Abstract
The utility model relates to a kind of Vertical Mill feeding airlocks, including shell, positioned at partition shell intracorporal rotor and be installed on the rotor, inlet port and outlet port are offered on the shell, it further include the both ends chain affixed with adjacent partition respectively, the partition is removably connected with tune seam plate close to one end of shell, and the outer edge for adjusting seam plate is away from 2 ~ 3mm of inner walls.The utility model had not only avoided the interference of partition and shell, but also material is sealed gap, and to realize lock wind, had effectively reduced the inleakage of vertical mill system by adjusting the setting gap 2 ~ 3mm between seam plate and inner walls；By the way that chain is arranged, chain swinging is driven when the rotor rotates, feed opening blockage problem caused by the aqueous height of material is avoided, is effectively guaranteed the running rate of grinding machine.
Description
Technical field
The utility model relates to cement manufacture plant technical field more particularly to a kind of Vertical Mill feeding airlocks.
Background technique
Currently, new dry cement technology is quite mature, but system air leakage problem is very serious, according to the country
The calibration statistics of over one hundred cement clinker production line, the air leak rate of air curtain of raw material vertical-grinding system are up to 25% or so.It wherein leaks out most
Place is not only to cause raw mill technology stability poor in raw material spout, also adds system and draws air quantity, increases system electricity
Consumption.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of Vertical Mill feeding airlocks, under can not only guaranteeing
Material mouth is not leaked out, and can be aqueous more to avoid material when block.
The utility model is achieved by the following technical solution, and provides a kind of Vertical Mill feeding airlock, including shell,
Positioned at partition shell intracorporal rotor and be installed on the rotor, inlet port and outlet port are offered on the shell, are also wrapped
The both ends chain affixed with adjacent partition respectively is included, the partition is removably connected with tune seam plate close to one end of shell,
The outer edge for adjusting seam plate is away from 2 ~ 3mm of inner walls.
This programme between two partitions by being arranged chain, when the rotor rotates, chain do not stop it is dynamic, so as to avoid object
Material sticks together after falling between two partitions, meanwhile, there are the gaps of 2 ~ 3mm between tune seam plate and inner walls, fall in material
After lower, which can be sealed by material, prevent from leaking out, in turn avoid gap it is too small and cause to adjust after long-time use seam plate with
The generation of shell interference phenomenon extends shell service life.
As optimization, the inlet port and outlet port eccentric setting.Such structure setting advantageously reduces transmission power damage
It loses, reduces equipment energy consumption.
Preferably, the partition is with the connection of seam plate is adjusted, the long hole that oriented inner walls extend is opened up on tune seam plate,
Seam plate is adjusted to connect by passing through the bolt of the long hole with partition.Such connection type not only facilitates the replacement for adjusting seam plate, but also is convenient for
Adjust seam the distance between plate and inner walls.
The utility model has the following beneficial effects: both being avoided by adjusting the setting gap 2 ~ 3mm between seam plate and inner walls
The interference of partition and shell, and material is sealed gap, to realize lock wind, effectively reduce the leakage of vertical mill system
Air quantity；By the way that chain is arranged, chain swinging is driven when the rotor rotates, feed opening blocking caused by the aqueous height of material is avoided and asks
Topic, is effectively guaranteed the running rate of grinding machine.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
It is as shown in the figure:
1, chain, 2, tune seam plate, 3, feed inlet, 4, shell, 5, partition, 6, discharge port, 7, hot air cavity.
Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
A kind of Vertical Mill feeding airlock as shown in Figure 1, shell 4 including horizontal positioned cylinder type are located in shell
Rotor and the partition 5 that is installed on the rotor, be equipped with hot air cavity 7 in rotor body, partition quantity is even number and mutually
Corresponding, partition is six in this implementation.Feed inlet 3 is offered at the top of shell 4, housing bottom offers discharge port 6, feed inlet 3
It is overlapped with the vertical centerline of 6 eccentric setting of discharge port, discharge port with shell central axes, the vertical centerline of feed inlet is along rotor
Rotation direction offset, when pan feeding, partial material directly forms partition and pushes, to reduce transmission loss.
The present embodiment further includes the both ends chain 1 affixed with adjacent partition 5 respectively, and when the rotor rotates, chain occurs
It swings, material is effectively prevent to be bonded.
Tune seam plate 2 is removably connected with close to one end of shell in partition 5, the outer edge for adjusting seam plate 2 is away from shell
2 ~ 3mm of inner wall.Partition 5 is to adjust and open up the long hole that oriented inner walls extend on seam plate 2 with the connection for adjusting seam plate 2, adjusts seam plate logical
The bolt crossed across the long hole is connect with partition.
When feeding, material is entered by feed inlet, and full of between adjacent two partition, seals tune seam plate and shell by material
Gap between inner wall plays lock wind effect.When rotor rotates, the hot wind in hot air cavity makes rotor surface high temperature, and chain exists
It does not stop when rotor rotation dynamic, be bonded material will not, so as to avoid blocking.By practical measuring and calculating, using this lock wind
After device, the air leak rate of air curtain of Vertical Mill spout is reduced to 5% hereinafter, the clogging of feed opening completely eliminates, and is effectively guaranteed mill
The running rate of machine.
Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to
It crosses or realizes that details are not described herein using the prior art；Above embodiments and attached drawing are merely to illustrate the technology of the utility model
Scheme is not limitations of the present invention, and the utility model is described in detail referring to preferred embodiment, this
Field it is to be appreciated by one skilled in the art that those skilled in the art institute in the essential scope of the utility model
The variations, modifications, additions or substitutions made without departure from the objective of the utility model, want by the right that also should belong to the utility model
Seek protection scope.
