Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon screening equipment, and in particular to an activated carbon specific gravity vibrating screen stone removal mechanism. Background Technology

[0002] Activated carbon is a carbonaceous adsorbent material with a highly developed pore structure, made from carbonaceous materials such as wood, coal, and nutshells through carbonization and activation. However, during the collection, transportation, or pretreatment of these natural raw materials, impurities such as stones are inevitably mixed in. If these stones remain in the finished activated carbon product, they will not only reduce its purity but also easily cause adverse effects on subsequent use or processing equipment.

[0003] Therefore, cleaning is usually achieved using vibrating equipment, such as a rotary vibrating screen, which typically has a dust cover with a feed inlet. When the rotary vibrating screen is working, the vibrations loosen the material and create stratification: heavier stones, due to the combined effects of gravity and vibration, settle more quickly to the lower layer or below the screen and are separated; while lighter activated carbon particles remain above the screen or are graded according to particle size. This process effectively separates activated carbon from stone impurities, thereby improving the purity of the activated carbon.

[0004] However, when using a traditional rotary vibrating screen, the material must first be poured in through the feed inlet. If too much material is poured in at once, the screen surface will accumulate too thickly, disrupting the fluidized stratification. The vibration energy will be offset by the weight of the material itself, resulting in the activated carbon and stones not being effectively separated according to their specific gravity. This not only leads to incomplete stone removal but also easily clogs the screen. If too little material is poured in at once, the screen surface utilization rate will be low, vibration energy will be wasted, the processing capacity per unit time will drop sharply, the equipment will suffer significant idling losses, and the efficiency will be greatly reduced. Utility Model Content

[0005] The purpose of this invention is to address the problems of traditional vibrating screens where excessive material input leads to excessively thick screen surface accumulation, resulting in poor separation effect and easy screen blockage; and where insufficient material input leads to low screen surface utilization and reduced efficiency. This invention proposes a stone-removing mechanism for activated carbon specific gravity vibrating screens.

[0006] The technical solution of this utility model is as follows: an activated carbon specific gravity vibrating screen stone removal mechanism, including a rotary vibrating screen and a dust cover installed on the top of the rotary vibrating screen. The dust cover has a feed inlet in the middle. It also includes: a support cover installed on the top of the feed inlet. The inside of the support cover is provided with a rotating mechanism for quantitatively pouring material into the rotary vibrating screen; a cover plate fixedly connected to the top of the support cover, and the upper surface of the cover plate is provided with a drive mechanism for running the rotating mechanism.

[0007] Optionally, the rotating mechanism includes a central block rotatably connected to the middle of the support cover. The central block has a plurality of receiving holes arranged in a circumferential array inside. The bottom of the support cover has a discharge port fixedly connected to the top of the feed inlet. The discharge port coincides with the bottom of the receiving holes.

[0008] Optionally, the driving mechanism includes an L-shaped bracket fixedly connected to the upper surface of the cover plate. A servo motor is fixedly connected to the upper surface of the L-shaped bracket. The output shaft of the servo motor passes through the L-shaped bracket and is fixedly connected to a first gear. The end of the first gear away from the servo motor is rotatably connected to the cover plate. A second gear is provided in the middle of the cover plate and meshes with the first gear. A connecting rod is fixedly connected to the end of the second gear near the cover plate. The connecting rod passes through the cover plate and is fixedly connected to the center block.

[0009] Optionally, the cover plate has a feed hole that coincides with the top of the receiving hole, and the feed hole and the discharge port are offset from each other and have the same diameter.

[0010] Optionally, the upper surface of the cover plate is provided with a storage bin, and the bottom end of the storage bin is fixedly connected to the feed hole.

[0011] Optionally, both ends of the receiving hole are provided with silicone pads that are tightly connected to the support cover and the cover plate.

[0012] Optionally, the internal diameter of the receiving hole is the same as that of the discharge port and the feed hole.

[0013] Optionally, the length of the connecting rod is set to be the same as the thickness of the cover plate.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes a storage bin, a rotating mechanism, a drive mechanism, and supporting components. When using a vibrating screen, material is stored in the storage bin. A servo motor drives a gear to rotate the central block. Material from the storage bin enters the central block's receiving hole through the feed hole and, as the central block rotates, falls quantitatively into the vibrating screen through the discharge port. The vibration of the vibrating screen causes activated carbon and stones to separate into layers according to their specific gravity, thus cleaning the stones. This quantitative feeding ensures a suitable material thickness on the screen surface, maintains good fluidization and stratification, fully utilizes vibration energy, ensures thorough stone cleaning without clogging the screen, improves screen surface utilization, reduces energy consumption, and increases processing capacity and efficiency per unit time.

[0028] Example

[0029] like Figures 1 to 5 As shown, the activated carbon specific gravity vibrating screen cleaning mechanism proposed in this utility model includes a rotary vibrating screen 1 and a dust cover 11 installed on top of the rotary vibrating screen 1. A feed inlet 12 is provided in the middle of the dust cover 11, serving as the channel for material to enter the rotary vibrating screen 1, and is connected to the discharge port 21 of the support cover 2. The support cover 2 is installed on top of the feed inlet 12, providing installation and support space for the internal rotating mechanism, and forming a closed structure with the cover plate 24. The cover plate 24 is fixedly connected to the top of the support cover 2, providing an installation base for the drive mechanism, and has a feed hole 25 for material entry.

[0030] Among them, such as Figures 3 to 4As shown, the support cover 2 has a rotating mechanism inside that allows material to be quantitatively poured into the vibrating screen 1. The rotating mechanism includes a central block 22 rotatably connected to the middle of the support cover 2. The central block 22 has material receiving holes 23 inside, and the rotation enables quantitative material conveying. The central block 22 has multiple material receiving holes 23 arranged in a circumferential array inside, with three holes 23 on the central block 22. The material receiving holes 23 are located inside the central block 22 and arranged in a circumferential array to receive and convey material. Silicone gaskets at both ends ensure a leak-proof seal. Both ends of the material receiving holes 23 are equipped with silicone gaskets that are tightly connected to the support cover 2 and the cover plate 24. The silicone gaskets have excellent elasticity and sealing properties, are wear-resistant, high-temperature resistant, and chemically stable, and can adapt to the vibration environment during activated carbon screening, effectively preventing material leakage from the gaps between the material receiving holes and the support cover and cover plate. Simultaneously, their flexibility reduces hard friction between components, making them suitable for solid materials in long-term contact with activated carbon. The internal diameter of the receiving hole 23 is the same as that of the discharge port 21 and the feed port 25. The bottom of the support cover 2 has a discharge port 21 that is fixedly connected to the top of the feed port 12. The discharge port 21 is located at the bottom of the support cover 2 and is fixedly connected to the top of the feed port 12. It serves as the channel for material to enter the vibrating screen 1 from the support cover 2, and it coincides with the bottom end of the receiving hole 23. The discharge port 21 and the bottom end of the receiving hole 23 are aligned.

[0031] In addition, such as Figures 1 to 3 As shown, the upper surface of the cover plate 24 is equipped with a drive mechanism for operating the rotating mechanism. The drive mechanism includes an L-shaped bracket 26 fixedly connected to the upper surface of the cover plate 24. A servo motor 27 is fixedly connected to the upper surface of the L-shaped bracket 26. The servo motor 27 achieves precise rotation of 120 degrees each time, ensuring that after each rotation of the receiving hole 23, the upper and lower ends of the receiving hole 23 coincide with the corresponding discharge port 21 and feed port 25. The servo motor 27 rotates 120 degrees each time, which relies on closed-loop control and pulse command conversion. In use, the controller converts the 120-degree target angle into the corresponding number of pulses (approximately 1365 pulses per 120 degrees) according to the motor encoder resolution (e.g., 4096 pulses per revolution) and sends it to the servo driver. The driver drives the servo motor 27 to rotate, while the encoder detects the rotor position in real time and feeds back pulses. The driver compares the target and actual pulses, adjusts the output through a PID algorithm, corrects the deviation, until the servo motor 27 stops precisely at the 120-degree position, achieving high-precision positioning. This process utilizes a closed-loop logic of "instruction-execution-feedback-correction" to ensure precise angle measurement. The output shaft of the servo motor 27 passes through the L-shaped bracket 26 and is fixedly connected to a first gear 28. The first gear 28 is fixed to the output shaft of the servo motor 27 and meshes with a second gear 29, transmitting power from the servo motor 27 to the second gear 29. The end of the first gear 28 furthest from the servo motor 27 is rotatably connected to the cover plate 24.

[0032] It is worth noting that, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a second gear 29 is provided in the middle of the cover plate 24, meshing with the first gear 28. The second gear 29 meshes with the first gear 28, and drives the central block 22 to rotate through the connecting rod 291, thus transmitting power. The connecting rod 291 is fixedly connected to one end of the second gear 29 near the cover plate 24. One end of the connecting rod 291 is fixedly connected to the second gear 29, and the other end passes through the cover plate 24 and is fixed to the central block 22, transmitting the rotational motion of the second gear 29 to the central block 22. The connecting rod 291 movably passes through the cover plate 24 and is fixedly connected to the central block 22. The length of the connecting rod 291 is the same as the thickness of the cover plate 24.

[0033] Furthermore, such as Figure 3 As shown, the cover plate 24 has a feed hole 25 that coincides with the top of the receiving hole 23. The feed hole 25 is located on the cover plate 24 and coincides with the top of the receiving hole 23. It is the channel for material to enter the receiving hole 23 from the storage bin 3. It is offset from the discharge port 21 and has the same diameter. The feed hole 25 and the discharge port 21 are offset from each other and have the same diameter.

[0034] Furthermore, such as Figures 1 to 3 As shown, a storage bin 3 is provided on the upper surface of the cover plate 24. The storage bin 3 is located on the upper surface of the cover plate 24, and its bottom end is fixedly connected to the feed hole 25. It is used to store the material to be screened and ensure a continuous supply of material. The bottom end of the storage bin 3 is fixedly connected to the feed hole 25.

[0035] In this embodiment, when using the activated carbon specific gravity vibrating screen stone removal mechanism, the activated carbon material to be screened is first placed into the storage bin 3, and the material enters the receiving hole 23 through the feed hole 25 on the cover plate 24. The servo motor 27 is started, and the output shaft of the servo motor 27 drives the first gear 28 to rotate. The second gear 29, which meshes with the first gear 28, rotates accordingly. Through the connecting rod 291, the central block 22 is driven to rotate inside the support cover 2, and the receiving hole 23 inside the central block 22 rotates synchronously.

[0036] When the receiving hole 23 rotates to align with the feed hole 25, the material falls into the receiving hole 23; when it continues to rotate to align with the discharge port 21 at the bottom of the support cover 2, the material enters the vibrating screen 1 through the discharge port 21 and the feed port 12 of the vibrating screen 1. During this process, the silicone pads at both ends of the receiving hole 23 ensure a tight fit with the support cover 2 and the cover plate 24 to prevent material leakage, and the rotation achieves quantitative and uniform feeding of the material.

[0037] The vibrating screen 1 vibrates during operation, causing the material to loosen and stratify. The heavier stones settle to the lower layer and separate, while the lighter activated carbon remains above the screen, completing the stone removal and screening process. The dust cover 11 serves to prevent dust and leakage, and the L-shaped bracket 26 fixes the servo motor 27 to ensure structural stability.

[0038] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
