Embodiment 1

[0057] Such as figure 1 As shown, it is a pure titanium flat double vacuum vessel of the present invention, which includes a titanium outer tank 1 and a titanium inner tank 2, the titanium inner tank 2 is sleeved in the titanium outer tank 1, and the space between the titanium inner tank 2 and the titanium outer tank 1 is Vacuum structure; the shape of the vessel structure is a columnar body with an oval and / or kidney-shaped cross section, and it is subjected to vacuum treatment.

[0058] Further, as Figure 4 As shown, the titanium outer bladder 1 includes a side wall 6 and a bottom 7; the edge of the bottom 7 is provided with a protrusion, and the protrusion supports the inner side of the bottom of the side wall 6, and the raised edge is welded to the bottom end surface of the side wall 6. This structure The combination is also known as the "inner support + lap" method. This setting method is to prevent the problem of vacuum suction; the two can be specifically argon arc we...

Embodiment 2

[0063] Embodiment 2, the preparation of pure titanium flat double vacuum vessel

[0064] The preparation method of pure titanium flat double vacuum vessel of the present invention specifically comprises the following steps:

[0065] (1) hydroforming the blank pure titanium to obtain the side wall and bottom of the titanium inner tank and the side wall and bottom of the titanium outer tank; then laser cutting to ensure that the side wall and bottom of the titanium outer tank are consistent with the side wall and Bottom trimming and size; spin forming to ensure the shape and size of the side wall and bottom of the titanium outer tank, the side wall and bottom of the titanium inner tank, and the opening; ultrasonic cleaning to ensure the side wall and bottom of the titanium outer tank , The cleanliness of the side wall and bottom of the titanium liner;

[0066] Five-pointed stars and horizontal bars are processed on the outer wall of the side wall of the titanium outer tank, and...

Embodiment 3

[0070] Embodiment 3, performance measurement of pure titanium flat double vacuum container structure

[0071] According to the pure titanium flat double vacuum container structure (pure titanium flat double vacuum kettle) prepared in the embodiment of the present invention 2, carry out following performance measurement:

[0072] 1. Insulation performance test

[0073] According to GB / T 29606-2013 6.8, the pot body is exposed to the ambient temperature of 20°C±5°C, placed for more than 30 minutes, filled with boiling water (100°C) to the lower end of the sealing rib, and the measured temperature of the water temperature in the pot body reaches 95°C±5°C When the temperature is 1°C, immediately tighten the plug and lid of the pot, place it in a test chamber with a temperature of -30°C ± 2°C, and measure the water temperature in the pot after 12 hours. The water temperature should not be lower than 45°C and 40°C respectively.

[0074] The present invention measures according to ...

Abstract

The invention discloses a pure titanium flat double-layer vacuum vessel structure and a preparation method thereof. The pure titanium flat double-layer vacuum vessel structure comprises a titanium inner container and a titanium outer container, wherein the titanium inner container is nested in the titanium outer container; a vacuum structure is formed between the titanium inner container and the titanium outer container; the shape of the vessel structure is a columnar body having an elliptical and / or waist-shaped cross section; sidewalls and bottoms of the titanium inner container and the titanium outer container are welded in an "internal support + edge" manner respectively; a five-pointed star and horizontal strip ribs are arranged on an outer wall of the side wall of the titanium outercontainer; horizontal strip ribs are arranged on an inner wall of the side wall of the titanium outer container, which can play a role in reinforcement so as to prevent vacuum collapse. The pure titanium flat double-layer vacuum vessel structure is simple in process, is easy to weld, and can improve the rigidity and strength of a pure titanium material.

Description

technical field [0001] The invention relates to a pure titanium flat double-layer vacuum container structure and a preparation method thereof. Background technique [0002] Studies in recent years have shown that aluminum can disturb the metabolism of the human body and cause slow and long-term harm to human health. At the same time, due to the high thermal conductivity of aluminum, when bringing boiling water in summer, the aluminum kettle is likely to cause burns; in the cold winter, the water will be frozen in the kettle. , healthy and portable water bottle. As far as heat preservation containers are concerned, vacuum heat preservation technology is the best heat preservation method at present. Stainless steel vacuum heat preservation cups and pots on the market have small capacity and are mostly round, which is not easy to carry and is not suitable for outdoor survival. In addition, the butt welding method is usually adopted in the technology of the heat preservation v...
