The vacuum pump is connected to the main pipe 4 through the connecting pipe 1. Usually, the vacuum pump can be set outdoors to reduce the influence of the vibration and noise of the vacuum pump on the detection work. The main pipe 4 is connected to a plurality of branch pipes 5. The branch pipes 5 adopt rubber hoses, which are convenient for connection with the suction bottle 2. Each branch pipe 5 is provided with a manual valve 51. The opening and closing of the corresponding manual valve 51 can be selected according to the number of suction bottles 2 used each time. Each branch pipe 5 is connected to a suction bottle 2. A suction bottle placement platform 31 is provided on the table 3. A suction bottle clamping mechanism 6 for clamping the suction bottle 2 is also provided on the table 3.

[0020] The suction bottle clamping mechanism 6 includes a fixed top block 61, a movable top block 62, a mounting plate 63, a guide rod 64, a spring 65, a top plate 66 and a driving assembly 67. The fixed top block 61 is fixed on the suction bottle placement platform 31. The fixed top block 61 is provided with a plurality of fixed top blocks. The mounting plate 63 is provided with a movable top block 62 that cooperates with the fixed top block 61. The mounting plate 63 can be slidably mounted on the suction bottle placement platform 31. A plurality of guide rods 64 are evenly fixed on the mounting plate 63. The guide rods 64 pass through the top plate 66. The top plate 66 is fixed on the suction bottle placement platform 31, and the driving component 67 is used to drive the mounting plate 63 to move on the suction bottle placement platform 31, so that the movable top block 62 clamps the suction bottle 2 placed between it and the fixed top block 61 under the elastic force of the spring 65. The function of the driving component 67 is to move the mounting plate 63 backward to compress the spring 65. When the suction bottle 2 is placed between the fixed top block 61 and the movable top block 62, the movable top block 62 cooperates with the fixed top block 61 under the elastic force of the spring 65 to clamp the suction bottle 2;

[0021] Specifically, the driving assembly 67 includes a support plate 671, a screw rod 672, a sliding block 673, and a crank 674. The front end of the screw rod 672 is rotatably connected to the support plate 671, the screw rod 672 passes through the mounting plate 63 and the top plate 66, the screw rod 672 is rotatably connected to the top plate 66, the rear end of the wheel screw rod 672 is connected to the crank 674, the sliding block 673 is slidably arranged on the suction bottle placement platform 31 on the side of the mounting plate 63 close to the movable top block 62, the screw rod 672 passes through the sliding block 673, and the sliding block 673 is provided with a thread that cooperates with the screw rod 672. When the suction bottle 2 needs to be placed on the suction bottle placement platform 31, the screw rod 672 and the support plate 6 71. The top plate 66 is rotatably connected, and the sliding block 673 is set on the thread matching the screw rod 672 and can be slidably set on the suction filtration platform. The screw rod 672 is rotated by shaking the crank handle 674 to make the sliding block 673 move toward the top plate 66, and the sliding block 673 drives the mounting plate 63 to move, compressing the spring 65. When the space between the fixed top block 61 and the movable top block 62 is enough to put the suction filtration bottle 2, the rotation is stopped, and the suction filtration bottle 2 is put in. Then, the crank handle 674 is rotated to make the sliding block 673 move toward the support plate 671, and the movable top block 62 moves toward the suction filtration bottle 2, until the movable top block 62 and the fixed top block 61 clamp the suction filtration bottle 2 under the elastic force of the spring 65, and the rotation is stopped;

[0022] Preferably, the fixed top block 61 and the movable top block 62 are both rubber blocks shaped like the outer periphery of the bottom of the suction filtration bottle 2;

[0023] Preferably, one end of the branch pipe 5 connected to the suction bottle 2 is connected with a connector 7, and the connector 7 includes a hard insert tube 71 and a rubber plug 72.

The use of the above-mentioned connector 7 can improve the efficiency of connecting the suction bottle 2 with the filtration equipment. When connecting, just insert the connecting pipe of the suction bottle 2 into the rubber plug 72 for connection.

[0024] Working principle: When in use, first rotate the crank handle 674 to move the mounting plate 63 with the moving top block 62 to move the compression spring 65. When the space between the moving top block 62 and the fixed top block 61 is sufficient to place the filter, stop rotating, place the filter bottle 2 on the filter bottle placement platform 31 between the fixed top block 61 and the moving top block 62, then rotate the crank handle 674, and the sliding block 673 moves toward the support plate 671. Under the action of the elastic force of the spring 65, the mounting plate 63 also moves toward the fixed top block 61 until the moving top block 62 and the fixed top block 61 clamp the filter bottle 2. Stop rotating the crank handle 674, and then the staff holds the connecting head 7, the branch pipe 5 and the connecting head 7 are in a normally connected state, and the rubber plug 72 of the connecting head 7 is plugged into the connecting pipe of the filter bottle 2. According to the number of filter bottles 2 used, open the manual valve 51 on the corresponding branch pipe 5, and finally start the vacuum pump to perform the filtration action.
