Abstract
The utility model discloses processing equipment for powder coal, and in particular relates to a raw material vertical mill. The utility model provides a raw material vertical mill capable of automatically sucking back a material. The raw material vertical mill comprises a mill barrel, and further comprises a material collecting box and a recycle pipeline, wherein a slag discharge opening is formed in the lower part of the mill barrel; the feed opening of the material collecting box is communicated with the slag discharge opening; the lower end of the recycle pipeline is inserted into the material collecting box, the upper end of the recycle pipeline is inserted into the mill barrel, and a valve is arranged on the recycle pipeline; the material collecting box can collect discharged impurities and the material; when the impurities are cleaned up, the material can be sucked back into the mill barrel via the recycle pipeline utilizing the negative-pressure environment of the mill barrel, so that the burden of manual feeding is relieved, the work efficiency is increased, and additional energy is not required; a separating net can be arranged in the material collecting box to primarily separate the material and the impurities, so that follow-up work is reduced.
Description
Technical field
The utility model relates to a kind of coal dust process equipment, especially a kind of raw material vertical-grinding.
Background technology
In the process of coal dust, the raw material vertical-grinding often using at present, this mill does not configure external circulating system.Its operation principle: rotate through motor, reductor band movable grinding disc, material is fallen mill central authorities through feed opening, under the effect of centrifugal force, material moves and is subject to rolling of grinding roller to mill edge, material after pulverizing leaves mill, the air-flow being made progress at a high speed brings to the separator with Vertical Mill one, and meal returns to mill grinding again after separator; Fine powder goes out mill with air-flow, under collecting, becomes product in the dust arrester installation of system.Under normal circumstances, high velocity air through the nozzle ring at mill edge can blow afloat material, and metal and other impurity of allowing to be again mixed in material fall into scraper plate chamber from nozzle ring, through scraper plate, removes to the process outside mill scum, for Vertical Mill, scum is a kind of normal phenomenon.When discharging foreign matter, partial material falls into scraper plate chamber thereupon together, is expelled to outside mill.
In the production process of Vertical Mill, through outer row, mouthful the scum material of discharging is more (is generally 400～500kg in per tour, in the time of at most, surpass 1000kg), need manually material to be packed into handcart or loading machine, pour in the pre-homogenizing heap of the circle canopy of distance field 500m left and right.This will take a large amount of manpowers and time, and not only labour intensity is large, and plant environment is caused to great pollution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of raw material vertical-grinding that can automatically suck back material.
The utility model solves the raw material vertical-grinding that its technical problem adopts, and comprises grinding mill barrel, and the bottom of grinding mill barrel is provided with slag-drip opening, also comprises Material collecting box for harvesting and recovery channel, and the charging aperture of described Material collecting box for harvesting is connected with slag-drip opening; The lower end of described recovery channel is inserted in Material collecting box for harvesting, and upper end is inserted in grinding mill barrel, and is provided with valve on recovery channel.
Further, also comprise separate mesh, described separate mesh is arranged in Material collecting box for harvesting and Material collecting box for harvesting is divided into two-layer up and down, and the charging aperture of described Material collecting box for harvesting is arranged on upper strata, and the lower end of described recovery channel is inserted into lower floor.
Further, described valve arranges on recovery channel and near Material collecting box for harvesting.
The beneficial effects of the utility model are: Material collecting box for harvesting can be collected impurity and the material of discharge, after removal of contamination, utilize the subnormal ambient of grinding mill barrel, make material suck-back from recovery channel enter grinding mill barrel, so just alleviated the burden of hand stock, improve operating efficiency, but also do not needed extra energy.In Material collecting box for harvesting, separate mesh can also be set, utilize the separate mesh can initial gross separation material and foreign material, reduce follow-up work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Parts, position and numbering in figure: grinding mill barrel 1, Material collecting box for harvesting 2, recovery channel 3, valve 4.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises grinding mill barrel 1, and the bottom of grinding mill barrel 1 is provided with slag-drip opening, also comprises Material collecting box for harvesting 2 and recovery channel 3, and the charging aperture of described Material collecting box for harvesting 2 is connected with slag-drip opening; The lower end of described recovery channel 3 is inserted in Material collecting box for harvesting 2, and upper end is inserted in grinding mill barrel 1, and is provided with valve 4 on recovery channel 3.A recovery channel is set on grinding mill barrel 1 shell, and it is inner that grinding mill barrel is inserted in upper end, and height, at grinding roller middle position, stretches into grinding mill barrel, and for the material impact that prevents from entering in mill chamber stretches into the recovery channel in mill, recovery channel 3 should not extend through spout ring.Recovery channel 3 lower ends are connected with an outer row mouthful Material collecting box for harvesting 2, in recovery channel 3 lower ends, near Material collecting box for harvesting 2 places, a valve 4 are set, and overhead highly about 1.2m, is convenient to Field Force and opens and closes.During recovered material, first remove outer row mouthful and come the metallic foreign body in Material collecting box for harvesting 2, then open valve 4, utilize the negative pressure of mill Nei Yue-7000Pa, material collection in Material collecting box for harvesting 2 is returned to mill, after recovery finishes, valve-off 4, avoids grinding interior negative pressure and declines, and affects raw mill and normally moves.Said structure does not need extra power source, adopts original power, and this is convenient when recovered material.
In order to alleviate the work of separating metal foreign matter, also comprise separate mesh, described separate mesh is arranged in Material collecting box for harvesting 2 and Material collecting box for harvesting 2 is divided into two-layer up and down, and the charging aperture of described Material collecting box for harvesting 2 is arranged on upper strata, and the lower end of described recovery channel 3 is inserted into lower floor.Separate mesh can adopt magnetic material, and the stainless (steel) wire of magnetic conduction for example, to adsorb certain metal.Can alleviate the burden of later separation metal like this.
