Description
Technical Field
The utility model relates to the technical field of hydrometallurgy, in particular to a dust collection and exhaust system for a gold and silver casting process.
Background
In the prior art, in the process of casting gold powder and silver powder into gold ingots and silver ingots, generated tail gas needs to be absorbed and treated to be discharged, and a workshop universal degassing and dust removing system is directly adopted, so that fine and dry gold powder and silver powder materials are sucked into the degassing and dust removing system due to high negative pressure, and the loss of precious metal materials is directly caused.
In summary, the utility model provides a dust collection and exhaust system for gold and silver casting procedures.
Disclosure of Invention
The utility model aims to provide a dust collection and exhaust system for a gold and silver casting process.
The dust collection and exhaust system for gold and silver casting procedures comprises a casting furnace, wherein the upper end of the casting furnace is provided with a negative pressure protection support, the left side, the right side and the rear side of the upper part of the negative pressure protection support are closed, the upper end of the negative pressure protection support is also connected with an air inlet pipe, the other end of the air inlet pipe is connected with a cloth bag dust collector, the other side of the cloth bag dust collector is connected with an exhaust pipe, the exhaust pipe is communicated with the outside, the cloth bag dust collector is supported by the support, the lower end of the cloth bag dust collector is provided with a chute, the chute is conical, and the end part of the chute is provided with a valve for discharging materials.
Further, the left side and the right side of the upper part of the negative pressure protection support are also provided with side plates in an inward inclined manner, the lower ends of the side plates are provided with T-shaped grooves, and the T-shaped grooves are in sliding connection with T-shaped protrusions arranged on the casting furnace.
The beneficial effect of above-mentioned scheme is:
1. the method avoids that larger negative pressure directly acts on noble metal materials, and reduces the loss of the materials;
2. purifying tail gas generated by casting, and reaching the emission standard;
3. opening a valve, and directly discharging the collected materials into casting equipment;
4. the material is recovered, so that the loss of the material is reduced;
5. the tail gas reaches the emission standard;
6. the dust collection rate is high, and the dust collection material can be remelted.
Drawings
FIG. 1 is a schematic diagram of the main structure of the present utility model;
fig. 2 is an enlarged schematic view of a portion a in fig. 1.
In the figure: 1. a casting furnace; 2. a negative pressure protection bracket; 3. an air inlet pipe; 4. a cloth bag dust collector; 5. a bracket; 6. an exhaust pipe; 7. a side plate; 8. t-shaped protrusions; 9. a chute; 10. a valve; 11. a T-shaped groove.
Detailed Description
The utility model will be further clarified and fully described in connection with the accompanying drawings, to which the scope of protection of the utility model is not limited.
Example 1:
as shown in fig. 1 to 2, a dust collection and exhaust system for gold and silver casting procedures comprises a casting furnace 1, wherein a negative pressure protection support 2 is arranged at the upper end of the casting furnace 1, the left side, the right side and the rear side of the upper part of the negative pressure protection support 2 are closed, the upper end of the negative pressure protection support 2 is also connected with an air inlet pipe 3, the other end of the air inlet pipe 3 is connected with a cloth bag dust collector 4, the other side of the cloth bag dust collector 4 is connected with an exhaust pipe 6, the exhaust pipe 6 is communicated with the outside, the cloth bag dust collector 4 is supported by a support 5, a chute 9 is arranged at the lower end of the cloth bag dust collector 4, the chute 9 is in a conical shape, and a valve 10 is arranged at the end part of the chute 9 for discharging materials.
In this embodiment, the left and right sides of the upper portion of the negative pressure protection support 5 are further provided with side plates 7 in an inward inclined manner, the lower ends of the side plates 7 are provided with T-shaped grooves 11, and the T-shaped grooves 11 are slidably connected with T-shaped protrusions 8 provided on the casting furnace 1.
Specifically, when the utility model is used, through the interval arrangement of the air inlet pipe 3 and the casting furnace 1, the gold powder or silver powder is not easy to be directly sucked into the air inlet pipe 3 under the action of negative pressure in the casting state in the casting process of the casting furnace 1, so that a great amount of loss of materials and damage of equipment are caused, but a small amount of loss of the gold powder or silver powder still cannot be avoided, so that the bag dust collector 4 is further arranged at the rear end to collect the finely dried gold powder or silver powder materials, thereby further reducing the loss.
The embodiments of the present utility model are disclosed as preferred embodiments, but not limited thereto, and those skilled in the art will readily appreciate from the foregoing description that various extensions and modifications can be made without departing from the spirit of the present utility model.
