Description
Technical field
The utility model relates to a kind of metering transmission equipments, and in particular to a kind of powder metering conveying device.
Background technique
The powder addition major way for stablizing native mixing station currently on the market is referred to as in the industry " spiral electron claims to measure ",
Its principle is: the powder in filler bin is entered in transitional storehouse by constant speed screw machine, then enters spiral by adjusting the speed screw machine
Enter blender after being measured in electronic scale.Transitional storehouse in this structure is not involved in metering, is intended merely to alleviate large capacity powder
When feed bin discharges the problem of bring arch camber, spiral electron claims to be constant speed, and conveying capacity size will lean on the speed regulation spiral of back
To adjust.The shortcomings that spiral electron claims using suspension method, acquires signal only with a tension sensor, this structure:
1. needing to pick out material to be demarcated, calibration is difficult.
Because various title bodies need to demarcate before use, which can only be claimed when nominal by spiral electron
The numerical value shown in the actual weight and computer of the material screwed out in a period of time compares, after repeated multiple times acquirement phase close values,
It just calculates and completes calibration.It needs ceaselessly to be connected to material from discharge outlet in the process, then goes to weigh.It is time-consuming and laborious, also waste object
Material.
2. mains frequency, wind-force fall ash, the trip service of helical blade fused glass inside, even helix balance etc. and can all influence
Measuring accuracy, measuring accuracy are poor.
Because one screw conveyor of the structure after tension sensor suspension plus forming, without good solid
It is fixed, so there are various influence precision in use.It is resulted in when mains frequency is unstable, wind speed is big entire
Screw machine shakes back and forth, keeps sensor output signal unstable, causes measuring accuracy poor.Existed for a long time using spiral inner wall viscous
Material problem such as nominally also results in measuring accuracy shakiness not in time.
3. since the factor for influencing measuring accuracy is more, so needing periodically to clean maintenance and calibration.
Because guaranteeing equipment measuring accuracy, the maintenance frequency of the structure is very high.It every time will be again after the completion of maintenance
Calibration, and demarcating steps are troublesome.
Therefore, a kind of new powder metering conveying device is developed, not only there is urgent researching value, it may have good warp
Benefit of helping and commercial application potentiality, where this power exactly of the invention being accomplished and basis.
