Abstract
The utility model relates to a supply screening compartment device that tube mill used, the barrel has remain suitable distance between its preceding comb board and sieve to adopt the baffle to fall into a plurality of independent cavities with space between the two, during the screening operation, the probability that the thin material that reaches specific requirement granularity in each cavity was filtered and is passed through will obtain the increase. In addition, a bidirectional material guide cone is arranged at the rotary center of the front bin, and can guide coarse particle materials which are not screened to pass through to return to the front bin in time. The device overcomes the defect of low screening efficiency of the existing screening compartment device. After the tube mill uses the device, the production capacity can be improved, and the unit power consumption of material grinding can be reduced.
Description
Technical field
The utility model relates to a kind of for the inner screening partition device for barn that uses of tube mill, and this device is particularly useful for the used tube mill of cement grinding industry.
Background technology
The general action of tube mill partition device for barn is that grinding operation in the grinding mill barrel is divided into a plurality of independent bins, make the abrasive body of different size separate operation, big specification abrasive body is used for the broken thick material in preceding storehouse, and the small dimension abrasive body is used for the thin material of back storehouse grinding, reaches the purpose that improves mill efficiency.Early stage partition device for barn is an individual layer grate plate structure, form by a fan-shaped grate plate of circle and central ventilation plate, material mainly relies on gravity to cause the thrust of generation and is flowed toward lower by eminence, because being subjected to partition panel hinders, the translational speed of material is subjected to suppressing significantly, thereby mill efficiency is difficult to be greatly improved.Occurred double-deck partition device for barn afterwards, and mainly be made up of one deck grate plate and one deck blind plate, between also has lifting blade and guide cone.Preceding storehouse material is just kicked up by lifting blade and is entered Hou Cang through the guide cone by after the grate plate.This double-deck partition device for barn can force preceding storehouse material to enter Hou Cang, and the influence of the not material feeding potential difference that flows of material between two storehouses can realize that material is moved toward eminence by lower, thereby improve the efficient of tube mill to a certain extent.For the further mill efficiency that improves grinding machine, the domestic in recent years double-deck partition device for barn that band screening function occurred, this device has increased one deck thin sieve plate at the preceding grate plate back side of former common double-deck partition device for barn, and the comb seam width of thin sieve plate is generally about 3mm.It can screen the thin material of granularity less than sieve plate comb seam width, and makes it enter the little abrasive body continuation grinding that next storehouse acceptance requirements adapts with it.At the bigger characteristics of front and back two storehouse raw meal particle size difference, the focus in two storehouses to be divided the work specially, promptly preceding storehouse adopts big specification abrasive body emphasis to be responsible for broken function, and back storehouse adopts little abrasive body emphasis to be responsible for the grinding function.Owing to enter back storehouse raw meal particle size little (usually less than 3mm), can adopt miniature little steel section as abrasive media in the storehouse, back, material is realized sufficient abrasive action, make finish fineness thinner than the tube mill that adopts common partition panel, therefore adopt the tube mill of this band screening function partition device for barn to be called as the high yield Super-fine grinder, compare with the tube mill that adopts common partition device for barn and to have certain Increasing Production and Energy Saving effect really, under equal conditions unit-hour output can improve about 10%.Existing this screening partition device for barn weak point is that its sieving actoion can't give full play to, and can not be in time granularity be screened less than the comb material of seam width of sieve plate.Although double-deck partition device for barn has the function of forcing material to pass through, because the sieve plate that increases newly comb seam width is less, 1/2 of not enough usually original grate plate comb seam width, so the speed that material screening passes through has been subjected to suppressing significantly.Owing to be close to the back side of preceding grate plate, make that effective work area minimizing of sieve plate is more again, the screened also corresponding minimizing to some extent of chance that enters the storehouse, back of qualified material that granularity is combed and stitched less than sieve plate.The result causes small particles material to be detained in preceding storehouse, influences effective performance of preceding storehouse big abrasive body impact grinding effect, thereby has weakened the effect of tube mill Increasing Production and Energy Saving.
Summary of the invention
The purpose of this utility model provides a kind of new screening partition device for barn, and it can improve screening efficiency, makes granularity in the preceding storehouse can be in time screened come out and send into storehouse, back, the purpose of realization grinding machine Increasing Production and Energy Saving less than the comb thin material of seam width of sieve plate.
The purpose of this utility model is achieved in that on the basis of common screening partition device for barn, before script is fit together grate plate with sieve plate along the tube mill drum shaft to separate, both keep appropriate distance, this distance is stitched width and is advisable to be slightly larger than preceding grate plate comb.After grate plate was separated with sieve plate, former double-deck partition device for barn just developed and is three-decker, and the inner space is become two-layer by one deck.In the newly-increased space of this one deck between preceding grate plate and the sieve plate, radially arrange some roads dividing plate, should just be divided into a plurality of independently screening operation chambers in the new space that forms, unidirectional burden-guiding cone structural reform simultaneously that the original end in middle part is big, that the other end is little is a two-way guide cone small in ends, broad in the middle.This maximum cylindrical place, two-way guide cone middle part, promptly the boundary position of two conical surfaces is connected with sieve plate, and the both sides conical surface is fixedlyed connected with screening chamber dividing plate, discharging chamber lifting blade respectively.
After adopting technique scheme, the comb of sieve plate seam just no longer is subjected to blocking of preceding grate plate, makes effective work area of sieve plate be multiplied, and the chance that material is sized also obtains corresponding increase.Simultaneously a plurality of chambers that independently sieve have been formed owing to setting up dividing plate, these screening chambers are except carrying out screening operation as usual in the tube mill cylindrical shell is material bed, difference is that it has also brought following new beneficial effect, promptly sieve the chamber left material bed after, the material that is retained in the screening chamber interior can also continue to accept screening to be handled, effect by wind-force in grinding, fine grained leave material bed with the screening chamber when being kicked up, the easier seam by the sieve plate comb enters Hou Cang, and the coarse granule material that those are together kicked up relies on the effect of gravity to slide to two-way guide cone under dividing plate, returning preceding storehouse by two-way guide cone guiding continues to accept broken, those are sized the small particles material that passes through and are then kicked up by lifting blade, and grinding is accepted in the storehouse after lifting blade glides by two-way burden-guiding cone introducing.
