Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.
A center arch for comminutor, it is installed on the stirring main shaft at prilling bucket 2 middle parts, and described center arch 1 comprises body 11 and termination 12, and described body 11 is cylindrical, and one end of described body 11 is connected with paddle close installation; Described termination 12 is conical, and opening direction is connected with described body 11 other ends; The diameter of described body 11 is the 10-30% of described prilling bucket internal diameter.
Material enters in prilling bucket 2 from charging aperture, then by rabbling mechanism, carry out granulation for water atomizing system and power drive mechanism, after making from discharging opening discharging.But in the time of stirring-granulating, due to the effect of paddle rotation, near the position of stirring main shaft, the linear velocity of rotation is less, and the rollover effect of material is not obvious, easily piles up and causes granulation effect poor, and granulation is inhomogeneous.When stirring after main shaft place mounting center arch 1, center arch 1 position does not just have material, original this part material is by compared with the position at edge, increase linear velocity, the rolling successful of material, material is no longer piled up, improve the uniformity of granulation, guarantee product quality, improve yield rate, reduce production costs.
Described prilling bucket 2 tops are provided with for water atomizing system, and the described water atomizing system that supplies comprises annular feed pipe 3 and the multiple shower nozzles 5 that are arranged on described annular water supply 3 pipes.
In dry method pulverizing process, powder is in the time of water spraying atomization, and powder causes unstable product quality because water atomization is inhomogeneous, and production efficiency is low.When the multiple shower nozzles 5 that are provided with annular feed pipe 3 at prilling bucket 2 tops and be arranged on described annular feed pipe 3 are exactly from different perspectives powder to be sprayed water, the powder of diverse location can both absorb moisture, thereby make water atomization even, meet technological requirement, enhance productivity and also guaranteed constant product quality.
Described also comprises electronic flow valve for water atomizing system, and described electronic flow valve is arranged at the feed pipe road junction place being connected with described annular feed pipe 3.
The control of amount of water is very large to granulation for powders time and quality influence, when water deficient is to reduce harvest rate, extends the granulation time, makes powder excessively thick when excess moisture, increases drying process and power consumption.Described electronic flow valve is used for controlling the flow of water, thereby effectively controls amount of water, guarantee to add water homogenising and guarantee product quality more.
On described shower nozzle 5, be provided with a pressue device 4, described pressue device comprises shell, space dividing plate 43, spring 42 and gland 41 is in the enclosure set, shell is provided with water inlet and delivery port, described water inlet connects described annular feed pipe 3, and described delivery port is communicated in 5 of described sprays; Described spring 42 is arranged between space dividing plate 43 and gland 41, and described space dividing plate 43 supports described spring 42, and described spring 42 withstands described gland 41, in the time that water is come in from entrance, backs down described gland 41.
Described space dividing plate 43 supports described spring 42, and described spring 42 withstands described gland 41, in the time that water is come in from entrance, backs down described gland 41, greatly increased hydraulic pressure, thereby the better atomization of the water that shower nozzle is gushed out is enhanced productivity; In the time stopping adding water atomization, due to the effect of described spring 43, described gland 41 seals water inlet, can not produce drainage,, and described pressure apparatus 4 is simple in structure, convenience quick for installation, cost is low.
The discharging opening of described prilling bucket 2 is provided with discharge hole device, described discharge hole device comprises valve holder, valve gap and cylinder, described valve holder is arranged at the below of prilling bucket 2 downside discharging openings, described valve gap moves back and forth between described valve holder and discharging opening, when closed and described prilling bucket 2 fit tightly, described cylinder is installed in described valve holder, is connected with described valve gap, controls the open and close of described valve gap.
When comminutor completes after granulation powder process; need to emit the powder of having manufactured from discharging opening; so being set at discharging opening place, self-emptying mouth device facilitates discharging and discharging putty and affect whole job schedule not continuously; utilize the open and close of cylinder control valve lid; control the discharging of discharging opening, and described valve holder is used for supporting described cylinder.The structural design of this comminutor self-emptying mouth is simple, and discharging opening is by valve gap control discharging, and discharging valve gap is again by cylinder control, can self-emptying and continuous discharge and putty not.
Described discharge hole device also comprises preventing materials accumulation baffle plate is set, and described preventing materials accumulation baffle plate is connected with described valve gap, is arranged at described valve gap inner side; In the time that described valve gap is closed, the discharging opening side of described preventing materials accumulation baffle plate and described prilling bucket 2 is along leaving spacing.
Because prilling bucket wall has certain thickness, described preventing materials accumulation baffle plate can prevent that discharging opening from having material, described preventing materials accumulation baffle plate and described prilling bucket 2 are at regular intervals, can prevent granulation time, powder is piled up discharging opening, can prevent that again salvage stores after discharging from hindering closing to cause and being not closed completely of valve gap.
Described discharge hole device also comprises guide rod, and described guide rod comprises left guide rod and right guide rod; Described left guide rod and right guide rod are all through described valve gap, and one end is connected in described valve holder.
Because the size of described valve gap is larger, described left guide rod and right guide rod are equivalent to described valve gap motion guide rail, can make the power of described cylinder action on described valve gap more even, make the two ends of described valve gap and the better tightness of described prilling bucket, when described valve gap is opened, also be easier to.
Described valve gap surrounding is provided with airtight flexible glue.
Described valve gap surrounding is stained with airtight flexible glue, can fit tightly with described prilling bucket good seal performance and avoid Lou the phenomenon of material to occur.
Described center arch 1 is made up of aluminium alloy.
Aluminium alloy density is low, but strength ratio is higher, approaches or exceedes high-quality steel, and plasticity is good, can be processed into various section bars, has good electric conductivity, thermal conductivity and corrosion stability, industrial being widely used, and use amount is only second to steel, and cost is low.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes all will fall into protection domain of the present utility model.
