Description

Technical Field

[0001] The invention relates to the technical field of separation devices, in particular to a novel dust reduction device in a pipeline. Background Art

[0002] Dust reduction technology is the core means for controlling dust pollution in industrial production. It separates and collects dust particles suspended in the gas through physical interception, inertial separation or airflow adsorption. Due to the uneven particle size distribution of dust particles, strong adhesion and easy secondary flying, traditional dust reduction devices mostly use circular cross-section pipes with fixed filters or baffle structures inside, and use gravity sedimentation or filtration principles to achieve dust separation.

[0003] The existing technology has significant defects. The air flow in the circular duct is unevenly distributed, which causes dust to easily accumulate locally on the duct wall. The fixed filter is difficult to intercept dust of different particle sizes due to its single aperture, and fine particles can easily penetrate and escape. Dust easily adheres to the surface of the filter or baffle. Especially when the humidity is high, the residual particles will clog the filter holes or get stuck in the mechanical structure, requiring frequent shutdowns for cleaning, which seriously affects production efficiency. The traditional device has a low recovery rate for captured dust, and some microparticles escape with the airflow, causing environmental pollution. The dust adhering to the filter may carry useful materials, resulting in waste of resources. For this reason, we propose a new dust reduction device in the pipeline. Summary of the Invention

[0015] Beneficial effects:

[0016] 1.

The meshing movement of the slide plate along the thread groove can dynamically adjust the position of the filter plate to adapt to different airflow conditions; the limit design of the sealing ring and the slide rod ensures the sealing and low resistance of the filter plate during movement, avoiding dust leakage.

The device realizes the automatic operation of components such as scrapers and auger rods through the linkage of electric telescopic rods, gear sets and synchronous belts, reducing manual intervention. The detergent tank has a built-in blade stirring mechanism to prevent agent deposition. The design of the limit box and sealing strip effectively isolates dust from invading key moving parts, extending the service life. The modular structure supports quick disassembly and maintenance, and the combination of self-cleaning and anti-adhesion functions greatly reduces the frequency of downtime for maintenance.

[0033] Specifically, the fixed plate 71 serves as the supporting base of the cleaning mechanism 7, fixing the motor 72 and the fixed rod 73 to ensure structural stability. The motor 72 provides power to drive the fixed rod 73 to rotate, driving the slide 75 to move along the thread groove 4. The fixed rod 73 transmits the torque of the motor 72, and links the first electric telescopic rod 74 and the slide 75 to achieve axial movement. The first electric telescopic rod 74 adjusts the engagement state of the slide 75 with the thread groove 4 by telescoping to adapt to different airflow conditions. The slide 75 moves in the thread groove 4 through thread engagement, driving the folding brush 76 and the spray head 731 to clean the filter plate 6. After the folding brush 76 is unfolded, it adheres to the surface of the filter plate 6 to remove attached dust and prevent blockage. The spray head 731 sprays cleaning fluid to moisten the dust, suppress secondary dust and maintain the permeability of the filter plate.

[0034] In this embodiment, the outer side of the first electric telescopic rod 74 is fixedly connected to the detergent tank 732 through a sleeve, the inner side of the detergent tank 732 is slidably connected to the discharge straight pipe 77, the upper end of the discharge straight pipe 77 is fixedly connected to the spray head 79, the outer side of the spray head 79 is fixedly connected to the cleaning plate 710, one side of the cleaning plate 710 is fixedly connected to the slide plate 75, and the lower end of the discharge straight pipe 77 is fixedly connected to the discharge hose 78.

[0035] Specifically, the detergent tank 732 stores detergent and supplies liquid to the spray head 79 through the discharge straight pipe 77 and the discharge hose 78. The discharge straight pipe 77 slides up and down when the slide 75 moves, driving the tooth plate 711 to drive the first gear 712 to rotate. The spray head 79 sprays the detergent evenly onto the thread groove 4 to prevent particle residue.

One side of the fixed bracket 713 is fixedly connected to the detergent tank 732, and the front and rear ends of the first gear 712 are fixedly connected to the blade 714 through a rotating shaft.

[0037] Specifically, the tooth plate 711 is engaged with the first gear 712, converting the linear motion of the discharge straight pipe 77 into gear rotation. The first gear 712 drives the blade 714 to rotate, stirring the liquid in the detergent tank 732 to avoid sedimentation. The blade 714 mixes the detergent by rotation to ensure uniform concentration of the agent. The limit plate 715 limits the stroke of the tooth plate 711 to prevent gear dislocation.

[0038] In this embodiment, a second electric telescopic rod 716 is installed at the other end of the fixed rod 73, and a mounting bracket 717 is fixedly connected to the outer side of the second electric telescopic rod 716. An air pump 718 is installed at the upper end of the mounting bracket 717. The input port of the air pump 718 is fixedly connected to an air intake pipe 720. The air intake pipe 720 is L-shaped. The other end of the air intake pipe 720 is in contact with the filter plate 6. The air pump 718 is provided with two sets of symmetrical output ports. The output port of the air pump 718 is fixedly connected to an exhaust hose 719. The exhaust hose 719 is made of soft rubber.

[0039] Specifically, the second electric telescopic rod 716 adjusts the position of the mounting bracket 717 and controls the coverage range of the exhaust hose 719. The air pump 718 generates airflow to drive the exhaust hose 719 to swing, knocking on the pipe wall to remove ash; at the same time, the filtered gas is extracted to form a reverse airflow to absorb the escaped dust. The exhaust hose 719 uses the swinging of the hose to generate physical impact force to peel off the dust attached to the pipe wall. The L-shaped design of the air inlet pipe 720 fits the filter plate 6 to extract clean gas to generate a reverse airflow.

[0040] In this embodiment, a circular plate 721 is fixedly connected to one side of the mounting bracket 717, and a limiting groove is provided on one side of the circular plate 721. A first connecting rod 722 is slidably connected to one side of the circular plate 721 through the limiting groove. The other end of the first connecting rod 722 is rotatably connected to the connecting bracket 723. The inner side of the connecting bracket 723 is rotatably connected to the third electric telescopic rod 724 through a rotating shaft. The output shaft of the third electric telescopic rod 724 is rotatably connected to a wind shield 725 through a rotating shaft. The outer side of the wind shield 725 is rotatably connected to the inner side of the separation tube 1 near the top through a rotating shaft, and the lower end of the wind shield 725 is fixedly connected to a serrated clip 726.

[0041] Specifically, the annular plate 721 constrains the sliding trajectory of the first connecting rod 722 through the limiting groove to ensure the stability of the angle adjustment of the wind shield 725. The third electric telescopic rod 724 drives the wind shield 725 to rotate, adjusts the cross-sectional area and direction of the airflow, and the wind shield 725 uses the serrated clip 726 to enhance the airflow disturbance, causing large particles of dust to settle after inertial collision.

[0042] In this embodiment, the cleaning mechanism 7 also includes a sliding rod 727 fixedly connected to the sealing ring 5. The sliding rod 727 is T-shaped. The outer side of the sliding rod 727 is slidably connected to the limit box 728. The lower end of the limit box 728 is fixedly connected to the separation tube 1. The outer side of the limit box 728 is fixedly connected with two groups of symmetrical rollers 729. The rollers 729 are slidably connected to the inner side of the limit box 728. The lower end of the limit box 728 is fixedly connected with two groups of symmetrical sealing strips 730. The sealing strips 730 are made of soft rubber material.

[0043] Specifically, the T-shaped design of the slide rod 727 connects the sealing ring 5 to transmit the moving force of the filter plate 6. The roller 729 rolls in the limit box 728 to reduce the movement resistance of the slide rod 727. The rubber material of the sealing strip 730 isolates dust from invading the limit box 728 and protects the internal moving parts.

[0044] In this embodiment, one end of the second gear 81 is fixedly connected to the output shaft of the second electric telescopic rod 716, the outer side of the second gear 81 is rotatably connected to the synchronous belt 82, the inner side of the synchronous belt 82 is rotatably connected to the third gear 83, one end of the third gear 83 is rotatably connected to the collecting box 84 through the rotating shaft, the upper end of the collecting box 84 is fixedly connected to the separation tube 1, the inner side of the collecting box 84 is rotatably connected to the auger rod 85, one end of the auger rod 85 is fixedly connected to the third gear 83, and the lower end of the collecting box 84 is fixedly connected to two groups of symmetrical collection tanks 86.

[0045] Specifically, the second gear 81 drives the third gear 83 through the synchronous belt 82, and the auger rod 85 is linked to rotate the auger rod 85. The spiral conveying structure pushes the dust in the collection box 84 to the collection tank 86, which facilitates the centralized recovery and treatment of the dust.

[0046] In this embodiment, the scraping mechanism 9 includes a fourth electric telescopic rod 91 fixedly connected to the second gear 81, and the output shaft of the fourth electric telescopic rod 91 is rotatably connected to two sets of symmetrical second connecting plates 92, and one side of the second connecting plate 92 is fixedly connected to a second connecting rod 93, and the same end of the two sets of second connecting rods 93 is commonly fixedly connected to a scraper 94, and a brush is provided on the outside of the scraper 94, and the outside of the scraper 94 is in contact with the separation tube 1.

[0047] Specifically, the fourth electric telescopic rod 91 drives the second connecting plate 92 and the second connecting rod 93 to move, adjusts the position of the scraper 94, and the brush on the outer side of the scraper 94 fits the connection between the separation tube 1 and the air inlet duct 2 to remove dust and maintain smooth airflow.

[0048] The working principle is that when in use, the dust-laden air flow enters the elliptical separation tube 1 through the air inlet duct 2 and is first preliminarily filtered by the filter plate 6. The motor 72 installed on one side of the fixed plate 71 is started. The output shaft of the motor 72 drives the fixed rod 73 to rotate, driving the first electric telescopic rod 74 and the slide plate 75 to rotate synchronously. When the slide plate 75 moves, the foldable brush 76 is unfolded so that it always fits the surface of the filter plate 6, and removes the attached dust by rotation. The spray head 731 on the slide plate 75 sprays the cleaning liquid synchronously to prevent the dust from flying again and maintain the permeability of the filter plate 6. The slide plate 75 moves along the thread groove 4 on the inner wall of the separation tube 1 and maintains the meshing state with the thread groove 4 through telescopic adjustment. When the slide plate 75 rotates, it drives the filter plate 6 to move on the inner side of the separation tube 1 according to the size of the air flow. When the filter plate 6 moves, the sealing ring 5 ensures the sealing with the inner wall of the separation tube 1. The slide bar 727 slides in the limit box 728 through the roller 729 to reduce the movement resistance The cleaning agent in the cleaning agent tank 732 is sprayed out through the discharge straight pipe 77 and the discharge hose 78 to keep the thread groove 4 clean. When the first electric telescopic rod 74 is extended, the cleaning plate 710 pushes the discharge straight pipe 77 upward, drives the first gear 712 to rotate in the fixed bracket 713 through the tooth plate 711, drives the blade 714 to rotate, stirs the cleaning agent in the cleaning agent tank 732 to avoid deposition, and the limit plate 715 prevents the tooth plate 711 from being misaligned with the first gear 712. The discharge hose 78 is designed to keep the normal spraying of the spray head 79 when the discharge straight pipe 77 moves.

[0049] The air pump 718 is started, and its output air flow is swung through the exhaust hose 719 and knocks against the inner wall of the separation tube 1, thereby using the air flow and foreign objects to hit and clean the ash on the inner wall of the separation tube 1. The air pump 718 extracts the filtered clean air through the air inlet pipe 720. The power of the air pump 718 is controlled to form a slight reverse airflow on the other side of the filter plate 6, which re-adsorbs the escaping dust onto the surface of the filter plate 6. When the second electric telescopic rod 716 rotates, it drives the mounting bracket 717 to move, so that the mounting bracket 717 drives the exhaust hose 719 to fully clean the inner wall of the separation tube 1;

[0050] When the filter plate 6 moves, the first connecting rod 722 drives the connecting bracket 723, the connecting bracket 723 drives the third electric telescopic rod 724, and the third electric telescopic rod 724 drives the wind shield 725. When the mounting bracket 717 is in rotation, the circular limiting groove design of the annular plate 721 is driven to maintain the connection with the first connecting rod 722. The third electric telescopic rod 724 is started to drive the wind shield 725 to adjust the angle in the separation tube 1, thereby controlling the size of the airflow. By utilizing the inertia of the airflow, large particles of dust collide with the wind shield 725 and fall directly into the auger rod 85. The serrated clip 726 is used to enhance the airflow disturbance and dust separation effect.

[0051] After the dust is cleaned, it is collected downward through the elliptical design of the air inlet duct 2. The second electric telescopic rod 716 drives the second gear 81 to rotate, which drives the third gear 83 and the auger rod 85 to rotate through the synchronous belt 82, and the dust in the collection box 84 is transported to the collection tank 86.

[0052] When the second gear 81 rotates, it drives the fourth electric telescopic rod 91 to rotate. The output shaft of the fourth electric telescopic rod 91 drives the second connecting plate 92 to move. The second connecting plate 92 drives the second connecting rod 93 to move, so that the scraper 94 pushes the dust around the connection between the air inlet duct 2 and the separation tube 1 into the separation tube 1, thereby maintaining smooth airflow between the separation tube 1 and the air inlet duct 2.

[0053] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
