Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a high-efficiency atomizing device for PTFE coating anti-corrosion spraying. Background Technology

[0002] Currently, common high-efficiency atomization devices for PTFE coating anti-corrosion spraying typically include a sprayer body, which is equipped with an air pipe interface for introducing compressed air and a material pipe interface for conveying PTFE coating. The air pipe and material pipe are respectively connected to the corresponding interfaces, and the coating is atomized and sprayed by air pressure or mechanical force.

[0003] However, in actual use, due to the viscosity of PTFE coating, paint residue is easily left at the ends and connecting ports of the air pipe and material pipe after long-term use. It is necessary to disassemble the air pipe and material pipe regularly for cleaning and maintenance. During disassembly and cleaning, the connecting ports at both ends of the sprayer (i.e., the inner connecting parts of the air pipe interface and the material pipe interface) will be directly connected to the external environment. At this time, dust and impurities in the external environment can easily enter the interior of the sprayer through the connecting ports. When the air pipe and material pipe are reinstalled for spraying, the dust that has entered will mix into the PTFE coating, causing impurities to be mixed in the atomized paint particles, which in turn forms defects such as pinholes and protrusions on the coating surface, seriously affecting the uniformity and density of the coating and reducing the anti-corrosion performance of the PTFE coating. Therefore, this utility model proposes a high-efficiency atomization device for anti-corrosion spraying of PTFE coating to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency atomizing device for PTFE coating anti-corrosion spraying, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency atomizing device for PTFE coating anti-corrosion spraying, comprising a sprayer body, wherein the sprayer body is provided with an air pipe interface for introducing compressed air and a material pipe interface for conveying PTFE coating.

[0007] A partition cavity is provided at the air pipe interface and the material pipe interface;

[0008] The spacer cavity is equipped with protective components to prevent dust from entering the air pipe interface and the material pipe interface;

[0009] The protective component includes a structural block with integrally formed spacers at both ends. The spacers at both ends are inserted into the spacer cavity, and the two sets of spacers can provide a sealing function between the air pipe interface, the material pipe interface and the outside.

[0010] Preferably, the upper end of the sprayer body is provided with a limiting part, one end of the limiting part is provided with a plug-in groove, the structural block extends upward with a plug-in block, and the diameter of the plug-in block is adapted to the plug-in groove.

[0011] Preferably, the plug-in block has a rectangular cavity on its end side.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a high-efficiency atomizing device for PTFE coating anti-corrosion spraying, including a sprayer body 1. The sprayer body 1 is provided with an air pipe interface for introducing compressed air and a material pipe interface for conveying PTFE coating. An atomizing nozzle 2 is provided on one side of the sprayer body 1. An interval cavity 4 is provided at the air pipe interface and the material pipe interface. A protective component 5 is provided in the interval cavity 4 to prevent dust from entering the air pipe interface and the material pipe interface. The protective component 5 includes a structural block 51. The two ends of the structural block 51 have integrally formed partition plates 52. The partition plates 52 at both ends are inserted into the interval cavity 4, and the two sets of partition plates 52 can play a role in separating and sealing the air pipe interface, the material pipe interface and the outside.

[0026] The spacer plate 52 in the protective component 5 can seal the air pipe and material pipe interfaces from the outside during disassembly and cleaning, preventing external dust and impurities from entering the sprayer body 1 through the connection port. This prevents impurities from mixing into the PTFE coating, ensuring the purity of the atomized coating particles, reducing defects such as pinholes and protrusions on the coating surface, ensuring the uniformity and density of the coating, and improving the corrosion resistance of the PTFE coating.

[0027] Please see Figures 1 to 4The upper end of the sprayer body 1 is provided with a limiting part 11, and one end of the limiting part 11 is provided with a plug-in groove 111. The structural block 51 extends upward with a plug-in block 53. The diameter of the plug-in block 53 is adapted to the plug-in groove 111. The end side of the plug-in block 53 is provided with a rectangular cavity 531. The protective component 5 also includes a limiting block 55, which is adapted to the rectangular cavity 531. One end of the limiting block 55 is connected to a fixing post 54. The fixing post 54 extends out from one side of the limiting part 11. The extended part of the fixing post 54 is installed on one side of the limiting part 11 by means of a spring 56. The end of the fixing post 54 is provided with a toggle cap 57, which is made of rubber.

[0028] Through the matching design of the plug-in block 53 and the plug-in slot 111, and the limiting structure composed of the limiting block 55, the fixing post 54 and the spring 56, the partition plate 52 can be quickly installed and fixed, and the operation is convenient. At the same time, the rubber toggle cap 57 makes it easy for the operator to operate the fixing post 54 and can enhance the comfort during operation, ensuring the stability of the protective component 5 during use.

[0029] Please see Figures 1 to 4 The outer end of the partition plate 52 is provided with a rubber layer 521, which is attached to the outer end of the partition plate 52 by Velcro.

[0030] When cleaning and maintenance of the air pipe and material pipe are required, first turn off the compressed air source and the PTFE coating delivery system, and remove the air pipe and material pipe from the sprayer body 1. At this time, manually pull the actuating cap 57 outward, which will drive the fixing column 54 to move outward against the elastic force of the spring 56, so that the limiting block 55 exits the insertion groove 111 of the limiting part 11. Align the spacer plates 52 at both ends of the structural block 51 with the spacer cavity 4, and push them horizontally until the insertion block 53 is fully inserted into the insertion groove 111. Release the actuating cap 57, and the spring 56 will rebound and push the fixing column 54 inward, so that the limiting block 55 is locked into the rectangular cavity 531 of the insertion block 53, thus completing the locking of the protective component 5. At this time, the rubber layer 521 of the two sets of spacer plates 52 is tightly attached to the inner wall of the spacer cavity 4, realizing the sealing and isolation of the air pipe interface and material pipe interface from the outside.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
