DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-6 The crystal filtration device shown in the figure is used to extract gibberellic acid, including a filtration bottle 1, a side port 2 on the filtration bottle 1 connected to a vacuum pump through a rubber tube, and the Büchner funnel 3 is inserted into the top of the filtration bottle 1 through a stopper 4 installed on the Büchner funnel 3, and the filtration bottle 1 and the Büchner funnel 3 are in a sealed state through the stopper 4; through the auxiliary device 6 provided on the filter screen 5, after completing the filtration task, the filter paper on the filter screen 5 can be quickly taken away, which is convenient and quick compared to the existing inverted Büchner funnel 3 and the use of a drainage rod, and the connection relationship between the auxiliary device 6 and the filter screen is such that the filter screen 5 can also be taken out of the Büchner funnel 3 through the auxiliary device 6 when cleaning is needed.

[0024] In order to facilitate the cleaning of the filter screen 5, in this embodiment, the filter screen 5 in the Büchner funnel 3 is designed to be separated from it, so that after the filtration task is completed, it can be fully cleaned to avoid omissions caused by dead corners. At the same time, after the separation, in order to make the filter screen 5 stably placed on the Büchner funnel 3, four groups of blocks 31 arranged in a circular array are provided on the inner wall of the Büchner funnel 3, and a card groove 51 adapted to the card block 31 is provided on the bottom surface of the filter screen 5, thereby realizing the card position assembly between the two.

[0025] Auxiliary device 6: A cross-shaped placement groove 52 is provided on the top surface of the filter screen 5, and the connecting piece 61 is also cross-shaped, but its specifications are smaller than the placement groove 52, and an insertion rod is provided on the middle bottom surface of the connecting piece 61, and a socket that matches the insertion rod is provided on the placement groove 52. The insertion rod is inserted into the socket to complete the assembly of the connecting piece 61 and the filter screen 5. Through the above-mentioned structural cooperation, the connecting piece 61 can be rotated at a certain angle in the placement groove 52, and a limit block 65 is provided on the outer wall of the outward end of the connecting piece 61, and a limit groove 53 that matches the limit block 65 is provided on the inner wall of the placement groove 52 (close to the inner wall of the Buchner funnel 3). When the above-mentioned connecting piece 61 rotates, the limit block 65 is inserted into the limit groove 53. In this process, the above-mentioned block 31 and the slot 51 limit the filter screen 5. Then, the entire filter screen 5 together with the filter paper and the auxiliary device 6 can be taken out conveniently and quickly through the vertical rod 62 provided at the end of the connecting piece 61.

[0026] In order to prevent the vertical rods 62 from turning inward during use, a T-shaped vertical plate 63 is provided on the top of each group of vertical rods 62 to hang the above structure on the Büchner funnel 3, and the four groups of vertical plates 63 are connected in sequence by a reinforcing ring 64 to achieve the purpose of enhancing the structural strength.

[0027] The working principle of this utility model is as follows: through the stopper 4 on the Buchner funnel 3, it is inserted into the inlet of the suction filtration bottle 1, and then the side port 2 and the vacuum pump are connected through a rubber tube, the filter paper is placed on the filter screen 5, and then the filter paper is soaked with distilled water to prevent the filter paper from warping, and then the workpiece is placed on the filter paper, and then the vacuum pump is turned on for suction filtration;

[0028] After the filtration task is completed, by grabbing the reinforcing ring 64 or the vertical plate 63, the connecting member 61 is driven upward through the vertical rod 62, so that the filter paper above the connecting member 61 is taken out, and then the objects on the filter paper are collected;

[0029] When the entire filtration task is completed and the tool needs to be cleaned, the insertion rod on the connecting piece 61 is inserted into the socket of the placement slot 52, and then the connecting piece 61 is rotated. With the cooperation of the card slot 51 and the card block 31, the filter screen 5 is limited so that the limiting block 65 on the connecting piece 61 is inserted into the limiting slot 53. After completing the limiting connection, pull it up again to bring out the filter screen 5 for separate cleaning.

[0030] The electromechanical connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belongs to common knowledge.

[0031] Components not described in detail herein are prior art.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
