[0002] In the packaging industry, such as food packaging and chemical product packaging, a large amount of dust is often generated. This dust not only pollutes the working environment and affects the health of operators, but also may cause material waste and even pose certain safety hazards, such as dust explosions.

[0003] Currently, existing dust collection devices on the market have several shortcomings in use. Some devices have low dust collection efficiency, failing to effectively collect all the dust generated during the packaging process; some devices have inadequate structural design, resulting in high energy consumption and inconvenient maintenance; furthermore, some devices have poor sealing, easily leading to dust leakage, affecting collection efficiency and the working environment. Additionally, existing dust collection devices lack flexibility in airflow adjustment, making it difficult to tailor adjustments based on varying dust generation levels, further impacting collection efficiency and energy consumption. Utility Model Content

[0008] Furthermore, the lower end of the cyclone separator is provided with a first dust discharge port, and a first valve is installed at the first dust discharge port. The first valve is used to control the opening and closing of the first dust discharge port.

[0009] Furthermore, the first connection port is connected to the upper air outlet of the cyclone separator through a sealing connection component, which is a rubber sealing ring.

[0010] Furthermore, the impeller is a centrifugal impeller, and the blades of the centrifugal impeller have a backward-curved structure.

[0011] Furthermore, a flexible connecting pipe is provided between the air outlet pipe and the air inlet of the filter device. The flexible connecting pipe is a silicone tube, which is used to buffer the airflow impact and compensate for the installation error of the device.

[0012] Furthermore, the speed controller is a frequency converter, which adjusts the motor speed by changing the frequency of the motor input power supply.

[0013] Furthermore, the speed controller is connected to the speed regulator.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] See Figures 1-3 This embodiment discloses an automatic dust collection device for packaging, including a cyclone separator 101 and a filter device 102.

[0033] An air extraction device 103 is provided at the upper air outlet of the cyclone separator 101, and the air outlet of the air extraction device 103 is connected to the air inlet of the filter device 102.

[0034] The exhaust device 103 includes a housing 104, a motor 105, and an impeller 106. The housing 104 has a cylindrical structure, and a first connection port 107 is provided on the lower end face of the housing 104. The first connection port 107 is connected to the upper air outlet of the cyclone separator 101. The motor 105 is installed on the upper end of the housing 104. The impeller 106 is located inside the housing 104 and is connected to the motor 105. An air outlet pipe 108 is provided on the side of the housing 104. The air outlet pipe 108 is tangent to the housing 104 and is connected to the air inlet of the filter device 102. The motor 105 is connected to a speed regulator, which is used to adjust the speed of the motor 105.

[0035] This invention incorporates a cyclone separator 101 and a filter device 102. Dust-laden gas generated during the packaging process first enters the cyclone separator 101, where it undergoes initial separation. Larger dust particles are separated by centrifugal force. The gas then enters the filter device 102 for further filtration, effectively improving dust collection efficiency and reducing dust pollution in the working environment. Simultaneously, the exhaust device 103 provides power for the flow of dust-laden gas, ensuring smooth dust collection. The exhaust device 103 has a cylindrical outer shell 104, with the outlet pipe 108 tangential to it, allowing airflow within the shell 104, reducing airflow resistance and improving extraction efficiency. A motor 105 is connected to a speed controller, allowing adjustment of the motor speed based on the amount of dust generated, thereby regulating the extraction volume of the exhaust device 103. This ensures effective collection while reducing energy consumption and improving the device's flexibility and applicability.

[0036] Furthermore, in some preferred embodiments, a first dust discharge port 109 is provided at the lower end of the cyclone separator 101, and a first valve is installed at the first dust discharge port 109. The first valve is used to control the opening and closing of the first dust discharge port 109. When the dust collected in the cyclone separator 101 reaches a certain amount, the first valve is opened to discharge the dust. This is convenient to operate and facilitates centralized dust treatment, while preventing excessive dust accumulation in the cyclone separator 101 from affecting the separation effect.

[0037] Furthermore, in some preferred embodiments, the first connection port 107 is connected to the upper air outlet of the cyclone separator 101 via a sealing connection component, which is a rubber sealing ring. The rubber sealing ring effectively enhances the sealing between the two, preventing dust-laden gas from leaking at the connection point, ensuring effective dust collection, and avoiding dust pollution of the working environment.

[0038] Furthermore, in some preferred embodiments, the impeller 106 is a centrifugal impeller 106, and the blades of the centrifugal impeller 106 have a backward-curved structure. When the centrifugal impeller 106 with backward-curved blades is in operation, the airflow is relatively smooth, the noise generated is low, and its efficiency is high, enabling it to provide a larger air volume at the same power, which is beneficial for improving dust collection efficiency and reducing energy consumption.

[0039] Furthermore, in some preferred embodiments, a flexible connecting pipe 110 is provided between the air outlet duct 108 and the air inlet end of the filter device 102. The flexible connecting pipe 110 is a silicone tube. Silicone tubes have good flexibility and elasticity, which can buffer airflow impact, reduce damage to the filter device 102 from airflow, and extend the service life of the device. At the same time, the flexible connecting pipe 110 can also compensate for errors generated during device installation, facilitating the installation and debugging of the device.

[0040] Furthermore, in some preferred embodiments, the speed controller is a variable frequency drive (VFD), which adjusts the speed of motor 105 by changing the frequency of the power supply input to motor 105. This allows for flexible adjustment based on different dust generation conditions, ensuring effective collection while minimizing energy consumption.

[0041] Furthermore, the speed controller is connected to a controller. The controller enables automatic control of the speed controller. Operators can send control signals to the speed controller based on preset dust generation values ​​or real-time monitoring data, thereby automatically adjusting the motor speed (105 rpm). This improves the automation level of the device, reduces manual operation, and increases work efficiency.

[0042] Furthermore, the housings 104 of both the cyclone separator 101 and the filter device 102 are made of manganese steel.

[0043] The output shaft of the motor 105 is connected to the impeller 106 via a coupling.

[0044] Furthermore, in some preferred embodiments, the filtration device 102 includes a first outer shell 111, a top cover 112, a partition 113, and a filter cylinder 114. The partition 113 is disposed on the upper end of the first outer shell 111, and the filter cylinder 114 is detachably disposed on the partition 113. The top cover 112 is detachably connected to the first outer shell 111. The first outer shell 111 is provided with a first air inlet, which is connected to an air outlet 108. An exhaust pipe 115 is provided on the outer shell 104, and a slag discharge port 116 is provided at the lower end of the first outer shell 111. When the filtration effect of the filter cylinder 114 decreases after a period of use, the top cover 112 can be opened to remove the filter cylinder 114 for cleaning or replacement. The operation is convenient and maintenance is easy. The first outer casing 111 is provided with a first air inlet connected to the air outlet pipe 108. The exhaust pipe 115 is used to discharge the filtered clean air. The slag discharge port 116 at the lower end of the first outer casing 111 is used to discharge the dust filtered by the filter cartridge 114, ensuring the normal operation of the filter device 102 and the effective collection of dust.

[0045] Furthermore, a valve is installed at the slag discharge port 116.

[0046] Furthermore, in some preferred embodiments, the first dust discharge port 109 is connected to a coarse particle recovery box, and the slag discharge port 116 of the filter device 102 is connected to a fine particle recovery box.

[0047] Furthermore, in some preferred embodiments, a spiral guide rib is coaxially provided below the impeller 106, and the gap between the spiral guide rib and the inner wall of the outer shell 104 is 2-5mm;

[0048] The spiral guide rib has a spiral angle of 15°-25° and a height of 1 / 5-1 / 3 of the impeller diameter.

[0049] Furthermore, the gap between the spiral guide rib and the inner wall of the outer casing 104 is 4mm; the spiral angle of the spiral guide rib is 20°, and its height is 1 / 3 of the diameter of the impeller 106. The spiral guide rib, coaxially arranged below the impeller, can guide the airflow to form a regular spiral motion, which cooperates with the cylindrical structure of the outer casing 104 and the tangentially arranged air outlet pipe to enhance the swirling intensity of the airflow in the extraction device.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
