Description
Technical Field
[0001] The utility model belongs to the technical field of crystal drying, and particularly relates to a crystal drying device for the production of fluorescent whitening agents. Background Art
[0002] Crystals for the production of fluorescent whitening agents usually refer to raw material crystals used for the production of fluorescent whitening agents. After a series of chemical reactions and treatments, these crystals can be converted into compounds with fluorescent whitening effects. In the production of fluorescent whitening agents, factors such as the purity, particle size, and crystallinity of the crystals may affect the quality and performance of the final product. Therefore, the selection and treatment of crystals usually need to be strictly controlled to ensure the production of high-quality fluorescent whitening agents.
[0003] However, when an existing crystal drying device for the production of fluorescent whitening agents is in use, it is not convenient for classified collection. Since there is no screening, the dried crystals may be uneven in size. This may result in inconsistent whitening effects of crystals of different sizes during subsequent use, thereby affecting the quality stability of the final product. It is possible to accurately screen the crystals according to their sizes to ensure the consistency of the product particle size. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a crystal drying device for the production of fluorescent whitening agents. By setting a screening and collection mechanism, the problem that the dried crystals may be uneven in size due to the lack of screening is solved. This may result in inconsistent whitening effects of crystals of different sizes during subsequent use, thereby affecting the quality stability of the final product.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0042] A specific application of this embodiment is as follows: When in use, first place the first fixing block 1 in a suitable position through the supporting block 101 and the bottom plate 102. Pour the material through the feeding funnel 212, and then start the first motor 222, which will drive the first rotating shaft 214 to rotate. The third rotating shaft 223 is driven to rotate together through the pulleys sleeved on the first rotating shaft 214 and the third rotating shaft 223. Since the first bevel gear 215 and the second bevel gear 219 are engaged, the rotation of the first rotating shaft 214 will cause the fan 218 to rotate, achieving the effect of dust removal and air supply, and making the drying heat more uniform. The rotation of the third rotating shaft 223 will cause the conveyor belt 226 to rotate. A heating pipe 213 is arranged above the conveyor belt 226, and drying is completed during the feeding process and sent to the sieve plate 317. Start the second motor 312, and the eccentric wheel 314 is rotated through the fourth rotating shaft 313. Since the eccentric wheel 314 is hinged to the first connecting block 315, and the first connecting block 315 is hinged to the second connecting block 316, the vibration effect of the sieve plate 317 can be realized under the combined action of the damper 318 and the spring 319. Limited by the third chute 326 and the slider 327, the sieve plate can only move up and down. After screening, small particles will fall into the second collection box 325 below the sieve plate 317, and large particles will fall into the first collection box 323. Since the first chute 322 and the second chute 324 are opened on the outer shell 321 of the collection box, the second collection box 325 and the first collection box 323 can be drawn out for convenient collection. After use, it is convenient to clean, and the collection component can be easily taken out to thoroughly clean the accumulated dust, impurities and residual crystals inside, avoiding blockage and pollution, maintaining a good collection effect, facilitating inspection of whether there are damaged or worn parts in the collection component, and timely repairing or replacing them to extend its service life.
