DETAILED DESCRIPTION

[0018] A solid-phase extraction filtrate device includes a filter bottle 103 and a filter plate I 106 fixedly connected to the bottom of the filter bottle 103. A filter plate II 201 is provided in the filter bottle 103. The front and rear sides of the filter plate II 201 are respectively fixedly connected to a sliding seat 202. The tops of the two sliding seats 202 are respectively slidably connected to two vertical rods 105. The two vertical rods 105 are respectively fixedly connected to the front and rear sides of the outside of the filter bottle 103.

[0019] This part is based on Figure 1-8The working process expressed in the text is: in order to facilitate the upper filter plate with fixed limit adsorbent to be taken out for cleaning at any time, thereby preventing excessive impurities from adhering to the surface of the upper filter plate, when in use, first pour the adsorbent into the filter bottle 103, and seal the adsorbent through the filter plate I 106 located at the bottom of the filter bottle 103, then slide the filter plate II 201 into the filter bottle 103 through two sliding seats 202 using two vertical rods 105 to press the adsorbent tightly, and fix the adsorbent, and then pour the liquid to be solid phase extracted into the filter bottle 103. The bottle 103 is preliminarily screened by the filter plate II 201, and the larger impurities are directly filtered out on the surface of the filter plate II 201. Then, the liquid is passed through the adsorbent for further solid phase extraction to obtain a solid phase extraction filtrate. After obtaining the solid phase extraction filtrate, the filter plate II 201 used for preliminarily filtering the above liquid can be taken out and cleaned by the staff to facilitate the next extraction work and extend the service life. The upper filter plate with a fixed limiting adsorbent can be taken out for cleaning at any time, thereby preventing excessive impurities from adhering to the surface of the upper filter plate.

[0020] The surfaces of the two vertical rods 105 are polished.

[0021] The lower side of the filter bottle 103 is fixedly connected to a limiting ring 104 , and the bottom of the filter bottle 103 is rotatably connected to the middle of the upper side of the support frame 101 through the limiting ring 104 .

[0022] The front side of the support frame 101 is fixedly connected to a rotating platform 107, and a rotating rod 304 is rotatably connected to the rotating platform 107. The middle part of the rotating rod 304 is fixedly connected to a pulley II 303. The lower side of the filter bottle 103 is fixedly connected to a pulley I 301, and the pulley II 303 and the pulley I 301 are connected for transmission via a belt 302.

[0023] The pulley II 303 and the pulley I 301 are on the same horizontal plane.

[0024] The top of the rotating rod 304 is fixedly connected to a rotating plate 305 , and the outer side of the rotating plate 305 is fixedly connected to a handle.

[0025] This part is based on Figure 1-8The working process expressed in the figure is: in order to accelerate the flow efficiency of the filtrate through the adsorbent between the filter plate I 106 and the filter plate II 201, thereby effectively accelerating the overall solid phase extraction process, when in use, the operator grasps the handle located on the outside of the rotating plate 305, so that the handle on the outside of the rotating plate 305 performs a circular motion, and the center of the circular motion is the rotating rod 304, and then the rotating rod 304 rotates on the rotating table 107. When the rotating rod 304 rotates, the belt 302 drives the pulley II 303 and the belt The wheel I301 rotates synchronously, and then the pulley I301 located at the rear side drives the filter bottle 103 to rotate in the middle of the upper side of the support frame 101 by relying on the limit ring 104, so that the liquid inside the filter bottle 103 rotates synchronously to generate a certain centrifugal force, thereby quickly passing through the adsorbent and flowing out the solid phase extraction filtrate from the bottom filter plate I106, which facilitates the acceleration of the flow efficiency of the filtrate through the adsorbent located between the filter plate I106 and the filter plate II201, thereby effectively accelerating the overall solid phase extraction process, and the result is simple and easy to use.

[0026] A long frame 102 is provided on the right side of the bottom of the support frame 101 , and a collecting container 401 is provided in the long frame 102 .

[0027] The outer side of the collecting container 401 can be attached to the inner side of the long frame 102 for sliding.

[0028] The collecting container 401 is made of glass or metal.

[0029] This part is based on Figure 1-8 The working process expressed therein is: when collecting the filtrate flowing out from the bottom filter plate I 106, the collecting vessel 401 is inserted into the long frame 102 and can be moved horizontally according to the trajectory of the long frame 102, and the collecting vessel 401 is slid to the left side of the long frame 102, that is, the bottom of the filter bottle 103, to collect the solid phase extraction filtrate. Thereafter, the collecting vessel 401 can slide out to the right through the long frame 102 into the support frame 101, and then the staff can take out the collecting vessel 401 straight up and down, without having to take out the collecting vessel 401 obliquely from the bottom of the support frame 101.
