Description

Technical Field

[0001] This utility model relates to the technical field of graphite electrode processing equipment, specifically to a graphite electrode spraying mechanism that provides uniform spraying. Background Technology

[0002] The importance of the spraying process in the production and processing of graphite electrodes is self-evident. However, existing graphite electrode spraying mechanisms have some significant problems in use.

[0003] For the spraying of graphite electrode surfaces, achieving uniformity has always been a difficult problem. Due to unreasonable spraying methods and equipment limitations, the spray liquid often cannot evenly cover the entire surface of the graphite electrode. This leads to over-spraying in some areas, which not only wastes the spray liquid but may also cause local performance changes in the graphite electrode, affecting its overall quality. Insufficient spraying fails to achieve the expected treatment effect. Uneven spraying severely restricts the performance improvement of graphite electrodes, making the product prone to various problems in subsequent use. More time and resources are needed to make up for the defects caused by uneven spraying. Uneven spraying also causes uneven wear on production equipment, shortens the effective service life of the equipment, and increases the cost of equipment maintenance and replacement.

[0004] For example, a boiler spraying device for graphite electrode production, as disclosed in announcement number CN217585338U, includes a base. A water pump and a water tank are fixedly connected to the upper end of the base. A fixed plate is fixedly connected to the outer surface of the water tank and the base. A telescopic pipe is slidably connected to the middle of the fixed plate. A water outlet pipe is provided on the outer surface of the telescopic pipe. An injector is connected to the surface of the water outlet pipe. An electromagnetic valve body is fixedly connected to the upper end of the injector. In use, the above-mentioned boiler spraying device for graphite electrode production suffers from uneven graphite electrode spraying, resulting in poor treatment effect, increased energy consumption, equipment wear, and increased costs. However, it also has other problems. For example, in the treatment of the spraying liquid, traditional methods cannot guarantee the uniform mixing of its components. This makes the performance of the spraying liquid unstable during use, and it is impossible to maintain a consistent treatment effect. Uneven composition can easily lead to the local aggregation of certain components, which in turn causes precipitation and stratification. This not only reduces the effective utilization rate of the spraying liquid, but also, due to the uneven composition, it is impossible to guarantee the smooth progress of chemical reactions in some processes that require specific chemical environments, thus affecting the final quality and performance of the product. Utility Model Content

[0005] The purpose of this invention is to provide a graphite electrode spraying mechanism that provides uniform spraying, in order to solve the problems mentioned in the background art, such as uneven surface of the graphite electrode spraying, resulting in poor treatment effect, increased energy consumption, equipment wear and increased cost, and uneven mixing of spray liquid components, leading to unstable performance, low utilization rate, easy precipitation and stratification, and affecting chemical reactions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniformly sprayed graphite electrode spraying mechanism, comprising a support plate and a graphite electrode body disposed on the upper end of the support plate; the support plate is C-shaped, a first motor is fixedly installed on the left end of the support plate, and a rotating stud is fixedly installed on the output end of the first motor, and the rotating stud is rotatably installed on both sides of the lower end of the support plate; a guide groove is provided on the upper end of the support plate, a uniform spraying mechanism is provided on the upper end of the support plate, and a moving block is installed on the rotating stud, and the moving block is installed inside the support plate, and the front end of the moving block cooperates with the guide groove; a water tank is provided at the rear end of the support plate, and a spraying agent port is provided on the front side of the upper end of the water tank, and a second motor is fixedly installed on the upper end of the water tank, a first eccentric wheel is fixedly installed on the output end of the second motor, and the first eccentric wheel is installed inside the water tank; a stirring mechanism is provided at the rear end of the support plate, and a rotating shaft is rotatably installed on the outer side of the first eccentric wheel.

[0007] Furthermore, the uniform spraying mechanism includes a movable plate fixedly installed on the upper end of the movable block, and the movable plate is installed on the outside of the graphite electrode body, and a contact switch is provided on the upper end of the support plate.

[0008] Furthermore, the contact switch is connected to the first motor, and the contact switch cooperates with the moving plate, the moving plate having an annular tube inside.

[0009] Furthermore, an atomizing nozzle is provided on the inner side of the annular tube, and the atomizing nozzle on the annular tube corresponds to the outer side of the graphite electrode body, and a connecting pipe is installed through the rear end of the annular tube.

[0010] Furthermore, a water pump is fixedly installed at the other end of the connecting pipe, and a water pumping pipe is installed at the left end of the water pump, with the lower end of the water pumping pipe passing through and installed on the water tank.

[0011] Furthermore, the stirring mechanism includes a spur gear fixedly installed in the middle of the rotating shaft, and an internal gear fixedly installed at the upper end of the inside of the water tank, with the spur gear and the internal gear meshing with each other.

[0012] Furthermore, a second eccentric wheel is fixedly installed at the lower end of the rotating shaft, and a stirring rod is fixedly installed on the outer side of the second eccentric wheel, and the blades of the stirring rod are helical.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a graphite electrode spraying mechanism with uniform spraying;

[0014] 1. The output of the first motor drives the rotating stud to rotate, which in turn drives the moving block on it to move. The moving block slides along the guide groove on the support plate, so the annular tube inside the moving plate also moves with the moving plate. The spraying agent inside the water tank is drawn out through the water pumping pipe, so that the spraying agent is evenly sprayed on the graphite electrode, ensuring that the surface of the graphite electrode receives the spraying liquid evenly, thereby improving the overall quality and performance of the graphite electrode and reducing the potential pollution risk to the environment.

[0015] Furthermore, it effectively reduces material consumption and avoids material waste caused by local over- or under-treatment, thereby reducing production costs, improving resource utilization efficiency, providing a strong guarantee for high-quality production, significantly extending the service life of equipment, reducing local impact and wear on equipment, lowering the incidence of equipment failure, greatly enhancing environmental protection, reducing unnecessary waste of spray liquid, and reducing the pollution load on the environment.

[0016] Furthermore, it greatly enhances the cooling effect, enabling the graphite electrode to achieve uniform cooling from all directions without dead angles during the processing. This avoids internal stress and structural changes caused by temperature differences, ensuring stable product performance, significantly improving processing quality, and achieving a high degree of consistency and uniformity in the physical and chemical properties of the graphite electrode surface. This effectively improves product quality, reduces surface defects and performance fluctuations caused by uneven spraying, and lowers the defect rate.

[0017] 2. The output of the second motor drives the first eccentric wheel to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft drives the spur gear and the internal gear in the middle to cooperate, causing the spur gear to rotate. The spur gear drives the rotating shaft to rotate, which in turn drives the second eccentric wheel to rotate. The second eccentric wheel drives the outer stirring rod to rotate, so that the components of the sprayed agent are always evenly distributed, effectively promoting the chemical reaction and improving the reaction efficiency and conversion rate.

[0018] Furthermore, it ensures the consistency of the spraying effect, achieving a highly consistent treatment effect regardless of when or where the spraying is performed. This lays a solid foundation for the stability of product quality, keeps the liquid composition uniform, eliminates performance uncertainties caused by composition fluctuations, ensures the stability and reliability of the production process, prevents sedimentation and stratification, extends the effective storage and service life of the spraying liquid, and reduces production interruptions and losses caused by liquid deterioration.
