Description

Technical Field

[0001] The utility model relates to the technical field of crystallization purification, in particular to a crystallization purification device. Background Art

[0002] Crystallization purification is a commonly used chemical separation technology, widely used in chemistry, biology, medicine and other fields. Its core principle is based on the difference in solubility of different substances in the same solvent. Through dissolution, crystallization, filtration and other steps, the target substance in the mixture is separated to achieve the purpose of purification.

[0003] The existing crystallization purification device is not convenient for cleaning the filter device. Long-term operation can easily cause the surface of the filter device to be blocked by impurities, thereby affecting the filtering effect. At the same time, the filter used to filter impurities is usually installed inside the device, so it is very inconvenient to clean the filter. Based on these problems, Chinese patent CN217794616U discloses a mixed salt crystallization purification device, which is provided with a dissolution box, an injection port, a filter box, a crystallization box, a transmission pipe, a control valve, a filter net, a forward and reverse motor, a threaded rod, a threaded slider, a fixed rod, a cleaning brush, an opening, a bearing plate, a box door, a heating plate and an exhaust pipe. The threaded rod can be rotated under the drive of the forward and reverse motors, so that the threaded slider drives the fixed rod and the cleaning brush to move horizontally on the surface of the filter net, so that the impurities remaining on the surface of the filter net can be cleaned out. The surface is accumulated for a long time and blocks the filter net, thereby affecting the filtering effect of the filter net.

[0004] First of all, the threaded rod in the device is arranged inside the filter box, so part of the mixed liquid flowing down from above will slide over the surface of the threaded rod. When there is too much mixed liquid above the filter screen, the threaded rod will be immersed in the mixed liquid. At this time, some impurities in the mixed liquid will adhere to the threaded groove on the surface of the threaded rod. If it is not removed in time, it will not only make the threaded slider difficult to slide, but also affect the cleaning effect of residual impurities on the surface of the filter screen. Secondly, the crystallization box in the device is only equipped with one set of exhaust pipes. In order to balance the air pressure inside and outside the crystallization box, the external gas will also enter the crystallization box from the exhaust pipe with dust, thus affecting the purity of the crystallization.
