[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The described embodiments are merely 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.

[0030] like Figures 1-3 A pulverized coal spray gun for producing metallized anode plates includes a spray gun 1 with a gun core 9 inside. A connecting cover 6 is mounted on one end of the spray gun 1 via a detachable connection mechanism. The inner side of the connecting cover 6 is fixedly connected to one end of the gun core 9. The detachable connection mechanism includes rotating bolts 3 and nuts 4. One end of the rotating bolts 3 is fixed to the side wall of the spray gun 1, and the other end is inserted into a corresponding hole in the connecting cover 6. The rotating bolts 3 are symmetrically distributed along the axis of the gun core 9. This arrangement of bolts ensures a secure connection between the components of the spray gun 1. To improve the overall structural stability, the external thread of the rotating bolt 3 is connected to a nut 4. This connection method enables convenient disassembly and assembly, making equipment maintenance and component replacement more efficient. The external sliding connection of the rotating bolt 3 is a limiting washer 5, which prevents unnecessary movement of the equipment during use, thus enhancing the safety and reliability of the spray gun 1. A connecting cover 6 is installed on one side of the spray gun 1. The connecting cover 6 is not only an important part of the structure of the spray gun 1, but also supports multiple functional components, providing support for the overall design.

[0031] One side of the limiting gasket 5 contacts one side of the connecting cover 6. This design ensures that the connecting cover 6 will not slip under its own weight and during operation, thereby improving the smoothness and safety of operation. The gun core 9 is fixedly connected to one side of the connecting cover 6. The gun core 9 is the core component of the spray gun 1. Its design determines the flow state and spraying effect of pulverized coal during the spraying process. The gun core 9 is equipped with high-temperature resistant components. The presence of these components improves the spray gun 1's resistance to high-temperature environments and greatly extends the service life of the equipment. The high-temperature resistant components include a high-temperature resistant ceramic tube 10. The inner wall of the high-temperature resistant ceramic tube 10 is fixedly connected to the outside of the gun core 9. The strong connection method makes the two components tightly bonded to prevent displacement caused by vibration or impact.

[0032] The exterior of the high-temperature resistant ceramic tube 10 is provided with a high-temperature resistant adhesive 11. This adhesive not only enhances the adhesion between the ceramic tube and the gun core 9, but also maintains its adhesion performance in a high-temperature environment, ensuring the stability of the spray gun 1 when working at high temperatures. A silicone conical gasket 12 is installed on one side of the connecting cover 6. The use of the silicone gasket can effectively prevent gas leakage, improve the overall sealing of the spray gun 1, and ensure stable air pressure during the spraying process. A pipe 2 is fixedly connected to the top of the spray gun 1. The setting of the pipe 2 allows the pulverized coal to be smoothly transported to the spray gun 1, effectively improving the spraying efficiency. A baffle 7 is rotatably connected to the inner wall of the spray gun 1. The presence of the baffle 7 allows the operator to flexibly adjust the spray flow rate and spray angle to meet the needs of different working conditions.

[0033] A stop bar 8 is fixedly connected to the inner wall of the spray gun 1. The function of the stop bar 8 is to limit the range of motion of the baffle 7, ensuring that the nozzle will not be damaged or the spraying will be uneven due to misoperation. The inner wall of the spray gun 1 is provided with soft rubber 13. This layer of soft rubber 13 not only helps to reduce the vibration of the spray gun 1 during use, but also effectively absorbs the impact generated during spraying, improving the operator's comfort and safety.

[0034] When the gun core 9 needs to be replaced, simply turn the nut 4 to unscrew it from the rotating bolt 3. Since the limiting washer 5 is fixed to the side of the connecting cover 6 by the pressure of the nut 4, the restriction between the limiting washer 5 and the connecting cover 6 is released after the nut 4 is removed. At this time, the connecting cover 6 can be directly removed from the spray gun body 1 along with the gun core 9. When replacing the new gun core 9, insert the gun core 9 into the spray gun body 1, then reset the connecting cover 6, turn the rotating bolt 3 to make it snap into the groove of the connecting cover 6, then install the limiting washer 5 to make it contact the connecting cover 6, and finally tighten the nut 4 until the limiting washer 5 is fixed, thus completing the replacement of the gun core. The combination design of the high-temperature resistant ceramic tube 10 and the high-temperature resistant adhesive 11 ensures the stability of the gun core 9 in high-temperature environments. The use of the silicone conical washer 12 improves the sealing performance of the spray gun. This invention has a simple structure, is safe and reliable, enables rapid replacement of the spray gun core, improves production efficiency, and enhances the durability of the spray gun. Therefore, this device has good practicality.
