Problems solved by technology

The advantage of this method is that there is no damage to the NMR sample tube and the cleaning speed is fast; the disadvantage is that the cleaning of stubborn stains is not thorough, and the amount of rinsing solvent is very large
At present, there are relatively few types of NMR sample tube cleaners on the market, and those that can be seen in the domestic market are basically designed according to the principle of vacuum negative pressure. The disadvantages of this cleaner are obvious as mentioned above. Promotion is not good

Embodiment 1

[0020] A hand-held portable nuclear magnetic resonance sample tube high-pressure cleaner, including a flushing nozzle 1 made of stainless steel, a splash guard 2 made of stainless steel, and a body 7 made of plastic, wherein one end of the conversion joint 3 is a quick-plug interface, The other end is the external turnbuckle interface. The tail of the flushing nozzle 1 is inserted into the quick-plug interface of one end of the conversion joint 3. The other end of the conversion joint 3 is connected to the external turnbuckle interface and the reducing screw 4. The other end of the reducing screw 4 is Link to each other with the fuselage 7 by connecting the screw button 5; 1# power cord 11, 2# power cord 14; one end of the connecting joint 6 is connected with the screw buckle 5, and the other end is connected with the quick plug interface 8, and the pressurized water (gas) is connected to the connecting pipe 8. ) to the connection joint 6, one end of the 1# power line 11 is co...

Embodiment 2

[0025] Gas connection flushing process: first insert the flushing nozzle 1 into the NMR sample tube, then connect the external connecting pipe 10 to the nitrogen gas source, turn on the switch 15 to supply power to the micro pressure pump 9, and then the micro pressure pump 9 pumps out the gas under pressure. The gas passes through the pipeline 8, the connecting joint 6, the connecting screw 5, the reducing screw 4, the conversion joint 3 and the flushing nozzle 1, and reaches the bottom area of ​​the NMR tube. Due to the large air flow, the water in the NMR sample tube will be carried by the air flow. out to achieve the purpose of drying.

Abstract

The invention discloses a handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device, and belongs to the technical field of a high-pressure cleaning device. The handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device comprises a washing spray head and a machine body, wherein the tail of the washing spray head is inserted into an adapter; the adapter is connected to a variable-diameter screw which is connected to the machine body by a connecting screw; a connecting joint, an internal connecting pipe and a miniature pressure water pump are arranged in the machine body; one end of the connecting joint is connected to the connecting screw; and the other end of the connecting joint is connected to a pipeline; the other end of the pipeline is connected to one end of the miniature pressure water pump; the other end of the miniature pressure water pump is connected to an external connecting pipe; the other end of the external connecting pipe is connected to a water source or an air source; the machine body is provided with a handle; a power supply is arranged in the middle of the handle; one end of a power line No.1 and one end of a power line No.2 are connected to the power supply. The handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device is suitable for sample tubes with various diameters, is convenient to operate , has no special requirements on operation conditions and has strong universality; and as water serves a cleaning medium, the handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device is green and environmentally-friendly and has powerful generalizability.

Description

technical field [0001] The invention belongs to the technical field of high-pressure cleaning devices, and in particular relates to a hand-held portable high-pressure cleaner for nuclear magnetic resonance sample tubes. Background technique [0002] At present, large-scale scientific research instruments are rapidly popularized in national universities, research institutes and high-tech enterprises. For example, high-resolution nuclear magnetic resonance technology is developing rapidly. They are widely used in chemistry, biology, materials, electronics, medicine, food, pharmacy and pathology play an irreplaceable role. In the past two decades, liquid high-resolution NMR spectrometers have been widely used in universities, scientific research institutes, customs, drug regulatory departments, pharmaceutical companies and related enterprises and institutions. A large number of NMR sample tubes need to be cleaned after testing. Due to the small inner diameter, long length and ...
