Description
Technical field
The utility model relates to a kind of heater, and especially relating to a kind of employing temperature control system provides pre-warmed heater for cleaning fluid on the automatic clinical chemistry analyzer fast.
Background technology
Biochemical Analyzer need be simulated body temperature usually, tests under 37 ℃ of temperature, for guaranteeing accurately measurement result, will carry out temperature control effectively to reaction tray.Reaction cup all needs to clean effectively after each the use, if the temperature of cleaning fluid is lower, will the isoperibol of reaction tray be exerted an influence, thereby influences measurement result.So before cleaning fluid enters the reaction tray system, need preheat earlier, cleaning fluid more helps the cleaning performance of reaction cup when temperature is higher in addition.
The existing device that is used for the cleaning fluid heating comprises workpiece preheating block container, cover plate, heating rod, temperature sensor, overheat switch etc.; heating rod and temperature sensor and bridge welding are connected together; as an integral installation on the workpiece preheating block container, overheat switch be installed in cover plate above.If heating rod or temperature sensor have problem, need to change whole cover plate assembly, thereby have the relatively poor defective of maintainability; Overheat switch exposes in addition, and installation and use are all unreliable.
The heater that has in the market improves at such scheme, cover plate is fixed on the workpiece preheating block container, heating rod fixed muffle and temperature sensor fixed muffle and cover plate are welded as a whole, like this, heating rod just can be safeguarded separately with in temperature switch is installed in different fixed muffles respectively.But this type of heater is slow, the ineffective defective of ubiquity firing rate still.
Summary of the invention
The utility model proposes a kind of nonstorage calorifier that is used for cleaning fluid, solve still slow, the ineffective technical problem of ubiquity firing rate of existing heater.
The utility model adopts following technical scheme to realize: a kind of heater that is used for cleaning fluid, and it comprises: an end face is provided with inlet, and the other end is provided with the preheating tube of cover plate, on this cover plate liquid outlet is set; Be arranged on heating rod, temperature sensor and the overheat switch of preheating tube inside; Wherein, the connection of the lateral surface of heating rod is provided with some fin, and some fin are respectively that arrangement setting is evenly dispersed at the center with the heating rod.
In addition, at preheating tube lateral surface heat-insulation layer is set, wherein, heat-insulation layer is the drum of sealing.
Wherein, the through hole that an end face setting of heat-insulation layer provides inlet to pass through, the other end is provided with provides temperature sensor and overheat switch to be inserted into two through holes of preheating tube inside respectively.
Heater of the present utility model is provided with heat radiating fin structure in preheating tube inside, improved the firing rate of heater greatly, and skin increases heat-preservation cotton, reduced thermal loss, heat utilization ratio is high and improved operating efficiency, has advantage of simple structure.

Embodiment
As shown in Figure 1, for an end face of the preheating tube 1 of drum is provided with an inlet 11, the other end is provided with the cover plate 12 with 1 sealing of preheating tube, and this cover plate 12 is provided with provides the liquid outlet 121 that liquid flows out in the preheating tube 1; Between preheating tube 1 inner space and cover plate 12, be provided for heating rod 21, temperature sensor 22 and overheat switch 23; and be connected in heating rod 21 lateral surfaces; with heating rod 21 is some fin 24 of the outside evenly distributed setting in center, fin 24 is enclosed in the inside of preheating tube 1 by cover plate 12.
In conjunction with shown in Figure 2; a heat-insulation layer 3 that reduces heat and air transmitted in the preheating tube 1 also is set in the outside of preheating tube 1; this heat-insulation layer 3 adopts the heat-preservation cotton made; profile also is an O-ring tubular structure; through hole is set on the one end provides the inlet 11 on the preheating tube 1 to pass through insertion; two through holes 31 and 32 are set on the other end, are respectively temperature sensor 22 and overheat switch 23 the insertion mouth that is inserted into preheating tube 1 inside position is provided.
Heat-insulation layer among Fig. 23 is installed on the preheating tube 1 among Fig. 1, has promptly constituted the heater of present patent application, its generalized section as shown in Figure 3.In conjunction with shown in Figure 4, can find out clearly that some fin 24 are that the inside that is arranged at preheating tube 1 is outwards evenly dispersed at the center with heating rod 21.
In conjunction with shown in Figure 5, the temperature control system that constitutes by controller, PWM drive circuit, heating rod 21, temperature sensor 22 and overheat switch 23.Heating rod 21 is by the PWM drive circuitry, initial period continues to heating rod 21 power supplies, heating rod 21 heating quantities of heat given up, fin 24 is rapidly the heat transferred cleaning fluid, after the rinse liquid temperature of preheating tube 1 inside reaches a dynamic equilibrium, the PWM drive circuit can be adjusted into the discontinuous power supply pattern automatically, keeps preheating tube 1 temperature inside balance.Temperature sensor 22 is used for the actual temperature of real-time monitoring preheating tube 1 inner cleaning fluid, if temperature is on the low side, the PWM drive circuit can increase the conduction time of discontinuous power supply pattern, and its temperature is raise; On the contrary; if the temperature of preheating tube 1 internal liquid is too high, when reaching the protection temperature of overheat switch 23, protection switch 23 directly cuts off the power supply of heating rod 21; fall back in the normal range (NR) up to preheating tube 1 internal temperature, protection switch 23 is connected the power supply circuits of heating rod 21 once more.Therefore, cleaning fluid through heating fast, flows out from liquid outlet 121 in preheating tube 1 from preheating tube 1 inside of inlet 11 inflow preheating apparatus.
To sum up, temperature control system of the present utility model have fast the inner cleaning fluid of preheating tube is heated to predetermined stable, high efficiency.And temperature control system is a closed-system, and the course of work is safe and reliable.In addition, the heat transferred that can fast heating rod be produced at some fin of heating rod arranged outside and with the cleaning fluid generation heat exchange of preheating tube inside, the preheating speed who further accelerates cleaning fluid; And the heat-insulation layer that is arranged at preheating tube outside has reduced the thermal loss that the heat exchange of preheating tube and air produces, and helps improving heat utilization ratio, and the operating efficiency of the utility model heater is provided.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
