Abstract
Description
Technical Field
[0001] This utility model relates to a splash-proof baffle for a coal conveying operation device in a thermal power plant, belonging to the field of coal splash prevention technology. Background Technology
[0002] Coal conveying operations are a crucial link in ensuring the stable and efficient operation of thermal power plants. The coal conveying system is responsible for transporting coal from the storage area to the boiler for combustion and power generation. The design, operation, and maintenance of this system directly affect the power plant's production efficiency and safety.
[0003] When coal is transported in a thermal power plant, conveyor belts are used. At transfer points, coal is prone to splashing when it is transferred from one conveyor belt to another. Therefore, baffles are needed to prevent this. However, most baffles are of fixed size and cannot be adjusted according to the size of the transfer point, thus reducing the effectiveness of the baffles. In addition, some transfer points are at an angle, so multiple baffles are required, which not only increases the cost but also reduces the connectivity between the baffles and makes them prone to tipping over, thus reducing the effectiveness of the baffles.
[0004] Therefore, those skilled in the art urgently need to improve the existing baffle structure. Utility Model Content

[0043] In use, the two threaded sleeves 103 rotate inside the connector 102, and are adjusted and fixed according to the conveyor belt transfer point. The baffle 1 is installed on both sides of the conveyor belt. The adjusting screw 104 rotates inside the threaded sleeve 103, and the length of the adjusting screw 104 can be adjusted according to the support angle to support the baffle 1, improve the stability of the baffle 1, and prevent coal from splashing out. Pull the limiting pin 115 out of the limiting hole 108, and then pull the extension plate 106 out of the rectangular groove 114. The limiting pin 115 is embedded in one of the limiting holes 108 under the elastic force of the spring 116, which can limit and fix the extension plate 106. Therefore, the range of the baffle can be adjusted according to the position of the conveyor belt transfer point to better improve the baffle effect.

A threaded sleeve 110 is embedded in the outer surface of the round shaft 117. The support angle can be adjusted by rotating the threaded sleeve 110 on the outer surface of the round shaft 117. The length can be adjusted by adjusting the screw 111. A fixing cone 105 is fixedly installed at one end of both the adjusting screw 111 and the adjusting screw 104. The fixing cone 105 is embedded in the ground to improve stability. The pin 118 is embedded in the round hole 112 under the elastic force of the spring 119 to limit the threaded sleeve 110, so that the threaded sleeve 110 is limited in the mounting groove 109 to prevent it from getting stuck when storing the extension plate 106.

Then, the extension plate 106 is supported by the threaded sleeve 110 and the adjusting screw 111. Two identical anti-splash baffles are symmetrically installed on both sides of the conveyor belt and fixed to the ground on both sides of the conveyor belt using fixing cones. Adjusting screw 104 rotates inside threaded sleeve 103. The length of adjusting screw 104 can be adjusted according to the support angle to support baffle 1, improve the stability of baffle 1, and prevent coal from splashing out. Pull the limiting pin 115 out of the limiting hole 108, and then pull the extension plate 106 out of the rectangular groove 114. Under the elastic force of spring 116, the limiting pin 115 is embedded in one of the limiting holes 108, which can limit and fix the extension plate 106. Therefore, the range of the baffle can be adjusted according to the position of the conveyor belt transfer point to better improve the baffle effect.
[0045] In this embodiment, an installation groove 109 is provided on one side of the extension plate 106. A threaded sleeve 110 is movably embedded inside the installation groove 109. The threaded sleeve 110 can be rotated on the outer surface of the round shaft 117 to adjust the support angle. The adjusting screw 111 can be adjusted to adjust the length. A fixing cone 105 is fixedly installed at one end of both the adjusting screw 111 and the adjusting screw 104. The fixing cone 105 is embedded in the ground to improve stability. The pin 118 is embedded in the round hole 112 under the elastic force of the spring 119 to limit the threaded sleeve 110, so that the threaded sleeve 110 is limited inside the installation groove 109, preventing the extension plate 106 from being stored. When the extension plate 106 is stuck, a through groove 107 is provided on the outer surface of the extension plate 106. The connecting shaft 113 is movably embedded in the through groove 107, which can limit the extension plate 106 and also allow the extension plate 106 to rotate to adjust the blocking angle. The adjustment is made according to the angle of the transfer point. The conveyor belt used in coal transportation has a transfer point at the connection between the conveyor belts. The transfer point is usually 90 degrees or greater. The extension plate 106 can be adjusted by rotating on the outer surface of the connecting shaft 113. Then, the extension plate 106 is supported by the threaded sleeve 110 and the adjusting screw 111 to better block the coal and prevent it from splashing out.
