Abstract
The utility model relates to a novel liquid nitrogen tank, which can effectively solve the problem that the conventional liquid nitrogen tank is high in cost. The technical scheme is that the novel liquid nitrogen tank comprises a tank body, wherein the tank body consists of an inner wall and an outer wall, wherein a cooling cavity is formed between the inner wall and the outer wall; a liquid inlet pipe is arranged at the lower end of the cooling cavity; a gas outlet pipe is arranged at the upper end of the cooling cavity; a vertical rotating rod is arranged in the center in the tank body; a plurality of fixed disks are arranged on the rotating rod in sequence in a sleeved mode; the upper end of the rotating rod is placed in the center of the fixed disk at the upper end of the tank body; and a sealing cover is arranged on the tank body. The novel liquid nitrogen tank is simple in structure and convenient to use; and the using cost is reduced.
Description
Technical field
The utility model relates to biological storage device, particularly a kind of Novel liquid nitrogen tank.
Background technique
With liquid nitrogen cryopreservation cell be the conventional technology of the research field such as medical science, biology, domestic hospitals will hold cryovial conventionally in pail at present, then pail is hung in liquid nitrogen container peripheral wall, the general practice is in liquid nitrogen container, to be full of liquid nitrogen now, cause the consumption of liquid nitrogen greatlyr, user cost is higher.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of Novel liquid nitrogen tank, can effectively solve the higher problem of existing liquid nitrogen container user cost.
The technological scheme of its solution is, comprise tank body, tank body is made up of inner layer wall and outer wall, between inner layer wall and outer wall, have cooling chamber, there is liquid inlet pipe cooling chamber lower end, and there is steam outlet pipe upper end, in tank body, vertical dwang is equipped with at center, on dwang, be set with successively multiple fixed trays, the upper end of dwang is placed in the positioning disk center of tank body upper end, has sealing cover on tank body.
The utility model is simple in structure, easy to use, has reduced user cost.
Accompanying drawing explanation
Fig. 1 is main TV structure sectional drawing of the present utility model.
Fig. 2 is the plan view of the utility model positioning disk.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1, Fig. 2, the utility model comprises tank body, tank body is made up of inner layer wall 1 and outer wall 2, between inner layer wall 1 and outer wall 2, have cooling chamber 3, there is liquid inlet pipe 4 cooling chamber 3 lower ends, and there is steam outlet pipe 5 upper end, in tank body, vertical dwang 6 is equipped with at center, on dwang 6, be set with successively multiple fixed trays 7, the upper end of dwang 6 is placed in positioning disk 8 centers of tank body upper end, has sealing cover 9 on tank body.
In order to guarantee using effect, the lower end of said dwang 6 is fixed on tank body through bearing, guarantees the flexibility of its rotation.
The fixing rod that said positioning disk 8 is three uniform arrangements forms, and its outer edge surface forms a circle.
When the utility model uses, fixed tray is sleeved on dwang, upper end is fixed dwang upper end through positioning disk, in cooling chamber, carry liquid nitrogen through liquid inlet pipe, carry out the biological sample on cooling fixed tray through cooling chamber, can greatly reduce the use amount of liquid nitrogen, reduce user cost.
The utility model is simple in structure, easy to use, has reduced user cost.
