Combined sealing device

Номер: CN116480780A
Автор: ZHANG XINHENG, XU ZUJIN, LIU YONGSHENG, WANG BO
Принадлежит:

The invention relates to a combined sealing device which comprises a sealing seat and a sealing piece, the sealing seat is provided with a sealing cavity for a rotating shaft to penetrate through, the sealing piece is detachably connected to the inner wall of the sealing cavity, and the sealing piece is used for abutting against the outer wall of the rotating shaft to form sealing; when the rotating shaft penetrates through the sealing cavity, the sealing seat limits the sealing piece on the outer wall of the rotating shaft, and the sealing piece abuts against the outer wall of the rotating shaft to form sealing. According to the combined sealing device, due to the arrangement of the sealing seat and the sealing piece, the whole combined sealing device does not need to be replaced, material waste is reduced, the concept of energy conservation is embodied, and therefore the use cost of the combined sealing device is reduced; a guide surface is arranged, so that the pre-tightening force between ...

Low-temperature freeze drying system

Номер: CN116608649A
Автор: LIU YONGSHENG, XU ZUJIN, WANG BO, XU PENGYE
Принадлежит:

The low-temperature freeze-drying system comprises a material chamber, a freezing assembly and a cooling assembly, the material chamber is provided with a plurality of material trays, the freezing assembly comprises a plurality of freezing pipelines and a vacuum pump, and the freezing pipelines correspond to the material trays one to one; and an air exhaust pipeline is connected between the plurality of freezing pipelines and the vacuum pump. The freezing pipeline and the vacuum pump are arranged, so that water in the freezing pipeline is recycled, a user does not need to supply water to the low-temperature freeze-drying system all the time, waste of materials is reduced, the concept of energy conservation is embodied, and the use cost of the user on the low-temperature freeze-drying system is reduced; through the arrangement of the drying assembly, ice in the materials absorbs heat and sublimates to form water vapor, drying of the materials is achieved, and therefore the storage time of ...

Variable-section variable-lead vacuum pump

Номер: CN116608125A
Автор: LIU YONGSHENG, XU ZUJIN, WANG BO, XU PENGYE
Принадлежит:

The vacuum pump comprises a screw rod, the screw rod comprises a stud, a front spiral section and a rear spiral section, the front spiral section comprises a plurality of spiral teeth, the rear spiral section comprises a spiral tooth, and the spiral tooth is fixedly connected to the outer wall of the stud; the tooth width of the spiral teeth of the front spiral section is larger than the minimum tooth width of the spiral teeth of the rear spiral section. According to the screw vacuum pump, the tooth width of the rear spiral teeth is increased, the sealing effect between the screw and the inner wall of the pump body is improved through wide tooth top sealing, the compression ratio of the screw vacuum pump is increased, the probability of gas and dust backflow is effectively reduced through the widened tooth width of the spiral teeth, the air exhaust efficiency is improved, and energy consumption is reduced.
