Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, specifically to a dust collection and treatment device for a zinc alloy smelting furnace. Background Technology

[0002] In modern industrial production, zinc alloys are widely used in automobile manufacturing, electronic equipment, hardware products and other fields due to their good mechanical properties, processing performance and low cost. As a key link in the production process, the quality and efficiency of zinc alloy smelting directly affect the performance and quality of subsequent products. However, during the zinc alloy smelting process, the high temperature causes physical and chemical reactions in the zinc alloy material, which will produce a large amount of dust containing zinc oxide, dust particles and other harmful impurities. This dust will not only seriously pollute the air quality in the production workshop and threaten the health of operators, but also have an adverse impact on the surrounding environment. At the same time, the dust adhering to the surface of the equipment will also affect the normal operation and service life of the equipment and reduce production efficiency. However, existing dust collection devices for zinc alloy smelting furnaces still have some problems in use: Firstly, electrostatic precipitators are generally used for flue gas dust removal in smelting furnaces. However, the maintenance of electrostatic precipitators is relatively complex. Furthermore, if the airflow distribution is uneven during dust removal, the airflow speed in some areas will be too fast, and the dust will not have enough time to be adsorbed before being carried out of the dust collector, thus reducing the dust collection efficiency. Secondly, the dust collection and treatment device lacks an effective dust removal structure. During dust removal, the dust collection components need to be disassembled and cleaned, which increases the downtime of the device and reduces its practicality. Utility Model Content

[0012] 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.

[0013] Example: Figure 1-3 As shown, this utility model provides a dust collection device for a zinc alloy smelting furnace, including a treatment box 1. A sealing plate 4 is movably snapped onto one side of the treatment box 1, and the sealing plate 4 is connected to the treatment box 1 by bolts. The movable snap-fit ​​connection between the sealing plate 4 and the treatment box 1 with the bolts facilitates disassembly and installation. During equipment maintenance and repair of the dust collection assembly 2 and the dust removal assembly 3, the treatment box 1 can be quickly opened. At the same time, the bolt connection ensures the sealing between the sealing plate 4 and the treatment box 1. The lower surface of the treatment box 1 is connected to a dust collection hopper 5. The dust collection hopper 5 can collect the dust filtered from the dust collection assembly 2, and its funnel-shaped structure facilitates the natural sliding and accumulation of dust.

[0014] The lower surface of the ash collection hopper 5 is connected to an ash discharge pipe 7, and the outer surface of the ash discharge pipe 7 is equipped with a control valve 6. The ash discharge pipe 7, in conjunction with the control valve 6, can control the dust discharge as needed. When the dust in the ash collection hopper 5 reaches a certain amount, the control valve 6 can be opened to discharge the dust, thus avoiding excessive dust accumulation that could affect the dust collection effect. One side of the ash collection hopper 5 is connected to an air inlet pipe 8, which provides an entry channel for dust-laden flue gas, allowing the flue gas to smoothly enter the dust collection treatment device from the exhaust port of the zinc alloy smelting furnace. The treatment box 1 is equipped with a dust collection component 2 inside, and a dust removal component 3 is also equipped inside the treatment box 1 to work in conjunction with the dust collection component 2. The dust collection component 2 and the dust removal component 3 work together. The dust collection component 2 is responsible for efficiently filtering the dust in the flue gas, and the dust removal component 3 cleans the dust adhering to the dust collection component 2 in a timely manner, ensuring the continuous and stable operation of the dust collection component 2. The combination of the two greatly improves the dust removal efficiency and practicality of the dust collection treatment device.

[0015] The dust collection assembly 2 includes a mounting plate 26, which is movably engaged inside the processing box 1. The mounting plate 26 and the positioning groove 28 are designed to be easily installed into the processing box 1. The processing box 1 has a positioning groove 28 inside that works with the mounting plate 26. The mounting plate 26 is movably engaged with the positioning groove 28, which also provides precise positioning to ensure the accurate installation position of the mounting plate 26. This lays the foundation for the subsequent installation and stable operation of components such as the dust collection bag body 25, and facilitates disassembly and replacement. The upper surface of the mounting plate 26 has a rectangular array of slots 27, which are movably engaged with the dust collection bag body 25. The movable engagement between the slots 27 and the dust collection bag body 25 facilitates the installation and disassembly of the dust collection bag body 25.

[0016] The slot 27 is magnetically attached to a support frame 24 that works with the dust collection bag body 25. The support frame 24 is located inside the dust collection bag body 25 and is magnetically attached to the slot 27. This provides structural support to the dust collection bag body 25, preventing it from collapsing or deforming under the suction of the fan 22, and ensuring that the dust collection bag body 25 maintains a good filtration shape and space. A support frame 23 is fixedly connected to one side of the processing box 1. A fan 22 is fixedly installed on the upper surface of the dust collection bag body 25. The support frame 23 provides stable support for the fan 22. One side of the fan 22 is connected to an exhaust pipe 21, and one end of the exhaust pipe 21 is connected to the treatment box 1. The fan 22 is connected to the treatment box 1 through the exhaust pipe 21 and can generate suction to draw dust-laden flue gas from the air inlet pipe 8 into the treatment box 1 and make it pass through the dust collection bag body 25 to achieve efficient dust removal. The fan 22 is configured to provide power for the flow of flue gas and ensure the continuity and stability of the dust collection process.

[0017] The dust removal assembly 3 includes a support plate 33, which is fixedly installed on one side of the processing box 1. An air tank 35 is fixedly installed on the upper surface of the support plate 33. The air tank 35 is used to store compressed air and provide an air source for pulse jet cleaning. The stable air source reserve ensures the continuity of the cleaning process. Connecting pipes 34 are provided at equal intervals on the upper surface of the air tank 35. A pulse valve 36 is connected to the top of the connecting pipe 34. The pulse valve 36 can control the instantaneous release of compressed air to realize pulse jet cleaning. An exhaust pipe 31 is connected to one side of the pulse valve 36 and passes through one side of the processing box 1. The exhaust pipe 31 introduces the compressed air released by the pulse valve 36 into the processing box 1.

[0018] The lower surface of the exhaust pipe 31 is connected to jet pipes 32 at equal intervals. The jet pipes 32 are positioned at corresponding positions above the dust collection bag body 25. The jet pipes 32 are evenly spaced above the dust collection bag body 25, which can evenly spray compressed air onto each dust collection bag body 25, so that the impact force generated by the compressed air acts evenly on the surface of the dust collection bag body 25, effectively shaking off the attached dust. The exhaust pipe 31 is fixedly installed inside the treatment box 1, which ensures that the position of the jet pipes 32 is fixed. Dust cleaning can be completed without disassembling the dust collection bag body 25, reducing the downtime of the device and improving the practicality of the dust collection treatment device.

[0019] Working principle: First, when the dust collection device of the zinc alloy smelting furnace is working, the dust-laden flue gas first enters the dust collection hopper 5 through the air inlet pipe 8. The dust collection hopper 5 is funnel-shaped, which allows the larger dust particles in the flue gas to settle initially under the action of gravity, achieving the effect of pre-dust removal and reducing the burden on the subsequent dust collection component 2.

[0020] Next, through the dust collection assembly 2, under the action of the fan 22, the flue gas that has undergone preliminary settling is drawn into the treatment box 1 through the exhaust pipe 21. After entering the treatment box 1, the flue gas enters the dust collection bag body 25. The dust collection bag body 25 is movably engaged in the slot 27. Inside, there is a magnetically engaged support frame 24 in the slot 27. The support frame 24 can prevent the dust collection bag body 25 from collapsing under negative pressure, ensuring its good filtration space.

[0021] When the dust-laden flue gas passes through the dust collection bag body 25, the dust is intercepted on the outer surface of the bag, and the purified gas passes through the bag and is discharged from the other side of the treatment box 1, achieving efficient dust removal.

[0022] As the dust collection process continues, a large amount of dust will adhere to the outer surface of the dust collection bag body 25, at which point the dust removal component 3 will start working.

[0023] When dust removal is required, the control system triggers the pulse valve 36. Compressed air in the air tank 35 enters the pulse valve 36 through the connecting pipe 34, and is sprayed onto the dust collection bag body 25 through the exhaust pipe 31 and the jet pipe 32.

[0024] The jet pipe 32 is positioned above the dust collection bag body 25. The instantaneous impact of compressed air causes the dust collection bag body 25 to vibrate, shaking off the dust adhering to the surface. The dust falls into the dust collection hopper 5, completing the dust removal process. This dust removal method does not require disassembling the dust collection bag body 25, reducing the downtime of the device.

[0025] Finally, when the dust in the dust collection hopper 5 accumulates to a certain amount, the control valve 6 on the outer surface of the dust discharge pipe 7 is opened, and the dust is discharged from the device through the dust discharge pipe 7.

[0026] Meanwhile, the sealing plate 4 is connected to the treatment box 1 by bolts, which can be easily disassembled during equipment maintenance, replacement of the dust collection bag body 25 and other operations, and can ensure the sealing of the inside of the treatment box 1 to prevent the leakage of dust-laden flue gas.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
