Abstract
The utility model relates to a dust catcher ash bucket high material level detecting device, which comprises a pressure sampling pipe, a flexible pipe and an intelligent pressure digital display instrument, wherein the pressure sampling pipe comprises a straight tube and a bent head, and is mounted on the middle upper portion of an ash bucket, the intelligent pressure digital display instrument is connected with the pressure sampling pipe through the flexible pipe, and is mounted on the lower portion of the ash bucket. Negative pressure of the ash bucket is transferred to the intelligent pressure digital display instrument by the pressure sampling pipe, thereby reaching the detection function. Since the dust catcher ash bucket high material level detecting device only comprises the pressure sampling pipe, the flexible pipe and the intelligent pressure digital display instrument, the dust catcher ash bucket high material level detecting device has simple structure, low cost, accurate and reliable material level detection and convenient maintenance.
Description
One, technical field
The utility model relates to a kind of dust collector ash hopper high charge level pick-up unit.
Two, background technology
At present, the ash of the fly-ash separator on market position monitoring alarm radio frequency admittance level-sensing device commonly used and motor resistance move the formula level-sensing device.More than two kinds of level-sensing devices have following shortcoming: 1. the radio frequency admittance level-sensing device belongs to the contact level-sensing device, and ash is in case to stick caking serious just malfunctioning easily, and zero point promptly occurring drift needs to recalibrate; 2. resistance moves the formula level-sensing device under the working condition of the inner abominable dust of ash bucket, and mechanical moving element damages easily, and serviceable life is shorter; 3. the high charge level meter is arranged in the middle and upper part of ash bucket, and most of power plant does not design ash bucket material level inspection platform, safeguards commissioning staff's trouble hunting difficulty; 4. ash bucket is in case grey fault is blocked up in appearance, and level-sensing device probe position ubiquity bends and damages metaboly, causes extracting replacing.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, with low cost, material level and detects accurately and reliably and dust collector ash hopper high charge level pick-up unit easy to maintenance.
For achieving the above object, solution of the present utility model is:
This device is made up of pressure samples pipe, flexible pipe, intelligent pressure digital display instrument, and described pressure samples pipe is made up of straight tube and elbow, is installed in the middle and upper part of ash bucket, and described intelligent pressure digital display instrument is connected with the pressure samples pipe by flexible pipe, is installed in the ash bucket below.
During system works, by the pressure samples pipe ash bucket negative pressure is sent to intelligent pressure digital display instrument, when dust collector ash hopper blocks up ash, intelligent negtive micropressure switch detects normal negative pressure, export normal material level signal, when ash bucket blocks up ash to high charge level, the pressure samples tube head is stopped up negative pressure by dust stratification and disappears, at this moment intelligent digital display pressure gauge detected pressures is zero, by the predefined pressure divergence alarming value of function key, thereby export the high charge level alerting signal to low voltage control system, thereby reach the material level warning function.Because the utility model only is made up of pressure samples pipe, flexible pipe, intelligent pressure digital display instrument, can reach simple in structure, with low cost, material level detection accurately and reliably with purpose easy to maintenance.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Sign expression respectively among the figure:
1. lead 2. intelligent pressure digital display instruments 3. flexible pipes 4. pressure samples pipes
5. elbow 6. ash buckets 7. dusts
Five, embodiment
As can be seen from Figure 1, the utility model pressure samples pipe 4, flexible pipe 3, intelligent pressure digital display instrument 2 are formed, and pressure samples pipe 4 is made up of straight tube and elbow 5, is installed in the middle and upper part of ash bucket 6, intelligent pressure digital display instrument 2 is connected with pressure samples pipe 4 by flexible pipe 3, is installed in ash bucket 6 belows.
Connect lead 1 intelligent pressure digital display material instrument 2 when in running order, by pressure samples pipe 4, connect flexible pipe 3 ash bucket 6 negative pressure are sent to intelligent pressure digital display instrument 2, when dust collector ash hopper 6 blocks up dust 7, negtive micropressure switch detects normal negative pressure in the intelligent pressure digital display instrument 2, export normal material level signal, when the dust 7 of ash bucket 6 during to high charge level, pressure samples pipe 4 elbows 5 are stopped up negative pressure by dust 7 and disappear, at this moment to detect ash bucket 6 pressure be zero to the intelligent pressure digital display instrument, by the predefined pressure divergence alarming value of function key, lead 1 is exported the high charge level alerting signal to low voltage control system, thereby reaches the material level warning function.Intelligent pressure digital display instrument 2 is installed in electric precipitation zero rice position, and the operation maintenance personnel can observe accurate and visually, judge whether ash bucket 6 blocks up dust 7.
