[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model provides a large particle interception mechanism and a filtering mechanism to perform secondary filtration on the fluid, thereby improving the filtering effect of the fluid in the reactor pipeline, and playing a role in improving the purity of the reaction materials and the production quality. The fluid in the reactor pipeline first passes through the interception net in the large particle interception mechanism to precipitate large particle crystals, and the small particle crystals or fluid enters the filtering mechanism through the interception net. The fluid is secondary filtered through the filter mesh frame. Under the action of the guide plate, the fluid flow rate can be slowed down, the filtering effect can be improved, and the impact of the fluid on the screw cap can be reduced, thereby improving the purity of the reaction materials and the production quality.

[0013] 2. When the filter mechanism needs to be cleaned, replaced or removed, the screw cap can be loosened to separate the filter mechanism from the guide pipe, thereby fully exposing the filter mechanism for replacement, removal or cleaning. When the storage tray needs to be replaced or removed, the storage tray is snapped into place with the mounting tray, the triangular structure on the storage tray is grasped, the storage tray is rotated to the opening of the mounting tray, and the storage tray is taken out for replacement and removal.

The guide piece 73 is a spiral structure, which guides the flow direction of the fluid, and can slow down the filtering speed, improve the filtering effect, and reduce the impact of the filtered liquid on the rotary cover 71. It also includes a large particle interception mechanism 8, and the large particle interception mechanism 8 includes a mounting plate 81. The mounting plate 81 is arranged on the guide pipe 1, and a storage plate 82 is rotatably connected to the mounting plate 81. The storage plate 82 is detachable and has a triangular structure for easy taking. The storage plate 82 is connected to an interception net 83.

[0021] It should be noted that the reactor pipeline filtering device is used to filter the fluid in the reactor system to ensure the purity of the reaction materials and the production quality, and plays a role in filtering impurities, solid particles or other unnecessary substances. The device is installed under the reactor pipeline, and the fixing bolts 4 are passed through the corresponding mounting holes on the reactor pipeline, and then the fixing nuts 6 are tightened to complete the installation of the device. After the installation is completed, under the action of the anti-stuck spring 5, the fixing nuts 6 can be prevented from loosening during operation vibration, and the fixing nuts 6 can be prevented from getting stuck during the dismantling operation of the device. The fluid is injected into the device, and the fluid first passes through the interception net 83 in the large particle interception mechanism 8 to precipitate large particle crystals, and small particle crystals or fluid pass through the interception net 83 into the filtering mechanism 7, and the fluid passes through the filtering mechanism 7.

The fluid flows into the bottom of the guide pipe 1, and then the solenoid valve 3 is opened, and then discharged through the discharge pipe 2. After the operation is completed, the solenoid valve 3 is closed. When the filter mechanism 7 needs to be cleaned, replaced or removed, the rotary cover 71 can be loosened to make the filter mechanism 7 detach from the guide pipe 1, so that the filter mechanism 7 is fully exposed to facilitate replacement, removal or cleaning operations. When the large particle interception mechanism 8 needs to replace or remove the storage tray 82, the storage tray 82 can be taken out by grabbing the triangular structure on the storage tray 82 and rotating the storage tray 82 to the opening of the mounting tray 81, so as to facilitate faster replacement or removal operations.
