Description

Novel vertical mill rocker arm device

Technical Field

The utility model belongs to the technical field of immediately, especially, relate to a novel immediately, grind rocking arm device.

Background

The vertical mill is an ideal large-scale grinding device, is widely applied to industries such as cement, electric power, metallurgy, chemical industry, non-metal ore and the like, integrates crushing, drying, grinding and graded conveying, has high production efficiency, can grind blocky, granular and powdery raw materials into required powdery materials, and has the structure of 1, a grinding disc: comprises a guide ring, a wind ring, a material blocking ring, a lining plate, a disc body, a scraping plate, a lifting device and the like; 2. grinding roller: the roller sleeve is an easily-worn part and is required to have enough toughness and good wear resistance; 3. the powder concentrator can be divided into three types of static, dynamic and efficient combined powder concentrator: a. the static powder concentrator has the working principle similar to that of a cyclone cylinder, has a simple structure, does not have movable parts and is not easy to break down. But the adjustment is not flexible, and the separation efficiency is not high; b. the dynamic powder concentrator is a cage which rotates at a high speed, when dusty gas passes through the cage, fine particles are brought in by air friction, coarse particles are directly blocked by the collision of blades, the speed of a rotor can be adjusted according to requirements, and when the rotating speed is high, the discharging fineness is finer, which is the same as the classification principle of a centrifugal powder concentrator. It has higher grading precision and convenient fineness control; c. the high-efficiency combined powder concentrator combines a dynamic powder concentrator (a rotary cage) and a static powder concentrator (guide vanes), namely, the cylindrical cage is used as a rotor, the guide vanes are uniformly distributed around the cylindrical cage, so that air flow uniformly enters a powder concentrator area from top to bottom, the separation of coarse powder and fine powder is clear, and the powder concentration efficiency is high. However, the powder concentrator has larger resistance, so that the abrasion of the blades is also large; 4. a pressurizing device: a hydraulic device, an accumulator; 5. a monitoring device: monitoring rocker arm and vibration; 6. the transmission device comprises: a motor, a reducer; 7. a water spraying system: reducing the temperature and stabilizing the material layer; 8. a coarse powder external circulation system: a hoist; the working principle is that a motor drives a grinding disc to rotate through a speed reducer, materials fall to the center of the grinding disc from a feed opening, move to the edge of the grinding disc under the action of centrifugal force and are rolled by a grinding roller, the crushed materials overflow from the edge of the grinding disc and are simultaneously brought into a high-efficiency powder selecting machine integrated with a vertical mill by high-speed upward hot airflow from a nozzle ring (an air ring), and coarse powder is separated by a separator, returns to the grinding disc and is ground again; and fine powder flows out of the mill along with the air and is collected in a dust collection device of the system, namely a product, wherein coarse-particle materials which are not carried by the hot air flow and metal pieces which accidentally enter sink from the air ring, are scraped out by a scraper plate and then are fed into the mill for grinding again through an externally circulating bucket elevator.
