Abstract
The utility model relates to an efficient compact-type liquid uniform-heating controller which comprises a heating pipe, a Pt resistor, a support and a control circuit and is characterized in that the heating pipe is enwound on the support at two layers; the Pt resistor is arranged at the middle part of the support; and the liquid inlet and the liquid outlet of the heating pipe are positioned at the upper end of the support and both connected with a peristaltic pump, so that two liquids are mixed and driven by the peristaltic pump to uniformly and slowly flow from the liquid inlet to the liquid outlet of the heating pipe. The efficient compact-type liquid uniform-heating controller has the advantages of simple structure, easy operation, high efficiency, high safety and uniform heating.
Description
Technical field
The utility model relates to a kind of liquid-heating system, especially a kind ofly is mainly used in two kinds of even heated liquid heating controllers of liquid.
Background technology
Two kinds of different liquids are under some specified temps, its biochemical reaction is the sensitiveest, in order to realize this specified temp, mainly adopt dual mode at present, the one, be placed on and make its temperature rising in the gas, reach this specified temp, finish biochemical reaction, this mode, the gas heat-transfer coefficient ratio is less, heat time heating time is long relatively, is difficult to realize even heating; The 2nd, be placed on water bath with thermostatic control and heat, this mode, equipment volume is big, heating-up temperature is inhomogeneous, heating power is big, power consumption is big, complex structure, in order to guarantee the constant of water temperature and to strengthen the heat exchange effect and need stir it.Its mode of heating of present disclosed working fluid heater (patent No. ZL200520109719.5) is that electrical heating wire and liquid one coexist in the pipe, the electrical heating wire that this mode heats high temperature directly contacts with liquid, the too high destruction liquid biochemical reaction of local temperature appears easily, so this mode of employing is improper.
This dual mode is difficult to realize liquid is evenly heated, and also is difficult to use in the specific occasion, just can't realize as the occasion that physical dimension is had strict restriction.
Summary of the invention
The utility model is will solve existing liquid heating arrangement complexity, be difficult to realize the evenly technical problem of heating, and the even heating controller of efficiency compact high liquid of a kind of simple in structure, easy to operate, efficient, safety, homogeneous heating is provided.
For achieving the above object, the technical solution of the utility model is: the even heating controller of a kind of efficiency compact high liquid, comprise heating tube, RTD, support, control circuit, be characterized in: the heating tube support twines two-layer, place the RTD of measuring temperature between support, the support upper end is provided with the inlet and the liquid outlet of heating tube, and inlet is connected with peristaltic pump with liquid outlet, makes two kinds of liquid be blended under the effect of peristaltic pump evenly, flow into from the heating tube inlet slowly, flows out from liquid outlet.
Heating tube is to be made of high-temperature resistance plastice pipe, electrical heating wire and heat-shrink tube, the tight two-wire of electrical heating wire and on plastic tube, put heat-shrink tube in the plastic tube outside, and at the uniform velocity mobile with electric iron at the heat-shrink tube outer wall, heat-shrink tube is shunk under the high temperature of electric iron.
Control circuit is made up of temperature control instrument, Power Regulation module, voltage-stabilized power supply and lead, the temperature signal of the RTD surveyed of temperature control instrument wherein, and feed back signal to the Power Regulation module, the Power Regulation module is regulated the electrical heating wire both end voltage according to feedback signal, change its heating power, finish automatic control process.
The beneficial effects of the utility model are:
Heating tube adopt two-wire and around, the magnetic field effect that does not have induced-current to cause has been avoided two kinds of liquid biochemical reactions that therefore cause;
2. earlier heater strip and around plastic tube outer wall, put heat-shrink tube again, contact heat-shrink tube with electric iron, heat-shrink tube is shunk by temperatures involved, and heater strip closely is attached at plastic tube outer wall, and heater strip closely contacts with plastic tube, heat-transfer effect is good, the heating uniformity height;
3. Power Regulation module makes it more accurate according to the heating power of the size adjustment heater strip of temperature;
4. adopt the supply voltage of heating low, handling safety is reliable;
Simple in structure, easily make, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a heating-pipe structure schematic diagram of the present utility model;
Fig. 3 is a heating tube sectional view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Shown in 1, the even heating controller of efficiency compact high liquid of the present utility model comprises heating tube 1, RTD 2, support 7, control circuit as shown in the figure.
Control circuit is made up of temperature control instrument 3, Power Regulation module 4, voltage-stabilized power supply 5 and lead 6, the temperature signal of the RTD 2 surveyed of temperature control instrument 3 wherein, and feed back signal to Power Regulation module 4, Power Regulation module 4 is regulated electrical heating wire 1-2 both end voltage according to feedback signal, change its heating power, finish automatic control process.
As Fig. 2, shown in 3, uniform winding heater strip 1-2 on the heating tube 1, the logical laggard row of power supply of going up heats, and when temperature reached design temperature, heating stopped; In whole heating process, because heater strip 1-2 thickness is the same, its resistance size is consistent, and is identical to the heat flow in heating tube 1 arbitrary cross section, heated liquid uniform temperature unanimity in the pipeline; Signal by the size of temperature and design temperature difference is fed back changes the voltage at heater strip 1-2 two ends, thereby changes its heating power, automatically control.
The making of heating tube 1, two-wire and on high-temperature resistance plastice pipe 1-1 at first around electrical heating wire 1-2, this is the essential condition of even water back 1 liquid, be thermal contact resistance in the middle of reducing, require heater strip 1-2 closely to contact with plastic tube 1-1, in order to realize this characteristic, this patent adopts following measure: plastic tube 1-1 two-wire and behind electrical heating wire 1-2, put heat-shrink tube 1-3 outside, use electric iron at the uniform velocity mobile then at heat-shrink tube 1-3 outer wall, this moment, heat-shrink tube 1-3 shrank under the high temperature of electric iron, made electrical heating wire 1-2 closely and on plastic tube 1-1.
