Description

Technical Field

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

[0002] The main sources of fly ash are coal-fired power plants and urban central heating boilers, of which more than 90% are wet ash, which has lower activity than dry ash, wastes water and electricity, pollutes the environment, and is not conducive to comprehensive utilization. In order to better protect the environment and facilitate the comprehensive utilization of fly ash, and considering the maturity of dust removal and dry ash transportation technology, dry ash collection has become the development trend of fly ash collection in the future, and fly ash recovery and treatment equipment is often used in the treatment of fly ash.

[0003] A fly ash recovery and processing device with publication number CN215390642U includes a feed hopper, a barrel body is fixedly installed on the bottom outer wall of the feed hopper, and a screen baffle is fixedly connected to the inner wall of the barrel body, and an air inlet pipe is fixedly connected to the right inner wall of the barrel body, and a blower is fixedly installed on the right side of the air inlet pipe, and a support plate is fixedly connected to the inner wall of the barrel body, and a fixed inclined plate is fixedly connected to the top of the support plate. In the fly ash recovery and processing device, after the screen baffle processes the fly ash once, the coal slag with a small amount of fly ash slides to the surface of the screening plate, and at the same time, the motor drives the rotating shaft, which in turn drives the centrifugal rotating plate to hit the shaking plate, and then shakes the screening plate to separate the coal slag from the fly ash attached to the coal slag, thereby facilitating the screening and processing of the fly ash, and facilitating the recycling of the fly ash after separation, thereby reducing the difficulty of utilizing the fly ash and increasing the use value of the recovery device. In addition, the existing recovery and processing device also has the following disadvantages during use:

[0004] (1) The existing recycling and processing device is not equipped with a feeding structure, and cannot pre-crush the fly ash. Since fly ash will produce small solid particles when it is piled up and stored, it cannot be crushed by simply vibrating the screen, thereby reducing the quality and efficiency of screening. In severe cases, fly ash will accumulate at the feed port;

[0005] (2) The existing recycling and processing device does not have a detachable filter inside the blower, which causes the particles in the air to come into hard contact with the fan blades during the operation of the blower, thereby reducing the service life of the blower;

[0006] (3) The screen baffle in the existing recycling and processing device is not provided with a cleaning structure, resulting in a decrease in the dust filtering effect of the screen baffle. Utility Model Content
