Detailed Description of the Preferred Embodiments

[0030] At the center of the bottom of the connection chamber 3, a transverse groove 14 is opened. At the center of the inside of the transverse groove 14, a swing rod 6 is arranged. The top end of the swing rod 6 is rotatably connected to the inner wall of the connection chamber 3, and the bottom end is detachably connected to a connecting rod 2.

[0032] This solution has the following working process:

[0033] During the sulfuric acid purification process, this device effectively solves the problem of uneven heating of sulfuric acid in traditional purification devices through its special design. First, pour the sulfuric acid to be purified into the flask 7. The flask 7 is connected to the swing rod 6 through the connecting rod 2. This design enables the flask 7 to not only be stably suspended below the connection chamber 3 but also be able to swing, thereby increasing the fluidity of the sulfuric acid liquid and achieving more uniform heating. Next, light the heater 8, which is located at the center of the bottom plate 1, to provide a stable heat source for the purification process. As the heater 8 heats up, the sulfuric acid in the flask 7 begins to be heated. At this time, the adjusting screw 5 comes into play. By rotating the adjusting screw 5, the degree of pressure of the contact member on the swing rod 6 can be changed, thereby controlling the swing amplitude and frequency of the flask 7. This swing makes the sulfuric acid in the flask 7 flow continuously, ensuring that all parts are evenly heated and improving the purification efficiency.

[0034] According to the above working process, it can be known that:

[0035] This sulfuric acid purification device, through innovative design, significantly solves the technical problem of uneven heating of sulfuric acid in traditional purification devices during the heating process. Its main advantages are as follows: Through the design of the swing rod 6 and the connecting rod 2, the controllable swing of the flask 7 is realized, ensuring that the sulfuric acid can be continuously mixed during the heating process, avoiding local overheating or unheated situations, and thus significantly improving the speed and efficiency of sulfuric acid purification. The introduction of the adjusting screw 5 enables the operator to flexibly adjust the swing amplitude of the flask 7 according to actual needs, which not only ensures the uniformity of heating but also avoids heat loss or safety hazards caused by excessive swing. The whole device has a compact structure and is easy to operate, which not only improves the safety and controllability of the purification process but also reduces the operation difficulty and is conducive to large-scale industrial application. In summary, this device shows significant advantages in improving the sulfuric acid purification efficiency, ensuring operation safety, and enhancing process flexibility, and has important practical value for the production of high-purity sulfuric acid in the metallurgical and petroleum industries.

[0036] Furthermore, the contact member includes a mounting seat 13 rotatably connected to one end of the adjusting screw 5, and a rotating wheel 12 is rotatably connected inside the mounting seat 13.

[0037] Furthermore, a counterweight is connected to the bottom of the mounting seat 13, and a grip is connected to one end of the adjusting screw 5.

[0038] Furthermore, a mounting frame 15 is fixedly connected to the bottom end of the swing rod 6, a driving motor 16 is installed inside the mounting frame 15, and the output shaft of the driving motor 16 passes through the mounting frame 15 through a bushing and is connected to a hexagonal plug 17.

[0041] Workflow:

[0042] During the working process of the sulfuric acid purification device, each component works together to ensure the efficiency and safety of purification. First, the operator pours sulfuric acid into the flask 7. The flask 7 is stably connected to the swing rod 6 through the connecting rod 2, ensuring that the flask 7 can swing freely, enhancing the fluidity of the sulfuric acid solution to achieve uniform heating. The heater 8 is located at the center of the bottom plate 1, providing a stable heat source for the purification process. When the heater 8 is ignited, the sulfuric acid in the flask 7 begins to be heated.

[0043] At this time, the adjusting screw 5 plays a key role. The operator can rotate the adjusting screw 5 to change the degree of compression of the contact member, that is, the mounting seat 13 and the rotating wheel 12, on the swing rod 6. This design cleverly controls the swing amplitude and frequency of the flask 7, ensuring that the sulfuric acid flows continuously during the heating process and is evenly heated in each part, thereby improving the purification efficiency.

The entire device has a compact structure and is easy to operate, not only improving the safety and controllability of the purification process, but also reducing the operation difficulty.

[0046] Beneficial effects:

[0047] First of all, through the design of the swing rod 6 and the connecting rod 2, the controllable swing of the flask 7 is realized, ensuring the continuous mixing of sulfuric acid during heating, avoiding local overheating or non-heating conditions, and thus greatly improving the speed and efficiency of sulfuric acid purification. Secondly, the introduction of the adjusting screw 5 and the contact part enables the operator to flexibly adjust the swing amplitude of the flask 7 according to needs, ensuring both the uniformity of heating and avoiding heat loss or safety hazards that may be caused by excessive swing.

[0048] In addition, the design of the drive motor 16 and the hexagonal plug 17 inside the mounting frame 15 not only enhances the connection stability, but also greatly simplifies the replacement or maintenance process. The detachable connection between the mounting plate 10 and the mounting frame 15, as well as the ingenious cooperation between the positioning screw 9 and the screw hole, further improves the flexibility and convenience of the device.
