Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation。These accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is only described in a schematic way, and therefore it only shows the composition relevant with the present invention。
Change as shown in Figure 1 to 4 and amendment。The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right。
As shown in Figure 1, the chain-linked conveyer 100 of the present invention includes: body 10, the internal conveying space limited for carrying material of above-mentioned body 10, one end of above-mentioned body 10 has charging aperture 101, the other end has discharge port 102, and above-mentioned conveying space can pass through charging aperture 101 and discharge port 102 and be connected externally to lead to。According to the conveying direction of material, charging aperture 101 is positioned at the upstream of material conveying, and discharge port 102 is positioned at the downstream of material conveying, material enters in conveying space by charging aperture, and in conveying space under the drive of chain, be transported to discharge port, and discharge from discharge port。
Coordinating with reference to shown in Fig. 2, Fig. 3, Fig. 4, above-mentioned discharge port 101 is provided above running through the main shaft 20 of above-mentioned body 10, and this main shaft 20 can own axes be that rotating shaft rotates, thus playing the effect of transmission。In order to realize the sealing of this main shaft 20, the two ends of above-mentioned main shaft 20 are provided with sealing device 30, and any one in the sealing device 30 at two ends includes: one end embeds the rotating seal ring 301 in above-mentioned body 10 and fixed seal ring 302 and immersion oil packing 40。
Wherein, rotating seal ring 301 is set on above-mentioned main shaft 20, and can be synchronized with the movement with main shaft 20。Preferably, rotating seal ring 301 is installed on above-mentioned main shaft 10 by least two holding screw 303, to be locked by rotating seal ring 301, it is prevented that occur when it rotates to loosen。Fixed seal ring 302 is then fixed on body 10, and keeps geo-stationary with body 10, and the lateral wall of the medial wall of this fixed seal ring 302 and rotating seal ring 301 is oppositely arranged, and is assembled together, and ensures the two dead in line simultaneously。Specifically, the first projection 3011 that is that the lateral wall of rotating seal ring 301 is formed some annulars and that be parallel to each other, the second projection 3021 that is that the inner side of fixed seal ring 302 is formed with some annulars and that be parallel to each other。When rotating seal ring 301 and fixed seal ring 302 are assembled together realization sealing, some first projections 3011 are between above-mentioned some second projections 3021, and some first protruding 3011 have certain distance with the lateral wall of rotating seal ring 301, the area of the sealing surface formed when so adding the two assembling, enhances sealing effectiveness。
After rotating seal ring 301 and fixed seal ring 302 are assembled, therebetween the space formed further seals, above-mentioned immersion oil packing 40 is between some second projections 3021, namely between some first protruding 3011 and the lateral wall of rotating seal ring 301。But for tangible object, still forming tiny gap after assembling, the present invention is in order to above-mentioned sealing gap, be filled with sealing gas in the space between above-mentioned rotating seal ring 301 and fixed seal ring 302。Correspondingly, the chain-linked conveyer 100 of the present invention also includes: blanket gas body feeding 50。
Above-mentioned blanket gas body feeding 50 includes: air accumulator 501, booster pump 502 and trachea 503。Wherein, space between above-mentioned rotating seal ring 301 and fixed seal ring 302 is connected by trachea 503 with air accumulator, under the effect of booster pump 502, the sealing gas in air accumulator 501 can be pumped in the gap between rotating seal ring 301 and fixed seal ring 302。Correspondingly, above-mentioned fixed seal ring 302 offers air inlet, above-mentioned air inlet is connected with the space between rotating seal ring and fixed seal ring, one end of trachea 503 is connected with above-mentioned air inlet, thus sealing gas by trachea from the space that air inlet enters between rotating seal ring and fixed seal ring。As a kind of embodiment, above-mentioned sealing gas can be the inactive gas such as nitrogen。
In addition, in order to make to be formed between fixed seal ring 302 and body 10 good sealing, the outside of above-mentioned fixed seal ring 302 is also formed with the 3rd projection 3022 of the annular leant with the wall of above-mentioned body 10, thus increasing fixed seal ring 302 to contact the area of the sealing surface formed with body 10。
To sum up above-mentioned, the chain-linked conveyer simple in construction of the present invention, sealing is strong, dust-proof, explosion-proof effect good, has higher safety coefficient。Meanwhile, its convenient disassembly, maintenance cost is low。
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when without departing substantially from the spirit of the present invention or basic feature, it is possible to realize the present invention in other specific forms。Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention rather than described above limits, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in the present invention。Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved。
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that。
