Description

Technical Field

[0001] This utility model relates to the field of thermal power plants, specifically to an anti-clogging coal drop pipe for thermal power plants. Background Technology

[0002] Coal chutes are pipeline equipment used to transport coal in industries such as thermal power plants, coal mines, ports, thermal power plants, coal transfer and storage stations, coal washing plants, and coal-fired industrial boilers. Coal chutes are coal transport components in the coal transport system of thermal power plants. There is a drop between the raw coal bunker and the coal mill. The function of the coal chutes is to transport raw coal from the raw coal bunker to the coal mill, transferring coal from a high place to a low place.

[0003] When transporting coal, the existing coal chute has a drawback: because the chute is a continuous structure, the accumulated coal is prone to causing blockages at the bends of the pipe, and the coal cannot be effectively dropped by its own weight. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes an anti-blocking coal chuting pipe for thermal power plants, which features increased impact force of falling coal and a built-in vibration mechanism to prevent pipe blockage.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, this utility model provides an anti-blocking coal chuting pipe for thermal power plants, including a coal chuting pipe, a partition plate installed in the middle of the coal chuting pipe, and the ends connected to a first branch pipe and a second branch pipe respectively.

[0008] The coal dropping mechanism includes a drive motor installed on the first branch pipe, a drive shaft installed at the output end of the drive motor, a bushing sleeve fitted on the outer wall of the drive shaft, and a flap that separates the transmission channel of the first branch pipe installed on the bushing.

[0009] The vibration mechanism includes a vibration motor installed on the first branch pipe. The output end of the vibration motor is connected to a vibration rod that penetrates the inner cavity of the first branch pipe. A support rod connected to the first branch pipe is provided on one side of the vibration rod. Spring plates are formed on the opposite sides of the vibration rod and the support rod. A spring is held between the two spring plates.

[0010] Preferably, the coal chute is connected to the first branch pipe and the second branch pipe respectively through two channels separated by the partition plate.

[0011] Preferably, the flap rotates synchronously with the bushing, and the gap between the flap and the first branch pipe is a coal dropping channel.

[0012] Preferably, the top of the flap is formed with a raised guide plate, and a transmission gap is sandwiched between the two guide plates.

[0013] Preferably, the support rod is a fixed structure, the vibration rod is a vibration structure, and the two are transmitted through a combination structure of the spring plate and the spring.

[0014] Preferably, the drive motor and the vibration motor are arranged from top to bottom along the channel of the first branch pipe.

[0015] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0016] 1. The coal dropping mechanism can temporarily block the branch pipe channel. At this time, the flap is parallel to the branch pipe channel, blocking the coal above the flap. When a large amount of coal needs to be transported, the opening of the coal dropping channel is adjusted, and the accumulated coal falls with a certain impact force, effectively solving the problem of blockage at the bend of the pipeline.

[0017] 2. During the coal falling process, the accumulated coal is prone to blockage. The vibration motor drives the vibrating rod to vibrate, which can cause the spring to deform. With the cooperation of internal and external forces, the deformation helps to prevent the coal from blocking during transportation. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figs. 1-3As shown, the present invention proposes an anti-blocking coal chuting pipe for thermal power plants, including a coal chuting pipe 1, a partition plate 2 installed in the middle of the coal chuting pipe 1, and the ends of the coal chuting pipe 1 are respectively connected to a first branch pipe 3 and a second branch pipe 4.

[0025] The coal dropping mechanism includes a drive motor 51 installed on the first branch pipe 3. A drive shaft 52 is installed at the output end of the drive motor 51. A bushing 53 is fitted on the outer wall of the drive shaft 52. A flap 54 is installed on the bushing 53 to separate the transmission channel of the first branch pipe 3.

[0026] The vibration mechanism includes a vibration motor 61 installed in the first branch pipe 3. The output end of the vibration motor 61 is connected to a vibration rod 62 that passes through the inner cavity of the first branch pipe 3. A support rod 65 connected to the first branch pipe 3 is provided on one side of the vibration rod 62. A spring plate 63 is formed on the opposite side of the vibration rod 62 and the support rod 65. A spring 64 is held between the two spring plates 63.

[0027] It should be noted that: the coal drop pipe 1 is connected to the first branch pipe 3 and the second branch pipe 4 respectively through two channels separated by the partition plate 2, and the coal is transported to the channels combined between the first branch pipe 3 and the second branch pipe 4 and the coal drop pipe 1.

[0028] In this embodiment, the coal dropping mechanism can temporarily block the channel of the first branch pipe 3. At this time, the flap 54 is parallel to the channel of the first branch pipe 3, blocking the coal above the flap 54. When a large amount of coal needs to be transported, the drive shaft 52 at the output end is driven to rotate by the drive motor 51, which drives the flap 54 connected by the bushing 53 to flip downward synchronously. Since the gap between the flap 54 and the inner wall of the first branch pipe 3 is the coal dropping channel, the opening of the coal dropping channel gradually increases, and the accumulated coal falls with a certain impact force, effectively solving the problem of blockage at the bend of the pipeline.

[0029] To facilitate the falling of coal accumulated on the flap 54, the top of the flap 54 is further formed with a raised guide plate 55. A transmission gap is sandwiched between the two guide plates 55. The coal is guided longitudinally by the guide plates 55, which are wider at the top and narrower at the bottom, to prevent coal from accumulating.

[0030] like Fig. 3 As shown, the support rod 65 is a fixed structure, and the vibration rod 62 is a vibration structure. The two are transmitted through a combination structure of the spring plate 63 and the spring 64.

[0031] In one embodiment, during the coal falling process, the accumulated coal is prone to blockage. The vibration motor 61 drives the vibration rod 62 to vibrate. Since the vibration rod 62 and the support rod 65 are transmitted through the combined structure of the spring plate 63 and the spring 64, the spring 64 can be deformed, causing the coal attached to its exterior to fall. At the same time, it will also deform when it is impacted by the coal. With the cooperation of internal and external factors, it assists in the anti-blockage conveying of coal.

[0032] It is understandable that the drive motor 51 and the vibration motor 61 are arranged from top to bottom along the channel of the first branch pipe 3, and the second branch pipe 4 uses the same method for conveying.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
