Description

Technical Field

[0001] This utility model relates to the field of boiler fuel feeding technology, and in particular to an automatic boiler fuel feeding device. Background Technology

[0002] Boiler fuel refers to the fuel used in various boilers. There are three categories: solid, liquid, and gaseous boiler fuels. Solid boiler fuel usually refers to coal, which is the main fuel for power plant boilers in my country. To ensure combustion efficiency, coal usually needs to be crushed.

[0003] A search revealed that Chinese Patent CN202123172004.2 discloses a boiler fuel feeding device. Through the cooperation of the boiler body, bottom box, ash chamber, fire chamber, vertical plate, chute, roller, lifting platform, guide wheel, cylinder, inclined block, discharge hopper, support plate, boiler feeding pipe, first motor, rotating rod, spiral conveyor blade, discharge pipe, feeding port, crushing box, second motor, rotating shaft, crushing blade, feeding port and unloading pipe, the boiler fuel feeding device can crush the fuel through the crushing mechanism to improve the fuel combustion efficiency.

[0004] The above-mentioned technical solution has the following drawbacks: although such a feeding device can crush boiler fuel through crushing blades to improve combustion efficiency, it cannot screen the processed boiler fuel in actual use, resulting in incompletely crushed boiler fuel being fed into the boiler. Therefore, an automatic boiler fuel feeding device is proposed, which can screen the crushed boiler fuel and screen out the uncrushed boiler fuel for secondary processing. A dust collection hood is installed at the crushing position to collect and treat the dust generated during coal fuel crushing, which can prevent it from affecting the working environment and improve work efficiency.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides an automatic boiler fuel feeding device that solves the problems mentioned in the background. It can screen the crushed boiler fuel and screen out the uncrushed boiler fuel for secondary processing. A dust collection hood is set at the crushing position to collect the dust generated during coal fuel crushing, which can prevent it from affecting the working environment and improve work efficiency.

[0008] The present invention provides the following solution to the above-mentioned technical problems: An automatic boiler fuel feeding device includes a fuel conveying pipe, a fuel processing box, a pulse bag filter, and a collection cylinder. The boiler fuel processing box is equipped with a discharge hopper, which is connected to the fuel conveying pipe. A rotating motor is fixedly installed on the fuel conveying pipe, and a feeding spiral blade is installed on the drive end of the rotating motor. The fuel conveying pipe is fixedly connected to a boiler feeding pipe. The fuel processing box is fixedly connected to a feeding hopper, and an equipment box is installed on the feeding hopper. A drive motor is fixedly installed on the equipment box. A crushing roller is rotatably connected to the fuel processing box, and the drive end of the drive motor is connected to the crushing roller. A mesh belt conveyor is provided in the fuel processing box. The fuel processing box and the collection cylinder are connected, and a sealing cover is threaded onto the collection cylinder. The pulse bag filter is fixedly connected to a connecting pipe and an air pump, and a dust collection hopper is fixedly connected to the connecting pipe.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0018] 2. The processed coal can be conveyed to the mesh belt conveyor through the guide bucket. The fully crushed coal can pass through the mesh of the mesh belt conveyor and then be conveyed to the fuel conveying pipe through the collection cylinder. The incompletely crushed coal can be conveyed to the collection cylinder by the mesh belt conveyor for collection so that it can be taken out and reused later.

[0019] 3. Start the rotating motor to rotate the feeding screw blade, which will drive the crushed coal blocks to be transported in the fuel conveying pipe and discharged to the boiler through the boiler feeding pipe for feeding.

[0020] 4. Start the air pump to extract the coal ash from the fuel handling box through the dust collection hopper at the connecting pipe. Fine coal ash can pass through the protective net and be collected into the pulse bag dust collector through the dust collection hopper and connecting pipe.

[0021] 5. This automatic boiler fuel feeding device can automatically crush, screen and convey the coal lumps, thus ensuring feeding efficiency while ensuring complete combustion of boiler fuel.

[0022] 6. This automatic boiler fuel feeding device can screen the crushed boiler fuel and screen out the uncrushed boiler fuel for secondary processing. A dust collection hood is installed at the crushing position to collect the dust generated during coal crushing, which can prevent it from affecting the working environment and improve work efficiency.
