Embodiment 1

[0044] Embodiment 1 kettle body sealing process

[0045] Refer to attached figure 1 to attach Figure 9 , first, install the sealant strip in the sealing groove (92) of the gland (41); then start the closing operation button of the device, and the control system will automatically work according to the following steps.

[0046] 1) The rotating arm moving device (6) pushes the rotating arm (8) to rotate towards the kettle body (21), and when the gland (41) reaches directly above the kettle body (21), the rotating arm (8) stops moving;

[0047] 2) The cover push-pull device (10) moves downward, and the connecting piece (42) drives the limit guide rod (51) to move downward. When the upper limit plate (56) approaches the upper proximity sensor (55), the cover push-pull device (10 ) stop motion, the gland matching end (91) of the gland (41) cooperates with the mouth of the kettle body (21) to compress, and the gland locking end (93) of the gland (41) and the kettle body (21) The...

Embodiment 2

[0051] Embodiment 2 Kettle body opening process

[0052] Refer to attached figure 1 to attach Figure 9 , First, complete the pressure relief in the kettle; then start the closed operation button of the equipment, and the control system will automatically work according to the following steps.

[0053] 1) The push rod of the clamp lock push-pull device (71) of the clamp lock device (13) moves downward, when the stopper (73) on the push rod of the clamp lock push-pull device (71) and the proximity sensor A (72) When approaching, the locking ears (83) of a pair of clamp A (31) and clamp B (32) are no longer in the locked state, and the clamp locking push-pull device (71) stops moving;

[0054] 2) The clamp opening and closing push-pull device (36) of the clamp opening and closing assembly (5) pulls a pair of clamps to rotate around the column A (3) through the connecting rod (34), and the pair of clamps A (31) and the clamps Hoop B (32) is separated from the fully aligned gla...

Abstract

The invention discloses full-automatic opening and closing vertical supercritical fluid foaming equipment aiming at defects of high labor intensity of workers and low production safety in high-pressure operation of an existing supercritical fluid reaction device. The equipment adopts a hoop type seal mode, namely a lock end of a kettle body and a lock end of a pressure cover are fixedly locked byan annular groove of a hoop. The equipment mainly comprises a supporting frame, a power device, a vertical column A, a vertical column B, a hoop opening-closing component, a rotary arm moving device,a connection supporting plate, a rotary arm, a cover lifting limiting device, a cover push-pull device, a pressure cover component, a hoop component, a hoop locking device and a kettle component. Automatic operations in pressure cover lifting and deflecting and hoop opening, closing and locking are realized, and automatic lifting of the pressure cover and automatic locking and opening of the hoopare realized by cooperation of proximity sensors and limiting plates. Work intensity of operators is automatically relieved, production efficiency is improved, and safety in operation is improved. Theequipment is suitable for high-pressure supercritical processing of materials.

Description

technical field [0001] The invention relates to the field of polymer material processing, mainly relates to supercritical foaming processing of polymer materials, in particular to a fully automatic opening and closing vertical supercritical fluid foaming equipment. Background technique [0002] Batch tank foaming is a commonly used laboratory foaming process for polymer supercritical fluids. Since supercritical foaming needs to be carried out under certain conditions such as temperature and pressure, the sealing of the kettle body and the kettle cover is extremely important for the safety of the equipment and the effect of use. [0003] The utility model patent CN2620578Y discloses a supercritical fluid reactor. In this patent, the reactor adopts six tightening bolts to make the cover press the sealing head to achieve the sealing effect. The sealing method of the invention is easy to operate, but the bolt cooperation operation is cumbersome in the process of opening the cov...
