Automatic fly ash transfer device suitable for small-sized coal-fired power plant

Abstract

The invention provides an automatic fly ash transfer device suitable for a small-sized coal-fired power plant, and belongs to the technical field of fly ash transfer devices. The device comprises a base and a charging piece, a rotating shaft is rotationally connected to the base, the rotating shaft is fixedly provided with an intermittent piece, a rotating disc and a conversion piece in sequence and in a sleeving mode, the side surface of a shaft of the rotating disc is uniformly provided with grooves, movable grooves are uniformly formed in the front surface of the rotating disc, stabilizingmechanisms are movably arranged in the movable grooves, and a centrifugal driving mechanism is arranged on the conversion piece. According to the automatic fly ash transfer device suitable for the small-sized coal-fired power plant, the rotating disc is used for driving the charging piece through the grooves on the rotating disc, meanwhile, the stabilizing mechanisms are combined to automaticallycomplete the timed and quantitative discharge and transfer of fly ash, so that the flying situation of the fly ash caused by a large amount of movement of the fly ash is effectively reduced, the harmof the fly ash to the health of people and the pollution to the environment are greatly reduced, and the device is very suitable for small-sized coal-fired power plants and similar fly ash generationplaces.

Description

technical field [0001] The invention relates to the technical field of fly ash transfer devices, in particular to an automatic fly ash transfer device suitable for small coal-fired power plants. Background technique [0002] Fly ash is mainly composed of tiny ash particles discharged during coal combustion. Fly ash will affect people's health and cause pollution to the environment. However, because fly ash contains chemical components such as sulfur dioxide, aluminum oxide and iron oxide , can be used to make cement and various lightweight building materials, so the collection and reuse of fly ash is the best of both worlds, such as collecting fly ash from the flue gas of coal-fired power plants and transferring them to fixed storage or the location to be transported. [0003] At present, the transfer of fly ash after collection is generally carried out by pneumatic ash, but the requirements for the conveying device are relatively high, and the cost and energy consumption a...

AI Technical Summary

Problems solved by technology

[0003] At present, the transfer of fly ash after collection is generally carried out by pneumatic ash, but the requirements for the conveying device are relatively high, and the cost and energy consumption are relatively large. It is mainly suitable for large coal-fired power plants and other places. For small coal-fired It is not suitable for power plants or other places that generate a relatively small amount of fly ash.

[0004] At present, some small coal-fired power plants or other places that produce a relatively small amount of fly ash mainly collect a large amount of fly ash and then unload the collected fly ash from the collection device into the transportation device at one time. Transport it to the designated storage location through the transportation device, unload it from the transportation device, and then choose to transfer and pack the fly ash according to the needs of the customer or directly transport it to the location designated by the customer, because the fly ash is very easy to raise dust , so it will be affected by the unloading method, the number of transfers and the stability of transfer, resulting in a large amount of fly ash flying into the air, affecting human health and polluting the environment
