[0002] In scenarios such as thermal power plants that require coal transportation, a three-way baffle is usually adopted inside the material distribution device to achieve the conduction and switching of different operation paths. By blocking different discharge ports with the baffle, the control of the coal transportation path is realized. However, during the coal transportation process, dust accumulation or dust blocks will form at the discharge port, affecting the use of the three-way baffle and even causing the three-way baffle to be blocked. Therefore, it is necessary to frequently remove the dust blocks to ensure the stable operation of the equipment.

[0003] In the prior art, the dust block removal work is usually carried out manually. During the cleaning process, the coal conveying system needs to be shut down for a long time, which not only affects the overall production efficiency of the equipment, but also poses a hidden danger of damage to the three-way baffle due to the influence of the operation personnel's level.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] As Figure 1 and Figure 2 shown, the present utility model provides an anti-blocking three-way baffle structure for a coal conveying pipe, including a housing 10, an adjusting mechanism 100, and a baffle 20; a feeding port 11 is provided at the top inside the housing 10, and coal enters the cavity of the housing 10 through the feeding port 11, and the coal in the cavity is conveyed to the corresponding conveyor belt through the first discharge port 12 or the second discharge port 13 located at the bottom of the cavity;

[0025] The adjusting mechanism 100 is connected to the baffle 20 located inside the cavity and drives the baffle 20 to move inside the cavity, and the baffle 20 fits against the first discharge port 12 or the second discharge port 13 during the movement.

[0026] The structure includes a housing 10, an adjusting mechanism 100 and a baffle 20; a feeding port 11 is provided at the top inside the housing 10, and coal enters the cavity of the housing 10 through the feeding port 11, and the coal in the cavity is conveyed to the corresponding conveyor belt through the first discharge port 12 or the second discharge port 13 at the bottom of the cavity; the adjusting mechanism 100 is connected to the baffle 20 inside the cavity. When there are dust blocks at the first discharge port 12, the baffle 20 moves from the end facing the second discharge port 13 towards the first discharge port 12. Since the baffle 20 fits against the first discharge port 12, the dust blocks are shoveled onto the baffle 20. As the baffle 20 moves to a certain angle, the accumulated dust is discharged from the second discharge port 13. When there is accumulated dust at the second discharge port 13, the principle is the same as above and will not be elaborated here. Thus, the entire process of accumulated dust can be achieved by controlling the movement of the baffle 20, alleviating the technical problems in the prior art where manual operation is used to remove dust blocks, resulting in low work efficiency. At the same time, due to the influence of the level of operating personnel, there is a hidden danger of damage to the three-way baffle 20, and the work efficiency is improved.

[0027] Further, the adjusting mechanism 100 includes a power member 110, a disc 120, a transmission assembly 130 and a telescopic rod 140. The disc 120 is rotatably connected to the inner wall of the cavity, and the baffle 20 is disposed at one end of the disc 120. Under the rotation of the disc 120, the baffle 20 moves between the first discharge port 12 and the second discharge port 13;

[0028] One end of the telescopic rod 140 is connected to the disc 120 through the transmission assembly 130, and the other end is connected to the power member 110, and the power member 110 drives the telescopic rod to expand and contract.

[0029] Further, the transmission assembly 130 includes a first transmission rod 131, a second transmission rod 132 and a bearing seat 133. The second transmission rod 132 is disposed inside the bearing seat 133; and one end of the second transmission rod 132 penetrates through the housing 10 and is connected to the disc 120, and the other end is connected to the telescopic rod 140 through the first transmission rod 131.

[0030] In this embodiment, the power member 110 can adopt power elements such as a hydraulic pump and a motor, and the telescopic rod 140 can be matched with a hydraulic rod, a gear mechanism, etc. to realize the telescopic movement of the telescopic rod 140;

[0031] When there are dust blocks at the first discharge port 12, the baffle 20 is located at the end of the disc 120 facing the second discharge port 13. When the telescopic rod 140 extends, the telescopic rod 140 drives the first transfer rod 131 to swing. Since the first transfer rod 131 is connected to the disc 120 through the second transfer rod 132, under the support of the bearing in the bearing seat 133, the first transfer rod 131 and the disc 120 rotate synchronously. The baffle 20 provided at one end of the disc 120 gradually moves from the second discharge port 13 towards the first discharge port 12, and gradually shovels the dust blocks at the first discharge port 12 above the baffle 20. As the baffle 20 continues to move, the angle between the baffle 20 and the horizontal direction also gradually increases. When it reaches a certain angle, the dust blocks are output along the baffle 20 towards the second discharge port 13, achieving the effect of dust removal.

[0032] When there are dust blocks at the second discharge port 13, the baffle 20 is located at the end of the disc 120 facing the first discharge port 12. The power component 110 drives the telescopic rod 140 to retract, and drives the baffle 20 to gradually move towards the second discharge port 13 through the first transfer assembly 130, and gradually shovels the dust blocks at the second discharge port 13 above the baffle 20. As the baffle 20 continues to move, the angle between the baffle 20 and the horizontal direction also gradually increases. When it reaches a certain angle, the dust blocks are output along the baffle 20 towards the first discharge port 12.

[0033] It should be noted that the angle at which the baffle 20 rotates with the disc 120 is less than 60°.

[0034] Furthermore, both ends of the baffle 20 are wedge-shaped structures.

[0035] The setting of the wedge-shaped structure facilitates the transfer of dust blocks onto the baffle 20 during the movement of the baffle 20.

[0036] Furthermore, the adjusting mechanism 100 is detachably connected to the housing 10.

[0037] The force component, the disc 120, the first transfer rod 131, the second transfer rod 132, the bearing seat 133, and the telescopic rod 140 in the adjusting mechanism 100 can all be detachably connected to the housing 10 by means of threaded connection, plug-in connection, etc., which is convenient for installation and later maintenance.

[0038] Furthermore, a bearing seat 133 is provided at the lower part of the housing 10.

[0039] In the prior art, the bearing seat 133 is on the two side panels of the housing 10, and it is easy for powder to enter the inner side of the bearing and the bearing gets stuck and cannot work. While in this embodiment, the bearing seat 133 is supported by a bearing seat 133 support base, which independently supports the bearing seat 133 to prevent dust from entering.

[0040] In a second aspect, the present embodiment further provides a material distributing device, which includes the anti-blocking three-way baffle 20 structure for the coal conveying pipe described above.

[0041] The principle of the material distributing device has been described above and will not be elaborated here.

[0042] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
