Moreover, there is a possibility of human factors interfering with or changing the authenticity of coal samples. At the same time, due to limited management means, the real-time working status and data of incoming coal during the sampling, sample preparation, and analysis processes cannot be analyzed and fed back in a timely manner, affecting real-time performance and failing to meet the requirements of real-time supervision and precise management. Therefore, in order to reduce enterprise costs and improve fuel management levels, the development of fuel management information systems has been increased, the fuel resource allocation has been optimized, and the sampling and full-automatic unattended operation of incoming coal sampling and sample preparation have been realized, thereby reducing labor costs, improving work efficiency, and achieving full-process real-time management, real-time analysis, and closed-loop control through seamless connection with the intelligent control system;

To build an integrated fuel intelligent control system on the input side of flue gas water extraction in a thermal power plant, generally, after the fuel is transported, it needs to be unloaded and transported, and then the fuel is transmitted. During the transmission, manual sampling by staff is required for preservation, which is time-consuming and laborious. At the same time, during the transmission process, due to the fast blanking speed of the transport vehicle at the blanking stage, the conveying equipment cannot convey it in time, resulting in blockage. Summary of the Utility Model

[0012] Beneficial effects

[0013] The present utility model provides a fuel control system. Compared with the prior art, it has the following beneficial effects:

[0014] 1. In the present utility model, through the provided sampling mechanism, when the fuel is being transported at a constant speed, by opening the electric gate valve, the fuel can fall into the sampling pipe. The remaining weight is detected by the rotameter, and then when the set value is reached, the electric gate valve is closed.

[0015] 2. In the present utility model, through the provided blanking port and conveying mechanism, etc., when the transport vehicle is unloading, the fuel is directly poured into the blanking port. At this time, the blanking port is set as a wide mouth, so the fuel will fall along the lower end of the blanking port into one end of the conveying pipe and be transported away at a constant speed. The remaining materials will slowly fall along with the limitation of the blocking plate. Through the provided conveying mechanism, the screw feeder can rotate to feed at a constant speed, avoiding the situation of blockage at the blanking end, effectively improving the efficiency of fuel control and the automation efficiency.

[0016] 3. In the present utility model, through the arranged cleaning mechanism, after a single sampling is completed, the electric sealing door opens, and then the electric spray head starts to spray water to clean the inside of the sampling pipe, flushing away the fuel debris inside the sampling pipe. Subsequently, the hot air blower is started to dry the inside of the sampling pipe to complete the cleaning, which can effectively prevent the residue from the previous sampling from mixing into the next sampling sample and affecting the detection accuracy, and effectively improve the accuracy of sampling.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Please refer to Figures 1-4 , the present utility model provides two technical solutions, specifically including the following embodiments:

[0025] Embodiment 1:

[0026] A fuel control system includes a delivery pipe 1. Inside the delivery pipe 1, there is a delivery mechanism 6 for feeding the material at a uniform speed to prevent blockage. One end of the delivery pipe 1 is fixedly connected to a feeding port 2 for receiving the material. The other end of the delivery pipe 1 penetrates and is fixedly connected to a discharging pipe 5 for discharging the material. A sampling mechanism 3 is arranged on the lower side of the middle part of the delivery pipe 1 for automatic sampling. The sampling mechanism 3 includes a sampling pipe 301, an electric gate valve 302, a rotameter 303, a temperature sensor 304, and a humidity sensor 305. Inside the upper end of the sampling pipe 301, there is fixedly connected an electric gate valve 302 for blocking the falling of the fuel. In the middle of the sampling pipe 301, there is fixedly connected a rotameter 303. The rotameter 303 uses a rotor valve to control the flow of the material and can be equipped with a sensor for weight measurement and automatically closes after reaching the set value. Inside the lower end of the sampling pipe 301, there is a sensing component. The sensing component is composed of multiple temperature sensors 304 and humidity sensors 305 and is fixedly connected to the lower end of the sampling pipe 301. The temperature sensor 304 is a GWD150 mining temperature sensor, and the humidity sensor 305 is a GWSD100 / 100 mining intrinsically safe temperature and humidity sensor. The delivery mechanism 6 includes a rotating motor 601, a transmission rod 602, and a spiral feeder 603. The rotating motor 601 is fixedly connected to the end of the delivery pipe 1 away from the feeding port 2. The output end of the rotating motor 601 penetrates and is arranged in the middle of the delivery pipe 1 and is fixedly connected to a transmission rod 602. The outside of the transmission rod 602 is wound and fixedly connected with a spiral feeder 603. The rotation of the transmission rod 602 drives the rotation of the spiral feeder 603 to feed the material. Inside the feeding port 2, there is an inclined and fixedly connected blocking plate 7 for limiting the fuel;

[0027] During operation, when the transport vehicle unloads the fuel, it directly pours the fuel into the feeding port 2. At this time, the feeding port 2 is set with a wide opening, so the fuel will fall along the lower end of the feeding port 2 into one end of the delivery pipe 1 and be transported away at a uniform speed. At this time, the rotating motor 601 is started to drive the spiral feeder 603 to rotate, and the material is transported into one end of the delivery pipe 1 and falls through the discharging pipe 5 to complete the transportation. The remaining material will slowly fall along with the limitation of the blocking plate 7. When the fuel is being transported at a uniform speed, by opening the electric gate valve 302, the fuel can fall into the sampling pipe 301. The weight of the fuel left is detected by the rotameter 303, and then the electric gate valve 302 is closed when the set value is reached. Subsequently, the sampling pipe 301 transmits the sampled sample to the corresponding equipment for monitoring. At the same time, the temperature sensor 304 and the humidity sensor 305 can record the temperature and humidity of the sample in the first time to prevent the situation that the detection is inaccurate due to the change of temperature and humidity during the transfer of the sample piece, effectively improving the sampling efficiency and automation.

The inner side of the cleaning box 401 is fixedly connected to the outer side of the sampling tube 301, and an electric sealing door 402 is arranged on the adjacent side of the sampling tube 301 and the cleaning box 401. The electric sealing door 402 is opened to allow the electric nozzle 403 and the hot air blower 405 to clean the inside of the sampling tube 301. A plurality of hot air blowers 405 are fixedly connected to the upper array in the cleaning box 401, and the hot air blower 405 dries the inside of the sampling tube 301. A plurality of electric nozzles 403 are arranged in an array at the lower end of the cleaning box 401. A water pipe 404 is fixedly connected between the electric nozzles 403, and one end of the water pipe 404 is fixedly connected to the external water pipe. The electric nozzle 403 sprays water to clean the inside of the sampling tube 301.

[0030] After a single sampling is completed, the electric sealing door 402 opens, and then the water pipe 404 draws clean water into each electric nozzle 403. The electric nozzle 403 starts to spray water to clean the inside of the sampling tube 301, flushing away the fuel debris inside the sampling tube 301. Then the hot air blower 405 starts to dry the inside of the sampling tube 301 to complete the cleaning.
