Description

Technical Field

[0001] This utility model relates to the field of coal chutes technology, and in particular to a coal chute assembly with air circulation function. Background Technology

[0002] With increasing coal demand, coal transportation efficiency has become a critical issue, especially since coal accumulation and blockages during transport often affect production stability and efficiency. To improve the efficiency and stability of coal transportation systems, coal chutes with air-draining capabilities have emerged. By improving coal flowability and reducing accumulation and blockages within the pipes, this technology effectively enhances transportation efficiency, reduces maintenance requirements, and minimizes the risk of production downtime. With advancements in intelligent and automated technologies, air-draining functionality will play an even more vital role in coal transportation systems, further enhancing their efficiency and safety, and becoming a key technology in the coal transportation sector.

[0003] A search revealed an existing patent (publication number: CN214745880U) disclosing a three-section anti-clogging coal chute assembly with air venting function, relating to the field of coal chute technology. This utility model includes a first rectangular tube, a second rectangular tube, and a conical tube; the bottom end of the first rectangular tube is connected to the top end of the second rectangular tube, forming a first air outlet; the bottom end of the second rectangular tube is connected to the top end of the conical tube, forming a second air outlet; and an inclined coal outlet is opened at the bottom end of the conical tube. This utility model uses the first rectangular tube, the second rectangular tube, and the conical tube connected in sequence to form a coal chute. Air chambers are installed at the connection points between the first and second rectangular tubes and between the second rectangular tube and the conical tube, and purging air is introduced at the bottom end of the conical tube. Utilizing a three-section primary air purging method, it achieves airflow stability and directional coal flow, effectively reducing the degree of coal blockage in the coal chute and the enterprise's maintenance costs, while also alleviating labor pressure; thus improving the enterprise's economic benefits and personnel safety.

[0004] However, in actual use, the above solution cannot accurately adjust the airflow according to the coal flow, resulting in wasted air when the coal flow is smooth, and insufficient airflow to help clear the blockage when the flow is obstructed, thus affecting the clearing effect. Secondly, the fixed size of the air outlet cannot adapt to different coal conditions (such as particle size, humidity, etc.), reducing the system's adaptability and flexibility. In addition, inaccurate airflow will lead to reduced efficiency, and there may be too much or too little airflow, thus wasting energy and increasing energy consumption.

[0005] Therefore, this utility model provides a coal chute assembly with air circulation function. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that the air flow rate cannot be precisely adjusted according to the coal flow, resulting in air waste when the coal flow is smooth and insufficient airflow to help clear the blockage when the flow is not smooth, thus affecting the clearing effect. Therefore, this invention proposes a coal drop pipe component with air clearing function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A coal chute assembly with air venting function includes a second conical pipe, and further includes:

[0012] The unblocking component is located at the end of the coal conveying pipe near the second conical pipe.

[0013] The air outlet adjustment component is located at the air outlet end of the unblocking component.

[0014] As a preferred technical solution of this application, the rotating assembly includes a toothed ring fixed to the outer wall of the top of the second conical tube, a limiting frame rotatably connected to the outer side of the toothed ring, a motor fixedly connected to the bottom of the outer side of the limiting frame, a drive gear on the inner side of the limiting frame near the limiting frame, a transmission gear rotatably connected to the inner side of the middle section of the limiting frame, the drive gear fixedly connected to the output end of the motor, the drive gear meshing with the transmission gear, the toothed ring meshing with the transmission gear, and a limiting ring symmetrically fixedly connected to the inner side of the limiting frame, the limiting ring being rotatably connected to the toothed ring.

[0015] As a preferred technical solution of this application, the jacking pipe assembly includes a support plate fixed to the outer side of the top of the limiting frame, and a first tapered pipe is fixedly connected to the top of the support plate.

[0016] As a preferred technical solution of this application, the unblocking component includes an oblique tee fixed to the bottom of the second conical pipe, and an air cannon is fixedly connected to the outer side of the oblique tee on the side away from the coal conveying pipe.

[0017] As a preferred technical solution of this application, the air inlet adjustment assembly includes a fixed pipe fixed to the output end of the air cannon, a uniformly distributed hydraulic rod rotatably connected to the outside of the fixed pipe, a transmission ring rotatably connected to the output end of the hydraulic rod, a transmission rod rotatably connected to the bottom of the transmission ring, a guide plate rotatably connected to the bottom end of the transmission rod, and the guide plate rotatably connected to the bottom of the fixed pipe.

[0019] Compared with the prior art, this utility model provides a coal chute assembly with air circulation function, which has the following beneficial effects:

[0020] 1. The coal chute assembly with airflow control function described in this utility model adjusts the airflow velocity by regulating the output port size of the air cannon through an air outlet adjustment component. This allows for real-time adjustment of the airflow based on the specific coal flow conditions, optimizing the dredging effect and preventing excessive or insufficient airflow. Secondly, the adjustment function adapts to the characteristics of different coals, improving the system's flexibility and adaptability, and ensuring good working conditions in various conveying environments. Furthermore, precise airflow velocity adjustment helps improve conveying efficiency, reduce energy waste, and lower operating costs.

[0021] 2. The coal conveying pipe assembly with air-clearing function described in this utility model adjusts the output angle of the coal conveying pipe by rotating the assembly to move the second conical tube at the bottom. This optimizes the coal flow path, prevents blockages or accumulation, and improves conveying efficiency. Simultaneously, adjusting the output angle better matches the coal flow direction and air velocity, ensuring more efficient air-clearing and improving the clearing effect. Furthermore, this adjustment enhances the system's adaptability, accommodating different coal characteristics and conveying environments, reducing problems caused by environmental changes.
