Description

Technical Field

[0001] This utility model relates to the field of fuel transportation technology in thermal power plants, and specifically to a transmission device for fuel use in thermal power plants. Background Technology

[0002] Thermal power plant fuel generally refers to the fuel required for electricity production in thermal power plants. The fuels used in thermal power plants are broadly classified into solid fuels, liquid fuels, and gaseous fuels. Solid fuel is mainly coal, which consists of carbon, ash, moisture, and volatile matter. Currently, when using solid fuels and coal as fuel, thermal power plants frequently need to use trolleys and other tools to transport and move the coal. This process imposes a significant workload on workers and reduces the efficiency of coal transportation.

[0003] To address the fuel transport issues in thermal power plants mentioned above, existing technologies employ a method of conveying fuel via spiral guide vanes and conveyor belts. However, this method still suffers from the problem of not crushing and screening the fuel, leading to transport blockages due to the excessive size of the fuel. Utility Model Content

[0004] The purpose of this invention is to provide a transmission device for fuel use in thermal power plants, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A transmission device for fuel use in thermal power plants includes a crushing mechanism, a dust collection mechanism on one side of the crushing mechanism, and a transmission component installed at one end of the dust collection mechanism.

[0007] The crushing mechanism includes a crushing box and an electric telescopic column. A feed pipe is fixedly connected to the top of the crushing box. A material distribution frame and a discharge frame are fixedly connected to both sides of the crushing box, respectively. A first servo motor is fixedly connected to one side of the crushing box. A toothed crushing roller is fixedly connected to the output end of the first servo motor. The first servo motor can switch between forward and reverse rotation to realize coarse crushing and fine crushing in two stages. A screen is fixedly connected inside the crushing box. The screen is inclined. A guide plate is fixedly connected inside the crushing box.

[0008] The dust collection mechanism includes a dust collection box, a movable groove on one side of the dust collection box, and a limiting frame fixedly connected to both sides inside the dust collection box. A stop door is slidably connected inside the limiting frame and moves inside the limiting frame.

[0009] A further improvement of this utility model is that: a second vibration motor is installed inside the guide plate, a first vibration motor is installed on one side of the crushing box, the electric telescopic column is fixedly connected to one side of the crushing box, a cleaning brush is fixedly connected to the telescopic end of the electric telescopic column, the cleaning brush moves on the surface of the screen, and the guide plate drives the fuel to be discharged through the discharge frame by the vibration of the second vibration motor.

[0010] A further improvement of this utility model is that a dust collection box is installed at one end of the dust pump, and the dust collection box is threadedly connected to one side of the collection box. When the dust pump is started, the dust pump drives the dust to form a negative pressure inside the collection box, and then the dust on the fuel is passed through the filter screen.

[0011] A further improvement of this utility model is that a ventilation pipe is installed on the surface of the dust pump, and the ventilation pipe is used for ventilation.

[0012] A further improvement of this utility model is that: a sealing plate is fixedly connected to one end of the baffle, a cylinder is provided at one end of the sealing plate, the telescopic end of the cylinder is fixedly connected to one side of the sealing plate, a discharge pipe is fixedly connected to the bottom of the dust collection box, and a discharge valve is installed on the surface of the discharge pipe. When the cylinder is activated, the telescopic end of the cylinder drives the baffle at one end of the sealing plate to move within the limiting frame, and the baffle seals the collection box.

[0013] A further improvement of this utility model is that: the transmission component includes a transmission pipe, which is fixedly connected to one end of the discharge pipe, a second servo motor is fixedly connected to one side of the transmission pipe, a conveying screw shaft is fixedly connected to the output end of the second servo motor, and a discharge pipe is fixedly connected to one end of the transmission pipe. The second servo motor drives the conveying screw shaft to rotate, and the conveying screw shaft conveys the fuel out.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a transmission device for fuel use in thermal power plants. A first servo motor is activated, driving a toothed crushing roller to rotate. The toothed crushing roller crushes the fuel, and the crushed fuel falls onto a screen with a mesh size of 5-15mm. A first vibrating motor drives the screen to vibrate, screening the fuel. Qualified fuel passes through the screen, while unqualified fuel is discharged through a distribution frame due to the screen's tilt angle. When the screen becomes clogged, an electric telescopic column is activated, driving a cleaning brush to remove residual fuel from the screen, making fuel screening more precise and effective.

[0016] This invention provides a transmission device for fuel use in thermal power plants. When the discharge valve is opened, the discharge pipe transmits fuel into the transmission pipe. At this time, a second servo motor drives the conveying screw shaft to rotate, and the conveying screw shaft conveys the fuel out. By driving the conveying screw shaft to rotate, the second servo motor can precisely adjust the material conveying speed and flow rate to adapt to different working conditions. The cooperation between the screw conveying shaft and the transmission pipe can reduce the risk of material blockage. At the same time, the closed-loop control characteristics of the servo motor enhance the stability of the transmission process, thereby achieving the effect of reducing fuel residue or leakage and improving conveying efficiency during transmission.
