Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A high-efficiency and energy-saving coal-to-oxalic acid crystallizer comprises a support 1, a crystallizer body 3 and a screener 4. Two groups of connecting frames 2 are arranged on the inner side of the support 1, a crystallizer body 3 is arranged on the inner side of the connecting frame 2, a screener 4 is arranged inside the crystallizer body 3, a transmission roller 5 is arranged inside the screener 4, a plurality of groups of mixing rods 6 are arranged equidistantly around the outer side of the transmission roller 5, a driving motor 7 is arranged at the bottom of the crystallizer body 3, a discharge pipe 8 is arranged on the left side of the bottom of the crystallizer body 3, and a control valve 9 is arranged at the output end of the discharge pipe 8.

[0022] Two groups of mounting holes are provided on both sides of the bottom of the bracket 1.

[0023] The connecting end of the connecting frame 2 and the bracket 1 is provided with a mounting groove.

[0024] The outer shell of the crystallizer body 3 is made of transparent material.

[0025] A plurality of through holes are arranged around the outer side of the sieve 4 .

[0026] The front side of the mixing rod 6 is provided with a plurality of through holes, and the through holes are inclined at 15 degrees.

[0027] The output end of the driving motor 7 extends to the crystallizer body 3 and is connected to the driving roller 5 inside the screen 4 .

[0028] Working principle: First, the bracket 1 serves as the supporting structure of the entire crystallizer. Through the two groups of mounting holes set on both sides of its bottom, the crystallizer can be stably fixed on the work platform. At the same time, the connecting frame 2 on the inner side of the bracket 1 has a mounting groove at its connecting end, which is convenient for firm connection with the bracket and further supports the crystallizer body 3. The crystallizer body 3 is the core component of the entire crystallization process. Its outer shell is made of transparent material, so that the operator can intuitively observe the material state during the crystallization process and adjust the operating parameters in time. Inside the crystallizer body 3, the sifter 4 plays a key role. A plurality of through holes are arranged around the outside of the sifter 4. The design of these through holes allows smaller particles and liquids to pass through and be discharged, while larger particles will still be stored in the sifter 4 to facilitate the subsequent classification and collection work of the staff. A plurality of mixing rods 6 are equidistantly arranged around the outside of the transmission roller 5. These mixing rods The mixing rod 6 rotates under the drive of the transmission roller 5 to fully stir and mix the materials in the crystallizer. A plurality of through holes inclined at 15° are provided on the front of the mixing rod 6. This special design not only significantly enhances the mixing effect, but also enables the materials to be more evenly distributed during the stirring process. When the driving motor 7 is started, the transmission roller 5 is driven to rotate through the transmission mechanism, thereby driving the mixing rod 6 to perform circular motion in the crystallizer body 3. During this process, the mixing rod 6 continuously stirs the materials, effectively promoting the mutual collision and combination of oxalic acid molecules, thereby accelerating the crystallization process. Finally, when the crystallization is completed, the operator can open the control valve 9 on the discharge pipe 8 to smoothly discharge the crystallized fine oxalic acid crystal particles and the remaining liquid from the bottom of the crystallizer body 3. The entire crystallization process is carried out in a closed environment, which not only significantly improves the production efficiency, but also effectively reduces the waste of materials and the pollution to the environment.
