Description

Technical Field

[0001] The utility model relates to the technical field of vacuum dryers, and more particularly to a circular static vacuum dryer. Background Art

[0002] Under the current technological background, the bidirectional flowability of circular static vacuum dryers during exhaust poses certain safety risks. When exhausting, the airflow of this dryer can flow in two directions. Although this design can increase operational flexibility, it also increases the risk of system leakage. This bidirectional flow characteristic may cause pressure instability during operation of the vacuum dryer, thereby affecting the safety performance and service life of the equipment.

[0003] Furthermore, since existing circular static vacuum dryers allow bidirectional flow during exhaust, this undoubtedly increases the difficulty of sealing the interior of the dryer. Under the action of the bidirectional airflow, the seals of the dryer may be subjected to uneven pressure, resulting in a decrease in sealing performance and even leakage. Once a leakage occurs, it will not only affect the drying efficiency, but may also cause material contamination and, in severe cases, may even lead to safety accidents. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a circular static vacuum dryer with the following beneficial effects:

[0017] 1. The design of the one-way mechanism effectively solves the leakage risk problem caused by the bidirectional flow during exhaust in existing circular static vacuum dryers. Through the cooperation of the one-way pipe and the external pipe, one-way control of the airflow is achieved, reducing the instability of the internal pressure of the system, thereby significantly improving the safety of the equipment. The combination of the sealing disk and the bottom disk, as well as the arrangement of the compression spring and the thrust bearing, ensure the reliability of the seal under vacuum conditions.

In the intermediate tube 10, a compression spring 12 is provided on the lower end surface of the intermediate tube 10, and a thrust bearing 13 is provided on the compression spring 12. The thrust bearing 13 is sleeved on the push rod 11, and the thrust bearing 13 abuts against the sealing disk 5. A plurality of guide rods 14 are slidably provided on the threaded sleeve 8, and a telescopic disk 15 is provided on the plurality of guide rods 14.

[0030] In this embodiment, when a vacuum operation is required, the drying shell 1 needs to be sucked in by an external suction device. First, the external pipe 4 is connected to the suction device, and then the suction will untie the connection between the sealing ring 9 and the bottom plate 6, and then the air in the drying shell 1 is sucked out, thereby ensuring the drying process. When the drying is completed, since the drying shell 1 is under negative pressure, the external pressure will be pressed on the sealing plate 5, and then the pressure between the sealing ring 9 and the resistance plate is used to ensure the sealing state. When the external pipe 4 needs to be completely sealed, by rotating the rotating plate 7, the threaded sleeve 8 is threadedly connected to the one-way On the tube 3, the groove 20 on the fitting sleeve 18 will be stuck on the boss 19, so the external tube 4 will be sealed, thereby ensuring the sealing process.

When pressure relief is needed, you only need to pull the handle to release the seal between the sealing disk 5 and the bottom disk 6, thereby completing the pressure relief process.

[0031] More specifically, when feeding is required, the materials are fed through the first feeding port 22 and the second feeding port 23 respectively, and when drying is completed, the materials can be discharged through the bottom port, thereby completing the vacuum drying process.

[0032] In summary, when the whole equipment is in use or running: when vacuum operation is required, the drying shell 1 needs to be sucked in by an external suction device. First, the external pipe 4 is connected to the suction device, and then the suction will untie the connection between the sealing ring 9 and the bottom plate 6, and then the air in the drying shell 1 is sucked out, thereby ensuring the drying process. When the drying is completed, since the drying shell 1 is under negative pressure, the external pressure will be pressed on the sealing plate 5, and then the pressure between the sealing ring 9 and the resistance plate is used to ensure the sealing state. When the external pipe 4 needs to be completely closed, by rotating the rotating disk 7, the threaded sleeve 8 is threaded. It is connected to the one-way tube 3, and then the groove 20 on the fitting sleeve 18 will be stuck on the boss 19, so the external tube 4 will be sealed, thereby ensuring the sealing process. At this time, the guide rod 14 and the threaded sleeve 8 are not connected, so they will be adjusted separately. When it is necessary to seal and change the pressure of the push spring, the clamping groove 17 will be connected to the clamping block 16. When the rotating disk 7 is rotated, the compression spring 12 will be driven to move together. At this time, it can not only play a sealing role but also increase the sealing force of the sealing disk 5, thereby completing the use process. When pressure relief is needed, you only need to pull the handle to release the seal between the sealing disk 5 and the bottom disk 6, thereby completing the pressure relief process.

[0033] When feeding is required, the materials are fed through the first feeding port 22 and the second feeding port 23 respectively. When drying is completed, the materials can be discharged through the bottom port, thereby completing the vacuum drying process.
