Abstract
The utility model provides an anti-blocking air lock. The air lock comprises a housing, an impeller, an impeller shaft and end covers, wherein the impeller is mounted on the impeller shaft; the end covers are fixedly mounted on the two sides of the housing; a neck protruding outwards is arranged in the middle of each end cover; a bearing hole and an oil seal hole are formed in the neck; the oil seal hole is close to one side of the housing; a cavity is formed between the bearing hole and the oil seal hole; the impeller shaft is fixed on the end covers through bearings; three evenly-distributed fan-shaped openings communicated with the outside are formed in the cavity; and the central angles of the fan-shaped openings are arranged as 50 DEG. In the operating process of the air lock, even if powder dust leaps out from gaps at the two ends of the impeller shaft, the powder dust is discharged from the fan-shaped openings along with the rotation of the impeller shaft and cannot leap into the bearings to cause the bearing to heat and be locked, so as to greatly prolong the service life of the air lock; and besides, the air lock has high processing manufacturability, and is convenient to mount.
Description
Technical field
The utility model relates to the corollary equipment in a kind of strength conveying and the dust ventilating net, more particularly relates to a kind of anti-blocking air sealer.
Background technology
Air sealer is the visual plant in strength conveying and the dust ventilating net, and it is widely used in the strength of husk rice, powder process, feed manufacturing machine and chemical industry, medicine, tobacco, metallurgy, cement and dusting equipment and carries.Its radical function is with material separated in discharger or the dust exhaustor or dust continuously in the exhaust to atmosphere pipeline, stop extraneous air to enter in discharger or the dust exhaustor simultaneously, so the anti-blocking performance of air sealer and air-tightness are major criterions of air sealer quality.At present; the structure of air sealer all is made up of housing, impeller, paddle shaft and end covers at two sides basically; poorly sealed when the paddle shaft two ends; perhaps since the oil sealing at paddle shaft two ends aging, damage, just can cause the small dust in the air sealer from the slit of sealing arrangement, to seal in the bearing at paddle shaft two ends, make the bearing can't normal operation; cause bearing heating and locking; must shut down and keep in repair, improve maintenance cost, and reduced greatly the service life of air sealer.In existing technology, the neck that also exists in end cap is opened a downward outlet, although this outlet also can realize making things convenient for dust to fly out and being unlikely to enter in the bearing, but the problem that exists is: it is too small that outlet is opened, being not easy to dust discharges, it is excessive that outlet is opened, and the undercapacity of end cap neck damages easily; Have again, opening down, its fabrication properties is poor, end cap boring is inconvenient, in addition, gives to install also to bring some inconvenience.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of dust to discharge convenience, end cap intensity is good, and the fabrication properties of end cap is good, the convenient anti-blocking air sealer of installing.
The utility model is achieved through the following technical solutions: a kind of anti-blocking air sealer, comprise housing, impeller, paddle shaft and end cap, impeller is installed on the paddle shaft, end cap is fixedly mounted on the housing both sides, is provided with outwards outstanding neck in the middle of the end cap, is provided with bearing hole and oil sealing hole in the neck, oil sealing hole is near housing one side, be provided with a cavity between bearing hole and the oil sealing hole, paddle shaft is provided with three uniform fan-shaped openings that communicate with the external world by on the bearing fixing end cap at described cavity place.
In the such scheme, convenient for the row's of making dust, the central angle of described fan-shaped opening is arranged to 50 °.
The anti-blocking air sealer of the utility model compared with prior art, its beneficial effect is:
1. owing to adopted three fan-shaped openings,, also can make dust be unlikely to seal in the bearing, cause the bearing heating locking along with the rotation of paddle shaft is discharged from three fan-shaped openings even if there is dust from the slit at paddle shaft two ends, to go here and there out.
2. this anti-blocking air sealer fabrication properties is good, easy for installation.
Description of drawings
Fig. 1 is the structural representation of the anti-blocking air sealer of the utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
Among the figure: 1. housing, 2. impeller, 3. end cap, 4. oil sealing, 5. bearing, 6. paddle shaft, 7. fan-shaped opening, 8. discharge gate, 9. end cap, 10. cavity.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the anti-blocking air sealer of the utility model is further described:
Fig. 1 is the structural representation of the anti-blocking air sealer of the utility model, among the figure, on the rounded bottom surface of the both sides of housing 1, be installed with end cap 3 and end cap 9, end cap 3 and end cap 9 and the housing 1 common inner chamber of forming air sealer, the centre of end cap 3 and end cap 9 respectively is provided with outwards outstanding neck, be provided with bearing hole and oil sealing hole in the neck, impeller 2 and paddle shaft 6 place the inner chamber of air sealer, the two ends of paddle shaft 6 are fixed in the bearing hole of end cap 3 and end cap 9 by bearing 5, oil sealing hole is near housing 1 one sides, in oil sealing hole, be provided with oil sealing 4, be provided with a cavity 10 between bearing hole and the oil sealing hole, be provided with three uniform fan-shaped openings 7 that communicate with the external world at cavity 10 places.
Fig. 2 is the A-A cutaway view among Fig. 1, and among the figure, convenient for the row's of making dust, the central angle of three uniform fan-shaped openings 7 is arranged to 50 °.
During work, dust is entered in the inner chamber of air sealer by the top of housing 1, along with impeller 2 rotate to the lower end time, just dust is discharged from discharge gate 8.The bearing 5 at paddle shaft 6 two ends adopts the end cap seal bearings, even rhegma appears in oil sealing 4 in running conditions, dust is gone here and there from the slit of rhegma in the cavity 10, also can be along with the rotation of paddle shaft 6 with material from three fan-shaped opening 7 smooth and easy discharges.The end cap seal bearing again more actv. stoped dust to enter in the bearing.
The anti-blocking air sealer of this kind makes the dust of going here and there out discharge more smoothly, and can not seal in the bearing owing to adopted three fan-shaped openings, causes the bearing locking, has improved the service life and the production efficiency of air sealer greatly.
