Technical Field

[0001] The utility model relates to the technical field of pesticides, in particular to a screening device for preparing dichlorophenyltriazole. Background Art

[0002] Aryl triazolinone compounds can be used as pharmaceutical or pesticide intermediate compounds.

[0024] The prepared medicine is introduced into the top of the temporary storage box 1. When the medicine contacts the filter plate 3, the impurities therein will be intercepted by the filter plate 3, and the pure medicine will pass through the filter holes of the filter plate 3 and fall into the temporary storage box 1. At the same time, the motor 405 on one side of the mounting frame 2 is started, and the rotating shaft of the motor 405 drives the reciprocating screw 401 to rotate. The moving rod 403, driven by the reciprocating screw 401 and in cooperation with the limiting rod 402, will move back and forth along the direction of the limiting rod 402, and then the push plate 404 will also be driven by the moving rod 403 to move synchronously.
