Description

Technical Field

[0001] This utility model belongs to the field of ceramsite dust removal technology, specifically relating to a ceramsite dust removal device. Background Technology

[0002] Expanded clay aggregate (ECA) is widely used in various fields such as engineering construction, kitchen and bathroom backfilling, roof insulation, landscaping, sewage treatment, refractory materials, industrial filtration, aquaponics, and sponge city construction. Its raw material sources are extremely diverse, including bauxite, fly ash, clay, shale, garbage, coal gangue, biological sludge, riverbed mud, and fly ash. The processing includes crushing, grinding, metering, mixing, granulation, calcination, cooling, and warehousing of the finished product. Fine dust particles often adhere to the surface of the prepared ECA. When ECA is handled directly, particles are clearly visible on the palm. When large quantities of ECA are piled up, the dust particles on the surface pose a potential risk of dust generation and limit its application scenarios. For example, when ECA with surface dust particles is used in sewage treatment, sponge city construction, or other water-contact applications, the dust particles on the ECA surface are easily washed away by water, leading to water pollution. Therefore, whether a device for drying and removing dust from ECA can be provided is a technical problem that this utility model urgently needs to solve. Utility Model Content

[0003] To address the problems in the background art, this utility model discloses a dust removal device for ceramsite, which combines a dust removal box and electrostatic dust removal to remove dust particles adhering to the surface of ceramsite, thus solving the problem of limited use caused by dust particles adhering to the surface of ceramsite.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: A dust removal device for ceramsite includes a dust collection box with an inlet and a outlet at the top. An outlet and a dust collection port are respectively located at the bottom of the first and second sides of the dust collection box. A dust collection disc is removable at the dust collection port to collect dust from the dust collection box. Multiple filter plates are spaced vertically within the dust collection box, with the filter plates staggered and their free ends inclined downwards. The fixed end of the uppermost filter plate is located below the inlet, and the free end of the lowermost filter plate is located above the outlet. An electric conveyor belt is installed outside the dust collection box. The feed end of the electric conveyor belt extends to the discharge port of the dust collection box, and the discharge end of the electric conveyor belt extends to the finished product packaging and warehousing area. Multiple electrostatic dust removal units are arranged at intervals above the electric conveyor belt along the material conveying direction. The electrostatic dust removal units achieve dust removal of the ceramsite by electrostatic adsorption of fine dust particles on the surface of the ceramsite.

[0005] Furthermore, a bag filter is connected to the dust discharge port.

[0006] Furthermore, each of the electrostatic dust removal units includes an electrostatic dust removal tube, a support and adjustment mechanism, and a drive system. The support and adjustment mechanism includes two first support rods vertically fixed to the ground, and an axially extendable telescopic rod is vertically installed on the upper part of each first support rod. The electrostatic dust removal tube is laterally clamped between the two telescopic rods, and the first end of the electrostatic dust removal tube is connected to the output shaft of the drive motor through a coupling. The second end of the electrostatic dust removal tube is rotatably engaged with the other telescopic rod through a bearing. The drive motor is fixed to the top of the telescopic rod on either side and drives the electrostatic dust removal tube to rotate around its axis.

[0007] Furthermore, multiple friction components are arranged on the electric conveyor belt on the side opposite to the electrostatic dust removal unit. Each friction component includes a second support rod and a friction element. The second support rod is vertically fixed to the ground. The friction element is installed on the top of the support rod, and the working surface of the friction element is parallel to the axis of the electrostatic dust removal pipe.

[0008] Furthermore, the dust collector is also equipped with a discharge plate, a deflector plate, and a discharge channel at its outlet. The discharge plate is fixed at an incline below the dust collector outlet, with its upper end connected to the discharge end of the bottom filter plate. The top of the deflector plate is connected to the inner wall of the dust collector via a hinge shaft, and the middle of the deflector plate is connected to the side wall of the dust collector via a preload spring, forming a swingable elastic guide structure. The discharge channel is formed by a variable gap between the free end of the deflector plate and the discharge plate, and the gap width is dynamically adjusted by the spring preload.

[0009] Furthermore, limit plates are provided on both sides of the electric conveyor belt.

[0010] The beneficial effects of this utility model are as follows: This device features a feed inlet and discharge outlet at the top of the dust collection chamber, and discharge outlets and dust collection outlets at the bottom of both sides, creating a scientific material flow path. Dust is more easily guided by gravity and airflow to settle into the dust collection area, preventing secondary dust re-entrainment and significantly improving dust removal efficiency. Compared to the potential airflow turbulence or dust backflow problems of traditional dust collection equipment, this design is more in line with fluid mechanics principles, enhancing overall dust removal performance.

[0011] The dust collection tray features a pull-out design, making dust collection and cleaning more convenient. This design solves the problems of difficult dust removal, high maintenance frequency, and cumbersome operation in traditional dust removal equipment, reducing labor and time costs. At the same time, the pull-out structure also facilitates regular inspection of the dust removal system's internal condition, preventing dust accumulation and blockages that could affect equipment operation.

[0012] This application utilizes a rationally designed dust outlet location and a highly efficient dust collection tray to effectively curb dust leakage and reduce air pollution in the working environment. It is particularly suitable for scenarios where large amounts of dust are generated during the processing of ceramsite, helping enterprises meet national environmental emission standards, improve the quality of the factory environment, and align with the current development trends of "green manufacturing" and "clean production."

Detailed Implementation

[0016] To better understand this utility model, the following embodiments further illustrate its content. However, the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be implemented without one or more of these details. It should be noted that the innovation of this utility model lies in the structure of the ceramsite drying and dust removal device. The control method of the ceramsite drying and dust removal device during operation employs existing technology and is not the subject of protection of this utility model; therefore, it will not be described in detail here.

[0017] Example The following is in conjunction with the appendix Figure 1-6 This invention provides a detailed description of a dust removal device for ceramsite, comprising a dust collection box 1. An inlet 2 and a dust outlet 3 are provided at the top of the dust collection box 1. A bag filter 4 is connected to the dust outlet 3 to absorb dust within the dust collection box 1. An outlet 5 and a dust collection port 6 are respectively provided at the bottom of the first and second sides of the dust collection box 1. A dust collection disc 7 is removable at the dust collection port 6 to collect dust from the dust collection box 1. Multiple filter plates 8 are arranged vertically and vertically within the dust collection box 1, with the filter plates 8 staggered and their free ends inclined downwards to ensure that the ceramsite moves towards the outlet 5 of the dust collection box 1 under gravity. The fixed end of the uppermost filter plate 8 is located below the inlet 2, and the free end of the lowermost filter plate 8 is located above the outlet 5.

[0018] An electric conveyor belt 9 is installed outside the dust collection box 1. The inlet end of the electric conveyor belt 9 extends to the outlet 5 of the dust collection box 1, and the outlet end of the electric conveyor belt 9 extends to the finished product packaging and warehousing. Multiple electrostatic dust removal units are arranged at intervals above the electric conveyor belt 9 along the material conveying direction. The electrostatic dust removal units achieve dust removal of the ceramsite by electrostatic adsorption of fine dust particles on the surface of the ceramsite.

[0019] During operation, the ceramsite blanks enter the dust collection box 1 through the feed inlet 2 and fall onto the top filter plate 8. Under the influence of gravity, they pass through different filter plates 8 from high to low, and are finally conveyed to the discharge port 5. During the movement on the filter plates 8, some of the dust on the ceramsite detaches and suspends in the air, and then flows through the dust discharge port 3 into the bag filter 4 for preliminary dust removal. Another part of the dust falls onto the dust collection tray 7 at the bottom of the dust collection box 1. After a certain period of time, the dust collection tray 7 can be pulled out at the dust collection port 6 to clean off the dust it has collected. After preliminary dust removal, the ceramsite is discharged from the discharge port 5 and conveyed to the sub-packaging and warehousing area via the electric conveyor belt 9. During the conveying process on the electric conveyor belt 9, the electrostatic dust removal tube 10 achieves deep dust removal of the ceramsite by electrostatic adsorption of fine dust particles on the surface of the ceramsite.

[0020] Each electrostatic precipitator unit includes an electrostatic precipitator tube 10, a support and adjustment mechanism, and a drive system. The support and adjustment mechanism includes two vertically fixed first support rods 11, each first support rod 11 with an axially extendable telescopic rod 12 vertically mounted on its upper part. The telescopic rod 12 is electrically operated. The electrostatic precipitator tube 10 is laterally clamped between the two telescopic rods 12, and the first end of the electrostatic precipitator tube 10 is connected to the output shaft of a drive motor 13 via a coupling. The second end of the electrostatic precipitator tube 10 is rotatably engaged with the other telescopic rod 12 via a bearing. The drive motor 13 is fixed to the top of the telescopic rod 12 on either side and drives the electrostatic precipitator tube 10 to rotate around its axis. In this application, the telescopic rods 12 located at both ends of the same electrostatic dust removal tube 10 can be connected to a synchronous controller so that the displacement changes of the two telescopic rods 12 are the same, thereby realizing the synchronous movement of both ends of the electrostatic dust removal tube 10; in addition, the electrostatic dust removal tube 10 located directly above the electric conveyor belt 9 rotates under the drive of the drive motor 13, and can electrostatically adsorb the fine dust particles on the surface of the ceramic particles on the electric conveyor belt 9.

[0021] Multiple friction components are arranged on the electric conveyor belt 9 on the side opposite to the electrostatic dust removal unit. Each friction component includes a second support rod 14 and a friction element 15. The second support rod 14 is vertically fixed to the ground. The friction element 15 is installed at the top of the support rod, and the working surface of the friction element 15 is parallel to the axis of the electrostatic dust removal pipe 10. In this embodiment, a conductive fiber composite brush can be used as the friction element 15, which can make the surface of the dust removal pipe negatively charged through the triboelectric effect. At the same time, the elastic deformation of the fiber can penetrate into the groove of the pipe wall to clean the dust. The conductive fiber brush in this application can be made of carbon fiber blend with moderate surface resistivity, which can conduct away the charge and avoid excessive accumulation of electrostatic field. In addition, the physical scraping force generated by the elastic deformation of the fiber is much greater than the electrostatic adsorption force, and the dust removal effect is higher than the risk of re-adsorption. Therefore, the dust scraped off the fiber brush can be minimized or even avoided from being re-adsorbed back onto the electrostatic dust removal pipe 10. The shape of the friction element 15 can be a single rod, an inclined straight plate, or an arc plate, as long as it can achieve the scraping and friction of the electrostatic dust removal pipe 10. As an optimization measure, a pressure sensor can be installed on the contact surface between the friction element 15 and the electrostatic precipitator tube 10 to monitor whether the electrostatic precipitator tube 10 contacts the friction element 15, thereby further controlling the extension and stopping of the telescopic rod 12. After the electrostatic precipitator tube 10 rotates and removes dust above the electric conveyor belt 9 for a certain period of time, the telescopic rod 12 extends, causing the electrostatic precipitator tube 10 to move towards the friction element 15 until it contacts the friction element 15. The pressure sensor then sends feedback to the telescopic rod 12, at which point the telescopic rod 12 stops extending. The rotating electrostatic precipitator tube 10 rubs against the friction element 15, removing dust from the electrostatic precipitator tube 10. After the electrostatic precipitator tube 10 contacts and rubs against the friction element 15 for 3-5 seconds, the telescopic rod retracts, causing the electrostatic precipitator tube 10 to retract above the electric conveyor belt 9, awaiting the next stage of dust removal operation. All telescopic rods 12 mentioned above are electric telescopic rods of the same model.

[0022] The dust collector 1 is also provided with a discharge plate 16, a deflector plate 17, and a discharge channel 18 at the discharge port 5. The discharge plate 16 is inclined and fixed below the discharge port 5 of the dust collector 1, and the high end of the discharge plate 16 is connected to the discharge end of the bottom filter plate 8. The top end of the deflector plate 17 is connected to the inner wall of the dust collector 1 through a hinge shaft, and the middle part of the deflector plate 17 is connected to the side wall of the dust collector through a preload spring 19, forming a swingable elastic guide structure. The discharge channel 18 is formed by the variable gap between the free end of the deflector plate 17 and the discharge plate 16, and the gap width is dynamically adjusted by the preload force of the spring 19.

[0023] Limit plates 20 are installed on both sides of the electric conveyor belt 9 to prevent the ceramic particles from falling off the sides of the electric conveyor belt 9.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
