Therefore, a coal slag dust conveying system is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a coal slag dust conveying system with advantages such as good dust removal effect. It solves the problems of existing dust transfer devices having an open design for the conveyor belt, which cannot effectively prevent coal slag dust from flying and causing serious environmental pollution, and the problem that after long-term use, a large amount of dust often accumulates on the surface of the filter screen, causing filter screen blockage and seriously affecting its filtration efficiency and equipment performance.

[0006] In summary, this application provides the following technical solution: a coal slag dust conveying system, including a controller fixedly installed outside the coal conveying pipeline, a dustproof plate fixedly installed on the upper surface of the coal conveying pipeline, and a slag inlet pipe fixedly connected to the upper surface of the coal conveying channel.

[0007] The conveying mechanism includes a main drive wheel rotatably installed on one side of the coal conveying channel, a driven wheel rotatably installed on the other side of the coal conveying channel, a conveyor belt that is connected to the outside of the main drive wheel and the driven wheel, and a drive motor that is fixedly installed inside the coal conveying channel.

[0008] The dust removal mechanism includes a collection box fixedly installed on the upper surface of the dustproof plate, a horizontal plate set on the upper surface of the collection box, a guide rod fixedly connected to the bottom of the horizontal plate and extending into the inside of the collection box, a filter screen fixedly installed at the bottom end of the guide rod, a fan rotatably installed on the upper surface of the collection box, and a tapping mechanism set on the upper surface of the collection box.

[0009] This application employs the aforementioned technical solution, where a controller activates a fan to create negative pressure inside the collection box, sucking up dust from the coal conveying pipe. The controller then activates a servo motor to drive a cam, which in turn pushes a horizontal plate and guide rod in a reciprocating motion, powerfully beating the filter screen and effectively shaking off dust adhering to it. This prevents dust accumulation and clogging, keeps the filter screen clean, reduces wear from dust particles, and extends its lifespan. The dust is collected in a storage box, achieving excellent dust removal performance. The controller also activates a drive motor to rotate the main and driven wheels, and their connection to the conveyor belt enables continuous conveying of coal slag. This ensures stable transport of coal slag from one end of the coal conveying channel 1 to the other, improving conveying efficiency. The inclined design of the ramp allows the coal slag to slide onto the conveyor belt along a shorter path, further reducing transport time and demonstrating strong practicality.

[0010] Furthermore, the drive motor is fixedly installed inside the coal feeding channel by bolts, the output shaft of the drive motor is fixedly connected to the shaft of the main drive wheel, and the slag inlet pipe is located on the upper surface of the conveyor belt.

[0012] Furthermore, inclined plates are fixedly installed on the inner wall of the coal feeding channel, and the inclined plates are distributed in an inclined manner inside the coal feeding channel and extend to the upper surface of the conveyor belt.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting the inclined plate with an inclined design, the slag can slide onto the conveyor belt along a shorter path during the transportation process.

[0014] Furthermore, the collection box is a hollow cuboid, and a suction pipe is fixedly connected between the collection box and the dustproof plate. A one-way valve is fixedly installed inside the suction pipe.

[0015] The beneficial effect of adopting the above-mentioned further solution is that dust can be collected and treated by setting up a collection box.

[0016] Furthermore, a return spring is fixedly installed at the bottom of the horizontal plate, and the end of the return spring away from the horizontal plate is fixedly connected to the top of the collection box. The return spring is connected around the outside of the guide rod, and there are two sets of both the return spring and the guide rod.

[0018] Furthermore, the tapping mechanism includes a servo motor fixedly mounted on the upper surface of the collection box and a cam fixedly mounted on the output shaft of the servo motor. The cam is rotatably connected to the upper surface of the collection box and abuts against the middle of the horizontal plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the servo motor is started by the controller to drive the cam to rotate, thereby pushing the horizontal plate and the guide rod to move up and down reciprocally.

[0020] Furthermore, the outer diameter of the filter screen is adapted to the inner diameter of the collection box, and the filter screen is oscillatingly connected to the inside of the collection box through a tapping mechanism.

[0021] The beneficial effect of adopting the above-mentioned further solutions is that by keeping the filter clean, the wear and tear of dust particles on the filter can be reduced, further extending the service life of the filter.

[0022] Furthermore, a storage box is slidably connected inside the collection box, and the collection box has a movable opening inside that is adapted to the storage box.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the dust is collected centrally through the storage box, which facilitates subsequent processing and disposal.

[0024] Compared with the prior art, this application provides a coal slag dust conveying system, which has the following beneficial effects:

[0025] 1. This coal slag dust conveying system uses a controller to start a fan, creating negative pressure inside the collection box to suck up dust from the coal conveying pipe. Then, the controller starts a servo motor to drive a cam to rotate, which in turn pushes the horizontal plate and guide rod to move up and down, powerfully beating the filter screen and effectively shaking off the dust attached to it. This prevents dust accumulation and clogging of the filter screen, keeps it clean, reduces wear from dust particles, and extends its service life. The dust is collected in a storage box, achieving excellent dust removal performance.

[0026] 2. This coal slag dust conveying system uses a controller to start the drive motor, which drives the rotation of the main drive wheel and the driven wheel, as well as their transmission connection with the conveyor belt. This enables continuous conveying of coal slag, ensuring that the coal slag can be stably conveyed from one end of the coal conveying channel 1 to the other end, thus improving conveying efficiency.

[0033] Please refer to Figures 1 to 3. In this embodiment, a coal slag dust conveying system includes a controller 2 fixedly installed outside the coal conveying channel 1, a dustproof plate 3 fixedly installed on the upper surface of the coal conveying channel 1, and a slag inlet pipe 4 fixedly connected to the upper surface of the coal conveying channel 1. A conveying mechanism is provided inside the coal conveying channel 1, and a dust removal device is provided on the upper surface of the dustproof plate 3. The conveying mechanism includes a main drive wheel 5 rotatably installed on one side inside the coal conveying channel 1, a driven drive wheel 6 rotatably installed on the other side inside the coal conveying channel 1, a conveyor belt 8 that is connected to the outside of the main drive wheel 5 and the driven drive wheel 6, and a drive motor 7 fixedly installed inside the coal conveying channel 1.

[0034] The drive motor 7 is bolted to the inside of the coal feeding channel 1, and its output shaft is fixedly connected to the shaft of the main drive wheel 5. The slag inlet pipe 4 is located on the upper surface of the conveyor belt 8. The continuous operation of the drive motor 7 ensures the stable rotation of the main drive wheel 5 and the driven wheel 6, thus achieving continuous conveying of coal slag. This continuous operation avoids the efficiency loss caused by intermittent conveying. The tight transmission connection between the main drive wheel 5, the driven wheel 6, and the conveyor belt 8 ensures stable conveying of coal slag and prevents scattering or accumulation of coal slag during the conveying process. The controller 2 starts the drive motor 7, realizing automated control of coal slag conveying. This automated control method reduces the tedium of manual operation and improves work efficiency. The increased level of automation means a reduction in the labor intensity of manual coal slag handling, which helps improve the working environment and health of workers.

[0035] Specifically, inclined plates 9 are fixedly installed on the inner wall of the coal feeding channel 1. These inclined plates 9 are distributed at an angle within the coal feeding channel 1 and extend to the upper surface of the conveyor belt 8. The inclined design of the inclined plates 9 allows coal slag to slide more smoothly onto the conveyor belt 8, reducing the waiting time of the coal slag at the beginning of the conveying process and improving overall conveying efficiency. The inclined design of the inclined plates 9 allows the coal slag to slide onto the conveyor belt 8 along a shorter path. Compared to vertical or horizontal conveying methods, this design significantly shortens the conveying distance, thereby reducing conveying time. A shorter conveying path means less energy consumption and lower equipment wear, which helps reduce the company's operating costs.

[0036] Please refer to Figures 3 and 4. In this embodiment, the dust removal mechanism includes a collection box 10 fixedly installed on the upper surface of the dustproof plate 3, a horizontal plate 13 disposed on the upper surface of the collection box 10, a guide rod 14 fixedly connected to the bottom of the horizontal plate 13 and extending into the inside of the collection box 10, a filter screen 16 fixedly installed at the bottom end of the guide rod 14, a fan 12 rotatably installed on the upper surface of the collection box 10, and a tapping mechanism disposed on the upper surface of the collection box 10.

[0037] The collection box 10 is a hollow cuboid, and a suction pipe 11 is fixedly connected between the collection box 10 and the dustproof plate 3. A one-way valve is fixedly installed inside the suction pipe 11. The operation of the fan 12 creates negative pressure inside the collection box 10, effectively sucking up dust from inside the coal feeding channel 1. This dust collection method can quickly remove dust from the pipes, maintaining a clean working environment. Efficient dust collection reduces the spread of dust in the working area, lowers the impact on worker health, and also reduces the failure rate of equipment due to dust accumulation.

[0038] Specifically, a reset spring 15 is fixedly installed at the bottom of the horizontal plate 13. The end of the reset spring 15 away from the horizontal plate 13 is fixedly connected to the top of the collection box 10. The reset spring 15 is connected around the outside of the guide rod 14, and there are two sets of both the reset spring 15 and the guide rod 14.

[0039] It should be noted that the beating mechanism includes a servo motor 17 fixedly mounted on the upper surface of the collection box 10 and a cam 18 fixedly mounted on the output shaft of the servo motor 17. The cam 18 is rotatably connected to the upper surface of the collection box 10 and abuts against the middle of the horizontal plate 13. The servo motor 17 drives the cam 18 to rotate, pushing the horizontal plate 13 and guide rod 14 to reciprocate up and down, thereby forcefully beating the filter screen 16. This beating method effectively shakes off dust adhering to the filter screen 16, preventing clogging. Keeping the filter screen 16 clean not only prevents clogging caused by dust accumulation but also reduces direct wear from dust particles, thus extending the service life of the filter screen 16. The servo motor 17, as one of the core components of modern automated equipment, features intelligent control. Through programming and a control system, the automated operation and precise control of the beating mechanism can be achieved. Increased automation means reduced manual intervention and operation, lowering the impact of human factors on dust removal efficiency. The dust removal mechanism, by incorporating a servo motor 17, achieves improved dust removal efficiency, extended filter lifespan, optimized dust removal effect, reduced maintenance costs, and increased automation. These advantages make this dust removal mechanism widely applicable in various fields.

[0040] Please refer to Figure 4. In this embodiment, the outer diameter of the filter screen 16 is adapted to the inner diameter of the collection box 10, and the filter screen 16 is oscillatingly connected to the inside of the collection box 10 through a tapping mechanism.

[0041] Referring to Figure 3, in this embodiment, a storage box 19 is slidably connected inside the collection box 10, and the collection box 10 has a movable opening adapted to the storage box 19. Dust is centrally collected through the storage box 19, facilitating subsequent processing and disposal. This centralized collection method prevents dust from scattering in the work area, reducing the difficulty and cost of cleaning. Centralized dust collection and treatment meet environmental protection requirements and help reduce environmental pollution. Simultaneously, by optimizing the vacuuming and cleaning process, energy consumption is reduced, achieving energy-saving effects.

[0042] The working principle of the above embodiments is as follows:

[0043] In operation, the controller 2 starts the drive motor 7, driving the rotation of the main drive wheel 5 and the driven wheel 6, and establishing a transmission connection between them and the conveyor belt 8. This enables continuous conveying of coal slag, ensuring that the coal slag can be stably transported from one end of the coal conveying channel 1 to the other, thus improving conveying efficiency. The inclined plate 9, with its tilted design, allows the coal slag to slide onto the conveyor belt 8 along a shorter path during transport. The controller 2 also starts the fan 12, creating negative pressure inside the collection box 10 to expel dust from the inside of the coal conveying channel 1. The system performs vacuuming, and then the controller 2 activates the servo motor 17 to drive the cam 18 to rotate, which in turn pushes the horizontal plate 13 and guide rod 14 to move up and down reciprocally. This powerfully beats the filter screen 16, effectively shaking off the dust attached to it, preventing dust accumulation and clogging. Keeping the filter screen 16 clean also reduces wear from dust particles, further extending its service life. The dust is collected in a storage box 19 for centralized collection, facilitating subsequent processing and disposal. This centralized collection method avoids dust scattering in the work area, reducing the difficulty and cost of cleaning. The centralized collection and treatment of dust meets environmental protection requirements and helps reduce environmental pollution.
