Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mixing, and in particular to a medical-grade hydrogen peroxide production and preparation premixing device and method. BACKGROUND

[0002] Medical-grade hydrogen peroxide is an oxidizing solution formed by mixing high-concentration medical ozone with purified water. It is widely used in wound disinfection, inflammation treatment, and blood circulation improvement. The core of its preparation process is to achieve efficient and uniform mixing of ozone gas and water, and to ensure that the mixing process is safe, controllable, and pollution-free. Currently, common hydrogen peroxide preparation devices use Venturi jet structures to generate negative pressure in the converging section of the high-speed water flow, which sucks ozone from the suction port and completes the initial gas-liquid mixing in the mixing chamber.

[0003] However, the existing hydrogen peroxide premixing device has significant defects in actual application. Since medical water may contain trace impurities or micro-particles, and ozone is prone to produce by-products during dissolution in water, long-term operation can easily form fouling or blockage in the throat section (the smallest flow passage) of the jet, causing the water flow passage to narrow, the mixing efficiency to decrease, and even completely interrupting the mixing process, affecting the continuous and stable production of hydrogen peroxide. In addition, once the blockage occurs, the traditional device usually needs to be disassembled for manual cleaning, which is tedious and has a long maintenance cycle, not only reducing the efficiency of the device, but also increasing the risk of cross-contamination.

[0004] More importantly, standard and commercially available Venturi jet devices generally lack effective online cleaning or backwashing functions, and cannot remove the deposits in the throat section without disassembly, making it difficult to meet the use requirements of medical devices for high cleanliness, high reliability, and fast response. Some improved devices attempt to introduce flushing structures, but usually have problems such as uncontrollable flushing pressure, resulting in poor cleaning effect, or internal structure damage due to high-pressure flushing.

Detailed Implementation

[0039] The present invention will now be described in detail with reference to the accompanying drawings.

[0040] Example 1: A premixing device for producing medical-grade trioxide, such as... Figures 1-6 As shown, the system includes a tank 101, with a connecting pipe 102 flowing through the top of the tank 101. The connecting pipe 102 is made of food-grade stainless steel or polypropylene, with a mirror-polished inner wall to reduce fluid resistance and prevent microbial adhesion, suitable for medical-grade fluid transport. A suction port 103 is located on one side of the connecting pipe 102, which connects to the output of an external ozone generator via a flexible hose, for introducing high-concentration medical ozone into the mixing system. A jet pipe 104 is connected to the side of the connecting pipe 102 near the suction port 103. The jet pipe 104 gradually narrows from the inlet to the outlet, forming a tapered Venturi structure. Its throat section has the minimum flow cross-section, significantly increasing the water flow velocity and generating negative pressure. The connecting pipe 102 and the jet pipe 104 constitute a Venturi jet injector structure, automatically drawing in ozone gas using the low-pressure zone created by the high-speed water flow at the throat, achieving preliminary gas-liquid mixing without the need for an additional vacuum pump, resulting in energy efficiency.

[0041] The fixed block 105 is fixed to one side of the connecting pipe 102 outside near the outlet of the jet pipe 104, which is made of high-strength aluminum alloy or stainless steel and has good bending stiffness for supporting subsequent moving parts. The lifting flushing frame 106 is slidably connected to the fixed block 105, which is a U-shaped frame structure made of corrosion-resistant engineering plastic or stainless steel and can smoothly slide on the fixed block 105 in the axial direction. The backflushing groove 107 is opened in the lifting flushing frame 106, and the outlet thereof faces the outlet of the jet pipe 104. When backflushing, the high-pressure water changes direction after passing through the backflushing groove 107 and impacts the inside of the throat pipe section in the reverse direction, thereby removing scale or blockages and effectively solving the blockage problem of traditional jet devices caused by impurity deposition.

[0042] A pressure relief assembly and a valve assembly are also provided. The pressure relief assembly is arranged on the lifting flushing frame 106 and is used for dynamically adjusting the internal pressure during backflushing to prevent damage to the throat pipe section caused by excessive water pressure. The valve assembly is arranged on the connecting pipe 102 and the jet pipe 104 and is used for controlling the fluid on-off and residual liquid discharge, thereby improving the operation safety and maintenance convenience.

[0043] Specifically, the pressure relief assembly includes a pressure relief part 109 in a cylindrical piston structure, which is in sliding cooperation with the lifting flushing frame 106 and has a sealing ring on the cooperation surface to prevent leakage. The L-shaped pressure relief groove 108 is opened in the lifting flushing frame 106, one end of the pressure relief groove 108 communicates with the backflushing groove 107, and the other end extends upward to the installation position of the pressure relief part 109, so that part of the backflushing water can flow into the pressure relief groove 108. The pressure relief groove 108 communicates with the backflushing groove 107 to ensure that the pressure transmission path is unobstructed. The pressure relief part 109 is located in the pressure relief groove 108 and can move axially under the action of water pressure. The pressure relief part 109 is provided with a communication groove 1091, and the bottom of the communication groove 1091 communicates with the pressure relief groove 108 as a water inlet channel. The spring 1092 is fixed between the pressure relief part 109 and the lifting flushing frame 106, which is a spiral compression spring 1092 and presses the pressure relief part 109 tightly at the lower limit in the normal state to maintain the system seal. The upper part of the pressure relief part 109 is provided with a plurality of backflow ports 110 distributed in the circumferential direction, which are evenly distributed on the outer periphery of the pressure relief part 109 and are completely blocked by the inner wall of the lifting flushing frame 106 in the initial state, and are in the closed state. When the backflushing water pressure exceeds the set threshold value, the water flows into the communication groove 1091 through the pressure relief groove 108, pushes the pressure relief part 109 to move upward against the elastic force of the spring 1092, and drives the backflow ports 110 to gradually expose, thereby realizing automatic pressure relief. The higher the lifting, the larger the exposed area of the backflow ports 110, the more the backflow, and the stronger the pressure relief capacity, which has the self-adaptive adjustment characteristic. The lifting flushing frame 106 is close to the exhaust port 111, which is arranged above the movement path of the pressure relief part 109 and is used for exhausting air to avoid air resistance affecting the action response speed of the pressure relief part 109 and ensuring smooth and reliable movement thereof.

[0044] The backflow port 110 is designed as an inverted triangular shape, which can quickly increase the flow area under small displacement, improve the sensitivity of the low pressure area, and provide sufficient discharge capacity at high pressure, balancing the response speed and discharge efficiency, which is superior to rectangular or circular openings.

[0045] Specifically, the valve assembly includes a first valve 112 installed on the side of the jet pipe 104 close to the inlet, for controlling whether the high-pressure water enters the jet pipe 104; the valve is a manual or electric ball valve, which is quick to open and close and has good sealing performance, ensuring controllable mixing process. The first valve 112 controls the one-way flow of high-pressure water from the inlet to the outlet of the jet pipe 104, preventing backflow. The second valve 113 is installed on the bottom side of the connecting pipe 102 close to the jet pipe 104, and by opening the second valve 113, the residual fluid in the connecting pipe 102 can be discharged, preventing cross-contamination or bacterial growth. The third valve 1131 is installed in the middle of the jet pipe 104, which is used to discharge backwash sewage to avoid pollution of the main system. Among them, the second valve 113 and the third valve 1131 are preferably designed as ball valves, which have the advantages of full bore, low resistance, easy operation, corrosion resistance, etc., and are suitable for medical fluid control systems.

[0046] In addition, the lower part of the fixed block 105 is provided with a clamping part 114, which is a boss structure; the bottom of the lifting flushing frame 106 is provided with a clamping groove 115, which is a U-shaped or dovetail groove structure; when the lifting flushing frame 106 moves downward along the fixed block 105 to the limit position, the clamping groove 115 and the clamping part 114 are clamped with each other, forming a mechanical lock, enhancing the structural stability, preventing the flushing frame from bending or misplacing due to the reaction force of high-pressure water flow during backwashing, and improving the operation safety.

[0047] Example 2: based on example 1, as Figures 7-11As shown, the fixed ring 202 is fixed to the side of the fluidic pipe 104 close to the throat pipe section, serving as the base of the rotary transmission; the rotary ring 201 is rotatably connected outside the fixed ring 202, which can rotate freely around the fixed ring 202; the rotary ring 201 is provided with a protruding part 2011 on one side, used for receiving external thrust. The rubber block 203 is slidably connected to the side of the fluidic pipe 104 close to the throat pipe section along the left-right direction, which is made of silica gel or fluorine rubber, having good elasticity and sealing performance; the rubber block 203 is fixed with the fixed rods 204 symmetrically distributed along the rubber block 203, which are slidably connected with the fixed ring 202, forming a radial sliding pair; the rotary ring 201 is provided with a guide groove corresponding to the fixed rods 204, which is a diagonal or spiral groove, which can convert rotary motion into radial linear motion; the fixed rods 204 are inserted into the corresponding guide grooves, realizing motion transmission. The push rod 205 is fixed to the side of the lifting and flushing frame 106 close to the protruding part 2011, which moves downward and contacts the protruding part 2011; when the lifting and flushing frame 106 moves downward, the push rod 205 pushes the protruding part 2011, driving the rotary ring 201 to rotate, and then pushing the fixed rods 204 to slide to the right through the guide groove, finally driving the rubber block 203 to move to the right and press tightly on the side of the lifting and flushing frame 106 close to the outlet of the backwash groove 107, realizing dynamic sealing and preventing backwash water leakage.

[0048] Example 3: on the basis of example 2, as shown in Figure 12 As shown, the connecting ring 301 is fixed to the side of the connecting pipe 102 close to the fluidic pipe 104, used for enhancing the structural connection strength; the connecting ring 301 is sleeved outside the fluidic pipe 104, forming concentric support; the connecting ring 301 is fixed with the guide vanes 302 arranged in a ring shape, which are arranged in an inclined or spiral shape; when the ozone is sucked into the connecting pipe 102 through the suction port 103, due to the blocking effect of the fluidic pipe 104, most of the ozone will be locally accumulated near the suction port 103; the airflow is guided to rotate in the circumferential direction through the guide vanes 302, breaking the laminar flow state, promoting the turbulent mixing of ozone and high-speed water flow, improving the gas-liquid contact area and mixing uniformity, reducing the escape of unreacted ozone, and improving the dissolution efficiency.

[0049] The specific working principle of the premixing operation of the production of trihydrogen water is as follows: first, open the first valve 112, close the second valve 113 and the third valve 1131, high-pressure water enters from the left inlet of the jet pipe 104, the flow channel gradually narrows (contracts), when the water enters the throat pipe section (the smallest cross section, also known as the reduced diameter section), the speed reaches the maximum, according to Bernoulli's principle, the static pressure decreases significantly, and a low-pressure area (negative pressure / vacuum) is formed in the connecting pipe 102 near the throat pipe. Through the suction port 103, ozone is sucked into the connecting pipe 102. The high-speed water and ozone collide, shear and diffuse in the mixing section, realizing momentum exchange and uniform mixing. The mixed fluid enters the diffusion section (the pipe gradually widens), the flow rate gradually decreases, the kinetic energy is converted into static pressure energy, and the outlet pressure is higher than the pressure of the suction port 103, which can deliver the mixed fluid to the tank 101 of the downstream system. When the throat pipe section is blocked, the first valve 112 is closed to cut off the water source, the second valve 113 is opened, and the lifting flushing frame 106 is pushed down along the fixed block 105 so that the backflushing groove 107 is aligned with the throat pipe section. The high-pressure water entering the lifting flushing frame 106 is reversed and flushed into the jet pipe 104 from the left through the backflushing groove 107, so as to solve the problem of easy blockage of the throat pipe section. The backflushed sewage is discharged through the second valve 113.

[0050] In the above backflushing process, if the backflushing water pressure is too high, it needs to be appropriately relieved, otherwise the water pressure will act on the throat pipe section with high intensity, causing damage to the throat pipe section. The specific dynamic pressure relief adjustment operation is as follows: when the backflushing water pressure exceeds a certain threshold value, the water in the backflushing groove 107 will partially flow upward into the pressure relief groove 108, then enter the communication groove 1091, and under the action of water pressure, the pressure relief part 109 moves upward, the spring 1092 is compressed, and the backflow port 110 on the pressure relief part 109 is exposed upward, the water in the communication groove 1091 flows back through the backflow port 110, and the higher the pressure relief part 109 is lifted, the larger the area of the backflow port 110 exposed upward, so the more water flows back, realizing self-adaptive pressure regulation and protecting the key components.

[0051] In the above backflushing process, in order to more stably backflush, when the lifting flushing frame 106 is pushed down, the clamping groove 115 on the lifting flushing frame 106 is clamped into the clamping part 114 of the fixed block 105, reinforcing the lower part of the lifting flushing frame 106, preventing the reaction force of the backflushing water from bending the lower part of the lifting flushing frame 106, and ensuring the structural stability of the flushing process.

[0052] When the lifting and flushing frame 106 moves downward, the push rod 205 on it moves downward synchronously. When the push rod 205 moves downward to contact the convex part 2011 of the rotating ring 201, the push rod 205 pushes the convex part 2011, so that the rotating ring 201 rotates. The rotating ring 201 pushes the fixed rod 204 along the fixed ring 202 to the right through the guide groove on it, so as to drive the rubber block 203 to move to the right and press tightly on the side of the lower part of the lifting and flushing frame 106 close to the outlet of the back flushing groove 107, so as to achieve the sealing effect, prevent water leakage, and improve the back flushing efficiency.

[0053] When the ozone is sucked into the connecting pipe 102 through the suction port 103, due to the blocking effect of the jet pipe 104, most of the ozone is locally accumulated in the connecting pipe 102 close to the suction port 103. By arranging the guide vane 302, a part of the ozone can rotate along the guide vane 302, so as to uniformly disperse the ozone, improve the mixing effect of the ozone and water, reduce the phenomenon of too high or too low local concentration, and improve the consistency of the quality of the ozone water.

[0054] The above embodiments are only preferred embodiments of the present application, and are not used to limit the scope of the present application. Therefore, equivalent changes made according to the contents of the claims of the present application should be included in the scope of the claims of the present application.
