Automatic powder grinding device in anhydrous drying oven

Abstract

The invention discloses an automatic powder grinding device in an anhydrous drying box. The automatic powder grinding device in the anhydrous drying box comprises a drying mechanism and an automatic powder grinding mechanism, wherein the drying mechanism comprises a box body; a circular pipeline is arranged on the outer side of the box body; a gas drier and a vacuum pump are arranged on the circular pipeline; two ends of the circular pipeline communicate to the inner part of the box body to form a drying circular gas circuit of inner gas in the box body; the automatic powder grinding mechanismplaced in the box body comprises a base arranged in the bottom of the box body, wherein a rack is fixedly arranged in the middle of the base, a rotary driving device is fixedly arranged on the base at the back end of the rack, and a rotary disc is rotatably arranged on the base below the front end of the rack; a transmission connecting piece is in transmission connection to a rotary disc is arranged below the base, and the rotary driving device is in transmission connection to the transmission connecting piece; a grinding rod is rotatably arranged on the rack above the rotary disc, a tilt angle mechanism is arranged on the rack, and the tilt angle mechanism drives the grinding rod to carry out tilt angle movement around a connecting rod on the rack.

Description

technical field [0001] The invention relates to an automatic powder grinding device in an anhydrous drying box, in particular to an anhydrous automatic powder grinding device required in infrared sample preparation, and belongs to the field of analysis and test equipment manufacturing. Background technique [0002] Infrared spectroscopy is based on the change of molecular vibration energy level. When the sample molecule is irradiated with infrared light, the chemical bonds or functional groups in the molecule can undergo vibrational absorption. Different chemical bonds or functional groups have different absorption frequencies and will be in different positions on the infrared spectrum. Obtain information about what chemical bonds or functional groups are contained in the molecule. Infrared spectroscopy is an important analytical and testing method in chemical analysis, and it is widely used in the research of organic chemistry, biochemistry, polymer materials, semiconductor...

Problems solved by technology

However, potassium bromide powder is very easy to absorb moisture when exposed to the air, which is not easy to remove and has a strong infrared absorption peak

The infrared powder sample grinding process is a process that is exposed to the air for the longest time. In order to prevent the potassium bromide powder from absorbing moisture in the air during this process, we generally use infrared lamps to bake the ground solid powder, or Grinding is carried out under the infrared lamp environment, but when the sample is taken out from the infrared lamp to the tablet press for tableting, it is a process in which the hot sample encounters cold air, and the sample will absorb water more easily
