Description

Technical Field

[0001] The utility model relates to a self-detecting permanent magnetic rod, in particular to a magnetic rod with a pneumatic sealing structure. Background Art

[0002] The permanent magnet bar will generate heat during use. If the ambient temperature is too high or the temperature of the permanent magnet bar itself rises, the molecular thermal motion inside the magnet will be enhanced, which will destroy the microstructure of the magnet and disturb the magnetic domain, resulting in a decrease in magnetic force. That is, the magnetic force of the permanent magnet bar will inevitably be insufficient after long-term use, which will lead to a decrease in adsorption capacity. The magnetic force of the permanent magnet bar can be detected by a magnetometer or a gaussmeter. A magnetometer or a gaussmeter is an instrument specially used to measure the magnetic field strength, which can directly measure the magnetic force of the permanent magnet bar. Place the magnetometer or gaussmeter near the permanent magnet bar, and the magnetic force of the permanent magnet bar can be determined according to the reading of the magnetometer. When performing magnetic force detection on ordinary permanent magnet bars, it is only necessary to directly pull the permanent magnet bar out of the stainless steel sleeve when cleaning or repairing the entire iron removal device, which is more convenient. However, for pneumatic self-demagnetizing magnet bars, since their permanent magnets must be sealed between the steel sleeve, it is very inconvenient to disassemble and assemble, and is not suitable for the above method. Utility Model Content

[0003] The utility model aims at the deficiencies in the prior art and provides a magnetic rod that automatically monitors the permanent magnetic force, thereby solving the problem that the pneumatic sealed magnetic rod cannot pull out the magnetic core for magnetic strength detection. By arranging a fixed-point detector on the steel sleeve, when the magnetic core moves, the entire magnetic core can be detected. Moreover, the fixed detector can also monitor the change of strong strength in real time.

[0004] In order to solve the above technical problems, the utility model solves the problems through the following technical solutions: a magnetic rod for automatically monitoring permanent magnetic force, comprising a pneumatic magnetic sleeve and a magnetic core arranged in the pneumatic magnetic sleeve, the pneumatic magnetic sleeve comprising a magnetic section and a non-magnetic section, a front air inlet is arranged between the magnetic section and the non-magnetic section, a rear air inlet is arranged at the bottom of the non-magnetic section, and a magnetic force detection device is arranged on the non-magnetic section near the magnetic section.

[0005] In the above technical solution, preferably, a connecting piece is provided between the magnetic segment and the non-magnetic segment, and the front air inlet is provided on the connecting piece.

[0006] In the above technical solution, preferably, a fixing piece is provided at the bottom of the non-magnetic section, and the rear air inlet is provided on the fixing piece.

[0007] In the above technical solution, preferably, a fixing buckle is provided between the connecting member and the fixing member and in a region close to the connecting member, and the magnetic detection device is provided on the fixing buckle.

[0008] In the above technical solution, preferably, the magnetic detection device includes a magnetometer or a gaussmeter.

[0009] In the above technical solution, preferably, the magnetic detection device is rechargeable.

[0010] The present application is a self-detection device for a pneumatic permanent magnetic rod. The difference between a pneumatic magnetic rod and an ordinary magnetic rod is that the pneumatic magnetic rod uses gas as the power source for moving the magnetic core, which requires the entire magnetic rod to be sealed, while the ordinary magnetic rod uses a cylinder as the power source for the magnetic core, and the magnetic rod structure is open. Therefore, in the magnetic force detection of the magnetic rod, the pneumatic magnetic rod cannot directly pull out the magnetic core for monitoring like an ordinary magnetic rod. For this purpose, the application itself sets a detector on the steel sleeve of the magnetic rod, and the entire magnetic core can be detected by the detector when the magnetic core moves in the steel sleeve.

[0011] Compared with the prior art, the present application solves the problem that the pneumatic sealed magnetic rod cannot pull out the magnetic core for magnetic strength detection. By setting a fixed-point detector on the steel sleeve, the entire magnetic core can be detected when the magnetic core moves. Not only that, the fixed detector can also monitor the changes in strong strength in real time. BRIEF DESCRIPTION OF THE DRAWINGS
