Description

Technical Field

[0001] This utility model relates to the field of dust removal in cold silos for asphalt mixture preparation, and more particularly to a dust removal mechanism for cold silos for asphalt mixture preparation. Background Technology

[0002] The dust removal mechanism of the cold aggregate bin for asphalt mixture preparation is installed on the cold aggregate bin that stores cold aggregates such as sand and gravel. Through the coordinated work of components such as dust hoods, pipes, fans, dust collectors and dust collection devices, it collects, filters and removes dust such as sand and gravel particles and mineral powder generated in the cold aggregate bin during the loading, unloading, transportation and storage of aggregates, thereby reducing dust diffusion, improving the air quality of the production workshop, reducing pollution, protecting the health of operators and meeting environmental protection regulations.

[0003] When using the dust removal mechanism of the cold aggregate bin for asphalt mixture preparation, first check whether the connections of each component are tight and whether the condition is normal to ensure there is no air leakage or blockage. After starting the system, the fan provides negative pressure power, and the dust generated during the loading, unloading, transportation and storage of aggregates is accurately captured by the dust collection hood near the cold aggregate bin. The dust is transported to the dust collector through pipelines, filtered and separated by filter bags, cyclone separators and other methods. The purified gas is discharged, while the filtered dust is collected in the dust collection device. During operation, parameters such as air pressure and filtration effect need to be monitored regularly to avoid affecting the dust removal efficiency due to blockage. After the operation is completed, the fan is turned off and the dust collection device is cleaned in time to ensure the stable operation of the mechanism for the next use.

[0004] Most dust collectors on the market lack effective separation mechanisms for dust classification and processing, and cannot distinguish between dust of different properties and particle sizes. They often collect all captured dust together, which not only wastes recyclable dust and increases environmental disposal costs, but also reduces resource recycling efficiency because they cannot differentiate the treatment of different types of dust. They require additional investment in sorting and may even fail to meet waste disposal standards. Furthermore, they lack intelligent classification and identification functions, making it difficult to meet the needs of on-demand dust processing in refined production and limiting their integration with resource recycling systems. Therefore, a dust collection mechanism for cold aggregate bins used in asphalt mixture preparation is proposed to solve the above problems. Utility Model Content

[0018] 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.

[0019] Reference Figures 1-3The present invention provides an embodiment of a dust removal mechanism for a cold aggregate bin used in asphalt mixture preparation, comprising a dust collector 1. The dust collector 1 contains a sorting and cleaning mechanism 2 and a periodic collection mechanism 3. The sorting and cleaning mechanism 2 includes an eccentric rotating rod 211, which rotates under the drive of a bidirectional motor 220. This rotation, via a rotating sleeve 229, drives the movement of hinge rod 217 and hinge rod 228, thereby causing the coarse filter screen 221 and the fine filter screen 222 to vibrate. Simultaneously, it drives the helical gear 212 to rotate, providing power for easy cleaning of the filter screens and other cleaning components. Its eccentric design effectively converts rotational motion into vibration and pushing motion. Both ends of the eccentric rotating rod 211 are rotatably connected to the inner wall of the dust collector 1, and a helical gear is fixedly connected to the outer wall of the eccentric rotating rod 211. Helical gear 212 transmits the rotational power of the eccentric rotating rod 211 to helical gear 213, achieving power redirection and ensuring that the rotating rod 214 receives stable rotational power. Helical gear 213 is meshed with the outer wall of helical gear 212. Helical gear 213 receives the power transmitted by helical gear 212 and drives the rotating rod 214 to rotate. This meshing transmission has high transmission efficiency and precision, ensuring stable rotational speed and torque of the rotating rod 214. The rotating rod 214 is fixedly connected to the inner wall of helical gear 213. Driven by helical gear 213, the rotating rod 214 rotates, providing rotational support for the rotating bracket 215 and brush plate 216, allowing the brush plate 216 to rotate around the axis of the rotating rod 214, thus expanding the cleaning range. A rotating bracket 215 is fixedly connected to the outer wall of the rotating rod 214. The rotating bracket 215 connects the rotating rod 214 and the brush plate 216, transmitting the rotational motion of the rotating rod 214 to the brush plate 216. It also fixes and supports the brush plate 216, ensuring it maintains a stable posture during rotation. The brush plate 216 rotates with the rotating bracket 215, cleaning the inner surface of the dust collector 1 above the coarse filter screen 221. This effectively removes impurities adhering to the wall surface, preventing impurity accumulation from affecting the normal operation of the dust collector 1. A rotating sleeve 229 is rotatably connected to the outer wall of the eccentric rotating rod 211. The hinge rod 228 moves under the action of the eccentric rotating rod 211 and the rotating sleeve 229, driving the fine filter... The filter screen 222 vibrates, simultaneously driving the fixed bracket 226 and the circular brush plate 218 to move. A coarse filter screen 221 is connected to the top of the rotating sleeve 229 via a hinge rod 217. The coarse filter screen 221 vibrates under the action of the hinge rod 217, trapping and filtering larger dust particles in the dust-laden gas. The vibration reduces dust adhesion to its surface, improving filtration efficiency. A fine filter screen 222 is connected to the bottom of the rotating sleeve 229 via a hinge rod 228. The fine filter screen 222 vibrates under the action of the hinge rod 228, further trapping and filtering smaller dust particles in the gas after it has been filtered by the coarse filter screen 221. Together with the coarse filter screen 221, it achieves classified filtration of dust. A fixed bracket 226 is fixedly connected to the outer wall of the hinge rod 228.The fixed bracket 226 connects the hinge rod 228 and the circular brush plate 218. Moving with the hinge rod 228, it drives the circular brush plate 218 to perform cleaning work, providing fixation and support for the brush plate 218. The circular brush plate 218 is fixedly connected to the outer wall of the fixed bracket 226. Moving with the fixed bracket 226, the circular brush plate 218 cleans the inner surface of the dust collector 1 between the coarse filter screen 221 and the fine filter screen 222. Its circular structure fits snugly against the inner wall of the dust collector 1, achieving all-around cleaning and reducing dust adhesion. An air inlet pipe 225 is fixedly connected to the outer wall of the dust collector 1. The air inlet pipe 225 is the channel for dust-laden gas to enter the dust collector 1, guiding the gas smoothly into the dust removal area for subsequent filtration.

[0020] Reference Figure 5 , Figure 6 The sorting and cleaning mechanism 2 also includes a fixing plate 227, which provides stable support for the fixing shell 219 and the bidirectional motor 220, enhancing the structural stability of the entire sorting and cleaning mechanism 2. Both sides of the fixing plate 227 are fixedly connected to the inner wall of the dust collector 1. The fixing shell 219 is fixedly connected to the top of the fixing plate 227. The bidirectional motor 220 is fixed inside the fixing shell 219, providing installation and protection space for the bidirectional motor 220, reducing vibration during operation, and ensuring stable operation. A bidirectional motor 220 is fixedly connected to the inner wall of the shell 219. The output shaft of the bidirectional motor 220 is fixedly connected to the eccentric rotating rod 211, serving as a power source to provide power for the rotation of the eccentric rotating rod 211. Its bidirectional rotation characteristic allows adjustment of the rotation direction of the eccentric rotating rod 211 as needed. The output shaft of the bidirectional motor 220 is fixedly connected to one end of the eccentric rotating rod 211 that is close to each other. The sorting and cleaning mechanism 2 includes an air outlet pipe 223, which is the discharge channel for filtered clean gas. Under the suction of the fan 224, the gas is drawn... The gas flow is guided to ensure that the dust-laden gas can pass smoothly through the filter screen. One end of the outlet pipe 223 is fixedly connected to the outer wall of the dust collector 1, and the other end of the outlet pipe 223 is fixedly connected to the fan 224. When the fan 224 is working, it generates suction, which causes the dust-laden gas to enter the dust collector 1 from the inlet pipe 225 and flow towards the outlet pipe 223, providing power for the gas flow in the dust collector 1. One end of the hinge rod 217 is hinged to the outer wall of the rotating sleeve 229. The hinge rod 217 moves under the action of the eccentric rotating rod 211 and the rotating sleeve 229, carrying... The coarse filter 221 vibrates, and its hinged structure makes the motion transmission more flexible and can adapt to the vibration trajectory of the coarse filter 221. The other end of the hinge rod 217 is hinged to the outer wall of the coarse filter 221, and one end of the hinge rod 228 is hinged to the outer wall of the rotating sleeve 229. The hinge rod 228 moves under the action of the eccentric rotating rod 211 and the rotating sleeve 229, which drives the fine filter 222 to vibrate, and at the same time drives the fixed bracket 226 and the circular brush plate 218 to move. The other end of the hinge rod 228 is hinged to the outer wall of the fine filter 222.

[0021] Reference Figure 4 , Figure 7 The periodic collection mechanism 3 includes an electric actuator 311. When the electric actuator 311 is working, it drives the sealing block 312 to slide on the inner wall of the dust collector 1, controlling the opening and closing of the discharge port. Its telescopic movement can precisely control the position of the sealing block 312, ensuring the sealing and opening effect of the discharge port. The top of the electric actuator 311 is fixedly connected to the inner wall of the dust collector 1, and the sealing block 312 is fixedly connected to the inner rod of the electric actuator 311. The sealing block 312 slides under the action of the electric actuator 311, used to seal or open the discharge port. When closed, it can prevent dust leakage, and when open, it can facilitate dust discharge. The outer wall of the cylindrical shell 312 is slidably connected to the inner wall of the dust collector 1. The periodic collection mechanism 3 also includes a cylindrical shell 313. The inner wall of the cylindrical shell 313 is connected to the discharge pipe 314, providing a transition channel for the flow of dust from the discharge port to the discharge pipe 314, guiding the dust smoothly into the discharge pipe 314. The outer wall of the cylindrical shell 313 is fixedly connected to the outer wall of the dust collector 1, and the inner wall of the cylindrical shell 313 is fixedly connected to the discharge pipe 314. The discharge pipe 314 is the channel for dust to enter the collection box 315 from the cylindrical shell 313, guiding the dust to fall accurately into the collection box 315 and preventing the dust from scattering. A collection box 315 is fixedly connected to the end of the feed pipe 314 away from the cylindrical shell 313. The collection box 315 is used to collect dust falling from the discharge pipe 314. Its sliding connection design facilitates removal and cleaning, and enables centralized collection of dust. The outer wall of the collection box 315 is slidably connected to the inner wall of the dust collector 1. The inner wall of the dust collector 1 is elastically connected to a locking pin 317 by a spring 316. The locking pin 317 is engaged with the collection box 315 under the action of the spring 316, fixing the collection box 315. When pulled, the compression spring 316 can disengage the collection box 315, facilitating the collection of dust. For the removal and installation of 5, one end of spring 316 is fixedly connected to the outer wall of locking pin 317. Spring 316 provides elastic force to locking pin 317, so that locking pin 317 can be tightly locked into collection box 315, ensuring the stability of collection box 315 during operation. The other end of spring 316 is fixedly connected to the inner wall of dust collector 1. The periodic collection mechanism 3 also includes handle 318. Handle 318 provides a grip point for the operator, making it convenient to pull collection box 315 for removal and installation, making the operation more convenient and labor-saving. The outer wall of handle 318 is fixedly connected to the outer wall of collection box 315.

[0022] Working principle: The fixed plate 227 is fixed to the inner wall of the dust collector 1, providing stable support for the fixed shell 219. After the bidirectional motor 220 inside the fixed shell 219 is started, the output shaft of the bidirectional motor 220 drives the eccentric rotating rod 211 to rotate on the inner wall of the dust collector 1. The eccentric rotating rod 211, through the rotating sleeve 229, makes the first hinge rod 217 and the second hinge rod 228 respectively hinged to the coarse filter screen 221 and the fine filter screen 222. The rotating eccentric rotating rod 211 causes the second hinge rod 228 to drive the coarse filter screen 221 and the fine filter screen 222 to vibrate, which facilitates the passage of dust through the filter screen and reduces dust adhesion.

[0023] The fixed bracket 226 on the hinge rod 217 moves with the hinge rod 217, driving the circular brush plate 218 to clean the inner wall of the dust collector 1 between the coarse filter screen 221 and the fine filter screen 222. When the eccentric rotating rod 211 rotates, it also drives the helical gear 212 to rotate. The helical gear 212 meshes with the helical gear 213, causing the rotating rod 214 to rotate. The rotating bracket 215 on the rotating rod 214 drives the brush plate 216 to rotate, further cleaning the inner wall of the dust collector 1 above the coarse filter screen 221 to prevent impurities from adhering. The dust-laden gas enters the dust collector 1 from the inlet pipe 225 and flows to the outlet pipe 223 under the suction of the fan 224. When it flows through the coarse filter screen 221 and the fine filter screen 222, dust of different particle sizes is classified and intercepted.

[0024] The filtered dust gradually settles at the bottom of the dust collector 1. When collection is required, the electric actuator 311 drives the sealing block 312 to slide on the inner wall of the dust collector 1, opening the discharge port. The dust vibrates through the discharge port and then enters the discharge pipe 314 through the cylindrical shell 313. It then falls into the collection box 315 from the discharge pipe 314. The collection box 315 is slidably connected to the inner wall of the dust collector 1.

[0025] When there is a lot of dust in the collection box 315, pull the locking pin 317, the spring 316 is compressed, the locking pin 317 disengages from the collection box 315, and the collection box 315 can be pulled out for cleaning by using the handle 318. After cleaning, push the collection box 315 back to its original position, release the locking pin 317, the spring 316 returns to its original position and pushes the locking pin 317 into the collection box 315 to complete the fixation, thus realizing the regular collection and treatment of dust.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
