Description

Technical Field

[0001] This utility model relates to the technical field of dust treatment equipment, and in particular to a dust removal device. Background Technology

[0002] In industrial production and material handling, dust and volatile organic compound (VOC) emissions can easily cause air pollution and may also lead to equipment blockage and health hazards. Existing dust removal devices mostly rely on a single filtration structure, which suffers from insufficient filtration precision and poor odor removal. Furthermore, the filters are prone to dust accumulation and blockage after long-term use, requiring manual disassembly and cleaning, which is cumbersome and affects operational efficiency. To address these pain points, there is an urgent need to develop a dust removal device that integrates multi-stage filtration, automatic cleaning functions, and convenient maintenance. This device should achieve efficient interception of dust particles of different sizes and odor purification, while reducing filter cleaning costs and ensuring continuous and stable equipment operation.

[0003] The existing patent document CN220370732U discloses a dust removal device, including a filter box. The filter box has a top cover on its upper surface, and a fixing spring is fixedly connected to the lower surface of the top cover. One end of the fixing spring is fixedly connected to a connecting block. The connecting block has a slot inside, and a protrusion is slidably connected to the inner wall of the slot. A first filter screen is fixedly connected to the inner wall of the protrusion. A second filter screen is connected inside the first filter screen. A first vent pipe is fixedly connected to one side of the outer wall of the filter box.

[0004] However, due to the lack of a convenient filter cleaning device in actual use, the device needs to be disassembled to remove the filter for cleaning, which is inconvenient and affects the continuity of the device's operation. Therefore, we propose a dust removal device that solves the problem of inconvenient filter cleaning, improves the ease of use, shortens downtime, and ensures continuous operation. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal device that solves the problem of inconvenient filter cleaning in existing devices.

[0006] To achieve the above objectives, this utility model provides a dust removal device, including a processing box. A filtration mechanism and an auxiliary cleaning mechanism are fixedly installed inside the processing box. The filtration mechanism includes a coarse filter, a fine filter, and an activated carbon filter. The coarse filter and the fine filter are provided with a limiting ring at their center. A dust suction port is opened at one end of the processing box, and two dust collection hoppers are opened on its bottom side. The coarse filter and the fine filter are respectively fixedly installed on the inner wall of the processing box above the two dust collection hoppers.

[0007] The auxiliary cleaning mechanism includes a rotating shaft, a drive motor, and a rotating rod. The rotating shaft passes through a limiting ring and is rotatably connected to the limiting ring via a bearing. The rotating rod has bristles fixed on the side near the coarse and fine filter screens.

[0008] The processing box has an end cover fixedly installed at the end away from the dust inlet. The drive motor is fixedly installed on the outside of the end cover. The output end of the drive motor is fixedly connected to one end of the rotating shaft through a coupling. The rotating rods are arranged in pairs and symmetrically fixed on the outside of the rotating shaft.

[0009] The filtration mechanism further includes an exhaust port and a dust pump. The exhaust port is connected to the input end of the dust pump through a pipe. A flange connection end is provided at the lower end of the exhaust port. A slot communicating with the inside of the processing box is opened on the upper side of the end away from the dust port. The upper end of the slot is fixed to the flange connection end by bolts. An annular gasket groove is opened on the inner wall of the upper end of the slot. The activated carbon filter is installed inside the annular gasket groove. A sealing gasket is fixedly installed between the upper end of the slot and the flange connection end.

[0010] The processing box has four support columns symmetrically welded to the top surface near the end cover. A support platform is fixedly installed on the top of the support columns. The dust pump is fixedly installed on the top surface of the support platform. A PLC controller is embedded in the outer wall of the processing box. The PLC controller controls the start and stop of the dust pump and the drive motor.

[0011] The dust suction port is fixedly installed with a protective net, the dust collection hopper is threaded with a cover at the lower end, and both the coarse and fine filter screens are equipped with reinforcing rods. One end of the reinforcing rod is fixedly welded to the inner wall of the mesh frame, and the other end is welded to the limiting ring.

[0012] This utility model discloses a dust removal device that uses a dust pump to draw dust from the suction port into a processing chamber. Inside the chamber, the dust is first filtered by a coarse filter for large-particle impurities, then by a fine filter for small-particle impurities, and finally by an activated carbon filter to adsorb volatile organic compounds or odors before being discharged from the dust pump output. This achieves a multi-stage air dust removal effect. A drive motor rotates a shaft, which in turn rotates a rod, causing bristles to repeatedly brush along the filter surface, dislodging impurities into a dust collection hopper below for centralized processing. This filter cleaning method is not only convenient and quick, but also eliminates the need for disassembly, effectively shortening downtime and improving the device's continuous operation.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The first embodiment of this application is as follows: Please see Figure 1 - Figure 3This embodiment of a dust removal device includes a processing box 1. A filter mechanism 2 and an auxiliary cleaning mechanism 3 are fixedly installed inside the processing box 1. The filter mechanism 2 includes a coarse filter 4, a fine filter 5, and an activated carbon filter 6. A limiting ring 7 is provided at the center of the coarse filter 4 and the fine filter 5. A dust suction port 8 is provided at one end of the processing box 1, and two dust collection hoppers 9 are provided on its bottom side. The coarse filter 4 and the fine filter 5 are respectively fixedly installed on the inner wall of the processing box 1 above the two dust collection hoppers 9. The filter mechanism 2 also includes a suction port 16 and a dust pump 17. The suction port 16 is connected to the input end of the dust pump 17 through a pipe 18. A flange connection end 19 is provided at the lower end of the suction port 16. A slot 20 communicating with the interior of the processing box 1 is provided on the upper side of the end of the processing box 1 away from the suction port 8. The upper end of the slot 20 is fixed to the flange connection end 19 by bolts. A sealing gasket is fixedly installed between the upper end of the slot 20 and the flange connection end 19. An annular gasket groove 21 is opened on the inner wall of the upper end of the slot 20, and the activated carbon filter 6 is clamped inside the annular gasket groove 21. Four support columns 22 are symmetrically welded to the top surface of the end of the treatment box 1 near the end cover 15. A support platform 23 is fixedly installed on the top of the support columns 22. The dust pump 17 is fixedly installed on the top surface of the support platform 23. A PLC controller 24 is embedded in the outer wall of the treatment box 1. A protective net 25 is fixedly installed inside the dust suction port 8, and a cover 26 is threadedly installed at the lower end of the dust collection hopper 9.

[0018] With the above scheme, during use, the dust pump 17 is started by the PLC controller 24, creating negative pressure in the processing box 1. Dust-laden gas enters the box through the suction port 8. First, large dust particles are intercepted by the coarse filter 4, and then fine dust particles are filtered by the fine filter 5. Finally, the gas passes through the activated carbon filter 6 to adsorb odors and fine dust, and after purification, it is discharged through the pipe 18 by the dust pump 17, achieving an air purification effect. The support column 22 and the support platform 23 provide stable support for the dust pump 17, and the sealing gasket at the flange connection ensures airtightness. The activated carbon filter 6 is detachably installed in the annular gasket groove 21 opened on the inner wall of the upper end of the slot 20, and is connected to the suction port 8 through the flange joint, which facilitates the subsequent replacement of the activated carbon filter 6 and improves the ease of use.

[0019] The second embodiment of this application is as follows: Please see Figure 1 - Figure 4Based on the first embodiment, the dust removal device of this embodiment further includes a rotating shaft 10, a drive motor 11, and rotating rods 12. The rotating shaft 10 passes through a limiting ring 7 and is rotatably connected to the limiting ring 7 via a bearing 13. Brush bristles 14 are fixed on the side of the rotating rod 12 near the coarse filter 4 and the fine filter 5. An end cover 15 is fixedly installed on the end of the processing box 1 away from the dust inlet 8. The drive motor 11 is fixedly installed on the outside of the end cover 15. The output end of the drive motor 11 is fixedly connected to one end of the rotating shaft 10 via a coupling. The rotating rods 12 are arranged in pairs and symmetrically fixed on the outside of the rotating shaft 10. Both the coarse filter 4 and the fine filter 5 are provided with reinforcing rods 27. One end of the reinforcing rod 27 is fixedly welded to the inner wall of the mesh frame 28, and the other end is welded to the limiting ring 7.

[0020] With the above solution, during use, the drive motor 11 is activated via the PLC controller 24. The drive motor 11 drives the rotating shaft 10 to rotate via the coupling, which in turn drives the symmetrically fixed rotating rods 12 and brushes 14 on the rotating shaft 10 to brush the filter screen, brushing the impurities on the filter screen surface into the dust collection hopper 9 below. Finally, the accumulated impurities can be removed by opening the cover 26, easily achieving the filter screen cleaning effect, avoiding filter screen clogging, reducing the frequency of disassembly and maintenance, and ensuring the normal operation of the device. The reinforcing rod 27 installed on the filter screen can fix the limiting ring 7, providing stable support for the rotational movement of the rotating shaft 10, thus ensuring the durability and operational stability of the device.

[0021] Working principle: First, the dust pump 17 is activated via the PLC controller 24, drawing dust from the suction port 8 into the processing chamber 1. Inside the chamber, the dust is first filtered by the coarse filter 4 for large particles, then by the fine filter 5 for small particles, and finally by the activated carbon filter 6 for adsorbing volatile organic compounds or odors before being discharged from the output of the dust pump 17, thus achieving air dust removal. After a period of use, to prevent filter clogging and maintain dust removal efficiency, the drive motor 11 can be activated via the PLC controller 24 to rotate the shaft 10, which in turn rotates the rod 12, causing the bristles 14 to repeatedly brush along the filter surface. The brushed-off impurities automatically fall into the dust collection hopper 9 along the inner wall of the processing chamber 1. Operators can periodically clean the dust by opening the cover 26, achieving a quick cleaning of the filter. The activated carbon filter 6 can be cleaned or replaced periodically by opening the exhaust port 16 connected to the flange, making it very convenient to use.

[0022] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
