Description
Technical Field

[0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with certain properties using various processing methods. The main technologies of metallurgy include pyrometallurgy, hydrometallurgy, and electrometallurgy.
[0003] Metallurgical processes generate large amounts of metal dust, which can lead to pneumoconiosis and pulmonary fibrosis if inhaled for a long time. Heavy metal dust can also enter the human body through the respiratory tract or skin, causing poisoning. Therefore, dust removal devices for metallurgical protection are needed. However, when traditional dust removal devices remove dust from waste gas, uneven airflow distribution leads to low filtration and interception efficiency, causing toxic particles to be discharged with the airflow. This not only pollutes the environment but also easily causes respiratory diseases. In addition, traditional devices require disassembling the entire housing to replace the filter material, which is time-consuming and labor-intensive, increases maintenance costs, reduces maintenance convenience, and further reduces the practicality of the device.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1
[0024] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a dust removal device for metallurgical protection, including a treatment box 1. The inner wall of the treatment box 1 is respectively provided with a flow guiding component 2 and an installation component 3.
[0025] The treatment box 1 serves as the overall structural carrier and forms a sealed treatment space to ensure that the dust-laden gas completes the purification process inside.
[0026] The flow guiding assembly 2 includes a flow guiding box 201 fixedly connected to the inner wall of the processing box 1. A partition 202 is fixedly connected to the inner wall of the processing box 1. A flow guiding hood 203 is fixedly connected to the top of the partition 202. A spiral flow guiding plate 204 is fixedly connected to the inner wall of the flow guiding hood 203. A corrugated flow guiding plate 205 is fixedly connected to the inner wall of the processing box 1. A vent 206 is provided on the inner wall of the corrugated flow guiding plate 205.
[0027] The flow guide box 201 is used to guide the exhaust gas from the intake pipe 5, directly introducing the exhaust gas into the treatment box 1. The partition 202 partially isolates the space of the treatment box 1, so that the exhaust gas can only flow out along the direction of the flow guide hood 203. The spiral flow guide plate 204 forms a spiral airflow channel inside the flow guide hood 203, reducing the airflow velocity. The corrugated flow guide plate 205, with its corrugated structure, can cause the passing airflow to be split and turned at the corrugated concave and convex points, thereby effectively dispersing the airflow, reducing the airflow velocity, and making the airflow more evenly distributed. The spiral flow guide plate 204 has a 45° spiral angle, achieving a balance between centrifugal force and airflow resistance, so that medium-sized dust particles are more effectively dispersed under the action of centrifugal force. The walls of the flow guide hood 203 are easily thrown to enhance the settling effect of medium-sized dust particles. The vent 206 allows gas to penetrate the plate, further reducing wind resistance and distributing airflow evenly. It should also be noted that the vent 206 does not have a filtering effect, but only evenly discharges airflow. Furthermore, the outer surfaces of all components in the flow guide assembly 2 are covered with a polytetrafluoroethylene coating to form a non-stick surface, making it difficult for particles to adhere. It is also resistant to high temperatures and corrosion, and is suitable for non-oxidizing acid and alkali environments. In conjunction with the spiral flow guide plate 204, which has a 45° spiral angle, medium-sized particles are settled and fall into the dust collection box 9. The inner wall of the corrugated flow guide plate 205 has vent 206.
[0028] The mounting assembly 3 includes a mounting plate 301 that is slidably connected to the inner wall of the processing box 1. A U-shaped groove 302 is provided on the inner wall of the processing box 1. A U-shaped block 303 is fixedly connected to the outer side of the mounting plate 301. A mounting post 304 is fixedly connected to the inner wall of the U-shaped block 303. A nut 305 is threadedly connected to the outer side of the mounting post 304.
[0029] Mounting plate 301 supports filter cartridge 13 and slides on U-shaped groove 302 and U-shaped block 303. U-shaped groove 302 and U-shaped block 303 are adapted to guide mounting plate 301 and limit its movement to ensure consistent installation position. Mounting column 304 passes through treatment box 1 for mounting nut 305. When mounting column 304 is installed in the designated position, nut 305 is screwed in to rigidly lock mounting column 304 and prevent mounting plate 301 from shaking during operation. It should be noted that magnets are installed on the inner wall of U-shaped block 303. When mounting plate 301 is installed, U-shaped block 303 is attracted to the inner wall of U-shaped groove 302. Auxiliary nut 305 fixes mounting plate 301 to ensure that mounting plate 301 does not shift. Example 2
[0030] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0031] Specifically, the outer side of the U-shaped block 303 is slidably connected to the inner wall of the U-shaped groove 302, and the inner wall of the nut 305 is threadedly connected to the end of the mounting post 304.
[0032] The mounting post 304 ensures that the mounting plate 301 will not shift during installation, and the nut 305 rigidly locks the mounting post 304.
[0033] Specifically, the inner wall of the flow guide box 201 is fixedly connected to the connecting flange 4, the inner wall of the connecting flange 4 is fixedly connected to the air inlet pipe 5, and a sealing ring is provided between the air inlet pipe 5 and the connecting flange 4.
[0034] The connecting flange 4 and the inlet pipe 5 are connected by bolts, and the gap between the connections is sealed by a sealing ring to ensure the airtightness of the waste gas transmission. The inlet pipe 5 discharges the waste gas from the metallurgical furnace into the treatment box 1 for filtration. It should be noted that the sealing ring between the connecting flange 4 and the inlet pipe 5 is made of high-temperature resistant fluororubber to prevent gas leakage and ensure airtightness. Its temperature resistance is significant, far exceeding the temperature resistance limit of ordinary rubber, and it is also resistant to oil and solvents, avoiding seal failure caused by media corrosion.
[0035] Specifically, a mounting door 6 is installed on one side of the processing box 1, and the inner wall of the mounting door 6 is slidably connected to the outer side of the mounting column 304.
[0036] The mounting door 6 is used to close the treatment box 1, keeping the treatment box 1 in a sealed state at all times. It is guided by the mounting column 304 and locked in position by the nut 305 to prevent displacement.
[0037] Specifically, an observation window 7 is provided on the inner wall of the installation door 6, and a protective plate 8 is fixedly connected to the inner wall of the observation window 7.
[0038] The observation window 7 provides a viewing window for staff to observe the clogging status of the filter cartridge 13. The protective plate 8 monitors the status of the internal filter cartridge 13 in real time while ensuring safety. It should be noted that the material of the protective plate 8 is microcrystalline glass, which provides high strength, high temperature resistance, acid and alkali resistance, and adjustable light transmittance. It can be made into a semi-transparent material and has excellent thermal shock resistance.
[0039] Specifically, the inner wall of the treatment box 1 is slidably connected to a dust collection box 9, and the outer side of the dust collection box 9 is fixedly connected to a handle 10.
[0040] The dust collection box 9 is used to collect and process large dust particles. The handle 10 provides an operating point for the staff, and the dust collection box 9 can be easily pulled out for cleaning through the handle 10. Example 3
[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0042] The inner wall of the mounting plate 301 is fixedly connected to a connecting ring 12, and the inner wall of the connecting ring 12 is fixedly connected to a filter cartridge 13.
[0043] The connecting ring 12 is used to install the filter cartridge 13 onto the mounting plate 301 to ensure the stable operation of the filter cartridge 13. The filter cartridge 13 filters the dust in the exhaust gas, blocking the dust to the outer surface of the filter cartridge 13. The filtered gas is discharged through the inner wall of the filter cartridge 13.
[0044] Specifically, a trapezoidal air outlet 11 is fixedly connected to the inner wall of the treatment box 1, and a dust collection funnel 14 is fixedly connected to the inner wall of the treatment box 1, with the dust collection funnel 14 located directly below the guide box 201.
[0045] The trapezoidal air outlet 11 adopts a gradually narrowing design. The narrow design accelerates the airflow at the outlet by reducing the outlet cross section. This acceleration effect can reduce the residence time of the airflow at the outlet and reduce the turbulence caused by the deceleration of the airflow, thereby reducing energy loss and improving the overall ventilation efficiency. The dust collection funnel 14 is located directly below the guide box 201 and guides the settled dust into the dust collection box 9.
[0046] Specifically, a limiting groove 15 is provided on the inner wall of the processing box 1, and the limiting groove 15 penetrates the inner wall of the installation door 6. A limiting post 16 is slidably connected to the inner wall of the limiting groove 15.
[0047] The limiting groove 15 is used to install the limiting post 16 and passes through the installation door 6. It can assist the nut 305 in limiting the installation door 6. The limiting post 16 is made of high damping alloy, which takes into account both elastic shock absorption and temperature resistance. At the same time, it has friction with the limiting groove 15 when sliding, and a certain external force is required to pull it.
[0048] Specifically, a U-shaped ring 17 is fixedly connected to the bottom of the mounting plate 301, and the U-shaped ring 17 is located in the connection gap between the mounting plate 301 and the processing box 1.
[0049] U-shaped ring 17 is used to seal the connection gap between mounting plate 301 and treatment box 1, and to fit tightly to prevent gas leakage and reduce filtration efficiency.
[0050] In use, first connect the air inlet pipe 5 to the guide box 201 via the connecting flange 4. At this time, the dust-laden gas enters the guide box 201 through the air inlet pipe 5. Large dust particles settle by gravity and fall into the dust collection box 9 via the dust collection funnel 14. Small fine dust particles rise with the airflow and are formed into a rotating airflow by the spiral guide plate 204, which slows down the airflow. The airflow is then stratified through the vents 206 of the corrugated guide plate 205, ensuring even airflow through the vents 206. The evenly distributed airflow passes through the filter cartridge 13, improving the filtration effect. The purified gas is discharged through the connecting ring 12 and then through the trapezoidal outlet 11. The status of the filter cartridge 13 can be observed through the observation window 7. When replacement is needed, tighten the screw... Release the limit by removing nut 305, remove the installation door 6, and then pull the installation plate 301. The U-shaped groove 302 slides in conjunction with the U-shaped block 303, and the installation plate 301 is pulled out, pulling the filter cartridge 13 out together. The filter cartridge 13 is then cleaned and maintained. After cleaning and maintenance, the installation plate 301 is installed inside the treatment box 1 by aligning the U-shaped block 303 with the U-shaped groove 302. At this time, the magnet in the U-shaped block 303 is attracted to the U-shaped groove 302, which initially limits the installation plate 301. Then, when the installation post 304 penetrates the treatment box 1, the installation door 6 is aligned with the installation post 304, and the limiting post 16 is installed through the limiting groove 15. Then, the nut 305 is screwed in to rigidly lock the installation door 6, completing the replacement of the filter cartridge 13.
[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
