Abstract
Disclosed is a self-purging impeller airlock comprising a machine body and a rotor portion, the two ends of a rotary shaft are arranged on a casing through bearings, and penetrate through impeller end plates and are fixed with an end cap respectively, a partial spilled material dust channel is disposed between the impeller end plates and the end caps, and a wear-resistant scraper blade is arranged between the impeller end plates and the end caps. A feed inlet and a discharge port of the airlock of the utility model are designed into rectangular shapes and forms with narrow top and wide bottom, and the distance from the feed inlet to the discharge port is between 5mm and 12mm. The length of the feed inlet is shorter than the length between the two end plates of a rotor, and the length of the discharge port is longer than the length between the two end plates of the rotor. Because the length of the feed inlet is shorter than the length between the two end plates of the rotor, the requirements on air impermeability above the airlock feed inlet are properly satisfied, thereby preventing the blockage phenomenon of the airlock, and the airlock gives full play to the air-lock discharging function of material discharging and receiving parts of a pneumatic conveying and dust-removal system.
Description
Technical field
The utility model relates to industries such as a kind of grain and oil, medicine, chemical industry, coal, cement and is used for air conveyer dust pelletizing system discharge and connects material partly working the air sealer that closes the wind effect, particularly a kind ofly can remove salvage stores between impeller end face and the end cap automatically, the self-cleaning type rotary airlock of avoiding the stifled phenomenon of card to take place.
Background technology
Existing rotary airlock, the air sealer that belongs to band baffle plate impeller, though its worker artistic skill guarantees that product design is up to state standards, but the gap between rotor and the casing still allows the partial material dust enter between impeller end face and the end cap, some material is higher or because of electrostatic adherence because of moisture, take care of the pence, can not drain smoothly, cause card stifled.Time one is long, and the air sealer end face is hot, damages machine, and is both dangerous, unhygienic again.
The inlet point of existing rotary airlock is consistent with the discharging opening internal diameter, and material releases has not smooth phenomenon to take place often.
Summary of the invention
The purpose of this utility model is that a kind of inlet point of design closes that wind is effective, material releases unimpeded, rotor and casing between do not block the self-cleaning type rotary airlock of stifled phenomenon.
The utility model is achieved through the following technical solutions above-mentioned design goal: the utility model is a kind of self-cleaning type rotary airlock, comprise body and impeller part, the turning cylinder two ends by bearing installation on casing, the impeller end plate is passed at the turning cylinder two ends, be fixed with end cap respectively, have one to overflow material channel between impeller end plate and the end cap, it is characterized in that the wear-resisting scraper plate blade that is fixed on the impeller end plate being provided with between impeller end plate and the end cap.
The stifled phenomenon of card takes place between air sealer rotor and the casing in order further to improve, make the material dust that overflows in time, directly release from the passage between impeller end face and the end cap swimmingly by discharging opening, the utility model is on the above-mentioned basis that is provided with wear-resisting scraper plate blade construction, the feed inlet and outlet of air sealer all is designed to rectangle, and be designed to up-narrow and down-wide, inlet point is shorter in length than the length between the impeller two end plates, and discharging opening length is longer than the length between the impeller two end plates.
After having taked abovementioned technology, the wear-resisting scraper plate blade that is fixed on the impeller end plate will be wiped off at any time attached to the material dust between end plate and the end cap, discharge from discharging opening, thereby make discharging channel unimpeded, material is drained easily, because inlet point is shorter in length than the length between the impeller two end plates, just the needs that guarantee that the above air-tightness of air sealer inlet point requires have been played, thereby guarantee that air sealer does not block stifled phenomenon, give full play to the wind discharging effect of closing at the discharge of strength conveying and dust pelletizing system and the part that connects material.

The specific embodiment
Embodiment 1
This air sealer comprises body and rotor portion, the turning cylinder two ends are installed on the bearing, and on casing, impeller end plate 4 is passed at the turning cylinder two ends by bearing installation, be fixed with end cap 3 respectively, between impeller end plate 4 and end cap 3, be provided with the wear-resisting scraper plate blade 5 that is used to remove the salvage stores dust.This wear-resisting scraper plate blade 5 is fixedly mounted on the impeller end plate 4, will scurry at any time in the gap between impeller end plate 4 and the end cap 3, and in time wipe off attached to the salvage stores dust between impeller end plate and the end cap, makes it discharge from this passage.
On the basis of said structure, the utility model is designed to rectangle with the charging and discharging mouth of air sealer again, and up-narrow and down-wide structure, goes out size disparity between inlet point and the discharging opening according to the gap of the different 5mm-12mm of having of air sealer model.Inlet point is shorter in length than the length between the impeller two end plates, and discharging opening length is longer than the length between the impeller two end plates.Because inlet point is shorter in length than the length between the impeller two end plates, played the needs that guarantee that the above air-tightness of air sealer inlet point requires just, give full play to the wind discharging effect of closing at the discharge of strength conveying and dust pelletizing system and the part that connects material.
Claims (2)
1, a kind of self-cleaning type rotary airlock, comprise body and rotor portion, the turning cylinder two ends of rotor portion by bearing installation on casing, the impeller end plate is passed at the turning cylinder two ends, be fixed with end cap respectively, it is characterized in that between impeller end plate and end cap, being useful on the wear-resisting scraper plate blade of removing the material dust.
2, according to the described self-cleaning type rotary airlock of claim 1, the feed inlet and outlet that it is characterized in that air sealer all is designed to rectangle, and be designed to up-narrow and down-wide, inlet point is shorter in length than the length between the impeller two end plates, discharging opening length is longer than the length between the impeller two end plates, and the gap of feed inlet and outlet between the two is 5mm-12mm.
