Technical Field

The utility model belongs to the technical field of general cleanness, concretely relates to nuclear magnetism sample cell belt cleaning device.

Background

Nuclear Magnetic Resonance (NMR) technology is a technology for studying various molecular physical and chemical structures using the physical properties of atomic nuclei and modern electronic science as well as computer technology. The NMR technique can study the relationship between the dynamic processes, molecular structures and biological functions of biological macromolecules and some living tissues, and obtain information that cannot be obtained using other techniques, without destroying the biological sample and maintaining the liquid state. NMR techniques have become one of the most advantageous tools for studying the structure and physical properties of substances in the fields of material science, life science, and molecular science. The nuclear magnetic sample tube needs to be cleaned after each test, the sample tube is a thin tube with the inner diameter of 5mm and the length of 18cm, and one end of the thin tube is sealed, so that the cleaning work is particularly difficult. The sample tube is damaged to a certain degree by adopting manual cleaning and ultrasonic cleaning of the cleaning brush for a long time, the subsequent testing effect is influenced, most of existing cleaners on the market are high in cost and are not easy to operate.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a nuclear magnetism sample cell belt cleaning device of reasonable in design, easy operation, with low costs, not damage the sample cell is provided.

The technical scheme for solving the technical problems is as follows: the utility model discloses a washing tank, including washing tank, baffle, cavity and waste liquid bottle, waste liquid bottle lateral wall top is provided with the exhaust tube, the below is provided with the drain pipe that has the valve, waste liquid bottle bottleneck department is provided with the washing tank, be provided with the baffle in the washing tank, the baffle is cut apart into cavity and lower cavity with the washing tank, lower cavity is linked together with the waste liquid bottle, it has the pipe to be located evenly distributed on the internal baffle of epicoele, the pipe lower extreme passes the baffle and makes this end port be located cavity down, the last cavity and the lower cavity of washing tank are linked together through the pipe, be provided with sealed.

As a preferred technical scheme, a vacuum pump is arranged on the exhaust pipe.

As a preferred technical scheme, the guide pipe is a stainless steel pipe, the outer diameter of the guide pipe is 3mm, the length of the guide pipe is 20cm, and the length of the guide pipe, which is positioned in the upper cavity of the cleaning tank, is greater than the length of the guide pipe, which is positioned in the lower cavity.

As a preferred technical scheme, the bottle mouth of the waste liquid bottle is connected with the ground mouth of the cleaning tank.

The utility model has the advantages as follows:

the utility model discloses a washing tank inner seal is provided with the baffle, and evenly distributed has the pipe on the baffle, is hung upside down on the pipe by abluent nuclear-magnetism sample cell, will bleed through the vacuum pump and make the interior negative pressure environment that forms of washing tank to make the washing liquid wash nuclear-magnetism sample cell, realized that a plurality of sample cell wash simultaneously, the cleaning efficiency is high, the utility model discloses still have easy operation, with low costs, the advantage of environmental protection.
