Technical Field

[0001] The present invention relates to the technical field of ultrasonic vibration plates, and in particular to an ultrasonic vibrator reinforcement device. Background Art

[0002] For the application of ultrasound in the field of metallurgy, the physical properties of ultrasound are mainly used to improve the process parameters of leaching, purification, mineral processing, etc. in the metallurgical process. Ultrasonic waves are mainly provided by ultrasonic vibration plates. Ultrasonic vibration plates generally include a vibration plate body and a plurality of vibrators arranged on the vibration plate body. After the vibrator is powered on, the vibrator will generate high-frequency vibrations, thereby applying ultrasonic waves to the solution.

[0003] In the prior art, the vibrator is fixed by screws welded to the vibration plate body, but because the ultrasonic vibration plate is immersed in a high-temperature solution for a long time and the vibrator itself generates high-frequency vibrations, it is easy for the welding screws to loosen or even cause the vibrator to fall off. The fallen vibrator may also collide with other vibrators. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an ultrasonic vibrator reinforcement device.

[0005] The objective of the present invention is achieved through the following technical solutions: An ultrasonic vibrator reinforcement device, the vibrator is fixed in the installation cavity of the vibration plate body, the reinforcement device comprises a fixing piece arranged in the installation cavity and located at the top of the vibrator, and the fixing piece can act on the vertical resistance of the vibrator.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 5 As shown, an ultrasonic vibrator reinforcement device includes a fixing member 1 arranged in a mounting cavity 18 of a vibration plate body 17, and the fixing member 1 is located on the top of the vibrator 19 and can act on the vertical resistance of the vibrator 19. The vibrator 19 is thus less likely to move axially and has a more stable fixed state. Even when the bolts used to fix the vibrator 19 fail, the fixing member 1 can still restrain the vibrator 19, so that the vibrator 19 will not move at will and damage other vibrators 19 that are operating normally.

[0020] like Figure 1 , Figure 2 As shown, in some embodiments, the vibrator 19 itself is a tapered shape with a gradually expanding diameter, and the fixing member 1 may include a fixing baffle 2. Specifically, a through hole 3 is provided on the fixing baffle 2, and the vibrator 19 is arranged in the through hole 3. The fixing baffle 2 abuts against the side wall of the vibrator 19, so that the vibrator 19 is not easy to move upward and is subject to the expected resistance.

[0021] For example, the fixed baffle 2 can be fixed in the installation cavity 18 by welding. In other schemes, a fixed screw 6 can also be provided in the installation cavity 18, and the fixed baffle 2 can be detachably sleeved on the fixed screw 6. Of course, the vibrator 19 is still accommodated in the through hole 3 of the fixed baffle 2, and then the fixed baffle 2 can be pressed on the vibrator 19 by the fixing nut 7. Preferably, two screws can be provided to achieve a more stable pressing effect.

[0022] like Figure 3As shown, in other embodiments, the fixing member 1 may further include a fixing gasket 4 disposed on the top surface of the vibrator 19, and the size of the fixing gasket 4 is preferably completely clamped between the vibrator 19 and the vibration plate body 17. Of course, the fixing gasket 4 can be fixed to the vibration plate body 17 by bolting or welding. In a possible approach, the fixing gasket 4 can also be integrally formed with the vibration plate body 17, for example, by milling.

[0023] like Figure 4 , Figure 5 As shown, the fixing member 1 may further include a fixing spring 5 disposed on the top surface of the vibrator 19. Similar to the fixing gasket 4, the fixing spring 5 is also pressed between the vibrator 19 and the vibration plate body 17. Similarly, the fixing spring 5 may also be fixed to the vibration plate body 17 by welding or bolting.

[0024] For example, the fixing spring 5 may preferably be a thermosensitive spring, which is a special spring that combines the characteristics of thermosensitive materials and springs and can produce corresponding deformation or elastic force changes when the temperature changes. The thermosensitive spring is a prior art and will not be described in detail in the present invention. It only needs to be able to shrink and separate from the vibrator 19 in a natural state, and expand and act as a vertical resistance to the vibrator 19 in a heated state.

[0025] Therefore, when the ultrasonic vibration plate is running in a high-temperature solution, the thermal spring will expand under the action of heat and limit the axial movement of the vibrator 19; when not in use, the thermal spring will re-contract and separate from the vibrator 19. On the one hand, the separation of the fixing device and the vibrator 19 will make it easier to maintain or replace the vibrator 19; on the other hand, this separation can also make the vibrator 19 less likely to be subjected to undesirable abutment forces for a long time (mainly when the ultrasonic vibration plate is not in use), and the life of the vibrator 19 is longer.

[0026] In a preferred example, an abutment block 8 is provided at the end of the fixed spring 5, and the abutment block 8 is specifically configured as a mounting groove 9 is opened on the top surface, and a connecting plate 10 is elastically provided in the mounting groove 9, and the fixed spring 5 is fixed to the connecting plate 10. In addition, a plug rod 11 extending into the mounting groove 9 is slidably adapted on the side wall of the abutment block 8, and a return spring 16 is connected to the plug rod 11; a locking rod 13 that can be inserted into the sliding groove of the plug rod 11 is slidably adapted on the top surface of the abutment block 8.

[0027] More specifically, a locking groove 14 is provided on the side wall of the insertion rod 11, and an abutment rod 15 is provided on the top side wall of the locking rod 13. A slot 12 is correspondingly provided on the inner wall of the installation cavity 18. The present invention may have the following operation process: S1, the fixing spring 5 is in a contracted state, and the abutment block 8 is separated from the vibrator 19; S2. As the solution reaction proceeds, the fixed spring 5 expands due to heat and drives the abutment block 8 to abut against the vibrator 19 as a whole; S3, the fixing spring 5 continues to expand. At this time, since the abutment block 8 cannot be pushed out further, the fixing spring 5 will push the connecting plate 10 downward. During the downward pressure, the connecting plate 10 can push out the insertion rod 11 and insert it into the slot 12, and the locking rod 13 will be inserted into the locking groove 14. S4. As the solution reaction is completed, the fixing spring 5 contracts again. At this time, due to the limiting effect of the insertion rod 11 and the slot 12, the abutment block 8 cannot be driven to rise. Therefore, the fixing spring 5 will pull the connecting plate 10 up, and the connecting plate 10 will conflict with the abutment rod 15, thereby driving the locking rod 13 to be pulled out of the locking groove 14.

[0028] It can be understood that in the above S4, the temperature drop does not cause the abutment block 8 to rise immediately. Only when the connection plate 10 pulls the locking rod 13 out of the locking groove 14, the insertion rod 11 can be pulled out of the slot 12, and then the abutment block 8 can be separated from the vibrator 19 upward under the elastic force. This is particularly advantageous when the solution reaction is almost completed and the vibrator 19 still needs to work, so that the abutment block 8 can act on the vibrator 19 during the operation of the vibrator 19 to provide a stable vertical resistance.

[0029] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
