Description
Technical field
The present invention relates to a kind of Impeller airlock, a kind of high airtight column type Impeller airlock.
Background technology
At present, Impeller airlock is applicable to the handling of dry powdery and granule materials, is applied to the device for discharging of the equipment such as various grinding machine, dehydrator, drying tower, grain depot, feed bin；Owing to the material of conveying needs airtight and have in the system of high pressure, negative pressure and transmit, the requirement to air-tightness, gas leakage property and the discharge pressure of Impeller airlock is more and more higher；The current little poor air-tightness of Impeller airlock sealing surface, air leakage are big, do not reach the high gas-tight seal use requirement of the charging of vacuum drying apparatus, discharging.
The high airtight ball-type Impeller airlock (patent No. application: 2015200855673) of the patent of my application, there is ball-type impeller in it, ball-type valve body exists the problem being not easy processing, producing, and needs further to go to improve.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency overcoming existing Impeller airlock to exist, further improved on the basis of patent height airproof discharge gate (patent No.: 2014200000755), high airtight ball-type Impeller airlock (patent No. application: 2015200855673) of my application, provide a kind of simple in construction, the column type Impeller airlock that height that during operating, air leakage is few is airtight.
In order to achieve the above object, the present invention is achieved through the following technical solutions: high airtight column type Impeller airlock is made up of valve and power set.
Described power set are motor, or air motor.
Described valve is made up of valve body, column type impeller, bearing, pressure equalization means, sealing device.The rowland of valve side is for the connection of fixed valve with power set.
The top of described valve body has charging aperture, bottom to have discharging opening.
1, discharging opening, the mouth-shaped of charging aperture are round mouth shapes, or square opening shape.
2, discharging opening, charging aperture are provided with 15 road sealing devices at the position range of body cavity, and sealing device plays column type impeller and turns the gastight effect of sealing in the transhipment of body cavity inward turning.
3, sealing device is sealing ring, or labyrinth gland.
Described column type impeller is made up of valve shaft, barrel valve, storage bin, sealing device at the interior intracavity of valve body, column type impeller.
1, barrel valve two ends respectively connected valve shaft, and one end of valve shaft is fixed in the bearing on valve body, and the other end of valve shaft is connected with power set after extending valve body by bearing；When starting working, power set drive the work of column type impeller rotary motion.
2, the surface of barrel valve and the surface of internal cavity of valve body to be carried out surface high frequency quenching, electroplating surface process technique, then to be ground polishing, processing, to make barrel valve fully fit with body cavity after turn-milling cutting.
3, storage bin is at the inner chamber of barrel valve, and the Hatch Opening of storage bin is on the surface of barrel valve；Storage bin Hatch Opening shape is round mouth shape, or square opening shape.
4, the size of the material mouth of the charging aperture of size valve body of the Hatch Opening of storage bin, discharging opening.
5, the quantity of storage bin is 26；Storage bin is independent bin, is not communicated with between storage bin and storage bin.
6, on the barrel valve of the surrounding of storage bin Hatch Opening, 15 road sealing devices are installed；Sealing device is sealing ring, or labyrinth gland.
Described pressure equalization means is made up of passage, catheter pressure, sealing device in the side, both sides of valve body, pressure equalization means.
1, the both sides of valve body are correspondingly provided with 26 passages, and passage penetrates into body cavity, passage in valve body around sealing device is installed, described sealing device is sealing ring.
2, the passage of valve body both sides is connected by catheter pressure correspondence；Catheter pressure, by different pressures in the storage bin of column type impeller both sides, guides and reaches counterpressure, so can reduce the leakage rate of air, and the most steadily effect is played in the operating of column type impeller by the uniform pressure of both sides storage bin.
3, the installation quantity of pressure equalization means is 13 groups.
When high airtight column type Impeller airlock works: the charging aperture of valve and the ambient pressure of discharging opening have the different atmospheric pressure states of high pressure, vacuum, normal pressure.
Such as: during pressure equalization means work: the Hatch Opening of the storage bin of column type impeller is that left and right is corresponding, starts power set during work, and power set drive the work of column type impeller rotary motion.
1, the environment of charging aperture is vacuum state, and material charging aperture above valve enters the storage bin of column type impeller, and at this moment between material, space is that vacuum state gas is thin；Discharging opening is atmospheric pressure state, air discharging opening below valve enters the storage bin that column type impeller is empty, when column type impeller continues to rotate to passage position, the empty air in storage bin is entered by passage, catheter pressure in having the storage bin having material under vacuum state.
2, pressure equalization means is by the different pressures in the storage bin of column type impeller both sides, guides the counterpressure reached the storage bin of both sides within, and that so can reduce air lets out input, and also function to the operating of column type impeller steadily acts on.
3, column type impeller continues to rotate, and the material in storage bin, because of the importing of air, is just relatively easy to the discharging opening below valve and discharges；High airtight column type Impeller airlock the most so goes round and begins again the discharging that works continuously.
The present invention has the advantages that compared with existing Impeller airlock: high airtight column type Impeller airlock uses sealing device to increase, as the main body of sealing unit, column type impeller, the contact surface sealed, and it is high that it seals air-tightness, and gas leakage property is few；Different pressures in the storage bin of column type impeller both sides can be guided the counterpressure reaching the storage bin of both sides within, so can reduce the leakage rate of air by pressure equalization means, and that plays the operating of column type impeller steadily acts on；The simple in construction of high airtight column type Impeller airlock, can be adjusted according to the operating pressure of system, and external condition limits few, practical, applied range.
