Description

Technical Field

[0001] This utility model relates to the field of hydrogen peroxide production technology, specifically to a mixing and proportioning device for hydrogen peroxide production. Background Technology

[0002] Hydrogen peroxide, also known as hydrogen peroxide solution, is an important oxidizing and bleaching agent with wide applications in various fields such as industry, medicine, and environmental protection. In industry, hydrogen peroxide is used for bleaching textiles and pulp in the paper industry. In the medical field, low-concentration hydrogen peroxide solutions can be used for wound disinfection. In the environmental field, hydrogen peroxide can be used in the oxidation process of wastewater treatment. Different application scenarios have strict requirements on the concentration of hydrogen peroxide. Through mixing and proportioning, high-concentration hydrogen peroxide can be diluted to the required concentration to meet various specific application needs.

[0003] In current hydrogen peroxide production mixing equipment, the stirring paddles inside the equipment are mostly in fixed positions when mixing high-purity hydrogen peroxide and water. This fixed position results in a fixed and predictable fluid flow pattern. Furthermore, the density difference between high-concentration hydrogen peroxide and water means that if the high-concentration hydrogen peroxide is not instantly and evenly dispersed after feeding, it will sink to the bottom of the tank due to gravity, creating a dead zone and reducing the mixing effect. Moreover, most current hydrogen peroxide production mixing equipment uses jacketed or coiled heat exchangers, requiring heat to be conducted from the material through a relatively static liquid layer to the inner wall of the equipment before it can be removed. Material near the inner wall is rapidly cooled, while the material in the center of the container experiences the highest temperature due to heat accumulation. This localized overheating causes the hydrogen peroxide in these areas to decompose at a faster rate, reducing the quality of the hydrogen peroxide production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a mixing device for hydrogen peroxide production includes a mixing tank 1. A control panel 2 is installed on the right side of the front of the mixing tank 1. Discharge pipes 3 are connected to the left and right sides below the front of the mixing tank 1. Mounting boxes 4 are fixed to the bottom of the left and right sides of the mixing tank 1, and the mounting boxes 4 are movably connected to the interior of the mounting boxes 4. A lifting frame 6 is provided above the mixing tank 1. A first motor 7 is fixed to the middle of the top of the lifting frame 6. The bottom end of the output shaft of the first motor 7 passes through to the bottom of the lifting frame 6 and is fixed to a rotating rod 8. A stirring paddle body 9 is fixed to the lower left and right sides of the surface of the rotating rod 8. A water tank 10 is fixed to the left and right sides of the top of the lifting frame 6, and the interior of the water tank 10 is filled with coolant. A circulation structure 11 is provided on the surface of the water tank 10. A proportioning structure 12 is fixed to the top of the front and rear sides of the mixing tank 1.

[0023] The adjustment structure 5 includes a second motor 51, a threaded rod 52, a first bevel gear 53, a second bevel gear 54, and a lifting sleeve 55. The second motor 51 is fixed below one side surface of the mounting box 4, and the output shaft of the second motor 51 extends through the interior of the mounting box 4. The threaded rod 52 is rotatably connected to the bottom of the inner wall of the mounting box 4. The first bevel gear 53 is fixed below the surface of the threaded rod 52. The second bevel gear 54 is fixed to one end of the output shaft of the second motor 51 and located inside the mounting box 4. The second bevel gear 54 meshes with the first bevel gear 53. The lifting sleeve 55 extends through the top of the mounting box 4 and is slidably connected to the mounting box 4. The top end of the threaded rod 52 extends into the interior of the lifting sleeve 55 and is threadedly connected to the inner wall of the lifting sleeve 55. The top of the lifting sleeve 55 is fixedly connected to the bottom of the lifting frame 6.

[0024] Limiting grooves 13 are provided on the upper part of the left and right sides of the inner wall of the mounting box 4, and limiting blocks 14 are fixed on the lower part of the left and right sides of the lifting sleeve 55. One side of the limiting block 14 extends into the interior of the limiting groove 13 and slides to connect with the inner wall of the limiting groove 13.

[0025] When the staff turns on the second motors 51 on both sides simultaneously through the control panel 2, the output shaft of the second motor 51 will drive the second bevel gear 54 to rotate, which in turn causes the first bevel gear 53 to drive the threaded rod 52 to rotate. Since the limit blocks 14 on the left and right sides slide inside the limit groove 13 to limit the lifting sleeve 55, the lifting sleeve 55 can only move up and down, which causes the lifting sleeve 55 to drive the upper lifting frame 6 to move up and down, adjust the mixing position up and down, and adjust the cooling heat exchange height.

[0026] The circulation structure 11 includes a water pump 111, a water distribution pipe 112, and a heat exchange pipe 113. The water pump 111 is fixed on the front and rear sides of the water tank 10, and the water pump 111 is connected to the water tank 10. The water distribution pipe 112 is connected above the water pump 111. The heat exchange pipe 113 is located below the lifting frame 6, and the heat exchange pipe 113 is U-shaped. The two ends of the heat exchange pipe 113 are connected to the water distribution pipes 112 on the front and rear sides, respectively.

[0027] There are several heat exchange tubes 113, which are evenly distributed on the surface of the water distribution pipe 112. The heat exchange tubes 113 are made of titanium alloy. When the front water pump 111 is turned on, the water pump 111 will draw the coolant inside the water tank 10 into the front water distribution pipe 112 and inject it into the heat exchange tubes 113. At this time, the rear water pump 111 is turned on, so that the coolant inside the heat exchange tubes 113 flows and flows into the rear water distribution pipe 112. It is then injected back into the water tank 10 by the rear water pump 111, forming a circulation. This process is used to exchange heat and cool down the high-concentration hydrogen peroxide and water inside the mixing tank 1. The heat exchange tubes 113 are made of titanium alloy, which can effectively resist the corrosion of high-concentration hydrogen peroxide and extend the service life of the heat exchange tubes 113.

[0028] The mixing structure 12 includes a support frame 121, a weighing sensor 122, a support platform 123, a storage tank 124, a feeding pipe 125, and a solenoid valve 126. The support frame 121 is fixed on the front and rear sides of the mixing tank 1. The weighing sensor 122 is fixed on the top of the support frame 121. The support platform 123 is fixed above the sensing head of the weighing sensor 122. The storage tank 124 is fixed on the top of the support platform 123. The feeding pipe 125 is connected to the lower part of one side surface of the storage tank 124, and one side of the feeding pipe 125 extends into the interior of the mixing tank 1. The solenoid valve 126 is installed on the surface of the feeding pipe 125.

[0029] High-concentration hydrogen peroxide and water that needs to be mixed and diluted are poured into the storage tanks 124 on the front and back sides respectively. The hydrogen peroxide and water in the upper storage tank 124 can be weighed by the weighing sensor 122. After the proportioning is completed, the staff can open the solenoid valves 126 on both sides of the red flag, so that the water or hydrogen peroxide in the storage tank 124 enters the mixing tank 1 through the injection pipe 125 for subsequent mixing treatment.

[0030] Working principle: When the equipment is started, the operator first sets the required production parameters through the control panel 2. The mixing structure 12 starts working, and the storage tanks 124 on the front and rear sides respectively hold high-concentration hydrogen peroxide and dilution water. The weighing sensor 122 monitors the weight change of the storage tanks 124 on the platform 123 in real time and feeds the data back to the control panel 2. When the preset ratio is reached, the control panel 2 issues a command, the solenoid valve 126 opens, and hydrogen peroxide and water are precisely injected into the mixing tank 1 through the injection pipe 125. Subsequently, the first motor 7 starts, driving the rotating rod 8 to drive the stirring paddle body 9 to rotate, performing preliminary stirring of the mixture. At the same time, the adjustment structure 5 starts operating, and the second motor 51 drives the second bevel gear 54 to rotate through the output shaft, meshing and driving the first bevel gear 53 and the threaded... As rod 52 rotates, the lifting sleeve 55 drives the lifting frame 6 to make vertical reciprocating motion under the sliding cooperation of the limiting block 14 and the limiting groove 13, so that the stirring paddle body 9 can perform mixing operations at different heights in the mixing tank 1, effectively avoiding mixing dead zones and stratification. The heat generated during the mixing process is handled by the circulation structure 11. The water pump 111 pumps the coolant in the water tank 10 into the water distribution pipe 112 and delivers it to the uniformly distributed titanium alloy heat exchange tubes 113. The coolant circulates in the U-shaped heat exchange tubes 113, achieving uniform cooling of the mixture through heat exchange. The titanium alloy material can effectively resist hydrogen peroxide corrosion. The up and down movement of the lifting frame 6 also drives the heat exchange tubes 113 to change position, further enhancing the heat exchange efficiency. Finally, the mixed hydrogen peroxide product is discharged through the discharge pipe 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
