Abstract

Barometric bin level meter, including appendix, the inlet end of appendix connects gas station, the outlet side of appendix tilts down, and the gas outlet setting gas gathering mask that Open Side Down of appendix, electrically operated valve is set in appendix pipe shaft, pressure transmitter is set between electrically operated valve and appendix outlet side in appendix pipe shaft, the Barometric bin level meter is additionally provided with electronic controller, and the electrically operated valve and pressure transmitter pass through conducting wire respectively and connect with electronic controller.It can make to monitor that original part is washed away from material, fouling etc. influences, and improve service life, it is ensured that the authenticity of measurement data, and then accurate judgement level of filler material state.

Description

Barometric bin level meter

Technical field

The utility model relates to level-sensing device more particularly to a kind of Barometric bin level meters.

Background technique

Level-sensing device refers to the instrument that the variation to solid material height in container is detected.The form of level-sensing device has resistance to move Formula level-sensing device, blocking rotary type level-sensing device and ultrasonic type level-sensing device etc..Resistance shifting formula level-sensing device and blocking rotary type level-sensing device are rushed by material Brush, fouling etc. influence, and monitoring original part easily damages, and service life is low, and measurement data distortion can not accurately judge level of filler material State, ultrasonic type level-sensing device are influenced by the changeable accumulation form of material, can not accurately equally measure the shape of level of filler material State.

Summary of the invention

The utility model is in order to solve the above-mentioned technical problem, to provide a kind of Barometric bin level meter, can make to monitor original part Washed away from material, fouling etc. influences, improve service life, it is ensured that the authenticity of measurement data, and then accurate judgement material material Position state.

The technical solution of the utility model is:

Barometric bin level meter, including appendix are characterized in that the inlet end connection gas station of appendix, appendix Outlet side tilt down, motor-driven valve is arranged in appendix pipe shaft in and gas outlet setting the gas gathering mask that Open Side Down of appendix Door, is arranged pressure transmitter between electrically operated valve and appendix outlet side in appendix pipe shaft, the Barometric bin level meter is also Equipped with electronic controller, the electrically operated valve and pressure transmitter pass through conducting wire respectively and connect with electronic controller.

Further preferably, the gas gathering mask is bell mouth shape.

The beneficial effects of the utility model are:

1, ash bucket is inserted into the outlet side of tracheae, makes gas gathering mask bottom close to hopper bottom discharge port, to the pressure of material monitoring Power transmitter is located at outside ash bucket, makes it from that material washes away, fouling etc. influences, and improves service life, it is ensured that measurement data Authenticity, and then accurate judgement level of filler material state.

2, it periodically opens electrically operated valve to ventilate to ash bucket, when the air pressure signal of pressure transmitter detection is unchanged, really Determine gas gathering mask not covered by ash material, i.e., without ash material in ash bucket；When the air pressure signal of pressure transmitter detection is rapidly increased to centainly It when being worth unchanged again, determines that gas gathering mask is covered by ash material, i.e., has ash material in ash bucket and in non-ash discharge state；Work as pressure transmitter When the air pressure signal of detection is rapidly increased to certain value and slowly reduces again, determines that gas gathering mask is covered by ash material, i.e., have ash in ash bucket Expect and is in ash discharge state.

Fig. 2 is the circuit block diagram of Fig. 1；

In figure: 1- appendix, 2- gas station, 3- gas gathering mask, 4- electrically operated valve, 5- pressure transmitter, 6- electronic controller, 7- Ash bucket.

Specific embodiment

As shown in Figure 1 and Figure 2, the inlet end of Barometric bin level meter, including appendix 1, appendix 1 connects gas station 2, gas transmission The outlet side of pipe 1 tilts down, and the gas outlet setting bell mouth shape gas gathering mask 3 that Open Side Down of appendix 1, in appendix 1 Electrically operated valve 4 is arranged in pipe shaft, is located between 1 outlet side of electrically operated valve 4 and appendix in 1 pipe shaft of appendix and pressure transmitter is arranged 5, which is additionally provided with electronic controller 6, and the electrically operated valve 4 and pressure transmitter 5 pass through conducting wire and electricity respectively Sub-controller 6 connects.

When operation, electronic controller 6 is accessed into higher level's monitoring system, ash bucket 7 is inserted into the outlet side of appendix 1, makes to collect Electrically operated valve 4 is periodically opened close to 7 bottom discharge port of ash bucket in 3 bottom of gas hood.

Open electrically operated valve 4, gas station 2 into 1 ventilatory cycle of appendix, when pressure transmitter 5 detect air pressure signal without When variation, determine that gas gathering mask 3 is not covered by ash material, i.e., without ash material in ash bucket 7；

Electrically operated valve 4, gas station 2 are opened into 1 ventilatory cycle of appendix, when the air pressure signal that pressure transmitter 5 detects is fast Speed increase to certain value it is unchanged again when, determine that gas gathering mask 3 is covered by ash material, i.e., have ash material in ash bucket 7 and in non-ash discharge shape State；

Electrically operated valve 4, gas station 2 are opened into 1 ventilatory cycle of appendix, when the air pressure signal that pressure transmitter 5 detects is fast It when speed increases to certain value and slowly reduces again, determines that gas gathering mask 3 is covered by ash material, i.e., has ash material in ash bucket 7 and in ash discharge shape State.

The above are only specific embodiments of the present invention, is not intended to limit the utility model, for this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
