An outer cover with a pressure relief channel is connected with the opening part of a tank body in a square screw thread matching manner; a plug body structure which is made of elastic materials and can be compressed by the outer cover is arranged between the opening part of the tank body and the outer cover; a matching position of the plug body structure and the opening part of the tank body is a tapered bevel which can be sealed; the external diameter of the tapered bottom surface of the plug body structure is greater than the internal diameter of the opening part of the tank body; a channel communicating the space of an inner cavity of the tank body with the outside in an outer cover penetrating manner is formed in the plug body structure; an anti-explosion structure is arranged in the channel; a compressed structure can be detachably arranged in the channel of the plug body structure; the anti-explosion structure is arranged in the channel in the manner that the bottom end surface of the compressed structure is propped between the opposite end surfaces of stepped holes of the plug body structure. Based on the structure of the digestion tank, the anti-explosion structure can be replaced, taken or placed more conveniently. If necessary, a sensor for detecting tank parameters/environments such as temperature, pressure and the like in the tank can be arranged in the channel of the plug body structure. Thus, the application range of the digestion tank is enlarged.
Description
Technical field
The utility model relates to a kind of microwave pressure digestion solubilizing reaction container of realizing the superpressure automatically unloading, is a kind of improvement to existing this series products.
Background technology
Microwave sample digestion technology is in industry, agricultural, and environmental protection, sanitary inspection, metallurgy, geology, medicine, there has been extensive use in the departments such as chemical industry.Sealed high pressure microwave digesting tank wherein is requisite digestion container equipment in this technology application.Owing to being airtight heating under HTHP, so the security of sealed high pressure microwave digesting tank is very important.For solving early stage sealed high pressure microwave digesting tank in the pressure sharp increase situation that runs into some accident or burst, lack the release of effectively mediating rapidly while with processing pressure, increasing severely, Chinese patent CN2668239Y provides a kind of digester of improved sealing type pressure microwave reaction, employing is provided with explosion-proof area and a blast resistance construction with less thickness ringed perimeter section in the inner cap of traditional structure, and covers outside and be provided with the channel design that is in communication with the outside.Occurred exceeding in clearing up course of reaction while by inner cap, being somebody's turn to do than the pressure sharp increase situation of the normal pressure relief capability of minimal thickness ringed perimeter section, can break through the thinner blast resistance constructions such as burst disk of this thickness and through this channel design, pressure be mediated quickly and effectively, avoid having an accident.Find in practice, though this structure has improved safety guarantee, the replacing of the blast resistance constructions such as burst disk picks and places still inconvenient, and this single purposes structure has also been brought the inconvenience in the practical application.
The utility model content
For above-mentioned situation, the utility model provides a kind of further improved novel seal high-pressure microwave digester, can address the above problem satisfactorily.
The utility model novel seal high-pressure microwave digester, it is the further improvement on the similar digester architecture basics of above-mentioned document, be connected with enclosing cover with pressure release passage in the same classical prescription threaded engagement of tank body oral area, be provided with the elastomeric material cock body structure that can be compressed by enclosing cover between tank body oral area and enclosing cover, the matching part of cock body structure and tank body oral area is for can realize the cone inclined-plane that seals, and the cone bottom surface external diameter of cock body structure is greater than the internal diameter of tank body oral area.Be provided with to run through the enclosing cover mode and be communicated with the passage in tank inner chamber space and the external world on the cock body structure, be provided with the blast resistance construction of the forms such as burst disk in passage.Wherein, detachably be provided with a compressing structure in the passage of cock body structure, the mode that said blast resistance construction is pressed in the bottom face of compacted structure top between the stepped hole opposing end surface of cock body structure is arranged in this passage.
In above-mentioned novel seal high-pressure microwave digester structure, a kind of further optimal way, to make the sagittal plane shape of said blast resistance construction consistent with the radial section shape of said passage in the cock body structure, thereby can open this compressing structure of for top, pressing, namely can change/dismounting blast resistance construction easily.
Dismantled and assembled mode in said structure between said compressing structure and cock body structure channel, can select in variety of way at present commonly used, as dogging, wear the different modes such as pin, pintle hook lock, screw thread, wherein preferably thread fiting mode is more easily used all in operation.
On the said structure basis, for further guaranteeing safety, the optimal way that adopts that can also separately or mutually combine comprises: one of optimal way, to be provided with a undergauge structure at the axial middle part of said cock body structure, its diameter is less than the internal diameter of tank body oral area, after pressure tank surpassed preset value in tank, this undergauge structure can more be conducive to bore in the elastomeric material cock body structure that inclined-plane coordinates with the tank oral area gradually turning over of thin edges position and stick up and pressure release.
Two of optimal way, be that said tank body is adopted as the form that is comprised of the outer tank that is nested with cooperation and inner canister, and said cock body structure only needs to coordinate and get final product with the oral area of inner canister.Wherein by inner canister, clear up sample, outer tank can be used as the intensified safety protection, has effectively improved safety guarantee.
Sealed high pressure microwave digesting tank after the above-mentioned improvement of the utility model, in the situation that guarantee and can further improve security performance and guarantee, not only can make the replacing of the blast resistance constructions such as burst disk commonly used pick and place more convenient on the one hand, and after when not using blast resistance construction, it being taken out, the passage of this cock body structure can also be as required, be used for arranging the sensor as tank inner canister parameter/environment such as detected temperatures, pressure, increased the purposes scope.
Below in conjunction with the specific embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made, all should be included in scope of the present utility model.
