Description

Technical Field

[0001] This invention relates to the field of Dacromet coating passivation equipment technology, specifically to a Dacromet coating passivation device. Background Technology

[0002] Dacromet coating passivation equipment is a surface treatment device primarily used to form a protective Dacromet coating on metal surfaces to improve the corrosion resistance of metal parts. Dacromet coating is an inorganic coating, typically composed of inorganic salts of metals such as zinc, aluminum, iron, and chromium. It protects the metal material by forming a corrosion-resistant protective layer on the metal surface. This coating provides excellent corrosion resistance and has wide applications in marine, high-humidity, and chemically corrosive environments.

[0003] In the prior art, Chinese patent document CN116463618B discloses a Dacromet coating passivation device, which utilizes the interaction of electromagnetic fields and springs to separate gas and liquid and pressurize the passivation liquid, thereby improving the passivation reaction speed of the Dacromet coating. It uses contact conductive short circuit to realize automatic control of the internal opening state of the device, and uses the floating characteristics to realize liquid surface feedback and self-identification. It significantly improves the passivation efficiency of metal parts by using high hydraulic pressure and slow rotating circulating liquid flow, and ensures that the passivation coating can be stably attached to the surface of the metal parts.

[0004] However, when the receiving basket is removed from the passivation liquid in the passivation cylinder, it may cause the receiving basket to carry the passivation liquid inside the passivation cylinder out with it. This can easily cause the passivation liquid to flow out from the top opening of the passivation cylinder, which will not only cause a lot of waste of passivation liquid and increase the cost of equipment passivation processing, but also cause the outflowing passivation liquid to drip onto the equipment surface and the work site, causing site pollution. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a Dacromet coating passivation device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a Dacromet coating passivation device, comprising a passivation cylinder, a support block fixed to the side wall of the passivation cylinder, an electric telescopic rod passing through the support block and fixedly connected at the passage, an L-shaped rod fixed to the output end of the electric telescopic rod, a connecting cylinder fixed to the end of the L-shaped rod, a connecting sleeve slidably installed on the inner wall of the connecting cylinder, a sealing cover fixed to the bottom of the connecting sleeve, an installation hook fixed to the bottom of the sealing cover, an installation sleeve attached to the installation hook, and the installation sleeve hinged to the outer wall of the receiving basket; A collection hood is fixed to the outer wall of the passivation cylinder and is used to collect the passivation liquid brought out by the receiving basket. A sealing sleeve is slidably installed on the top inner side of the passivation cylinder. A sealing groove is provided at the bottom of the sealing cover. The size of the sealing groove matches the size of the sealing sleeve, and the cooperation between the sealing groove and the sealing sleeve can be used to seal the top of the passivation cylinder. The passivation cylinder has a drain hole on its outer wall, which is used to discharge the passivation liquid collected in the collection hood into the passivation cylinder.

[0007] According to the above technical solution, a guide rod is slidably installed on the inner side of the passivation cylinder, and the top of the guide rod is fixedly connected to the bottom of the sealing sleeve.

[0008] According to the above technical solution, a connecting spring is fixed at the bottom of the guide rod, the bottom of the connecting spring is fixed inside the passivation cylinder, a spring plate is fixed inside the connecting cylinder, and the bottom of the spring plate is fixed at the top of the connecting sleeve.

[0009] According to the above technical solution, the support block is provided with a squeezing device, which is used to make the receiving basket vibrate.

[0010] According to the above technical solution, the extrusion device includes: an L-shaped frame, the L-shaped frame being fixed to the side wall of the support block, an extrusion rod passing through the L-shaped rod and slidably connected at the passage, a connecting plate being fixed to the outer wall of the extrusion rod, a return spring being fixed to the side wall of the connecting plate, and the side of the return spring away from the connecting plate being fixed to the outer wall of the L-shaped rod.

[0011] According to the above technical solution, a triangular block is fixed to the top of the sealing cover, and an inclined block is fixed to the side wall of the connecting plate.

[0012] According to the above technical solution, a hinge seat is fixed on the inner side of the L-shaped frame, a stop block is rotatably installed on the inner side of the hinge seat, a torsion spring is fixed on the outer wall of the stop block, the side of the torsion spring away from the stop block is fixed on the inner side of the hinge seat, and an inclined surface is provided at the bottom end of the stop block, so that when the inclined surface of the inclined block contacts the inclined surface of the stop block, the inclined block will be able to move under the squeezing force.

[0013] According to the above technical solution, a limiting block is fixed on the inner side of the L-shaped frame, and the limiting block is used to limit the rotation direction of the stop block.

[0014] This invention provides a Dacromet coating passivation apparatus. It has the following beneficial effects: 1. This invention, by setting up a collection hood, can collect the passivation liquid brought out by the receiving basket, preventing it from easily dripping onto the ground, causing waste and pollution. By setting up a drain hole, the passivation liquid collected in the collection hood can be collected into the passivation cylinder, allowing the passivation liquid to be reused and preventing waste. When the sealing cover moves downward, it can squeeze the sealing sleeve downward, so that the sealing sleeve can block and seal the drain hole, keeping the passivation cylinder in a sealed state for passivation operation.

[0015] 2. In this invention, when the sealing cap moves downward, the sealing groove at the bottom of the sealing cap allows it to engage with the sealing sleeve, pressing the sealing groove against the top of the sealing sleeve. When the sealing groove presses the sealing sleeve downward, the guide rod compresses the connecting spring. Because the connecting spring is in a compressed state, the sealing sleeve is pressed against the inner side of the sealing groove, thereby improving the sealing performance between the sealing cap and the top of the passivation cylinder.

[0016] 3. This invention, through the arrangement of an L-shaped frame, a pressing rod, a triangular block, a connecting plate, an inclined block, a return spring, a hinge seat, a stop block, a spring sheet, and a torsion spring, enables the receiving basket to vibrate continuously when the sealing cover pulls the receiving basket upward from the passivation cylinder. This vibration helps to effectively shake off the passivation liquid adhering to the surface of the receiving basket, thereby achieving rapid drainage and preventing passivation liquid residue. When the receiving basket moves into the passivation cylinder to prepare for passivation treatment, the inclined block presses against the stop block and causes it to rotate, thus preventing the inclined block from being displaced due to compression. As a result, the entire receiving basket does not vibrate, preventing the objects inside the receiving basket from colliding and piling up due to vibration during the descent into the passivation liquid. This avoids the objects being unable to fully contact the passivation liquid due to stacking, ensuring that the passivation effect is not affected. Attached Figure Description

[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 1-5 One embodiment of the present invention is as follows: a Dacromet coating passivation device, comprising a passivation cylinder 1, a support block 2, an L-shaped rod 3, a connecting cylinder 4, a connecting sleeve 5, an electric telescopic rod 6, a sealing cover 7, a receiving basket 8, a collection cover 9, a drain hole 10, a guide rod 11, a connecting spring 12, a sealing sleeve 13, a mounting hook 14, a mounting sleeve 15, and a spring plate 16; the support block 2 is fixed to the side wall of the passivation cylinder 1, the electric telescopic rod 6 passes through the support block 2 and is fixedly connected at the passage, the output end of the electric telescopic rod 6 is fixed to the L-shaped rod 3, the end of the L-shaped rod 3 is fixed to the connecting cylinder 4, the connecting sleeve 5 is slidably installed on the inner wall of the connecting cylinder 4, the sealing cover 7 is fixed to the bottom of the connecting sleeve 5, the receiving basket 8 is provided at the bottom of the sealing cover 7, the mounting hook 14 is fixed to the bottom of the sealing cover 7, the mounting sleeve 15 is attached to the mounting hook 14, and the mounting sleeve 15 is hinged to the outer wall of the receiving basket 8. The collection cover 9 is fixed to the outer wall of the passivation cylinder 1. The collection cover 9 is used to collect the passivation liquid brought out by the receiving basket 8. The sealing sleeve 13 is slidably installed on the top inner side of the passivation cylinder 1. The bottom of the sealing cover 7 is provided with a sealing groove. The size of the sealing groove matches the size of the sealing sleeve 13. The cooperation between the sealing groove and the sealing sleeve 13 can be used to seal the top of the passivation cylinder 1. The outer wall of the passivation cylinder 1 is provided with a drain hole 10. The drain hole 10 is used to discharge the passivation liquid collected in the collection cover 9 into the passivation cylinder 1. A guide rod 11 is slidably installed on the inner side of the passivation cylinder 1. The top of the guide rod 11 is fixedly connected to the bottom of the sealing sleeve 13. A connecting spring 12 is fixed to the bottom of the guide rod 11. The bottom of the connecting spring 12 is fixed to the inner side of the passivation cylinder 1. A spring plate 16 is fixed to the inner side of the connecting cylinder 4. The bottom of the spring plate 16 is fixed to the top of the connecting sleeve 5.

[0021] By setting up a collection hood 9, the passivation liquid brought out by the receiving basket 8 can be collected, preventing the solution from dripping onto the ground, causing waste and pollution. By setting up a drain hole 10, the passivation liquid collected in the collection hood 9 can be collected into the passivation cylinder 1, allowing the passivation liquid to be reused and preventing waste. When the sealing cover 7 moves downward, it can squeeze the sealing sleeve 13 downward, so that the sealing sleeve 13 can block and seal the drain hole 10, keeping the passivation cylinder 1 in a sealed state for passivation operation.

[0022] Furthermore, when the sealing cover 7 moves downward, the sealing groove at the bottom of the sealing cover 7 allows it to engage with the sealing sleeve 13, pressing the sealing groove against the top of the sealing sleeve 13. As the sealing groove presses the sealing sleeve 13 downward, the guide rod 11 compresses the connecting spring 12. Because the connecting spring 12 is in a compressed state, the sealing sleeve 13 is pressed against the inside of the sealing groove, thereby improving the sealing performance between the sealing cover 7 and the top of the passivation cylinder 1.

[0023] In this embodiment, when an object needs to be passivated, the object is placed in the receiving basket 8, the mounting sleeve 15 is put on the mounting hook 14, the receiving basket 8 is placed on the sealing cover 7, and the electric telescopic rod 6 is activated, which moves the L-shaped rod 3 downward, thereby causing the connecting cylinder 4 to move downward. When the connecting cylinder 4 moves downward, it can move the connecting sleeve 5 downward, which in turn moves the sealing cover 7 downward, thereby causing the receiving basket 8 to extend into the passivation cylinder 1 for passivation. At the same time as the sealing cover 7 moves downward, the sealing groove on the sealing cover 7 can be fitted onto the sealing sleeve 13. When the sealing cover 7 moves downward, the sealing groove can squeeze the sealing sleeve 13, which can squeeze the sealing sleeve 13 downward. This causes the sealing sleeve 13 to move downward, which in turn moves the guide rod 11 downward, compressing the connecting spring 12. When the sealing cover 7 moves downward to the top of the passivation cylinder 1 and contacts it, the sealing sleeve 13 can be squeezed inside the sealing groove, improving the sealing between the sealing cover 7 and the passivation cylinder 1. After the object is passivated, the electric telescopic rod 6 is activated, which moves the L-shaped rod 3 upward. When the L-shaped rod 3 moves upward, it moves the sealing cover 7 upward, so that the sealing groove of the sealing cover 7 does not squeeze the sealing sleeve 13. Because the connecting spring 12 is in a compressed state, the guide rod 11 moves the sealing sleeve 13 upward, so that the sealing sleeve 13 does not block the drain hole 10. When the receiving basket 8 is removed from the passivation cylinder 1, the passivation liquid is carried out. The passivation liquid carried out from the top opening of the passivation cylinder 1 can flow into the collection hood 9 for collection. The passivation liquid collected by the collection hood 9 can be discharged back into the passivation cylinder 1 through the drain hole 10 for collection again. When the sealing cover 7 moves downward and contacts the passivation cylinder 1, the sealing cover 7 squeezes the sealing sleeve 13 downward, so that the sealing sleeve 13 can seal and block the drain hole 10.

[0024] Please see Figures 1-5 Based on the above embodiments, in another embodiment of the present invention, a pressing device is provided on the support block 2. The pressing device is used to vibrate the receiving basket 8. The pressing device includes: an L-shaped frame 201, which is fixed to the side wall of the support block 2; a pressing rod 202 passes through the L-shaped rod 3 and is slidably connected at the through point; a connecting plate 204 is fixed to the outer wall of the pressing rod 202; a return spring 206 is fixed to the side wall of the connecting plate 204; the side of the return spring 206 away from the connecting plate 204 is fixed to the outer wall of the L-shaped rod 3; a triangular block 203 is fixed to the top of the sealing cover 7; and the side wall of the connecting plate 204... An inclined block 205 is fixed, and a hinge seat 207 is fixed on the inner side of the L-shaped frame 201. A stop block 208 is rotatably mounted on the inner side of the hinge seat 207. A torsion spring 209 is fixed on the outer wall of the stop block 208. The side of the torsion spring 209 away from the stop block 208 is fixed on the inner side of the hinge seat 207. An inclined surface is provided at the bottom end of the stop block 208. When the inclined surface of the inclined block 205 contacts the inclined surface of the stop block 208, the inclined block 205 will be able to move under the pressure. A limiting block 210 is fixed on the inner side of the L-shaped frame 201. The limiting block 210 is used to limit the rotation direction of the stop block 208.

[0025] By setting up structures such as L-shaped frame 201, extrusion rod 202, triangular block 203, connecting plate 204, inclined block 205, return spring 206, hinge seat 207, stop block 208, spring plate 16, torsion spring 209, and limiting block 210, when the sealing cover 7 drives the receiving basket 8 to be taken out of the passivation cylinder 1, the receiving basket 8 can generate continuous vibration. The vibration helps to effectively shake off the passivation liquid adhering to the surface of the receiving basket 8, thereby achieving rapid drainage of the receiving basket 8 and avoiding passivation liquid residue. When the containment basket 8 moves into the passivation cylinder 1 in preparation for passivation, the inclined block 205 will squeeze the stop block 208 and cause it to rotate. This will prevent the inclined block 205 from being squeezed and displaced, so the entire containment basket 8 will not vibrate. This will prevent the contents of the containment basket 8 from colliding and piling up due to vibration during its descent into the passivation liquid. This will prevent the contents from being unable to fully contact the passivation liquid due to piling up, and ensure that the passivation effect is not affected.

[0026] In this embodiment, when the sealing cover 7 moves upward, it drives the connecting plate 204 to move upward. When the connecting plate 204 moves upward, it drives the inclined block 205 to move upward, causing the inclined surface of the inclined block 205 to press against the inclined surface of the stop block 208. This causes the inclined block 205 to be subjected to compressive force, moving it towards the L-shaped rod 3. This compresses the return spring 206, and the connecting plate 204 drives the compression rod 202 to move, causing the compression rod 202 to press against the inclined surface of the triangular block 203. This compressive force causes the triangular block 203 to move downward, thus moving the sealing cover 7 downward and causing the connecting sleeve... 5 moves outward from the connecting cylinder 4, causing the spring plate 16 to stretch and deform, and causing the connecting sleeve 5 to drive the receiving basket 8 to move downward. When the inclined block 205 moves to a position where it does not contact the stop block 208, and because the return spring 206 is in a compressed state, the return spring 206 can drive the connecting plate 204 to reset, thereby resetting the extrusion rod 202 and preventing the extrusion rod 202 from extruding the inclined surface of the triangular block 203. Because the spring plate 16 is in a stretched state, the spring plate 16 can drive the connecting sleeve 5 to reset upward, thereby resetting the receiving basket 8. Thus, when the receiving basket 8 is removed from the passivation cylinder 1, the receiving basket 8 can vibrate up and down on the sealing cover 7, which can shake off the passivation liquid attached to the receiving basket 8. Furthermore, when the electric telescopic rod 6 drives the receiving basket 8 downward into the passivation cylinder 1 for passivation, the connecting plate 204 will cause the inclined block 205 to press against the top of the stop block 208, thereby causing the stop block 208 to rotate downward under the pressure, compressing the torsion spring 209, and preventing the inclined block 205 from moving the connecting plate 204. As a result, the receiving basket 8 will not vibrate when it moves into the passivation cylinder 1.

[0027] 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.
