The invention discloses a pipeline port hysteresis buffer demagnetization method and a demagnetizer and relates to the technical field of pipeline systems. Demagnetization coils are wound at a port of a pipeline to be demagnetized; a giant magneto-resistance probe is fixed at an outer edge of the port of the pipeline; the giant magneto-resistance probe is connected with a data interface of a maincontroller of the demagnetizer; and the demagnetization coils are connected with a power output end of the main controller. The method comprises the following steps that: the main controller picks upa signal of the giant magneto-resistance probe and measures the size and direction of the remanence of the pipeline; according to the size and direction of the remanence of the pipeline and differences of materials, the main controller automatically calculates output parameters and controls a circuit part to convert a power frequency alternating current of 50 Hz into a high frequency alternating current of 20 to 45 kHz; and the main controller performs voltage reduction and rectification and controls a power supply to generate the size and direction of a required current so as to obtain a magnetic field of which the size is equal to that of the remanence of the pipeline and the direction is opposite to that of the remanence of the pipeline. Compared with the conventional demagnetization product, the demagnetizer has the advantages of light weight, low energy consumption, advanced control mode, reliability in operation, high demagnetization speed, good demagnetization effect and the like.

The invention discloses a degaussing device for automobile parts, which belongs to the technical field of degaussing devices and includes a frame, a conveying mechanism for automobile parts, a workpiece limiting mechanism, a degaussing machine and a magnetic powder removing mechanism. The workpiece limiting mechanism includes several The limit pressing assembly, the magnetic powder removal mechanism includes a gantry, a vacuum cleaner, a vibration removal assembly, a spray dust suppression assembly and a collection bucket. The frame is provided with a mounting groove, and the input end of the dust collector is connected to the collection bucket. The bottoms are connected by hoses. The beneficial effect of the present invention is that through the magnetic powder removal mechanism, the two vibrating blocks can simultaneously vibrate the two clamped automobile parts below, so that the magnetic powder and dust on the automobile parts can be shaken off, and through the limit The pressing assembly can realize the limit operation of automobile parts of different sizes, so that the automobile parts will not have a large deviation during the process of moving, vibrating or degaussing, and the degaussing efficiency of the automobile parts is improved.

A method for shredding electronic data, involving computer equipment and facilities, the method includes the following steps: Step 1, transmit electronic data according to the user's needs, and select a storage device as a carrier during the transmission process, and the storage device is preferably It is a hard disk; step 2, detect the electronic data in the hard disk, confirm that all the electronic data has been transmitted, and then disconnect the data link; step 3, place the hard disk with the data to be shredded directly under the degaussing device, use the degaussing device to The hard disk of the data is degaussed; step 4, detect the hard disk that has been degaussed in step 3, and detect whether the electronic data exists. If there is residual data, repeat the step 3 again, and the processing can be completed. The electronic data that will be shredded Export it and then crush it, so that not only can the electronic data be crushed, but also the equipment will not be affected. While achieving the purpose of crushing, it can also bring convenience to users.
