Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a batch filtration device. Background Technology

[0002] Vacuum filtration (also known as vacuum filtration or vacuum pressure reduction filtration) is a commonly used laboratory technique that uses a vacuum pump or suction device to reduce the air pressure within a filtration system, thereby accelerating solid-liquid separation through pressure difference. Its core principle is to reduce the pressure difference across the filter medium (such as filter paper or filter membrane), allowing the liquid to quickly pass through the filter material under negative pressure, while solid particles are retained, thus achieving efficient separation.

[0003] Currently, laboratory filtration often employs methods such as... Figure 1 The filtration device shown. Figure 1 In this setup, a Buchner funnel (b) is installed at the top opening of a filtration flask (a). The flask has a lateral vent pipe (c), which is connected to a vacuum pump (d). During filtration, the medium is placed on the filter paper in the Buchner funnel (b), and the vacuum pump (d) is started to perform the filtration. This apparatus cannot perform batch filtration. For some experiments, a large amount of dry medium needs to be prepared beforehand. Using this apparatus might require multiple rounds of filtration, which could affect the experimental process.

[0004] Based on this, the present invention proposes a batch filtration device to solve the problems mentioned above. Utility Model Content

[0025] The batch filtration device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0026] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0027] like Figure 2 As shown in the figure, this utility model embodiment proposes a batch filtration device, including a box body 1, a box cover 2 and an air extraction device (not shown in the figure);

[0028] Specifically, a suction pipe 3 is connected to the upper end of the outer side wall of the box 1, and the suction pipe 3 is connected to the air extraction device; the box cover 2 is installed on the top of the box 1, referring to the reference. Figure 3 The end face of the box cover 2 is provided with multiple mounting holes 4 through it.

[0029] In the material preparation stage before the experiment, a suitable Buchner funnel was inserted into each installation hole 4, and a filter element was placed in each Buchner funnel. The medium was then placed in each funnel. Then, the pumping device was started to achieve batch filtration of the medium, which effectively shortened the preparation time before the experiment.

[0030] Furthermore, each of the mounting holes 4 is equipped with an adjustment element for adjusting its diameter; referring to reference Figure 5 The adjusting component includes multiple inserts 5 of different diameters. The multiple inserts 5 are nested in the mounting hole 4 from the inside to the outside according to the diameter from small to large. The innermost insert 5 is covered with a sealing plug 6.

[0031] By selecting different numbers of inserts 5 to match the mounting holes 4, the mounting holes 4 can have various through-hole diameters, thus adapting to different specifications of Buchner funnels and greatly improving the applicability of the equipment. Furthermore, due to the sealing plug 6, the number of working stations can be selected according to actual conditions. For example, if the medium to be pumped only requires three Buchner funnels operating simultaneously, then three mounting holes 4 can be left unsealed with the sealing plug 6, while the remaining mounting holes 4 can be sealed using inserts 5 and sealing plugs 6.

[0032] In summary, the batch filtration device provided in this embodiment, through the configuration of the housing 1, the air extraction device connected to the housing 1, and the housing cover with multiple mounting holes 4, can realize the simultaneous filtration operation of multiple Buchner funnels, effectively shortening the preparation time before the experiment; furthermore, through the setting of the adjustment component, the aperture of the mounting holes 4 can be adjusted, so that the device can meet the filtration operation of Buchner funnels of various different specifications, ensuring the good applicability of the device.

[0033] In the above implementation process, in order to ensure the sealing between each insert 5 of the adjusting component, the sealing between the adjusting component and the mounting hole 4, and the sealing between the Buchner funnel and the mounting hole 4 and the insert 5, a sealing ring 7 is installed on the inner side wall of each insert 5 and the inner side wall of the mounting hole 4.

[0034] In the above embodiments, preferably, the lid 2 is detachably installed on the top of the box body 1, and to ensure the seal between the lid 2 and the box body 1, sealing gaskets 10 are provided around the top surface of the box body 1. Figure 4 As shown.

[0035] The cover 2 is detachable, which makes it easy to clean and maintain the inside of the box 1.

[0036] Specifically, the lid 2 can be fixed with screws. Multiple screws are screwed into the lid 2 from the top and connected to the top of the box body 1. When the lid 2 needs to be removed, the screws can be removed.

[0037] Even better, the lid 2 is fixed to the box body 1 with a flexible snap fastener, making the removal of the lid 2 more convenient.

[0038] It should be noted that the specific method by which the lid 2 is fixed to the body 1 using elastic fasteners is existing technology and will not be elaborated upon here.

[0039] In one specific embodiment, a discharge valve 8 is installed at the lower end of the outer side wall of the housing 1.

[0040] Furthermore, the bottom surface of the box 1 is configured as a funnel shape, the lowest point of the bottom surface of the box is located above the discharge valve 8, and a connecting pipe 9 is connected to the lowest point of the bottom surface of the box. The end of the connecting pipe 9 away from the lowest point of the bottom surface of the box 1 is connected to the discharge valve 8.

[0041] By setting the bottom surface of the tank 1 in a funnel shape, and in conjunction with the discharge valve 8, it is convenient to discharge and collect the liquid medium collected in the tank 1.

[0042] To facilitate monitoring the liquid level inside tank 1 and to allow for timely drainage of the liquid medium, an observation window 12 is provided on the side wall of tank 1, and a scale (not shown in the figure) is installed on the observation window 12.

[0043] In an optional embodiment, the suction pipe 3 is connected to the housing 1 and the suction device via a quick connector 11. The quick connector 11 enables quick installation and removal of the suction pipe 3, thereby facilitating the storage of the device.

[0044] In another optional embodiment, a handle 13 is provided on the outer wall of the housing. The handle 13 facilitates the handling of the device.

[0045] In summary, the batch filtration device provided by this utility model, through the configuration of a box, an air extraction device connecting the box, and a box cover with multiple mounting holes, enables simultaneous filtration of multiple Buchner funnels, effectively shortening the preparation time before the experiment. Furthermore, through the setting of the adjustment component, the aperture of the mounting holes can be adjusted, so that the device can meet the filtration operations of Buchner funnels of various specifications, ensuring the good applicability of the device.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
