Abstract
The utility model discloses an air lock for delivery pipes. The air lock mainly comprises a delivery pipe, and the delivery pipe comprises a feed inlet, a discharge outlet, a slideway area and a buffer area, wherein the feed inlet and the discharge outlet are vertically arranged, the slideway area is obliquely arranged, and the buffer area is horizontally arranged; the upper wall of the buffer area of the delivery pipe is provided with a rotating hinge pin, the rotating hinge pin is provided with a baffle, the length of the buffer area of the delivery pipe is consistent with the width of the delivery pipe. In the air lock, because the oblique delivery pipe is internally provided with a rotatable baffle, and the baffle is attached to the inner wall of the delivery pipe, and thus an air locking function is realized, thereby preventing external airflow from entering into the delivery pipe; meanwhile, the baffle can rotate freely, so that the baffle has strong anti-collision capacity; and through the arrangement of the buffer area, a part of stones can remain in the buffer area, thereby preventing stones from directly colliding with the baffle and further prolonging the service life of the baffle; in addition, since the length of the buffer area is consistent with the width of the delivery pipe, therefore, inertia of stones passing through the slideway area pushes the stones in the buffer area to enter into the discharge outlet, so that stones are discharged more smoothly.
Description
Technical field
The utility model relates to powder process equipment field, especially a kind of conveyance conduit 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 conveyance conduit airlock of lock wind.
In order to achieve the above object; The conveyance conduit airlock that the utility model designed; It mainly comprises conveyance conduit, and conveyance conduit comprises charging aperture and discharging opening, the slideway district that is obliquely installed and the horizontally disposed buffering area of vertical setting, on the upper wall of the buffering area of conveyance conduit, is provided with rotating pin; On rotating pin, be provided with baffle plate, rotating pin aligns with the lower wall of buffering area and discharging opening junction.This structure is utilized the rotatable baffle plate that is provided with, and baffle plate 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, baffle plate 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.
As optimization, the length of the buffering area of conveyance conduit is consistent with the width of conveyance conduit, and the inertia in the time of guaranteeing building stones through the slideway district is broken through buffering area and got into discharging opening, and mass transport is smooth and easy.
The resulting conveyance conduit airlock of the utility model is provided with rotating baffle plate, baffle plate and conveying pipeline inner wall applying 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; Baffle plate 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 baffle plate is free to rotate simultaneously, and the anticollision ability is strong, and the setting of buffering area can guarantee in buffering area, to stop the part building stones, avoids the direct impingement baffles of building stones, further improves the service life of baffle plate.In addition, the length of buffering area is consistent with the width of conveyance conduit, and the building stones that the inertia in the time of guaranteeing building stones through the slideway district promotes in the buffering area get into discharging opening, make discharging more smooth and easy.
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 conveyance conduit airlock that present embodiment is described, it mainly comprises conveyance conduit 1, conveyance conduit 1 comprises the charging aperture 2 and discharging opening 5, the slideway district 3 that is obliquely installed and horizontally disposed buffering area 4 of vertical setting; On the upper wall of the buffering area 4 of conveyance conduit 1, be provided with rotating pin 6; On rotating pin 6, be provided with baffle plate 7, rotating pin 6 aligns with the lower wall of buffering area 4 and discharging opening 5 junctions, and the length of the buffering area 4 of conveyance conduit 1 is consistent with the width of conveyance conduit 1.
Claims (2)
1. conveyance conduit airlock; It mainly comprises conveyance conduit; It is characterized in that conveyance conduit comprises charging aperture and discharging opening, the slideway district that is obliquely installed and the horizontally disposed buffering area of vertical setting; On the upper wall of the buffering area of conveyance conduit, be provided with rotating pin, on rotating pin, be provided with baffle plate, rotating pin aligns with the lower wall of buffering area and discharging opening junction.
2. conveyance conduit airlock according to claim 1 is characterized in that the length of buffering area of conveyance conduit is consistent with the width of conveyance conduit.
