Description

Technical Field

[0001] This application relates to the field of dust removal technology in production workshops, and more specifically, to a dust removal system. Background Technology

[0002] The production and manufacturing of certain products generate large amounts of dust and other impurities. Taking papermaking as an example, processes such as cutting, rewinding, and waste recycling produce significant amounts of paper dust. This dust not only affects air quality in the workshop and harms the health of operators, but can also pose safety hazards such as dust explosions. Therefore, papermaking workshops are typically equipped with dust removal systems to control dust dispersion.

[0003] Currently, mobile dust collection systems are widely used in production workshops such as paper mills. These systems are primarily used to control dust generation at localized points and can be deployed near equipment that generates various types of dust and impurities. In paper production workshops, they are typically placed in dispersed or intermittent dust-generating areas such as paper cutters, rewinders, and waste outlets. Their core advantage lies in their high flexibility: mobile dust collection systems are usually equipped with casters, allowing for rapid movement to different workstations and adapting to multi-workstation, small-batch operation scenarios. Simultaneously, these systems can achieve "on-demand cleaning" dust source capture, effectively reducing the diffusion of dust into the workshop environment and improving local air quality.

[0004] The basic working principle of existing mobile dust collection systems is as follows: a negative pressure fan connects to a suction pipe to extract paper dust from the air; a filter device (such as a filter plate) is installed on the suction pipe to intercept and filter the paper dust, and the filtered air is discharged from the system through the negative pressure fan. However, this technical solution has significant drawbacks in practical applications: after a certain period of operation, paper dust accumulates on the surface of the filter device, leading to increased filtration resistance, decreased suction efficiency, and even clogging, rendering the filter device inoperable. Therefore, operators must stop the machine to clean or replace the filter device, disrupting the continuity of dust collection operations. For multi-station, intermittently dust-generating paper mills, frequent shutdowns for cleaning or replacement significantly reduce the overall operating efficiency of the dust collection system, making continuous dust collection impossible with existing mobile dust collection systems. Summary of the Invention

[0005] In view of this, this application provides a dust removal system to solve the technical problem of low dust removal efficiency in existing mobile dust removal systems.

[0006] This application provides a dust removal system, wherein the dust removal system includes: A mobile platform and a traveling mechanism disposed below the mobile platform; A cleaning chamber and a filter cleaning device are installed on the mobile platform. The system includes a negative pressure fan and a vacuum cleaner rotating body. The negative pressure fan is mounted on the mobile platform, and the vacuum cleaner rotating body is rotatably mounted on the mobile platform. The vacuum cleaner rotating body has at least two filter structures. Each filter structure includes a filter element and an air intake, an exhaust port, and an airflow channel formed on the vacuum cleaner rotating body. The airflow channel is located between the air intake and the exhaust port, and the filter element is located in the airflow channel. The vacuum cleaner rotating body can rotate so that any one of the filter structures is in a working position. The exhaust port of the filter structure in the working position is connected to the air intake of the negative pressure fan. When one of the at least two filter structures is in the working position, the other filter structure is located in the cleaning chamber.

[0007] Furthermore, the vacuuming rotating body is a ring-shaped body.

[0008] Further, the filter structure includes a first through hole, a second through hole, and a third through hole formed on the dust-collecting rotating body. The first through hole, the second through hole, and the third through hole are arranged sequentially along the circumferential direction of the dust-collecting rotating body. The first end of each of the first through hole, the second through hole, and the third through hole extends through one axial side of the dust-collecting rotating body, and the second end of each of the first through hole, the second through hole, and the third through hole extends through the other axial side of the dust-collecting rotating body. A first cavity connecting the first through hole and the second through hole and a second cavity connecting the second through hole and the third through hole are formed inside the dust-collecting rotating body. The first cavity and the... The second cavity is offset along the axial direction of the dust-collecting rotating body. A portion of each of the first through hole, the second through hole, and the third through hole, together with the first cavity and the second cavity, form the airflow channel. The first end of the first through hole forms the air intake port, and the second end of the third through hole forms the exhaust port. The filter includes a first filter disposed in the first through hole, a second filter disposed in the second through hole, and a third filter disposed in the third through hole. The first filter is adjacent to the air intake port, the second filter is located between the first cavity and the second cavity, and the third filter is adjacent to the exhaust port.

[0009] Furthermore, the first filter element is detachably installed in the first through hole, the second filter element is detachably installed in the second through hole, and the third filter element is detachably installed in the third through hole. The first filter element, the second filter element, and the third filter element are all filter plates.

[0010] Furthermore, the dust removal system includes a sealing cover, and the dust suction rotating body is rotatably sealed with the sealing cover. The second end of the first through hole, the first end and the second end of the second through hole, and the first end of the third through hole in the filter structure at the working position are blocked by the sealing cover.

[0011] Furthermore, the sealing cover includes a first baffle that seals and fits the end face of one axial end of the vacuuming rotating body and a second baffle that seals and fits the end face of the other axial end of the vacuuming rotating body. The second end of the first through hole and the second end of the second through hole in the filter structure in the working position are blocked by the second baffle, and the first end of the second through hole and the first end of the third through hole in the filter structure in the working position are blocked by the first baffle.

[0012] Furthermore, the filter cleaning device includes a flushing pipe disposed within the cleaning chamber and a plurality of flushing nozzles disposed on the flushing pipe, the plurality of flushing nozzles being directed toward the second ends of the first through hole, the second through hole and the third through hole located in the filter structure within the cleaning chamber.

[0013] Furthermore, the dust removal system includes a connecting pipe, one end of which is sealed against the other end of the axial direction of the dust suction rotating body, the other end of which is connected to the air inlet of the negative pressure fan, and the exhaust port in the filter structure in the working position is connected to one end of the connecting pipe.

[0014] Furthermore, the working position is located above the cleaning chamber.

[0015] Furthermore, the mobile platform is equipped with a main controller and a hinge frame. The vacuum suction rotating body is rotatably mounted on the hinge frame via a rotating shaft. A motor is mounted on the hinge frame, and the output shaft of the motor is connected to the rotating shaft. The main controller is connected to the motor and the filter cleaning equipment via signals.

[0016] The beneficial effects of the dust removal system provided in this application are as follows: Compared to existing technologies, the dust removal system provided by this invention has a mobile platform and a traveling mechanism located below the mobile platform. This allows the entire dust removal system to be easily moved by the mobile platform to different workstations in paper production workshops or other workshops where dust and other impurities are generated, enabling targeted treatment of localized dust-generating points. Furthermore, because the dust-collecting rotating body can rotate, any filter structure can be in a working position. The exhaust port of the filter structure in the working position is connected to the air inlet of the negative pressure fan. Taking this application with two filter structures as an example, when one filter structure is in the working position, the other filter structure is located inside the cleaning chamber. Therefore, the filter structure in the working position operates through the negative pressure fan, allowing external paper dust or other dust to enter the airflow channel through the suction port. The air passing through the filter element is trapped on the filter element, and then the air after filtering the paper dust enters the negative pressure fan through the exhaust port of the filter structure in the working position and the air inlet of the negative pressure fan in sequence, and finally exits from the air outlet of the negative pressure fan. During this process, the filter element of another filter structure located in the cleaning chamber can be cleaned by the filter element cleaning equipment. After the filter structure in the working position has been working for a period of time, the dust collection rotor can be rotated, so that the filter structure that has been cleaned in the cleaning chamber is in the working position, and the filter structure that was originally in the working position can enter the cleaning chamber with the dust collection rotor to be cleaned by the filter element cleaning equipment. Therefore, the dust removal system provided by this invention can quickly switch the filter structure in the working position to ensure the rapid replacement of the cleaned filter structure, so as to ensure the continuity and efficiency of the entire suction dust removal process.

[0024] See Figures 1 to 9 This application provides a dust removal system that can be applied in production workshops with large amounts of dust, grime, or paper dust. The dust removal system includes: The mobile platform 1 and the traveling mechanism located below the mobile platform 1. The traveling mechanism may include multiple casters 2, which facilitates the manual pushing of the mobile platform 1 to different workstations in the paper production workshop or other workshops where dust and other impurities are generated. The traveling mechanism may also be an electrically driven traveling wheel mechanism. A cleaning chamber 3 is mounted on the mobile platform 1, and a filter cleaning device is mounted in the cleaning chamber 3. The negative pressure fan 4 and the dust collection rotating body 100 are provided. The negative pressure fan 4 is mounted on the mobile platform 1, and the dust collection rotating body 100 is rotatably mounted on the mobile platform 1. The dust collection rotating body 100 is provided with at least two (e.g., two) filter structures. The filter structure includes a filter element and an air intake 101, an exhaust 102 and an airflow channel formed on the dust collection rotating body 100. The airflow channel is located between the air intake 101 and the exhaust 102, and the filter element is located in the airflow channel. The dust collection rotating body 100 can rotate so that any filter structure is in a working position. The exhaust 102 of the filter structure in the working position is connected to the air intake of the negative pressure fan 4. When one of the at least two filter structures is in the working position, the other filter structure is located in the cleaning chamber 3.

[0025] Because the dust removal system provided by this invention has a mobile platform 1 and a traveling mechanism located below the mobile platform 1, it is convenient to move the entire dust removal system to different workstations in the paper production workshop or other workshops where dust and other impurities are generated, for targeted treatment of local dust-generating points. In addition, because the dust suction rotating body 100 can rotate, any filter structure can be in the working position. The exhaust port 102 of the filter structure in the working position is connected to the air inlet of the negative pressure fan 4. Taking the two filter structures in this application as an example, when one of the two filter structures is in the working position, the other filter structure is located in the cleaning chamber 3. Therefore, the filter structure in the working position is operated by the negative pressure fan 4, so that external paper dust or other dust enters the airflow channel through the suction port 101 and is intercepted by the filter element. The air, after being filtered of paper dust, passes through the exhaust port 102 of the filter structure in the working position and the air inlet of the negative pressure fan 4, and finally exits from the air outlet of the negative pressure fan 4. During this process, the filter element of another filter structure located in the cleaning chamber 3 can be cleaned by the filter element cleaning equipment. After the filter structure in the working position has been working for a period of time, the dust collection rotating body 100 can be rotated, so that the filter structure that has been cleaned in the cleaning chamber 3 is in the working position. The filter structure that was originally in the working position can enter the cleaning chamber 3 with the dust collection rotating body 100 to be cleaned by the filter element cleaning equipment. Therefore, the dust removal system provided by the present invention can quickly switch the filter structure in the working position to ensure the rapid replacement of the cleaned filter structure, so as to ensure the continuity and efficiency of the entire suction dust removal process.

[0026] It is understood that when there are three or more filter structures in this application, there are filter structures that are neither in the working position nor in the cleaning chamber 3, but as the vacuuming rotating body 100 rotates, it can be ensured that the next filter structure to reach the working position is the filter structure that has passed through the cleaning chamber 3 before.

[0027] According to one embodiment of this application, the vacuuming rotating body 100 is an annular body, and the axis of the annular body is the rotation axis of the vacuuming rotating body 100.

[0028] According to a specific embodiment of this application, the vacuuming rotating body 100 can be rotated either manually or electrically.

[0029] According to one embodiment of this application, the filter structure includes a first through hole 103, a second through hole 104, and a third through hole 105 formed on a vacuuming rotating body 100. The first through hole 103, the second through hole 104, and the third through hole 105 are arranged sequentially along the circumferential direction of the vacuuming rotating body 100. The first end of each of the first through hole 103, the second through hole 104, and the third through hole 105 extends through one axial side of the vacuuming rotating body 100, and the second end of each of the first through hole 103, the second through hole 104, and the third through hole 105 extends through the other axial side of the vacuuming rotating body 100. A first cavity 106 connecting the first through hole 103 and the second through hole 104 and a second cavity 107 connecting the second through hole 104 and the third through hole 105 are formed inside the vacuuming rotating body 100. The first cavity 106 and the second cavity 107 are offset along the axial direction of the vacuuming rotating body 100. A portion of each of the holes 103, 104, and 105, along with the first and second cavities 106 and 107, together form an airflow channel. The first end of the first through hole 103 forms an intake port 101, and the second end of the third through hole 105 forms an exhaust port 102. The filter element includes a first filter element 5 disposed in the first through hole 103, a second filter element 6 disposed in the second through hole 104, and a third filter element 7 disposed in the third through hole 105. The first filter element 5 is adjacent to the intake port 101, the second filter element 6 is located between the first and second cavities 106 and 107, and the third filter element 7 is adjacent to the exhaust port 102. External paper dust or other dust enters the airflow channel through the intake port 101 and passes through the filtering action of the first filter element 5, the second filter element 6, and the third filter element 7 in sequence, thereby improving the filtration and dust removal effect of the filter structure.

[0030] According to a specific embodiment of this application, the first filter element 5 is detachably installed in the first through hole 103, the second filter element 6 is detachably installed in the second through hole 104, and the third filter element 7 is detachably installed in the third through hole 105. The first filter element 5, the second filter element 6, and the third filter element 7 are all filter plates, which facilitates the disassembly of the first filter element 5, the second filter element 6, and the third filter element 7. The detachable connection method is a known mechanical connection method, such as fixing by clips or screws.

[0031] According to one embodiment of this application, the dust removal system includes a sealing cover 200. The dust suction rotating body 100 is rotatably sealed with the sealing cover 200. The second end of the first through hole 103, the first and second ends of the second through hole 104, and the first end of the third through hole 105 in the filter structure in the working position are blocked by the sealing cover 200. This ensures that the airflow path formed by the filter structure in the working position can only enter from the first end of the first through hole 103 (inlet 101), and then flow out of the filter structure sequentially through the first filter element 5, the first cavity 106, the second filter element 6, the second cavity 107, the third filter element 7, and the second end of the third through hole 105 (exhaust port 102). In this way, the ports of the second end of the first through hole 103, the ports of both ends of the second through hole 104, and the port of the first end of the third through hole 105 will not interfere with the airflow path formed by the filter structure, ensuring the normal operation of the suction dust removal work.

[0032] According to a specific embodiment of this application, the sealing cover 200 includes a first baffle 201 that seals and fits the end face of one axial end of the vacuuming rotating body 100 and a second baffle 202 that seals and fits the end face of the other axial end of the vacuuming rotating body 100. The second end of the first through hole 103 and the second end of the second through hole 104 in the filter structure in the working position are blocked by the second baffle 202, and the first end of the second through hole 104 and the first end of the third through hole 105 in the filter structure in the working position are blocked by the first baffle 201.

[0033] According to one embodiment of this application, the filter cleaning device includes a flushing pipe 8 disposed in a cleaning chamber 3 and a plurality of flushing nozzles 9 disposed on the flushing pipe 8. The plurality of flushing nozzles 9 are directed toward the second ends of the first through hole 103, the second through hole 104, and the third through hole 105 in the filter structure located in the cleaning chamber 3 (i.e., the plurality of flushing nozzles 9 are located on the other side of the axial direction of the dust suction rotating body 100). Since the airflow path formed by the filter structure in the working position can only enter from the first end of the first through hole 103 (inlet 101), and then flow out of the filter structure sequentially through the first filter element 5, the first cavity 106, the second filter element 6, the second cavity 107, the third filter element 7, and the second end of the third through hole 105 (exhaust port 102), the paper dust intercepted by the first filter element 5, the second filter element 6, and the third filter element 7 mainly accumulates on the side of the first filter element 5 facing the first end of the first through hole 103, the side of the second filter element 6 facing the first end of the second through hole 104, and the side of the third filter element 7 facing the third through hole 105. On one side of the first end of the hole 105, the rinsing nozzle 9 is located on the other side of the axial direction of the vacuuming rotating body 100. It can spray cleaning water from the side of the first filter element 5 facing the second end of the first through hole 103, the side of the second filter element 6 facing the second end of the second through hole 104, and the side of the third filter element 7 facing the second end of the third through hole 105, allowing the water to flow through the first filter element 5 facing the first end of the first through hole 103, the second filter element 6 facing the second end of the second through hole 104, and the third filter element 7 facing the second end of the third through hole 105. This facilitates the rinsing of the first filter element 5 facing the first end of the first through hole 103, the second filter element 6 facing the second end of the second through hole 104, and the third filter element 7 facing the second end of the third through hole 105. The paper dust trapped on the side of the first end of the second through hole 104 and the side of the third filter 7 facing the first end of the third through hole 105 are flushed out of the first ends of the first through hole 103, the second through hole 104 and the third through hole 105 respectively, so that the paper dust is wetted and falls into the cleaning chamber 3. Of course, the paper dust trapped at other positions of the first filter 5, the second filter 6 and the third filter 7 or the paper dust at other positions in the first through hole 103, the second through hole 104 and the third through hole 105 can also be flushed out.

[0034] In addition, there can be multiple flushing pipes 8, and multiple flushing pipes 8 are connected to the outlet of a high-pressure water pump (not shown) located on the mobile platform 1 through a main water pipe 10. A water tank (not shown) connected to the inlet of the high-pressure water pump can also be installed on the mobile platform 1.

[0035] According to one embodiment of this application, the dust removal system includes a connecting pipe 11. One end face of the connecting pipe 11 is sealed to the end face of the other axial end of the dust suction rotating body 100. The other end of the connecting pipe 11 is connected to the air inlet of the negative pressure fan 4. The exhaust port 102 in the filter structure in the working position is connected to one end of the connecting pipe 11. Specifically, the other end of the connecting pipe 11 can be connected to the air inlet of the negative pressure fan 4 through the airflow pipe 12. In addition, the working position is located above the cleaning chamber 3.

[0036] According to a specific embodiment of this application, a main controller and a hinge frame 13 are provided on the mobile platform 1. The vacuuming rotating body 100 is rotatably mounted on the hinge frame 13 via a rotating shaft 14. A motor 15 is provided on the hinge frame 13. The output shaft of the motor 15 is connected to the rotating shaft 14. The main controller is connected to the motor 15 and the filter cleaning equipment respectively. Specifically, the main controller is connected to the high-pressure water pump. The main controller can automatically switch the filter structure in the working position and the cleaning chamber 3, and clean the filter structure periodically.

[0037] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
