Embodiment approach

[0040] As an embodiment of the present invention, a sleeve 312 is hinged in the L-shaped through hole 311 , and a rope 33 slides through the sleeve 312 , and the sleeve 312 can swing freely under the drive of the rope 33 . When the rotating shaft 31 is shaking up and down, the angle of the rope 33 at the exit of the L-shaped through hole 311 of the rotating shaft 31 will change. At this time, the rope 33 can drive the sleeve 312 to rotate, thereby reducing the distance between the rope 33 and the exit of the L-shaped through hole 311. The friction at the place increases the service life of the rope 33.

[0041] As an embodiment of the present invention, the No. 1 wall scraping plate 36 includes an arc-shaped plate 361 and a No. 2 cylinder 362; the adjacent arc-shaped plates 361 are connected by the No. 2 cylinder 362, and a plurality of arc-shaped The connection between the plate 361 and a plurality of No. 2 cylinders 362 forms a complete No. 1 scraper plate 36; the No. 2 cyli...

Abstract

The invention belongs to the technical field of environment protection and particularly relates to a recycling process of pulverized coal ash. A recycling device used by the recycling process comprises a shell and also comprises an extruding mechanism, a mixing mechanism, a feeding opening, a feeding pipe, a conveying channel, a first electromagnetic switch, a driving device and a controller, wherein the controller is used for controlling operation of equipment; the shell is of a horizontally arranged cylindrical structure; an inner bottom wall of the shell is conical; the pulverized coal ashis bonded with solid fuels through adhesives and is treated by the recycling device; about 1-25% of effective heat value in the pulverized coal ash can be fully reused, so that the coal energy can bereused; meanwhile, plastic wastes and animal wastes can be used as the solid fuels, so that the wastes are further used, and the resources are saved; through holes are poked on finished blocks, and sulfur powder are sprinkled into the through holes; the ignition points of finished products are reduced; the finished products can be rapidly ignited; meanwhile, the combustion of the finished productsis more complete.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a fly ash resource recovery process. Background technique [0002] At present, with the advancement of science and technology, people have begun to pay attention to the rational utilization of industrial waste resources. If industrial waste is not treated, it will endanger the local ecological environment and seriously affect human life. If it is scientifically The production and processing of fly ash not only protects the environment, but also utilizes resources. There are many ways to utilize fly ash at this stage. [0003] Since fly ash is produced after coal combustion, 1-25% of combustibles still remain in it, so it can be mixed with solid fuels to form combustibles, and the high heat energy of solid fuels can be used to treat pulverized coal. The combustibles in the ash are reused, and the recovered heat energy is high. However, in the prior art...
