Abstract

The utility model relates to a time controller for an oil combustion boiler, which is a device which can carry out control for oil combustion boilers. An indicator lamp, a digital display temperature controller and a transfer switch are arranged on the door plate of a tank body, a power switch, a wire running groove for a cable, a relay wire connecting terminal and a TS signal processing circuit are arranged in the tank body, and a time controller is also arranged on the panel of the tank body. The utility model has the advantages that the time controller is matched with an oil combustion boiler to be used, and is directly operated without the need of stokers; the starting-up and the stopping time of boilers can be set according to the requirements in advance, labor is saved, and the automatic degree is high.

Description

The oil burning boiler time controller

The utility model relates to a kind of equipment that oil burning boiler is controlled, and is a kind of oil burning boiler time controller specifically.

General boiler all will have the process special training, the fireman who passes the examination work on duty, because the influence of operative employee's factors such as technical merit, the boiler combustion situation is perfect not to the utmost, and cause very big manpower to waste, for example having when satisfying morning working just boiling water, fireman must shift to an earlier date a period of time sometimes starts working.

The utility model is in order to overcome the deficiency in the above-mentioned technology, to save manpower, proposing a kind of oil burning boiler time controller; do not need the fireman directly to go operation; can be as required, the start of pre-set boiler and downtime, control the start and the shutdown of oil burning boiler by the oil burning boiler time controller.

The utility model purpose is realized by following technical scheme: this oil burning boiler time controller, on the casing door-plate, adorn power supply indicator, combustor relay indicating light, add water conservancy project and make indicator lamp, high water level indicator lamp, low water level indicator lamp, digital display temperature controller also is housed, change-over switch, power switch is housed, the trough of electric wire, relay and binding post in casing, it is characterized in that time controller also is housed on cabinet panel, the TS signal processing circuit is housed in casing.

The TS signal processing circuit is made up of following three circuit: diode bridge rectifier circuit, four groups of triodes amplify control relay circuit and diode is close to the road holding circuit.Diode bridge rectifier circuit is made up of transformer, 4 diodes and capacitor, and its effect is the stable direct current that the 220V50HZ alternating current is converted to 24V.Four groups of triodes amplify control relay circuit, and its every group of circuit includes resistance, triode, relay and indicator lamp and form.External signal after triode amplifies, is made relay closes or disconnection, so that relay control main circuit.It is that protective relay has burning voltage and operate as normal that diode is close to the road holding circuit.The time controller of being adorned on the cabinet panel can be selected the 168B type for use.

When being applied to the fuel oil heating boiler, at first on 168 control time in program design circuit KS, will require the shutdown and the working time of boiler to configure, it is synchronous to adjust clock and standard time, goes to require start during the moment relay K when hour hands ₇Must be electric, connect digital display temperature controller XMTD.This moment is if boiler water temperature is lower than institute when requiring temperature, the normally opened contact TK of digital display temperature controller ₂Connect relay K ₁Connect working boiler combustor M ₁Burning is when boiler water temperature rises to when temperature required the normally-closed contact TK of digital display temperature controller ₁Disconnect relay K ₁Dead electricity disconnects, working boiler combustor M ₁Burn-out, boiler quits work.When clock is gone to the moment that requires shutdown, K ₇Dead electricity disconnects, digital display temperature controller XMTD dead electricity, K ₁Dead electricity disconnects, working boiler combustor M ₁Burn-out, boiler is in off-mode.

When being applied to the fuel oil boiler, it is good at first will to require boiler to shut down with the time set of work on 168 control time in program design circuit KS, and adjust clock and the standard time synchronous.When clock is gone to start during the moment, K ₇Must be electric, digital display temperature controller XMTD connects, TK ₂Connect K ₁Get electric connection, working boiler combustor M ₁Burning work, water temperature rise to when temperature required, TK ₁Disconnect K ₁Dead electricity disconnects, working boiler combustor M ₁Burn-out, drinking water boiler are in insulation class.In above-mentioned start simultaneously, the TS signal processing circuit gets electric, if boiler is when being in exsiccosis, and relay K ₅Get electric connection, K ₁Outage, working boiler combustor M ₁Do not work K ₂Must be electric, connect, add wetting system M ₂Work adds water.When water level rises to high water level, relay K ₄Action, K ₂Dead electricity adds wetting system M ₂Stop to add water.When the clock of 168 control time in program design circuit is gone to shutdown during the moment, relay K ₇Dead electricity, digital display temperature controller XMTD dead electricity, TK ₂Disconnect, the TS signal processing circuit is dead electricity simultaneously, K ₁Dead electricity disconnects, working boiler combustor M ₁Do not work, boiler is in shut-down-phase.

When being used for the fuel oil boiler for low-pressure steam steamed rice,

With change-over switch K ₆When converting the state of steamed rice shown in the circuit to, change-over switch K ₆Engage relay K ₃Normally opened contact K ₃, steam pressure is lower than down in limited time in boiler, relay K ₃Connect K ₁Get electric connection, working boiler combustor M ₁Steam pressure rises in the work, boiler, prescribes a time limit when reaching on the steam pressure, and relay K is connected, K ₁Dead electricity disconnects, working boiler combustor M ₁Quit work, when clock is gone to shutdown during the moment, working boiler combustor M ₁Quit work, shut down.

The utility model advantage is with itself and the supporting use of oil burning boiler; do not need fireman's direct control; can be as required; the start of pre-set boiler and downtime; control the start and the shutdown of oil burning boiler by the oil burning boiler time controller; the automaticity height, labor savings is highly suitable for the fuel oil heating boiler of units such as office, school, mine, factory and the application on the fuel oil drinking water boiler.

Embodiment of accompanying drawings:
