Abstract
A vertical pulverizer with impact breaking function is composed of machine base, wind-circulating unit, breaking-pulverizing mill mechanism, separating unit and centrifugal cone. Said wind-circulating unit under the breaking-pulverizing mill mechanism can provide airflow to the latter from the center of its bottom. The separating unit above the breaking-pulverizing mill mechanism is connected to centrifugal cone, so that the material whose granularity can not meet requirement will be pulverized again. Its advantages are simple structure, integration of breaker with pulverizer, and high breaking ratio up to more than 8000.
Description
The invention belongs to brokenly the grinding machine tool, relate in particular to fragmentation, grinding, select the powder appearance to be the broken grinding machine of one.
" grinding process and equipment " book that publishing house of Wuhan Polytechnical Univ publishes in July, 1993, introduced the vertical mill of a kind of MPS for the 67th page to 74 pages and 87 pages to 89 pages, it is made up of the mill, grinding roller, hydraulic pressure draw-bar, pressing mechanism and the powder concentrator structure that are arranged on the base, it is provided with air current spray nozzle around the mill lower limb, the powder concentrator structure is positioned at mill grinding roller top, and the material that is ground can upwards suspend with air-flow and enter the sorting mechanism sorting.This structure have in grinding machine with grinding with select powder to hold to be the characteristics of one.But, this vertical mill exists following shortcoming: because its grinding mechanism employing is mill grinding roller structure, grinding is mainly to roll, this with regard to determined processed material certain selectivity is arranged, its granularity can not be excessive, otherwise be difficult to brokenly mill, and the ratio of reduction is difficult to improve, the excessive material of granularity also will just can enter this machine grinding earlier through after the fragmentation; In addition, this vertical mill must be provided with a pressing mechanism in order to increase grinding roller pressure, makes the structure more complicated, and is all not quite convenient at aspects such as manufacturing, use, maintenances.
The purpose of this invention is to provide a kind ofly with broken, grinding with select powder to hold to be the vertical impact crushing mill of one, it is big to have the ratio of reduction, advantages of simple structure and simple.
Purpose of the present invention can be achieved by following technological approaches, vertical impact crushing mill is by support, the return air seat, broken grinding machine structure, separating mechanism and centrifugal cone are formed, the return air seat is positioned between support and the broken grinding machine structure, separating mechanism is positioned at brokenly on the grinding machine structure, separating mechanism is connected with centrifugal cone with connecting pipe, characteristics are broken that the grinding machine structure is by shell, vertical shaft, rotor and feed cavity constitute, the vertical shaft lower end is passed above-mentioned return air seat and is fixed on the support, and be connected with transmission mechanism, on the upper head plate of return air seat, have the opening that allows air communication cross around the vertical shaft, the upper end of vertical shaft is fixed on the middle part of end plate under the feed cavity, feed cavity is arranged at brokenly grinding machine structure top, feed cavity is basin shape, form by sidewall and following end plate, sidewall has charging aperture to be connected with feed hopper on the shell, the fixedly bearing block of vertical shaft is arranged on the following end plate of feed cavity, the opening that feed opening is arranged and allow air communication cross, rotor is arranged at the vertical shaft middle part, bar is arranged on the rotor, be provided with annular counterpunch board at peritrochanteric, below rotor, be provided with counterpunch board down, described separating mechanism is arranged on the feed cavity, constitute by shell and centrifugal blower, the air inlet of centrifugal blower is relative with broken grinding machine structure, the centrifugal blower air inlet forms disengagement chamber between the feed cavity, the air outlet of centrifugal blower is connected with wind pipe, other setting of broken grinding machine structure a up big and down small centrifugal cone is set, air inlet on the centrifugal cone sidewall is connected with the wind pipe of centrifugal blower, the centrifugal cone bottom is provided with closes air-valve, the top of centrifugal cone is provided with adjusting valve, above-mentioned return air seat is connected with backwind tube, this backwind tube enters centrifugal cone from the bottom of centrifugal cone and links to each other with the adjusting valve at centrifugal cone top, is positioned at backwind tube on the pipeline of centrifugal cone to be provided with opening.
From above-mentioned technical scheme as can be seen the present invention have following relatively outstanding technique effect.The rotor of broken grinding machine structure horizontally rotates, peritrochanteric has counterpunch board, formed broken mill chamber between these counterpunch boards, after material enters brokenly mill chamber, at first being connected the hammering of rotor upper plate beats, by primary fragmentation, obtained huge energy by the material that impacted, fly the impact counterpunch board with very high speed, through the counterattack effect by second-time breakage, the material of being strikeed back into fragment is rebounded, or hit once more by bar, or in flying the way, hit other material with very high speed, served as " broken grinding media " or be called " abrasive body ", form self-grinding action, the mutual strike between the material forms tertiary crushing.In said process, there is partial material can drop to down on the counterpunch board, at this moment high speed rotor rotated and bar can carry out grinding to this part material, and the distance under suitably adjusting between counterpunch board and rotor can reach satisfied grinding effect.The present invention also is provided with the return air seat in the bottom of broken grinding machine structure, top at broken grinding machine structure is provided with separating mechanism, machine can produce air-flow upwards in broken grinding machine structure and separating mechanism in the broken mill to material, to the material sorting that suspends, and product sent into the centrifugal cone sedimentation, thicker material drops to or stays brokenly in the grinding machine structure by further broken mill until becoming product.The material that constantly adds in this process has served as the process more than the new medium repetition again.Therefore, the present invention holds three kinds of functions of fragmentation, grinding, sorting for one, has greatly improved work efficiency, has accomplished to save time, saving of labor, energy-conservation; Material, is elected product one gas as to branch again and is finished to grinding from block broken simultaneously, has improved the ratio of reduction greatly, and the ratio of reduction can reach more than 8000; The present invention has also saved equipment in addition.It can also be seen that from above-mentioned technical scheme the utility model also has simple in structure, processing ease, safety, characteristics such as easy to maintenance.The production that can be widely used in cement, chemical fertilizer, industrial chemicals and various opaque products is used.
