[0017] like Figs. 1-2 As shown, this utility model provides a novel dry ultrasonic dust collector, including a housing 1, a front cover 4 and a rear cover 5 respectively located at the front and rear ends of the housing, a blowing flange joint 2 and a suction flange joint 3 located directly above the housing 1, and a dust collection system 6 located directly below the housing 1. The housing 1 contains an air inlet chamber 13 and an air outlet chamber. The blowing flange joint 2 communicates with the air inlet chamber 13, and the suction flange joint 3 communicates with the air outlet chamber. The ultrasonic dust collector also includes sealing plates 7. Elastic deformation sealing plates 7 are provided between the front cover 4 and the housing 1, and between the rear cover 5 and the housing 1, respectively covering the front and rear ends of the housing 1. By adding sealing plates 7 structures that can elastically deform under pressure to the front and rear ends of the housing 1, and sealing them with the front cover 4 and the rear cover 5 respectively, the sealing effect of the product can be enhanced. Positioning the blowing flange joint 3 and the suction flange joint 3 at the upper end of the housing 1 reduces the pressure on the front cover 4 and the rear cover 5, making them less prone to deformation.

[0018] The blower flange 2 and the suction flange 3 are arranged in a front-to-back direction. The top wall of the housing 1 has an air inlet 11 and two air outlets 12. The blower flange 2 covers the air inlet 11, and the suction flange 3 covers the two air outlets 12. The blower flange 2 and the suction flange 3 are arranged one after the other on the top wall of the housing 1. This design saves the product's footprint to the greatest extent. Since both the blower flange 2 and the suction flange 3 are arranged in a vertical direction, it is convenient to connect a small external air supply device, which is suitable for some applications with limited space.

[0019] There are two air outlet chambers: a left air outlet chamber 14 located to the left of the air inlet chamber 13 and a right air outlet chamber 15 located to the right of the air inlet chamber 13. The air inlet chamber 13 is connected to the air inlet 11, and the left air outlet chamber 14 and the right air outlet chamber 15 are connected to the two air outlets 12, respectively. The main function of the air inlet chamber 13 is to concentrate the air supplied by the blower flange connector 2 into the air inlet chamber 13 to form a relatively strong airflow. The main function of the left air outlet chamber 14 and the right air outlet chamber 15 is to adsorb the particles flowing in the air returned by the dust removal system 6.

[0020] The bottom wall of the cover 1 is provided with three through holes, which are respectively located in the air inlet chamber 13, the left air outlet chamber 14 and the right air outlet chamber 15. The air blown by the air blowing flange joint 2 flows to the dust removal system 6 below through the through hole of the air inlet chamber 13. Under the suction of the air suction flange joint 3, the air treated by the dust removal system 6 flows to the left air outlet chamber 14 and the right air outlet chamber 15 through the through holes of the left air outlet chamber 14 and the right air outlet chamber 15 respectively.

[0021] The dust removal system 6 comprises a wind knife head 61 and two air collecting sheets respectively arranged on the left and right sides of the wind knife head 61, the two air collecting sheets are a left air collecting sheet 62 and a right air collecting sheet 63 respectively, the wind knife head 61 forms a left air collecting cavity 64 and a right air collecting cavity 65 with the left air collecting sheet 62 and the right air collecting sheet 63 respectively, the wind knife head 61 is located directly below the air inlet chamber 13 and communicates with the air inlet chamber 13, the left air outlet chamber 14 communicates with the left air collecting cavity 64, and the right air outlet chamber 15 communicates with the right air collecting cavity 65. The left air collecting cavity 64 and the right air collecting cavity 65 mainly function to return the air containing particles after dust removal of the wind knife head 61.

[0022] The wind knife head 61 comprises, from top to bottom, a ventilation groove 611, a steady flow channel 612 and a wind knife opening 613, the flow area of the ventilation groove 611 and the wind knife opening 613 is greater than that of the steady flow channel 612, and the air inlet chamber 13, the ventilation groove 611, the steady flow channel 612 and the wind knife opening 613 communicate with each other in sequence. Because the air flows from the air inlet chamber 13 to the ventilation groove 611 of the wind knife head 61 through the through hole, and then passes through the narrow steady flow channel 612, the design structure realizes acceleration of the high-speed airflow from the ventilation groove 611 to the wind knife opening 613 by changing the cross-sectional area of the air flow channel.

[0023] Preferably, the wind knife opening 613 is a concave circular arc surface upward. The design of the circular arc is more suitable for the dust removal product to be applied, increases the dust removal area and improves the dust removal efficiency, and also avoids that the air containing particles is rapidly discharged to the external environment after the dust removal treatment of the wind knife opening 613.

[0024] The above is the preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the present application, and these improvements and refinements are also regarded as the protection scope of the present application.
