Description

Technical Field

[0001] The invention relates to the field of drilling fluid detection, and in particular to an automatic detection system for comprehensive properties of drilling fluid. Background Art

[0002] In the detection of drilling fluid performance, apparent viscosity, filtration loss and titration are all very important detection items. Six-speed viscosity and filtration loss, that is, the content of various ions, are very important parameters affecting the performance of drilling fluid. Six-speed viscometer is a common physical property analysis instrument for measuring the viscosity of drilling fluid. Viscosity is a physical property of fluid substances. It reflects the internal friction between molecules when the fluid is subjected to external forces. The viscosity of a substance is closely related to its chemical composition. The existing six-speed viscosity measurement equipment has a relatively single function and can only measure the viscosity of the drilling fluid. After the drilling fluid is measured, the paddle cup, rotor and drum used for measurement need to be manually cleaned, and the waste liquid generated by cleaning cannot be well treated, causing environmental pollution.

[0003] The drilling fluid (mud) is affected by the pressure difference in the well, and some water seeps into the formation. This phenomenon is called the water loss performance or filtration characteristics of the drilling fluid. The water loss (filtration loss) of the drilling fluid has a very important influence on the stability of the drilling fluid system and is an important parameter for maintaining the stability of the well wall. Therefore, in the drilling well site, the drilling fluid engineer or the drilling engineer will frequently measure it. The measurement method in the prior art is to measure it by API water loss meter or high temperature and high pressure water loss meter. The process includes: flipping the instrument upside down and opening the lid, pouring the drilling fluid to be tested into the cup body, laying the filter paper on the inner surface of the lid, reinstalling the lid, flipping the instrument again, so that the lid is at the bottom and the cup body is at the top, hanging the cup body, pressurizing, and starting the measurement. Each measurement process needs to be placed for 7.5 minutes or 30 minutes, and then the filtrate volume is manually read; after each measurement, the instrument needs to be flipped upside down, the lid is opened, the filter paper is taken out and thrown away, and then the cup body and the lid are cleaned, wiped, and dried, which wastes the manpower and time of engineers. In order to solve this problem, the applicant has previously submitted the following patent applications: a disposable container for water loss measurement (2019215386883), a filtration loss measurement component (2019108731972). The core of its technical solution is to use a disposable cup as an inner cup in the filtration loss process, and then cooperate with an outer cup, which can greatly reduce the workload, significantly reduce manpower consumption, reduce measurement time, and improve measurement efficiency. Among them, the outer cup is a fixed structure, and the inner cup uses a special disposable cup such as a paper cup or a plastic cup. How to realize the automatic use and recovery of the inner cup and improve the automation level of drilling fluid filtration loss detection is a difficult problem. In addition, although relatively automated titration equipment such as titrators have appeared in the prior art, they can only titrate one ion at a time, resulting in low work efficiency.

[0004] In summary, the existing drilling fluid viscosity and water analysis testing equipment all have the defects of low automation and high labor consumption. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic detection system for the comprehensive performance of drilling fluid, so as to solve the problems of low automation and high labor consumption existing in the existing drilling fluid viscosity and water analysis equipment, and achieve the purpose of reducing labor intensity and improving the automation degree of the drilling fluid performance detection process.

[0006] The present invention is realized through the following technical solutions:

[0007] An automatic detection system for the comprehensive performance of drilling fluid, comprising a viscosity measurement system and a water analysis system;

[0008] The viscosity measurement system includes a cabinet body, the cabinet body includes a lower layer, a middle layer and an upper layer. A waste liquid bucket is arranged in the lower layer, a liquid accumulation box is arranged in the middle layer, and the liquid accumulation box is connected to the waste liquid bucket through a water pipe. A workbench is arranged in the upper layer. An activity disk, a grouting assembly, a cleaning assembly and a measurement assembly are arranged on the top of the workbench. The activity disk can rotate around the center of the activity disk on the workbench. A plurality of paddle cups are arranged on the activity disk. Connecting pipes are arranged at the bottoms of the paddle cups. One end of each connecting pipe communicates with the inner bottom of the paddle cup, and the other end extends into the liquid accumulation box. Valves are arranged in the connecting pipes; the grouting assembly, the cleaning assembly and the measurement assembly are sequentially arranged outside the activity disk. The grouting assembly includes a first driving mechanism and a conduit, and the first driving mechanism can drive the conduit to insert into the paddle cup; the cleaning assembly includes a third driving mechanism and a cleaning head, and the third driving mechanism can insert the cleaning head into the paddle cup; the measurement assembly includes a fourth driving mechanism, a rotating cylinder, a fifth driving mechanism and a rotor. The fourth driving mechanism can drive the rotating cylinder to insert into the paddle cup, and the fifth driving mechanism can drive the rotating cylinder to rotate; a second slurry conveying pipe and a controller are also included. The second slurry conveying pipe is connected to the conduit, and the first driving mechanism, the third driving mechanism, the fourth driving mechanism, the fifth driving mechanism and the valve are all connected to the controller;

[0009] The water analysis system comprises an inner cup taking component, an inner cup recovery component and a filtrate detection component; the inner cup taking component comprises a positive placement station for positively overlapping inner cups, a cup taking mechanism for taking out inner cups one by one from the positive placement station, a clamping device for clamping the inner cup taken out by the cup taking mechanism, a conveying mechanism for moving the clamping device, a grouting device located on the conveying path of the conveying mechanism, and a pressurized plug located on the conveying path of the conveying mechanism; the inner cup recovery component comprises an inner cup clamp for taking the inner cup from the clamping device, a first rotating mechanism for driving the inner cup clamp to rotate along a horizontal axis, and a first rotating mechanism for driving the inner cup clamp to rotate along a horizontal axis. A second rotating mechanism for driving the inner cup clamp to rotate along the vertical axis, and a lifting component for driving the inner cup clamp to rise and fall; it also includes an inverted station, which is used for the inner cup to be inverted and overlapped; the second rotating mechanism can drive the inner cup clamp to reach the top of the inverted station; the filtrate detection component includes a filter cup for receiving the filtrate lost from the inner cup, a liquid receiving cup connected to the filter cup in sequence, a liquid taking cup, an injection pump, and a displacement mechanism, one station of the displacement mechanism is a waste liquid discharge terminal, and the other stations are connected to the titration cup; the injection pump can output liquid to different stations through the displacement mechanism.

[0010] The present application includes two major parts: a viscosity measurement system and a water analysis system. The two parts operate independently when in use. The drilling fluid only needs to be input into the paddle cup of the viscosity measurement system and the grouting device of the water analysis system respectively, and the apparent viscosity measurement, filtration loss and titration of the drilling fluid can be performed simultaneously.

[0011] When the viscosity measuring system in the present application is used, the slurry delivery pipe is connected to the drilling fluid to be measured, the drilling fluid is delivered into the conduit by the water pump on the slurry delivery pipe, and the conduit connected to the drilling fluid to be tested is inserted into the paddle cup by the first driving mechanism, so as to realize the rapid feeding of the drilling fluid to be tested, and then the movable disk is rotated to rotate the paddle cup containing the drilling fluid to be tested to the bottom of the measuring component, and the fourth driving mechanism of the measuring component inserts the rotating drum and the rotor into the paddle cup, and the fifth driving mechanism drives the rotating drum to rotate in the paddle cup, forcing the drilling fluid rotating disk in the paddle cup, and finally acts on the rotor to rotate, thereby realizing the measurement of the viscosity of the drilling fluid in the paddle cup. The principle of measuring the viscosity of the drilling fluid by rotating the rotor in the above-mentioned middle is the prior art; when the measuring component is testing the drilling fluid in the paddle cup, the grouting component is used to deliver cleaning water to the next paddle cup, and when the measurement of the drilling fluid in the paddle cup is completed, the paddle cup containing the drilling fluid rotates to the next station, and the paddle cup containing the cleaning water rotates to the bottom of the measuring component. When the cleaning water is removed from the paddle cup, the cleaning water in the paddle cup is forced to clean the paddle cup and the rotor, and the cleaning water in the paddle cup is forced to move up and down in the paddle cup during the cleaning process. The cleaning force on the rotor and the paddle cup is further increased, thereby realizing automatic and rapid cleaning of the rotor and the paddle cup in the viscosity testing equipment. After the paddle cup filled with drilling fluid is discharged into the liquid storage tank by the valve on the connecting pipe, cleaning water is injected into the paddle cup, and then the cleaning head is inserted into the paddle cup by the third driving mechanism, and the drilling fluid attached to the inner wall of the paddle cup is cleaned by the cleaning head. During the cleaning process, the waste liquid generated in the paddle cup can be discharged into the liquid storage tank through the valve in the connecting pipe, and then gathered into the waste liquid barrel, thereby completing the purpose of centralized recovery of the waste liquid generated by the measurement, realizing the centralized collection of the waste liquid generated during the cleaning process, and avoiding the random discharge of waste liquid and pollution of the environment.

[0012] The water analysis system in this application includes:

[0013] In the inner cup taking assembly, the upright placement station is used to place the inner cups in a stacked manner in the positive direction, wherein the positive direction refers to the inner cups with their open ends facing upwards and stacked in sequence. The cup taking mechanism is used to take out the inner cups one by one from the upright placement station, and transfer the inner cups to the clamping device, clamp the taken out inner cups by the clamping device, and then transport the inner cups to the next station by the conveying mechanism. This solution solves the problem that the drilling fluid loss detection operation can only be performed by manpower in the prior art, significantly reduces manpower consumption and improves the degree of automation. After the clamping mechanism clamps the inner cup, it moves to the bottom of the grouting device, and the drilling fluid to be measured is injected through the grouting device. Then the inner cup filled with drilling fluid is moved to the bottom of the pressure plug, the open end of the inner cup is blocked by the pressure plug and pressurized to achieve normal drilling fluid loss measurement.

[0014] In the inner cup recycling assembly, the inner cup clamp is used to hold the inner cup with remaining drilling fluid after fluid loss. Then, it is rotated horizontally to a proper position by the second rotating mechanism. Next, the first rotating mechanism drives the inner cup clamp to rotate vertically, making it tilt and pour out the remaining drilling fluid. After that, the second rotating mechanism is started to a proper position, and the first rotating mechanism is continuously started to drive the inner cup clamp to continue rotating vertically until the open end of the clamped inner cup faces downward. Then, the inner cup can be lowered by the lifting assembly. After the inner cup clamp holds the inner cup, the inner cup clamp can also be driven upward by the lifting assembly to stably lift the inner cup and then move it. This solution has a high degree of automation and overcomes the problem that after the fluid loss measurement assembly is used, the inner cup needs to be manually taken out, poured, and discarded. The inner cup is placed upside down with the open end facing downward, and the used inner cups can be stacked in sequence. After stacking a certain number, they can be manually recycled and processed uniformly. Therefore, this solution achieves the effect of improving the automated recycling process of the inner cup after the fluid loss process. Among them, the transmission methods between the first rotating mechanism, the second rotating mechanism, the lifting assembly, and the inner cup clamp can use any existing transmission structure, including but not limited to direct connection at the output end, indirect connection, drive by a gear train, belt and chain, etc. The lifting of the inner cup clamp can be achieved through a slide rail, guide rail, chute, motor screw, and any other existing lifting methods, such as lifting once by a cylinder, or lifting in multiple stages by two-stage or even multi-stage cylinders. Therefore, any existing transmission structure and connection method that can achieve the respective effects of the first rotating mechanism, the second rotating mechanism, and the lifting assembly should fall within the protection scope of this application.

[0015] In the filtrate detection assembly, the filter cup holds the filtrate, and the filtrate enters the liquid receiving cup for storage. When titration detection is required, the filtrate enters the liquid extraction cup from the liquid receiving cup and is pumped to different workstations by an injection pump. Among them, the position switching between the injection pump and each workstation is achieved by a position changing mechanism. Through the action of the position changing mechanism, the output direction of the injection pump faces different workstations, so that the filtrate can be injected into different titration cups according to the setting requirements. Each titration cup can perform titration detection of different ions through an existing titrator, thus achieving the effect of quickly performing titration detection of different ions. In addition, by injecting deionized water into the system and then making the output end of the injection pump face the waste liquid discharge port I through the position changing mechanism, the rapid flushing of the entire system pipeline can be achieved, thus solving the problem that only manual cleaning is possible in the prior art. In this solution, the position changing mechanism can adopt any existing technology, as long as it can switch the liquid output direction in the injection pump to different workstations. Those skilled in the art can achieve this through existing technologies, such as by moving the orientation or position of the output end of the injection pump, or moving the titration cups at each workstation to face the injection pump output port when needed.

[0016] Further, the grouting assembly further includes a first support frame and a cross plate. The first support frame is fixed on the top of the workbench, the first driving mechanism is fixed on the side wall of the first support frame, the cross plate is connected to the output end of the first driving mechanism, a connecting sleeve is provided on the cross plate and penetrates through the cross plate. A connecting rod is provided in the connecting sleeve, the connecting rod is provided with a through hole, a conduit is inserted in the through hole, and the conduit is in clearance fit with the through hole; a connecting head is provided on the side wall of the connecting sleeve, the connecting head is connected to one of the waste liquid barrels through a water pipe, and the connecting head is communicated with the through hole; a first slurry conveying pipe is further provided on the top of the workbench, one end of the first slurry conveying pipe extends into the workbench, and the other end is communicated with the top of the conduit through a hose; the first support frame is of an L-shaped structure, a first reinforcing rib and a first fixing plate are provided on the first support frame, and the first slurry conveying pipe penetrates through the first fixing plate; a cap is further included, the cap is connected to the conduit, and the connecting rod is inserted into the bottom of the cap; a sensor is further provided on the cross plate.

[0017] The grouting assembly provided in this technical solution can supply the drilling fluid required for measurement to the slurry cup. Connect the slurry conveying pipeline of the drilling fluid to be measured with the conduit. The drilling fluid to be measured flows into the slurry cup through the pipeline, achieving the purpose of feeding the slurry cup. At the same time, when it is necessary to clean the slurry cup, the provided grouting assembly can also supply cleaning liquid to the slurry cup. Since one of the waste liquid barrels is connected to the connector through a water pipe, cleaning water can be stored in this waste liquid barrel, and the other waste liquid barrel is used to collect waste liquid. The water pump on the water pipe is used to send the cleaning water stored in the waste liquid barrel into the connector. Since the clearance fit is adopted between the conduit and the through hole of the connecting rod, the water entering at the connector flows through the gap between the conduit and the through hole, flushing the measured drilling fluid attached to the outer wall of the conduit into the slurry cup. Since the conduit is inserted into the slurry cup for feeding, the outer wall of the conduit is attached with the measured drilling fluid. Therefore, in this technical solution, the provided connector can ensure that during the process of supplying cleaning water to the slurry cup, the measured drilling fluid attached to the outer wall of the conduit is flushed away together, improving the cleaning effect of the measuring equipment. At the same time, when using the slurry conveying assembly to supply cleaning water to the paddle cup, connect the slurry conveying pipe to the external tap water, and use the water pump on the slurry conveying pipe to send the cleaning water into the slurry cup through the conduit. Since a part of the drilling fluid will remain in the conduit when using the conduit to supply the drilling fluid required for measurement to the slurry cup, during the process of the conduit conveying the cleaning water, the drilling fluid remaining in the conduit can be discharged into the slurry cup, thus realizing the cleaning of the drilling fluid remaining in the pipeline. The provided first support frame is fixedly bolted to the top of the workbench, realizing the fixation between the first support frame and the workbench. The provided reinforcing rib can improve the strength of the first support frame and extend its service life. Since the clearance fit is adopted between the conduit and the connecting rod, in order to prevent the cleaning water entering the connecting rod and the conduit from leaking from the top, a cover is provided to seal the connection at the top of the connecting rod and the conduit, preventing the cleaning water from leaking from the top of the connecting rod. The provided sensor is used to detect the volume of the drilling fluid or cleaning liquid to be measured conveyed into the paddle cup.

[0018] Furthermore, the cleaning component further includes a second support frame, a second driving mechanism, and a first connecting plate in an L shape. The second support frame is in an L shape and is fixed to the top of the workbench. The second support frame is provided with second reinforcing ribs. The third driving mechanism is fixed to the second support frame. The output end of the third driving mechanism is connected to the first connecting plate. A support plate in an L shape is provided on the side wall of the first connecting plate. The second driving mechanism is fixed to the support plate, and a spray head is provided on the support plate. The cleaning head includes a cleaning rod and a plurality of brushes. The output end of the second driving mechanism is connected to the cleaning rod. The brushes are located on the circumferential outer wall of the cleaning rod, and the brushes are spirally distributed on the outer wall of the cleaning rod. In this solution, the second support frame provided is fixed to the top of the workbench by bolts. The second reinforcing ribs improve the strength of the second support frame. The second driving mechanism provided is a motor, which can drive the cleaning rod to rotate during operation. The third driving mechanism is a hydraulic cylinder. During operation, the output end of the third driving mechanism drives the first connecting plate to move in the vertical direction, thereby driving the cleaning rod to insert into or extend out of the paddle cup. The spray head provided is connected to a waste liquid bucket filled with cleaning water through a water pipe, and can transport the cleaning water stored in the waste liquid bucket into the paddle cup to provide the required cleaning water for cleaning the inner wall of the paddle cup. When using the cleaning component to clean the impurities on the inner wall of the paddle cup, the third driving mechanism is used to insert the cleaning head into the paddle cup, and then the second driving mechanism drives the cleaning rod to rotate. During the rotation of the cleaning rod, the brushes provided on the outer wall of the cleaning rod act on the inner wall of the paddle cup to brush off the impurities attached to the inner wall of the paddle cup, thereby achieving the purpose of cleaning the paddle cup.

[0019] Furthermore, the measuring component further includes a torque detector and a third support frame. The third support frame is fixed to the workbench. The fourth driving mechanism is fixed to the side wall of the third support frame. A moving plate is provided at the output end of the fourth driving mechanism. A support plate and a correction box are provided on the moving plate. The fifth driving mechanism is located on the support plate. A fixed cylinder is also provided on the support plate. A rotating cylinder is located inside the fixed cylinder. A transmission belt is also provided at the output end of the driving driving mechanism, and the transmission belt is connected to the rotating cylinder. A connecting block is provided inside the correction box, and the connecting block can move on the moving plate. A convex block is provided on the connecting block, and an installation sleeve is provided inside the convex block. A first spring is provided inside the installation sleeve. Two pressing sleeves are provided on the first spring. One of the pressing sleeves is connected to the torque detector, and an adjusting nut is provided on the other pressing sleeve. The torque detector is connected to the rotor. Two second sliding platforms are also provided on the side wall of the fourth driving mechanism. Two second sliding grooves matching the second sliding platforms are provided on the moving plate, and the second sliding platforms are located inside the second sliding grooves. A first sliding platform is also provided on the side wall of the moving plate. A first sliding groove matching the first sliding platform is also provided on the connecting block, and the first sliding platform is located inside the first sliding groove. Fixed bolts are provided on both sides of the connecting block, and the fixed bolts can fix the connecting block on the first sliding platform.

[0020] When this solution measures viscosity, the paddle cup containing the material to be measured is placed below the rotating cylinder. The driving mechanism drives the moving plate to move downward in the vertical direction, so that the rotating cylinder is inserted into the paddle cup filled with liquid. Then, adjust the position of the connecting block on the moving plate to make the rotor extend into the rotating cylinder. Finally, the fifth driving mechanism works to drive the rotating cylinder to rotate, so that the liquid to be measured placed in the paddle cup also rotates accordingly, driving the rotor to rotate. When the rotor rotates by a certain angle, the torque detector can accurately measure the torque value generated by the liquid to be tested during the rotation of the rotor. Then, the viscosity of the material to be tested can be calculated from the torque value. The principle of measuring the torque value of the rotor rotation using the torque detector is prior art, thus realizing the measurement of the viscosity of the material in the paddle cup. At the same time, the support plate covers the paddle cup to ensure that the material in the paddle cup is not easily splashed out during rotation; when it is necessary to calibrate the first spring in the equipment, use a steel wire rope to hang the weight on the rotor. Since the pressing sleeve on the adjusting nut is connected to the coils of the first spring, that is, the inner wall of the pressing sleeve is provided with spiral grooves matching the first spring, and the first spring is located in the spiral grooves of the pressing sleeve. When the pressing sleeve is rotated, the first spring can move within the pressing sleeve. Therefore, when the adjusting nut is rotated, the pressing sleeve will move on the coils of the first spring, thereby changing the stretched or compressed length of the first spring, and adjusting the elastic force of the first spring acting on the rotor to be within the specified error range. In this solution, only by rotating the adjusting nut can the stretching amount of the first spring be quickly adjusted, realizing the calibration of the first spring.

[0021] When the fourth driving mechanism is working, it can drive the moving plate to move along the vertical direction, and the second sliding groove on the moving plate is connected to the second sliding table on the driving mechanism, ensuring that the moving plate can move along the second sliding table during movement, improving the accuracy of the moving plate movement and preventing the moving plate from skewing during movement; the provided first sliding table and second sliding groove are used to guide the connecting block, ensuring that the connecting block can move on the moving plate along the direction of the first sliding table, so as to ensure that the rotor below the connecting block can accurately enter the rotating cylinder; and the provided fixing bolt is used to stably fix the connecting block on the first sliding table. When it is necessary to insert the rotor into the rotating cylinder, loosen the fixing bolt and move the moving block along the first sliding table, so that the rotor can be smoothly inserted into the rotating cylinder. Finally, tighten the fixing bolt so that the fixing bolt acts on the first sliding table, thereby stably fixing the connecting block on the first sliding table. The opening provided on the convex block is used to place the adjusting nut, enabling the adjusting nut to rotate within the opening.

[0022] Preferably, a convex edge is provided at the port of the rotating cylinder, and the diameter of the convex edge is larger than that of the fixed cylinder, so that the rotating cylinder can be placed inside the fixed cylinder. The fixed cylinder is used to limit the rotating cylinder to ensure that the rotating cylinder can rotate within the fixed sleeve. The transmission belt provided at the output end of the fifth driving mechanism is sleeved on the rotating cylinder. When the fifth driving mechanism works, the fifth driving mechanism drives the transmission belt to rotate, and the transmission belt drives the rotating cylinder to rotate, thereby realizing the rotation of the rotating cylinder.

[0023] Furthermore, the cabinet body includes a plurality of support rods and connecting members. The cross-section of the support rod is a rectangular structure, and connecting grooves are provided on the four side walls of the support rod. The connecting grooves are distributed along the long axis direction of the support rod, and both ends of the connecting grooves communicate with both ends of the support rod. The connecting member includes a first connecting rod, a second connecting rod, and a slider. One end of the first connecting rod is perpendicularly connected to the second connecting rod to form a T-shaped structure, and the other end is connected to the slider. Both the first connecting rod and the second connecting rod are located inside the support rod, and the slider is located on the end face of the support rod. The support rod and the connecting member form a rectangular frame. A plurality of second fixing plates are provided on the inner bottom of the frame, and a placement rack is provided between adjacent two second fixing plates. The waste liquid bucket is located inside the placement rack. Roller assemblies are further provided at the four corners of the bottom of the frame. The roller assembly includes a top plate, a frame body, and a roller. The cross-section of the top plate is triangular, and the top plate is connected to the bottom of the support rod. The frame body is connected to the top plate, and the roller is located on the frame body. The roller assembly further includes a movable rod and a brake disc. The top of the movable rod is rotatably connected to the top plate, and the brake disc is connected to the movable rod by a thread and is located inside the frame body. An opening is provided on the side wall of the brake disc facing the roller direction, and the roller is located inside the opening.

[0024] The interior of the cabinet body in this solution is a frame structure. The adjacent support rods are connected in the connecting grooves through the connecting members to realize the assembly between adjacent two support rods, which is convenient for the quick loading and unloading of the cabinet body. The overall shape of the provided connecting member is a T-shaped structure. The first connecting rod and the second connecting rod of the connecting member are both embedded inside the support rod to ensure that the first connecting rod and the second connecting rod can be stably fixed inside the support rod. The slider connected to the first connecting rod extends to the end face of the support rod to ensure that the slider can be connected to the connecting groove on the support rod. Since the connecting grooves with a T-shaped cross-section are provided on the four side walls of the support rod, when connecting adjacent support rods, since the connecting grooves communicate with the end face of the support rod, the slider can be inserted into the connecting groove from the end face of the support rod to realize the connection between the two support rods, and finally form a rectangular frame structure.

[0025] The provided top plate is used to connect with the two support plates at the bottom of the frame. Bolts are used to connect the top plate with the adjacent two support rods respectively, ensuring that roller assemblies are installed at the four corners of the bottom of the rectangular cabinet. The rollers arranged inside the frame can rotate within the frame. When it is necessary to transfer the cabinet, the rollers provided at the four corners of the bottom can be used to move the support frame, thereby pushing the waste liquid barrel to the sewage treatment site, saving labor. A bearing is provided at the top of the provided movable rod, and the bearing is connected to the top plate, enabling the movable rod to rotate within the top plate. Since the movable rod is connected to the brake disc through threads, when the movable rod rotates under the top plate, the brake disc can move along the vertical direction as the movable rod moves, to adjust the height of the brake disc. When the brake disc moves to be flush with the ground, the friction force between the brake disc and the ground can be used to fix the rollers on the ground, preventing the rollers from moving on the ground by themselves, thereby ensuring that the support frame can be stably fixed on the ground. During the process of the brake disc moving along the vertical direction, the opening provided on the brake disc ensures that the rollers can smoothly pass through the opening, avoiding interference between the brake disc and the rollers.

[0026] Further, a pallet is provided inside the middle layer. The liquid accumulation tank is located on the pallet. A number of vertical rods are also provided on the pallet, and the vertical rods are connected to the top of the workbench by bolts. A rotating rod is further provided inside the liquid accumulation tank. A sixth driving mechanism is provided at the bottom of the rotating rod. A connecting ring is also provided at the top of the rotating rod, and the connecting ring is connected to the bottom of the movable disk by a fixing bolt. A number of bearing members equal to the number of paddle cups are provided below the workbench, and the bearing members are connected to the movable disk by bolts. The connecting pipe is fixed on the bearing members. A placement hole matching the rotating rod is also provided inside the liquid accumulation tank, and the rotating rod is inserted into the placement hole. A flow channel is formed between the placement hole and the inner wall of the liquid accumulation tank, and the depth of the flow channel increases successively. A water outlet pipe is provided at the bottom of the liquid accumulation tank, and the water outlet pipe is connected to the waste liquid bucket. A buffer assembly is further provided between the second fixing plate and the placement rack. The buffer assembly includes a first buffer layer, a second buffer layer, and a third buffer layer. The cross-sections of the first buffer layer, the second buffer layer, and the third buffer layer are all U-shaped structures. The first buffer layer is located in the U-shaped groove of the second buffer layer, and the second buffer layer is located in the U-shaped groove of the third buffer layer. The provided sixth drive is used to drive the rotation of the movable disk, so as to move the paddle cup to different workstations for work. The provided placement hole ensures that there is space in the liquid accumulation tank for placing the rotating rod, and the provided flow channel facilitates the waste liquid flowing out of the connecting pipe to flow in the flow channel. And because the water outlet pipe is connected to the deepest part of the flow channel, the waste liquid flows along the flow channel to the water outlet pipe, and finally the waste liquid is stored in the waste liquid bucket, thus realizing the centralized collection of the waste liquid. The provided buffer assembly can play a certain buffering role in the waste liquid bucket between two adjacent fixing plates, ensuring that the waste liquid bucket on the support frame can reduce the shaking of the waste liquid bucket during handling, thereby effectively avoiding the leakage of the waste liquid in the waste liquid bucket. The buffer assembly is composed of a first buffer layer, a second buffer layer, and a third buffer layer, and the first buffer layer, the second buffer layer, and the third buffer layer are all made of rubber material, having a certain buffering effect. Preferably, the conveying mechanism is a guide rail, and the clamping device can move on the guide rail. After the clamping mechanism clamps the inner cup, it can move on the guide rail to convey the inner cup to other workstations.

[0027] Further, the upright placement station is a square frame with an open top surface and one side surface. An inner cup pressing assembly is further included opposite to the upright placement station. The inner cup pressing assembly is used to press the inner cup below. The inner cup pressing assembly includes two pressing plates that can be opened and closed, and the inner cup pressing assembly is driven by a first lifting mechanism to lift and lower. The cup picking mechanism includes a suction cup with an opening facing downwards, an air extraction pipe connected to the suction cup, a swing arm for driving the rotation of the air extraction pipe, and a second lifting mechanism for driving the lifting and lowering of the swing arm. The inner cup pressing plug is clamped by a lifting claw. A cup holder is provided below the clamping device. An outer cup matching the inner cup is provided on the cup holder. The cup holder is connected to the clamping device by a second spring. A liquid outlet is provided at the bottom of the cup holder. The filter cup is placed below the liquid outlet.

[0028] Among them, the area formed by surrounding the square frame is used to limit the stacked inner cups. Its top opening is convenient for the cup-taking mechanism to perform cup-taking operations, and its one-side opening is convenient for the whole to put in a group of overlapping inner cups. The cup-taking mechanism takes out the inner cups one by one. Since the inner cups are stacked upright, it is most convenient to take them out one by one from above. For this reason, an inner cup pressing component is provided to press the lower inner cups, so as to ensure that each time the cup-taking mechanism takes out, only the uppermost inner cup is taken out, avoiding taking out extra inner cups and causing waste. The inner cup pressing component moves from top to bottom on the first lifting mechanism. The inner cup pressing component can be configured with an induction device for sensing the top flange of the inner cup. When the inner cup flange is sensed, the two pressing plates can be closed, so that the two pressing plates are located below the top flange of the first inner cup, thereby limiting all the lower inner cups and preventing them from being lifted by the first inner cup. Among them, the opening and closing between the two pressing plates can be realized by any existing technology, and those skilled in the art can all realize it. For example, it can be realized by driving through an opening and closing motor, a cylinder, etc., so it will not be elaborated here.

[0029] When this solution works, first, the second lifting mechanism raises the height to ensure that the bottom of the suction cup is higher than the highest position of the stacked inner cups. Then, the swing arm is rotated to drive the suction cup and the suction pipe to move above the upright working position. The second lifting mechanism drives the suction cup to move downward, and the suction cup extends into the uppermost inner cup and abuts against the bottom surface of the inner cup. Then, air is pumped through the suction pipe to make the suction cup adsorb the uppermost inner cup, and then the second lifting mechanism drives the suction cup to move upward to lift the uppermost inner cup; afterwards, the swing arm rotates back to rotate the inner cup above the clamping device, and the second lifting mechanism drives it downward again to place the inner cup on the clamping device, and then the suction cup is depressurized.

[0030] The lifting claw clamps the inner cup pressure plug. When the inner cup moves to directly below it, the lifting claw descends to press the inner cup pressure plug into the inner cup filled with drilling fluid. In this solution, a cup holder is provided below the clamping device, and an outer cup matching the inner cup is provided on the cup holder, so that the inner cup can be directly placed into the outer cup, improving the stability during the filtration loss detection process. In addition, the cup holder and the clamping device are connected by a spring to improve the seismic resistance and reduce the external vibration interference. A liquid outlet is provided at the bottom of the cup holder to facilitate matching with the liquid outlet of the outer cup and facilitate the collection of the filtrate below it.

[0031] Furthermore, the inner cup clamp includes two clamping plates that can be opened and closed; the second rotating mechanism drives the inner cup clamp, the first rotating mechanism, and the lifting assembly to rotate synchronously; it also includes a water sink, and the second rotating mechanism can drive the inner cup clamp to pass over the water sink; the second rotating mechanism drives the mounting base to rotate, and a second connecting plate is provided on the mounting base, the first rotating mechanism is installed on the second connecting plate, and the output end of the first rotating mechanism is connected to the inner cup clamp; the lifting assembly is used to drive the second connecting plate to rise and fall on the mounting base.

[0032] The inner cup clamp can be equipped with a sensing device for sensing the inner cup. When the inner cup is sensed, the two clamping plates can be closed to clamp the inner cup. The opening and closing of the two clamping plates can be achieved by any existing technology, and can be achieved by those skilled in the art, such as by driving an opening and closing motor, a cylinder, etc., so it will not be described here. When the second rotating mechanism is working, it drives the inner cup clamp, the first rotating mechanism, and the lifting assembly to rotate synchronously; when the second rotating mechanism drives the inner cup clamp to the top of the sink, the second rotating mechanism is paused, and the first rotating mechanism is started at this time to tilt the inner cup and pour the remaining drilling fluid in the inner cup into the sink.

[0033] In this solution, the second rotating mechanism works to drive the mounting seat to rotate in the horizontal direction. Since the connecting plate is arranged on the mounting seat, the connecting plate rotates synchronously. Since the first rotating mechanism is installed on the connecting plate, the output end of the first rotating mechanism is connected to the inner cup clamp, so the first rotating mechanism, the inner cup clamp and the clamped inner cup can be horizontally rotated together. Preferably, the connecting plate and the mounting seat are slidably matched, such as through guide rails, slide grooves, etc. The lifting assembly drives the connecting plate to rise and fall on the mounting seat, thereby driving the first rotating mechanism and the inner cup clamp to rise and fall synchronously.

[0034] Preferably, the displacement mechanism is a turntable or a linear guide rail. The titration cup includes a calcium ion titration cup and / or a chloride ion titration cup.

[0035] Further, a liquid level sensor is provided inside the liquid receiving cup, and a pH detection sensor is provided inside the liquid extraction cup. A peristaltic pump 1 is connected between the liquid receiving cup and the liquid extraction cup; a three-way valve 1 and a three-way valve 2 are sequentially connected between the liquid extraction cup and the injection pump; the three-way valve 1 is connected to the liquid extraction cup, the three-way valve 2, and the peristaltic pump 2; the three-way valve 2 is connected to the three-way valve 1, the injection pump, and the displacement mechanism; the output end of the peristaltic pump 2 is the waste liquid discharge end 2; a peristaltic pump 3 for injecting deionized water into the liquid receiving cup is further included; each titration cup is provided with a matching titrator, a reagent addition pipeline, and a deionized water injection pipeline; peristaltic pumps 4 are provided on both the reagent addition pipeline and the deionized water injection pipeline; each titration cup is provided with a drain pipe, and a peristaltic pump 5 is provided on the drain pipe; a stirrer is provided inside each titration cup. The liquid level sensor is used to monitor the liquid level height inside the liquid receiving cup, so as to detect whether the filtrate overflows. The pH detection sensor is used to detect the pH value of the filtrate inside the liquid extraction cup. A peristaltic pump 1 is connected between the liquid receiving cup and the liquid extraction cup, and the peristaltic pump 1 is used to pump the filtrate from the liquid receiving cup to the liquid extraction cup. Among them, the peristaltic pump 2 is used to drain the waste liquid or the excess filtrate. The number of reagent addition pipelines can be set to any number according to needs, and each pipeline injects a kind of reagent respectively to avoid cross-contamination. The deionized water injection pipeline is used to inject deionized water after the titration is completed, so as to clean the titration cup. After the titration process is completed, the waste liquid in the titration cup is drained from the drain pipe through the peristaltic pump 5.

[0036] Further, the liquid receiving cup and the liquid extraction cup are connected by a hose with an inner diameter less than or equal to 2 mm. A liquid detection sensor is provided outside the hose, and the liquid detection sensor can sense the liquid inside the hose; a timing module is further included, and the output end of the liquid sensing device is connected to the input end of the timing module; liquid detection sensors are also provided on the connecting pipelines between the liquid extraction cup and the injection pump and between the injection pump and the displacement mechanism.

[0037] The inner diameter of the hose is less than or equal to 2 mm. When used to absorb a small amount of filtrate, it can effectively increase the pumping duration, thereby reducing the metering error. In this solution, a liquid detection sensor is set outside the hose to sense the liquid inside the hose. Any existing sensing device capable of sensing liquid can be used for the liquid detection sensor. When there is liquid flowing through the hose, the liquid detection sensor senses the liquid and starts sending a signal to the timing module; when there is no longer liquid flowing through the hose, the liquid detection sensor stops sending a signal to the timing module. The timing module starts timing from the moment it receives the signal and ends timing when the signal stops, so as to accurately measure the pumping duration. In this solution, a hose with a very small inner diameter is used to extend the pumping time and reduce the timing error. By means of an external liquid detection sensor and in cooperation with the timing module, the accurate measurement of the pumping duration is achieved, thereby assisting in the automatic measurement of the mud filtration loss. The timing module in this solution can be implemented using an existing timing module. Liquid detection sensors are also provided on the connecting pipelines between the liquid collection cup and the injection pump and between the injection pump and the displacement mechanism. This is convenient for detecting whether there is liquid passing through the corresponding pipelines, thereby providing a signal reference for the normal operation of the system for the staff and ensuring timely detection in case of pipeline blockage or corresponding peristaltic pump failure.

[0038] Preferably, the liquid detection sensor is a capacitive sensor attached to the pipe wall. The capacitive sensor has high sensitivity and can be immediately sensed when there is filtrate passing through the hose. High sensitivity is beneficial to further improve the timing accuracy of this application.

[0039] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0040] 1. The automatic detection system for the comprehensive performance of drilling fluid of the present invention uses the grouting component of the viscosity measurement system to not only provide the drilling fluid required for detection for the paddle cup, but also provide the cleaning water required for cleaning the paddle cup. And during the process of introducing the cleaning water, by using the structure of the clearance fit between the conduit and the connecting rod, the drilling fluid attached to the outer wall of the conduit can be effectively washed away, thereby improving the cleaning effect;

[0041] 2. In the automatic detection system for the comprehensive performance of drilling fluid of the present invention, after the measurement component in the viscosity measurement system completes the measurement of the viscosity of the drilling fluid, the grouting component is used to transport the cleaning water to the paddle cup, and it is rotated to the position of the measurement component. The fourth driving mechanism is used to insert the rotating shaft and the rotating cylinder into the paddle cup filled with cleaning water, and the fifth driving mechanism is used to rotate, forcing the cleaning water to clean the mud attached to the rotor and the rotating cylinder, achieving the purpose of automatically cleaning the rotating shaft and the rotating cylinder;

[0042] 3. The automatic detection system for comprehensive properties of drilling fluid of the present invention, in the viscosity measurement system, the fourth driving mechanism is used to quickly insert the drum into the paddle cup containing the material, and then the rotor is inserted into the drum, and the fifth driving mechanism is used to drive the drum to rotate, forcing the material in the paddle cup to drive the rotor to rotate, and finally the torque detector is used to detect the viscosity of the material, thereby realizing the rapid measurement of the viscosity of the material, and the support plate is used to cover the paddle cup to prevent the material in the paddle cup from splashing out;

[0043] 4. In the automatic detection system for comprehensive properties of drilling fluid of the present invention, after the drilling fluid contained in the paddle cup in the viscosity measuring system is measured, the drilling fluid is discharged into the liquid storage tank through the connecting pipe at the bottom of the paddle cup, and finally flows into the waste liquid barrel, thereby realizing the recycling of the drilling fluid. At the same time, the waste liquid generated during the cleaning process of the paddle cup can also be centrally stored in the waste liquid barrel, thereby realizing the centralized recycling of the waste liquid and avoiding the waste liquid from polluting the environment.

[0044] 5. The automatic detection system for comprehensive properties of drilling fluid and the water analysis system of the present invention solve the problem that the drilling fluid loss detection operation can only be performed by manpower in the prior art, and realizes the automatic use of the inner cup, which significantly reduces manpower consumption and improves the degree of automation. The water analysis system has a high degree of automation, which overcomes the problem that after the use of the loss measurement component, the inner cup needs to be manually taken out and dumped and discarded. The inner cup is placed upside down with the open end facing down, and the used inner cups can be stacked in sequence. After a certain number of stacks are reached, they can be manually uniformly recycled and processed, thereby achieving the effect of improving the automatic recycling of the inner cup after the loss process is completed.

[0045] 6. In the automatic detection system for comprehensive properties of drilling fluid of the present invention, the position switching between the injection pump and each station in the water analysis system is realized by a shifting mechanism. Through the action of the shifting mechanism, the output direction of the injection pump can be directed toward different stations, so that the filtrate can be injected into different titration cups according to the set requirements. Each titration cup can perform titration detection of different ions through an existing titrator, thereby achieving the effect of rapid titration detection of different ions.

[0046] 7. In the automatic detection system for comprehensive properties of drilling fluid of the present invention, deionized water is injected into the water analysis system, and the output end of the injection pump is directed toward the waste liquid discharge end through the displacement mechanism, so that the entire system pipeline can be quickly flushed, thereby solving the problem that the existing technology can only be cleaned manually. The deionized water injection pipeline is used to inject deionized water after the titration is completed, so as to automatically clean the titration cup. BRIEF DESCRIPTION OF THE DRAWINGS

[0095] The comprehensive performance automatic detection system for drilling fluid. On the basis of any of the above embodiments, in the water analysis system:

[0096] The upright placement station 89 is a square structure formed by surrounding three plates. It further includes an inner cup pressing and holding assembly facing the upright placement station 89, and the inner cup pressing and holding assembly is used to press the inner cup below. The inner cup pressing and holding assembly includes two pressing plates 91 that can be opened and closed, and the inner cup pressing and holding assembly is driven by a first lifting mechanism 92 to lift. The cup picking mechanism includes a suction cup 93 with an opening facing downwards, an air suction pipe 94 connected to the suction cup 93, a swing arm 95 for driving the air suction pipe 94 to rotate, and a second lifting mechanism 96 for driving the swing arm 95 to lift. The conveying mechanism is a guide rail 97, and the clamping device 90 can move on the guide rail 97. It further includes a grouting device 98. When the clamping device 90 moves on the guide rail 97, it can pass directly below the grouting device 98. It further includes an inner cup pressurizing plug 99. When the clamping device 90 moves on the guide rail 97, it can pass directly below the inner cup pressurizing plug 99. The inner cup pressurizing plug 99 is clamped by a lifting claw 100.

[0097] Preferably, a cup holder 101 is arranged below the clamping device 90. The cup holder 101 is connected to the clamping device 90 through a second spring 102. A liquid outlet 103 is arranged at the bottom of the cup holder 101, and an outer cup 132 is fixed on the cup holder 101.

[0098] When this embodiment works, first, the height is lifted by the second lifting mechanism to ensure that the bottom of the suction cup is higher than the highest position of the stacked inner cups. Then, the swing arm is rotated to drive the suction cup and the suction pipe to move above the upright working station. The second lifting mechanism drives the suction cup to move downward. The suction cup extends into the topmost inner cup and abuts against the bottom surface of the inner cup. Then, air is pumped through the suction pipe to make the suction cup adsorb the topmost inner cup. Then, the second lifting mechanism drives the suction cup to move upward to lift the topmost inner cup. After that, the swing arm rotates to turn the inner cup above the clamping device. The second lifting mechanism then drives it to move downward and places the inner cup on the clamping device 90. The suction cup is depressurized. The clamping device 90 moves on the guide rail to the grouting device 98 to inject drilling fluid, and then continues to move below the pressure plug 11, which is blocked by the pressure plug 11 for filtration loss detection. After the detection is completed, it continues to move to the inner cup fixture 104 through the guide rail. The inner cup fixture 104 recovers the inner cup with remaining drilling fluid. At the same time, the filtrate detection component titrates the obtained filtrate.

[0099] Embodiment 6:

[0100] For the automatic detection system of the comprehensive performance of drilling fluid, on the basis of any of the above embodiments, in the water analysis system:

[0101] The second rotating mechanism 106 drives the inner cup fixture 104, the first rotating mechanism 105, and the lifting assembly 108 to rotate synchronously. The second rotating mechanism 106 drives the mounting seat 107 to rotate. A second connecting plate 109 is arranged on the mounting seat 107. The first rotating mechanism 105 is installed on the second connecting plate 109, and the output end of the first rotating mechanism 105 is connected to the inner cup fixture 104. The lifting assembly 108 is used to drive the second connecting plate 109 to lift on the mounting seat 107. It further includes a water tank 110. The second rotating mechanism 106 can drive the inner cup fixture 104 to pass above the water tank 110. It further includes an inverted position 111 for overlapping the inner cups in an inverted manner. The second rotating mechanism 106 can drive the inner cup fixture 104 to reach directly above the inverted position 111. It further includes a guide rail 97 and a clamping device 90 that can move on the guide rail 97. The guide rail 97 and the inverted position 111 are located on opposite sides of the inner cup fixture 104.

[0102] The specific working process of the inner cup recovery component in this embodiment is as follows:

[0103] After the filtration loss detection is completed, the clamping device 90 clamps the inner cup. The inner cup containing the remaining drilling fluid is moved to the position where the inner cup fixture 104 is located through the guide rail 97. The inner cup fixture 104 clamps the inner cup, and the clamping device 90 is released. It is rotated 90° in the horizontal direction through the second rotating mechanism 106 to above the water tank 110. Then, the inner cup fixture is driven to rotate 100°-110° in the vertical direction through the first rotating mechanism 105 to make it inclined, and the remaining drilling fluid in it is poured out. After that, the second rotating mechanism is started again to continue rotating it 90° in the horizontal direction to above the inverted position 111. The first rotating mechanism 105 is continuously started to drive the inner cup fixture 104 to continue rotating in the vertical direction until the open end of the clamped inner cup faces downward, and the inner cup can be lowered through the lifting assembly.

[0104] Preferably, after the inner cup fixture clamps the inner cup, the inner cup fixture can also be driven to move upward through the lifting assembly, so as to stably lift the inner cup and then move it.

[0105] Embodiment 7:

[0106] For the automatic detection system for the comprehensive performance of drilling fluid, on the basis of any of the above embodiments, in the water analysis system:

[0107] A liquid level sensor 114 is arranged in the liquid receiving cup 113, a pH detection sensor 117 is arranged in the liquid sampling cup 116, and a peristaltic pump 121 is connected between the liquid receiving cup 113 and the liquid sampling cup 116. A three-way valve 122 and a three-way valve 123 are sequentially connected between the liquid sampling cup 116 and the syringe pump 118; the three-way valve 122 is connected to the liquid sampling cup 116, the three-way valve 123, and the peristaltic pump 124; the three-way valve 123 is connected to the three-way valve 122, the syringe pump 118, and the displacement mechanism. The output end of the peristaltic pump 124 is the waste liquid discharge end 125; a peristaltic pump 115 for injecting deionized water into the liquid receiving cup 113 is also included. The displacement mechanism is a turntable or a linear guide rail. The titration cup 120 includes a calcium ion titration cup and a chloride ion titration cup. Each titration cup 120 is provided with a matching titrator 126, a reagent addition pipeline, and a deionized water injection pipeline; peristaltic pumps 127 are arranged on both the reagent addition pipeline and the deionized water injection pipeline. Each titration cup 120 is provided with a drain pipe 128, and a peristaltic pump 129 is arranged on the drain pipe 128. A stirrer 130 is arranged in each titration cup 120.

[0108] The liquid receiving cup 113 and the liquid sampling cup 116 are connected by a hose with an inner diameter less than or equal to 2 mm. A liquid detection sensor 131 is arranged outside the hose, and the liquid detection sensor 131 can sense the liquid in the hose; a timing module is also included, and the output end of the liquid sensing device 4 is connected to the input end of the timing module.

[0109] In this embodiment, a liquid detection sensor is arranged outside the hose to sense the liquid in the hose. Any existing induction device capable of sensing liquid can be used as the liquid detection sensor. When liquid flows through the hose, the liquid detection sensor senses the liquid and starts sending a signal to the timing module. When there is no longer liquid flowing through the hose, the liquid detection sensor stops sending a signal to the timing module. The timing module starts timing when it receives the signal and ends timing when the signal stops, so as to accurately measure the pumping duration. In this solution, a hose with a very small inner diameter is used to extend the pumping time and reduce the timing error. By means of an external liquid detection sensor and in cooperation with the timing module, the accurate measurement of the pumping duration is achieved, thereby assisting the automatic measurement of the mud filtration loss. A liquid detection sensor 131 is also arranged on the connecting pipeline between the liquid collection cup 116 and the injection pump 118 and between the injection pump 118 and the displacement mechanism.

[0110] The process of filtrate titration detection in this embodiment is as follows:

[0111] First, the filter cup 112 drips liquid for 30 minutes, and the liquid collection cup 113 with a capacity of 50 ml stores the liquid. The liquid level sensor 114 detects the liquid level height in the liquid collection cup 113. If the filtrate overflows, an alarm is issued. When starting the titration detection, the peristaltic pump 121 transports the filtrate to the liquid collection cup 116 with a capacity of 50 ml. During the transportation process, the liquid detection sensor 131 between the liquid collection cup 113 and the liquid collection cup 116 works. The liquid signal starts timing from no to yes and ends timing from yes to no, so that the total amount of filtrate can be calculated through the duration and the displacement. After that, the filtrate passes through the three-way valve 122 and the three-way valve 123, and the injection pump 118 injects the filtrate into the titration cups 120 at each titration station in sequence through the displacement mechanism, and the titrators 126 corresponding to the respective titration cups 120 perform the titration detection of the contents of different ions. After the titration detection is completed, the peristaltic pump 115 injects deionized water into the liquid collection cup 113. The deionized water rinses the liquid collection cup 113 and is discharged from the waste liquid discharge end 2 through the peristaltic pump 121, the liquid collection cup 116, the three-way valve 122, and the peristaltic pump 124. This cleaning step is repeated 3 times. In addition, the deionized water injection pipelines corresponding to the respective titration cups 120 inject deionized water into the respective titration cups 120 for rinsing. After being stirred and cleaned by the stirrer 130, the waste water is drained away from the respective drain pipes 128 by the peristaltic pump 129. This cleaning step is repeated 4 times.

[0112] Preferably, in this embodiment, the titration process of the calcium ion titration cup is as follows: The injection pump 118 adds 1 ml of filtrate into it. Two reagent addition pipelines respectively add 10 ml of NaOH solution and 1 ml of masking agent into it through two peristaltic pumps, and 60 ml of deionized water is injected through the corresponding deionized water injection pipeline. Then, the corresponding titrator 126 drops the EDTA solution through the built-in titration injection pump for titration detection. Preferably, in this embodiment, the titration process of the chloride ion titration cup is as follows: The injection pump 118 adds 1 ml of filtrate into it. One reagent addition pipeline adds 10 ml of masking agent such as dilute nitric acid solution into it through a peristaltic pump, and 60 ml of deionized water is injected through the corresponding deionized water injection pipeline. Then, the corresponding titrator 126 drops the silver nitrate solution through the built-in titration injection pump for titration detection.

[0113] Of course, in addition to the valves and pipelines disclosed in this embodiment, those skilled in the art can add various required pipelines and valves on the basis of this embodiment according to actual needs when implementing the filtrate detection assembly.

It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention.
