[0054] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0055] See Figures 1 to 6 As shown;

[0056] This embodiment discloses a high-efficiency dust recovery device, which includes:

[0057] Large box 1 and small box 2 located at one end of large box 1;

[0058] The small box 2 is equipped with an exhaust fan 201, and the exhaust end of the exhaust fan 201 faces the large box 1. An exhaust hole 102 is provided at the position where the large box 1 and the small box 2 meet.

[0059] The air intake end of the large housing 1 is equipped with a filter component, and impurities in the gas entering through the air intake end of the large housing 1 are filtered by the filter component.

[0060] The large housing 1 has a dust removal hood 6 that is connected to the filter assembly, and the output end of the dust removal hood 6 is connected to a dust collection box 9 through a ventilation pipe 8.

[0061] Dust collection box 9 is located in the large box 1 near the air extraction port 102;

[0062] The recycling device also includes:

[0063] An ultrasonic atomizer 4 is located at the top of the large housing 1, and the ultrasonic atomizer 4 is connected to the filter assembly via a nozzle 408 extending into the interior of the large housing 1.

[0064] Specifically, this embodiment discloses a dust recovery device with a split structure design, comprising a large box 1 and a small box 2. The small box 2 is the power source for airflow, i.e., an exhaust fan 201 is installed inside the small box 2, which acts on the large box 1 to create airflow. The large box 1 of this embodiment integrates a filter assembly, a dust collection hood 6, a ventilation duct 8, and a dust collection box 9. The filter assembly, dust collection hood 6, ventilation duct 8, and dust collection box 9 are arranged according to the airflow direction and are connected in sequence. An ultrasonic atomizer 4 is installed at the upper end of the large box 1 of this embodiment. The ultrasonic atomizer 4 acts inside the filter assembly, using charged spray water mist to combine with ultrafine dust to form larger agglomerated particles, further improving the dust recovery rate.

[0065] Preferably, in this embodiment, the dust collection box 9, the ventilation pipe 8, and the air extraction hole 102 are all open at one end;

[0066] One end of the dust collection box 9 is connected to the ventilation pipe 8, and the other end of the dust collection box 9 is provided with a filter layer 901 between it and the inner wall of the large box 1. The airflow of the exhaust fan 201 in the small box 2 can pass through the filter layer 901.

[0067] The filter layer designed at the air extraction port 102 of the dust collection box 9 and the large box 1 can be any filter structure that can both ventilate and adsorb dust, such as non-woven fabric. Its design purpose is to not affect ventilation, but to assist the dust collection box 9 in recovering dust, while also preventing the airflow from bringing dust into the small box 2.

[0068] Preferably, the filter assembly of this embodiment includes a filter structure 3 disposed at the air inlet end of the large housing 1; and a collector 5 connected to the filter structure 3. The collector 5 is divided into an air inlet 501 and an air outlet 502. The air inlet 501 of the collector 5 is connected to the filter structure 3, and the air outlet 502 of the collector 5 is connected to the dust collector 6. The surface of the dust collector 6 is evenly distributed with a plurality of air vents.

[0069] More preferably, in this embodiment, the edge of the air inlet end of the large housing 1 is configured as a sloped structure 103. This sloped structure 103 can guide the airflow, allowing it to act on the filter structure 3 and enter the collector 5.

[0070] More preferably, in this embodiment, the air inlet 501 of the collector 5 is configured as an flared structure with the opening gradually increasing from the end near the air outlet 502 to the end near the filter structure 3; secondly, in this embodiment, the air outlet 502 is configured as a constricted structure with the cross-sectional size gradually decreasing from the end near the air inlet 501 to the end near the dust collector 6; the air inlet 501 and the air outlet 502 are connected by a straight pipe 503.

[0071] Airflow enters the air inlet of the large housing 1 through the action of the exhaust fan 201. At this time, large particles in the airflow, such as industrial waste, are filtered out by the filter structure 3 to prevent them from clogging the device, while small particles such as dust enter the device and, after passing through the filter structure 3, enter the collector 5. In this embodiment, the collector 5 adopts an air inlet 501 with a flared structure and an air outlet 502 with a constricted structure. The air inlet 501 of this embodiment is matched with the nozzle 408 of the ultrasonic atomizer 4. The charged water mist generated by the ultrasonic atomizer 4 combines with the ultrafine dust to form larger agglomerated particles, which facilitates the recovery of ultrafine dust.

[0072] Preferably, the ultrasonic atomizer 4 in this embodiment includes:

[0073] Atomizer housing 401;

[0074] A water storage tank 403 is formed inside the atomizer housing 401, and the water storage tank 403 has a grid 405 inside;

[0075] The piezoelectric ceramic 404 is located at the bottom of the water storage tank 403;

[0076] A fan 402 is also installed inside the atomizer housing 401;

[0077] The atomizer housing 401 is provided with a nozzle pipe 406 at one end relative to the fan 402, and an electrode 407 is provided inside the nozzle pipe 406. The electrode 407 consists of two parallel copper plates.

[0078] The nozzle pipe 406 passes through the large housing 1 and extends to the upper part of the air intake 501.

[0079] The control circuit of the ultrasonic atomizer 4 in this embodiment is detailed in [link to example]. Figures 4 to 6 In this embodiment, the atomizing device 4 consists of a fan 402, a water storage tank 403, a piezoelectric ceramic 404, a grille 405, an electrode 407, and an atomizer housing 401. The fan 402 blows out mist, and the piezoelectric ceramic 404 performs ultrasonic atomization below the water storage tank 403. In addition, the grille 405 in this embodiment prevents water droplets from splashing into the fan 402 and the dust removal device, and the electrode 407 is installed in the nozzle pipe 406. In this embodiment, the electrode 407 applies an electric field at the nozzle 408 to polarize and charge the water mist.

[0080] More preferably, the piezoelectric ceramic 404 in this embodiment is a cylindrical lead titanate (PZT) material, with a diameter similar to the inner diameter of the water storage tank 403; secondly, the electrode 407 in this embodiment is made of copper, and a uniform electric field is formed between the two parallel copper sheets; as an extension, the atomizing device in this embodiment requires a control circuit and an external DC power supply, the piezoelectric ceramic 404 needs an oscillation circuit to control its vibration, and other electrical appliances can be adjusted to the corresponding voltage through the control circuit. This enables the ultrasonic atomizer 4 to generate charged water mist, which then acts on ultrafine dust.

[0081] Preferably, in this embodiment, a partition 7 is installed between the dust removal hood 6 and the ventilation pipe 8, and the partition 7 is a mesh plate with evenly distributed ventilation holes;

[0082] The three sides of the partition 7 extend to the corresponding inner wall of the large box 1, and the side of the partition 7 closest to the collector 5 extends to the air intake 501.

[0083] The partition 7 divides the interior of the large box 1 into two external processing spaces 101, one above the other. The airflow from the dust collection box 9 and the dust removal hood 6 flows in the external processing space 101 and carries the dust through the partition 7.

[0084] During operation, the airflow that initially filters out larger impurities enters the collector 5, and its velocity decreases after entering the dust collector 6. The dust settles into the dust collection box 9 under the influence of gravity. In this embodiment, the remaining gas is filtered through the filter layer inside the large box 1 before entering the small box 2 and being discharged to the outside of the device.

[0085] The high-efficiency dust recovery device provided by this utility model, as described above, has the following beneficial effects:

[0086] The recycling device of this utility model effectively reduces the airflow velocity and achieves the settling of large particles and secondary interception of micro dust through the structure of dust hood 6 and baffle 7, effectively preventing dust backflow; at the same time, the designed ultrasonic atomizer 4 promotes the agglomeration of micron-sized dust in the airflow, significantly improving the capture efficiency of the filter material.

[0087] The recycling device of this utility model adopts a split double-box structure of large box 1 and small box 2, so that each unit can be disassembled and maintained independently, reducing maintenance difficulty and cost.

[0088] The filter structure 3 at the front end of the recycling device of this utility model can prevent pipe blockage. At the same time, the small box 2 is provided with heat dissipation holes for the exhaust fan 201 to dissipate heat. Combined with the forced convection of the exhaust fan 201, the equipment can be continuously and stably operated.

[0089] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
