This application relates to an adhesive feeding and screening device, belonging to the technical field of screening equipment. It includes a screening box with a feed inlet at the top and a conical structure at the bottom, and two collection cylinders placed at the bottom of the screening box. A screening plate is hinged inside the screening box. Both collection cylinders are connected to the bottom of the conical structure and communicate with the interior of the screening box. A discharge port is opened along the axis at the bottom end of the conical structure of the screening box. A connecting pipe is connected to the top of collection cylinder one for docking with the discharge port. A discharge annular groove is also formed around the discharge port at the bottom of the screening box. A collection ring frame is fitted onto the connecting pipe, and the bottom end of the collection ring frame communicates with collection cylinder two. A retaining ring is slidably disposed on the connecting pipe between the collection ring frame and the bottom of the screening box to close the discharge annular groove. A stop block assembly for closing the discharge port is slidably disposed inside collection cylinder one. This application improves the structure of the adhesive feeding and screening device, making it easier to collect raw material particles after screening.

The invention discloses a precise regulation and control method and system for a separation process of negentropy small molecule water preparation, and relates to the technical field of water treatment. The method comprises the following steps: performing turbidity detection and judgment on purified small molecule water, determining an initial negentropy separation parameter based on historical data, performing separation operation, calculating a negentropy separation deviation value, and generating a corresponding regulation and control signal in combination with a comparison result of a separation negentropy value and a target negentropy value; and feedback strategies such as temperature and pressure parameter adjustment, separation time increase and decrease or separation stop are adopted according to different regulation and control signals. The system comprises a data acquisition module, a turbidity judgment module, a separation execution module, a parameter calculation module, a signal generation module and a precise regulation and control module, and is used for executing the method. According to the method, the technical problems of large negentropy value fluctuation and overhigh energy consumption in the negentropy small molecule water preparation process are solved, the optimal balance between the separation effect and the energy consumption cost is realized, and the technical scheme can be clearly implemented.
