Embodiment

By specifying technology contents of the present invention, structural attitude, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 to Fig. 5, a kind of cellanalyzer preheating device that technical scheme of the present invention provides comprises titanium alloy container body 1, preheating clamping plate 2, heater 3, temperature sensor, temperature controller, temperature detect switch (TDS) and two above interfaces 6; Said container body 1 is provided with groove, and said heater 3 places in the said groove; Said preheating clamping plate 2 are fixed in said container body 1 sidewall outside surface, and fit with said heater 3; Said temperature sensor is fixed on the said preheating container body wall outer surface, and said temperature controller is electrically connected with said temperature sensor, and said temperature controller is electrically connected with said temperature detect switch (TDS), and said temperature detect switch (TDS) is electrically connected with said heater; Said interface 6 is arranged on the said titanium alloy container body and with container body 1 inside and is connected, and being used to insert the liquid in the container body 1 and with liquid derives in container body.

In embodiment, 4 lockings of said preheating clamping plate 2 usefulness backplates, said backplate 4 is the PTFE plate; Wherein, The PTFE plate adopts the suspension injecting tetrafluoroethylene resin to make through compression molding, uses the made plate serviceability temperature scope of this material very extensively, has very strong corrosion resistivity.In addition; The insulating property of this material are good, high insulating effect, in the present embodiment; Use four blocks of PTFE plates; Thereby entire container main body 1 is surrounded, avoided container body 1 and extraneous direct the contact, played very large booster action thereby make whole invention technical scheme can control temperature flexibly.

Be provided with two heaters 3 at said container body 1 sidewall outside surface, heater 3 is processed heating board, thereby heating board is well contacted with the preheating clamping plate.When heater 3 adstante febres, with the preheating of preheating clamping plate, the preheating clamping plate are again with the said container body 1 of heat transferred, thereby reach the purpose that adds thermal agent.In a preferred embodiment, said heater can directly carry out heat conduction with said container body 1, thereby heat is provided for said container body 1.

In addition, said backplate 4 outsides also surround heat insulation foam, and heat insulation foam has played good heat insulation effect.

One preferred embodiment in, said container body 1 is six spatial structures, is fixed with a preheating end cap 5 at the lower surface of container body 1, the reagent in 5 pairs of container bodies of said preheating end cap 1 has played the effect of insulation equally.In the present embodiment, said interface 6 is arranged on the upper surface and the lower surface of said container body 1.The reasonable setting of interface position, convenient when in inserting the liquid into container body 1 and with liquid, in container body 1, deriving.
