Abstract
The utility model provides a feeding device with automatic air lock, which belongs to the technical field of crushing and processing ores, and solves the defects in the prior feeding devices that material blockage easily caused during the material baiting process inclines to trigger stone blockage at gaps and cause abrasion of rotor blades during the friction of the stone and the rotor blades. Thefeeding device is arranged in a vertical section of a feeding channel of a grinder and comprises a body, wherein the body takes the shape of a funnel with gradually reduced size from top to bottom, and a plurality of occulting bars arranged in a step-like manner from top to bottom are fixedly connected on the inner wall of the body. To improve the air lock effect, a plurality of such feeding devices can be arrayed vertically and mounted into the vertical section of the feeding channel of the grinder. The feeding device has simple and light structure, low probability of abrasion, and convenient maintenance.
Description
Technical field
The utility model belongs to ore and pulverizes processing technique field, relates to a kind of drawing-in device, but particularly a kind of drawing-in device of automatic locking wind.
Background technology
Because inner during vertical grinder work is the totally-enclosed negative pressure state, outer gas stream can not enter, in order to avoid influence the internal gas flow rotation direction.At present,, generally adopt the lock feeding machine of corresponding power, reach grinding machine charging and lock wind function according to the vertical grinder size.It is 7.5KW lock feeding machine that diameter 1700mm grinding machine adopts power.This feeding machine rotates by its rotor blade of 7.5KW driven by motor, reaches feed door, utilizes rotor blade lock wind simultaneously.
But there are two big critical defects in actual applications in this technology.The first, material rotates in the blanking process by rotor blade the putty phenomenon very easily takes place.Because must have certain interval between rotor blade and the shell, and the multicomponent building stones are not of uniform size, are very easy to cause block building stones in the gap, cause feeding machine to jump and stop, stop and make whole production line jump.Not only influence ordinary production, also increase the power consumption of machine start-stop greatly.The second,, wear and tear with very easily causing rotor blade in the rotor blade friction process because building stones hardness is big.And existing feeding machine dismounting is complicated, heavy, and high-altitude maintenance difficulty is big, and is dangerous high.
Summary of the invention
The purpose of this utility model is at existing grinding machine frequency putty and feeding machine rotor blade problem easy to wear when using the charging of lock feeding machine, and has proposed a kind of drawing-in device that utilizes Flow of Goods and Materials to reach self lock wind effect.
The purpose of this utility model can realize by following technical proposal: a kind of drawing-in device of automatic locking wind, be arranged in the vertical section of grinding machine feeding-passage, it is characterized in that, described drawing-in device comprises body, body is the diminishing funnel-form of size from top to down, is fixed with the some blend stops that are step-like arrangement from top to down on the inwall of body.
For increasing lock wind effect, can simultaneously several drawing-in devices be installed in the upper and lower order in the vertical section of grinding machine feeding-passage.Material enters from the big end of body, utilizes the cushioning effect of body space structure wide at the top and narrow at the bottom and blend stop, slows down the material falling speed and relies on material itself that body is blocked up and down, finishes lock wind.
In the drawing-in device of above-mentioned a kind of automatic locking wind, described body is rectangle in two ends up and down, is equipped with above-mentioned blend stop on the body two opposite groups inwall.
In the drawing-in device of above-mentioned a kind of automatic locking wind, described body two ends up and down is circular, and above-mentioned blend stop is circular arc and circumferential array setting.The body upper end is square or circular shape with the coupling feeding-passage.
In the drawing-in device of above-mentioned a kind of automatic locking wind, the setting that is inclined upwardly of described blend stop.Form a groove between blend stop and the inner body wall, temporary for material.
Compared with prior art, the drawing-in device of this automatic locking wind is to utilize the funnel principle, the material self-locking, and lock wind effect is obvious, and essence ground solved a frequent putty difficult problem, and lock feeding device is simple in structure, light and handy, and not easy to wear, maintenance makes things convenient for.Owing to solved a putty difficult problem, the grinding machine operation is steady continuously, and unit-hour output significantly improves.

Fig. 2 is the structural representation of lock feeding bucket in the drawing-in device of this automatic locking wind among the embodiment 1.
Among Fig. 1,1, body; 2, feeding-passage; 3, blend stop; 4, groove.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment one
As shown in Figure 1, the drawing-in device of this automatic locking wind is arranged in the vertical section of grinding machine feeding-passage 2, comprise a body 1, body 1 is the diminishing funnel-form of size from top to down, is fixed with the some blend stops 3 that are step-like arrangement from top to down on the inwall of body 1.Blend stop 3 setting that is inclined upwardly, and form groove 4 between body 1 inwall.In the present embodiment, the two ends up and down of body 1 are rectangle, are equipped with above-mentioned blend stop 3 on the body 1 two opposite groups inwall.
For increasing lock wind effect, two identical bodies 1 install in the upper and lower order in the vertical section of grinding machine feeding-passage 2.Material enters from the big end of body 1, utilizes body 1 space structure wide at the top and narrow at the bottom and the cushioning effect of blend stop 3 and groove 4, slows down the material falling speed and relies on material itself that body 1 is blocked up and down, finishes lock wind.
Embodiment two
Two ends are for also being circular about in the of 1 for body, and with the feeding-passage 2 of coupling respective shapes, above-mentioned blend stop 3 is circular arc and circumferential array setting.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
