Abstract
The invention relates to the field of a high-speed centrifugal blower for air delivery, in particular to a high-speed air centrifugal blower for coal chemicals in the coal chemical industry, which comprises a left bearing box, a sealing ring, an upper half chassis, an impeller, a sealing shaft sleeve, a right bearing box, a coupling, a lower half chassis, an air inlet, an air outlet and a spindle, a single-stage impeller is adopted in the structure and is arranged in the middle of the spindle, the two sides of the impeller are provided with double-sided air intake holes, and blades of the impeller adopt twisted backward arc-shaped blades. By adopting the technical scheme, the size and weight of the high-speed blower are reduced, the air intake flow is smooth, and the working efficiency is improved.
Description
Technical field
The present invention relates to the high speed centrifugation blower field of carrying air, is that a kind of Coal Chemical Industry industry Coal Chemical Industry that is used for is used the high-speed air centrifugal blower.
Background technique
The air-blaster that is used for the Coal Chemical Industry industry, generally be secondary, the pressurization of three grades of impellers low speed (blower of rotating speed≤3000r/min), the blower fan volume is big; Heavy Weight, efficient is lower, and the blade shape results in stream of impeller is mobile poor; The quantity of inlet hole is one, causes charge air flow to have some setbacks.
Summary of the invention
The objective of the invention is: provide a kind of and can carry 1200～1900m
3The two air inlet high speed centrifugation blowers of the single-stage of/min air, efficient improves a lot.
Technological scheme of the present invention is: be made up of left bearing case, seal ring, first casing, impeller, sealing axle sleeve, right bearing case, coupling, second casing, intake grill, exhaust outlet, main shaft; Structure is the single-stage impeller; Impeller is contained on the main shaft neutral position; The impeller both sides are two-sided inlet hole, and the blade of impeller is made the back to curved blade of distorted shape.
Owing to taked technique scheme, the high-speed blower volume reduces, weight saving, and charge air flow is smooth and easy, has improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In the drawings: 1, left bearing case; 2, seal ring; 3, first casing; 4, impeller; 5, sealing axle sleeve; 6, right bearing case; 7, coupling; 8, second casing; 9, intake grill; 10, exhaust outlet; 11, main shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
In Fig. 1, first casing 3, the impeller 4 in second casing 8 drives main shaft 11 rotations through the high speed steam turbine, produces air quantity and blast; Air gets into from intake grill 9, impeller inlet 4 places that turn, and through the impeller work done, high-pressure air comes out to first casing 3 and second casing 8 from impeller, and casing is collected air and is rotated to 10 discharges of casing exhaust outlet; Sealing axle sleeve 5 is contained on the main shaft 11, and coupling 7 is connected on the end face of main shaft 11; Left bearing case 1, right bearing case 6 are on the both sides of first casing 3 and second casing 8, and impeller 4 is in the middle of main shaft, and such structure blower operates steadily, and casing is divided into first casing 3, second casing 8 two-part; Left bearing case 1 links in aggregates with right bearing case 6 and second casing 8; First casing 3 is formed labyrinth sealing with the sealing axle sleeve 5 on second casing 8 two ends and the main shaft 11 with sealing 2, prevents that atmosphere from getting in the casing.
