Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a precious metal sewage treatment device. Background Art

[0002] A large amount of wastewater will be generated during the smelting process of precious metals, and this wastewater will contain precious metals. Due to the scarcity and high price of precious metal resources, if it is directly discharged, it will not only pollute the environment but also cause waste.

[0003] In the prior art, chemical agents are first used to coagulate and settle sewage, and the condensed suspended matter will float up, and then reverse osmosis is used to remove the precious metals and the suspended matter. Finally, the treated sewage can be discharged. In the prior art, most of the suspended matter floats on the water surface, which is not convenient for centralized scooping. At the same time, after the sewage is discharged, some residual dirt and suspended matter are easy to adhere to the inner wall of the device, which requires manual cleaning, and the operation is very inconvenient.

[0004] Therefore, it is necessary to invent a precious metal sewage treatment device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precious metal wastewater treatment device, comprising a sealing box and a receiving box, the receiving box being located on one side of the sealing box, an adjusting assembly being installed between the sealing box and the receiving box, a lifting screw being installed on the upper end of the adjusting assembly, a connecting arm being connected to the external thread of the lifting screw, a filter cartridge being installed on the lower end of the connecting arm away from the lifting screw, and a sealing assembly being installed on the lower end of the filter cartridge.

[0007] Based on the above characteristics: when the adjusting component drives the lifting screw to rotate forward, the connecting arm can drive the filter cartridge to move downward so that the filter cartridge can be inserted into the sealing box; when the sealing component at the bottom of the filter cartridge contacts the bottom end of the inner cavity of the sealing box, the sewage containing precious metals can be injected into the filter cartridge, and then chemical agents are added to wait for the sewage to settle and flocculate. When the drainage time is reached, the suspended matter generated by flocculation will float on the water surface, and then the adjusting component can drive the lifting screw to reverse, and at this time the connecting arm can drive the filter cartridge to move upward. During this process, the sewage in the filter cartridge will be discharged through the sealing component, and the generated suspended matter will be isolated in the inner cavity of the filter cartridge. When the filter cartridge rotates to the top of the receiving box, the lifting screw can be stopped, and finally the sealing component can be opened so that the suspended matter in the filter cartridge can be discharged downward to the inside of the receiving box for collection.

[0008] Preferably, the adjustment assembly includes a fixed seat and a bearing seat installed on the upper end of the fixed seat, a first conical tooth is installed on the upper end of the bearing seat, and a second conical tooth is installed on one side of the fixed seat.

[0009] Based on the above characteristics: when it is necessary to drive the lifting screw to rotate forward or reverse, the second conical tooth can be driven forward or reverse first. When the second conical tooth rotates, the first conical tooth can be driven to rotate. Finally, the first conical tooth will drive the lifting screw to rotate forward or reverse.

[0010] Preferably, a movable nut is installed at one end of the connecting arm, and the movable nut is threadedly connected to the lifting screw. A fixed nut A is installed at the other end of the connecting arm, and a locking screw is threadedly connected to the middle of the fixed nut A.

[0012] Preferably, a fixing plate is installed in the middle of the upper end of the filter cartridge, connecting rods are installed around the fixing plate, and a fixing nut B is installed in the middle of the fixing plate.

[0013] Based on the above features: when the fixing nut B in the middle of the fixing plate is aligned with the fixing nut A, the locking screw can be used to penetrate the fixing nut B and the fixing nut A to lock and fix them. When disassembly is required, the locking screw only needs to be rotated to separate the fixing nut B and the fixing nut A.

[0014] Preferably, the sealing assembly includes a sealing bottom plate and a filter screen installed in the middle of the sealing bottom plate, positioning plates are symmetrically installed on both sides of the inner cavity of the sealing bottom plate, and a scraper is fixedly installed on the upper end of the positioning plate.

[0015] Based on the above features: the sealing bottom plate can be sealed under the filter cartridge. When the filter cartridge is lifted up and separated from the sealing box, the water in the filter cartridge will leak through the filter screen. When the sealing bottom plate is removed, the sealing bottom plate will drive the scraper to move synchronously through the positioning plate. At this time, the scraper can scrape the inner wall of the filter cartridge to prevent impurities and suspended matter from adhering to the inner wall of the filter cartridge.

[0016] Preferably, an external thread begins to be formed on the outside of the lower end of the filter cartridge, an internal thread is formed on the inner wall of the sealing bottom plate, and the sealing bottom plate is threadedly connected to the filter cartridge.

[0018] Preferably, an annular sealing ring is installed on the outside of the lower end of the sealing bottom plate.

[0019] Based on the above characteristics: when the filter cartridge descends into the inner cavity of the sealing box and makes the sealing bottom plate contact with the bottom of the sealing box, the annular sealing ring will seal between the sealing bottom plate and the sealing box to prevent the sewage injected into the filter cartridge from being discharged outward.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is convenient to collect the suspended matter produced by flocculation. The suspended matter produced by flocculation will float on the water surface. The adjusting component can drive the lifting screw to rotate, so that the connecting arm drives the filter cartridge to move upward. In this process, the sewage in the filter cartridge will leak through the filter screen, and the suspended matter produced will be isolated in the inner cavity of the filter cartridge. When the filter cartridge rises and leaves the sealing box, as the lifting screw rotates, the connecting arm will also drive the filter cartridge to rotate away from the sealing box. When the filter cartridge rotates to the top of the receiving box, the lifting screw can be stopped, and finally the sealing bottom plate can be opened so that the suspended matter in the filter cartridge can be discharged downward to the inside of the receiving box for collection.

[0022] 2. It is convenient to clean the inner cavity of the filter cartridge. When the sealing bottom plate is removed, the sealing bottom plate will drive the scraper to move synchronously through the positioning plate. At this time, the scraper can scrape the inner wall of the filter cartridge to prevent impurities and suspended matter from adhering to the inner wall of the filter cartridge. When it needs to be reinstalled, the positioning plate and scraper can be inserted into the inner side of the filter cartridge from the lower end again. When the sealing bottom plate is connected to the filter cartridge, the scraper will be located on the inner wall of the upper end of the filter cartridge, which is convenient for the next removal and scraping, thereby improving the overall cleanliness.
