Description
Technical field
It the utility model is related to solid particle or granular material feeding device technical field, more particularly to a kind of lock feeding
Device, suitable for industries such as building materials, chemical industry, metallurgy.
Background technology
In some grinding systems of the industries such as building materials, chemical industry, metallurgy, the operating pressure inside milling equipment is pressed with outside
Power is different, and the operation process requirement of milling equipment is the work(that drawing-in device has isolation grinding device interior pressure and external pressure
Can, that is, there is lock wind effect.Such as：The Vertical Mill of dry cement production line is negative pressure at work, inside Vertical Mill, the operation of Vertical Mill
Technological requirement has feeding and air locking function with the drawing-in device that Vertical Mill charging aperture is connected.
At present, the lock feeding device of dry cement production line raw material roller mill substantially has following two forms：
The first form, using traditional horizontal lattice wheel lock feeding, as shown in figure 1, being characterized in lattice wheel rotor
The central shaft 11 ' of component 4 ' is horizontally arranged, and after ore feeding lattice wheel, Fig. 1 signal sides are pressed through rotor assembly 4 '
To rotation, ore is fed into raw material roller mill from discharging opening 6 '.
One of the problem of form causes, as shown in figure 1, conveyer 15 conveys ore to charging aperture 5 ', conveyer
15 arrive the normal throw H of the cylindrical central sleeve 12 ' of rotor assembly 4 ', cause ore impact between the blade of rotor assembly 4 '
Close to the position of cylindrical central sleeve 12 ', and the solid accumulation body A of densification is formed in the position, for adhesional wetting materiel or the north
Winter is more so.Solid accumulation body A occupies the space of the feeding of rotor assembly 4 ', with solid accumulation body A increase, it will
Vertical Mill production capacity is caused to decline.At this moment need to shut down and clear up, solid accumulation body A is very rigid, it is necessary to post work pneumatic pick one point one
Point is destroyed, and is taken and laborious.
The two of the problem of form causes, the running orbit line part of the outmost turns of ore and the leaf of rotor assembly 4 '
Piece periphery running orbit coincide, particle easily it is jammed enter the blade periphery of rotor assembly 4 ' and the gap of the inwall of cylinder 2 ' in, from
And cause frequently card to turn, shut down, have a strong impact on the operating of Vertical Mill.Because the blade periphery of rotor assembly 4 ' and the inwall of cylinder 2 ' warp
State of wear is often in, lock wind gap is difficult to be effectively ensured, and causes inleakage big, leaked-in air will directly increase raw grinding
The load of system circulation blower fan, causes system energy consumption to increase therewith.
The undesirable using effect of traditional horizontal lattice wheel is always the problem of those skilled in the art is urgently to be resolved.
Later to improve this situation, part of cement manufacturing enterprise sets up number by transformation in the rotor lattice of traditional horizontal lattice wheel
Root chain, but this is also without solution root problem, and bring chain breakage, causes airlock feeding machine card to stop even direct band
Enter the new problem in Vertical Mill.Also Some Enterprises are simply dismantled traditional horizontal lattice wheel, and emission of baiting chute gradient is increased, by material
Sealing is formed, its result is exactly that inleakage is big, and blanking channel blocks because easily causing raw material greatly with horizontal direction angle.These measures
All do not solve problem well.
Second of form, as shown in Fig. 2 using sealing plate-type feeding lock feeding, be characterized in conveyer 15 with
Between raw material vertical-grinding, the material of a buffering supplied materials fluctuation enough is set to seal the platen type feeding machine 18 of storehouse 16 and one, material envelope storehouse is set
There is material-level measure unit 17, plate-type feeding 18 is arranged in seal casinghousing 19, and plate-type feeding 18 adjusts rate of feeding, all the time
Keep having certain material position in material envelope storehouse 16, can play and reduce the leakage wind action of Vertical Mill spout, while part solves the
The problem of stifled, card turns is glued in a kind of form in traditional horizontal lattice wheel lattice.
Sealing plate-type feeding although solves the problems, such as to leak out and blocking, but which installation workload is big, mounting cost
It is high；Moreover, the bearing and transmission mechanism of plate-type feeding 18 are under severe work condition environment, these positions are easily damaged
It is bad；In addition, plate-type feeding 18 is in seal casinghousing 19, the maintenance workers such as be unfavorable for checking it and refuel, change again
Make, so as to cause the use of the equipment, safeguard not in time, and it is high to ultimately result in overall use, maintenance cost.
The content of the invention
In view of this, technical problem to be solved in the utility model is：A kind of lock feeding device is provided, avoids filling
Put internal produce to glue stifled and form the solid accumulation body for causing feeding not smooth, reduce to occur to shut down handling phenomenon, it is ensured that continuous raw
Production.
