Abstract
Description
Technical Field
[0001] This utility model relates to the field of toner cartridge technology, and in particular to a toner cartridge anti-clogging device. Background Technology
[0002] Carbon injection in electric arc furnace (EAF) smelting is a modern smelting technology that increases the carbon content in the furnace by injecting carbon powder or other carbon-containing compound powders during the EAF smelting process, thereby raising the furnace temperature and recovering heat energy. In the EAF carbon powder injection process, the carbon powder silo is a key piece of equipment, its main function being to store and transport carbon powder to enable the injection operation. The carbon powder silo is typically used to store the carbon powder for injection, which can be injected directly into the steelmaking furnace via small bags or an air compressor.
[0003] In existing technologies, due to the high adhesiveness and hygroscopicity of toner, it is prone to moisture absorption and clumping when stored in toner silos for extended periods, forming stable arched structures that lead to poor material flow or even complete blockage. Traditional solutions often employ simple mechanical vibration or manual unclogging, which are not only ineffective but also pose safety hazards. Especially in high-humidity environments, toner is more likely to adhere and accumulate on the silo walls. Furthermore, existing toner silos mostly employ fixed structures and lack effective internal unblocking mechanisms. Severe clogging necessitates machine shutdown and manual cleaning, increasing maintenance costs and reducing production efficiency. Therefore, we propose a toner silo anti-clogging device to address these issues. Utility Model Content

A rotating ring is fixedly connected to the outer wall of the convex ring. A toothed ring is fixedly sleeved on the outer wall of the convex ring. Two anti-clogging scrapers are fixedly connected to the top of the rotating ring. A bottom frame is fixedly connected to the bottom of the docking ring. A drive assembly is provided inside the bottom frame. A material pipe is fixedly connected to the bottom of the docking ring.

By setting the drive assembly, the transmission shaft is driven to rotate, thereby causing the gear to drive the gear ring to rotate.
[0008] Preferably, a cover is placed on the top of the silo body, and a flange is fixedly connected to the bottom of the material pipe. The flange is used for pipe connection. After the toner falls into the pipe, it is blown into the electric furnace by an existing air compressor and compressed airflow.

[0010] Preferably, the outer walls of both anti-clogging scrapers are slidably connected to the inner wall of the container, and a connecting rod is fixedly connected between the two anti-clogging scrapers to increase the connection strength between the two anti-clogging scrapers.
[0011] Preferably, the outer wall of the docking ring has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the geared motor.
[0012] Preferably, a bearing is fixedly sleeved on the outer wall of the drive shaft, and the outer ring of the bearing is fixedly connected to the inner wall of the mating ring. The drive shaft is stabilized by setting the bearing.
[0013] Compared with the prior art, the advantages of this utility model are:

[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. 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.
[0022] Depend on Figures 1-4 As shown, a toner hopper anti-clogging device is disclosed, comprising a hopper body 1, a hopper cover 2 placed on the top of the hopper body 1, the hopper cover 2 adopting a hinged opening structure and equipped with an observation window for easy inspection of the internal condition, a hollow docking ring 3 fixedly connected to the bottom of the hopper body 1, an annular groove opened on the inner wall of the docking ring 3, a convex ring 4 rotatably connected to the inner wall of the annular groove, a rotating ring 5 fixedly connected to the outer wall of the convex ring 4, the outer wall of the rotating ring 5 slidingly connected to the inner wall of the docking ring 3, and a toothed ring 6 fixedly sleeved on the outer wall of the convex ring 4.
[0023] Two anti-clogging scrapers 7 are fixedly connected to the top of the rotating ring 5. The outer walls of both anti-clogging scrapers 7 are slidably connected to the inner wall of the chamber 1. A connecting rod 8 is fixedly connected between the two anti-clogging scrapers 7. The rigid frame structure formed by the two anti-clogging scrapers 7 and the connecting rod 8 moves in a circular motion along the inner wall of the chamber 1 under the drive of the rotating ring 5. The anti-clogging scrapers 7 are made of wear-resistant alloy steel with a hard chrome plating, which can effectively break up the formed carbon powder arching. The design of the connecting rod 8 enhances the overall rigidity, allowing the anti-clogging scrapers 7 to apply greater shear force and completely destroy the adhesion between the powder particles.
[0024] A bottom frame 9 is fixedly connected to the bottom of the docking ring 3. A material pipe 13 is fixedly connected to the bottom of the docking ring 3. A dual rotor metering valve 14 (QSZV) is fixedly installed on the outer wall of the material pipe 13. The dual rotor metering valve 14 (QSZV) is made of stainless steel and the rotor surface is polished. A flange 15 is fixedly connected to the bottom of the material pipe 13.
[0025] The bottom frame 9 is equipped with a drive assembly, which includes a geared motor 10. The outer wall of the docking ring 3 has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the geared motor 10. The inner wall of the bottom frame 9 is fixedly connected to the bottom of the geared motor 10.
[0026] A drive shaft 11 is fixedly connected to the top of the output shaft of the geared motor 10. The drive shaft 11 adopts a bearing support structure to ensure long-term stable operation in the powder environment. A bearing is fixedly sleeved on the outer wall of the drive shaft 11. The outer ring of the bearing is fixedly connected to the inner wall of the mating ring 3. The bearing is a tapered roller bearing. A gear 12 is fixedly sleeved on the outer wall of the drive shaft 11. The gear 12 is meshed with the gear ring 6.
[0027] Working principle: During use, open the hopper cover 2 and add toner into the hopper body 1. During conveying, the geared motor 10 drives the drive shaft 11 to rotate. The drive shaft 11 rotates, which in turn drives the connected gear 12 to rotate. The gear 12 rotates, which in turn drives the gear ring 6 to rotate. The gear ring 6 rotates, which in turn drives the convex ring 4 and the rotating ring 5 to rotate. The rotating ring 5 rotates, which in turn drives the two anti-blocking scrapers 7 to rotate. The rotation of the anti-blocking scrapers 7 disperses the toner in the hopper body 1, preventing bridging and facilitating toner feeding. As the dual rotor metering valve 14 rotates, it measures the toner. After measurement, the dual rotor metering valve 14 stops operating, and the measured toner is conveyed downward through the feed pipe 13. The toner can be conveyed through existing air compressors and pipelines.
[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 10 and the dual rotor metering valve 14 to facilitate the control of the overall operation.
