Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and specifically discloses a heavy-duty anti-corrosion coating equipment. Background Technology

[0002] Heavy-duty anti-corrosion coatings refer to a type of anti-corrosion coating that can be applied in relatively harsh corrosive environments and has a longer protection period than conventional anti-corrosion coatings. They require spraying operations using coating equipment.

[0003] Chinese patent application CN202222779402.9 discloses a heavy-duty anti-corrosion coating application device for preventing blockage; it includes a base plate, a paint tank rotatably connected to the upper end of the base plate, a nozzle pipe fixedly connected to the right end of the paint tank and communicating with it, an annular hollow pipe is provided inside the nozzle pipe, multiple air outlets are opened at the right end of the annular hollow pipe, a first circular pipe is fixedly connected to the upper end of the nozzle pipe, a second circular pipe is fixedly connected to the left end of the first circular pipe and communicating with it, the left end of the second circular pipe extends into the annular hollow pipe and is fixedly connected to the annular hollow pipe, a feed inlet is fixedly connected to the upper end of the base plate, and an air inlet pipe is fixedly connected to the right end of the first circular pipe. Its characteristic is that the airflow cleans the paint residue adhering inside the nozzle pipe, effectively ensuring the cleanliness of the inside of the nozzle pipe and effectively avoiding the occurrence of blockage.

[0004] When cleaning the inner wall of the nozzle pipe, the above-mentioned equipment requires cutting off the air supply to the paint tank and connecting a separate external air pipe to the air inlet pipe connected to the annular air pipe, which is quite troublesome to operate. In addition, when the equipment is used in a low-temperature environment, the fluidity of the heavy-duty anti-corrosion coating will decrease at low temperatures, which will affect the spraying effect of the equipment. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a heavy-duty anti-corrosion coating equipment, including a base plate, a protective sleeve rotatably connected inside the base plate, a paint tank made of stainless steel fixedly fitted inside the protective sleeve, a handle provided on the outside of the protective sleeve, a nozzle pipe connected to the outside of the top of the paint tank, and a feed inlet and an air inlet connected to the top of the paint tank, an annular hollow pipe with an internal air outlet provided inside the nozzle pipe, a first air inlet pipe connected to the outside of the annular hollow pipe, a two-position three-way ball valve connected to the outside of the top of the air inlet, a valve stem installed inside the two-position three-way ball valve, a second air inlet pipe connected to one side of the two-position three-way ball valve, and a guide pipe connected to the first air inlet pipe connected to the inside of the other side of the two-position three-way ball valve, a sealing cap threadedly fitted to the outside of the top of the feed inlet, and an electromagnetic heating coil installed on the top of the base plate between the protective sleeve and the paint tank.

[0006] Preferably, a valve is connected to the outer side of one end of the second air intake pipe, and the valve is connected to a high-pressure pipe.

[0007] Preferably, an infrared temperature sensor located below the paint tank is fixedly installed on the bottom inner side of the base plate.

[0008] The advantages of this utility model are as follows:

[0009] 1. This heavy-duty anti-corrosion coating equipment can cut off the connection between the air inlet and the second air inlet pipe by rotating the valve stem 90 degrees, while simultaneously connecting the second air inlet pipe to the guide pipe. This allows the high-pressure gas inside the high-pressure pipe to be transported to the interior of the annular tube through the guide pipe and the first air inlet pipe. After the high-pressure gas is discharged through the air outlet, it can clean the paint residue adhering to the inner wall of the nozzle pipe. This structure allows the air inlet and the annular tube to share a single high-pressure pipe, eliminating the need for an additional external air pipe for the annular tube, making it more convenient to operate.

[0010] 2. This heavy-duty anti-corrosion coating equipment uses an electromagnetic heating coil to simultaneously heat the paint tank and the heavy-duty anti-corrosion coating inside. Furthermore, an infrared temperature sensor detects and controls the temperature of the paint tank, ensuring that the electromagnetic heating coil heats the paint tank to the preset temperature. This structure allows the equipment to maintain the fluidity of the heavy-duty anti-corrosion coating even in low-temperature environments, thus ensuring that the coating effect is not affected.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0019] Please see Figure 1-4 A heavy-duty anti-corrosion coating equipment includes a base plate 1. A protective sleeve 2 is rotatably connected inside the base plate 1. A paint tank 3 made of stainless steel is fixedly fitted inside the protective sleeve 2. The protective sleeve 2 protects an electromagnetic heating coil 15 while allowing the paint tank 3 to rotate synchronously with the protective sleeve 2 without interfering with the rotation of the protective sleeve 2 and the paint tank 3. A handle 4 is provided on the outer side of the protective sleeve 2. A nozzle pipe 5 is connected to the outer side of the top of the paint tank 3, and a feed inlet 6 and an air inlet 7 are connected to the top of the paint tank 3. An annular hollow pipe 8 with an internal air outlet is provided inside the nozzle pipe 5. A first air inlet pipe 9 is connected to the outer side of the annular hollow pipe 8. A two-position three-way ball valve 10 is connected to the outer side of the top of the air inlet 7. The valve core inside the two-position three-way ball valve 10 uses a T-shaped hole, and the valve can be adjusted by changing the T-shaped hole. The direction can switch the working position of the two-position three-way ball valve 10. The two-position three-way ball valve 10 has a valve stem 11 installed inside. The two-position three-way ball valve 10 has a second air inlet pipe 12 connected to one side of the two-position three-way ball valve 10, and an air guide pipe 13 connected to the first air inlet pipe 9 is connected to the other side of the two-position three-way ball valve 10. The outer side of the top of the feed port 6 is threaded with a sealing cap 14. The sealing cap 14 can seal the feed port 6, and the feed port 6 can be disassembled to add heavy anti-corrosion coating to the inside of the paint tank 3. The top of the base plate 1 is equipped with an electromagnetic heating coil 15 located between the protective sleeve 2 and the paint tank 3. By energizing the electromagnetic heating coil 15, the paint tank 3 can be electromagnetically heated, and the heavy anti-corrosion coating inside the paint tank 3 can be heated at the same time, ensuring that the fluidity of the heavy anti-corrosion coating will not decrease when the equipment is used in a low-temperature environment.

[0020] Among them, the outer side of one end of the second air inlet pipe 12 is connected to a valve 16, and the valve 16 is connected to a high-pressure pipe 17. By opening the valve 16, the high-pressure gas inside the high-pressure pipe 17 can be transported to the paint box 3 or the annular empty pipe 8 through the position switching of the two-position three-way ball valve 10, thereby realizing the transportation of heavy anti-corrosion paint inside the paint box 3 and the cleaning of the inner wall of the nozzle pipe 5.

[0021] An infrared temperature sensor 18 is fixedly installed on the bottom of the inner side of the base plate 1, located below the paint tank 3. The infrared temperature sensor 18 can detect the temperature of the paint tank 3 without affecting the rotation of the paint tank 3. When the temperature of the paint tank 3 reaches the preset value, the power supply of the electromagnetic heating coil 15 can be cut off to ensure that the electromagnetic heating coil 15 will not overheat the heavy anti-corrosion paint inside the paint tank 3.

[0022] When cleaning the inner wall of the nozzle pipe 5, the valve stem 11 is rotated 90 degrees. At this time, the valve core inside the two-position three-way ball valve 10 is in the following state: Figure 4 As shown, the valve core cuts off the connection between the second air inlet pipe 12 and the air inlet 7, and opens the connection between the second air inlet pipe 12 and the air guide pipe 13. The high-pressure gas inside the high-pressure pipe 17 is transported to the interior of the annular empty pipe 8 through the second air inlet pipe 12, the two-position three-way ball valve 10, the air guide pipe 13 and the first air inlet pipe 9. After the high-pressure gas inside the annular empty pipe 8 is discharged through the air outlet, it cleans the paint residue adhering to the inner wall of the nozzle pipe 5. After the inner wall of the nozzle pipe 5 is cleaned, the connection between the high-pressure pipe 17 and the second air inlet pipe 12 is cut off by rotating the valve 16, stopping the transport of high-pressure gas. The valve stem 11 is rotated 90 degrees counterclockwise to reset the valve core inside the two-position three-way ball valve 10, completing the cleaning operation of the inner wall of the nozzle pipe 5.
