A rotary vacuum sealing system

Abstract

The invention discloses a rotation type vacuum sealing system comprising a support frame, an air control device, sealing devices, a rotating device, and an annular sealing-connecting device; the support frame comprises a support plate and support rods; the air control device comprises a main pipeline, a vacuum-pimping mechanism and an inflating mechanism; each sealing device comprises a sealing mechanism, a rotating mechanism, a driving mechanism, and a control valve; the rotating device comprises a hollow shaft, a shaft sleeve, driving wheels, and magnetic fluid sealing elements, the lower end of the hollow shaft is connected with the control mechanism, the upper end of the hollow shaft is connected with the shaft sleeve, and the upper end of the shaft sleeve communicates with the main pipeline through the control valve; and the annular sealing-connecting device comprises an annular heater, an oxyhydrogen machine, a gas pipeline, and a heating holder. According to the rotation type vacuum sealing system, multiple sealing devices are arranged on the support plate, and the synchronous sealing of multiple test tubes is realized through the rotating mechanism to facilitate to enhancesealing efficiency is enhanced; and the test tubes can be rotated in a vacuum through the rotating mechanism, an annular heater and the test tubes are cooperatively used for heating to avoid manual control, and the balance and security of heating sealing is enhanced to facilitate synchronous sealing of the multiple test tubes.

Description

technical field [0001] The invention relates to vacuum sealing technology, in particular to a rotary vacuum sealing system. Background technique [0002] At present, most of the traditional vacuum sealing devices are temporary constructions. Generally, bottled storage gas such as acetylene is used to provide fuel, and the test tube is evacuated by a vacuum pump at high temperature, and then the test tube is stretched and contracted. Because the existing vacuum sealing devices are mostly controlled by human operation, their automation degree is low, and the operator's experience requirements are high, especially when sealing, it needs to control the continuous rotation of the test tube under vacuum conditions to ensure the uniformity of high temperature heating, In order to ensure that the test tube is stretched and contracted, the operation is difficult and the failure rate is high, which is not conducive to the efficient and safe packaging of samples.
