Abstract
The utility model provides a kind of cement grinding mill powder concentrator anti-condensation device, this device comprises powder concentrator and main dust-precipitator, powder concentrator is provided with First air entrance, Secondary Air entrance and air outlet, main dust-precipitator is provided with dust inlet and main smoke exhaust barrel, the air outlet of described powder concentrator docks with the dust inlet of main dust-precipitator, this device is also provided with a guide duct, the two ends of described guide duct are connected with the main smoke exhaust barrel of main dust-precipitator and the Secondary Air entrance of powder concentrator respectively, and the gas that main smoke exhaust barrel is arranged outward enters powder concentrator through guide duct by Secondary Air entrance; The utility model can effectively avoid powder concentrator because of the inside and outside temperature difference larger time very easily cause powder concentrator internal condensation and make the phenomenon of the sticky blade of material, the strong continous-stable running that ensure that grinding machine, and when improve grinding machine platform, anti-condensation Be very effective.
Description
Technical field
The utility model relates to field of cement production, specifically a kind of cement grinding mill powder concentrator anti-condensation device.
Background technology
Time prepared by cement, go out to grind cement material temperature at about 100 DEG C, when entering powder concentrator screening, material temperature is 85 ~ 90 DEG C, because of one of powder concentrator, Secondary Air all uses extraneous natural air, particularly in the winter of cold, the temperature difference inside and outside powder concentrator can reach 90 DEG C, the larger temperature difference very easily causes powder concentrator internal condensation, gap between wind blade is just stuck with paste full in 8 hours through the class of production that is everlasting by material, powder air quantity is selected sharply to reduce, grinding efficiency straight line declines, be forced to during platform lower, and each production class will only expect to clear up the material that blade is adhered in hour, when having a strong impact on grinding machine platform.
Utility model content
Very easily cause powder concentrator internal condensation time larger for the temperature difference inside and outside powder concentrator in above-mentioned prior art and affect the problem of grinding efficiency, the utility model provides a kind of cement grinding mill powder concentrator anti-condensation device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of cement grinding mill powder concentrator anti-condensation device, this device comprises powder concentrator and main dust-precipitator, powder concentrator is provided with First air entrance, Secondary Air entrance and air outlet, main dust-precipitator is provided with dust inlet and main smoke exhaust barrel, the air outlet of described powder concentrator docks with the dust inlet of main dust-precipitator, this device is also provided with a guide duct, the two ends of described guide duct are connected with the main smoke exhaust barrel of main dust-precipitator and the Secondary Air entrance of powder concentrator respectively, and the gas that main smoke exhaust barrel is arranged outward enters powder concentrator through guide duct by Secondary Air entrance;
Be provided with supporting leg bottom described main dust-precipitator, guide duct is fixed on the supporting leg of main dust-precipitator;
Described guide duct adopts diameter to be the pipe crimping of 800mm.
The beneficial effects of the utility model:
The cement grinding mill powder concentrator anti-condensation device that the utility model provides, can effectively avoid powder concentrator because of the inside and outside temperature difference larger time very easily cause powder concentrator internal condensation and make the phenomenon of the sticky blade of material, the strong continous-stable running that ensure that grinding machine, and when improve grinding machine platform, anti-condensation Be very effective;
The utility model high-temperature gas made full use of in the main smoke evacuation chimney that enters in air serves as the Secondary Air of powder concentrator, and improve wind-warm syndrome, economize energy, facilitates feasible, the little return that has high input, Be very effective;
The utility model makes about have the heat circulation of 1/3rd to enter powder concentrator, recycling in main smoke evacuation chimney, reduces to airborne release heat; Do not need to increase thermal hardware again to improve powder concentrator secondary air temperature, saved the energy, decreased labor strength, stable employment.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
Reference numeral: 1, powder concentrator, 2, First air entrance, 3, Secondary Air entrance, 4, main dust-precipitator, 5, main smoke exhaust barrel, 6, guide duct, 7, air outlet, 8, dust inlet.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further elaborated.
As shown in the figure: a kind of cement grinding mill powder concentrator anti-condensation device, this device comprises powder concentrator 1 and main dust-precipitator 4, powder concentrator 1 is provided with First air entrance 2, Secondary Air entrance 3 and air outlet 7, main dust-precipitator 4 is provided with dust inlet 8 and main smoke exhaust barrel 5, the air outlet 7 of described powder concentrator 1 docks with the dust inlet 8 of main dust-precipitator 4, this device is also provided with a guide duct 6, the two ends of described guide duct 6 are connected with the main smoke exhaust barrel 5 of main dust-precipitator 4 and the Secondary Air entrance 3 of powder concentrator 1 respectively, the gas of the outer row of main smoke exhaust barrel 5 enters powder concentrator 1 through guide duct 6 by Secondary Air entrance 3, in figure, the direction of arrow is airflow direction,
With perforate on the Secondary Air entrance 3 same level position of powder concentrator 1 in the main smoke exhaust barrel 5 of main dust-precipitator 4, set up a road guide duct 6, the hot blast in main smoke exhaust barrel 5 is introduced the Secondary Air entrance 3 of powder concentrator 1, to reduce powder concentrator internal-external temperature difference, avoid condensation; The Secondary Air entrance 3 of main smoke exhaust barrel 5 and powder concentrator 1 is apart from not far, and the gas of the outer row of main smoke exhaust barrel 5 has certain temperature, can reach 75.8 DEG C through measuring, quite close with the temperature 90 DEG C in powder concentrator 1; Guide duct 6 can adopt the pipe crimping of diameter Ф 800mm, utilizes the supporting leg of main dust-precipitator 4 as supporting, from the Secondary Air entrance 3 of main smoke exhaust barrel 5 opening access powder concentrator 1.
The utility model high-temperature gas made full use of in the main smoke exhaust barrel 5 that enters in air serves as the Secondary Air of powder concentrator 1, and improve wind-warm syndrome, economize energy, facilitates feasible, the little return that has high input, Be very effective.
