[0032] According to the above description, the detailed working process of the pipeline demagnetization system provided by the application is as follows:

[0033] Firstly, the 1# magnetic removal device 111 is started, then the 1# material inlet valve 112 and the 1# material outlet valve 113 are opened, when the magnetic removal reaches the preset time, the 2# material inlet valve 122 and the 2# material outlet valve 123 are opened, when the 2# magnetic removal device 121 is started normally, the 1# material inlet valve 112 and the 1# material outlet valve 113 are closed, then the 1# recovery valve 115 and the 1# displacement valve 114 are opened, the non-toxic and inert gas such as nitrogen is passed into the 1# magnetic removal device 111, and when the carbon black raw material gas in the cavity of the 1# magnetic removal device 111 is completely replaced, the 1# recovery valve 115 and the 1# displacement valve 114 are closed, then the magnetic material in the 1# magnetic removal device 111 is allowed to fall, the 1# impurity removal outlet valve 116 is opened, and the impurity removal fan 3 is started, the magnetic material is extracted out of the magnetic removal device by using negative pressure, when the set time is reached, the 1# impurity removal outlet valve 116 is closed, and the impurity removal fan 3 is stopped, when the running period of the 2# magnetic removal device 121 is about to end, the 1# magnetic removal device 111 is started, after the 1# magnetic removal device 111 is started normally, the 2# magnetic removal device 121 performs the operation of stopping and removing the magnetic material, which can be referred to the magnetic removal work of the 1# magnetic removal assembly 11 as described above, and the operation is sequentially and circularly performed.

[0035] It should be noted that the number of the recovery device 2 and the impurity removal fan 3 in the embodiment is one, that is, the two magnetic removal assemblies 1 share one recovery device 2 and one impurity removal fan 3, which reduces the investment in equipment and saves costs. Of course, it is not limited to this, and one recovery device 2 and one impurity removal fan 3 can be respectively arranged for each magnetic removal assembly 1, which is specifically designed according to actual needs.

[0036] In the embodiment, preferably, as shown in Figure 1 That is, the 1# magnetic removal assembly 11 comprises a 1# gas analysis detector 117, and the detection end of the 1# gas analysis detector 117 is in communication with the inside of the 1# magnetic removal device 111, which is used for detecting and analyzing the gas in the 1# magnetic removal device 111, the 2# magnetic removal assembly 12 comprises a 2# gas analysis detector 127, and the detection end of the 2# gas analysis detector 127 is in communication with the inside of the 2# magnetic removal device 121, which is used for detecting and analyzing the gas in the 2# magnetic removal device 121.

[0037] According to the structure described above, when a non-toxic inert gas such as nitrogen is used to replace the carbon black raw gas in the demagnetization device, a gas analyzer can be used to constantly detect whether the replacement is complete, thereby avoiding the discharge of toxic substances into the air.

[0038] In this embodiment, preferably, Figure 1 As shown, the demagnetization devices, namely the 1# demagnetization device 111 and the 2# demagnetization device 121, are both electromagnetic iron removal devices in the prior art. When powered on, they have magnetism and can absorb magnetic substances in the carbon black feed gas, thereby playing a demagnetization role. When the power is turned off, the magnetism disappears, and the magnetism disappears, allowing the absorbed magnetic substances to fall freely and be discharged. Of course, the type of demagnetization device is not limited to the above-mentioned electromagnetic iron removal device, and other types of iron removal devices can also be used, etc., and the specific selection is based on actual needs.

[0043] Further, preferably, the rolling wheels have a self-braking function, so that the support can be automatically stopped when it moves to a designated position. Of course, the rolling wheels can also not have a self-braking function, and a retractable or rotatable support leg is arranged on the support, so that the support leg is in contact with the ground when the support moves to a designated position, so that the rolling wheels are separated from the ground, thereby fixing the support and the de-magnetic device thereon.

[0044] In this embodiment, as shown in Figure 1 the any de-magnetic assembly 1 further comprises a non-toxic inert gas source, and the non-toxic inert gas source is connected to the outlet end of the displacement valve through a pipeline.

[0045] According to the above-described structure, when it is necessary to displace the carbon black raw material gas in the de-magnetic device, the displacement valve and the recovery valve can be opened, and the non-toxic inert gas in the non-toxic inert gas source is introduced into the de-magnetic device.

[0046] In this embodiment, as shown in Figure 1 the recovery device 2 is a gas recovery device, which can effectively recover the carbon black raw material gas, avoid environmental pollution, has low investment and long service life. Of course, the recovery device 2 can also adopt some other tank body, which is selected according to actual needs.

[0047] It should be noted that the communication between the components in this embodiment is achieved through a pipeline, which is a conventional setting and will not be described in detail here.

[0048] In this embodiment, as shown in Figure 1 the displacement valve, the recovery valve, the material inlet valve, the material outlet valve and the impurity removal outlet valve in the two de-magnetic assemblies 1 are all solenoid valves;

[0049] The pipeline de-magnetic system further comprises a controller, and the controller is in communication connection with the 1# displacement valve 114, the 1# recovery valve 115, the 1# recovery device 2, the 1# material inlet valve 112, the 1# material outlet valve 113, the 1# impurity removal outlet valve 116, the 1# gas analysis detector 117, the 1# de-magnetic device 111, the 2# displacement valve 124, the 2# recovery valve 125, the recovery device 2, the 2# material inlet valve 122, the 2# material outlet valve 123, the 2# impurity removal outlet valve 126, the impurity removal fan 3, the 2# gas analysis detector 127 and the 2# de-magnetic device 121, that is, the above-mentioned components contained in the 1# de-magnetic assembly 11 and the 2# de-magnetic assembly 12 are in communication connection with the controller.

[0050] According to the structure described above, the controller can be used to control the opening or closing of each of the above-mentioned components, thereby realizing automatic control. After the equipment has been running for a certain period of time, the inspection personnel only need to replace the filter bag 4 connected to the impurity removal fan 3 described below, which saves time and effort and improves efficiency.

[0051] Furthermore, preferably, the controller can be a Siemens-PIC 200smart controller in the prior art, but is not limited thereto and can be selected according to actual needs.

[0058] Step 6: Detect and analyze the gas in the demagnetization device 111. When it is known that the toxic gas in the demagnetization device has been completely replaced, close the recovery valve 115 and the replacement valve 114.

[0059] Step 7: Open the 1# impurity removal outlet valve 116 and close the 1# demagnetization device 111;

[0060] Step 8: Start the impurity removal fan 3 to blow the magnetic material into the filter bag 4;
