TECHNICAL FIELD

[0001] The present application relates to the field of purification devices, in particular to a smoke dust circulating purification device. BACKGROUND

[0002] In the industrial production process, smoke dust pollution is a common problem. The existing conventional purification device adopts single-stage filtration of filter core to separate dust and air. When treating smoke dust of external equipment such as 3D printer, the filtration precision and filtration area are not enough, resulting in frequent replacement of filter core and high pressure of equipment maintenance. Moreover, the internal purification device cannot be fully sealed and pressure maintained, resulting in large loss of inert gas and other problems. SUMMARY

[0003] Therefore, it is necessary to provide a smoke dust circulating purification device to solve the problems of insufficient filtration precision and filtration area, frequent replacement of filter core and high pressure of equipment maintenance caused by single-stage filtration of the existing purification device.

[0005] The application discloses a smoke dust circulating purification device, which is communicated with external equipment 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 filtering device for filtration and purification, and the purification efficiency is higher. The installation between the first filtering assembly, the second filtering assembly and the third filtering assembly of the device does not need bolts and other connecting pieces, so that the sealing performance of the whole machine is better. This design makes it possible to better empty the oxygen in the interior of the device by using inert gas such as nitrogen, and the safety performance of the device is high. Moreover, the good sealing performance reduces the loss of nitrogen, which is beneficial to resource saving. The first filtering assembly, the second filtering assembly and the third filtering assembly form a multi-stage filtering system. This design can remove dust particles of different particle sizes in the air step by step, thereby improving the overall filtering precision and purification effect, the filtering precision is higher, the filter core filtering pressure is small, so that the filter core does not need to be frequently replaced, and the equipment maintenance pressure is small.

The setting of the filter piece can separate the dust from the air, and the filtering efficiency is good. The setting of the gas storage cavity can temporarily store the high-pressure gas flow entering from the outside, so that there is enough gas source to blow off the dust on the filter piece. The gas storage cavity can be communicated with the second filtering cavity, so that the gas flow in the gas storage cavity can be conveyed into the second filtering cavity to blow off the dust adhered in the second filtering cavity.

[0007] In one of the embodiments, a dust removal assembly, a driving assembly and a cover plate assembly are further included. The dust removal assembly is arranged on the gas storage shell and extends to the inside of the filter element. The filter element is arranged around the dust removal assembly. The dust removal assembly is capable of rotating relative to the filter device. The dust removal assembly is provided with a first air inlet and an air outlet. The first air inlet is capable of communicating with an external air source. The air outlet is arranged towards the filter element. The dust removal assembly is provided with a first air conveying channel. The first air inlet, the first air conveying channel and the air outlet are sequentially communicated.

The driving assembly is capable of driving the dust removal assembly to rotate relative to the filter device. The cover plate assembly is arranged on the driving assembly. The driving assembly is capable of driving the cover plate assembly to rotate relative to the filter device. The cover plate assembly is capable of rotating at least a first angle and a second angle relative to the filter device. When the cover plate assembly rotates at the first angle, the cover plate assembly closes the first air inlet. When the cover plate assembly rotates at the second angle, the first air inlet is communicated with the external air source. The high-pressure air flow sequentially passes through the first air inlet, the first air conveying channel and the air outlet and is output towards the filter device, so as to efficiently blow off the dust particles attached to the filter device, thereby improving the dust cleaning efficiency. The dust removal assembly is capable of rotating relative to the filter device under the action of the driving assembly, so as to realize multi-angle dust blowing. This design ensures that the dust particles in all directions on the filter device can be blown off, further enhances the cleaning effect and reduces the possibility of dust residue. The cover plate assembly can close or open the first air inlet, so as to realize intermittent air supply to the dust removal assembly, so that the dust removal assembly sprays intermittent air flow to the filter device, which is beneficial to further improve the dust removal effect. This intermittent working mode also realizes effective use of energy. Since the dust particles can be effectively cleaned from the filter device in time, the dust accumulated on the filter device is significantly improved, the ventilation and filtering efficiency of the filter device are improved, and the filter device can continuously and stably play a good purification role. The arrangement of the driving assembly enables the dust removal assembly to automatically rotate relative to the filter device, which has high automation and reduces the labor intensity of the operator. The air outlet of the dust removal assembly is arranged towards the filter element, which enhances the dust blowing effect and helps to maintain the cleanliness and efficient operation of the filter element. The filter element is arranged around the dust removal assembly, so that the high-pressure air flow entering the dust removal assembly output can fully contact the filter element, thereby further improving the dust removal efficiency.

The driving motor, the driving gear and the driven gear form an efficient and reliable power transmission system, thereby driving the rotation of the dust removing assembly and the cover plate assembly.

The pressure sensor can detect the gas pressure in the gas storage cavity. When the gas pressure in the gas storage cavity is sufficient, the controller drives the dust removal assembly to rotate at a higher second rotating speed, so as to realize intermittent high-pressure airflow delivery, thereby ensuring the efficient dust removal of the dust removal assembly on the second filter assembly.

The arrangement of the gas storage cavity 203 enables the external high-pressure air flow to be temporarily stored, thereby ensuring that there is sufficient gas source to blow off the dust on the filter piece 223. The gas storage cavity 203 is capable of being in communication with the second filter cavity, so that the air flow in the gas storage cavity 203 can be delivered into the second filter cavity to blow off the dust adhered in the second filter cavity.

[0051] As Figures 6-8In addition to the features of the above embodiments, the present embodiment is further limited as shown: further comprising a dust removal assembly 3, a driving assembly 4 and a cover plate assembly 5, the dust removal assembly 3 is arranged on the gas storage shell 222 and extends to the inside of the filter element 223, the filter element 223 is arranged around the dust removal assembly 3, the dust removal assembly 3 can rotate relative to the filter device 2, the dust removal assembly 3 is provided with a first air inlet 301 and an air outlet 303, the first air inlet 301 can communicate with an external air source, the air outlet 303 is arranged towards the filter element 223, the dust removal assembly 3 is provided with a first gas conveying passage 302, the first air inlet 301, the first gas conveying passage 302 and the air outlet 303 are sequentially communicated, the driving assembly 4 is arranged on the gas storage shell 222, the driving assembly 4 is in transmission connection with the dust removal assembly 3, the driving assembly 4 can drive the dust removal assembly 3 to rotate relative to the filter device 2, the cover plate assembly 5 is arranged on the driving assembly 4, the driving assembly 4 can drive the cover plate assembly 5 to rotate relative to the filter device 2, the cover plate assembly 5 can rotate at least a first angle and a second angle relative to the filter device 2, when the cover plate assembly 5 rotates at the first angle, the cover plate assembly 5 closes the first air inlet 301, when the cover plate assembly 5 rotates at the second angle, the first air inlet 301 communicates with the external air source. By the high-pressure gas flow sequentially passing through the first air inlet 301, the first gas conveying passage 302 and the air outlet 303 and being output towards the filter device 2, the dust particles attached to the filter device 2 are efficiently blown off, and the dust cleaning efficiency is improved. The dust removal assembly 3 can rotate relative to the filter device 2 under the action of the driving assembly 4, and multi-angle dust blowing can be realized. This design ensures that dust particles in all directions on the filter device 2 can be blown off, further enhances the cleaning effect, and reduces the possibility of dust residue. The cover plate assembly 5 can close or open the first air inlet 301, thereby realizing intermittent air supply to the dust removal assembly 3, so that the dust removal assembly 3 sprays intermittent gas flow to the filter device 2, which is conducive to further improving the dust removal effect. This intermittent working mode also realizes effective use of energy. Since the dust particles can be effectively cleaned from the filter device 2 in time, the dust accumulated on the filter device 2 is significantly improved, the ventilation and filtering efficiency of the filter device 2 are improved, and the filter device 2 can continuously and stably play a good purification role. The arrangement of the driving assembly 4 enables the dust removal assembly 3 to automatically rotate relative to the filter device 2, which has high automation and reduces the labor intensity of the operator. The air outlet 303 of the dust removal assembly 3 is arranged towards the filter element 223, which enhances the dust blowing effect and helps to maintain the cleanliness and efficient operation of the filter element 223.

[0052] As Figure 13 and Figure 14 shown, in addition to the features of the above embodiments, this embodiment is further defined as: the driving assembly 4 comprises a driving motor 41, a driving gear 42 and a driven gear 43, the driving motor 41 is arranged on the filter device 2, the driving gear 42 is in transmission connection with the driving motor 41, the driven gear 43 is arranged on the dust removal assembly 303, the driven gear 43 is in meshing with the driving gear 42, the driven gear 43 is provided with a second air inlet 401 in communication with the first air inlet 301, the second air inlet 401 can be in communication with an external air source, the cover plate assembly 5 is arranged on the driving gear 42, the driving gear 42 can at least drive the cover plate assembly 5 to rotate by a first angle and a second angle relative to the filter device 2, when the cover plate assembly 5 rotates by the first angle, the cover plate assembly 5 closes the second air inlet 401, when the cover plate assembly 5 rotates by the second angle, the second air inlet 401 is in communication with the external air source. The arrangement of the driving motor 41, the driving gear 42 and the driven gear 43 forms an efficient and reliable power transmission system, thereby driving the rotation of the dust removal assembly 3 and the cover plate assembly 5. This design ensures the stability and reliability of power transmission. The intermittent closing and communication of the second air inlet 401 is realized by the rotation of the cover plate assembly 5. When the cover plate assembly 5 rotates by the first angle, the second air inlet 401 is closed, and the dust removal assembly 3 stops blowing air; when the cover plate assembly 5 rotates by the second angle, the second air inlet 401 is communicated, and the dust removal assembly 3 starts blowing air. This optimized air flow control mechanism realizes intermittent blowing and dust removal, improves the dust removal efficiency and reduces the energy consumption.

[0053] In addition to the features of the above embodiments, this embodiment is further defined as: the number of cover plate assemblies 5 is multiple, multiple cover plate assemblies 5 are arranged on the driving gear 42 and located on the side of the driving gear 42 away from the driving motor 41, and multiple cover plate assemblies 5 are arranged in a circumferential direction of the driving gear 42. The uniform arrangement of multiple cover plate assemblies 5 helps to optimize air flow distribution, so that the air flow generated by the blowing assembly can act more uniformly on the filter device 2. This uniform air flow distribution helps to improve the dust removal efficiency of the filter device 2 and reduce the possibility of local dust accumulation of the filter device 2.

[0054] As Figure 8 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further includes a bearing assembly 44, which is disposed on the driven gear 43 and / or the dust removal assembly 3, and is located between the driven gear 43 and the dust removal assembly 3. The bearing assembly 44 improves the stability of the connection between the driven gear 43 and the dust removal assembly 3. Furthermore, the bearing assembly 44 helps to improve the rotational accuracy of the system.

[0055] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second air inlet 401 is arranged opposite to the first air inlet 301.

The pressure sensor 6 is disposed on the gas storage housing 222 and communicates with the gas storage chamber 203. The controller is electrically connected to both the pressure sensor 6 and the drive assembly 4. When the pressure sensor 6 detects that the gas pressure in the gas storage chamber 203 is lower than a preset value, the pressure sensor 6 transmits a first pressure signal to the controller, and the controller transmits a first control signal to the drive assembly 4. The drive assembly 4 drives the dust removal assembly 3 to rotate at a first speed according to the received first control signal. When the pressure sensor 6 detects that the gas pressure in the gas storage chamber 203 is higher than the preset value, the pressure sensor 6 transmits a second pressure signal to the controller, and the controller transmits a second control signal to the drive assembly 4. The drive assembly 4 drives the dust removal assembly 3 to rotate at a second speed, which is greater than the first speed, according to the received second control signal. The pressure sensor 6 can be used to detect the gas pressure in the gas storage chamber 203. When the air pressure in the air storage chamber 203 is sufficient, the controller drives the dust removal component 3 to rotate at a higher second speed, achieving rapid intermittent high-pressure airflow delivery, thereby ensuring efficient dust removal of the second filter component 22 by the dust removal component 3. When the air pressure in the air storage chamber 203 is insufficient, the controller drives the dust removal component 3 to rotate at a lower first speed, thus extending the duration of communication between the first air inlet 201 and the air storage chamber 203, ensuring sufficient airflow supply to the dust removal component 3, thereby guaranteeing the dust removal effect. This design achieves precise control of the position of the cover plate component 5, has a high degree of automation, and enables effective utilization of high-pressure airflow.

[0057] likeFigures 9-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the dust removal component 3 includes a rotating shaft assembly 31 and an air jet 32. The rotating shaft assembly 31 is disposed on the filter device 2 and is drivenly connected to the drive assembly 4.

The second air delivery channel 304 communicates with the first air delivery channel 302 and the air outlet 303, respectively. The driving connection between the rotating shaft assembly 31 and the drive assembly 4 ensures that the air jet 32 ​​can rotate at a preset speed and direction, thereby achieving multi-angle dust blowing on the filter device 2. The arrangement of the air jet 32 ​​allows the airflow to be blown towards the filter device 2 at a higher speed and with a stronger impact force, thereby more effectively blowing off dust particles attached to the filter device 2.
