It splits splashing scene to be also enough test engineer is allowed to generate psychological shade, how to prevent trouble before it happens just has before glass disappears and boils pipe fragmentation
Safety alarm device simultaneously carries out forced brake as a problem to be solved.
Utility model content
The utility model is at least one defect overcome described in the above-mentioned prior art, is provided a kind of with pressure alarm work(
The kjeldahl apparatus distilling apparatus of energy, disappear the occurrence of boiling pipe fragmentation to avoid high-pressure glass, ensures the safety of experimenter
Experimental enviroment.
The technical solution of the utility model is：A kind of kjeldahl apparatus distilling apparatus with pressure alarm, including
Disappear and boil pipe, vapor conduit, steam oven, vapor tube at one end connection, which disappears, boils inside pipe, other end connection steam oven
Inside further includes to be fixed on to disappear and boils the sealing device of tube opening, fixed on sealing device to distillate fluid catheter, distillate tube at one end
Connection, which disappears, boils pipe, and the other end is connected to disappear and boil outside pipe；
Wherein, pressure detecting and control mechanism, computer control system, the pressure detecting and control mechanism are further included
Pipe top is boiled set on disappearing, computer control system is electrically connected respectively with pressure detecting and control mechanism, steam oven.
In the utility model, when disappearing, to boil overpressure excessively high, and pressure detecting and control mechanism receive signal and send to
Computer control system is simultaneously alarmed, and the detection of simultaneous computer control system control pressure and control mechanism pressure release and steam oven stop
Heating is prevented from disappearing and boils pipe and crush to reduce pressure.
Further, the pressure detecting and control mechanism include probe, pressure control device, pressure sensor, institute
The probe one end stated is inserted into disappear and be boiled in pipe, and other end connection pressure sensor, pressure sensor is connected by signal transmssion line and counted
Calculation machine control system；
Pressure control device one end connection sealing device, the other end connect computer by signal transmssion line and control
System.
The size of probe and pressure sensor can detect pressure, it is direct that pressure control device can experience instantaneous pressure overload
Pressure release is opened, is controlled under normal pressure by computer control system.
Further, the pressure sensor is ceramic pressure sensor.With high resiliency, anticorrosive, wear-resistant, anti-
The characteristic of shock and vibration.Pressure sensor is arranged on to disappear and boil outside pipe, reduces acid and alkali corrosion.
Further, vapor conduit connection steam oven conducting wire, steam oven conducting wire are connected to inside steam oven.Institute
The steam oven stated is connect by signal transmssion line with computer control system.In the utility model, pass through the side of signal transmssion line
Formula is safe and reliable.
Compared with prior art, advantageous effect is：The utility model is for safety existing for current kjeldahl apparatus instrument
Hidden danger is improved, i.e., pressure sensor is added in distillation process, distillation process pressure is monitored into Mobile state, when pressure mistake
Height sends out security alarm sound and instrument is carried out forced brake automatically, passes through the variation of pressure in dynamic pressure monitoring process
Determine that sample ensures the safety of experimentation.
