Description

Technical Field

[0001] This utility model relates to the field of magnetic particle testing, and in particular to a magnetic suspension spraying device, which is mainly used for magnetic particle testing of welds inside large pressure vessels of special equipment. Background Technology

[0002] During the manufacturing and use of pressure vessels for special equipment, defects such as cracks are prone to occur at the weld seams, thus requiring regular non-destructive testing. Magnetic particle testing is a commonly used non-destructive testing method. It involves pre-mixing magnetic powder with water to form a magnetic suspension, which is then sprayed onto the weld surface. The accumulation of magnetic powder at cracks is used to detect weld defects.

[0003] However, the current storage and spraying of magnetic suspension have many shortcomings. Traditional magnetic suspension spraying methods mainly rely on manual operation. Operators need to carry spraying equipment, manually stir the magnetic suspension and manually spray it onto the weld. Manual stirring of magnetic suspension is prone to uneven mixing, which affects the test results; and manual operation is labor-intensive. Summary of the Invention:

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a magnetic suspension spraying device. The magnetic suspension spraying device is reasonably designed and solves the problems of low efficiency, high labor intensity and uneven spraying of traditional manual magnetic suspension spraying, thereby improving the accuracy of detection and work efficiency.

[0005] The present invention relates to a magnetic suspension liquid spraying device, characterized in that it includes a housing, a liquid storage tank mounted on the housing, a stirring pump, a spraying pump, and a nozzle. The liquid storage tank and the stirring pump are connected via a first hose and a second hose. The liquid storage tank is connected to the spraying pump via a third hose. The spraying pump is connected to the nozzle via a fourth hose. A linear guide rail is mounted on the housing, and the nozzle is mounted on the linear guide rail.

[0006] Preferably, the housing is provided with two straps for securing the liquid storage tank, and the two straps are arranged in parallel and spaced apart.

[0007] Preferably, the first hose, the second hose, and the third hose are provided with quick-release connectors.

[0008] Preferably, a T-junction is connected to the fourth hose, one end of which is connected to the spray pump, and the other two ends of the T-junction are connected to the first nozzle and the second nozzle respectively through pipelines.

[0009] Preferably, both the first and second nozzles are mounted on a linear guide rail.

[0010] Preferably, the bottom surface of the housing is equipped with casters and magnets for adsorbing onto the surface of the workpiece to be sprayed with magnetic suspension liquid.

[0011] The working method of this utility model magnetic suspension spraying device is as follows: the storage tank is filled with a mixture of magnetic powder and water, and the stirring pump is started to make the mixture in the storage tank continuously circulate, thereby ensuring that the magnetic powder and water in the mixture do not separate or stratify. In addition, the spraying range of the magnetic suspension can be expanded by installing the nozzle on the linear guide rail.

[0012] Therefore, the magnetic suspension spraying device of this utility model is reasonably designed, overcoming the problems of low efficiency, high labor intensity and uneven spraying of traditional manual magnetic suspension spraying, and can improve the accuracy of detection and work efficiency. Attached image description:

[0013] The present invention will be further described below with reference to the accompanying drawings;

[0014] Figure 1 , 2 This is a three-dimensional structural schematic diagram of the present invention;

[0015] Figure 3 This is a three-dimensional structural diagram of the casing of the removal device of this utility model;

[0016] Figure 4 This is a three-dimensional structural diagram of the bottom of this utility model. Detailed implementation method:

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] This utility model of magnetic suspension spraying device includes a housing 1, a storage tank 2 mounted on the housing 1, a stirring pump 3, a spraying pump 4, and a nozzle 5. The housing 1 can be a rectangular or other shaped shell. The bottom surface of the housing is equipped with casters 14 and magnets 15 for adsorbing onto the surface of the workpiece to be sprayed with magnetic suspension. The magnets 15 can fix the housing relatively on the surface of the workpiece to be sprayed with magnetic suspension. The casters 14 can support the device to propel it against magnetic attraction, thereby moving the device to the target position.

[0019] The storage tank 2 is connected to the stirring pump 3 via a first hose 6 and a second hose 7. The storage tank 2 is connected to the spray pump 4 via a third hose 8. The spray pump 4 is connected to the nozzle 5 via a fourth hose 9. Quick-release connectors 12 are provided on the first hose 6, the second hose 7, and the third hose 8 (i.e., at the middle or end positions). Through these quick-release connectors 12, it is convenient to replace the storage tank 2 filled with magnetic suspension fluid after it is used up, and then connect it via the quick-release connectors 12, so as to achieve the purpose of quick disassembly and assembly of the storage tank 2.

[0020] A linear guide rail 10 is installed on the housing 1, and the nozzle 5 is installed on the linear guide rail 10. Specifically, there may be one or more nozzles 5. The linear guide rail 10 can be moved along its length under control, thereby expanding the range of the magnetic suspension sprayed by the nozzle 5.

[0021] In order to secure the liquid storage tank, the aforementioned housing is provided with two straps 11 for binding the liquid storage tank. The two straps are arranged in parallel and spaced apart. The straps can be elastic straps or buckle straps, etc., and the elastic straps or buckle straps are commercially available components.

[0022] The aforementioned fourth hose 9 is connected to a T-junction 13. One end of the T-junction is connected to the spray pump 4, and the other two ends of the T-junction are respectively connected to the first nozzle 51 and the second nozzle 52 through pipelines. The first nozzle and the second nozzle are both mounted on the linear guide rail 10. The first nozzle 51 and the second nozzle 52 are nozzles of different sizes. The first nozzle 51 can perform fan-shaped spraying and can perform large-area rapid spraying. The second nozzle 52 can perform secondary fine spraying to improve accuracy. The linear guide rail can expand the spraying range of the magnetic suspension liquid and make the nozzle spraying positioning more accurate (the nozzles are all commercially available components).

[0023] The working method of this utility model magnetic suspension spraying device is as follows: the storage tank is filled with a mixture of magnetic powder and water, and the stirring pump is started to make the mixture in the storage tank continuously circulate, thereby ensuring that the magnetic powder and water in the mixture do not separate or stratify. In addition, the spraying range of the magnetic suspension can be expanded by installing the nozzle on the linear guide rail.

[0024] Advantages of this utility model:

[0025] 1. Improve the uniformity of magnetic suspension mixing: The automatic mixing device ensures that the magnetic suspension remains uniformly mixed during the spraying process, avoiding inaccurate detection caused by separation of the magnetic suspension.

[0026] 2. Reduce manual operation: Automated spraying devices reduce manual operation, lower labor intensity, and improve work efficiency.

[0027] 3. Improve magnetic suspension replenishment efficiency: The quick-release connector design enables rapid replacement of magnetic suspension, reducing the time required for equipment to return for replenishment and improving work efficiency.

[0028] 3. Adaptable to complex working environments: The design of magnets and casters enables the device to operate at heights above container walls or in complex environments, expanding the device's applicability.

[0029] 4. Spraying range and spraying accuracy: The design of linear guide rails and graded nozzles of different sizes enables the device to have a larger spraying range and higher spraying accuracy.
