[0002] Gold smelting refers to the process of extracting gold from ores containing metallic gold. It usually includes steps such as crushing, grinding, refining and refining, and finally separates metallic gold from the ore. Gold smelting produces a large amount of waste gas. The main purpose of waste gas treatment is to reduce pollution to the environment, and sometimes it also involves recovering valuable substances;
[0003] Exhaust gas enters the exhaust gas treatment unit through the air intake pipe. Gold smelting not only produces exhaust gas, but also contains particulate matter and impurities.

However, the particulate matter and impurities carried in the exhaust gas can easily cause congestion to the interception components, so the interception components need to be cleaned and replaced frequently, which is complicated and inconvenient to operate. In addition, the exhaust gas treatment unit needs to be shut down for operation when cleaning and replacing the interception components, which will delay and affect the treatment of the exhaust gas, thereby affecting the efficiency of the exhaust gas treatment.

DETAILED DESCRIPTION
[0017] See also Figure 1-Figure 4The utility model provides the following technical solutions: it includes an exhaust gas processor body 1, an exhaust gas intake pipe 11 and a clean gas exhaust pipe 12, a notch 13 is provided on one side of the exhaust gas processor body 1, and a rotating box 2 is rotatably connected to the inner wall of the notch 13, and a plurality of capture bins 21 are provided on the rotating box 2, and interception nets 22 are arranged in the plurality of capture bins 21, and the plurality of capture bins 21 are connected with the inner space of the exhaust gas intake pipe 11 in sequence, a shunt pipe 3 is fixedly connected to the bottom end of the clean gas exhaust pipe 12, and a conical diffusion cover 31 is fixedly connected to the bottom end of the shunt pipe 3, and a valve is installed on the shunt pipe 3, and the capture bins 21 are connected with the inner space of the conical diffusion cover 31 in sequence, and a receiving groove 14 is provided on the exhaust gas processor body 1, and a connecting port 141 is provided between the accommodating groove 14 and the notch 13, and the capture bins 21 are spatially docked with the connecting port 141 in sequence.
[0018] In this embodiment: the exhaust gas processor body 1 supports the various components of the device, the exhaust gas processor body 1 accommodates the rotating box 2 through the recess 13, and the rotating box 2 is connected with the exhaust gas intake pipe 11 in sequence through a plurality of capture chambers 21, so that the exhaust gas and particulate matter guided by the exhaust gas intake pipe 11 can pass through the capture chamber 21 and then enter the gas filtration process inside the exhaust gas processor body 1, and the capture chamber 21 intercepts the particulate matter and impurities in the exhaust gas through the interception net 22. After the interception net 22 intercepts the particulate matter and impurities, the particulate matter and impurities remain inside the capture chamber 21 When the interception net 22 inside the capture bin 21 needs to be cleaned and replaced, the rotating box 2 is controlled to rotate, and the rotating box 2 drives the next capture bin 21 and the interception net 22 to intercept and filter the exhaust gas intake pipe 11. The captured bin 21 and the interception net 22 after use rotate to reach the position below the clean gas exhaust pipe 12. At this time, the receiving tank 14 is connected with the internal space of the capture bin 21 through the connecting port 141, so that the particulate impurities retained in the capture bin 21 can fall into the internal space of the receiving tank 14 through the connecting port 141 for centralized storage. The gas filtered by the interception net 22 is purified in each purification process inside the exhaust gas processor body 1 in turn, and finally the clean gas is discharged through the clean gas exhaust pipe 12. The internal space of the clean gas exhaust pipe 12 is connected with the internal space of the diverter pipe 3. The diverter pipe 3 and the conical diffusion cover 31 are located above the capture bin 21, so that when the particles and impurities retained in the capture bin 21 are discharged downward, the airflow inside the clean gas exhaust pipe 12 can be diverted into the diverter pipe 3 by opening the valve on the diverter pipe 3. The diverter pipe 3 guides the airflow downward, and the conical diffusion cover 31 guides the airflow downward. The airflow expands the range of action so that the interception net 22 can be fully covered by the airflow. The airflow blows the interception net 22 from top to bottom, so that the interception net 22 can obtain a backblowing effect, which makes it easier for the particles and impurities retained and attached under the interception net 22 to be discharged into the containing tank 14, thereby achieving a cleaning effect on the interception net 22, reducing the frequency of manual cleaning, thereby reducing manpower expenditure, and cleaning and replacement operations can be carried out without shutting down the device, effectively improving the effective working time of the exhaust gas purification treatment and improving the work efficiency of the exhaust gas treatment and purification.
[0019] A support ring 221 is detachably connected to the top of the interception net 22, and the support ring 221 is fixedly connected to the inner wall of the corresponding capture bin 21; the rotating box 2 supports the support ring 221, and the support ring 221 supports the interception net 22. By installing and disassembling the interception net 22 at the bottom of the support ring 221, it is convenient to replace the interception net 22.
[0020] A yield groove 23 is provided at the bottom end of the rotating box 2, and a driving motor 131 is installed at the top of the groove 13, and the output end of the driving motor 131 is fixedly connected to the inner wall of the yield groove 23; the yield groove 23 gives way to the driving motor 131, and the driving motor 131 drives the rotating box 2 to rotate, so that the rotating box 2 can switch between several capture bins 21 and interception nets 22.
[0021] A containing box 4 is slidably connected inside the containing groove 14, and the top opening of the connecting port 141 corresponds to the position of the connecting port 141; the containing groove 14 contains the containing box 4 as a whole, and the containing box 4 can be taken out from the inside of the connecting port 141, and the particles and impurities falling through the connecting port 141 can fall into the inside of the containing box 4 for collection and storage, thereby facilitating the removal of the particles and impurities and centralized processing.
[0022] An overflow net 41 is fixedly connected to one side of the containing box 4, and the overflow net 41 discharges the excess gas inside the containing box 4. A handle 42 is fixedly connected to one side of the containing box 4. After the shunt pipe 3 guides the airflow to blow back the interception net 22, the airflow enters the inside of the containing box 4. The air pressure inside the containing box 4 increases, and the air pressure discharges excess air through the overflow net 41, thereby preventing the airflow guided by the shunt pipe 3 from being turbulent. The handle 42 is convenient for the staff to install and remove the containing box 4.
[0023] The working principle and use process of the utility model are as follows: when the device is in use, the waste gas and particulate impurities generated by gold smelting are introduced into the waste gas processor body 1 through the waste gas intake pipe 11, and the waste gas enters the corresponding capture bin 21. The capture bin 21 intercepts the particulate matter and impurities in the waste gas through the interception net 22. After the interception net 22 intercepts the particulate matter and impurities, the particulate matter and impurities remain in the internal space of the capture bin 21. The gas filtered by the interception net 22 is purified in each purification program inside the waste gas processor body 1 in turn, and finally the clean gas is discharged through the clean gas exhaust pipe 12. When the interception net 22 needs to be cleaned or replaced, the control drive motor 131 drives the rotating box 2 to rotate, and the rotating box 2 drives the next capture bin 21 and the interception net 22 to intercept and filter the waste gas intake pipe 11. The capture bin 2 after use 1 and the interception net 22 rotate to the position below the clean air exhaust pipe 12, and the particulate impurities retained in the capture bin 21 can fall into the internal space of the containing box 4 through the connecting port 141 for centralized storage, and then the valve on the diversion pipe 3 is opened to allow the airflow inside the clean air exhaust pipe 12 to be diverted into the diversion pipe 3, and the diversion pipe 3 guides the airflow to flow downward, and the airflow blows the interception net 22 from top to bottom, so that the interception net 22 can obtain a backblowing effect, which is convenient for the particulate matter and impurities retained and attached below the interception net 22 to be detached and discharged into the containing tank 14, thereby achieving the cleaning effect of the interception net 22, reducing the frequency of manual cleaning, thereby reducing manpower expenditure, and can perform cleaning and replacement operations without stopping the device, effectively improving the effective working time of the exhaust gas purification treatment, and improving the work efficiency of the exhaust gas treatment purification.
