Description
Technical field
The utility model belongs to airlock technical field, more particularly to a kind of anti-blocking anti-sticking blade of rotary airlock and impeller
Airlock.
Background technology
Airlock is part essential in Geldart-D particle and ventilating and purifying air system, he be wind net with wind net, wind net with
The logistics corridor that solid material between the different atmospheric pressures such as atmospheric environment exchanges, he has in carrying out material and exchanging engineering
While, the atmospheric pressure with different pressure or system environments are isolated, pressure is independent and mutually steady between ensureing each pressure field
Fixed, air and pressure are not revealed.The technological core of this device in the application, be exactly to realize exit seal first, do not allow because
Inlet and outlet pressure at two ends field is different and causes pressure difference, is internally formed air draught road in airlock, then just can guarantee that discharge, no
Then the air-flow of air duct drives material movement, so as to realize normal function.
Airlock form in market is varied at present, can by structure type, motion mode, type of drive, application scenario, be
The classification such as pressure of uniting.This several classification is again between each other mutually to cover intersection.Vane type, valve can be divided into substantially from structure

Material etc..Common engineering is mainly classified using upper with structure, and vane type is a kind of most important form, accounts for the market share
More than 99.5%.
The structure type and pass wind principle of existing rotary airlock are connect successively with feed inlet and outlet using multiple impeller storehouses
It is logical to realize splicing, discharge, using positioned at the feed bin blade radial end face into and out of the both sides between material mouth and housing radial circumference face
Minim gap, feed bin axial direction both ends end face and the side plane minim gap of housing two sealing airlock inlet and outlet pressure.This radially and
Axial gap is to ensure the key request of airlock sealing, and causes rotary airlock high energy consumption, the basic original of high fault rate
Cause.
There is certain interval between the vane tip and housing of existing vane type Blowing stopper, when airlock is run, impeller storehouse
In material under the influence of centrifugal force, a portion material is embedded between impeller radial end face and housing seal face, resistance
Hinder impeller to rotate, wear radial sealing surfaces, the working time is longer, and the wearing clearance of sealing surface is increasing, not only causes to close wind
Device current of electric increases, and reductor working condition changes, or even solid accumulation is stuck by blade on sealing surface, and stall occurs,
Motor is burnt, can also cause wind fortune system or dust pelletizing system pressure leakages, be shifted so as to which fan condition point occur, cause wind
Machine power consumption increases, and air-flow should be but compromised by the material that airlock excludes by, which causing, takes away, and reduces system operating efficiency.

As a further improvement, the sealing strip is polyurethane weatherstrip.
The utility model also provides a kind of rotary airlock, including housing, and anti-blocking anti-sticking blade, institute are provided with the housing
The gap that 14-15mm is left between blade and inner walls is stated, gap is left between the sealing strip and inner walls, it is described close
Radial clearance between strip of paper used for sealing and inner walls is 0.05-0.1mm, and the axial gap between the sealing strip and inner walls is
0.05-0.1mm。
The utility model can effectively prevent from getting stuck in use, leave 14-15mm gap between blade and inner walls
Block, this gap seals by sealing strip, left between specific sealing strip and inner walls 0.05-0.1mm radial clearance and
