Problems solved by technology

[0002] The methods for processing waste incineration fly ash mainly include cement solidification, melting solidification, asphalt solidification, chemical stabilization treatment, acid or other solvent washing methods, etc. Melting technology is an emerging fly ash treatment technology in recent years. Compared with cement solidification and other methods , the harmless degree of the melting treatment technology is thorough, the product stability is high, the operating cost is moderate, the weight reduction is significant, and the fly ash can be transformed into non-toxic and stable slag to be used as roadbed and other building materials; but the existing fly ash The melting temperature required by the ash melting device is relatively high, and the requirements for the material of the equipment are relatively high; moreover, its melting and solidification effect is not good, and it cannot well meet the needs of use

Embodiment 1

[0029] Such as Figure 1-2 As shown, in the embodiment provided by the present invention, a melting device for fly ash solidification includes a shell 1, the side wall of the shell 1 has an interlayer 2, and the inner spiral of the interlayer 2 is provided with a spiral heat sink. The oil delivery pipe 3, the bottom of the housing 1 has a hot oil inlet pipe 4 communicating with the feed port at the bottom end of the spiral hot oil delivery pipe 3, the hot oil inlet pipe 4 is provided with a first control valve 5, The other side of the top of the housing 1 has a hot oil outlet 13 communicating with the interlayer 2;

[0030] Further, in the embodiment provided by the present invention, the inner cavity of the housing 1 is fixedly installed with an inner cylinder 14, and the outer wall of the inner cylinder 14 has an electromagnetic heater 15;

[0031] A stirring mechanism is provided along the central axis in the inner cylinder 14, and a stirring motor 17 for driving the stirr...

Embodiment 2

[0040] Such as figure 1 with Figure 4 As shown, the difference from Embodiment 1 is that in the embodiment provided by the present invention, the rotating cloth assembly also includes a support cylinder 22 coaxially fixed on the rotating disk 16, and the inner ring of the support cylinder 22 is fixed A driven toothed disc 21 is provided, and a driving toothed disc 20 engaged with the driven toothed disc 21 is fixedly mounted on the stirring shaft 24 in the support cylinder 22. Therefore, when the stirring motor 17 drives the stirring shaft 24 to rotate At this time, under the mutual engagement between the driving toothed plate 20 and the driven toothed plate 21, the rotary plate 16 can be pushed to rotate, therefore, through the first feeding funnel 18 or the second feeding funnel 19, it is put into the top of the inner cylinder 14 When the material in the cavity enters the lower inner cavity of the inner cylinder body 14 through the material distribution hole 23, the effect...

Abstract

The embodiment of the invention relates to the technical field of fly ash treatment and particularly discloses a melting device for fly ash solidification. The melting device comprises a shell. The interior of the side wall of the shell is provided with an interlayer. A spiral hot oil conveying pipe is arranged in the interlayer in a spiral surrounding mode. An inner barrel is fixedly installed ina shell inner cavity, and the outer wall of the inner barrel is provided with an electromagnetic heater. A stirring mechanism is arranged in the inner barrel along the central axis, and a stirring motor is installed on a top plate of the shell and is used for driving the stirring mechanism to rotate. The top of the inner barrel is provided with a rotary distribution assembly. Through the meltingdevice provided by the embodiment of the invention, a very good heating effect can be achieved for a barrel, and thus a melting effect is ensured. When materials put into an top cavity of the inner barrel through a first feed funnel or a second feed funnel enter a lower inner cavity of the inner barrel through a distribution hole, an even feeding effect can be achieved.
