Technical field
The utility model relates to a kind of powder collecting bin, specifically the automatic control device used of filler bin.
Background technology
In powder production such as cement or powder processing industry, the powder of producing is delivered to through wind-force usually and stores in the filler bin, after powder gets into filler bin, carries the air-flow of usefulness to discharge from the exhaust outlet of filler bin upper end.Existing filler bin is an enclosed construction all, and the judgement of powder amount leans on level detector to measure usually in the storehouse, and the level detector operated by rotary motion is at the inwall of filler bin.Blocking rotary type level-sensing device for example, it has a turning unit, when powder buried the material level timing, judges the powder position and is higher than level-sensing device thereby turning unit can't normally rotate.Therefore, the mode that level-sensing device is set can only be judged powder and be positioned on the level-sensing device or under the level-sensing device, can't accurately draw the weight that powder amount height also can't be known the sub-material amount, is unfavorable for that control produces.Simultaneously, a part of powder collecting bin is provided with safety valve, and when the filler bin fault, safety valve is opened, and carries a large amount of powders and discharges, and powder is produced in waste.Simultaneously, when powder was full of filler bin, the powder load wagon also was in the feed state, and waste powder and power are provided with by-pass valve control on the powder load wagon, restricted by the load wagon position, used inconveniently, and that can not in time control powder advances the powder progress.
The utility model content
The utility model provides technical matters to be solved to provide the automatic control device that filler bin is used, and can accurately measure the weight and the height of the cement powders in the feed bin, and the current state of monitoring safety valve, control feed progress.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: the automatic control device that filler bin is used, be provided with warehouse, and the bottom of warehouse is an infundibulate; Its bottom is provided with discharging opening, and the sidewall in the warehouse is provided with feed pipe, and feed pipe is provided with by-pass valve control; The warehouse end face is provided with safety valve and pressure sensor; Outside warehouse, also be provided with controller, vertically evenly distributed on the sidewall in the warehouse have a plurality of level detectors, and the madial wall of the funnel shaped part of warehouse is provided with weighting apparatus; The outer support of warehouse is provided with the filler bin weighting apparatus; Be provided with in the safety valve near switch, be connected with controller near the signal output of switch, pressure sensor, weighting apparatus, filler bin weighting apparatus and level detector, the signal output of controller is connected with by-pass valve control.
The described warehouse of the utility model also is provided with telltale outward, and telltale is connected with controller.
The contact position of described weighting apparatus of the utility model and warehouse is provided with access door.
The beneficial effect of the utility model is: the powder amount in the weighting apparatus that is provided with in the warehouse can be measured and deliver from godown, and be convenient to control and produce.Pressure sensor on the warehouse end face is measured accurately, gathers pressure signal, and the pressure data in the filler bin is transferred on the read out instrument after handling through controller, demonstrates the pressure of present filler bin.Level-sensing device on the warehouse sidewall is measured the height at current powder amount place, shows through telltale again, and convenient control is produced.Simultaneously, telltale shows the state of working as of safety valve, prevents the filler bin fault, and safety valve is opened, the waste powder, and powder is full in detecting filler bin, and controller is passed to by-pass valve control with signal, makes the by-pass valve control SELF CL, avoids waste and accident.
