Embodiment 1

[0041] Embodiment one, refer to figure 2 and image 3 , in this embodiment, the getter includes a getter sheet 32 ​​having the same cross-sectional shape as that of the sealed cavity, preferably, they are all circular, the getter sheet is coaxial with the sealed cavity, and the getter sheet is at least There are two and equidistantly arranged along the axis of the sealed cavity, similar to a tray; the heating device in this embodiment is an electric heating wire 33, and the electric heating wire is generally helical and coaxially wound outside the getter; this embodiment The mounting bracket 31 includes at least three legs uniformly distributed in the circumferential direction, and the adjacent two legs are connected by connecting rods. Part 311, the installation part includes an upper splint and a lower splint, an installation area for installing the getter sheet and facing the axis of the sealed cavity is formed between the upper splint and the lower splint, the getter she...

Embodiment 2

[0042] Embodiment two, refer to Figure 4 and Figure 5 , in this embodiment, the getter includes groups of getter sheets equidistantly arranged in the sealed chamber along the axial direction, each group of getter sheets includes at least three getter sheets uniformly distributed in the circumferential direction, and the axis of the sealed chamber Parallel to the plane where the getter sheet is located. In this embodiment, the axis of the sealed cavity is located in the plane where the getter sheet is located. In this embodiment, the getter sheet can be rectangular, or installed on a rectangular On the support plate, the heating device is located in the center of the getter sheet group or sleeved outside the getter sheet group. When it is located in the center, it is an electric heating wire or an electric heating rod. When it is sleeved outside the getter sheet group, it is a spiral Shaped electric heating wire.

Embodiment 3

[0043] Embodiment three, refer to Figure 4 and Figure 6 , in this embodiment, the getter includes groups of getter sheets equidistantly arranged in the sealed chamber along the axial direction, each group of getter sheets includes at least three getter sheets uniformly distributed in the circumferential direction, and the axis of the sealed chamber Parallel to the plane where the getter sheet is located. In this embodiment, the vertical line of the getter sheet is perpendicular to and intersects the axis of the sealed cavity. In this embodiment, the getter sheet can be rectangular, or installed in a rectangular On the bracket plate, the heating device is located in the center of the getter sheet group or sleeved outside the getter sheet group. When it is located in the center, it is an electric heating wire or an electric heating rod. When it is sleeved outside the getter sheet group, it is Helical electric heating wire.

Abstract

The invention provides a getter pump and a movable storage tank using the getter pump. The getter pump comprises a shell, a valve and an air suction assembly, a sealing cavity is formed in the shell,and the sealing cavity is provided with an inlet end; the valve is provided with an air inlet end and an air outlet end, a valve element is arranged in the valve, the air outlet end is connected withthe inlet end of the sealing cavity, and the air inlet end is provided with a connecting device used for being connected with a sealing vacuum device; and the air suction assembly is installed in thesealing cavity and comprises an installation support, a getter and a heating device, the installation support is fixed in the shell and used for installing the getter, the getter is fixed to the installation support, and the heating device is used for heating and activating the getter. The getter pump is used for absorbing residual hydrogen, oxygen, carbon monoxide and other gases, is simple and compact in structure, low in manufacturing cost, convenient and fast to activate, easy and convenient to install and long in service-life, and is suitable for the industrial fields of chemical engineering, new energy, scientific research institutes, vacuum low-temperature tanks, electric vacuum and the like, and the vacuum effect can be maintained for a long time.

Description

technical field [0001] The invention relates to an air suction pump, in particular to an air suction pump and a mobile storage tank using the air suction pump. Background technique [0002] Mobile tank cars and storage tanks are used to transport chemical raw materials. Due to the particularity of chemical raw materials, it is necessary to ensure high thermal insulation of mobile tank cars or storage tanks. In traditional technology, tank cars or storage tanks have two layers, the inner layer is used to store chemical raw materials , the insulation layer is filled between the inner and outer layers, specifically, at least 50 layers of heat insulation layers are wrapped around the outer wall of the inner tank, and the heat insulation layer is usually made of aluminum foil; there is also a method of vacuuming between the inner tank and the outer tank , so as to avoid the heat loss caused by reducing the heat transfer, but affected by the process and materials, the vacuum degre...
