Technical Field

[0001] The utility model relates to the technical field of potassium permanganate production equipment, in particular to an explosion-proof potassium permanganate preparation device. Background Art

[0002] The preparation of potassium permanganate mainly requires three raw materials: potassium hydroxide, manganese dioxide and oxygen; dissolve potassium hydroxide in water to form a potassium hydroxide solution, mix manganese dioxide with the potassium hydroxide solution and stir evenly; during the stirring process, introduce oxygen to cause manganese dioxide to react with potassium hydroxide in the presence of oxygen, and during the reaction process, potassium manganate (K2MnO4) and oxygen will be generated; filter the generated potassium manganate solution to remove impurities; acidify the filtered potassium manganate solution to convert it into potassium permanganate; finally, perform steps such as crystallization, separation, and drying on the potassium permanganate to obtain the final product. As a strong oxidant, there are potential explosion risks during the production and use of potassium permanganate.

[0003] In the prior art, the preparation of potassium permanganate requires multiple steps. The integration degree in traditional preparation equipment is relatively low, and the processes of potassium manganate preparation and acidification are not combined, resulting in more transfer processes. This not only easily causes secondary pollution during the turnover process, but also affects the processing efficiency and increases the production cost. Therefore, we propose an explosion-proof potassium permanganate preparation device to solve the above problems. Summary of the Utility Model

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figures 1-3 , an explosion-proof potassium permanganate preparation device, comprising a machine platform 1, a tank body 2 is arranged on the machine platform 1, a feed pipe 3 and a discharge pipe 4 are arranged on the tank body 2, and a preparation component is arranged in the tank body 2;

[0022] The preparation assembly includes a partition plate 5 fixedly connected to the inner wall of the tank body 2, a feed pipe 6 is provided on the lower surface of the partition plate 5, and a filtering structure is provided on the upper end of the feed pipe 6, a stop valve 7 is provided near the filtering structure of the feed pipe 6, a stirring assembly is provided on the upper end of the tank body 2, and an acidification assembly is provided on the lower end of the tank body 2, wherein the acidification assembly can adopt existing acidification processing equipment;

[0023] In this design, the partition plate 5 divides the tank body 2 into two upper and lower areas, respectively carrying out the processes of preparing potassium manganate and acidifying the potassium manganate solution, and the filtering structure is used to filter the impurities generated during the preparation of potassium manganate. The stop valve 7 is used to open the gate after the preparation of the potassium manganate solution is completed to allow the potassium manganate solution to enter the acidification area below the partition plate 5 through the clinker pipe for acidification operation.

[0024] Further, the stirring assembly includes a vertical pipe 8, the lower end side wall of the vertical pipe 8 is connected to a connecting pipe 9, the side wall of the connecting pipe 9 is provided with an air outlet 10, the upper end of the vertical pipe 8 passes through the upper end inner wall of the tank body 2 and is rotatably connected to the tank body 2, the upper end of the vertical pipe 8 is provided with a rotary joint 11, the upper panel of the tank body 2 is fixedly connected to a driving motor 12, and the driving motor 12 provides a gear transmission connection with the vertical pipe 8;

[0025] In this design, the upper end of the vertical pipe 8 is connected to the oxygen tank or oxygen preparation equipment through a rotating joint 11, and the driving motor 12 can drive the vertical pipe 8 to rotate, and the vertical pipe 8 drives the connecting pipe 9 to rotate in the tank body 2, wherein the connecting pipe 9 is not only used to transport oxygen to participate in the preparation of potassium manganate, but also serves as a stirring rod to stir the mixed solution, and when oxygen is discharged from the air outlet 10, it has a better contact effect with the mixed solution, and at the same time, it can also use oxygen to drive the mixed solution to flow, and can also improve the stirring effect of the mixed solution.

[0026] Furthermore, the filtering structure includes a sink 13 provided on the partition plate 5. A filter element 14 is placed in the sink 13. The filter element 14 is arranged above the stop valve 7, and an arc-shaped rod is provided on the filter element 14.

[0027] In this design, the filter element 14 is placed in the sink 13. When the stop valve 7 is closed, the mixed solution cannot pass through the filter element 14. After the potassium manganate solution is prepared and the stop valve 7 is opened, the potassium manganate solution passes through the filter element 14 and flows downward along the feed pipe 6 into the lower end of the tank body 2 for the acidification process. After a single processing is completed, the stop valve 7 is closed, and the processing of potassium manganate is carried out above the filter element 14 again. The arc-shaped rod provided on the filter element 14 is used to take out and replace the filter with a hook when the passability of the filter element 14 is poor, which is convenient for users.

[0028] Furthermore, a diversion platform 15 is provided on the partition plate 5. The diversion platform 15 is provided to ensure that after the potassium manganate solution is prepared, all the potassium manganate solution above the partition plate 5 can flow downward into the acidification assembly.

[0029] Furthermore, the feed pipe 6 is S-shaped, and a plurality of shunt pipes 16 are connected to the lower end of the feed pipe 6. The S-shaped feed pipe 6 can avoid the situation of too large impact force when the potassium manganate solution flows downward. At the same time, even if some impurities pass through the filter element 14, they will accumulate at the bend of the feed pipe 6 to ensure the purity of potassium permanganate after acidification production.

[0030] Furthermore, the connecting pipe 9 is L-shaped, and a conical sleeve 17 is provided at the lower end of the connecting pipe 9. The L-shaped connecting pipe 9 can cover more areas inside the tank body 2. The conical sleeve 17 is provided for two purposes. On the one hand, it is used to ensure that oxygen flows out from a plurality of air outlets 10 and the lower end opening of the conical sleeve 17 when passing through the connecting pipe 9 to ensure the coverage area of oxygen. On the other hand, when the oxygen supply stops, the potassium manganate solution will flow back into the connecting pipe 9, and after the stop valve 7 is opened, the potassium manganate solution in the connecting pipe 9 will also be discharged from the lower end of the conical sleeve 17 to avoid remaining in the connecting pipe 9.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
