Abstract
The utility model relates to a powder leakage detector of a pneumatic conveying system, which is characterized in that the powder leakage detector is arranged in an aspirating chamber end cover of a cyclone separator in the pneumatic conveying system, or arranged on an air pumping pipeline commonly used by a plurality of sets of cyclone separator. The powder leakage detector can be correspondingly arranged for each set of cyclone separator respectively, and once leakage occurs, the phenomenon that powder leakage occurs to the cyclone separator can be immediately indicated, and the cyclone separator can immediately stop running. The powder leakage detector can also be arranged for a plurality of sets of cyclone separators commonly (the position is changed, and the powder leakage detector is arranged on a common air pumping pipeline position), and once a certain cyclone separator leaks powder, the phenomenon that powder leakage occurs to the system can be immediately indicated, and the system can immediately stop running.
Description
Technical field
The utility model relates to a kind of leakage powder detecting device of air-transport system.
Background technology
Air-transport system is used for powder or particulate matter are carried out closed conveying.
Air-transport system comprises cyclone, the radical function of cyclone is particulate solid or the powder that contains in the quick as far as possible divided gas flow, to reach gas-solid separating effect, guarantee the in time stable conveying of material in the pipeline and the normal operation of attendant equipment.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, be suitable for observing the dust exhaustor cloth bag whether the leakage powder detecting device of the air-transport system that leaks material is arranged.
In order to solve the problems of the technologies described above, the utility model provides a kind of leakage powder detecting device of air-transport system, be characterized in: this leakage powder detecting device is located in the aspirating chamber end cap of the cyclone in the air-transport system, or is located on the shared air draft pipe of many cover cyclones.
Further, this leakage powder detecting device have record the dust concentration value greater than preset value and certain time after the alarm signal output ends of output alarm signal and the control signal output ends that the control air-transport system is shut down.
Technique scheme of the present utility model has the following advantages compared to existing technology: the principle of work of the leakage powder detecting device of (1) air-transport system of the present utility model: by being installed in the powder detector in the cyclone aspirating chamber end cap, detect the leakage situation of cyclone inside (aspirating chamber) powder.In system's course of normal operation no dust produce or in certain micro-scope as 50mg/m
3In case the inside cloth bag or the filter core of cyclone break, then cause material directly to discharge through blower fan without filtering system, produce material and fly ease, blower fan damage, environmental pollution.Adopting can preliminary setting parameter value such as 100mg/m behind this powder detecting device
3In case device is promptly reported to the police and the control system shutdown after detecting this numerical value and certain time, enlarges to prevent fault.(2) leakage powder detecting device of the present utility model adopts dynamic charge method principle, can not produce electric charge accumulation, the inferred-zero drift is not subjected to technological process to cause the influence of the electric charge that particulate matter itself carries, single-ended installation, need not blowback, integral structure, simple compact, install simple, advanced technology detects timely and feeds back the service condition of system, has significantly improved the serviceability and the transport efficiency of system.(3) leakage powder detecting device of the present utility model can be installed for every cover cyclone carry out list cover correspondence, can show immediately that there is leakage material phenomenon and out of service immediately in this cover cyclone in case produce to leak.Can also be for many cover cyclones carry out shared installation (shift one's position, be installed on shared air draft pipe position), in case when wherein certain cyclone produce leak then immediately display system have that to leak the material phenomenon also out of service immediately.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
