Embodiment 1

[0026] according to figure 1 , a new type of passive insulation bucket, which includes a bucket cover 1 and a cylinder body composed of an outer shell 4 and an inner lining layer 9; a heating layer 6 and a heating layer are sequentially arranged between the outer shell and the inner lining layer from inside to outside Insulation layer 5; a heating bag 7 is provided in the heating layer; a gland 8 is provided on the heating layer and the insulation layer; a groove 2 that is buckled on the barrel is provided on the bottom of the barrel cover 1; The outer ring of the groove is provided with a rubber ring 3 .

[0027] The top surfaces of the heating layer 6 and the thermal insulation layer 5 are lower than the top surfaces of the outer casing 4 and the inner lining layer 9, and are flush with the outer casing and the inner lining layer after the gland 8 is fastened.

[0028] The heating layer 6 is arranged on the circumference of the inner lining layer 9 ; the thermal insulation ...

Embodiment 2

[0035] A heating bag, the outer layer is an air-tight plastic film layer, the inner layer is a breathable non-woven fabric layer, and the inner layer is wrapped with a heating agent, and the heating agent is prepared according to the following process:

[0036] Add mullite, brucite, sepiolite and activated carbon to the crusher in sequence according to 3:2:2:1 for crushing, and then grind to obtain a powder with a particle size of 50 mesh, which is component A;

[0037] Add iron and alumina to the ball mill in turn, and grind the mixture until the particle size is 50 mesh, which is component B;

[0038] Calcinate diatomite and kaolin at 600°C for 30 minutes, and then crush them into 100-mesh powder, which is component C;

[0039] Put component A, component B, component C and water into the stirred tank reactor sequentially according to the mass ratio of 5:3:2:10, stir at 500rpm for 10min, let it stand for 60min, take it out, and prepare a particle size of 20 mesh Granules wer...

Embodiment 3

[0041] The performance test of the heating bag of the embodiment of the present invention 2:

[0042] Choose a bag length of 120mm, bag width of 100mm, and moisture permeability of 300g / m 2 .d; The weight of each bag of heating agent is 30g. Remove the outer film layer when using.

[0043] Ambient temperature: 15±2℃, humidity 40-60%.

[0044] Heating time: the time required for the sample to heat up to 60°C from the start of heating.

[0045] Maximum temperature: The highest temperature measured by the sample heating.

[0046] Duration: After the sample heats up, it starts from 40°C and returns to 40°C after the highest temperature.

[0047] Control group 1 does not add sepiolite and activated carbon, and the rest is the same as in embodiment 2; control group 2 does not add diatomite and kaolin, and the rest is the same as in embodiment 2. Three parallel groups were set up for each group, and the average value was taken. The parameters of each group are shown in Table 1:...

Abstract

The invention belongs to the technical field of insulation barrels, and discloses a novel passive insulation barrel. The novel passive insulation barrel comprises a barrel cover and a barrel body composed of an outer shell and a lining layer; a heating layer and an insulating layer are sequentially arranged between the outer shell and the lining layer from inside to outside; heating bags are arranged in the heating layer; a gland is arranged on the heating layer and the insulating layer; a ring of a groove buckled to the barrel body is formed in the lower surface of the barrel cover; a rubber ring is arranged on the outer circle of the groove. According to the novel passive insulation barrel, the structure is reasonable; by arranging the insulating layer and the heating layer, long-time insulating on articles contained in the lining layer can be achieved without an external power source or fire source, and the technical problems that an insulation barrel in the prior art is poor in insulating effect and more in confined condition are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of heat preservation barrels, and in particular relates to a novel passive heat preservation barrel. Background technique [0002] The heat preservation bucket is mainly used to hold food or other items, and its purpose is to ensure that the things contained in it can be kept warm for a long time. [0003] The thermal insulation barrel of the prior art is provided with a thicker barrel wall, and the bottom of the barrel is provided with a heating device, which can keep the interior of the barrel in a heat preservation state for a long time after being energized. Although this kind of thermal insulation bucket has a good effect, it will lose its thermal insulation effect once the power is cut off, especially in outdoor places that require long-distance transportation, such as mining, railway construction, field exploration, etc., there is no external power supply, and the terrain conditions are bad You have ...
