Abstract
The utility model discloses a multi-impeller air-current mill. The multi-impeller air-current mill comprises a barrel body, wherein a grading upper body is arranged at the upper end of the barrel body; a grading device is arranged on the grading upper body; the grading device comprises a plurality of grading impellers which are arranged in the grading upper body; and the plurality of the grading impellers are respectively connected with a power drive device in a transmission manner. According to the multi-impeller air-current mill, the plurality of grading devices are arranged on the large-capacity crushing barrel and are organically combined to form an air flow crushing device with appropriate fineness and matched capacity. Meanwhile, large capacity and high fineness can be realized, flow filed matching is reasonable and smooth, and the energy-saving effect is remarkable.
Description
Technical field
The utility model relates to a kind of no medium disintegrating apparatus, relates to specifically a kind ofly can taking into account under the condition of high fineness the leafy airflow milling of taking turns that realizes that big production capacity is pulverized.
Background technology
Airflow milling is a kind of no medium disintegrating apparatus, does not have medium pollution in the crushing process, thereby has guaranteed the purity of raw material, and can disposable realization high fineness is pulverized, and uses extensively day by day, and has proposed the requirement of big production capacity.The operation principle of airflow milling is made up of pulverizing, two links of classification in essence, wherein pulverizing is that raw meal is broken into the compound that granularity mixes, and the function of classification is that the material that reaches fineness is in time shifted, the material that does not reach fineness continues to stay in the machine until being crushed to fineness, just have only pulverizing, classification to mate mutually, could constitute the rational airflow milling of a cover.
Concerning pulverizing part can production capacity do very big, but for the classification part, it is very big that single grading wheel production capacity is difficult to do, reason is the influence that is subjected to structure, production capacity, fineness, grading wheel diameter three are the factors of being mutually related, and experience shows: production capacity is more big, requires big grading wheel, and big grading wheel can make the product chap, and this just runs counter to the requirement of the high fineness of big production capacity.Here it is has limited the bottleneck that airflow milling that current this single grading wheel joins single crush box develops to the direction of the high fineness of big production capacity.
The utility model content
Problem to be solved in the utility model provides a kind of leafy airflow milling of taking turns that can take into account big production capacity, high fineness simultaneously.
In order to address the above problem, the utility model by the following technical solutions:
A kind of leafy airflow milling of taking turns, comprise cylindrical shell, the upper end of cylindrical shell is equipped with the classification upper body, and classification is equipped with grading plant on the upper body, described grading plant comprises several classifying turbines that are installed in the classification upper body, and several classifying turbines are in transmission connection with Power Drive Unit respectively.
Below be the utility model for further improvement of these options:
Several classifying turbines evenly distribute in the classification upper body ringwise.
Further improve: Power Drive Unit comprises that several are fixed on the classification upper body and several classifying turbines motor one to one, and a wherein end of each classifying turbine is in transmission connection with corresponding motor respectively.
Further improve: the position near the lower end on the cylindrical shell is equipped with feed pipe, and reducing mechanism is installed in the cylindrical shell, and the top of classification upper body is equipped with discharge nozzle.
Further improve: the other end of described each classifying turbine is connected with the recoil air-casing respectively, and described recoil air-casing is communicated with discharge nozzle.
Further improve: described reducing mechanism comprises several pulverizing nozzles that are installed on the cylindrical shell, and several are pulverized nozzles and evenly distribute ringwise on cylindrical shell.
Further improve: the outside of cylindrical shell is equipped with the cylinder that is communicated with source of the gas, and several are pulverized nozzle and are communicated with cylinder respectively.
During work, raw material enters cylindrical shell from feed pipe, high velocity air is pulverized nozzle by several and evenly raw material is pulverized, owing to be communicated with air-introduced machine on the discharge nozzle, powder after the pulverizing upwards enters grading plant under the attraction of air-introduced machine, after powder entered grading plant, several classifying turbines carried out classification to powder simultaneously, qualified fines after the classification flows out from discharge nozzle after passing the recoil air-casing, and the coarse fodder after the classification returns cylindrical shell again and pulverizes again under the effect of gravity.
The utility model arranges a plurality of grading plants on the big pulverizing cylindrical shell of production capacity, organic assembling becomes that a cover fineness is suitable, the air flow crushing device of production capacity coupling, can realize big production capacity and high fineness simultaneously, and the flow field coupling is reasonable, smooth and easy, and energy-saving effect is remarkable.
The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment
Embodiment, as shown in Figure 1, a kind of leafy airflow milling of taking turns comprises cylindrical shell 6, and the position near the lower end on the cylindrical shell 6 is equipped with feed pipe 5, and the lower end of described cylindrical shell 6 is equipped with base 1, and the centre position of cylindrical shell 6 is equipped with the peep hole made from transparent material 4; Be used for observing the pulverizing situation of raw material in the cylindrical shell 6.
In the cylindrical shell 6 reducing mechanism is installed, the upper end of cylindrical shell 6 is equipped with classification upper body 7, on the classification upper body 7 grading plant is installed, and the top of classification upper body 7 is equipped with discharge nozzle 11.
Described reducing mechanism comprises several pulverizing nozzles 2 that are installed on the cylindrical shell 6, and several are pulverized nozzles 2 and evenly distribute ringwise on cylindrical shell 6.
The outside of cylindrical shell 6 is equipped with the cylinder 3 that is communicated with source of the gas, and several are pulverized nozzle 2 and are communicated with cylinder 3 respectively.
As shown in Figure 2, described grading plant comprises several classifying turbines 9 that are installed in the classification upper body 7, and several classifying turbines 9 evenly distribute in classification upper body 7 ringwise, and several classifying turbines 9 are in transmission connection with Power Drive Unit respectively.
Power Drive Unit comprises that several are fixed on the classification upper body 7 and several classifying turbines 9 motor 8 one to one, and a wherein end of each classifying turbine 9 is in transmission connection with corresponding motor 8 respectively.
The other end of described each classifying turbine 9 is connected with recoil air-casing 10 respectively, and described recoil air-casing 10 is communicated with discharge nozzle 11.
During work, raw material enters cylindrical shell 6 from feed pipe 5, high velocity air is pulverized nozzle 2 by several and evenly raw material is pulverized, owing to be communicated with air-introduced machine on the discharge nozzle 11, powder after the pulverizing upwards enters grading plant under the attraction of air-introduced machine, after powder enters grading plant, several classifying turbines 9 carry out classification to powder simultaneously, qualified fines after the classification passes recoil air-casing 10 backs and flows out from discharge nozzle 11, and the coarse fodder after the classification returns cylindrical shell 6 again and pulverizes again under the effect of gravity.
