The data acquisition-based pressure filter feed pump protection device according to claim 7, characterized in that: A plurality of support frames (34) are fixedly mounted on the surface of the fixed frame (26), two springs (35) are symmetrically fixedly mounted inside the support frame (34), a clamping rod (36) is fixedly mounted on one end of the spring (35), and a plurality of clamping blocks (37) are fixedly mounted on the surface of the filter screen (30).

9. The data acquisition-based pressure filter feed pump protection device according to claim 8, characterized in that: The diameter of one end of the clamping block (37) is equal to the inner diameter of the support frame (34), and the diameter of the clamping rod (36) is equal to the inner diameter of the clamping slot on the clamping block (37).

10. A method for using a pressure filter feed pump protection device based on data acquisition according to any one of claims 1 to 9, characterized in that: The following steps are included: S1. Synchronously start multiple guide rails (4) to drive the first protective frame (5) and the second protective frame (6) to move. The first protective frame (5) and the second protective frame (6) move to fit together and cover the feed pump body (2). When the first protective frame (5) and the second protective frame (6) are combined, the first sealing ring (7) and the second sealing ring (8) on the top and side thereof fit around the output end and the input end of the feed pump body (2). The gas detector (10) is used to monitor the air pressure at the connection between the pipes on the output end and the input end and the feed pump body (2) to prevent gas leakage. S2, when the first protection frame (5) and the second protection frame (6) are combined, the two metal sheets (12) on the inner wall thereof are attached to the shaft of the feed pump body (2), and the temperature on the shaft of the feed pump body (2) is conducted by the metal sheet (12), and then the temperature of the feed pump body (2) is monitored in real time by the temperature sensor (13). At the same time, the two support blocks (15) provided inside are also attached to the motor of the feed pump body (2), and the vibration sensor (16) is used to monitor the vibration of the motor. Explosion-proof protection is performed by monitoring the gas leakage, temperature and vibration of the feed pump body (2); S3. When gas leakage, temperature and vibration are abnormal, the gas detector (10), temperature sensor (13) and vibration sensor (16) transmit the monitored data to the first alarm display (17), the second alarm display (18) and the third alarm display (19) respectively to give an alarm. The staff can accurately determine the abnormal point of the feed pump body (2) and take corresponding measures in time to avoid the feed pump body (2) from exploding. S4. Starting the fan (27) can supply air to the interior of the first protective frame (5) and the second protective frame (6), and opening the exhaust valve (29) can discharge the high temperature inside, thereby maintaining a constant temperature inside the first protective frame (5) and the second protective frame (6), and preventing the feed pump body (2) from being wrapped by the first protective frame (5) and the second protective frame (6), resulting in difficulty in discharging the temperature. In addition, during the ventilation process, the filter (30) and the drying block (32) provided on one side of the fixed frame (26) can dehumidify the air, thereby preventing the moisture inside the first protective frame (5) and the second protective frame (6) from affecting the feed pump body (2).
