[0024] The dust collection device provided in this embodiment aims to improve the problem of secondary pollution caused by powder accumulation and agglomeration.
[0025] The dust collection device provided in this embodiment of the utility model includes a collection chamber 8, a blower 2, a conveying pipe 3, and a cleaning assembly; the input end of the blower 2 is detachably connected to the conveying pipe 3, and the output end of the blower 2 is fixedly connected to the collection chamber 8; the cleaning assembly includes a drive component 10 and a cleaning brush 15, the cleaning brush 15 is located inside the collection chamber 8 and is in contact with the inner wall of the collection chamber 8; the drive component 10 is installed on the top of the collection chamber 8, and the drive component 10 is connected to the cleaning brush 15 in a transmission connection to drive the cleaning brush 15 to move.
[0026] Specifically, the input end of the blower 2 is slidably connected to the conveying pipe 3, and the end of the conveying pipe 3 is sleeved on the outer periphery of the input end of the blower 2. The blower 2 is installed on the support surface of the support frame 1. The support frame 1 supports and fixes the blower 2, and can raise the blower 2 so that the blower 2 is opposite to the side wall of the collection chamber 8. The output end of the blower 2 can be fixedly connected to the side wall of the collection chamber 8. In addition, the support frame 1 can avoid the problem of uneven ground preventing the blower 2 from being placed properly, thus achieving stable installation of the blower 2. The drive component 10 is installed on the top of the collection chamber 8, so that the drive component 10 is located outside the collection chamber 8, preventing dust from entering the drive component 10, extending the service life of the drive component 10, and facilitating maintenance. The cleaning brush 15 abuts against the inner wall of the collection chamber 8, which can effectively clean the sticky dust adsorbed on the chamber wall. The material of the collection chamber 8 is carbon steel or stainless steel to ensure sufficient strength and corrosion resistance, while also ensuring airtightness to prevent dust leakage.
[0027] See Figure 1 The input end of blower 2 is connected to conveying pipe 3, and the output end is connected to collection chamber 8. Blower 2 can suck dust from the work area through conveying pipe 3, thereby drawing the dust into collection chamber 8 for collection. Blower 2 and conveying pipe 3 are detachably connected, allowing conveying pipe 3 to be removed from the input end of blower 2 for easy installation and replacement. See also Figure 2 The drive unit 10 is installed in the collection chamber 8, which supports and fixes the drive unit 10. The drive unit 10 is connected to the cleaning brush 15 located inside the collection chamber 8, allowing the cleaning brush 15 to move along the inner wall of the collection chamber 8. This enables the cleaning brush 15 to clean the dust accumulated on the inner wall of the collection chamber 8 without the need for manual disassembly of the collection chamber 8 for manual cleaning, making it convenient to use. It also avoids the problem of reduced collection efficiency due to dust accumulation, and also avoids the problem of dust agglomeration clogging the funnel 12. Regular cleaning can prevent safety issues such as explosions caused by dust accumulation and secondary pollution caused by airflow. The dust collection device is detachably connected to the conveying pipe 3 through the input end of the blower 2, allowing the conveying pipe 3 to be easily installed and replaced, facilitating operation by staff. The dust collection device drives the cleaning brush 15 to move against the inner wall of the collection chamber 8 by opening the drive component 10, thereby preventing dust from adhering to the inner wall of the collection chamber 8 and achieving the cleaning of dust on the inner wall of the collection chamber 8.
[0028] The structure and shape of the dust collection device are described in detail below: In the optional solution provided by this utility model embodiment, the cleaning brush 15 is in the shape of a ring, and the driving component 10 drives the cleaning brush 15 to move in the vertical direction.
[0029] Specifically, the collection chamber 8 is cylindrical; correspondingly, the cleaning brush 15 is annular, and the cleaning brush 15 fits against the inner peripheral wall of the collection chamber 8. Alternatively, please see... Figure 2 The collection chamber 8 is rectangular; correspondingly, the cleaning brush 15 is square-ring shaped, and multiple inner sidewalls of the collection chamber 8 are fitted with cleaning brushes 15. The driving component 10 is a motor; of course, the driving component 10 can also be other devices that can output power, such as cylinders, and should also be within the protection scope of this utility model embodiment.
[0030] The drive unit 10 drives the ring-shaped cleaning brush 15 to move vertically, so that the cleaning brush 15 can clean the inner wall of the collection chamber 8, and when the cleaning brush 15 moves downward, it can push the dust downward, thus speeding up the cleaning efficiency.
[0031] In the optional solutions provided by the embodiments of this utility model, see Figure 2 The cleaning assembly includes a drive rod 9 and a drive sleeve 11. The drive rod 9 is located inside the collection chamber 8, is arranged vertically, and is connected to the drive component 10. The drive sleeve 11 is sleeved on the drive rod 9 and is threadedly connected to the drive rod 9. The cleaning brush 15 is fixed to the drive sleeve 11.
[0032] Specifically, the transmission rod 9 has an external thread, and the transmission sleeve 11 has an internal thread. The transmission sleeve 11 is fitted onto the transmission rod 9 and is threadedly connected to the transmission rod 9. When the driving member 10 drives the transmission rod 9 to rotate, the transmission rod 9 drives the transmission sleeve 11 to move up and down in the vertical direction. The transmission sleeve 11 drives the cleaning brush 15 to move up and down horizontally.
[0033] A transmission rod 9 is fixedly connected to the output end of the drive component 10. The drive component 10 drives the transmission rod 9 to rotate. A transmission sleeve 11 is threadedly connected to the outside of the transmission rod 9. The transmission rod 9 causes the transmission sleeve 11 to move axially. A cleaning brush 15 is fixedly connected to the outside of the transmission sleeve 11. The transmission sleeve 11 then drives the cleaning brush 15 to clean up and down against the inner wall of the collection chamber 8, preventing dust from adhering to the chamber wall. By utilizing the threaded connection between the transmission rod 9 and the transmission sleeve 11, the rotation drive of the drive component 10 is changed to the up and down translation of the transmission sleeve 11, thereby realizing the up and down translation of the cleaning brush 15. The structure is simple and easy to install, replace, and maintain.
[0034] In the optional embodiment of this utility model, the transmission rod 9 extends out of the collection chamber 8 and connects with the driving component 10, and a bearing is installed between the transmission rod 9 and the collection chamber 8.
[0035] Specifically, the transmission rod 9 runs through the top of the collection chamber 8 and is connected to the chamber body via a bearing.
[0036] The transmission rod 9 extends into the collection chamber 8 and connects to the drive component 10. A bearing is provided between the transmission rod 9 and the collection chamber 8 to ensure that the rotation of the transmission rod 9 does not affect the sealing of the collection chamber 8 and to ensure that dust does not enter the drive component 10.
[0037] In the optional embodiment of this utility model, the cleaning assembly further includes a connecting rod, the two ends of which are connected to the transmission sleeve 11 and the cleaning brush 15, respectively.
[0038] Specifically, multiple connecting rods are provided, and the multiple connecting rods are spaced apart along the extension direction of the cleaning brush 15.
[0039] The connecting rod connects the transmission sleeve 11 and the cleaning brush 15 with high connection strength, preventing the cleaning brush 15 from detaching from the transmission sleeve 11.
[0040] In another embodiment, the collection chamber 8 is cylindrical, the axis of the cleaning brush 15 is set in the vertical direction, and the driving member 10 drives the cleaning brush 15 to rotate around the axis of the collection chamber 8.
[0041] Specifically, the cleaning brush 15 is cylindrical, with its axis set vertically; the outer wall of the cleaning brush 15 abuts against the inner wall of the collection chamber 8. It is worth noting that when the cleaning brush 15 is set vertically and rotates to clean, the collection chamber 8 is cylindrical, ensuring that the cleaning brush 15 is always in contact with the inner wall of the collection chamber 8, thus preventing any dead corners in the collection chamber 8 from being missed during cleaning.
[0042] When the drive unit 10 drives the cleaning brush 15 to rotate, it cleans the inner wall of the collection chamber 8.
[0043] In the optional solutions provided by the embodiments of this utility model, see Figure 1 , Figure 3 and Figure 4 The dust collection device also includes a mounting shell 4 and an elastic limiting assembly. The mounting shell 4 is installed on the outer wall of the conveying pipe 3. The elastic limiting assembly includes a limiting plate 7, a pin 5, and an elastic element 6. The limiting plate 7 is located inside the mounting shell 4. One end of the pin 5 is provided with a limiting protrusion, and the other end passes through the mounting shell 4 and is connected to the limiting plate 7. It also passes through the conveying pipe 3 and extends into the input end of the blower 2. The pin 5 and the mounting shell 4 are slidably engaged. The elastic element 6 is sleeved on the pin 5, and one end is connected to the limiting plate 7, while the other end is connected to the inner wall of the mounting shell 4.
[0044] Specifically, the pin 5 passes through the interior of the mounting housing 4, allowing for stable installation of the pin 5 via the mounting housing 4. An elastic element 6 is located between the limiting plate 7 and the inner wall of the mounting housing 4 opposite to the limiting plate 7. When an external force is applied to the limiting plate 7 to move it outward, the elastic element 6 is compressed; when the external force on the limiting plate 7 is released, the elastic element 6 returns to its original shape, pushing the limiting plate 7 back to its original position. The limiting plate 7 is connected to the pin 5, and one end of the pin 5 with a limiting protrusion is located outside the mounting housing 4, allowing the operator to manipulate the pin 5 to apply external force to the limiting plate 7. Preferably, the elastic element 6 is a spring, sleeved on the outside of the pin 5. When the pin 5 is pulled, the spring is compressed; when the pin 5 is released, the spring returns to its original shape, thus ensuring stable operation of the pin 5.
[0045] When installing the delivery pipe 3, the pin 5 can be inserted into the input end of the delivery pipe 3 and the blower 2; the elastic element 6 of the mounting housing 4 can restrict the movement of the limiting plate 7, thereby preventing the pin 5 from moving and fixing the delivery pipe 3. When replacing the delivery pipe 3, the pin 5 can be pulled out, and the delivery pipe 3 can be easily removed from the input end of the blower 2.
[0046] In the optional solution provided by this utility model embodiment, two mounting shells 4 and two elastic limiting components are provided. The two mounting shells 4 are arranged opposite to each other, and the two elastic limiting components are respectively connected to the two mounting shells 4.
[0047] Specifically, the mounting shell 4 and the elastic limiting component are installed in a one-to-one correspondence. In this embodiment, there are two of each of the mounting shell 4 and the elastic limiting component; of course, other numbers of mounting shell 4 and elastic limiting components, such as three, four or five, should also be within the protection scope of this utility model embodiment.
[0048] There are two mounting shells 4 and two elastic limit components, which improves the connection stability between the conveying pipe 3 and the input end of the blower 2.
[0049] In the optional embodiment of this utility model, the dust collection device further includes a funnel 12 and a trolley 13. The funnel 12 is installed at the bottom of the collection chamber 8, and the trolley 13 is installed below the funnel 12.
[0050] Specifically, a funnel 12 is fixedly connected to the bottom of the collection layer. The settled dust falls through the funnel 12 into the dust collection box of the trailer below, realizing the centralized collection and cleaning of dust.
[0051] A trolley 13 is located directly below the funnel 12. The trolley 13 is movable to facilitate the transfer of a fully loaded dust collection box to the processing area. At the same time, the empty trolley 13 can be quickly replaced, reducing the downtime of the device and improving the continuous operation capability.
[0052] In the optional solution provided by this utility model embodiment, four pillars 14 are fixedly connected to the bottom of the collection chamber 8, and the pillars 14 support the entire device to make the device stable.
[0053] The working principle of this dust collection device is explained in detail below: When the blower 2 draws dust into the collection chamber 8, the drive unit 10 is activated to rotate the transmission rod 9, causing the transmission sleeve 11 to move axially. This drives the cleaning brush 15 to clean the inner wall of the collection chamber 8 up and down, preventing powder from adhering to the chamber wall and thus cleaning the dust on the inner wall of the collection chamber 8.
[0054] When installing the conveying pipe 3, the pin 5 can be inserted into the input end of the conveying pipe 3 and the blower 2. Due to the action of the elastic element 6 inside the mounting housing 4, the limiting plate 7 is prevented from moving, which in turn prevents the pin 5 from moving, thus fixing the conveying pipe 3. When disassembling the conveying pipe 3, the pin 5 can be pulled out, and the conveying pipe 3 can be easily removed from the input end of the blower 2; thus, the conveying pipe 3 can be easily installed and replaced, bringing convenience to the operator.
[0055] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
