Description
Technical field
The utility model relates to the pulverizer technical field, relates in particular to R﹠D institutions such as industry, agricultural, factories and miness, medical and health, coal, geology carry out pulverization process to pledges such as various plants, soil, Sha Kuang, grains micromill.
Background technology
The miniature high-speed pulverizer is widely used in R﹠D institutions such as industry, agricultural, factories and miness, medical and health, coal, geology to pledge pulverization process such as various plants, soil, Sha Kuang, grains at present.Its adopts ultrahigh speed monophase machine as power, once only needs 1 minute just the various various samples of pulverizing that need can be ground to form 50-200 purpose powder, not only evenly but also lossless.Miniature high-speed pulverizer optimum crushing quantity is the 50-500 gram, is laboratory mini-plant commonly used.
Yet pot experiment is often done by the R﹠D institution that with the plant is research object, each sampling amount is through being everlasting below 5 grams, about about 4 grams of minimum crushing quantity of the commonly used miniature high-speed pulverizer in market such as FW-80 type pulverizer, this has just caused the unmatched problem of crushing quantity that needs to pulverize sample and pulverizer: the fineness that sample size causes pulverizing does not very little reach the pulverizing requirement, both made and prolonged the pulverizing time, the raising of pulverizing is also more limited, does not still reach the desired fineness of experiment.Pulverize experiment with the model for the FW-80 pulverizer, sample is respectively the plant stem-leaf of 5g, 4g, 3g, 2g, 1.5g, 1.0g, and the relevant crush test results of sample is as follows:
1, reduces along with sample size, reduce gradually less than the mass fraction of 0.5mm grade, because the sample of 1.5g and 1.0g very little, have only 1% less than the mass fraction of 0.5mm grade, just reach 30% and 24% after increasing by 60 seconds pulverizing time.
2, reduce along with sample size, raise gradually greater than the mass fraction of 1.0mm grade, just be reduced to 56% and 61% after increasing by 60 seconds pulverizing time.
3, since residue in a large number greater than 1.0mm grade sample by hand method grind, except the used hand lapping time of 5g sample size is 4 ' 50 〞, the hand lapping time of other sample is 18 ' more than.
By calculating like this, everyone per hour can only pulverize 3 samples at most.By 8 times each workday calculating every day, to the plant sample less than 5g, can only pulverize 24 for each person every day.And the fineness after pulverizing does not often reach the requirement of scientific research.
Generally for the fineness that guarantees to pulverize have to adopt scissors to shred back mortar hand lapping for the pulverizing of a small amount of plant sample, still lost labor comparatively, and inefficiency.
Therefore, at above deficiency, the utility model provides the agri-scientific research pulverizer.
