Background
In the production process of the pyrometallurgical copper smelting, a large amount of smelting smoke dust is carried in the smoke generated by the smelting furnace. Valuable metals such as copper and the like contained in the smoke dust are collected by a dust collection system and then returned to a smelting furnace or mixed into raw materials for recycling, so that the smoke dust collected by each dust collection point needs to be sent to a smoke dust bin in the smelting furnace or a raw material warehouse. Moreover, whether the smoke dust system is normal or not is directly related to the production operation of the smelting system, so that a practical and reliable smoke dust treatment method is selected, and valuable metals in the smoke dust are recovered, which is an important factor that must be considered in a copper smelting plant.
The method for treating the fine dust by large domestic smelting enterprises mainly comprises the step of conveying the smoke dust into a smoke dust bin through a positive pressure concentrated phase pneumatic conveying system. The method has the disadvantages of high manufacturing cost, high maintenance requirement and complex control of the whole system. In addition, when the pipeline is blocked, a large amount of dust can be generated when the pipeline is dredged, a lot of dust pollution can be brought to the environment of a factory, and the requirement of clean production cannot be met.
In China, many copper smelting enterprises drop smoke generated by a smelting furnace into a smoke tank (ash tank) through dust collection equipment, then the smoke is conveyed to a smoke bin by a forklift, and the smoke bin is fully stirred with raw materials through a feeding travelling crane, then enters a belt conveyor through a hopper, and finally returns to the smelting furnace. The method has the disadvantages that because the operation environment is open, a large amount of dust can be generated in the process of pouring the fine dust in the dust tank into the dust bin and stirring the dust and the raw materials, not only can a large amount of environmental pollution be caused, but also certain influence can be caused on the bodies of workers in the raw material factory.
No matter the smoke dust is sent to the smoke dust bin through the concentrated phase pneumatic conveying system or the ash tank to return to the furnace, the operation steps are complicated in the process, and the problems that the working environment is deteriorated and the environmental protection requirement cannot be met exist.

Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
Example (b):
referring to fig. 1, the embodiment provides an environment-friendly device for treating fine dust in a copper smelting plant, which comprises a conveyor belt 1, a front raw material blanking port 2 and a rear raw material blanking port 3 which are arranged above the conveyor belt 1, and further comprises an ash adding mechanism 4 arranged between the front raw material blanking port 2 and the rear raw material blanking port 3, wherein the ash adding mechanism 4 comprises a cover 41 covered on the conveyor belt 1, a screw conveyor 42 arranged on the cover 41 and communicated with the interior of the cover 41 through a discharge port, an ash storage bin 43 arranged on the screw conveyor 42 and connected with the feed port of the screw conveyor 42 through a discharge port, and an ash tank 44 arranged at the inlet of the ash storage bin 43, wherein an ash outlet of the ash tank 44 is connected with an inlet of the ash storage bin 43 through soft sealing; and a bag dust collector 45 provided on the cover 41 and having an ash discharge opening communicating with the cover 41, wherein a discharge valve 451 is further provided on the ash discharge opening of the bag dust collector 45.
Wherein the inlet of the bag dust collector 45 is respectively communicated with the dust storage bin 43 and the cover 41 through a dust collecting pipeline 46; valves 461 are arranged on the dust collecting pipeline 46 and are close to the cover 41 and the dust storage bin 43.
In order to make the raw material falling from the front raw material blanking port 2 smoothly pass through the cover 41, the left and right ends of the cover 41 are formed into an arch structure for the raw material to pass through, and the cover 41 is flexibly contacted with the conveyor belt 1.
The implementation principle is as follows: for a more clear and concise description of the embodiment, the raw material falling from the front raw material blanking port 2 is referred to as a front material, and the raw material falling from the rear raw material blanking port 3 is referred to as a rear material.
In operation, the ash tank 44 with the collected fine ash is first placed on the inlet of the ash storage bin 43, and then the ash outlet of the ash tank 44 is opened, so that the fine ash in the ash tank 44 continuously falls into the ash storage bin 43, and then the fine ash in the ash storage bin 43 continuously falls into the screw conveyor 42, and the fine ash is continuously sent into the cover 41 through the screw conveyor 42, so that the fine ash continuously falls down in the cover 41.
In the above-mentioned in-process, conveyer belt 1 is constantly running, so, the head-end feed falls on conveyer belt 1, by conveyer belt 1 with the head-end feed direction transportation, when the head-end feed passes through in cover 41 along with conveyer belt 1, the head-end feed upper surface can constantly fall in cover 41 by the fine ash of screw conveyer 42 transport, so just avoided the adhesion of fine ash to falling on conveyer belt 1, conveyer belt 1 continues the operation, when moving back raw materials blanking mouth 3 department, the back-end feed then can directly fall on the fine ash of head-end feed upper surface, final head-end feed, the back-end feed, fine ash has just formed sandwich structure, fine ash is pressed from both sides in the middle of head-end feed and back-end feed, it is abundant with the raw materials mixture to have guaranteed to add fine ash, avoid fine ash to glue on the belt simultaneously and prevent to produce the raise dust in subsequent conveyer belt 1 transportation.
Moreover, in the dust adding process, when the fine dust falls into the dust storage bin 43 from the dust tank 44, the fine dust can generate raised dust, and simultaneously, under the action of the bag dust collector 45, the raised dust can be recovered into the bag dust collector 45 again through the dust collecting pipeline 46, and finally, the raised dust can fall into the cover 41 through the dust discharging opening of the bag dust collector 45, and the operation is repeated in a circulating manner, so that the raised dust generated when the fine dust falls down through the screw conveyor 42 and the raised dust generated when the fine dust falls down from the bag dust collector 45 can be effectively collected by the bag dust collector 45 again.
The above embodiment is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the technical scope of the claims.
