Description
Technical field
The utility model relates to temperature measurement control system, particularly a kind of temperature detection for Wooden package and Control System for Heat Treatment.
Background technology
Along with the quickening of liberalization of international trade process, trade between various countries exchanges growing, the agricultural harmful organism with Wooden package worldwide the danger of wide-scale distribution and diffusion also day by day increase.Since " anoplophora glabripennis " event occurs in the U.S. in 1998; the problem growing interest is processed to the quarantine of trade goods Wooden package in countries in the world; for this reason; IPPC tissue (IPPC) has been formulated No. 15 plant quarantine measure international standard-" wood package materials management guideline in international trade " (ISPM15) in 2002; its fundamental purpose is unified and standard various countries thermal treatment index, simultaneously also in order to prevent that various countries from borrowing the processing problem of Wooden package that trade barrier are set artificially.In this international standard, regulation thermal treatment must make the timber central temperature reach 56 ℃ of lasting 30mins.China implemented " management method is processed in the quarantine of departure goods Wooden package " in 1 day March in 2005, implemented " management method is processed in the quarantine of imported goods Wooden package " in 1 day January in 2006.So far, China for the Wooden package aspect of commodity comprehensively and international joint.But new standard does not carry out clear and definite regulation to implementation step, environmental facility condition, operation requirements and the detailed technology index etc. of carrying out this standard, thereby the Wooden package of countries in the world processing enterprise difficulty when carrying out this standard is large, often can not guarantee treatment effect, main manifestations has often been detected worm alive by the other side state for the goods Wooden package of outlet, and then has caused processing again, stagnant port, the return of goods, the even generation of the serial consequence such as destruction.
At present, China most of Wooden package manufacturing enterprise is used xeothermic type of heating to heat wood package materials, and the method that employing is imbedded certain thickness wood package materials by temperature-sensing probe is measured and controlled central temperature.But find that in actual use this method has a lot of defects, error is larger.At first, the fibre structure of the wood package materials that temperature-sensing probe inserts is destroyed, makes its temperature conductivity different from other wood package materials, and the temperature measurement result error is larger.Secondly, with dry heat treatment method, timber is heated, the moisture evaporation of timber inside makes the wood surface temperature descend, and has affected hot conduction, thereby has reduced the efficiency of heating surface.
Grasp unified index for the ease of enterprise, fully guarantee treatment effect, most inspection and quarantine departments are that enterprise has set more intuitive and reliable method, usually require enterprise to continue a few hours again after the timber central temperature reaches a specified point, as domestic certain province requires enterprise after kiln temperature (medium temperature) reaches 70 ℃, Wooden package continue is processed 10 hours, during with temperature-sensing probe, the forest timber central temperature is monitored.Facts have proved that the method subjectivity, randomness are larger, lack scientific evidence, wasted a large amount of energy, and, for relatively thicker wooden packing, be difficult to meet processing requirements.The goods of this province's outlet is also often processed halfway problem because of Wooden package and has been caused some trade disputes or controversial issue in importer.
In sum, China lacks a kind of temperature detection for Wooden package and Control System for Heat Treatment effective, easily row at present.
The utility model content
The utility model is for after solving Wooden package being heat-treated, the central temperature measurement result is inaccurate, so that the waste mass energy is difficult to meet the problem of processing requirements, provide especially a kind of temperature detection for Wooden package and Control System for Heat Treatment effective, easily row.
The technical scheme that the utility model taked for achieving the above object is: a kind of temperature detection for Wooden package and Control System for Heat Treatment, it is characterized in that: comprise the temperature measuring set be connected with sense terminals, with the controller be connected with control terminal, sense terminals and control terminal are connected to supervision center by network respectively, and controller is connected to heat treating equipment by multipath solid-state relay and contactor.
The utility model can reach following beneficial effect: make the Wooden package heat treatment process realize robotization, thereby improved work efficiency, reduced energy resource consumption, not only result is accurate, meet processing requirements, and can monitor in real time processing procedure, and autostore deal with data, for inspection and quarantine mechanism provides convenience to the monitoring of Wooden package processing enterprise.
