The construction of an intelligent power plant aims to achieve safe, efficient, green, and low-carbon power generation. Its characteristics include that the production process can be autonomously optimized, and relevant systems can collect, analyze, judge, and plan their own behaviors, and intelligently online dynamically optimize the configuration of equipment and its parameters;

[0003] Among them, the coal feeding device for an intelligent power plant is a device used to transport coal from the storage place to the combustion equipment, and is mainly used in occasions such as coal-fired industrial boilers and heating furnaces. This device usually includes multiple functional modules such as conveying, pulverizing, and feeding to ensure that coal can be continuously and evenly fed into the combustion equipment to improve combustion efficiency and safety.

[0004] The coal feeding device is arranged with an open structure during the conveying process. During this conveying process, a certain degree of dust particles will float around, which will affect the operators around the equipment. At the same time, the dust will also settle on the surface of the surrounding equipment, increasing the difficulty of equipment maintenance and making the operation time-consuming and laborious.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a coal feeding device for an intelligent power plant is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a coal feeding device for an intelligent power plant to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A coal feeding device for an intelligent power plant includes a dust removal component and a device frame. The device frame is installed at the inner bottom end of the dust removal component, and a belt conveyor is installed on the top of the device frame. One end of the belt conveyor is provided with a pretreatment device, and a feed hopper is installed on the top of the pretreatment device. The dust removal component includes a combined bin, an exhaust pipe rack, dust removal bags, and a turbine fan. The exhaust pipe rack is installed on the top of the combined bin, the dust removal bags are arranged in the middle of the exhaust pipe rack, and the turbine fan is installed on the top of the combined bin.

[0008] Furthermore, the dust removal component further includes a docking block and a docking pile. The docking block is installed on one side of the inner top end of the combined bin, and the docking pile is installed on the side of the inner top end of the combined bin far from the docking block.

[0009] Furthermore, the dust removal cloth bag is internally connected to the combined bin, and the exhaust duct rack is fixedly connected to the combined bin.

[0010] Furthermore, a jack structure matching the surface structure of the docking pile is provided in the middle of the docking block, and both the docking pile and the docking block are welded to the combined bin.

[0011] Furthermore, the pretreatment device includes a treatment bin, a feed inlet, and a discharge outlet. The feed inlet is provided at the top of the treatment bin, and the discharge outlet is provided on the side elevation of the treatment bin.

[0012] Furthermore, the feed hopper is installed at the top of the feed inlet through a flange structure, the discharge outlet is provided on the side of the treatment bin close to the dust removal assembly, and one end of the belt conveyor is arranged inside the treatment bin.

[0013] Furthermore, the pretreatment device further includes a first crushing roller, a second crushing roller, and a control motor. The first crushing roller is installed at the upper end inside the treatment bin, the second crushing roller is installed on one side of the first crushing roller, and control motors are installed at both ends of the first crushing roller and the second crushing roller.

[0014] Furthermore, the first crushing roller and the second crushing roller have the same structure and are arranged parallel to each other, and the power output end of the control motor is connected to the first crushing roller and the second crushing roller through a coupling.

[0015] The utility model provides a coal feeding device for a smart power plant, which has the following beneficial effects:

[0016] 1. In the utility model, a pretreatment device is provided at one end of the belt conveyor. When the coal to be transported is put into the treatment bin from the feed hopper, driven by the control motors on both sides, the connected first crushing roller and second crushing roller will rotate axially in the horizontal direction, so as to quickly crush the coal falling on the surfaces of the first crushing roller and the second crushing roller by the rolling extrusion of the structure, and then fall onto the surface of the belt conveyor directly below and be transported. By using the above structure, the coal can be pre-processed as much as possible to ensure full combustion and heat generation during subsequent use, and at the same time, it can also avoid the problem of debris splashing during crushing, and reduce the problem of the coal rolling during the transportation process of the belt conveyor due to its large volume.

[0017] 2. In the present utility model, a dust removal assembly is provided around the belt conveyor. The entire belt conveyor is installed inside the treatment bin by means of a device rack. When dust is generated during the transportation of the coal being crushed by the belt conveyor, under the operation of the turbine fan, the dust inside the combined bin will be quickly extracted and enter the inside of the dust removal cloth bag, thereby realizing filtration and collection. By using the above structure, it can effectively ensure that the dust raised during the transportation of the coal will not fly around, thus effectively protecting the working environment and providing health protection for the operators. In addition, since docking blocks and docking piles are respectively arranged at both ends of the top inside the combined bin, due to the structural insertability between the two, several dust removal assemblies can be spliced and combined structurally by using the combination of the two structures, thereby expanding the structure. By using the above structure, it can effectively ensure the convenience and flexibility of the use of the device structure, and at the same time prevent external equipment from causing unnecessary impacts on the coal during transportation to ensure the effectiveness of the feeding.

The dust removal bags 103 communicate with the inside of the combined bin 101, and the exhaust pipe rack 102 is fixedly connected to the combined bin 101. The middle of the docking block 105 is provided with an insertion hole structure that matches the surface structure of the docking pile 106, and both the docking pile 106 and the docking block 105 are welded to the combined bin 101. When the pulverized coal generates dust during the transportation of the belt conveyor 3, under the operation of the turbo fan 104, the dust inside the combined bin 101 will be quickly extracted and enter the inside of the dust removal bags 103, so as to achieve filtration and collection. In addition, since the docking block 105 and the docking pile 106 are respectively arranged at both ends of the inner top of the combined bin 101, by using the structural insertability between the two, several dust removal components 1 can be spliced and combined in structure by using the combination of the two structures.

[0025] As Figures 1 to 4As shown in the figure, the pretreatment device 4 includes a processing bin 401, a feed inlet 402, and a discharge outlet 403.
