Abstract
The utility model provides a kind of device of supplying coal dust, is specially a kind of coal dust and revolves and scrape feeding machanism, the brown coal feed that the viscosity of using during applicable to thermal power generation is very large; Coal dust is by conical cap and enclose after gap between cylinder enters, rotation with scraper plate is rotated, by blanking, boring cylinder, rotating cone cylinder, blanking cone cylinder enters after blanking straight tube for next step: scraper plate is arranged on gear wheel by pin, bearing pin, two permagnetic synchronous motors drive scraper plate to move by reductor, pinion and gear wheel engagement, thereby scraper plate is played, revolve the effect of scraping; Gear wheel is suspended on base plate by suspension bracket, roller, ring-like guide rail; The method that employing is installed three cone cylinders one by one realizes the transmission of coal dust, wherein rotating cone cylinder is connected on gear wheel, between cone cylinder, there is overlapping part, can effectively prevent spilling of coal dust: blanking straight tube is suspended on cross flange by pull bar, conical cap is connected on cross flange by connecting bent plate.
Description
Technical field:
The utility model relates to a kind of device of supplying coal dust, the brown coal feed that the viscosity of using during applicable to thermal power generation is very large.
Background technology:
Coal dust feeding machanism is one of thermal power plant visual plant; even, stable, continuous Automatic-feeding that thermal power plant enters stove coal dust are the key factors that keeps Boiler Stable Combustion, guarantees unit safety operation and the saving energy; and China's existing coal dust feeding machanism complex structure, feed efficiency are low, the development of coal dust feeding device just seems particularly important for this reason.
Summary of the invention:
The purpose of this utility model is to design a kind of coal dust and revolves and scrape feeding device, when solving thermal power plant brown coal powder and entering stove evenly, stable, continuous Automatic-feeding problem.
The utility model solves the technical scheme that its technical problem adopts: coal dust is by conical cap and enclose after gap between cylinder enters, and with the rotation of scraper plate, rotates, and bores cylinder, rotating cone cylinder, blanking cone cylinder enter after blanking straight tube for next step by blanking.Scraper plate is arranged on gear wheel by pin, bearing pin, and two permagnetic synchronous motors drive scraper plate to move by reductor, pinion and gear wheel engagement, thereby scraper plate is played, revolve the effect of scraping.Gear wheel is suspended on base plate by suspension bracket, roller, ring-like guide rail.The method that employing is installed three cone cylinders one by one realizes the transmission of coal dust, and wherein rotating cone cylinder is connected on gear wheel, between cone cylinder, has overlapping part, can effectively prevent spilling of coal dust.Blanking straight tube is suspended on cross flange by pull bar, and conical cap is connected on cross flange by connecting bent plate.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Fig. 2 is that Fig. 1 removes conical cap top view afterwards.
Wherein, 1. pair permagnetic synchronous motor, 2 reductors, 3. scraper plate, 4. enclose cylinder, 5. connect bent plate, 6. gear wheel, 7. suspension bracket, 8. ring-like hanger rail, 9. rotating cone cylinder, 10. conical cap, 11. bearing pins, 12. pins, 13. blanking cone cylinders, 14. base plates, 15. pinions, 16. cross flanges, 17. blanking straight tubes, 18. pull bars, 19. blanking cone cylinders, 20. rollers.
The specific embodiment:
Coal dust is by conical cap (10) and enclose after the gap of cylinder between (4) enter, rotation with scraper plate (3) is rotated, and bores cylinder (13), a rotating cone cylinder (9), blanking cone cylinder (19) enter after blanking straight tube (17) for next step by blanking.Scraper plate (3) is arranged on gear wheel (6) by pin (12), bearing pin (11), two permagnetic synchronous motors (1) drive scraper plate (3) motion by reductor (2), pinion (15) with gear wheel (6) engagement, thereby scraper plate is played, revolve the effect of scraping.Gear wheel (6) is suspended on base plate (14) by suspension bracket (7), roller (20), ring-like guide rail (8).The method that employing is installed three cone cylinders one by one realizes the transmission of coal dust, and wherein rotating cone cylinder (9) is connected in gear wheel (6) above, between cone cylinder, has overlapping part, can effectively prevent spilling of coal dust.It is upper that blanking straight tube (17) is suspended on cross flange (16) by pull bar (18), and conical cap (10) is connected on cross flange (16) by connecting bent plate (5).
