[0026] like Figure 1 and Figure 2 As shown, the automatic anti-rust paint spraying device for tall stainless steel chimneys provided in this embodiment includes: a hollow column 1, which is set between the fixed frame 3 and the chimney 13. A lifting device 2 is provided on the hollow column 1. The lifting device 2 is connected to a spraying device 4, a hose 5, and an air pipe 6. The spraying device 4 is located around the chimney 13, and the hose 5 and the air pipe 6 are located inside the hollow column 1. The hose 5 is connected to a cleaning liquid container 8 and an anti-rust paint container 9. The air pipe 6 is connected to a control box 7, and the control box 7 is also connected to the cleaning liquid container 8, the anti-rust paint container 9, and the spraying device 4.
[0027] The chimney 13 is composed of multiple sections of 304 stainless steel cylinders connected together by flanges and fixed to the foundation by a fixing frame 3. A rain cap 14 is installed on the top of the chimney 13.
[0028] Furthermore, a PLC controller is installed inside the control box 7. In one embodiment of this utility model, the PLC controller is model S7-300. It should be noted that this utility model does not specifically limit the type and model of the controller inside the control box 7. The hollow column 1 is made of stainless steel. It should be noted that this utility model does not specifically limit the material and installation position of the hollow column 1.
[0029] The cleaning fluid container 8 is used to hold cleaning fluid. In one embodiment of this invention, the cleaning fluid is water; in other embodiments, the cleaning fluid is alcohol. It should be noted that this invention does not specifically limit the composition of the cleaning fluid. The rust-preventive paint container 9 is used to hold rust-preventive paint.
[0030] Furthermore, the hollow column 1 has an opening groove 11 formed on its surface in the vertical direction, and a slide rail 12 is embedded in the opening groove 11. The lifting device 2 can slide up and down along the slide rail 12, thereby facilitating the up and down movement of the spraying device 4. The slide rail 12 can be welded to the hollow column 1 through the opening groove 11.
[0031] Furthermore, the lifting device 2 extends from the inside of the hollow column 1 to the outside of the hollow column 1, and the spraying device 4 is connected to the lifting device 2 extending to the outside of the hollow column 1; the hose 5 and the air pipe 6 are respectively connected to the lifting device 2 located inside the hollow column 1. Compressed air is supplied to the air pipe 6. When the spraying device 4 sprays cleaning fluid or rust-preventive paint, the spraying device 4 requires air to atomize the cleaning fluid or rust-preventive paint. Therefore, after the spraying device 4 operates, the air pipe 6 also operates, spraying compressed air from the air pipe 6. As soon as the hose 5 finishes operating, that is, after completing the delivery of cleaning fluid or rust-preventive paint, the air pipe 6 then also enters the operating state, starting to deliver compressed air to achieve the function of atomizing the cleaning fluid or rust-preventive paint.
[0032] Furthermore, the lifting device 2 is connected to a driving device, which includes a hydraulic press or a motor. It should be noted that this utility model does not specifically limit the type of driving device.
[0033] Furthermore, the cleaning fluid container 8 and the rust-preventive paint container 9 are respectively equipped with valves connected to the control box 7. In a specific implementation, when cleaning with cleaning fluid is required, the control box 7 controls the valve of the cleaning fluid container 8 to open and the valve of the rust-preventive paint container 9 to close; during paint spraying maintenance, the control box 7 controls the valve of the rust-preventive paint container 9 to open and the valve of the cleaning fluid container 8 to close.
[0034] Furthermore, a pump 10 is provided between the cleaning fluid container 8 and the rust-preventive paint container 9 and the hose 5. The pump 10 is connected to the control box 7. The pump 10 can pump the cleaning fluid in the cleaning fluid container 8 or the rust-preventive paint in the rust-preventive paint container 9. The control box 7 can control the operation of the pump 10.
[0035] Furthermore, the spraying device 4 includes an annular hollow tube 42 disposed around the chimney and connected to the flexible hose 5, with multiple nozzles 41 spaced apart on the annular hollow tube 42. The nozzles 41 can spray cleaning fluid or anti-rust paint. It should be noted that this invention does not specifically limit the number or distribution of the nozzles 41. The lifting device 2 has a hollow pipe inside, one end of which is connected to the flexible hose 5, and the other end is connected to the annular hollow tube 42. In a specific implementation, a three-way hollow tube head can be connected to each nozzle 41, and the nozzle 41 can be installed on the three-way hollow tube head.
[0036] During operation, the control box 7 controls the working status of the spraying device 4, lifting device 2, cleaning fluid container 8, and anti-rust paint container 9 to achieve automatic cleaning and anti-rust paint spraying of the chimney 13. The control box 7 can switch the connection status of the hose 5 with the cleaning fluid container 8 and the anti-rust paint container 9. When the hose 5 is connected to the cleaning fluid container 8, the spraying device 4 sprays cleaning fluid to clean the chimney 13. When the hose 5 is connected to the anti-rust paint container 9, the spraying device 4 sprays anti-rust paint onto the surface of the chimney 13. During the operation of the spraying device 4, the lifting device 2 moves the spraying device 4 up and down, thereby achieving self-cleaning and painting maintenance of the entire chimney 13.
[0037] In one embodiment of this utility model, the control box 7 first controls the cleaning fluid container 8 to open and sets the cleaning time. The chimney 13 is cleaned with cleaning fluid. When the set cleaning time is up, pressurized air is sprayed from the air pipe 6 to dry the surface of the chimney 13. Then, the control box 7 controls the anti-rust paint container 9 to open and starts automatically spraying paint onto the chimney 13. When the set cleaning time is up, pressurized air is sprayed from the air pipe 6 to dry the surface of the chimney 13. The process continues according to the set speed and number of reciprocations until completion.
[0038] Furthermore, this utility model also provides a chimney that employs the aforementioned automatic anti-rust paint spraying device for tall stainless steel chimneys.
[0039] The automatic rust-preventive paint spraying device and chimney for tall stainless steel chimneys provided in this utility model embodiment control the working status of the spraying device, lifting device, cleaning liquid container, and rust-preventive paint container through a control box to achieve automatic cleaning and automatic rust-preventive paint spraying of the chimney. Automatic painting maintenance can be carried out during production breaks. It can efficiently and automatically complete the self-cleaning and painting maintenance of tall chimneys, ensuring personal safety and equipment operation safety, thereby solving the problems of personnel safety and equipment operation safety faced by production enterprises.
