Description

Technical Field

[0001] The utility model relates to the technical field of laboratory dryers, and more specifically, to a laboratory dryer. Background Art

[0002] A laboratory dryer is a device used to remove moisture from the surface or inside of an object. In a laboratory, it is usually necessary to dry experimental samples, reagents or equipment to ensure the accuracy and stability of the experiment. A laboratory dryer is a common glass instrument in a chemical laboratory. When drying, the material is placed on a partition and the desiccant is placed at the bottom of the partition.

[0003] Publication number CN213901713U discloses a laboratory dryer. The laboratory dryers commonly used in laboratories currently have only one partition porcelain plate inside. When in use, the items to be dried are placed above the partition porcelain plate. When there are many types of samples to be dried, it is not easy to classify and place the samples. The storage cavity is divided into multiple sample chambers by multiple partitions. By placing different types of samples in different sample chambers, the samples can be classified and placed. The partitions are made of ceramics, so that the partitions are resistant to high temperature and corrosion, and have stable properties and do not react with chemicals, thereby providing effective support and protection for the drying of items.

[0004] During use, the laboratory dryer only dries the materials placed therein through the desiccant at the bottom of the partition. The drying process takes a long time and has low drying efficiency. At the same time, after the desiccant becomes ineffective, the partition needs to be opened and the desiccant needs to be taken out, and the replacement of the desiccant is relatively troublesome.

[0014] Technical effects and advantages of the utility model:

[0015] By setting a circulating drying mechanism, the air inside the drying vessel body is continuously circulated, so that the hot air flow takes away the moisture on the material to be dried, so that the material contacts the desiccant inside the desiccant placement tank, and circulates quickly for drying. At the same time, the desiccant placement tank can be disassembled, which is convenient for replacing the desiccant inside the desiccant placement tank. Compared with the prior art, the hot air is continuously circulated to take away the moisture, and at the same time, the desiccant continuously absorbs the moisture for drying, which improves the drying efficiency and moisture absorption efficiency of the desiccant, thereby improving the drying efficiency of the overall dryer. At the same time, the desiccant placement tank can be quickly disassembled, which is convenient for quickly replacing the desiccant that has failed inside.

[0016] A first connecting plate is arranged on the top of the desiccant placement tank, and a second connecting plate is arranged on the outer bottom of the connecting pipe. After the first threaded connecting pipe forms a threaded connection with the connecting pipe, the sealing rubber ring in the middle is squeezed by the first connecting plate and the second connecting plate, so that the sealing effect between the connecting pipe and the first threaded connecting pipe is improved by the sealing rubber ring, thereby avoiding leakage of hot air flow.
