Description
Technical field
The utility model relates to a kind of temperature balancing device, in particular, relates to a kind of device for balancing the fluctuation of PID heter temperature.
Background technology
In a lot of field, we need to carry out temperature control to fluids within pipes medium, majority of case needs the temperature stabilization of fluids within pipes medium in some definite values, now often adopt PID temperature control technology, realized the automatic adjustment of heater power by the automatic temperature-controlled table of PID, thus medium temperature is stabilized near setting value.But due to the limitation of PID control technology self, and be subject to the impact of environment residing for pipeline, in pipeline, the temperature of flow media can not keep an absolute definite value, but present the trend fluctuated up and down around setting value, the amplitude of fluctuation is relevant with concrete control mode and specific environment situation, often have the wave amplitude of positive and negative 1 degree at least, even larger.Needing the occasion of accurate temperature controlling, this temperature fluctuation is unacceptable, and such as, in plastics-production industry or laboratory accurate temperature controlling occasion, the fluctuation that temperature is very little just may cause the decline of product quality or the uncertainty of experimental data sharply to increase.Traditional way after PID well heater, installs Water Tank with Temp.-controlled or oil groove carries out further temperature constant, or directly add hot fluid by Water Tank with Temp.-controlled or oil groove.Thermostatic oil bath, tank realize high (± 0.001 DEG C) water temperature of precision and Oil-temperature control by the heating of special precision, cooling, thermometric, control assembly, and external pipe fluid flows through Water Tank with Temp.-controlled, oil groove by coil pipe.
Cross thermostatic oil bath or tank to realize accurate temperature controlling and face the problem that equipment takes up space, cost is high, these problems of powerful Water Tank with Temp.-controlled or oil groove are more outstanding, and the water of Water Tank with Temp.-controlled, oil groove and oil are often in fixed space, external fluid needs by the just heat exchange of special coil pipe, installs inconvenient.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of device for balancing the fluctuation of PID heter temperature is provided, this device is without the need to external power source and power input, the self-poise of temperature is realized by the mixing of fluid self, there is structure simple, easy to use, the advantages such as cost-saving good balance effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of device for balancing the fluctuation of PID heter temperature, described device is made up of cylindrical mixing chamber, wherein one end of described mixing chamber is provided with fluid outlet, the position, upper, middle and lower of described mixing chamber is respectively arranged with connecting hole, described connecting hole is connected with the isocon one end being wrapped in mixing chamber outer wall respectively, the other end of described isocon is connected with fluid input port, and described mixing chamber is also provided with thermopair interface.
Described mixing chamber and isocon are all made of metal.
Described mixing chamber and isocon are made by copper material.
Described connecting hole is elliptical openings.
Described connecting hole is connected by welding manner with isocon
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1, three isocons of the present utility model are all wrapped on mixing chamber, by the heat exchange of isocon and mixing chamber outer wall, realize the first time balance of temperature fluctuation.
2, the utility model mixing chamber cavity volume is greater than the flow in the cycle of fluctuation of fluid temperature (F.T.), and in mixing chamber, fluid, through fully mixing, by convection current and heat conduction, makes periodic temperature fluctuation greatly reduce.
3, three isocons three positions connections in mixing chamber upper, middle and lower respectively in the utility model, flow approximately equal in three isocons.Three road fluids enter mixing chamber by diverse location, strengthen the disturbance of fluid in mixing chamber, thus strengthen equalized temperature effect.
4, in the utility model, three isocons are connected with the connecting hole of mixing chamber by welding manner, and connecting hole ovalize, fluid is approximate enters mixing chamber from tangential direction, thus forms eddy current in mixing chamber, strengthen mixing effect of fluid, thus strengthen equalized temperature effect.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 to Figure 3, a kind of device for balancing the fluctuation of PID heter temperature, described device is made up of cylindrical mixing chamber 1, wherein one end of mixing chamber 1 is provided with fluid outlet 7, mixing chamber 1 is respectively arranged with top connecting hole 2, middle part connecting hole 3 and bottom connecting hole 4, these three connecting holes are communicated with by welding manner with three isocons 5 respectively, soldering opening ovalize; These three isocon 5 sectional areas are identical, and length differs, and three isocons 5 are spirally wrapped around on the outer wall of mixing chamber 1, and linking together with fluid input port 6 of final convergence, in addition mixing chamber 1 is also provided with thermopair interface 8.
When the utility model is specifically implemented, three same cross-sectional are long-pending, unequal three streams of length by being divided into by three isocons 5 after fluid input port 6 for fluid.Three isocons 5 are respectively by the internal cavities (isocon 5 end and mixing chamber 1 radius near normal) of connecting hole 2,3,4 " incision " mixing chamber 1 on mixing chamber 1, and fluid exports through fluid outlet 7 after mixing in mixing chamber 1.
As shown in Figures 4 to 6, experiment condition is: discharge is 80L/h, PID controls electric heater (phase-shifting trigger, set water temperature is 39 degrees Celsius), the tap water of 8 degrees Celsius is heated, Fig. 4 is the change curve of water temperature when not using any device, and the maximum amplitude that visible water temperature fluctuates up and down near 39 degrees Celsius reaches 2 DEG C even higher; And in Fig. 5 and Fig. 6, after being this device of 0.25L or 0.5L when the volume installing mixing chamber 1, water temperature upper and lower fluctuation range near 39 degrees Celsius significantly reduces and tends to be steady, after visible employing the utility model device, temperature fluctuation amplitude can reduce greatly, Be very effective.
