Description
Technical field
The utility model relates to counteracting tank in a kind of microwave dissolver, relates in particular to the pressure relief of this counteracting tank.
Background technology
The seal-off pressure microwave dissolver is being widely used in the pre-treatment of analytic sample in the assay laboratory.The seal-off pressure counteracting tank is the important accessory in the microwave dissolver.Analytic sample adds after solvent packs in the counteracting tank, counteracting tank is placed in carries out microwave heating in the microwave dissolver, sample in the heating process in the tank body and solvent issue biochemical reaction in the radiation of microwave energy, produce a large amount of gases, because counteracting tank is airtight, gas has formed pressure in jar.
Instrument is under normal operation, and jar internal pressure is subjected to the monitoring and the control of instrument, thereby assurance digestion process safety is carried out.If instrument goes wrong, robot control system(RCS) is malfunctioning, and following two kinds of unsafe conditions then can take place:
The first, because automatic control is malfunctioning, the pressure in the airtight digestion jar has lost control, causes a jar internal pressure constantly to rise, and when pressure rises to when exceeding the intensity that the counteracting tank material can bear, counteracting tank will burst.
The second, instrument can operate as normal and since jar in a sample and a solvent uncertain chemical reaction takes place, moment produces a large amount of gases, and the counteracting tank internal pressure is increased suddenly, causes instrument to lose control ability and causes bursting of counteracting tank.
The lighter that bursts of counteracting tank damages instrument, and weight person jeopardizes personal safety.For this reason, how preventing the generation of above situation, is the matter of utmost importance that domestic and international production firm must consider.
As seen from Figure 1: the way that prior art solves generally adopts bursting membrane to blow brokenly the pressure release technology, but it is malfunctioning suddenly that this structure can only solve in normal digestion process the instrument automatic control function, cause to press constantly in the counteracting tank and rise, when pressure rises to the intensity that can bear above bursting membrane 8, the gases at high pressure that bursting membrane is constantly risen blow brokenly and pressure release, thereby can avoid bursting of counteracting tank.If but meet the unknowable sample of some chemical property in digestion process paroxysmal chemical reaction takes place, moment produces a large amount of gases at high pressure makes instrument out of hand, though this moment, bursting membrane blew brokenly, but a large amount of gases at high pressure have little time to release from pressure release passage 9 for the moment, cause unlimited increase of pressure in the vapor tight tank and burst counteracting tank.Among the figure: blowdown valve 1, gland bonnet 6, bursting membrane chamber 7, bursting membrane 8, pressure release passage 9, gland bonnet shirt rim 10, molten sample cup 11, protective sleeve 12, jar frame 13, sample solubilizer 14.
Summary of the invention
The utility model technical issues that need to address have provided a kind of closed microwave counteracting tank that has the pressure release ring, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: blowdown valve, gland bonnet, bursting membrane chamber, bursting membrane, pressure release passage, gland bonnet shirt rim, molten sample cup, protective sleeve, jar frame, sample solubilizer; Also comprise: a pressure release ring that is placed between gland bonnet and jar frame has the pressure-bearing circle at pressure release ring periphery; A pressure release ring cavity design is at the jar top of the trellis; Fixedly connected with the pressure release ring in the top that pressure release ring fixed cover passes jar frame.
Compared with prior art, the beneficial effects of the utility model are: the counteracting tank that causes in the time of can avoiding abnormal conditions take place bursts.
Description of drawings
Fig. 1 is a prior art counteracting tank structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: blowdown valve 1, gland bonnet 6, bursting membrane chamber 7, bursting membrane 8, pressure release passage 9, gland bonnet shirt rim 10, molten sample cup 11, protective sleeve 12, jar frame 13, sample solubilizer 14; Also comprise: a pressure release ring 5 that is placed between gland bonnet 6 and jar frame 13 has pressure-bearing circle 4 at pressure release ring 5 peripheries; Pressure release ring cavity 3 designs are at jar frame 13 tops; Fixedly connected with pressure release ring 5 in the top that pressure release ring fixed cover 2 passes jar frame 13;
The pressure-bearing circle 4 of described pressure release ring 5 peripheries is structures of complete ring of a circle or part ring;
Being connected between described pressure release ring 5 and the pressure release ring fixed cover 2 is by being threaded.
Pressure release ring fixed cover 2 passes jar frame 13 top-portion apertures that design has a pressure release ring cavity 3 and pressure release ring 5 by being threaded in the utility model, and a pressure release ring and a jar frame are fused.With the bursting membrane 8 bursting membrane chamber 7 of packing into; gland bonnet 6 is covered molten sample cup 11; to build the molten sample cup of lid then and go into protective sleeve 12; above device is put into a jar frame 13; the gas bleed valve 1 that will have the passage that loses heart passes pressure release ring fixed cover 2 and enters bursting membrane chamber 7; compress bursting membrane 8 by screw thread, block the passage 9 that loses heart, make molten sample cup inner chamber form airtight.
Principle of work of the present utility model is: in microwave heating process, if sudden chemical reaction takes place in sample, moment can produce a large amount of gases at high pressure in airtight molten sample cup 11 chambeies, bursting membrane 8 blown brokenly open the passage 9 that loses heart, but because a large amount of gases of instantaneous expansion have little time to let out away from narrow disappointing passage 9 quickly, cause the closed chamber internal pressure to raise, promote gland bonnet 6 roof pressure pressure release rings 5.When roof pressure power surpasses the bearing strength of pressure release rim bearing trim ring 4 settings; pressure release rim bearing trim ring 4 breaking releasings; pressure release ring 5 is headed in the pressure release ring cavity 3; rise in the shirt rim 10 of gland bonnet 6 simultaneously; the position of rising this moment has lost the protection of molten sample cup 11 and protective sleeve 12; so gases at high pressure blow brokenly gland bonnet shirt rim 10 immediately, a large amount of gases at high pressure were released from blowing cut in moment, thereby avoid bursting of whole counteracting tank.
