Description

Technical Field

[0001] This utility model belongs to the field of diaphragm production technology, and in particular relates to a raw material mixing device for the production of alkaline water electrolysis diaphragms. Background Technology

[0002] The diaphragm in alkaline water electrolysis is a core component of the electrolyzer in alkaline water electrolysis hydrogen production equipment. Its main function is to allow efficient conduction of hydroxide ions to maintain the electrolysis reaction, while strictly preventing the mixing of hydrogen and oxygen (to prevent the risk of explosion), and it must withstand long-term corrosion from high-concentration alkaline solutions and pressure fluctuations. The mainstream diaphragm uses polyphenylene sulfide (PPS)-based composite materials, prepared by uniformly mixing polymer resins, hydrophilic inorganic particles, organic solvents, and additives. Its performance directly determines the electrolysis efficiency and equipment lifespan, making it a key material for the large-scale application of alkaline water electrolysis hydrogen production technology.

[0003] As a core component of the electrolyzer, the performance of alkaline water electrolysis membrane is highly dependent on the uniformity of raw material mixing. Uneven mixing can easily lead to the agglomeration of inorganic particles (particle size exceeding 1μm) and the separation of polymers from the solvent phase, affecting the uniformity of subsequent coating. Furthermore, the high viscosity of the raw materials can easily leave residues on the inner wall of the mixing device, resulting in waste of raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device for the production of alkaline water electrolysis diaphragms. In order to solve the following problems that occur during the raw material mixing process: the influence of raw material mixing uniformity on diaphragm performance, uneven mixing easily causes inorganic particle agglomeration (particle size exceeding 1μm) and separation of polymer and solvent phases, which in turn affects the uniformity of subsequent coating.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses a servo motor to drive the second and first bevel gears to rotate, thereby enabling the inner and outer cylinders to be in a specific initial venting state. This allows nitrogen from the nitrogen supply equipment to enter the inner cylinder and push the annular piston against the support plate, causing the support rod of the first stirring assembly to move closer together and the rubber strip on the vertical stirring blades to adhere to the inner wall of the heating mixing tank. Subsequently, the servo motor rotates in the opposite direction to reset and change the venting state. Raw materials are then added to the heating mixing tank, and nitrogen is introduced to create an inert environment. This prevents oxidation reactions, reduces contact between the solution and air, prevents the generation of bubbles and impurities, improves the uniformity of the solution, and prepares for subsequent stirring while ensuring full utilization and uniform mixing of raw materials.

[0014] 2. This utility model starts the motor at the bottom of the heating mixing tank to drive the stirring shaft to rotate, so that the first stirring component, the second stirring component and the horizontal stirring blade rotate to stir. When the servo motor does not rotate, the second bevel gear connected to its output end and the first bevel gear fixedly connected to the inner cylinder cooperate with each other to lock the inner cylinder 15, so as to maintain the specific vent hole cooperation state. By intermittently pressurizing and depressurizing the air pressure chamber, the inclined stirring blade is frequently reciprocated in the inclined direction, so as to further mix the various raw materials evenly and improve the mixing reaction effect.

[0015] 3. This utility model opens the discharge valve after mixing, while allowing the vertical and horizontal stirring blades to continue rotating, and opens the air inlet valve to introduce nitrogen gas, thereby accelerating the falling and discharge of the casting liquid from the inner wall and bottom of the heating mixing tank, reducing casting liquid residue and raw material loss, and reducing the difficulty of subsequent cleaning of the heating mixing tank.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] In this embodiment of the present invention, such as Figure 1 and Figure 2 As shown: the inner cylinder 15 is rotatably connected and coaxially nested inside the outer cylinder 14. The top of the heating mixing tank 1 is fixedly installed with a top cover 11. A linkage disk 27 is rotatably set at the center of the top cover 11. A shaft hole 19 is opened at the center of the linkage disk 27. The top of the outer cylinder 14 is fixedly set at the bottom of the linkage disk 27. The top of the inner cylinder 15 passes through the linkage disk 27 and the two are rotatably connected. A first bevel gear 24 is fixed at the upper end of the inner cylinder 15. A servo motor 12 is installed at the top of the linkage disk 27. A second bevel gear 25 is fixedly connected to the output end of the servo motor 12.

A fourth vent hole 23 that matches the second vent hole 21 is opened at the bottom of the inner cylinder 15.

[0032] In this embodiment of the present invention, such as Figure 1 and Figure 2As shown: A gas supply pipe 26 extending into the inner cavity of the inner cylinder 15 is provided on one side of the heating mixing tank 1, and the front end of the gas supply pipe 26 is rotatably connected to the inner cylinder 15; a nitrogen supply device 28 is installed on the side of the heating mixing tank 1 near the gas supply pipe 26; a discharge pipe is installed near the bottom of the heating mixing tank 1, and a discharge valve 40 is installed on the discharge pipe; the gas outlet of the nitrogen supply device 28 is connected to the gas supply pipe 26; a support frame 13 for supporting the heating mixing tank 1 is provided at the bottom of the heating mixing tank 1; several horizontal stirring blades 9 are installed at equal intervals at the lower end of the stirring shaft 3; the nitrogen supply device 28 can provide nitrogen, and the main function of nitrogen is as an inert protective gas to prevent the raw materials from oxidizing during the mixing process.

[0033] In this embodiment of the present invention, such as Figure 2 As shown: The first stirring assembly 5 includes a vertical stirring blade 29 and a support rod 30. The side of the vertical stirring blade 29 closest to the stirring shaft 3 is hinged to one end of two vertically distributed support rods 30. The support plate 7 and the stirring shaft 3 are respectively hinged to the corresponding support rods 30. A rubber strip 31 is installed on the side of the vertical stirring blade 29 away from the stirring shaft 3. When the support plate 7 moves downward, the two support rods 30 of the first stirring assembly 5 will move towards the middle until the rubber strip 31 on the vertical stirring blade 29 adheres to the inner wall of the heating mixing tank 1.

[0034] In this embodiment of the present invention, such as Figure 4 and Figure 5 As shown: The second stirring assembly 6 includes an inclined stirring blade 32 and a square tube 33. A cylindrical piston 34 is fixedly connected to one side of the inclined stirring blade 32. The square tube 33 is fixedly connected to the stirring shaft 3. The cylindrical piston 34 is slidably sleeved on the outside of the square tube 33. The square tube 33 is connected to the air pressure chamber 10 inside the stirring shaft 3. The square slots at the bottom of the square tube 33 and the cylindrical piston 34 can limit their rotation. After nitrogen enters the air pressure chamber 10, it is dispersed into the interior of each square tube 33. The nitrogen entering the square tube 33 pushes the inclined stirring blade 32 to move obliquely upward.

[0035] In this embodiment of the present invention, such as Figure 1 As shown: The top of the top cover 11 is fixedly equipped with a liquid inlet pipe 35, a feed hopper 36 and an air inlet pipe 38. The liquid inlet pipe 35, the feed hopper 36 and the air inlet pipe 38 are all connected to the inner cavity of the heating mixing tank 1. A liquid inlet valve 37 is installed on the liquid inlet pipe 35 and an air inlet valve 39 is installed on the air inlet pipe 38. The upper end of the air inlet pipe 38 is connected to the air inlet pipe 26.

[0036] The working principle of this embodiment is as follows: During operation, the servo motor 12 is first started. The second bevel gear 25 on the output end of the servo motor 12 drives the first bevel gear 24 to rotate, which in turn drives the inner cylinder 15 in the adjusting assembly 4 to rotate. This causes the first vent 20 to communicate with the third vent 22, while the second vent 21 and the fourth vent 23 are misaligned and not connected. This is the initial state. The nitrogen supply device 28 is then started to output nitrogen gas, which is input into the inner cylinder 15 and enters the annular piston chamber 16 through the first vent 20 and the second vent 21. This pushes the annular piston 17 to move downward, while simultaneously driving the support plate 7 to move downward. One end of each of the two support rods 30 is hinged to the support plate 7 and the stirring shaft 3, respectively. Therefore, the two support rods 30 of the first stirring assembly 5 move towards the center. The mixture is stirred until the rubber strip 31 on the vertical stirring blade 29 adheres to the inner wall of the heating mixing tank 1. Then, the servo motor 12 drives the second bevel gear 25 and the first bevel gear 24 to rotate in opposite directions to complete the reset. At this time, the first vent 20 and the third vent 22 are misaligned, and the second vent 21 and the fourth vent 23 are connected. Then, the feed hopper 36 and the liquid delivery valve 37 on the liquid delivery pipe 35 are opened to add raw materials into the heating mixing tank 1. At the same time, the air inlet valve 39 on the air inlet pipe 38 is opened, and nitrogen gas enters the heating mixing tank 1 through the air inlet pipe 38 to create an inert environment inside the heating mixing tank 1. After the addition is completed, the feed hopper 36, the liquid delivery valve 37 and the air inlet valve 39 are closed. At the same time, the heating mixing tank 1 begins to heat to a suitable temperature. Then, the electric motor at the bottom of the heating mixing tank 1 is started. Machine 2, motor 2 drives stirring shaft 3 to rotate, thereby driving the first stirring assembly 5, the second stirring assembly 6 and the horizontal stirring blade 9 to rotate. The top of the outer cylinder 14 is fixedly set at the bottom of the linkage disk 27, and the top of the inner cylinder 15 passes through the linkage disk 27 and the two are rotatably connected, so the linkage disk 27 also rotates. When the servo motor 12 does not rotate, the inner cylinder 15 can be locked by the mutual cooperation between the second bevel gear 25 connected to its output end and the first bevel gear 24 fixedly connected to the inner cylinder 15, so as to ensure that the position of the inner cylinder 15 is fixed to maintain the misalignment of the first vent 20 and the third vent 22, and the communication between the second vent 21 and the fourth vent 23. After nitrogen enters the gas pressure chamber 10, it is dispersed into each square tube 33 and enters the square tube 33. The nitrogen pressure in the part drives the inclined stirring blade 32 to move obliquely upward. After the nitrogen supply device 28 controls the pressure chamber 10 to depressurize, the inclined stirring blade 32 falls back due to its own gravity. In this way, the raw materials are mixed obliquely upward during the stirring process to improve the mixing reaction effect. By intermittently pressurizing and depressurizing the inside of the pressure chamber 10, the inclined stirring blade 32 can be frequently reciprocated in oblique upward. After the mixing is completed after the predetermined time, the discharge valve 40 is opened, and the mixed casting liquid can be discharged from the discharge pipe. At the same time, the vertical stirring blade 29 and the horizontal stirring blade 9 continue to rotate, which can accelerate the falling and discharge of the casting liquid from the inner wall and bottom of the heating mixing tank 1. At the same time, the air inlet valve 39 can be opened, and the nitrogen gas introduced by the air inlet pipe 38 can also help the casting liquid to be discharged from the discharge pipe.
