Abstract
The utility model relates to a chute airlock, which mainly comprises a conveying pipe which is disposed slantingly. A rotary pin is arranged on the upper inner wall of the conveying pipe, an air baffle is arranged on the pin, and the air baffle is the same as the vertical section of the conveying pipe in shape. When no stone enters, the rotary air baffle disposed inside the slanting conveying pipe can fit with the inner wall of the conveying pipe to lock air and prevent external flow from coming in. When stones enter the conveying pipe, the air baffle can be opened anytime and opening degree varies with feeding quantity, so that air leakage due to overlarge opening degree is avoided, and entry failure of the stones due to too small opening degree is avoided. In addition, the air baffle is free to swing and high in impact resistance, and the service life of the air baffle can be prolonged; and the shape of the air baffle is the same as that of the vertical section of the conveying pipe, so that fitting in closure is tighter, and air baffling effect is better.
Description
Technical field
The utility model relates to powder process equipment field, especially a kind of chute airlock.
Background technology
Because inner during vertical grinder work is the totally-enclosed negative pressure state, outer gas stream can not get into, in order to avoid influence the internal gas flow rotation direction.Special like this duty adopts special drawing-in device when making to the vertical grinder feeding, guarantee that outer gas stream does not get into inside.The funnel that the general picture of existing lock feeding device is just being put, superincumbent the hoarding of spent material self prevents that outer gas stream from getting into inside.But because material generally is building stones, hardness is big, when it falls to lock feeding device, bumps with the lock wind scoop easily; And produce a large amount of frictions with the lock wind scoop blanking time; Cause locking very easily wear-out failure of wind scoop, cause the vertical grinder shutdown maintenance, influence is produced.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure for the deficiency that solves above-mentioned technology, the effective and non-damageable chute airlock of lock wind.
In order to achieve the above object, the chute airlock that the utility model designed, it mainly comprises charging line, and charging line is obliquely installed, and on the upper inside walls of charging line, is provided with rotating bearing pin, and bearing pin is provided with deep bead.This structure is utilized the rotatable deep bead that is provided with, and deep bead and charging line inwall are not fitted when having building stones to get into; Realize the effect of lock wind; It is inner to prevent that outer gas stream from getting into, and when building stones got into, deep bead then can be opened at any time; And aperture changes along with the size of inlet amount thereupon, avoids causing because of aperture is excessive air leakage phenomena.
In order to improve lock wind effect, the shape of deep bead is consistent with the shape of the vertical section of the charging line of inclination, and when deep bead was closed, deep bead and charging line were fitted, and windproof effect is better.
The resulting chute airlock of the utility model is provided with rotating deep bead, deep bead and the applying of charging line inwall when having building stones to get on the charging line that tilts; Realize the effect of lock wind, it is inner to prevent that outer gas stream from getting into, and when building stones get into; Deep bead then can be opened at any time; And aperture changes along with the size of inlet amount thereupon, avoids causing air leakage phenomena because of aperture is excessive, causes the unapproachable situation of building stones because of aperture is too small.This deep bead can freely swing simultaneously, and the anticollision ability is strong, can improve its service life.In addition, the shape of deep bead is consistent with the shape of charging line vertical section, and it is tightr when closing, to fit, and windproof effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
As shown in Figure 1; The chute airlock that present embodiment is described; It mainly comprises charging line 1, and charging line 1 is obliquely installed, and on the upper inside walls of charging line 1, is provided with rotating bearing pin 2; Bearing pin 2 is provided with deep bead 3, and the shape of deep bead 3 is consistent with the shape of the vertical section of the charging line of inclination 1.
Claims (2)
1. chute airlock, it mainly comprises charging line, it is characterized in that charging line is obliquely installed, and on the upper inside walls of charging line, is provided with rotating bearing pin, bearing pin is provided with deep bead.
2. chute airlock according to claim 1 is characterized in that the shape of deep bead is consistent with the shape of the vertical section of the charging line of inclination.
