[0019] Compared with the prior art, the beneficial effects of the invention are as follows:

[0020] 1. This technology utilizes ultrasonic oxidation leaching and iron removal technology, abandoning the traditional oxidation precipitation method using sodium chlorate or hydrogen peroxide. When ultrasonic waves of a certain intensity pass through the solution, a series of high-pressure and high-temperature kinetic processes will occur at the moment when the active oxygen micro-nano bubbles or cavitation bubbles generated in the solution collapse and burst. The movement of the active oxygen micro-nano bubbles is triggered by the energy of the bubbles themselves.

Compared with the traditional iron removal technology, the operation cost is greatly reduced, and the safety and environmental protection problems brought by dangerous chemicals are solved.

[0021] 2. The equipment is simple, easy to operate, economical and practical, safe and environmentally friendly. The equipment runs stably and reliably, and the comprehensive economic benefits are remarkable. It solves the problems of volume balance in the iron removal (leaching) process of hydrogen peroxide and sodium chlorate and the introduction of Na+ and Cl- into the system. At the same time, it solves the safety and environmental protection problems brought by dangerous chemicals; the oxidation speed is fast, the oxygen utilization rate is high, and the primary leaching rate is over 95%; the iron slag has good filtration performance and is easy to wash, and the iron slag can be comprehensively utilized as resources.

[0022] 3. By using the super-spray emitter, ultrasonic connecting rod and air inlet pipe in cooperation, vibrations are generated and the vibrating rod at the top end of the upper part of the filter net works, so that the vibrating rod can form a synchronous vibration with the ultrasonic connecting rod to meet the unified reaction at various positions inside the cylinder body, avoiding the inefficient mixing of raw materials at the lower position of the cylinder body. And since the inner cylinder does not directly contact the cylinder body, the inner cylinder can also vibrate, greatly avoiding the adhesion of raw materials to the inner wall of the inner cylinder and greatly improving the mixing reaction efficiency.

[0023] 4. Through the hemispherical protective cover, the force generated by oxygen and the ultrasonic connecting rod can be output directionally. And due to the hemispherical structure of the hemispherical protective cover, it can be used as a sound wave amplifier to enhance the vibration and ultrasonic intensity. The installed hemispherical mesh cover can avoid affecting the work of the ultrasonic connecting rod and protect it, making the device use continuously and stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the invention.

[0034] The invention provides: an ultrasonic oxygen-enriched reactor, such as Figures 1 - 8As shown in the figure, it includes a cylinder body 1. The interior of the cylinder body 1 is divided into an ultrasonic reaction zone 2 and a gas-liquid mixing reaction zone 3. An inner cylinder 7 is fitted and installed inside the cylinder body 1 at the position of the ultrasonic reaction zone 2. A filter screen 16 is placed inside the cylinder body 1 at the position of the gas-liquid mixing reaction zone 3. Several groups of vibrating rods 17 are installed above the filter screen 16. An upper head 18 is movably installed on the upper part of the cylinder body 1. A limiting pipe 32 is hermetically inserted and installed at the bottom of the upper head 18. A spray plate 33 is installed inside the limiting pipe 32. Several groups of ejectors 36 are installed through the spray plate 33. A liquid inlet pipe 23 is installed through the center of the upper head 18. A super spray emitter 24 is installed at the bottom of the liquid inlet pipe 23. Two groups of air inlet pipes 27 are symmetrically installed on both sides of the upper head 18. A group of ultrasonic connection rods 30 are installed inside each group of air inlet pipes 27.

[0035] Preferably, a middle manhole 4 is installed through the outer arc surface of the cylinder body 1. A pressure gauge interface 5 is installed through the middle manhole 4. A sight glass 6 is installed through the middle manhole 4 below the pressure gauge interface 5. The middle manhole 4 installed through the outside of the cylinder body 1 ensures the overall sealing of the cylinder body 1 when the pressure gauge interface 5 and the sight glass 6 are installed and used. It is connected to an external pressure gauge through the pressure gauge interface 5 to continuously measure the internal pressure of the cylinder body 1, adjust the intensity of the liquid and gas injected into the cylinder body 1, and ensure that the staff can quickly observe the internal reaction situation of the cylinder body 1 through the opened sight glass 6, making the overall use inside the cylinder body 1 safer and avoiding incomplete reactions caused by excessive internal pressure in the cylinder body 1.

[0036] Furthermore, two groups of inclined plates 8 are symmetrically arranged up and down on the inner cylinder 7. Each group of inclined plates 8 is in contact with the inner wall of the cylinder body 1. A first sealing protection sleeve 9 is installed through the inner cylinder 7 corresponding to the position of the pressure gauge interface 5. The inclined plates 8 installed at both ends of the inner cylinder 7 form a space between the inner cylinder 7 and the cylinder body 1 after the inner cylinder 7 is installed inside the cylinder body 1, which improves the service strength of the cylinder body 1. At the same time, it can ensure that after the ultrasonic connection rod 30 is connected to external equipment for work, the inner cylinder 7 can vibrate in cooperation with the ultrasonic connection rod 30 to complete the cooperation with the ultrasonic connection rod 30 from inside the cylinder body 1, realizing the efficient processing of the raw materials inside the cylinder body 1. At the same time, the first sealing protection sleeve 9 installed through the inclined plates 8 cooperates with the detection end of the pressure gauge interface 5 to complete the protection of the pressure gauge interface 5, and can also improve the sealing performance of the inner cylinder 7 to the greatest extent and reduce leakage. At the same time, an observation window is provided on the inner cylinder 7 corresponding to the position of the middle manhole 4, which can cooperate with the sight glass 6 to enable the staff to better observe the internal situation.

[0037] Furthermore, a limiting ring 10 is installed inside the gas-liquid mixing reaction zone 3. A liquid leakage port 11 is opened at the center of the inner arc surface of the gas-liquid mixing reaction zone 3. A shielding cover 12 is snap-fitted and installed inside the liquid leakage port 11. The filter screen 16 is placed in contact with the surface of the limiting ring 10. Inside the gas-liquid mixing reaction zone 3, there is a vibrating rod 17 for assisting the use of the ultrasonic connecting rod 30 and a filter screen 16 for assisting gas-liquid contact. When the solution enters the ultrasonic reaction zone 2 from top to bottom, under the vibration of ultrasonic waves and the push of ultrasonic gas volume, the solution forms a mist and continuously collides with oxygen atomic groups, rapidly reacts, and generates tens of thousands of tiny bubbles, namely cavitation bubbles. These bubbles grow in the negative pressure zone formed by the longitudinal propagation of ultrasonic waves and rapidly collapse in the positive pressure zone, so they are compressed and stretched under alternating positive and negative pressures. Oxygen continuously reacts with metal ions in the solution, and then enters the high-speed rotating negative pressure convection zone. Under the high-speed rotating negative pressure, the solution generates micro-nano bubbles, increasing the contact area and enabling the reaction to proceed rapidly. After entering the stock solution reaction tank, the micro-nano bubbles are continuously mixed with the solution for reaction until the reaction ends. The limiting ring 10 provided inside the gas-liquid mixing reaction zone 3 positions the filter screen 16 to ensure the installation position of the filter screen 16. The vibrating rod 17 installed above the filter screen 16 is used in cooperation with the ultrasonic connecting rod 30. The liquid leakage port 11 opened inside the gas-liquid mixing reaction zone 3 positions the shielding cover 12, and the shielding cover 12 is used to prevent incompletely reacted impurities from being discharged through the drain pipe 15, improving the usage efficiency of the device.

[0038] It should be noted that several groups of legs 13 are installed at equal arcs at the bottom of the cylinder body 1. A manhole 14 is installed at the position corresponding to the liquid leakage port 11 at the bottom of the cylinder body 1. A drain pipe 15 is installed through the bottom of the manhole 14. The drain pipe 15 is correspondingly inserted into the liquid leakage port 11. The legs 13 installed at the bottom of the cylinder body 1 lift the cylinder body 1, enabling the drain pipe 15 at the bottom of the cylinder body 1 to stably discharge liquid. At the same time, the installed legs 13 can also ensure the stability of the use of the cylinder body 1. The installed manhole 14 can ensure the sealing of the drain pipe 15 and prevent liquid leakage.

[0039] Specifically, a manhole 19 is installed at the center of the upper head 18. Two groups of connecting pipes 20 are symmetrically installed through the upper head 18 on both sides of the manhole 19. A second sealing protection sleeve 21 is installed through the center of the manhole 19. The manhole 19 installed at the center of the upper head 18 positions the sealing cover 22, enabling the liquid inlet pipe 23 installed at the center of the sealing cover 22 to stably extend into the upper head 18 for use. And because the second sealing protection sleeve 21 installed through the center of the manhole 19 makes the liquid inlet pipe 23 more firm after extending into the upper head 18 and improves its installation sealing performance at the same time. The connecting pipes 20 position the cover 26 to ensure the installation and use position of the ultrasonic connecting rod 30 is fixed, ensuring that the device can stably output ultrasonic waves and oxygen to complete the treatment of the materials entering the cylinder body 1.

[0040] In addition, a sealing cover 22 is fitted on the upper surface of the manhole 19. Four groups of hanging heads 38 are symmetrically installed on the outer surface of the sealing cover 22. The liquid inlet pipe 23 is installed through the center of the sealing cover 22. The bottom end of the liquid inlet pipe 23 extends out from inside the second sealing protection sleeve 21. The ultra-spray emitter 24 is located inside the upper head 18. A group of exhaust pipes 25 are installed through the sealing cover 22 on one side of the liquid inlet pipe 23. The hanging heads 38 installed on the upper surface of the upper head 18 enable the upper head 18 to be stably pulled out from the top end of the cylinder 1, allowing the staff to better clean and repair the internal structure of the cylinder 1, further ensuring the safety of the device during use. The ultra-spray emitter 24 installed at the output end of the liquid inlet pipe 23 can quickly atomize and spray the liquid, causing the solution to form a mist and continuously collide and react rapidly with the oxygen atomic groups, and generating tens of thousands of tiny bubbles to complete the subsequent reaction. The installed exhaust pipe 25 can prevent the internal pressure of the cylinder 1 from being too high. When connecting the pressure gauge interface 5 to an external pressure gauge to detect the internal pressure data of the cylinder 1, the switch of the exhaust pipe 25 can be controlled in real time to handle the internal pressure problem of the cylinder 1.

[0041] As for this, each group of connecting pipes 20 is sealed with a cover 26 at the top end. A group of air inlet pipes 27 are installed through the center of each group of covers 26. A group of hemispherical protective covers 28 are installed at the low end of each group of air inlet pipes 27 in a communicating manner. A group of hemispherical mesh covers 29 are installed at the bottom end of each group of hemispherical protective covers 28 in a clamping manner. The air inlet pipe 27 installed at the center of the cover 26 is not only used to convey oxygen into the cylinder 1, but also can limit the position of the ultrasonic connecting rod 30, enabling the oxygen to quickly react with the solution through the operation of the ultrasonic connecting rod 30 after being sent into the cylinder 1. The hemispherical protective cover 28 provided at the bottom end of the air inlet pipe 27 limits the output direction of the oxygen, while the hemispherical mesh cover 29 clamped at the bottom end of the hemispherical protective cover 28 protects the mechanical energy of the ultrasonic connecting rod 30. It can not only ensure the delivery of oxygen, but also ensure that larger impurities in the solution will not contact the ultrasonic connecting rod 30 during the reaction process, which will affect the use of the ultrasonic connecting rod 30, and further improve the service life of the ultrasonic connecting rod 30.

[0042] Furthermore, a group of ultrasonic connecting rods 30 are installed at the center of each group of air inlet pipes 27. A group of limit clips 31 are installed in a clamping manner on the outside of each group of air inlet pipes 27. The clamping end of the limit clip 31 extends into the air inlet pipe 27 to clamp the ultrasonic connecting rod 30. The clamping end of the limit clip 31 is installed through the air inlet pipe 27. At the same time, the clamping end can stably clamp the ultrasonic connecting rod 30 to limit the use position of the ultrasonic connecting rod 30, enabling the ultrasonic connecting rod 30 to be stably connected to the external structure, realizing the generation of ultrasonic waves, and ensuring the efficient reaction with the solution.

[0043] Furthermore, a connecting plug plate 34 is fixedly installed at the top end of the injection plate 33. The connecting plug plate 34 is butted and inserted into the interior of the upper head 18. A water accumulation prevention plate 35 is fixedly installed at the center of the upper surface of the injection plate 33. The injectors 36 are located on both sides of the water accumulation prevention plate 35. A sealing insertion pipe 37 is fixedly installed at the bottom of the injection plate 33. The sealing insertion pipe 37 is closely inserted into the interior of the cylinder body 1 for sealing connection. The connecting plug plate 34 installed at the top end of the injection plate 33 is used to ensure the connection between the upper head 18 and the limiting pipe 32, so that the injection plate 33 and the upper head 18 form an integral unit for use. The water accumulation prevention plate 35 installed on the upper surface of the injection plate 33 is used to prevent the solution from accumulating after being fed into the interior of the upper head 18. The solution is fed into the interior of the injector 36 through the water accumulation prevention plate 35 to complete the injection. The sealing insertion pipe 37 at the bottom of the injection plate 33 can ensure the connection between the upper head 18 and the cylinder body 1, improving the sealing performance and connection performance between the upper head 18 and the cylinder body 1.
