[0002] Gold smelting is the process of converting gold-containing ore or waste into pure gold or gold alloy. A large amount of wastewater is generated during the gold smelting process. In order to recover the small amount of gold minerals mixed in the wastewater and filter out impurities such as ore mud, the wastewater needs to be filtered during the wastewater treatment process. However, in the prior art, solid wastes such as gold minerals and ore mud blocked in the filter device need to be manually cleared out, which is very inconvenient. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a filtering device for gold smelting, which lifts the slag blocks accumulated on the inner side of the funnel-shaped filter cloth support frame upward through a spiral conveyor shaft, and discharges them through a discharge pipe for collection, so as to facilitate the recovery of solid waste such as residual gold components and ore mud in the wastewater.

[0005] The beneficial effects of the utility model are as follows: when the device is used, the wastewater to be filtered is discharged into the filter bin through the water inlet pipe, the slag blocks mixed in the wastewater are blocked by the filter cloth, and accumulated on the inner side of the funnel-shaped filter cloth support frame, and at the same time, the wastewater except for large particles of waste impurities and residual gold components filtered out by the filter cloth is input into the secondary filtration device through the intermediate water pipe, and is filtered again by the activated carbon filter element and the molecular sieve filter element, and the harmful components and small particles of impurities in the wastewater are adsorbed and filtered, thereby improving the wastewater filtration effect and simplifying the subsequent purification work.

[0006] The slag blocks accumulated on the inner side of the funnel-shaped filter cloth support frame and above the filter cloth can be automatically discharged and collected. It only needs to control the operation of the drive motor. The operation of the drive motor drives the second pulley to rotate, and the second pulley pulls the first pulley to rotate through the belt, thereby driving the spiral conveyor shaft to rotate. The slag blocks accumulated on the inner side of the funnel-shaped filter cloth support frame are lifted upward by the spiral conveyor shaft and discharged through the discharge pipe for collection, which is convenient for the recovery of solid waste such as residual gold components and ore mud in the wastewater.

[0009] The beneficial effect of this improvement is that when it is necessary to thoroughly clean the impurities on the inner side of the funnel-shaped filter cloth support frame and above the filter cloth, the sealing plate can be opened to clean out the remaining impurities.

[0010] In order to adsorb and filter the remaining small particles and harmful components in the wastewater:

[0011] As a further improvement of the above technical solution: a filter element insertion installation frame is inserted and installed inside the secondary filtration device, and an activated carbon filter element and a molecular sieve filter element are inserted and installed inside the filter element insertion installation frame.

[0012] The beneficial effect of this improvement is that the activated carbon filter element and the molecular sieve filter element are used to adsorb and filter the small particle impurities and harmful components remaining in the wastewater.

[0013] To facilitate the push and pull of the filter element into the installation frame:

[0016] To limit the insertion of the filter element into the installation frame:

[0017] As a further improvement of the above technical solution: a limit pin is installed on the front side of the secondary filtering device.

[0018] The beneficial effect of this improvement is that the limit pin is used to limit the insertion of the filter element into the installation frame to prevent it from sliding outwards.

[0019] For wastewater discharge:

[0020] As a further improvement of the above technical solution: a drain pipe is connected to the bottom of the secondary filtering device, and the bottom of the drain pipe is connected to a valve.

[0021] The beneficial effect of this improvement is that the wastewater that has entered the secondary filtration device and completed filtration can be discharged by opening the valve.
