The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
Embodiment 1:
As shown in Figure 1, feeder is divided into bottom linkage section 4 three parts of feeder top linkage section 2, feeder main body 3 and feeder, and feeder upper and lower part linkage section 2 and 4 is installed on the feeder main body 3.The upper end of top linkage section 2 is a round section, matches with material storage tank 1, and the lower end is the square-section, matches with feeder main body 3; Feeder top linkage section 2 is connected with storage tank 1 by flange, and feeder bottom linkage section 4 is connected with material conveying pipe, realizes the conveying of material by carrier gas.
To shown in Figure 4, cylinder 5 is the blending box 8 of the material feeding chamber and the bottom on top with feeder body interior separated by spaces as Fig. 2, and cylinder 5 is around the axle left-hand revolution.Can be divided into four zones around the cylinder 5, that is, and the discharge zone of material receiving area T, seal area A, seal area B and remainder.Material in the storage tank enters the material feeding chamber of feeder main body 3 and is full of the interior metering feeder trough of cylinder 5 material receiving area T through feeder top linkage section 2; Arrive discharge zone behind the process seal area A under the rotation of cylinder 5, material leaves the metering feeder trough and enters blending box 8 under gravity and action of centrifugal force at this moment, is transported to the destination by feeder bottom linkage section 4 backs by carrier gas.In order to guarantee not leak material, the arc length of seal area A and seal area B should be at least greater than the width I of a metering feeder trough on the cylinder 5, and the gap a of seal area housing and cylinder 5 also should be less than the material particles diameter.
As shown in Figure 5, even in order to ensure to the glassware feed, the distribution of metering feeder trough should be satisfied certain requirement above the cylinder 5, and the metering feeder trough is many rows and distributes on cylinder, and present embodiment is an example with three rows.Each row metering feeder trough all equates with dislocation amount h of adjacent row's metering feeder trough, thereby the spacing of the adjacent metering feeder trough of same row is 3h, and the length of whole metering feeder trough is that the girth of cylinder is the integral multiple that same row upward measures feeder trough spacing 3h.The cylinder at a point that is this kind regular distribution all equates at the gross area of the metering feeder trough that the scope of same width along the circumferential direction comprises.Thereby can guarantee that the angle that feeding coal and cylinder turn over is directly proportional, control feeding coal and delivery rate thereby can rotate by index drum.The range of speed of cylinder 5 is between 3-30 r/min, and rotating speed is too high then can be owing to material can't be full of the accuracy that the metering feeder trough influences the metering feed at short notice.
As shown in Figure 2, gas purging device 6 is positioned on the feeder housing, gas purging device air inclusion surge chamber and gas purge hole, and the gas purging hole is to be positioned at the row of one on feeder shell aperture, along the rectilinear direction rectangular distribution parallel with cylinder axis.Purge gas enters the surge chamber of gas purging device 6 by pipeline 7, sprays to cylinder 5 through the purge hole on the feeder housing then, thereby blows down the material that sticks on the cylinder 5, realizes the cleaning to cylinder 5.
Material enters in the roller bearings 11 by cylinder and feeder shell can quicken the wearing and tearing of bearing, reduce the service life of feed valve, increase maintenance cost, though existing feeder has designed seal ring, but because material particles has certain rigidity, so seal ring is difficult to play the effective seal effect.As shown in Figure 6, this use is novel to have increased the vapor seal design on the basis of adopting the conventional seals method, blanket gas enters space between roller shaft and the housing 3-a by vapor seal with the pressure gas path 10, make and keep malleation in the bearing bore, after be blown into feeder inner chamber 9, stop material particles and dust to enter bearing 11 and then damage bearing like this, improved service life.
Embodiment 2: as different from Example 1: under the less situation of material storage tank 1, material storage tank 1 lower end is directly made and the cooresponding square-section of feeder main body 3 flanges, thereby omit feeder top linkage section.
The utility model provides evenly rotary displacement type dispensing mechanism accurately of a kind of metering feed.By the accuracy control of this feeder realization to feeding coal, guarantee the uniform and stable of feed simultaneously, this utility model not only can be used at the single-spray particle magnesium sulfur removal technology, can extensively be used in various even-grained particle feeding systems.
The above; only be embodiment of the present utility model; be not to any pro forma restriction of the present utility model; any those skilled in the art; in the scope that does not break away from technical solutions of the utility model; when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations; in every case be not break away from the technical solutions of the utility model content; to any simple modification, equivalent variations and modification that above embodiment did, all still belong to the scope of technical solutions of the utility model protection according to the utility model technical spirit.
