Description

Technical Field

[0001] The utility model relates to the technical field of boiler charging, in particular to an anti-blocking boiler charging device. Background Art

[0002] A boiler is a device that uses the heat or other energy released by fuel combustion to heat the working fluid to certain parameters. Boilers are widely used in various industries such as food, clothing, medical care, pharmaceuticals, chemicals, and building materials processing. When the boiler is running, it is often necessary to use a boiler charging device to add fuel to the boiler.

[0003] The publication number authorized by China is CN213630495U, and it is a patent for a charging device for a cleaning boiler. The device includes a base, an upper surface of the base is fixedly connected to a feed bin, a through slot is provided on the top of the feed bin, a cover plate is arranged above the through slot, a mounting frame is fixedly connected to the upper surface of the feed bin, a slide slot is provided on the mounting frame, the inner cavity of the slide slot is slidably engaged with the cover plate, and both sides of the upper surface of the mounting frame are fixedly connected to fixed blocks, a slide rod is slidably inserted and connected to the middle of the fixed block, a connecting block is fixedly connected to the bottom end of the slide rod, and a spring is fixedly connected to the upper surface of the connecting block, and the spring is movably sleeved with the slide rod. The utility model utilizes a setting method in which the fixed block, the slide rod and the spring are matched. When the slide rod is pressed, the spring is stretched, and the connecting block squeezes the cover plate downward. When the squeezing of the connecting block is released, the spring contracts, so that the slide rod returns to its initial state, which is convenient for ensuring the sealing of the cover plate to the through slot at the top of the feed bin, and convenient for installing and removing the cover plate.

[0004] Although the above device can facilitate the installation and removal of the cover plate, there are still some problems when using the device:

[0005] 1. The device does not have a blockage detection and unblocking mechanism, and cannot prevent the device from being blocked. Therefore, the bottom of the feed hopper with a closed-end design is easily blocked due to the extrusion and static friction of the material.

[0006] 2. The device does not have a flow monitoring mechanism. When the user uses the device to add material, it is difficult to grasp the amount of material added, so it is easy to add too much or too little material.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing boiler charging device. Utility Model Content

Zero processing, when there is material in the feeding hopper 1, the pressure sensor 9 will output an electrical signal to the industrial computer 10 due to the increase in pressure. Therefore, when the pressure sensor 9 outputs an electrical signal, the industrial computer 10 will determine that there is material in the feeding hopper 1. When the pressure sensor 9 outputs an electrical signal and the flow tube 5 monitors that the material flow rate is zero or the flow rate is significantly lower, the industrial computer 10 will determine that a blockage has occurred in the feeding hopper 1, thereby opening the electric telescopic rod 3.

Through the above structure, the device can detect the material flow, so that the staff can control the amount of material added.

[0026] In summary: when using the anti-blocking boiler feeding device, the user can first connect the feeding pipe 7 to the boiler and turn on the feeding motor 11. At this time, the feeding motor 11 can drive the auger structure 12 to rotate. The user can add biomass pellet fuel or other granular fuel materials into the feeding hopper 1.
