Description

Technical Field

[0001] The utility model relates to the technical field of liquid helium storage equipment, in particular to a liquid ammonia storage tank capable of preventing leakage and shock. Background Art

[0002] Liquid helium is a colorless, transparent, odorless and tasteless liquid. It is the liquid form of helium and will not solidify under normal pressure. It has the characteristics of superfluidity and superthermal conductivity. It is not only a key material in low-temperature physics research, but also plays a vital role in various high-tech applications. Liquid helium storage tanks are equipment used to store and transport liquid helium. They have high thermal insulation and reliability, and can ensure the effective storage and transportation of liquid helium under various conditions.

[0003] The existing Chinese patent (application number: 202311858481.5) proposes a liquid ammonia storage tank leakage warning system. When ammonia leakage occurs at the tank mouth of the liquid ammonia storage tank and is detected by the detection component, the processing center will display the detection information on the display screen for warning. At the same time, the push-up component moves the detection component close to the ammonia leakage point, and the leaked ammonia is pre-collected and processed to a certain extent, thereby avoiding the continuous increase of ammonia leakage around the liquid ammonia storage tank before the operator performs emergency treatment, facilitating emergency treatment and reducing the losses caused by ammonia leakage.

[0004] Although the above scheme can complete the detection and early warning tasks, there is a gap between the helium detector and the tank mouth seal, and there is an air flow channel between the two, which will affect the detection accuracy.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The utility model aims to provide a liquid ammonia storage tank which can prevent leakage and shock, so as to solve the problems raised in the above-mentioned background technology.

A detection mechanism sealed and connected to the tank is sleeved on the top of the tank. The detection mechanism is provided in multiple groups and is arranged one-to-one with the tanks. Adjacent detection mechanisms are installed by connecting rods. A display processor is installed at the front end of the crossbeam, and the display processor is electrically connected to the detection mechanism.

[0009] In one embodiment, the detection mechanism is displayed in a matrix-type corresponding manner on the display processor. When a leakage occurs in a certain detection mechanism, the human can immediately see the alarm prompt at the matrix display point.

The helium detector communicating with the detection box is installed on the top surface of the detection box. The one-way valve pipe is also installed on the top surface of the detection box. The fan is installed on the bottom surface of the detection box. The bottom of the fan is hermetically connected to the top opening of the sealing bag through the connecting pipe. The bottom opening of the sealing bag is the tightening opening. The inner diameter of the sealing bag is larger than the outer diameters of the sealing plate and the pipe orifice of the tank body.

[0011] In one embodiment, the protection mechanism consists of pipe clamps, side plates, fixing plates, and sealing rings. There are two relatively arranged pipe clamps. The inner diameter between the pipe clamps matches the pipe orifice. Side plates are installed on both sides of the relative ends of the pipe clamps. Threaded holes are provided in the side plates.

The bottom of the vertical section of the mounting rod is connected to the cylindrical rod. Fixing rods are installed on the other circumferential surface of the cylindrical rod. A plurality of fixing rods are arranged in an annular array. The fixing rods are integrally arranged in an arc-shaped rod structure, and their inner walls are attached to the spherical structures at both ends of the tank body. Friction pads are installed on the inner walls of the fixing rods.

[0013] In one embodiment, a base mechanism is installed at the bottom of the tank body. The base mechanism consists of a support seat, a slot, a jack, a locking rod, a screw, a strap, a counterweight, and a positioning hole. An installation groove adapted to the tank body is provided in the middle of the top surface of the support seat. Slots are provided on the top surface of the support seat.

[0032] Working principle:

[0033] During operation, by sleeving the tightening opening 37 of the sealing bag 36 on the pipe orifice 42, the tank body 4 is in communication with the detection box 31, the helium detector 32, the one-way valve pipe 33, the blower 34, and the connecting pipe 35. In case of a leakage, after the helium detector 32 detects the leaked gas, the one-way valve pipe 33 is closed, and the blower 34 is started to pump the helium into the detection box 31 for collection, waiting for the maintenance personnel to arrive for repair.
