Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment cleaning, in particular to a ceramic plate pickling device. Background Art
[0002] In the daily operation and maintenance of ceramic filters, the consumption of ceramic plates is the main cost of equipment operation. During the operation of the ceramic filter, the ceramic plates continuously adsorb and dehydrate gold concentrate, and small particles of gold concentrate will slowly and continuously block the permeable micropores of the ceramic plates.
[0003] At present, the cleaning of the waste ceramic plates in the ceramic filter mainly involves disassembling the ceramic plates and placing them in the relevant cleaning device for cleaning. During the cleaning process, the ceramic plates are usually placed under the liquid surface of the acid solution and cleaned with high pressure, which may cause damage to the ceramic plates. Moreover, it is difficult to prevent the gold concentrate that has been cleaned from adhering to the ceramic plates again when the ceramic plates are placed under the liquid surface of the acid solution, resulting in poor cleaning effect. In this case, the ceramic plates need to be replaced after a certain period of operation, and the replaced waste ceramic plates are scrapped.
[0004] In order to achieve a better cleaning effect, in the prior art, based on the above structure, there are also some solutions that introduce ultrasonic cleaning equipment and use low-concentration acid to clean the ceramic plate. Although ultrasonic cleaning has certain beneficial effects on ceramic plate cleaning, the low-concentration acid has a poor cleaning effect on the ceramic plate, and the ceramic plate is still placed below the liquid surface of the acid during the cleaning process. It cannot be avoided that the gold concentrate that has been cleaned will adhere to the ceramic plate again, and the introduction of ultrasonic cleaning equipment will also increase costs.

[0015] like Figures 1-2 As shown, the ceramic plate pickling device involved in the present application includes a stainless steel acid tank 1 for holding acid, and the stainless steel acid tank 1 is provided with an acid collection port 2. When the ceramic plate pickling device is not used for a long time or needs to be discharged, the acid collection port 2 is used to connect to relevant equipment to collect the acid in the stainless steel acid tank 1, saving the operating cost of the equipment. A sewage outlet 3 is provided at the bottom plate of the stainless steel acid tank 1 to discharge the washed gold concentrate. In order to facilitate the movement of the ceramic plate pickling device, a plurality of universal wheels 4 with brakes are also provided on the stainless steel acid tank 1.
[0016] An acid-resistant pump 6 for conveying acid is connected to the stainless steel acid tank 1 via a liquid inlet pipe 5 (e.g., a polytetrafluoroethylene tube). The liquid inlet pipe 5 is located at a preset height from the bottom plate of the stainless steel acid tank 1 to further prevent the cleaned gold concentrate from being sprayed into the ceramic plate 11 again via the acid-resistant pump 6.
[0017] The liquid outlet of the acid-resistant pump 6 is connected to the stainless steel pickling pipe 7, and the stainless steel pickling pipe 7 extends to the interior of the stainless steel acid liquid tank 1. The end of the stainless steel pickling pipe 7 in the stainless steel acid liquid tank 1 is closed. The stainless steel pickling pipe 7 can be connected to the bottom plate of the stainless steel acid liquid tank 1 through a support column, or the end of the stainless steel pickling pipe 7 is sealed and connected to the inner wall of the stainless steel acid liquid tank 1. The liquid level of the acid in the stainless steel acid liquid tank 1 is lower than the stainless steel pickling pipe 7. A plurality of stainless steel nozzles 8 are provided on the stainless steel pickling pipe 7 at intervals along the long direction of the stainless steel pickling pipe 7. Each stainless steel nozzle 8 is connected to the stainless steel pickling pipe 7, so that the acid pumped out from the acid-resistant pump 6 can be discharged from each The stainless steel nozzle 8 sprays out; each stainless steel nozzle 8 is connected with an acid-resistant rubber tube 9, and the acid-resistant rubber tube 9 is also used to connect with the connecting part 1101 of the ceramic plate 11. The stainless steel nozzle 8 can be connected to the ceramic plate 11 through the acid-resistant rubber tube 9, and this assembly method is simpler and faster; two stainless steel supports 10 used in conjunction with each other, such as stainless steel support tubes, are arranged at intervals at the upper end opening of the stainless steel acid liquid tank 1. The stainless steel support 10 is used to support the ceramic plate 11, and the two side surfaces of the ceramic plate 11 are respectively abutted against the corresponding stainless steel supports 10. Through the cooperation of the two stainless steel supports 10 and the acid-resistant rubber tube 9, the ceramic plate 11 can be firmly positioned on the ceramic plate pickling device.
[0018] In this embodiment, the stainless steel acid tank 1, the stainless steel pickling pipe 7, the stainless steel nozzle 8 and the stainless steel support 10 are all made of 304 stainless steel. The acid-resistant pump 6 is a Korean Chisei AX1-32 metering pump.
[0019] In the specific use process, the prepared 50% concentration oxalic acid solution is poured into the stainless steel acid tank 1, and the liquid level of the acid is ensured to be lower than the stainless steel pickling pipe 7, and the connecting part 1101 of the ceramic plate 11 to be cleaned is connected to the corresponding acid-resistant rubber tube 9, and the ceramic plate 11 is firmly positioned on the ceramic plate pickling device through the cooperation of the two stainless steel supports 10 and the acid-resistant rubber tube 9. The acid is sucked into the acid-resistant pump 6 through the liquid inlet pipe 5, and then pumped into the stainless steel pickling pipe 7, and then the acid is sprayed out from each stainless steel nozzle 8, and finally the acid enters the interior of the ceramic plate 11, and the interior of the ceramic plate 11 is pickled continuously until the pickling reaches the effect equivalent to that of a new ceramic plate.
[0020] The ceramic plate pickling device involved in the present application is used to clean the ceramic plates in the ceramic filter. Since the liquid level of the acid solution is always below the stainless steel pickling tube 7, the ceramic plates will not be immersed in the acid solution, which can avoid the gold concentrate washed out from being sucked into the ceramic plates again as much as possible, and has the advantage of good cleaning effect. In addition, since the liquid level of the acid solution is always below the stainless steel pickling tube 7, the ceramic plates can be cleaned with low-flow, low-pressure, and high-concentration acid solution to reduce the impact damage to the ceramic plates and improve the cleaning effect.
[0021] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto.
