Description

Technical Field

[0001] This utility model relates to the field of coal powder production and transmission technology, specifically a high-efficiency production and transmission line. Background Technology

[0002] With the continuous advancement of global industrialization, the demand for energy in numerous industrial sectors is showing a sustained upward trend. As one of the main fuels for thermal power generation, the stable and abundant supply of pulverized coal is a key factor in ensuring the continuous operation of power generation. Against the backdrop of global efforts to optimize the energy structure and seek clean and efficient energy utilization, coal, although facing competition from renewable energy sources, remains one of the important basic energy sources. Processing coal into pulverized coal allows for better and more refined utilization of coal resources. Compared to directly burning raw coal, this improves combustion efficiency and reduces pollutant emissions, enabling it to continue playing an important and more environmentally friendly role in the energy structure transformation process.

[0003] Traditional coal powder transport first involves screening the coal powder raw material using independent screening equipment in a specific screening area, separating the coal powder into qualified products and waste materials according to particle size and other requirements. Then, the qualified coal powder is transported to the next production stage by manual handling or with the help of other conveyor equipment, depending on the specific site layout. Screening and conveying are two independent steps. After screening, additional time and manpower are required to transfer the coal powder to the conveyor belt. This process involves material accumulation and waiting for loading, which can easily lead to untimely connection and interruption of the entire production process. This makes it impossible to achieve continuous and efficient production, thus affecting the overall production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency production transmission line that solves the problem of requiring separate screening of pulverized coal raw materials during production and transmission.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency production conveyor line, comprising a first conveyor belt mechanism and a second conveyor belt mechanism. The second conveyor belt mechanism is disposed below the first conveyor belt mechanism. Slide plates are fixedly connected to the front and rear sides of the bottom of the first conveyor belt mechanism. A slider is slidably installed inside the slide plate. A movable plate is fixedly connected to the bottom of the slider. A screening screen plate is fixedly connected between the two movable plates. The second conveyor belt mechanism includes a conveyor frame. A drive motor is fixedly connected to the rear side of the conveyor frame via a connector. The output end of the drive motor... A rotating rod is fixedly connected via a coupling. One end of the rotating rod passes through the conveyor frame and extends into the interior of the conveyor frame. A drive roller is fixedly connected to the end of the rotating rod extending into the interior of the conveyor frame. Several driven rollers are rotatably connected between the inner walls of the conveyor frame. The drive roller and the several driven rollers are connected by a conveyor belt. A rotating shaft is rotatably connected to the front side of the conveyor frame via a bearing. One end of the rotating shaft passes through the conveyor frame and extends into the interior of the conveyor frame. The end of the rotating shaft extending into the interior of the conveyor frame is fixedly connected to the drive roller. A cam that cooperates with a moving plate is fixedly connected to the front end of the rotating shaft.

[0006] Preferably, a spring is fixedly connected between the side wall of the slide plate and the slider.

[0007] Preferably, the front and rear sides of the top of the first conveyor belt mechanism are fixedly connected with baffles that cooperate with the screening screen.

[0008] Preferably, vertical rods are fixedly connected to the front and rear sides of the top of the screening screen plate, and the top ends of the two vertical rods are fixedly connected to a first brush plate that cooperates with the first conveyor belt mechanism.

[0009] Preferably, a second brush plate for use with the conveyor belt is fixedly connected to the bottom between the two moving plates.

[0010] Beneficial effects

[0011] This invention provides a high-efficiency production transmission line. It has the following beneficial effects:

[0012] This invention, through the cooperation of a first conveyor belt mechanism, a second conveyor belt mechanism, and a screening mechanism, enables the screening of unscreened coal powder as it passes through the screening screen plate under gravity. The cooperation between the moving plate and the cam allows the screening screen plate to move repeatedly, effectively preventing coal powder from clumping or clogging the screen holes, greatly improving screening efficiency. It ensures that coal powder meeting the particle size requirements falls onto the second conveyor belt mechanism. The entire screening and conveying process achieves a certain degree of automation. The first conveyor belt mechanism continuously supplies unscreened coal powder, which, after being screened by the screen plate, falls directly into the second conveyor belt mechanism below. The conveyor belt mechanism then proceeds to the next stage of transport, while substandard coal powder and waste slide into the collection pile. The cam drives the screen plate to move repeatedly, which also accelerates the screening speed, thereby significantly improving the production efficiency of the entire coal powder production line and meeting the needs of large-scale production. The power of the second conveyor belt mechanism is converted into the screening power of the screen plate, eliminating the need for an additional complex power source, reducing equipment costs and energy consumption, and improving the reliability and economy of the equipment. At the same time, through the cooperation between the first brush plate and the second brush plate, the conveyor belts of the first and second conveyor belt mechanisms can be cleaned simultaneously during the coal powder transport process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency production transmission line, including a first transmission belt mechanism 1 and a second transmission belt mechanism 2. The second transmission belt mechanism 2 is located below the first transmission belt mechanism 1. Slide plates 3 are fixedly connected to the front and rear sides of the bottom of the first transmission belt mechanism 1. A slider 4 is slidably installed inside the slide plate 3. A movable plate 5 is fixedly connected to the bottom of the slider 4. A screening screen plate 6 is fixedly connected between the two movable plates 5. The second transmission belt mechanism 2 includes a conveyor frame 201. A drive motor 202 is fixedly connected to the rear side of the conveyor frame 201 via a connector. A rotating rod 203 is fixedly connected to the output end of the drive motor 202 via a coupling. One end of the rotating rod 203 passes through the conveyor frame 201 and extends into the interior of the conveyor frame 201. The end of the rotating rod 203 extending into the interior of the conveyor frame 201 is fixedly connected to the drive roller 204. Several driven rollers 205 are rotatably connected between the inner walls of the conveyor frame 201. The drive roller 204 and several driven rollers 205 are connected by a conveyor belt 206. The front side of the conveyor frame 201 is rotatably connected to the rotating shaft 7 through a bearing. One end of the rotating shaft 7 passes through the conveyor frame 201 and extends into the interior of the conveyor frame 201. The end of the rotating shaft 7 extending into the interior of the conveyor frame 201 is fixedly connected to the drive roller 204. The front end of the rotating shaft 7 is fixedly connected to a cam 8 that cooperates with the moving plate 5.

[0021] A spring 9 is fixedly connected between the side wall of the slide plate 3 and the slider 4.

[0022] Both the front and rear sides of the top of the first conveyor belt mechanism 1 are fixedly connected to baffle plates 10 that cooperate with the screening screen plate 6. When the coal powder material moves forward under the drive of the first conveyor belt mechanism 1 and comes into contact with the baffle plate 10, the baffle plate 10 can gather the coal powder material to ensure that the coal powder material accurately contacts the screening screen plate 6.

[0023] Vertical rods 13 are fixedly connected to the front and rear sides of the top of the screening screen plate 6, and the top ends of the two vertical rods 13 are fixedly connected to the first brush plate 11, which is used in conjunction with the first conveyor belt mechanism 1.

[0024] A second brush plate 12, which is used in conjunction with the conveyor belt 206, is fixedly connected between the bottoms of the two movable plates 5.

[0025] During operation, the pulverized coal is conveyed through the first conveyor belt mechanism 1. Under the action of gravity, the pulverized coal passes through the screening screen plate 6, which can achieve screening. The drive motor 202 drives the rotating shaft 7 to rotate through the rotating rod 203. The rotation of the rotating shaft 7 drives the cam 8 to rotate. The rotation of the cam 8 abuts against the moving plate 5, and the cam 8 drives the moving plate 5 to move. At the same time, as the cam 8 rotates, the elastic force of the spring 9 can drive the moving plate 5 to return to the initial position, so that the rotation of the cam 8 drives the screening screen plate 6 to reciprocate through the moving plate 5. The qualified pulverized coal falls to the second conveyor belt mechanism 2 and is conveyed to the designated area by the second conveyor belt mechanism 2. The unqualified pulverized coal and large impurities slide into the collection pile.
