Description

Technical Field

[0001] The invention relates to the technical field of total amount of material detection, in particular to an automatic lossless transfer device for a solid-liquid mixture used for total amount of material detection and a control method thereof. Background Art

[0002] In the process of chemical analysis and detection, there are experiments to measure the total amount of substances. It is required to transfer the solid-liquid mixture after the treatment of leaching or extraction to the subsequent steps such as volume determination and filtration without loss, so as to ensure that the treated substances to be tested can be completely transferred to the sample bottle to be tested, so as to accurately measure the total amount of specific substances contained in the sample. Most of the leaching or extraction steps are processing steps under harsh or extreme conditions such as high temperature or even oil bath boiling. The lossless transfer of the test object requires rapid transfer under high temperature conditions, and the sample container must be rinsed into the sample bottle to be tested with the original leaching solution or extraction solution for multiple times to ensure that there is no residual substance to prevent affecting the final test results. At the same time, the amount of leaching solution or extraction solution used for rinsing should generally not be too much, which is not conducive to the operation of subsequent links. Too much reagent will lead to the inability to determine the volume and waste reagents, or lead to low filtration efficiency.

[0003] Traditional chemical testing laboratories mostly use manual methods to transfer solids and liquids without loss, which requires skilled operators. At the same time, transferring high-temperature samples poses potential risks to operators, such as burns. The leaching liquid or extraction liquid is generally a high-concentration chemical solution with strong acid, strong alkali, and strong corrosiveness, which poses certain difficulties and risks to operators. In addition, according to relevant research and long-term testing experience, different operating methods of different laboratories and different operators will also lead to different test results, which cannot be compared horizontally.

[0004] In the prior art, although some mechanical technologies can achieve simple test tube dumping, corrected mechanical movement or cleaning operations, from the perspective of chemical processing, lossless transfer is an important part of the pre-treatment of the total amount of material detection, especially for special cases with low material content, a small amount of material (solid-liquid mixture) waste will also produce a large difference in the result of the total amount of material detection. Therefore, for the operation specifications of lossless transfer of solid-liquid mixture, it is not a simple dumping and cleaning operation, and it is necessary to reliably and effectively transfer the residue in the container thoroughly and completely.

[0005] Therefore, how to meet the needs of total amount of material detection and realize automated lossless transfer of solid-liquid mixtures has become a technical problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to have a further understanding and recognition of the structural features and the effects achieved by the present invention, a preferred embodiment and accompanying drawings are used for detailed description as follows:

[0032] like Figure 1 As shown, an automated non-destructive transfer device for solid-liquid mixture for total amount of material detection described in the present invention comprises a liquid receiving cup 1, a nozzle bracket 2, a test tube mounting seat 3 and a reagent spray assembly. The test tube pouring assembly is used to open the test tube 8 obliquely downward to facilitate the solid-liquid mixture inside to flow out into the liquid receiving cup 1 below. The reagent spray assembly is used to provide reagents for adding liquid during the complete transfer stage, the nozzle motion assembly is used to control the nozzle 9 to extend into the test tube 8 or move out of the test tube 8, and the test tube rotation assembly is used to rotate the test tube 8. In the process of transferring the solid-liquid mixture, it is not a simple pouring (transfer), but is also accompanied by operating procedures such as fixed precipitation and control of the total amount of liquid added. Therefore, it is necessary for the test tube pouring assembly, the test tube rotation assembly, the reagent spray assembly and the nozzle motion assembly to work together.

[0033] In the prior art, the traditional manual transfer method is adopted. When solid precipitation occurs, the test tube needs to be shaken continuously after adding liquid or the test tube needs to be rotated continuously when the test tube is inverted. It is not easy to transfer all the precipitation or the residue on the wall, and the final total amount of liquid added cannot be controlled. Therefore, the present invention works under the cooperation of multiple components such as the test tube rotating component and the reagent spraying component, and can realize these processes at the same time.

[0034] For non-contact liquid addition, the reagent liquid spraying assembly and the nozzle motion assembly are used to work together. The rear end of the nozzle motion assembly is installed on the nozzle bracket 2, and the front end of the nozzle motion assembly is installed with a nozzle fixing frame 4, and the front end of the nozzle motion assembly is facing the test tube 8. The nozzle fixing frame 4 is installed with a nozzle regulating tube 5, and the front end of the nozzle regulating tube 5 is installed with a liquid spraying tube 6. The liquid delivery pipe 7 of the reagent liquid spraying assembly is installed at the rear end of the nozzle regulating tube 5.

[0035] A spray head 9 is installed at the front end of the spray pipe 6, and the spray head 9 can extend into the mouth of the test tube 8. Figure 4 As shown, Figure 4 Point A is the liquid jetting position of the nozzle 9, that is, the extension line of the nozzle 9 contacts the upper arc of the bottom of the test tube 8, preferably the upper arc of the bottom of the test tube 8. This is because the liquid jetting of the nozzle 9 can be sprayed on the upper end of the arc at the bottom of the test tube 8 ( Figure 4 The nozzle 9 is pointed at point A in the middle of the test tube 8, that is, the nozzle 9 is not pointed at the bottom center of the test tube 8. The kinetic energy of the liquid flow and the gravity of the liquid flow are used to flush the bottom of the test tube, so that the precipitated part forms a solid-liquid mixture and flows out along the wall of the test tube to achieve the purpose of transfer. The nozzle 9 is pointed to this position, and the test tube 8 is rotated during cleaning, so that the precipitation and wall residues in the test tube 8 can be transferred. It is best to set the extended line of the nozzle 9 (that is, the injection position of the spray liquid flow of the nozzle 9) to an angle of 2°-4° with the longitudinal center line of the test tube 8. The best effect is achieved within this angle range.

[0036] A test tube tilting assembly is mounted on the test tube mounting seat 3, a test tube rotating assembly is mounted inside the test tube tilting assembly, and the test tube 8 is inserted into the test tube rotating assembly. The test tube tilting assembly includes a rotating cylinder 17 mounted on the test tube mounting seat 3, a test tube rotating frame 18 is fixedly mounted on the output shaft of the rotating cylinder 17, and the rotating cylinder 17 can drive the test tube rotating frame 18 to tilt, that is, to achieve the tilting of the test tube 8.

[0037] like Figure 3As shown, the test tube rotating assembly includes a rotating cylinder 19 and a rotating motor 20. The rotating cylinder 19 is installed in the test tube rotating frame 18 and forms a rotational match with the test tube rotating frame 18. The rotating cylinder 19 can be installed on the test tube rotating frame 18 and rotated by various methods in the prior art, such as pin connection, flange, etc. The rotating motor 20 is installed on the outside of the test tube rotating frame 18. The output shaft of the rotating motor 20 passes through the test tube rotating frame 18 (mounted by a traditional bearing) and is fixedly installed on the rotating cylinder 19. The rotating motor 20 drives the rotation of the rotating cylinder 19 to cooperate with the transfer action in the test tube 8. A flexible test tube fixing ring 21 is fixedly installed in the rotating cylinder 19. The flexible test tube fixing ring 21 can be a rubber ring or a silicone ring, which can realize the friction between the test tube 8 and the rotating cylinder, so that the test tube 8 does not slip when tilted, and can drive the test tube to rotate together when rotating.

[0038] like Figure 2 As shown, when the test tube pouring assembly moves to the pouring state and the nozzle moving assembly moves to the maximum load range, the liquid spraying tube 6 is located in the test tube 8 and the test tube mouth of the test tube 8 is located above the liquid receiving cup 1, so that the solid-liquid mixture in the test tube 8 is poured out.

[0039] The nozzle movement assembly includes a cylinder support mounting seat 11, a linear cylinder 12 is mounted on the cylinder support mounting seat 11, a guide rail 13 is fixedly mounted on the cylinder support mounting seat 11, and a nozzle fixing frame 4 is mounted on the guide rail 13 and forms a sliding fit with the guide rail 13, and its sliding fit mode can be a sliding pair connection mode. The nozzle adjustment tube 5 is mounted on the nozzle fixing frame 4, and the nozzle fixing frame 4 is fixedly mounted on the piston rod of the linear cylinder 12, and is controlled by the linear cylinder 12 to extend forward into the test tube 8 or retract and exit the test tube 8.

[0040] The reagent spray assembly includes a liquid adding pump 14, the liquid inlet pipe of the liquid adding pump 14 is installed in the reagent barrel 15, the liquid outlet pipe of the liquid adding pump 14 is installed on the liquid inlet of the pressure valve 16, and the liquid delivery pipe 7 is installed on the liquid outlet of the pressure valve 16. The liquid source pressure is provided for the cleaning operation through the liquid adding pump 14 and the pressure valve 16.

[0041] In order to solve the problems of limited liquid adding capacity and fixed liquid outflow route, the liquid adding pump 14, pressure valve 16 and nozzle 9 are used to control the hydraulic pressure of liquid adding, and the liquid outflow route is controlled by the rotation angle of the rotating cylinder 17, the rotation speed of the rotating motor 20 and the position of the liquid receiving cup 1. The pressure valve 16 ensures that the hydraulic pressure is uniform and stable. The inner diameter of the nozzle 9 should be smaller than the inner diameter of the liquid delivery pipe 7 to achieve liquid collection and injection, and further enhance the injection force. By controlling the rotation angle of the rotating cylinder 17 and the rotation speed of the rotating motor 20, the outflowing liquid is a fixed and uniform arc without splashing, and the arc falls at the position of the liquid receiving cup 1. By controlling the flow rate and time of the peristaltic pump (liquid adding pump 14), it can be ensured that the amount of liquid supplied for each liquid addition transfer is within a stable and controllable range with low error, thereby ensuring that the liquid adding capacity will not exceed the limit.

[0042] In case the added solvent is acid or alkali corrosive solvent, all joints in contact with the liquid are made of polyetheretherketone (PEEK).

[0043] In order to realize the automatic control of the device, Figure 5 As shown, it may also include a main control chip 22 and a nozzle displacement sensor 23. The nozzle displacement sensor 23 is fixedly mounted on the cylinder bracket mounting seat 11 and is located below the piston rod of the linear cylinder 12 to monitor the movement state of the nozzle motion component.

[0044] The data output end of the nozzle displacement sensor 23 is connected to the data input end of the main control chip 22, the control signal input end of the pressure valve 16 is connected to the first control signal output end of the main control chip 22, the control signal input end of the rotary cylinder 17 is connected to the second control signal output end of the main control chip 22, the control signal input end of the rotary motor 20 is connected to the third control signal output end of the main control chip 22, the control signal input end of the linear cylinder 12 is connected to the fourth control signal output end of the main control chip 22, and the control signal input end of the liquid adding pump 14 is connected to the fifth control signal output end of the main control chip 22. The main control chip 22 can obtain the displacement data signal of the nozzle displacement sensor 23, and control the operation of the pressure valve 16, the rotary cylinder 17, the rotary motor 20, the linear cylinder 12, and the liquid adding pump 14.

[0045] Here, an automated control method for an automated non-destructive transfer device for a solid-liquid mixture for detecting the total amount of a substance is also provided, that is, in actual application, it comprises the following steps:

[0046] The first step is the initial transfer of the solid-liquid mixture (the initial transfer time can be agreed to be 15 seconds). After the test tube 8 is installed and limited in the flexible test tube fixing ring 21 of the rotating cylinder 19, the main control chip 22 controls the rotating cylinder 17 to work, so that the test tube rotating frame 18 is in an inclined state, and the solid-liquid mixture in the test tube 8 is poured into the liquid receiving cup 1.

[0047] The second step is the complete transfer of the solid-liquid mixture, by rotating and adding liquid (the liquid is the original extractant) to wash away the remaining solids in the test tube and the liquid remaining on the inner wall.

[0048] The main control chip 22 controls the linear cylinder 12, the liquid adding pump 14, the pressure valve 16 and the rotary motor 20 to clean the test tube 8. The specific steps are as follows:

[0049] (1) The main control chip 22 controls the linear cylinder 12 to move forward, extending the liquid spraying pipe 6 forward. After receiving the trigger signal of the nozzle displacement sensor 23, the main control chip 22 controls the linear cylinder 12 to stop moving;

[0050] (2) The main control chip 22 controls the liquid adding pump 14, the pressure valve 16 and the rotating motor 20 to work synchronously, and the nozzle 9 performs the liquid adding operation on the test tube 8;

[0051] (3) The main control chip 22 controls the liquid adding pump 14, the pressure valve 16 and the rotary motor 20 to stop, and controls the linear cylinder 12 to perform a retraction movement.

[0052] The third step is to restore the initial state. The main control chip 22 controls the linear cylinder 12 to retract and controls the rotary cylinder 17 to reset, thereby restoring the vertical state of the test tube rotating rack 18.

[0053] The automated lossless transfer device of the present invention is specifically used for the early stage of total amount of material detection in chemical treatment. It does not require excessive human intervention, and the mixture in the original container is transferred thoroughly. It is compatible with strong acid and strong alkali solutions, requires fewer reagents, and the inner wall of the container is evenly filled with liquid, avoiding errors caused by manual operation. The present invention automates lossless transfer, reduces system errors to a minimum, and lays a foundation for the standardization of subsequent total amount of material detection.
