Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, and in particular to an integrated machine for dust collection and air purification in a dry powder mixing workshop. Background Technology

[0002] During the dry powder mixing production process, a large amount of suspended dry powder dust will be generated in the workshop. In order to ensure the safety of the production environment and meet the environmental protection emission requirements, the dust needs to be extracted to the purification unit through the air intake pipe for treatment and purification. In existing technologies, air intake pipes need to be laid according to the actual working conditions such as workshop equipment layout and wall distribution. Inevitably, multiple bends (such as 90° bends and 45° bends) are set up to achieve path avoidance. However, the above-mentioned pipe layout has inherent defects: dry powder dust has a certain inertia. At the bend of the pipe, the airflow is forced to change direction due to the constraint of the pipe wall. Due to inertia, the dust particles have difficulty changing their trajectory synchronously and are easy to collide and deposit on the outer pipe wall of the bend. At the same time, the cross-sectional area of ​​the airflow at the bend increases in effect, resulting in a decrease in flow velocity, and the inner side is prone to the formation of vortex zone, which further aggravates the dust retention and accumulation. Dust accumulation at bends in pipes directly affects the operational stability and reliability of the integrated air purification unit. Accumulated dust reduces the effective pipe diameter, increases system pressure drop, leads to insufficient air intake, reduced dust collection efficiency, and causes the fan to operate under overload for extended periods, shortening the lifespan of core components. Currently, pipe design has not developed an effective solution to the aforementioned accumulation problem, severely restricting the operational efficiency and safety of dust collection and purification systems, thus creating limitations.

[0003] To address this, we propose an integrated dust collection and air purification machine for dry powder mixing workshops. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated dust collection and air purification machine for dry powder mixing workshops, overcoming the deficiencies of existing technologies and aiming to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated dust collection and air purification machine for a dry powder mixing workshop, comprising: The system includes a body, an inlet pipe, a connecting pipe, a filter screen, and a fan. The inlet pipe is installed on the body, and the connecting pipe is connected to the inlet pipe. An installation box is fixedly connected to the machine body. A dredging mechanism is installed inside the installation box. The dredging mechanism enters the connecting pipe through the inlet pipe and dredges the dust accumulated at the bends in the connecting pipe.

[0006] Preferably, the unblocking mechanism includes a moving ring, an unblocking block, an unblocking brush, and a mounting block. The moving ring is equipped with a moving wheel and has an annular groove. An annular rack is fixedly connected to the moving ring. The unblocking block is slidably connected in the annular groove. A sliding motor is fixedly connected to the unblocking block. A gear that meshes with the annular rack is fixedly connected to the output end of the sliding motor. A roller motor is installed in the moving wheel for driving. The mounting block is installed on the unblocking block, the unblocking brush is rotatably connected to the mounting block, and an unblocking motor that drives the unblocking brush to rotate is fixedly connected inside the mounting block.

[0007] Preferably, a winding motor is fixedly connected inside the mounting box, and a winding reel is fixedly connected to the output end of the winding motor. A connecting wire is wound on the winding reel, and the connecting wire is connected to the moving ring. The connecting wire supplies power to the electrical components inside the moving ring and the unblocking block.

[0008] Preferably, a push-in block is slidably connected inside the mounting box, a push-in electric push rod is fixedly connected between the push-in block and the mounting box, an electromagnetic coil is fixedly connected to the push-in block, a magnet is fixedly connected to the moving ring, and a fixing rod is fixedly connected to the push-in block, with the fixing rod supporting the moving ring; The inlet pipe has a notch, and an arc-shaped sealing block is slidably connected inside the notch. An electric pull-out push rod is fixedly connected inside the mounting box, and the output end of the electric pull-out push rod is fixedly connected to the arc-shaped sealing block.

[0009] By installing a push block, a moving ring, and a cleaning brush on one side of the inlet pipe, the moving ring enters the inlet pipe through a notch and then enters the connecting pipe. The moving ring moves along the connecting pipe, while the cleaning brush rotates and scrapes the inner wall of the connecting pipe. The cleaning brush then scrapes up the dust accumulated at the bends in the connecting pipe. The accumulated dust passes through the filter screen along with the connecting pipe and the inlet pipe, thus clearing the dust accumulated at the bends in the connecting pipe while the filter screen is in place.

[0010] Preferably, the unblocking block has a telescopic groove, the mounting block is slidably connected in the telescopic groove, a telescopic motor is fixedly connected in the telescopic groove, and the output end of the telescopic motor is fixedly connected to a lead screw that is threadedly engaged with the mounting block.

[0011] Preferably, a sealing shell is fixedly connected to the unblocking block, and the sealing shell covers the annular rack and the annular groove.

[0012] Preferably, inclined blocks are fixedly connected to the outer side of the moving ring at even intervals, and an arc-shaped rod is rotatably connected to the inclined block. After the arc-shaped rod rotates on the inclined block, the top end of the arc-shaped rod moves outward. An L-shaped rod is fixedly connected to the arc-shaped rod, and an electric push rod is spherically hinged between the moving ring and the L-shaped rod.

[0013] Preferably, a caster wheel is rotatably connected to the arc-shaped rod, and a movable wheel is rotatably connected to the caster wheel. A roller motor is installed inside the movable wheel for driving.

[0014] By setting an arc-shaped rod and an inclined block on the moving ring, the end of the arc-shaped rod is tilted outward after rotating along the inclined surface of the inclined block. Therefore, the moving wheel can contact the inner wall of the connecting pipe with a larger diameter, and the mounting block can slide on the unblocking block. Thus, the moving ring of the present invention can move in connecting pipes of different diameters, and the unblocking brush can unblock the dust accumulated in connecting pipes of different diameters.

[0015] The beneficial effects of this invention are: 1. This invention provides a push-in block, a moving ring, and a cleaning brush on one side of the inlet pipe. The moving ring enters the inlet pipe through a notch and then into the connecting pipe. The moving ring moves along the connecting pipe, while the cleaning brush rotates and scrapes the inner wall of the connecting pipe. This cleaning brush removes dust accumulated at the bends in the connecting pipe. The accumulated dust is filtered through a filter screen along with the connecting pipe and the inlet pipe. Therefore, the dust accumulated at the bends in the connecting pipe can be cleared even while the filter screen is filtering the dust.

[0016] 2. The present invention provides an arc-shaped rod and an inclined block on the moving ring, so that the end of the arc-shaped rod tilts outward after rotating along the inclined surface of the inclined block. Therefore, the moving wheel can contact the inner wall of the connecting pipe with a larger diameter, and the mounting block can slide on the unblocking block. Thus, the moving ring of the present invention can move in connecting pipes of different diameters, and the unblocking brush can unblock the dust accumulated in connecting pipes of different diameters.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Refer to the appendix of the instruction manual. Figures 1 to 6 A dust collection and air purification integrated machine for dry powder mixing workshop, comprising: The unit consists of a body 1, an inlet pipe 11, a connecting pipe 12, a filter screen 13, and a fan 14. The inlet pipe 11 is installed on the body 1, and the connecting pipe 12 is connected to the inlet pipe 11. An installation box 15 is fixedly connected to the main body 1. A dredging mechanism is installed inside the installation box 15. The dredging mechanism enters the connecting pipe 12 through the inlet pipe 11 to dredge the dust accumulated at the bend in the connecting pipe 12.

[0021] In this invention, the electrical components are controlled by a controller. The unblocking mechanism includes a moving ring 21, an unblocking block 22, an unblocking brush 23, and a mounting block 24. A moving wheel 25 is mounted on the moving ring 21, and an annular groove 26 is opened on the moving ring 21. An annular rack 27 is fixedly connected to the moving ring 21. The unblocking block 22 is slidably connected in the annular groove 26. A sliding motor 28 is fixedly connected to the unblocking block 22. A gear that meshes with the annular rack 27 is fixedly connected to the output end of the sliding motor 28. A roller motor is installed in the moving wheel 25 for driving. Mounting block 24 is mounted on unblocking block 22, unblocking brush 23 is rotatably connected to mounting block 24, and unblocking motor 29, which drives unblocking brush 23 to rotate, is fixedly connected inside mounting block 24.

[0022] In this invention, a winding motor 4 is fixedly connected inside the mounting box 15, and a winding reel 41 is fixedly connected to the output end of the winding motor 4. A connecting wire 42 is wound on the winding reel 41. The connecting wire 42 is connected to the moving ring 21 and supplies power to the electrical components inside the moving ring 21 and the unblocking block 22.

[0023] In this invention, a push-in block 5 is slidably connected inside the mounting box 15, a push-in electric push rod 51 is fixedly connected between the push-in block 5 and the mounting box 15, an electromagnetic coil 52 is fixedly connected to the push-in block 5, a magnet block 53 is fixedly connected to the moving ring 21, and a fixing rod 8 is fixedly connected to the push-in block 5, which supports the moving ring 21. A notch is provided on the inlet pipe 11, and an arc-shaped sealing block 6 is slidably connected inside the notch. An electric pull-out rod 61 is fixedly connected inside the mounting box 15, and the output end of the electric pull-out rod 61 is fixedly connected to the arc-shaped sealing block 6.

[0024] In this invention, one end of the connecting pipe 12 is connected to the inlet pipe 11, and the other end extends into the dust workshop. The air containing dust in the dust workshop enters the inlet pipe 11 through the connecting pipe 12, and then passes through the inlet pipe 11 and is filtered and purified by the filter screen 13. The dust adheres to the filter screen 13. In this invention, when it is necessary to clear the bends in the connecting pipe 12, the electric push rod 61 is pulled out and the arc-shaped sealing block 6 is pulled upward, exposing the notch on the inlet pipe 11. Then, the electric push rod 51 is pushed in to push the push block 5, causing the push block 5 to move laterally with the moving ring 21, so that the push block 5 and the moving ring 21 enter the notch on the inlet pipe 11. Subsequently, the controller supplies current to the electromagnetic coil 52 inside the push block 5, causing the electromagnetic coil 52 to generate magnetic force, pushing the magnet block 53 on the moving ring 21, so that the magnet block 53 carries the moving ring 21 along the inlet pipe. The notch on 11 enters the inlet pipe 11. Since the push block 5 is laterally slidably connected to the mounting box 15, the push electric push rod 51 pushes the push block 5 laterally. The force between the electromagnetic coil 52 and the magnet 53 acts perpendicularly on the push block 5. However, since the push block 5 is laterally slidably connected to the mounting box 15, the mounting box 15 will apply a reverse force to the push block to cancel out the reaction force between the electromagnetic coil 52 and the magnet 53. Therefore, it will not act laterally on the push electric push rod 51. Therefore, when pushing the moving ring 21, the push block 5 is subjected to a reverse force, and then the arc... The arc-shaped sealing block 6 moves downward to seal the gap. Both the arc-shaped sealing block 6 and the inlet pipe 11 are provided with arc-shaped notches. The connecting wire 42 can move within the two notches, so the connecting wire 42 can move with the moving ring 21. Flexible rubber sheets are provided on the notches. Therefore, when the connecting wire 42 is in the two notches, the flexible rubber sheets are attached to the outer surface of the connecting wire 42, which can prevent dust from entering the mounting box 15 through the notches. The moving wheel 25 on the moving ring 21 moves forward along the inlet pipe 11 under the drive of the roller motor. The moving ring 21 enters the connecting pipe 12. Then, the unblocking motor 29 on the mounting block 24 drives the unblocking brush 23 to rotate, and the sliding motor 28 on the unblocking block 22 drives the corresponding gear to rotate, so that the unblocking block 22, along with the mounting block 24 and the unblocking brush 23, rotates along the annular groove 26, thereby the unblocking brush 23 scrapes the inner wall of the connecting pipe 12. When the moving ring 21 reaches the bend of the connecting pipe 12, the unblocking brush 23 scrapes up the dust accumulated at the bend, so that the accumulated dust enters the inlet pipe 11 with the airflow in the connecting pipe 12, thereby unblocking the dust accumulated at the bend of the connecting pipe 12. After the blockage is cleared, the moving ring 21 returns to the original inlet pipe 11. Then, the arc-shaped blocking block 6 moves upward to expose the gap. The push-in block 5 moves into the gap, and the electromagnetic coil 52 on the push-in block 5 generates a magnetic force in the opposite direction to pull the magnet block 53, causing the moving ring 21 to move toward the push-in block 5 and be supported and fixed by the fixing rod 8. The push-in block 5 and the moving ring 21 return to their original positions. The staff regularly open the installation box 15 to clean the inside of the installation box 15 and the moving ring 21. This invention provides a push-in block 5, a moving ring 21, and a cleaning brush 23 on one side of the inlet pipe 11. The moving ring 21 enters the inlet pipe 11 through a notch and then enters the connecting pipe 12. The moving ring 21 moves along the connecting pipe 12, and the cleaning brush 23 rotates to scrape the inner wall of the connecting pipe 12. The cleaning brush 23 scrapes up the dust accumulated at the bend of the connecting pipe 12. The accumulated dust is filtered by the filter screen 13 along with the connecting pipe and the inlet pipe 11. Therefore, the dust accumulated at the bend of the connecting pipe 12 can be cleared even while the filter screen 13 is filtering.

[0025] Example 2: Based on Example 1, refer to the appendix of the instruction manual. Figures 1 to 6 In this invention, the unblocking block 22 is provided with a telescopic groove 7, the mounting block 24 is slidably connected in the telescopic groove 7, the telescopic motor 71 is fixedly connected in the telescopic groove 7, and the output end of the telescopic motor 71 is fixedly connected to a screw that is threadedly engaged with the mounting block 24.

[0026] In this invention, a sealing shell 81 is fixedly connected to the unblocking block 22, and the sealing shell 81 covers the annular rack 27 and the annular groove 26.

[0027] In this invention, inclined blocks 72 are fixedly connected to the outer side of the moving ring 21 at even intervals. An arc-shaped rod 73 is rotatably connected to the inclined block 72. After the arc-shaped rod 73 rotates on the inclined block 72, the top end of the arc-shaped rod 73 moves outward. An L-shaped rod 74 is fixedly connected to the arc-shaped rod 73. An electric push rod 75 is spherically hinged between the moving ring 21 and the L-shaped rod 74.

[0028] In this invention, a caster wheel 3 is rotatably connected to the arc-shaped rod 73, and a movable wheel 25 is rotatably connected to the caster wheel 3. A roller motor is installed inside the movable wheel 25 for driving.

[0029] In this invention, the telescopic motor 71 on the unblocking block 22 drives the corresponding lead screw to rotate, causing the mounting block 24 to move on the unblocking block 22. As a result, the mounting block 24 moves the unblocking brush 23 away from the moving ring 21, thereby extending the rotation radius of the unblocking brush 23 when it rotates along the annular groove 26. This allows the unblocking brush 23 to unblock pipes with larger diameters. Therefore, when the pipe diameter varies in different sections of the actual workshop due to actual layout requirements, the unblocking range of the unblocking brush 23 can be adapted. A sealing shell 81 is provided on the unblocking block 22. The sealing shell 81 covers the annular rack 27, and the sealing shell 81 can rotate with the rotation of the unblocking block 22. Thus, the sealing shell 81 can prevent dust from affecting the movement of the annular rack 27 and the unblocking block 22. In this invention, an arc-shaped rod 73 is provided on the moving ring 21. When the electric push rod 75 pushes outward to push the L-shaped rod 74, the arc-shaped rod 73 rotates on the inclined block 72. During the rotation, the end of the arc-shaped rod 73 away from the inclined block 72 moves away from the center of the moving ring 21, so that the moving wheel 25 at the end of the arc-shaped rod 73 can contact the inner wall of the connecting pipe with a larger diameter. This allows the moving wheel 25 to drive the moving ring 21 to move in connecting pipes of different diameters. The moving wheel 25 and the arc-shaped rod 73 are connected by a universal wheel 3. When the moving wheel 25 rotates, no matter what angle the arc-shaped rod 73 rotates to, the driving path of the moving wheel 25 can be parallel to the axis of the connecting pipe 12, thereby ensuring the driving effect of the moving wheel 25. The present invention provides an arc-shaped rod 73 and an inclined block 72 on the moving ring 21, so that the end of the arc-shaped rod 73 is inclined outward after rotating along the inclined surface of the inclined block 72. Therefore, the moving wheel 25 can contact the inner wall of the connecting pipe with a larger diameter, and the mounting block 24 can slide on the unblocking block 22. Thus, the moving ring 21 of the present invention can move in the connecting pipe 12 with different diameters, and the unblocking brush 23 can unblock the dust accumulated in the connecting pipe 12 with different diameters.
