Description
Technical Field
[0001] This utility model relates to the field of fly ash detection technology, specifically to a combined fly ash leaching and filtration device. Background Technology
[0002] Fly ash detection is used to detect heavy metals in fly ash. Before fly ash detection, it needs to be pretreated. The pretreatment process consists of four steps: crushing, leaching, filtration and digestion. The sample needs to be transferred multiple times during the pretreatment process.
[0003] The containers currently used in the fly ash leaching pretreatment process are conventional cylindrical polyethylene bottles. During long-term inversion and oscillation, the polyethylene bottles installed on the inverting oscillator are prone to falling off, causing the experiment to be stopped and seriously affecting the experimental efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a combined fly ash leaching and filtration device that is compact in structure, easy to assemble and disassemble, and conducive to improving experimental efficiency, in order to address the shortcomings of the existing technology.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A combined fly ash leaching and filtration device includes a leaching bottle and a filtrate collection bottle. The leaching bottle has an external thread at its mouth, and the filtrate collection bottle has an internal thread at its mouth, allowing for a detachable connection between the two. The leaching bottle has a vent with a control valve on its side, the filtrate collection bottle has a sand core at its mouth, and an air extraction port on its side. A gasket is placed between the leaching bottle mouth and the sand core, a waterproof membrane is placed between the gasket and the leaching bottle mouth, and a microporous filter membrane is placed between the gasket and the sand core. A membrane rupture assembly is located inside the bottle mouth. When the fly ash leaching in the leaching bottle is complete and filtration is required, the air extraction port is connected to a vacuum pump, and the waterproof membrane between the gasket and the bottle mouth is ruptured by the membrane rupture assembly, allowing the leachate in the leaching bottle to be extracted into the filtrate collection bottle.
[0007] As a further improvement of this utility model, the bottle mouth end is provided with an annular step, the gasket presses the waterproof membrane into the annular step, or the waterproof membrane is pressed between the gasket and the top of the annular step, and the membrane breaking component is provided along the inner wall of the bottle mouth.
[0008] As a further improvement of this utility model, the bottle mouth is provided with an annular hollow region, and the membrane breaking component is disposed within the annular hollow region.
[0009] As a further improvement of this utility model, the membrane-breaking assembly includes a limit switch, an annular blade, and a spring. One end of the spring is fixed to the bottom of the bottle opening, and the other end of the spring is connected to the annular blade, with the annular blade facing the top of the bottle opening. One end of the limit switch is located outside the bottle opening, and the other end of the limit switch is sealed and nested in the side of the bottle opening and supported at the connection between the annular blade and the spring. The setting direction of the limit switch is perpendicular to the movement direction of the annular blade. The limit switch is used to control the annular blade to puncture the waterproof membrane.
[0010] As a further improvement of this utility model, the side of the filtrate collection bottle is also provided with a filtrate collection port, and a valve is provided in the filtrate collection port to control the closure or opening of the filtrate collection port.
[0011] As a further improvement of this utility model, the gasket is made of rubber material.
[0012] As a further improvement of this utility model, the waterproof membrane is an elastic waterproof membrane.
[0013] As a further improvement of this utility model, the limit switch is a pin.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] This utility model relates to a combined fly ash leaching and filtration device. The leaching bottle and filtrate collection bottle are connected by a threaded connection to form a recessed unit. This recess matches a tilting vibrator, allowing the leaching bottle and filtrate collection bottle to be mounted as a single unit on the vibrator for oscillation. This prevents the leaching bottle from falling off during the tilting process, improving the safety of fly ash leaching. Furthermore, the filtrate collection bottle has a non-removable sand core at its opening and an air extraction port on its side. A gasket is placed between the opening of the leaching bottle and the sand core, and a waterproof membrane is placed between the gasket and the opening of the leaching bottle to prevent the leachate in the leaching bottle from leaking out. During the oscillation process, a microporous filter membrane is installed between the gasket and the sand core to meet the requirements of vacuum filtration. At the same time, a membrane rupture component is installed inside the mouth of the leaching bottle. When the fly ash in the leaching bottle has been leached and vacuum filtration is required, the air extraction port is connected to a vacuum pump, and the waterproof membrane between the gasket and the bottle mouth is punctured by the membrane rupture component. This achieves the goal of filtration of the leachate in the leaching bottle into the filtrate collection bottle, thus completing the two pretreatment steps of fly ash leaching and filtration in the same device. This reduces the number of fly ash sample transfers, shortens the experimental time, improves experimental efficiency, and reduces the harm of fly ash samples to experimental personnel.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0026] Example 1
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the combined fly ash leaching and filtration device of this utility model includes a leaching bottle 1 and a filtrate collection bottle 2. The leaching bottle 1 has an external thread 7 at its mouth 11, and the filtrate collection bottle 2 has an internal thread 8 at its mouth, allowing for a detachable connection between the two. Furthermore, the diameter of the bottle mouth is smaller than the diameter of the bottle body, so after the leaching bottle 1 and the filtrate collection bottle 2 are connected, they form a recessed combined structure in the middle, facilitating connection and fixation to the tilting oscillator, and preventing the combined fly ash leaching and filtration device from detaching from the tilting oscillator. The side of the leaching bottle 1 has a vent 15 with a control valve. The vent 15 is closed during the fly ash oscillating leaching process and is only opened after leaching is complete and filtration is required, ensuring that the filtrate can be drawn into the filtrate collection bottle 2. The filtrate collection bottle 2 has a non-removable sand core 4 at its mouth and an air extraction port 5 on its side. A gasket 10 is placed between the mouth 11 of the leaching bottle 1 and the sand core 4. A waterproof membrane is placed between the gasket 10 and the mouth 11 of the leaching bottle 1, and a microporous filter membrane is placed between the gasket 10 and the sand core 4. A membrane rupture assembly is located inside the mouth 11. When the fly ash in the leaching bottle 1 has been leached and filtration is required, the air extraction port 5 is connected to a vacuum pump, and the waterproof membrane between the gasket 10 and the mouth 11 is ruptured by the membrane rupture assembly, thereby allowing the leachate in the leaching bottle 1 to be extracted into the filtrate collection bottle 2. It is understood that in other embodiments, the leaching bottle 1 and the filtrate collection bottle 2 can also be connected by a snap-fit connection, as long as the connection between the leaching bottle 1 and the filtrate collection bottle 2 forms a whole without affecting the oscillating leaching process and facilitating the extraction of the leachate.
[0028] In this embodiment, the leaching bottle 1 and the filtrate collection bottle 2 are connected by a threaded connection to form a recessed whole. The recess matches the tilting shaker, allowing the leaching bottle 1 and the filtrate collection bottle 2 to be installed as a whole on the tilting shaker for vibration. This prevents the leaching bottle from falling off during the tilting vibration process and improves the safety of fly ash leaching. Furthermore, a non-removable sand core 4 is provided at the mouth of the filtrate collection bottle 2, and an air extraction port 5 is provided on the side of the filtrate collection bottle 2. A gasket 10 is provided between the mouth 11 of the leaching bottle 1 and the sand core 4, and a waterproof membrane is provided between the gasket 10 and the mouth of the leaching bottle 1 to prevent the leachate in the leaching bottle 1 from spilling out during vibration. A microporous filter membrane is provided between the gasket 10 and the sand core 4 to meet the requirements of vacuum filtration. Meanwhile, a membrane breaking component is installed inside the mouth 11 of the leaching bottle 1. When the fly ash leaching in the leaching bottle 1 is completed and filtration is required, the suction port 5 is connected to the vacuum pump, and the waterproof membrane between the gasket 10 and the mouth 11 is punctured by the membrane breaking component. This achieves the filtration of the leachate in the leaching bottle 1 into the filtrate collection bottle 2, thus achieving the goal of completing the two pretreatment steps of fly ash leaching and filtration in the same device. This reduces the number of fly ash sample transfers, reduces the experimental time, improves experimental efficiency, and reduces the harm of fly ash samples to experimental personnel.
[0029] like Figure 2 As shown, an annular step 14 is provided at the end of the bottle opening 11. The gasket 10 presses the waterproof membrane tightly within the annular step 14. The membrane-breaking assembly is arranged along the inner wall of the bottle opening 11 and located inside the annular step 14. In this embodiment, the waterproof membrane is an elastic waterproof membrane. When the waterproof membrane is punctured, it will automatically shrink to allow the leachate in the leaching bottle 1 to flow out from the bottle opening 11.
[0030] In other embodiments, the waterproof membrane can also be pressed between the gasket 10 and the top of the annular step 14. Since the membrane puncture assembly is located inside the annular step 14, it will automatically shrink when the waterproof membrane is punctured, and the leachate flow channel will open.
[0031] like Figure 2As shown, the membrane-breaking assembly includes a limit switch 3, an annular blade 12, and a spring 13. One end of the spring 13 is fixed to the bottom of the bottle mouth 11, and the other end of the spring 13 is connected to the annular blade 12, with the annular blade 12 facing the top of the bottle mouth 11. One end of the limit switch 3 is located outside the bottle mouth 11, and the other end of the limit switch 3 is sealed and nested in the side of the bottle mouth 11 and supported at the connection between the annular blade 12 and the spring 13. The setting direction of the limit switch 3 is perpendicular to the movement direction of the annular blade 12. The limit switch 3 is used to control the annular blade 12 to puncture the waterproof membrane. It can be understood that during oscillation, the limit switch 3 is locked at the end of the spring 13, the spring 13 is in a contracted state, and the blade edge of the annular blade 12 is higher than the bottom of the annular step 14, with a gap between it and the waterproof membrane. When filtration is required, the limit switch 3 is activated, the spring 13 is released from its restraint and extends, and the annular blade 12 moves towards the top of the bottle mouth 11 to puncture the waterproof membrane. After filtration is complete, manually move the annular blade 12 toward the bottom of the bottle mouth 11 and re-lock the limit switch 3 onto the end of the spring 13.
[0032] In this embodiment, the limit switch 3 can be in the form of a pin. When vacuum filtration is required, simply move the limit switch 3 gently to release the restriction on the end of the spring 13; the limit switch 3 does not need to be completely removed from the side of the bottle opening 11.
[0033] like Figure 1 As shown, the filtrate collection bottle 2 is also provided with a filtrate collection port 6 on its side. The filtrate collection port 6 is equipped with a valve to control the closure or opening of the filtrate collection port 6. During the shaking and filtration process, the filtrate collection port 6 is in a closed state. After the filtration is completed, the filtrate collection port 6 is opened, and the filtrate in the filtrate collection bottle 2 is poured out from the filtrate collection port 6.
[0034] In this embodiment, the gasket 10 is made of rubber material. It can both isolate the waterproof membrane and the microporous filter membrane and provide a seal to prevent the leachate from leaking from the connection between the leachate bottle 1 and the filtrate collection bottle 2.
[0035] In this embodiment, the working process of the combined fly ash leaching and filtration device includes:
[0036] (1) Place the leaching bottle 1 with the bottle mouth 11 facing upwards, add the required amount of fly ash and leaching solution, and place the waterproof membrane, gasket 10 and microporous filter membrane in sequence at the bottle mouth 11 of the leaching bottle 1.
[0037] (2) Tighten the filtrate collection bottle 2 and the leaching bottle 1 together, and install them on the inverted shaker for leaching by shaking;
[0038] (3) After leaching is complete, place the apparatus with leaching bottle 1 on top and filtrate collection bottle 2 on the bottom.
[0039] (4) Move the limit switch 3 to make the ring blade 12 pierce the waterproof membrane, open the control valve of the vent 15, and connect the suction port 5 to the vacuum pump for filtration.
[0040] (5) After filtration is completed, the filtrate is poured out from the filtrate collection port 6 to obtain fly ash leachate for relevant analysis and testing.
[0041] Example 2
[0042] like Figure 4 , Figure 5 and Figure 6 As shown, the combined fly ash leaching and filtration device of this embodiment has a similar structure and working principle to the combined fly ash leaching and filtration device in Embodiment 1. The main difference is that the bottle mouth 11 is provided with an annular hollow area 9, and the membrane breaking component is set in the annular hollow area 9, which can both puncture the waterproof membrane and reduce the contact between the membrane breaking component and the leachate.
[0043] like Figure 5 As shown, the inner wall end of the bottle mouth 11 is lower than the outer wall end of the bottle mouth 11, and the waterproof membrane is mainly pressed against the gasket 10 through the outer wall end of the bottle mouth 11. An annular hollow region 9 is formed between the inner wall and the outer wall of the bottle mouth 11. The annular blade 12 and the spring 13 are disposed in the annular hollow region 9. The limit switch 3 passes through the outer wall of the bottle mouth 11 and abuts against the end of the spring 13. When leaching is required, the limit switch 3 is activated, the spring 13 is unrestricted and extends, and the annular blade 12 moves toward the top of the bottle mouth 11 to puncture the waterproof membrane. Since the inner wall end of the bottle mouth 11 does not contact the waterproof membrane, when the waterproof membrane is punctured, it will automatically contract, and the leachate in the leaching bottle 1 will flow out from the bottle mouth 11.
[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
