Cleaning cabin in cleaning filling cabin
At present, as the inner wall of the PET cask directly contacting with beer, before filling beer into the PET cask, the interior of the PET cask needs to be cleaned, so as to better realize the purpose of aseptic filling. However, most of the traditional cleaning devices can only clean the PET wine casks with the steel casks, and the PET wine casks have different structures of wine lances from the steel casks, so that the traditional cleaning devices cannot be well applied to cleaning of the PET wine casks. Particularly, the wine spear of PET cask is mostly as "a wine spear and be equipped with the cask of this wine spear" like a chinese utility model patent that 9 month 8 th announced in 2020, application number is "201921996860. X", this type of wine spear also calls the wine spear, when going out the wine sealing washer and pressing in to the inside direction of PET cask, the wine spear is in the open mode, at this moment, inside and the outside of going out the wine pipe have two passageways respectively, in the wine process of going out, can fill the gas in the PET cask through external passage and carry out the pressure boost, make beer outwards flow out from internal passage through going out the wine pipe.

In connection with cleaning filling silos
The filling equipment of steel drum is being used along mostly to the filling equipment of current PET cask, adopt the form of inversion filling, it is simpler also more convenient to invert the filling to the steel drum, nevertheless be not fit for filling to the PET cask, its main factor is that the structural strength of PET cask self can be far less than the steel drum, if adopt the inversion filling, along with the continuous pouring into of beer, the stack shell is very easily crooked to appear, the bending appears even, press the problem of disconnected bung hole, consequently, need design extra stack shell and support the mechanism, not only the structure is complicated, the design cost is high, the cooperative control of each equipment also is a big problem.
In addition, when inversion filling, still need set up at the barrel head of PET cask and push down equipment, otherwise can't push up the wine lance for relative motion appears in the play wine sealing washer in the wine lance unable and PET cask, and this undoubtedly also brings very big extra cost for inversion filling equipment.

As shown in fig. 2, the filling valves have three valves, so that three batches of PET barrels are filled simultaneously.
The bottom of filling valve body 2313 has the wine lance pressure tank with the adaptation of wine lance outer wall, the bottom of filling case 2316 has the wine lance clamping ring with the play wine sealing washer adaptation in the wine lance, the wine lance pressure tank communicates with exhaust passage, the wine lance clamping ring is in annotating the end opening department of wine passageway. When the filling valve body 2313 descends under the effect of last cylinder 2311 and docks with the wine lance, the wine lance indent will cover and establish on the wine lance, and when the filling case 2316 descends under the effect of lower cylinder 2315, then accessible wine lance clamping ring is backed down the wine lance sealing washer of opening for annotate the inside passageway that the wine passageway can communicate the wine lance afterwards, and exhaust passage can communicate the outside passageway of wine lance.
The beer filling channel is connected with beer to be filled through a beer filling interface, and the exhaust channel is connected with exhaust gas collecting equipment through an exhaust interface.
During the use, need wait for the PET cask after being washd to get into the filling station, afterwards, can drive filling valve body 2313, internal link 2314, lower cylinder 2315, filling valve core 2316 through last cylinder 2311 earlier and descend in step to make the stable cover of wine lance indent establish on the wine lance, accomplish the butt joint of filling valve body 2313 and wine lance. Thereafter, the filling valve body 2313 is moved downward relative to the filling valve body 2316 by the lower cylinder 2315, so that the wine lance sealing ring is pushed downward by the wine lance pressing ring, the inner channel of the wine lance can be communicated with the wine filling channel on the inner side of the filling valve body, and the outer channel of the wine lance can be communicated with the exhaust channel on the outer side of the filling valve body. Therefore, as shown in fig. 27, the PET wine barrel can be filled efficiently, stably and aseptically, and in the filling process, because the PET wine barrel is always in the upright state, various defects of inverted filling can be avoided, the filling effect is good, and other supporting or clamping equipment is not needed for assistance.
The filling valve further comprises a guide mechanism, the guide mechanism comprises a mounting seat 2321, a guide rod 2322, an upper fixing plate 2323 and a lower fixing plate 2324, the mounting seat 2321 is fixedly connected to the rack and is sleeved with the filling valve body 2313; therefore, the filling valve body can make a more stable linear reciprocating motion under the driving of the upper cylinder, and the tracking performance is better;
the upper fixing plate 2323 is fixedly connected to the cylinder body of the upper cylinder 2311, the upper fixing plate 2323 is fixedly connected to the mounting seat 2321 through the guide rod 2322, the lower fixing plate 2324 is fixedly connected to the lower cylinder 2315, the lower fixing plate 2324 is further sleeved on the guide rod 2322 and is slidably connected to the guide rod, and the upper cylinder 2311, the lower cylinder 2315, the guide rod 2322, the filling valve core 2316 and the filling valve body 2313 are all vertically arranged. Like this, can carry out stable direction at the in-process of the synchronous up-and-down motion of filling valve body 2313, internal connection rod 2314, lower cylinder 2315, filling case 2316 through guiding mechanism for the operation of equipment has better stability and reliability, thereby ensures that stable, the accurate cover of wine lance indent is established on the wine lance.
The filling valve base 2317 is in dynamic seal with the filling valve core 2316 through a bellows seal structure II. Therefore, the dynamic sealing effect is better realized by the corrugated pipe sealing structure.
