Meanwhile, the up-and-down reciprocating movement of the transmission rod 4 can continuously press the inclined surface of the inclined table 31 through the roller 26, when the transmission rod 4 moves upwards, the roller 26 rolls and presses the inclined table 31 and forces the baffle plate 28 to move towards the discharge hole of the feed hopper 38 through the connecting rod 29 (the second spring 30 is compressed) so as to complete temporary blocking of the discharge hole, and when the transmission rod 4 moves downwards, the rolling pressing force of the roller 26 on the inclined table 31 is gradually reduced, the elastic force of the second spring 30 is released to push the inclined table 31, the connecting rod 29 and the baffle plate 28 to return to the initial position, and the blocking of the discharge hole is released. Therefore, the amount of the activated carbon particles conveyed to the sieve plate 2 per unit time is controlled, and the blockage of the sieve is further avoided.
It is worth integratively, when transfer line 4 did not move in this embodiment, striker plate 28 did not block up the discharge gate, and sieve 2 is in the horizontality, and scraper blade 7 does not contact the bottom of screen cloth 8 to the activated carbon particle of discharge gate is accepted to sieve 2.
And when the transmission rod 4 moves upwards, the material blocking plate 28 gradually blocks the material outlet, the sieve plate 2 is in a gradually inclined and upward state, and the scraper 7 gradually scrapes the bottom of the sieve mesh 8 forwards so as to perform timely screening treatment on the activated carbon particles falling onto the scraper 7 in unit time.
And when transfer line 4 downstream, striker plate 28 breaks away from the discharge gate gradually, and sieve 2 is in the downward state of slope gradually, and scraper blade 7 is gradually back to scrape the bottom of screen cloth 8 to the active carbon particle of sieving to the screen cloth 8 bottom is in time scraped to barrel 1 bottom and is gathered.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
