Description

Technical Field

[0001] The invention relates to the technical field of leaching detection, and in particular to a multi-station leaching detection device capable of automatically adding liquid and discharging materials. Background Art

[0002] In many industries such as chemical, food, and medicine, leaching detection devices are widely used in the process of leaching solutes from solids and testing solutions. Although traditional leaching detection devices can meet basic leaching needs to a certain extent, they still have many shortcomings in automation and intelligence. Especially in the full process of automatic sample addition, liquid extraction, and cleaning, existing devices often find it difficult to achieve efficient, accurate, and convenient automated operations, which greatly limits the application scope and detection efficiency of leaching detection devices.

[0003] Specifically, existing leaching detection devices have obvious limitations in the following aspects:

[0004] Manual operation is cumbersome: Traditional leaching detection devices mostly rely on manual operations such as adding liquid, taking liquid and cleaning samples. This not only increases the labor intensity of operators, but also easily leads to operational errors due to human factors, affecting the accuracy of the test results;

[0005] Low degree of automation: The existing leaching detection devices have obvious shortcomings in automation, which makes it impossible for the device to achieve full-process automated operation of samples, thus limiting the improvement of detection efficiency.

[0006] Therefore, a multi-station leaching detection device capable of automatically adding liquid and discharging materials is needed to overcome the occurrence of the above problems. Summary of the invention

[0007] In order to solve the above problems, an embodiment of the present invention provides a multi-station leaching detection device capable of automatically adding liquid and discharging materials, thereby achieving the purpose of solving the problems raised in the background technology.

[0008] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: a multi-station leaching detection device capable of automatically adding liquid and discharging materials, comprising a device body, the outside of the device body is rotatably connected to a turntable, and the turntable is provided with a detection tube;

[0009] The device body is provided with a plurality of workstations for performing different operations on the detection tube;

[0010] The multiple workstations include a feeding station for adding the material to be tested into the detection tube, a liquid adding station for adding the solvent into the detection tube, a sampling station for extracting the sample from the detection tube, and a cleaning station for cleaning the detection tube, which are arranged in sequence along the rotation direction of the turntable.

[0011] As a further improvement of the above technical solution:

[0012] The liquid adding station comprises a metering pump arranged on the device body.

[0013] The cleaning station comprises a nozzle arranged on the device body for spraying cleaning liquid, and a gas nozzle arranged on the device body for spraying compressed gas.

[0014] The sampling station comprises a base plate arranged on the device body, an electric guide rail arranged on the base plate, a sampling tube arranged on the electric guide rail, and a filter block arranged at the end of the sampling tube.

[0015] The device body is provided with a heating component for heating the detection tube;

[0016] The heating assembly comprises a heating seat which is arranged on the device body through an electric push rod.

[0017] The sampling station also includes a cover arranged below the substrate; the substrate is movably arranged on the device body through a moving component;

[0018] The moving assembly comprises a second electric push rod arranged on the device body, and a third electric push rod arranged at the piston end of the second electric push rod; the base plate is fixedly connected to the piston end of the third electric push rod.

[0019] The device body is provided with a cleaning component for cleaning the filter block;

[0020] The cleaning component comprises a cleaning chamber arranged on the device body, two nozzles arranged on the cleaning chamber for spraying cleaning liquid, and two air nozzles arranged on the cleaning chamber for spraying compressed gas.

[0021] The filter block comprises a block body, a through hole opened inside the block body, and a filter screen fixedly connected to one side of the block body and covering the through hole.

[0022] The rotating disk is rotatably connected to a rotating ring via a spring torsion shaft, and four rotating rings are provided, and detection tubes are provided inside the four rotating rings;

[0023] The device body is provided with a guide plate for adjusting the position of the detection tube.

[0024] The device body comprises a base, a column fixedly connected to the inside of the base, and a drainage pipe connected to the side of the base;

[0025] The turntable is rotatably arranged outside the column through a driving assembly;

[0026] The driving assembly comprises a first gear fixedly connected to the turntable, a motor arranged on a column, and a second gear arranged on an output shaft of the motor.

[0027] The beneficial effects of the embodiments of the present invention are:

[0028] In actual use, when the detection tube is in the feeding station, the user adds the material to be tested into the detection tube, and then the turntable rotates to move the detection tube to the liquid adding station to add the solvent, and then the turntable rotates to move the detection tube to the sampling station to sample the solution for testing, and then the turntable rotates to the cleaning station for cleaning; that is, the device can realize the automated operation of liquid adding, sampling, and cleaning of the detection operation, without manual liquid adding, sampling, and cleaning, reducing the labor intensity of personnel and facilitating actual use;

[0029] The sampling tube is provided with an extraction port, through which the solution is extracted. The extraction port is located above the filter block. When the filter block enters the solution, the solution above the filter block has been filtered by the filter block. At this time, the solution extracted from the extraction port is relatively pure, which is convenient for testing the solution.

[0030] The solution inside the detection tube is heated by a heating component to increase the dissolution rate of the components to be detected inside the material in the solvent;

[0031] After the solvent is heated by the heating component, the solvent vapor tends to adhere to the inner wall of the detection tube to form liquid droplets, resulting in a reduction in the actual amount of the solvent at the bottom of the detection tube. When the solution at the bottom of the detection tube is sampled through the sampling tube, the filter block located inside the detection tube can scrape the inner wall of the detection tube, thereby scraping the liquid droplets on the inner wall of the detection tube into the bottom of the detection tube, so that the liquid droplets are re-dissolved into the solution, reducing the impact of the actual amount of solvent reduction on the detection result;

[0032] After the opening of the detection tube is sealed by the cover, the volatilized or evaporated solvent can be prevented from leaking out. At the same time, after the opening of the detection tube is sealed by the cover, as the heating component heats the detection tube, the pressure inside the detection tube is increased, the boiling point of the solvent is increased, and the evaporation caused by the boiling of the solvent is prevented from being aggravated. At the same time, when the pressure inside the detection tube is increased, the pressure increases, so that the volatilization speed of the solvent is reduced; the formation of solvent vapor can be reduced by pressurization, thereby reducing the liquid droplets on the inner wall of the detection tube;

[0033] Through the function of the guide plate, the detection tube is in different tilting states when it is in different workstations, so that different workstations can perform different operations on the detection tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0051] See also Figures 1 to 7The embodiment of the present invention discloses a multi-station leaching detection device capable of automatically adding liquid and discharging materials, comprising a device body 1, a turntable 2 is rotatably connected to the outside of the device body 1, and a detection tube 3 is arranged on the turntable 2;

[0052] The device body 1 is provided with a plurality of stations for performing different operations on the detection tube 3;

[0053] The plurality of workstations include a feeding station 4 for adding a material to be tested into the detection tube 3, a liquid adding station 5 for adding a solvent into the detection tube 3, a sampling station 6 for extracting a sample from the detection tube 3, and a cleaning station 7 for cleaning the detection tube 3, which are sequentially arranged along the rotation direction of the turntable 2;

[0054] In actual use, when the detection tube 3 is in the feeding station 4, the user adds the material to be tested into the detection tube 3, and then the turntable 2 rotates to move the detection tube 3 to the liquid adding station 5 for adding solvent, and then the turntable 2 rotates to move the detection tube 3 to the sampling station 6 for sampling and testing of the solution, and then the turntable 2 rotates to the cleaning station 7 for cleaning; that is, the device can realize the automated operation of liquid adding, sampling and cleaning of the detection operation, without manual liquid adding, sampling and cleaning, thereby reducing the labor intensity of personnel and facilitating actual use.

[0055] As a further illustration of this application:

[0056] The liquid adding station 5 comprises a metering pump 51 arranged on the device body 1;

[0057] As the turntable 2 rotates, the detection tube 3 moves to the bottom of the quantitative pump 51 , and the quantitative pump 51 adds a quantitative amount of solvent into the detection tube 3 , so that the components to be detected in the material are dissolved in the solvent.

[0058] As a further illustration of this application:

[0059] The cleaning station 7 includes a nozzle 71 disposed on the device body 1 for spraying cleaning liquid, and a gas nozzle 72 disposed on the device body 1 for spraying compressed gas;

[0060] As the turntable 2 rotates, the detection tube 3 moves to the cleaning station 7. First, the nozzle 71 sprays cleaning liquid to clean the inside of the detection tube 3. After the cleaning is completed, the air nozzle 72 sprays compressed gas to blow and dry the inside of the detection tube 3. After the drying is completed, the detection tube 3 can be cleaned.

[0061] As a further illustration of this application:

[0062] The sampling station 6 includes a substrate 61 disposed on the device body 1, an electric guide rail 62 disposed on the substrate 61, a sampling tube 63 disposed on the electric guide rail 62, and a filter block 64 disposed at the end of the sampling tube 63; the sampling tube 63 is connected to an extraction pump, and the extraction pump is used to extract the solution inside the detection tube 3 for detection; the detection can be performed by manual detection or by detection instruments; the specific detection method and steps are not repeated in this application;

[0063] As the turntable 2 rotates, the detection tube 3 moves to the sampling station 6. At this time, the material has been immersed in the solvent for a certain period of time, so that the components to be detected inside the material to be detected are dissolved in the solvent to form a solution. The solution inside the detection tube 3 is extracted through the sampling tube 63 for detection;

[0064] When the solution in the detection tube 3 is extracted, the electric guide rail 62 drives the sampling tube 63 to move, so that the sampling tube 63 is inserted into the detection tube 3. As the sampling tube 63 is inserted, the filter block 64 enters the solution, and then the sampling tube 63 extracts the solution.

[0065] The sampling tube 63 is provided with an extraction port, through which the solution is extracted. The extraction port is located above the filter block 64. When the filter block 64 enters the solution, the solution above the filter block 64 has been filtered by the filter block 64. At this time, the solution extracted from the extraction port is relatively pure, which is convenient for detecting the solution.

[0066] As a further illustration of this application:

[0067] The device body 1 is provided with a heating component 8 for heating the detection tube 3; the heating component 8 heats the solution inside the detection tube 3 to increase the dissolution rate of the components to be detected inside the material in the solvent;

[0068] The heating assembly 8 includes a heating seat 82 disposed on the device body 1 through an electric push rod 81; a heating sheet is disposed inside the heating seat 82, and the material of the heating sheet can be a PET electric heating film polyester heating sheet, an aluminum foil heating sheet, etc.;

[0069] As the turntable 2 rotates, the detection tube 3 moves to the sampling station 6. At this time, the electric push rod 81 extends, so that the heating seat 82 moves upward and fits on the bottom of the detection tube 3, thereby heating the solution inside the detection tube 3.

[0070] As a further illustration of this application:

[0071] The sampling station 6 further includes a cover 65 disposed below the substrate 61; the substrate 61 is movably disposed on the device body 1 through a moving assembly 9;

[0072] When testing, the purpose of adding solvent is to dissolve certain components in the sample for subsequent analysis and testing; common solvents include ethanol, methanol, acetone, etc. Solvents are usually alcohols, ethers, ketones, etc. Such solvents are highly volatile, especially after being heated by the heating component 8, the volatilization or evaporation of the solvent is enhanced, resulting in a decrease in the actual amount of the solvent. During testing, quantitative testing is required, that is, the material to be tested and the solvent need to be added quantitatively. After heating, the actual amount of the solvent is reduced, so that the concentration of the component to be tested inside the solution is increased, resulting in errors in the actual test results;

[0073] Therefore, when heating the detection tube 3, the cover 65 is first closed at the opening of the detection tube 3 by moving the component 9, so as to reduce the influence of the volatilization or evaporation of the solvent on the detection result; it should be noted that when the heating component 8 heats the solution, the heating temperature needs to be lower than the boiling point of the solution;

[0074] After the solvent is heated by the heating assembly 8, the solvent vapor tends to adhere to the inner wall of the detection tube 3 to form liquid droplets, resulting in a reduction in the actual amount of the solvent at the bottom of the detection tube 3. When the solution at the bottom of the detection tube 3 is sampled by the sampling tube 63, the filter block 64 located inside the detection tube 3 can scrape the inner wall of the detection tube 3, thereby scraping the liquid droplets on the inner wall of the detection tube 3 into the bottom of the detection tube 3, so that the liquid droplets are re-dissolved into the interior of the solution, thereby reducing the impact of the actual amount of the solvent reduction on the detection result;

[0075] After the opening of the detection tube 3 is sealed by the sealing cap 65, the leakage of the volatilized or evaporated solvent can be prevented. At the same time, after the opening of the detection tube 3 is sealed by the sealing cap 65, as the heating component 8 heats the detection tube 3, the pressure inside the detection tube 3 is increased, and the boiling point of the solvent is increased to prevent the evaporation from being intensified due to the boiling of the solvent; at the same time, when the pressure inside the detection tube 3 is increased, the pressure increases, so that the volatilization rate of the solvent is reduced; by pressurizing, the formation of solvent vapor can be reduced, thereby reducing the number of liquid droplets on the inner wall of the detection tube 3.

[0076] The moving assembly 9 includes an electric push rod 2 91 disposed on the device body 1, and an electric push rod 3 92 disposed at the piston end of the electric push rod 2 91; the base plate 61 is fixedly connected to the piston end of the electric push rod 3 92;

[0077] When the detection tube 3 moves to the sampling station 6 , the electric push rod 91 moves, thereby driving the base plate 61 to move downward, so that the cover 65 is pressed against the opening of the detection tube 3 to seal it.

[0078] As a further illustration of this application:

[0079] The device body 1 is provided with a cleaning component 10 for cleaning the filter block 64; after sampling, since the filter block 64 contacts the solution, the filter block 64 needs to be cleaned by the cleaning component 10 to avoid detection errors of the next solution due to the solution adhering to the filter block 64;

[0080] The cleaning assembly 10 includes a cleaning chamber 101 disposed on the device body 1, a second nozzle 102 disposed on the cleaning chamber 101 for spraying cleaning liquid, and a second air nozzle 103 disposed on the cleaning chamber 101 for spraying compressed gas;

[0081] When cleaning the filter block 64, first the electric push rod 2 91 moves to separate the cover 65 from the opening of the detection tube 3, then the electric push rod 3 92 moves to move the cover 65 to the cleaning chamber 101, then the electric push rod 2 91 moves to snap the cover 65 onto the cleaning chamber 101, then the cleaning liquid is sprayed out through the nozzle 2 102 to clean the filter block 64, and at the same time the electric guide rail 62 moves to move the sampling tube 63 downward so that the cleaning liquid cleans the sampling tube 63; since only a small part of the sampling tube 63 will contact the solution, the sampling tube 63 only needs to move a small part downward for cleaning; the sewage generated after cleaning is discharged through the pipe below the cleaning chamber 101, and after cleaning is completed, compressed gas is sprayed out through the air nozzle 2 103 to blow and dry the filter block 64;

[0082] The sampling tube 63 can be subsequently cleaned by extracting a cleaning fluid. It should be noted that the cleaning fluid must be drained after extraction to prevent residual cleaning fluid from affecting the test results.

[0083] As a further illustration of this application:

[0084] The filter block 64 includes a block body 641, a through hole 642 opened inside the block body 641, and a filter screen 643 fixedly connected to one side of the block body 641 and covering the through hole 642;

[0085] In actual use, the diameter of the block 641 is the same as the inner diameter of the detection tube 3, so that the block 641 can scrape the inner wall of the detection tube 3 when moving. The through hole 642 is provided to balance the air pressure below and above the block 641, so that the block 641 can move normally inside the detection tube 3; by providing the filter 643, the solution entering the top of the block 641 is filtered through the filter 643.

[0086] As a further illustration of this application:

[0087] The rotating disk 2 is rotatably connected with a rotating ring 11 through a spring torque shaft. There are four rotating rings 11, and detection tubes 3 are arranged inside the four rotating rings 11; that is, the four detection tubes 3 are respectively located at four stations, so that adding materials, adding liquid, sampling and cleaning can be carried out at the same time, thereby improving efficiency;

[0088] The detection tube 3 is inserted and fixed inside the rotating ring 11, and the detection tube 3 can be replaced;

[0089] The device body 1 is provided with a guide plate 12 for adjusting the position of the detection tube 3;

[0090] By setting a spring torsion shaft (not shown in the figure), the mouth of the detection tube 3 has a tendency to rotate close to the center of the device body 1; at the same time, the support of the guide plate 12 makes the detection tube 3 in different tilt states;

[0091] When the detection tube 3 is located at the feeding station 4, the guide plate 12 makes the detection tube 3 in a state where the tube mouth is tilted upward, which is convenient for adding materials into the detection tube 3; when adding solid materials, the solid materials are placed at the tube mouth of the detection tube 3 so that the materials slide into the bottom of the detection tube 3 along the tilted detection tube 3, so as to avoid the solid materials directly adding the solid materials into the vertical detection tube 3 and smashing the bottom of the detection tube 3;

[0092] When the detection tube 3 is located at the liquid adding station 5, the detection tube 3 is in a vertical state through the action of the guide plate 12. When the solvent is added, the solvent can directly reach the bottom of the detection tube 3 to prevent the solvent from adhering to the inner wall of the detection tube 3;

[0093] When the detection tube 3 is located at the sampling station 6, the detection tube 3 is in a vertical state through the action of the guide plate 12, that is, the axis of the detection tube 3 and the axis of the sampling tube 63 are in the same position, so that the filter block 64 can move normally inside the detection tube 3 when the sampling tube 63 moves;

[0094] When the detection tube 3 is located at the cleaning station 7, the guide plate 12 makes the detection tube 3 in a downwardly inclined state. When the inside of the detection tube 3 is rinsed by the nozzle 71, the cleaning liquid can flow out along the detection tube 3. At the same time, when the detection tube 3 is blown dry by the air nozzle 72, the cleaning liquid beads inside the detection tube 3 can be discharged along the detection tube 3.

[0095] That is, through the action of the guide plate 12 , the detection tube 3 is in different tilting states when it is in different workstations, so that different workstations can perform different operations on the detection tube 3 .

[0096] As a further illustration of this application:

[0097] The device body 1 includes a base 13, a column 14 fixedly connected to the inside of the base 13, and a drain pipe 15 connected to the side of the base 13; by setting the base 13, the base 13 can collect the sewage generated by the cleaning station 7 and then discharge it through the drain pipe 15;

[0098] The turntable 2 is rotatably arranged outside the column 14 through the driving assembly 16; the driving assembly 16 can drive the turntable 2 to rotate, so that the detection tube 3 moves to different positions;

[0099] The driving assembly 16 includes a gear 161 fixedly connected to the turntable 2, a motor 162 arranged on the column 14, and a gear 2 163 arranged on the output shaft of the motor 162; the gear 2 163 is meshed with the gear 1 161, and when the motor 162 is started, it drives the gear 2 163 to rotate, thereby driving the gear 1 161 to rotate, and the turntable 2 can be driven to rotate.
