Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detectors, in particular to a magnetic particle flaw detector which is easy to recycle. Background Art

[0002] Magnetic particle detectors are commonly used in industrial nondestructive testing. They are mainly used to detect defects such as cracks and pores on the surface or near the surface of ferromagnetic materials. During the flaw detection process, fluorescent magnetic powder is sprayed on the surface of the object to be inspected and the defect location is displayed under the action of the magnetic field. Existing magnetic particle detectors have many shortcomings, so the development of a magnetic particle detector that is easy to recycle is of great practical significance.

[0003] Reference announcement number CN218157695U is a magnetic particle flaw detector that is easy to recycle. It includes a flaw detector body, a spray plate and a collection box. Operating tables are installed on both sides of the flaw detector body, and a baffle is installed on one side of the operating table. A guide plate is installed under the baffle surface, support rods are installed under both ends of the spray plate, and a nozzle is installed under the center of the storage box. The magnetic particle flaw detector that is easy to recycle uses the overall structure of the device to place the items to be inspected in the inspection area, fix and rotate the items through the operating table, and at the same time, the spray plate sprays fluorescent magnetic particles downward. Powder is used to inspect objects. Some of the sprayed fluorescent magnetic powder falls into the collection box for later recovery. The filtered fluorescent magnetic powder falls into the collection box and is pulled out after recovery to facilitate the device to take it out. At the same time, a constant temperature device is installed to heat the inside of the collection tank to prevent the fluorescent magnetic powder from solidifying. Based on the above, although the magnetic particle flaw detector can be well applied, it is usually not convenient to perform double-station sequential inspection on objects, making it difficult for the magnetic particle flaw detector to achieve the expected inspection efficiency for objects, and it needs to be improved.

During the sealing process, the fluorescent magnetic powder liquid will fall through the bottom of the first collecting body 7 into the recovery box 9 on the left for collection. When the rotating driving member 25 drives the baffle 27 to rotate via the rotating shaft 26, the upper end of the baffle 27 abuts against the inner wall on the left side of the first collecting body 7, so that the baffle 27 can guide the fluorescent magnetic powder liquid to the second collecting body 8 and fall into the recovery box 9 on the right for collection. The fluorescent magnetic powder liquid is recovered in a double-station manner, which reduces the waste of the fluorescent magnetic powder liquid and completes the use of the magnetic particle flaw detector.
