Abstract
The utility model relates to a pneumatic conveying impeller type rotary feeding and discharging device, which is an airtight impeller type feeder used for conveying fiber-shaped materials (tobacco shreds, seed cotton) and plate-shaped materials (tobaccos, shavings). Thus, the good air tightness is ensured when blades and the material go through the position. Thereby, good airtight is ensured when the blade and the material go through the position. In addition, the sticky pads are stuck on the sponge blocks which have a certain of compressing swelling force; thus, the utility model can avoid the blocking phenomenon caused by that material is ridden and hung on the blades, the production efficiency can be greatly improved, a corresponding and smaller blower can be selected for supplying air, and the energy consumption can be reduced.
Description
The utility model relates to vane type rotary feeding, discharge device in the strength conveying, especially is air-tightness vane type rotary feeding, the discharge device of a kind of conveying fiber shape, sheet material.
Vane type rotary feeding, discharge device mainly are made of impeller and casing two parts, and the impeller that is provided with some blades rotates around horizontal S. A., and the power resources that axle rotates obtain in propulsion source and by drive path.Material is fallen between the blade of impeller from the top inlet point, wheel rotation, blade drives material and discharges from the bottom discharging opening, simultaneously by the contacting, cooperate, compress air-flow and material isolation of blade and casing inner wall face, and air leakage rate is limited in the as far as possible little scope.
At present, when conveying fiber shape (as pipe tobacco, unginned cotton) and sheet (as tobacco leaf, wood shavings) material, ride the rotation that hangs over jam impeller on the moving vane termination for preventing material, often leave the gap of 10～20mm between its blade outer end and casing inner wall face, and be fixed with the rubber block bar or belt strip seals with expectation at blade tip.But in actual use, the vertical center line of this charging and discharging mouth line of centers and the paddle shaft structure that is positioned at same vertical plane still can not avoid its jam to occur.Jam often appears between the lower left and casing inner wall face of impeller during work, in case jam occurs, just needs to get rid of, and influences work; And cause deformable blade, blade termination and body clearance to increase, air leak rate of air curtain is increased.This loader air-tightness is bad, and general newly formed product just reaches 30-40%, use one section after air leak rate of air curtain just reach 50-70%, even bigger.As: air quantity is 5000m in the pipeline
3/ h, behind rotary feeding, discharge device, air quantity just can leak to 7000～10000m
3/ h so just has influence on work efficiency, even can't guarantee the air-transport system normal operation.Solution in the engineering design, when using this charging, discharge device, the blower fan of usually selecting for use air quantity to surpass normal operation requirement 50-100% comes air feed, and low load with strong power causes energy dissipation very big.
The purpose of this utility model is to overcome the weak point in the above prior art, and provides that a kind of production efficiency is high, that make full use of the energy, its gap is little, air leak rate of air curtain is little and don't " feed inlet and outlet biasing, the flexible air hermetic rotary feeder " of jam.
Formation of the present utility model:
This is a kind of improvement design.The charging discharging opening is changed into offset, and promptly the vertical center line of the line of centers of feed inlet and outlet and impeller is designed to not in same vertical plane; Between the inner edge of the blade outer end of impeller and housing, cushion block, sponge block, sticky pad and air bleeder have been set up, make the distance between rigid blade outer end and the arc sticky pad narrow down to 2-3mm, add the blade outer end and be provided with wear-resistant block, and sticky pad is close to the blade outer end under gas pressure, has guaranteed that so just blade outer rim, material pass through the air-tightness in arc a district, arc c district.
The utility model further specifies middle in conjunction with the accompanying drawings embodiment:
Fig. 1 is in the prior art, the main TV structure section-drawing of " strength conveying rotary feeder ";
Fig. 2 is the main TV structure section-drawing of " feed inlet and outlet biasing, flexible air hermetic rotary feeder ".
Parts and position sequence number thereof in the diagram:
1, the housing of loader, 1-1 inlet point, 1-2 discharging opening, loader housing in 1 ' prior art,
2, sealing wear-resistant seal piece, the wear-resistant seal band of loader in 2 ' prior art,
3, the blade of impeller, 4, impeller, 5, the manifold screw, 6, pad, 7, screw, 8, cushion block, 9, sticky pad, 10, air bleeder, 11, sponge block, 12, axle.
As seen from Figure 1, when the vertical center line of the line of centers of feed inlet and outlet and impeller was positioned at same vertical plane, material easily stopped up in arc b district, so feed inlet and outlet of the present utility model changes offset into.
This " feed inlet and outlet biasing; flexible air hermetic rotary feeder ", mainly by housing, paddle shaft, wear-resistant seal piece on blade and the blade outer rim constitutes, it is characterized in that: for the outer rim of impeller 4 normal rotation and impeller vane 3 and the leak tightness between the loader housing 1, the feed inlet and outlet of this loader is a bias configuration, and the part inner face of housing 1 is provided with two cushion blocks 8, and with screw 7 with cushion block 8, housing 1 is fixed together, cushion block 8 inner faces are provided with sponge block 11, on the sponge block inner surface, be pasted with wear-resisting and sir-tight sticky pad 9, use the manifold screw sticky pad 9, sponge block 11, cushion block 8, housing 1 is fixed together.
The feed inlet and outlet bias configuration of said this loader means that the vertical center line of the line of centers of feed inlet and outlet and its paddle shaft 12 is not in same vertical plane.
The lower right and the position, upper left side of 8 impellers 4 in loader of said cushion block, cushion block 8 can be foundry goods, and castings material can be metal, also can be rigid plastic.
The shape of said sticky pad 9, material can be wear-resisting sir-tight fabric, also can be the flexible leather of a smooth side, also can be the rubber of a smooth side.
The material of said sponge block 11 can be sponge, also can be foamed plastic.
Wear-resistant block 2 on the said impeller vane 3 can be arranged on the middle part of blade 3, also can lock with screw respectively in both sides, the material of wear-resistant block 8 can be rubber, can be leather, also can be canvas belt, at the cushion block 8 of the foreign side of sponge block 11, housing 1 can be provided with several air bleeders 10.
Good effect of the present utility model:
Offset outlet arranges and in the lower right of impeller, the upper left side arranges cushion block, sponge block, and sticky pad and ventilation aperture make the distance between rigid blade outer end and the arc sticky pad narrow down to 2-3mm, add the blade outer end and are provided with wear-resistant block, flexible sticky pad Be close to the blade termination under Action of Wind pressure, so just guaranteed blade, material is by arc a district. The air-tightness in arc c district is good; Add that sticky pad is to stick on the sponge block, sponge block has certain compression, the expansion ability, when so just having avoided wheel rotation material in arc b district, the phenomenon of arc c district jam, avoid deformable blade, effectively reduced air leak rate of air curtain, production efficiency is greatly improved, can select to adapt, littler blower fan comes air feed, reduces the consumption of the energy.
