[0006] A reactor body, a stirring motor is arranged on the top of the reactor body, a stirring rod arranged inside the reactor body is arranged on the output shaft of the stirring motor, and a feed port is arranged on the top of the reactor body;

[0007] A discharge pipe is arranged at the bottom of the reactor body, a discharge valve is arranged on the side wall of the discharge pipe, a filter box is arranged at the bottom of the discharge pipe, a pair of filter screens inserted into the filter box body are arranged on the side wall of the filter box from top to bottom, a discharge pipe is arranged at the bottom of the filter box, a reflux pipe inserted into the filter box is arranged on the side wall of the discharge pipe, a reflux valve is arranged on the side wall of the reflux pipe, the reflux pipe is U-shaped, one end of the reflux pipe is placed above the discharge valve and the other end is placed between a pair of filter screens.

[0008] Furthermore, the filter screen plate comprises a grid plate arranged inside the filter box, a filter screen is arranged inside the grid plate, and a sealing plate connected to the grid plate is arranged on the side wall of the filter box.

[0009] Furthermore, a force application groove is provided on the side wall of the sealing plate.

[0010] Furthermore, a guide groove matching the grid plate is provided inside the filter box, a sealing groove matching the sealing plate is provided on the side wall of the filter box, and the sealing groove is communicated with the guide groove.

[0012] Furthermore, a discharge valve is provided on the side wall of the discharge pipe.

[0013] According to the utility model, a discharge filtering structure for a silicone oil reactor is provided. When the uppermost filter screen is clogged, the discharge valve is closed and the reflux valve is opened. The silicone oil enters the filter box along the discharge pipe and the reflux pipe and continues to be filtered and discharged through the lowermost filter screen. Then, the uppermost filter screen is taken out to clean the impurities thereon, thereby facilitating the cleaning. At the same time, since the silicone oil discharge does not need to be stopped during cleaning, the silicone oil discharge filtering operation can continue, thereby improving the discharge filtering efficiency.
