Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
As depicted in figs. 1 and 2, column type of the present invention rotates valve core, including rotary shaft 4, is connected with transition sleeve in rotary shaft 4
3, valve body core 2 is coaxially connected on transition sleeve 3, valve body core 2 is truncated cone-shaped, and the valve body 1 of annular, valve body 1 are set on valve body core 2
Inner hole be adapted with the outer wall of valve body core 2, between valve body 1 and valve body core 2 be clearance fit；Valve body 1 be equipped with feed inlet 8,
Discharge port 13 and exhaust outlet 18；Feed inlet 8 is located at 1 top of valve body, and discharge port 13 is located at 1 lower part of valve body.
It is machined with one or two stomata groups on transition sleeve 3, each stomata group is by 15 groups of aspirating hole of multiple L shapes
At 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 a aspirating hole 15 is located on the same circumference of 3 side wall of transition sleeve；
Quantity storage hole group identical with stomata group quantity is machined on the side wall of valve body core 2, same storage hole group is by counting
It measures storage hole 5 identical with 15 quantity of aspirating hole in same stomata group to form, and a storage hole 5 and 15 phase of aspirating hole
Logical, storage hole 5 is stepped hole, and hole is relatively large in diameter in storage hole 5 towards transition sleeve 3, is connected with strainer on the step surface of storage hole 5
7。
Quantity wind disk identical with stomata group quantity is further sleeved in rotary shaft 4, wind disk is not connected with rotary shaft 4.If
Only one stomata group on transition sleeve 3, then wind disk only one, if there are two stomata group on transition sleeve 3, as shown in Figure 1, adopting
The first wind disk 6 and the second wind disk 12 with two wind disks, i.e. in Fig. 1.It is illustrated by taking two wind disks as an example below: in Fig. 1 institute
In the column type rotation valve core shown, transition sleeve 3 is between the first wind disk 6 and the second wind disk 12, and there are two stomatas 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 a stomata group, two stomata groups
In the other ends of all aspirating holes 15 be respectively positioned on the side wall of transition sleeve 3；Is machined on 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 at 17 top of the second mounting hole, the first peace on the first wind disk 6
Dress is equipped with the first vacuum port 9 in hole 16, is equipped with the first steam port 11 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 equipped in 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: the 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 connect with vapour source, and discharge port 13 connects with transport pipeline；After centrifugal blower starting,
Feed inlet 8, storage hole 5, aspirating hole 15 and the first mounting hole 16 form pumping access, and air-flow is installed on wind by the flow direction of feed inlet 8
Vacuum port on disk.After solid powder material is added from feed inlet 8, because powder air penetrability is small, vacuum is generated in storage hole 5
State, solid powder material are inhaled into storage hole 5, and under the blocking of strainer 7, solid powder material will not be flowed to air-flow
It at centrifugal blower, but is piled up in the lesser hole of 5 diameter of storage hole, completes the loading of solid powder material.Rotary shaft 4 drives
2 synchronous rotary of transition sleeve 3 and valve body core, the solid powder material in storage hole 5 follow rotation, when the rotation of storage hole 5 is to discharging
When 13 top of mouth, steam port, aspirating hole 15, storage hole 5 on wind disk are connected to discharge port 13, airflow channel are formed, at this point, storage
The material lesser hole of 5 diameter of hole is connected to discharge port 13；The steam that vapour source generates enters in the airflow channel, in vapour pressure masterpiece
Under, the solid powder material in storage hole 5 is flowed into transport pipeline after mixing with steam.Rotary shaft 4 continues to rotate, when unloading
When the storage hole 5 of complete material is connected to the exhaust outlet 18 on valve body 1, the steam remained in storage hole 5 is drained by exhaust outlet 18
It is extraneous.Because 4 rotation speed of rotary shaft is very fast, certain negative pressure is formed in storage hole 5 after remaining steam discharge, when storage hole 5
When being connected to again with feed inlet 8, which facilitates the loading of solid powder material.4 continuous operation of rotary shaft is, it can be achieved that solid
The loading of powder material, mixing and transport with superheated steam.
In 3 continuous rotation of valve body core 2 and transition sleeve, valve body 1 and wind disk are not rotated, by adjusting the axis on valve body 1
Xiang Li, the seal degree of adjustable column type rotation valve core.
It because the granularity of solid powder varies, is driven in powder material rotary course in valve body core 2, to keep column type rotation
The sealing effect of rotary plate, it is desirable that the solid particle of minimum diameter cannot enter in the contact surface of valve body 1 and valve body core 2, with
It prevents from destroying sealing surface, therefore valve body and spool contact surface is designed as Cone fit face；Cone fit face has sealing well
Property, while having higher concentricity inside, on outer circle cone axis, and it is convenient for disassembly and assembly, part can be compensated in rotary course automatically
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 greater than 15 ° less than 90 ° (15 °
< α < 90 °).
Column type rotation valve core of the present invention allows the smallest particle diameter to be 5 microns；Simultaneously as solid powder particle
Hardness is different, and for the abrasion for reducing contact surface, valve body core 2, transition sleeve 3, valve body 1 are made of wear-resistant material.Wear-resisting material
Material be oxide ceramics (zirconium oxide, aluminium oxide etc.), non-oxide ceramics (silicon carbide, silicon nitride etc.), mould steel, stainless steel,
The materials such as copper, copper alloy or copper graphite.
