Embodiment 1

[0028] Embodiment 1 tank body sealing process

[0029] Refer to attached figure 1 to attach Figure 8 , when the tank assembly (1), clamp assembly (2), and compression assembly (3) are in a non-combined state, put the polymer to be processed into the inner cylinder (15), and then pass through the clamp The rotation control assembly (43) in the assembly (2) rotates the clamp (45), and the steps are as follows:

[0030] 1) Rotate the limit handle (64) until the handle is in contact with the limit pin B (78). At this time, the gap of the notch disc (79) of the limit handle (64) is facing the clamp (45), without affecting the clamp (45) turn;

[0031] 2) Turn the gear handle (62) installed on the rotating shaft (63) around the axis A (74), so that the gear handle (62) is turned into the shaft limit groove (76) of the base B (61), at this time The gear of the gear handle (62) meshes with the rotating teeth (86) on the clamp (45), and the rotation of the gear handle (62) can mak...

Embodiment 2

[0036] Embodiment 2 supercritical fluid processing

[0037] Refer to attached figure 1 , attached image 3 , attached Figure 7 And attached Figure 8 , preparatory steps for supercritical fluid processing:

[0038] 1) Heating medium oil injection, emptying and cleaning

[0039] Fill the oil from the heat transfer oil inlet (27) into the hollow space formed by the tank locking end (14), the inner cylinder (15) and the jacket (16), and the excess oil will be discharged from the heat transfer oil outlet (24) Recycling, when the oil contains impurities and needs to be discharged from the tank, the oil can be completely emptied by connecting an external conduit at the drain outlet (26).

[0040] 2) Installation and connection of tank monitoring, safety devices and external media

[0041] Install and connect the safety valve, pressure gauge and temperature sensor at the safety valve interface (21), pressure gauge interface (22) and temperature sensor connecting pipe extension...

Embodiment 3

[0043] Embodiment 3 tank opening process

[0044] Refer to attached figure 2 to attach Figure 8 , the tank opening process steps are:

[0045] 1) Rotate the circular turret (96) to unscrew the T-shaped compression block (93) of the compression assembly (3) from the clamp (45), and then place the compression assembly (3) along the track (4) as a whole Move outward until the tapered guide rod (91) is out of contact with the clip (45);

[0046] 2) Rotate the limit handle (64) until the handle is in contact with the limit pin B (78). At this time, the gap of the notch disc (79) of the limit handle (64) is facing the clamp (45), and the clamp (45) In the unlocked state, then the gear of the gear handle (62) is engaged with the rotating teeth (86) on the clamp (45), and the clamp (45) can be rotated by turning the gear handle (62);

[0047] 3) Rotate the clamp (45) in the opposite direction to make the guide limit groove (85) turn to the position of the notch disc (79) of the ...

Abstract

Aiming at the problems that a conventional supercutical fluid reaction kettle is inconvenient to operate and security protection devices are insufficient, the invention discloses horizontal supercutical fluid foaming equipment which mainly consists of a tank component, a hoop component, a pressing component, a track and a rack, wherein the tank component is horizontally arranged; the whole tank component is sealed in a hooped manner; the hoop component and the pressing component are matched with the track and the rack and are arranged with the tank component in a linear manner; the hoop component and the pressing component are moved in a track direction; and the hoop component is matched with the end part of the tank component through guide of the track; the pressing component is mounted in the hoop component along guide of the track. By adopting the equipment, the track is adopted for horizontal movement matching, a tank is locked by using a dual structure, and the operation of the device is facilitated; and the tank is provided with pressure, temperature and security protection devices and gas recycling device mounting interfaces, and real-time monitoring and security protectionin the processing process can be achieved. The equipment is applicable to supercutical fluid on-batch production processing on polymer granules.

Description

technical field [0001] The invention relates to the field of polymer material processing, mainly relates to supercritical processing of foaming materials, in particular to a horizontal supercritical fluid foaming device. Background technique [0002] Polymer supercritical fluid foaming molding methods mainly include continuous extrusion foaming, injection foaming and batch kettle foaming. Different molding methods have different characteristics. Continuous extrusion molding is suitable for foaming materials with regular cross-sectional shapes. Injection foaming molding can inject foamed products with complex shapes. These two molding processes have high efficiency, but the equipment investment is large and the process It is cumbersome; although batch-type foaming is less efficient than the former two, but the product quality is stable, it is the most widely used in experimental research. Since polymer supercritical foaming requires certain conditions such as temperature and...
