Description
Technical Field
[0001] This utility model relates to the technical field of filter production process, and in particular to a dust removal device for filter production. Background Technology
[0002] A filter is a device used to filter solid particles or impurities in liquids. Its main purpose is to separate unwanted substances from fluids to improve their purity or cleanliness. Filters play an important role in various industrial, medical, environmental, and daily life applications, helping to ensure the cleanliness, safety, and reliability of fluids. During the production process, filter products typically require the removal of dust particles adhering to the surface before powder coating to improve surface quality. Powder coating utilizes the principle of electrostatic adsorption to evenly spray plastic powder onto the filter surface, which is then cured at high temperature to form a protective film. If dust particles are present on the filter surface, they will hinder the direct contact between the plastic powder and the filter substrate, resulting in reduced adhesion between the powder coating layer and the substrate. For example, in the production of automotive engine filters, if surface dust is not thoroughly removed, the powder coating layer may gradually peel off during engine operation due to vibration and temperature changes, affecting the filter's service life and filtration efficiency.
[0003] Existing dust removal devices used in filter production involve passing the product through multiple dust blowing stations on a conveyor belt. Each station is equipped with spray guns of different angles and pressures to thoroughly blow dust off the product. However, the dust blowing process on the conveyor belt causes the product to shake or shift, and the dust cannot be collected in time and will adhere to the conveyor belt. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] A dust removal device for filter production includes a conveying assembly 1. The conveying assembly 1 includes a frame body 11 and a conveyor belt 12 rotatably installed inside the frame body 11. Dust blocking assemblies 2 are fixedly installed on both sides of the frame body 11. A limiting device 3 for restricting filters is fixedly installed inside the dust blocking assembly 2. An upper dust blowing assembly 4 is fixedly installed on the top wall of the limiting device 3. Side dust blowing assemblies 5 are symmetrically fixedly installed on both sides of the dust blocking assembly 2. A dust collection assembly 6 is fixedly installed below the limiting device 3 and at the bottom of the conveyor belt 12. The limiting device 3 includes a support base 31, a support shaft 32, a hand crank 33, and a rolling assembly 34. The support base 31 is fixedly installed on the upper part of the frame body 11. Shaft 32 is rotatably mounted on both sides of the upper part of support base 31. Two sets of hand cranks 33 are sleeved and mounted in the middle of support shaft 32. Two sets of rolling components 34 are symmetrically rotatably mounted on the bottom of support base 31. Rolling component 34 includes connecting plate 341, intermediate shaft 342, bearing seat 343, rotating shaft 344 and roller 345. Two sets of connecting plates 341 are symmetrically mounted on both sides of the support part of support base 31. Intermediate shaft 342 is inserted between connecting plates 341. Bearing seat 343 is sleeved and mounted on the top of intermediate shaft 342 and fixedly mounted to the outer wall of support part of support base 31. Rotating shaft 344 is rotatably mounted on the outer end of connecting plate 341. Roller 345 is rotatably mounted on the other outer end of connecting plate 341.
[0021] In this embodiment, the filter is placed on the conveyor belt 12 and enters the working area of the dust removal device. The limiting device 3, consisting of the support shaft 32, hand crank 33, and rolling assembly 34, begins to function. By manually operating the hand crank 33, the position of the support shaft 32 is adjusted, causing the roller 345 of the rolling assembly 34 to contact the filter. The roller 345 is connected to the support base 31 via the rotating shaft 344 and the connecting plate 341. As the filter passes by, the roller 345 rotates with the movement of the filter, which not only limits the displacement of the filter but also avoids scratching the surface of the filter. The filter moves on the conveyor belt 12. When the filter reaches below the limiting device 3, the upper dust blowing assembly 4 is activated. The upper dust blowing assembly 4 typically consists of high-pressure nozzles and an air source. The nozzles are aimed at the upper surface of the filter, using high-pressure airflow to blow away dust particles from the upper surface of the filter. Simultaneously, as the filter passes the upper dust blowing assembly 4, the side dust blowing assemblies 5 on both sides of the dust blocking assembly 2 also begin to operate. The side dust blowing assemblies 5, also consisting of high-pressure nozzles and an air source, blow dust from both sides of the filter, ensuring that dust particles on the sides of the filter are also effectively removed. The blown-off dust particles fall under gravity and enter the dust collection assembly 6 located at the bottom of the conveyor belt 12. Component 6 typically consists of a dust collection box and a dust collection device. The dust collection device generates negative pressure to suck dust particles into the dust collection box, preventing dust from re-adhering to the filter or conveyor belt 12. After dust removal, the filter continues to move with the conveyor belt 12, leaving the dust collection device and entering the next production process. Through the synergistic action of the upper dust blowing assembly 4 and the side dust blowing assembly 5, dust particles on the filter surface are thoroughly removed, improving the surface quality of the filter and providing a good foundation for the subsequent powder coating process. The cleaner filter surface after dust removal allows the plastic powder to better contact the filter substrate, improving the powder coating effect. The adhesion between the plastic layer and the substrate reduces the risk of the powder coating peeling off. The dust collection component 6 collects the blown-off dust particles in a timely manner, preventing dust from re-adhering to the filter or conveyor belt 12, avoiding secondary pollution and improving the cleanliness of the production environment. The limiting device 3, through the design of the hand crank 33 and the rolling component 34, can flexibly adjust the limiting force on the filter, adapting to filter products of different shapes and sizes, improving the versatility and adaptability of the device. The automated operation of the conveying component 1, combined with the coordinated work of the dust blowing and dust collection systems, realizes continuous and efficient dust removal of the filter, improving production efficiency.
[0022] Specifically, the dust blocking assembly 2 includes a side plate 21 and a mounting plate 22. The side plate 21 is bolted to both sides of the frame body 11, and the mounting plate 22 is fixedly installed at the upper two ends of the side plate 21. A curtain brush 221 is bolted to the bottom of the mounting plate 22.
[0023] In this embodiment, the side plates 21 of the dust-blocking assembly 2 are fixed to both sides of the frame body 11 by bolts, forming a closed dust removal space. This effectively prevents dust particles from overflowing during the dust blowing process and ensures that the blown-off dust can be completely collected by the dust collection assembly 6. The baffle brush 221 at the bottom of the mounting plate 22 typically uses a flexible brush to make slight contact with the filter surface. When the filter passes through, the baffle brush 221 can automatically adapt to the shape and height of the filter, forming a dynamic seal. This ensures the smooth passage of the filter and prevents dust from leaking from the gap between the conveyor belt 12 and the side plates 21. When the upper dust blowing assembly 4 blows dust, the baffle brush 221 can block the high-pressure airflow from blowing dust to the outside of the device, ensuring that the dust is confined within the dust removal space and is easy to collect by the dust collection assembly 6. The side dust blowing assembly 5 blows dust from both sides of the filter, and the side plate 21 acts as a physical barrier to prevent dust from flying out from the side, further improving the dust removal efficiency. The dust blocking assembly 2 effectively reduces the overflow of dust particles through the double seal of the side plate 21 and the baffle brush 221, improving the dust removal efficiency. The dust collection assembly 6 can collect dust more efficiently and reduce the spread of dust in the production environment.
[0024] Specifically, the upper dust blowing assembly 4 includes a fixed base 41, a centrifugal fan 42, a blowing pipe 43, and a blowing hood 44. The fixed base 41 is bolted to the top of the support base 31. The centrifugal fan 42 is fixedly installed on the upper part of the fixed base 41. One end of the blowing pipe 43 is inserted into the air outlet of the centrifugal fan 42, and the other end of the blowing pipe 43 is inserted into the middle of the blowing hood 44. The blowing hood 44 is installed on the upper part of the support base 31 and is located between the two sets of rolling assemblies 34.
[0025] In this embodiment, when the filter moves to the working area of the upper dust blowing assembly 4 via the conveyor belt 12, the centrifugal fan 42 starts, generating a high-pressure airflow. The high-pressure airflow generated by the centrifugal fan 42 is transmitted to the blower hood 44 through the blower pipe 43. One end of the blower pipe 43 is inserted into the blower port of the centrifugal fan 42, and the other end is inserted into the middle of the blower hood 44 to ensure stable airflow transmission. The blower hood 44 is installed on the upper part of the support base 31 and is located between the two sets of rolling assemblies 34, so that the blower hood 44 can be directly aimed at the upper surface of the filter. The high-pressure airflow is evenly blown onto the filter through the blower hood 44, effectively blowing off the dust particles on the upper surface of the filter. The upper dust blowing assembly 4 is fixed by the base 4. The bolt is installed on the top of the support base 31. The structure is compact, occupies little space, and is easy to install, maintain and replace. The centrifugal fan 42 provides a stable high-pressure airflow to ensure dust blowing effect. The design of the air blowing pipe 43 and the air blowing hood 44 allows the airflow to be blown evenly and accurately onto the filter surface, improving dust blowing efficiency. The air blowing hood 44 is located between the two sets of rolling components 34, which can adapt to filter products of different shapes and sizes. The cover and cover installation method of the air blowing hood 44 also makes it easy to adjust or replace as needed. The upper dust blowing component 4 thoroughly removes dust particles from the upper surface of the filter through high-pressure airflow, improving the surface quality of the filter and providing a good foundation for the subsequent powder coating process.
[0026] Specifically, the side dust blowing assembly 5 includes a mounting base 51 and a high-pressure blowing head 52. The horizontal end bolts of the mounting base 51 are installed on both sides of the outer wall of the frame body 11. The high-pressure blowing head 52 is fixedly installed on the vertical end of the mounting base 51. The air outlets of the two sets of high-pressure blowing heads 52 are located on both sides of the roller 345.
[0027] In this embodiment, when the filter moves on the conveyor belt 12 and enters the working area of the side dust blowing assembly 5, the filter is located between the two sets of rollers 345 and close to the air outlet of the high-pressure blowing head 52. The high-pressure blowing head 52 is fixed to both sides of the outer wall of the frame body 11 by the mounting base 51. When the filter is in place, the high-pressure blowing head 52 is activated and sprays high-pressure airflow to the side of the filter. The high-pressure airflow effectively blows off the dust particles on the side of the filter. These dust particles then fall under the action of gravity or are restricted and collected by the dust blocking assembly 2 and the dust collection assembly 6. The side dust blowing assembly 5 is installed on both sides of the outer wall of the frame body 11 by the horizontal bolts of the mounting base 51. The structure is simple and the installation is stable, and it can bear the load. Due to the reaction force generated when the high-pressure air blowing head 52 is working, the high-pressure air blowing head 52 is fixedly installed at the vertical end of the mounting base 51, and the air outlets of the two sets of high-pressure air blowing heads 52 are located on both sides of the roller 345. This design allows the high-pressure airflow to be accurately blown to the side of the filter, improving the dust blowing efficiency. The design of the mounting base 51 allows the position of the high-pressure air blowing head 52 to be adjusted as needed to adapt to filter products of different shapes and sizes. The blowing pressure and angle of the high-pressure air blowing head 52 can also be adjusted according to the actual production situation. The side dust blowing assembly 5 works in conjunction with the upper dust blowing assembly 4 to thoroughly blow dust from the upper surface and sides of the filter, ensuring that the dust particles on the surface of the filter are completely removed.
[0028] Specifically, the dust collection assembly 6 includes a sealed dust collection box 61, a blower 62, and a dust storage box 63. The sealed dust collection box 61 and the dust storage box 63 are both fixedly installed at the bottom of the conveyor belt 12. The blower 62 is fixedly installed at the bottom of the frame body 11. The air inlet of the blower 62 is provided with a dust inlet pipe 621, which is connected to the top of the sealed dust collection box 61. The air outlet of the blower 62 is provided with a dust outlet pipe 622, and the dust outlet of the dust outlet pipe 622 is connected to the dust storage box 63.
[0029] In this embodiment, under the combined action of the upper dust blowing assembly 4 and the side dust blowing assembly 5, dust particles on the surface of the filter are blown off. Under the action of gravity, these dust particles first fall into the sealed dust collection box 61 below the conveyor belt 12. The blower 62 starts, generating negative pressure suction. The air inlet of the blower 62 is connected to the top of the sealed dust collection box 61 through the dust inlet pipe 621. Therefore, the dust particles in the sealed dust collection box 61 are sucked into the dust inlet pipe 621 under the action of negative pressure. The dust particles sucked into the dust inlet pipe 621 are then transported by the blower 62 to the dust outlet pipe 622. The dust outlet of the dust outlet pipe 622 is connected to the dust storage. The dust collection box 63 is a continuous connection, so the dust particles are eventually discharged into the dust collection box 63. The dust collection box 63 collects and stores the dust particles. When the dust in the dust collection box 63 accumulates to a certain level, it can be uniformly processed or removed. The blower 62 provides a strong negative pressure suction, which can quickly suck in the dust particles in the sealed dust collection box 61 and transfer them to the dust collection box 63. This efficient dust collection and rapid transfer design improves the dust collection efficiency. The dust collection component 6 effectively collects the blown-off dust particles, preventing the spread and pollution of dust in the production environment. This improves the working environment and protects the health of the operators.
