The base (1) of the preparation device adopts a frame structure; a gas inlet (2) and a gas outlet (3) are formed in the lower part of the base (1); limiting plates (4) are arranged on the inner side walls of the base (1); an upper cover (5) is an upper cover with a cavity; a pressing block (6) is arranged in the upper cover (5); an ejector rob (7) is vertically arranged at the upper part of the upper cover (5) in a penetrating manner; the lower end of the ejector rob (7) is fixedly connected with the pressing block (6); the ejector rob (7) is connected with the upper cover (5) through threads; grooves (9) are formed in the upper end face of the base (1); sealing rings (8) are embedded into the grooves (9). The preparation device provided by the utility model is used for preparing the nanocellulose composite membrane.
Description
Technical field
The utility model relates to a kind of composite membrane preparation facilities, is specifically related to a kind of nano-cellulose composite membrane preparation facilities.
Background technology
Bacteria cellulose forms unique texture, and because of " nano effect " have high-hydroscopicity and high-moisture-retention, the high permeability to liquids and gases, high wet strength, especially can original position machine-shaping under hygrometric state etc. characteristic.High purity and excellent performance make the bacteria cellulose fibre can be in special dimension widespread use.The preparation method of bacteria cellulose is varied, but the once-combined film of the every preparation of existing bacteria cellulose preparation facilities all needs to adopt silicone oil or paraffin to carry out once sealing, preparation procedure complexity, and cost is high.
Utility model content
The purpose of this utility model is all to need to adopt silicone oil or paraffin to carry out once sealing in order to solve the once-combined film of the every preparation of existing bacteria cellulose preparation facilities, preparation procedure complexity, the problem that cost is high, and then a kind of nano-cellulose composite membrane preparation facilities is provided.
The technical solution of the utility model is: a kind of nano-cellulose composite membrane preparation facilities comprises base, described base is skeleton construction, the bottom of base is respectively equipped with air inlet port and production well, the inner side-wall of base is provided with limiting plate, described nano-cellulose composite membrane preparation facilities also comprises upper cover, briquetting, push rod and sealing-ring, described upper cover is the upper cover with cavity, briquetting is arranged in upper cover, push rod is vertically located in the top of upper cover, and the lower end of push rod is fixedly connected with briquetting, between push rod and upper cover, be threaded connection, the upper surface of base is provided with groove, sealing-ring is embedded in groove, upper cover mounts cover on base, and be contained on base by briquetting sealing cover.
The shape of cross section of described base and upper cover is circle or rectangle.
Described push rod comprises leading screw, coupling end and screws end, screws end, leading screw and coupling end and is from top to bottom fixedly connected sequentially.
Described briquetting passes through the removable setting of push rod in upper cover.
The utility model compared with prior art has following effect:
1. the utility model compared with prior art, set up upper cover, and realized the sealing to base by the briquetting in upper cover, in upper cover, be provided with push rod, operator only need screw push rod, push rod drives the downward compacting sealing-ring of briquetting, thereby reaches sealing effectiveness, and sealing means is simple to operate, and sealing means of the present utility model has adopted sealing-ring, sealing circle is existing mature technology, and good sealing effect is with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises base 1, described base 1 is skeleton construction, the bottom of base 1 is respectively equipped with air inlet port 2 and production well 3, the inner side-wall of base 1 is provided with limiting plate 4, described nano-cellulose composite membrane preparation facilities also comprises upper cover 5, briquetting 6, push rod 7 and sealing-ring 8, described upper cover 5 is the upper cover with cavity, briquetting 6 is arranged in upper cover 5, push rod 7 is vertically located in the top of upper cover 5, and the lower end of push rod 7 is fixedly connected with briquetting 6, between push rod 7 and upper cover 5, be threaded connection, the upper surface of base 1 is provided with groove 9, sealing-ring 8 is embedded in groove 9, upper cover 5 mounts cover on base 1, and be contained on base 1 by briquetting 6 sealing covers.
As optimal way, the base 1 of present embodiment and the shape of cross section of upper cover 5 are circle or rectangle.Be convenient to meet the processing of difform nano-cellulose composite membrane.
As optimal way, the push rod 7 of present embodiment comprises leading screw 7-1, coupling end 7-2 and screws end 7-3, screws end 7-3, leading screw 7-1 and coupling end 7-2 and be from top to bottom fixedly connected sequentially.Reach best functional effect by the most succinct structure, with low cost, effectively exert pressure for briquetting 6, and adopt the connection mode of leading screw, the leakage phenomenon of also effectively having avoided briquetting 6 to cause because of dropout in the static cultivation process that reaches 5-14 days.
As optimal way, the briquetting 6 of present embodiment passes through the removable setting of push rod 7 in upper cover 5.Be convenient to realize the sealing between base 1 and upper cover 5.
Working process of the present utility model is:
First will be placed in inverted culture vessel 11 by the deployed function nano particle 10 of concrete data and fermentation culture matrix, due to action of gravity, function nano particle 10 is deposited on oxygen flow material membrane 12, at this moment upper cover 5 is mounted cover on base 1, and screw the push rod 7 on upper cover 5 tops, the briquetting 6 that push rod 7 withstands upper cover 5 inside by leading screw 7-1 moves down, the upper surface that briquetting 6 is pressed into base 1 is provided with in groove 9, sealing-ring 8 is embedded in groove 9 simultaneously, when briquetting 6 is pressed into groove 9, the sealing-ring of compacting simultaneously 8, can reach sealing effectiveness.Then leave standstill after one hour, to constantly oxygen supply in oxygen room 13, carry out the static cultivation of 5-14 days at 30 DEG C, at this moment bacteria cellulose film forms gradually, and function nano particle 10 just can be inclusive in bacteria cellulose film more equably.
