Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
The utility model is described in further detail with reference to the accompanying drawings and examples.
The utility model provides a kind of explosion relief door for flour mill, comprising: handle 2, color steel casement door plate 4, bursting diaphragm 11
With thermal insulation layer 12；
Wherein, the side of the color steel casement door plate 4 is provided with LED display 6, and the LED display 6 and color steel casement door plate 4 are solid
It is fixed to connect, it is equipped with toughened glass window 5 below the LED display 6, is equipped with 9 He of dust monitor below the toughened glass window 5
Loudspeaker 10, the dust monitor 9 and loudspeaker 10 are fixedly connected with color steel casement door plate 4 respectively, and the dust monitor 9 is distinguished
It is electrically connected with LED display 6 and loudspeaker 10.
One end of color steel casement door plate 4 is arranged in the handle 2, and the other end of color steel casement door plate 4 is equipped with screw 7 and hinge 8, hinge
8 are fixedly connected by screw 7 with color steel casement door plate 4, and microphone 3 is provided with above the handle 2, is provided with below the handle 2
Microphone switch 1, the handle 2, microphone 3, microphone switch 1 are fixedly connected with color steel casement door plate 4 respectively, the microphone 3
It is electrically connected with microphone switch 1.
The side of the bursting diaphragm 11 is provided with thermal insulation layer 12, and the other side of the bursting diaphragm 11 is fixedly attached to the coloured silk
Steel casement door plate 4.Further, the shape of the toughened glass window 5 can be rectangle.Further, the quantity of the hinge 8 can
Think two groups.
Referring to Fig.1, microphone switch 1 is used to control the opening and closing of microphone 3, for example, security official pins microphone
Switch 1 is spoken against microphone 3, then sound can be amplified by loudspeaker 10, and the staff in workshop is prompted to notice that dust is super
Mark, staff can give situation report-back to factory chief leading cadre by microphone 3 by sound transmission to total activation room.Work
Explosion relief door can be opened using handle 2 by making personnel.This explosion relief door can be pushed the door open or be pulled open with bidirectional opening, staff
Door can also be opened only to side, and door-opening mode is without being limited thereto.
LED display 6 can show air-borne dust content in workshop, and LED display 6 can be 40 × 40 equal lattice displays
Device, but not limited to this.The shape of toughened glass window can be it is rectangular or round, but not limited to this.Dust monitor 9 and loudspeaker
10 electrical connections, once dust monitor 9 detects dust to reach explosion limit, loudspeaker 10 then issues alarm signal, warning
Staff withdraws scene.Hinge 8 is fixedly connected by screw 7 with color steel casement door plate 4, is produced with ensuring that explosion relief door can release explosion
Raw heat.
In addition, the side for being provided with dust monitor 9 of color steel casement door plate 4 should could rise in this way towards inside dust workshop
To the effect of detection dust.The explosion relief door should use explosion-proof lamp and element, and the circuit of the inside is avoided to generate electric spark.
Referring to Fig. 2, thermal insulation layer 12 can effectively completely cut off the heat transfer between extraneous and flour mill workshop, prevent the external world
Temperature is excessively high.Since temperature raises, explosion limit range increases, i.e., lower limit reduces, the upper limit increases, therefore thermal insulation layer 12 can also be prevented
The generation only exploded.Vent panel 11 has good explosion-proof, damages explosion relief door easily.Because if occurring quick-fried
Fried, common door is damaged, and the fragment of door also can be to causing damages outside workshop.
Dust monitor 9 can be pm2.5 tester or pm10 detector, but not limited to this.Dust monitor 9 should have
The features such as test speed is fast, and portable direct-reading, high sensitivity, stability is good, easy to operate, noise-less pollution, AC and DC.Powder
Dirt detector 9 can measure bug dust concentration simultaneously and be greater than powder dust particle Particle density, energy storing data, respirable dust
(PM2.5) and directly the instrument of dirt in air concentration is observed.Different workshops have different requirements, and general work place dust is dense
Degree must not exceed 10mg/m3。
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is modified the technical solutions described in the foregoing embodiments, or to some or all of the technical features
It is equivalently replaced, the scope of the technical solutions of the embodiments of the utility model that it does not separate the essence of the corresponding technical solution.
