Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust removal devices, specifically a central dust collector with an optimized airflow structure. Background Technology
[0002] A central dust collector, also known as a baghouse dust collector or intermediate dust collector, is a dry dust filtration device primarily used for purifying dust-laden gases and recovering materials from high-temperature, high-humidity, corrosive gases and flue gas containing sticky gases. Central dust collectors utilize woven or spun fiber filter media as the filtration medium to capture dust-laden flue gas. Their operating principles include effects such as inertial force, gravity, Brownian diffusion, and sieving.
[0003] Currently, most commonly used central dust collectors directly filter dust-laden gases using bag filters. However, long-term use can easily lead to bag blockage or damage, and dust accumulation inside the equipment. This dust can mix into components such as bearings, affecting equipment operation and air purification efficiency. Furthermore, the lack of airflow guidance means that dust in the gas cannot be completely filtered out. Utility Model Content
[0004] This utility model provides a central dust collector with an airflow optimization structure, which can guide dust-laden gas to better remove internal dust, and also filters large dust particles in the dust-laden gas to prevent large dust particles from clogging the device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a central dust collector with an airflow optimization structure, comprising a housing and a top cover fixedly connected to the top of the housing, characterized in that it further comprises an airflow optimization dust collection component and an airflow filtration component, wherein:
[0006] The airflow optimization dust removal component includes a dust collection box, two dust guide covers are fixedly connected to one side of the dust collection box, and air vents are fixedly connected to one side of the two dust guide covers. Dust guide fans are electrically connected to the inner walls of the two air vents.
[0007] The airflow dust filtration assembly includes air guide pipes, and a solenoid valve is fixedly connected to the top end of each of the multiple air guide pipes.
[0008] As a preferred embodiment of this utility model, the outer wall of the box is fixedly connected with a plurality of fixing rings, and a support plate is fixedly connected to the lower end of the outer wall of the box.
[0009] As a preferred embodiment of this utility model, the bottom end of the support plate is provided with multiple legs, and the top ends of the multiple legs are fixedly connected to limit blocks.
[0010] As a preferred technical solution of this utility model, the outer wall of the mounting frame is also equipped with multiple guide frames, and multiple air guide pipes pass through one side of the outer wall of the box. A connecting pipe is fixedly connected to one side of the multiple air guide pipes, and multiple nozzles are fixedly connected to the bottom end of the multiple connecting pipes. A pressure stabilizing pipe passes through the bottom end of the multiple nozzles.
[0011] As a preferred technical solution of this utility model, the bottom end of each voltage regulator tube is fixedly connected to a frame, and dustproof cloths are fixedly connected to both sides of the outer wall of each frame, and multiple crossbars are fixedly connected to one side of the inner wall of each frame.
[0012] As a preferred embodiment of this utility model, a plurality of connecting frames are fixedly connected to the lower end of the inner wall of the box, and two filter plates are fixedly connected to the bottom of each of the plurality of connecting frames near the center.
[0013] As a preferred embodiment of this utility model, a dust outlet is fixedly connected to the bottom end of the box.
[0014] Compared with the prior art, this utility model provides a central dust collector with an airflow optimization structure, which has the following beneficial effects:
[0015] This invention allows dust-laden gas to enter through the inlet. Sand and other impurities are blocked by the filter plate and slide directly to the outlet for discharge. The remaining dust-laden gas contains finer and lighter impurities and dust. A dust-guiding fan blows air through the gas, guiding and impacting the airflow. The airflow agitates the dust-blocking cloth, causing it to shake continuously and removing surface dust, preventing clogging. Furthermore, since larger dust particles are blocked by the filter plate in advance, the dust-blocking cloth no longer needs to remove large particles. The pores only need to remove small dust particles, resulting in better, more efficient, and faster dust removal. Attached Figure Description

[0022] 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. Example 1
[0023] Please see Figure 1 - Figure 5 This utility model discloses a central dust collector with an airflow optimization structure, including a housing 1 and a top cover 11 fixedly connected to the top of the housing 1. Its characteristic is that it further includes an airflow optimization dust collection component 2 and an airflow filtration component 3, wherein:
[0024] The airflow optimization dust removal component 2 includes a dust collection box 21. Two dust guide hoods 22 are fixedly connected to one side of the dust collection box 21. A wind duct 24 is fixedly connected to one side of the two dust guide hoods 22. A dust guide fan 23 is electrically connected to the inner wall of the two wind ducts 24.
[0025] The airflow dust filter assembly 3 includes an air duct 31, and a solenoid valve 32 is fixedly connected to the top of the multiple air ducts 31.
[0026] Please refer to the attached Figure 1 and Figure 2 Multiple fixing rings 12 are fixedly connected to the outer wall of the box body 1, and a support plate 13 is fixedly connected to the lower end of the outer wall of the box body 1.
[0027] Please refer to the attached Figure 1 and Figure 2 Multiple legs 15 extend through the bottom of the support plate 13, and limit blocks 14 are fixedly connected to the top of the multiple legs 15.
[0028] In this embodiment, the dust-guiding fan 23 blows air to guide and impact the dust-laden gas, allowing it to collide with the dust-blocking cloth 36. This filters out the dust in the gas more quickly, and the airflow also causes the dust-blocking cloth 36 to shake continuously, removing floating dust from its surface and preventing clogging. This makes dust removal more efficient and faster. Example 2
[0029] Based on the above embodiment 1, please refer to the appendix. Figure 1 , Figure 3 , Figure 5 Multiple air ducts 31 pass through one side of the outer wall of the housing 1. A connecting pipe 33 is fixedly connected to one side of the multiple air ducts 31. Multiple nozzles 34 are fixedly connected to the bottom of the multiple connecting pipes 33. A pressure stabilizing pipe 35 passes through the bottom of the multiple nozzles 34. A frame 37 is fixedly connected to the bottom of each pressure stabilizing pipe 35. Dust-proof cloths 36 are fixedly connected to both sides of the outer wall of the multiple frames 37. Multiple crossbars 38 are fixedly connected to one side of the inner wall of the multiple frames 37. Multiple connecting brackets 39 are fixedly connected to the lower end of the inner wall of the housing 1. Two filter plates 310 are fixedly connected to the bottom of each of the multiple connecting brackets 39 near the center. A dust outlet 311 is fixedly connected to the bottom of the housing 1.
[0030] In this embodiment, after the dust-laden gas enters through the air inlet, the connecting frame 39 and the filter plate 310 first remove large particles of dust from the gas. Sand and other debris are blocked by the filter plate 310 and slide directly to the dust outlet 311 for discharge. The remaining dust-laden gas contains finer and lighter impurities, which allows the dust-laden gas to collide with the dust-blocking cloth 36, filtering out the dust in the gas more quickly. The dust-blocking cloth 36 is also blown by the wind, causing it to shake continuously and remove floating dust from its surface, preventing clogging.
[0031] The working principle and usage process of this utility model are as follows: After the dust-laden gas enters through the air inlet, it passes through the connecting frame 39 and the filter plate 310. First, the large particles of impurities in the dust-laden gas are initially removed. Sand and other debris are blocked by the filter plate 310 and slide directly to the dust outlet 311 for discharge. The remaining impurities and dust in the dust-laden gas are relatively small and light. The dust guide fan 23 blows air through the dust-laden gas, which guides and impacts the airflow, allowing the dust-laden gas to collide with the dust-blocking cloth 36. This filters out the dust in the dust-laden gas more quickly. The airflow also blows the dust-blocking cloth 36, causing it to shake continuously and remove floating dust from its surface, preventing the dust-blocking cloth 36 from becoming clogged, thus making the dust removal more efficient and faster.
