The digester plays a very important role in the Kjeldahl analysis of protein samples, because the quality of the digestion during the detection process is directly related to the accuracy of the determination. Therefore, the protein of the sample must be determined accurately. Content, then the prerequisite is to choose a suitable digester.
Generally speaking, the factors influencing the digestion quality of the digester are mainly the effective control of the temperature change, the consistency of the sample pore temperature and the constancy of the temperature inside the blast furnace cavity. Therefore, these points need to be paid attention to in the digester work, in the choice of digestion In the furnace, the following indicators need to be examined:
1. Whether the digester program has a temperature increase control to effectively control the temperature change process is to avoid digestion is an effective way to sample the wall, so in general in order to ensure the effect, in the process of digestion, the digester is required to be able to control the temperature according to need, And if there is a program temperature control can effectively meet the needs, so one of the first important indicators of the digestion furnace is whether the digestion furnace program has temperature control.
2. The thickness and material of the digester insulation material are published at a constant temperature. Small fluctuations ensure that each sample has a consistent digestion time, and effective insulation measures can increase the consistency of the temperature in the furnace cavity because the insulation material is not closed or It is impossibilities to be single and thin, then it is bound to cause temperature instability. Therefore, in order to meet the needs of temperature stability, digester equipment generally has a thick insulation layer, so the thickness and material of the digestion furnace insulation material is also a very important inspection index. .
3. Reasonable choice of heating body and heat carrier The choice of heating body and heat carrier is also very important, because it is related to the speed and effect of temperature increase. In general, the choice of heating body and heat carrier of digester is based on the needs of the experiment and the user's To choose from the requirements, only the proper heating body and heat carrier can be selected to achieve the good results of the instrument.
4. The last inspection indicator of the safety protection function of the digester is the safety protection function of the digester. Only perfect safety protection functions can ensure the smooth operation of the test operation, prolong the service life of the instrument, and protect the personal safety of the operator. Therefore, the safety protection function of the digester is also a key consideration. Generally, it is to see if the digester has temperature stability protection, over-current and short-circuit protection.
Rail transportation of inclined shafts is an integral part of mine transportation and an important link in safe production of coal mines.According to the requirements of the coal mine safety regulations, the safety measures of "one slope and three gears" must be set up in the transportation of inclined shafts, namely the car barrier, the automatic anti-sports car device and the vehicle blocking device.Over the decades, the number of casualties caused by accidents involving sports cars in mines has become a "stumbling block" for the development of coal production.Stopper is installed at the bottom of the well head to stop the car because of out of control and decline of machinery, divided into two kinds, often and often closed can effectively stop car fall, avoid the occurrence of major accidents
