Abstract

The application discloses an aluminum alloy surface treatment additive synthesis stirring tank and relates to the technical field of metal surface treatment additive production equipment. The aluminum alloy surface treatment additive synthesis stirring tank comprises a heating tank. When the aluminum alloy surface treatment additive synthesis stirring tank is used, solid powders such as metal salts are poured into the tank. Since the powders are small in particle size and light in weight, the powders are likely to cause dust to be raised when the powders are poured into the tank. The raised dust leads to waste of raw materials and even easy inhalation of the dust by operators, thereby endangering the health of the operators. The problem that the solid powders are likely to cause dust to be raised and splashed, waste of raw materials and harm to the health of operators when the solid powders are put in is solved by setting a storage box, a baffle, an elastic spring, an inclined block and a feeding pipe. After the powders are loaded into the storage box, the baffle is lifted upward, the elastic spring drives the inclined block to extend and clamp the baffle, the powders fall into the heating tank after entering the feeding pipe through the discharge port of the storage box, and the problem is solved.

Description

Technical Field

[0001] This invention relates to the technical field of metal surface treatment additive production equipment, specifically a stirring tank for synthesizing aluminum alloy surface treatment additives. Background Technology

[0002] Aluminum alloy surface treatment additives are key agents for improving the corrosion resistance and wear resistance of workpieces, and are widely used in aerospace, automotive manufacturing, and other fields. Their synthesis process requires adding various metal salt solid powders to a liquid base in a specific ratio, followed by thorough mixing and heating in a stirred tank to obtain a stable finished product. In this process, the stirred tank plays a crucial role in solid-liquid dispersion and heat transfer; its operating status directly affects reaction efficiency and product quality, making it an indispensable core piece of equipment in the additive production line.

[0003] In the process of using existing mixing tanks for synthesizing aluminum alloy surface treatment additives, when adding solid powders such as metal salts into the heating tank, the powders are poured in from the top of the heating tank. Because the powder particles are small and light, dust is stirred up when the powders are poured in. This dust leads to waste of raw materials and may even cause operators to inhale the dust, which may harm their health. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mixing tank for synthesizing aluminum alloy surface treatment additives, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stirring tank for synthesizing aluminum alloy surface treatment additives, comprising a heating tank, an inlet pipe fixed to the outer wall of the heating tank, the inlet pipe penetrating the outer wall of the heating tank and fixedly connected at the penetration point, a drive motor fixed to the bottom of the heating tank, the output end of the drive motor penetrating the bottom of the heating tank and rotatably connected at the penetration point, an outlet pipe fixed to the bottom of the heating tank, the outlet pipe penetrating the bottom of the heating tank and fixedly connected at the penetration point, a one-way valve fixed to the outer wall of the outlet pipe, a stirring rod fixed to the output end of the drive motor, a control panel fixed to the outer wall of the heating tank, and a bracket fixed to the top of the heating tank, the bracket being used to provide installation support for the storage box; A storage box is fixed to the outer wall of the support. The top of the storage box has a feed inlet, through which solid powders such as metal salts can be poured into the storage box. The bottom of the storage box has a discharge outlet, through which solid powders such as metal salts can be discharged from the storage box. A baffle slides on the inner wall of the storage box and is used to block the discharge port of the storage box. The outer wall of the baffle has a slot for providing installation space for a spring and a ramp. A spring is fixed inside the slot of the baffle, and a ramp is fixed to the end of the spring. The ramp slides on the inner wall of the slot and is used to fix the baffle. The feed pipe is fixed to the top of the heating tank and located below the outlet of the storage box. The feed pipe passes through the top of the heating tank and is fixedly connected at the penetration point. The feed pipe is used to transport the solid powder inside the storage box into the heating tank to prevent dust leakage.

[0006] According to the above technical solution, a rotating rod is fixed at the top of the stirring rod, and the rotating rod can rotate synchronously with the stirring rod to transmit power.

[0007] According to the above technical solution, a rotating rod is fixed to the outer wall of the rotating rod. The rotating rod is provided in multiple sets. The rotating rod is used to unclog the feed pipe, disperse the powder in the feed pipe, and prevent the material from being blocked.

[0008] According to the above technical solution, the heating tank is equipped with a dispersing device inside, which is used to evenly sprinkle solid powder such as metal salt into the heating tank. The heating tank is also equipped with an anti-piling device inside, which is used to prevent the solid powder such as metal salt inside the storage box from getting damp and piling up.

[0009] According to the above technical solution, the scattering device includes: a scattering disc, which is fixed at the bottom of the feed pipe and is used to receive the falling material; The scattering port is located at the bottom of the scattering tray and is used to discharge solid powders such as metal salts that fall onto the scattering tray.

[0010] According to the above technical solution, the stirring rod is fixed to the outer wall of the rotating rod and is used to stir the solid powder scattered on the dispensing plate to achieve uniform material spreading.

[0011] According to the above technical solution, the anti-piling device includes: an eccentric wheel, which is fixed on the outer wall of the rotating rod and can rotate synchronously with the rotating rod to generate compressive force; The L-shaped rod slides on the top of the heating tank and passes through the top of the heating tank, with a sliding connection at the penetration point. The bottom of the L-shaped rod is a slope, and the L-shaped rod can be periodically squeezed and slid back and forth by an eccentric wheel. A heat-conducting block is fixed to the outer wall of the bracket. The heat-conducting block is attached to the end of the L-shaped rod. The heat-conducting block can generate heat through the reciprocating friction of the L-shaped rod on its outer wall.

[0012] According to the above technical solution, a spring seat is fixed to the outer wall of the heat-conducting block, a return spring is fixed to the bottom of the spring seat, and the end of the return spring is fixed to the top of the L-shaped rod. The return spring is used to drive the L-shaped rod to reset when it is not squeezed to achieve reciprocating motion. A copper block is fixed to the bottom of the storage box. The copper block is in contact with the top of the heat-conducting block and is used to conduct the heat of the heat-conducting block to the inside of the storage box.

[0013] According to the above technical solution, the present invention provides a stirring tank for synthesizing aluminum alloy surface treatment additives. It has the following beneficial effects: 1. This invention, by setting up a storage box, baffle, ejector spring, inclined block and feed pipe, allows powder to be loaded into the storage box. After the powder is loaded into the storage box, the baffle is lifted upwards. The ejector spring drives the inclined block to extend and lock the baffle. The powder enters the feed pipe through the outlet of the storage box and falls into the heating tank. This solves the problem that solid powder is easily stirred up and splashed when it is put in, which wastes raw materials and endangers the health of operators.

[0014] 2. This invention, by setting up a rotating rod and a drive motor to start and rotate the stirring rod, simultaneously rotates the rotating rod. As the rotating rod rotates, it continuously rotates the rotating rod inside the feed pipe, breaking up the powder inside the feed pipe. This solves the problem of powder accumulating and clogging when falling into the feed pipe, resulting in slow feeding speed.

[0015] 3. By setting up a scattering plate, a scattering port, and a stirring rod, the powder in the feed pipe falls into the scattering plate. When the rotating rod rotates, the stirring rod rotates synchronously. The rotating stirring rod stirs the material on the scattering plate, and the material is evenly sprinkled from the scattering port into the heating tank, which solves the problem of slow mixing speed caused by the concentrated falling of powder during the falling process.

[0016] 4. This invention, by setting up an eccentric wheel, an L-shaped rod, a heat-conducting block, a return spring, a spring seat, and a copper block, allows the rotating rod to drive the eccentric wheel to rotate while periodically squeezing the L-shaped rod. When the L-shaped rod rises along the heating tank, it contacts the heat-conducting block and slides back and forth, generating heat. The heat is then evenly conducted to the storage box through the copper block, solving the problem of powder in the storage box becoming damp and clumping, resulting in poor flowability.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6One embodiment of the present invention is as follows: a stirring tank for synthesizing aluminum alloy surface treatment additives includes a heating tank 1. An inlet pipe 2 is fixed to the outer wall of the heating tank 1, penetrating the outer wall of the heating tank 1 and fixedly connected at the penetration point. A drive motor 4 is fixed to the bottom of the heating tank 1, with its output end penetrating the bottom of the heating tank 1 and rotatably connected at the penetration point. An outlet pipe 5 is fixed to the bottom of the heating tank 1, penetrating the bottom of the heating tank 1 and fixedly connected at the penetration point. A one-way valve is fixed to the outer wall of the outlet pipe 5. A stirring rod 6 is fixed to the output end of the drive motor 4. A control panel 7 is fixed to the outer wall of the heating tank 1. A bracket 8 is fixed to the top of the heating tank 1, providing support for the installation of a storage box 9. The storage box 9 is fixed to the outer wall of the bracket 8. An inlet is provided at the top of the storage box 9, allowing solid powders such as metal salts to be poured into the storage box 9. An outlet is provided at the bottom of the storage box 9, allowing the metal salts to be discharged. After the solid powder leaves the storage box 9 through the discharge port, the baffle 10 slides on the inner wall of the storage box 9. The baffle 10 is used to block the discharge port of the storage box 9 and control the opening and closing of the discharge port. The outer wall of the baffle 10 has a slot, which provides installation space for the ejector spring 11 and the inclined block 12. The ejector spring 11 is fixed inside the slot of the baffle 10. The ejector spring 11 is used to eject the inclined block 12 when it is not squeezed, and when the inclined block 12 moves downward... When compressed, it provides power for the subsequent spring. The end of the ejector spring 11 is fixed with a ramp block 12. The ramp block 12 slides on the inner wall of the slot. The ramp block 12 is used to fix the baffle 10. The feed pipe 13 is fixed to the top of the heating tank 1. The feed pipe 13 is located below the outlet of the storage box 9. The feed pipe 13 passes through the top of the heating tank 1 and is fixedly connected at the penetration point. The feed pipe 13 is used to transport the solid powder from the storage box 9 to the heating tank 1 to prevent dust leakage.

[0021] By setting up a storage box 9, a baffle 10, an ejector spring 11, an inclined block 12, and a feed pipe 13, after the powder is loaded into the storage box 9, the baffle 10 is lifted upwards. The ejector spring 11 drives the inclined block 12 to extend and lock the baffle 10. The powder enters the feed pipe 13 through the outlet of the storage box 9 and falls into the heating tank 1. This solves the problem that solid powder is easily stirred up when it is put in, which causes dust to splash, wastes raw materials, and endangers the health of operators.

[0022] A rotating rod 14 is fixed to the top of the stirring rod 6, which can rotate with the stirring rod 6 to transmit power. A rotating rod 15 is fixed to the outer wall of the rotating rod 14. Multiple sets of rotating rods 15 are provided. The rotating rods 15 are used to unclog the feed pipe 13, disperse the powder in the feed pipe 13, and prevent the feed from getting blocked.

[0023] By setting up the rotating rod 14 and the rotating rod 15, the drive motor 4 starts and drives the stirring rod 6 to rotate. While the stirring rod 6 rotates, it drives the rotating rod 14 to rotate synchronously. When the rotating rod 14 rotates, it drives the rotating rod 15 to rotate continuously inside the feed pipe 13, which disperses the powder inside the feed pipe 13. This solves the problem of powder accumulating and blocking when falling into the feed pipe 13 and the slow feeding speed.

[0024] In this embodiment, during operation: when it is necessary to synthesize aluminum alloy surface treatment additives, deionized water and other liquids are transported into the heating tank 1 through the liquid inlet pipe 2. After the liquid is transported, the drive motor 4 is started through the control panel 7. The drive motor 4 drives the stirring rod 6 to rotate and stir the liquid. At the same time, materials containing solid powders such as metal salts are transported into the storage box 9 through the feed port at the top of the storage box 9. The baffle 10 blocks the discharge port of the storage box 9. When it is necessary to feed and mix, the baffle 10 is lifted upwards. During the upward lifting process, the inclined block 12 is no longer squeezed by the inner wall of the storage box 9, and the inclined block 12 springs back. The spring 11 extends outward under its elastic force and locks onto the top of the storage box 9, locking the baffle 10. After the baffle 10 is lifted, the outlet of the storage box 9 is no longer blocked, and the material in the storage box 9 flows into the feed pipe 13 below. At the same time, when the stirring rod 6 rotates, the rotating rod 14 rotates synchronously. The rotating rod 14, along with the rotating rod 15 on the outer wall, rotates continuously inside the feed pipe 13, breaking up the falling powder. The material enters the interior of the heating tank 1, and the solid material and liquid material are initially fused together. After the material is added, the heating tank 1 is started through the control panel 7. The heating tank 1 fuses the solid material and liquid material inside together through stirring and heating.

[0025] After the materials are mixed, open the one-way valve of the liquid outlet pipe 5. The mixed materials flow out through the liquid outlet pipe 5. At the same time, press down on the baffle 10. The baffle 10 moves down and moves the inclined block 12 down in sync. The inclined surface of the inclined block 12 is squeezed by the top of the storage box 9, compressing the ejector spring 11. The inclined block 12 and the ejector spring 11 enter the slot of the baffle 10, and the device completes one operation.

[0026] Please see Figures 1-6 Based on the above embodiments, in another embodiment of the present invention, a dispersing device is provided inside the heating tank 1, which is used to evenly sprinkle solid powder such as metal salt onto the heating tank 1. The scattering device includes: a scattering disc 201, a scattering port 202, and a stirring rod 203. The scattering disc 201 is fixed to the bottom of the feed pipe 13 and is used to receive the falling material. The scattering port 202 is opened at the bottom of the scattering disc 201 and is used to discharge solid powders such as metal salts that fall onto the scattering disc 201. The stirring rod 203 is fixed to the outer wall of the rotating rod 14 and is used to stir the powder on the scattering disc 201. The powder falls downward through the scattering port 202, achieving uniform material spreading.

[0027] By setting up a scattering plate 201, a scattering port 202, and a stirring rod 203, after the powder in the feed pipe 13 falls into the scattering plate 201, the stirring rod 203 rotates synchronously when the rotating rod 14 rotates. The rotating stirring rod 203 stirs the material on the scattering plate 201, and the material is evenly sprinkled from the scattering port 202 into the heating tank 1, which solves the problem of slow mixing speed caused by the concentrated falling of powder during the falling process.

[0028] The heating tank 1 is also equipped with an anti-piling device, which is used to prevent solid powders such as metal salts in the storage box 9 from accumulating due to moisture. The anti-stacking device includes: an eccentric wheel 301, an L-shaped rod 302, a heat-conducting block 303, a return spring 304, a spring seat 305, and a copper block 306. The eccentric wheel 301 is fixed to the outer wall of the rotating rod 14 and can rotate synchronously with the rotating rod 14, generating a compressive force that causes the L-shaped rod 302 to slide. The L-shaped rod 302 slides on the top of the heating tank 1 and passes through the top of the heating tank 1, with a sliding connection at the penetration point. The bottom of the L-shaped rod 302 is a slope, allowing it to slide back and forth periodically under the pressure of the eccentric wheel 301. The heat-conducting block 303 is fixed to the outer wall of the support 8, and the heat-conducting block 303 is attached to the end of the L-shaped rod 302. The heat-conducting block 303 generates heat through the reciprocating friction of the L-shaped rod 302 on its outer wall. A spring seat 305 is fixed to the outer wall of the heat-conducting block 303. The spring seat 305 is used to provide mounting support for the return spring 304. The return spring 304 is fixed to the bottom of the spring seat 305. The end of the return spring 304 is fixed to the top of the L-shaped rod 302. The return spring 304 is used to drive the L-shaped rod 302 to reset when it is not squeezed to achieve reciprocating motion. A copper block 306 is fixed to the bottom of the storage box 9. The copper block 306 is in contact with the top of the heat-conducting block 303. The copper block 306 is used to conduct the heat of the heat-conducting block 303 to the storage box 9.

[0029] By setting up an eccentric wheel 301, an L-shaped rod 302, a heat-conducting block 303, a return spring 304, a spring seat 305, and a copper block 306, the rotating rod 14 drives the eccentric wheel 301 to rotate while periodically squeezing the L-shaped rod 302. When the L-shaped rod 302 rises along the heating tank 1, it contacts the heat-conducting block 303 and slides back and forth to generate heat. The heat is evenly conducted to the storage box 9 through the copper block 306, which solves the problem of powder in the storage box 9 becoming damp and clumping, and the problem of poor fluidity.

[0030] In this embodiment, when the powder falls into the heating tank 1 through the feed pipe 13, the powder falls onto the dispersion plate 201. At the same time, when the stirring rod 6 rotates, the rotating rod 14 rotates synchronously. The rotating rod 14 carries the stirring rod 203 to rotate on the dispersion plate 201. When the stirring rod 203 rotates, it evenly sprinkles the powder scattered on the top of the dispersion plate 201 from the discharge port at the bottom of the dispersion plate 201, and evenly sprinkles it on the liquid.

[0031] Simultaneously, as the rotating rod 14 rotates, the rotating rod 14 drives the eccentric wheel 301 to rotate synchronously. The convex surface of the eccentric wheel 301 presses against the bottom inclined surface of the L-shaped rod 302, pushing the L-shaped rod 302 to slide upward along the heating tank 1. As the L-shaped rod 302 slides, its end slides on the surface of the heat-conducting block 303. At the same time, the L-shaped rod 302 compresses the return spring 304. When the convex surface of the eccentric wheel 301 leaves, the return spring 304 releases its elastic force. The return spring 304 carries the L-shaped rod 302 downward along the heating tank 1, and the L-shaped rod 302 returns to its initial position. When the convex surface of the eccentric wheel 301 returns, it presses the L-shaped rod 302 to rise again. This process of repeated friction and sliding on the surface of the heat-conducting block 303 generates heat. The heat from the heat-conducting block 303 is conducted to the copper block 306, and the heat from the copper block 306 is conducted to the interior of the storage box 9.

[0032] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
