Abstract
The utility model discloses a too high alarm device of belt motor electric current, including box and the alarm of setting outside the box, install switching power supply, current induction switch on the inner wall of box, current induction switch's input/output end is connected with the power of motor, and when motor current exceeded current induction switch default, current induction switch's control end and alarm, switching power supply formed the return circuit. If the belt is blocked, the motor current is too large to exceed the preset value, the alarm gives out alarm sound or twinkling light, so that the worker can be reminded to timely close the equipment, the material can be timely cleaned, the blocking amount is reduced, and the reliability of the material conveying system is improved.
Description
Technical Field
The utility model belongs to the technical field of aluminium electroloysis purifies feed motor, concretely relates to belt motor electric current overhigh alarm device.
Background
In the production process of aluminum electrolysis enterprises, the belt conveying capacity of the purification feeding system is large, the production task is heavy, and the effective use of the safety early warning device has important significance. The putty takes place occasionally in actual production process, and when taking place the putty, motor current is too high, if the discovery not in time not only causes very big harm to equipment, seriously influences production efficiency simultaneously. Because the belt conveyer belt is longer, it is difficult to find and avoid accidents only by the patrol of post staff.
Disclosure of Invention
To the not enough of above-mentioned prior art existence, the utility model provides a too high alarm device of belt motor electric current.
The utility model discloses a realize through following technical scheme:
the utility model provides a too high alarm device of belt motor electric current, includes the box and sets up the alarm outside the box, installs switching power supply on the inner wall of box, still installs current-sensing switch at the box inner wall, and current-sensing switch's input/output end is connected with the power of motor, and when motor current exceeded current-sensing switch default, current-sensing switch's control end formed the return circuit with alarm, switching power supply.
Preferably, the switching power supply is a 220V to 12V power supply.
Preferably, the alarm device is further provided with a leakage protector, and a power supply of the motor is connected with the input end of the switch power supply through the leakage protector.
Preferably, the alarm is an audible and visual alarm which is composed of an LED, a loudspeaker and a resistor.
And setting the maximum working current as an upper limit alarm value according to the normal feeding of the belt motor.
Adopt the utility model discloses an alarm device can discover the putty the very first time, reminds the staff to notice in time to close equipment, in time clears up the material, reduces the putty volume to promote defeated material system reliability.
Drawings
Fig. 1 is a schematic diagram of the circuit connection of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The utility model provides a too high alarm device of belt motor electric current, includes the box and sets up the alarm outside the box, installs switching power supply, current induction switch on the inner wall of box, in order to save space, convenient maintenance, can set up the chamber door of switch with a side of box, current induction switch also can set up on the inboard of chamber door. The input end and the output end of the current sensing switch are connected with a power supply of the motor, and when the current of the motor exceeds the preset value of the current sensing switch, the control end of the current sensing switch, the alarm and the switching power supply form a loop. The circuit diagram of the utility model is shown in figure 1.
In order to be used safely, a leakage protector is arranged below the box body, and a power supply of the motor is connected with the input end of the switching power supply through the leakage protector.
In order to facilitate monitoring, the alarm can be arranged in the main control room.
The switching power supply supplies power to the alarm, and the switching power supply is used for converting 220V into 12V. The alarm is composed of 40 LED, speaker and 100 omega resistor.
During the use, take place the putty like the belt, motor current surpasss and predetermines the alarm value, and the sound or the light of scintillation that the alarm sent out the police dispatch newspaper can remind the staff to pay attention to in time close equipment, in time clear up the material, reduce the putty volume to promote defeated material system reliability.
