Description
Technical field
The utility model is related to field of pharmaceutical equipment, more particularly, to a kind of supercritical CO of good seal performance2Extraction
Kettle.
Background technology
Existing supercritical CO2The extraction kettle head cover used in extraction equipment, which is adopted, to be screwed, and opens pressure or gas every time
When opening pressure, although full gate valve, it is slow to open pressure, finds still there is slug phenomenon in rewinding, and also result in pipeline and
The capsule contamination of period.And screw is backed out due to often screwing on, and it is flash or damage more and more, production cost is increased, separately
Outside, it is extremely difficult to unanimously, there may be alice phenomenon due to being screwed in the power of pressurization, it is closely sealed not tight.
Utility model content
The purpose of the utility model is to overcome the above deficiency, the high extraction kettle of a kind of good airproof performance, safety coefficient is designed.
To achieve the goals above, the utility model provides a kind of supercritical CO of good seal performance2Extraction kettle, including it is upper
The barrel and head cover positioned at upper barrel top, the blanking tube and bottom cover positioned at blanking tube bottom end, blanking tube are located under upper barrel
Side, the part that the upper barrel and blanking tube inner wall are connect with head cover and bottom cover are equipped with internal thread, and internal thread bottom is equipped with close
Seal, the head cover and bottom cover are set as threaded embedded lid.
Upper barrel described in the utility model is used with blanking tube and is threadedly coupled.
Head cover and bottom cover described in the utility model are internally provided with detachable stainless steel filtering net, and strainer is equipped with layer 2-4, strainer
Aperture is 30-60 mesh.
One layer of filter paper is equipped between strainer and head cover and bottom cover described in the utility model.
Head cover and bottom cover described in the utility model are equipped with multiple equally distributed air holes.
Compared with prior art, the beneficial effects of the utility model are：The extraction kettle barrel that the utility model uses and top
The connection type of lid and bottom lid makes extraction kettle fix more firm, and uniform force, safety index greatly promotes, and improves sealing
Property can effectively prevent powder to overflow, and powder can be blocked within barrel by the setting of strainer and filter paper, and easy to installation and removal,
It is convenient to clean.The utility model good airproof performance, safety coefficient is high, avoids the waste of raw material, has ensured the safety of worker.
