Description

Technical Field

[0001] The utility model relates to the technical field of water sample filtering and washing, in particular to a device for water sample filtering and washing. Background Art

[0002] In the water analysis project of chemical technical supervision of power plants, it is required to conduct a full water quality analysis of raw water, circulating water and industrial water every quarter. Many items of the full water quality analysis require filtering and washing of water samples or solutions, and it is generally required to wash until the filtrate is free of chloride ions. During the filtering and washing process, tiny impurities in the external environment will fall into the beaker, causing pollution to the filtrate, and then causing errors in the analysis results after the water sample is filtered and washed, and the filtrate will be lost during the detection of chloride ions. In order to avoid impurities from contaminating the filtrate, filter paper will be added to the top opening of the beaker in the prior art to cover the opening. However, to detect chloride ions, the filtrate must be taken at the bottom of the funnel, and the bottom of the funnel must be lifted out of the beaker, which will inevitably lose the filtrate, and even the filter paper covering the beaker will be soaked and damaged.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Figure 1 Schematic diagram of a device for filtering and washing water samples according to an embodiment of the utility model. Figure 1 As shown, the device comprises: an iron frame 1, a funnel frame 2 is slidably mounted on the upright column of the iron frame 1, a funnel 3 is clamped inside the funnel frame 2, a first filtrate outlet 4 is arranged at the bottom of the funnel neck of the funnel 3, a second filtrate outlet 5 is arranged at the upper side of the funnel neck of the funnel 3, an adjusting knob 6 is arranged on the funnel neck of the funnel 3 below the second filtrate outlet 5, and a beaker 7 is arranged below the first filtrate outlet 4.

[0016] Specifically, the funnel 3 is used to filter and wash the water sample, and the filtered filtrate to be collected flows into the beaker 7 through the first filtrate outlet 4;

[0017] The adjusting knob 6 is used to control the on and off of the filtrate in the funnel neck of the funnel 3;

[0018] The second filtrate outlet 5 is used to flow out the filtrate to be tested when the adjustment knob 6 is closed.

[0019] Preferably, if Figure 1 As shown, a beaker cover 8 is provided on the top of the beaker 7 .

[0020] Figure 2 It is a schematic diagram of a beaker cover provided according to the number of the utility model. Figure 2 As shown, a notch 9 is provided on the beaker cover 8 , and the first filtrate outlet 4 extends into the interior of the beaker 7 through the notch 9 .

[0021] Preferably, in the embodiment of the present utility model, the beaker cover 8 is a glass vessel.

[0022] Preferably, if Figure 2 As shown, a handle 10 is provided on the top of the beaker cover 8 for easy lifting and placing.

[0023] The utility model provides a beaker cover 8 with a notch 9 on the top of the beaker 7, which can prevent dust and other debris from entering the beaker 7 when the water sample is filtered and washed, thereby avoiding affecting the accuracy of the measurement of the filtering and washing results of the water sample; and prevent the filtrate from dripping onto the outside of the beaker 7.

[0024] Preferably, the terminal level of the second filtrate outlet 5 is lower than the filtrate liquid level inside the funnel 3 .

[0025] The present invention provides a device for filtering and washing water samples, and its working principle is as follows:

[0026] When filtering the water sample, control the adjusting knob 6 to open and wash 3-5 times. At this time, the filtrate flows directly into the beaker 7 through the adjusting knob 6 and the first filtrate outlet 4; when it is necessary to detect whether the chloride ions are washed clean, close the adjusting knob 6, and the filtrate will be stored in the column at the upper end of the adjusting knob 6. When the water level is higher than the end of the second filtrate outlet 5, the filtrate will flow out from the second filtrate outlet 5 (wherein the end of the second filtrate outlet 5 should be lower than the liquid level of the funnel 3); after taking enough filtrate to detect the chloride ions, open the adjusting knob 6 again, and the filtrate is collected into the beaker 7 as usual, which effectively avoids the loss of filtrate and the inconvenience of operation.

[0027] The utility model designs a glass vessel similar to a teacup with a cover on the top of the beaker 7, leaving a position for the funnel 3 (i.e., the notch 9), and the inner edge of the beaker cover 8 is completely matched with the beaker 7. At the same time, a glass handle (i.e., the hand-held portion 10) is designed to facilitate lifting and placing, effectively preventing external impurities from falling into the beaker, thereby avoiding affecting the accuracy of the filtration and washing result determination of the water sample, and alleviating the technical problem of filtrate loss in the prior art during the process of lifting the bottom of the funnel out of the beaker.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
