Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical reagent and auxiliary agent filtration equipment, and more specifically, to a chemical reagent and auxiliary agent filtrate collection device. Background Technology
[0002] Currently, in laboratory filtration of chemical reagents and auxiliaries, filter paper is first filled into a funnel. Then, the tubing below the funnel is placed against the side wall of a beaker. A guide rod is used to direct the filtration solution into the filter paper. Finally, the solution passes through the filter paper and is collected in the beaker below. While the open-top structure of the beaker is suitable for common auxiliaries, it poses safety hazards for toxic auxiliaries such as formaldehyde, APEO, PFOS, PFOA, and carcinogenic aromatic amines. Furthermore, the close proximity of personnel to the equipment during experiments means that even slight shaking can cause the filtrate to spill, potentially harming their health. Therefore, a specialized collection device for such toxic auxiliaries is needed. Utility Model Content
[0003] The purpose of this invention is to provide a chemical reagent filtrate collection device. This filtrate collection device is equipped with a closed protective experimental chamber, which allows for the filtrate collection of auxiliaries inside the experimental chamber, protecting the health of external experimental personnel. At the same time, the collected filtrate can be sealed and moved outside the experimental chamber for collection, improving the safety of auxiliary collection.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A chemical reagent auxiliary filtrate collection device includes a guide rod, a funnel, and a beaker. The funnel is filled with filter paper. The collection device includes an experimental chamber with openings on the top and front sides, and a transparent observation glass is installed on the front side. A top cover is embedded in the top of the experimental chamber, and a lifting handle is fixed to the rear end of the top cover. A through hole is opened in the middle area of the top cover, and an inlet tube is inserted obliquely into the through hole. The lower end of the inlet tube is close to the middle position of the guide rod. The lower part of the guide rod is attached to the surface of the filter paper inside the funnel. The lower end of the funnel extends into the beaker, and a sealing cap is fitted over the opening area of the beaker.
[0006] As a further optimization of this solution, the surface of the closed cover is machined with a rectangular through groove, and a baffle is slidably embedded in the rectangular through groove. The outer side of the baffle is machined into an arc surface and presses against the side below the funnel. Several return springs are connected between the inner end of the outer side of the baffle and the rectangular through groove. In the initial state, the several return springs push the baffle to the edge of the closed cover.
[0007] As a further optimization of this solution, the bottom surface of the experimental chamber is machined with a downwardly recessed groove, and a beaker is placed inside the groove. A rectangular through groove is opened at the lower end of one side of the experimental chamber, and a circular through groove is opened at the lower end of the other side of the experimental chamber. The groove extends out of the rectangular through groove on one side of the experimental chamber to the outside of the experimental chamber. A switch door is connected to the outside of the rectangular through groove via a rotating shaft. When the switch door is closed, it is limited by a strip-shaped sealing ring on the inside of the rectangular through groove.
[0008] As a further optimization of this solution, a sleeve is installed through the circular through groove, and a top rod passes through the inside of the sleeve. A vertically parallel push frame is installed at the inner end of the top rod. The push frame is attached to the side of the beaker. The beaker is pushed to one side of the experimental chamber by the push frame, opening the switch door and passing through the rectangular through groove into the sliding groove outside the experimental chamber.
[0009] As a further optimization of this solution, the top cover surface is provided with a connecting strip facing downwards, and the lower end of the connecting strip is connected to a concave frame with an inward opening. The upper and lower sides of the horizontal section of the concave frame are respectively connected to a small support ring and a large support ring. The small support ring passes through the drainage rod, and the large support ring supports the funnel.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0011] This invention designs an experimental chamber structure that can accommodate components such as a flow guide rod, funnel, and beaker inside the experimental chamber. The filtration aid liquid is introduced through the liquid inlet pipe, allowing the experimenter to complete the filtration operation inside the experimental chamber while operating from the outside, thus protecting the health of the experimenter.
[0012] This invention utilizes a design incorporating a sleeve, a push rod, a push frame, and a sliding groove to move a beaker from inside the experimental chamber to a sliding groove outside the chamber. Simultaneously, a closed cap structure is installed above the beaker's opening to temporarily seal the filtrate inside, facilitating transport by external personnel and improving the safety of additive collection.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0020] To address the safety hazards of existing beaker collection methods, and the fact that experimenters are too close to the experimental equipment, and that slight shaking during the experiment can easily cause the filtrate to spill out, potentially harming their health;
[0021] like Figure 1 As shown, this application includes a guide rod 4, a funnel 5, and a beaker 6. The funnel 5 is filled with filter paper 19. The collection device includes an experimental box 1. The experimental box 1 is open at the top and on the front side, and a transparent observation glass 13 is installed on the front side. A top cover 14 is embedded in the top of the experimental box 1. A lifting handle 2 is fixed to the rear end of the surface of the top cover 14. A through hole is opened in the middle area of the surface of the top cover 14, and an inlet tube 3 is inserted obliquely into the through hole. The lower end of the inlet tube 3 is close to the middle position of the guide rod 4. The lower part of the guide rod 4 is attached to the surface of the filter paper 19 inside the funnel 5. The lower end of the funnel 5 extends into the beaker 6. A sealing cap 7 is fitted on the upper opening area of the beaker 6.
[0022] like Figure 3 and Figure 4 As shown, a rectangular through groove is machined on the surface of the closed cover 7, and a baffle 20 is slidably embedded in the rectangular through groove. The outer side of the baffle 20 is machined into an arc surface and presses against the lower side of the funnel 5. Several return springs 21 are connected between the inner end of the outer side of the baffle 20 and the rectangular through groove. In the initial state, the several return springs 21 push the baffle 20 to the edge of the closed cover 7.
[0023] like Figure 1As shown, the bottom surface of the experimental chamber 1 is machined with a downwardly recessed groove 12, and a beaker 6 is placed inside the groove 12. A rectangular through groove is opened at the lower end of one side of the experimental chamber 1, and a circular through groove is opened at the lower end of the other side of the experimental chamber 1. The groove 12 extends out of the rectangular through groove on one side of the experimental chamber 1 to the outside of the experimental chamber 1. A switch door 11 is connected to the outside of the rectangular through groove through a rotating shaft. When the switch door 11 is closed, it is limited by the strip sealing ring 22 inside the rectangular through groove.
[0024] A sleeve 8 is installed through the inside of the circular groove, and a push rod 9 passes through the inside of the sleeve 8. A vertically parallel push frame 10 is installed at the inner end of the push rod 9, and the push frame 10 is attached to the side of the beaker 6.
[0025] like Figure 5 As shown, the beaker 6 pushes the frame 10 toward one side of the experimental chamber 1, opening the switch door 11 and passing through the rectangular through slot into the sliding groove 12 outside the experimental chamber 1.
[0026] like Figure 2 As shown, the top cover 14 has a connecting strip 15 facing downwards. The lower end of the connecting strip 15 is connected to a concave frame 16 with an inward opening. The upper and lower sides of the horizontal section of the concave frame 16 are respectively connected to a small support ring 17 and a large support ring 18. The small support ring 17 passes through the drainage rod 4 and the large support ring 18 supports the funnel 5.
[0027] Specifically, when filtering the auxiliaries, beaker 6 is placed on the slide groove 12 inside the experimental chamber 1, so that the other side of beaker 6 is in contact with the push frame 10. The beaker 6 is covered with a sealing cover 7, and then the top cover 14 is placed on top of the experimental chamber 1. Through the transparent observation glass 13, the baffle 20 under the funnel 5 is pushed open and extended into the beaker 6. At this time, the return spring 21 is compressed inward, so that the outer arc surface of the baffle 20 presses against the side of the funnel 5.
[0028] Beforehand, filter paper 19 is filled into the inner arc surface of funnel 5. The filtration aid solution is poured into the experimental chamber 1 through the inlet tube 3. The filtration aid solution is guided by the guide rod 4 into the surface of the filter paper 19 for filtration. The filtrate flows from below funnel 5 into beaker 6. After the filtration is completed, the experimenter pulls up the top cover 14 by pulling handle 2 and pulls beaker 6 out from below funnel 5. During the process, baffle 20 will move to the initial position under the elastic force of return spring 21, temporarily sealing the top of beaker 6. At the same time, the experimenter pushes the top rod 9 inward, which pushes the frame 10 to push beaker 6 to one side of experimental chamber 1. Beaker 6 pushes open the switch door 11 and passes through the rectangular through groove into the slide groove 12 outside experimental chamber 1. At this time, the experimenter can take out the transfer beaker 6 from the slide groove 12. The experimenter can perform the filtration operation outside experimental chamber 1 throughout the entire process, which is safe.
