Description

Technical Field

[0001] This application relates to the field of monitoring technology, and in particular to multi-parameter analysis devices. Background Technology

[0002] To protect the aquatic environment, it is essential to strengthen the monitoring of wastewater discharge. While new monitoring equipment (such as analytical instruments) using optical and electrical signals has emerged, traditional chemical and physical methods for water quality testing continue to play a role in validating and supplementing these new devices. Historically, these traditional chemical and physical measurement methods relied primarily on manual operation.

[0003] In recent years, automatic monitoring instruments have been widely used in the field of water quality monitoring technology. However, most common automatic water quality monitoring instruments are single-parameter monitoring devices, with each instrument capable of measuring only one specific parameter. If multiple parameters such as total nitrogen and total phosphorus need to be monitored simultaneously, multiple different instruments are required, which not only increases equipment costs but also leads to higher maintenance expenses.

[0004] Currently, there is still a lack of automated monitoring instruments on the market that can simultaneously measure multiple parameters such as total nitrogen and total phosphorus based on chemical methods. Utility Model Content

[0032] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0033] This application provides a multi-parameter analysis device that can analyze at least total phosphorus and total nitrogen in the sample to be tested.

[0034] For example, the total phosphorus testing process is as follows: sampling, adding a solid material packet, shaking, heating and digesting, cooling; adding a second solid material packet, shaking, and drying; adding a third solid material packet, shaking, drying, reacting, and measuring with the analytical section.

[0035] For example, the total nitrogen testing process is as follows: sampling, adding a solid material package, shaking, heating and digesting, cooling; adding a second solid material package, shaking, reacting for a period of time; adding a third solid material package, shaking, reacting, shaking again, reacting, and measuring with the analytical section.

[0036] The multi-parameter analysis device provided in this application can transform the above-mentioned manual testing process into an automated process through mechanical structures.

[0037] For example, see Figure 1 The multi-parameter analysis device may include a tubular container storage section 400, a solid material section 200, a weighing section 500, a mixing section 300, a digestion section 600, and a cooling section 700. Thus, the tubular container 100 (described later) can perform sampling, adding solid material packages, weighing, mixing and shaking, heating and digestion, and cooling at each station.

[0038] See Figure 2 , Figure 3

[0039] The multi-parameter analysis device may also include a pipetting section 900, a tube transfer section 800, a cap opening and closing section, and an analysis section (not shown in the figure).

[0040] The following is a detailed description of each component.

[0041] Tubular container storage section 400

[0042] See Figure 2 The tubular container storage section 400 can store multiple tubular containers 100. For example, the tubular container 100 can be a test tube, and the tubular container 100 can have a lid 110.

[0043] See Figure 3 The multi-parameter analysis device may also include a water sample storage area 410 for storing water samples (the liquid to be tested). Additionally, the multi-parameter analysis device may include a reagent storage area 420 for storing reaction liquids. The reaction liquids may include deionized water as a reference control for the liquid to be tested; the reaction liquids may also include other liquids used for testing.

[0044] Solid Materials Department 200

[0045] See Figure 4 , Figure 5 , Figure 12 , Figure 13 The solid material section 200 can store various solid material packages 211, and is configured to pour the solid material from the solid material package 211 into the corresponding tubular container 100. The solid material in the solid material package 211 can be in the form of powder, granules, etc.

[0046] More specifically, the solid material unit 200 may include a solid material package storage module 210, a solid material package picking module 220, a solid material package conveying track 230, a solid material package clamping module 240, a cutting module 250, and a material distribution module 260.

[0047] See Figure 6 In one example, the solid material package storage module 210 is used to store multiple solid material packages 211 in separate areas. The solid material package storage module 210 may include multiple storage elements 212 arranged in parallel, the storage elements 212 being inclined relative to a horizontal plane, and the solid material packages 211 are arranged and stored in the storage elements 212.

[0048] The solid material package storage module 210 may include a feeding element 213, which is located at one end of the storage element 212. The feeding element 213 abuts against the solid material package 211 through an elastic element (e.g., a spring), thereby pushing the solid material package 211 to the outlet 215 of the storage element 212 under the action of gravity and the elastic element.

[0049] The solid material package storage module 210 may include a blocking element 214. The blocking element 214 is disposed at the outlet 215 and blocks part of the outlet 215, so that the solid material package 211 can pass over the blocking element 214 and leave the solid material package storage module 210 after being picked up by the solid material package pickup module 220. The blocking element 214 can prevent the solid material package 211 from leaving the solid material package storage module 210 when it is not picked up by the solid material package pickup module 220.

[0050] See Figure 12 In another example, the solid material package storage module 210 may include a storage rack 216, a support platform 217, and a lifting element 218. Multiple storage racks 216 may be arranged side-by-side to enable partitioned storage of multiple solid material packages 211 (see [link to documentation]). Figure 12 The storage rack 216 may include a baffle 2161 disposed circumferentially thereon. The baffle 2161 is capable of preventing the solid material package 211 from detaching from the storage rack 216 in the horizontal direction.

[0051] The support platform 217 forms the base plate of the storage rack 216. Solid material packages 211 are stacked in the height direction in the storage space 2162 defined by the support platform 217 and the baffle 2161. The lifting element 218 can drive the support platform 217 to rise or fall relative to the storage rack 216, thereby changing the position of the solid material packages 211. For example, when the support platform 217 is raised, the solid material packages 211 are lifted to the top of the baffle 2161, making it easier for the solid material package picking module 220 to pick up the solid material packages 211. The lifting element 218 can be a device that can perform linear conveying, such as a motor screw or a telescopic cylinder.

[0052] Figure 12 In the example, the solid material package 211 is stacked in the height direction, which can support a large weight and can accommodate various existing material packages. The stacking configuration in the height direction also facilitates the introduction of collaborative robots for palletizing and placement, making it more labor-saving.

[0053] See Figure 7 , Figure 13 The solid material package pickup module 220 is used to pick up solid material packages 211 from a specific area in a controlled manner. The solid material package pickup module 220 includes a suction cup 221 and a pickup arm 222. The suction cup 221 can adsorb the solid material package 211, and the pickup arm 222 can move the suction cup 221 closer to or further away from the solid material package storage module 210.

[0054] More specifically, the picking arm 222 may include a bracket 2221 and a swing arm 2222, the swing arm 2222 being rotatably connected to the bracket 2221, and a suction cup 221 being provided at one end of the swing arm 2222.

[0055] The picking arm 222 may include a linear actuator 2223, which includes a controllable reciprocating link 2224. One end of the link 2224 is rotatably connected to a swing arm 2222. By moving the link 2224, the swing position of the swing arm 2222 can be controlled, allowing the suction cup 221 to move closer to or further away from the solid material package 211 in the solid material package storage module 210. For example, it can pick up the solid material package 211 when it approaches and drive the solid material package 211 away from the solid material package storage module 210 when it moves away. The linear actuator 2223 may be a cylinder, and the link 2224 may be a piston rod. This design facilitates control of the movement distance of the swing arm 2222 and makes it easier to match the tilted storage state of the solid material package 211.

[0056] for Figure 6 The example shown is of a solid material package storage module 210. The solid material package picking module 220 can be used as follows: Figure 7 As shown ( Figure 7Two operating states are shown. When the connecting rod 2224 retracts relative to the body of the linear actuator 2223, the swing rod 2222 tilts, with one end of the swing rod 2222 approaching the solid material package storage module 210, and the suction cup 221 picks up the solid material package 211. When the connecting rod 2224 extends outward relative to the body of the linear actuator 2223, the swing rod 2222 rotates clockwise, the swing rod 2222 is perpendicular to the horizontal plane, and one end of the swing rod 2222 moves away from the solid material package storage module 210, and the suction cup 221 carries the solid material package 211 out of the solid material package storage module 210.

[0057] for Figure 12 The example shown is of a solid material package storage module 210. The solid material package picking module 220 can be used as follows: Figure 13 As shown ( Figure 13 Two operating states are shown. When the connecting rod 2224 extends outward relative to the body of the linear actuator 2223, the swing rod 2222 is parallel to the horizontal plane, and one end of the swing rod 2222 is close to the solid material package storage module 210, picking up the solid material package 211; when the connecting rod 2224 retracts relative to the body of the linear actuator 2223, the swing rod 2222 is perpendicular to the horizontal plane, and one end of the swing rod 2222 is away from the solid material package storage module 210, and the suction cup 221 carries the solid material package 211 out of the solid material package storage module 210.

[0058] See Figure 4 , Figure 12 The solid material bag picking module 220 can be slidably disposed on the solid material bag conveying track 230 and can be controlled to stop at a certain position to pick up a specific solid material bag 211 to meet various measurement requirements. For example, the sliding direction can include the line direction connecting the solid material bag storage module 210 and the solid material bag clamping module 240, also known as the first sliding direction C.

[0059] Additionally, see Figure 12 , Figure 13 The sliding direction can also include the line direction connecting the solid material package storage module 210 and the solid material package conveying track 230, also known as the second sliding direction A. This allows the solid material package picking module 220 to be configured to approach or move away from the solid material package storage module 210.

[0060] More specifically, the solid material package conveying track 230 may include a first slide rail 231 and a second slide rail 232. A slider 233 may be fixedly mounted on the bottom of the solid material package picking module 220. The slider 233 may be slidably mounted on the second slide rail 232 along a second sliding direction A, and the second slide rail 232 may be slidably mounted on the first slide rail 231 along a first sliding direction C, so that the solid material package conveying track 230 can slide in both the first sliding direction C and the second sliding direction A.

[0061] Figure 12 There are two rows of storage racks 216 arranged in the left and right directions. Of course, more rows of storage racks 216 can be arranged.

[0062] See Figure 8 , Figure 9 The solid material package clamping module 240 is configured to clamp and rotate the solid material package 211. More specifically, the solid material package clamping module 240 may include a first mechanical finger 241 and a second mechanical finger 242, which respectively clamp the two sides of the solid material package 211. The first mechanical finger 241 and the second mechanical finger 242 can clamp or release the package by pneumatic, electric or other means.

[0063] After the cutting module 250 cuts the material, rotating the solid material bag clamping module 240 allows the opening of the solid material bag 211 to face downwards, thus completing the powder pouring step. Powder pouring can be assisted by vibration, tilting, or other methods to ensure that the speed and amount of material poured out meet the set standards. At least one of the first mechanical finger 241 and the second mechanical finger 242 can move to adjust the distance between the two fingers, thereby vibrating the solid material bag 211.

[0064] See Figure 9 The solid material bag clamping module 240 can rotate around direction A, allowing the solid material bag 211 to tilt and pour out the solid material. The solid material bag clamping module 240 can also rotate around direction B, aligning the solid material bag 211 with the position of the weighing unit 500 (e.g., ...). Figure 5 (As shown). Direction A can be parallel to the horizontal plane, and direction B can be perpendicular to the horizontal plane.

[0065] See Figure 8 , Figure 12 The cutting module 250 is configured to cut the solid material package 211 held by the solid material package clamping module 240. The cutting module 250 may include pneumatic or electric shears to controllably cut the solid material package 211, for example, by controlling different cutting speeds to cut solid material packages 211 of corresponding materials and sizes. Compared to manual cutting, this cutting module 250 can ensure the accuracy and consistency of the cut. The cutting module 250 can also be a laser cutting module, providing more precise cutting results and suitable for thinner materials. The cutting module 250 can also be an ultrasonic cutting module, suitable for heat-sensitive materials, allowing cutting to be completed without heating the material. It should be understood that... Figure 12 The cutting module 250 is completely covered by a cover, and its specific structure is not shown.

[0066] See Figure 5The material distribution module 260 may include a distribution disc 261, which includes multiple collection ports 262. The distribution disc 261 is controllably rotatable along its axis (i.e., around). Figure 7 (Rotation in direction B).

[0067] The material distribution module 260 may include multiple guiding elements 263, which may be funnels. The multiple guiding elements 263 are respectively connected to multiple collection ports 262. Different guiding elements 263 can be assigned to different locations on the weighing unit 500 according to the different compositions of the materials.

[0068] A cleaning device (not shown in the figure) capable of blowing or sucking air can also be provided to clean the funnel-shaped material guiding element 263 by blowing air, so as to prevent cross-contamination between materials.

[0069] Weighing section 500

[0070] See Figure 5 , Figure 12 The weighing unit is used to weigh the tubular container 100 before the addition of solid material and the tubular container 100 after the addition of solid material. The weighing unit 500 may include a bearing element 510, and the bearing element 510 may have a bearing position 513 (e.g., Figure 3 (as shown) or has multiple bearer bits 513 that can switch positions (e.g.) Figure 12 (As shown). The bearing position 513 includes a support plate 511 with an opening and a support frame 512. The support plate 511 can support the tubular container 100 in the height direction, and the support frame 512 can prevent the tubular container 100 from tipping over. The weighing unit 500 may also include a measuring element 520, which can be raised and lowered in a controlled manner. After the measuring element 520 is raised, it can pass through the opening to lift and measure the weight of the tubular container 100 in the corresponding bearing position 513. The measuring element 520 can be a high-precision electronic balance or other types of weighing unit.

[0071] See Figure 12 In an example where the carrier element 510 has multiple carrier positions 513 that can be switched, the carrier element 510 can be formed as a turntable with multiple carrier positions 513, and the positions of the carrier positions 513 can be switched by rotation. It should be understood that this example allows for the addition or removal of tubular containers 100 to other carrier positions 513 while weighing a tubular container 100 in one carrier position 513, thereby improving overall work efficiency.

[0072] In addition, a control system can be configured to transmit material weight data to the control system of a multi-parameter analysis device, enabling monitoring of production data and facilitating statistical analysis and historical data recording. Each process can be coordinated and managed through the control system, ensuring the accuracy and efficiency of each step. Through continuous optimization and adjustment, efficient and precise cutting, pouring, and weighing of solid material packages can be achieved, improving the level of production automation.

[0073] Mixing section 300

[0074] See Figure 10 The mixing section 300 is used to uniformly mix the liquid substances within the tubular container 100 to obtain a liquid. The mixing section 300 may include a clamping structure 310 and a rotating structure 320. The clamping structure 310 can clamp the tubular container 100 and shake it under the action of the rotating structure 320. For example, the tubular container 100 can be repeatedly inverted, for example, 5 or 6 times, to achieve uniform mixing. The rotating structure 320 can be driven to rotate by a rotary cylinder, motor, etc. The clamping structure 310 can be a gripper, clamping and rotating a single tubular container 100 for uniform mixing. The clamping structure 310 can also be formed as a tubular container support frame, simultaneously rotating and shaking multiple tubular containers 100. The aforementioned "uniform mixing" refers to two or more substances being completely and homogeneously distributed together, forming a state where the composition and properties of each part are consistent. The degree of uniformity can be determined empirically based on the number of shaking cycles.

[0075] Pipette 900

[0076] See Figure 3 The pipetting unit 900 is capable of adding the test liquid and / or reaction liquid into the tubular container 100. The pipetting unit 900 may include a pipette 910 and a first robotic arm 920. The pipette 910 is capable of transferring the test liquid or reaction liquid into the tubular container 100, and the pipette 910 is movable under the action of the first robotic arm 920. The pipette 910 may be a pipette tip, and the pipette tip is designed to be detachable to avoid cross-contamination when aspirating different liquids.

[0077] Transplantation Department 800

[0078] See Figure 2 The transfer unit 800 is capable of moving the tubular container 100 between at least the solid material unit 200, the weighing unit, the mixing unit 300, the pipetting unit 900, and the analysis unit. The transfer unit 800 may include a second robotic arm 810, which is capable of moving the tubular container between multiple workstations. The second robotic arm 810 can pick up the tubular container 100 using a vacuum suction head, test tube clamp, or similar means.

[0079] The first robotic arm 920 and the second robotic arm 810 can be configured to move along tracks in three mutually perpendicular directions, such as X, Y, and Z. Figure 2 Only one direction of the track is shown; it may have two other tracks.

[0080] Analysis Department

[0081] The analysis unit is capable of analyzing liquids from the tubular container 100. The analysis unit can be a water quality analyzer, and exemplaryly, the analysis unit includes at least one of a visible light spectrophotometer, a quantum dot spectral sensor, a turbidity measuring element, a conductivity measuring element, a dissolved oxygen sensor, and a pH measuring element.

[0082] The liquid can be deionized water, a dispersion, a suspension, etc.

[0083] By configuring the analysis section with the corresponding detection units, it is possible to detect substances such as total phosphorus, total nitrogen, COD (chemical oxygen demand), ammonia nitrogen, pH, turbidity, EC (conductivity), and potassium permanganate index.

[0084] Opening and closing cover

[0085] The lid opening / closing section (not shown) is configured to separate or connect the lid 110 to the body of the tubular container 100. The tubular container 100 can be removed from the tubular container storage section 400 and sent to the lid opening / closing device via the tube transfer section 800. After the lid opening or closing operation is performed, the tubular container 100 is moved to another workstation. Alternatively, a separate tubular container loading section, including a robot arm, can be provided to independently pick up the tubular container 100 and send it to the lid opening / closing section.

[0086] The opening and closing mechanism may include a tube body clamping device capable of clamping the tube body of the tubular container 100 and a cap clamping device capable of clamping the cap 110 of the tubular container 100. In one example, the tube body clamping device and the cap clamping device are capable of relative rotation and relative movement, with the tube body and the cap 110 threadedly engaged. Therefore, after being clamped, the tube body and the cap 110 can rotate and move relative to each other, achieving engagement or disengagement. In another example, the tube body clamping device and the cap clamping device are capable of relative movement, with the tube body and the cap 110 having an interference fit. Therefore, after being clamped, the tube body and the cap 110 move towards each other to close the cap 110, and move away from each other to open the cap 110.

[0087] Digestion section 600

[0088] See Figure 11The multi-parameter analysis device may also include a digestion unit 600, which provides a digestion space, and the tubular container 100 is capable of heating and digesting in the digestion space.

[0089] Cooling section 700

[0090] See Figure 11 The multi-parameter analysis device may further include a cooling unit 700. The cooling unit 700 may include a first cooling unit 710, which includes a tubular container support frame 711 in which the tubular container 100 can be placed for natural cooling. The multi-parameter analysis device also includes a second cooling unit 720, which includes a cooling tank 721 in which coolant and the tubular container 100 are placed, allowing the tubular container 100 to be cooled by water cooling.

[0091] Wiping section

[0092] The multi-parameter analysis device may also include a wiping section (not shown in the figure) for wiping the outer wall of the tubular container 100, and a transfer section 800 for moving the tubular container 100 to the wiping section. It should be understood that liquid spillage may occur. Condensation may occur after heating and cooling, and liquid residue may remain after water cooling; therefore, wiping the tubular container 100 is necessary.

[0093] The wiping section may include a wiping robot, a roller brush, etc., with the wiping robot driving the roller brush to rotate and wipe. The wiping section may also include a wiping robot and a wiping cloth, with the wiping robot driving the wiping cloth to move and wipe. For example, the tubular container 100 can be moved to the wiping section for wiping by the tube transfer section 800.

[0094] Before startup, the multi-parameter analysis device can automatically perform self-checks and initialization settings to ensure all equipment is in a ready state. After completing a batch of production, the system cleans and resets to prepare for the next production run. Regular maintenance and calibration of the multi-parameter analysis device can also be performed to ensure long-term stable operation.

[0095] Below, this application provides a COD detection process.

[0096] First, the tubular container 100 is picked up and moved to the opening and closing cap section, where the cap 110 is removed. The sample is then added to the tubular container 100 via the pipetting section 900. Solid material is added to the tubular container 100 and weighed. The tubular container 100 is then sent back to the opening and closing cap section, where the cap is closed. A second robotic arm 810 carries the capped tubular container 100 to the mixing section 300, where it is mixed and shaken. The second robotic arm 810 then carries the shaken tubular container 100 to the wiping section, where it is wiped. The second robotic arm 810 then carries the wiped tubular container 100 to the digestion section 600, where it is heated and digested. Finally, the second robotic arm 810 carries the tubular container 100 to the cooling section. The cooled tubular container 100 is then placed in the analysis section for analysis.

[0097] The advantages of the multi-parameter analysis device provided in this application include:

[0098] (1) It can achieve the measurement of multiple parameters with high efficiency. The solid material section can store and process multiple solid material packages, which enables the provision of the required reagents for the detection of multiple parameters, which is conducive to the realization of multi-parameter detection.

[0099] (2) It helps improve detection accuracy and quality control. Chemical reagents often have very strict dosage requirements; too little or too much dosage may lead to product failure or safety hazards. Automated systems can achieve high-precision metering and dispensing, ensuring that the quality of materials meets strict standards and reducing the production of unqualified products. Precise cutting and powdering mechanisms reduce material waste and contamination, improving product purity and consistency. Automated systems can reduce human error, improve product consistency and stability, thereby improving product quality. Through real-time data collection and recording, the production process can be effectively monitored, and potential problems can be quickly identified and resolved. Analysis of historical data can promote continuous optimization of the production process.

[0100] (3) It helps reduce safety risks. Chemical reagents may be toxic, corrosive, or flammable. Automated systems can free workers from harmful chemicals and repetitive labor, reducing workplace safety risks. Automated equipment can operate in closed or isolated environments, reducing the health impact on operators.

[0101] (4) It helps control costs. Automation reduces manual operation and lowers labor costs. It also reduces waste of raw materials and product loss caused by improper operation.

[0102] In conclusion, automation solutions not only improve production efficiency and product quality, but also enhance operational safety and data management capabilities, while helping to reduce costs and environmental impact, resulting in comprehensive benefits.

[0103] The above description is the preferred embodiment of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
