[0002] Magnetic coagulation water treatment is an advanced water treatment method that combines traditional coagulation technology with magnetic separation technology. By introducing magnetic particles, it enhances the efficiency of solid-liquid separation and achieves rapid water purification. In the magnetic coagulation water treatment process, the amount of magnetic powder added is crucial to the treatment effect and cost control.

[0003] Traditional magnetic powder dosing methods suffer from the following problems: 1. Manual dosing is labor-intensive, inaccurate, and involves impact dosing, making stable dosing difficult, resulting in magnetic powder waste or poor processing effects; 2. Insufficient automation: While some existing dosing devices have simple timing and metering functions, manual transport of the magnetic powder to the storage tank and then manual pouring into the silo is still required; 3. Dust pollution and safety hazards: During open storage and conveying processes, magnetic powder dust is prone to leakage, polluting the working environment and potentially harming human health, failing to meet the demands of efficient and stable magnetic powder dosing in actual production. Therefore, there is an urgent need for an automatic magnetic powder dosing device that can accurately measure, is highly automated, and operates stably. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3An automatic magnetic powder dosing device for a magnetic coagulation process includes a magnetic powder storage silo 1, a magnetic powder storage tank 2 located on the side of the magnetic powder storage silo 1, a feed hopper 5 located on the top surface of the magnetic powder storage silo 1 near the left side, a vacuum conveying pump 9 fixedly installed at the upper end of the magnetic powder storage tank 2, the input end of the vacuum conveying pump 9 being connected to the magnetic powder storage tank 2, and the output end of the vacuum conveying pump 9 being connected to a vacuum conveying pipe 10, which is connected to the feed hopper 5. The magnetic powder in the magnetic powder storage tank 2 is conveyed to the feed hopper 5 by the vacuum conveying pump 9 and the vacuum conveying pipe 10, and then introduced into the magnetic powder storage silo 1 along the feed hopper 5. The device comprises the magnetic powder storage silo 1, the magnetic powder storage tank 2, the feed hopper 5, the discharge hopper 6, and a horizontal conveyor. Both the trough 7 and the scraper conveyor body 8 are fully sealed. The magnetic powder storage bin 1 and the discharge hopper 6 are fixed together by a flexible connector 11. The magnetic powder storage bin 1 is fixedly installed on the arc-shaped side wall above the flexible connector 11 with a vibration motor 12 and a pulse air disc 13. The vibration motor 12 and the pulse air disc 13 keep the magnetic powder in the magnetic powder storage bin 1 in a loose state, ensuring that the magnetic powder clumps inside the magnetic powder storage bin 1 and falls evenly. A level gauge 14 is fixedly installed on the upper right side of the magnetic powder storage bin 1. The level gauge 14 is used to detect the amount of magnetic powder stored in the bin in real time and feed the signal back to the central control platform (not shown in the figure). When the amount of magnetic powder stored is lower than the set value, the control unit issues an alarm to prompt the replenishment of magnetic powder.

[0023] Several supports 3 are fixedly installed on the annular sidewall near the lower end of the magnetic powder storage silo 1. Support piles 4 are fixedly installed at the lower ends of each support 3, and weighing modules 15 are fixedly installed on each support pile 4. The weighing modules 15 are connected to a central control platform (not shown in the figure) and can monitor the weight of the magnetic powder in the storage silo in real time. The central control platform precisely controls the discharge rate of the metering unit based on the set dosage and the weight data fed back by the gravity sensor. The central control platform is fixedly installed on the magnetic powder storage silo 1. The scraper conveyor body 8, vacuum pump 9, vibration motor 12, pulse disc 13, level gauge 14, tilting mechanism, screw conveyor mechanism, and several weighing modules 15 are all associated with the central control platform.

[0024] A tilting mechanism is vertically installed through the top surface of the magnetic powder storage silo 1. The tilting mechanism includes a first motor 16 fixedly installed at the upper end of the center position of the magnetic powder storage silo 1. A rotating rod 17 is fixedly installed at the lower end of the drive shaft of the first motor 16. The lower end of the rotating rod 17 is vertically rotatably installed through the top surface of the center position of the magnetic powder storage silo 1. A spiral stirring rod 18 is fixedly installed at the lower end of the rotating rod 17. The spiral stirring rod 18 is located at the conical bottom of the magnetic powder storage silo 1. Several L-shaped stirring rods 19 are fixedly installed on the annular side wall of the rotating rod 17. The L-shaped stirring rods 19 are evenly distributed. The first motor 16 drives the rotating rod 17 and the spiral stirring rod 18 to rotate, so that the rotating rod 17 drives the several evenly distributed L-shaped stirring rods 19 to continuously tilt and stir the magnetic powder in the magnetic powder storage silo 1, preventing the magnetic powder from clumping and clogging.

[0025] A discharge hopper 6 is connected to the lower end of the magnetic powder storage silo 1. A horizontal conveying trough 7 is connected directly below the discharge hopper 6. A screw conveying mechanism is installed inside the horizontal conveying trough 7. The screw conveying mechanism includes a second motor 20 fixedly installed below the magnetic powder storage silo 1. A drive wheel 21 is fixedly installed at the drive end of the second motor 20. A screw conveying rod 22 is horizontally rotatably installed through the inner walls on both sides of the horizontal conveying trough 7. A driven wheel 23 is coaxially fixedly connected to one end of the screw conveying rod 22 outside the horizontal conveying trough 7. The drive wheel 21 and the driven wheel 23 are connected by a belt. The second motor 20 drives the belt-driven drive wheel 21 and driven wheel 23 to rotate, which in turn drives the spiral conveyor rod 22 in the horizontal conveying trough 7 to rotate. The spiral conveyor rod 22 then transports the magnetic powder from the magnetic powder storage bin 1 into the horizontal conveying trough 7 and into the scraper conveyor body 8. The scraper conveyor body 8 is connected to the bottom of the horizontal conveying trough 7 near the right side. The combination of quantitative spiral conveying and scraper conveyor body 8 allows for precise adjustment of the conveying volume. The scraper conveyor body 8 can transport the magnetic powder to the high-level addition point.

[0026] In use, this invention utilizes a vacuum pump 9 and a vacuum conveying pipe 10 to transport the magnetic powder from the magnetic powder storage tank 2 to the feed hopper 5, and then guides it into the magnetic powder storage silo 1 along the feed hopper 5. A level gauge 14 inside the magnetic powder storage silo 1 detects the amount of magnetic powder in the silo, and a weighing module 15 on several support piles 4 assists in precisely adjusting the amount of magnetic powder added. A vibration motor 12 and a pulse air disc 13 on the wall of the magnetic powder storage silo 1 keep the magnetic powder in the silo 1 loose, ensuring that the magnetic powder clumps inside the silo 1 and falls evenly. The first motor 16 at the top of the magnetic powder storage silo 1 is started, driving the rotating rod 17 and the spiral stirring rod 18 to rotate, thus... The rotating rod 17 drives several L-shaped stirring rods 19, which are evenly spaced, to continuously rotate and stir the magnetic powder in the magnetic powder storage bin 1, preventing the magnetic powder from clumping and clogging. The second motor 20 drives the driving wheel 21 and the driven wheel 23, which are connected by belt drive, to rotate. This causes the driven wheel 23 to drive the spiral conveying rod 22 in the horizontal conveying trough 7 to rotate. The spiral conveying rod 22 then transports the magnetic powder from the magnetic powder storage bin 1 into the horizontal conveying trough 7 to the scraper conveyor body 8, where it is fed. This effectively solves the problem of clumping and clogging of magnetic powder during storage and transportation, ensuring the continuous and stable operation of the device and reducing the frequency and cost of equipment maintenance.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
