The particle rotation loader

(1) technical field

The utility model relates to the loader in a kind of particle transport system, relates in particular to a kind of PP of conveying and moulds the loader (air sealer) that pellet, PE are moulded pellet and grain particulate matter.Belong to the air-transport system technical field.

(2) background technology

Used feeding device in the air-transport system, need according to the character of material as: particle size distribution, bulk density, flowing power, chiseling property of mill etc. and pipeline import and export delivering gas pressure extent decide the feeding device of selecting which kind of type, the normal rotary feeder that adopts claims air sealer again in vacuum or the low pressure air-transport system.It is the critical component of air-transport system.Can Pneumatic conveyer successfully and effectively turn round, and depends on that at first can whether rotary feeder is suitable, satisfy the requirement of material properties and air-transport system.Usually when material be particle diameter during less than 200 purpose powders, common rotary feeder generally can satisfy the requirement of system's conveying.But when material is the particulate of particle diameter 200 orders～10mm or coarse grain granular substance, carry with common rotary feeder to occur the stuck and material shearing-crushing phenomenon of impeller easily, carry to system and bring very big difficulty.

(3) utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can prevent effectively that being applicable to of the stuck and material shearing-crushing phenomenon of impeller is thin, the particle rotation loader of the conveying of Coarse Aggregate.

The purpose of this utility model is achieved in that a kind of particle rotation loader, comprises housing, is horizontally installed with a rotor in the housing, and case top is provided with inlet point,

Described inlet point inner edge is provided with the antiseize device of one " W " shape, this antiseize device is to be protruded to be provided with to the center position of inlet point by the inner edge of described inlet point to form the projection that inner edge is similar to " W " shape, two the lowest point of described antiseize device inner edge are respectively arranged with an anti-sticking gap, and described antiseize device is arranged at material and leaves the inlet point place;

Also be provided with an equalizing device on the described housing, this equalizing device is an air extractor vent that is opened on the described housing shell wall, and this equalizing device is arranged on the housing shell wall in described inlet point the place ahead,

Described rotor comprises rotating shaft, blade, concave arc base plate and wallboard, described blade has some, some blades are the radial outer rim that is distributed in rotating shaft, described concave arc base plate is connected between adjacent two blades, described wallboard has two, one the first from left right side is fixedly connected in the rotating shaft, and captives joint with the two ends of concave arc base plate with described blade respectively, and described wallboard forms an enclosed rotor with blade and concave arc base plate.

The utility model by in the housing inlet point, adding " W " shape antiseize device and on the housing shell wall in inlet point the place ahead, add equalizing device, and rotor adopts the version of enclosed band concave arc base plate, after granule materials enters loader through inlet point, can discharge from discharging opening smoothly, reach the purpose of continuous feeding.Avoided the card of material in housing to block up and shred phenomenon.Specifically be mainly reflected in following aspect:

1, in the housing inlet point, add the antiseize device of " W " shape, thus make rotor in rotary course between blade and inlet point progressively engagement dodge and change (promptly forming scissors degree of lip-rounding point contacts) over to, be unlikely to the bad granular material of blade card of rotor.The anti-blocking effect of existing like this anti-sticking effectively prevents the blank entrance shape, effectively prevents the shearing-crushing (as plastic pellet: PP, PE, PVC and grain: soybean, corn etc.) of the stuck and particle of blade.

2, rotor adopts the version of enclosed band concave arc base plate, greatly reduces the leakage of gas and the chance that dust enters the axle envelope, the service life of having improved the air-tightness and the axle envelope of loader effectively; Rotor is taked concave arc base plate welded structure simultaneously, makes discharging more just smooth, and avoiding material to enter loader once more influences its serviceability, has improved transport efficiency.

3, on the housing shell wall in rotary feeder inlet point the place ahead, add equalizing device, can in time discharge rotary feeder inner high voltage gas or balanced system pressure, thereby the pressure in the rotary feeder is reduced, being convenient to material loads, improved the fullness rate of rotor lattice chambers, promptly improve the efficient that is full of of rotary feeder, be beneficial to the conveying of material.

In sum, each parts sealing gland of the utility model is good, is highly suitable for the conveying of thin, the Coarse Aggregate of positive and negative pressure air-transport system.Can prevent the generation of the stuck and material shearing-crushing phenomenon of impeller effectively, greatly reduce the leakage of gas and the chance that dust enters the axle envelope, make discharging more just smooth; Can in time discharge rotary feeder inner high voltage gas or balanced system pressure in addition, be beneficial to the efficient that is full of that improves rotary feeder.
