Description

Technical Field

[0001] This utility model belongs to the field of adjustment structure technology, and in particular relates to a ternary vibrating screen grading adjustment structure for the production of electrolytic manganese ultrafine powder. Background Technology

[0002] Electrolytic manganese ultrafine powder is a high-purity metallic manganese powder prepared by electrolysis. The main component is metallic manganese, with a purity exceeding 91% and extremely low impurity content. Depending on the production process, some products may contain small amounts of manganese dioxide or manganese sulfate. Electrolytic manganese ultrafine powder is a silvery-gray powder that is easily oxidized and requires sealed storage. The ultrafine powder exhibits excellent dispersibility and reactivity, resulting in characteristics such as small particle size, large specific surface area, and high activity. Electrolytic manganese ultrafine powder is widely used in the metallurgical industry as a desulfurizing agent or alloying additive, in battery manufacturing as a cathode material for lithium manganese oxide batteries, and in chemical production as a raw material for the production of chemical products such as potassium permanganate.

[0003] In the production process of electrolytic manganese ultrafine powder, the ternary vibrating screen is a key piece of equipment for achieving fine material classification. Traditional ternary vibrating screens mostly use static and fixed screen installation. Under long-term high-intensity vibrating screening operations, the screen will undergo plastic elongation and fatigue relaxation, resulting in a decrease in tension. Screen relaxation leads to uneven stress on the screen and local stress concentration, which significantly shortens the service life of the screen. Secondly, abnormal shaking of the screen surface during vibration causes materials of different particle sizes to cross between each other, affecting screening accuracy. At the same time, untreated electrolytic manganese ultrafine powder raw materials are usually directly fed into the ternary vibrating screen for classification. These raw materials often contain some ultrafine powder that does not meet the current production standards. Some non-compliant materials directly enter the main screening system, increasing the load on the main screen, reducing the overall screening efficiency, and may also be mixed with qualified products, affecting product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the inability to dynamically adjust the tension of the traditional ternary vibrating screen and the impact of non-compliant materials mixed in the raw materials on product quality, and to propose a ternary vibrating screen grading and adjustment structure for the production of electrolytic manganese ultrafine powder.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a ternary vibrating screen grading and adjustment structure for producing electrolytic manganese ultrafine powder, comprising a shell, a top cover connected to the top of the shell, a feed inlet connected to the top of the top cover, a tensioning mechanism including a screen disposed inside the shell, multiple rotating rings arranged around the axis inside the shell, hooks connected to the outer wall of the rotating rings, the screen being configured to hook its edge onto the hooks, the tension of the screen being adjusted by rotating the rotating rings, and a pre-screening mechanism including a screen plate disposed inside the feed inlet, the screen plate being configured with a aperture smaller than the maximum standard particle size of electrolytic manganese ultrafine powder, thereby removing electrolytic manganese ultrafine powder that does not meet the minimum production standards.

[0006] Preferably, the housing has two fixing rings inside, and the outer wall of the fixing rings is provided with a plurality of rotating seats around the axis of the housing, and the outer wall of the rotating seats is slidably connected to the inner wall of the rotating rings.

[0007] Preferably, a toothed ring is slidably connected between the two fixed rings, and multiple contact rods are arranged around the top outer wall of the toothed ring along the toothed ring axis. Multiple spiral grooves are opened on the inner wall of the rotating ring, and the top outer wall of the contact rod contacts the inner wall of the spiral groove.

[0008] Preferably, one side of the fixed ring is rotatably connected to a gear via a block, and a first motor is installed on the outer wall of the bottom of the block, with the output end of the first motor connected to one side of the gear.

[0009] Preferably, a protective shell is connected to the top of the feed inlet, a rotating shaft is rotatably connected to the bottom of the protective shell, multiple blades are arranged around the outer wall of the rotating shaft along the axis, a second motor is connected to the inner wall of the protective shell, and the output end of the second motor is connected to the top of the rotating shaft.

[0010] Preferably, a receiving box is connected to the top of the top cover, a baffle is provided inside the receiving box, a discharge port is connected to one side of the outer wall of the outer shell, and a base is connected to the bottom of the outer shell.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting a tensioning mechanism, the tension of the screen can be dynamically adjusted according to the actual working conditions and production needs, so that the screen always maintains the optimal tension, ensuring that the screen is subjected to uniform force, extending the screen life, avoiding material leakage caused by loosening, and reducing maintenance difficulty and maintenance cost.

[0013] 2. In this utility model, by setting a pre-screening mechanism, electrolytic manganese ultrafine powder that does not meet the production standards is separated from electrolytic manganese ultrafine powder that meets the production standards before entering the equipment, and the electrolytic manganese ultrafine powder that does not meet the production standards is collected, thereby reducing the difficulty of screening, improving the screening efficiency, and improving product quality.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5This utility model provides a technical solution: a ternary vibrating screen grading and adjustment structure for producing electrolytic manganese ultrafine powder, including a shell 1, a top cover 6 connected to the top of the shell 1, a feed inlet 7 connected to the top of the top cover 6, a tensioning mechanism 5, a screen 4 disposed inside the shell 1, multiple rotating rings 503 arranged around the axis inside the shell 1, hooks 509 connected to the outer wall of the rotating rings 503, the screen 4 being configured to have its edge hooked to the hooks 509, the tension of the screen 4 being adjusted by rotating the rotating rings 503, and a pre-screening mechanism 8, the pre-screening mechanism 8 including a screen plate 803 disposed inside the feed inlet 7, the screen plate 803 being configured with a aperture smaller than the maximum standard particle size of electrolytic manganese ultrafine powder, to screen out electrolytic manganese ultrafine powder that does not meet the minimum production standard.

[0022] The outer casing 1 has two fixed rings 501 inside. Multiple rotating seats 502 are arranged around the outer wall of the fixed rings 501 along the axis of the outer casing 1. The outer wall of the rotating seats 502 is slidably connected to the inner wall of the rotating rings 503.

[0023] A toothed ring 506 is slidably connected between two fixed rings 501. Multiple contact rods 505 are arranged around the top outer wall of the toothed ring 506 along the axis of the toothed ring 506. Multiple spiral grooves 504 are opened on the inner wall of the rotating ring 503. The top outer wall of the contact rod 505 contacts the inner wall of the spiral groove 504.

[0024] A gear 507 is rotatably connected to one side of the fixed ring 501 via the block, and a first motor 508 is installed on the outer wall of the bottom of the block. The output end of the first motor 508 is connected to one side of the gear 507.

[0025] Specifically, the teeth on the outer wall of gear 507 mesh with the teeth on the outer wall of gear ring 506, and the top of contact rod 505 meshes with the spiral groove 504 of rotating ring 503. The first motor 508 drives gear 507 to rotate through its output end, and gear 507 drives gear ring 506 to rotate. Contact rod 505 follows the movement of gear ring 506. After the top of contact rod 505 contacts the spiral teeth, the arc-shaped top of contact rod 505 slides along the spiral groove 504 in the spiral groove 504 of rotating ring 503, thereby pushing rotating ring 503 to rotate. Six rotating rings 503 are evenly arranged around the axis of fixed ring 501. The six rotating rings 503 move synchronously. Hooks 509 are connected to the outer wall of rotating ring 503. One end of hook 509 passes through the edge of screen 4. Hook 509 rotates with rotating ring 503. When the six hooks 509 rotate synchronously, they evenly apply or reduce tension on the edge of screen 4, making screen 4 tensile or relaxed, thereby dynamically adjusting the tension of screen 4.

[0026] It should be noted that the selection of the first motor 508 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be elaborated here.

[0027] The top of the feed inlet 7 is connected to a protective shell 807, and the bottom of the protective shell 807 is rotatably connected to a rotating shaft 801. Multiple rotating blades 802 are arranged around the outer wall of the rotating shaft 801 along the axis. The inner wall of the protective shell 807 is connected to a second motor 806, and the output end of the second motor 806 is connected to the top of the rotating shaft 801.

[0028] The top cover 6 is connected to the receiving box 804, and the receiving box 804 is equipped with a baffle 805. The outer wall of one side of the outer shell 1 is connected to the discharge port 2, and the bottom of the outer shell 1 is connected to the base 3.

[0029] Specifically, the blade 802 has a curved side surface. The second motor 806 drives the rotating shaft 801 to rotate through its output end. The rotating shaft 801 drives the blade 802 to rotate. When the electrolytic manganese ultrafine powder to be screened is fed into the feed inlet 7, the high-speed rotating blade 802 uses centrifugal force to throw the electrolytic manganese ultrafine powder to be screened to both sides and crash it into the screen plate 803. The aperture of the screen plate 803 is smaller than the maximum standard particle size for the production of electrolytic manganese ultrafine powder, allowing electrolytic manganese ultrafine powder that meets the production standard to pass through. After passing through the screen plate 803, the electrolytic manganese ultrafine powder that meets the production standard exits from the top of the top cover 6. After passing through the through-holes in the wall, the powder falls onto the screen 4 for further screening. The support box is connected to the screen plate 803 by a snap fastener. Electrolytic manganese ultrafine powder that does not meet the production standards falls along the inner wall of the screen plate 803 to the top of the baffle 805. The angle between the baffle 805 and the horizontal plane is 30 degrees. Electrolytic manganese ultrafine powder that does not meet the production standards slides along the top outer wall of the baffle 805 into the receiving box 804. Electrolytic manganese ultrafine powder is relatively light, and the baffle 805 prevents the collected electrolytic manganese ultrafine powder that does not meet the production standards from being agitated and flowing back when new electrolytic manganese ultrafine powder that does not meet the production standards falls.

[0030] It should be noted that the selection of the second motor 806 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be elaborated here.

[0031] It should be further explained that the buckle mentioned above is a device in the field of mechanical engineering that connects parts through locking components. It uses elastic deformation and friction mechanism to fix the parts. This part is a well-known technology in the field and will not be elaborated here.

[0032] Working principle: During use, the operator starts the second motor 806 and puts the electrolytic manganese ultrafine powder to be screened into the feed port 7. The screening mechanism separates the electrolytic manganese ultrafine powder that does not meet the production standards and collects it in the receiving box 804. The electrolytic manganese ultrafine powder that meets the production standards falls onto the screen 4. According to the actual working conditions and production needs, the operator starts the first motor 508 to adjust the tension of the screen 4. After the tension of the screen 4 is adjusted appropriately, the operator starts the vibrating screen to screen the electrolytic manganese ultrafine powder that meets the production standards. The operator collects electrolytic manganese ultrafine powder of different particle sizes from different discharge ports 2. After screening, the operator removes the receiving box and cleans the electrolytic manganese ultrafine powder that does not meet the production standards from the box. After cleaning, the receiving box is put back in place.
