Abstract
The utility model discloses a time controller used for the electric heating temperature of a raw material; the controller comprises a detector, a time controller and relevant control cables; the detector is arranged at a material inlet of a heating electric stove, and electrically connected with the time controller by the control cable; the time controller is connected with a control switch indicator of the heating electric stove by the control cable; the time control node of the time controller is: delta t= (P-P')*T/(C*M); the time controller uses an electric element of the detector to detect the position of the raw material; when the raw material enters into the heating electric stove, the detector sends signal to a time relay of the time controller, so as to trigger the time controller to start to count time; and when the counted time reaches the preset time control node, the normally opened switch of the time relay is closed, and continuous heating is stopped. The application of the time controller is good for saving equipment cost, improving electricity and the utilization rate of the raw material, and has the advantages of overcoming visual fatigue and reducing labor intensity.
Description
Technical field
The utility model relates to the temperature control field, relates in particular to a kind of time device that is applicable to the intermediate frequency furnace heating and temperature control.
Background technology
For the raw material electric heating, the present situation of just present working condition adopts the intermediate frequency furnace heating more.If raw material are by intermediate frequency furnace batch (-type) heating, the temperature that raw material are heated by reality often can't satisfy and adds heat request, and the control heating-up temperature is a long-term puzzlement manufacturing personnel's a problem.On the one hand, raw material are prone to the situation of owing temperature and excess temperature, have caused a large amount of raw-material wastes; On the other hand, post bake also will consume many costs and estimate outer electric energy, be that the raw material or the utilance of electric energy all can't satisfy requirements of saving energy.And the method that is conventionally used for the control heating-up temperature has two kinds, the one, carry out intuition judgement, the 2nd by the perusal colour temperature, and control heating time by infrared thermometer.All there is weak point in these two kinds of methods: the raw-material colour temperature of method one perusal, easily form visual fatigue, and the subjective judgement error of the experience that places one's entire reliance upon is also relatively large, and the temperature of detection is accurate inadequately; Though and method two can accurately detect temperature, be subjected to the position limit of heating region, can't detect the heating region actual temperature easily, operability is not high; And require auxiliary facility more, the reliability requirement of system is higher, causes cost higher.
The utility model content
The purpose of this utility model is exactly to overcome the deficiency of above two kinds of schemes and design and propose a kind of low cost, the duration control method and the device thereof of the electric heating temperature that operability and reliability are higher, reach by control, control heating-up temperature exactly heating time.
The purpose of this utility model can realize by following technical solution:
The time-controlling arrangement of electric heating temperature, it comprises checkout gear, time-controlling arrangement and relevant control cable thereof, its checkout gear is positioned at the charging aperture place that adds electrothermal stove, checkout gear is electrically connected with time-controlling arrangement by relevant control cable, time-controlling arrangement is connected with the control switch indicator light of heating furnace by relevant control cable, the time Control Node of time-controlling arrangement is: △ t=(P-P ') * T/ (C * M), in the formula: △ t is raw-material variations in temperature, P is the electrical power of heater, P ' is the electrical piano power loss of heater, T is heating time, and C is for being heated raw-material specific heat, and M is for being heated raw-material quality.
The purpose of this utility model can further realize by following technology solution:
The time-controlling arrangement of aforesaid electric heating temperature, what wherein said checkout gear adopted is optoelectronic switch.
The time-controlling arrangement of aforesaid electric heating temperature, wherein said time-controlling arrangement are the time relay.
Use design of the present utility model, its beneficial effect is embodied in: contrast provides cost savings input by infrared thermometry instrument control heating-up temperature device, has improved operability; Avoided raw-material and owed temperature and excess temperature situation, thereby improved raw-material utilance greatly, reduced raw-material loss; Avoid post bake, saved electric energy, effectively improved utilization rate of electrical; Can control the temperature of raw material heating in enormous quantities,, improve production efficiency than using the colour temperature observation method to reduce labour intensity.
The purpose of the time-controlling arrangement of the utility model heating-up temperature, feature and advantage will be done further to specifically describe in conjunction with respective drawings by a following preferred embodiment, to deepen the understanding to the utility model essence.

Embodiment
The time-controlling arrangement of the utility model electric heating temperature, it comprises checkout gear, time-controlling arrangement and relevant control cable thereof, checkout gear is positioned at the charging aperture place that adds electrothermal stove, checkout gear is electrically connected with time-controlling arrangement by relevant control cable, time-controlling arrangement is connected with the control switch indicator light of heating furnace by relevant control cable, the time Control Node of time-controlling arrangement is: (in the formula of C * M): △ t is raw-material variations in temperature to △ t=(P-P ') * T/, P is the electrical power of heater, P ' is the electrical piano power loss of heater, T is heating time, C is for being heated raw-material specific heat, and M is for being heated raw-material quality.
As shown in Figure 1 and Figure 2, the utility model temperature-time control device, it comprises checkout gear and time-controlling arrangement and relevant control cable (see figure 1).What wherein checkout gear adopted is optoelectronic switch, enter by the light sensation raw material and to add electrothermal stove and Closing Switch, thereby send a signal to time-controlling arrangement, this checkout gear optoelectronic switch GK1 is positioned at the raw material that add electrothermal stove and sends into end, by optoelectronic switch GK1 raw-material position is detected, enter when adding electrothermal stove when detecting raw material, send signal by control cable to the time relay sj 1 of time-controlling arrangement, the triggered time control device picks up counting; And based on conditions such as law of conservation of energy and known heating furnace power, raw material specific heat, raw material quality can calculate obtain heating-up temperature and heating time clear and definite and unique linear relationship.Time-controlling arrangement has been set in advance the heating time of calculating gained, when timing reaches default heating time at that moment, the normal open switch of time relay sj 1 will be closed immediately, send signal controlling and add electrothermal stove and stop heating, and remind the operating personnel to take out heated raw material by status indicator lamp L1 set on the time-controlling arrangement.
More than be to the detailed description of the utility model one embodiment control device from device architecture and two aspects of operation principle, proof can be reached the purpose of the utility model creation fully in the test of reality, has conveniently accurately controlled the heating electric degree.More than be concrete example of the present utility model, this case protection range do not constituted any limitation that all employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
