[0004] The existing ultrasonic dust removal equipment only keeps the airflow under a pressure state to wash away the dust on the material during dust removal, and it is difficult to clean some sticky dust. In addition, the existing equipment also performs dust removal operations on the surface of the substrate by water washing, wiping, etc. However, many substrates are special. After the contact dust removal operation, the surface of the substrate is damaged. For example, wiping will cause scratches, and water washing will change the properties of the material, thereby increasing the cost of use. Summary of the invention

[0010] Preferably, a filter chamber is opened on the top of the box body, the inside of the filter chamber is connected to the filter element through fasteners, one end of a connecting pipe is provided on one side of the filter element, the end of the connecting pipe away from the filter element is connected to the high-pressure fan through fasteners, and the bottom fasteners of the reflux interface are connected to the shell.

[0011] Preferably, a fastener on one side of the filter chamber is connected to the filter screen, and one end of the filter screen has an end of the return pipe away from the return interface, and the return pipe is connected to the filter chamber in a penetrating manner.

[0012] Preferably, the air inlet interface is connected to the interior of the shell through an air inlet port, and the reflux interface is connected to the interior of the shell through an air outlet port. The air inlet port and the air outlet port are also provided on the amplifier board.

[0013] Preferably, the bottom of the amplifier plate is connected to the extrusion plate by fasteners, the extrusion plate is distributed in a mirror image at the bottom of the amplifier plate, the middle of the amplifier plate runs through the middle of the extrusion plate, and a reflux groove is opened on the inner side of the extrusion plate.

[0015] Preferably, the outer wall of the drum is connected to the material in a tightened form, a positive pressure chamber is opened on the inner side of the partition, a negative pressure chamber is opened on the outer side of the partition, and the negative pressure chambers are symmetrically distributed inside the shell.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] First, the present invention can perform non-contact dust removal on the material by arranging an amplitude plate and a positive pressure chamber. When the material is moved to the bottom of the shell by the drive of the roller, the high-pressure fan is turned on, and the airflow enters the inside of the air inlet interface through the air inlet pipe, and the airflow enters the positive pressure chamber inside the shell through the air inlet joint for pressure stabilization. After sufficient pressure, the partition guides the airflow entering the shell through the air inlet hole into the circular groove of the amplifier plate, and the circular groove guides the airflow into the triangular groove at the bottom, forming a high-frequency vibrating airflow to clean the surface of the material. The high-frequency vibrating airflow impacts the material to peel off the dust on the material. The airflow and the peeled dust are drawn into the reflux groove by the high-pressure fan, and enter the negative pressure chamber of the shell through the reflux groove, so as to achieve non-contact cleaning of the material, prevent contact cleaning from easily damaging the material, and effectively reduce the cost of use. At the same time, the dust solidified on the material can be washed away by the cleaning of the vibrating airflow.

[0018] Secondly, the present invention provides a filter chamber and a return pipe, so that the air drawn by the high-pressure fan can be circulated. The dusty air enters the return pipe through the shell, and the return pipe transports the dusty air to the filter chamber. The connecting pipe draws the air inside the filter chamber inside the filter element to filter the dusty air, leaving the dust on the filter element. The remaining air is output again after circulation of the high-pressure fan, thereby preventing the air from being directly discharged into the workshop, which may easily disrupt the airflow in the workshop. At the same time, it prevents the dusty air from being directly discharged into the workshop, which reflects the practicality of this device. BRIEF DESCRIPTION OF THE DRAWINGS

The shell body 4 is located at the upper and lower ends of the outer side of the partition 14. The exhaust port 19 is opened at the upper and lower ends of the shell body 4. The bottom of the shell body 4 is connected to the top of the amplifier plate 15 through fasteners, a circular groove 20 is opened on the inner side of the amplifier plate 15, and a triangular groove 21 is opened below the circular groove 20, and the circular groove 20 and the triangular groove 21 are interconnected.

[0033] Specifically, a filter chamber 24 is opened on the top of the box body 1, and the inside of the filter chamber 24 is connected to the filter element 7 through fasteners. One end of a connecting pipe 10 is provided on one side of the filter element 7. The end of the connecting pipe 10 away from the filter element 7 is connected to the high-pressure fan 8 through fasteners, and the bottom fasteners of the reflux interface 11 are connected to the shell 4.

[0034] Through the above technical solution, this device can perform contactless dust removal on a variety of different materials such as optical film dust removal, optical glass dust removal, new energy coating dust removal process, mold cutting dust removal, semiconductor dust removal, etc.

[0035] Specifically, a fastener on one side of the filter chamber 24 is connected to the filter screen 9 , and one end of the filter screen 9 is provided with an end of the return pipe 6 away from the return interface 11 , and the return pipe 6 is connected to the filter chamber 24 in a penetrating manner.

[0036] Through the above technical solution, the filter chamber 24 is used to filter the air after the material 3 is cleaned, so as to prevent the air containing dust from being directly discharged to the outside and inhaled by the staff.

[0037] Specifically, the air inlet interface 12 is connected to the interior of the shell 4 through the air inlet port 18 , and the reflux interface 11 is connected to the interior of the shell 4 through the air outlet port 19 . The air inlet port 18 and the air outlet port 19 are also provided on the amplifier board 15 .

[0038] Through the above technical scheme, the air inlet 18 is located in the middle position of the two partitions 14, the bottoms of the two partitions 14 are relatively inclined, the exhaust port 19 is located on the outside of the two partitions 14, and the exhaust port 19 and the air inlet 18 are respectively opened at the top and bottom of the shell 4.

[0044] Through the above technical solution, the roller 25 can be designed into different shapes according to the different materials 3 to be cleaned, which is convenient for cleaning materials 3 of different materials. The positive pressure chamber is used to pressurize the airflow so that the airflow can wash away the dust on the material.

[0045] When in use, first, turn on the high-pressure fan 8, the airflow enters the interior of the air inlet interface 12 through the air inlet pipe 5, and the airflow enters the positive pressure chamber inside the shell 4 through the air inlet joint for pressure stabilization. After sufficient pressure, the partition 14 guides the airflow entering the shell 4 into the circular groove 20 of the amplifier plate 15 through the air inlet hole, and the circular groove 20 guides the airflow into the triangular groove 21 at the bottom, forming a high-frequency vibrating airflow to clean the surface of the material 3. The high-frequency vibrating airflow impacts the material 3, so that the dust on the material 3 is stripped off, and the airflow and the stripped dust are drawn into the reflux groove 22 by the high-pressure fan 8, and enter the negative pressure chamber 17 of the shell 4 through the reflux groove 22. The dusty air enters the interior of the reflux pipe 6 through the shell 4, and the reflux pipe 6 transports the dusty air to the inside of the filter chamber 24.
