Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

It should be noted that, in the description of the technical solutions of the present invention, some directional words, such as "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", etc., used for clearly describing the technical features of the present invention are all according to the orientation of the drawings of the present invention.

Examples

As shown in fig. 1, the kiln for the precious metal recovery system of the embodiment comprises a kiln body 1, a stirring device 2 and a material conveying device 4, wherein the kiln body 1 comprises a kiln wall 12 and an end cover 11 for sealing an upper end opening of the kiln wall 12, the end cover 11 is hinged with the kiln wall 12, and a worker can open the end cover 11 according to needs so as to clean or replace parts and the like. The end cover 11 is provided with a smoke exhaust pipe 3, and smoke generated in the incineration process is exhausted into a special treatment device through the smoke exhaust pipe 3 to be treated so as to avoid directly exhausting into air to pollute the environment. The filter screen 6 is arranged at the bottom of the furnace wall 12, and the filter screen 6 is detachably connected with the furnace wall 12, so that the filter screen 6 can be taken down regularly for cleaning, and the filtering effect is ensured. An incineration chamber 7 is arranged below the filter screen 6, and the bottom of the incineration chamber 7 is communicated with an incinerator. In addition, the fan 5 is arranged above the side wall of the furnace wall 12 in the embodiment, the fan 5 is communicated with the inside of the furnace body 1, the fan 5 is started during incineration to blow air into the inside of the furnace body 1, so that enough oxygen is kept, and the incineration effect is increased. Because the high temperature that burns the production makes furnace body 1 and the space temperature around the furnace body 1 rise easily, and the heat effluvium reduces the effect of burning, also can make the workman be difficult to endure the high temperature environment summer simultaneously, so end cover 11 and oven 12 adopt the vacuum sandwich structure in this embodiment, and the heat insulating ability is good.

The stirring device 2 of this embodiment includes motor 21, control shaft 25, stirring piece 23 and rotation axis 22, and control shaft 25 is the horizontal setting, and one end stretches out furnace body 1 and links to each other with motor 21, and rotatable connection rotation axis 22 of the other end, rotation axis 22 and control shaft 25 mutually perpendicular, and stirring piece 23 links firmly on rotation axis 22. In this embodiment, two stirring plates 23 are symmetrically disposed on the rotating shaft 22 for stirring the material to burn the material uniformly. The stirring piece 23 is provided with a plurality of uniformly distributed stirring teeth 24, the stirring teeth 24 are in a frustum shape, the distance between the top end and the filter screen 6 is 5-20mm, the end diameter of the stirring teeth 24 close to the filter screen 6 is smaller than the end diameter of the stirring teeth 24 fixedly connected to one end of the stirring piece 23, resistance encountered during stirring can be reduced by adopting the structure, abrasion of materials to the stirring teeth 24 is reduced, and more uniform stirring can be ensured.

The feeding device 4 of this embodiment comprises a feeding port 41 and a feeding track 42 connected with each other, the feeding port 41 is opened at the upper part of the furnace wall 12 and used as a material inlet, and one side of the feeding track 42 is fixedly connected to the inner side wall of the furnace wall 12 and is spirally arranged from top to bottom. Specifically, one side of the material conveying track 42 is fixedly connected with the inner side wall of the furnace wall 12, and the other side of the material conveying track is bent upwards to form a baffle plate, so that the materials are prevented from falling in the conveying process. By adopting the material conveying device 4, materials enter the furnace body 1 from the feeding hole 41 and are conveyed downwards along the spiral conveying track 42, and are gradually preheated in the process, so that the materials are heated more quickly during incineration and are more fully incinerated.

The utility model discloses a kiln for noble metal recovery system can preheat in advance before the material burns to intensive mixing when burning makes the material can not appear piling up the phenomenon, makes simultaneously to burn more evenly abundant, burns efficiently, can further improve the recycle ratio of the energy.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
