Through at detachable water conservancy diversion distributing device of vertical roller mill ash bucket bottom design, guide ash bucket feed back swift current to grinding roller to nibble on the material central line for return the powder and in time obtain grinding, stabilized mill brazing preform layer, improved grinding efficiency and yield.
Description
Technical field
This utility model belongs to vertical mill field, more particularly, to a kind of vertical mill equipment of building waste treatment process can
Dismounting vertical mill ash bucket returns the stable bed of material device of powder.
Background technology
Vertical mill equipment and technology come from the Germany of the twenties in 20th century, and its widespread popularity, economy and stability obtain
Arrive the proof of industrial practice, be one of first-selected energy-conservation equipment of current grinding field.Vertical mill is all based on bed-grinding machine
Reason is although have the developing history of last 100 yearses, but its version is substantially similar.
China initially introduces vertical mill, is mainly used in the grinding of the materials such as the cement slurry of cement industry, raw coal, Gypsum Fibrosum,
Due to the superiority of its high yield and low cost, gradually replace ball mill in the status of cement industry.The multi-functional and energy-conservation of vertical mill
The characteristic adaptation development of multiple industries, the field such as slag, slag, because these materials have certain moisture, in powder
Grind and during above material, need additionally to be passed through hot blast, there is the combined grinding problem of dry and wet material, the easy bonding of dry and wet material in mill
Agglomerating it will usually impact grinding machine grinding efficiency.
Knowable to the principle of vertical mill, carried by wind through the material of grinding and carry out selecting powder to Vertical Mill top powder concentrator, qualified
Fine powder goes out mill with air-flow and is collected as finished product by dust-precipitator, and underproof coarse powder falls into because of gravitational settling after being impacted by rotor of powder separator
Ash bucket, finally drops down onto mill central authorities, with the new water-containing materials feeding again by grinding.Powder fineness returned more carefully and due to sedimentation
It is oven-dried, easily causes with the water-containing materials of new feeding that bonding is agglomerating, or even cause solidification to lump because returning the hydration characteristics of powder,
Lead to migration velocity on mill for the material slack-off eventually, thickness of feed layer change fluctuation greatly, causes grinding machine vibration big, have impact on grinding machine
Grinding efficiency and operational stability.
Utility model content
The purpose of this utility model is to return, because of vertical mill ash bucket, the bed of material unstable impact grinding machine grinding that powder leads in order to reduce
The realistic problem of efficiency, this utility model devises the stable bed of material device that a kind of vertical mill ash bucket returns powder, and this device is removable
Unload formula, design is simple, simple installation easily operates.
To achieve these goals, technical solution adopted in the utility model is：
A kind of detachable vertical mill ash bucket returns the stable bed of material device of powder, including located at vertical mill ash bucket emission of baiting chute bottom
Flue-dust retainer, flue-dust retainer upper end open shape is identical with vertical mill ash bucket emission of baiting chute bottom, and flue-dust retainer upper end open size is big
In or be equal to vertical mill ash bucket emission of baiting chute bottom opening, described flue-dust retainer is welded with vertical mill ash bucket emission of baiting chute, in collection
Ash bucket lower end both sides symmetrically offer hole slot, are welded with water conservancy diversion elephant trunk at two hole slots respectively.
Open assembly reduces tapered structure to described flue-dust retainer from top to bottom.
Water conservancy diversion elephant trunk lower end pass through flange detachable be connected with cloth elephant trunk, cloth elephant trunk lower end extends to grinding roller
Grind material position of center line.
Cloth elephant trunk is connected with hanger, is connected with support between hanger and the housing of vertical mill.
The discharging end face distance mill upper level difference of described cloth elephant trunk is the arbitrary number between 150mm-200mm
Value.
The distance between described cloth elephant trunk and grinding roller are any value between 50mm-100mm.
The beneficial effects of the utility model：By designing a detachable water conservancy diversion cloth dress in vertical mill hopper bottom
Put, guiding ash bucket feed back slips to nibble on material centrage to grinding roller and ground in time so that returning powder, stabilizes the mill bed of material, improves
Mill efficiency and yield rate.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is plane graph of the present utility model.
Specific embodiment
With reference to embodiment, this utility model is described further.
Embodiment
A kind of detachable vertical mill ash bucket as depicted in figs. 1 and 2 returns the stable bed of material device of powder, including located at vertical mill
The flue-dust retainer 1 of ash bucket emission of baiting chute bottom, flue-dust retainer 1 upper end open shape is identical with vertical mill ash bucket emission of baiting chute bottom, collection
Ash bucket upper end open size is more than or equal to vertical mill ash bucket emission of baiting chute bottom opening, described flue-dust retainer and vertical mill ash bucket
Emission of baiting chute welds, and symmetrically offers hole slot in flue-dust retainer lower end both sides, is welded with water conservancy diversion elephant trunk 2 at two hole slots respectively.Institute
Open assembly reduces tapered structure to the flue-dust retainer stated from top to bottom.Pass through the detachable company of flange 3 in water conservancy diversion elephant trunk lower end
It is connected to cloth elephant trunk 4, cloth elephant trunk lower end extends to grinding roller 7 and grinds material position of center line.Cloth elephant trunk is connected with hanger,
It is connected with support 5 between hanger and the housing of vertical mill.Discharging end face distance mill 6 upper level of described cloth elephant trunk
Difference is any value between 150mm-200mm.The distance between described cloth elephant trunk and grinding roller 7 are between 50mm-100mm
Any value.
In water-containing materials such as grinding slag, slags, through grinding the outer fine powder overflowing mill 6, grinding machine top is blown to by hot blast
Portion's powder concentrator is sorted, and qualified fine powder goes out mill with air-flow and is collected as finished product, after underproof coarse powder is impacted by rotor of powder separator
Because gravitational settling falls into ash bucket, come together in taper flue-dust retainer 1 through ash bucket emission of baiting chute, have water conservancy diversion elephant trunk in its both sides symmetric design
2, by guide functions, slip via the cloth elephant trunk 4 that flange 2 connects and expect on centrage to nibbling of grinding roller 7, with the mill rotating
6 by engaging-in grinding roller 7 bottom, obtains high pressure abrasive in time, lifts yield rate.Meanwhile, the rational position of cloth elephant trunk 4 welds
Hanger, for installing bracing frame 5, its form can play the guarantor to cloth elephant trunk 4 using reinforcement welding on grinding machine inner shell
Shield and supporting role.This utility model can not only effectively prevent vertical mill ash bucket from returning powder and the new bonding in bulk feeding water-containing materials
Problem, is also beneficial to ensure that the mill bed of material is stable, lifts grinding efficiency and yield rate.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, in the art commonly
The simple change of technical staff and replace be all within protection domain of the present utility model.
