Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0020] The utility model will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 As shown: The drug testing filtering device described in this embodiment includes an openable cylinder cover 1 with a semicircular cross-section and a cylinder body 2 combined with the cylinder cover 1 to form a closed space, a filter plate 3 with a semicircular cross-section arranged inside the cylinder body 2 and combined with the cylinder cover 1 to form a conveying cylinder, a rotating shaft 4 arranged at the center of the conveying cylinder, a transmission screw 5 arranged on the rotating shaft 4 and having a radius consistent with that of the conveying cylinder, a feed port 6, a discharge port 7 and a liquid outlet 8 arranged on the cylinder body 2 on one side of the transmission screw 5, and a sealing baffle 10 arranged on the inner side of the conveying cylinder on the other side of the transmission screw 5 and controlled by an adjustment mechanism 9 to move left and right along the rotating shaft 4.

[0021] The drug inspection filtering device described in this embodiment, when in use, first adjusts the position of the sealing baffle 10 according to the amount of material to be filtered, so as to achieve a better filtering effect, and then puts the material from the feed port 6 into the conveying cylinder composed of the filter plate 3 and the cylinder cover 1, and then rotates the rotating shaft 4 forward. At this time, the transmission screw 5 is forwardly transmitted, and the transmission screw 5 continuously transmits the mixed material in the conveying cylinder to the end of the sealing baffle 10. Since the filter plate 3 is set as a semicircular curved surface, the filtering area is larger than that of the flat filter plate 3, thereby improving the filtering effect. When the material reaches the sealing baffle 10, it continues to be transmitted. At this time, the material is squeezed toward the sealing baffle 10, and the moisture in the medicine is squeezed out and falls to the bottom of the cylinder 2 and is discharged from the liquid outlet 8, so that the separation work can be completed well. After the filtration is completed, the rotating shaft 4 is rotated in the opposite direction, and the transmission screw 5 transmits in the opposite direction, pushing the separated material to the right and discharging it from the discharge port 7 to complete the filtration, and the filtration efficiency is high.

[0022] As a further improvement of the above technical solution, the bottom surface of the cylinder 2 is a structure that is inclined downward toward the liquid outlet 8 to facilitate the separation liquid to flow out toward the liquid outlet 8 .

[0023] As a preferred implementation of this embodiment, the cylinder cover 1 is hinged to one side of the cylinder body 2 and fixed by a locking buckle 11 on the other side, so that the cylinder cover 1 can be easily opened or closed like opening and closing a door, thereby facilitating cleaning and maintenance.

[0024] In order to ensure the sealing effect, as a preferred implementation of this embodiment, a sealing strip (not shown in the figure) is provided at the connection between the cylinder cover 1 and the cylinder body 2.

[0025] As a preferred implementation of this embodiment, the adjustment mechanism 9 is any one of a plurality of adjustment screws, hydraulic cylinders, and air cylinders arranged in an array around the rotating shaft 4. The array-arranged structure can ensure the smooth movement of the sealing baffle 10 and avoid tilting and jamming.

[0026] As a further improvement of the above technical solution, a support leg 12 for supporting the ground is provided at the lower end of the cylinder.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
