[0028] 3. Beneficial effects:

[0029] By adopting the technical solution provided by the present invention, compared with the prior art, the high-temperature filter sampler with replaceable filter element of the present invention realizes the rapid replacement of the filter element body through the cooperation of the driving member 1, the pressing member and the driving member 2, and facilitates the removal of the filter element body after use, and can realize the rapid sealing operation during the sampling process. The specific contents are as follows:

[0030] When the filter element body needs to be replaced, the motor connected to the bottom of the dial is started to drive the dial to rotate. The dial cooperates with the groove wheel between the groove plate to drive the groove plate and the conversion barrel body on the groove plate to rotate intermittently, so that the unused filter element body inside the conversion barrel body is rotated to between the two telescopic tubes in turn for subsequent sampling work, and the used filter element body in the conversion barrel body is rotated to the access port, so that the filter element body can be quickly replaced;

Then, after the sealing cover is removed, the used filter element body is taken out manually or by a robot, and a new filter element body is placed therein, thereby improving the efficiency of replacement work.

[0032] During the rotation of the guide gear 1, the meshing action of the guide gear 1, the guide gear 2 and the gear ring drives the gear ring to rotate synchronously. When the gear ring rotates, the meshing action of the gear ring and the rack drives the two racks to move relative to each other, thereby driving the two vertical rods and the four driving rods to move relative to each other. The driving rod presses against the sealing ring during the movement. Since the end of the driving rod is arranged in an inclined shape, the upper and lower sealing rings can be driven to move downward and upward respectively. During the downward movement, the sealing ring located at the upper part is pressed tightly against the upper end surface of the filter element body located between the two telescopic tubes to fix the filter element body in the filter element converter. During the displacement process, the upper and lower sealing rings will be synchronously pressed against the upper and lower ends of the conversion barrel to close the space where the filter element body is located between the two telescopic tubes, thereby ensuring that during the sampling process, the sample can be filtered smoothly through the filter element body. Therefore, during the process of replacing the filter cartridge, there is no need to shut down the negative pressure pump and other equipment for a long time, thereby improving work efficiency.
