Embodiment Construction
[0035] The invention provides an airtight pulverizer, which includes a sample pulverization tank and a non-contact torque transmission system. As the power source of the pulverizer, the non-contact torque transmission system adopts the principle of non-contact torque transmission to transmit the torque power outside the sample pulverization tank to the sample pulverization tank in a non-drilling direct contact manner, thus providing full gas A solid basis for implementation.
[0036] see figure 2 As shown, the non-contact torque transmission system includes a motor 5 , a magnetic shaft 6 and a magnetic transmission coupling 1 , the motor 5 is connected through the magnetic transmission coupling 1 and drives the magnetic shaft 6 to rotate. Among them, the magnetic transmission coupling 1 is used as a transmission component of the non-contact torque transmission system, and adopts the principle of magnetic coupling to realize the transmission of torque and motion between the m...

Abstract
The invention discloses an airtight pulverizer and application thereof. The pulverizer comprises a sample smashing tank and a non-contact type torque transmission system. The non-contact type torque transmission system comprises a motor, a magnetic rotation shaft and a magnetic transmission coupler. The motor is connected with the magnetic rotation shaft and drives the magnetic rotation shaft to rotate through the magnetic transmission coupler. A shell is arranged outside the magnetic rotation shaft. The lower end of the magnetic rotation shaft extends out of the bottom of the shell and extends into the sample smashing tank. A stirring piece is arranged in the sample smashing tank. The magnetic rotation shaft is connected with the stirring piece and drives the stirring piece to act. The sample smashing tank is connected with the shell of the magnetic rotation shaft in a sealed mode. According to the pulverizer, through the magnetic transmission technology, the external torque transmission efficiency is kept, good sealing, enough power, high efficiency and good effects are achieved when a sample is smashed, operation is easy and convenient, and the airtight pulverizer is suitable for practical use. The gas content of a rock sample can be measured through the pulverizer.
Description
technical field [0001] The invention relates to an airtight pulverizer and its application, especially the application in measuring the gas content of rock samples. Background technique [0002] In many fields such as geology, energy, mining, transportation, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, beauty, environmental protection, etc., there are various fine crushing methods. In many fields, it is necessary to carry out sample crushing under fine, fast, efficient, and environmentally friendly conditions. It has a wide range of application value and promotion significance in scientific research and industrial evaluation such as quality maintenance, green crushing, dust-free treatment, bacterial culture, aseptic operation, gas sample collection, gas metering, component detection, etc. [0003] At present, the main crushing methods on the market include ball milling, planetary, drum, blade, rolling or vibrating sieve...
