Abstract
The utility model provides a drying material spraying device of ore fines. The device comprises a primary air flue; a feeding port and a discharging port are respectively arranged on one end and the other end of the primary air flue; a feeding impeller is arranged at the feeding port; a primary air inlet communicated with the primary air flue is arranged under the feeding port; the device also comprises a secondary hot air flue; and one end of the secondary hot air flue is communicated with the discharging port and a secondary hot air inlet is arranged in the other end of the secondary hot air flue. According to the utility model, in a using process, materials are uniformly fed and difficult to caking; when discharged from the discharging port, the materials have a certain speed, so just by allowing the tail end direction of the primary air flue to be consistent with the wind direction of an air classification device, it can be ensured that material entering direction is consistent with the wind direction of the air classification device; and when discharged out from the discharging port, the materials are dried at once by hot air, so an air classification effect is ensured.
Description
Technical field
The utility model belongs to technical field of mineral processing, relates to the dry material-spraying device of a kind of fine ore.
Background technology
At present, the grading device of domestic processing 0 ~ 15mm iron ore has machinery and wind classification device, wind classification device can be isolated the iron ore of 1 ~ 5mm grade from 0 ~ 5mm, but the current wind classification device particularly feed-type of horizontal wind classification device all adopts the mode of directly toppling over feed, there is pan feeding direction and the inconsistent problem of grading plant wind direction of the inhomogeneous and material of feed, affected the grading effect of wind classification device.In addition,, to fine fraction ore material, during air classification, also there is the high problem that can not be effectively separated of moisture content of material.
Utility model content
The object of utility model is the problem existing for prior art, for wind classification device provides a kind of even feeding and material pan feeding direction fine ore dry material-spraying device consistent with grading plant wind direction realized.
For this reason, the utility model adopts following technical scheme:
Fine ore is dried a material-spraying device, comprises air channel one time, and the one end in a described air channel is provided with charging aperture, the other end is provided with discharging opening, and described charging aperture place is provided with feed impeller, and charging aperture below is provided with the wind entrance being connected with air channel.
Further, the dry material-spraying device of described fine ore also comprises second heat air channel, and one end, described second heat air channel is connected with discharging opening, the other end is provided with secondary hot-air entrance.
Further, between a described wind entrance and an air channel, be connected with wind regime distribution cavity, and described wind regime distribution cavity is connected with an air channel by gas nozzle.
The beneficial effects of the utility model are: feed is even, material prevented from caking; Material has certain speed from discharging opening out time, as long as make an air channel end direction consistent with the wind direction of wind classification device, can guarantee that material pan feeding direction is consistent with grading plant wind direction; Material is subject to heated-air drying from discharging opening out time immediately, has guaranteed air classification effect; One time wind wind regime is even, has guaranteed all even synchronized ejections of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of Fig. 1.
The specific embodiment
As Figure 1-3, a kind of fine ore is dried material-spraying device, comprise air channel 1 and second heat air channel 8, the one end in an air channel 1 is provided with charging aperture 2, the other end is provided with discharging opening 3, charging aperture 2 places are provided with feed impeller 4, charging aperture 2 belows are provided with between 5, wind entrances 5 of a wind entrance of being connected with air channel 1 and an air channel 1 and are connected with wind regime distribution cavity 6, and wind regime distribution cavity 6 is connected with an air channel 1 by gas nozzle 7; 8 one end, second heat air channel are connected with discharging opening 3, the other end is provided with secondary hot-air entrance 9.
During use, discharging opening 3 of the present utility model is connected with the feeding mouth of wind classification device, and notes making the direction of air channel 1 latter end consistent with the wind direction of wind classification device.Then by charging aperture 2 feeds, under feed impeller 4 rotary actions, can guarantee feed process evenly and avoid caking.Material is subject to the wind-force effect by gas nozzle 7 wind out after entering an air channel 1, is constantly blown to discharging opening 3, is subject to again the dry of the hot blast that blows out from second heat air channel 8 at discharging opening 3 places.Setting due to origin distribution cavity 6 and gas nozzle 7, can make a wind evenly enter in an air channel 1, has guaranteed the even ejection of material.
