Description

Technical Field

[0001] This utility model relates to the field of manganese slag treatment technology, specifically a manganese slag washing device. Background Technology

[0002] Manganese slag is a solid waste generated during the smelting and processing of manganese ore. It mainly originates from the production process of manganese-based products (such as metallic manganese, electrolytic manganese, ferromanganese alloy, manganese dioxide, etc.) and is one of the industrial wastes with large emissions in the manganese industry. The generation of manganese slag directly depends on the processing technology of manganese ore.

[0003] For example, Chinese utility model patent with publication number "CN220591076U" discloses a low-cost electrolytic manganese slag washing device; In this low-cost electrolytic manganese slag washing device, the operator pours manganese slag and water into the feed hopper in a certain proportion, which facilitates the entry of the feed hopper into the crushing and mixing component. The processing box has a certain inclination angle to ensure that the water will not be drained immediately. The water and manganese slag are fully crushed and mixed in the crushing and mixing component, and then the manganese slag is transported by the stirring and conveying component.

[0004] The aforementioned prior art has the following shortcomings in practical implementation: although the water in this application is not immediately discharged, the application cannot reuse the water source, resulting in a relatively high consumption of water resources. Summary of the Invention

[0005] One of the technical problems that this application aims to solve is that although existing manganese slag washing devices can crush and mix manganese slag, they cannot recycle and reuse the water used for washing, resulting in a large amount of water consumption during the washing process, which increases the cost of industrial water use and does not meet the environmental protection requirements of resource conservation.

[0006] To address the aforementioned technical problems, this application provides a manganese slag washing device, comprising: A mixing tank, the top of which is open; A circulation structure is provided on the lower side of the mixing tank. The circulation structure includes a first connecting column, which is fixedly connected to the lower side of the mixing tank; a filter frame, which is fixedly connected to the lower side of the first connecting column; a filter screen, which is fixedly connected inside the filter frame; a second connecting column, which is fixedly connected to the lower side of the filter frame; a collection tank, which is fixedly connected to the lower side of the second connecting column; a water pump, which is fixedly installed at the bottom of the collection tank; and a circulation pipe, one end of which is fixedly connected to the output end of the water pump, and the other end of which is fixedly connected to the surface of the mixing tank and communicates with the mixing tank.

[0007] In some embodiments, the stirring tank, filter frame, and collection tank are all cylindrical, and there are multiple first connecting columns and second connecting columns.

[0008] In some embodiments, the mixing tank is provided with a mixing and crushing structure, which includes: a motor, the motor being fixedly installed on the lower side of the mixing tank; a rotating shaft, the rotating shaft being fixedly installed on the output end of the motor; a mixing rod, a plurality of the mixing rods being fixedly connected to the side surface of the rotating shaft, a plurality of the crushing blades being fixedly connected to the side surface of the rotating shaft, and a protective frame being fixedly connected to the outside of the motor on the lower side of the mixing tank.

[0009] In some embodiments, the stirring rod is fixedly connected to a lower position on the rotating shaft, and the pulverizing blade is fixedly connected to an upper position on the rotating shaft.

[0010] In some embodiments, a flow structure is provided on the lower side of the mixing tank, the flow structure including a flow pipe fixed around the lower side of the mixing tank and communicating with the mixing tank, and a valve installed inside the flow pipe.

[0011] In some embodiments, the mixing tank is provided with a feeding structure, which includes a retaining ring slidably connected to the inner wall of the mixing tank, a cover plate fixedly connected to the upper side of the retaining ring, a frustum-shaped feeding port penetrating inside the cover plate, and handles fixedly connected to both sides of the cover plate.

[0012] In some embodiments, the front surface of the filter frame is provided with a discharge port, and the lower side of the collection bucket is fixedly connected to a base.

[0013] This utility model has at least the following beneficial effects: Through a circulation structure consisting of a mixing tank, a filter frame, a collection tank, a water pump, and a circulation pipe, the mixed liquid after washing manganese slag can achieve solid-liquid separation by passing through the filter plate screen in the filter frame. After the liquid is temporarily stored in the collection tank, it is pumped back to the mixing tank by the water pump through the circulation pipe for reuse in washing. This significantly reduces the amount of fresh water used and greatly improves the water resource utilization rate, thereby reducing industrial water costs and environmental treatment pressure.

[0016] 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 obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a manganese slag washing device, comprising: Mixing tank 1, with an open top; A circulation structure is provided on the lower side of the mixing tank 1. The circulation structure includes a first connecting column 101, which is fixedly connected to the lower side of the mixing tank 1; a filter frame 102, which is fixedly connected to the lower side of the first connecting column 101; a filter screen 103, which is fixedly connected inside the filter frame 102; a second connecting column 104, which is fixedly connected to the lower side of the filter frame 102; a collection tank 105, which is fixedly connected to the lower side of the second connecting column 104; a water pump 106, which is fixedly installed at the bottom of the collection tank 105; and a circulation pipe 107, one end of which is fixedly connected to the output end of the water pump 106, and the other end of which is fixedly connected to the surface of the mixing tank 1 and communicates with the mixing tank 1. The mixing tank 1, the filter frame 102, and the collection tank 105 are all cylindrical, and there are several first connecting columns 101 and second connecting columns 104.

[0018] Through the above technical solution, the first connecting column 101 and the second connecting column 104 respectively realize the fixed connection between the stirring tank 1 and the filter frame 102, and the filter frame 102 and the collection tank 105. The distribution design of several connecting columns can ensure the stability of the connection between the three, while reserving reasonable space for the flow of the mixed liquid. The filter plate 103 inside the filter frame 102 can accurately intercept solid manganese slag particles in the mixed liquid, allowing only the liquid containing soluble substances (such as sulfates and heavy metal ions) dissolved in the manganese slag to pass through, thus achieving "solid-liquid separation". The collection tank 105 temporarily stores the filtered liquid, and the water pump 106 at the bottom provides power to transport the liquid back to the stirring tank 1 through the circulation pipe 107 for reuse in manganese slag washing, which greatly reduces the amount of fresh water to be added and improves the water resource utilization rate. The cylindrical design of the stirring tank 1, the filter frame 102 and the collection tank 105 is more conducive to the uniform flow of the mixed liquid than other shapes, reduces the liquid residue in the device, and facilitates processing, manufacturing and subsequent cleaning and maintenance.

[0019] Please see Figures 1-5 The mixing tank 1 is equipped with a mixing and crushing structure, which includes: a motor 201, which is fixedly installed on the lower side of the mixing tank 1; a rotating shaft 202, which is fixedly installed on the output end of the motor 201; a mixing rod 203, several mixing rods 203 are fixedly connected to the side surface of the rotating shaft 202, and several crushing blades 204 are fixedly connected to the side surface of the rotating shaft 202; a protective frame 205 is fixedly connected to the outside of the motor 201 on the lower side of the mixing tank 1; the mixing rods 203 are fixedly connected to the lower position on the rotating shaft 202, and the crushing blades 204 are fixedly connected to the upper position on the rotating shaft 202.

[0020] Through the above technical solution, the motor 201 serves as the power source, driving the rotating shaft 202 to rotate stably, providing power for subsequent crushing and mixing; the external protective frame 205 can prevent the motor from being hit by external collisions during operation, and at the same time prevent operators from accidentally touching the rotating parts, improving the safety of the device; the crushing blades 204 on the upper side of the rotating shaft 202 crush the large pieces of manganese slag that have just been put in into the machine into fine particles through high-speed rotation—the smaller the manganese slag particles, the larger the contact area with water, and the higher the dissolution efficiency of soluble substances during subsequent washing, avoiding the presence of unwashed soluble components inside the large pieces of manganese slag; the stirring rod 203 on the lower side of the rotating shaft 202 fully stirs the crushed manganese slag and water to form a uniform mixture, further promoting the dissolution of soluble substances, while preventing manganese slag particles from settling at the bottom of the mixing tank 1, ensuring that every piece of manganese slag can come into contact with the washing water; the layered layout of "crushing blades on top and stirring rods on the bottom" allows the crushing and mixing processes to be carried out simultaneously without interference, eliminating the need for an additional separate crushing device, simplifying the device structure, and reducing equipment costs and floor space.

[0021] Please see Figures 1-5The mixing tank 1 has a flow structure on its lower side, which includes a flow pipe 301 fixed around the lower side of the mixing tank 1 and communicating with the mixing tank 1, and a valve 302 installed inside the flow pipe 301.

[0022] Through the above technical solution, the flow pipes 301 around the lower side of the mixing tank 1 can evenly guide the mixed liquid in the mixing tank 1 to the filter frame 102, avoiding the mixed liquid from concentrating and impacting a certain area of ​​the filter plate mesh 103 due to a single flow port, causing local blockage or reduced filtration efficiency; the valves 302 inside the flow pipes 301 can flexibly control the flow and shut-off of the mixed liquid: the valves 302 are closed during the mixing and washing stage, so that a closed space is formed inside the mixing tank 1, ensuring that the manganese slag and water have sufficient time to mix and dissolve soluble substances; after washing, the valves 302 are opened, and the mixed liquid enters the filtration stage again, ensuring that each step of the process is carried out in an orderly manner, and avoiding the premature entry of the unwashed mixed liquid into the filtration structure.

[0023] Please see Figures 1-5 The mixing tank 1 is provided with a feeding structure, which includes a retaining ring 401 slidably connected to the inner wall of the mixing tank 1, a cover plate 402 fixedly connected to the upper side of the retaining ring 401, a frustum-shaped feeding port 403 that passes through the inside of the cover plate 402, and handles 404 fixedly connected to both sides of the cover plate 402.

[0024] Through the above technical solution, the cover plate 402 is slidably connected to the inner wall of the mixing tank 1 via the retaining ring 401, which not only facilitates the operator to disassemble the cover plate as needed (such as for maintenance and cleaning of the inside of the mixing tank 1), but also ensures the sealing between the cover plate and the mixing tank 1, preventing the mixture from splashing during the mixing process; the frustum-shaped discharge port 403 (wider at the top and narrower at the bottom) on the cover plate 402 is more conducive to the smooth input of manganese slag (especially granular manganese slag) compared to the ordinary circular discharge port, reducing the blockage of manganese slag at the discharge port; at the same time, the frustum shape can reduce the risk of the mixture overflowing from the discharge port during the mixing process after the material is fed; the handles 404 on both sides of the cover plate 402 provide the operator with a force point for disassembling and installing the cover plate, making it easy to remove or install the cover plate and improving the convenience of operation.

[0025] Please see Figures 1-5 The front surface of the filter frame 102 is provided with a discharge port 501, and the lower side of the collection bucket 105 is fixedly connected to the base 502.

[0026] Through the above technical solution, the discharge port 501 on the front side of the filter frame 102 provides a discharge channel for the filtered solid manganese slag. When the amount of manganese slag trapped in the filter frame 102 reaches a certain amount, the operator can quickly clean the residue through the discharge port 501 without disassembling the filter frame 102, simplifying the cleaning process and reducing the downtime of the device. The base 502 on the lower side of the collection tank 105 increases the contact area between the device and the ground, lowers the center of gravity of the device, and prevents the device from tipping over due to the weight of the top mixing tank 1, motor and other components. At the same time, it keeps the water pump 106 at the bottom of the collection tank 105 at a certain distance from the ground, preventing water from the ground from soaking the water pump and extending the service life of the water pump.

[0027] All electrical devices in this invention are powered by an external power source; Working principle and usage procedure: During use, manganese slag and an appropriate amount of water are added into the mixing tank 1 through the frustum-shaped discharge port 403 on the cover plate 402. The valve 302 is closed to form a closed mixing space inside the mixing tank 1. The motor 201 is started, and its output end drives the rotating shaft 202 to rotate. The crushing blades 204 located on the upper side of the rotating shaft 202 crush the added manganese slag, breaking down large pieces of manganese slag into fine particles, enhancing the subsequent washing effect. At the same time, the stirring rod 203 on the lower side of the rotating shaft 202 thoroughly stirs and mixes the manganese slag and water, allowing soluble substances in the manganese slag (such as sulfates, heavy metal ions, etc.) to dissolve into the water. After the stirring and washing are completed, the valve 302 in the flow pipe 301 is opened, and the mixed liquid flows into the filter frame 102 below through the flow pipe. The filter screen 103 in the filter frame 102 filters the mixed liquid, intercepting solid manganese slag particles, while the liquid passes through the filter screen and enters the collection tank 105 below. At this point, the water pump 106 at the bottom of the collection tank 105 is activated. The pump re-pumps the collected filtrate into the mixing tank 1 through the circulation pipe 107, realizing the recycling of water resources and reducing water consumption. When it is necessary to clean the filtered manganese slag, the retained solid residue can be discharged through the discharge port 501 on the front side of the filter frame 102. The entire process achieves efficient washing treatment of manganese slag through the synergistic effect of stirring and crushing, filtration and separation, and water circulation, while reducing water consumption through the water circulation structure.
