Abstract
The utility model relates to an aerator protection device, belonging to the technical field of pharmacy auxiliary equipment. The aerator protection device comprises a PLC (programmable logic controller), an wind pressure switch and a contactor, wherein the wind pressure switch is arranged on an aerator outlet pipeline; the contactor is connected with a power supply and an aerator; and the PLC controls the contactor to realize start/stop of the aerator according to a signal sent by the wind pressure switch. According to the aerator protection device provided by the utility model, the operation of the aerator is controlled by a PLC controller; the signal is transferred to the contactor through the PLC, and the power supply is connected to enable the aerator to run; when the wind pressure switch mounted on an aerator outlet operation pipeline cannot detect an airflow passing signal after the aerator is started or an airflow signal disappears suddenly during normal operation, the wind pressure switch transfers a shutdown alarm signal to the PLC, the PLC transfers a shutdown signal to the contactor, and the power supply is cut so as to realize the beneficial effect of protecting the aerator.
Description
Technical field
This utility model belongs to pharmacy auxiliary facilities technical field, is specifically related to a kind of protector of Capsules aerator that production process is used.
Background technology
Hollow capsule production line is that three-shift system is worked continuously, aerator is also continuous operation, once the faults such as the stuck or circuit phase shortage of machinery occur in aerator, tend to cause the aerator load excessive and burn, if can not find in time, capsule production line will produce a large amount of waste products, and maintain and replace need to be wasted a large amount of working times simultaneously.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple aerator protector efficiently.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is; a kind of aerator protector; comprise PLC, blast switch and catalyst; described blast switch is arranged on the aerator outlet conduit; described catalyst connects power supply and aerator, and the signal sent according to blast switch, realized the start and stop of aerator by PLC controller control contactor.
This utility model aerator protector; by the PLC controller, to aerator, operation is operated; signal passes to catalyst by PLC and switches on power and make aerator operation; be arranged on the blast switch on the aerator export pipeline; can't detect signal that air-flow passes through or normal in service while losing airflow signal suddenly after start; blast switch sends the stopping alarm signal to PLC; PLC sends stopping signal to catalyst; cut off the electricity supply, thereby reach the beneficial effect to the aerator protection.
As this utility model, further improve, the aerator protector comprises control panel, and PLC sends stopping signal to catalyst, and simultaneously, PLC sends alarm signal to control panel, and control panel sends sound and light alarm and reminds operator to carry out associative operation.
The accompanying drawing explanation
Accompanying drawing is that this utility model aerator protector is controlled schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in the figure; this utility model aerator protector; it comprises blast switch 1, PLC controller 2 and catalyst 3; signal passes to catalyst 3 by PLC controller 2 and switches on power and make aerator operation; be arranged on the blast switch 1 on aerator outlet operation pipeline; after starting, aerator can't detect signal that air-flow passes through or normal in service while losing airflow signal suddenly; blast switch 1 sends the stopping alarm signal to PLC controller 2; PLC controller 2 sends stopping signal to catalyst 3; cut off the electricity supply, aerator quits work.
As improvement; this utility model aerator protector comprises control panel 4; the PLC controller sends stopping signal to catalyst 3; simultaneously; PLC controller 2 sends alarm signal to control panel 4; control panel 4 sends sound and light alarm and reminds operator to carry out associative operation, and as preferably, control panel 4 adopts the touch controls screen.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this utility model the scope of the claims; it should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (3)
