Description

Technical Field

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

[0002] Metal halide scintillating crystals, such as cesium iodide, sodium iodide, lanthanum bromide, strontium iodide, etc., are a very important type of crystals. These crystals will produce a large amount of blocky or granular solid waste due to unqualified quality, fragmentation, head and tail materials, processing scraps, etc. during the production process. Since metal halide raw materials are expensive, these solid wastes have a high recycling value. Because most metal halides have high solubility, and as the temperature increases, the solubility increases significantly, recrystallization is a very suitable recycling method.

[0003] In the conventional recrystallization purification process, the filter paper is easily clogged by suspended matter, precipitate and the purified material precipitated due to the temperature drop during the transfer process, resulting in very slow and inefficient filtration. Even if the filtration is carried out while heating, the filter paper and filter cloth residues can easily enter the feed liquid, resulting in a high carbon content in the final purified product, affecting the purification quality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a recrystallization purification device to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a recrystallization purification device, comprising: a purification tube, a heating jacket, an overflow assembly and a cut-off assembly, wherein the heating jacket is installed on the surface of the purification tube, the overflow assembly is connected to the surface of the purification tube, and the cut-off assembly is arranged at the bottom end of the purification tube;

[0006] The purification tube includes a cylindrical tube, the surface of the top end of the cylindrical tube is integrally connected to a guide tube, the bottom end of the cylindrical tube is integrally connected to a storage bucket, the bottom end of the storage bucket is integrally connected to a discharge pipe, the heating jacket is installed on the surface of the cylindrical tube, and the heating jacket is located below the guide tube, the overflow assembly is arranged at one end of the guide tube, the intercepting assembly is connected to the bottom end of the discharge pipe, the bottom end of the inner wall of the cylindrical tube is connected to an isolation plate, and a plurality of fine holes are provided on the isolation plate.

[0007] Preferably, the overflow assembly comprises an overflow valve and an overflow pipe, the overflow valve is installed at one end of the outlet pipe, and the overflow pipe is installed at the output end of the overflow valve.

[0008] Preferably, the intercepting assembly comprises a rubber tube and a tube clamp, the rubber tube is sleeved on the bottom end of the exhaust tube of the purification tube, and the tube clamp is clamped on the surface of the rubber tube.

[0009] Preferably, the purification tube is made of quartz.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The recrystallization purification device is provided with a heating jacket, a purification tube, an overflow component, an interception component and an isolation plate. The purified material is added to the isolation plate with fine holes, and then deionized water is added under the premise of ensuring that a saturated solution is formed at a high temperature. The water level is higher than the overflow component. The impurity precipitation and the undissolved purified material in the solution will gradually sink and be enriched at the position of the interception component. The suspended matter will be enriched on the liquid surface. The overflow component is opened first to discharge the suspended matter, and then the interception component is opened to discharge the sediment. Impurities can be quickly discharged, and at the same time, it is prevented that filter paper and filter cloth residues are mixed into the purified product, thereby improving the purification quality.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0016] See also Figure 1-2 , a recrystallization purification device, comprising: a purification tube 1, a heating jacket 2, an overflow assembly 3 and a cut-off assembly 4, wherein the heating jacket 2 is installed on the surface of the purification tube 1, the overflow assembly 3 is connected to the surface of the purification tube 1, the cut-off assembly 4 is arranged at the bottom end of the purification tube 1, and the purification tube 1 is made of quartz;

[0017] The purification tube 1 includes a cylindrical tube 101, the surface of the top end of the cylindrical tube 101 is integrally connected with a guide tube 102, the bottom end of the cylindrical tube 101 is integrally connected with a storage bucket 103, the bottom end of the storage bucket 103 is integrally connected with a discharge pipe 104, the heating jacket 2 is installed on the surface of the cylindrical tube 101, and the heating jacket 2 is located below the guide tube 102, the overflow assembly 3 is arranged at one end of the guide tube 102, the intercepting assembly 4 is connected to the bottom end of the discharge pipe 104, and the bottom end of the inner wall of the cylindrical tube 101 is connected with an isolation plate 5, and a plurality of fine holes 6 are opened on the isolation plate 5.

[0018] The overflow assembly 3 includes an overflow valve 301 and an overflow pipe 302 . The overflow valve 301 is installed at one end of the outlet pipe 102 , and the overflow pipe 302 is installed at the output end of the overflow valve 301 .

[0019] The intercepting assembly 4 includes a rubber tube 401 and a tube clamp 402 . The rubber tube 401 is sleeved on the bottom end of the exhaust tube of the purification tube 1 , and the tube clamp 402 is clamped on the surface of the rubber tube 401 .

[0020] When in use, the substance to be purified is added to the isolation plate 5 with fine holes 6, and then deionized water is added under the premise of ensuring that a saturated solution is formed at a high temperature, and the water level is higher than the outlet pipe 102 and the overflow pipe 302, and then the cylindrical tube 101 of the purification tube 1 is heated by the heating jacket 2, and the temperature is controlled within 60-100 degrees, and it is careful not to exceed the boiling point to promote the dissolution of the substance to be purified;

[0021] like Figure 2 After the dissolution is completed, the solution is allowed to stand for 0.5-1 hour. At this time, the impurity precipitation and the undissolved purified material in the solution will gradually sink and accumulate in the storage bucket 103, the discharge pipe 104 and the rubber tube 401, and the suspended matter will accumulate on the liquid surface;

[0022] At this time, open the overflow valve 301 to guide the suspended impurities on the liquid surface out. If the impurities are not completely removed once, you can add deionized water again and remove them multiple times. After the upper suspension is removed, loosen the rubber hose 401 clamp to discharge the impurity precipitation at the bottom through the rubber hose 401. Similarly, you can let it stand for multiple times to remove the impurities and completely remove the precipitation at the bottom. Then close the rubber hose 401 clamp, clean the lower rubber hose 401 with deionized water, and then release the clean and clear solution through the rubber hose 401 clamp to obtain the required hot saturated mother liquor. According to different products, the mother liquor can be filtered while hot or directly cooled to obtain the target product purified by recrystallization.

[0023] This method can remove suspended impurities and precipitated impurities relatively smoothly, avoiding the drawbacks of slow filtration speed and poor efficiency of filter paper and the high carbon impurities that are easily generated, and has high practical value.
