate dust. Over long-term operation, dust easily accumulates and clumps within the nozzle's channels. Actual monitoring data shows that when the steel slag dust concentration reaches 50 g / m³... 3 Under operating conditions of 30% and above, after 48 hours of continuous operation, the nozzle will have a clogging rate of over 30%. Once the nozzle is clogged, the atomization effect will be severely reduced, resulting in the dust entering the dust removal system not being able to fully combine with the water mist, which will greatly affect the dust removal efficiency and make it difficult to meet the strict environmental emission requirements.

[0005] To address the aforementioned issues, this application proposes a high-efficiency steel slag hot quenching dust removal device. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a high-efficiency steel slag hot quenching dust removal device, which features the ability to pre-intercept large dust particles in exhaust gas, reduce nozzle clogging, and improve dust removal efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example

[0034] Please see Figures 1-7 This utility model provides the following technical solution: a high-efficiency steel slag hot quenching dust removal device, comprising a housing 1 and a dust removal cylinder 2 disposed on the housing 1.

[0035] An air inlet 3 is provided on one side of the housing 1, and an air outlet 4 is provided on the top of the dust collector 2;

[0036] It also includes a screening component, which is located inside the housing 1 and is used to screen larger steel slag particles.

[0037] The screening component includes a mounting hole 5 on the housing 1, a connecting frame 6 that slides with the mounting hole 5, and a first filter screen 8 fixed on the connecting frame 6. In use, the connecting frame 6 is first slidably inserted into the housing 1 through the mounting hole 5. The first filter screen 8 pre-intercepts large dust particles entering the housing 1, preventing them from entering the dust collector 2 and clogging the nozzles, thus improving dust removal efficiency. Subsequently, the exhaust gas after being screened by the first filter screen 8 continues to flow into the dust collector 2 and undergoes staged dust removal through the primary atomizing condensation layer, the secondary cyclone plate, the secondary atomizing condensation layer, the tertiary atomizing condensation layer, and the high-efficiency demister dust collector. Finally, clean gas is discharged from the outlet 4, achieving the purpose of efficient dust removal. In addition, the design of the first filter screen 8 not only effectively intercepts large dust particles, but its sliding connection method also makes the first filter screen 8 easy to disassemble and clean, thereby ensuring the continuous and efficient operation of the dust removal device.

[0038] Preferably, by Figure 1 and Figure 3As shown in this embodiment, a second filter screen 9 is also provided inside the connecting frame 6 near the air inlet 3. The second filter screen 9 is located below the air inlet 3. This can prevent larger steel slag particles from being directly intercepted by the second filter screen 9, so that the exhaust gas flows into the interior of the housing 1 from the top of the second filter screen 9 and is filtered by the first filter screen 8. The larger steel slag particles filtered by the first filter screen 8 will fall into the interior of the connecting frame 6. The second filter screen 9 can prevent larger steel slag particles from falling out of the connecting frame 6 and damaging other components of the dust removal device, thereby improving the overall stability and service life of the dust removal device.

[0039] Preferably, by Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, a fixing plate 10 is provided on one side of the connecting frame 6, and an insertion hole 11 is provided on the fixing plate 10;

[0040] A pair of mounting plates 12 are provided on one side of the housing 1 near the connecting frame 6. A pin 13 is slidably connected to the pair of mounting plates 12. One end of the pin 13 passes through the mounting plate 12 near the connecting frame 6 and is inserted into the insertion hole 11; the other end passes through the other mounting plate 12 and is provided with a moving piece 16. A first fixing piece 14 is provided on the outer wall of the pin 13, and a first return spring 15 is also sleeved on the outer wall of the pin 13. The two ends of the first return spring 15 abut against the first fixing piece 14 and one of the mounting plates 12, respectively. In use, when it is necessary to remove the first filter screen... When cleaning the filter 8 from the housing 1, the movable piece 16 can be manually pulled. The movable piece 16 causes the pin 13 to slide on the mounting plate 12. At this time, the first return spring 15 is squeezed by the first fixed piece 14, and deforms to generate elastic force until the pin 13 slides out completely from the insertion hole 11. At this time, the fixing of the connecting frame 6 can be released. Then, the connecting frame 6 can be manually pulled, and the connecting frame 6 slides in the mounting hole 5 until the connecting frame 6 is completely pulled out from the housing 1. At this time, the first filter screen 8 can be cleaned or replaced. The operation is convenient and highly practical.

[0041] Preferably, by Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, a support plate 23 is provided on one side of the dust collector 2, and a pair of guide rods 19 are slidably connected on the support plate 23. A scraper 20 is provided at one end of the pair of guide rods 19.

[0042] The top of the housing 1 is provided with a clearance hole 17. The scraper 20 passes through the clearance hole 17 and extends into the interior of the housing 1. A sealing shell 18 is also provided on the housing 1 above the clearance hole 17. A pair of guide rods 19 pass through the sealing shell 18 through the through hole. The scraper 20 is located inside the sealing shell 18.

[0043] A push rod 24 is slidably connected to the support plate 23. One end of the push rod 24 passes through the sealing shell 18 and is fixedly connected to the scraper 20. A second fixing plate 21 is fixedly mounted on the outer wall of each of the two guide rods 19. A second return spring 22 is sleeved on the outer wall of each of the two second fixing plates 21. The two ends of the second return spring 22 abut against the second fixing plate 21 and the sealing shell 18, respectively. When too much dust accumulates on the first filter screen 8, the push rod 24 can be pushed downwards. The push rod 24 drives the scraper 20 to slide downwards along the clearance hole 17 under the guidance of the guide rods 19 until the scraper 20 scrapes off the dust accumulated on the first filter screen 8. At this time, the scraped dust will fall to the bottom of the box 1 under gravity, facilitating subsequent unified processing. The cleaning process effectively prevents the first filter screen 8 from becoming clogged due to excessive dust accumulation, ensuring the efficient and stable operation of the dust removal device. Simultaneously, the sealing shell 18 prevents external dust from entering the housing 1, ensuring the cleanliness of the dust removal device's interior. Furthermore, the outer walls of both guide rods 19 are fixed with second fixing plates 21, and the outer walls of both second fixing plates 21 are fitted with second return springs 22. The two ends of the second return springs 22 abut against the second fixing plates 21 and the sealing shell 18, respectively. When the push rod 24 is released, the elastic force of the second return springs 22 pushes the second fixing plates 21, causing the scraper 20 to quickly return to its original position, facilitating future use and improving the practicality and convenience of the dust removal device.

[0044] Components not described in detail in this article are existing technologies.

[0045] The working principle and usage process of this utility model: Moist and dusty exhaust gas enters the housing 1 through the air inlet 3. It first undergoes preliminary treatment by the screening component. Large particles of steel slag dust in the exhaust gas are intercepted by the first filter screen 8, while fine dust and moisture continue to pass through the second filter screen 9 and enter the dust collector 2.

[0046] After entering the dust collector 2, the exhaust gas sequentially passes through a primary atomizing and condensing layer, a secondary cyclone plate, a secondary atomizing and condensing layer, a tertiary atomizing and condensing layer, and a high-efficiency demister dust collector. In the primary atomizing and condensing layer, the nozzles evenly spray water mist, ensuring full contact with the dust in the exhaust gas, allowing the dust particles to combine with the water mist and form larger particles. The secondary cyclone plate guides the exhaust gas in a spiral motion, using centrifugal force to throw larger particles towards the cylinder wall, further achieving gas-solid separation. The secondary atomizing and condensing layer further condenses the dust in the exhaust gas. The tertiary atomizing and condensing layer further refines the water mist, deeply treating any remaining fine dust. Finally, the high-efficiency demister dust collector thoroughly removes the residual water mist and dust from the exhaust gas after multiple treatments, ensuring that the discharged gas meets cleanliness standards and is discharged from the outlet 4.

[0047] A transparent observation window can be installed on the housing 1. During the operation of the device, the operator can observe the interception of the first filter screen 8 through the transparent observation window. When it is found that a lot of dust has accumulated on the first filter screen 8, push the push rod 24. The scraper 20 slides down along the clearance hole 17 under the guidance of the guide rod 19, scraping the dust on the first filter screen 8 to the bottom of the housing 1. After cleaning is completed, release the push rod 24. Under the action of the second return spring 22, the scraper 20 quickly returns to its original position, preparing for the next cleaning.

[0048] When the first filter screen 8 needs to be deeply cleaned or replaced, manually pull the movable piece 16 to make the pin 13 slide on the mounting plate 12, compress the first return spring 15, and make the pin 13 slide out of the insertion hole 11, releasing the fixation of the connecting frame 6. Then pull the connecting frame 6 to pull it out of the mounting hole 5, so that the first filter screen 8 can be cleaned or replaced. After the operation is completed, reinsert the connecting frame 6 into the mounting hole 5, release the movable piece 16, and under the elastic force of the first return spring 15, the pin 13 reinserts into the insertion hole 11, fixing the connecting frame 6, so that the dust removal device returns to normal operation. Through the above working process, this dust removal device achieves efficient treatment of the humid and dusty exhaust gas generated during the hot quenching of steel slag, while ensuring the stable operation and convenient maintenance of the device.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
