DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: an ultrasonic cyclone filter, comprising a cylindrical shell 11 and a top cover 13 fixed on the top surface of the cylindrical shell 11, a sewage pipe 12 is arranged at the bottom of the cylindrical shell 11, a cyclone liquid inlet 18 communicating with the inner side of the cylindrical shell 11 is arranged on one side of the top of the cylindrical shell 11, an annular support 15 is fixed on the inner side of the cylindrical shell 11, and a filter screen 14 is installed above the annular support 15, an ultrasonic transducer 21 is installed on the top surface of the top cover 13, and the model of the ultrasonic transducer 21 is KDYA-300-050AB-CTY, the ultrasonic transducer 21 can generate regular vibrations greater than 25kHz under electric field excitation. A vibration rod 23 is connected to the bottom surface of the ultrasonic transducer 21, and the bottom end of the vibration rod 23 penetrates the inner side of the cylindrical shell 11 and is connected to the filter 14. The vibration rod 23 is a passive device, which changes the amplitude of the vibration input by the ultrasonic transducer 21 and then transmits it to the filter 14, completing the impedance transformation. The amplitude of the ultrasonic wave can reach 50μm. A plurality of support springs 24 are connected between the bottom end of the filter 14 and the top surface of the annular support 15.

[0020] The top end of the support spring 24 is welded and fixed to the bottom end surface of the filter screen 14 , and the bottom end of the support spring 24 is welded and fixed to the top surface of the annular support seat 15 .

[0021] A rod hole 17 corresponding to the vibrating rod 23 is opened on the surface of the top cover 13 to allow the vibrating rod 23 to pass through smoothly.

[0022] A mounting seat 22 is welded and fixed to the outer surface of the bottom end of the ultrasonic transducer 21 , and the mounting seat 22 is fixed to the top surface of the top cover 13 by bolts, so as to achieve stable installation of the ultrasonic transducer 21 .

[0023] In summary, in actual use, when the slag water enters the interior of the cylindrical shell 11 along the tangential direction through the cyclone liquid inlet 18, a cyclone will be formed inside the cylindrical shell 11. Impurities such as slag and suspended solids are precipitated at the lower part along the wall of the cylindrical shell 11 under the action of centrifugal force, gravity and gravity, and are discharged through the sewage pipe 12. In this process, the filter screen 14 will filter the impurities in the water. At the same time, the filter screen 14 is driven by the vibration rod 23 to vibrate at a frequency higher than 20kHz to generate ultrasonic waves. The ultrasonic wave utilizes its cavitation effect in the water. When the sound pressure reaches a certain value, a local temporary negative pressure area will be formed on the surface of the filter screen 14 in the liquid. Countless bubbles are quickly formed and quickly imploded to generate shock waves, such as peeling off the dirt layer, and thus being carried away by the cyclone sewage.

[0024] Example 2

[0025] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the sealing performance of the ultrasonic transducer 21 after installation can be improved by setting a sealing structure.

[0026] Specifically, it also includes a sealing structure, which is arranged between the mounting seat 22 and the top cover 13. The sealing structure includes an annular rubber seat 31 and an annular top protrusion 32. The top surface of the top cover 13 is provided with an annular mounting groove 16 corresponding to the annular rubber seat 31 relative to the outer side of the rod hole 17. The annular rubber seat 31 is glued and fixed to the inner side of the annular mounting groove 16. The top surface of the annular rubber seat 31 is provided with an integrated annular top protrusion 32. Both are made of rubber material and will undergo elastic deformation when squeezed. The bottom surface of the mounting seat 22 is provided with an annular sealing groove 221 corresponding to the annular top protrusion 32. The annular top protrusion 32 is squeezed into the annular sealing groove 221, so that the mounting seat 22 has good sealing performance after being fixed on the top of the top cover 13.

[0027] Among them, the inner wall of the annular rubber seat 31 is provided with an integrated annular inner protrusion 33, both of which are made of rubber material and will undergo elastic deformation when squeezed. The annular inner protrusion 33 is squeezed and contacted with the vibration rod 23, which can further improve the installation sealing of the ultrasonic transducer 21.

[0028] A circular cavity is defined in the annular rubber seat 31 , so that the annular top protrusion 32 and the annular inner protrusion 33 have sufficient deformation space when being squeezed.

[0029] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
