Description
Technical Field
The utility model relates to the field of multi-component micro-addition batching of powdery materials such as grains, foods and chemical industry, in particular to a multi-component batch double-bucket batching scale.
Background
Along with the diversification and refinement development of main products of grains, foods, chemical industry and the like in China, the batching scale is taken as representative equipment of positive-displacement batching, and is widely applied to various industries at present, most batching scales are single-bucket weighing hoppers, namely materials needing batching enter the weighing hoppers in sequence according to the addition sequence and the addition proportion set by a formula through respective augers, the weighing hoppers are supported on 3 gravity sensors, and after weight change is detected, the weight is converted into an electric signal, and the electric signal is sent into a weighing control instrument and is converted into digital quantity to enter for processing. When the weighing value of one material reaches a preset point, the weighing control instrument sends a signal to close the corresponding upper feeding auger, the auger starts feeding of the second material, the second material proportioning is carried out by the auger, the weighing control instrument sends a signal repeatedly until the last material proportioning is finished, the weighing control instrument sends a signal after the last feeding auger is closed, the weighing value displayed by the weighing control instrument is stable for a plurality of seconds, and after the accumulated total weight reaches the rated weight of one batch, the airtight disc valve at the lower part of the weighing hopper is opened to empty all the materials matched in the weighing hopper into the mixer at the lower part for stirring and mixing, so that the proportioning uniformity of the mixed materials is ensured. After the sensor detects that the materials in the weighing hopper are discharged, a signal is sent to enable the airtight butterfly valve to return to be closed, the weighing control instrument is reset, and the next batch of ingredients is started. The biggest problem of this kind of weighing method is that can control final every batch total dosage but to the interpolation precision of every material can not guarantee, and the accuracy of proportioning is not high. Because if one of the materials has an addition error, the addition amount of the other materials is affected, especially by factors such as the volume weight and the fluidity of the materials, the difference of the material amount in unit time from the falling of each feeding auger is large, the time difference exists between the detection of the rated weight by the sensor and the stopping of the feeding of the auger, so that a part of the materials fall from an auger outlet but are still in the air when the sensor sends out the signal, the part of the materials are not contained in the signal sent by the sensor, which is called as an 'air material', the existence of the air material is unavoidable, and the greater the height difference of the auger outlet from a weighing hopper of the batching scale is, the more the air amount is, and the greater the weighing precision is affected. Particularly, when the number of ingredients in each batch is larger and the proportion difference is larger, when the single-bucket weighing hopper is adopted to continuously add multi-component materials through the ingredient balance in an accumulated weighing mode, the air quantity generated by each auger is continuously accumulated, so that the proportion error of the materials in each batch is increased, the proportion precision cannot be ensured, and the quality of mixed products is affected. Therefore, how to accurately control the air quantity of each feeding auger in the batching scale after stopping is an important point for ensuring accurate batching.
