Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, column type of the present invention rotates valve core, including rotary shaft 4, and transition sleeve is connected with rotary shaft 4
3, valve body core 2 is coaxially connected with transition sleeve 3, and valve body core 2 is truncated cone-shaped, and the valve body 1 of annular, valve body 1 are set with valve body core 2
Endoporus be adapted with the outer wall of valve body core 2, between valve body 1 and valve body core 2 for gap coordinate；Valve body 1 be provided with charging aperture 8,
Discharging opening 13 and exhaust outlet 18；Charging aperture 8 is located at the top of valve body 1, and discharging opening 13 is located at the bottom of valve body 1.
Be machined with one or two stomata groups on transition sleeve 3, each stomata group by multiple " L " shapes 15 groups of aspirating hole
Into one end of multiple aspirating holes 15 in same stomata group is located on the same end face of transition sleeve 3, more in same stomata group
The other end of individual aspirating hole 15 is located on the same circumference of the side wall of transition sleeve 3；
Be machined with quantity and stomata group quantity identical storage hole group in the side wall of valve body core 2, same storage hole group by quantity with
The quantity identical storage hole 5 of aspirating hole 15 forms in same stomata group, and a storage hole 5 communicates with an aspirating hole 15, storage
Material hole 5 is stepped hole, and hole is relatively large in diameter in storage hole 5 towards transition sleeve 3, and filter screen 7 is connected with the step surface of storage hole 5.
Quantity and stomata group quantity identical wind disk are also set with rotary shaft 4, wind disk is not connected with rotary shaft 4.If
There was only a stomata group on transition sleeve 3, then wind disk only has one, if there are two stomata groups on transition sleeve 3, as shown in figure 1, adopting
With two wind disks, i.e. the first wind disk 6 and the second wind disk 12 in Fig. 1.Illustrated below by taking two wind disks as an example：In Fig. 1 institutes
In the column type rotation valve core shown, transition sleeve 3 has two stomatas between the first wind disk 6 and the second wind disk 12 on transition sleeve 3
Group, one end of all aspirating holes 15 is respectively positioned on transition sleeve 3 towards on the end face of the first wind disk 6 in one of stomata group, another
One end of all aspirating holes 15 is respectively positioned on transition sleeve 3 towards on the end face of the second wind disk 12 in individual stomata group, two stomata groups
In the other ends of all aspirating holes 15 be respectively positioned in the side wall of transition sleeve 3；Is machined with first wind disk 6 and the second wind disk 12
One mounting hole 16 and the second mounting hole 17, the first mounting hole 16 are located above the second mounting hole 17, the first peace on the first wind disk 6
Fill and the first vacuum port 9 is installed in hole 16, first steam port 11 is installed in the second mounting hole 17 on the first wind disk 6；Second
Second vacuum port 10 is installed in the first mounting hole 16 on wind disk 12, is provided with the second mounting hole 17 on the second wind disk 12
Second steam port 14.
When rotating valve core using column type of the present invention：First vacuum port 9 and the second vacuum port 10 are connect into centrifugal high pressure fan,
First steam port 11 and the second steam port 14 are connected with vapour source, and discharging opening 13 connects with transport pipeline；After centrifugal blower starts,
Charging aperture 8, storage hole 5, the mounting hole 16 of aspirating hole 15 and first form pumping path, and air-flow is installed on wind by the flow direction of charging aperture 8
Vacuum port on disk.After solid powder material is added at charging aperture 8, because powder air penetrability is small, vacuum is produced in storage hole 5
State, solid powder material are inhaled into storage hole 5, and under the stop of filter screen 7, solid powder material will not flow to air-flow
At centrifugal blower, but it is piled up in the less hole of the diameter of storage hole 5, completes the loading of solid powder material.Rotary shaft 4 drives
Transition sleeve 3 and the synchronous rotary of valve body core 2, the solid powder material in storage hole 5 follow rotation, when the rotation of storage hole 5 is to discharging
During 13 top of mouth, steam port, aspirating hole 15, storage hole 5 on wind disk connect with discharging opening 13, form gas channel, now, storage
The material less hole of diameter of hole 5 connects with discharging opening 13；Steam caused by vapour source enters in the gas channel, in vapour pressure masterpiece
Under, the solid powder material in storage hole 5 is flowed into transport pipeline after being mixed with steam.Rotary shaft 4 continues to rotate, when unloading
When the storage hole 5 of complete material connects with the exhaust outlet 18 on valve body 1, the steam remained in storage hole 5 is drained into by exhaust outlet 18
It is extraneous.Because the rotary speed of rotary shaft 4 is very fast, certain negative pressure is formed in storage hole 5 after remaining steam discharge, when storage hole 5
When being connected again with charging aperture 8, the negative pressure contributes to the loading of solid powder material.Rotary shaft 4 is continuously run, and solid can be achieved
The loading of powder material, mixing and transport with superheated steam.
When valve body core 2 and transition sleeve 3 continuously rotate, valve body 1 and wind disk do not rotate, by adjusting the axle on valve body 1
Xiang Li, the seal degree of column type rotary valve valve element can be adjusted.
Because the granularity of solid powder varies, in valve body core 2 drives powder material rotary course, to keep column type rotation
The sealing effectiveness of rotary plate, it is desirable to the solid particle of minimum diameter can not be entered in the contact surface of valve body 1 and valve body core 2, with
Prevent from destroying sealing surface, therefore valve body and valve element contact surface are designed as Cone fit face；Cone fit face has sealing well
Property, while have higher axiality inside, on cylindrical cone axis, convenient disassembly, part can be compensated automatically in rotary course
Abrasion the advantages that, but coning angle need to be avoided to self-locking angular region, therefore the cone angle alpha of valve body core 2 is more than 15 ° is less than 90 °（15°
<α<90°）.
Column type rotation valve core of the present invention allows minimum particle diameter to be 5 microns；Simultaneously as solid powder particle
Hardness is different, and to reduce the abrasion of contact surface, valve body core 2, transition sleeve 3, valve body 1 are made of high-abrasive material.Wear-resisting material
Expect for oxide ceramics（Zirconium oxide, aluminum oxide etc.）, non-oxide ceramicses（Carborundum, silicon nitride etc.）, mould steel, stainless steel,
The materials such as copper, copper alloy or copper graphite.
