Description

Pressurized container

Technical field

The present invention relates to a kind of pressurized container.

Background technique

Along with the high speed development of Chinese national economy, large pressurized vessel has obtained extensive propagation and employment in rubber, medicine, food and timber processing and other fields, and progressively to large scale development.

Such as Fig. 1, shown in Figure 2, common large pressurized vessel: comprise the vessel 2 and the lid 3 that are arranged on the pedestal 1, the opening of vessel 2 is provided with the clip 4 that vessel 2 and lid 3 can be fastened togather, that side that is positioned at lid 3 on the clip 4 is provided with a circle clamp teeth 5, be provided with the lid tooth 6 that matches with clamp teeth 5 on the lid 3, be provided with four cylinders 7 on the pedestal 1, the end of the piston rod of cylinder 7 respectively and four cylinder 7 hinged with the outer surface of clip 4 be distributed on vessel 2 around, pedestal 1 is positioned on the position of vessel 2 levels one side and is provided with flygate cylinder 8, a hinged pivoted arm 9 also on the pedestal 1, one end of pivoted arm 9 links to each other with the piston rod of the cylinder 8 that opens the door, and the other end links to each other with the outer surface of lid 3.The working procedure that the lid 3 of above-mentioned pressurized container is opened is: when pressurized container is closed, as shown in Figure 3, clamp teeth 5 on the clip 4 is superimposed with the lid tooth 6 on the lid 3, this moment, the piston rod of control cylinder 7 stretched out, piston rod promotes clip 4 and clockwise rotates,

clamp teeth

5 and 6 dislocation of the lid tooth on the lid 3 on the clip 4 are got final product---as shown in Figure 4, then the piston rod of controlling the cylinder 8 that opens the door shrinks, pivoted arm 9 rotates around the hinged place with pedestal 1 under the effect of the piston rod of the cylinder 8 that opens the door, and pivoted arm 9 drives lid 3 and opens in rotation.The shortcoming of above-mentioned pressurized container is: in this structure rotation, rotating mechanism complexity; Be the profile of tooth engagement between lid and the clip, this structure stress is interrupted, and the processing of process multiple operation, and the precision of each tooth is different, and discontinuity will be born same internal force, can only strengthen the size of part, and material therefor is more; The profiled parts requirement on machining accuracy is high, can't be on general numerical control machine tool after boundary dimension strengthens once clamping finish whole processing, large-size numerical control machine quantity is few, and processing charges are very high; Because lid is very large, uncertain deadweight tenesmus is arranged, regulate the compensation difficulty, can't accurately locate.

Summary of the invention

Technical problem to be solved by this invention is: provide that a kind of opening structure is simple, good seal performance and the efficiently pressurized container that opens the door.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of pressurized container, be arranged on vessel and lid on the pedestal, be fixed with the body clip by screw on the described vessel, be fixed with the lid clip by screw on the lid, be fixed with otic placode on the lid, one end of otic placode is hinged on the pedestal, thereby be provided with on the pedestal and can drive lid and move radially along vessel and realize opening between lid and the vessel, the drive unit that closes, when lid was combined on the vessel, body clip and lid clip were combined and form a complete circular clip.

Described drive unit is oil cylinder, and the base of oil cylinder is hinged on the pedestal, and a side of the piston rod of oil cylinder and otic placode is hinged;

Be used for supporting the support block of otic placode on the described pedestal;

Be provided with a circle groove on the contacted side of described vessel and lid, be provided with seal ring in the groove, be provided with some the gas circuits that connect groove and vessel outside in the wall of vessel;

Seal ring is y-type seal ring.

The invention has the beneficial effects as follows: utilize drive unit to drive lid along the moving radially of vessel, thereby realize the open and close between lid and the vessel, final so that whole pressurized container simple in structure, it is convenient, fast to open the door.

Embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.

Such as Fig. 5, shown in Figure 6, a kind of pressurized container comprises vessel 2 and the lid 3 that is arranged on the pedestal 1, be fixed with body clip 10 by screw on the described vessel 1, be fixed with lid clip 11 by screw on the lid 3, be fixed with otic placode 12 on the lid 3, one end of otic placode 12 is hinged on the pedestal 1, can drive lid 3 moves radially open and close between realization lid 3 and the vessel 2 along vessel 2 oil cylinder 13 thereby be provided with on the pedestal 1.The base of oil cylinder 13 is hinged on the pedestal 1, and a side of the piston rod of oil cylinder 13 and otic placode 12 is hinged.Certainly when actual production, can adopt other combiners to realize above-mentioned functions, do not describe in detail at this.When lid 3 was combined on the vessel 2, body clip 10 and lid clip 11 were combined and form a complete circular clip.In order to reduce the working pressure of oil cylinder, be provided with the support block 14 that when lid 3 is in open mode, is used for supporting otic placode 12 at pedestal 1.As shown in Figure 7, in order to increase the sealing between lid 3 and the vessel 2, and for fear of causing seal ring to damage because of the shearing force that produces between lid 3 and the vessel 2, be provided with a circle groove 15 on vessel 2 and the lid 3 contacted sides, be provided with seal ring 16 in the groove 15, be provided with some the gas circuits 17 that connect groove 15 and vessel 2 outsides in the wall of vessel 2, this gas circuit 17 links to each other with the source of the gas of pressurized container outside, in order to improve sealability, seal ring 16 adopts y-type seal ring usually.

Working principle of the present invention is: as shown in Figure 6, pressurized container is in open mode, the piston rod of controlling oil cylinder 13 this moment shrinks, piston rod drives otic placode 12 and lid 3 rotates counterclockwise around the hinged place of otic placode 12 with pedestal 1, when lid 3 and vessel 2 are combined fully, stop oil cylinder 13 work, this moment, lid clip 11 and body clip 10 just were combined, and formed a complete clip.At last, utilize external air source by gas circuit with seal ring 16 from groove 15 to extrapolation, until the end face of seal ring 16 and lid 3 offsets, thereby realize the sealing of pressurized container.Open pressurized container, as long as operation is opposite.

Advantage of the present invention is: after adopting said structure, the difficulty of processing of whole pressurized container has reduced, and is simple in structure, and switch is convenient.
