Description

Technical Field

[0001] The utility model belongs to the technical field of sample filtering, in particular to a high-efficiency filtering device. Background Art

[0002] Filtration is an operation in which the liquid (or gas) in a suspension (or heated gas containing solid particles) passes through a medium under the action of a driving force or other external force, and the solid particles and other substances are retained by the filter medium, thereby separating the solids and other substances from the liquid (or gas).

[0003] The filtration devices currently on the market have difficulty filtering water samples with high suspended matter content. At the same time, the separate suction and filtration filtration devices increase the possibility of pressure leakage, resulting in low filtration efficiency and even clogging of the filter holes. The clogging of the filter holes requires the replacement of the filter membrane. Utility Model Content

[0007] Furthermore, the threads on the first clamping plate and the second clamping plate are arranged in opposite directions, the mouth of the first bottle body is in close contact with the mouth of the second bottle body, and when the threaded rod rotates, the first clamping plate and the second clamping plate will move closer or farther away, and the sample in the second bottle body will enter the second bottle body after being filtered by the metal filter membrane.

[0008] Furthermore, the first clamping plate and the second clamping plate are in close contact with the second bottle body and the bottle mouth of the first bottle body in the initial state. The cooperation between the first clamping plate and the second clamping plate can make the second bottle body in close contact with the bottle mouth of the first bottle body to prevent pressure leakage.

[0009] Furthermore, the airbag is located at the inner bottom of the first clamping plate, and the airbag is in an expanded state in the initial state. When the first clamping plate and the second clamping plate cooperate to clamp the airbag, the airbag will be squeezed by the bottle mouth of the second bottle body. At this time, the air pressure in the airbag will enter the air pressure chamber to cause the piston rod to move to the right.

[0010] Furthermore, in the initial state, the push block is close to the inner side wall of the connecting frame, the opening size of the card slot is equal to the opening size of the groove, and the push block moves to the right and contacts the inner side wall of the connecting frame.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a suction filter nozzle, which can form a negative pressure in the first bottle body through the suction filter nozzle during the filtration process, so that the sample in the second bottle body is accelerated to be filtered through the metal filter membrane. At the same time, the first clamping plate and the second clamping plate cooperate to clamp the bottle mouths of the first bottle body and the second bottle body, thereby reducing the possibility of pressure leakage.

[0014] 2. The utility model is provided with an anti-over-clamping mechanism, so that when the first clamping plate and the second clamping plate cooperate to clamp the bottle mouths of the first bottle body and the second bottle body, the arc block will automatically be clamped into the groove, so that the first clamping plate can no longer move downward, thereby preventing excessive clamping from causing damage to the bottle mouths of the first bottle body and the second bottle body.

[0026] The threads on the first clamping plate 8 and the second clamping plate 9 are arranged in opposite directions, and the mouth of the first bottle body 1 is in close contact with the mouth of the second bottle body 2. When the threaded rod 7 rotates, the first clamping plate 8 and the second clamping plate 9 will move closer to or away from each other, and the sample in the second bottle body 2 will enter the second bottle body 2 after being filtered by the metal filter membrane 4.

[0027] The first clamping plate 8 and the second clamping plate 9 are in close contact with the second bottle body 2 and the bottle mouth of the first bottle body 1 in the initial state. The cooperation between the first clamping plate 8 and the second clamping plate 9 can make the second bottle body 2 and the bottle mouth of the first bottle body 1 in close contact to prevent pressure leakage.

[0028] The airbag 102 is located at the inner bottom of the first clamping plate 8, and the airbag 102 is in an expanded state in the initial state. When the first clamping plate 8 and the second clamping plate 9 cooperate to clamp the airbag 102, the airbag 102 will be squeezed by the bottle mouth of the second bottle body 2. At this time, the air pressure in the airbag 102 will enter the air pressure chamber 101 to make the piston rod 103 move to the right.

[0029] In the initial state, the push block 104 is close to the inner wall of the connecting frame 5 , the opening size of the slot 108 is equal to the opening size of the groove 105 , and the push block 104 moves to the right and contacts the inner wall of the connecting frame 5 .

[0030] The depth of the groove 105 is greater than the length of the arc block 107 . The arc surface of the arc block 107 faces upwards. The arc block 107 can be completely retracted into the groove 105 . When the arc surface of the arc block 107 is squeezed, it will move into the groove 105 .

[0031] A specific application of this embodiment is: docking the second bottle body 2 with the bottle mouth of the first bottle body 1, so that the first clamping plate 8 and the second clamping plate 9 are close to the bottle mouths of the second bottle body 2 and the first bottle body 1 respectively, and rotating the threaded rod 7 to make the first clamping plate 8 and the second clamping plate 9 move close to each other. The cooperation of the first clamping plate 8 and the second clamping plate 9 can clamp the bottle mouths of the second bottle body 2 and the first bottle body 1 to prevent pressure leakage.

When the threaded rod 7 is rotated to make the first clamping plate 8 and the second clamping plate 9 move close to each other, the air bag 102 will be squeezed with the bottle mouth of the second bottle body 2. At this time, the air pressure in the air bag 102 will enter the air pressure chamber 101 to make the piston rod 103 move to the right. , the piston rod 103 moves to the right and drives the push block 104 to contact the inner side wall of the connecting frame 5. At this time, the arc block 107 will be stuck in the slot 108 so that the first clamping plate 8 can no longer move downward, preventing the second bottle body 2 and the first bottle body 1 from being excessively clamped and damaged. When the threaded rod 7 is subsequently reversed to make the first clamping plate 8 and the second clamping plate 9 move away from each other, the arc block 107 will be squeezed by the top of the slot 108 at the beginning and will shrink into the groove 105. The telescopic spring 106 is tightened and will not affect the upward movement of the first clamping plate 8. Subsequently, the air bag 102 leaves the bottle mouth of the second bottle body 2 and gradually rebounds, and the air pressure returns to the air bag 102. At this time, the air pressure in the air pressure chamber 101 drives the piston rod 103 to move to the left to restore, and the push block 104 moves to the left to leave the inner side wall of the connecting frame 5. Finally, the telescopic spring 106 rebounds and drives the arc block 107 to restore.
