Description

A kind of fish biological respinse bag

Technical field

The utility model relates to a kind of reaction bag, specially a kind of fish biological respinse bag.

Background technique

Usual fish feed fermentation reaction method is with plastic bag sealing or with cylinder, fermenting tank for fermentation, polybag capacity Small, poor toughness, leakproofness is poor, and cylinder or fermentation vat difficulty reach sealing, takes trouble, is easy microbiological contamination, in the factorial production, fermentation Equipment cost is high, and then solves these problems using fermentation bag.

Currently, solid state fermentation reaction bag, there are mainly two types of form, one kind is two layers bag, and inner bag is higher by outer bag 7-10cm, Sealing operation is time-consuming, and the natural pressure difference after tunning production gas is vented to sack, and exhaust effect is poor；Another kind is that micropore is saturating Broken bag easily occurs for air film, not reproducible utilization, single ply bag.Two class fermentation bags are Openmouthed bag, not can guarantee in slack storage, remove Microbiological contamination during fortune.Therefore we make improvement to this, propose a kind of fish biological respinse bag.

Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment: as shown in Figure 1, Figure 2 and Figure 3, a kind of the utility model fish biological respinse bag, including outer bag 1, outer bag 1 inside is equipped with the first inner membrance 2, and 4 or less the part of oral area of the first inner membrance 2 is fixedly connected with the inner wall of outer bag 1, the first inner membrance 2 internal sleeve is equipped with the second inner membrance 3, and the oral area 4 of the second inner membrance 3 is fixedly connected with 2 oral area 4 of the first inner membrance, and the two of the first inner membrance 2 Side is fixed with air inlet pipe 6, and one end of air inlet pipe 6 passes through outer bag 1, and air inlet pipe 6 is equipped with ventilation switch 7, and air inlet pipe 6 is worn The one end for crossing outer bag 1 is fixed with purification device 8, and purification device 8 is by 11 groups of sleeve 9, the first filter plate 10 and the second filter plate At the inside of sleeve 9 is fixedly connected with the first filter plate 10, and sleeve 9 is connected with the second mistake far from the threaded one end of ventilation switch 7 Filter plate 11 is equipped with air filtration cotton 12 between first filter plate 10 and the second filter plate 11.

Wherein, the outside of the second filter plate 11 is fixed with handle 13, when needing to replace air filtration cotton 12, The second filter plate 11 is rotated by handle 13, the second filter plate 11 is removed, old air filtration cotton 12 is taken out into replacement, replacement After, the second filter plate 11 is installed can be in situ.

Wherein, oral area 4 is suppressed with dotted line band 5 by marking press, by a dotted line band 5, can more easily will be in first Film 2 and the second inner membrance 3 are torn, and practicability is improved.

Wherein, outer bag 1 is woven bag, and the solid good toughness of outer bag 1 carries convenient advantage.

Wherein, the first inner membrance 2 is semi-permeable membrane, and the second inner membrance 3 is ventilated membrane, passes through the first inner membrance 2 of the double-deck different structure Not only have the effect of that bearing is strong, air permeability effect is good to form compacted zone with the second inner membrance 3, but also not easy infection simultaneously Bacterium.

Wherein, the height of 1 oral area 4 of outer bag is bigger than the height for being higher than 2 oral area 4 of the first inner membrance, is arranged by this kind, external When the oral area 4 of bag 1 is sealed, avoids and seal outer bag 1 and the first inner membrance 2 together, improve practicability.

When work, not only have by the first inner membrance 2 and the second inner membrance 3 of the double-deck different structure to form compacted zone The effect that bearing is strong, air permeability effect is good, and it is not easy bacterial infection simultaneously, cooperate outer bag 1, so that stacking the reaction bag process Be not susceptible to rise bag, leak-off pocket the case where, since the material itself of the first inner membrance 2 and the second inner membrance 3 is nontoxic, protect microorganism Activated state is held, enables microorganism aerobic fermentation and anaerobic fermentation same by the first inner membrance 2 and 3 double membrane structure of the second inner membrance It is carried out under one environment, the first inner membrance 2 and 3 two membranes of the second inner membrance have a lamellar spacing, can play slow except separating between upper and lower opening Punching effect can carry out tolerance to the tolerance of the air entered in the first inner membrance 2, pass through the first filtering by ventilation switch 7 Air filtration cotton 12 between plate 10 and the second filter plate 11 can in advance purify the air being passed into air inlet pipe 6, It prevents large granular impurity from entering the inside of the first inner membrance 2, when needing to replace air filtration cotton 12, passes through handle 13 The second filter plate 11 is rotated, the second filter plate 11 is removed, old air filtration cotton 12 is taken out into replacement, it, will after replacement The installation of second filter plate 11 can be in situ, which uses preceding internal aseptic, is convenient for long term storage after charging, carries that convenient this is anti- It can be continued to use after answering bag to clean degerming, environment-protection low-consumption improves practicability.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
