Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical material screening, and particularly relates to a chemical material screening machine. BACKGROUND

[0002] In the production process of chemical products, in order to ensure the quality of chemical products, the selection of chemical raw materials is strictly controlled. In order to produce high-quality chemical products, the chemical raw materials need to be effectively screened by a vibrating screen, so that good raw materials can be processed and produced.

[0003] According to the search, the Chinese utility model patent with the application number 202020062936.8 discloses a "chemical material screening machine". The reciprocating device drives the movable plate to slide in the chute. The movable plate drives the screening device to move left and right, improving the efficiency of material screening. Meanwhile, the fixed plate and the stirring rod are additionally arranged to stir the material while the screen is shaking, further improving the efficiency of screening and making the screening more sufficient.

[0004] However, the above-mentioned patent has some problems. The movable plate drives the screening device to move left and right, which improves the efficiency of material screening. However, the shaking amplitude of the screening device cannot be controlled. If the shaking amplitude of the screening device is set to be large, there will be an inertial force when shaking. The larger the shaking amplitude, the larger the inertial force. Long-term large-amplitude shaking will reduce the service life of the device. If the shaking amplitude of the screening device is set to be small, when the amount of material is too large and accumulates too much, the upper material will press the lower material, which will cause slow discharging or even unable to discharge.

In this case, a manual adjustment mechanism is needed to increase the shaking amplitude of the screening box driven by the shaking mechanism. At the same time, a stirring mechanism stirs the material in the screening box. The manual adjustment mechanism allows for adjustment of the shaking amplitude at any time, solving the problem mentioned in the background art where if the shaking amplitude of the screening device is set too small, when the amount of material is too large and there is too much accumulation, the excess material at the top presses down on the material at the bottom, leading to slow or even no material discharge. This invention has a simple structure and is highly practical. Attached Figure Description
