Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laboratory test equipment, in particular to a test bench and a test table. BACKGROUND

[0002] The silicate petrochemical analysis test includes a rare earth element measurement part, which includes a sample decomposition step, and the specific steps are as follows:

[0003] First, weigh the sample and mix it with sodium peroxide in a pyrolytic graphite crucible, then add sodium peroxide to cover it.

[0004] Second, place the pyrolytic graphite crucible in a porcelain crucible, cover it and place it in a muffle furnace to heat it to a molten state, then take it out.

[0005] Third, after the graphite crucible cools down, place it in a beaker filled with boiling water and heat it on an electric hot plate until the molten material completely dissolves, then let the sample stand overnight.

[0006] Fourth, filter the extracted liquid with filter paper and collect the filtered liquid. Rinse the filter container with sodium hydroxide solution.

[0007] Fifth, dissolve the precipitate with hot nitric acid, and after cooling, dilute it with nitric acid.

[0008] Sixth, take the dissolved solution from the third step, dilute it and use it directly for ICP-MS (inductively coupled plasma mass spectrometry) measurement.

[0009] As can be seen, in the above steps, both acidic and basic waste liquid will be produced, and the required filtered liquid will be produced, the waste liquid is produced by rinsing the funnel, and the required filtered liquid is the solution filtered by the funnel.

[0010] The waste liquid produced by rinsing the funnel needs to be discarded, and the solution filtered by the funnel needs to be collected. If the existing test bench in the prior art is used, the output medium storage container of the funnel needs to be switched when discarding the waste liquid and filtering the filtered liquid. At this time, the funnel needs to be removed, placed in a container, and then placed in the funnel stand. Since the test often needs to collect a large amount of test data, this simple process will also waste a lot of time of the test personnel after accumulation, reducing the test efficiency. SUMMARY

[0012] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present application provides a test bench and a test table, which solve the technical problem of the prior art that the test bench needs to switch the output medium storage container of the funnel when discarding waste liquid and filtering the filtered liquid, at which time the funnel needs to be removed, the container is placed, and then the funnel is placed on the funnel frame after adjustment, and due to the fact that a large amount of test data needs to be collected during the test, the simple process will also waste a lot of time of the test personnel after accumulation, thereby reducing the test efficiency.

[0074] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figures 1-15 The present invention will be described in detail through specific embodiments. In this document, "upper" and "lower" are used to refer to specific parts of the invention. Figure 1 Using the orientation as a reference, "left" and "right" are... Figure 7 The orientation is used as a reference.

[0075] Example 1:

[0076] Reference Figures 1-7 An embodiment of the present invention provides a test bench, including a funnel rack 1, a test tube rack 2, and a waste liquid pool 3 arranged vertically in sequence. Both the funnel rack 1 and the test tube rack 2 can be supported on the waste liquid pool 3. The funnel rack 1 can switch between a first position and a second position relative to the test tube rack 2. When the funnel rack 1 is in the first position, the output port of the funnel supported on the funnel rack 1 extends vertically into the waste liquid pool 3. When the funnel rack 1 is in the second position, the position of the output port of the funnel supported on the funnel rack 1 corresponds to the opening position of the test tube supported on the test tube rack 2.

[0077] The test bench also includes a test tube holder 10, which is located in the waste liquid tank 3 to support the test tubes. The waste liquid tank 3 includes an output pipe to discharge the waste liquid out of the waste liquid tank 3.

[0078] In the embodiment, the funnel rack 1, the test tube rack 2 and the waste liquid pool 3 are integrated into one test bench, and the funnel rack 1 has a first position and a second position, when the funnel rack 1 is in the first position, the output port of the funnel supported on the funnel rack 1 extends vertically into the waste liquid pool 3, when the funnel rack 1 is in the second position, the position of the output port of the funnel supported on the funnel rack 1 corresponds to the opening position of the test tube supported on the test tube rack 2, and the output port of the funnel extends into the test tube, by adjusting the funnel rack 1 to switch between the first position and the second position, the funnel can be matched with the cleaning working condition and the filtering working condition, thereby realizing the switching of the funnel cleaning working condition and the filtering working condition without disassembling the funnel and the test tube, which can greatly improve the test efficiency.

[0079] The funnel and the test tube are supported by the funnel rack 1 and the test tube rack 2, and in the cleaning working condition and the filtering working condition of the funnel, the test personnel do not need to move the funnel and the test tube, which greatly improves the test safety and reduces the probability of the test personnel contacting the test articles.

[0080] The funnel rack 1, the test tube rack 2 and the waste liquid pool 3 are arranged vertically in sequence, which can reduce the space occupation of the test bench and improve the structural compactness of the test bench.

[0081] The second position and the first position can be arranged in the form of 180° angle along the vertical direction, so that the funnel can be cleaned and filtered on both sides of the rotation axis of the funnel rack 1, thereby ensuring the independence of the cleaning process and the filtering process.

[0082] Specifically, the funnel rack 1 can be arranged to rotate relative to the test tube rack 2, that is, the funnel rack 1 is switched between the first position and the second position by rotating, and there is a change in height during the rotation, and the height of the second position is higher than that of the first position. The first position is arranged lower to make the output port of the funnel extend as far as possible into the waste liquid pool 3 to alleviate the splashing problem when the funnel outputs waste liquid; the second position is arranged higher to make the output port of the funnel correspond to the opening of the test tube to ensure that the filtrate output by the funnel can be collected by the test tube.

[0083] More specifically, the funnel rack 1, the test tube rack 2 and the waste liquid pool 3 can all be made of polytetrafluoroethylene material.

[0084] In the embodiment, the test bench further comprises a support, one end of the support is supported on the waste liquid pool 3, and the funnel rack 1 and the waste liquid pool 3 are connected to the support; the support comprises an outer tube 4 and an inner rod 5, the inner rod 5 is rotationally connected in the outer tube 4, and the inner rod 5 can also slide vertically relative to the outer tube 4, one end of the outer tube 4 is fixedly connected with the waste liquid pool 3, the test tube rack 2 is connected to the outer tube 4, and the funnel rack 1 is connected to the inner rod 5; when the inner rod 5 rotates relative to the outer tube 4, the test tube rack 2 can be switched between the first position and the second position.

[0085] In the embodiment, the funnel frame 1 and the test tube frame 2 are supported by the support on the waste liquid pool 3, and the support also meets the requirement that the funnel frame 1 can be switched, the support comprises an outer tube 4 and an inner rod 5, the outer tube 4 is fixed on the waste liquid pool 3, and the inner rod 5 is rotationally connected in the outer tube 4, the inner rod 5 can drive the funnel frame 1 connected with the inner rod 5 to rotate, and then the funnel frame 1 is switched between the first position and the second position.

[0086] Specifically, since the funnel frame 1 is switched from the first position to the second position, there is not only an angle change but also a height change, therefore, the inner rod 5 needs to be arranged to be rotatable relative to the outer tube 4, and also vertically slidable, and also to keep the relative position with the outer tube 4, and then to ensure that the funnel frame 1 can be kept in the first position and the second position.

[0087] More specifically, in order to be more safe and convenient, the outer tube 4 and the inner rod 5 can both be made of polytetrafluoroethylene material.

[0088] In the embodiment, the support further comprises a track 6 and a latch 7 matched with each other, the track 6 is arranged on the outer tube 4, the latch 7 is connected to the inner rod 5, and the axis of the latch 7 extends horizontally; the track 6 comprises a first limiting area 61 and a second limiting area 62 which are communicated with each other, when the latch 7 matches with the first limiting area 61, the funnel frame 1 keeps the first position, when the latch 7 matches with the second limiting area 62, the funnel frame 1 keeps the second position, and the funnel and the test tube do not interfere with each other during the running of the latch 7 along the track 6.

[0089] In the embodiment, the track 6 is used to guide the rotation of the latch 7, and then when the latch 7 rotates, the inner rod 5 must also change in height relative to the outer tube 4 to match the position change requirement of the test tube frame 2.

[0090] The track 6 can be arranged as a through slot opened on the outer tube 4, and the latch 7 can be arranged as a metal pin connected to the inner tube, and the latch 7 slides in the track 6.

[0091] The latch 7 can be kept in the first limiting area 61 and the second limiting area 62, and then the inner rod 5 can keep the funnel frame 1 in the first position and the second position.

[0092] Specifically, the latch 7 can be arranged as a cylindrical pin, the first limiting area 61 and the second limiting area 62 are arranged as circular grooves, and match with the latch 7 with a gap, when the latch 7 enters the first limiting area 61 or the second limiting area 62, the inner rod 5 is pressed against the corresponding first limiting area 61 or second limiting area 62 under the action of external force, and then the latch 7 can be kept in the corresponding first limiting area 61 or second limiting area 62.

[0093] More specifically, the external force can be the vertical downward gravity of the inner rod 5 and the funnel frame 1, or the elastic force of the spring 8 applied to the inner rod 5 to keep the inner rod 5 in an upward sliding trend.

[0094] In the embodiment, the support further comprises a spring 8, which is arranged in the outer tube 4 and has two ends abutting against the lower end of the inner rod 5 and the lower end of the outer tube 4, respectively.

[0095] In the embodiment, the spring 8 keeps applying a vertical upward elastic force to the inner rod 5, so that the plug 7 can be kept in the corresponding first limiting area 61 or second limiting area 62 when the plug 7 is in the first limiting area 61 or the second limiting area 62, and the tightness of the plug 7 and the track 6 can be improved when the inner rod 5 rotates, thereby improving the stability of the inner rod 5 when rotating.

[0096] The support further comprises a knob 9 connected to the inner rod 5.

[0097] In the embodiment, the knob 9 is fixedly connected to the inner rod 5, and the inner rod 5 can be driven to rotate synchronously by rotating the knob 9.

[0098] Embodiment 2:

[0099] With reference to Figure 6 and Figures 8-11 , the embodiments of the present application further have the following technical solutions in addition to all the technical solutions of any of the above embodiments.

[0102] Specifically, the plug 7 is first run to the higher third connection section C, in order to reserve sufficient margin to ensure that the test tube does not interfere with the plug 7, and for the test tube with a larger opening, the output port of the funnel can also extend into the test tube, specifically, when the plug 7 is in the fourth connection section D, the output port of the funnel corresponds to the opening of the test tube, when the plug 7 descends along the fourth connection section D, the output port of the funnel will gradually enter the opening of the test tube, and when the plug 7 runs in the fifth connection section E, the output port of the funnel also remains in the opening of the test tube when the plug 7 is in the second limiting area 62, so that the spitting of the filtered liquid output by the funnel can be avoided when it is output.

[0105] The track 6 includes a first reversing area F, a second reversing area G, a third reversing area H, a first channel I and a second channel J, the first reversing area F is communicated with the first limiting area 61 through the first channel I, and the third reversing area H is communicated with the second limiting area 62 through the second channel J; when the plug 7 is located in the first reversing area F, the plug 7 can enter the second reversing area G by pressing the inner rod 5 downward, when the plug 7 is located in the second reversing area G, the spring 8 can press the inner rod 5 upward to make the plug 7 enter the third reversing area H, and when the plug 7 is located in the third reversing area H, the spring 8 can press the inner rod 5 upward to make the plug 7 enter the second limiting area 62.

[0106] In the embodiment, another implementation form of the track 6 is provided, that is, the reversing action of the lever when running in the track 6 is realized through the first reversing area F, the second reversing area G and the third reversing area H, and the position switching process of the funnel frame 1 from the first position to the second position can be realized by repeatedly pressing the inner rod 5, thereby improving the convenience of the funnel frame 1 when switching positions.

[0107] Specifically, the height of the second switching area G is higher than the height of the third switching area H, and the height of the third switching area H is higher than the height of the second switching area G. When the plug 7 is in the second switching area G, the height of the output port of the funnel is higher than the height of the opening of the test tube.

[0108] For a test tube with a larger opening, the output port of the funnel can also extend into the test tube. Specifically, when the plug 7 is in the third switching area H, the output port of the funnel corresponds to the opening of the test tube and extends into the test tube. In this way, the splashing of the filtered liquid output by the funnel can be avoided when it is output.

[0109] In this embodiment, the first switching area F has a first inflection point F1 and a second inflection point F2, the second inflection point F2 is located below the first inflection point F1, and the plug 7 can run to the second inflection point F2 position when the inner rod 5 is descending; and when the inner rod 5 is ascending, it runs upward from the second inflection point F2 position and runs along the track 6 to the second switching area G under the guidance of the first inflection point F1; the second switching area G has a third inflection point G1 and a fourth inflection point G2, the fourth inflection point G2 is located below the second inflection point F2, and the plug 7 can run to the third inflection point G1 position when the inner rod 5 is ascending; and when the inner rod 5 is descending, it runs downward from the third inflection point G1 position and runs along the track 6 to the third switching area H under the guidance of the fourth inflection point G2; the third switching area H has a fifth inflection point H1 and a sixth inflection point H2, the sixth inflection point H2 is located below the fifth inflection point H1, and the plug 7 can run to the sixth inflection point H2 position when the inner rod 5 is descending; and when the inner rod 5 is ascending, it runs upward from the sixth inflection point H2 position and runs along the track 6 to the second limiting area 62 under the guidance of the fifth inflection point H1.

[0110] In this embodiment, the second inflection point F2 is located at the lower right of the first inflection point F1, the fourth inflection point G2 is located below the third inflection point G1, and the sixth inflection point H2 is located below the fifth inflection point H1. The first switching area F and the second switching area G are connected by the first channel I and the second channel J, respectively. Under the guidance of each inflection point to the plug 7, the rotation of the inner rod 5 can be realized by repeatedly pressing the inner rod 5, and the funnel frame 1 can be switched from the first position to the second position.

[0111] The process of switching the funnel frame 1 from the second position to the first position is manually realized, that is, rotating the inner rod 5 according to the extension of the track 6.
