Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology and is a multi-channel high-efficiency filtration booster. Background Technology

[0002] In the fields of environmental monitoring, microbial detection, and laboratory sample pretreatment, syringe filters are widely used due to their simple structure and low cost. A syringe filter typically consists of a medical syringe and a disposable filter head (pore size 0.22-0.45μm). Operation requires manual, continuous pressing of the syringe plunger to force liquid through the filter membrane. However, traditional manual operation has some limitations. For example, filtering high-viscosity samples requires significant pressure and strong hand strength from the operator, and the operator cannot process multiple samples simultaneously, resulting in low efficiency. Summary of the Invention

[0003] This invention provides a multi-channel high-efficiency filter booster that overcomes the shortcomings of the prior art and can effectively solve the problems of low filtration efficiency and easy fatigue of existing needle filters.

[0004] The technical solution of this utility model is achieved through the following measures: A multi-channel high-efficiency filter booster includes a scissor jack, a fixed frame, a mounting base, a push plate, and support columns. The bottom plate of the scissor jack has a through notch, and the fixed frame is fixedly installed inside the notch. The mounting base is detachably fixedly installed on the lower side of the fixed frame. The upper side of the mounting base has at least one through mounting hole at intervals. A push plate is provided between the lower part of the scissor jack screw and the upper part of the fixed frame. Several support columns are evenly distributed on the upper side of the push plate corresponding to the front and rear positions of the scissor jack screw. The upper end of each support column is fixedly installed together with the corresponding position on the lower side of the top seat of the scissor jack.

[0005] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution: The lower side of the aforementioned push plate may have six downward-facing circular grooves evenly distributed at intervals.

[0006] The upper side of the aforementioned card holder may have two to six through mounting holes spaced at intervals, which can correspond vertically to the circular groove.

[0007] The aforementioned mounting holes may include a first limiting hole and a second limiting hole, with the lower part of the first limiting hole and the upper part of the second limiting hole communicating with each other. The cross-section of the first limiting hole matches the flange at the upper end of the syringe, and the second limiting hole matches the outer side of the lower end of the syringe.

[0008] The upper left and upper right sides of the aforementioned card holder may each have several threaded holes distributed at intervals. The upper side of the fixing frame corresponding to each threaded hole position is provided with a connecting through hole, and each connecting through hole is provided with a bolt that is screwed into the corresponding threaded hole on the lower outer side.

[0009] The push plate at the front and rear positions of the screw of the aforementioned scissor jack can each have two supports evenly spaced on the left and right, and each support has a scale mark on its outer side.

[0010] This utility model has a reasonable and compact structure. In use, the mounting base is disassembled from the fixing frame, and then the water sample is drawn into a conventional syringe filter. The syringe filter includes a syringe barrel, a flange surrounding the syringe barrel, a piston rod inserted into the syringe barrel, and a pressing plate connected to one end of the piston rod. A disposable filter head is connected to the lower end of the syringe barrel. During filtration, the operator pulls the piston rod to draw the water sample into the syringe barrel, then inserts the disposable filter head into the lower end of the syringe barrel. Finally, pressure is applied to the pressing plate to push the piston rod, thus completing the filtration. When a large amount of water sample needs to be filtered using a syringe filter, the scissor jack can save effort and reduce labor intensity. The mounting base can install multiple syringe filters, and the pressing plate can simultaneously push the pressing plate, allowing multiple syringe filters to be filtered at the same time. This improves filtration efficiency and ensures that the pressing speed of the pressing plate is consistent and uniform. Attached Figure Description

Detailed Implementation

[0021] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0022] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 As shown, the multi-channel high-efficiency filter booster includes a scissor jack 1, a fixed frame 2, a mounting base 3, a push plate 4, and support columns 5. The base plate 6 of the scissor jack 1 has a through notch, and the fixed frame 2 is fixedly installed in the notch. The mounting base 3 is detachably fixedly installed on the lower side of the fixed frame 2. The upper side of the mounting base 3 has at least one through mounting hole at intervals. The push plate 4 is located between the lower part of the screw 7 of the scissor jack 1 and the upper part of the fixed frame 2. Several support columns 5 are evenly distributed on the upper side of the push plate 4 corresponding to the front and rear positions of the screw 7 of the scissor jack 1. The upper end of each support column 5 is fixedly installed together with the corresponding position on the lower side of the top seat 9 of the scissor jack 1.

[0024] According to the requirements, the scissor jack 1 is a known technology. The scissor jack 1 includes a base plate 6, a screw 7, a hinge shaft 8, and a top seat 9. Lower support arms are hinged to both sides of the base plate 6, and upper support arms are hinged to both sides of the top seat 9. The upper side of the lower support arm and the lower side of the upper support arm are hinged together by the hinge shaft 8. The right hinge shaft 8 has a threaded through hole, and the right part of the screw 7 is screwed into the threaded through hole. The right side of the left hinge shaft 8 has a rotating groove, and the left end of the screw 7 is rotatably installed in the rotating groove. A handle is installed on the right end of the screw 7, which can save effort when rotating the screw 7. The length of the handle can be extended according to the requirements (such as by screwing on the two ends of the handle).

[0025] In use, the card holder 3 is separated from the fixing frame 2, and then the water sample is drawn into the existing known syringe filter. The syringe filter includes a syringe 10, a flange 11 located on the outer side of the upper end of the syringe 10, a piston rod 12 inserted into the lower part of the syringe 10, and a pressing plate 13 connected to the upper end of the piston rod 12. The lower end of the syringe 10 is connected to a disposable filter head 14. During filtration, the operator pulls the piston rod 12 to draw the water sample into the syringe 10. Then, a disposable filter head 14 is inserted into the lower end of the syringe 10. Finally, the piston rod 12 is pushed by applying pressure to the pressing plate 13, thereby completing the filtration of the water sample in the syringe 10. When a large amount of water sample needs to be filtered using a syringe filter, the scissor jack 1 can save effort and reduce labor intensity. The mounting base 3 can install multiple syringe filters, and the pressure plate can push the pressing plate 13 at the same time, enabling multiple syringe filters to be filtered simultaneously. This not only improves filtration efficiency but also ensures that the pressing speed of the pressing plate 13 is consistent and uniform.

[0026] The above-mentioned multi-channel high-efficiency filter booster can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown, the push plate 4 has six downward-facing circular grooves 15 evenly distributed on its lower side.

[0027] During use, the circular groove 15 can limit the pressure plate 13 of the needle filter installed in the mounting hole. The pressure plate 13 of the needle filter is located in the circular groove 15. After rotating the handle of the scissor jack 1, the push plate 4 moves downward under the action of the scissor jack 1. The push plate 4 pushes the pressure plate 13 of the needle filter, and pushes the piston rod 12 by applying pressure to the pressure plate 13, thereby completing the filtration of the water sample.

[0028] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3As shown in Figures 9 to 9, the upper side of the card holder 3 is provided with two to six through mounting holes at intervals, which can correspond vertically to the circular groove 15.

[0029] Depending on the requirements, the upper side of the mounting base 3 is provided with two, four, or six vertically penetrating mounting holes spaced at intervals. The front mounting holes and the rear mounting holes are symmetrically distributed about the central axis of the screw 7 of the scissor jack 1. When the upper side of the mounting base 3 is provided with two vertically penetrating mounting holes spaced at intervals, the mounting holes correspond one-to-one with the two circular grooves 15 in the middle. When the upper side of the mounting base 3 is provided with four vertically penetrating mounting holes spaced at intervals, the mounting holes correspond one-to-one with the four circular grooves 15 in the middle. When the upper side of the mounting base 3 is provided with six vertically penetrating mounting holes spaced at intervals, the mounting holes correspond one-to-one with the six circular grooves 15.

[0030] The mounting hole is used to limit the syringe 10 of the syringe filter. The push plate 4 pushes the press plate 13 of the syringe filter. The press plate 13 applies pressure to the piston rod 12. After the piston rod 12 moves downward, it pushes the water sample in the syringe 10 into the disposable filter head 14 to complete the filtration.

[0031] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown in Figure 9, the mounting hole includes a first limiting hole 16 and a second limiting hole 17. The lower part of the first limiting hole 16 and the upper part of the second limiting hole 17 are interconnected. The cross-section of the first limiting hole 16 matches the flange 11 at the upper end of the syringe 10, and the second limiting hole 17 matches the outer side of the lower end of the syringe 10.

[0032] According to the requirements, the cross section of the first limiting hole 16 and the outer flange 11 of the upper end of the injection cylinder 10 are both elliptical, and the second limiting hole 17 and the lower part of the injection cylinder 10 are both circular. The second limiting hole 17 is used to hold the injection cylinder 10, and the first limiting hole 16 is used to embed the outer flange 11 of the upper end of the injection cylinder 10. This facilitates the installation between the needle filter and the holder 3 and avoids the needle filter from tilting or rotating during use.

[0033] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown in Figure 9, the upper left and upper right sides of the card holder 3 are provided with a number of threaded holes at intervals. The upper side of the fixing frame 2 corresponding to each threaded hole position is provided with a connecting through hole. Each connecting through hole is provided with a bolt 18 that is screwed into the threaded hole at the corresponding position on the lower outer side.

[0034] According to the requirements, the upper left and upper right sides of the fixed frame 2 are each spaced apart with six connecting through holes, and the total number of connecting through holes is twelve. The three connecting through holes at the front and the three connecting through holes at the rear are symmetrically distributed about the central axis of the screw 7 of the scissor jack 1. The upper left and upper right sides of the card holder 3 are each spaced apart with two threaded holes. The four threaded holes on the upper side of the card holder 3 are located at the four corners of the card holder 3. The bolt 18 is a known hand-tightening screw.

[0035] When the card holder 3 has two mounting holes spaced at the front and back on the upper side, it is used to install two needle-type filters. After passing through the four connecting through holes on the inner side, four bolts 18 are screwed into the threaded holes at the four corners on the upper side of the card holder 3 respectively. In this way, the card holder 3 with two needle-type filters can be detachably and fixedly installed together with the fixing frame 2 by bolts 18.

[0036] When the card holder 3 has four mounting holes spaced at intervals on the front and back, it is used to install four needle-type filters. After passing through the four connecting through holes in the middle, the four bolts 18 are screwed into the threaded holes at the four corners on the upper side of the card holder 3. In this way, the card holder 3 with four needle-type filters can be detachably and fixedly installed together with the fixing frame 2 by bolts 18.

[0037] When the upper side of the card holder 3 is provided with six mounting holes at intervals, it is used to install six needle-type filters. After passing through the four connecting through holes on the outside, four bolts 18 are screwed into the threaded holes at the four corners on the upper side of the card holder 3. In this way, the card holder 3 with six needle-type filters can be detachably and fixedly installed together with the fixing frame 2 by bolts 18. In this way, the fixing frame 2 can be matched with the card holder 3 that installs a variety of numbers of needle-type filters, and the corresponding card holder 3 can be flexibly selected according to actual needs.

[0038] Example 6: As an optimization of the above examples, as shown in the appendix Figure 1 As shown, two support columns 5 are evenly distributed on the upper side of the push plate 4 at the front and rear positions of the screw 7 of the scissor jack 1, with a scale mark 19 on the outer side of each support column 5.

[0039] According to the requirements, the support column 5 is a columnar structure with graduations. By turning the handle with reference to the graduation mark 19 on the support column 5, the lifting distance of the push plate 4 can be observed, thereby achieving precise and stable filtration.

[0040] As needed, before use, turn the handle, and the screw 7 rotates counterclockwise. The lower end of the upper support arm and the upper end of the lower support arm retract inward (closer to each other), and the push plate 4 is raised to its highest position. After the syringe filter has absorbed enough water sample, install the disposable filter head 14 at the injection port. Then, insert the syringe filters into the first limiting hole 16 in sequence and lock them in place. Install the mounting bracket 3 on the lower side of the fixed frame 2, and use bolts 18 to fix the fixed frame 2 and the mounting bracket 3 together. Then, adjust the length of the handle appropriately according to the filtration difficulty. The handle is a splicable structure and is spliced ​​through the threaded joint. The greater the filtration difficulty, the longer the handle needs to be. Slowly turn the handle, and the screw 7 rotates clockwise, and the upper support... The lower end of the arm and the upper end of the lower support arm expand outward (away from each other). The push plate 4 moves slowly downward under the push of the top seat 9 of the scissor jack 1 and the support column 5. When the pressing plate 13 of the needle filter is located in the circular groove 15 at the lower end of the push plate 4, stop rotating the handle. At this time, record the scale corresponding to the screw 7 on the support column 5. Then, rotate the handle to start pushing the pressing plate 13 to filter. During the filtration process, the volume can be precisely controlled according to the scale change on the support column 5. After the filtration is completed, rotate the handle counterclockwise, and the push plate 4 is raised to the highest position again. Unscrew the bolt 18 between the fixing frame 2 and the card seat 3, and take out the needle filter to complete the filtration operation.

[0041] The multi-channel high-efficiency filter booster of this application can convert rotational motion into linear motion, allowing operators to filter water samples by rotating the handle. This ensures the uniformity of filtration and improves the accuracy and stability of the filtration operation. On the other hand, this application provides three sizes of multi-hole holders 3 (2, 4, and 6), which can filter up to 6 water samples simultaneously, greatly improving filtration efficiency and reducing the burden on operators. Furthermore, the handle can be flexibly adjusted in length according to the actual filtration difficulty, which can reduce the difficulty of injection and reduce the burden on operators.

[0042] The above technical features constitute various embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
