Description
Technical field
The utility model belongs to a kind of measuring instrument, especially a kind of bag-type dust dustiness on-line monitoring system.
Background technology
Bag-type dust is one of dust collection method of industrial dust, is commonly used in pulverized-coal fired boiler flue gas ash removal and blast furnace famine, purified gas dedusting, and application is also arranged in cement industry at present.Because cloth bag uses for a long time, damaged easily, thus make the dust discharging that just exceeds standard, follow-up facility is stopped up and wearing and tearing or break, affects safety production and contaminated air environment, so press for and utilize monitoring equipment that dust concentration is effectively monitored.
Traditional dust concentration monitoring method has two kinds, and a kind of is manually measured medium to be discharged through probe tube, watches it to contain Dust Capacity, and this method can only obtain the big probable value of dust concentration; Another kind method is to utilize weight method, the i.e. dust that will monitor, by the sampling of bleeding of certain hour, certain flow, on the floating dust film, with the dust oven dry, claim its weight with dust-filtering then, just know dust concentration as calculated, this method not only intermittently but also cumbersome, can't be known continuous operation conditions, was difficult to adapt to produce needs.The bag-type dust dustiness on-line monitoring system that utilizes the electric charge induction technology at present is more advanced concentration monitor device, in the existing concentration monitor device, sensor of dust concentration directly is connected with terminal box, because tested pressure along it is bigger in the measuring channel, therefore moisture and the gas in the dust is easy to infiltrate in the sensor terminal box, electronic circuit component in the butted line box damages, and has not only influenced certainty of measurement, and has shortened the service life of sensor greatly.
The utility model content
The purpose of this utility model is to overcome the defective of existing bag-type dust dustiness on-line monitoring system poor air-tightness, has proposed a kind of bag-type dust dustiness on-line monitoring system that has the part that is tightly connected.
The utility model is to adopt following technical scheme to realize: a kind of bag-type dust dustiness on-line monitoring system that has the part that is tightly connected, comprise sensor of dust concentration, sensor comprises probe, closely be coated with anticorrosive casing pipe on the outer circumference surface of probe, the upper outside of probe is connected with pressure jacket, be connected by interference fit between pressure jacket and the probe, the outside of pressure jacket is provided with fastening connection piece, be connected by interference fit between fastening connection piece and the pressure jacket, wherein, the fixedly connected part that is tightly connected in the top of fastening connection piece, the be tightly connected lower end of part is connected with fastening connection piece, fixedlying connected with junction box body in the upper end, is tightly connected to be interference fit between part and the pressure jacket.
In the utility model, the middle part of termination, described probe top is provided with an internal thread hole, and by screw crimping signal transmission wire, the other end of lead is connected with signal picker, and signal picker is arranged in the terminal box.
The outer wall attached cable joint of described junction box body, two core cables are fixed in the cable connector.
The beneficial effects of the utility model are: by the top at probe the part that is tightly connected is set, strengthened the air-tightness of sensor of dust concentration, make the signal picker that is arranged in the terminal box or other electronic components can operate as normal, guarantee certainty of measurement, prolonged the service life of on-line monitoring system.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, this monitoring system comprises sensor of dust concentration, and sensor comprises an elongated circular metal probe 8, and it is positioned at the center of sensor.Closely be coated with anticorrosive casing pipe 7 on the outer circumference surface of probe 8, because tested flue gas has stronger corrosivity, anticorrosive casing pipe 7 can prevent that probe 8 is corroded, and improves the service life of probe 8.The upper outside of probe 8 is connected with pressure jacket 5, and it is used to intercept measured gas atmosphere, and the pressure that produces in buffering installation or the production process prevents to cause probe to be out of shape owing to pressure is excessive or break.Be connected by interference fit between pressure jacket 5 and the probe 8.The outside of pressure jacket 5 is provided with fastening connection piece 4, is connected by interference fit between fastening connection piece 4 and the pressure jacket 5.The top of fastening connection piece 4 is fixedly connected with the part 3 that is tightly connected, be tightly connected an end and the fastening connection piece 4 of part 3 by being threaded, the other end and junction box body 2 are connected by engage thread, be tightly connected and be interference fit between part 3 and the pressure jacket 5, the part 3 that is tightly connected can prevent effectively that moisture and the gas in the tested pipeline dust from entering in the terminal box, makes the signal picker 10 in the terminal box can operate as normal.The bottom of fastening connection piece 4 is provided with welding base 6, and fastening connection piece 4 is connected by engage thread with welding between the base 6.Welding base 6 is welded on the measuring channel, thereby probe 8 is fixed in the measuring channel.
One end of probe 8 is a measuring junction, vertically inserts in the measured medium, measures coal powder density, the other end is terminals, the middle part of termination, probe 8 top is provided with an internal thread hole, and by screw crimping signal transmission wire 9, the other end of lead 9 is connected with signal picker 10.One end of outer wall attached cable joint 1, two core cable of junction box body 2 is fixed in the cable connector 1, and the other end is connected with the concentration signal transmitter.
When the utility model uses, at first will weld base 6 and be welded on the measuring channel, probe 8 is stretched in the measuring channel, the coal powder density in the pipeline is surveyed, probe 8 is delivered to signal picker 10 with the signal of telecommunication of sensing by signal transmission wire 9.The signal of telecommunication that signal picker 10 is collected is delivered to the concentration signal transmitter by two core cables, the signal of telecommunication is amplified processing after, be converted to data signal or analog signal more as required, thereby can obtain dust concentration value accurately.
In the utility model, also described concentration signal transmitter can be set directly in the terminal box, promptly concentration signal transmitter and sensor of dust concentration are integral structure.This moment, one end of two core cables was fixed in the cable connector, and the other end is connected with switch board or other devices.
Other are with embodiment 1.
