Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of liquid nitrogen tanks, in particular to a large-scale liquid nitrogen tank salvaging spoon. Background Art
[0002] Liquid nitrogen is an inert, colorless, odorless, non-corrosive, and non-flammable nitrogen gas that is dissolved in an extremely low temperature environment. Liquid nitrogen is an inert, colorless, odorless, low-viscosity, non-corrosive, non-flammable, and transparent liquid at extremely low temperatures. When it vaporizes, it absorbs a large amount of heat and can cause frostbite. Liquid nitrogen is stored in liquid nitrogen tanks, and when it is needed, a salvage scoop is required to extract it.
[0003] Patent document CN221548409U, a prior art publication, provides a visual salvage device for a liquid nitrogen tank, relating to the technical field of cryogenic storage equipment. The device comprises a salvage rod and a salvage body, the salvage body being disposed at one end of the rod and used to salvage samples from liquid nitrogen; a housing disposed on the rod, the inner cavity of the housing serving as a monitoring space, and a transparent end facing the salvage body; a light source disposed on the inner wall of the housing and located within the monitoring space; and a camera assembly located within the monitoring space, disposed within the inner wall of the transparent body, and capable of detecting through the transparent body. This application improves the current situation where liquid nitrogen vaporization produces a large amount of fog, making it difficult to see clearly.
[0004] However, when using the existing large liquid nitrogen tank salvage scoop, the staff opens the liquid nitrogen tank and then places the salvage scoop inside the liquid nitrogen tank to salvage the liquid nitrogen. However, during the salvage, although the appropriate amount of liquid nitrogen can be salvaged by using salvage scoops of different sizes, the situation inside the liquid nitrogen tank cannot be clearly seen during the salvage process, resulting in an inability to know the amount of liquid nitrogen salvaged. As a result, the staff needs to salvage multiple times to salvage the appropriate amount of liquid nitrogen, thereby affecting the salvage efficiency.
[0005] Therefore, those skilled in the art have proposed a large liquid nitrogen tank salvage spoon to solve the problems raised in the background art. Utility Model Content

[0007] A large liquid nitrogen tank salvage spoon, comprising a handheld unit and a nitrogen filling unit, wherein the handheld unit comprises a storage rod, a screw thread is provided at the top of the storage rod, an adjustment rod is threadedly connected to the top of the storage rod through the screw thread, a weighing hook is fixedly connected to the top of the adjustment rod, a weighing sensor and a battery are fixedly connected to the bottom of the weighing hook, the weighing sensor is fixedly connected to the adjusting rod, an electronic screen is fixedly connected to the top of the weighing hook, and a mounting bracket is fixedly connected to the bottom of the storage rod, and a mounting slot is provided on one side of the mounting bracket;
[0008] The nitrogen filling unit comprises a salvage tank located at one side of the mounting groove, and the outer side of the salvage tank is fixedly connected with a mounting rail.
[0009] Preferably, a handle sleeve is fixedly connected to the outer side of the adjusting rod, and the handle sleeve is made of plastic material.
[0010] Preferably, a connection port is provided on the top of the mounting frame, and the mounting frame is fixedly connected to the storage rod through the connection port.
[0011] Preferably, the inner diameter of the screw mouth is adapted to the diameter of the adjusting rod, and the adjusting rod is a solid structure.

[0013] Preferably, a through opening is provided on the top of the salvage tank, and the salvage tank is made of stainless steel.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The utility model is provided with a weighing hook, an electronic screen and a weighing sensor. When using the liquid nitrogen tank salvage spoon, the staff opens the lid of the liquid nitrogen tank, and then holds the handle sleeve to push the salvage tank deep into the liquid nitrogen tank. At this time, the liquid nitrogen inside the liquid nitrogen tank will enter the opening of the salvage tank. After the salvage is completed, the staff holds the weighing hook. At this time, the weighing sensor will weigh the liquid nitrogen inside the salvage tank and display it on the electronic screen, so that the staff can know the salvaged amount. When the salvaged amount is too much, the staff can pour the excess out of the salvage tank. When the salvaged amount is too little, the salvage tank can be pushed deeper into the liquid nitrogen tank to continue salvaging an appropriate amount of liquid nitrogen. There is no need to take the salvage tank out of the liquid nitrogen tank to know the salvaged amount, so that the staff can salvage an appropriate amount of liquid nitrogen according to the salvaged amount, thereby improving the salvage efficiency.
