Description

Technical Field

[0001] The utility model belongs to the technical field of fly ash recovery, in particular to a fly ash recovery and reuse device. Background Art

[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged from coal-fired power plants. Fly ash particles have a porous honeycomb structure, a large specific surface area, and high adsorption activity. When recycling fly ash, it is necessary to set up ash collection sites around the coal-fired power plants to collect the raw materials. The collected fly ash also needs to be screened for subsequent use and treatment.

[0003] Before common fly ash recycling and reuse, fly ash needs to be screened to remove impurities and unburned coal blocks to facilitate subsequent processing. Since fly ash is light in weight, it is easy to adhere to the surface of the screening equipment, which can easily cause the sieve holes to be blocked, affecting the screening effect and causing waste of raw materials. To this end, we provide a fly ash recycling and reuse device to solve the above technical problems. Utility Model Content

The driving device is used to drive the knocking drive column 201 to rotate, so that the transmission column 209 slides back and forth along the transmission guide groove 203. Since the transmission guide groove 203 is a wavy groove structure, the transmission column 209 drives the transmission block 207 to slide up and down along the sliding guide column 205, and then the transmission block 207 drives the L-shaped support plate 208 to move up and down synchronously, and the knocking hammer 202 moves up and down reciprocatingly. When the knocking hammer 202 falls and contacts the horizontal sieve plate 101, the horizontal sieve plate 101 is knocked.

The knocking hammer 202 knocks the horizontal sieve plate 101, and the vibration spring 103 is squeezed or stretched. Through the up and down vibration of the vibration spring 103, the appropriate fly ash is shaken off, and the horizontal sieve plate 101 is kept unblocked.

[0035] When fly ash adheres to the inner wall of the discharge chamber, the driving motor 307 is used to drive the threaded rod 306 to rotate. Under the cooperation of the threaded rod 306 and the corresponding support block thread, the distance between the two support blocks is changed, and at the same time, the support block drives the first adjusting link 302 and the second adjusting link 303 to rotate synchronously, so that the angle between the first adjusting link 302 and the second adjusting link 303 changes, so that the cleaning scraper 301 slides along the lower surface of the cross support frame 304 until the cleaning scraper 301 fits against the inner wall of the discharge chamber. At the same time, the cleaning component 3 rotates synchronously with the knocking drive column 201. The cleaning scraper 301 scrapes and cleans the fly ash attached to the inner wall of the discharge chamber during the rotation to avoid waste of raw materials.
