Abstract
The invention relates to an anti-clogging powder feeding valve device. The device comprises a connecting flange mounted at the feed inlet of a valve. A blowing hole for supplying airflow to an internal sealing surface of the valve is formed in the body of the connecting flange, and runs through from the peripheral surface of the connecting flange to the end face of the connecting flange that is located in the valve body. According to the invention, high-pressure airflow is supplied into the valve body via the blowing hole in the connecting flange to sweep the powder at the internal sealing surface or sealing groove of the valve such that the powder accumulated at the sealing surface or the sealing groove is removed completely, thereby guaranteeing that the valve can be shut off easily and simultaneously preventing damage of the valve or spillover of materials due to blockage of the valve by materials. The invention is especially suitable for feeding of urea granules that are easy to deliquesce and cake, and certainly, can also be applied to feeding of other powdery materials.
Description
Technical field
The present invention relates to valve field, is specifically related to a kind of anticlogging powder conveying valving.
Background technology
At present, the urea product particle of nitrogen fertilizer plant's production can produce carbamide dust in course of conveying, and carbamide dust is easy
In deliquescence and form lump, easily gradually pile up to form blocking at the sealing surface of each powder conveying valve, under serious conditions also
Can cause that valve is stuck, urea is excessive.That is accumulated plugging problem urgent need to resolve of the carbamide dust at valve sealing face.
The content of the invention
To solve above-mentioned technical problem, the invention provides a kind of anticlogging powder conveying valving, the valve dress
Putting can be with accumulated plugging problem of the effectively solving carbamide dust at valve sealing face.
For achieving the above object, present invention employs technical scheme below：
A kind of anticlogging powder conveying valving, the device includes being arranged on the adpting flange at valve body charging aperture,
The adpting flange body is provided with valve body inner sealing surface the purge hole for being passed through air-flow, and the purge hole is by the connection method
Blue side face insertion is located at the end in valve body to the adpting flange.
Further, the end face that the adpting flange is located at outside valve body is provided with the cannelure with conveying pipe end joggle, institute
Stating purge hole is included by the adpting flange side face along the air admission hole of adpting flange radial direction insertion to the cannelure and multiple
The passage of the end in valve body is located at by the cannelure trench bottom direct puncture to the adpting flange.
Further, the passage is arranged along the cannelure flute length direction uniform intervals.
Further, axial spacing is reserved between the air outlet of the passage and the sealing surface.
The beneficial effect of above-mentioned technical proposal is mainly reflected in the following aspects：
(1) present invention is passed through high pressure draught in the valve body and in valve body by the purge hole on the adpting flange
Powder is purged at sealing surface or seal groove so that the powder at being deposited in sealing surface or seal groove is blown off, it is ensured that valve
Door can be shut easily, while preventing feed blocking valve from causing, valve is damaged or material is excessive.Present invention is particularly suited to
The easily conveying of the urea granules of deliquescence caking, naturally it is also possible to for the course of conveying of other powders.
(2) high pressure draught is entered in the cannelure by the air admission hole on adpting flange side face and causes high pressure draught equal
In the cannelure of adpting flange, high pressure draught is blown into valve body interior sealing to cloth by a circle passage of the cannelure trench bottom again
At face or seal groove, the powder at sealing surface or seal groove is blown off, it is ensured that pile up without powder at sealing surface.Present configuration letter
It is single, it is easy to process, efficiently solve the blockage problem of powder carry valve, it is ensured that the stable operation of valve so that equipment is tieed up
Shield cost is substantially reduced.
(3) in order that high pressure draught can smoothly blow to sealing surface by passage air outlet, the ventilation should be made
Hole air outlet and the reserved determining deviation of sealing surface, because passage air outlet leans on too near with sealing surface, the high pressure draught is on the contrary
Can blow less than the sealing surface.
Description of the drawings
Fig. 1 is mounting structure schematic diagram of the present invention.
Fig. 2 is connecting flange structure schematic diagram.
The implication of label symbol is as follows in figure：

Specific embodiment
In conjunction with the design feature of the description of the drawings present invention：
The device include be arranged on the charging aperture of valve body 10 at adpting flange 20, the body of the adpting flange 20 be provided with to
It is passed through the purge hole 21 of air-flow at valve body inner sealing surface 11, the purge hole 21 is by the side face insertion of the adpting flange 20 to described
Adpting flange 20 is located at the end in valve body.The present invention is circulated high pressure gas by the purge hole 21 on the adpting flange 20
Enter in the valve body 10 and powder at valve body inner sealing surface 11 or seal groove is purged so that be deposited in sealing surface 11 or close
Powder at sealing groove is blown off, it is ensured that valve can be shut easily, while preventing feed blocking valve from causing valve to damage
Or material is excessive.Present invention is particularly suited to the easily conveying of the urea granules of deliquescence caking, naturally it is also possible to for other powders
Course of conveying.
The end face that the adpting flange 20 is located at outside valve body 10 is provided with the cannelure 22 with conveying pipe end joggle, described to blow
Cleaning bottom of hole 21 include by the side face of the adpting flange 20 along the radial direction insertion of adpting flange 20 to the cannelure 22 air admission hole 21a with
And the passage 21b of multiple ends being located at by the trench bottom direct puncture of the cannelure 22 to the adpting flange 20 in valve body.
The passage 21b is along the flute length direction uniform intervals arrangement of the cannelure 22.
The high pressure draught is entered in the cannelure 22 by the air admission hole 21a on the side face of adpting flange 20 and causes high pressure gas
Stream is distributed in the cannelure 22 of adpting flange 20, and high pressure draught encloses passage 21b by the one of the trench bottom of the cannelure 22 again
It is blown at valve body inner sealing surface 11 or seal groove, sealing surface 11 or the powder at seal groove is blown off, it is ensured that without powder at sealing surface
Stockpile is accumulated.Present configuration is simple, it is easy to process, and efficiently solves the blockage problem of powder carry valve, it is ensured that valve
Stable operation so that cost of equipment maintenance is substantially reduced.
Axial spacing is reserved between the air outlet and the sealing surface 11 of the passage 21b.In order that high pressure draught
Sealing surface 11 can smoothly be blown to by passage 21b air outlets, the passage 21b air outlets should be made pre- with sealing surface 11
A determining deviation is stayed, because passage 21b air outlets lean on too near with sealing surface 11, the high pressure draught can blow on the contrary close less than described
Front cover 11.
