Description

Technical Field

[0001] This utility model relates to the technical field of cartridge dust collectors, specifically a low-noise cartridge dust collector. Background Technology

[0002] In industrial production, material processing, and dusty work environments, dust pollution not only endangers the health of operators but also poses safety hazards such as explosions, while simultaneously polluting the surrounding environment. Cartridge dust collectors, as highly efficient dust purification equipment, separate dust from gas by filtering dust-laden gases through filter cartridges and have been widely used in various industrial settings.

[0003] Traditional cartridge dust collectors commonly suffer from excessive noise during operation. This is mainly due to their unreasonable exhaust structure, with a relatively simple exhaust path and insignificant diameter variation. This results in significant compression of the airflow during discharge, making it difficult to effectively reduce the flow velocity and thus generating substantial turbulent noise. A new technical solution is proposed to address this issue. Summary of the Invention

[0004] The purpose of this invention is to provide a low-noise cartridge dust collector, which solves the problem mentioned in the background art that the air outlet path of traditional cartridge dust collectors is relatively simple and the diameter change is not significant, resulting in the airflow being greatly compressed during the discharge process, making it difficult to effectively reduce the flow velocity, thus generating a large amount of turbulent noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-noise cartridge dust collector, including a shell, a partition is provided in the center of the inner side of the shell, an air outlet pipe is fixedly connected between the inner sidewalls of the shell above the partition, the air outlet pipe is composed of three pipes with different diameters, a spiral guide plate is fixedly connected to the inner sidewall of the air outlet pipe, and the right end opening of the air outlet pipe is located on the sidewall surface of the shell.

[0006] In this technical solution, an air outlet duct consisting of three sections of pipes with different diameters is set at the air outlet position, and the air outlet path gradually expands, reducing the compression and velocity of the airflow. In addition, a spiral guide plate is set to cleverly guide the originally high-speed and turbulent airflow into a spiral vortex, thereby significantly reducing turbulent noise and greatly improving the noise reduction effect.

[0007] Preferably, an air guide plate is provided on the inner side of the outer shell below the partition plate, and four ventilation slots are opened on the side wall surface of the air guide plate. Four insertion ports are opened on the outer shell surface corresponding to the ventilation slots, and filter cartridge bodies are inserted into the insertion ports and the inner side of the ventilation slots.

[0008] Preferably, a fixing frame is fixedly connected between the air guide plate and the inner side wall of the outer shell, the fixing frame is fixedly connected to a plurality of jet pipes, and the jet pipes are connected to the air outlet of a pulse valve installed on the outer side of the outer shell.

[0009] Preferably, a connecting pipe is fixedly connected between the top surface of the partition and the air outlet pipe. The upper and lower ends of the connecting pipe are respectively connected to the air outlet pipe and the space below the partition. A motor is fixedly connected to the bottom surface of the air guide plate directly below the connecting pipe. The tail end of the drive shaft of the motor is connected to the air guide impeller. The air guide impeller is located inside the connecting pipe.

[0010] Preferably, a soft pad is fixedly connected to the inner wall of the right end opening of the air outlet pipe, and rubber rings are fixedly connected to the inner walls of the ventilation slot and the inlet.

[0011] Preferably, an air inlet is provided on the outer surface of the housing above the socket, and a mounting groove is provided on the side wall of the housing above the air inlet, with the motor located inside the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model sets up an air outlet pipe consisting of three sections of pipes with different diameters at the air outlet position, so that the air outlet path gradually expands, reducing the compression and velocity of the airflow. In addition, a spiral guide plate is set up to cleverly guide the originally high-speed and turbulent airflow into a spiral vortex, thereby significantly reducing turbulent noise and greatly improving the noise reduction effect.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A low-noise cartridge dust collector, see Figures 1 to 3 The device includes an outer shell 1, with a partition 6 located in the center of the inner side of the outer shell 1. An air outlet duct 10 is fixedly connected between the inner walls of the outer shell 1 above the partition 6. The air outlet duct 10 consists of three sections of pipes with different diameters. A spiral guide plate 11 is fixedly connected to the inner wall of the air outlet duct 10. The right end opening of the air outlet duct 10 is located on the side wall surface of the outer shell 1. During the air outlet process, the airflow enters the gradually widening air outlet duct 10, thus reducing the compression and velocity of the airflow. Furthermore, the spiral guide plate 11 guides the high-speed airflow into a spiral vortex, thereby reducing turbulent noise and improving the noise reduction effect. A soft pad 12 is fixedly connected to the inner wall of the right end opening of the air outlet duct 10. The soft pad 12 can reduce the impact and friction of the airflow on the edge of the opening of the air outlet duct 10, thereby reducing noise.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, a fixing frame 4 is fixedly connected between the air guide plate 3 and the inner wall of the outer shell 1. The fixing frame 4 is fixedly connected to several jet pipes 5. The jet pipes 5 are connected to the air outlet of the pulse valve 501 installed on the outside of the outer shell 1. The thickness of the dust layer on the surface of the filter cartridge body 2 gradually increases. When the resistance reaches a certain specified value, dust removal is performed. At this time, the PLC program controls the pulse valve 501 to open. The compressed air expands rapidly in a short time and rushes into the jet pipes 5. Then it is sprayed out onto the surface of the filter cartridge body 2, causing the filter cartridge body 2 to vibrate. The dust adhering to the outer surface of the filter cartridge body 2 is impacted down. The jet pipes 5 are designed in a ring shape, which disperses the pulse airflow into annular jets in multiple directions. The graded pulse reduces the instantaneous impact force. The diffuser makes the airflow evenly cover the surface of the filter cartridge, avoiding local high-pressure impact noise and further improving the noise reduction effect.

[0023] Specifically, such as Figure 2 and Figure 3As shown, an air guide plate 3 is provided on the inner side of the outer shell 1 below the partition plate 6. Four ventilation slots 301 are opened on the side wall surface of the air guide plate 3. Four inlets 102 are opened on the surface of the outer shell 1 corresponding to the ventilation slots 301. Filter cartridge bodies 2 are inserted into the inner side of the inlets 102 and the ventilation slots 301. At the same time, rubber rings 302 are fixedly connected to the inner walls of the ventilation slots 301 and the inlets 102. Four filter cartridge bodies 2 can be inserted into the inner side of the outer shell 1, thereby improving the filtration effect. When the high-speed airflow passes through the filter cartridge bodies 2, some vibration will be generated. Therefore, rubber rings 302 are set on the inner walls of the inlets 102 and the ventilation slots 301 to maintain the seal and provide a certain buffer, thereby reducing collision and noise.

[0024] It is worth noting that, such as Figure 2 and Figure 3 As shown, a connecting pipe 9 is fixedly connected between the top surface of the partition 6 and the air outlet pipe 10. The upper and lower ends of the connecting pipe 9 are connected to the air outlet pipe 10 and the space below the partition 6, respectively. A motor 8 is fixedly connected to the bottom surface of the air guide plate 3 directly below the connecting pipe 9. The tail end of the drive shaft of the motor 8 is connected to the air guide impeller 801. The air guide impeller 801 is located inside the connecting pipe 9. When the motor 8 starts and drives the air guide impeller 801 to rotate, the rotation process drives the airflow upward, so that the airflow entering the outer shell 1 quickly passes through the filter body 2 and is discharged from the air outlet pipe 10.

[0025] It is worth noting that, such as Figure 1 and Figure 3 As shown, an air inlet 101 is provided on the surface of the outer casing 1 above the socket 102, and a mounting groove 7 is provided on the side wall of the outer casing 1 above the air inlet 101. The motor 8 is located inside the mounting groove 7. The motor 8 can be directly repaired, maintained and replaced through the mounting groove 7 without disassembling the outer casing 1, which is convenient and quick.

[0026] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
