Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description:

The utility model portable pipe be evacuated dedusting air-flow monitoring alarm as shown in Figure 1, include power supply unit 1, Alarm unit 2, detection unit 3, housing unit 4 and fills unit 5.In the present embodiment, alarm unit 2 is sound-light alarm Device, detection unit 3 are micro differential pressure switch, and fills unit 5 is filling sponge, and carrying unit 4 is suitcase.Filling sponge 5 is placed In Portable suitcase 4, it is identical with power supply unit 1, combined aural and visual alarm 2 and micro differential pressure switch 3 to be provided with 3 size shapes Fixing groove, power supply unit 1, combined aural and visual alarm 2 and micro differential pressure switch 3 are individually positioned in corresponding fixing groove.5 energy of filling sponge It enough prevents from occurring to vibrate in carrying and moving process leading to the problem of collision damages between device.Power supply unit 1, acousto-optic report It is electrically connected between alert device 2 and micro differential pressure switch 3.

By adopting the above technical scheme, it is detected, can be sent out at the first time by pressure of the detection unit 3 to pump-line Now pumping blower stops working, and reminds deashing operator to stop operation in time, avoids the generation of accident.

Micro differential pressure switch is as shown in Fig. 2 to 3, including circuit interface 31, the first air-path interface 32 and the second air-path interface 33, wherein first air-path interface 32 connects the relatively high one side of air pressure in gas circuit, and second air-path interface 33 connects air pressure phase To low one side, in the present embodiment, first air-path interface 32 is left a blank, and is communicated with the atmosphere, second air-path interface 33 connection pump-lines.There are set of circuits connector, including common point 34, opened point 35 and normally closed point 36 inside micro differential pressure switch 3.

When being evacuated blower work, have air-flow flowing in pump-line, at this time the two of micro differential pressure switch 3 air-path interface it Between there are pressure difference, switch is contacted with normally closed point 36 at this time, and common point 34 and normally closed point 36 are connected, circuit disconnection, sound-light alarm Device 2 is without alarm.

When pumping blower stops working, there is no air-flow flowing in pump-line, at this time the two of micro differential pressure switch 3 gas circuit Pressure difference becomes smaller even zero between interface, illustrates that being evacuated blower stops working, switch is contacted with opened point 35 at this time, common point 34 are connected with opened point 35, and circuit conducting, combined aural and visual alarm 2 is alarmed, and deashing operator is reminded to stop deashing.

When specifically used, the power switch 12 on power supply unit 1 is first opened before access conduit, two gas circuits connect at this time Mouthful communicated with atmosphere, without pressure difference, device alarm be it is normal, do not alarm as exception, it is ensured that general in the normal situation of device Second air-path interface 33 of micro differential pressure switch 3 is accessed in pump-line by hose, and suction hose and pipe joint are according to second The bore of air-path interface 33 is by user configuration, if stop alarm, proves that pipeline has air-flow, if alarm, it was demonstrated that pipeline airless； Check whether pumping blower is opened, whether pipeline valve abnormal etc..

The present apparatus is capable of the exhausting situation of real-time detection pipeline, reminds operating personnel in time when exhausting stops, ensure that The safety of operating personnel.Fixing groove is set on filling sponge, power supply unit, alarm unit and micro differential pressure switch are put into accordingly Fixing groove in, can isolate and protect each unit, gap between each unit is filled up, when avoiding colliding or shaking Cause instrument damage.Two ways can be changed by sound and light using combined aural and visual alarm and remind deashing operator, more preferably It reminds deashing operator to pay attention to warning message, found the abnormal situation in time, deashing operator is avoided not notice warning message, There is a situation where accidents.Power supply unit, alarm unit and micro differential pressure switch are contained using Portable suitcase convenient for deashing operation Person carries, and can carry out examinations in any operating position, improve safety.

Above embodiment is intended to illustrate the utility model and can realize or use for professional and technical personnel in the field, right Above embodiment, which is modified, will be readily apparent to those skilled in the art, therefore the utility model includes But it is not limited to above embodiment, it is any to meet the claims or specification description, meet and principles disclosed herein With novelty, the method for inventive features, technique, product, each fall within the protection scope of the utility model.
