The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Description of reference numerals is as follows:
1---combustion chamber 2---wire lath
3---chamber walls 4---igniting pin
5---liquefaction tracheae 6---flame detector
7---temperature setting module 8---knob
9---indicator lamp 10---rotary switch
11---power switch knob 12---pipeline
13---lead
As shown in Figures 1 to 4, this far infrared ironing board prewarming system mainly by in the screed casing four independently the igniting assembly of the air inlet on combustion chamber, the screed casing and a control device are formed.The square cavity that combustion chamber 1 is made up of metal derby, its lower end is an opening, Open Side Down when being fixed on the screed side by side, the combustion medium that is made of wire lath 2 is positioned at its bottom, on the both sides of chamber wall 3, respectively be placed with igniting pin 4, liquefaction tracheae 5 and a flame detector 6, igniting pin 4 is used for automatic igniting, liquefaction tracheae 5 is used to provide gas, the temperature when flame detector 6 is used to survey burning.The combustion chamber links to each other with liquefied gas bottle by pipeline, pipeline is provided with electromagnetic valve, the place of process also has a gas mixer chamber simultaneously, temperature setting module 7 is installed between flame detector and the control device, this module is a square, the knob 8 that a band dial is arranged on its side, be used for setting the heating maximum temperature, the other both sides of module connect flame detector and control device respectively, control device is made up of the control panel and the integral control circuit that are fixed on the screed, is used to control flame detector 6, the light a fire switch of pin 4 and electromagnetic valve automatically.
As shown in Figure 4, the control panel of control device is provided with eight circular indicator lamps 9, and each four on left and right both sides also are provided with eight rotary switches 10, topmost a knob is a power switch knob 11, and there is the pipeline 12 and the lead 13 that is connected power supply that connects liquefied gas the bottom surface of control box.In addition, also be provided with temp controlled meter on the control panel, this temp controlled meter respectively with flame detector, integral control circuit links to each other with height temperature control power supply, integral control circuit respectively with the igniting pin, flame detector links to each other with electromagnetic valve, the infrared rays that flame detector sends by the temperature of heating just can be measured heating-up temperature, control panel is provided with workspace working station indicator and control corresponding button, also be provided with alarm and the toggle switch that is used to set predetermined temperature, when temperature has surpassed our setting range, alarm then sends alarm sound, press button is used for being provided with default temperature, be divided into high temperature and low temperature, because control circuit and control panel adopt prior art to realize, therefore just repeat no more here.
The control flow of this system is: open the heating power supply switch--------demonstration of＞temperature--------control of＞temperature----------＞concentrate electrical equipment control----------＞automatic ignitor is opened----------＞open burnt gas valve-------＞work, electric storage means provides operating voltage for electromagnetic valve, when electricity passes through electromagnetic valve, electromagnetic valve is opened air supply valve, gas is passed through, enter mist, and then to combustion chambers burn, when temperature is higher than setting, relay is stopped power supply, make the closed electromagnetic valve gas port,, reach the auto extinguishing effect also with regard to burn-out.The present invention utilizes electrical equipment control to light a fire automatically, does not have the danger that causes scald because of artificial igniting, in the middle of the basic thermal treatment zone jack is being arranged, and when moving this plant equipment, stretches by iron chains and to mention heater surface.
This system mainly utilizes burning of gas such as oil liquefied gas, natural gas to produce infrared rays, and the principle by infrared radiation heats screed.Have lack automatic igniting, blowout protection when flame-out (meet when normally using can light a fire again automatically), the defencive function of dying, heat time heating time, the temperature difference evenly, characteristics such as not fragile.The tradition preheating method needs 20～40 minutes heat time heating time, and this system only needs about 10 minutes.Its functional characteristics is as follows:
1. adopt inexpensive liquefied gas to act as a fuel, thereby reduce engineering cost;
2. utilize advanced surface combustion technology, adopt wire lath as combustion medium and heater element, long service life, sufficient combustion, radiation efficiency height;
The ability of 3. anti-mechanical shock and thermal shock is strong;
4. the infra-red heat penetrating power of Chan Shenging is strong, is easy to be absorbed by bituminous concrete;
5. lack heat time heating time, the heating road surface is not turned black burnt;
6. as required, can regulate thermal treatment zone length;
7. can light a fire blowout protection, temperature control automatically;
8. can resist five to six grades of fitful winds.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the present invention or akin technical scheme is all within its protection domain.
