Four-block combination two-way opening and closing clamp horizontal type supercritical fluid foaming quick-opening device

Abstract

The invention provides a four-block combination two-way opening and closing clamp horizontal type supercritical fluid foaming quick-opening device for the defects that supercritical fluid vertical type kettle bodies are mostly suitable for small experimental devices and the installation and operation space of horizontal type tank body device manhole seal ends is insufficient. Automatic opening andclosing control is adopted for the device. The device is mainly composed of a kettle body assembly, a supporting assembly, a clamp assembly and an end cover opening and closing assembly. The clamp combination face in the clamp assembly and the kettle body longitudinal vertical face of the kettle body assembly are installed in an inclined manner. The clamp assembly is composed of four clamps, a clamping groove is formed in the inner side of each clamp, the warp angle of each clamp is 90 degrees, and each clamp is of a fan-shaped annular structure. Opening and closing of an end cover are achieved through a link mechanism driven by hydraulic push-pull rods. By means of the device, he installation space of equipment is reduced, the operation labor intensity is lowered, and meanwhile the laborefficiency is improved. The four-block combination two-way opening and closing clamp horizontal type supercritical fluid foaming quick-opening device is suitable for supercritical industrialized production of polymer materials.

Description

technical field [0001] The invention relates to the field of polymer material processing, mainly relates to supercritical fluid processing of foaming materials, and in particular to a horizontal supercritical fluid foaming quick-opening device for four-piece combined two-way opening and closing hoops. Background technique [0002] Since supercritical fluid foaming needs to be carried out under relatively high temperature and pressure conditions, the sealing of the kettle body and kettle cover used for supercritical fluid processing is extremely important for the safety and use effect of the equipment. At the same time, the supercritical fluid processing process is an intermittent process. Although there is a pressure relief operation after the material processing is completed, there is still a certain degree of danger in manual operation. It is necessary to improve the automation level of the equipment. [0003] The manhole opening of the supercritical fluid foaming processi...

[0004] Invention patent CN108481650A discloses a horizontal supercritical fluid foaming equipment. In this patent, the tank body is placed horizontally, and the seal of the tank body adopts a combination of tooth engagement and thread compression. Although the clamp assembly and pressure The tight assembly is installed on the track, which reduces the difficulty of its opening and closing operation, but the engagement of the clamp and the locking end of the tank body and the pressing operation of the T-shaped thread are still manual operations, and the opening and closing operation of the tank body has high labor intensity and work efficiency Low; the track-type installation of the clamp assembly and the pressing assembly leads to an increase in the length of the equipment, requiring a large space to facilitate equipment operation and material loading and unloading

The locking assembly at the sealing end of the equipment, the end cover assembly and the tank body are all split structures and move through rails, so it is necessary to set up rail installation platforms for the two components, resulting in increased equipment installation and operating space
