Description

Technical Field

[0001] This utility model relates to the field of peak-shaving material conveying anti-blockage technology, and in particular to a peak-shaving material conveying system. Background Technology

[0002] In the field of thermal power generation, peak-shaving fuel supply systems need to precisely control the amount and timing of fuel delivery according to the grid's dispatch instructions in order to enable units to quickly increase or decrease load. For example, during deep peak shaving, when it is necessary to reduce the unit load, the peak-shaving fuel supply system must reduce the supply of high-quality fuel and / or input low-quality coal; when it is necessary to quickly restore the load, it must promptly increase the amount of high-quality fuel delivered to ensure the stable operation of the unit.

[0003] Due to the diversity of low-quality coal, when the material has high moisture content, it is difficult to flow and tends to stick to the inner wall, which can easily lead to poor material discharge, blockage, and affect fuel transportation efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a blockage-prevention and peak-shaving material conveying system.

[0005] This utility model is implemented as follows: a peak-shaving material conveying system includes a silo and a partition plate installed inside the silo. The partition plate divides the silo into silo A and silo B. The outlets of silo A and silo B are equipped with a rotating anti-blocking mechanism, and a conveyor is installed below the outlet of the rotating anti-blocking mechanism.

[0006] The conveyor is equipped with a cover, and the cover is provided with a receiving port corresponding to the rotating anti-blocking mechanism. The cover is also provided with a discharge port.

[0007] A slide valve is provided between the rotating anti-blocking mechanism and the material receiving port.

[0008] The rotating anti-blocking mechanism is misaligned and installed at the outlets of silos A and B.

[0009] The outlet of the rotating anti-blocking mechanism is connected to a feed meter.

[0010] The rotating anti-clogging mechanism includes a housing mounted on the hopper, the housing having a central hole matching the hopper's discharge port, a toothed disc rotatably connected to the housing, a drive mechanism for driving the toothed disc to rotate on the housing, and a clearing scraper on the inner side of the toothed disc.

[0011] The rotating anti-blocking mechanism adopts the anti-blocking device with patent number 2024203182725 applied for by the applicant.

[0012] The partition plate of this invention divides the raw coal bunker into two parts, which can be equipped with different types of coal. Different types and proportions of coal can be quickly switched according to the operating load requirements of the boiler. It is applied to the flexible modification of the operating load of power plant boilers. The drive mechanism is started periodically, which drives the toothed disc to rotate. The toothed disc drives the cleaning scraper to rotate, breaking up and scraping off the material adhering to the inner wall. The drive mechanism can rotate in both directions to scrape off the lumps or materials adhering to the inner wall. Attached Figure Description

[0022] The outlet of the rotating anti-blocking mechanism is connected to a feed meter 28.

[0023] The rotating anti-blocking mechanism includes a housing 7 mounted on the hopper, the housing 7 having a central hole 12 matching the hopper's discharge port, a geared disc 8 rotatably connected inside the housing 7, a drive mechanism 5 for driving the geared disc 8 to rotate on the housing 7, and a clearing scraper 4 on the inner side of the geared disc; the rotating anti-blocking mechanism adopts the anti-blocking device of the applicant's patent application number 2024203182725.

[0024] The partition plate of this invention divides the raw coal bunker into two parts, which can be equipped with different types of coal. Different types and proportions of coal can be quickly switched according to the operating load requirements of the boiler. It is applied to the flexible modification of the operating load of power plant boilers. The drive mechanism is started periodically, which drives the toothed disc to rotate. The toothed disc drives the cleaning scraper to rotate, breaking up and scraping off the material adhering to the inner wall. The drive mechanism can rotate in both directions to scrape off the lumps or materials adhering to the inner wall.
