Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying equipment, in particular to a nozzle cleaning device for thermal spraying equipment. Background Art

[0002] Thermal spraying is a surface strengthening technology that uses a certain heat source (such as electric arc, plasma spraying or burning flame, etc.) to heat powdered or filamentary metal or non-metallic materials to a molten or semi-molten state, and then uses high-speed airflow to atomize these materials into extremely fine particles and spray them onto the surface of the workpiece at a very high speed to form a coating. The nozzle cleaning device is also called a high-pressure water cleaning machine. The nozzle cleaning device is a cleaning device that uses a high-pressure water column to wash away dirt on the surface of an object. The electric pump completes a water intake and discharge process, and delivers a certain amount of water to the high-pressure pipeline, so that it reaches the high-pressure nozzle with huge energy. However, the diameter of the high-pressure nozzle is much smaller than that of the high-pressure pipeline. Therefore, when the water reaches the high-pressure nozzle, it must be accelerated to flow out of the nozzle hole. It is made of high-quality stainless steel, which is durable and beautiful; it has anti-rust and anti-corrosion functions; it has a simple structure and is flexible and convenient to operate; it is small in size and light in weight (easy to carry); it has a wide range of uses.

[0003] As shown in the application number: CN202222572956.1, the utility model relates to the field of laser cleaning technology, and specifically to a cleaning nozzle bracket structure of a laser cleaning machine, including a main machine, a pipeline is arranged on the side of the main machine, a cleaning head is arranged at one end of the pipeline, a switch block is slidably connected to the side of the cleaning head, a bracket module is arranged on the side of the cleaning head, and the bracket module includes a connecting tube 1 and a connecting tube 2, the inner side surface of the connecting tube 1 is slidably connected to the side surface of the connecting tube 2, and a connecting seat is arranged at one end of the connecting tube 2. In the utility model, the connecting tube 1 is slidably connected to the connecting tube 2, and when cleaning a higher position of the equipment, the positioning rod can be rotated to make the connecting tube 2 extend out of the connecting tube 1. At this time, the cleaning head can be lifted up through the connecting tube 1 and the connecting tube 2 to clean the higher position of the equipment. In this way, there is no need to climb with the help of climbing tools, which is convenient for rapid cleaning of the surface of the equipment.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] The existing device is not pre-treated before cleaning, and since the nozzle contains impurities, cleaning without treatment is a waste of water.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a nozzle cleaning device for thermal spraying equipment is proposed, in order to achieve a more practical purpose. Utility Model Content

[0007] The utility model aims to provide a nozzle cleaning device for thermal spraying equipment to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nozzle cleaning device for thermal spraying equipment, comprising a supporting foot and a swing plate, a cleaning box is provided at the upper end of the supporting foot, and a connecting port is provided on the outer wall of the cleaning box, a swing motor is installed inside the connecting port, and a connecting shaft is installed at the end of the swing motor, the swing plate is arranged at the end of the connecting shaft, and a clamping hole is provided inside the swing plate, a rubber pad is placed inside the clamping hole, and connecting holes are provided on the outer walls at both ends of the swing plate.
