Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in detail.

With reference to Fig. 1, portable reactor heating furnace, comprise stainless body of heater 1, heat insulation handle 14 is installed so that mobile in body of heater 1 outside, body of heater 1 inside circumference evenly fixes four strong points 2, the strong point 2 places bearing plate 3 above, bearing plate 3 upper surface evenly fixes four spring stacks 4, heat-barrier material 5 is placed above bearing plate 3, mounting and fixing bracket 6 below bearing plate 3, fixed support 6 is installed lead-in wire deck 7 in order to draw power supply and holding wire, spring stack 4 is placed cast copper electric boiling plate 8, described cast copper electric boiling plate 8 upper surface with reactor bottom bulkhead for model customization, fit completely with reactor.Cast copper electric boiling plate 8 lower end is fixed 2 inlet wire posts and is inserted A10 and draw to introduce power line from the hole of bearing plate 3, electric boiling plate 8 lower surface fixed temperature sensor 9, temperature sensor 9 is also fixed inlet wire post and is inserted B11 draw holding wire from the hole of bearing plate 3, described bearing plate 3, heat-barrier material 5, cast copper electric boiling plate 8, A10 inserted by inlet wire post, B11 inserted by inlet wire post is all detachable unit power line is connected body of heater 1 outside control cabinet 13 with holding wire, described control cabinet 13 inside take single-chip microcomputer as control subject, the signal of collecting temperature sensor 9, power output is regulated by controllable silicon.Body of heater 1 outer footing fixes lifting device 11.Described lifting device 11 supports the whole body of heater of jack-up with the rotation of screw, and body of heater is adjacent to end socket.

Operation principle of the present invention is as follows:

1, apparatus arrangement

Below the reactor of correspondence, put into portable reactor heating furnace, use lifting device 11 to be risen by body of heater 1, by the elastic force of spring stack 4, cast copper electric boiling plate 8 is adjacent to the end socket of reactor, then control cabinet 13 can be energized controls heating.

Lifting device single structure is that 1 screw adds two fixed heads, and it is movable that upper mounted plate perforate tapping thread is used for screw, and outside lower limb under being fixedly welded on body of heater; Bottom plate can bearing or other rotating manners and screw be fixedly linked, and when screw rotates, bottom plate does not rotate; Screw leans on the upper and lower displacement realizing body of heater 1 with the rotation of upper mounted plate.

2, computer heating control

The heating-up temperature of control mode to electric boiling plate that the present invention adopts single-chip microcomputer and controllable silicon to combine controls.Wherein single-chip microcomputer adopts improvement type pid algorithm to realize the accurate control of temperature, ensures the safety of electric boiling plate while ensureing heating; Controllable silicon realizes the step-down process to electric boiling plate power supply by the control signal that trigger receives.

Improvement type pid algorithm basic thought is: when controlled volume and setting value deviation larger time, cancel the effect of integration, in order to avoid make the stability of a system reduce due to integral action, overshoot increase; When controlled volume is close to set-point, introduce integration control, to eliminate static difference, improve control accuracy.Its specific implementation step is as follows:

A) according to actual conditions, artificial setting threshold epsilon > 0;

B) as | error (k) | during > ε, adopt PD to control, can avoid producing excessive overshoot, make again system have and respond faster;

C) as | error (k) | during≤ε, adopt PID to control, to ensure the control accuracy of system.

Algorithm can be expressed as:

$u\left(k\right)=k_p\mathrm{error}\left(k\right)+{\mathrm{\βk}}_i\underset{j=0}{\overset{k}{\mathrm{\Σ}}}\mathrm{error}\left(j\right)T+k_d(\mathrm{error}\left(k\right)-\mathrm{error}(k-1))/T$

In formula: T---the sampling time;

β---the switching coefficient of integration item.

$\mathrm{\β}=\left\{\begin{array}{cc}1& \left|\mathrm{error}\left(k\right)\right|\≤\mathrm{\ϵ}\\ 0& \left|\mathrm{error}\left(k\right)\right|>\mathrm{\ϵ}\end{array}\right.$

Improvement type pid control algorithm flow chart, with reference to Fig. 3.

3, equipment shifts out

Similar with placement process, after cutting off heater power source, the screw turning lifting device 11 reduces body of heater, and portable reactor heating furnace is departed from bottom reactor can be taken away.

Convenient and swift due to what arrange and shift out, and electric boiling plate to be measured reactor end socket make to measure, therefore portable reactor intelligent furnace can reuse all the time, better adapts to industrial production environment.
