Background technology
In existing ceramic raw material Vertical Mill equipment, ceramic raw material is all directly by material-falling hopper, directly to drop on the mill end face of rotation of hopper below, wherein the ceramic raw material at close mill center is because the centrifugal force being subject to is less, be difficult to move to mill milling zone from mill center, thereby cause ceramic raw material to be piled up at mill center, affect the discharging of material-falling hopper and the operating efficiency of equipment; And the roller of existing vertical mill use, roller roller roller face is close to round and smooth light face, it is when coordinating grinding material with mill, grinding material easily produces and moves on its round and smooth light face, and when grinding material contained humidity is higher, be polished material and be easily pressed into pie, thereby it is insufficient to cause grinding material to grind; And the discharge method of existing grinding material is that the centrifugal action only producing by means of the mill that rotatablely moves carries out discharging, this material discharge method is disorderly and unsystematic, affects the flour extraction of material, has reduced equipment operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reliable, uniform blanking reasonable in design is provided, can improves the Vertical Mill equipment for ceramic raw material grinding of grinding efficiency and flour extraction.
For achieving the above object, technical scheme provided by the utility model is: a kind of Vertical Mill equipment for ceramic raw material grinding, include vertical mill shell, batch can, mill and grinding roller, it also includes the screeding device that is positioned at described batch can lower end, wherein the housing of this screeding device is tightly placed on the discharging opening shell of described batch can lower end by two connecting plates of being strained by bolt, and described in two, connecting plate is positioned at described housing two ends, it is spaced apart that the scraper plate that is positioned at described screeding device bottom is circumferential along housing bottom, and this scraper plate bottom is the non-milling zone of the taper raising up with described mill center and fits, on described grinding roller body, to have profile of tooth be the roller skin of helical teeth to uniform fold, and be formed with powder passage between the skin-deep adjacent helical teeth of described roller.
Between described vertical mill outer casing inner wall and mill, be provided with blanking channel.
Described roller skin helical teeth profile of tooth is a kind of in circular arc helical teeth, herringbone tooth, rhombus tooth, and wherein this roller skin neutrality line helical teeth transverse tooth thickness is thicker than roller skin both ends of the surface position helical teeth transverse tooth thickness.
Described roller skin helical teeth rotation direction is a kind of in left-handed or dextrorotation.
The utility model is after having adopted such scheme, its great advantage is by being provided with a screeding device in batch can discharging opening lower end, can effectively solve near the problem that ceramic raw material is piled up mill center, and adopt helical teeth to grind, increased the milling time that is polished material, and then improved percentage of damage, and because roller skin is when grinding, roller skin groundwork position is the middle helical teeth part of roller skin, suitably increase the helical teeth thickness of roller skin middle part, can improve the service life of roller skin, wearability, simultaneously under helical teeth abrasive structure, abrasive material is along the regular grinding discharge of powder channel direction forming between the skin-deep adjacent helical teeth of roller, improved flour extraction, and then increased production capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross section structure schematic diagram that screeding device of the present utility model is connected with discharging opening.
Fig. 3 is shaft of grinding roller mapping of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Referring to accompanying drawing 1 to shown in accompanying drawing 3, a kind of Vertical Mill equipment for ceramic raw material grinding described in the present embodiment, its central roll skin profile of tooth is circular arc helical teeth, rotation direction is dextrorotation, the screeding device 5 that this Vertical Mill device includes vertical mill shell 1, batch can 2, mill 3, grinding roller 4 and is positioned at batch can 2 lower ends, the discharging opening shell 2-1 that wherein the housing 5-1 of this screeding device 5 is tightly placed in described batch can 2 lower ends by the two connecting plate 5-3 that strained by bolt 5-2 is upper, and described in two, connecting plate 5-3 is positioned at the two ends of described housing 5-1.These screeding device 5 lower ends are provided with along the rounded scraper plate 5-4 spaced apart in described housing 5-1 bottom, and this scraper plate 5-4 bottom is the non-milling zone 3-1 of the taper raising up with described mill 3 centers and fits.In the time of on mill 3 end faces of ceramic raw material rotation status below batch can 2 drops to it, ceramic raw material is along with mill 3 rotates, wherein be positioned near the ceramic raw material of position, mill 3 centers because the centrifugal action being subject to is less, be difficult to move to mill 3 milling zone 3-2, and be positioned at the fixing screeding device 5 in described batch can 2 lower ends, by the scraper plate 5-4 bottom it, by being deposited in relative its ceramic raw material rotating of mill 3 center endface position annexes, to surrounding, push open gradually, the ceramic raw material being open enters into the milling zone 3-2 of mill 3 under the thrust of described scraper plate 5-4 and the comprehensive function of centrifugal force.
Due to the roller skin 4-1 of the described grinding roller 4 circular arc line helical teeth that is dextrorotation, when ceramic raw material enters into the powder passage 4-2 forming between the adjacent circular arc line helical teeth of described roller skin 4-1, ceramic raw material in powder passage 4-2 is rolled by the mill 3 being meshed with this powder passage 4-2, because the profile of tooth being meshed is helical teeth, ceramic raw material can be subject to the inside squeezing action in circular arc helical teeth side of powder passage 4-2 both sides when rolling, and then make the ceramic raw material being rolled be difficult to move outside powder passage 4-2 two sides, material is ground more abundant.While exiting gradually engagement along with the helical teeth of roller skin 4-1 and mill 3, the ceramic raw material that is positioned at accordingly powder passage 4-2 also exits and rolls thereupon, exiting the tangential direction that the ceramic raw material that rolls exits engagement along powder passage 4-2 throws away regularly, wherein mill edge is the milling zone 3-2 of outside rising gradually, the baffle plate 7 being positioned on mill milled border approaches a closed area of formation with the roller skin 4-1 of corresponding vertical mill grinding roller 4, and ceramic raw material is along corresponding powder passage 4-2 discharging.Consider that described roller skin 4-1 is in the process of rolling, the circular arc helical teeth working portion of roller skin 4-1 is mainly the circular arc helical teeth of the neutrality line annex of roller skin 4-1, and near helical teeth transverse tooth thickness thickness during design this roller skin 4-1 center line position is thicker than this roller skin 4-1 both ends of the surface position helical teeth transverse tooth thickness.The ceramic raw material being thrown out of along powder passage 4-2 drops in the blanking channel 6 being provided with between described vertical mill shell 1 inwall and mill 3, ceramic raw material after rolling enters into follow-up Vertical Mill operation through this blanking channel 6, so far completes whole ceramic raw material process of lapping.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
