It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a phosphoric acid decolorization device, such as Figures 1-5 As shown, the phosphoric acid decolorization device includes: a decolorization box 1 for decolorizing phosphoric acid; an activated carbon fiber cloth 3 fixedly installed in the decolorization box 1 for decolorizing phosphoric acid; a stirring rack 4 rotatably installed in the decolorization box 1 and located below the activated carbon fiber cloth, the stirring rack 4 being driven to rotate by a stirring mechanism; and a cleaning mechanism assembled on the decolorization box 1 for cleaning the activated carbon fiber cloth 3.

[0022] In this embodiment, a controller, model OMRON E5CC-QX2ASM-800, is first installed on one side of the device. The controller allows for the operation of the entire device. When decolorizing phosphoric acid, the phosphoric acid is placed in the decolorization tank 1. The activated carbon fiber cloth 3, which is fixedly installed, performs the initial adsorption and decolorization of the phosphoric acid. Then, a stirring mechanism drives the stirring rack 4 to rotate, mixing the decolorized phosphoric acid solution with a suitable decolorizing agent, such as hydrogen peroxide. This allows for a second decolorization treatment of the phosphoric acid, effectively improving the decolorization effect. Simultaneously, a cleaning mechanism uses a cleaning agent to clean the activated carbon fiber cloth 3, preventing it from reducing its decolorization effect due to adsorption saturation. Effective cleaning extends the service life of the activated carbon fiber cloth 3, reducing replacement frequency and thus lowering operating costs. The entire device provides a double decolorization treatment for phosphoric acid, resulting in good decolorization and easy cleaning of the activated carbon fiber cloth 3, preventing it from reducing its decolorization effect due to adsorption saturation, extending its service life, reducing replacement frequency, and lowering operating costs.

[0023] In a further preferred embodiment of the present invention, the decolorizing box 1 includes a first processing chamber 101 and a second processing chamber 102 that are connected vertically. The activated carbon fiber cloth 3 is located in the first processing chamber 101, and the stirring rack 4 is located in the second processing chamber 102. The first processing chamber 101 and the second processing chamber are connected by a feeding pipe 16. The feeding pipe 16 is provided with a sealing mechanism for sealing the feeding pipe 16.

[0024] In this embodiment, phosphoric acid is placed in the first processing chamber 101 of the decolorization chamber 1. The phosphoric acid is adsorbed and decolorized by the fixed activated carbon fiber cloth 3. At the same time, the sealing mechanism is opened by the controller or manually to block the feed pipe 16, and the decolorized phosphoric acid in the first processing chamber 101 is put into the second processing chamber 102. Then, the stirring mechanism drives the stirring rack 4 to rotate to mix the decolorized phosphoric acid solution and the corresponding decolorizing agent in the second processing chamber 102, thereby performing a second decolorization treatment on the phosphoric acid, effectively improving the decolorization effect of phosphoric acid.

[0025] In a further preferred embodiment of the present invention, the cleaning mechanism includes: two cleaning pipes 5 rotatably installed on the inner walls of both sides of the decolorizing box 1 and located on the upper and lower sides of the activated carbon fiber cloth, wherein the cleaning pipes 5 are provided with a plurality of nozzles 6 facing the activated carbon fiber cloth; and a connecting pipe 7 fixedly installed on the outer wall of one side of the decolorizing box 1, wherein two flexible hoses 8 are connected to the connecting pipe 7, and the two flexible hoses 8 are respectively connected to the two cleaning pipes 5.

The pressurized cleaning agent flows into the two cleaning pipes 5 through the connecting pipe 7 and the two hoses 8 respectively, and then sprays out from the multiple nozzles 6 on the cleaning pipes 5 to clean both sides of the activated carbon fiber cloth 3. This prevents the activated carbon fiber cloth 3 from reducing its decolorization effect on phosphoric acid due to adsorption saturation, and at the same time extends the service life of the activated carbon fiber cloth 3, reduces the replacement frequency, and thus reduces the cost of use. At the same time, the decolorization box 1 is equipped with two discharge pipes. When cleaning the activated carbon fiber cloth 3, the two discharge pipes are opened to drain the cleaning water. The two discharge pipes are located on the upper and lower sides of the activated carbon fiber cloth 3 respectively.

[0028] In this embodiment, when using the stirring mechanism, the second servo motor 13 is started by the controller to drive the mounting shaft 14 to rotate. The other end of the mounting shaft extends into the fixed frame from the side, and the bottom of the stirring frame extends into the fixed frame from the top. The bottom of the stirring frame is supported and constrained by bearings. The bearings are preferably combined bearings, such as angular contact ball bearings or thrust cylindrical roller bearings + deep groove ball bearings. Since the two bevel gears 15 mesh with each other and bear axial and radial loads, the mounting shaft 14 drives the stirring frame 4 to rotate, mixing the phosphoric acid and decolorizing agent in the second processing chamber 102. The decolorizing chamber 1 is equipped with a heating plate for heating the second processing chamber 102, and the heating plate is equipped with a WEST 6100 temperature controller. The heating plate is used to heat the phosphoric acid and decolorizing agent in the second processing chamber 102, improving the decolorization effect of phosphoric acid.

[0029] In a further preferred embodiment of the present invention, the sealing mechanism includes: a horizontally rotatably mounted placement shaft 18 on the feed pipe 16, a stop block 17 fixedly sleeved on the placement shaft 18, the stop block 17 being adapted to the inner wall of the feed pipe 16; and a third servo motor 19 fixedly mounted on the outer wall of one side of the decolorizing box 1, the output shaft of the third servo motor 19 being fixedly connected to one end of the placement shaft 18.

[0030] In this embodiment, the blocking and opening of the feed pipe 16 can be flexibly controlled by the cooperation of the third servo motor 19, the placement shaft 18 and the stop block 17, thereby controlling the flow of phosphoric acid between the first processing chamber 101 and the second processing chamber 102, which facilitates the adjustment of the processing flow according to actual needs.

[0032] In this embodiment, when phosphoric acid and decolorizing agent are mixed for decolorization, the vent pipe 20 is connected to the corresponding ozone gas pipe, so that ozone can be introduced into the second processing chamber 102 to improve the decolorization effect of phosphoric acid. An exhaust pipe is provided on one side of the decolorization box 1. When ozone is introduced into the second processing chamber 102, the exhaust pipe is opened for certain exhaust treatment according to actual needs.

[0033] In summary, compared with related technologies, the entire device can perform dual decolorization treatment on phosphoric acid, with good decolorization effect and easy cleaning of activated carbon fiber cloth 3, avoiding the reduction of decolorization effect on phosphoric acid due to adsorption saturation. At the same time, it can extend the service life of activated carbon fiber cloth 3, reduce the replacement frequency, and thus reduce the cost of use.
