Abstract

A kind of vacuum insulation antistaling device for storing beer consists of glass liner, casing, sealing cap on the top of the liner and electric beer-sucker installed on the sealing cap. The characteristic lies in that between the glass liner and casing there is an adiabatic layer composed of heat insulation layer of heat insulation material and vacuum heat insulation layer. The glass liner is fixed on the holdfast installed at middle or lower part of the casing.

Description

Vacuum and thermal insulation type preservation apparatus

The invention belongs to draft beer antistaling container technical field.

In the prior art, China Patent No. is 95234166.2 and is called the technical scheme that the patented technology of " novel beer antistaling container " provides, and exists following defective: 1. single thermal insulation layer design causes being incubated undesirable; 2. the suffered fulcrum of inner bag very little, only inner bag top is fixed, and easily causes the distortion of inner bag.

The objective of the invention is to design a kind of vacuum and thermal insulation type preservation apparatus, it constitutes adiabatic layer by two thermal insulation layers, further prolongs storage period, and inner bag is difficult for the displacement damage simultaneously.

The object of the present invention is achieved like this: vacuum and thermal insulation type preservation apparatus comprises inner bag, shell, seal cover cap and electronic suction drinking vessel, it is characterized in that being provided with between inner bag and the shell adiabatic layer of warm material thermal insulation layer and vacuum heat-insulating layer formation; Shell middle inside or bottom are provided with the fixedly anchor fitting of inner bag, and this anchor fitting is that a T type is protected middle part or the bottom formation that frame is welded in the shell inboard.

The invention has the advantages that: owing between inner bag and shell, be provided with two heat-insulating adiabatic layers, the temperature retention time that can further prolong beer, the effect owing to anchor fitting simultaneously is positioned in the shell inner bag more securely.

Accompanying drawing is a structural representation of the present invention.

Number in the figure is:

1, electronic suction drinking vessel; 2, seal cover cap; 3, wine inhaling tube; 4, warm material thermal insulation layer;

5, vacuum heat-insulating layer; 6, anchor fitting; 7, the mouth of bleeding; 8, warm material thermal insulation layer shell;

9, inner bag; 10, shell

In conjunction with the accompanying drawings embodiments of the invention are specified:

The material of inner bag of the present invention (9) is a corrosion-resistant steel, and warm material thermal insulation layer shell (8) is fixed on the inner bag (9), makes to form a cavity between the two, injects warm material and make it to form warm material thermal insulation layer (4) in cavity.The shell (10) that again its lower inside is provided with anchor fitting (6) is welded on the inner bag (9), makes cavity become vacuum air extraction between the two with air pump.The making of electronic suction drinking vessel (1), seal cover cap (2) and wine inhaling tube (3) and using method are identical with patent 95234166.2.

Claims (2)

1, a kind of vacuum and thermal insulation type preservation apparatus comprises inner bag, shell, seal cover cap and electronic suction drinking vessel, it is characterized in that: be provided with the adiabatic layer that warm material thermal insulation layer and vacuum heat-insulating layer constitute between inner bag and the shell.

2, vacuum and thermal insulation type preservation apparatus according to claim 1 is characterized in that: shell middle inside or bottom are provided with the fixedly anchor fitting of inner bag.
