Abstract
The utility model provides a time-delay stopping circuit for a dedusting device. The time-delay stopping circuit comprises a stopping switch and a control module, wherein the stopping switch is connected with the control module and the control module is used for controlling operation of the dedusting device. The circuit also comprises an intermediate relay, a first time relay and a second time relay, wherein the intermediate relay comprises a first normal open contact, the first time relay comprises a first normally closed contact, the second time relay comprises a second normal open contact and the second normal open contact of the second time relay is connected with the control module. A power-supply input terminal is successively connected with the first normally closed contact of the first time relay and the second normal open contact of the second time relay in parallel. The first normally closed contact of the first time relay is connected with the stopping switch in series. The second normal open contact of the second time relay is connected with the stopping switch in parallel. A power-supply output terminal is connected with the intermediate relay, the first time relay and the second time relay in parallel. After the stopping switch is pressed down, the dedusting device continually operates in setting time and then automatically powers off.
Description
Technical field
The application relates to a kind of circuit control device, especially relates to a kind of time-delay halt circuit that is used for cleaner.
Background technology
The lead-acid accumulator industry because of producing a large amount of lead fume and dust in its production run, therefore, need to use the environmental protection cleaner, and the frequent damage of the filter cylinder in the environmental protection cleaner has caused equipment can not well play the effect of dedusting.Research by analysis, the normal reason of damaging of filter cylinder is: after the same day, production stopped, press the shutdown switch of cleaner, cleaner quits work, but the still residual a large amount of dust in the filter cylinder surface of cleaner inside, next time, the dust of accumulation was easy to cause the filter cylinder of equipment to damage when opening cleaner.
Summary of the invention
The utility model provides a kind of time-delay halt circuit that is used for cleaner, after pressing shutdown switch, in the time of setting, continues the operation cleaner; After the time of setting, cleaner is out of service.
For achieving the above object, the utility model provides a kind of time-delay halt circuit that is used for cleaner, comprising: shutdown switch and control module, and shutdown switch is connected control module, the operation of control module control cleaner; Also comprise:
Auxiliary reclay, auxiliary reclay comprise first normally opened contact;
Very first time relay, very first time relay comprises first normally closed contact;
With second time relay, second time relay comprises second normally opened contact;
The second normally opened contact link control module of second time relay;
First normally closed contact of power input very first time relay in parallel successively and second normally opened contact of second time relay;
First normally closed contact of very first time relay and shutdown switch series connection, second normally opened contact of second time relay and shutdown switch parallel connection;
Power output end auxiliary reclay in parallel, very first time relay and second time relay.
The application's beneficial effect is: use this dedusting time-delay stop device, press shutdown switch after, PLC is connected in the contact time-delay of second time relay, stop signal is sent in control PLC time-delay; The contact time-delay of the very first time time relay disconnects, and cuts off the electricity supply.Thereby make press shutdown switch after, fly-ash separator continues operation, and behind end of run, cuts off the electricity supply.
Description of drawings
Fig. 1 is used for the time-delay halt circuit of cleaner for the utility model is a kind of circuit connects intention;
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
The cleaner of this device is a pulse dust collector, control module is programmable logic controller (PLC) PLC, be used for cleaner time-delay halt circuit, comprise: shutdown switch S and PLC, shutdown switch S connects control module, wherein, the first normally closed contact K2 of power input L described very first time relay K T1 in parallel successively and the second normally opened contact K3 of second time relay KT2, the first normally closed contact K2 of very first time relay K T1 and shutdown switch S series connection, the second normally opened contact K3 of second time relay KT2 and described shutdown switch S parallel connection; Power supply output N described auxiliary reclay KA, described very first time relay K T1 in parallel and described second time relay KT2.
The staff presses shutdown switch S after work, auxiliary reclay KA, very first time relay K T1, second time relay KT2 simultaneously electric, the first normally opened contact K1 of auxiliary reclay KA connects
The delay time that very first time relay K T1 sets omits delay time long and second time relay KT2, if the delay time that very first time relay is set is 1 hour 3 seconds, second time relay is set at 1 hour.After the delay time of setting arrived in 1 hour, the second normally opened contact K3 closure of second time relay KT2 was connected PLC, and PLC sends stop signal, stops the operation of cleaner.In a hour of time-delay, pulse dust collector continues operation, the dust of piling up on the pulse continuation winding-up filter cylinder.
After the 1 hour 3 seconds time that very first time relay is set arrived, the first normally closed contact K2 of very first time relay K T1 disconnected, and cuts off the electricity supply.
Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace.
