Description

Technical Field

[0001] This invention relates to the field of filtration equipment technology, specifically a multi-filter head filtration device. Background Technology

[0002] Before entering the instrument (chromatography, spectroscopy, mass spectrometry) for detection, the extract (aqueous solution or organic solution) in the experiment must be filtered through a 0.45 or 0.2 μm filter to remove impurities. Currently, the sampling method is a syringe + filter, and the filtrate is collected by manual squeezing.

[0003] For example, a Chinese patent discloses a "Miniature Syringe-Type Water Analysis Filter" (patent number: CN200920209633.8). This patent includes a syringe, an upper cover plate, a lower cover plate, a porous support plate, and a filter membrane. The upper cover plate, porous support plate, and lower cover plate are arranged sequentially, one above the other. The porous support plate is installed horizontally inside the upper cover plate. The filter membrane is fixed to the surface of the porous support plate. The lower cover plate is installed horizontally inside the upper cover plate and is located below the porous support plate. An inlet and an outlet are respectively located in the middle of the upper and lower cover plates, and the inlet and outlet are on the same vertical axis. The needle hole of the syringe can be securely inserted into the inlet on the upper cover plate. This miniature syringe-type water analysis filter is not only small in size and low in cost, but also space-saving and easy to use, making it more suitable for water analysis sampling.

[0004] However, the aforementioned patent only provides single-layer filtration. Once the filtration effect becomes ineffective, reinstallation and re-filtration are required. This significantly increases the number of manual operations and consequently reduces worker efficiency. Summary of the Invention

[0027] This invention provides a multi-filter head filtration device, such as... Figure 1-7 As shown, the system includes a base mechanism 1, a vertical plate 9, an adjustment mechanism 13, and multiple filter needles 8. The vertical plate 9 has a sliding groove 7 and is mounted on the base mechanism 1. The base mechanism 1 includes a base plate 5, a rotating seat 4, a motor 23, and a support 2. The rotating seat 4 is pivotally connected to the base plate 5, and the support 2 is vertically mounted on the rotating seat 4. The motor 23 is mounted on the support 2. The vertical plate 9 and the adjustment mechanism 13 are both located at the output end of the motor 23. A beaker 3 is mounted on the rotating seat 4. Multiple filter needles 8 are slidably fitted onto the sliding groove 7, and the multiple filter needles 8 are sequentially inserted end-to-end, with each filter needle 8 corresponding to the beaker 3.

[0028] The filter needle 8 includes an upper connector 16, a lower connector 27, a filter screen 33, and a housing 17. The upper connector 16 and the lower connector 27 are respectively located at the top and bottom of the housing 17, and the filter screen 33 is located inside the housing 17. The end of the lower connector 27 away from the housing 17 is pointed.

[0029] The filter needle 8 also includes two mounting brackets 28, a counterweight 29, a plug 34, two arc-shaped retainers 25, and multiple insertion rods 18. The two arc-shaped retainers 25 are detachably snapped onto the front and rear surfaces of the housing 17, and the two plugs 34 are inserted into the sides of the housing 17. The two mounting brackets 28 are mounted on the plugs 34, and one end of each insertion rod 18 is detachably snapped onto the mounting bracket 28, while the other end is detachably snapped onto the arc-shaped retainer 25.

[0030] The filter needle 8 also includes a counterweight 29 and a magnetic block 6. The counterweight 29 is located on the same plane as the lower connecting plug 27 and is mounted on the mounting bracket 28. The magnetic block 6 is slidably fitted in the slide groove 7 and is detachably pivotally connected to the plug 34.

[0031] The bottom of the vertical plate 9 is provided with a mounting plate 24, which is connected to the output end of the motor 23.

[0032] The adjusting mechanism 13 includes a crossbar 26, two mounting plates 11, multiple drive sliders 19, and a connecting seat 20. The crossbar 26 is mounted on the output end of the motor 23, and the two mounting plates 11 are vertically mounted on the crossbar 26. The mounting plates 11 are parallel to the mounting plate 24, and the multiple drive sliders 19 are slidably engaged on the outer side of the mounting plates 11. The connecting seat 20 is mounted on the drive sliders 19.

[0033] The adjustment mechanism 13 also includes an electromagnet 14 and an electric telescopic rod 12. The electric telescopic rod 12 is horizontally mounted on the connecting seat 20, and the electromagnet 14 is mounted on the movable end of the electric telescopic rod 12. The electromagnet 14 corresponds to the magnetic block 6.

[0034] The adjustment mechanism 13 also includes multiple drive telescopic rods 21, multiple rollers 30, multiple U-shaped frames 32, multiple drive motors 31, and a support plate 22. The multiple drive telescopic rods 21 are evenly spaced inside the mounting plate 11, and the support plate 22 is mounted on the movable end of each drive telescopic rod 21. The U-shaped frames 32 are mounted on the support plate 22, the rollers 30 are mounted on the U-shaped frames 32, and the drive motors 31 are mounted on the support plate 22. The drive motors 31 are linked to the rollers 30.

[0035] Working principle: When personnel need to perform multi-level cyclic filtration on samples, firstly, two arc-shaped brackets 25 are installed on the original filter. At the same time, the guide rail groove 15 is restricted by the mounting bracket 28 and the insertion rod 18. Next, the magnetic block 6 is installed on the plug 34, and the motor 23 is controlled to work, making the insertion plate 24 stand upright. Then, the snap-fit ​​plate 10 is opened, and the magnetic block 6 is sent into the slide groove 7. At the same time, under the action of the counterweight 29, the upper connector 16 faces upward and the lower connector 27 faces downward, allowing multiple filter needles 8 to be inserted in sequence. Next, the drive slider 19 is moved so that the electromagnet 14 on it corresponds to the uppermost filter needle 8. Then, the electric telescopic rod 12 extends, bringing the electromagnet 14 closer to the magnetic block 6, thus fixing the electromagnet 14 to the magnetic block 6. Then, the drive slider 19 moves down, causing the multiple filter needles 8 to squeeze and restrict each other. At the same time, the operator puts the beaker 3 onto the rotating seat 4, and then the sample drips in from the highest filter needle 8, passing through layers of filtration and falling into the beaker 3. This completes the purpose of multi-layer filtration.

[0036] When multiple samples need to be filtered, the motor 23 first levels the mounting plate 24. The filter needles 8 automatically adjust under the action of the counterweight 29. Then, the operator sequentially adjusts the positions of the multiple filter needles 8 in the slide groove 7, ensuring that the rollers 30 on the mounting plate 11 contact the guide rail groove 15. Next, multiple electromagnets 14 are controlled to correspond one-to-one with and fix to multiple magnetic blocks 6. The operator then places the beaker 3 sequentially at the bottom of the multiple filter needles 8 for filtration.

[0037] When personnel need to inspect used filter needles 8 to roughly determine whether they need to be replaced, the traditional method of horizontally arranging multiple filter needles 8 presents blind spots due to the long lateral distance, requiring personnel to move around while observing. The traditional method of vertically stacking filter needles 8 requires personnel to remove them from the chute one by one from top to bottom, observe them, and then put them back. This invention, however, allows multiple filter needles 8 to be vertically fixed by electromagnets 14 and magnetic blocks 6, separating them. Then, a drive motor 31 drives rollers 30, causing them to rotate in the guide grooves 15 on each filter needle 8. Since the plug 34 is pivotally connected to the magnetic block 6, the beakers 3 rotate, tilting the upper connectors 16 on the multiple beakers 3. This allows personnel to check the usage status of all filter needles 8 simply by visual observation without moving around, and eliminates the need to remove and put away multiple filter needles 8.

[0038] In summary, this multi-filter head filtration device, through the coordinated arrangement of the base mechanism 1, the vertical plate 9, the adjustment mechanism 13, and multiple filter needles 8, enables the invention to achieve multiple filtration functions by overlapping multiple originally independent filter needles. Furthermore, it can be laid down to filter multiple samples simultaneously, greatly facilitating user operation and improving work efficiency.
