Description

Technical Field

[0001] This utility model relates to the field of residual anode carbon block treatment technology, and in particular to a dust removal device for a residual anode carbon block treatment silo. Background Technology

[0002] The residual anode carbon block treatment facility is a core facility in the aluminum electrolysis industry specifically used for receiving, temporarily storing, crushing, screening, and resource-based treatment of "residual anode carbon blocks." It is a key link connecting aluminum electrolysis production and solid waste resource utilization. Its core function is to achieve the reduction and harmless treatment of residual anode carbon blocks and the recovery of valuable components, while avoiding secondary pollution.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In existing processing facilities, loaders are used for stacking materials and loading charcoal blocks onto transport vehicles for a long time. However, during the above operations, charcoal powder is easily generated in large quantities due to mechanical disturbances, material transfer drop, and other factors. This not only poses a threat to the occupational health of the workers, but may also cause dust pollution to the surrounding environment, which is significantly different from the current environmental protection requirements and low-carbon production concepts. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of generating a lot of dust when residual anode carbon blocks are used in the stacking area and loading area, which not only affects health, but also easily causes pollution to the surrounding environment. To this end, we propose a dust removal device for the residual anode carbon block processing warehouse.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dust removal device for a residual anode carbon block processing silo, comprising a mounting frame, a dust removal box and a fan fixedly mounted on the upper surface of the mounting frame, the mounting frame being located between the loading area and the stacking area, the outer surface of the dust removal box having an air inlet and an air outlet, the air outlet being connected to one end of the fan via a pipe flange, one end of the air inlet being flanged to an air inlet pipe, one end of the air inlet pipe being connected via a tee to the main pipe of the loading area and the main pipe of the stacking area respectively, the outer surface of both the main pipe of the loading area and the main pipe of the stacking area being equipped with an electric regulating valve, and an organic bypass box being installed on the upper surface of the mounting frame. Each set of electric regulating valves is connected to the signal box next to the machine. The outer surfaces of the main pipe in the loading area and the main pipe in the stacking area are respectively equipped with branch pipes. The bottom of the branch pipes is equipped with a dust collection hood. There are multiple sets of branch pipes and dust collection hoods. Each set of branch pipes is equipped with a manual regulating valve. By using the dust collection hoods set in the loading area and the stacking area respectively, the dust generated in these two areas can be effectively collected, reducing dust pollution. The electric regulating valves, the machine box next to the machine and the manual regulating valves can be easily switched on-site according to the actual situation, so as to flexibly adjust the dust collection air volume in each area and effectively prevent carbon dust from flying throughout the process.

[0006] Preferably, the dust collection box includes a lower chamber fixedly installed inside the mounting frame and an upper chamber fixedly installed on the upper surface of the lower chamber. The air inlet is located on the outer surface of the lower chamber and the air outlet is located on the outer surface of the upper chamber, for collecting dust.

[0007] Preferably, the inner wall of the lower compartment near the air inlet is equipped with a metal mesh filter plate to block large dust particles and reduce the burden on subsequent filtration.

[0008] Preferably, the upper chamber is equipped with a medium-efficiency filter plate, a high-efficiency filter plate and an activated carbon adsorption plate from bottom to top, which performs multi-stage filtration and adsorption of dust, effectively removing dust and harmful gases.

[0009] Preferably, the outer surface of the upper compartment is hinged with a movable door, and the interior of the movable door is equipped with an observation window, which facilitates the staff to observe and maintain the interior of the upper compartment.

[0010] Preferably, the outer surface of the upper chamber is provided with a pulse assembly. The pulse assembly includes a support frame fixedly installed on the outer surface of the upper chamber and a pulse air bag set on the upper surface of the support frame.

Each set of nozzles is connected to the interior of the upper chamber to periodically clean the dust of the medium-efficiency filter plate inside the upper chamber.

[0011] Preferably, the inner wall of the pipeline is equipped with a concentration detection sensor, which is connected to the signal of the machine-side box to monitor the dust removal effect, ensure that the discharged gas meets environmental protection requirements, and allow for timely shutdown and adjustment in case of any abnormality.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, the device first precisely controls the opening and closing of the electric regulating valves in the loading area or stacking area via a machine-side control box according to actual needs. After adjustment, the fan is started, and the negative pressure suction generated by the fan allows the dust-laden gas generated during operation to smoothly enter the branch pipes through the dust collection hood. Simultaneously, the airflow in each branch pipe can be flexibly adjusted using manual regulating valves to ensure optimal dust collection in different areas. Subsequently, the dust-laden gas is collected through the main pipe in the loading area or stacking area and then transported to the dust collection box for purification via the air inlet pipe. Therefore, it can effectively collect and treat the carbon dust generated during the entire process of stacking operations by the loader at the east end of the warehouse and loading operations of transferring carbon blocks to transport vehicles, curbing carbon dust emissions at the source and ensuring air quality and a clean production environment in the work area.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: a dust removal device for a residual anode carbon block processing warehouse, including: a mounting frame 1, and a dust removal box 2 and a fan 3 fixedly installed on the upper surface of the mounting frame 1. The mounting frame 1 is located between the loading area and the stacking area. The outer surface of the dust removal box 2 has an air inlet 21 and an air outlet 22. One end of the air outlet 22 is connected to one end of the fan 3 through a pipe 23 flange. One end of the air inlet 21 is flanged to an air inlet pipe 4. One end of the air inlet pipe 4 is connected to the loading area main pipe 41 and the stacking area main pipe 42 through a tee. The outer surfaces of the loading area main pipe 41 and the stacking area main pipe 42 are each equipped with an electric regulating valve 43. The upper surface of the mounting frame 1 Two machine-side boxes 5 are required, both installed on-site, for manual switching control of dust extraction between the loading area and the stacking area. Each set of electric regulating valves 43 is connected to the machine-side box 5. The total designed air volume for the corresponding areas of the loading area main pipe 41 and the stacking area main pipe 42 is 90,000 cubic meters / hour, and the two areas are switched alternately through the electric regulating valves 43. Branch pipes 6 are respectively installed on the outer surface of the loading area main pipe 41 and the stacking area main pipe 42. Dust extraction hoods 61 are installed at the bottom of the branch pipes 6. There are multiple sets of branch pipes 6 and dust extraction hoods 61, and each set of branch pipes 6 is equipped with a manual regulating valve 62 inside.

[0017] Reference Figures 1-4 As shown in this embodiment: the dust collection box 2 includes a lower chamber 24 fixedly installed inside the mounting frame 1, and an upper chamber 25 fixedly installed on the upper surface of the lower chamber 24. The air inlet 21 is located on the outer surface of the lower chamber 24, and the air outlet 22 is located on the outer surface of the upper chamber 25. The dust-laden gas enters the lower chamber 24 from the air inlet 21, undergoes preliminary treatment, and then enters the upper chamber 25 for further filtration. Finally, it is discharged from the air outlet 22.

[0018] A metal mesh filter plate 241 is installed on the inner wall of the lower chamber 24 near the air inlet 21. After the dust-laden gas enters the lower chamber 24, large dust particles are first intercepted by the metal mesh filter plate 241, which plays a preliminary filtering role.

[0019] The upper chamber 25 is equipped with a medium-efficiency filter plate 251, a high-efficiency filter plate 252 and an activated carbon adsorption plate 253 arranged from bottom to top. The medium-efficiency filter plate 251 and the high-efficiency filter plate 252 can remove dust, and the activated carbon adsorption plate 253 can adsorb harmful gases.

[0020] The outer surface of the upper compartment 25 is hinged with a movable door 7, which facilitates the inspection, maintenance and replacement of the internal components of the upper compartment 25 by the staff. The movable door 7 is equipped with an observation window 71 to observe the working condition inside the upper compartment 25.

[0021] The outer surface of the upper chamber 25 is provided with a pulse assembly 8. The pulse assembly 8 includes a support frame 81 fixedly installed on the outer surface of the upper chamber 25 and a pulse air manifold 82 set on the upper surface of the support frame 81. The outer surface of the pulse air manifold 82 is provided with a nozzle 83. Multiple sets of nozzles 83 are provided. Each set of nozzles 83 is provided with a pulse valve on its outer surface. Each set of nozzles 83 is connected to the interior of the upper chamber 25. When the dust accumulated on the outer surface of the medium-efficiency filter plate 251 reaches a certain amount, the compressed air in the pulse air manifold 82 is injected into the upper chamber 25 through the nozzles 83 and the pulse valve, causing the medium-efficiency filter plate 251 to expand and shake instantly, peeling off the attached dust.

[0022] The inner wall of pipe 23 is equipped with a concentration detection sensor, which is connected to the signal of the machine side box 5 to monitor the dust removal effect in real time, ensuring that the dust concentration in the warehouse is controlled within the range of 5.2-5.5 mg / m³, ensuring that the discharged gas meets environmental protection requirements, and at the same time, the operating status of the equipment can be adjusted in a timely manner according to the detection results to improve the operating efficiency and stability of the equipment.

[0023] Working principle: The user controls the opening and closing of the electric regulating valve 43 in the loading area or the stacking area through two sets of machine side boxes 5 respectively. Since the total designed air volume of the corresponding areas of the loading area main pipe 41 and the stacking area main pipe 42 is 90,000 cubic meters / h, it is convenient to switch the dust collection operation between the loading area and the stacking area on site. After the adjustment is in place, the fan 3 is started. The negative pressure suction generated by the fan 3 allows the dust-laden gas generated during the operation to smoothly enter the branch pipe 6 through the dust collection hood 61. At the same time, the air volume of each branch pipe 6 can be flexibly adjusted with the help of the manual regulating valve 62 to ensure that the dust collection effect in different areas reaches the best. Subsequently, the dust-laden gas is collected through the loading area main pipe 41 or the stacking area main pipe 42 and then transported to the dust collection box 2 for purification treatment through the air inlet pipe 4. In addition, the diameter of the main pipe 41 in the loading area is Φ1500mm. When the branch pipe 6 is connected to the main pipe 41 in the loading area, the diameter of the main pipe 41 in the loading area gradually decreases along the airflow direction to Φ1500mm, Φ1200mm, Φ840mm, and Φ660mm. Furthermore, there are 5 sets of dust collection hoods 61 in the loading area. The size of a single dust collection hood 61 is 3000mm×3000mm, and the design airflow of a single dust collection hood 61 is 18000 cubic meters / h. The diameter of the branch pipe 6 is Φ660mm, and the dust collection efficiency in the loading area must be ≥85%. Meanwhile, the diameter of the main pipe 42 in the stockpiling area is Φ1500mm. When the branch pipe 6 is connected to the main pipe 42 in the stockpiling area, the diameter of the main pipe 42 in the stockpiling area gradually decreases along the airflow direction to Φ1500mm, Φ1200mm, Φ840mm, and Φ660mm. There are 6 sets of branch pipes 6 and dust hoods 61 in the stockpiling area. The size of a single dust hood 61 is 1800mm×1800mm, the design air volume of a single dust hood 61 is 15000 cubic meters / h, the diameter of the branch pipe 6 is Φ660mm, and the dust collection efficiency of the stockpiling area must be ≥70%. In addition, dust-laden gas enters the lower chamber 24 through the air inlet 21. Large dust particles are first intercepted by the metal mesh filter plate 241, which plays a preliminary filtering role. After entering the upper chamber 25, medium-efficiency filter plate 251, high-efficiency filter plate 252 and activated carbon adsorption plate 253 are installed in sequence. The medium-efficiency filter plate 251 and high-efficiency filter plate 252 can remove dust, and the activated carbon adsorption plate 253 can adsorb harmful gases. Finally, it is discharged from the air outlet 22. When the dust accumulated on the surface of the medium-efficiency filter plate 251 reaches a certain amount, compressed air in the pulse air manifold 82 is injected into the upper chamber 25 through the nozzle 83 and pulse valve, causing the medium-efficiency filter plate 251 to expand and shake instantly, peeling off the attached dust. The dust removal effect can be monitored in real time by the concentration detection sensor to ensure that the dust concentration in the warehouse is controlled within the range of 5.2-5.5 mg / m³, ensuring that the discharged gas meets environmental protection requirements. At the same time, the operating status of the equipment can be adjusted in a timely manner according to the detection results to improve the operating efficiency and stability of the equipment.Finally, the movable door 7, which is hinged to the outer surface of the upper compartment 25, facilitates the inspection, maintenance and replacement of the internal components of the upper compartment 25 by the staff, and the observation window 71 inside the movable door 7 facilitates observation.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
