Description
Technical field
The present invention relates to a kind of feed arrangement of horizontal vortex type powder concentrator.
Background technology
The characteristics such as horizontal vortex type powder concentrator is used for cement industry or other industry is carried out classification to granular material, has classification efficiency high, and the material handling amount is large, and the material footpath is easy to adjust.The feeding manner of existing level vortex powder separator is the pipe of input with the feeding of the material behind grinding powder concentrator, material is fallen on the rotor of powder separator of High Rotation Speed from pipe of input, under centrifugal action, material is by the spreading disk of rotation and the rotor of throwing to guide vane under the high degree of dispersion state that acts on of the buffer board of fixing, and material carries out sorting in the air-flow of rotation.Because being the rotor by High Rotation Speed, disperses material, in order to disperse this partial material, the power of spindle motor need to be increased significantly, cause canonical loading high and cause that equipment failure rate is high, also increased manufacture difficulty and the manufacturing cost of rotor of powder separator simultaneously.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of feed arrangement of horizontal vortex type powder concentrator, the material that enters wherein effectively can be disperseed, material after effectively disperseing carries out sorting by rotor etc. again, reduce the power of spindle motor, avoid canonical loading high and cause that equipment failure rate is high, also reduce manufacture difficulty and the manufacturing cost of rotor of powder separator simultaneously.
For solving the problems of the technologies described above, the feed arrangement of a kind of horizontal vortex type powder concentrator of the present invention, comprise and be installed in the multilayer bulk material device in the powder concentrator primary air nozzle and be installed in atomising device between multilayer bulk material device and the rotor, described multilayer bulk material device is comprised of shell and the polylith dividing plate that is arranged on enclosure, every dividing plate upper end is concordant with the shell upper end, dividing plate is separated into a plurality of rectangular channels with shell, each rectangular channel length reduces from left to right successively, the shortest rectangular channel lower end is positioned at powder concentrator primary air nozzle upper surface, described multilayer bulk material device upper part is exposed at outside the powder concentrator primary air nozzle upper surface, the rhombus foundry goods that described atomising device is opened layout by three to four misarrangements consists of, the upper end of described rhombus foundry goods is positioned at the inner top of powder concentrator primary air nozzle, and the lower end is positioned at the inner bottom part of powder concentrator primary air nozzle.
Described rhombus foundry goods interior angle is 60 degree, the long-diagonal of first row rhombus foundry goods is identical with the air intake direction, the long-diagonal of second row rhombus foundry goods and air intake perpendicular direction, and second row rhombus foundry goods can block the space of first row rhombus foundry goods, the 3rd row's rhombus foundry goods distributes identical with first row, and the 4th row's rhombus foundry goods distributes identical with second row.
When material enters primary air nozzle from the multilayer bulk material device, because it is different that multilayer is advanced the discharging opening height of bulk material device, guaranteed that material evenly distributes on the perpendicular end surface of air inlet, after carrying wind of material and atomising device multiple impacts secretly material is atomized, increased the decentralization of material, material after effectively disperseing carries out sorting by rotor etc. again, improved the grinding efficiency of powder concentrator, because material does not disperse by the rotor of High Rotation Speed, reduced the power of spindle motor, avoid canonical loading high and cause that equipment failure rate is high, also reduced manufacture difficulty and the manufacturing cost of rotor of powder separator simultaneously.
Description of drawings
Fig. 1 is that the feed arrangement of a kind of horizontal vortex type powder concentrator of the present invention is installed in the structural representation on the horizontal vortex type powder concentrator, and Fig. 2 is the top view of Fig. 1, and Fig. 3 is the detailed structure schematic diagram of multilayer bulk material device among Fig. 1.
1. powder concentrator primary air nozzles among the figure, 2. multilayer bulk material device, 3. atomising device, 4. shell, 5. dividing plate.
The specific embodiment
Fig. 1, Fig. 2, among Fig. 3, a kind of feed arrangement of horizontal vortex type powder concentrator, comprise and be installed in the multilayer bulk material device 2 in the powder concentrator primary air nozzle 1 and be installed in atomising device 3 between multilayer bulk material device 2 and the rotor, described multilayer bulk material device 2 is comprised of shell 4 and the polylith dividing plate 5 that is arranged on shell 4 inside, every dividing plate 5 upper ends are concordant with shell 4 upper ends, dividing plate 5 is separated into a plurality of rectangular channels with shell 4, each rectangular channel length reduces from left to right successively, the shortest rectangular channel lower end is positioned at powder concentrator primary air nozzle 1 upper surface, described multilayer bulk material device 2 upper parts are exposed at outside powder concentrator primary air nozzle 1 upper surface, the rhombus foundry goods that described atomising device 3 is opened layout by three to four misarrangements consists of, the upper end of described rhombus foundry goods is positioned at the inner top of powder concentrator primary air nozzle 1, and the lower end is positioned at the inner bottom part of powder concentrator primary air nozzle 1.
Described rhombus foundry goods interior angle is 60 degree, the long-diagonal of first row rhombus foundry goods is identical with the air intake direction, the long-diagonal of second row rhombus foundry goods and air intake perpendicular direction, and second row rhombus foundry goods can block the space of first row rhombus foundry goods, the 3rd row's rhombus foundry goods distributes identical with first row, and the 4th row's rhombus foundry goods distributes identical with second row.
