The utility model discloses a main element is the orifice plate, expands small hole diameter on the orifice plate to 20mm, reach its quantity by 490 reductions to 80, at the additional 100 purpose stainless wire net of one deck of the dorsal part of orifice plate, both can place the molecular sieve like this and reveal under stainless wire net's of the blockking again, leave sufficient area of contact for the molecular sieve on guaranteeing the orifice plate again, orifice plate out of use rig floor drilling after the improvement, because the increasing in aperture, the unloading is cut by plasma cutting machine by computer programming again to the preparation of orifice plate, the shaping of whole orifice plate one -step refining, the process time of an orifice plate is only less than 6 minutes.
Description
Technical field
This utility model relates to the closing field of molecular sieve, particularly relates to locking device and the pressure vessel thereof of a kind of molecular sieve.
Background technology
The pressure vessel of existing splendid attire freezing liquid, the low-temperature heat-insulation pressure container being made up of inner pressurd vessel, shell and vacuum heat-insulating layer, inner pressurd vessel plays a part holding low-temperature liquid, and shell plays and contains inner pressurd vessel, and forms the effect of vacuum interlayer with inner pressurd vessel.In order to ensure the service life of vacuum interlayer, need to place inside interlayer to adsorb the adsorbent " molecular sieve " continuing the slowly gas of releasing inside interlayer." molecular sieve " needs to be placed on inner pressurd vessel side, and the device of existing splendid attire molecular sieve is entitled " technique manhole ", at the lid of its exit welded closure, forms the locking device of molecular sieve.Molecular sieve diameter about 2.5～3mm, in order to ensure the molecular sieve contact area to vacuum interlayer gas, and can not leak from locking device, the existing practice is to open the aperture of multiple diameter 2mm on the cover plate playing sealing process, owing to aperture is too small, and enormous amount, general needs about 500, so causing workload the biggest, one workman one bench drill, needing nearly 8 hours, but also can damage 5 drill bits, such workload and manufacturing cost are at a relatively high.
So, now it is badly in need of one and is easy to processing, with low cost, what using effect was good is used for closing the device of molecular sieve.
Utility model content
The purpose of this utility model is to provide locking device and the pressure vessel thereof of a kind of molecular sieve, solves the problem that molecular sieve makes difficulty, cost is high of prior art.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
The locking device of a kind of molecular sieve of this utility model and pressure vessel thereof, including technique manhole and the orifice plate being fixed on technique people's hole exits；Described orifice plate is the metallic plate with multiple circular holes；The charging port of with closure it is additionally provided with on described orifice plate；The silk screen that one layer of aperture is not more than 2.5mm is set at the back side of described orifice plate.
Further, the material of described orifice plate is rustless steel.
Further, described orifice plate is evenly equipped with 50-100 circular hole.
Further, described orifice plate is evenly equipped with 80 circular holes.
Further, a diameter of 15-25mm of described circular hole.
Further, described silk screen is the stainless steel cloth of 100 mesh.
Further, described silk screen is fixed on the back side of described orifice plate by spot welding, and the distance between each solder joint is equal.
Further, a kind of pressure vessel, including inner pressurd vessel and shell, described inner pressurd vessel is provided with the locking device of any one molecular sieve described above, and inside the locking device of molecular sieve, fills molecular sieve.
Compared with prior art, Advantageous Effects of the present utility model is as follows:
Main element of the present utility model is orifice plate, it changes the method that multiple diameter 2mm aperture beaten by foramen primum plate, expand hole diameter on orifice plate to 20mm, reach its quantity to be reduced to 80 by 490, again at the stainless steel cloth of dorsal part additional layer 100 mesh of orifice plate, under the stop of stainless steel cloth, so both can place molecular sieve reveal, and can guarantee that again and leave enough contacts area to molecular sieve on orifice plate；Orifice plate after improvement is holed not in use by rig floor, and due to the increasing in aperture, the making of orifice plate is by computer programming, then by CUT cutting stock, whole orifice plate is processed and formed at one time, and the process time of one piece of orifice plate is only less than 6 minutes.

Detailed description of the invention
As Figure 1-5, the locking device of a kind of molecular sieve and pressure vessel thereof, including technique manhole 1 and the orifice plate 2 being fixed in technique manhole 1 outlet；Described orifice plate 2 is the thin corrosion resistant plate having 80 diameter 20mm, concrete, corrosion resistant plate plasma blanking, after blanking, burr is polished, ensure the air flowing of the molecular sieve in technique manhole and locking device space outerpace, make molecular sieve can absorb extraneous gas.It is additionally provided with the charging port 5 of with closure 4 on described orifice plate 2, is used for filling molecular sieve.At the back side of described orifice plate 2 by the stainless steel cloth 6 of one layer of 100 mesh of spot-welded, each solder joint is arranged uniformly and apart from equal, and replacing small sircle hole with silk screen, cost of manufacture is cheap, effective.
A kind of pressure vessel, locking device by above-mentioned molecular sieve, it is arranged on and has inside the interlayer of inner pressurd vessel and shell, it is in particular on inner pressurd vessel, has opening (internal process needs, the opening for people's turnover opened, later stage needs to seal), technique manhole is welded to opening part (with reference to Fig. 4), to reach to seal the purpose of opening.Then technique manhole being fabricated to locking device by the manufacture method of the locking device of above-mentioned molecular sieve, be filled into molecular sieve, then charging port sealed, complete described pressure vessel, can be used to contain freezing liquid.
Embodiment described above is only to be described optimal way of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
