Abstract
A novel air chamber sealing rotary feeder of a rotary shaft comprises a shell body, shell body end caps, a rotary impeller, bearing supporting elements and an air chamber sealing box. The novel air chamber sealing rotary feeder is characterized in that the rotary impeller is installed inside the shell body, the two ends of the shell body are provided with the shell body end caps respectively, the shell body end caps are provided with the bearing supporting elements, and supporting and positioning of the rotary impeller are achieved through the bearing supporting elements on the two shell body end caps. The novel air chamber sealing rotary feeder of the rotary shaft is simple in structure, easy to machine and convenient to maintain.
Description
Technical field
The utility model relates to the rotation charging gear in the mass transport field, is specially a kind of Novel rotating shaft air chamber sealing rotary feeder.
Background technology
Rotary feeder is widely used in strength conveying and the dust removal by ventilation networking, one of indispensable equipment in feed and the dust removal by ventilation networking in the air-transport system, present rotary feeder generally adopts packing seal or mechanical seal, because the inboard air pressure of sealing place is higher than normal pressure far away, be easy to damage sealing member, cause poorly sealed, cause dust, foreign material to leak, contaminated environment, and when gas leakage dust enter easily the bearing seat at two ends, cause bearing failure, cause equipment not move.This equipment is mainly used in the air-transport system, also can use in the presence of feeding device in the normal pressure material-transporting system.
The utility model content
The technical matters that the utility model solves is to provide a kind of Novel rotating shaft air chamber sealing rotary feeder, to solve the problem that proposes in the above-mentioned background technology.
Novel rotating shaft air seal rotary feeder, comprise housing, housing end plug, rotary blade, bearings parts and air chamber sealing box, rotary blade is installed in the inside of housing, the housing two ends are equipped with housing end plug, the bearings parts are arranged on the end cap, and realize by the bearings parts on the two end cap support of impeller and location.
Further, be isolating construction between bearings parts and the end cap plate body, link to each other by reinforcing plate structure, when rotating shaft gas leakage leakage ash occurring, dust can not directly enter bearing box, improves bearing life.
Further, be free-running fit when paddle shaft passes end casing, need sealing, prevent gas leakage and leak ash, end casing at two ends is equipped with the air chamber sealing box, during work, access the pressurized air of 0.1 ~ 0.3MPa in the air chamber, the seal ring of air chamber sealing box both sides is compacted to be fitted tightly with paddle shaft, reach good sealing effectiveness, and when seal ring when wearing and tearing to a certain degree occur, gas leakage can not occur yet and leak grey phenomenon in the elastic compensating effect of seal ring.
Further, arranged two silk holes that are arranged symmetrically with on the air chamber sealing box, one is positioned at the top, is used for being connected with the compressed air inlet pipe road, and one is positioned at the below, is used for the dust of periodic cleaning air chamber, blocks with plug screw during work.
Beneficial effect: the utility model is simple in structure, and handling ease is easy to maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model gas chamber sealed structure figure.
The specific embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, Novel rotating shaft air seal rotary feeder, keystone configuration comprises housing 1, end cap 2, rotary blade 3, bearings parts 4 and air chamber sealing box 5, rotary blade 3 is installed in the inside of housing 1, housing 1 two ends installation end cap 2 with bolts, the pivoting leaf wheel shaft is installed by the bearings parts 4 on the end cap 2, air chamber sealing box 5 with bolts being installed on the end cap plate body 6, the space that air chamber sealing box 5 inner both sides are equipped with between air chamber sealing circle 9, two seal rings is air chamber 8.Arranged the silk hole of two symmetries on the seal box, one is positioned at the top and is air chamber ash-hole 11 for 10, one of air chamber induction openings are positioned at the below.During discharger work, pressurized air enters sealed air chamber 8 by air chamber induction opening 10, air chamber sealing circle 9 inner ring under the pressurized air effect expands, be close to paddle shaft 7, guarantee that gas and dust can not spill the gap between end cap plate body 6 and paddle shaft 7, during normal operation, the air chamber ash-hole is stifled tight with plug screw, open the cleaning of access compressed air spraying when needing in the cleaning air chamber dust.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
