Description

Technical Field

[0001] This utility model relates to the field of rust prevention technology for cathode steel rods, specifically to a rust-preventive liquid spraying device for cathode steel rods. Background Technology

[0002] In industries such as aluminum electrolysis, cathode steel rods are extremely critical components. They play a vital role in current conduction within the aluminum electrolysis cell, significantly impacting the stability and efficiency of the entire electrolysis process. However, cathode steel rods face severe corrosion risks during use. To extend their service life and reduce the negative impacts of corrosion, rust-preventive spraying devices are required to treat them for rust prevention.

[0003] Currently, some existing rust-preventive liquid spraying devices for cathode steel rods may have dust and foreign matter adhering to the surface of the cathode steel rod during spraying. These impurities will affect the direct contact and full adhesion between the rust-preventive liquid and the surface of the cathode steel rod. Therefore, even if the rust-preventive liquid is sprayed, its rust-preventive effect will be greatly reduced, thus reducing the protective properties of the rust-preventive liquid. Meanwhile, some existing cathode steel rod rust-preventive liquid spraying devices keep the cathode steel rod stationary during the spraying process, which prevents the rust-preventive liquid from being evenly covered on its entire surface. This can lead to rust-preventive liquid accumulation in some parts of the cathode steel rod, while other parts may not be properly sprayed or have insufficient coating thickness. This not only wastes the rust-preventive liquid but also affects the rust-preventive effect. Utility Model Content

[0004] The purpose of this invention is to provide a rust-preventive liquid spraying device for cathode steel rods to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust-preventive liquid spraying device for cathode steel rods, comprising a workbench and a U-shaped plate fixedly connected to its top, and further comprising: The spraying mechanism is installed on the top of the U-shaped plate. Both sides of the inner surface of the U-shaped plate are rotatably connected to rotating rods. Several movable plates are fixedly connected to the outer surface of the rotating rods. A fixing mechanism is installed on the other side of the rotating rods. A jetting mechanism is installed on the top of the workbench to rotate and clean the cathode steel rod. A filter mechanism is also installed on the top of the workbench to process the dust blown down by the jetting mechanism.

[0006] Preferably, the jetting mechanism includes an air pump fixedly installed on the top of the workbench, the top of the air pump is connected to a plurality of jet heads through an air outlet pipe, and the top of the air pump is connected to high-pressure nozzles through both ends of the air outlet pipe.

[0007] Preferably, the filtration mechanism includes a processing box fixedly connected to the top of the workbench, the top of the processing box is connected to a dust collection hood through a dust suction pipe, and dust filter plates are fixedly installed on both sides of the inner surface of the processing box.

[0008] Preferably, both the jet head and the high-pressure nozzle are tapered in shape.

[0009] Preferably, one side of the rotating rod is rotatably connected to a bearing seat, and the other side of the bearing seat is fixedly connected to one side of the inner surface of the U-shaped plate.

[0010] Preferably, the movable plate is designed to be inclined.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes an air-jet mechanism to blow away dust and foreign matter adhering to the surface of the cathode steel rod. Simultaneously, the air-jet mechanism drives the movable plate, rotating rod, fixing mechanism, and fixed cathode steel rod to rotate, enabling thorough cleaning and preventing impurities from affecting the contact and adhesion of the rust-preventive liquid, thus preventing any impact on the subsequent rust-preventive effect. Furthermore, the rotation of the fixed cathode steel rod during spraying ensures even coverage of the rust-preventive liquid on its surface, effectively improving spray uniformity and quality. Additionally, the suction generated by the air-jet mechanism during cleaning collects and filters the blown-off dust, preventing it from falling back onto the cathode steel rod and causing further damage.

[0014] 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.

[0015] Please see Figure 1-4 As shown, a rust-preventive liquid spraying device for cathode steel rods includes a workbench 1. A U-shaped plate 2 is fixedly connected to the top of the workbench 1. A spraying mechanism 3 is installed on the top of the U-shaped plate 2. The rust-preventive liquid is drawn from the storage tank through a pump and a suction pipe by the spraying mechanism 3, and sprayed onto the cathode steel rod through an outlet pipe and a spray head for rust prevention treatment. Rotating rods 4 are rotatably connected to both sides of the inner surface of the U-shaped plate 2. A bearing seat is rotatably connected to one side of the rotating rod 4, and the other side of the bearing seat is fixedly connected to one side of the inner surface of the U-shaped plate 2. The base supports the rotating rod 4, improving its stability during rotation. Several movable plates 5 are fixedly connected to the outer surface of the rotating rod 4. These movable plates 5 are designed with an inclined shape. The inclined design of the movable plates 5 allows for the generation of normal and tangential forces when the airflow impacts the inclined surface, reducing frictional resistance and facilitating rotation. A fixing mechanism 6 is installed on the other side of the rotating rod 4. An electric push rod in the fixing mechanism 6 pushes the fixing plate to fix the cathode steel rod. The electric push rod is a lightweight electric push rod. The device is a lightweight electric actuator, electrically connected to the outside via a Senripu slip ring, weighing 65 grams, making it easy to push and ensuring greater stability during spraying. The top of the worktable 1 is equipped with an air jet mechanism 7 that can rotate and clean the cathode steel rod. This mechanism blows away dust and foreign matter adhering to the surface of the cathode steel rod. Simultaneously, the air jet mechanism 7 rotates the movable plate 5, rotating rod 4, fixing mechanism 6, and the fixed cathode steel rod, thoroughly cleaning them and preventing impurities from affecting the contact and adhesion of the rust-preventive liquid, thus preventing any impact on the subsequent rust-preventive effect. Furthermore, during spraying, the air jet mechanism 7 rotates the fixed cathode steel rod, ensuring even coverage of the rust-preventive liquid on its surface, effectively improving spray uniformity and quality. The top of the worktable 1 is equipped with a filter mechanism 8 that processes the dust blown down by the air jet mechanism 7. The suction generated by the air jet mechanism 7 during cleaning collects and filters the blown-down dust, preventing it from falling back onto the cathode steel rod and causing further damage.

[0016] The jetting mechanism 7 includes an air pump 701 fixedly mounted on the top of the workbench 1. Several jet nozzles 702 are connected to the top of the air pump 701 via an air outlet pipe. High-pressure nozzles 703 are connected to both ends of the air outlet pipe on the top of the air pump 701. Both the jet nozzles 702 and the high-pressure nozzles 703 are conical in shape. Through the jetting mechanism 7, the air pump 701 draws in air through connecting pipes, etc., and blows off dust and foreign objects adhering to the surface of the cathode steel rod through the air outlet pipe and jet nozzles 702. Simultaneously, the high-pressure nozzles 703 blow air to rotate the movable plate 5, which in turn drives the rotating rod 4 and the fixed... The mechanism 6 and the fixed cathode steel rod rotate to perform comprehensive cleaning. While spraying liquid, the high-pressure nozzle 703 can blow the fixed cathode steel rod to rotate for uniform spraying. The conical design of the jet nozzle 702 and the high-pressure nozzle 703 accelerates the Bernoulli effect of the airflow through the tapered channel, forming a high-speed, high-concentration airflow jet, reducing air diffusion and improving the cleaning effect of the jet nozzle 702. At the same time, the conical design reduces turbulence and pressure loss, making the energy of compressed air more efficiently converted into kinetic energy, and facilitating the rotation of the movable plate 5 and the rotating rod 4 by the high-pressure nozzle 703.

[0017] The filtration mechanism 8 includes a processing box 801 fixedly connected to the top of the workbench 1. The top of the processing box 801 is connected to a dust collection hood 802 via a suction pipe. Dust filter plates 803 are fixedly installed on both sides of the inner surface of the processing box 801. The bottom of the processing box 801 is connected to the suction end of the air pump 701 via a connecting pipe. Through the filtration mechanism 8, the air pump 701 will draw air through the connecting pipe, the processing box 801 and the dust collection hood 802. The suction force generated by the dust collection hood 802 can draw the blown dust into the processing box 801 and filter it through the dust filter plates 803.

[0018] It is worth noting that the technical features proposed in this technical solution, such as the spraying mechanism 3, the fixing mechanism 6, and the air pump 701, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0019] Working principle: First, place the cathode steel rod on one side of the fixing mechanism 6. Then, open the electric push rod in the fixing mechanism 6 to push the fixing plate to fix the cathode steel rod. Then, turn on the air pump 701. The air pump 701 draws air through the connecting pipe, the processing box 801, and the dust collection hood 802. The dust and foreign objects on the surface of the cathode steel rod are blown off through the air outlet pipe and the jet nozzle 702. At the same time, the high-pressure nozzle 703 blows the movable plate 5 to rotate. The movable plate 5 drives the rotating rod 4, the fixing mechanism 6, and the fixed cathode steel rod to rotate, which can thoroughly clean them. The dust blown off is sucked into the processing box 801 by the suction force generated by the air pump 701 on the dust collection hood 802 and then filtered through the dust plate 80. 3. After filtration, the delivery pump in the spraying mechanism 3 is turned on. The delivery pump suction pipe draws the rust inhibitor from the storage tank and sprays it onto the cathode steel rod through the outlet pipe and spray head for rust prevention. At the same time as spraying, the high-pressure nozzle 703 can blow the fixed cathode steel rod to rotate, so that the rust inhibitor can be evenly covered on the surface of the cathode steel rod. Before the high-pressure nozzle 703 blows the cathode steel rod to rotate, the solenoid valve on the air outlet pipe is opened to close the connection with the air jet 702. At the same time, the solenoid valve is used to close the dust suction pipe between the treatment box 801 and the dust collection hood 802, and the solenoid valve is used to open the air inlet pipe on the other side of the surface of the treatment box 801, so that air is blown only through the high-pressure nozzle 703 to prevent it from affecting the spraying.
