Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] refer to figure 1 , the embodiment of the present invention provides a bag filter air source pressure automatic monitoring device, the device includes an electronic pressure sensor 100 fixedly installed on the air intake pipe near the bag filter, and the pressure sensor 100 is sequentially electrically connected to a digital display pressure gauge 110 and a digital display time relay 120 . When the pressure sensor 100 detects the high and low air press...

The invention discloses an automatic air source pressure monitoring device and an automatic air source pressure monitoring method for a bag type dust collector, and relates to the technical field of dust collectors. The device comprises an electronic pressure sensor, a digital display pressure gauge and a digital display time relay, wherein the pressure sensor converts low and high values of monitored air source pressure into low and high voltage signals; a solid state relay in the digital display pressure gauge outputs corresponding on and off switching value signals, and connects the on and off switching value signals to a reset point in the digital display time relay. When the air source pressure is low, the reset point of the digital display time relay is disconnected, and the digital display time relay starts to count time; furthermore, when a set time length is greater than an interval between every two spray vibrations of an electromagnetic valve on an air pocket of the dust collector, the device automatically sends a group of feedback signals to a user for use. According to the device and the method, all the components are long in service life, and when the air source pressure of the running dust collector is suddenly in a continuous low-value period, an accurate judgment can be made and the group of feedback signals can be automatically sent to the user for use.
Description
technical field [0001] The invention relates to the technical field of bag type dust collectors, in particular to an automatic monitoring device and method for air source pressure of bag type dust collectors. Background technique [0002] One of the prerequisites for the benign operation of the bag filter is that there is an important requirement for constant and stable pressure on the inlet pressure of the bag filter air bag. When the air intake pressure of the air bag of the dust collector is suddenly at a low value during operation, the ash powder adsorbed on the surface of the filter bag inside the dust collector will not be completely or cannot be shaken off by the pulse vibration, and the ash powder will continue to accumulate On the surface of the filter bag, the dust extraction fan is still drawing air at this time, which not only increases the running resistance of the dust collector, but also may cause the bag to be damaged by the dust extraction fan, which will ea...
