[0002] Liquid concentration refers to the amount of solute contained in a unit volume of solution. The measurement of liquid concentration is of great importance in industrial production, directly affecting production processes, reagent ratios, parameter control, safety factors, economic benefits, and other major aspects.
[0003] Common concentration meters include X-ray concentration meters, ultrasonic concentration meters, photoelectric concentration meters, and differential pressure concentration meters. X-ray concentration meters pose risks of environmental pollution and safety hazards due to the presence of radioactive sources. Ultrasonic concentration meters are affected by air bubbles; excessive air bubbles can affect the accuracy of the measurement results. Photoelectric concentration meters have a small measurement range and are greatly affected by color, making them suitable only for low-concentration, well-suspended solutions. Differential pressure concentration meters require a difference between the density of the medium and the density of water. They are inaccurate at low concentrations and are easily affected by flow and other impacts. Gravimetric concentration measurements are complex and discontinuous, especially when the solute has poor solubility or suspension and large particle size (e.g., slurries in coal, various non-metallic minerals, and non-ferrous metal ore washing and processing). In these cases, it is difficult to accurately measure concentration values using these methods.

[0016] The present invention achieves the following technical advantages over the prior art: 1. In the mixed slurry concentration detection device of this utility model, a measuring tank is suspended inside the measuring chamber. When detecting the concentration of the mixed slurry, the mixed slurry to be tested is fed in through a feeding mechanism. After the mixed slurry is filled, the weight data is obtained through a weighing sensor. Combined with the density of the mixed slurry and the volume of the measuring tank, the concentration value of the slurry can be calculated. The entire measurement process is rapid and the concentration detection accuracy is high. Compared with photoelectric concentration meters, differential pressure concentration meters, ultrasonic concentration meters, and X-ray concentration meters, it is not affected by the particle size of the slurry.

[0017] 2. In the mixed slurry concentration detection device of this utility model, a vibration damper is set at the bearing end of the weighing sensor. When the mixed slurry is fed into the measuring barrel, the up-and-down vibration generated by the barrel is transmitted to the pull rod of the vibration damper through the suspension. Under the action of the piston and spring, the vibration of the measuring barrel is converted into the up-and-down movement of the piston. The spring will continuously stretch and contract, realizing mechanical consumption of vibration energy. At the same time, the piston will continuously compress and release the gas in the cylinder, realizing work to consume vibration energy. The continuous up-and-down movement of the piston will drive the permanent magnet and the spiral coil to continuously cut the magnetic field lines, thereby generating current and converting vibration energy into electrical energy. This forms a three-way energy consumption: mechanical energy consumption, compressed gas energy consumption, and vibration energy conversion into electrical energy. This enables the measuring barrel to stabilize as soon as possible, avoids the measurement influence caused by vibration, and improves measurement efficiency and accuracy. The current is transmitted to the energy storage device for storage. The energy storage device can provide power to the electromagnetic discharge valve to realize the opening and closing of the electromagnetic discharge valve, achieving two goals at once.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments analyzed and obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] The purpose of this invention is to provide a mixed slurry concentration detection device to solve the problems existing in the prior art. By suspending the measuring tank, the weight data after the mixed slurry is filled can be obtained by a weighing sensor when detecting the concentration of the mixed slurry. Combined with the density of the mixed slurry and the volume of the measuring tank, the concentration value of the slurry can be calculated. The entire measurement process is rapid and is not affected by changes in slurry particle size, pipeline pressure, slurry bubbles, or material color. It also does not cause environmental pollution and has the advantages of high accuracy, good stability, and wide measurement range. At the same time, the vibration buffer uses a combination of three energy consumption methods: spring mechanical energy consumption, compressed gas energy consumption, and vibration energy converted into electrical energy. This allows the measuring tank to stabilize quickly, avoids the measurement influence caused by vibration, and improves measurement efficiency and accuracy. The current is transmitted to the energy storage device for storage, which can provide power to the electromagnetic discharge valve to realize the opening and closing of the electromagnetic discharge valve, achieving two goals at once.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] like Figures 1 to 8As shown, this embodiment provides a mixed slurry concentration detection device, including a measuring box. The measuring box contains a hoisting mechanism, a feeding mechanism, a measuring cylinder 3, and a power generation device. The hoisting mechanism includes a hoisting frame, a weighing sensor 12, and a vibration damper 13. The hoisting frame is installed on the inner wall of the measuring box, and the weighing sensor 12 is installed on the hoisting frame. The vibration damper 13 includes a cylinder 22, which is vertically arranged. The top of the cylinder 22 is connected to the bearing end of the weighing sensor 12. Inside the cylinder 22, there is a piston 23 and a spring 25. The piston 23 divides the inside of the cylinder 22 into a first chamber and a second chamber arranged vertically. The first chamber has an air hole 26. One end of the spring 25 is connected to the top of the first chamber, and the other end of the spring 25 is connected to the piston 23. The bottom end of the cylinder 22 has an air port 27, which is connected to the second chamber. The piston 23 has a pull rod 24 extending out of the air port 27. The measuring cylinder 3 is suspended by the pull rod 24 via the suspension rope 14. The top of the measuring cylinder 3 has an inlet, which is fed by a feeding mechanism for both material and water. The bottom of the measuring cylinder 3 has an outlet, which is equipped with an electromagnetic discharge valve. The power generation device includes a storage device, a rectifier, a permanent magnet 28, and a spiral coil 29. The permanent magnet 28 is housed inside the piston 23. The spiral coil 29 is located within the inner wall of the cylinder 22. The spiral coil 29 is electrically connected to the storage device via the rectifier to form a closed circuit. The storage device is electrically connected to the electromagnetic discharge valve. The spiral coil 29 is positioned along the movement path of the piston 23.
[0025] Working principle: ① Principle of mixed slurry concentration measurement: The slurry to be tested is fed into the measuring cylinder 3 through the feeding mechanism until the cylinder is full. After the measuring cylinder 3 stabilizes, the weighing sensor 12 obtains the weight data of the slurry. The weight data is then substituted into the calculation formula to obtain the concentration n of the slurry. The calculation formula is as follows:
[0026] Where V is the volume of the measuring cylinder 3, R is the particle density of the slurry to be tested, and G is the weight data obtained by the weighing sensor 12.
[0027] After the measurement is completed, the electromagnetic discharge valve opens to discharge the slurry inside the measuring cylinder 3. Then, clean water is injected into the measuring cylinder 3 through the feeding structure to clean the inside of the measuring cylinder 3. After cleaning, once the clean water in the measuring cylinder 3 is drained, the electromagnetic discharge valve closes, completing one concentration measurement of the mixed slurry. The entire measurement process is rapid and can set multiple sets of mixed slurry for continuous concentration detection. By comparing the concentration data obtained from multiple sets, the accuracy of concentration detection of mixed slurry is significantly improved.
[0028] ② Power generation and buffering principle: During the process of feeding slurry into the measuring cylinder 3, the measuring cylinder 3 will vibrate. The vibration will be transmitted to the pull rod 24 of the vibration damper 13 through the suspension rope 14. Under the action of the piston 23 and the spring 25, the vibration damper 13 converts the vibration of the measuring cylinder 3 into the up and down movement of the piston 23 in the cylinder 22. During the up and down movement of the piston 23, the spring 25 will continuously stretch and contract, consuming the vibration and absorbing the vibration energy. At the same time, the piston 23 will continuously compress and release the gas in the first chamber and the second chamber. The first chamber draws in and discharges gas through the air hole 26, and the gas in the second chamber draws in and discharges gas through the air port 27. During the infeed and discharge processes, work is done to consume vibration. As the piston 23 moves up and down repeatedly, it drives the permanent magnet 28 inside the spiral coil 29 to move up and down. The spiral coil 29 cuts the magnetic field generated by the permanent magnet 28, thereby generating current and converting vibration energy into electrical energy. This consumes vibration energy. Together with the spring 25 (mechanical energy consumption) and the air hole 26 (gas compression energy consumption), they work together to achieve energy dissipation, so that the measuring cylinder 3 can be stabilized as soon as possible, avoiding the measurement effects caused by vibration, improving measurement efficiency and accuracy. The current is sent to the energy storage device for storage, and the energy storage device can provide power to the electromagnetic discharge valve to realize opening and closing.
[0029] In one embodiment, the energy storage device is a battery.
[0030] In one embodiment, a feed funnel 15 is installed at the feed inlet of the measuring cylinder 3. The neck of the feed funnel 15 is provided with an overflow hole. A collection pipe 8 is provided on the inner wall of the measuring box. The inlet end of the collection pipe 8 is connected to the overflow hole through the overflow pipe 6, and the outlet end of the collection pipe 8 extends out of the measuring box. When the feeding mechanism delivers slurry into the measuring cylinder 3 through the feed funnel 15, after the slurry is filled to the overflow hole, the subsequently delivered slurry will flow into the overflow pipe 6 through the overflow hole and then be discharged along the collection pipe 8. When slurry is found to be discharged from the collection pipe 8, the feeding mechanism can be stopped.
[0031] In one embodiment, the slurry discharged from the collection pipe 8 can be recycled through a recycling container.
[0032] In one embodiment, the overflow pipe 6 is inclined, with its higher end connected to the feed funnel 15 and its lower end connected to the collection pipe 8. Preferably, the angle between the overflow pipe 6 and the feed funnel 15 is 120°.
[0033] In one embodiment, the measuring box is equipped with a wireless power supply module 9, and the energy storage device is electrically connected to the electromagnetic discharge valve through the wireless power supply module 9. This reduces the number of wires below the weighing point of the load cell 12, avoiding the influence of solid lines on the weight, thereby achieving high-precision measurement of the concentration of the mixed slurry.
[0034] In one embodiment, the feeding mechanism includes a feeding frame 5, which is fixedly connected to the inner wall of the measuring box via a fixing plate 34. The feeding frame 5 is located above the measuring cylinder 3. The bottom of the feeding frame 5 is provided with a water guide plate 30 and a guide head 31. The water guide plate 30 has water outlet holes, preferably arranged circumferentially on the water guide plate 30, which can spray clean water like a shower head to clean the measuring cylinder 3. A clean water pipe 32 and a feed pipe 33 are installed on the feeding frame 5, both extending out of the measuring box to supply external water and slurry to the equipment. The clean water pipe 32 is connected to the water guide plate 30 to provide clean water. The feed pipe 33 is connected to the guide head 31 to provide slurry to the guide head 31, which then supplies slurry to the feed funnel 15.
[0035] In one embodiment, an electromagnetic water valve is installed inside the water pipe 32, and an electromagnetic feed valve is installed inside the feed pipe 33. Both the electromagnetic water valve and the electromagnetic feed valve are electrically connected to the energy storage device via a wireless power supply module 9. The energy storage device and the wireless power supply module 9 provide power to the electromagnetic water valve and the electromagnetic feed valve, enabling them to open and close.
[0036] In one embodiment, the measuring box includes inflatable airbags 35, which are arranged on both sides of the measuring cylinder 3. The measuring box is provided with an inflation port 36, which is connected to the inflatable airbags 35. After connecting the inflation port 36 to the inflation device, the inflatable airbags 35 are inflated, and the inflatable airbags 35 on both sides of the measuring cylinder 3 can clamp the measuring cylinder 3, quickly stabilizing vibration. The inflatable airbags 35 are usually used in two situations. One is when the power supply in the energy storage device is sufficient and there is no need to rely on the relative movement of the permanent magnet 28 and the spiral coil 29 to generate electricity. In this case, the inflatable airbags 35 can be inflated to clamp the measuring cylinder 3 and work with the vibration damper 13 to achieve vibration stabilization. In this case, the inflatable airbags 35 play the main role in vibration stabilization. The other is to inflate the inflatable airbags 35 before the slurry is almost finished (such as when more than half of it has been poured) or when the pouring is finished, so as to achieve rapid vibration stabilization of the measuring cylinder 3.
[0037] In one embodiment, the hoisting frame includes a mounting frame 10 and a connecting frame 11. The mounting frame 10 is mounted on the inner wall of the measuring box. The bottom of the mounting frame 10 has a sliding groove, and the top of the mounting frame 10 has an exposed opening and a connecting bolt 18. A movable insert 16 is slidably disposed within the sliding groove. One end of the movable insert 16 has a lever protrusion extending from the exposed opening, and the other end of the movable insert 16 has a bolt through hole 17. The connecting bolt 18 can correspond to the bolt through hole 17 as it moves with the movable insert 16, i.e., the connecting bolt 18 can correspond to the bolt through hole 17. The top of the connecting frame 11 is provided with a connecting block 19. The side wall of the connecting block 19 has an insertion groove 20 for the end of the movable insert 16 with the bolt through hole 17 to be inserted. The top of the connecting block 19 has a threaded through hole 21, which communicates with the insertion groove 20 and is used for threaded connection with the connecting bolt 18.
[0038] Align the insertion slot 20 of the connecting bracket 11 with the movable insertion block 16 of the mounting bracket 10. Move the actuating protrusion to insert the movable insertion block 16 into the bottom of the insertion slot 20 of the connecting block 19. The threaded through hole 21 on the connecting block 19 will then align with the bolt through hole 17 of the movable insertion block 16. Tighten the connecting bolt 18 to make it threaded into the threaded through hole 21. Continue to tighten the connecting bolt 18 until it passes through the bolt through hole 17, thus connecting the connecting bracket 11 and the mounting bracket 10. Unscrew the connecting bolt 18 out of the threaded through hole 21 on the connecting block 19 and disengage the movable insertion block 16 from the insertion slot 20 of the connecting block 19, thus disassembling the connecting bracket 11 and the mounting bracket 10. The connecting bracket 11 and the mounting bracket 10 can be disassembled, allowing the load cell 12 to be removed with the connecting bracket 11 for repair and maintenance.
[0039] In one embodiment, the mounting bracket 10 is connected to the side wall of the measuring box by a bolt group, and the surface of the weighing sensor 12 is connected to the connecting bracket 11 by a plurality of limiting bolts.
[0040] In one embodiment, the measuring chamber is further provided with a receiving hopper 4, located below the discharge port of the measuring cylinder 3. A discharge pipe 7 is provided on the side wall of the receiving hopper 4, extending out of the measuring chamber to discharge slurry. When the electromagnetic discharge valve is opened, the slurry or water in the measuring cylinder 3 falls into the receiving hopper 4 and is then discharged through the discharge pipe 7. The slurry discharged from the receiving hopper 4 can be recycled using a recovery container.
[0041] In one embodiment, the measuring box includes a box body 1 and a box cover 2. The opening of the box body 1 is located at the top, and the box cover 2 is detachably installed at the opening. By opening the box cover 2, various mechanisms inside the box body 1 can be repaired.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
