Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic vibration plates, and in particular to an ultrasonic device with an air cooling function. Background Art

[0002] Hydrometallurgy is to contact ore, concentrate or other raw materials with aqueous solution or other liquids, transfer the useful metals in the raw materials into liquid phase through chemical reaction, separate and enrich the useful metals in the liquid phase, and finally recover them in the form of metals or other compounds. Ultrasonic enhanced reaction pools are required in the metallurgical process.

[0003] The role of ultrasound in hydrometallurgical reaction systems is mainly based on the mechanical vibration and cavitation effect it produces. When ultrasound passes through a liquid medium, a series of tiny bubbles are formed, which grow and burst rapidly under the action of ultrasound, generating instantaneous high temperature, high pressure and strong shock waves. These extreme conditions can accelerate the process of chemical reactions and improve reaction rates and efficiency.

[0004] The specific method is: an ultrasonic vibration plate is set in the reaction tank to act on the reaction solution with ultrasonic waves. However, the temperature of the reaction solution is generally 60-90°C, and the vibrator in the ultrasonic vibration plate is easy to heat up, resulting in a shortened service life. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an ultrasonic device with an air cooling function.

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 device with air cooling function includes a plate body 2 with a mounting cavity 1. A plurality of vibrators 3 are arranged side by side in the mounting cavity 1, and the vibrators 3 are prior art, and their working principles and internal specific structures are not described in detail in the present invention. Through the plurality of vibrators 3, the vibration plate can generate ultrasonic waves of sufficient power, for example, to enhance the reaction of the solution.

[0020] See also Figure 2 The plate body 2 is provided with a ventilation pipe 4 extending through the installation cavity 1, and a plurality of air outlets 5 are provided on the side wall of the ventilation pipe 4, and the plurality of air outlets 5 are opposite to the plurality of vibrators 3. The ventilation pipe 4 is adapted to be connected with an air source, for example, the air source may be an air pump 6, and cooling air may be injected into the ventilation pipe 4 through the air pump 6, and finally the cooling air is guided to blow onto the vibrator 3 through the air outlet 5, so as to realize air cooling and heat dissipation of the vibrator 3.

[0021] In a preferred example, a refrigerator 7 and a dryer 8 are sequentially connected between the air pump 6 and the ventilation pipe 4. The refrigerator 7 can cool the cooling air to achieve a better heat dissipation effect on the vibrator 3; the dryer 8 can ensure the dryness of the cooling air, so that it is not easy to cause rust on the vibrator 3. For those skilled in the art, the refrigerator 7 and the dryer 8 are common and commercially available equipment, so they are not described in detail in the present invention.

[0022] like Figure 3 , Figure 4As shown, in some embodiments, the vibrator 3 is adapted to be rotatably connected to the plate body 2. For example, a mounting tube 10 is provided on the bottom surface of the mounting cavity 1, and a connecting column 11 is constructed at the bottom of the vibrator 3. A flange 12 is provided on the side wall of the connecting column 11, and a mounting ring groove 13 is provided on the inner wall of the mounting tube 10. During installation, the connecting column 11 is inserted into the mounting tube 10, and the flange 12 is clamped in the mounting ring groove 13, so that the vibrator 3 will only have circumferential rotational freedom and is not prone to axial movement. A driving mechanism 9 is also provided in the mounting cavity 1, and the driving mechanism 9 can drive the vibrator 3 to rotate, so that the air outlet 5 can be opposite to different circumferential surfaces of the vibrator 3.

[0023] It can be understood that for the vibration plate, the optimal layout is to install more vibrators 3 under its limited volume. The arrangement of the ventilation duct 4 will occupy part of the space of the installation cavity 1, so it is a better choice to arrange only one ventilation duct 4 on the side of the vibrator 3. However, this layout causes the cooling air blown out of the air outlet 5 to directly contact only one side surface of the vibrator 3, which will result in poor heat dissipation on the other side surface of the vibrator 3.

[0024] In the present invention, the vibrator 3 is driven to rotate by the driving mechanism 9. On the one hand, different circumferential surfaces of the vibrator 3 are opposite to the air outlet 5, so that the vibrator 3 can be blown by the cooling wind more evenly, and the heat dissipation of the vibrator 3 is higher. On the other hand, when the vibrator 3 rotates, the unevenness of the ultrasonic wave can be compensated to a certain extent, so that the ultrasonic performance of the vibration plate is better.

[0025] Due to design and manufacturing defects, the vibrator 3 may emit uneven ultrasonic waves, especially when the vibrator 3 is stationary, the amplitude may be concentrated in a specific part of the vibrator 3. However, when the vibrator 3 rotates, the amplitude distribution may be more uniform, because different parts will experience larger amplitudes during the rotation process. In addition, in a stationary state, ultrasonic waves usually propagate along the axial direction of the vibrator 3. However, when the vibrator 3 rotates, the propagation direction of the ultrasonic wave will change, which helps to distribute the ultrasonic wave more evenly in space.

[0026] For example, the driving mechanism 9 may include a motor (not shown), the output shaft of which is in driving connection with the vibrator 3. In a possible example, each vibrator 3 is individually connected to a micro motor, and the above-mentioned rotation of the vibrator 3 is achieved by the motor. Alternatively, a transmission belt (not shown) may be coupled to a plurality of vibrators 3, and the motor provides power to the transmission belt to drive the plurality of vibrators 3 to rotate simultaneously.

[0027] As another solution, a tooth structure 14 is constructed on the outer peripheral wall of the vibrator 3, and the driving mechanism 9 includes a driving shaft 15 slidably adapted in the air outlet 5, and an elastic reset member 16 is connected to the driving shaft 15. Specifically, an air outlet channel 18 is provided on the driving shaft 15, and a pressure valve 19 is provided in the air outlet channel 18. When cooling air is filled into the ventilation pipe 4, the driving shaft 15 will first be ejected to one side of the vibrator 3 under the action of wind pressure; and when the driving shaft 15 enters the extreme ejection stroke, the wind pressure will overcome the elastic valve member of the pressure valve 19 so that the cooling air is blown to the surface of the vibrator 3 through the air outlet channel 18.

[0028] More specifically, a rack 17 is provided on the drive shaft 15, and the rack 17 can mesh with the toothed structure 14. When the drive shaft 15 is ejected, the rack 17 can push the toothed structure 14 to drive the vibrator 3 to rotate, so that the cooling wind can blow on different surfaces of the vibrator 3 to dissipate heat.

[0029] In addition, the rack 17 is also adapted to be able to bounce laterally, and the wording "laterally" refers to the direction away from the vibrator 3. It can be imagined that when the drive shaft 15 is ejected, if the rack 17 moves laterally and disengages from the rack 17 structure, the drive shaft 15 will be retracted into the air outlet 5 under the elastic tension of the elastic reset member 16 to drive the vibrator 3 to rotate and blow heat for the next time. It can be understood that as the drive shaft 15 is continuously ejected and retracted, the vibrator 3 will continue to rotate in one direction, and the cooling wind blown out from the air outlet end of the air outlet channel 18 can cool the different circumferential surfaces of the vibrator 3.

[0030] In a preferred example, a flow-pushing channel 20 is provided on the side wall of the outlet end of the air outlet channel 18, and the flow-pushing channel 20 is opposite to the rack 17. When the drive shaft 15 enters the limit ejection stroke and the cooling air passes through the pressure valve 19, the airflow will be divided into two parts, one part is blown to the surface of the vibrator 3 for heat dissipation, and the other part is guided to the rack 17 through the flow-pushing channel 20, thereby pushing the rack 17 to separate from the toothed structure 14, and the drive shaft 15 enters the reset stroke. In this process, the stable pressurization state of the air pump 6 can be maintained, so that the cooling air can stably enter the air outlet channel 18.

[0031] In some embodiments, adjacent vibrators 3 are connected in series, which does not allow the vibrators 3 to rotate continuously in one direction. In this example, connecting tubes 21 are also provided on both sides of the drive shaft 15 in an axially elastic manner. A rack 17 is provided in each connecting tube 21. Among them, a spring extending in the axial direction may be provided between the connecting tube 21 and the drive shaft 15, and a spring extending in the lateral direction may be provided between the rack 17 and the connecting tube 21, that is, the connecting tube 21 and the rack 17 each achieve the expected elastic direction through a spring. Two electromagnets 22 are also provided on both sides of the drive shaft 15, and the two electromagnets 22 correspond to the two connecting tubes 21 respectively. When the electromagnet 22 is energized, the electromagnet 22 can adsorb the connecting tube 21, so that the connecting tube 21 and the drive shaft 15 maintain a fixed relative position.

[0032] In this example: 1. The drive shaft 15 is ejected under the action of wind pressure, for example, Figure 3 The electromagnet 22 corresponding to the rack 17 on the left side is in the energized state, and the other electromagnet 22 remains in the de-energized state. Subsequently, the rack 17 on the left side can push the vibrator 3 to rotate forward; 2. When the drive shaft 15 enters the ultimate ejection position, cooling air is ejected from the air outlet end of the air outlet channel 18, and cooling air is also ejected from the flow channel 20 to push the rack 17 on the left away from the toothed structure 14, and the drive shaft 15 is retracted under the action of the elastic reset member 16; 3. During this process, the right rack 17 is separated from the drive shaft 15, so the right rack 17 will not mesh with the toothed structure 14, so as not to affect the above-mentioned operation process; 4. Control the two electromagnets 22 to be energized alternately, and the vibrator 3 will be in a state of continuous forward and reverse rotation.

[0033] In a preferred case, the transmission ratio of the rack 17 and the toothed structure 14 can be selected so that the cooling wind can blow on two opposite surface positions of the vibrator 3, thereby obtaining a better cooling and heat dissipation effect.

[0034] 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.
