Abstract
The utility model relates to a blockage detection device of an aeration system. The blockage detection device comprises a housing, a pipe joint I and a pipe joint II; the periphery of the housing is sealed, a cavity is disposed in the housing, and the pipe joint I and the pipe joint II are installed on the left side and the right side of the housing; and an outer end of the pipe joint I and an outer end of the pipe joint II are respectively provided with an outer screw thread I and an outer screw thread II, a through hole I and a through hole II are respectively disposed in the pipe joint I and the pipe joint II, the through hole I and the through hole II are communicated with the cavity respectively. When a gas pipe is unobstructed, gas pressure pushes a moving contact communicated iron sheet up, and the iron sheet is straightened upward by means of a gas push force, so that a moving contact is attached to a static contact, a loop forms a pathway, and a pathway signal is generated between a lead wire I and a lead wire II. On the contrary, when the gas pipe of an aerator is obstructed, the pipeline has an enclosed environment, and gas pressures are balanced in the pipeline; and, at this point, the moving contact presses a relative support rod of the moving iron sheet to bend downward under the action of the own gravity, the moving contact goes away from the static contact so that the lead wire I and the lead wire II are disconnected, and a disconnection signal is provided when detection.
Description
Technical field
The utility model relates to pick-up unit technical field, is specifically related to a kind of aerating system blockage detector.
Background technology
In sewage treatment plant, the quality of aeration tank operation directly affects the normal operation of whole sewage treatment plant, it fully mixes sewage by blast aeration in pond with microorganism, the active sludge being suspended in sewage contacts with organism, make the organism dissolving be entered cell interior by bacterial adsorption and absorption, under the effect of endocellular enzyme, carry out oxygenolysis.Aeration tank adopts aerator for aerobic microbiological provides oxygen, guarantees carrying out smoothly of aerobic section.But aerator is due to a variety of causes, and its internal duct is often stopped up, and affects the use of aerator, thereby affect the normal operation of whole flow process.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, provide a kind of can Real-Time Monitoring aerating system in the aerating system blockage detector that whether stops up of air pipe inside.
The utility model overcomes the technical scheme that its technical matters adopts:
This aerating system blockage detector, comprise that surrounding sealed inside is provided with the housing of cavity, be installed on pipe adapter I and the pipe adapter II of the housing left and right sides, described pipe adapter I and pipe adapter II outer end are respectively arranged with external thread I and its inside of external thread II is respectively arranged with through hole I and through hole II, described through hole I and through hole II are communicated with cavity respectively, in described cavity, top is fixed with static contact, its bottom is provided with support bar, the upper end of described support bar is provided with iron plate, the top of described iron plate is fixed with moving contact, the lead-in wire I and the lead-in wire II that are arranged at outside housing are connected to static contact and moving contact, press iron plate to the direction bending away from static contact at Action of Gravity Field lower moving contact.
In order better to realize moving contact to away from the bending of static contact direction, the relative static contact of above-mentioned support bar is to tilting to be fixed in cavity away from direction.
The beneficial effects of the utility model are: in the time that gas piping is unobstructed, moving contact is communicated with iron plate jack-up by gaseous tension, by the thrust of gas, iron plate is upwards stretching, thereby moving contact and static contact laminating, loop forms path, so produce a path signal between lead-in wire I and lead-in wire II.In contrast, when the tracheae of aerator stops up, pipeline is a closed environment, pipe interior gas pressure balancing, now, moving contact presses the relative support bar of iron plate and is bent downwardly under self gravitation effect, and away from static contact, thereby between lead-in wire I and lead-in wire II, disconnecting, when detection, is exactly a cut-off signal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. housing 2. pipe adapter I 3. pipe adapter II 4. external thread I 5. external thread II 6. through hole I 7. through hole II 8. cavity 9. support bar 10. iron plate 11. moving contacts 12. I 13. II 14. static contacts that go between that go between.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described further.
This aerating system blockage detector, comprise that surrounding sealed inside is provided with the housing 1 of cavity 8, be installed on pipe adapter I 2 and the pipe adapter II 3 of housing 1 left and right sides, described pipe adapter I 2 and pipe adapter II 3 outer ends are respectively arranged with external thread I 4 and external thread II 5 its inside are respectively arranged with through hole I 6 and through hole II 7, described through hole I 6 and through hole II 7 are communicated with cavity 8 respectively, the interior top of described cavity 8 is fixed with static contact 14, its bottom is provided with support bar 9, the upper end of described support bar 9 is provided with iron plate 10, the top of described iron plate 10 is fixed with moving contact 11, the lead-in wire I 12 and the lead-in wire II 13 that are arranged at outside housing 1 are connected to static contact 14 and moving contact 11, press iron plate 10 to the direction bending away from static contact 14 at Action of Gravity Field lower moving contact 11.This aerating system blockage detector is installed on tracheae pipeline by pipe adapter I 2 and the pipe adapter II 3 at two ends, utilizes external thread I 4 and external thread II 5 to screw in the threaded hole that is fixed on two lateral lines, form closely and connect.In the time that gas piping is unobstructed, the relative external atmospheric pressure of pipeline pressure has pressure differential, gas in tracheae pipeline moves freely, be accompanied by the movement of gas, moving contact 11 is communicated with iron plate 10 jack-up by gaseous tension, by the thrust of gas, iron plate 10 is upwards stretching, thereby moving contact 11 is fitted with static contact 5, loop forms path, thus produce a path signal from lead-in wire I 12 with going between between II 13, in the time that pulpit or control system detect this signal, just represent that pipeline is unobstructed, aerator is normally worked.In contrast, when the tracheae of aerator stops up, pipeline is a closed environment, pipe interior gas pressure balancing, now, moving contact 11 presses the relative support bar 9 of iron plate 10 and is bent downwardly under self gravitation effect, and away from static contact 14, thereby between lead-in wire I 12 and lead-in wire II 13, disconnect, when detection, be exactly a cut-off signal, pulpit or distant place control system can utilize this signal to carry out further work, produce and report to the police or process aerator.
The relative static contact 14 of support bar 9 is to tilting to be fixed in cavity 8 away from direction.Therefore when moving contact 11 contacts with static contact 14, its relative level face is that its center of gravity of heeling condition moves laterally, and in the time that pipeline occurs to stop up, moving contact 11 can press rapidly iron plate 10 bendings under Action of Gravity Field, has improved the reliability using.
