Description

Technical Field

[0001] This invention relates to the field of manganese pollution control technology, specifically to a manganese pollution control device for iron mines and its usage method. Background Technology

[0002] The mining, beneficiation, and smelting processes in iron ore mines generate large amounts of manganese-contaminated wastewater. Direct discharge of this wastewater can lead to the accumulation of manganese in surrounding water bodies and soil, disrupting the ecological balance and potentially entering the human body through the food chain, harming the nervous system, liver, and other organs. Therefore, the efficient treatment of manganese-contaminated wastewater from iron ore mines is a crucial issue in the field of mining environmental protection, and the research and optimization of related treatment equipment is urgently needed.

[0003] Currently, the treatment of manganese-contaminated water from iron ore mines mostly adopts a step-by-step treatment model involving reagent addition, mixing reaction, filtration separation, and waste residue cleaning. Each step typically relies on independent equipment or manual operation. For example, reagent addition requires manual control of dosage and frequency, which can easily lead to incomplete reactions due to untimely or excessive addition; the mixing reaction relies on a separate stirring device, lacking coordination with the filtration stage, and may affect pollutant removal efficiency due to uneven mixing; cleaning the filter residue after filtration often requires manual scraping after machine shutdown, which not only interrupts the treatment process but may also cause filter plate blockage and reduce filtration efficiency due to untimely cleaning. In addition, manual intervention in each step is prone to asynchronous operation, which not only increases labor costs but also causes fluctuations in treatment results due to human error, making it difficult to achieve continuous, stable, and efficient treatment. Therefore, there is an urgent need for an integrated treatment device that can achieve full-process coordinated operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an iron ore manganese pollution treatment equipment and its usage method, which solves the problem that the treatment of manganese-polluted water in iron ore mines often adopts a step-by-step treatment mode of reagent addition, mixing reaction, filtration separation and waste residue cleaning.

[0007] Preferably, the rebound assembly includes two fixed plates 1 fixedly connected to the front end of the connecting frame. Each of the two fixed plates 1 has a sliding rod fixedly connected to one end of its proximity. The outer wall of the sliding rod is slidably connected to the inner wall of the fixed plate 2. A spring 1 is provided on the outer wall of the sliding rod. One end of the spring 1 is connected to the fixed plate 2, and the other end of the spring 1 is connected to the right fixed plate 1.

[0008] Preferably, the storage assembly includes a discharge pipe fixedly connected to the top of the connecting frame, a storage tank fixedly connected to the top of the discharge pipe, the bottom of the storage tank fixedly connected to the top of the filter cylinder, and a top cover rotatably connected to the top of the storage tank.

[0009] Preferably, the actuating mechanism includes a full-tooth gear fixedly connected to the outer wall of the rotating rod, a toothed ring meshing with the left end of the full-tooth gear, a support rod fixedly connected to the bottom end of the toothed ring, the bottom end of the support rod slidably connected to the top end of the guide plate, and a mud-pulling plate connected to the outer wall of the support rod through an elastic component.

[0010] Preferably, the elastic component includes a support ring 1 fixedly connected to the outer wall of the support rod, a support ring 2 connected to the bottom end of the support ring 1 via a spring 2, one end of the spring 2 connected to the support ring 1, the other end of the spring 2 connected to the support ring 2, the inner wall of the support ring 2 slidably connected to the outer wall of the support rod, and the bottom end of the support ring 2 fixedly connected to the top of the mud-removing plate.

[0011] Preferably, a water inlet pipe is fixedly connected to the top left side of the filter cylinder, a water outlet pipe is fixedly connected to the bottom front side of the filter cylinder, and a mud outlet pipe is fixedly connected to the right side of the bottom of the mud storage tank.

[0012] Preferably, a motor is mounted on the top of the filter cartridge via a fixing frame, the motor drive end is fixedly connected to the top of the rotating rod, and the guide plate is an annular ring with the left side higher than the right side.

[0013] A method for using a manganese pollution control device in an iron ore mine includes the following steps: Step 1: Inject the manganese-contaminated water into the filter cartridge through the inlet pipe. The water flows through the through holes of the water storage container and is evenly dispersed. Start the motor and drive the rotating rod to rotate the stirring blade and the arc scraper counterclockwise. Step 2: Rotating rod 1 drives rotating rod 2 and rotating rod 3 synchronously via a synchronous belt. The toothed gear of rotating rod 2 intermittently meshes with the toothed plate, pushing the baffle to slide and compressing spring 1, so that the agent in the storage tank is quantitatively added to the filter cylinder through discharge pipe 1 and discharge pipe 2. The stirring blades force the mixing of the agent and the polluted water. Step 3: The mixture is filtered through three layers of filter plates in stages. Manganese pollutants are trapped and form filter residue. The arc-shaped scraper scrapes the filter residue to the mud outlet and falls into the mud storage tank as the rotating rod rotates. Step 4: Rotating rod 3 drives the full-tooth gear to mesh with the gear ring, causing the support rod to move along the circumference of the inclined guide plate. Under the action of spring 2, the mud-dispensing plate undulates tightly against the guide plate, pushing the filter residue to be discharged through the mud outlet pipe. Step 5: Regularly open the top cover to replenish the medicine in the storage tank.

[0014] Preferably, in step two, the toothed gear can trigger a tooth plate displacement once each time it rotates to the same position, ensuring the frequency of drug dosing.

[0015] Working principle: First, manganese-contaminated water is introduced into the filter cartridge through the inlet pipe. The water flow first enters the water storage container on the top side of the inner wall of the filter cartridge. With the help of the evenly distributed through holes at the bottom of the water tank, the originally concentrated water flow is dispersed into multiple fine streams, avoiding direct impact on the filter plates and causing local overload, thus providing a stable water flow foundation for subsequent treatment. At this time, the motor mounted on the top of the filter cartridge via a fixed frame is started. The motor drive drives the rotating rod to rotate counterclockwise on the inner wall of the filter cartridge. The stirring blades and three arc-shaped scrapers on the outer wall of the rotating rod rotate synchronously. The stirring blades are located below the water storage container to prepare for the subsequent mixing of the reagents and the contaminated water. The arc-shaped scrapers correspond to the three filter plates in the middle of the inner wall of the filter cartridge, respectively, and the filter cartridge enters the working state. As rotating rod one rotates, the synchronous belt on the top side of its outer wall synchronously drives rotating rod two and rotating rod three to rotate. When rotating rod two rotates, the toothed gear fixed on its outer wall rotates accordingly. When the toothed part of the toothed gear rotates to mesh with the toothed plate, it will push the toothed plate and the baffle fixed at the front end of the toothed plate to slide on the inner wall of the connecting frame. During the sliding process of the baffle, it will drive the fixed plate two at the front end to move along the slide rod between the two fixed plates one, and compress the spring one on the outer wall of the slide rod. At this time, the baffle disengages from the connection between the discharge pipe one and the discharge pipe two in the connecting frame, and the agent in the storage tank flows into the filter cylinder in a metered manner through the discharge pipe one and the discharge pipe two. Moreover, the toothed gear will trigger the toothed plate to move once every time it rotates to the same position, ensuring the stability of the agent addition frequency. When the toothless part of the toothed gear rotates to the toothed plate, the spring one rebounds and drives the baffle to reset, blocking the agent addition channel again, realizing the timed and metered addition of the agent. The reagents added to the filter cartridge are fully mixed with the polluted water that has been dispersed in the water storage container under the forced rotation of the stirring blades, which accelerates the reaction between manganese pollutants and reagents. The mixed liquid then flows to three vertically arranged filter plates with progressively smaller pore sizes. Through the three layers of filter plates, manganese pollutants are effectively trapped and form filter cake, while the purified water is discharged through the outlet pipe at the bottom front of the filter cylinder. During this process, the arc-shaped scraper, which rotates with the rotating rod, remains in contact with the top of the filter plates, continuously scraping the filter cake trapped on the surface of the filter plates towards the mud outlet in the middle of the outer wall of the filter cylinder. The filter cake falls through the mud outlet into the mud storage tank fixed on the outer wall of the filter cylinder, preventing the filter cake from clogging the filter plates and affecting the filtration efficiency. Meanwhile, the rotating rod three rotates under the drive of the synchronous belt, and the full-tooth gear on its outer wall meshes with the gear ring, driving the support rod at the bottom of the gear ring to make a circular motion along the guide plate on the inner wall of the sludge storage tank. Since the guide plate is an annular ring with the left side higher than the right side, the support rod moves along the inclined direction of the guide plate while making a circular motion; while the support ring one on the outer wall of the support rod is connected to the support ring two through the spring two, the mud-pushing plate at the bottom of the support ring two is always in close contact with the surface of the guide plate under the elastic force of the spring two, and rises and falls with the inclination angle of the guide plate, thereby continuously pushing the filter residue in the sludge storage tank to the mud discharge pipe on the right side of the bottom of the sludge storage tank, realizing the centralized discharge of the filter residue.

[0016] This invention provides equipment for treating manganese pollution in iron ore mines and its method of use. It has the following beneficial effects: 1. This invention uses an electric motor as the core power source, and drives rotating rods two and three synchronously via rotating rod one and a synchronous belt to achieve full-process mechanical linkage of reagent addition, stirring and mixing, filter residue scraping and automatic slag discharge. Each step can be precisely coordinated without human intervention, avoiding the efficiency loss caused by asynchronous manual operation in traditional step-by-step treatment, greatly improving the overall treatment efficiency, and reducing the impact of human operation error on the treatment effect, ensuring stable effluent water quality.

[0017] 2. This invention achieves timed and quantitative addition of chemicals through the cooperation of a toothed gear and spring one, avoiding excessive waste of chemicals and reducing chemical consumption. In addition, the arc-shaped scraper can clean the filter plate surface of the filter plate in real time. Combined with the adaptive movement of the mud-removing plate closely attached to the inclined guide plate under the action of spring two, it can effectively prevent filter plate blockage and sludge accumulation in the mud storage tank, reduce the frequency of equipment cleaning and energy consumption, thereby reducing the overall operating cost.

[0018] 3. The through holes of the water storage container of this invention enable uniform water flow dispersion, and the three-layer filter plates intercept manganese pollutants in stages. Combined with the mixing of the agent and polluted water by the stirring blades, the removal effect of manganese pollutants is significantly improved, ensuring that the water quality meets the standards after treatment. At the same time, the filter residue is discharged centrally through the sludge outlet and sludge pipe to avoid secondary pollution, thus achieving a deep treatment that integrates purification and sludge discharge.
