The progress and development of structural design of Kjeldahl analyzer
The distiller is an all-glass structure. Distillers can be removed. Steam cleaning is set after each sample is distilled. In the empty steam cleaning process, the cooling water in the cooling pipe can be automatically discharged, the temperature in the pipe can be increased, and high-temperature steam can be used to drive away trace residual ammonia, thereby effectively overcoming the cross contamination of the N15. The center of the distillation system is the rotating body, which is already the core part of the Kjeldahl nitrogen analyzer. Both ends are a pair of mechanical logic components, 'have vent valves, base valves, steam valves, and cooling water valves. This logic element is designed according to the analysis program and performs the respective logic functions in order.
Distillation of each batch of samples takes place in several distillation units before and after, and 25-30 samples per hour can be distilled. Distillation of each sample was carried out continuously for one week in operation. Each sample was steamed for 10-15 minutes to ensure sufficient distillation time. Kjeldahl analyzer in the distillation process, a series of samples of the analysis steps can be carried out in sequence between the successive. With this mode of operation, the amplitude of vapor pressure is small, so that the supply of steam is stable and the energy consumption is small. The Kjeldahl nitrogen distillation unit was rotated for one week, including seven steps of adding alkali, alkali cleaning, upper cooling water, sample distillation, ammonia absorption, unloading the sample cooling water and steam cleaning. Each step is arranged at a specific location.
In summary, the distiller is a key part of the entire Kjeldahl nitrogen analyzer. It plays an important role in the distillation of the power source and the corresponding principle research. In the actual development of the design of the nitrogen analyzer, it is also further An important measure of instrumental analysis and use efficiency. The control of the distiller is not only the appearance of the design, the instrument's personalized and user-friendly operation can save the test operator a lot of time.
The BZ Column Jib Crane known as Post Jib Crane, fixed pillar Jib Crane, fixed pillar rotary arm crane,heavy duty jib crane, cantilever pedestal jib crane,Floor Mounted Jib Crane and pedestal jib crane; it is widely applied to the upper and lower materials, the working procedure and the production line of the workshop. Jib crane in operation, push suspended loads or ring by hand, move towards lifting objects. Wall type swing arm hanging its biggest advantage is that it can be installed directly on the wall or column, or can also be installed on the machine equipment, which does no need to take up any floor space, easy to install.
Features:
1. work within the 360ÌŠ to lift, move and materials handling
2. composed by the vertical shaft, revolving arm, rotating shaft, hoist etc.The bottom of the vertical shaft is fixed on the concrete base.
3. Simple structure, Operate convenience, Turning angle, wide working conditions.
