Description

Technical Field

[0001] This utility model relates to the field of coal chutes technology, specifically to an anti-clogging structure for coal chutes. Background Technology

[0002] Coal chutes are a general term for coal conveying pipelines in industries such as coal mining, ports, thermal power plants, coal storage yards, coal washing plants, and coal-fired industrial boilers. They typically include components such as coal hoppers, downcomers, and diversion troughs. Longer coal chutes may require additional airlocks to reduce dust, and diversion gates may be added when diverting coal.

[0003] When the amount of coal is too large or the coal quality is too moist, it can easily cause the coal flow in the coal chute to be obstructed, which in turn leads to blockage. The conventional way to deal with the blockage of the coal chute is to intervene passively by manually knocking or installing air cannons or air hammers, which wastes a lot of manpower and has very poor effect.

[0004] If the coal at the feed inlet of the coal chute is not promptly and effectively loosened and dispersed, it easily accumulates and compacts, leading to frequent blockages. Blockages in the coal chute directly affect coal conveying efficiency, which in turn impacts the overall production line efficiency. Frequent shutdowns for cleaning blockages are not only time-consuming and labor-intensive but also reduce equipment utilization and overall capacity. Therefore, an anti-blockage structure for the coal chute is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-clogging structure for coal chutes, which has the advantages of being able to agitate the raw coal at the inlet of the coal chute, thus solving the problem of easy clogging at the inlet of the coal chute in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-blocking structure for a coal chuting pipe, comprising a coal chuting pipe, wherein a connecting component for connecting to a coal bunker is provided at the top of the coal chuting pipe, and at least two first linkage components and at least one second linkage component are provided on the pipe body of the coal chuting pipe for connection, and the coal chuting pipe is connected to an installation column through the first linkage component;

[0007] The mounting column is provided with a useful connecting platform, the connecting platform is provided with a connecting spring, the other end of the connecting spring is provided with a mounting plate for installation, and the mounting column is also provided with a vibration motor for transmission.

[0008] The connecting assembly includes a connection port for connecting to the coal chute, a hopper for facilitating coal discharge is provided at the top of the connection port, a corrugated connecting pipe for connection is provided at the top of the hopper, a connecting seat for connecting to the coal bunker is provided at the top of the corrugated connecting pipe, and a planing component for planing the raw coal is provided inside the connecting seat.

[0009] Furthermore, the planing assembly includes at least four support rods fixedly connected to the hopper, and a mounting frame for installation is fixedly connected to the top of the support rods. The top of the mounting frame is provided with multiple planing claws for planing the raw coal.

[0010] Furthermore, the first linkage component includes a first clamp for connecting the coal chute, a first linkage platform is provided on the first clamp, a first linkage spring is provided on the first linkage platform, the other end of the first linkage spring is connected to a first transmission platform, and the first transmission platform is fixedly installed on the mounting column.

[0011] Furthermore, the second linkage component includes a second clamp for connecting the coal chute, a second linkage platform for installation on the second clamp, a second linkage spring on the second linkage platform, a second transmission platform fixedly connected to the other end of the second linkage spring, the second transmission platform fixedly connected to the mounting column, and at least one connecting spring for support on the second linkage platform, the other end of the connecting spring being provided with a linkage seat, the linkage seat being fixedly connected to the mounting column.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] I. The anti-clogging structure for the coal chute is equipped with a first linkage component that can transmit the vibration generated by the vibrating motor to the coal chute, thereby enabling the coal chute to vibrate during the coal chute process and shaking off the coal adhering to the inner wall of the pipe, thus avoiding the situation where the coal sticks to the inner wall of the coal chute due to the moisture of the raw coal.

[0014] Second, the anti-clogging structure used in the coal chute can drive the planing component to vibrate during the vibration of the hopper. During the vibration of the planing component, it can effectively plan the coal at the coal outlet, thereby avoiding the situation where the raw coal at the outlet easily clumps together and accumulates and compacts, leading to blockage.

The structure is characterized by: a connecting component 2 for connection to a coal bunker being provided at the top of the coal chute 1; at least two first linkage components 3 and at least one second linkage component 4 for connection being provided on the body of the coal chute 1; the coal chute 1 being connected to an installation column 11 via the first linkage components 3; a connecting platform 12 being provided on the installation column 11; a connecting spring 13 being provided on the connecting platform 12; an installation plate 14 for installation being provided at the other end of the connecting spring 13; and a vibration motor 15 for transmission being provided on the installation column 11. The connecting component 2 includes a connecting port 21 connected to the coal chuting pipe 1. The top of the connecting port 21 is provided with a feeding hopper 22 for easy coal feeding. The top of the feeding hopper 22 is provided with a corrugated connecting pipe 23 for connection. The top of the corrugated connecting pipe 23 is provided with a connecting seat 24 for connection to the coal bunker. The connecting seat 24 is provided with a planing component 5 for planing the raw coal. The planing component 5 includes at least four support rods 51 fixedly connected to the feeding hopper 22. The top of the support rods 51 is fixedly connected with a mounting frame 52 for installation. The top of the mounting frame 52 is provided with multiple planing claws 53 for planing the raw coal.

[0024] As a preferred technical solution in this embodiment: In actual use, the operator can first install the mounting column 11, which can be installed on the coal bunker support or wall using the mounting plate 14. Then, the operator connects the coal drop pipe 1 to the coal bunker outlet using the connecting component 2. The processing port of the coal drop pipe 1 is then adjusted to the area where coal needs to be dropped. At this point, the operator can control the coal bunker so that the raw coal inside can enter the coal drop pipe 1 through the connecting component 2 and be discharged through the outlet. During this process, the operator can control the vibration motor 15 to... The moving mounting column 11 vibrates. During the vibration of the mounting column 11, the connecting spring 13 provided on the mounting column 11 can effectively realize the connection and ensure the stability of the vibration of the mounting column 11. At the same time, during the vibration of the mounting column 11, the vibration can be transmitted to the coal chute 1 through the first linkage component 3, so that the coal chute 1 can achieve the vibration effect during the coal chute process. During the vibration of the coal chute 1, the coal adhering to its inner wall can be shaken off, avoiding the situation where the coal sticks to the inner wall of the coal chute 1 due to the moisture of the raw coal.

[0025] Furthermore, during the vibration of the coal chute 1, the connection port 21 at its top and the hopper 22 at its bottom can vibrate. During the vibration of the hopper 22, the planing component 5 can vibrate. During the vibration of the planing component 5, the vibration can be transmitted to the mounting frame 52 and the planing claw 53 through the support rod 51, so that the coal at the coal outlet of the coal bunker can be effectively planed, thereby avoiding the situation where the raw coal at the outlet is prone to caking, accumulation and compaction, which can lead to blockage.

[0026] Example 2:

[0027] Please see Figure 1-4 To ensure stable transmission of vibration to the coal chute 1, in this embodiment, the first linkage assembly 3 includes a first clamp 31 for connecting the coal chute 1, a first linkage platform 32 on the first clamp 31, a first linkage spring 33 on the first linkage platform 32, and a first transmission platform 34 connected to the other end of the first linkage spring 33. The first transmission platform 34 is fixedly mounted on the mounting column 11. The second linkage assembly 4 includes a second clamp 41 for connecting the coal chute 1, a second linkage platform 42 for installation on the second clamp 41, a second linkage spring 43 on the second linkage platform 42, a second transmission platform 44 fixedly connected to the other end of the second linkage spring 43, and the second transmission platform 44 fixedly connected to the mounting column 11. The second linkage platform 42 also includes at least one connecting spring 45 for support, and a linkage seat 46 fixedly connected to the other end of the connecting spring 45.

[0028] As a preferred technical solution in this embodiment: In actual use, when the operator can control the vibration motor 15 to drive the installation column 11 to vibrate, the installation column 11 can effectively transmit the vibration to the first transmission table 34 during the vibration process, and then transmit it to the coal drop pipe 1 through the first transmission table 34, thereby driving the coal drop pipe 1 to achieve the vibration effect. Similarly, by adding a second linkage spring 43 and a connecting spring 45 and connecting its two ends to the coal drop pipe 1 and the vibration motor 15 respectively, the vibration transmission of the installation column 11 can be made more stable, avoiding the problem of excessive vibration amplitude caused by the two first linkage components 3 being set far apart.
