[0002] The rotary vibrating screen is a high-precision fine powder screening machine. In order to further improve the screening efficiency of the rotary vibrating screen, ultrasonic vibration is usually added to the conventional vibrating screen.

[0003] The vibrating screen mesh is usually attached to the mesh frame. The vibration generated by the ultrasonic transducer with a frequency of 34,000 Hz directly acts on the mesh frame, causing the mesh frame to produce high-frequency vibration with a small amplitude, and the mesh mesh also vibrates accordingly. However, the existing transducer ultrasonic mesh frame has the following disadvantages:

[0004] The profile grid of the existing transducer ultrasonic grid is often connected to the ultrasonic ring through a square tube support. The hollow rectangular tube is used as the support between the ultrasonic ring and the profile grid to improve the elasticity of the structure, that is, to reduce the structural rigidity. This external transducer structure is applicable to materials with small specific gravity, but when applied to materials with large specific gravity, weld cracking and grid breakage accidents are prone to occur, and it cannot be scaled up;

[0005] The existing transducer ultrasonic grid is often connected to the screen by bonding, which makes the installation of the screen not firm enough and is easy to fall off during vibration. Utility Model Content

[0009] As a preferred technical solution of the utility model, a plurality of circular holes are provided on the surface of the support plate and the surface of the support ribs, and the circular holes provide the support plate and the support ribs with both strength and flexibility.

[0010] As a preferred technical solution of the utility model, an extension part is provided at the bottom of the profile grid, and the provided extension part is more convenient for the installation of the ultrasonic grid.

[0012] As a preferred technical solution of the utility model, an adaption groove is provided at one end of the support plate, and the provided adaption groove makes the end of the support plate fit more closely with the attachment plate.

[0013] As a preferred technical solution of the utility model, one end of the threaded rod away from the clamping block is fixedly connected to a rotating block. The rotating block is used to drive the threaded rod to rotate.

[0014] As a preferred technical solution of the utility model, the top and bottom of the inner wall of the mounting seat are provided with a slide groove, the inner walls of the two slide grooves are slidably connected with sliders, and the two sliders are respectively fixedly connected to the top and bottom of the clamping block.

[0015] As a preferred technical solution of the utility model, the surface of the clamping block is provided with anti-skid teeth, which make the clamping block more stable when clamping the screen.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By placing the ultrasonic transducer outside the rotary vibrating screen and not participating in the vibration, the cracking phenomenon of the weld at the connection between the ultrasonic transducer and the grid frame due to the high vibration frequency can be fundamentally solved. The ultrasonic ring is connected to each other or to the profile grid through multiple support plates and support ribs, and each support plate is perforated, so that the structure takes into account both strength and flexibility.

[0027] When in use, the ultrasonic transducer is outside the rotary vibrating screen and does not vibrate with the grid, but transmits the ultrasonic vibration to the ultrasonic ring through two ultrasonic guide rods. This can fundamentally solve the cracking phenomenon caused by the weld at the connection between the ultrasonic transducer and the grid due to excessively high vibration frequency. In order to improve the vibration strength of the screen, the grid adopts a symmetrical design of binary ultrasonic rings, each connected to a conduction rod, and the ultrasonic rings are connected to each other or to the profile grid 1 through multiple support plates 2 and support ribs 4. The binary symmetrical arrangement of the ultrasonic rings is conducive to the development of large-scale ultrasonic vibration of the rotary vibrating screen;

In order to improve the vibration strength of the screen, the grid frame adopts a symmetrical design of binary ultrasonic rings, each of which is connected to a conduction rod, and the ultrasonic rings are connected to each other or to the profile grid frame 1 through multiple support plates 2 and support ribs 4, wherein each support plate 2 is perforated, so that the structure has both strength and flexibility, and the binary symmetrical arrangement of the ultrasonic rings is conducive to The large-scale development of ultrasonic vibration of rotary vibrating screen finally takes into account the screening performance and long service life.
