Abstract
The utility model discloses an ice blockage alarming device for a water-cooling refrigerated air dryer. A first pressure sensor is arranged at an inlet of the refrigerated air dryer. A second pressure sensor is arranged at an outlet of the refrigerated air dryer. The first and second pressure sensors are connected with a controller which is connected with an alarm. The refrigerated air dryer is also provided with a shutdown relay driving circuit connected with the controller. The ice blockage alarming device is simple in structure and functionally practical, and an alarm can be automatically given in case of ice blockage of the water-cooling refrigerated air dryer to further prevent dangers.
Description
Technical field
The utility model relates to the stifled warning device of a kind of water-cooled cooling driers ice.
Background technology
Suddenly descend the time in the weather temperature at present, because the cooling water system of water-cooled cooling driers is outer circulation, the temperature of cooling water is lower, and the cooling driers evaporator temperature is reduced, and causes ice stifled when serious; Or improper when the adjustment of water-cooled cooling driers cooling water water inlet expansion valve, be prone to cause ice stifled; Or the air compressor machine discharge time is long, causes load too small, and cooling driers also is prone to cause ice stifled.When cooling driers ice was stifled, the compressed air that air compressor machine produces can not in time be discharged, and causes pressure at expulsion too high, and equipment is caused damage; Compressed air can not in time be supplied production, also can cause great quality accident.
The utility model content
The utility model purpose is to provide a kind of water-cooled cooling driers ice stifled warning device, can realize reporting to the police automatically when water-cooled cooling driers ice is stifled, prevents the further generation that endangers.
To achieve these goals; The utility model adopts following technical scheme: the stifled warning device of a kind of water-cooled cooling driers ice; Import at cooling driers is provided with first pressure sensor; Outlet at cooling driers is provided with second pressure sensor, and first pressure sensor all is connected with controller with second pressure sensor, and controller is connected with alarm.
Cooling driers also is provided with the shutdown relay drive circuit that is connected with controller.
The utility model is simple in structure, function is practical, can realize reporting to the police automatically when water-cooled cooling driers ice is stifled, prevents the further generation that endangers.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: as shown in Figure 1; The stifled warning device of a kind of water-cooled cooling driers ice; Import at cooling driers 1 is provided with first pressure sensor 4; Be provided with second pressure sensor, 5, the first pressure sensors 4 in the outlet of cooling driers 1 and all be connected with controller 2 with second pressure sensor 5, controller 2 is connected with alarm 6.Cooling driers 1 also is provided with the shutdown relay drive circuit 3 that is connected with controller 2.
Cooling driers is when operation, and first pressure sensor and second pressure sensor send to controller with the signal that collects, and controller carries out analyzing and processing, and preset pressure reduction is divided into first pressure reduction, second pressure reduction and the 3rd pressure difference, carries out three times respectively and reports to the police.When pressure reduction during more than or equal to first setting value, send alarm signal for the first time to alarm, remind operating personnel to shut down maintenance; If do not handle, continue start, when pressure reduction during more than or equal to second setting value; Remind once more,, report to the police once more when pressure reduction during more than or equal to the 3rd setting value.Controller sends instruction, makes the shutdown relay closes, system's emergency shutdown.The utility model can in time be reported to the police to cooling driers ice is stifled, and the phenomenon of harm reduction equipment takes place, and ensures the safety of producing.
