Abstract
The utility model relates to a raw materials immediately, grind roller hub seal structure, including centrifugal fan, its characterized in that: a centrifugal fan is arranged outside the raw material vertical mill, an air outlet of the centrifugal fan is connected with a main ventilating duct, a plurality of first branch pipes are arranged at the other end of the main ventilating duct, and the tail end of the main ventilating duct is plugged; a plurality of second branch pipes are respectively arranged on two sides of a grinding roller hub shell of the raw material vertical mill and connected with the first branch pipes through hoses to form forced air supply; the utility model discloses a mode of air feed is forced to centrifugal fan replaces the sealed wind mode of original grinding roller hub negative pressure, seals to the assembly bearing and protects, avoids the dust particulate matter to get into sealed internal damage sealed and then damage the bearing.
Description
Technical Field
The utility model belongs to the technical field of cement concrete production facility, concretely relates to raw materials immediately grinds grinding roller hub seal structure.
Background
In cement production, a large amount of raw materials need to be ground by using a raw material vertical mill, so that the materials are crushed to reach the required granularity, the ground materials are selected under the action of wind power, and the materials which do not reach the granularity are ground again after being settled. The raw materials grinds the inside dust that is full of immediately, the inside ash that very easily advances of its grinding roller hub pollutes, the sealed wind mode of negative pressure of present generally adopting seals the grinding roller hub of raw materials immediately, still can frequently appear the sealed damage of grinding roller bearing, the condition of grinding roller oil leak, it is sealed to change at every turn, it is intact all to discover the grinding roller hub, but the inside condition that can have a large amount of deposition of bellows, carry out the deashing and handle the back, the same condition will appear in the inspection of overlength time again, the dust can arouse the grinding roller bearing to damage, reduce its life.
SUMMERY OF THE UTILITY MODEL
To the problem, the utility model provides a raw materials grinds grinding roller hub seal structure immediately adopts the forced air supply mode to grind the bearing seal and protect immediately to the raw materials.
In order to realize the above function, the utility model adopts the following technical scheme: the utility model provides a raw materials immediately, grinds grinding roller hub seal structure, includes centrifugal fan, its characterized in that: a centrifugal fan is arranged outside the raw material vertical mill, an air outlet of the centrifugal fan is connected with a main ventilating duct, a plurality of first branch pipes are arranged at the other end of the main ventilating duct, and the tail end of the main ventilating duct is plugged; a plurality of second branch pipes are respectively arranged on two sides of a grinding roller hub shell of the raw material vertical mill and connected with the first branch pipes through hoses to form forced air supply.
Furthermore, the main ventilation pipeline is a galvanized steel pipe.
Further, the first branch pipe and the main ventilation pipeline are welded and fixed.
Furthermore, the number of the first branch pipes is four, and the first branch pipes are symmetrically connected to the main ventilation pipeline from top to bottom.
Furthermore, the number of the second branch pipes is four, and the second branch pipes are symmetrically connected to two sides of the grinding roller hub shell in a left-right mode.
Further, the centrifugal fan is arranged on a chute platform at the side of the raw material vertical mill deslagging scraper-trough conveyer.
To sum up, the utility model discloses a mode of air feed is forced to centrifugal fan replaces the sealed wind mode of original grinding roller hub negative pressure, protects assembly bearing is sealed, avoids dust particulate matter to get into sealed inside damage and seals and then damage the bearing.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
The utility model provides a raw materials vertical milling grinding roller hub seal structure as shown in figure 1, includes centrifugal fan, its characterized in that: a centrifugal fan 3 is arranged outside the raw material vertical mill 1, an air outlet of the centrifugal fan 3 is connected with a main ventilating duct 5, a plurality of first branch pipes 6 are arranged at the other end of the main ventilating duct 5, and the tail end of the first branch pipes is blocked; a plurality of second branch pipes 7 are respectively arranged on two sides of a grinding roller hub shell 4 of the raw material vertical mill 1 and are connected with the first branch pipes 6 through hoses 8 to form forced air supply.
Further, the main ventilation duct 5 is a galvanized steel pipe.
Further, the first branch pipe 6 and the main ventilation duct 5 are welded and fixed.
Furthermore, the number of the first branch pipes 6 is four, and the first branch pipes are symmetrically connected to the main ventilation duct 5 from top to bottom.
Furthermore, the number of the second branch pipes 7 is four, and the second branch pipes are symmetrically connected to two sides of the grinding roller hub shell 4.
Further, the centrifugal fan 3 is arranged on the chute platform 2 at the deslagging chute side of the raw material vertical mill 1, so that the length of a pipeline is reduced, the construction and installation are convenient, the material is saved, and the air supply effect is good.
Centrifugal fan 3 sends out the outside clean air of 1 outside of raw materials vertical mill through main air pipe 5, and get into four first branch pipes 6 respectively at its end, the hose 8, the second divides pipe 7, wherein the second divides pipe 7 symmetrical arrangement on grinding roller hub casing 4, make its inside air inlet even, avoid the raw materials vertical mill 1 inside high concentration dust gas to get into grinding roller hub casing 4 inside, reduce the dust and influence its seal structure, and the service life is prolonged, avoid frequently shutting down and carry out the deashing, reduce workman's amount of labour, and the production efficiency is improved.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
