Technical Field

[0001] The invention relates to the field of purification devices, in particular to a smoke circulation purification device. Background Art

[0002] In the industrial production process, smoke pollution is a common problem. The existing conventional purification devices use a single-stage filter element to separate dust from air. When dealing with smoke from external equipment such as 3D printers, the filtration accuracy and filtration area are insufficient, resulting in frequent replacement of the filter element and high pressure on equipment maintenance. In addition, the purification device cannot meet the requirements of full sealing and pressure maintenance, resulting in a large loss of inert gas and other problems. Summary of the invention

[0003] Based on this, it is necessary to provide a smoke circulation purification device to address the problems that the existing purification device uses single-stage filtration, which results in insufficient filtration accuracy and filtration area, leading to frequent filter element replacement and high pressure on equipment maintenance.

[0005] The present application discloses a smoke circulation purification device, which is connected to an external device such as a 3D printer through an air inlet and an air outlet, so that the dust generated by the 3D printer can directly enter the filter device for filtering and purification, and the purification efficiency is higher. The installation between the first filter component, the second filter component and the third filter component of the device does not require bolts and other connectors, so the sealing performance of the whole machine is better. This design makes it possible to use inert gases such as nitrogen to better evacuate the oxygen inside the device, and the safety performance of the device is high. In addition, the good sealing reduces the loss of nitrogen, which is conducive to saving resources. A multi-stage filtration system is formed by the arrangement of the first filter component, the second filter component and the third filter component. This design can remove dust particles of different particle sizes in the air step by step, thereby improving the overall filtration accuracy and purification effect, with higher filtration accuracy and low filtration pressure of the filter element, so there is no need to frequently replace the filter element, and the equipment maintenance pressure is low.

[0006] In one embodiment, the second filter assembly includes a filter housing, an air storage housing and a filter element. The filter housing is arranged on the body assembly and is located in the accommodating chamber. The filter housing is provided with the second filter chamber. The air storage housing is arranged on the filter housing. The air storage housing is provided with an air storage chamber connected to an external air source. The air storage chamber can be connected to the second filter chamber. The filter element is arranged on the filter housing and is located in the second filter chamber.

The setting of the air storage chamber allows the high-pressure airflow entering from the outside to be temporarily stored, ensuring that there is enough air source to blow off the dust on the filter element. The air storage chamber can be connected to the second filter chamber, so that the airflow in the air storage chamber can be transported to the second filter chamber to blow off the dust attached to the second filter chamber.

[0007] In one of the embodiments, it also includes a dust removal assembly, a drive assembly and a cover assembly, the dust removal assembly is arranged on the air storage shell and extends to the interior of the filter element, the filter element is arranged around the dust removal assembly, the dust removal assembly can rotate relative to the filter device, the dust removal assembly is provided with a first air inlet and an air outlet, the first air inlet can be communicated with an external air source, the air outlet is arranged toward the filter element, the dust removal assembly is provided with a first air transmission channel, the first air inlet, the first air transmission channel and the air outlet are communicated in sequence, the drive assembly is arranged on the air storage shell, the drive assembly is transmission-connected with the dust removal assembly, the drive assembly can drive the dust removal assembly to rotate relative to the filter device, the cover assembly is arranged on the drive assembly, the drive assembly can drive the cover assembly to rotate relative to the filter device, the cover assembly can rotate at least a first angle and a second angle relative to the filter device, when the cover assembly rotates the first angle, the cover assembly closes the first air inlet, and when the cover assembly rotates the second angle, the first air inlet is communicated with the external air source. The high-pressure airflow passes through the first air inlet, the first air delivery channel and the air outlet in sequence and is output toward the filter device, so that the dust particles attached to the filter device are efficiently blown off, and the efficiency of dust cleaning is improved. The dust removal component can rotate relative to the filter device under the action of the driving component, and multi-angle dust blowing can be achieved. This design ensures that dust particles located in all directions on the filter device can be blown off, further enhancing the cleaning effect and reducing the possibility of dust residue. The first air inlet can be closed or opened by the cover plate component, thereby realizing intermittent air supply to the dust removal component, so that the dust removal component sprays intermittent airflow to the filter device, which is conducive to further improving the dust removal effect. This intermittent working mode also realizes the effective use of energy. Since the dust particles can be cleaned off from the filter device in a timely and effective manner, the dust accumulated in the filter device is significantly improved, the air permeability and filtering efficiency of the filter device are improved, and the filter device can continuously and stably play a good purification role. The dust removal component can automatically rotate relative to the filter device through the setting of the driving component, with a high degree of automation, reducing the labor intensity of the operator. The dust removal component has its air outlet facing the filter element, which enhances the dust blowing effect and helps keep the filter element clean and running efficiently. The filter element surrounds the dust removal component, so that the high-pressure airflow entering the dust removal component output can fully contact the filter element, further improving the dust removal efficiency.

An efficient and reliable power transmission system is formed by the arrangement of the driving motor, the driving gear and the driven gear, thereby driving the rotation of the dust removal assembly and the cover assembly.

When the cover assembly rotates to a first angle, the second air inlet is closed and the dust removal assembly stops blowing air; when the cover assembly rotates to a second angle, the second air inlet is connected and the dust removal assembly starts blowing air. This optimized airflow control mechanism realizes intermittent air blowing and dust removal, improves dust removal efficiency and reduces energy consumption.

The air pressure of the gas storage chamber can be detected by setting the pressure sensor. When the air pressure in the gas storage chamber is sufficient, the controller drives the dust removal assembly to rotate at a higher second speed to achieve rapid intermittent high-pressure airflow delivery, thereby ensuring efficient dust removal of the second filter assembly by the dust removal assembly. When the air pressure in the air storage chamber is insufficient, the controller drives the dust removal assembly to rotate at a lower first speed, so that the first air inlet is connected to the air storage chamber for a longer period of time, ensuring sufficient air supply to the dust removal assembly, thereby ensuring the dust removal effect.

The installation between the first filter component 21, the second filter component 22 and the third filter component 23 of the device does not require bolts and other connectors, so the sealing performance of the whole machine is better. This design makes it possible to use inert gases such as nitrogen to better evacuate the oxygen inside the device, and the safety performance of the device is high. Moreover, the good sealing reduces the loss of nitrogen, which is conducive to saving resources. A multi-stage filtration system is formed by the arrangement of the first filter component 21, the second filter component 22 and the third filter component 23.
